Description

The invention relates to a scaffolding component having at least one connection head for forming a detachable connection, in particular a connection node, with a vertical scaffolding element extending in the direction of a longitudinal axis, on which a transverse, ie in a transverse direction, extending to the longitudinal axis of the scaffold element and a recess is fastened in the form of an opening for insertion of a wedge-comprising projection, 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, for the plug-in by the wedge openings wedge, and wherein between the upper head part and lower head part a forwardly open slot for attaching the connection head, in particular in a substantially horizontal mounting direction, is arranged on the projection, and wherein the slot upwards and is delimited at the bottom with slit surfaces which extend on both sides of an imaginary horizontal center plane of the slot.

The invention also relates to a method for fastening a scaffold component having at least one connection head to a vertical scaffolding element extending in the direction of a longitudinal axis, on which a recess, in the form of an opening, extends transversely, ie in a transverse direction, to the longitudinal axis of the scaffold element By plugging one or the wedge exhibiting projection is fixed, wherein for forming a detachable connection, in particular a connection node, in which or in which the connection head is locked by means of a plug inserted through the recess form-fitting manner with the vertical framework element, the scaffolding component with the connection head is slipped or pushed with its slot or the connection head with its slot in a substantially horizontal Aufsteckrichtung on the projection of the vertical framework element.

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 portion is designed as a longitudinal slot with a slot width which is only slightly larger than the thickness of the inserted with its lower wedge end through 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 vertically above the perforated disc, so that subsequently the wedge, after its pivoting from said mounting position into a vertical insertion position, can move downwards due to gravity, either immediately through an opening of 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, to a slide-on position, in which the lower wedge end of the wedge in coincidence with an opening of the perforated ibe comes, the wedge can then move due to gravity through this opening and through the lower wedge opening into 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 occurring, the wedge can remain due to gravity and due to frictional forces in this forward pivoted position, provided that the frame 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 in practice in a part of these connection heads also possible, the wedge, when it is in such a forwardly pivoted position, with its lower and in this position rear wedge end on or on the upper wedge opening to the rear limiting, transverse to the mounting direction to support 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 would try to attach one of the known from the prior art connection heads with its wedge in a projecting forward or above the connection head projecting position on a perforated disc of a scaffolding handle in a practical manner, would after a contact of the wedge with its upper and in this position forward wedge end with the outer surface of the scaffold handle and with a continued moving the connection head with the thus forwardly projecting wedge in the radial direction of the scaffold to the wedge before the connection head has reached the perforated disc , Gravity fall with its lower wedge end down, with the result that the then fallen below crossing the horizontal slot down wedge plugging the connection head with its slot on the Block 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 scaffolding component with connection heads, which are designed the same or similar as disclosed in the above-mentioned publications, attached with their connection heads exclusively using a mounting method to the perforated discs, in which before attaching the connection head on the Perforated disk of the wedge, as described above, is first transferred to a rearwardly pivoted mounting position, and in which only then and in this mounting position of the wedge, the scaffold component with its connection head with its slot ahead, is slipped onto the perforated disc, and in which after attaching the connection head on the perforated disc, the fitter, in a limited by his personal grip or arm length maximum distance from the perforated disc, the wedge manually pivot 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 releasable wedge is provided, which is displaceable relative to the hook 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 a passage through the recess can move laterally into an expanded position, in which a vertical or vertical movement of the strut end is blocked upwards 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 walkable, which then by pushing the strut end in a horizontal direction to the stand For example, the wedge falls downwards due to gravity. 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 poses a significant security problem Moreover, 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.

It is an object of the invention to provide a scaffold component of the type mentioned above and a method for attaching a, preferably such, scaffolding component to a vertical scaffolding element, with or with 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 comparatively simple and easy, in particular from a secure position or secured position of a mechanic can be performed by this, in particular to allow a secured Vorbauen the scaffold component, such as a leading railing.

This object is achieved by the features of claim 1 and in a scaffolding component of the type mentioned in particular in that the connection head has a slot over the front slot above the slot arranged wedge support body with wedge support surfaces for vertical support of the Wedge in the region of its lower wedge end or at its lower wedge end - against unintentional movement of the wedge vertically down to a Blockadestellung, in which a, in particular complete, plugging the connection head with its slot in a substantially horizontal mounting direction, in particular radially on the protrusion would be blocked - or against unintentional movement of the wedge vertically downwards crossing the slot to a plugging the connection head with its slot in a substantially horizontal Aufsteckrichtung on the projection without blocking by the wedge to allow, and that the wedge when he, preferably in the region of its lower wedge end or with its lower wedge end, on the wedge support Supported surfaces of the wedge support body and projects with a wedge member up out of the upper head part, in an imaginary, perpendicular to the horizontal center plane of the slot, preferably in the transverse center of the connection head, extending vertical plane, in particular vertical plane of symmetry of symmetrical thereto designed to be pivotable relative to the connection head into a forwardly inclined stop pivot position, in which the wedge protrudes forwardly in front of the upper head part of the connection head or via this, and that the connection head above the vertical support of the wedge enabling wedge Support surfaces of the wedge support body a wedge-pivot abutment, on which the wedge, when it is supported on the wedge support surfaces of the wedge-support body, in the region of its lower wedge end can be applied or abuts and around which the wedge, when it on the Wedge-pivot abutment is applied, with its upwardly projecting beyond the upper wedge opening wedge member to the rear and at the same time with its lower wedge end is pivotable forward to achieve a release of the wedge so that the wedge by gravity and / or spring assisted automatically vertically down below the slot can reach into or through the lower wedge opening.

According to an advantageous embodiment of the invention, the wedge-supporting surfaces of the wedge-supporting body at a small vertical distance above the slot upwardly delimiting wall parts, in particular above horizontal slot edges or slot surfaces of the slot, be arranged. 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 above the slot upwardly bounding wall parts, in particular above the horizontal slot edges or slot surfaces arranged are smaller than half the slot height or half slot height and the slot width formed in the vertical direction.

It is also of great advantage if the wedge support body is arranged in the region of the slit rearwardly bounding vertical slot edges or surfaces of its slot bottom and / or in a rear portion of the 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 according to the invention can be adapted in a special way to the structural constraints of the modular system.

According to a particularly advantageous embodiment of the invention can be provided that the wedge-supporting body limits the 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 mounting position form-fitting and consequently against blurring and / or shaking be securely supported.

When the receiving pocket, viewed in the vertical direction, is formed between the wedge-pivot abutment and the 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 which is particularly advantageous under functional aspects 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, when the wedge is pulled out of the upper wedge opening sufficiently far upwards, it is completely turned back onto an outer surface of a wedge with the connection head firmly connected component of the scaffold component, in particular on a rod part or 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 extending horizontally at a height slightly below the level of the outer surface.

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 conditions can be achieved.

It may also be advantageous if the wedge support body and / or the wedge-pivot abutment are arranged in the interior of the connection head. This results in a particularly compact design. As a result, an embodiment of the connection head or of the scaffold component having it is possible, which makes it possible to perfectly meet the requirements for combinability or interchangeability of the scaffold component according to the invention with the previous scaffolding components.

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 transition mounting position against lateral tilting and correspondingly improved boundary conditions for actuating and releasing the wedge, can be achieved if the centering support surfaces below the upper wedge opening bounding wall parts of the upper head part 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. As a result, a jamming or entanglement of the lower wedge end can be avoided or avoided, whereby it can be ensured that the wedge, starting from an upwardly and forwardly over the front end of the connection head or on the front vertical bearing support surfaces projecting Swivel 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 advantageous development, the scaffold component according to the invention may be part of an arrangement with a vertical scaffolding element, to which a transversely extending projection is fastened, which has a recess in the form of an opening for the insertion of a wedge or the wedge, wherein the connection head by means of the plug-in by the recess of the projection wedge to form a releasable connection, in particular a connection node, with the projection positively lockable and with the vertical connection element is clamped, preferably wherein the connection head by means of the inserted through the recess wedge with the projection form-fitting to form the releasable connection, in particular of the connection node, is locked, wherein the wedge is in a locking position, preferably so that or wherein the connection head is not removable in any direction from the projection, in particular so that or wherein the connection head is removable from the projection only after a release of the wedge by a force acting on the wedge.

Accordingly, the invention may also relate to an arrangement of a scaffold component according to the invention with at least one connection head according to the invention and a vertical, preferably extending in the direction of a longitudinal axis, scaffold element to which a transversely extending projection is attached, which has a recess in the form of an opening for the passage of a Has wedge for positive locking and for clamping the connected to the vertical framework element or connected connection head of the scaffold component.

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 extends a second inclined axis, surface on a corresponding, lower, preferably substantially planar, rearwardly facing, in particular inner, wedge support surface of the lower head part can be applied, which also in the direction of backwards and downwards in the second inclination angle to the vertical axis along the second oblique axis or that the wedge in the locking position, at the latest when it is braced with the vertical frame member having a vertical, preferably substantially planar, contact surface of its rear wedge front edge flat against a corresponding, the recess of the projection to the rear limiting, preferably substantially flat, 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, which extends in a backward and downward direction at a first inclination angle to the vertical axis along a first oblique axis, flat on a corresponding, upper, preferably substantially flat, rearwardly facing, in particular inner, wedge Supporting surface of the upper head part, which also extends in the rearward and downward direction 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, which is in the direction of hi nten and below at a second angle of inclination 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 is also in Direction extends rearwardly and downwardly in 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 one, preferably in Has substantially flat, inwardly facing, vertical wedge support surface for the wedge, which limits the array, preferably in the transverse direction, outwardly and which between the upper boundary surface and the lower boundary surface of the projection parallel to or along or in the direction a vertical axis, and that the upper head portion on a transversely inner side of the passage a, preferably substantially flat, transversely outwardly extending, parallel to the vertical axis extending, vertical, upper wedge support surface for the wedge and in that the lower header has on a transversely inner side of the passage a preferably flat, transversely outwardly facing, vertical axis extending lower, vertical wedge support surface for the wedge, and that the wedge has a first wedge front edge, the one, preferably in Wese tliche level, obliquely in the direction of inwards and downwards at an inclination angle to the vertical axis along a sloping axis extending, outwardly facing 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 head portion 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, abutting, relative to both the vertical upper wedge support surface and the vertical lower wedge support surface, parallel to or along or in the vertical axis direction, is slidable.

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 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 slot with a downwardly formed in the insertion region for the projection horizontal upper slot surfaces of the slot extending paragraph of the upper head portion is bounded below with a horizontal upper shoulder slot surface of the slot, wherein the arranged in the support position above the horizontal upper boundary surface of the outer projection portion of the projection Paragraph in the support position and at least when the wedge is in the locked position and the connection head is braced by means of the wedge with the vertical frame member or even when the wedge is in the locking position, with its parallel to 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 plant 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, lateral forces can be better transmitted from the connection 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 slot and the projecting projection in this and the flat contact conditions of the inserted into the slot projection both downwards and upwards, the projection can be "taken along" in bending stresses both down and up well when that the connection head having scaffold component, such as a scaffold bar, is bent downwards or upwards, because the projection now both down and up advantageous can contribute to the bending in such a way that both downward and upward 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 can be provided that the horizontal center plane of the 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 which may extend obliquely upward and laterally from the horizontal shoulder slot surface towards the respective vertical outer surface of the respective upper side wall portion. 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 scaffolding component already provided with the connection head already has its end pointing away from the connection head, in particular by means of a second connection head or and a second wedge already is fixed to a projection or on a perforated disc of another vertical scaffolding element or scaffold post by means of the inserted through the opening of the second wedge such that the scaffold 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 have a, preferably about 10 to 30 degrees, in particular about 20 degrees, amounting inclination angle to the horizontal or to the paragraph slot surface. Thereby, a further improvement in terms of the above advantage can be achieved.

As a result, an assembly of the scaffold component with its connection head on the vertical scaffold element or on its projection particularly safe and yet relatively easy and easy, especially from a secure position or from a secured position of a mechanic by this mechanic even then possible if the fitter From this position or position with his hand can no longer reach into the area of that perforated disc on which the scaffolding component is to be plugged with its connection head. Thus, using the method according to the invention, a secured prefabrication of the scaffold component or of the scaffold component according to the invention, 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, preferably - either starting from a preparation position of the wedge, in which this towards 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, is folded - or starting from a preparation position of the wedge, in which this loose only by the upper wedge opening or loosely inserted through the upper and the lower wedge opening, about a longitudinal axis in the form of a crossing line at which the horizontal 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 horizontal 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, in particular over in the region of the lower wedge end or at the bottom Wedged intended captive held, 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 horizontal center plane of the slot and the vertical plane of the connection head intersect and / or one or the longitudinal axis of the scaffold 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 at the lower end of the wedge captive, supported on inner support surfaces of the upper head part hanging down.

In this way, an optimal intermediate position of the scaffold component can be achieved with its connection head with the wedge, starting from which the wedge is securely movable in its transition mounting position, in which it is supported on or on the wedge support surfaces, so that there can be no blockage through the wedge.

Subsequently, the scaffolding member may be pivoted with its connection head out of the said inclination position into a less inclined inclination position with a reduced inclination angle equal to or less than 12 degrees or equal to or less than seven degrees or equal to or less than five degrees, whereby the wedge by gravity and / or spring assisted from the upper pivot position down into the or a functionally equivalent or functionally identical mounting position passes, in which it is supported on the wedge support surfaces of the wedge support body. In this way, an optimal starting position of the scaffold component can be achieved with its connection head and its wedge, starting from which the Scaffolding member can be moved with its connection head with the slot and the protruding wedge ahead in this substantially horizontal direction on the projection, without causing a blockage of the slot through the wedge.

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 on. 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 fitted. 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. A fitter 265 may assemble a scaffolding member 45 of the present invention 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 formed with upper and lower boundary surfaces 48, 49 which are parallel to each other extending and substantially planar. 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, small and large openings 55.1, 55.2 are provided in a likewise known manner, which are arranged alternately in the circumferential direction 60. 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 scaffolding components 45 according to the invention in the form of longitudinal bars 45 and cross bars and 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 bars 45 according to the invention can readily be combined with the previous other framework parts of this previous modular scaffolding system.

The scaffold crucibles 45 according to the invention have, at their ends 56.1, 56.2 pointing away from each other, in each case a connection head 61 according to the invention, by means of which the scaffold crucible 45 can be fastened to an 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 limited to such rod elements. So can be used as rod elements instead of round tubes and other profiles, such as U-profiles. Instead of rod elements 53, the connecting heads 61 according to the invention can also be fastened to other components. By way of example, a framework component 45 according to the invention can also be a console with one or more connection heads according to the invention.

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 according to the invention can also be fastened in a different manner to a component of the scaffolding component according to the invention. It is also understood that a scaffold component according to the invention with at least one connection head according to the invention can also be produced 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 room 84 or 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 by the side wall portions 71.1 to 71.4 of the upper and the lower head portion 74, 75, and bounded rearwardly by the terminal member 64, as well as in the upper header 74 by a wedge support body 85 and by a wedge pivot abutment 86, which will be discussed in more 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 the 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, which corresponds to 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. 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 80 extending, the upper wedge opening 80 passing through, preferably in the transverse center of the connection head 61 extending, imaginary, vertical plane 90th , in particular the vertical plane of symmetry 90 of the symmetrically designed connection head 61, is arranged, a particularly advantageous combination with one or integration in one, the slot 67 to the front cross over above the slot 67 arranged wedge support body 85 can be realized. 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 downwardly intersecting the slot 67 to engage the terminal head 61 with 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 107 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 between the side wall parts 71.1, 71.2 of the upper head part 74, preferably, as shown in the figures, throughout. The said upper wall portion 112 and the shoulder 100 is limited to the front 79, ie in the direction of the insertion portion 93 of the slot 67, with an inclined surface 113 which is inclined downwards and backwards. 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. Due to the obliquely inclined surface 113 of the shoulder 100 at the bottom 52 and 115, the connection head can be located 61, when it is already plugged radially with the insertion area 93 on the perforated disc 44, from there slightly further forward to push 79 radially on 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 119 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, for a plugging or pushing the connection head 61 in the direction of radially forward 79 on the projection 44 or on the perforated disc 44 is not possible, for example, because there is no sufficient space available or because the scaffold component 45 and the scaffold bar 45 already at its end facing away from the connection head 61 end 56.2, in particular by means of a second connection head 61 and a second wedge 62nd , is already attached to a projection 44 or to a perforated disc 44 of another vertical structural element 41 by means of the inserted through an opening 55.1 of the apertures 55.1, 55.2 second wedge 62 such that the framework member 45 and the scaffold bar 45 in a horizontal plane 121 relative to the projection 44 and to the perforated disc 44 is pivotable. 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 provided in the insertion region 93. 95.2 of the slot 67. Then, when the terminal head 61 is supported on the heel 100 on the upper boundary surface 48 of the edge web 97 of the perforated disc 44, extend the lower slot surfaces 96.1, 96.2 of the slot 67 in a vertical second slot surface distance 126 below the According to the invention, the first slot area spacing 125 is the same size as the second slot area spacing 126. Preferably, the first slot area spacing 125 and the second slot area spacing 126 may each be approximately 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 -Mittenebene 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 the same size. 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 68 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. Said wall portion 112 also extends forwards into the wedge receiving space 123 while limiting it to the rear. Said wall part 112 has a front boundary edge 128 which, in one containing the vertical plane or the vertical plane of symmetry 90 Vertically sectioned, convex 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 the 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 smaller than half of the slot height 98 or width in the insertion portion 93 of the slot 67. The wedge support surfaces 108 are inclined towards the front boundary edge 128 of said wall portion 112 obliquely forward 79 and 115 below and are, in considered 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 is in the region of its lower Wedge 109 can be applied. Then, when the wedge 62 on the wedge support surfaces 108 of the wedge support body 85 is vertically abutted against the wedge pivot abutment 86, the wedge 62 is about the wedge pivot abutment 86 with its upward 110 over 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 forward 79 on the lower , Front, also referred to as the release edge boundary edge 128 of the wedge support body 85 and paragraph 100 of time, vertically down 115 slips so that the lower wedge end 109 in or through the slot 67 and at the intersection of the slot 67, to into or through the lower wedge opening 81 passes.

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 top wall portion 140 has an approximately parallel to the center plane 68 of the slot 67 and approximately parallel to the longitudinal axis 94 of the Circular tube 78 of the scaffold component 45 and the Gerürstriegels 45 extending surface 138 on. This is, viewed in the vertical symmetry plane 90 vertical section, viewed at a small distance 137 below the outer surface 155 of the round tube 78. 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 can be achieved. The centering support surfaces 144.1, 144.2 of 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 a central The area between the centering support surfaces 144.1, 144.2 of the centering support tabs 143.1, 143.2 and the wedge support surfaces 108 in the receiving pocket 132. By the above measures, in the case of zinc plating of the connection head 61, the zinc well out of Drain 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.

Below, the wedge 62 according to the invention will be described in more detail, which 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 edge 163 has a substantially flat, 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 respectively faces forward 79 away from the rearward facing 52 rear contact surface 168 of the rear and first wedge front edge 162. 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-front edge 162 extending, vertical front end face 174 limited. 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 facing away from the vertical support surface 180, the toe board fitting may be supported on a vertical outer surface 76.1 of a vertical structural element, for example a stem 41, when the connection head 61 is resting on a projection, for example on a perforated disc 44, of the vertical structural element 41 plugged 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 merges with a radius of curvature 184, preferably of about 5 mm, into an upper engagement surface 183 at the upper wedge end 181 or end of the wedge 62. 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 member 190 has in the region of the upper wedge end 181, a maximum wedge part width 191. 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 is inserted not only through the upper wedge opening 80 but also 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 approximately in the exemplary embodiment 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 to a radius 204 that is greater than half of the lower wedge width 198, in which the wedge 62 from the rear vertical surface 197 of the rear and first wedge front edge 162, respectively and is bounded by 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. 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. That way, one is optimal space-saving accommodation of the wedge 62 for transport purposes possible and the risk of entanglement with other scaffolding components is minimized.

The rounded wedge end face 200 of the lower wedge end part 201 merges tangentially into the front lower vertical face 205 of the front and second wedge front edge 163, respectively, in a portion associated with the front second wedge end edge 163. 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 Rounding radius 204 with which the lower wedge end portion 201 is rounded (see, for example, Figures 25 and 36 ).

The rivet 203 projects with its rivet heads 209.1, 209.2 laterally in a rivet width 211 on 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 80. Thus, the wedge 62 is not up 110th can be pulled out of the connection head 61, but the wedge 62 can only up to a stop at least one of its Nietköpfe 209.1, 209.2 on the inner boundary surfaces 212 of the upper wedge opening 80 bounding wall parts, in particular the upper horizontal wall portion 213, the upper head portion 74 of the connection head 61 are pulled up.

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, the upper head portion 74 bounded above 110 with a horizontal outer surface 217 which is formed parallel to the center plane 68 of the slot 67. Inwardly 123 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 obliquely downward 115 extending to the terminal part 64 rear wall portion 220 over. 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 portion 74 having the front upper abutment support surfaces 65.1 is towards the rear 52 and below 115 towards the wedge receiving space 84 with an inner substantially planar upper wedge support surface 225 limited. 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 downward 115 to a certain height 226 above the upper slot surfaces 95.1, 95.2 in the insertion region 93. This height 226 is about 8 mm in the exemplary embodiment. 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 is understood that the vertical axis 148 in the context of in practice resulting Aufstell- or suspension deviations from the vertical at a certain inclination angle can be inclined.

The lower abutment wall portion 63.2 of the lower head portion 75 is bounded toward the rear 52 and bottom 115 to the wedge receiving space 84 with an inner, substantially flat, lower wedge support surface 231. 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 or the first oblique axis 169 is offset from the lower wedge support surface 231 or the second oblique axis 171 offset by a certain wedge support surface distance 243 or amount 173 back to the rear , 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 on an inner edge 89.1, 89.2 of the abutment wall portion 63.1, 63.2 or on inner edges 89.1, 89.2 its abutment wall parts 63.1, 63.2 or on an inner side 83 of the passage 84 at least two connection head stages 246.1, 246.2 offset parallel to the vertical plane or to the vertical plane of symmetry 90 by the same amount 243, parallel wedge support surfaces 225th , 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 intersect with respect to the longitudinal axis 94 of the rod member 78, FIG radially inward direction is limited by an inner diameter 248. 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, there extend three centering tabs 250 which can be inserted into the rod element or into the round tube 78 or are inserted 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 according to the invention is thus also optimized in so far as it adheres to the design boundary conditions specified by the modular system. But not only all measures according to the invention relating to the connection head 61, but also all the measures according to the invention relating to the wedge 62 are inventively optimized in such a way that integration or combinability with the existing framework parts is readily possible.

An arrangement 230 according to the invention will now be described, in which the connection head 61 of the scaffold component 45 with its slot 67 is placed horizontally on the perforated disc 44 and in which the wedge 62 passes through the upper wedge opening 80, through an opening 55.1 of the perforations 55.1, 55.2 of the perforated disc 44 and is inserted through the lower wedge opening 81, so that the wedge 62 is in a locking position 88, in which the connection head 61 is positively locked with the perforated disc 44 against removal of the connection head 61 of the perforated disc 44 in all conceivable directions and in which the connection head 61 is removable from the perforated disc 44 only after unlocking the wedge 62 by a force acting on the wedge 62. Such an arrangement 230 or mounting and fastening situation is particularly in the Figures 21bis 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 52, inner, upper wedge support surface 225 of the upper head portion 74 can be applied or which also extends in the backward direction 52 and at the bottom 115 in the first inclination angle 170 to the vertical axis 148 along the first oblique axis 169. In addition, the wedge 62 is coincident with the substantially flat, lower contact surface 167 of its front and second wedge front edge 163, which are in the rearward direction 52 and bottom 115 at the second inclination angle 172 to the vertical axis 148 along the second oblique axis 171 extends, flat on the corresponding, substantially flat, rearwardly facing 52, inner, lower wedge support surface 231 of the lower head part 75 can be applied or applied, which also in the back 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 A wedge 62 which is disposed between a transversely 118 inner projection portion 260 of the projection and a transversely outer projection part 97 97 of the projection 44 and extending vertically between the upper and the lower boundary surface 48, 49.

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 in the locking position 88 is located and the connection head 61 is braced by means of the wedge 62 with the vertical frame member 41, the upper head portion 74 is supported with the upper abutment support surface 63.1 on the upper outer surface 54.1 of the framework member 41 and the lower head portion 75 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 is between the upper boundary surface 48 and the lower boundary surface 49 of the projection 44 extends parallel to or along or in the direction of a vertical axis 148.

The upper head part 74 may, in a direction transverse to the longitudinal axis 47 of the vertical framework element 41 or stem, ie in the transverse direction 118 or radially inner side 236 of the passage 84 or the wedge receiving space, be substantially planar, transversely 118 or radially, respectively 52 and rearwardly facing, in the outward direction 52 and bottom 115 at a first inclination angle 170 to the vertical axis 148 along a first axis 169 extending upper wedge support surface 225 for the wedge 62 have. 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 also be one away from the first wedge front edge 162, in the transverse direction 118 or radially inwardly facing, second wedge-front edge 163 163 having a substantially flat, upper contact surface 166 and a parallel, substantially flat, lower contact surface 167. The upper contact surface 166 extends down the first oblique axis 169 down 115 and out 52 and the lower contact surface 169 extends along the second oblique axis 171 down 115 and out52. 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 if the connection head 61 is braced by means of the wedge 62 with the vertical framework element 41, the upper head part 74 adjoins the upper abutment support surface 65.1 on the outer surface 54.1 of the stem 41 extending beyond the perforated disc 44 and also the lower head part 75 with the lower abutment support surface 65.2 on the extending below the perforated disc 44 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 Slanted axis 169 slidably abuts relative to the upper wedge support surface 225 in the direction of the first oblique axis 169 down.

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

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 one of 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.

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

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 to the perforated disc 44 without a blockade by the wedge 62 enabling mounting position 263 transferred, in which the wedge 62 supported at its lower wedge end 109 on the wedge support surfaces 108 of the wedge support body 85 is and in which the wedge 62 protrudes with a wedge member 190 from the upper head portion 74 upwards 110 out 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 forward 79 in front of the front , mutually vertically aligned abutment support surfaces 65.1, 65.2, protrudes. 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 abuts in the region of its upper wedge end 181 with a wedge front edge on the outer surface 54.1 of the upper stem part 241.1 of the stem 41 extending above or above the perforated disc 44 in a stop pivot position 261, such as in FIG 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 be over the upper wedge opening 80 outwardly 110 outwardly projecting upper wedge member 190 pivoted to the rear 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 on 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 during this continued horizontal movement of the connection head 61 relative to the orifice plate 44 at least as long still supported on 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 to 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 around the wedge-pivot abutment 86, with its lower wedge end 109 or with the there given wedge end portion 201 of the wedge support surfaces 108 and the front, then acting as a release edge, boundary edge 128 of the wedge support body 85 comes free, 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 into one or the locking position 88 passes. 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, standing on a scaffold floor 269 of a scaffolding field 270.1 already secured with a railing 268, manually transfer the wedge 62 into its mounting position 263 by touching and moving it with one hand, and then, holding the scaffold bar 45 in its hands, would have to place the scaffold bar 45 with the relevant connection head 61 ahead, lead in the direction of a perforated disc 44 of the stem 41 of an adjacent scaffolding field to this perforated disc 44, which is located at a horizontal distance from the fitter, which is greater than the maximum handle or arm length in the secured position 266 maintenance worker 265. In the case of the required manual Vorvornesetzen the Gerüstbar 45 with the hands, it could, however, due to the required hand or handle change come to greater shocks, whereby the wedge 62 may fall from its mounting position 263 gravitationally, under crossover of the slot 67 down, so that then the slot 67th would be blocked for an attachment to the perforated disc 44.

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 scaffolding component, here the scaffold bar 45, with Its connection head 61 may have already moved in the direction of the front 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 scaffold component 45 into a substantially horizontal position at the level of the affected perforated disc 44 substantially without vibrations, starting from which it carries the scaffold component 45 with its connection head 61 its slot 67 substantially horizontally 105 and radially in the direction of said perforated disc 44 to move. 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 is loosely inserted through the upper and 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 framework component 45 or here the framework bar 45, about a longitudinal axis 159 in the form of a crossing line 159, at which the horizontal center plane 68 of the slot 67 and the vertical plane, preferably the vertical -Mittenebene, in particular the vertical plane of symmetry 90, of the connection head 61 and / or a, preferably parallel to the horizontal center plane 68 of the slot 67 extending longitudinal axis 94 of the rod member 94 and the framework member 45, by an angle of up to be rotated about 180 degrees, so that as a result of the wedge 62 then by gravity held over the provided in the region of the lower wedge end 109 captive 203, supported on inner support surfaces 225 of the upper head portion 74 depends down. 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 scaffold member 45 while maintaining a corresponding inclination position 272.1 or a corresponding inclination angle 273.1 are rotated back or further about the longitudinal axis 159 of the connection head and / or about the longitudinal axis 94 of the framework component 45 by an angle of about 180 degrees, thereby passing the wedge 62 into an upper pivot position 253 in which its upper wedge portion 190 retards above 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 ) 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 with its slot 67 in front, at the level of the perforated disc 44, radially to the front 79th in a substantially horizontal direction 105 moves toward the perforated disc 44 until the wedge 62 abuts in the region of its upper wedge end 181 on the outer surface 54.1 of the stem 41, 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.

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 of the wedge 62 is so far only loose due to its own weight inserted through the upper and through the lower wedge opening 80, 81, so it is not yet this perforated disc 44 or braced with this stem 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 its other connection head 61 are still slightly laterally pivoted in a horizontal plane, which runs substantially parallel to the center plane 68 of the perforated disc 44 and contains this center plane 68. 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.

If the said other connection head 61 with its slot 67 laterally or tangentially to the associated perforated disc 44 has been postponed, a fixing 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 his own weight or possibly after a hammer blow, down through the associated opening 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 field 270.2, the device 90 mounted by means of the pre-built as leading hip or back railing 268 is secured against lateral falling down and can from there the wedge 62 of the front connection head 61 and, if not already done, also the wedge 62 of the other connection head 61st by means of a hammer beat, so that in this way both connection heads 61, 61 are clamped by means of the respective wedge 62, 62 with the respective associated perforated disc 44, 44 and with the respective associated handle 41, 41.

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 of this Gerüstriegels 45 with its connection heads 61, 61 on the associated perforated discs 44, 44, the installer 265, the wedges 62, 62 of these connection heads 61, 61st manually swing up and then release them, that then move the wedges 62, 62 due to gravity or, if necessary, after a hammer blow from above on the Einschlagende 181 in their respective locking position 88, 88. 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 shows a second embodiment of an inventive arrangement 530 or a scaffold element 345 according to the invention or a connection head 361 according to the invention with an associated wedge 362. 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.

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 to the rear 52 with a rear, first Wedge-front edge 462 and front 79 limited 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 and second wedge front edge 463 has a substantially flat 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 or the connection head 361 having scaffolding member 345 is handled separately and when the wedge 362 is inserted not only through the upper wedge opening 80 but also through the lower wedge opening 81, 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 is 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 defines the rearward first wedge leading edge 462 rearwardly 52, the wedge end surface 500 rises slightly rearward 52 beyond said rearward vertical surface 497 such that there is an increase 506 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 portion 501 merges tangentially into the front contact surface 466 of the front and second wedge front edge 463, respectively, in a portion associated with the front second wedge end edge 463.

The wedge 362 has a rearwardly facing outward 52 and a first wedge leading edge 462, respectively, which are a substantially planar, obliquely outwardly 52 and 115 at an inclination angle 470 to the vertical axis 148 along a Has oblique axis 469 extending contact surface 468. 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 flat against each other adjacent, relative to each other along or in the direction of the vertical axis 148, are displaceable.

Accordingly, the wedge 362 of the terminal head 361 is located when the terminal head 361 is properly mounted on a projection or on a perforated disc 44 of a vertical scaffolding or stand 41 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 on the corresponding wedge support surfaces 525, 531 of the straight inner edges of the connection head 361, while the wedge 362 at the same time with its rear, facing 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-shaped at 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.

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 gießtechnische advantages and also an overall greater carrying capacity of the connection head 361 relative to the connection head 61.

Like the connection head 61 according to the first embodiment, the slot 67 in the region of its slot bottom 103.1, 103.2 is also in the connection head 361 according to the second embodiment with a downwardly in the insertion region 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 downward 115 and rear or outside 52 to the slot bottom 103.1, 103.2 out and transitions outwardly or rearwardly 52 into the horizontal heel slot surface 107 of the heel 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 with the paragraph 100 according to the first embodiment, in the step 400, the wedge-supporting surfaces 108 of the wedge-supporting body 385 located in the region adjacent to the front releasing edge 128 are in a small vertical one Distance 429 above the paragraph slot surface 107 is arranged. 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 ( figure 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 it is not possible for a plugging or pushing the connection head 361 in the direction of forward 79 or in the radial direction of the projection or on the perforated disc 44, for example, because there is no sufficient space available or because the scaffolding component 45 provided with the connection head 361 already has its end 56.2 already pointing away from the connection head 361, in particular by means of a second connection head 61 or 361 and a second wedge 62 or 362 already on a projection or on a perforated disk 44 of another vertical scaffolding element or scaffold post 41 is fastened by means of the inserted through the opening 55 second wedge 62 and 362 such that the scaffold member 45 is pivotable in a horizontal plane relative to the projection 44.

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. Furthermore, viewed in the same vertical cross-section, outwardly 52-facing wedge support surfaces 525, 531 of both the upper abutment wall portion 363.1 of the upper head portion 374 and lower abutment wall portion 363.2 of the lower head portion 375 now extend parallel to the two abutments Supporting 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.

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. 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 radii or transition regions, extend horizontally throughout, but the slot 667 is is also limited towards the top 110 with substantially upper horizontal slot surfaces 695.1, 695.2, which, starting from the lower end of the lower insertion portion 93.2 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 is secured by means of the wedge 362 to the vertical structural element or Scaffold 41 is clamped 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 disc 44 from surface.

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 invention, in particular according to claims 1 to 9, is formed and that thus the inventive method, 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 a scaffold component according to the invention or 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 different be formed, dimensioned and / or designed or can be performed.
