Abstract

Set of parts for a fast construction scaffolding having a rosette stand (1) having the shape of a bowl and extending substantially perpendicularly to the stand axis in the ground piece (2). Said rosette stand is provided, in its peripheral area, with a circonferential flange (3) which extends upwardly; a coupling member (13) has, for at least one and preferably for each strut to be connected with the rosette, an expansible wedge effect claw (16) on the generated surface of the rosette and covers the latter from the top. For particularly heavy loads, and specially of dynamic nature, the scaffolding is given a sufficient stability in the horizontal and/or vertical direction, by means of a rigid link between each rosette and its strut, the link being comprised of a double element and/or a double lock without play. This link may be of the self-locking type even with respect to a motion in the stand axis and acts by weight effect against a loosening of the link and/or may be self-locking in the rosette stand and impeeds by weight effect impeeds the loosening of the locking.

Description

Kit for a quick scaffolding

The invention relates to a kit for a rapid scaffolding from at least one stand post and at least one on this by means of a fixed as a node on this stator rosette via a arranged at its front post end coupling element in the axial direction of the stand post by line action between this coupling member and the stand rosette non-positively lockable longitudinal cross and / or diagonal strut.

There is already known a rapid scaffolding system under the name "Layher", in which the connection of the struts with a stand tube comes about via a disk-shaped stand rosette forming a knot-shaped connecting element, which is alternately provided with smaller and larger sector-radial openings or holes. This stand rosette works to create the connection to the strut to be fixed to it with an angular coupling member of the same, in which it grips the peripheral edge area of the disk-shaped stadial rosette from the outside in a triangular and almost form-fitting manner. The locking between the stator rosette un at the stator tube-side end of the strut attached coupling member is effected in that a wedge-shaped element is passed through the body of the coupling member and leads into one of the openings or one of the holes in the stator rosette and is wedged into it. In this connection, a total of eight separate coupling elements can be assigned to such a junction in a ring arrangement around the axis of the stator tube.

In a further rapid scaffolding system known under the name "Cuplok", a node is suitable for connection with only four struts. The connection is formed by means of an integral lower shell with the stand tube, on the edge of which the struts are placed with their ends provided with diametrical connecting lips. By means of a movable ring, which bil det the upper shell of the connection, upper connection lips can be overlapped, after which this upper shell is locked or locked by suitable means by twisting on the stator tube. While in the first-mentioned quick-build system, due to its specific design, essential openings or holes in the stand rosette put a high load on the material of the junction, there is a limit for the permissible maximum load in it, with the last-mentioned quick-build scaffolding system, the application possibilities are rather limited in that, due to its specific design, Have only four struts connected to the stand tube at a node. In the latter case, however, larger loads are permitted at the node.

The invention has for its object to provide a way with simple and inexpensive means, while avoiding the disadvantages of the quick-build systems according to the prior art as far as possible, a quick-erecting scaffold of the generic type can be reused easily, quickly and conveniently from extremely inexpensive individual parts without specific specialist knowledge and special care and thus also to be able to create and dismantle with unskilled personnel at correspondingly low production costs, which allows the connection of more than only four, preferably eight and even more struts per node and at the same time can be subjected to comparatively much higher loads, particularly in the area of the stand rosette, thus has a comparatively considerably greater load capacity.

This is achieved by the invention in a surprisingly simple and economical manner in that, in the case of a kit of the generic type described at the outset, the stand rosette is cup-shaped with this base part which extends approximately normal to the axis of the stand post and extends in the area of the perepheria therefrom Above extending circumferential flange is formed and the coupling member of the or at least one, preferably each strut to be connected to the stator rosette has a cross-over position in the circumferential flange of the stator rosette from above by means of a wedge effect against a lateral surface of the same force-locking claw.

It is evident that the invention hereby goes a different way from the conceptions according to the state of the art, in that it not only avoids a weakening of the stand rosette in the sense of a reduction in its moment of resistance to bending in a plane containing its axis corresponding to the axis of the stand post, but also the presentation of a support surface corresponding to all practical requirements for not only a coupling member of a strut, but also for practically any number of the same, and this in turn in a practically unlimited size, provided only the height of the peripheral flange according to the invention of the cup-shaped stand rosette according to the invention is chosen sufficiently large. It should also be pointed out that although the simplest case of a rapid scaffolding according to the invention is a stand post with a single radially extending strut fixed to it via a stand rosette, which can be supported in some other way at its end remote from the stand post, for example by placing it in a hole in a brick wall of a building is inserted, but that a kit according to the invention has the possibility to keep open, with the highest load-bearing capacity fast-erecting scaffolding with more than four struts extending radially away per node of a stand post formed by a stand rosette according to the invention. According to an expedient training of the invention subordinate invention, the claw of the coupling member can be non-positively clamped to the outer circumferential surface of the peripheral flange of the stator rosette. For this purpose, the claw of the coupling member can advantageously have at least one contact element which interacts with the outer circumferential surface of the peripheral flange of the stator rosette. This can be designed as a claw or as a contact surface complementary to a region of the outer circumferential surface of the peripheral flange of the stator rosette. In addition, contact elements of both embodiments can be provided on a claw.

Apart from the fact that designs according to this subordinate invention principally do not require any openings or holes in the bottom part of the stator rosette, since the non-positive tensioning of the claw of the coupling member, which crosses the circumferential flange of the stator rosette, of each strut due to an extension of the coupling member engaging between an interior of the cup-like stator rosette and the inner circumferential surface of the circumferential flange of the stand rosette can be brought into effect, which can also be carried out with a sufficiently large abutment or support surface providing length without the need to pass through the bottom part of the stand rosette, should it be in the interest of an additional one Locking in the radial direction are considered necessary, within the scope of the invention it may well be possible for through openings for the lower end of such clamping wedge in the bottom part of the stand rosette e to be provided, which, in contrast to the state of the art, are then only relatively narrow and therefore only slightly impair the permissible load-bearing capacity and accordingly the load-bearing capacity of the stand rosette can. However, in this embodiment of the invention, relatively high surface pressures on the inner circumferential surface of the circumferential flange of the stator rosette are to be expected under the effect of the connected strut (s) on the stator rosette with the bending loads increasingly applied in accordance with the lever laws, unless the relatively expensive one and not inconsiderable drive-in effort, each of which is driven by a greatly widened contact surface to the inner circumferential surface of the peripheral flange of the stand rosette having clamping wedges.

Both this inconvenience and any need for openings or holes in the base part of the stand rosette, even in the event that the coupling member of a strut is to be locked in the radial direction with respect to the axis of the stand post or rosette, are surprisingly avoided by an inventive development according to another, subordinate inventive concept , according to which the claw of the coupling member can be non-positively clamped to the inner circumferential surface of the peripheral flange of the stator rosette. In an expedient development, the claw of the coupling member can have at least one contact element which interacts with the inner lateral surface of the peripheral flange of the stator rosette. This can advantageously be designed as a claw or as a complementary surface to a region of the inner circumferential surface of the peripheral flange of the stator rosette. In this embodiment of the invention, too, in the case of one or more strut (s) to be connected to the upright rosette, the associated claws can be provided with both contact element embodiments simultaneously. For more heavily loaded, in particular lateral loads, for example due to the effects of wind or quick-action scaffolding subjected to side-operated hoists or the like, in addition to securing the fixing connection of the strut (s) at the node against vertical displacement, the rapid assembly of the scaffolding system also has good stability with respect to the side Relocation components. In order to achieve this with particularly simple and economical means also in connection with a rapid scaffolding according to the invention, another subordinate concept of the invention provides that the claw of the coupling member of the or at least one, preferably each, to be connected to the stand rosette against rotation about the Axis of the stand post can be secured in a form-fitting manner on the stand rosette.

For this purpose, the lateral surface of the stand rosette provided for the fixing of coupling members of struts can have a polygonal contour with connecting surfaces corresponding to straight and / or concave and / or convexly curved connecting lines or an elliptical contour in any axis-normal section. In both cases, with preference to form a securing against relative rotation of the claw of the coupling member of a strut and stator rosette, this claw can be a part of at least one of the connecting surface of the cross-sectional polygon of the lateral surface of the stator rosette or a partial region of the cross-sectional ellipse of the lateral surface of the Stand rosette corresponding surface have complementary contact surface. In this way it is already simple and economical by the shape in the manufacture of the individual parts of the kit according to the invention a self-resulting positive locking device for the claw prefabricated when they fit together functionally.

The same applies if, according to an alternative embodiment, the lateral surface of the stator rosette provided for the fixing of coupling members of struts has a circular contour in any axis-normal section through it.

In a further development of this subordinate inventive concept, it is expediently provided in the latter case that the lateral surface of the stator rosette to be braced with the claw of the coupling member of a strut has at least one surface area deviating from the general surface contour of this lateral surface and the claw of the coupling member or at least one, each strut preferably has a contact surface that is complementary to this, but this configuration is in no way limited to stand rosettes with a circular contour of their normal axis section through the relevant lateral surface, but can equally be used for elliptical or polygonal contours with the described connecting line design.

The flat area for the positive locking against relative rotation of the claw of the coupling member of the strut and stand rosette can advantageously be formed as a flat or concave or convex surface on the stand rosette. In these cases, too, the desired positive locking against rotation can be carried out in a highly simple and economical manner already during the manufacture of the individual parts of the kit according to the invention be done.

Other tried and tested, but usually not so inexpensive, options for such positive locking devices for claws of struts to be connected to the stator rosette with respect to the claw result from the fact that the surface area of the stator rosette to be braced by the claw of the coupling member of a strut deviates from the general surface texture Surface area of this general surface contour is offset at least at one of its edge boundaries by a step extending into the material of the peripheral flange of the stator rosette and / or that the lateral surface of the stator rosette intended for fixing coupling members of struts has at least one recess and / or at least one projection and the Claw of the coupling member or at least one, preferably each strut complementary to this has a projection and / or a recess.

The rigidity of the connection between the stand rosette and the strut connected to it is required for optimal use of a quick-erecting scaffold of the generic type, and with the additional usability of the other advantages of the invention, it is comparatively larger than in prior-art quick-scaffolding systems, and experience has shown that this is also without additional protection against relative rotation of the strut or its coupling element relative to the stand rosette about its axis. This is not only due to the fact that the invention enables the contact surface between the stator rosette and a coupling member to be connected to it Strive to make it as large as possible, but also in that the invention can provide a comparatively long middle support line for the introduction of force into the stator rosette in comparison to designs according to the prior art.

The scaffold stability that can be achieved in this way is optimal with respect to designs according to the prior art, but it also has limits, as has been shown, in particular with dynamic loads in the vertical and / or horizontal direction, such as, for example, as a grandstand support or as a support quick construction scaffolding used by witnesses or the like according to the invention can occur. Here too, however, there has been a need for satisfactory structural stability for even the most extreme static and dynamic load cases via a correspondingly permanently rigid connection of each stand rosette with the longitudinal and / or associated with it and acting on it via the associated coupling element To reach cross and / or diagonal strut (s).

For this purpose, an inventive further development of the basic concept of the invention provides a non-positive double bracing of the claw of the coupling member of the or at least one, preferably each strut to be connected to the stand rosette in the direction of the axis of the stand post. In this case, according to a subordinate inventive idea which is further developed here according to the invention, the claw of the coupling member of the or at least one strut, preferably each of the struts to be connected to the stator rosette, can itself also be non-positively against the stator post against movement in axial direction tion of the same securing and tensioning member which automatically counteracts under the effect of loosening of the static friction connection.

As a result, a strength and rigidity of the Sehnell connection of the individual parts of the quick-erecting scaffold, which was previously unattainable by frictional connection, is achieved with optimum security against vertical forces acting on loosening of the same, regardless of whether these are static or dynamic, i. H. are changing with regard to size and / or frequency of occurrence.

However, in order to counter the risks of loosening the quick connections in the area of each stand rosette forming a node, for example from lateral forces or particularly unfavorable directional pulsating vertical forces, in a highly simple and cost-effective manner and yet effective in every respect, a further inventive training sees a form-fitting practically backlash-free double locking of the claw of the coupling member or at least one, preferably each, of the struts to be connected to the stand rosette in the transverse direction to the rosette axis. In a further advantageous embodiment of this subordinate inventive concept, the claw of the coupling member or at least one, preferably each, of the strut to be connected to the strut can be designed as a self-supporting system on the stator rosette and automatically counteracts under the effect of loosening the locking effect. In the case of a kit for the construction of a rapid scaffolding with stand rosette designed for non-positive clamping of the claws of the coupling members of the struts relative to the inner circumferential surface of their peripheral flange, the inventive further development of the two subordinate inventive principles described last results in a particularly simple and inexpensive to manufacture, highly economical and maintenance-free and but reliably usable design in that the peripheral flange of the stand rosette is formed on its inner circumferential surface with inclination diverging at least in some areas from the bottom part of the stand rosette in the axial direction, and in that the claw of the coupling member of the or at least one, preferably each, strut to be connected to the stand rosette is at least A complementary tilting element that can be brought into contact with this or one of these inclined surface areas (e) and on its d The free end face facing the post has at least one further contact element which can be non-positively clamped to the outer surface of the post by force in the direction of the bottom part of the post rosette. The radial distance between the effective surface of the contact element that can be braced with the inner circumferential surface of the stator rosette and the effective surface of the further contact element that can be braced with the outer surface of the stator post can expediently be greater than the clear radial distance between the stator post and the peripheral flange of the stator rosette on the inner surface of the stator rosette Bottom part of the same. The or at least one of the further contact element (s) can be used as a claw or as a loading complementary contact surface can be formed richly on the outer surface of the upright. Both embodiments can also be present at the same time for one or more or all of the claws to be fixed on a stand rosette.

If there is talk above of the action of force in the direction of the bottom part of the stator rosette, by means of which the respective claw of the coupling member of a strut can be clamped to the surface of the stator post, this can be the driving force applied by, for example, blows to the respective coupling member or its claw, or else the weight force that automatically counteracts the loosening of the connection. This can result from the own weight of the scaffolding structure and possibly also additional weight loads, it being emphasized that here, for example, pulsating weight loads occurring due to the inventive concept do not have a detrimental effect in terms of loosening the connection, but on the contrary automatically reinforce the connection and thus an improvement in the fatigue strength of the same.

It has turned out to be particularly preferred if the circumferential flange of the steel rosette is designed for simultaneous non-positive bracing of several claws of coupling members of struts to be connected to the rosette, in a distribution around the rosette axis, preferably, but not necessarily, in a uniform angular distribution. In a further expedient further training, struts can be braced on the claws of coupling members

Lateral surface of the peripheral flange of the stand rosette in predetermined angular distribution with respect to the rosette axis a plurality of complementary elements that can be brought into operative connection with at least one contact element of a claw of the coupling member of a strut can be provided. It has turned out to be sufficient for the most common practical requirements if the counter elements are arranged at an angular distance of 45 ° each.

In a further expedient development of the invention, it is provided that the coupling member of each strut to be connected to the stand rosette has a recess for receiving a freely movable wedge, by means of which the clamping force can be applied to the claw of the coupling member for its positive locking with the peripheral flange of the stand rosette . The design of the wedge itself can also contribute significantly to the optimization of the stability of the connection which is aimed for in the sense of the invention. If the wedge is given an approximately I-shaped cross-section and the outer surface of one of its transverse flanges is designed such that it can be brought into operative connection with a lateral surface of the peripheral flange of the stand rosette, a particularly favorable embodiment of the wedge results, since its two transverse flanges then serve to to optimize the effective surfaces despite the low material cross-section and correspondingly low wedge weight.

In the interest of the greatest possible achievable rigidity of the connection, further expedient further training can also ensure that the side forces directed at rotation cannot loosen the connection. For this purpose, the wedge can be non-positively secured to the stand rosette against rotation about the axis of the stand post. For this purpose, the Wedge have at least one contact element which interacts with a lateral surface of the peripheral flange of the upright rosette, which can be designed as a claw or as a complementary surface to a region of the assigned lateral surface of the peripheral flange of the upright rosette. Both versions can also be realized together on one and the same part.

As preferred in the interest of further improving the stability of the connection, it has proven to be possible if the wedge can be secured against rotation about the axis of the stand post in a form-fitting manner on the stand rosette, and this preferably at the same time with a non-positively effective securing device. For this purpose, the lateral surface of the stand rosette provided for the fixing of wedges can have a polygonal contour with connecting surfaces corresponding to straight and / or concave and / or convexly curved connecting lines, or else an elliptical contour, in any section normal to the axis. It is furthermore advantageous if, in order to form a security against relative rotation of the wedge and stand rosette, this wedge has a connection area corresponding to a partial area of at least one of the connecting surface of the cross-sectional polygon of the lateral surface of the stand rosette or to a partial area corresponding to the cross-sectional ellipse of the lateral surface of the stand rosette Surface has complementary contact surface. However, it is also expedient for the lateral surface of the upright rosette provided for fixing wedges to have at least one surface region deviating from the general surface contour of this lateral surface and the wedge to have a contact surface which is complementary to this. The surface area for the positive locking against relative rotation of the wedge and stand rosette can be designed as a flat surface or as a concave or convex surface on the stand rosette. Here, even more than with corresponding contouring of the surfaces or surface areas of claw of a coupling member to be brought into contact with one another of a coupling member of a strut to be connected to the stator rosette and the associated lateral surface of its peripheral flange on the one hand and / or the outer surface of the stator post on the other hand must be emphasized by convex or concave complementary formation of the wedge contact surface and with this cooperating outer surface of the peripheral flange of the stand rosette or the corresponding surface area thereof, regardless of the rotation lock which can be achieved at the same time, the effective surface area can be increased by at least 10% based on the effective surface area in a flat design, which can be seen the increase in the frictional engagement of both wedges to be clamped together and thus the improvement in the stability of the connection of the same benefits.

On the other hand, the surface area deviating from the general surface contour of the lateral surface of the stand rosette to be braced with the wedge can also be offset from this general surface contour at least at one of its edge boundaries by a step extending into the material of the peripheral flange of the stand rosette and / or for the fixing of Wedge provided surface of the stator rosette at least one recess and / or at least one projection and the wedge complementary to this have a projection and / or a recess. It has also proven to be expedient if the peripheral flange of the stand rosette is designed for simultaneous at least non-positive bracing of several wedges with it in a distribution around the rosette axis. It can advantageously be provided on the lateral surface provided for the fixing of wedges of the circumferential flange of the upright rosette in a predetermined angular distribution with respect to the rosette axis in each case with at least one contact element of a wedge that can be brought into active connection with complementary counterparts, these preferably being at an angle of can each be arranged at 45 °.

Although, according to the concept according to the invention, diagonal struts can in principle also be connected directly to the circumferential flange of a stand rosette, if this is designed accordingly, it has been shown, however, that it is preferable if any diagonal struts required are coupled in the same way to the stand rosette can be like longitudinal or transverse struts. In addition to the fact that in this way not inconsiderably more expensive shapes on the peripheral flange of the stand rosette and / or on the coupling member of each such diagonal strut should be avoided, it is also desirable to introduce the diagonal forces as radially as possible into the stand rosette to ensure that these diagonal forces can also be safely connected to the connection. For this purpose, in an inventive further development according to another subordinate inventive concept, the coupling member of the or at least one, preferably each strut to be connected to the stator rosette has at least one connecting element for a diagonal strut. This ensures with simple and inexpensive means that the diagonal forces are diverted in the radial direction with respect to the axis of the steel rosette before being introduced into the circumferential flange of the stator rosette already loaded by different forces from the framework. This applies to diagonal forces in both horizontal and vertical or any other direction in space. It can be seen that this preferred embodiment of the invention, according to a subordinate sub-task, significantly increases the universality of the usability of a kit according to the invention for the creation of a wide variety of construction types.

In a further expedient development of this subordinate inventive concept, each connecting element for a diagonal strut on the side of the coupling member remote from the claw can extend away from it at an angle relative to the normal main axis of the stator post. A preferred embodiment of this is characterized by two connecting elements each extending at an angle of approximately 45 ° to the main axis of the coupling member. The or at least one connection element can expediently be designed as a threaded connector, onto which the end of a diagonal strut can be screwed with a corresponding counter thread and, if necessary, can be fixed by means of a lock nut. Experiments have shown that diagonal struts can be fixed with great certainty and at the same time a quick hooking and quick clamping of the same as when fixing longitudinal and / or transverse struts on the steel rosette is guaranteed. In order to make the position of the struts to be fixed on a stand rosette simple but clearly recognizable even for inexperienced personnel, so that special care can be dispensed with when creating each junction connection of the quick-assembly scaffolding as well as lengthy testing or searching for the correct fitting position, sees another subordinate inventive concept before that the free end face of the circumferential flange of the stator rosette has at least one recess running in the axial direction for receiving the part of the coupling member which overlaps the circumferential flange of the stator rosette and has a strut to be connected to the stator rosette. In this case, a plurality of recesses can expediently be provided in the free end face of the peripheral flange of the upright rosette in a predetermined angular distribution with respect to the rosette axis and preferably be arranged at an angular distance of 45 ° in each case. It should be emphasized that the recesses in the free end face of the circumferential flange do not signal positioning positions for one coupling element in each case of a strut to be connected to the stand rosette, but equally also the areas of the circumferential flange of the stand rosette that stand up between two such recesses.

It has also proven to be advantageous if at least one drain opening for precipitation moisture is provided in the base part of the stand rosette. This allows rain, dew, melt water or, if necessary, also cleaning fluid to drain off easily, without there being any signs of weathering or corrosion. It should be emphasized that these drainage openings are not recesses or openings in the base part of the stand rosette, which would practically impair its resistance to stress. Due to the inventive concept of creating a rapid scaffolding with extremely secure connection of the coupling members of struts fixed to a stand rosette, it can facilitate the dismantling of such a quick scaffolding, in particular in embodiments of the invention in which there is double bracing and / or double locking of the type described above and / or the connection in question secures itself against loosening, finally, be expedient if, in order to fix the coupling member, the or at least one, preferably each, strut to be connected to the stand rosette, a wedge in the form of a boomerang. is provided, which has a striking surface in the area of its kink for applying the clamping force causing the clamping force. Regardless of the special embodiment of the invention, such a wedge can be driven or driven into its tensioning connection as well as a conventional kink-free wedge, but for the intended solution of a connection according to the invention, it offers a simple, yet highly effective, inexpensive handle, by simple means Swiveling actuation of the angled leg protruding freely upwards from the relevant coupling member not only to loosen the clamping connection of the other wedge leg, but also to lift the coupling member out of its abutment on the peripheral flange of the stand rosette and / or on the outer surface of the stand post, conveniently and quickly, and thereby the entire connection to loosen accordingly.

For scaffolding, it is usually preferable to use a stand rosette and coupling element (s) as drop forgings, but there are also other dimensions materials applicable, such as aluminum or wear-resistant plastics. The connection of metal coupling elements to the struts will usually be carried out as a welded joint, but depending on the size of the expected force, it can also be carried out differently, such as a screw or adhesive connection.

Colored plastics can also be used for decorative purposes, both for the struts and their coupling members and / or the stand rosettes, so that, for example, this also draws attention to such a framework at exhibitions.

In the following, the invention is explained purely by way of example with reference to a few preferred exemplary embodiments which are shown schematically in the drawings. Show:

Fig. 11 is a corresponding plan view of the coupling member, associated area of the stator rosette and Stän derpfosten according to FIG. 10, and

12 shows a side view of the stand rosette according to FIGS. 10 and 11. As can be seen from FIGS. 1 and 2, the cup-like stand rosette, designated as a whole by 1, has a base part 2 extending normally from the axis a of the stand post coaxially to this and a peripheral part 3 extending from its peripheral area approximately in the axial direction upwards . In the base part 2 there is an outer cross-sectional contour of the upright post 6, for example circular recess 4 with approximately rounded or chamfered edges ⁷ , the rigid connection of the upright rosette 1 to the upright post 6 being formed by a weld seam which is only indicated and is designated by 3. The inner circumferential surface 8 of the circumferential flange 3 is cylindrical, while the outer circumferential surface 9 has a cylindrical central region which is continued on both sides by frustoconical or spherical regions which are oblique or rounded in cross section. Openings 12 in the base part 2 are recessed for the removal of precipitation moisture.

In Fig. 2, a number of coupling members 13 and 14 is indicated schematically in dashed lines, the claws in a manner shown in Fig. 6, the upper edge of the circumferential flange 3 of the stator rosette 1 to be positively fixed to this in the axial direction a. This type of connection will be explained later.

FIG. 3 shows a particularly simple embodiment of a stand rosette 100 according to the invention which is particularly economical in terms of production technology and cost. The bottom flange 102 of the circumferential flange 103, which extends upwards in the axial direction, has an inner circumferential surface 108 that is cylindrical over its entire height and a cylindrical surface that is also cylindrical over its entire height outer surface 109.

In Fig. 6 is representative of all embodiments of stand rosettes according to the invention with the aid of a stand rosette 300, for example the embodiment shown in Fig. 3, the mode of operation of the invention is shown with respect to the inner circumferential surface 308 of the circumferential flange of the same coupling member. This coupling member is denoted here by 15 and has a claw 16 with which it engages over and behind the upstanding edge of the peripheral flange and with a surface 17 complementary to the inner lateral surface 308 of the same surface is thereby held in tight contact with it by the fact that in Fig. 7 recognizable recess 22 in the coupling member 15 reaching through and engaging on a corresponding (not designated) mating surface supporting a wedge 18, which with its post-side end face 50, which is complementary to the outer circumferential surface of the peripheral flange of the stator rosette 300, in this Facility is located. The quick release connection is effected by driving the wedge 18 in the vertical direction. It can be seen that this results in a non-positive fixing of the claw 16 with respect to relative movements of the claw 16 relative to the circumferential flange of the stator rosette 300 in the direction of its axis a and in the direction of rotation around it by tensioning by means of the wedge 18 and a positive locking of the claw 16 and the stator rosette 300 Relative movement in the normal direction to the axis a of the stator rosette 300 (radial direction) is effected by the wedge 18.

In Fig. 2 some preferred embodiments of the with the inner circumferential surface of the circumferential flange of the stand rosette according to the invention are non-positively braced the coupling members 13 and 14 indicated. 2 has the simplest form of an abutment element in that it is designed as an abutment surface 30 that is complementary to the inner circumferential surface 8 of the circumferential flange 3 of the upright rosette 1 over its entire extent is. The connection between the coupling member 13 and the circumferential flange 3 of the stator rosette 1 is achieved here only by the frictional connection between the contact surface 30 and the inner circumferential surface 8 of this circumferential flange 3.

The same applies to the embodiment of a coupling member 14 shown obliquely to the top right in FIG. 2. Here, the contact element of the claw of the coupling member 14 cooperating with the inner circumferential surface 8 of the peripheral flange 3 is designed as a pair of claws 31. These are held firmly against the inner lateral surface 8 by the action of the wedge engaging on the outer lateral surface 9 of the peripheral flange 3 of the upright rosette 1. In both cases, there is no special security against relative rotation around the rosette axis a, if one disregards the existing static friction.

This is different in the further illustrated embodiments of coupling members 13 and 14.

Thus, in the case of the coupling member 13 indicated in the center downward in FIG. 2, a region of its non-positive bracing with the inner lateral surface 8 of the peripheral flange 3 of the stator rosette 1, which is designed as a flat surface 32, is indicated by dashed lines. In this case, the inner lateral surface accordingly 8, which may also be cylindrical, has a complementary flat surface area 42, which is shown as a solid line. While maintaining the Eaftreibungsverbindung between the claw and the peripheral flange of the stator rosette, this provides a very simple protection against relative rotation of these two parts against each other.

The same applies to the design as shown in the opposite half illustration. Here, the contact surface of the claw of the coupling member 13 to be clamped non-positively with the peripheral flange of the stator rosette has a concave recess 34 in the interest of achieving an enlargement of the contact surface. Correspondingly, the inner lateral surface 8 of the peripheral flange 3 of the upright rosette 1 has a complementary convex bulge at the point in question, as shown in a solid line, which is designated by 44. The indentation 34 and the indentation 44 engage in one another without impairing the static friction connection, but at the same time bring about the desired securing against relative rotation of the claw or coupling member 13 and stand rosette 1.

This is also achieved by the design of the coupling member 14 indicated obliquely to the bottom right in FIG. 2. Here to achieve the kraftschlüssi gene adhesive connection between the coupling member or its claw and peripheral flange of the stator rosette certain contact surface of the claw, which, as shown, is essentially cylindrical, has a recess 33 approximately triangular cross-section. Correspondingly, the inner contour, which is essentially complementarily cylindrical, is complementary

The outer surface 8 of the peripheral flange 3 of the stator rosette 1 provided with a complementary projection 43. This also achieves the desired rotation lock while maintaining the required static friction lock between coupling member 14 and stator rosette 1.

Instead of a recess 33 on the claw of the coupling member and a corresponding projection 43 on the stator rosette, the arrangement can also be reversed with a recess in the peripheral flange of the stator rosette and a corresponding projection on the claw of the coupling member. Furthermore, instead of such a complementary arrangement of recess and projection, several such arrangements can be provided per coupling element. Furthermore, these complementary arrangements of recess and projection can also have other cross-sectional contours. And finally, it should be pointed out that this complementary arrangement as an anti-rotation device does not necessarily have to lie in the area of the non-positive connection between the coupling member and the stator rosette, but for manufacturing reasons, for example, also in the area of the upward-facing inner surface of the base part 2 Stand rosette 1 or the face of the claw of the coupling member pointing downward in the working position can be provided.

Yet another embodiment of a rotation lock is realized in the coupling member 13 indicated to the right in FIG. 2. Here, while maintaining the cylindrical surface contour, the inner circumferential surface 8 of the circumferential flange 3 of the stator rosette 1 is offset in each case in the region of the boundary of the region of the inner circumferential surface 8 which interacts with the claw of the coupling member 13 by a step 45 going into the material of the circumferential flange 3. Accordingly, the complemen Tare contact surface of the claw of the coupling member 13 has a stepped projection 35 with which, in the working position, the claw of the coupling member 13 complementarily engaging in the stepped recess of the circumferential flange 3 of the stator rosette 1 is held in this in the otherwise full force-fitting system, but by the Step system of both parts to each other the desired rotation lock is effected.

In Fig. 7, the alternative embodiment for a rotation lock, not shown in Fig. 2, but already mentioned above, is shown in dashed lines in the form of a projection 36 extending from the contact surface 17 of the claw 16 of the coupling member in the direction of the peripheral flange of the stator rosette , which can engage in a corresponding (not shown) recess in the area of the inner circumferential surface of the peripheral flange 3 of the stator rosette 1. In addition, FIG. 7 also shows how the connection to a strut can take place on the rear side of the coupling member 15 with the aid of the two side lugs 26 clearly shown in FIG. 8. The strut 600, shown schematically in FIG. 7 as a tube, can, for example, as indicated, be welded to the body of the coupling member 15, the two rearward-facing lateral areas 26 of the same forming a guide which engages into the tube interior of the strut 600.

9 is designed essentially in the same way as that according to FIGS. 6 to 8. As indicated in dashed lines, however, its claw has a recess 33 into which, as in FIG. 2, obliquely to the bottom right shown as a complete can engage mental projection of the peripheral flange of the stator rosette. Furthermore, the rear, strut-side end of the body of the coupling member is of solid triangular design, with the main axis b of the coupling member corresponding to the main connection direction of the struts on a node rosette at an angle of 45 ° and one another at an angle of 90 extending surfaces Threaded bolt 24 or 25 extends as a connecting element for one diagonal strut. These diagonal struts put quite high loads on the connection, which can adversely affect the stability and safety not only of the same, but of the entire scaffold construction. Precisely by the combination of positive locking of the coupling member with the peripheral flange of the stator rosette in the direction of the rosette axis a and in the direction of rotation about this and the locking of both parts already described in connection with FIG. 6 in the radial direction to the rosette axis a on the one hand and the initiation of the oblique direction Diagonal forces to be absorbed into the coupling member and their transformation into a force acting in the direction of the main axis b of the same prior to their introduction into the connection between the coupling member and the circumferential flange of the stator rosette, these disadvantages are effectively and reliably eliminated, with the largest possible contact surfaces being able to be brought into effect, which benefits the desired stability overall. It should be emphasized that - while in Fig. 9 the bolt ends 24 and 25 are provided as connecting elements for diagonal struts in an approximately horizontal plane in the working position of the coupling member - these connecting elements for diagonal struts are also rotated through 90 ° about the main axis b of the coupling member Arrangement can be provided so that in the working position of the coupling member whose rear end is suitable for connection in egg offers diagonal struts running vertically.

4 and 5 show a further preferred embodiment of a stand rosette 200 with a base part 202 of a previously described or other design and extending from its peripheral edge area upward in the circumferential flange 203, approximately in the axial direction a, with a non-positive connection which has already been described in connection with FIG. 6 with simultaneous positive locking interlocking formed inner surface 208. The upwardly facing free end face 203 'of the circumferential flange 203 has, in the illustrated embodiment, as shown in FIG. 5, at an angular distance of 90 °, a plurality of recesses 204 of predetermined sector size in the illustrated embodiment in the illustrated embodiment 5, from 45 °, on. This sector size should be appropriately matched to the corresponding claw width of the coupling elements to be used, so that they can be brought into the correct division of labor on the one hand very quickly and without special skill or specific experience, and on the other hand, by attaching to the Lateral recesses delimiting recesses of the upstanding lobes of the circumferential flange 203 of the upright rosette 200 are positively locked themselves against rotation about the rosette axis a. If, moreover, the sector widths of the recesses 204 are selected so that they correspond to the width of the upstanding tabs 205 remaining between two recesses 204, this furthermore advantageously becomes advantageous for the rapid centering of the coupling members to be fixed on a stand rosette 200 and their positive self-locking against rotation about the rosette axis a contributed by then namely the side surfaces of two inserted into adjacent recesses 204 Klihkte coupling members take over the function of radial centering for a further coupling member introduced between them, the upstanding tab 205 of the coupling flange 203 located between them.

While for less loaded scaffolding structures, such as only decorative scaffolding for exhibitions or the like, where it is of primary importance that the assembly can be carried out easily and quickly, the wedge 18 providing the bracing effect can only be designed as a simple sheet metal part on both sides with a flat Läjigs surface finish, attempts have been made provided that because of the rather small effective surface between the end face of the wedge and as a counter surface for this acting outer lateral surface of the peripheral flange of the stand rosette, such a connection for larger loads, in particular with time fluctuations, as is to be assumed, for example, in grandstand construction or the like, may be inadequate. Here, according to the invention, a corresponding enlargement of the surface effective between the wedge and the circumferential flange of the stand rosette can provide a simple and economical remedy, while at the same time being effective and highly reliable. In the preferred embodiment of a wedge 18 shown in FIG. 9, it therefore has an approximately I-shaped cross section, as shown. The outer surface 23 of one or both transverse webs 20, 21 may be flat or concave or also convexly curved, for which the outer circumferential surface of the peripheral flange of the stator rosette naturally has to have correspondingly curved counter surfaces. 9 is. only shown, for example, that the outer end face 23 of the transverse flange 20 of the wedge is concavely curved, while the outer end face of the opposite transverse web 21 of the wedge is flat.

By enlarging the between the wedge and the peripheral flange As has been shown by tests, the surface rosette of the respective effective rosette can significantly increase the overall stability of the connection. This applies in particular if the wedge has an I-profile, which makes it particularly stressful. To increase the load-bearing capacity by improving the kink resistance of the wedge, it is also possible to narrow the recess 22 in the coupling member (not shown), as a result of which the flat wedge center web 19 can be guided in a manner that is favorable for this purpose. It should also be emphasized that even if a concavely curved end face 23 is jammed with a flat counter surface on the outer circumferential surface 309 of the circumferential flange of the stand rosette, a stable connection is also achieved in that the jamming then takes place on two parallel lines substantially outside of the Wedge central longitudinal plane takes place in that the protruding outer regions of the end face 23 of the wedge then act as a kind of claws.

In the left circular section in FIG. 6 it is shown that the wedge 18 can rest on the outer surface 309 of the peripheral flange 303 of the stand rosette 300 with a complementary end face. If an additional rotation lock is desired, a nose 56 can be provided on the free end face 50 of the wedge 18, as is further clarified in this circular cutout, which nose in a recess, not shown, but shown in the outer circumferential surface 309 of the peripheral flange 303 of the standard rosette 1 engages and prevents the entire wedge 18 from moving laterally under side loading or undergoing a rotary movement about the steel rosette axis a. A similar rotation lock is achieved with a wedge 18 if it is guided over a step 55 which is deposited in the interior of the outer flange surface 309 of the peripheral flange 303 of the stator rosette 3, as is shown in the right circular section in FIG. 6.

Although the previously described embodiments of junction connections between coupling members of struts and stand rosettes are by no means limited to scaffolding structures with lower loads, such as exhibition walls or the like, but rather also serve well for a large number of scaffolding structures while maintaining the advantages sought according to the invention, such as in working and / or inspection platforms, test benches or the like, it can be exposed to particularly high loads, rapid scaffolding constructions, in which, in addition to high static loads, unfavorable dynamic loads are also to be expected, such as for grandstand constructions, if these also have unfavorable wind loads exposed, should be desired if additional securing of the connection against loosening of the same can be achieved under extremely unfavorable maximum loads. This is provided by the further exemplary embodiment of the invention illustrated in FIGS. 10 to 12.

Here, the design and arrangement of a stand rosette 400 on a stand post 6 is the same as already explained in the other exemplary embodiments of the invention, but with the exception that the peripheral flange 403 of the stand rosette 400 diverges upward from the bottom part 402 thereof stretched out. It is essentially only the inner circumferential surface 408 of the circumference flange 403 with which the claw 416 of the coupling member 415 must cooperate, while the outer circumferential surface of the circumferential flange 403 need not run parallel to the inner circumferential surface 408, but only needs to have suitable contact surfaces for the corresponding end faces of the wedges 418. The illustrated embodiment of the stand rosette 400, however, has manufacturing and economic advantages due to its particularly simple design.

The claw 416 of the coupling member 415 has a wedge shape with a contact surface 430 complementary to the inner lateral surface 408 of the peripheral flange 403 of the stator rosette 400 and on the opposite side contact elements 431, by means of which it is supported in the working position on the outer surface 6 ′ of the stator post 6. As can be seen from FIG. 11, these contact elements 431 are designed as claws. Instead of the two claws 431, the stator post-side surface of the claw 416 could also have had a contact surface which was complementary to the outer surface 6 'of the stator post 6 over its entire width or width or a partial region thereof. Conversely, instead of the contact surface 430, claws could also have been provided on the side of the claw 416 near the peripheral flange. In any case, the design is such that at the lower free end face of the claw 416 in FIG. 10, the radial distance between the effective surface of the contact element which can be braced with the inner lateral surface 408 of the stator rosette 400, here the contact surface 430 of the claw 416, and the effective surface of the contact element which can be clamped to the outer surface 6 'of the upright post 6, here the two claws 431, is larger than that. clear radial distance between stand post 6 and peripheral flange 403 of the stand rosette 400, measured on the upward facing inner surface of the bottom part 402 thereof.

10 to 12, a non-positive double bracing of the claw 416 of the coupling member 415 with the inner circumferential surface 408 of the peripheral flange 403 of the stator rosette 400 and on the other hand the outer surface 6 'of the stator post 6 is achieved by applying force in the direction of the stator post axis a , for example by hammer blows on the claw neck from above, the claw 416 clamps itself in the clear space between the circumferential flange 403 of the upright rosette 400 and upright 6 against movements in the direction of the upright post axis a and rotates around it, while in the manner already described, an additional one Clamping force is applied by driving the wedge 418 into the receiving recess 422 in the body of the coupling member 415.

At the same time, however, a form-locking double locking against radial movements of the claw 416 is also achieved by the claw, in addition to its locking in relation to the peripheral flange 403 of the stand rosette 400 already explained in connection with other described exemplary embodiments of the invention, by means of the wedge which is in operative connection on its outer lateral surface 416 by their abutment on the outer surface 6 'of the upright 6 is also blocked against movements in the direction of its axis a.

Obviously it is thus both caused that the claw 416 itself not only with respect to the stand rosette 400, but at the same time also with respect to the stand post 6 non-positively against movement in the axial direction thereof chert and automatically counteracts a loosening of the static friction connection not only due to its own weight but also due to additional weight, but also keeps itself in contact with the stand rosette and automatically counteracts a loosening of the locking effect under the described weight. What is special about this embodiment of the invention is not only the respective non-positive and form-fitting double protection against all possible movement options aimed at loosening the connection, but also the property of this connection, such as occurring force amplitudes directed towards particularly strong loosening of any dynamic loads, even automatically for this take advantage of spending yourself in a readjustment position that counteracts a further loosening of the connection. Although these are only the slightest compensation movements under the effect of such forces aimed at loosening the connection in the order of magnitude of only the unavoidable deformation of the material, it is precisely these slight compensation movements which automatically occur due to the shape according to the invention that are the cause of the desired self-adjustment of both the tension - As well as the locking effect of the connection in this embodiment of the invention.

It is precisely this self-adjusting effect with its positive properties for the desired high rigidity of the connection and high stability of the entire rapid scaffolding construction that is the reason why, when using wedges of a conventional design, such as such an example as shown in Fig. 6, such a connection can be solved only relatively difficult and slow. In order to make it easier to disassemble it here, the wedge 418, as illustrated in FIG. 10, has an approximately boomerang-like shape. The wedge 418 is clamped in the usual way with its downward-pointing angled leg, which can also have one of the described cross-sectional designs in adaptation to the shape of the outer circumferential surface of the circumferential flange 403 of the stator rosette 400, with the circumferential flange 403 of the stator rosette 400. For this purpose, it preferably has a striking surface 419 in the region of its kink, in the exemplary embodiment shown above it, in order to be able to drive the wedge into its working position, for example by means of hammer blows. If the connection effective in the manner described is now to be released again quickly, not only the wedge itself is loosened from its tensioning connection by means of more or less light impacts on the free leg of the wedge 418 protruding upward to the right in FIG. 10 from above and below and solved, but at the same time the claw 416 of the coupling member 415 easily, conveniently and quickly levered out of its wedge connection between the peripheral flange 403 of the stand rosette 400 and stand post 6 by loosening movements applied to it.

It should be emphasized that, also in the embodiment according to FIGS. 10 to 12, the stand rosette and the side of the claw of the coupling member of each strut that can be brought into operative connection with it can have one of the special designs already explained above in particular in connection with FIG. 2. Conversely, all of the embodiments of the invention, in which none Double bracing and / or double locking is provided, as in the exemplary embodiment according to FIGS. 10 to 12, work with a stand rosette with a circumferential flange having an inner circumferential surface which diverges from the bottom part thereof. Furthermore, all described wedge designs are possible for all embodiments of the invention. This also applies in particular to the wedge 418 according to FIG. 10, which of course can also be used advantageously in embodiments of the invention without double bracing and / or double clamping, and preferably wherever the underside of the wedge for loosening shocks to be applied there to loosen the connection is difficult to access and therefore it is advisable to apply them to the boomerang legs that are bent upwards.

In the above description of exemplary embodiments of the invention, it was assumed that the stand rosette each has an annular cross-sectional contour in any axis-normal section. It has been taken into account that the surface of the circumferential flange of the stator rosette to be brought into active connection with claws of coupling members of struts, be it the inner or the outer lateral surface of the rosette, at least in its predominant area, if not completely, ie including the one in each case a coupling member claw can be brought into operable connection areas, such as a circular contour. Obviously, this is by no means mandatory. Both the surface to be brought into operative connection with the coupling member claw and the opposite surface of the peripheral flange of the upright rosette can have any cross-sectional contour normal to the rosette axis, if only it is ensured that these surfaces are attached to suitable or have corresponding locations corresponding to predetermined locations and preferably complementary to the contact elements of the coupling member claws to be used on one side and wedge end faces on the other side. The shaping is carried out by the person skilled in the art in accordance with the respective use or application, in particular with regard to the loads to be expected in accordance with their size and / or type or direction, and taking into account the material used and its manageability in terms of machining and / or non-cutting deformability and the requirements regarding the connection connections between struts and their respective coupling member can be selected. In particular, a polygonal shape of the stator rosettes in general and in particular with respect to the axis-normal cross-sectional structure on their side that can be brought into engagement with claws of coupling members of struts can be recommended, although the round cross-sectional contouring should be preferred for most designs of quick-erecting scaffolding. It should also be emphasized that it is by no means imperative within the scope of the invention that the stator rosettes for connecting the coupling members of struts are designed with a symmetrical angular distribution with respect to the rosette axis or the axis of the stator post, if this is also the case for a simple truss design mostly recommend. In particular, stand rosettes can be used for certain scaffolding purposes within the scope of the invention, which have connection options for a lower number of coupling members of struts compared to the prior art, but offer the advantages of the type described at the outset, such as, for example, designs with triangular or hexagonal axis-normal cross-sectional contouring at least least on the side of their peripheral flange intended for connection of coupling elements.

In any case, it has been shown that the concept according to the invention fully meets all practical requirements and, in addition to the outstanding strength properties of the individual junction connections and the resulting extreme stability of the entire assembly of rapid scaffolding, this also leads to previously unachievable reductions in the assembly structure, even under the most unfavorable loading conditions. and disassembly tents. Otherwise, the invention is not limited to the illustrated and explained exemplary embodiments, rather, the person skilled in the art has a wide range of possibilities, by combining their features and / or exchanging them for equivalent means, to adapt them to the particular material and / or production conditions and / or in particular to adjust the demands of the respective application without leaving the scope of the invention.
