Description

The invention relates to an arrangement of a vertical framework element and a framework component, according to the preamble of claim 1.

The invention also relates to a method for fastening a scaffold component having at least one connection head and a wedge to a vertical scaffolding element extending in the direction of a longitudinal axis according to the preamble of claim 10.

For example from the DE 24 49 124 A1 , of the EP 0 423 514 A2 , of the EP 0 276 487 A2 , of the DE 198 06 093 and the EP 0 936 327 A1 go framework structures with connection nodes of a modular scaffold, the stems are mounted in the axial direction in a pitch spaced perforated disks to connect scaffolding components in the form of connection, holding and / or support elements, such as longitudinal bars, crossbar and / or diagonals , Such a modular framework has been known for many years as the LAYHER Allround scaffolding system. The connection nodes or framework nodes of this modular framework are also known as LAYHER Allround Force Nodes.

In these connection nodes, a particularly stable, detachable connection between the connection heads having scaffolding components, in particular rod elements, such as scaffold tubes or scaffolding bars, and the scaffolding posts provided with the perforated discs is achieved. These terminal heads have an upper header and a lower header and a horizontal slot extending therebetween which is open forward and to the sides. The upper head part has an upper wedge opening and the lower head part has a lower wedge opening for a wedge which can be inserted through the wedge openings. The made of flat material, especially steel, existing wedge is permanently connected to the connection head. For this purpose, the wedge on its lower wedge end on a captive in the form of a rivet, which has laterally over the flat side surfaces of the wedge protruding rivet heads. Usually a flat-round rivet or a blind rivet can be used. Preferably, the Flachrundniet can be riveted by machine, while the blind rivet can be preferably riveted by hand. The upper wedge opening of the upper head part is as a longitudinal slot designed with a slot width which is only slightly larger than the thickness of the inserted with its lower wedge end by the upper wedge opening wedge. The rivet projects laterally with its rivet heads in a rivet width beyond the wedge, which is greater than the slot width of the longitudinal slot of the upper wedge opening. As a result, the wedge can not be pulled upwards out of the connection head, but only up to a stop of the rivet heads on an inner boundary surface of an upper wall part of the upper head part of the connection head. The lower wedge opening of the lower head part is larger than the upper wedge opening of the upper head part, and so large that the lower wedge end can be easily inserted with the rivet fastened there through the lower wedge opening.

To attach the connection head to a perforated disc of a scaffold handle, if this is not the case, first the wedge in the vertical direction pulled upwards and then back toward an upper outer surface of the scaffold component, in particular on an upper outer surface of a fixed to the Connection head connected rod element or scaffold tube, such as a scaffold bar, pivoted, preferably until the wedge abuts against said outer surface, so that the wedge is in a rearwardly folded mounting position. In this way, the wedge remains in a subsequent attachment of the scaffold component with its connection head on the perforated disc in said mounting position, in which the connection head are pushed in a substantially horizontal mounting direction without a blockage by the wedge on the perforated disc to a plug-on position can, in which the wedge openings of the connection head are perpendicular to the perforated disc, so that then the wedge, after its pivoting from the said mounting position into a vertical insertion position, due to gravity can go down, either immediately through an opening in the perforated disc and through the lower wedge opening in a locking position or initially on the top of the perforated disc, so that after subsequent displacement of the connection head on the perforated disc, into a sliding position, in which the lower wedge end of the wedge comes into coincidence with an aperture of the perforated disc, the wedge can then gravitationally pass through this opening and through the lower wedge opening in a locking position. In the respective locking position of the connection head by means of the wedge is positively locked with the perforated disc against unintentional release in all directions releasably locked. Starting from this locking position, the wedge can be wedged by means of a hammer blow from above on its upper hemming surface such that the connection head on itself on the outer surface of the scaffold support front bearing support surfaces of its upper head and its lower headboard with the scaffold and the wedge, with the perforated disc is clamped.

In practice, with certain of the aforesaid connection heads, it is possible not to retract the wedge to the rear in said mounting position after being pulled out to an upper extraction position in which the rivet abuts against said inner surface of the upper wall portion of the upper head portion pivot, but to pivot the wedge forward in a position in which the upper wedge end is above the connection head or on the front bearing support surfaces forward out. Due to the lever conditions that occur, the wedge can be caused by gravity and due to frictional forces remain in this forward pivoted position, provided that the scaffold member is held with the connection head in a substantially horizontal position. In this forwardly pivoted position, the wedge is supported on the one hand with a then lower wedge end face on an upper wall portion of the upper head portion of the connection head on a front first support point and on the other hand, based on this offset to the rear, at an inner rear second support point via its rivet or via its rivet heads on an inner wall of the upper head portion of the connection head from. It is also possible in practice for a part of these connecting heads, when the wedge is in such a forwardly pivoted position, with its lower and in this position rear wedge end to or on a rear wedge opening bounding the rear, to support transverse to the Aufsteckrichtung extending inner support bar. This support bar limits the wedge receiving space of the connection head to the front to prevent the wedge from slipping down when the connection head is not plugged onto a perforated disc and when the wedge is inserted through both wedge openings.

For the purpose of attaching the above-discussed frame components according to the prior art with its connection head on a perforated disc of a vertical scaffolding element, the above-described, in practice possible position of the wedge in a prior to attachment to the perforated disc pivoted forward position completely unsuitable. For in a case in which one would try one of the known from the prior art connection heads with his wedge in a forward over or in front of the Attaching the terminal head projecting position to a perforated disc of a scaffold post in a practical manner would, after contact of the wedge with its upper and in this position front wedge end with the outer surface of the scaffold and a continued movement of the terminal head with the so forward projecting Wedge in the radial direction of the scaffold stem, the wedge, before the connection head has reached the perforated disc, gravity fall with its lower end of the wedge down, with the result that the then fallen below crossing the horizontal slot wedge plugging the connection head block with his slit on the perforated disc and therefore would make impossible. The consequence would be that a continued attachment of the connection head with the aim of subsequent locking of the connection head with the perforated disc by means of the inserted through an aperture of the perforated plate wedge, not without a prior pulling up of the wedge to above its slot would be possible. Apart from this, for this purpose, the fitter would have to stay in a limited by his personal grip length maximum distance from the perforated disc, ie near the perforated disc on which the connection head is to be plugged in to pull the wedge up there can. This would make it impossible or at least difficult to assemble the scaffolding components from a secured position. For the rest, the fitter would have to do another attempt on Aufsteckversuch.

Therefore, in practice, the previously known scaffold component with connection heads, which are designed the same or similar as disclosed in the above-mentioned publications, with their connection heads exclusively under application a mounting method attached to the perforated discs, in which before attaching the connection head on the perforated disc of the wedge, as described above, first transferred to a rearwardly pivoted mounting position, and only then and in this mounting position of the wedge, the scaffold component with its connection head with its slot ahead, is placed on the perforated disc, and in which, after attaching the connection head to the perforated disc, the fitter, in a limited by his personal grip or arm length maximum distance from the perforated disc, the wedge must manually swing back into a vertical position, from where the wedge due to gravity can get into its locking position. According to this previous method, with these previous scaffolding components, especially scaffold bars or railing struts, no secured Vorbauen, especially no leading railing, starting from a secured position of the mechanic possible.

From the WO 97/27372 A is an arrangement for forming a scaffold node with cross brace and stand known, protrudes from the outer surface of which at least one radially extending to the stator axis projection in the form of a recesses having perforated disc. At the perforated disc, a scaffold component, such as a strut, are attached. The strut has at least one of its ends a wedge-shaped hook projecting transversely to the longitudinal axis of the strut on its outer surface. With this hook, the strut can be mounted in a recess of the perforated disc by the hook is inserted in a downwardly projecting position in the vertical direction from top to bottom in and through the recess. At the same end of the strut a detachable wedge is provided, which relative to the Hook is displaceable in the vertical direction. This wedge protrudes before the full insertion of the hook into a recess of the perforated disc over the contour of the hook down and laterally, so that this wedge end during vertical insertion of the hook into the recess on an edge of the recess or on the top of the perforated disc in a region adjacent to the recess for abutment, and wherein the wedge end is pushed upwards upon further insertion of the hook, and at the same time moved transversely relative to the hook, to a wedge position, in which said lower wedge end of the wedge, the recesses can happen and after passing through the recess can move laterally into a spread, in which a vertical or vertical movement of the strut end is locked up through the recess. The strut can be inserted from its end facing away from the scaffolding node from above, vertically down into the recesses of the hole disc fixed to the stand, wherein the wedge in his insertion of the hook into the recess permitting insertion position by its impact on the recess surrounding edge portion of the perforated disc moves. After the passage of the hook through the recess, the wedge moves by gravity or by pressure or shock on its upper end in a locking position in which it protrudes so far from the hook profile that in this spread position hook and wedge in an upward movement not through the recess can pass through and the wedge can only be moved out of this spread position by a force acting on it, for example, by a hammer blow from below on the lower end of the wedge. In this arrangement, the fitter can first hook the strut with the hook in the recess, so that the strut is already provisionally held in this position and possibly the scaffolding section is accessible, after which then falls by pushing the strut end in a horizontal direction to the stand of the wedge by gravity down. In the transitional phase in which the strut is only temporarily locked to the perforated disk via the hook inserted through a recess of the perforated disk, however, the strut can be lifted upwards again unhindered from the perforated disk. In the worst case, there may be an unintentional or accidental lifting of the only provisionally detained strut. This is a significant security problem. Incidentally, this construction and the associated fastening method is not or not readily applicable to scaffolding components and methods for their attachment, as disclosed in the publications mentioned above.

From the FR 2 912 476 A3 For example, a connector for elongate elements and a method of manufacturing this connector have become known. The connector comprises a connection head made of a metal strip with a wedge. The connection head is attached by means of the wedge in a conventional manner to a perforated disc.

From the EP 0 486 381 A1 An arrangement of a scaffold post and a scaffolding element, for example a crossbeam, has become known. Attached to the scaffold post is an upwardly open connector cup which has a cup rim extending vertically upwardly about the scaffold post, such that between the vertical cup rim and the scaffold post, a continuous upward expanding vertical annular gap is formed. The scaffolding element has at one end a clamping member with a front vertical hanging nose and with a front of this limited vertical slot in which a locking member for fixing the scaffold element by means of its clamping member on the connection cup is mounted displaceably guided in the vertical direction. The attachment nose of the clamping member is used for vertical suspension of the scaffold element in the vertical annular gap of the connection cup and for attachment of the scaffold element to the connection cup. For assembly, the scaffolding element is brought with its clamping member to the connection cup, in which case the locking member is allowed to fall in the vertical slot of the clamping member alone under the action of gravity in a lowermost position. Subsequently, the clamping member is vertically moved downwards in the direction of the cup rim of the connection cup such that the suspension nose can be transferred into the vertical annular gap between the outer edge of the framework stem and the inner edge of the vertical cup rim of the connector cup. In this case, the lower end of the locking member reaches the upper edge of the connection cup, so that in the course of a continued downward movement of the clamping member, the locking member is pushed by the upper edge of the connection cup up while the vertical hanging nose by simple gravity in the vertical ring slot between the connection cup and the scaffolding handle passes. Meanwhile, the locking member is pressed in the region of its lower end by a the insertion nose and the vertical slot of the clamping member inwardly bounding inner wall inward until the locking member finally comes free from the upper edge of the cup and falls by gravity in the vertical slot down. Then there is an intermediate position achieved in which the scaffolding element with its clamping member loosely "half-locked" by means of the locking member and the hanging nose on the connection cup of the scaffold stem that the clamping member and thus the scaffolding element not readily dug out of the connection cup, but still in the circumferential direction along moved the terminal cup and can be aligned in this manner angularly relative to the terminal cup. Subsequently, the locking member is knocked by a hammer blow on its upper end, after which the framework element is firmly locked to the connection socket of the scaffold handle. Reversion is reversed. After releasing the locking member by means of a hammer blow from below on its lower end, the locking member to allow a lifting of the scaffold element from the connection cup can be transferred in the vertical slot of the clamping member vertically upwards into an intermediate position in which the locking member with its lower end is supported on a shoulder formed in the vertical slot oblique surface, which is arranged in a direction away from the vertical hanging nose portion of the vertical slot and this limits to the rear.

From the GB 2 165 021 a connection head of a scaffold component has become known. The connection head has a vertically downwardly projecting Einhängezapfen for vertical hooking from above in not shown terminal-clamping socket of vertical scaffolding elements, also not shown. The connection head has a wedge captive connected thereto for locking the connection head of the scaffold component with the connection terminal block, not shown. The connection head has a widening upwards vertical wedge slot in which the wedge is movable relative to the terminal head. The Einhängezapfen is formed as a continuation of a bearing block having just above the upper end of the Einhängezapfens a recess which is bounded by an inner inclined surface which extends from the bottom to the top at an angle of 45 degrees. On this inclined surface, the wedge can be supported with its lower wedge end vertically downwards in a tilted position such that the upwardly protruding from the terminal head wedge member of the wedge is pivoted back to during assembly of the scaffold component to the terminal block, not shown, down Move the wedge to prevent it from locking.

From the US 4,840,513 A An arrangement of a scaffold post and a scaffold component in the form of a scaffold bar has become known. This arrangement has the features of the preamble of claim 1. US 4,840,513 A also discloses a fastening method according to the preamble of claim 10. On the scaffold post, a perforated disc is attached to which the connection head can be fastened by means of the wedge. The connection head has a captive connected to this wedge. The wedge has at its rear wedge edge in the region of its lower wedge end a rearwardly and outwardly open V-notch with an upper Kerbrand over which the wedge on an upper surface of the upper wedge opening of the upper head part delimiting wall portion of the upper head part can be supported if its wedge part projecting upwards out of the upper wedge opening is inclined obliquely backwards. In this position and tilt position of the wedge, the connection head can be plugged in a horizontal mounting direction forward on the orifice plate without a blockage by the wedge. The upper headboard has a vertically downwardly extending U-shaped tooth, which fits with radial clearance in a through hole of the through holes of the perforated disc. A fitter who holds the scaffold bar in the hand, when mounting the scaffold bar with its connection head on the perforated disc when the vertical tooth of the connection head falls into a desired through hole of the perforated disc, easily recognizable indicated that the connection head and the perforated disc are aligned relative to each other for locking by means of the wedge. After the tooth is positioned in the through hole, the upper wedge portion of the wedge projecting upwardly and obliquely rearwardly from the upper head portion, and thus the wedge, is pivoted forwardly to an upright position, the wedge automatically being constrained by the upper wedge opening of the terminal head and falls vertically down through the through hole of the perforated disc. Subsequently, the wedge is driven by a hammer blow on its upper wedge end vertically downwards, whereby the connection head is pressed with its vertical tooth against a rearwardly facing inner edge of the through hole of the perforated disc.

From the JP H11 62213 A An arrangement of vertical scaffolding posts and a scaffolding frame designed as a handrail has become known. The handrail is part of a rectangular frame, which is formed of horizontal and vertically extending vertical scaffolding tubes. On each vertical scaffolding post fasteners are attached in the form of connecting frames each consisting of a pair of vertical side plates and a vertical front plate connecting the vertical side plates. The connection frames are open upwards and downwards and have a U-shaped cross-section in a sectional plane formed perpendicular to the longitudinal axis of the respective scaffold post. At the upper corner regions of the frame, a connecting device with a connecting wedge for attaching the handrail or of the frame to a side plate of one of the connecting frames is fastened in each case. Each connection device has at its front end in the installed position a vertical lug which has a downwardly facing free insertion end and which is inserted vertically in the installed position from above into one of the connection frame. At its upper end, the insertion nose is fixed to two mutually parallel base plates of a base body between which a wedge receiving slot is formed, in which the connecting wedge is slidably received relative to the base body in a plane parallel to the main body plates (12) extending displacement plane. Each base plate is hook-shaped and has a lower nose-shaped wedge support part in the installed position. The nose-shaped wedge-supporting part extends in a forward direction towards the insertion nose and has support surfaces for a support pin attached to the lower end of the connecting wedge. The pin ends of the support pin protrude on both sides over the side surfaces of the connection wedge. Between the nose-shaped wedge support part and an upper connecting part of each base plate, an opening, which is open towards the vertical insertion nose, is formed in the form of a U-groove. The front end of the nose-shaped wedge support parts of the base body plates which point towards the insertion nose are connected to a wedge-contact support plate extending perpendicular to the main body plates, which is used to restrain an associated, rear end face of the connection wedge serves. To mount the handrail or the frame, the connecting wedge can be pulled upwards and supported by means of the abutment pin ends of its abutment pin on the support surfaces of the nose-shaped wedge abutment parts of the two base plates in a mounting position down. In this mounting position, the connecting wedge projects with its upper wedge end upwards beyond the two main body plates and at the same time is inclined obliquely forwards. For mounting mounting of the handrail or the frame is arranged with the respective vertical lug above each one of the U-shaped connection frame of the respective scaffolding handle, so that the respective vertical lug are inserted vertically into the enclosed by the respective connection frame insertion from top to bottom can. Subsequently, the handrail or the frame is guided vertically downwards such that the respective vertical lug is inserted vertically down into the respective insertion of the respective connection frame until a lower edge of the respective upper connecting part of the respective base plate on an upper edge of a Side plate of the respective connection frame rests in a mounted position. Subsequently or at the same time, the connecting wedge can be lifted off the respective wedge support part of the main body plates and vertically downwardly inserted into the respective wedge abutment support plate lying between the outer surface of the respective side plate of the respective connection frame and then the respective associated outer surface and wedged there ,

This wedge connection involves considerable security risks. Because due to the relatively low clamping forces against a lifting of the connecting device of this scaffold component in the vertical upward direction, especially in a loose, possibly not festgekeiltten or in use dissolving terminal wedge, it can lead to a vertical lifting of the scaffold component from a connection frame or from the connection frame, which means danger to life. A safe installation of this handrail by a fitter from a safe position or secured position of the mechanic to allow a secured Vorbauen the handrail, for example in the form of a leading railing, even if the fitter from this position or position with his Hand can no longer reach into the area of that connection frame of a handle on which the handrail with a lug of its insertion lugs to be plugged, is not possible.

That in the construction according to the JP H11 62213 A the above disadvantages or problems concerning a possible lifting of the scaffolding component vertically upward in conjunction with a resulting mortal danger may occur, also results from the JP H10 37455 A , This document relates to a similar arrangement of a scaffolding component in the form of a diagonal and vertical scaffolding tubes, to which corresponding, U-shaped connecting frame are attached. In order to avoid the said disadvantages or problems, in this scaffolding component of the basic body of this connection device, which is likewise formed from two parallel base plates, is provided with an additional locking lever in the region of the upper end of the vertical insertion nose in the installed position. The locking lever is pivotable about a horizontal transverse axis in the installed position relative to the base body. The axle ends facing away from each other in opposite directions the transverse axis of the locking lever are mounted in each case a slot opening of the respective base plate relative to this movable. The locking lever has a first, upper end of the lever and a second, lower end of the lever. The first, upper lever end is disposed at a first distance from the transverse axis and the second, lower lever end is disposed at a second distance to the transverse axis, which is much larger than the first distance. At the second, lower lever end of the locking lever extending transversely to the longitudinal axis of the locking lever extending pawl is formed. In a mounting position of the connecting device is located at the first, upper end of the lever locking lever, the wedge due to its own weight in a forward inclined tilt position and thereby pushes the first, upper end of the lever locking lever forward towards the vertical lug, while the second , the lower end of the lever is pivoted together with the pawl away from the vertical lug nose backwards. For the purpose of mounting this connection device on one of the two side plates of a connecting frame of a scaffold stem is on his investment pin on the support surfaces of the nose-shaped wedge support members of the base plates supporting connecting wedge with its upwardly out of the main body protruding upper wedge end to the at its bottom Keilende fixed investment pin pivoted relative to the base body to the rear until the investment pin free from the support surfaces of the nose-shaped wedge support parts of the main body plates of the body. Simultaneously with the Nachhintenschwenken the upper wedge end of the connecting wedge of the locking lever, with its upper, first end of the lever due to the greater weight of the lower lever portion of the locking lever at the front end edge the terminal wedge, with its upper end of the lever also pivoted backwards and at the same time with its lower, second end of the lever together with the forwardly projecting pawl forward, to a locking position in which the pawl engages under the lower edge of the side plate of the connecting frame and at the same time the terminal wedge with its front end surface on the rear end face of the locking lever lies flat and also at the same time the terminal wedge abuts with its rear end face on two the two base plates of the body traversing investment pins, so that then the connection device by means of the locking lever and the connecting wedge with the side plate of the connecting frame the scaffolding handle is positively locked so that the connecting device is not removable in any direction from the connecting frame, at least as long as the wedge is unlocked by a force acting on the wedge we so d that the pawl free from the lower edge of the side plate of the connection frame.

This construction is comparatively complicated and sensitive. Due to the stresses occurring during use or during handling of this scaffolding component, for example when this scaffolding component is dropped, it is possible for damage, in particular deformation of the blocking lever and / or the transverse axis bearing the blocking lever, and / or the oblong holes of the base body receiving the transverse axis. Plates are coming. This can lead to the pawl no longer being able to perform its function against lifting of the scaffolding component mounted on the connecting frame, which can result in considerable safety risks. Also in this construction is a safe installation by a fitter from a safe position or secured position of the installer in order to enable a secured Vorbauen the scaffolding component, for example in the form of a leading railing, even if the fitter can not reach from this position or position with his hand to the area of that connecting frame of a stem, on which the scaffold component is to be plugged with a lug of its insertion lugs, also not possible.

It is an object of the invention to provide an arrangement of a vertical scaffolding element and a scaffolding component of the type mentioned above and a method for attaching such a scaffolding component to a vertical scaffolding element, in which a mounting with wedge locking of the scaffold component with its connection head on the vertical Scaffolding element or on the projection particularly safe and yet relatively easy and easy from a secure position or secured position of a mechanic can be performed by this to secure a Vorbauen the scaffold component, for example in the form of a leading railing, even if the allow Fitter from this position or position with his hand can no longer reach into the region of that projection of the vertical framework element on which the scaffolding component with its connection head to be mounted horizontally.

This object is achieved with respect to the arrangement by the features of claim 1. Accordingly, the invention relates to an arrangement of a vertical scaffolding element and a scaffold component, which comprises at least one connection head and a wedge, for forming a detachable connection with the vertical scaffolding element, wherein on the extending in the direction of a longitudinal axis vertical scaffolding element is a transversely, so in a transverse direction, to the longitudinal axis of the vertical frame member extending and a recess in the form of an opening for insertion of the wedge-pointing projection is fixed, and wherein the connection head by means of the opening the projection plug-in wedge to form the releasable connection with the projection is positively lockable and can be clamped to the vertical framework element, and wherein the connection head has an upper head part with an upper wedge opening and a lower head part with a lower wedge opening, plugged for by the wedge openings Wedge, and wherein between the upper head part and the lower head part, a forwardly open horizontal slot for attaching the terminal head in a substantially horizontal Aufsteckrichtung forward on the projection is arranged, and wherein the horizonta Le slot is limited upwards and downwards with slot surfaces which extend on either side of a horizontal center plane of the horizontal slot, and wherein the connection head a horizontal slot over the horizontal slot above the horizontal slot arranged wedge support body with wedge support Has surfaces for vertically supporting the wedge in the region of its lower wedge end down against unintentional movement of the wedge vertically downwards into a blocking position, in which blocks plugging the connection head with its horizontal slot in the substantially horizontal Aufsteckrichtung forward on the projection and wherein the wedge-supporting body is disposed inside the terminal head, and wherein the wedge-supporting surfaces of the wedge-supporting body are formed such that a wedge portion of the wedge upwardly from the upper head portion on the upper Projecting head portion and that the wedge in an imaginary, perpendicular to the horizontal center plane of the horizontal slot, preferably in the transverse center of the connection head, extending vertical plane, in particular the vertical plane of symmetry of the symmetrically designed connection head, relative to the connection head in a forwardly inclined stop Pivot position is pivotable, in which the wedge part of the wedge protrudes from the upper head part up above the upper head part and protrudes forward in front of the upper head portion of the connection head or on this, when the wedge in the region of its lower wedge end or with its lower wedge end is supported on the wedge support surfaces of the wedge support body downwardly, and wherein the terminal head above the vertical support of the wedge downwardly enabling wedge support surfaces of the wedge support body disposed in the interior of the connection head wedge Having pivot abutment, and wherein the ke il-pivot abutment is designed such that the wedge in the region of its lower wedge end on the wedge-pivot abutment can be applied or rests when the wedge in the region of its lower wedge end on the wedge support surfaces of the wedge support body is supported at the bottom, and wherein the wedge with its upwardly projecting beyond the upper wedge opening wedge member to the rear and at the same time with its lower wedge end to the front about the wedge-pivot abutment is pivotable when the wedge in the region of its lower wedge end on the Wedge support surfaces of the wedge support body is supported downward and when the wedge is applied to the wedge-pivot abutment to achieve a release of the wedge such that the wedge gravity-assisted and / or spring-assisted automatically vertically downwards crossing the horizontal slot through the opening of the Projection can reach into a locking position into or through the lower wedge opening, in which the connection head with the aid of the wedge with the projection is positively locked to form the releasable connection, so that the connection head in any direction from the projection and only after unlocking the Keils by a force acting on the wedge of the protrusion is removable. The fact that the wedge support body and the wedge-pivot abutment are arranged in the interior of the connection head, results in a particularly compact design and it is an embodiment of the connection head or the scaffold component having this possible, which perfectly meets the needs of a Combinability or interchangeability of the scaffolding component with the previous scaffolding components allows.

According to an advantageous embodiment of the invention, the wedge-supporting surfaces of the wedge-supporting body can be arranged at a small vertical distance above the horizontal slot upwardly bounding wall parts, in particular above horizontal slot edges or slot surfaces of the slot. As a result, a particularly stable mounting intermediate layer of the wedge supporting on the wedge support surfaces of the wedge support body can be achieved. In addition, a secure release or release of the thus supported wedge can be achieved, so that the wedge with its lower wedge end can quickly and safely cross over the slot into the lower wedge opening.

The above advantages can be realized in a particularly favorable manner when the wedge-supporting surfaces of the wedge-supporting body at a vertical distance are arranged above the horizontal slot upwardly bounding wall parts, in particular above the horizontal slot edges or slot surfaces, which is smaller than half the slot height or half the slot height and the slot width formed in the vertical direction.

It is also of great advantage if the wedge-supporting body is arranged in the region of the horizontal slot rearwardly bounding vertical slot edges or surfaces of its slot bottom and / or in a rear portion of the horizontal slot. As a result, not only a further improvement in terms of the above advantages can be achieved, but also a particularly compact or space-saving solution, so that the connection and / or outer dimensions of the connection head can be adapted in a special way to the structural boundary conditions of the modular system.

According to a particularly advantageous embodiment of the invention can be provided that the wedge-supporting body limits the horizontal slot up with an upper slot surface. This not only a further improvement in terms of the above advantages can be achieved, but also advantageous opportunities for training a downwardly extending paragraph are created, by means of which a particularly advantageous orientation of the connection head relative to the perforated disc for the purpose of implementation about the same large positive and negative bending stresses when the connection head is plugged with its slot on the projection and clamped there with its wedge with the vertical framework element.

According to one embodiment of the invention can be provided that the wedge support surfaces inclined in the region of the lower head part, front, lower end of the wedge support body obliquely forward and downward and, in one, in particular imaginary, vertical plane considered vertical section, concave or rectilinear design are designed. As a result, the wedge, starting from its mounting position, particularly well managed and transferred easily and easily to a release position to form only relatively low frictional forces.

According to a particularly preferred embodiment of the invention can be provided that the wedge support body is designed with a receiving pocket for receiving and supporting at least one provided on the lower wedge end of the wedge wedge-part. As a result, the wedge in its transitional assembly position can be positively supported and consequently securely secured against shaking and / or vibrations.

When the receiving pocket, viewed in the vertical direction, is formed between the wedge-pivot abutment and the horizontal slot, the above advantages can be realized to a particular extent.

It may be particularly advantageous if the receiving pocket, viewed in a vertical section containing the imaginary vertical plane, has an inner contour which corresponds to a corresponding outer contour of one or the wedge part provided on the lower wedge end of the wedge. As a result, an optimally secure support of the lower wedge end can be achieved.

An embodiment that is particularly advantageous from a functional point of view can be achieved by arranging the wedge-pivot abutment in the region of the upper wedge opening and limiting the upper wedge opening to the rear and below. This not only the above advantages can be realized in a particularly favorable manner, but the wedge-pivot bearing can also act as a wedge-securing body delimiting the wedge receiving space, so that when the connection head is not attached to the perforated disc, but is handled separately, the wedge, when it is inserted through the upper wedge opening and through the lower wedge opening, can not fall down out of the connection head. In addition, advantageous possibilities can be achieved in this way by virtue of the fact that the wedge, when it is pulled sufficiently far upwards out of the upper wedge opening, extends completely backwards onto an outer surface of a component of the scaffold component firmly connected to the connection head, in particular to a rod part or rod part on a scaffolding tube, is pivotable. For this purpose, it may be provided that the wall part of the wedge-pivot abutment delimiting the upper wedge opening downwards and backwards is formed parallel to the said outer surface of said component of the scaffold component or parallel to its longitudinal axis. Preferably, the wedge-pivot abutment defining the upper wedge opening downwardly and rearwardly may be bounded overall by a horizontal outer surface which is at the same height as said outer surface of said component or which yourself in a height slightly below the height of the outer surface extends horizontally.

Conveniently, the wedge support body and / or the wedge-pivot abutment can be formed on the upper head part of the connection head and / or on a connection part of the connection head, to which a component, in particular a rod part, of the frame component is attached. As a result, particularly advantageous pivoting and release ratios can be achieved.

According to a particularly preferred embodiment of the invention can be provided that the connection head arranged on both sides of the vertical plane, in particular inner centering support surfaces for the wedge, between which the wedge is laterally supported in the region of its lower wedge end with little play when the Wedge on the wedge support surfaces of the wedge support body is supported. Thereby, a lateral tilting of the wedge passing through the upper wedge opening relative to the vertical plane can be minimized, whereby the wedge during the attachment of the connection head with its slot in a substantially horizontal Aufsteckrichtung on the projection and also when attaching the connection head with his Slot on the projection, a more precise and safer operation and release of the wedge is achievable.

A further improved securing of the wedge in its transitional mounting position against lateral tilting and correspondingly improved boundary conditions for actuating and releasing the wedge, can be achieved when the centering support surfaces below the upper wedge opening limiting wall portions of the upper head portion and / or are arranged below the wedge-pivot abutment.

The above advantages can be realized to a particular extent when the centering support surfaces are arranged in the region or at the level of the wedge support body or in the area or at the level of the receiving pocket and / or if the centering support surfaces one or limit the receiving bag laterally.

A still further improved in terms of the above advantages construction can be achieved in that at least two or exactly two forwardly extending centering support tabs are provided, which, bounded by the opposing centering support surfaces in a horizontal Distance or transverse distance, preferably parallel to each other, are arranged.

According to an advantageous embodiment of the invention can be provided that the upper wedge opening is limited on at least one side or on opposite sides with one or each with an upper wall portion of the upper head part, in the interior of the connection head with an inner, according to behind and below extending oblique wedge-leading edge is limited, at which provided in the region of the lower wedge end or at the lower wedge end captive, preferably a thickening, in particular at least one rivet head of a rivet, with a movement of the wedge relative to the connection head along feasible is or is led. This can be avoided or excluded jamming of the lower wedge end, which can be ensured that the wedge, starting from one after above and forward over the front end of the connection head or over the front vertical abutment support surfaces projecting pivot position, with a pivoting of the upper wedge end to the rear, with certainty on the wedge support surfaces of the wedge support body passes.

These advantages can be realized to a particular extent when the or each wedge-leading edge merges tangentially back and down into the receiving pocket.

According to a particularly preferred embodiment of the invention can be provided that the wedge in the locking position with a vertical, preferably substantially flat, contact surface of its rear wedge-front edge on a corresponding, the recess of the projection to the rear limiting, preferably substantially flat , Which is parallel to a vertical axis extending vertical wedge support surface of the projection can be applied, and that at the same time the wedge with an upper, preferably substantially flat contact surface of its front wedge front edge extending in the back and down in a extending first inclination angle to the vertical axis along a first oblique axis, flat against a corresponding, upper, preferably substantially flat, rearwardly facing, in particular inner, wedge support surface of the upper head part can be applied, which also in the direction of the rear and down in the extending first inclination angle to the vertical axis along the first oblique axis, and that at the same time the wedge with a lower, preferably substantially flat, contact surface of its front wedge front edge extending in the back and down direction at a second inclination angle to the vertical axis a second Oblique axis extends, surface on a corresponding, lower, preferably substantially flat, rearwardly facing, in particular inner, wedge support surface of the lower head part can be applied, which is also in the back and down direction in the second inclination angle to the vertical axis extends along the second axis of inclination or that the wedge in the locking position, at the latest when it is braced with the vertical frame element, with a vertical, preferably substantially flat, contact surface of its rear wedge-front edge surface on a corresponding, the recess of the projection to the rear limiting , Preferably, substantially planar, extending parallel to a vertical axis, extending vertical wedge support surface of the projection, and that at the same time the wedge with an upper, preferably substantially flat, contact surface of its front wedge front edge extending in the direction back and down in extending at a first angle of inclination to the vertical axis along a first oblique axis, flat against a corresponding, upper, preferably substantially flat, rearwardly facing, in particular inner, wedge-support surface of the upper head part, which also in the direction of the rear and extending at the first inclination angle to the vertical axis along the first oblique axis, and that at the same time the wedge with a lower, preferably substantially flat, contact surface of its front wedge front edge extending in a backward and downward direction at a second inclination angle to the vertical axis along a second oblique axis extends, flat against a corresponding, lower, preferably substantially flat, rearwardly facing, in particular inner, wedge support surface of the lower head part, which also in the direction extends rearwardly and downwardly at the second inclination angle to the vertical axis along the second oblique axis. As a result, a particularly simple, easy and also over a long time particularly secure attachment with favorable pivoting and guiding conditions with minimal wear of the connecting parts, in particular the perforated disc can be achieved.

According to an alternative embodiment, it can be provided that the outer projection part has a, preferably substantially planar, inwardly pointing, vertical wedge support surface for the wedge, which limits the arrangement or opening, preferably in the transverse direction, to the outside and which extending between the upper boundary surface and the lower boundary surface of the projection parallel to or along or in the direction of a vertical axis, and that the upper head portion on a transversely inner side of the passage one, preferably substantially flat, transversely outwardly facing, itself extending parallel to the vertical axis, vertical, upper wedge support surface for the wedge, and that the lower head portion on a transversely inner side of the passage one, preferably substantially flat, transversely outwardly facing, parallel to the vertical axis extending, vertical, lower wedge Stut z-surface for the wedge, and in that the wedge has a first wedge leading edge which is one, preferably substantially flat, outwardly facing obliquely inwardly and downwardly at an inclination angle to the vertical axis along a sloping axis Contact surface which, when the wedge is in the locked position and the connection head by means of the wedge with the vertical Scaffold element is braced and / or when the wedge is in the locking position, only locally, preferably in the region of an upper recess edge of the recess of the projection, in particular point or line, rests against the vertical wedge support surface of the outer projection part, and that the wedge has a transversely inwardly facing second wedge leading edge having a, preferably substantially planar, vertical axis extending vertical contact surface with the vertical upper wedge support surface of the upper header and with the vertical lower wedge support surface of the lower head portion such that the vertical contact surface of the wedge on both the vertical upper wedge support surface of the connection head and on the vertical lower wedge support surface of the connection head, preferably flat, fitting, relative to both the vertical upper wedge support surface and to the vertical lower wedge support surface, parallel to or along or in the direction of the vertical axis, is displaceable.

This results in the impact of the wedge to only relatively low frictional forces, so that the impact of the wedge is comparatively easy, in particular by a hammer blow, possible. Furthermore, it can be avoided that even after a multiple impacting and loosening of the wedge with each retraction of the wedge always a secure clamping of the connection head with the projection of the vertical framework element or with the vertical framework element is possible or guaranteed.

According to an advantageous embodiment it can be provided that the horizontal slot in the direction of its slot bottom and / or in the region of its slot bottom and / or in a rear portion of the horizontal slot with a downwardly formed in the insertion region for the projection horizontal upper slot surfaces the horizontal slit extending paragraph of the upper head portion is defined, which is bounded below with a horizontal upper heel slot surface of the horizontal slot, wherein in the support position above the horizontal upper boundary surface of the outer projection portion of the projection arranged paragraph in the support position and at least when the wedge is in the locking position and the connection head is braced by means of the wedge with the vertical frame member or already when the wedge is in the locking position, with its parallel z U of the horizontal upper boundary surface of the projection extending paragraph slot surface, supported on the upper boundary surface of the projection surface, so that the first distance of the upper end of the upper abutment support surface of the upper head portion of the horizontal center plane of the projection and the second distance of the lower End of the lower abutment support surface of the lower head portion of the horizontal center plane of the projection are the same size. As a result, identical or symmetrical force and torque transmission ratios and correspondingly the same static characteristic values of the connection can be achieved with a positive upward bending load and with a downward negative bending load. Furthermore, this defined investment, positioning, management and power transmission ratios can be realized. In particular, thereby lateral forces better be transmitted from the terminal head to the projection. In addition, the voltages in the connection head can be kept particularly low by the measures mentioned. Due to a reduced clearance between the horizontal slot and the projecting projection in this and the flat contact conditions of the inserted into the horizontal slot projection both downwards and upwards, the projection can be "taken along" well in bending stresses both down and up when the connection head having scaffolding member, such as a scaffold bar, is bent downwards or upwards, because the projection can now both down and up advantageous in the bending contribute to such that both down and up greater bending forces or moments are transferable, as was previously the case. This construction allows a connection node or a connection with better overall static characteristics.

According to a particularly preferred embodiment, it may be provided that the horizontal center plane of the horizontal slot and the horizontal center plane of the projection in the support position substantially coincide or form a common plane. As a result, a further improvement in terms of the above advantages can be achieved.

According to a preferred development it can be provided that the heel is provided with lateral insertion bevels. These may each be provided with an inclined surface extending from the horizontal paragraph slot surface obliquely upward and laterally to the respective vertical outer surface of the respective upper side wall portion can extend. This makes it easier to attach or slide the connection head in a direction perpendicular to the vertical plane or perpendicular to the transverse direction and perpendicular to the vertical axis or in a tangential direction to the projection or to the perforated disk. This is particularly advantageous if it is not possible for a plugging or pushing the connection head in the forward direction or in the radial direction of the projection or on the perforated disc, for example because there is no sufficient space available or because with The scaffold component already provided with the connecting head already at its end facing away from the connection head, in particular by means of a second connection head and / or a second wedge already on a projection or on a perforated disc of another vertical scaffolding element or scaffold post by means of the second wedge inserted through the opening thereof is fastened, that the frame member is pivotable in a horizontal plane relative to the projection.

According to a particularly preferred embodiment of the invention can be provided that the paragraph is alternatively or additionally provided with a front insertion bevel. This may be provided with an inclined surface, which may extend obliquely forward and / or inward and upward starting from the horizontal heel slot surface. As a result, the attachment of the connection head with its horizontal slot radially or in the forward direction on the projection or the insertion of the projection in the horizontal slot of the connection head is further facilitated.

The aforementioned inclined surfaces may individually or in each case or in both cases one, preferably about 10 to 30 Degree, in particular about 20 degrees, have sufficient inclination angle to the horizontal or to the paragraph slot surface. Thereby, a further improvement in terms of the above advantages can be achieved.

releasable connection, so that the connection head in any direction and only after a Unlocking of the wedge is removable by a force acting on the wedge of the projection.

As a result, an assembly of the scaffolding component with its connection head on the vertical scaffold element or on the projection particularly safe and yet relatively easy and easy from a secure position or from a secured position of a mechanic by this fitter even if the fitter of this Position or position from his hand can no longer reach into the area of that perforated disc on which the scaffold component is to be plugged with its connection head. Using the method according to the invention, therefore, a secure prefabricating of the scaffold component, for example in the form of a leading railing, is comparatively simple and easily possible.

Preferably, in the locking position of the wedge, in which the terminal head is positively locked by means of the wedge with the projection, the terminal head can not be removed from the projection in any direction without prior unlocking of the wedge.

The scaffold component may, prior to attachment of its connection head to the projection - either starting from a preparation position of the wedge, in which this toward or on an outer surface of a permanently connected to the connection head component, for example, rod element, preferably scaffold tube, in particular round tube, the scaffold component is folded - or starting from a preparation position of the wedge, in which this is loosely inserted only through the upper wedge opening or loosely through the upper and lower wedge opening, about a longitudinal axis in the form of a crossing line at which the center plane of the slot and the Vertical plane, preferably the vertical center plane, in particular the vertical plane of symmetry of the connection head intersect and / or about a, preferably parallel to the center plane of the slot extending longitudinal axis of the scaffold member are rotated by an angle of up to about 180 degrees, so that the wedge due to gravity . held in particular on the provided in the region of the lower wedge end or on the lower wedge end captive, supported on inner support surfaces of the upper head part hanging down.

Subsequent to or before or instead of or instead of the above measure, the scaffold component, before its attachment to the connection head or by means of the connection head on the projection, with the connection head and with the slot ahead, can be tilted forward and down in a tilt position, in which - one or the longitudinal axis in the form of a crossing line, at which the center plane of the slot and the vertical plane of the connection head intersect and / or one or the longitudinal axis of the frame component - has or have an inclination angle to the horizontal and in which the wedge due to gravity, in particular on the provided in the region of the lower wedge end or on the lower wedge end captive, supported on inner support surfaces of the upper head part downwards.

Preferably, in the said inclined position of the scaffold component, the downward-hanging wedge can be supported with a front wedge edge on a front wall part of the upper head part pointing downwards in this position. As a result, a shake-proof starting position can be achieved.

Subsequently, while maintaining one of these or a corresponding inclination position and / or at a corresponding angle of inclination to the horizontal, the scaffold component can be rotated back or further about the longitudinal axis of the connection head and / or about the longitudinal axis of the scaffold component by an angle of approximately 180 degrees. so that thereby enters the wedge in an upper pivot position, in which protrudes upwards over the upper head part out standing wedge member forward of at least the upper head part.

It may be particularly advantageous if, during the movement of the wedge from the top pivot position backwards and downwards into the mounting position, one or more in the region of the lower wedge end or on the lower wedge end of the wedge captive on one or the wedge-leading edge or the wedge-leading edge adjacent to the wedge is guided down. As a result, jamming or catching of the lower wedge end can be avoided or eliminated be, which in turn can be ensured that the wedge starting from a upwardly and forwardly over the front end of the connection head or on the front abutment support surfaces projecting upper pivot position, with a pivoting of the upper wedge end to the rear, with certainty gets on the wedge support surfaces of the wedge support body, so that there is no blockage of the slot.

Unless otherwise stated, the direction "backwards" means a direction transversely, in particular radially, to the longitudinal axis of the vertical frame element, away from it or opposite to the slip-on direction, in which the connection head projects with its contact-supporting surfaces, with his slit on the projection is plugged.

In the FIGS. 1 to 4 in each case a section of a scaffold 40, which is also referred to as a modular scaffold, is shown. The framework 40 is composed of vertical stems 41. The stems 41 form vertical framework elements. Each stem 41 extends vertically along a substantially straight longitudinal axis 47, thus forming a substantially straight bar element 41. The stems 41 are made of metal, preferably of steel. However, the stems can also consist of light metal, in particular aluminum or aluminum alloys. The stems 41 are made of round tubes 46.

The round tubes 46 have a substantially cylindrical outer cross section substantially over their entire effective length. Each stem 41 has at one of its free ends, preferably at its upper end, a pipe connector. The outer diameter of the pipe connector is slightly smaller than the inner diameter of the handle tube at the other end facing away from the pipe connector 41, so that on the pipe connector of a handle 41, a further handle 41 can be plugged. In this way, the framework 40 can be constructed over several floors.

On the stems 41 are in the axial direction 42, ie in the direction of the longitudinal axes 47 of the stems 41, in a, preferably about 50 cm amount, spacing 43 spaced from each other several connecting elements in the form of rosettes or perforated discs 44, preferably by welding, attached to There scaffolding components 45 in the form of connection, holding and / or support elements, such as longitudinal latch 45, crossbar and / or diagonal to connect. The diagonals and the cross bars are not shown in the figures. On or at the crossbars scaffolding floors 269 can be attached. Several framework fields 270.1, 270.2 can be set up. An installer 265 may assemble a scaffold member 45 from a tamper-evident layer 266. In this case, a leading railing 267 in the form of a hip or back railing 268 can be realized.

The perforated discs 44 surround the stems 41 in full, but can only partially embrace the stems 41. The perforated discs 44 forming a projection extend transversely, ie in the transverse direction 118, to the longitudinal axis 47 of the stem 41 from the outer surface 54 of the stem 41 to the outside 52. The perforated discs 44 are provided with upper and lower Boundary surfaces 48, 49 designed, which are parallel to each other and substantially flat. Accordingly, the perforated disks 44 have a substantially constant perforated disk thickness 50. The perforated disc thickness 50 is preferably about 9 mm, in particular if the perforated disc 44 is made of steel. However, the perforated disc thickness 50 may also be slightly larger, for example, be about 10 mm, in particular if the perforated disc 44 made of light metal, for example aluminum. The boundary surfaces 48, 49 of the perforated disk 44 are formed parallel to an imaginary center plane 51 of the perforated disk 44, which intersects the perforated disk 44 in the vertical direction or in the thickness direction 42 at the level of half of the perforated disk thickness 50. Each perforated disc 44 extends in a direction 52 perpendicular to the longitudinal axis 47 of the stem 41 from the outer surface 54 of the stem 41 radially outward 52 away from it. Accordingly, the center plane 51 of the perforated disc 44 is normal to the longitudinal axis 47 of the stem. Each perforated disc 44 is provided in a conventional manner with a plurality of through-holes 55, which are also designated with openings 55. This means that each of these through-holes 55 is bounded in its entirety by laterally delimiting wall parts of the perforated disk 44 or by wall parts of the perforated disk 44. Each through-hole 55 extends in the vertical direction 42 between the upper boundary surface 48 formed on the upper side 57 of the perforated disc 44 and the lower boundary surface 49 on the underside 58 of the perforated disc 44. The through-holes 55 are in a known manner in equal circumferential angles 59 of 45 degrees spaced apart. In addition, in a likewise known manner small and large openings 55.1, 55.2 are provided which alternately in the circumferential direction 60 are arranged. The exact design of the perforated discs 44 results in particular from the FIGS. 21 to 25 , The perforated disks 44 are preferably made of steel, but may also consist of light metal, in particular of aluminum or aluminum alloys.

The scaffold 40 shown in the figures is constructed with scaffold components 45 in the form of longitudinal bars 45 and cross bars as well as diagonals, wherein only the longitudinal bars 45 are shown in the figures. These bars 45 are fully compatible with the previously known bars and thus fully compatible with the previous LAYHER Allround modular scaffolding system designed. This means that the latch 45 can be readily combined with the previous other scaffolding parts of this previous modular scaffold system.

The scaffold bars 45 have at their ends facing away from each other 56.1, 56.2 each have a connection head 61, by means of which the scaffold bar 45 can be attached to a respective associated perforated disc 44. For this purpose, each connection head 61 has a wedge 62, which is captively connected to the connection head 61, by means of which the respective connection head 61 is festkeilbar to an associated perforated disc 44. The connection heads 61 can be fastened to a rod element 53 of the framework crucible 45 as components produced separately. The scaffold bars 45 shown in the figures are made in several parts or from several parts, namely in each case from two connection heads 61 and from a rod element 53. As rod element 53, a round tube 78 made of metal, preferably of steel, is used in the embodiments shown. It is understood, however, that the invention is not limited to bar elements, in particular not to such bar elements limited. So can be used as rod elements instead of round tubes and other profiles, such as U-profiles. Instead of rod elements 53, the connection heads 61 can also be attached to other components. For example, a framework component 45 may also be a console with one or more connection heads.

In the exemplary embodiment, the round tube 78 is welded as usual with the respective connection head 61. However, it is understood that a connection head can also be attached to a component of the scaffold component in another way. It is also understood that a scaffolding component with at least one connection head can also be made in one piece.

Each connection head 61 has a contact part 63 and a connection part 64. The connection part 64 is fixed, preferably by welding, connected to the round tube 78. The plant part 63 has plant support surfaces 65.1, 65.2 having plant wall parts 63.1, 63.2 for abutment with the corresponding outer surfaces 54 of the stem 41. These plant support surfaces 65.1, 65.2 are, in a horizontal section parallel to viewed in the center plane 68 of the slot 67, rounded concave with a radius 69 corresponding to the outer radius 70 of the round tube 46 of the stem 41.

Each connection head 61 is delimited by side wall parts 71.1 to 71.4, which in the direction of the front 79 have a wedge-like manner to a center or to a central axis 91 tapered vertical outer surfaces 72.1 to 72.4. The vertical outer surfaces 72.1 to 72.4 include a wedge angle 73 preferably about 44 degrees or 45 degrees.

The abutment part 63 comprises an upper head part 74 and a lower head part 75. The upper head part 74 has an upper abutment support surface 65.1 of the abutment support surfaces 65.1, 65.2 for abutment with a corresponding upper outer surface 76.1 of one above the projection 44 extending stem portion 77.1 of the stem 41. The lower head part 75 has a lower bearing support surface 65.2 of the abutment support surfaces 65.1, 65.2 for abutment with a corresponding lower outer surface 76.2 of a below the projection 44 extending stem portion 77.2 of the stem 41.

The upper head part 74 has an upper wedge opening 80 and the lower head part 75 has a lower wedge opening 81, for the wedge 62 which can be inserted through the wedge openings 80, 81.

Between the upper head part 74 and the lower head part 75, there is a horizontal slot 67 open to the abutment support surfaces 65.1, 65.2, that is to say towards the front 79, and also to the vertical outer surfaces 72.1 to 72.4, that is to say on both sides, with the connection head 61 can be plugged onto the perforated disc 44 or plugged. The slot 67 extends in the rearward direction preferably to the connection part 64th

Between the upper wedge opening 80 and the lower wedge opening 81, a wedge receiving space 84, also referred to as a passage 84, for the wedge 62 is formed, which extends through the upper head part 80 and through the lower head part 81, crossing the slit 67. The wedge receiving space 84 and the passage 84 is forward 79 through the abutment wall portion 63.1 of the upper head portion 74 and the abutment wall portion 63.2 of the lower head portion 75, to the Sides through the side wall portions 71.1 to 71.4 of the upper and lower head portions 74, 75, and rearwardly through the terminal portion 64, and in the upper head portion 74 by a wedge support body 85 and by a wedge-pivot abutment 86th limited, which will be discussed in detail below. The passage 84 or the wedge receiving space 84 is in through-connection with an opening 82 in the connection part 64. This in turn is in through-connection with the interior 87 of the round tube 78.

When the connection head 61 is completely plugged with its slot 67 on the perforated disc 44 and when the wedge 62 is inserted through the passage 84 and through an opening 55.1 of the apertures 55.1, 55.2 of the perforated disc 41, so that the connection head 61 of the Gerüstriegels 45 with the Perforated disc 44 is positively locked in a locking position 88 of the wedge 62, the upper wedge opening 80 of the upper head portion 74 and the lower wedge opening 81 of the lower head portion 75 are approximately aligned with this opening 55.1.

The wedge 62 can be moved or pulled up from the perforated disk 44 through the passage 84 or through the wedge opening 55.1 up to over the upper boundary surface 48 of the perforated disk 44 for unlocking the interlocking disk 44 locked with the perforated disk 44, so that then the connection head 61 removable from the projection 44, that is separately handled separately.

The connection head 61 is designed symmetrically to an imaginary vertical plane of symmetry 90, which is formed perpendicular to the imaginary horizontal center plane 68 of the slot 67. The vertical plane of symmetry 90 contains the imaginary vertical central axis 91, in which the vertical planes 92.1, 92.2 spanned by the vertical outer surfaces 72.1 to 72.4 of the side wall parts 71.1 to 71.4 of the connection head 61 intersect in front of the connection head 61. In the exemplary embodiment shown, the vertical plane of symmetry 90 also contains the longitudinal axis 94 of the round tube 78 of the scaffold component 45 or scaffold crucible 45. If the connection head 61 is plugged onto the perforated disc 44 and is locked and clamped there by means of the wedge 62, the vertical axis contains Symmetrieebene 90, the longitudinal axis 47 of the vertical framework member 41 and stem 41. In the insertion portion 93 of the slot 67 of the connecting head 61 is designed with its upper head portion 74 and its lower head portion 75 symmetrical to the center plane 68 of the slot 67. Accordingly, the upper abutment support surface 65.1 of the upper head portion 74 and the lower abutment support surface 65.2 of the lower head portion 75 are formed symmetrically to the horizontal center plane 68 of the slot 67 and further, the upper abutment support surface 65.1 of upper head portion 74 and the lower bearing support surface 65.2 of the lower head part 75 of equal size.

The slot 67 has a front insertion portion 93 in which it is bounded above with upper slot surfaces 95.1, 95.2 of the upper head portion 74 and down with lower slot surfaces 96.1, 96.2 of the lower head portion 75, which are parallel to each other, preferably also parallel to the longitudinal axis 94th of the round tube 78, run. There, the slot 67, viewed in the vertical direction 42, a first slot height 98 and first slot width, the vertical distance between the upper slot surfaces 95.1, 95.2 of the upper head portion 74 and the lower slot surfaces 96.1, 96.2 of the lower head portion 75 in the insertion 93 corresponds. This distance 98 is preferably about 12 mm. The said slot surfaces 95.1, 95.2; 96.1, 96.2 extend on both sides of an imaginary, in the amount of half of the slot height 98 and the slot width extending horizontal center plane 68 of the slot 67th

The slot 67 is bounded rearwardly with vertically extending slot surfaces 102.1, 202.2 of a slot bottom 103.1, 103.2. In the region of the slot bottom 103.1, 103.2, or in a rear portion of the slot 67, in which upper slot surfaces 99.1, 99.2 of the slot 67 then when the connection head 61 with its slot 67 completely plugged onto the perforated disc 44 and there by means of through an opening 55.1 of the perforations 55.1, 55.2 of the perforated disc 44 inserted wedge 62 is locked, an outer edge web 97 of the perforated disc 44 are opposite, which is bounded radially inwardly 79 of said aperture 55.1 of the perforated disc 44, the upper head portion 74 of the connection head 61 a Paragraph 100. The shoulder 100 extends, in a direction perpendicular to the horizontal center plane 68 of the slot 67 extending in the longitudinal direction 101 of the upper wedge opening 80 extending, the upper wedge opening 80 passing through, preferably in the transverse center of the connection head 61 extending, imaginary, vertical sectional plane 106, downstream of the upper slot surfaces 95.1, 95.2 formed in the insertion portion 93, and delimits the slot 67 with an upper heel slot surface 107 downward.

Characterized in that the shoulder 100 in the region of perpendicular to the horizontal center plane 68 of the slot 67 formed in the longitudinal direction 101 of the upper wedge opening 80th extending, the upper wedge opening 80 passing through, preferably in the transverse center of the connection head 61 extending imaginary vertical plane 90, in particular the vertical plane of symmetry 90 of the symmetrically designed connection head 61 is arranged, can be a particularly advantageous combination with or integration in one, the slot 67 over the front, above the slot 67 arranged wedge support body 85 realize. The wedge support body 85 has wedge support surfaces 108 for vertically supporting the lower wedge end 109 of the wedge 62 against inadvertently moving the wedge 62 vertically downward, intersecting the slot 67, to attach the terminal head 61 to its slot 67 in FIG a substantially horizontal Aufsteckrichtung 107 radially on the projection 44 and on the perforated disc 44 without blocking by the wedge 62 to allow.

The shoulder 100, containing said vertical plane 90, is formed on both sides of the vertical plane 90 and extends continuously between the upper side wall parts 71.1, 71.2. This can achieve a further improvement in terms of the above advantages, with a simple and easy plugging or pushing the connection head 61 with its slot 67 on the projection 44 is possible. The last-mentioned measure also makes it possible to achieve stiffening, in particular of the upper head part 74, of the connection head 61, so that the static characteristic values of the connection can be improved overall.

The shoulder 100 defines the slot 67 with the upper heel slot area 107. The upper heel slot area 107 is parallel to the upper slot areas 95.1, 95.2; 991., 99.2 and formed to the lower slot surfaces 96.1, 96.2 of the slot 67 and parallel to the horizontal center plane 68 of the slot 67. Between the upper shoulder slot surface 107 of the shoulder 100 and the lower slot surfaces 96.1, 96.2 of the slot 67, viewed in the vertical direction, the slot width 106 or height of the slot 67 is reduced due to the shoulder 44 to a vertical distance 106 which is smaller is as the distance 98 between the upper slot surfaces 95.1, 95.2 and the lower slot surfaces 96.1, 96.2 in the front insertion portion 93 of the slot 67, and thus is smaller than the slot width 98 or height of the slot 67 in this insertion 93. Der said distance 106 between the shoulder slot surface 107 and the lower slot surfaces 96.1, 96.2 in the exemplary embodiment is about 10.5 mm. About this paragraph 100, the connection head 61 then supports when it is completely plugged with its slot 67 on the perforated disc 44 and locked there by means of the wedge 62 on the upper boundary surface 48 of the outer edge web 97 of the perforated disc 44 in a support position vertically from.

Due to the said paragraph 100, the slot 67, viewed in the direction from front to back 52, designed in the direction of the slot bottom 103.1, 103.2 with a taper 111. The taper 111 or the shoulder 100 is formed with an upper wall portion 112 of the upper head portion 74. This upper wall part 112 extends horizontally and continuously between the side wall parts 71.1, 71.2 of the upper head part 74, preferably as shown in the figures. The said upper wall part 112 or the shoulder 100 is delimited to the front 79, ie in the direction of the insertion region 93 of the slot 67, with an oblique surface 113, which is inclined down and back. The oblique surface 113 extends, viewed in a vertical section containing the vertical plane of symmetry 90, from the upper slot surfaces 95.1, 95.2 of the insertion region 93 downwards 115 and rearward 52 towards the slot base 103.1, 103.2.

The abutment wall part 63.1 of the upper head part 74 of the connection head 61 is designed starting from its front abutment support surfaces 65.1 towards the slot 67, with an upper insertion bevel 116 inclined towards the rear 52 and 115 at the bottom. The abutment wall part 63.2 of the lower head part 75 of the connection head 61 is designed starting from its front abutment support surfaces 65.2 toward the slot 67, with a lower insertion bevel 117 inclined towards the rear 52 and above 110. These two insertion bevels 116, 117 facilitate the attachment of the connection head 61 with its slot 67 on the perforated disc 44.

The upper insertion bevel 116 merges rearwardly into the upper slot surfaces 95.1, 95.2 in the insertion region 93. The lower insertion bevel 117 merges rearwardly into the lower slot surfaces 96.1, 96.2 in the insertion region 93. Because of the slot height 98 or width of the slot 67, which is comparatively large in the insertion area 93, the connection head 61 with its slot 67 can accordingly be easily pushed or pushed onto the perforated disc 44. Because of the obliquely inclined surface 113 of the shoulder 100, which is inclined towards the rear 52 and 115, the connection head 61, when already radially attached to the perforated disc 44 with the insertion region 93, can slide radially further from there to the perforated disc 44 ,

As in particular from the Figures 28 and 31 As can be seen, the shoulder 100 is offset relative to the vertical outer surfaces 72.1, 72.2 of the upper side wall parts 71.1, 71.2 in the inward direction, that is, in the interior 123 of the connection head 61. In this case, the shoulder 100 is opposite the upper slot surfaces 95.1, 95.2; 99.1, 99.2 of the upper side wall parts 71.1, 71.2 arranged offset inwards in the direction. The upper slot surfaces 95.1, 95.2; 99.1, 99.2 of the upper side wall parts 110 extend from the insertion area 93 to the rear 52 in the direction of the slot bottom 103.1, 103.2, laterally and outwardly past the shoulder 100, above the heel slot area 107 of the shoulder 100. Laterally of the shoulder 100, ie viewed in a direction perpendicular to the vertical plane of symmetry 90 away, the upper slot surfaces 99.1, 99.2 and the lower slot surfaces 96.1, 96.2 a vertical distance 98 to each other, which is the same size as the distance 98 of the upper slot surfaces 95.1, 95.2 and the lower slot surfaces 96.1, 96.2 in the insertion 93rd

By the above measures, individually or in any combination weight can be saved and it is easier plugging or pushing the connection head 61 in a direction 120 perpendicular to the transverse direction 118, ie laterally or tangentially to the projection 44 possible. This is particularly advantageous if it is not possible for a plugging or pushing the connection head 61 in the direction of radially forward 79 on the projection 44 and the perforated disc 44, for example, because there is no sufficient space available or because the scaffolding component 45 and the scaffold bar 45 already facing away from the connection head 61 away End 56.2, in particular by means of a second connection head 61 and a second wedge 62, is already fastened to a projection 44 or to a perforated disk 44 of another vertical structural element 41 by means of the second wedge 62 inserted through an opening 55.1 of the openings 55.1, 55.2 that the framework component 45 or the framework bar 45 can be pivoted in a horizontal plane 121 relative to the projection 44 or to the perforated disc 44. Such a mounting situation is in the Figures 1 and 2 indicated, will be discussed in more detail below. The thus designed connection head 61 is particularly simple and inexpensive to produce.

Like from the Figures 28 and 31 can be seen, the paragraph 100 extends between the upper side wall portions 71.1, 71.2 in the spanned by this or by their inner boundary surfaces 122.1, 122.2 interior 123 throughout. As a result, a simple and easy plugging or pushing on the connection head 61 with its slot 67 on the projection 44 is possible and it can be a stiffening, in particular of the upper head portion 74 of the connection head 61 reach, so that the static characteristics of the compound improve overall to let.

The upper heel slot surface 107 of the heel 100 extends, viewed in a vertical section parallel to the vertical plane of symmetry 90, in a vertical first slot surface spacing 125 below the upper slot surfaces 95.1, 95.2 of the slot 67 provided in the insertion region 93. when the connection head 61 is supported on the heel 100 on the upper boundary surface 48 of the edge web 97 of the perforated disc 44, the lower slot surfaces 96.1, 96.2 of the slot 67 extend in a vertical second slot surface distance 126 below the lower boundary surface 49 of the edge web 97 of the projection 44. According to the invention, the first slot area distance 125 is the same as the second slot area distance 126. Preferably, the first slot area distance 125 and the second slot area distance Distance 126 each about 1.5 mm. By this measure remains when plugging the connection head 61 with its slot 67 on the perforated disc 44 a certain or low game, which facilitates the plugging. By said measure or by the specific training of paragraph 100 but also achieved that when the connection head 61 is completely plugged with its slot 67 on the perforated disc 44, so that the connection head 61 on the paragraph 100 on the top 57 of the perforated disc 44 on the edge web 97 of the perforated disc 44 is supported, a mediation of the connection head 61 is achieved both relative to the horizontal center plane 68 of the slot 67 and relative to the horizontal center plane 51 of the perforated disc 44. In other words, according to the invention, it can be achieved or provided that not only the first distance 151.1 of the upper end 152 of the upper contact support surface 65.1 of the upper head part 74 from the horizontal center plane 68 of the slot 67 and the second distance 153.1 of the lower end 154 of the lower abutment support surface 65.2 of the lower head portion 75 from the horizontal center plane 68 of the slot 67 are equal, but that the first distance 151.2 of the upper end 152 of the upper abutment support surface 65.1 of the upper head portion 74 from the horizontal -Mittene 51 of the perforated disc 44 and the second distance 153.2 of the lower end 154 of the lower abutment support surface 65.2 of the lower head part 75 from the horizontal center plane 51 of the perforated disc 44 are equal.

This allows the same Hebelarmverhältnisse be achieved with positive bending stresses upwards as well as negative downward bending stresses and accordingly improved static characteristics of the connection or the connection node.

Both the first distance 151.1 of the upper end 152 of the upper abutment support surface 65.1 of the upper head part 74 from the horizontal center plane 68 of the slot 67 and the second distance 153.1 of the lower end 154 of the lower abutment support surface 65.2 of the lower head part 75th from the horizontal center plane 68 of the slot 67 is in the illustrated embodiment about 36 mm. Both the first distance 151.2 of the upper end 152 of the upper abutment support surface 65.1 of the upper head part 74 from the horizontal center plane 51 of the perforated disc 44 and the second distance 153.2 of the lower end 154 of the lower abutment support surface 65.2 of the lower head part 75th from the horizontal center plane 51 of the perforated disc 44 is in the illustrated embodiment about 36 mm.

The shoulder portion 112 of the upper head portion 74 containing the shoulder 100 extends horizontally and transversely between the upper side wall portions 71.1, 71.2 in the interior 123 of the connection head 61. The said wall portion 112 also extends forwardly into the wedge receiving space 84 while limiting it to the rear. Said wall part 112 has a front boundary edge 128 which, viewed in a vertical section containing the vertical plane or the vertical plane of symmetry 90, is convexly rounded. This front boundary edge 128 forms a release edge 128 for releasing the wedge, which will be discussed in more detail below.

The said wall portion 112 and the paragraph 100 containing body also forms an inner wedge support body 85 for vertically supporting the lower wedge end 109 of the wedge 62 in a mounting position 263, in which an attachment of the connection head 61 with its slot 67 on the perforated disc 44 is allowed without blockage by the wedge 62. The wedge support body 85 is disposed above the slot 67, the slot 67 to the front 79 across. The wedge support body 85 has wedge support surfaces 108 on which the wedge 62 can be supported with its lower wedge end 109 in said mounting position 263. The wedge support surfaces 108 are adjacent to a front boundary edge 128 of the heel 100 and the said wall portion 112 to the rear 52 and top 110 extending at. At least the wedge support surfaces 108 of the wedge support body 85 arranged in the region or adjacent to the said boundary edge 128 are arranged at a small vertical distance 129 above the heel slit surface 107. This distance 129 is less than half of the slot height 98 or -breite in the insertion portion 93 of the slot 67. The wedge support surfaces 108 are inclined toward the front boundary edge 128 of said wall portion 112 obliquely forward 79 and 115 below and are , viewed in a vertical section containing the vertical plane of symmetry 90, concave. In the embodiment shown, the wedge support surfaces 108 are viewed in the said vertical section, with an inner radius 130, preferably amounting to approximately 7 mm. This inner radius 130 is slightly larger than the outer radius 131, preferably about 6.25 mm, of the wedge end portion 201 supported on the wedge support surfaces 108 at the lower wedge end 109 of the wedge.

The said wedge support surfaces 108 define a receiving pocket 132 for receiving and supporting the wedge end portion 201 at the lower wedge end 109 of the wedge 62, which, as previously mentioned, is concavely rounded with said outer radius 131. Viewed in the vertical section containing the vertical plane of symmetry 90, the receiving pocket 132 has an inner contour 133 which extends in a circle over a circumferential angle 134, preferably of approximately 160 degrees. The inner contour 133 of the receiving pocket 132 corresponds to a likewise circular outer contour 135 of the wedge 62 at its lower wedge end 109. In the vertical plane containing the vertical plane 90 vertical view, the receiving pocket 132 down 115 and front 79 of the lower front boundary edge 128 of the wedge Support body 85 and paragraph 100 limited. The receiving pocket 132 is bounded at the top 110 and front 79 by an upper front boundary edge 124 of a wedge-pivot abutment 86, which preferably at the same time forms a wedge-loser-securing body which limits the wedge receiving space 84 to the rear 52. The wedge pivot abutment 86 is thus above the vertical support of the wedge 62 at its lower wedge end 109 enabling wedge support surfaces 108 of the wedge support body 85 is arranged.

On the wedge pivot abutment 86, when the wedge 62 is vertically supported on the wedge support surfaces 108 of the wedge support body 85, it can be applied in the region of its lower wedge end 109. Then, when the wedge 62 on the wedge support surfaces 108 of the wedge support body 85 supported vertically abuts the wedge pivot abutment 86, the wedge 62 is about the wedge pivot abutment 86 with his to the top 110 via the upper wedge opening 80 outwardly projecting wedge member 136 to the rear 52 and at the same time with its lower wedge end 109 forward 79 pivotally, to a release position in which the lower wedge end 109 due to gravity or due to the weight of the wedge 62 after Front 79 on the lower, front, also referred to as the release edge boundary edge 128 of the wedge support body 85 and the paragraph 100 of time, vertically down 115 slips, so that the lower wedge end 109 in or through the slot 67 and under intersection of the slot 67, until it enters or through the lower wedge opening 81.

The front boundary edge 124 of the wedge-pivot abutment 86 extends horizontally between the upper side wall portions 71.2, 71.2 of the upper head portion 74 on either side of the vertical plane of symmetry 90, preferably continuously. The front boundary edge 124 of the wedge-pivot abutment 86 bounds the upper wedge opening 80 to the rear 52. The wedge-pivot abutment 86, in which the vertical plane of symmetry 90 containing vertical section views, starting from its front boundary edge 124, vertically down 115 of an inner wall portion 139 bounding the receiving pocket 132 of the upper head portion 74 is limited and, starting from its boundary edge 124 upwards 110, bounded by an upper wall portion 140 extending horizontally from the upper head portion 74 to the upper abutment wall portion 63.1. The upper wall part 140 has a surface 138 which runs approximately parallel to the middle plane 68 of the slot 67 or approximately parallel to the longitudinal axis 94 of the round tube 78 of the framework component 45 or of the framework bar 45. This is, in which the vertical plane of symmetry 90 containing vertical section considered, at a small distance 137 below the Outside surface 155 of the round tube 78 arranged. Said surface 138 of the top wall portion 140 and the top of the wedge pivot abutment 86, respectively, have a vertical distance 156 from the heel slot area 107 of the heel 100. This is about 18.3 mm in the embodiment shown. The front boundary edge 124 of the wedge-pivot abutment 86 has a horizontal spacing 142 from the abutment annular surface 141 of the connection part 64. This is about 22 mm in the embodiment shown.

As in particular from the Figures 24 . 31 . 34 and 35 As can be seen, the receiving pocket 132 is bounded in the region of the transverse center containing the vertical plane of symmetry 90 on both sides of the vertical plane of symmetry 90, that is to say laterally, with two centering support tabs 143.1, 143.2. The centering support tabs 143.1, 143.2 have opposite centering support surfaces 144.1, 144.2 for the wedge 62. The wedge 62 is supported laterally between the centering support surfaces 144.1, 144.2 at its lower wedge end 109 when the wedge 62 at its lower wedge end 109 rests on the wedge support surfaces 144.1, 144.2 of the wedge support member. Body 85 is supported. Thereby, a lateral tilting of the wedge 62 passing through the upper wedge opening 80 relative to the vertical plane of symmetry 90 can be minimized, whereby the wedge 62 during the movement of the connection head 61 with its slot 67 in a substantially horizontal Aufsteckrichtung 105 forward 79, radially on the projection 44 and on the perforated disc 44 and also during the attachment of the connection head 61 with its slot 67 forward 79 radially on the projection 44 and on the perforated disc 44, a more precise and safer actuation and release of the wedge 62 achievable is. The centering support surfaces 144.1, 144.2 the centering support tabs 143.1, 143.2 extend in a horizontal distance 157 to each other. The distance 157 is about 10 mm in the embodiment. This distance 157 is slightly larger than the thickness 145 of the wedge 62. The thickness 145 of the wedge 62 is about 6 mm in the exemplary embodiment. The centering support tabs 143.1, 143.2 are arranged in an upper region 146 of the receiving pocket 132, ie in the region or in the vicinity of the wedge-pivot abutment 86. The centering support tabs 143.1, 143.2 extend forward 79 and bottom 115 in the wedge-receiving space 84. Both measures have been found to be particularly advantageous when the wedge 62 at its lower wedge end 109 at the wedge support surfaces 108 of the receiving pocket 132 and the wedge support body 85 is supported in order then to achieve a secure guidance of the wedge 62 in the region of its lower wedge end 109 until its release.

In the receiving pocket 132 opens, preferably substantially above the wedge support surfaces 108, a zinc outlet opening 147. This extends from the receiving pocket 132 obliquely to the rear 52 and bottom 115 at an inclination angle 136 to the vertical axis 148 bis into a cavity 149 of the terminal head 61 which is in through-connection to the opening 82 in the terminal part 64 of the terminal head 61. In the embodiment shown, the angle of inclination 136 is about 57 degrees. The zinc outlet opening 147 has an inner diameter 150. This is in the illustrated embodiment about 6 mm. The zinc outlet opening 147 opens into the receiving pocket 132 in a central region between the centering support surfaces 144.1, 144.2 of the centering support tabs 143.1, 143.2 and the wedge support surfaces 108 Case of galvanizing the connection head 61 the zinc drain well from the receiving pocket 132, so that it can come in this area to no disturbing zinc accumulation. It is understood, however, that instead of a central zinc outlet opening 147, at least two, in particular each side of the vertical plane of symmetry 90 arranged, opening into the receiving pocket 132 zinc outlet openings may be provided. These can be provided, for example, vertically below the centering support tabs 143 or in horizontally spaced edge regions of the upper side wall parts 71.1, 71.2.

Hereinafter, the wedge 62 will be described in more detail, in the FIG. 36 shown separately, in a mounting position:

• The wedge 62 is made of flat material, in particular steel. It has a substantially constant wedge thickness 145. This is about 6 mm in the embodiment. The wedge 62 has facing away from each other, parallel wedge side surfaces 161.1, 161.2. The wedge 62 is bounded at the rear 52 with a rear, first wedge front edge 162 and forward 79 with a front, second wedge front edge 163. The rear or first wedge front edge 162 is bounded by a vertical, rear, substantially flat contact surface 164, which runs parallel to a vertical axis 148 or the vertical axis 148. The front and second wedge front edges 163 respectively have a substantially planar upper contact surface 166 and a substantially flat lower contact surface 167 which is parallel to the upper contact surface 166. The upper contact surface 166 and the lower contact surface 167 of the front and second wedge front edge 163 facing forward 79 of the rear 52 facing rear contact surface 168 of the rear or first wedge front edge 162 away. The upper contact surface 166 extends obliquely downwardly 115 and rearwardly 52 along a first oblique axis 169. The first oblique axis 169 is inclined to the vertical axis 148 at an inclination angle 170. The lower contact surface 167 also extends obliquely downwardly 115 and rearwardly 52 along a second oblique axis 171. The second oblique axis 171 is inclined to the vertical axis 148 at an inclination angle 172 equal to the inclination angle 170 of the first oblique axis 169 with respect to FIG vertical axis 148. The respective inclination angle 170, 172 is in the embodiment shown about six degrees. The first oblique axis 169 or the upper contact surface 166 is formed offset from the second oblique axis 171 or the lower contact surface 167, by a certain contact surface distance or amount 173 to the rear 52 back. Said amount 173, by which the upper contact surface 166 is offset backwards relative to the lower contact surface 167, is, in the illustrated embodiment, viewed in a plane parallel to the wedge side surfaces 161.1, 161.2 and in a direction normal to the lower contact surface 167, or in an imaginary vertical plane containing the first oblique axis 169 and the second oblique axis 171 and in a direction perpendicular to the second oblique axis 171, is about 3.0 mm

In the area between the front, lower contact surface 167 and the front, upper contact surface 166 of the front and second wedge front edge 163, this is parallel to the vertical axis 148 and parallel to the vertical rear contact surface 168 of the rear or first vertical wedge leading edge 162 extending, vertical limited front face 174. This end face 174 extends vertically over a length 175. This is in the exemplary embodiment about 21.5 mm. The upper contact surface 166 is in a, preferably about 92.4 mm from the lower wedge end 109 amount, wedge part distance 176, up 110, preferably rounded, for example, about 10 mm, rounding radius 177 rounded, in a back 52 and top 110 at an inclination angle 178 inclined inclined support surface 179, which in turn up to 110 in a parallel to the vertical axis 148 extending vertical support surface 180 of the front and second wedge front edge 163 over. In this manner, a toe board fitting recess 181 extending vertically above said oblique support surface 179 is formed, which enables the reception of a toe board fitting, not shown in the figures, of a toe board. The toe board fitting can be supported on its vertical support surface 180 side facing laterally on this vertical support surface 180 of the front and second wedge front edge 163. It can be supported vertically downwards on or on the inclined support surface 179 of the front and second wedge front edge 163. On its side remote from the vertical support surface 180, the toe board fitting can be supported on a vertical outer surface 76. 1 of a vertical framework element, for example a handle 41, when the connection head 61 is plugged onto a projection, for example onto a perforated disc 44 of the vertical framework element 41 and locked by means of the wedge 62, preferably also braced, is (see Figures 21 and 24 ). The vertical support surface 180 extends vertically over a length 164 in the upward direction 110 to the upper wedge end 181. This length may preferably be about 40 mm. The vertical support surface goes with a Rounding radius 184, preferably of about 5 mm, in an upper turning surface 183 at the upper wedge end 181 or Einschlagende of the wedge 62 via. The upper wedge end 181 or Einschlagende is formed with a horizontal, perpendicular to the vertical axis 148 extending upper wedge edge 182. This is limited to the upper wedge wedge surface 183 for driving the wedge 62 with a hammer. The wedge-wedge surface 183 is in the region of its rear upper end 185, in particular with a, for example, also about 5 mm amounting radius 186, rounded, in an upper wedge-inclined surface 187 of a wedge-inclined edge 188 over. The wedge-oblique edge 188 is formed in a, preferably about 12 degrees to the vertical axis 148 amount, inclination angle 189 forward 79 and 115 inclined below. The wedge-inclined surface 187 extends obliquely down 115 and front 79 until it merges in a wedge-part distance 176 of the lower wedge end 109 in the vertical, rear contact surface 168 of the rear or first wedge-front edge 162. The wedge portion 190 bounded by the wedge inclined surface 187, the upper wedge wedge surface 183 and the vertical vertical support surface 180 extends when the connection head 61 with its slot 67 plugged onto the projection or the perforated disc 44 and in a or the locking position 88 is locked and clamped, over the upper head portion 74 of the connection head 61 vertically upwards 110 addition (see FIG. 24 ). The upper wedge part 190 has a maximum wedge part width 191 in the region of the upper wedge end 181. This is about 27 mm in the embodiment. It is chosen so large that the wedge 62 is handled separately when the connection head 61 or the connection head 61 having scaffold component 45 and when the wedge 62 not only through the upper wedge opening 80 but is also plugged through the lower wedge opening 81, certainly can not fall down through the lower wedge opening 81.

In the vertical region, where the rear contact surface 168 of the first and rear wedge front edges 162 and the front end surface 174 of the second and front wedge front edges 163 extend parallel to each other, the wedge has a wedge width 237. This is preferably about 17.8 mm. The vertical, rear contact surface 168 is in a, preferably slightly less than about 43 mm amount, distance 192 from the lower wedge end 109 in a forward 79 and 115 down inclined inclined surface 193 of a lower wedge-inclined edge 194 in a , preferably about 12 degrees, inclination angle 195 is formed to the vertical axis 148. The inclined surface 193 of the lower wedge-bevel edge 194 extends in a, preferably about 20.2 mm, distance 196 from the lower wedge end 109 in a direction parallel to the vertical axis 148 extending vertical surface 197 of the rear or first wedge front edge 163, 162nd above. There, the wedge 62 has a lower wedge width 198 between the vertical surfaces 197, 205 of the rear and the front wedge front edge 162, 163 running parallel thereto. This is in the exemplary embodiment about 11 mm. The said vertical surface 197 extends parallel to the vertical axis 148 over a length 199. This is in the exemplary embodiment about 10 mm. The vertical surface 197 goes down 115 in a, the lower wedge end 109 delimiting wedge-end surface 200 of a wedge-end portion 201 over. In this, a bore 160 for receiving a captive, here a rivet 203, attached. The wedge end surface 200 of the lower wedge end portion 201 is rounded with a radius 204 that is greater than half of the lower wedge width 198, in which the wedge 62 is bounded by the rear vertical surface 197 of the rear and first wedge front edge 162 and the front, parallel thereto vertical surface 205 of the front and second wedge front edge 163 , In a lower region in which the wedge end surface 200 defines the rear wedge end edge 162 rearwardly 52, the wedge end surface 200 rises slightly rearward 52 over said rearward vertical surface 197 such that There is an increase 206 formed there. The raised portion 206 bounded by the rounded wedge-end surface 200, the vertical surface 197 adjoining it vertically upward, and the inclined surface 193 adjoining it obliquely rearwardly 52 and above 110 delimit a bridging recess 207 to ensure that the wedge 62, when it is inserted through the upper wedge opening 80 and captively secured by means of the captive 203, after an upward pull or in an upwardly pulled state in which the captive 203 a further extraction of the wedge 62 prevents upward, in the course of a rearward 52 and below 115 pivoting until the abutment of the wedge 62 with its rear or first wedge front edge 162 in the region of the upper wedge end 181 on the outer surface 155 of a fixed to the connection part 64 of the connection head 61 connected rod element, here the round tube 78, can be folded over. In this way, an optimally space-saving accommodation of the wedge 62 for transport purposes is possible and the risk of entanglement with other scaffolding components is minimized.

The rounded wedge end surface 200 of the lower wedge end portion 201 goes into one, the front, second wedge end edge 163 associated portion, upward 110 tangentially in the front lower vertical surface 205 of the front and second wedge-front edge 163 via. This vertical surface 205 extends to a distance 208 from the lower wedge end 209. This distance 208 is about 19.5 mm in the embodiment. The said vertical surface 205 passes upward 110 into the lower, front contact surface 167 of the front and second wedge front edge 163, respectively, preferably at a distance 219 from the lower wedge end 109.

The wedge 62 is captively connected to the connection head 61. For this purpose, the wedge 62 in the region of its lower wedge end 109, here on the wedge-end part 201, a captive 203 in the form of a material thickening. As a captive a rivet 203 is provided in the embodiment. This has laterally over the flat wedge-side surfaces 161.1, 161.2 of the wedge 62 projecting rivet heads 209.1, 209.2. As a rivet 203 may be used, for example, a Flachrundniet or blind rivet. Preferably, the Flachrundniet can be riveted by machine, while the blind rivet can be preferably riveted by hand. The rivet heads 209.1, 209.2 span a maximum rivet head diameter 210 that is greater than the inside diameter of the receiving bore 202 provided at the lower wedge end 109 of the wedge 62. Preferably, the maximum rivet head diameter 210 is less than twice the rounding radius 204 is rounded with the lower wedge end portion 201 (see, for example, the Figures 25 and 36 ).

The rivet 203 projects with its rivet heads 209.1, 209.2 laterally in a rivet width 211 beyond the two wedge side surfaces 161.1, 161.2 of the wedge 62, which is greater than the slot width 114 of the upper wedge opening 80th Thus If the wedge 62 can not be pulled upwards out of the connection head 61, the wedge 62 can only contact at least one of its rivet heads 209.1, 209.2 against the inner boundary surfaces 212 of the wall parts delimiting the upper wedge opening 80, in particular of the upper horizontal wall part 213, the upper head portion 74 of the connection head 61 are pulled upwards.

The lower wedge opening 81 of the lower head part 75 is larger than the upper wedge opening 80 of the upper head part 74, and so large that the lower wedge end 109 with the rivet 203 fastened there can be inserted easily down 115 through the lower wedge opening 81.

The designed as a longitudinal slot 215 upper wedge opening 80 extends on either side of the vertical plane of symmetry 90 of the connection head 61. The longitudinal slot 215 has a slot width 114 which is only slightly larger than the thickness 145 of the wedge 62. The slot width 114 in the exemplary embodiment is about 7.2 mm.

The upper wedge opening 80 is limited towards the front 79 with a front wall portion 216 of the abutment wall portion 63.1 of the upper head portion 74. This front wall portion 216 is also part of the upper horizontal wall portion 213, which defines the upper head portion 74 upwardly 110 with a horizontal outer surface 217, which is formed parallel to the center plane 68 of the slot 67. Inwardly toward the wedge receiving space 84, the upper horizontal wall portion 213 is bounded by a horizontal inner surface 212 that is parallel to the horizontal outer surfaces 217. The horizontal wall portion 213 goes to the rear 52 in an oblique down 115 to the connection part 64 extending rear wall portion 220 via. This is limited with part-circular cylindrical outer surfaces 221. The horizontal inner surfaces 212 of the upper horizontal wall portion 213 go on both sides of the upper wedge opening 80 to the rear 52 in wedge-guide surfaces 222.1, 222.2 from 52 to 52 and obliquely downward 115 wedge-leading edge 223.1, 223.2 over. The respective wedge-leading edge 223.1, 223.2 is formed with wedge-guide surfaces 222.1, 222.2 extending approximately perpendicular to the vertical plane of symmetry 90. These limit the rear wall portion 220 forward 79 to the wedge receiving space 84 out. The wedge-guide edges 223.1, 223.2 or their wedge-guide surfaces 222.1, 222.2 go obliquely to the rear 52 and bottom 115 tangentially into the receiving pocket 132 and its inner surfaces over. The wedge-leading edges 223.1, 223.2 or the wedge-guide surfaces 222.1, 222.2 allow an advantageous guidance of the wedge 62 at or over the material thickening, here the rivet heads 209.1, 209.2, which are provided in the region of the lower wedge end 109 of the wedge 62. This will be discussed in more detail below.

The upper abutment wall portion 63. 1 of the upper head part 74 having the front upper abutment support surfaces 65. 1 is delimited towards the rear 52 and below 115 to the wedge receiving space 84 with an inner, substantially flat, upper wedge support surface 225. The upper wedge support surface 225 extends approximately from the upper horizontal outer surface 217 of the upper horizontal wall portion 213 of the upper head portion 74 toward the rearward 52 and 115 below in the first inclination angle 170 to one or the vertical axis 148th The upper wedge support surface 225 extends obliquely downwardly 115 to a certain height 226 above the upper slot surfaces 95.1, 95.2 in the insertion area 93. This height 226 is in the exemplary embodiment about 8 mm. Thus, the upper abutment wall portion 63.1 of the upper head portion 74 is bounded inwardly toward the wedge receiving space 84 beyond said height 226 with a preferably planar inner surface 227 extending parallel to the vertical axis 148. This allows the wedge 62 inserted through the upper and lower wedge openings 80, 81, in particular starting from the wedge 62 in FIG FIG. 24 shown locking position 88, particularly easily or unhindered up 100 pull over the projection or on the perforated disc 44.

The vertical axis 148 is defined by a substantially planar, vertical wedge support surface 229 having one, preferably each, aperture 55; 55.1, 55.2 of the openings 55; 55.1, 55.2 of the perforated disc 44 bounded radially outward 52, which extends from the upper boundary surface 48 to the lower boundary surface 49 of the perforated disc 44. This vertical axis 148, to which the longitudinal axis 47 of the handle 41 extends in parallel, corresponds in the erected state of the handle 41 or the assembly 230 including the wedge 62 with the wedge 62 for a frame 40 or a frame 40, ideally the perpendicular. It should be understood that the vertical axis 148 may be inclined at a certain angle of inclination within the scope of the practical lead-out deviations from the perpendicular.

The lower abutment wall portion 63.2 of the lower head portion 75 is toward the rear 52 and down 115 to the wedge receiving space 84 with an inner, substantially flat, lower Wedge support surface 231 limited. The lower wedge support surface 231 extends approximately from the front end 232 of the lower insertion portion 93.2 of the lower head portion 75 in the region of the lower insertion bevel 117, obliquely toward the rear 52 and bottom 115 in the second inclination angle 172 to the vertical axis 148th , In this case, the lower wedge support surface 231 extends approximately to a lower horizontal surface 218 of the lower horizontal wall portion 214 of the lower head portion 75, which limits the lower head portion 75 down 115. The first inclination angle 170 is the same as the second inclination angle 172. It is thus in the embodiment shown, as in the wedge 62, each also six degrees.

The upper horizontal wall portion 213 is bounded at the top 110 with an upper horizontal surface 217 and the lower horizontal wall portion 214 is bounded at the bottom 115 by a lower horizontal surface 218 extending parallel to each other and parallel to the median plane 68 of the slot 67 , The upper horizontal wall portion 213 and its upper horizontal surface 217 and also the lower horizontal wall portion 214 and its lower horizontal surface 218 have, in a vertical section containing the vertical plane or the vertical plane of symmetry 90, an equal length 213rd , 234 on. This is about 21 mm in the embodiment shown.

The first inclination angle 170 and the second inclination angle 172, and accordingly, the upper wedge support surface 225 and the lower wedge support surface 231 are parallel to each other. The upper wedge support surface 225 and the first oblique axis 169 is opposite to the lower wedge support surface 231 and the second oblique axis 171 by a certain wedge support surface distance 243 or amount 173 offset back formed back. This amount 243 or the wedge support surface distance 243 is equal to the contact surface distance 173 or the amount 173, by which the upper contact surface 166 of the wedge 62 with respect to the lower contact surface 167 of the wedge 62 back 52 back is offset.

The said amount 243, by which the upper wedge support surface 225 is arranged offset backwards relative to the lower wedge support surface 231, is considered in the embodiment shown, in a vertical section running through the vertical plane of symmetry 90, as well is considered in a direction normal to the lower wedge support surface 231, or is approximately 3.0 mm in an imaginary vertical plane containing the first oblique axis 189 and the second oblique axis 171 and viewed in a direction perpendicular to the second oblique axis 171.

In other words, both the wedge 62 at its front wedge edge 163 have at least two wedge steps 244.1, 244.2 with parallel contact surfaces 166, 167 offset parallel to the wedge side surfaces 161.1, 161.2 by a specific amount 173 for the connection head 61, as well as the connection head 61 at an inner edge 89.1, 89.2 of the abutment wall portion 63.1, 63.2 or at inner edges 89.1, 89.2 of its abutment wall portions 63.1, 63.2 or on an inner side 83 of the passage 84 at least two connection head stages 246.1, 246.2 with parallel to the vertical plane or to the vertical plane of symmetry 90 offset by the same amount 243, parallel wedge support surfaces 225, 231, which correspond to the contact surfaces 166, 167 of the wedge 62. It is understood that the wedge 62 and the connection head 61 may also have more than two such stages. It is important, however, that the contact surfaces of the wedge-steps are parallel to each other and that the wedge-supporting surfaces of the connection head stages are also parallel to each other, so that it can not turn the wedge when driving the wedge.

The connection part 64 of the connection head 61 is bounded at the rear 52 with a fully continuous abutment-ring surface 141 which is perpendicular to the vertical plane of symmetry 90 and perpendicular to the central plane 68 of the slot or perpendicular to the longitudinal axis 94 of the rod member 78th or the round tube 78 is formed. The abutment annular surface 141 is perpendicularly intersected with respect to a line of intersection in which the vertical plane of symmetry 90 and the median plane 68 of the slot 67 cross perpendicularly with respect to the longitudinal axis 94 of the rod member 78 by an outer diameter 247, which is slightly smaller than the outer diameter 235 of the rod member 78 in the terminal region. This results in advantageous automatic welding conditions.

The abutment ring surface 141 is perpendicularly intersected with respect to the line of intersection in which the vertical plane of symmetry 90 and the median plane 68 of the slot cross inwardly in a radial direction with respect to the longitudinal axis 94 of the rod member 78 Inner diameter 248 limited. This is slightly smaller than the inner diameter 249 of the rod member 78 in the connection area.

Towards the rear 52 beyond the abutment annular surface 141, three centering tabs 250 extend into the Bar element or in the round tube 78 can be inserted or plugged there. The centering tabs 250 are arranged offset in each case in the same circumferential angles 251 of 120 degrees to each other about said cutting line or about the longitudinal axis 94 to each other. As a result, advantageous centering relationships between rod element 78 and connection head 61 result in a further reduced weight compared with the previous connection heads or frame components containing them.

The abutment ring surface 141 has, viewed from the front abutment support surfaces 65.1, 65.2 of the upper and lower abutment wall portion 63.1, 63.2 of the connection head 61, in a longitudinal section containing the vertical plane and the vertical plane of symmetry 90, a Distance 252, which is the same size as the corresponding distance 252 of the previous connection heads of the LAYHER Allround scaffold system or corresponding scaffolding systems. This distance 252 is about 50 mm. The connection head 61 is therefore also designed to be optimized in compliance with the structural boundary conditions predetermined by the modular system. But not only all measures according to the invention relating to the connection head 61, but also all measures according to the invention relating to the wedge 62 are inventively optimized such that an integration or combinability with the existing scaffolding parts is readily possible.

An arrangement 230 according to the invention will now be described, in which the connection head 61 of the frame component 45 with its slot 67 is horizontally placed on the perforated disc 44 and in which the wedge 62 through the upper wedge opening 80, through an opening 55.1 of Openings 55.1, 55.2 of the perforated disc 44 and through the lower wedge opening 81 is inserted, so that the wedge 62 is in a locking position 88, in which the connection head 61 with the perforated disc 44 against removal of the connection head 61 of the perforated disc 44 in all conceivable Directions is positively locked and in which the connection head 61 is removable only after unlocking of the wedge 62 by a force acting on the wedge 62 force from the perforated disc 44. Such an arrangement 230 or mounting and fastening situation is particularly in the FIGS. 21 to 25 illustrated.

In the locking position 88 of the wedge 62 with the vertical, substantially flat contact surface 168 of its rear or first wedge front edge 162 is flat on the corresponding, the opening 55.1 of the perforated disc 44 to the rear 52 bounding substantially flat, parallel to the vertical axis 148 extending vertical wedge support surface 229 of the perforated disc 44 applied or applied. At the same time, the wedge 62 is flat with the substantially planar upper contact surface 166 of its front wedge leading edge 163 extending rearward 52 and lower 115 at the first inclination angle 170 to the vertical axis 148 along the first oblique axis 169 the corresponding, substantially flat, rearwardly facing, inner, upper wedge support surface 225 of the upper head portion 74 can be applied, which also faces rearward 52 and below 115 at the first inclination angle 170 to the vertical axis 148 along the first inclined axis 169 extends. In addition, the wedge 62 is at the same time with the substantially flat, lower contact surface 167 of its front and second wedge front edge 163, which extend in the direction of rear 52 and bottom 115 in the second inclination angle 172 to the vertical axis 148 along the second oblique axis 171, flat against the corresponding, substantially flat, rearwardly facing 52, inner, lower wedge support surface 231 of the lower head portion 75 can be applied Also applied, which also extends in the rearward direction 52 and bottom 115 in the second inclination angle 172 to the vertical axis 148 along the second oblique axis 171.

In a different representation of the arrangement according to the invention of a scaffold component 45 with a connection head 61 and a vertical scaffold element 41 extending in the direction of a longitudinal axis 47, it can be transversely, ie in a transverse direction 118, away from the longitudinal axis 47 of the scaffold element 41, ie outwardly 52, extending projection 44 to be attached to the terminal head 61 is attached to form a releasable connection.

The projection 44 has an upper boundary surface 48 and a lower boundary surface 49. Preferably, these boundary surfaces 48, 49 extend on either side of a horizontal center plane 51 of the projection 44.

The projection 44 has at least one recess in the form of an opening 55; 55.1, 55.2 for inserting a wedge 62, which is arranged between a transversely 118 inner projection part 260 of the projection and a transversely outer projection part 97 of the protrusion 44 44 and extending between the upper and the lower boundary surface 48, 49 extends vertically.

The connection head 61 has an upper head part 74 with an upper wedge opening 80 and a lower head part 75 with a lower wedge opening 81, for the wedge 62 which can be inserted through the wedge openings 80, 81.

The connection head 61 has an abutment part 63, the contact wall parts 63.1, 63.2 having vertically extending abutment support surfaces 65.1, 65.2 for abutment with corresponding, vertically extending outer surfaces 54; 54.1, 54.2 of the vertical framework element.

The upper head part 74 has an upper abutment support surface 65.1 of the abutment surfaces 65.1, 65.2 for abutment with a corresponding upper outer surface 54.1 of a frame element part 241.1 of the vertical structural element 41 extending above the protrusion 44.

The lower head part 75 has a lower abutment support surface 65.2 of the abutment support surfaces 65.1, 65.2 for abutment with a corresponding lower outer surface 54.2 of a framework element part 241.2 of the vertical framework element 41 extending below the protrusion 44.

Between the upper head part 74 and the lower head part 75, a slot 67, which is open towards the abutment support surfaces 65.1, 65.2, is provided, with which the connection head 61 is attached to the projection 44.

The slot 67 is limited in a front insertion portion 93 of the slot 67 upwards 110 with upper slot surfaces 95.1, 95.2 of the upper head portion 74 and down 115 with lower slot surfaces 96.1, 96.2 of the lower head portion 75. Preferably, the slot surfaces 95.1, 95.2 extend; 96.1, 96.2 on both sides of a horizontal center plane 68 of the slot 67. The slot 67 is limited in the transverse direction 118 to the rear 52 with vertically extending slot surfaces 102.1, 102.2 of a slot bottom 103.1, 103.2.

Between the upper wedge opening 80 and the lower wedge opening 81 there is formed a passage 84, also referred to as a wedge receiving space, for the wedge 62 which extends through the upper head portion 74 and through the lower head portion 75 at the intersection of the slot 67 and with the recess 55; 55.1, 55.2 of the projection 44 is approximately aligned.

The wedge 62 is through the passage 84 and through the recess 55; 55.1, 55.2 of the projection 44 stretched, so that the connection head 61 of the frame member 45 is positively locked by means of the located in a locking position 88 wedge 62 with the projection 44.

The wedge 62 is movable to unlock the terminal head 61 from the projection 44 through the passage 84 upwardly 110 at least to over the upper boundary surface 48 of the projection 44, so that then the terminal head 61 is removable from the projection 44.

Either already when the wedge 62 is in the locking position 88 or when the wedge 62 is in the locking position 88 and the connection head 61 is braced by means of the wedge 62 with the vertical framework element 41, the upper head part 74 is supported by the upper abutment support surface 63.1 on the upper outer surface 54.1 of the framework element 41 and the lower head part 75 with the lower abutment support surface 63.2 on the lower outer surface 54.2 of the framework element 41 from.

The upper head portion 74 is seated with a limited by an upper slot surface 107 of the slot 67 support body 100 on the upper boundary surface 48 of the projection 44 in a support position.

Preferably, in the support position, the upper abutment support surface 65.1 extends vertically upwardly 110 to an upper end 152 which at a first distance 151.1 from the horizontal center plane 68 of the slot 67 and at a first distance 151.2 from the horizontal Middle plane 51 of the projection 44 is arranged.

Preferably, in the support position, the lower abutment support surface 63.2 extends vertically downwards 115 to a lower end 154, which at a second distance 153.1 from the horizontal center plane 68 of the slot 67 and at a second distance 153.2 from the horizontal Center plane 51 of the projection 44 is arranged.

The outer projection part 97 has a substantially flat, vertical wedge support surface 229, which the recess 55; 55.1, 55.2 in the transverse direction 118 outwardly 52 limited and which extends between the upper boundary surface 48 and the lower boundary surface 49 of the projection 44 parallel to or along or in the direction of a vertical axis 148.

The upper head part 74 can on a direction transverse to the longitudinal axis 47 of the vertical frame member 41 or stem, ie in the transverse direction 118 and radially inner side 236 of the Passage 84 and the wedge receiving space is a substantially flat, in the transverse direction 118 and radially outwardly 52 and facing backwards, outwards 52 and down 115 at a first angle of inclination 170 to the vertical axis 148 along a first inclined axis 169th having extending upper wedge support surface 225 for the wedge 62. The lower head part 75 may, on a transverse direction 118 or radially inner side 236 of the passage 84 or the wedge receiving space, be a substantially flat, in the transverse direction 118 or radially outward 52, in the outward direction 52 and in the bottom 115 in one second inclination angle 172 to the vertical axis 148 along a second oblique axis 171 extending lower wedge support surface 231 for the wedge 62 have. The upper wedge support surface 225 and the lower wedge support surface 231 are formed parallel to each other. The wedge 62 may further include a transversely 118 and radially outwardly 52, first wedge front edge 162 having a substantially planar, extending along the vertical axis 148 vertical contact surface 164, with the vertical wedge support surface 229th of the protrusion 44 corresponds such that the vertical contact surface 164 of the wedge 62 and the vertical wedge support surface 229 of the projection 44 are displaceable parallel to each other and lying flat against each other, relative to each other along the vertical axis 148. The wedge 62 may further include a second wedge leading edge 163 facing away from the first wedge leading edge 162, transversely 118 and radially inward 79, respectively, having a substantially planar upper contact surface 166 and a substantially planar parallel thereto , Lower contact surface 167 has. The upper contact surface 166 extends downwardly along the first oblique axis 169 115 and outwardly 52 and the lower contact surface 169 extends downwardly along the second sloping axis 171 115 and outwardly 52. The upper contact surface 166 of the second wedge front edge 163 corresponds to the upper wedge support surface 225 of the upper head part 74 such that the upper contact surface 166 of the wedge 62 and the upper wedge support surface 225 of the upper head part 74 are parallel adjacent to each other and flat against each other, relative to each other along the first inclined axis 169 are displaced. The lower contact surface 167 of the second wedge front edge 163 corresponds to the lower wedge support surface 231 of the lower head part 75 such that the lower contact surface 167 of the wedge 62 and the lower wedge support surface 231 of the lower head part 75 are parallel to each other and lying flat against each other, relative to each other along the second inclined axis 171 are displaceable.

As in particular in FIG. 25 can already be seen when the wedge 62 is in the locking position 88, the upper head portion 74 with the upper abutment support surface 65.1 at the above the perforated disc 44 extending outer surface 54.1 of the stem 41 and also the lower head part 75 can be supported with the lower abutment support surface 65.2 on the outer surface 54.2 of the stem 41 extending below the perforated disc 44. However, it is also within the scope of the inventive concept readily possible that only when the wedge 62 is in the locking position 88 and when the connection head 61 is braced by means of the wedge 62 with the vertical frame member 41, the upper head part 74 with the upper abutment support surface 65.1 at the outer surface 54.1 of the stem 41 extending beyond the perforated disc 44 and also the lower head portion 75 adjoin the lower abutment support surface 65.2 at the end below the perforated disc 44 extending outer surface 54.2 of the stem 41 are supported.

Starting from its locking position 88, for example, by a hammer blow from above on its EinschlagEnde 181, the wedge 62 with the perforated disc 44 and with the stem 41 can be braced. This causes a displacement of the wedge 62 relative to the perforated disc 44 on the one hand and a displacement of the wedge 62 relative to the connection head 61 on the other hand.

In this case, the vertical contact surface 168 of the rear or first wedge front edge 162 which slides on the corresponding vertical, parallel to the vertical axis 148 extending, the outer edge web 97 of the perforated disc 44 radially forward 79 and inwardly bounding wedge Support surface 229, which the opening 55; 55.1, 55.2 radially outwardly delimiting relative to the wedge support surface 229 in the direction 42 of the vertical axis 148 slidably relative to this wedge support surface 229 in the direction of the vertical axis 148 downwards.

At the same time, the inclined, upper contact surface 166, the front and second wedge front edge 163, which slides on the corresponding, parallel, oblique, inner, upper wedge support surface 225 of the upper abutment wall portion 63.1 relative to this in the direction of the first Slant axis 169 slidably abuts, relative to the upper wedge support surface 225 in the direction of the first inclined axis 169 downward.

Again at the same time slides the oblique, lower contact surface 167, the front and second wedge-front edge 163, at the corresponding, parallel, oblique, inner, lower Wedge support surface 231 of the lower abutment wall portion 63.2 slidably relative to this in the direction of the second oblique axis 171, relative to the lower wedge support surface 231 in the direction of the second oblique axis 171 downward.

When the wedge 62 is supported at its lower wedge end 109 on the wedge support surfaces 108 of the wedge support body 85, it protrudes with a wedge member 190 from the upper head portion 74 of the connection head 61 and then also with an upper wedge end 181 via the connection head 61 or via the front, vertical contact support surfaces 65.1, 65.2 forward or outward, such as in the FIGS. 9 to 20 shown. As also seen there, the wedge 62 in the mounting position 263, in which it is supported at its lower wedge end 109 on the wedge support surfaces 108 of the wedge support body 85 by its own weight or gravity, in the imaginary longitudinal center plane the wedge openings or in the imaginary vertical plane of symmetry 90 of the connection head 61 pivotable relative to the connection head 61, up to a forwardly inclined stop pivot position 261. In this stop pivot position 261, the wedge 62 is supported with its front or second wedge-front edge 163 at a the upper wedge opening 80 to the front 79 and radially inwardly bounding wall portion 216 of the upper abutment wall portion 63.1 and the upper horizontal wall portion 213 of the upper head portion 74 from.

• Bevor der Anschlusskopf 61 mit seinem Schlitz 67 in einer im Wesentlichen horizontalen und mit Bezug auf den Stiel 41 bzw. auf dessen Lochscheibe 44 radialen Aufsteckrichtung 105 bis auf die Lochscheibe 44 aufgesteckt wird, wird der Keil 62 in eine ein Aufstecken des Anschlusskopfes 61 mit seinem Schlitz 67 in der im Wesentlichen horizontalen Aufsteckrichtung 105 radial auf die Lochscheibe 44 ohne eine Blockade durch den Keil 62 ermöglichende Montagelage 263 überführt, in welcher der Keil 62 an seinem unteren Keilende 109 an den Keil-Stütz-Flächen 108 des Keil-Stütz-Körpers 85 abgestützt ist und in welcher der Keil 62 mit einem Keilteil 190 aus dem oberen Kopfteil 74 nach oben 110 heraus ragt und auch nach vorne 79 vor den Anschlusskopf 61, also vor den oberen Kopfteil 74 und den unteren Kopfteil 75 bzw. nach vorne 79 vor die vorderen, miteinander vertikal fluchtenden Anlage-Stütz-Flächen 65.1, 65.2, vorsteht. Eine derartige Ausgangssituation bzw. Ausgangsstellung ist in Figur 10 gezeigt.

The method according to the invention will be described below with reference to FIG FIGS. 1 to 25 shown embodiment, based on a scaffolding component or based on a connection head according to the first embodiment described in more detail, wherein the inventive method using a scaffold component or connection head and a wedge according to the second embodiment and according to the third embodiment, which will be discussed in more detail below, is executed or executed accordingly:

• Before the connection head 61 is plugged with its slot 67 in a substantially horizontal and with respect to the handle 41 or on the perforated disc 44 radial Aufsteckrichtung 105 to the perforated disc 44, the wedge 62 is in a plugging the connection head 61 with his Slit 67 in the substantially horizontal Aufsteckrichtung 105 radially transferred to the perforated disc 44 without a blockage by the wedge 62 enabling mounting position 263, in which the wedge 62 at its lower wedge end 109 at the wedge support surfaces 108 of the wedge support body 85 is supported and in which the wedge 62 protrudes with a wedge member 190 from the upper head portion 74 upwards out 110 and also forward 79 in front of the connection head 61, ie before the upper head part 74 and the lower head part 75 and 79 forward the front, mutually vertically aligned contact support surfaces 65.1, 65.2, projects. Such a starting situation or starting position is in FIG. 10 shown.

Based on this, the connection head 61, together with the wedge 62 located in the mounting position, is moved radially with its slot 67 in a substantially horizontal slip-on direction 105, approximately at the level of the perforated disk 44, until the wedge 44 62 in the region of its upper wedge end 181 with a wedge-front edge on the outer surface 54.1 of the upwards or above the perforated disc 44 extending upper stem portion 241.1 of the stem 41 abuts in a stop pivot position 261, such as in FIG. 11 shown.

The connection head 61 is then moved with its slot 67 further in a substantially horizontal Aufsteckrichtung 105, at the height of the perforated disc 44, radially forward 79 on the perforated disc 44, whereby at its lower wedge end 109 on the wedge support Body 85 vertically supporting and at the same time in the region of its upper wedge end 181 on the outer surface 54.1 of the stem fitting wedge 62 is pivoted with its upwardly projecting wedge member 190 relative to the connection head 61 to the rear 52.

At the same time or shortly after a continued movement of the connection head 61 with its slot 67 in a substantially horizontal Aufsteckrichtung 105, at the height of the perforated disc 44, radially forward 79 on the perforated disc 44 and on an opening 55.1 whose openings 55; 55.1, 55.2, then the wedge 62 is in the region of its lower wedge end 109 with a lower wedge end face 168.1 of its rear or first wedge front edge 162 on the wedge-pivot abutment 86 to which the wedge 62 then relatively is pivoted to the connection head 61 that its above the upper wedge opening 80 upwardly 110 outwardly projecting upper wedge member 190 is pivoted backwards and at the same time its lower wedge end 109 is pivoted forward 79. This will be a sequence according to the FIGS. 12 to 20 clearly, in which the connection head 61 with its slot 67 continued in a substantially horizontal Aufsteckrichtung 105, at the height of the perforated disc 44, radially forward 79 on the perforated disc 44 and an opening 55.1 whose openings 55; 55.1, 55.2 moves to ( FIGS. 12 to 14 ) and finally pushed radially on the perforated disc 44 ( FIGS. 15 to 20 ).

Like also from the FIGS. 12 to 20 can be seen, the wedge 62 remains supported during this continued horizontal movement of the connection head 61 relative to the perforated disc 44 at least as long as the wedge support surfaces 108 of the wedge support body 85 in the mounting position or in a functionally corresponding mounting position until a Aufsteck-limit position 262 is reached, from which the wedge 62 with a continued sliding of the connection head 61 with its slot 67 in a substantially horizontal Aufsteckrichtung 105 radially on the perforated disc 44 by gravity automatically down in said aperture 55.1 of the perforated disc 44 would reach. Such Aufsteck-limit position 262 is in the FIG. 20 reached.

In order to achieve an automatic locking of the connection head 61 with the perforated disc 44 by means of the wedge 62, the connection head 61 is pushed beyond the Aufsteck-limit position 262 addition radially forward 79 on the perforated disc 44, whereby or so that the wedge 62 due its continued pivoting about the wedge-pivot abutment 86, with its lower wedge end 109 or with the wedge-end part 201 there from the wedge-supporting surfaces 108 or the front, then acting as a release edge, boundary edge 128 of the wedge Support body 85 is released, whereupon the wedge 62 with its lower wedge end 109 by gravity automatically through the opening 55.1 of the perforated disc 44 and through the lower wedge opening 81 reaches into one or the locking position 88. In this locking position 88 of the connection head 61 is positively locked by means of the wedge 62 with the perforated disc 44 in such a way that the connection head 61 can be removed in any conceivable direction of the perforated disc 44, wherein the connection head 61 only after unlocking the wedge 62nd can be removed from the perforated disc 44 by a force acting on the wedge 62. In other words, the connection head 61 in the said locking position 88 of the wedge 62 can not be removed from the projection 44 without a prior unlocking of the wedge 62 by a force acting on the wedge 62.

It is understood that the wedge 62 for transferring it into the above-mentioned initial mounting position 263, starting from which the method according to the invention can be applied, manually by a person, for example by a fitter 265, by touching and moving by hand, into which said initial mounting position 263 can be transferred before the connection head 61 or the framework component 45 with its connection head 61 is fastened to a perforated disc 44 using the method according to the invention.

If it is the scaffold component 45, as in the FIGS. 1 to 4 shown, is a comparatively long rod element, in particular a longitudinal latch 45, which is to be mounted by the fitter 265 from a secured against falling layer 266, for example, as a leading railing 267, the fitter 265 would have to leave the secured position 266, for example, on a scaffold floor 269 of a scaffolding field already secured with a railing 268 270.1, the wedge 62 manually by touching and moving with one hand in its mounting position 263 convict and would then holding the scaffold bar 45 in the hands, the scaffold bar 45 with the affected connection head 61 ahead, toward a perforated disc 44 of the handle 41st of an adjacent scaffolding field lead to this perforated disc 44, which is located at a horizontal distance from the fitter, which is greater than the maximum grip or arm length of the 265 in the secured position 266 installer in the required for this manual Nachvornesetzen of Gerüstriegels 45 with the hands, it could, however, due to the required hand or handle change to major shocks, whereby the wedge 62 may fall from its mounting position 263 due to gravity, under crossover of the slot 67 down, so that then the slot 67 for a Plugging on the perforated disc 44 would be blocked.

• Dabei kann man vorteilhaft von einer Ausgangslage 271 des Anschlusskopfes 61 bzw. des Gerüstbauteils 45 mit seinem Anschlusskopf 61 ausgehen, in welcher das Gerüstbauteil 45 mit seinem Anschlusskopf 61 nach vorne 79 und unten 115 in einer Neigungslage 272.1 und einem entsprechenden Neigungswinkel 273.1 zu der Horizontalen 274 geneigt ist und in welcher der Keil 62 über die im Bereich seines unteren Keilendes 109 vorgesehene Verliersicherung 203 gehalten, an inneren Stützflächen 212 des oberen Kopfteils 74 abgestützt, schwerkraftbedingt bzw. aufgrund seines Eigengewichts nach unten hängt, und in welcher sich der Keil 62 mit seiner vorderen Keil-Stirnkante 163 an einer hinteren, die obere Keilöffnung 80 begrenzenden Kante 275 des oberen Anlage-Wandteils 63.1 bzw. des oberen Horizontal-Wandteils 213 des in dieser Stellung nach unten weisenden oberen Kopfteils 74 abstützt, beispielsweise wie in der Figur 7 gezeigt.

In order to avoid this, according to the invention, an alternative method can be used by means of which the wedge 62 can be transferred into its initial mounting position 263 without having to be touched by hand, at a time when the wedge 62 Installer 265, the scaffold component, here the scaffold bar 45, have already transferred with its connection head 61 in the direction of forward 79 in the vicinity of that perforated disc 44, to which the connection head 61 is to be fastened automatically locking by means of the wedge 62. From this position, the installer 265, holding the scaffolding component 45 in his hands, can then transfer the scaffolding component 45 into a substantially horizontal position at the level of the affected perforated disc 44, essentially without vibrations from which he can move the frame member 45 with its connection head 61 with its slot 67 substantially horizontally 105 and radially in the direction of said perforated disc 44. This alternative method is described below:

• In this case, one can advantageously proceed from a starting position 271 of the connection head 61 or the framework component 45 with its connection head 61, in which the framework component 45 with its connection head 61 forward 79 and below 115 in a tilt position 272.1 and a corresponding inclination angle 273.1 to the horizontal 274th is inclined and in which the wedge 62 held over the provided in the region of its lower wedge end 109 captive 203, supported on inner support surfaces 212 of the upper head portion 74, due to gravity or due to its own weight hanging down, and in which the wedge 62 with his front wedge-front edge 163 at a rear, the upper wedge opening 80 delimiting edge 275 of the upper abutment wall portion 63.1 and the upper horizontal wall portion 213 of this position downwardly facing upper head portion 74 is supported, for example as in the FIG. 7 shown.

Before this starting position 271 has been reached, it is possible, for example, to proceed from a preparation layer 276.1 of the connection head 61 or the framework component 45 with its connection head 61, in which the wedge 62 is folded in the direction of or onto the outer surface 155 of the round tube 78 of the framework crucible 45, such as in the FIG. 5 shown, or from an alternative preparation layer 276.2, in which the wedge 62 loose through the top and is inserted through the lower wedge opening 80, 81, such as in the FIG. 6 shown.

In particular, starting from one of these alternative preparation layers 276.1, 276.2, the scaffold component 45 or here the scaffold bar 45, about a longitudinal axis 159 in the form of a crossing line 159, at the center plane 68 of the slot 67 and the vertical plane, preferably the vertical center plane , in particular the vertical plane of symmetry 90, of the connection head 61 and / or about a, preferably parallel to the center plane 68 of the slot 67 extending longitudinal axis 94 of the rod member 94 and the frame member 45, rotated by an angle of up to about 180 degrees As a result, the wedge 62 is then held, due to gravity, via the captive securing device 203 provided in the region of the lower wedge end 109, suspended from inner support surfaces 225 of the upper head part 74 and hanging downwards. In this way, one can thus likewise reach the starting position 271 of the scaffolding component 45 or here of the scaffolding bar 45 already mentioned above.

Starting from such a starting position 271, then the scaffolding component 45, while maintaining a corresponding inclination position 272.1 or a corresponding inclination angle 273.1 about the longitudinal axis 159 of the connection head and / or about the longitudinal axis 94 of the scaffold component 45 back by an angle of about 180 degrees or further be rotated so that thereby enters the wedge 62 in an upper pivot position 253, in which its upper wedge member 190 upwardly 110 above and forward 79 projects in front of or above the upper head portion 74, such as in the FIG. 8 shown.

Subsequently, the frame member 45 is pivoted with its connection head 61 from said tilt position 272.1 in a less inclined slope position 272.2 with a reduced to at least equal to or less than twelve degrees inclination angle 273.2, possibly at least approximately in the horizontal 274, whereby the wedge 62 due to gravity due to its own weight from its upper pivoting position 253 (FIG. FIG. 8 ) comes down into a mounting position 263, in which it is supported on the wedge support surfaces 108 of the wedge support body 85 ( FIG. 9 ).

During the movement of the wedge 62 from its upper pivot position 253 (FIG. FIG. 8 ) to the rear 52 and bottom 115 in the mounting position 263 ( FIG. 9 ), the wedge 62 via the provided in the region of its lower wedge end 109 captive 203, here via at least one rivet head 209.1, 209.2 of the rivet heads 209.1, 209.2 of the rivet 203, on the previously mentioned wedge-leading edge 223.1, 223.2 or at the already abutting mentioned wedge-leading edges 223.1, 223.2 fitting, down tangentially into the receiving pocket 132 out.

Subsequently, the connection head 61 is moved forward with its slot 67, at the level of the perforated disk 44, radially forwards 79 in a substantially horizontal direction 105 to the perforated disk 44 until the wedge 62 in the region of its upper wedge end 181 on the outer surface 54.1 of Stiels 41 strikes, as from a comparison of Figures 10 and 11 seen. The further process sequence according to the invention has already been described above, so that reference may be made to these statements.

• Ein Monteur 265, der in einer durch einen als Rücken- bzw. Hüftgeländer 268 fungierenden Gerüstriegel 45 gegen Herabfallen gesicherten Lage 266 auf einem Gerüstboden 269 dieses Gerüstfelds 270.1 steht, kann den Gerüstriegel 45 in den Händen haltend, wie bereits vorstehend beschrieben, den Gerüstriegel 45 mit dem von dem Monteur 265 nach vorne 79 weg weisenden, vorderen Anschlusskopf 61 unter Anwendung des erfindungsgemäßen Verfahrens an der zugehörigen Lochscheibe 44 des von dem Monteur 265 entfernt aufgestellten Stiels 41 befestigen, so dass dort der besagte, vordere Anschlusskopf 61 mittels seines Keils 62 selbsttätig verriegelt wird, worauf dieser Keil 62 sich in seiner Verriegelungsstellung 88 befindet, in welcher der vordere Anschlusskopf 61 mit der Lochscheibe 44 des besagten Stiels 41 formschlüssig verriegelt ist. In dieser Verriegelungsstellung 88 ist der Keil 62 bislang aufgrund seines Eigengewichts nur lose durch die obere und durch die untere Keilöffnung 80, 81 eingesteckt, ist also noch nicht mit dieser Lochscheibe 44 bzw. mit diesem Stiel 41 verspannt. Dadurch bedingt und bedingt durch die Form bzw. Gestalt des Durchbruches 55.1 der Lochscheibe 44, durch den der Keil 62 in seiner Verriegelungsstellung 88 gesteckt ist, kann der an diesem vorderen Ende 56.1 verriegelte Gerüstriegel 45 mit seinem anderen bzw. hinteren Ende 56.2 bzw. mit seinem anderen Anschlusskopf 61 noch geringfügig seitlich in einer Horizontalebene verschwenkt werden, die im Wesentlichen parallel zu der Mittenebene 51 der Lochscheibe 44 verläuft bzw. diese Mittenebene 51 enthält. Deshalb kann der Monteur 265 den betroffenen Gerüstriegel 45 nicht nur, wie in der Figur 1 gezeigt, bereits von seitlich des in seiner Nähe befindlichen Stiels 41 mit dem vorderen Anschlusskopf 61 im Wesentlichen radial auf die entfernte Lochscheibe 44 aufstecken, sondern der Monteur 265 kann nach einem erfindungsgemäßen Befestigen des vorderen Anschlusskopfes 61 an dieser entfernten Lochscheibe 44, den Gerüstriegel 45, sofern dies noch nicht geschehen ist, nach unten 115 in die Horizontale 274 verschwenken, von wo aus der Monteur 265 den Gerüstriegel 45 mit seinem anderen Anschlusskopf 61 mit seinem Schlitz 67 seitlich bzw. tangential auf die in seiner Nähe befindliche andere Lochscheibe 44 aufstecken kann. Zu diesem Zwecke muss zuvor der Keil 62 dieses anderen Anschlusskopfes 61 nach hinten in Richtung auf die Außenfläche 155 des Stabelements 53 bzw. Rundrohrs 78 verschwenkt worden sein, damit dieser Keil 62 bei dem seitlichen bzw. tangentialen Einschwenken dieses Anschlusskopfes 61 auf die zugeordnete Lochscheibe 44 nicht mit dem Stiel 41 kollidiert, an dem diese Lochscheibe 44 befestigt ist.

If the framework member 45, here the scaffold 45, as in the FIGS. 1 to 4 shown, at its mutually facing away ends 56.1, 56.2 each have a connection head 61, 61, the attachment of the frame member 45 to the perforated discs 44, 44 of two adjacent stems 41, 41 can be performed as follows:

• A fitter 265 standing in a scaffold 45 protected against falling down by a scaffold 45 functioning as a back or hip rail 268 on a scaffold floor 269 of this scaffold 270.1 can hold the scaffold 45 in the hands, as already described above, the scaffold 45 attach the forward connection head 61 facing away from the installer 265 using the method according to the invention to the associated perforated disc 44 of the stalk 41 erected remotely by the installer 265, so that the said front connection head 61 automatically engages there by means of its wedge 62 is locked, whereupon this wedge 62 is in its locking position 88, in which the front connection head 61 is positively locked with the perforated disc 44 of said stem 41. In this locking position 88, the wedge 62 has so far only been loosely inserted through the upper and through the lower wedge opening 80, 81 due to its own weight, so it is not yet braced with this perforated disc 44 or with this handle 41. This conditional and due to the shape or shape of the opening 55.1 of the perforated disc 44, through which the wedge 62 is inserted in its locking position 88, the locked at this front end 56.1 Gerustriegel 45 with its other or rear end 56.2 or with his other connection head 61 are still slightly laterally pivoted in a horizontal plane, the substantially runs parallel to the center plane 51 of the perforated disc 44 and contains this center plane 51. Therefore, the installer 265 can not only the affected scaffold bar 45, as in the FIG. 1 shown already attached from the side of the nearby stem 41 with the front connection head 61 substantially radially on the removed perforated disc 44, but the fitter 265 may, after attaching the front connection head 61 according to the invention at this remote perforated disc 44, the scaffold bar 45, if this has not already been done, pivot down 115 into the horizontal 274, from where the installer 265 can attach the scaffold bar 45 with its other connection head 61 with its slot 67 laterally or tangentially to the other perforated disc 44 located in its vicinity. For this purpose, beforehand the wedge 62 of this other connection head 61 must have been pivoted rearwardly in the direction of the outer surface 155 of the rod element 53 or round tube 78, so that this wedge 62 in the lateral or tangential pivoting of this connection head 61 on the associated perforated disc 44th not collided with the stem 41, to which this perforated disc 44 is attached.

When the said other connection head 61 has been pushed with its slot 67 laterally or tangentially onto the associated perforated disc 44, a fastening situation is achieved, as in FIG. 2 is shown. Then, the fitter 265 can grasp the wedge of said other terminal head 61 by hand, as shown, and then swing the wedge 62 upwards by hand to a vertical pivotal position, from which the wedge 62, upon release, is gravitational its own weight or possibly after a hammer blow, down through the associated aperture 55.1 of this other perforated disc 44 into and through the lower wedge opening of this other connection head 61, also in a locking position 88 passes. Then the installer 265 can wedge this wedge 62 by means of a hammer blow from above onto its end of insertion 181, that is to say clamp it with the associated perforated disc 44 and with the associated handle 41. However, this may also be done later. This mounting situation in which the scaffold bar 45 mounted according to the invention or mounted as a leading railing 267 is positively connected to each of its two connection heads 61, 61 by means of the respective wedge 62, 62 in its respective locking position 88, 88 is locked in the FIG. 3 shown. If the scaffold bar 45 is positively locked in this way with its two connecting heads 61, 61 at least in the manner described above with the respective perforated disc 44, 44, the scaffold bar 45 is already so well secured that it is a sufficiently good for the fitter 265 Safety against lateral falling offers.

Therefore, the fitter 265 can then, as in FIG. 4 by way of example, now enter the adjacent scaffold floor 269 of the adjacent scaffold panel 270.2, which is secured against lateral falling by means of the scaffold as a leading hip or back railing 268 mounted and can from there the wedge 62 of the front connection head 61 and, if so has not yet happened, even the wedge 62 of the other terminal head 61 by means of a hammer beat wedged, so then in this way both connection heads 61, 61 by means of the respective wedge 62, 62 with the respectively associated Perforated disk 44, 44 and with the respectively associated handle 41, 41 are braced.

Subsequently, as likewise in the FIG. 4 FIG. 2 illustrates that the installer 265 has a further scaffold bar 45 as a knee bar 277 beneath the previously mounted or initially mounted scaffold bar 45 acting as a hip or back railing 268, at the perforated discs 44 arranged there at about half height above the scaffold floor 269 of the scaffold field 270. 44 fasten. For this purpose, the fitter 265, standing on the framework floor 269 of this framework field 270.2, attach this further scaffold bar 45 with its two connecting heads 61, 61 in each case laterally or tangentially to the respective associated perforated disc 44, 44. For this, as in FIG. 4 also shown, previously the wedges 62, 62 of these two connection heads 61, 61 in each case in the direction of the outer surface of the rod member or round tube 78 of Gerüstriegels 45 have been pivoted to the rear, so that there is no collision during lateral or tangential sliding of this Gerüstriegels 45 these wedges 62, 62 comes with the associated stems 41, 41. After the lateral or tangential sliding this Gerüstriegels 45 with its connection heads 61, 61 on the associated perforated discs 44, 44, the fitter 265, the wedges 62, 62 of these connection heads 61, 61 swing up manually and then release them, that then the wedges 62, 62 gravity or, if necessary, after a hammer blow from above on the Einschlagende 181 in their respective locking position 88, 88 move. Subsequently, the installer 265 wedges these wedges 62, 62, so that the scaffold bar 45 then mounted as a knee bar 277 is braced with the associated perforated discs 44, 44 and the associated stems 41, 41.

In the FIGS. 37 to 51 a second embodiment of an inventive arrangement 530 or a framework element 345 or a connection head 361 with an associated wedge 362 is shown. This arrangement 530 differs from that in the FIGS. 21 to 25 shown arrangement 230 solely in the design of the connection head and the wedge. Corresponding changed elements, parts and dimensions are in the FIGS. 37 to 51 provided with the reference numeral 300, while the same elements, parts and dimensions are provided with the same reference numerals. Accordingly, in the second embodiment, for example, the terminal head with the reference numeral 361 and the wedge with the reference numeral 362 are provided.

In the arrangement 530 according to the second embodiment, the scaffolding element or the scaffold post 41 with its at least one projection or with its at least one perforated disc 44 and the scaffold tube or rod element 53 are designed and formed the same, as in the arrangement 230 according to the first embodiment , It is understood, however, that these elements or components in the context of the invention individually or in combination may also be designed differently and / or formed.

• Bei dem in den Figuren 37 bis 50 gezeigten Anschlusskopf 361 gemäß dem zweiten Ausführungsbeispiel weist der obere Kopfteil 374 auf einer in Querrichtung 118 inneren Seite 383 der Passage 384 eine im Wesentlichen ebene, in Querrichtung 118 nach außen 52 weisende, sich parallel zu der vertikalen Achse 148 des vertikalen Gerüstelements 41 erstreckende, obere Keil-Stütz-Fläche 525 für den Keil 362 auf. Der untere Kopfteil 375 weist auf einer in Querrichtung 118 inneren Seite 383 der Passage 384 eine im Wesentlichen ebene, in Querrichtung 118 nach außen 52 weisende, sich parallel zu der vertikalen Achse 148 erstreckende, untere Keil-Stütz-Fläche 531 für den Keil 362 auf. Die obere Keil-Stütz-Fläche 525 und die untere Keil-Stütz-Fläche 531 sind parallel und ohne einen seitlichen Versatz zueinander bzw. miteinander fluchtend ausgebildet.

Hereinafter, the terminal head 361 with a matching wedge 362 according to the second embodiment with their differences from those in the FIGS. 3 to 15 shown connection head 61 and the matching, separately in FIG. 16 shown wedge 62 according to the first embodiment treated:

• In the in the Figures 37 to 50 according to the second exemplary embodiment, the upper head part 374 has, on a transverse side 118 inner side 383 of the passage 384, a substantially flat, transversely outwardly facing 52, parallel to the vertical axis 148 of the vertical framework element 41 Wedge support surface 525 for the wedge 362 on. The lower head portion 375 has, on a transverse side 118 inner side 383 of the passage 384, a substantially flat, in the transverse direction 118 outwardly 52 facing, parallel to the vertical axis 148 extending, lower wedge support surface 531 for the wedge 362 , The upper wedge support surface 525 and the lower wedge support surface 531 are formed in parallel and without lateral offset from each other.

The Indian FIG. 51 Wedge 362 according to the second embodiment shown separately in an installed position is similar in shape or shape to a wedge known from the prior art. The wedge 362 is also made of flat material, in particular steel. It has a substantially constant wedge thickness 445. This is about 6 mm in the embodiment. The wedge 362 has mutually facing, parallel wedge side surfaces 461.1, 461.2. The wedge 362 is bounded at the rear 52 with a rear, first wedge front edge 462 and forward 79 with a front, second wedge front edge 463. The rear or first wedge front edge 462 is bounded by a rear, substantially flat contact surface 468 which extends obliquely downwards 115 and front 79 at an inclination angle 470 to the vertical axis 148. The inclination angle 470 is in the embodiment shown about eight degrees, in particular 7.7 degrees. The front or second wedge front edge 463 has a substantially planar contact surface 466. The contact surface 466 of the front and second wedge leading edge 463 faces forward 79 away from the rearward facing 52 rear contact surface 468 of the rear and first wedge leading edge 462, respectively.

The vertical front contact surface 466 transitions upwardly 110 with a radius of curvature 484, preferably of about 5 mm, into an upper impact surface 483 at the upper wedge end 481 or impact end of the wedge 362, respectively. The upper wedge end 481 or Einschlagende is formed with a horizontal, perpendicular to the vertical axis 148 extending upper wedge edge 482. This is limited with the upper wedge wedge surface 483 for driving the wedge 362 with a hammer. The wedge-wedge surface 483 is in the region of its rear upper end 485, in particular with a, for example, also about 5 mm amounting radius 486, rounded, in the rear oblique contact surface 468 of the first wedge-front edge 462 over. The upper wedge portion 490 delimited by the inclined contact surface 468, the upper wedge wedge surface 483 and the vertical contact surface 466 extends when the terminal head 361 is slotted with its slot 67 onto the projection or perforated disc 44 and into one or more of them Locking position 388 is locked and clamped, over the upper head portion 374 of the connection head 361 vertically upward 110 addition (see, for example Figure 38 ). The upper wedge part 490 has a maximum wedge part width 491 in the region of the upper wedge end 481. This is chosen so large that the wedge 362 when the connection head 361 and the connection head 361 having scaffolding member 345 is handled separately and when the wedge 362 not only through the upper wedge opening 80 but also through the lower wedge opening 81 is inserted, certainly can not fall down through the lower wedge opening 81. The wedge 362 has a length of about 140 mm.

The vertical, rear contact surface 468 is in a, about 33 mm, distance 492 of the lower wedge end 409 in a forward 79 and down 115 inclined inclined surface 493, which at a, preferably about 13 degrees, inclination angle 495 to the vertical Axis 148 is formed. The inclined surface 493 merges at a distance 496, preferably approximately 20 mm, from the lower wedge end 409 into a vertical surface 497, running parallel to the vertical axis 148, of the rear or first wedge front edge 462. There, the wedge 362 has a lower wedge width 498 between the vertical surfaces 497, 505 running parallel thereto, the rear and the front wedge front edges 462 and 463. This is in the exemplary embodiment about 11 mm. The said vertical surface 497 extends parallel to the vertical axis 148 over a length 499. This is in the exemplary embodiment about 10 mm. The vertical surface 497 merges downwardly 115 into a wedge end surface 500 of a wedge end portion 501 bounding the lower wedge end 409. In this a bore 202 for receiving a captive, here a rivet 203, attached. The wedge end surface 500 of the lower wedge end portion 501 is rounded to a radius 504 greater than half of the lower wedge width 498 in which the wedge 362 extends from the rearward vertical surface 497 of the rear wedge end edge 462 and is bounded by the front, parallel thereto vertical surface 505 of the front and second wedge front edge 463. In a lower region, in which the wedge-end surface 500 the rear or first wedge front edge 462 bounded rearwardly 52, the wedge-end surface 500 rises slightly rearward 52 on the said rear vertical surface 497, so that there is a raised 506 is formed. The raised portion 506 bounded by the rounded wedge-end surface 500, the vertical surface 497 connected thereto vertically upward, and the inclined surface 493 adjoining it obliquely rearwardly 52 and above 110 delimit a bridging recess 507 to ensure that the wedge 362 when it is inserted through the upper wedge opening 80 and secured captively secured by the captive 203 with the connection head 361, after an upward pull or in an upwardly pulled state in which the Lashing 203 prevents further pulling out of the wedge 362 upward, in the course of a back 52 and down 115 pivoting until the abutment of the wedge 362 with its rear or first wedge front edge 462 in the region of the upper wedge end 481 on the outer surface 155 of a fixed with the connection part 364 of the connection head 361 connected rod element, preferably a round tube 78, easily can be transferred. In this way, an optimally space-saving accommodation of the wedge 362 for transport purposes is possible and the risk of entanglement with other scaffolding components is minimized. The rounded wedge end face 500 of the lower wedge end part 501 merges tangentially into the front contact face 466 of the front and second wedge end edge 463, respectively, in a portion associated with the front, second wedge leading edge 463.

The wedge 362 has a rearwardly or outwardly 52 facing rear edge or first wedge front edge 462, which has a substantially planar contact surface 468 extending obliquely outwards 52 and downwards 115 at an angle of inclination 470 to the vertical axis 148 along a sloping axis 469. The contact surface 468 of the first wedge-front edge 462 is located when the wedge 362 is in the locking position 388 and the terminal head 361 is braced by means of the wedge 362 with the vertical framework member 41, or when the wedge 362 in the locked position 388, only locally in the region of the upper recess edge 580 of an opening 55; 55.1 of the projection or the perforated disc 44 on the inward and forward facing 79 vertical wedge support surface 229 of the outer projection portion 97 at.

The wedge 62 furthermore has a front edge or second wedge end edge 463, which points in the transverse direction 118 forwards or inwards 79, and has a substantially planar vertical contact surface 366 extending parallel to the vertical axis 148 or rectilinearly. This contact surface 366 corresponds both to the upper wedge support surface 525 of the upper head part 374 and to the lower wedge support surface 531 of the lower head part 375 such that the vertical contact surface 366 of the wedge 362 and the vertical wedge support Surfaces 525, 531 of the connection head 361 parallel to each other and lying flat against each other, relative to each other along or in the direction of the vertical axis 148, are displaced.

Accordingly, the wedge 362 of the connection head 361, when the connection head 361 intended on a projection or on a perforated disc 44 of a vertical framework element or scaffold 41 is placed such that the wedge by the in the upper head part 374 and in the lower head portion 375 formed passage 384, crossing the slot 67 through an opening 55; 55.1 of the projection or the perforated disc 44 is inserted therethrough and is accordingly in a locking position 388, with its front, pointing in the direction of the vertical framework element or scaffold post 41, straight front edge 463 or with their contact surface 466 to the corresponding wedge support -Faces 525, 531 of the straight inner edges of the connection head 361, while the wedge 362 at the same time with its rear, away from the vertical frame member or the scaffolding stalk 41 away, oblique trailing edge 362 and their contact surface 468 point or horizontal line-line the vertically or vertically extending inner edge or its wedge support surface 229 of an opening 55; 55.1, 55.2. at the upper recess edge 280 of the projection or the perforated disc 44 abuts.

• Der Anschluss-Teil 364 des Anschlusskopfes 361 weist zwar ebenfalls drei Zentrierlappen 550.1, 550.2, 550.3 auf, jedoch erstrecken sich diese im Vergleich zu den Zentrierlappen 250 nunmehr jeweils über einen größeren Umfangswinkel. Dadurch wird insbesondere dann, wenn der Anschlusskopf, beispielsweise wie in dem bevorzugten Ausführungsbeispiel, aus Temperguss bzw. Hartguss hergestellt ist bzw. besteht, die Gefahr von Beschädigungen oder gar eines Abbrechens der Zentrierlappen 550.1, 550.2, 550.3 bei der Handhabung derselben bzw. bei einem Fallenlassen derselben, beispielsweise auf ein Transportband, minimiert.

Further differences of the connection head 361 with respect to the connection head 61 are briefly discussed below:

• Although the connection part 364 of the connection head 361 also has three centering tabs 550.1, 550.2, 550.3, these now extend in each case over a larger circumferential angle in comparison to the centering tabs 250. As a result, in particular when the connection head, for example, as in the preferred embodiment, is made of malleable or chilled cast iron, the risk of damage or even a breakage of Zentrierlappen 550.1, 550.2, 550.3 when handling the same or in a Dropping the same, for example, on a conveyor belt, minimized.

Furthermore, the Zentrierlappen 550.1, 550.2, 550.3 in the second embodiment shown now no longer designed the same and no longer offset in the same circumferential angles to each other. However, it is understood that such or similar centering tabs can be arranged in the same circumferential angles to each other. In the second embodiment shown, the two Zentrierlappen 550.1 and 550.3 are arranged offset in a circumferential angle 551.1 of about 180 degrees to each other. In contrast, viewed in the circumferential direction between the two Zentrierlappen 550.1 and 550.3 arranged further Zentrierlappen 550.2 to the adjacent Zentrierlappen 550.1, 550.3 each offset in a same circumferential angle 551.2 of only about 90 degrees ( FIG. 46 ). In this case, the said further centering tab 550.2 is assigned to the lower head part 375 of the connection head 361.

Further, the inclination angle 436 of the zinc spout 447 in the connection head 361 according to the second embodiment is increased from about 57 degrees to about 75 degrees to the inclination angle 136 of the zinc spout 447 in the connection head 361 according to the first embodiment. As a result, in accordance with the vertical section FIG. 18 formed or shown cross-sectional area of the wedge support body 385 increases accordingly. This in turn results in casting-technical advantages and also an overall greater carrying capacity of the connection head 361 in relation to the connection head 61.

As was the case with the connection head 61 according to the first exemplary embodiment, the slot 67 in the region of its slot bottom 103.1, 103.2 is also located below the connection head 361 according to the second exemplary embodiment in the insertion area 93; 93.1 formed horizontal upper slot surfaces 95.1 of the slot 67 extending paragraph 400 of the upper head portion 374 which is limited down 115 with a horizontal upper paragraph slot surface 107 of the slot 67 and the paragraph 400. Again, in the support position 281 above the horizontal upper boundary surface 48 of the outer projection portion 97 of the projection 44 arranged shoulder 400 is supported in the support position 281 and at least when the wedge 362 is in the locking position 388 and the connection head 361 with Help of the wedge 362 is clamped to the vertical frame member 41 or even when the wedge 362 is in the locking position 388, with its parallel to the horizontal upper boundary surface 49 of the projection 44 extending paragraph slot surface 107 on the upper boundary surface 48 of Projection or the perforated disc 44 from surface.

As was the case in paragraph 100 of the connection head 61, the shoulder 400 of the connection head 361 is delimited to the front 79, ie towards the insertion region 93 of the slot 67, with an oblique surface 113 of a front insertion bevel 282. This extends obliquely downwards 115 and rearward or outward 52 toward the slot bottom 103.1, 103.2 and merges in the outward or rearward direction 52 into the horizontal shoulder slot surface 107 of the shoulder 400. The inclined surface 113 includes with the horizontal 274 and the paragraph slot surface 107 a, preferably about 20 degrees amount, inclination angle 283 a.

Likewise, as in the paragraph 100 according to the first embodiment, are in the paragraph 400 in the area or Wedge support surfaces 108 of the wedge support body 385 disposed adjacent the front release edge 128 are disposed at a small vertical distance 429 above the heel slot surface 107. Here, too, the distance 429 is smaller than half the slot height 98 or width in the insertion region 93 of the slot 67. However, here the distance 429 is slightly larger than the distance 129, so that in this region of the shoulder 400 or of the wedge Support body 385 a greater accumulation of material or a greater material thickness is reached. As a result, correspondingly improved static characteristics of this connection head 361 can be achieved.

In contrast to the paragraph 100 according to the first embodiment, the paragraph 400 is additionally provided with lateral insertion bevels 585.1, 585.2. Each of these lateral chamfers 585.1, 585.2 is provided with an inclined surface 586.1, 586.2, which extends from the horizontal paragraph slot surface 107 of the paragraph 400 obliquely upward 110 and laterally to the respective vertical outer surface 72.1, 72.2 of the respective upper side wall portion 71.1, 71.2 out extends. The inclined surfaces 586.1, 586.2 include with the horizontal 274 or with the heel-slot surface 107 a, preferably about 20 degrees, inclining angle 587.1, 587.2 ( FIG. 48 ). This makes it easier to put on or push on the connection head 361 in a direction perpendicular to the vertical plane 90 or perpendicular to the transverse direction 118 and perpendicular to the vertical axis 148 or in the tangential direction onto the projection or perforated disk 44. This is particularly advantageous if, for a plugging or pushing the connection head 361 in the direction of forward 79 or in the radial direction on the Projection or on the perforated disc 44 is not possible, for example, because there is no sufficient space available or because the provided with the connection head 361 scaffolding component 45 already at its end facing away from the connection head 361 end 56.2, in particular by means of a second connection head 61 or 361 and a second wedge 62 or 362 is already attached to a projection or on a perforated disc 44 of another vertical scaffolding element or scaffold post 41 by means of the inserted through the opening 55 second wedge 62 or 362 such that the scaffold member 45 in a Horizontal plane relative to the projection 44 is pivotable.

For reasons of casting technology, both the upper horizontal wall part 513 of the connection head 361 with respect to the upper horizontal wall part 213 of the connection head 61 and the rear wall part 520 of the connection head 361 with respect to the rear wall part 220 of the connection head 361 were slightly changed in their design.

Further adjustments in the design and construction of the connection head 361 in comparison to the connection head 61 are due to the changed wedge 362 and its position in the passage 384. Thus, the upper abutment wall portion 363.1 and the lower abutment wall portion 363.2, in the example in FIG. 41 shown vertical cross section, now considered in the vertical direction 110, 115 constant or same thickness 588 on. The thickness 588 is preferably about 8.0 mm. Further, viewed in the same vertical cross-section, the outwardly 52-facing wedge support surfaces 525, 531 of both the upper abutment wall portion 363.1 of the upper head portion 374 and the lower abutment wall portion 363.2 of the lower head portion extend 375 now parallel to the two plant support surfaces 65.1 and 65.2.

For the rest, the two connection heads 61 and 361 differ, as can be seen from the figures, only in a few or minor details, which need not be discussed in greater detail here.

In the Figures 52 to 65 a third embodiment of an inventive arrangement 830 or a scaffold component or a connection head 661 is shown with an associated wedge 362. This arrangement 830 differs from that in the FIGS. 37 to 51 shown arrangement 530 according to the second embodiment exclusively in the design of the connection head. To the connection head 661 includes a wedge 362, as he already in connection with the second embodiment, in particular in FIG. 51 shown and described above. Corresponding changed elements, parts and dimensions are in the Figures 52 to 65 again provided with the reference number increased by 300, while the same elements, parts and dimensions are provided with the same reference numerals. Accordingly, in the third embodiment, for example, the terminal head is provided with the reference numeral 661 and the slot with the reference numeral 667.

Also in the arrangement 830 according to the third embodiment, the vertical scaffolding element or the scaffold stick 41 with its at least one projection or with its at least one perforated disc 44 and the scaffold tube or rod element 53 are designed and formed the same, as in the arrangement 230 and 530 according to the first and second embodiments. It is understood, however, that these elements or components within the scope of the invention, individually or in combination, also differently designed and / or can be formed. In the arrangement 830 or in the connection head 661 according to the third embodiment, an identical wedge 362 is provided as in the second embodiment (see FIG. 51 ), so that in this respect can be made to the above statements.

In contrast to both the first embodiment and the second embodiment, in the connection head 661 according to the third embodiment, the "paragraph" is omitted. In other words, there is in particular in the region of the slot bottom 103; 103.1, 103.2 no "paragraph" longer provided, but the slot 667 of the connection head 661 is, in the same or similar manner or design as known from the prior art connection heads, in particular the applicant, not only down 115 out with substantially flat, lower, horizontal slit surfaces 96.2 extending, starting from the lower end of the upper insertion portion 93.1 to the slot bottom 103; 103.1, 103.2, except transitional or transition regions, extend horizontally throughout, but the slot 667 is also bounded towards the top 110 with substantially upper horizontal slot surfaces 695.1, 695.2 extending from the lower end of the lower insertion portion 93.2 up to the Slot bottom 103; 103.1, 103.2, excluding transition radii or transitional areas, extending horizontally throughout. As a result, the connection head 661 is supported, when the connection head 661 is intended to be plugged onto the projection or the perforated disc 44 and when the wedge 362 is in the locking position 388 and the connection head 661 with the aid of the wedge 362 is braced with the vertical scaffolding or scaffolding handle 41 and / or, when the wedge 362 is in the locking position 388, with said horizontal upper slot surfaces 695.1, 695.2 of the slot 667 directly on the horizontal upper boundary surface 48 of the projection or the Perforated disk 44 flat.

In the third embodiment, the wedge support body 685 comprising the wedge support surfaces 108 is bounded at the bottom 115 by a substantially planar, horizontal, upper slot surface 695 of the slot 667 defined by the slot surfaces 695.1, 695.2 of FIG Schlitzes 667 spanned horizontal plane is arranged. The slot 667 is therefore delimited overall in the upward direction 110 by a substantially flat upper slot surface 695.1, 695.2. The wedge support body 685 continues to extend continuously between the upper side wall portions 71.1 and 71.2 of the connection head 661 and is integrally formed or connected to the side wall portions 71.1, 71.2. Moreover, the connection head 661 is the same or at least substantially the same design as the connection head 361 according to the second embodiment.

Characteristic both for the connection head 361 with associated wedge 362 according to the second embodiment and for the connection head 661 with associated wedge 362 according to the third embodiment, or for at least one such connection head 361 and 661, each with associated wedge 362 scaffolding component it is that this or this according to the inventive arrangement, in particular according to claims 1 to 9, is formed and that thus the method according to the invention, in particular according to claims 10 to 16, in the same way or according to executable. It is understood that the invention is not limited to the embodiments shown in the figures and described above, but that an inventive arrangement or a fastening method according to the invention in the context of the underlying in the claims and in the description of the invention also differently designed, dimensioned and / or can be designed or carried out. <B> LIST OF REFERENCES </ b> 40
