METHOD FOR EQUIPING A SUPPORT SCAFFOLD AND SUPPORT SCAFFOLD

Description

[0001] The state of the art is defined by CN 111 005 543 B, CN 208 363 546 U, US 4 106 256 A, DE 199 50 615 A1, US 4 546 591 A, WO 2014 / 186906 A1, US 5 273 415 A and DE 20 2021 104799 U1.

[0002] Supporting or shoring systems are used in construction to support formwork or parts of structures, such as tunnel ceilings or bridge elements, during the construction phase or during repair work. To facilitate transport and to allow adaptation to a wide variety of structure shapes and environmental conditions, supporting or shoring systems usually consist of individual scaffold modules that can be connected to one another. A supporting or shoring system can, for example, have a large number of interconnected identical scaffold modules. Such a support system with elongated beams, to which connectors can be mounted using bolts, is known from EP 3 715 548 A1. Struts can be attached to the connectors.

[0003] A disadvantage, however, is the difficult assembly of such support structures with elongated longitudinal beams, which are usually brought into position using a lifting device, especially a crane, and connected to each other via individual struts. During assembly, the individual struts must be connected to the longitudinal beams one after the other. When connecting a second longitudinal beam, a strut mounted on the first longitudinal beam is not fixed in position, so the individual strut must be precisely aligned with the second longitudinal beam. Therefore, it is advisable to connect the individual struts using a strut structure, d.h. The aim is to replace a prefabricated frame, which is mounted in a predetermined, fixed position on the first beam before the second longitudinal beam is connected to the strut structure. However, this presents the problem that the second beam must simultaneously be aligned at a larger number of connection points within such a strut structure. This requires precise handling of the second longitudinal beam, which necessitates trained personnel and is extremely time-consuming. Furthermore, the connection points must exhibit comparatively large tolerances, which reduce the load-bearing capacity in the assembled state.

[0004] In contrast, the object of the present invention is to alleviate or eliminate at least some disadvantages of the prior art. In particular, the invention aims to simplify the assembly of a support structure made of longitudinal scaffold elements using strut elements, without impairing the load-bearing capacity of the resulting support structure.

[0005] This problem is solved according to a first alternative using a method according to claim 1 and according to a second alternative using a method according to claim 3. Preferred embodiments are specified in the dependent claims.

[0006] The procedure for erecting the supporting structure of the first alternative involves at least the following steps: Providing a first scaffold component with a first longitudinal scaffold element and a second scaffold component with a second longitudinal scaffold element, wherein a first brace cross, preferably a first diagonal cross, and a second brace cross, preferably a second diagonal cross, are mounted on the first longitudinal scaffold element of the first scaffold component, wherein the first and the second brace cross each have a first brace element with a first connection point, in particular with a first connecting tab, and a second brace element with a second connection point, in particular with a second connecting tab, wherein at least one of the first brace elements, preferably both first brace elements, and in particular also the second brace elements, of the first and the second brace cross are extendable from a shortened intermediate position to an extended assembly position, in particular telescopically.Arrange at least one of the first strut elements, preferably both first strut elements, of the first and second strut cross in the shortened intermediate position; connect the second connection points of the second strut elements of the first and second strut cross, preferably via bolted connections, to the second longitudinal frame element of the second frame component; extend the first strut element, preferably both first strut elements, from the shortened intermediate position to the extended assembly position; and connect the first connection point of the first strut element, preferably both first strut elements of the first and second strut cross, preferably via further bolted connections, to the second longitudinal frame element of the second frame component.

[0007] This method significantly simplifies the assembly of the support structure. To connect the second and first scaffold components, only the second connection points of the second strut elements of the first and second strut crosses are initially connected to the corresponding connection points of the second longitudinal scaffold element, particularly via bolted connections, in a reversibly detachable manner. Preferably, both first strut elements are arranged in the shortened intermediate position, so that the first connection points are located closer to the first longitudinal scaffold element than the second connection points of the first and second strut crosses.When arranging the second scaffold longitudinal element, only the connections to the second set of braces need to be made initially. At least one of the first braces is then connected to the second scaffold longitudinal element in the next step, after being extended, particularly telescoping, into its extended assembly position. This significantly simplifies the handling of the second scaffold longitudinal element during assembly, as fewer connection points need to be aligned in the same step. If the first and second brace crosses were constructed from fixed-length braces, all braces would have to be positioned at the corresponding connection points of the second scaffold longitudinal element. This would place high demands on the handling of the second scaffold longitudinal element.The method according to the invention allows the second longitudinal scaffold element to be assembled significantly faster and more easily. The first and second strut elements of the first and second strut crosses, respectively, are preferably connected to each other in such a way that the second longitudinal scaffold element, in the intermediate position of at least one first strut element, is independently held in its final assembly position at the first and second strut crosses. Thus, the second longitudinal scaffold element is already held in position relative to the first longitudinal scaffold element before at least one of the first strut elements is extended and connected to the second longitudinal scaffold element. The embodiment according to the invention also has the advantage that the tolerances of the connections between the first and second strut crosses and the second longitudinal scaffold element can be kept small. This has a beneficial effect on the stability and load-bearing capacity of the supporting scaffold.

[0008] In the prior art (see CN 111005543 A and CN 208363546 U), support structures with telescopic connecting elements are known, but these are used only for the secondary purpose of changing the horizontal distance between vertical posts. Apart from the different objective, the known designs would also be structurally unsuitable for carrying out the method according to the invention.

[0009] The extendable strut elements, i.e. the first strut elements and preferably also the second strut elements, preferably have releasable fixings in order to be able to fix the respective strut element in the shortened intermediate position and in the extended assembly position, preferably also in further positions, in length.

[0010] In an embodiment of the extendable strut elements as telescopic elements with an inner and an outer part, the releasable fixings preferably each have a locking bolt that can be arranged in a locking opening of the respective strut element to block this strut element against length changes due to telescoping. If the second strut elements are telescopic, they form stable supports in the extended assembly position due to the releasable fixings. These supports can bear the second longitudinal scaffold element before at least one of the first strut elements is moved into the extended assembly position and connected to the second longitudinal scaffold element. Stable supports for the second longitudinal scaffold element are also achieved if the second strut elements are fixed in length and only at least one of the first strut elements is telescopic.

[0011] The extendable strut elements can alternatively be designed as spindle elements. In this design, the length of the respective strut elements can be adjusted by means of spindles.

[0012] In one embodiment, the first scaffold component comprises a single first longitudinal scaffold element or several first longitudinal scaffold elements arranged in a line, which are connected via the first and second brace crosses to a single second longitudinal scaffold element or several second longitudinal scaffold elements arranged in a line of the second scaffold component. Additional brace crosses may be provided in addition to the first and second brace crosses.

[0013] In a further embodiment, the first and second scaffold components are designed as first and second scaffold panels, respectively, with at least two first and second longitudinal scaffold elements arranged at a transverse distance from each other and preferably connected to each other via strut connections. Preferably, at least one first and one second strut cross are mounted on each of the first longitudinal scaffold elements arranged at a transverse distance from each other. At least one of the first strut elements, preferably both first strut elements, of the first and second strut crosses on the transversely spaced first longitudinal scaffold elements are arranged in the shortened intermediate position, while the second strut elements of the first and second strut crosses on the transversely spaced first longitudinal scaffold elements are connected to the second longitudinal scaffold elements of the second scaffold component.Subsequently, the first strut elements arranged in the shortened intermediate position are extended and also connected to the second longitudinal scaffold elements.

[0014] In a preferred embodiment, the first scaffold component is arranged in a horizontal position on a base. The second scaffold component is then lowered onto the second strut elements of the first and second strut cross using a lifting device, particularly a crane. The second connection points of the second strut elements are then connected to the second scaffold component, preferably via bolted connections. At least one of the first strut elements, preferably both, is then extended and connected to the second scaffold component, preferably via further bolted connections. Advantageously, crane operating times can be minimized and construction progress accelerated.

[0015] During the assembly of the support structure, the first scaffold component is placed in a horizontal position, preferably essentially horizontal, on the base, which can be a construction site floor or a support element placed on the ground, for example, at least one square timber. The second scaffold component is then lowered from above onto the first and second cross braces using a hoist. Since at least one of the first cross braces is arranged in the shortened intermediate position, the assembly of the second scaffold component to the first and second cross braces is simplified. Instead of four connections, only three, or if both first cross braces are arranged in the shortened intermediate position, only two connections between the second scaffold longitudinal element and the first and second cross braces need to be made initially.This significantly simplifies the delicate process of placing the second scaffold section onto the first and second cross braces. The first cross brace, at least one of which is in its shortened intermediate position, can then be extended and connected to the second scaffold section, with the second section already in its final position relative to the first. Naturally, any number of cross braces can be used as intermediate supports for the second scaffold section, depending on the requirements and length.

[0016] According to the first alternative solution, the supporting structure, which is in particular a preferably vertically rising scaffold tower or a preferably horizontally extending scaffold truss, has at least the following features: a first scaffold component with a first longitudinal scaffold element and a second scaffold component with a second longitudinal scaffold element, a first brace cross, preferably a first diagonal cross, and a second brace cross, preferably a second diagonal cross, wherein the first and the second brace cross each have a first brace element and a second brace element which are connected to each other, wherein one end of the first and the second brace elements are mounted on the first longitudinal scaffold element of the first scaffold component, wherein the other ends of the first and the second brace elements form first and second connection points, preferably first and second.second connecting tabs, each of which is detachably mounted, preferably via bolted connections, on the second longitudinal frame element of the second frame component, wherein at least one of the first strut elements, preferably both first strut elements, and in particular also the second strut elements, of the first and second strut cross are length-adjustable, in particular telescopically.

[0017] Preferably, the first strut elements, and preferably also the second strut elements, of the first and second strut cross are designed as telescopic elements, i.e., as strut elements whose length can be changed by telescoping, or as spindle elements.

[0018] Preferably, the first and second connection points are located at the longitudinal ends of the first and second strut elements, respectively, furthest from the first longitudinal frame element. The first and second connection points preferably have connecting openings, in particular through-openings extending transversely to the longitudinal direction of the respective first and second strut element. Connecting bolts are preferably arranged in the connecting openings to form the bolted connections. Preferably, locking bolts are provided as connecting bolts, which completely penetrate the connecting openings designed as through-openings and corresponding through-openings on the second longitudinal frame element. When installed at the through-openings, the locking bolts can each be secured against unintentional removal by a cotter pin.

[0019] The first and second connecting openings are preferably provided on the first and second connecting tabs, respectively, which are located at the longitudinal ends of the first and second strut elements, respectively, that are facing away from the first longitudinal scaffold element.

[0020] To allow for different distances between the first and second longitudinal scaffold elements, in a preferred embodiment the first and second strut elements of the first and second strut crosses are each connected to each other via a hinge. Depending on the rotational position of the first strut element relative to the second about the hinge, the transverse distance between the first and second longitudinal scaffold elements, i.e., the distance perpendicular to the longitudinal axes of the first and second longitudinal scaffold elements, can be adjusted. A second adjustment can be made for this purpose. Depending on the embodiment, the attachment points for the strut crosses along the longitudinal scaffold elements and / or the lengths of the strut crosses can be changed.

[0021] In a preferred embodiment, the first and second strut elements each have a first longitudinal end part, a second longitudinal end part and a central part, wherein the joint connects the central parts of two strut elements to each other.

[0022] If the first and second strut elements are designed accordingly and the joint is provided centrally on the central parts, the first and second strut crosses can each be designed as diagonal crosses.

[0023] If the central part of one of the first and second strut elements has a receiving opening through which the central part of the other of the first and second strut elements is guided, a statically favorable solution can be achieved.

[0024] It is particularly preferred if the first and second strut elements of the first and second strut crosses are each arranged in the same plane perpendicular to the joint axis. In this embodiment, the longitudinal axes of the first and second strut elements of the first and second strut crosses each span a common plane, which extends substantially perpendicular to the joint axis of the joint.

[0025] The assembly of the support frame can be particularly easy and safe if the first longitudinal end part and the second longitudinal end part are each telescopic relative to the central part.

[0026] In a preferred embodiment, the first and / or the second connection points are formed by first and / or second connecting tabs, respectively.

[0027] Preferably, at least one of the first and second connecting tabs each has two connection openings for further struts.

[0028] The problem according to the invention can alternatively also be solved with the second alternative of the method for constructing a support structure, as defined in claim 3. This second alternative comprises the following steps: Providing a first scaffold component with a first scaffold longitudinal element and a second scaffold component with a second scaffold longitudinal element, wherein a first and a second strut triangle are mounted on the first scaffold longitudinal element of the first scaffold component, wherein the first and the second strut triangle each have a first and a second support strut which are arranged at an angle to each other and connected to each other, and connecting stops, in particular retaining lugs, of the first and the second strut triangle, preferably via retaining bolts, to the second scaffold longitudinal element of the second scaffold component.

[0029] During the assembly of the support structure, the second longitudinal frame element is connected to the stops of the first and second brace triangles. The first and second brace elements of the first and second brace triangles are each connected to each other in such a way that, in the assembled state, the second longitudinal frame element is positioned independently at the first and second brace triangles, i.e., in particular without the aid of a lifting device, in the predetermined position, especially parallel to the first longitudinal frame element. In contrast to a connection via two individual braces, the first and second brace triangles form stable supports between the first and second longitudinal frame elements. The triangular shape minimizes the number of stops required when assembling the second longitudinal frame element, thus significantly simplifying handling. Preferably, the first and second brace triangles each have only a single stop.

[0030] In this process, before or after connecting the stops of the first and second strut triangles with the second scaffold longitudinal element of the second scaffold component, at least one further strut is mounted on the first scaffold longitudinal element of the first scaffold component, which, after connecting the stops of the first and second strut triangles with the second scaffold longitudinal element of the second scaffold component, is connected to the second scaffold longitudinal element.

[0031] In this embodiment, at least one further brace is mounted on the first longitudinal frame element of the first scaffold component. This brace is then connected to the second longitudinal frame element of the second scaffold component after the stops of the first and second brace triangles have been connected to the second longitudinal frame element of the second scaffold component. This significantly simplifies the assembly of the second scaffold component. First, the second longitudinal frame element is connected to the first and second brace triangles, which hold the second longitudinal frame element at the predetermined, parallel distance to the first longitudinal frame element. This is particularly advantageous when, as described above in connection with the first alternative solution, the second scaffold component is lowered from above onto the first and second brace triangles using a lifting device, such as a crane.This requires precise handling of the second scaffold component, which is made more difficult by each additional connection point. In a preferred embodiment, the additional bracing is initially arranged in an inactive position on the first longitudinal scaffold element, in which an additional stop for the additional bracing, for connecting it to the second longitudinal scaffold element, is located closer to the first longitudinal scaffold element than the stops of the first and second bracing triangles.

[0032] After connecting the stops of the first and second strut triangles to the second scaffold longitudinal element of the second scaffold component, the further bracing can be arranged in an active position and the additional stop of the further bracing can be connected to the second scaffold longitudinal element of the second scaffold component.

[0033] Depending on the design, the additional bracing can be mounted on the first longitudinal scaffold element while the second scaffold component is being lowered, particularly in a folded and / or shortened position. Alternatively, the additional bracing can be mounted on the first longitudinal scaffold element only after the stops of the first and second bracing triangles have been connected to the second longitudinal scaffold element of the second scaffold component, while the second longitudinal element is in the inactive position.

[0034] Once the second scaffold component has been connected to the first and second strut triangles, the further bracing can be moved from the inactive position to the active position, in particular unfolded and / or extended, and connected to the second longitudinal scaffold element of the second scaffold component.

[0035] The first and / or the second support strut of the first and / or the second strut triangle can be extended, in particular telescopically, in order to adjust the transverse distance between the first and the second longitudinal scaffold element or to facilitate the installation process.

[0036] In a preferred embodiment, the further bracing is constructed according to the first and second strut triangles with a first and a second support strut.

[0037] In a first embodiment, the first support strut of the further bracing is initially connected to the first longitudinal frame element; the second support strut is detached from the attachment point where it is connected to the first longitudinal frame element in the active position. To connect it to the second longitudinal frame element, the second support strut of the further bracing is unfolded and attached to the attachment point on the first longitudinal frame element. In a preferred embodiment, the first and / or the second support strut of the further bracing is extendable, in particular telescopically. In this embodiment, the further bracing can be brought into the active position by changing its length, in particular by telescoping.This places the additional stop of the further bracing at the level of the stops of the first and second bracing triangles, where the connection with the second longitudinal scaffold element can be made, in particular via a bolted connection.

[0038] If the first and / or second support strut of the additional bracing is extendable, particularly telescopic, then alternatively, the first and second support struts of the additional bracing can be attached to the first longitudinal frame element in a triangular shape and brought into the active position by extending them. With this variant, unfolding the additional bracing is unnecessary.

[0039] In a preferred embodiment, the first and second support struts of the first strut triangle and the first and second support struts of the second strut triangle each form a substantially right-angled triangle, wherein one end of the first and second support struts is connected to the respective retaining tab and the other end of the first and second support struts is mounted at a longitudinal distance from each other on the first longitudinal scaffold element of the first scaffold component.

[0040] The supporting structure, in particular scaffold tower or scaffold truss, of the second alternative solution according to the invention has at least the following features: a first scaffold component with a first scaffold longitudinal element and a second scaffold component with a second scaffold longitudinal element, wherein a first and a second strut triangle are mounted on the first scaffold longitudinal element of the first scaffold component, wherein the first and the second strut triangle each have a first and a second support strut which are arranged at an angle to each other and connected to each other, wherein stops, in particular retaining lugs, of the first and the second strut triangle are connected, preferably via retaining bolts, to the second scaffold longitudinal element of the second scaffold component.

[0041] Preferably, the first and second support struts of the first and second strut triangles are connected to each other via the first and second retaining tabs, respectively.

[0042] The drawings show exemplary embodiments of the invention. Fig. 1 shows the first step of an assembly method according to the invention, in which strut crosses are mounted on a first longitudinal scaffold element, two telescopic strut elements of the strut crosses are arranged in an extended assembly position and the remaining strut elements of the strut crosses are arranged in a shortened intermediate position.

[0043] In the Fig. 1 bis 3 is a first method for constructing a support structure 1 (see Fig. 3 ) shown.

[0044] According to Fig. 1 A first scaffold component 2 is arranged lying on a base, which may be a floor surface. The first scaffold component 2 has at least one first longitudinal scaffold element 3 extending along a longitudinal axis. In the example shown, two first longitudinal scaffold elements 3 are connected to each other via connecting flanges 4 such that the longitudinal axes of the first longitudinal scaffold elements 3 are aligned. Depending on the length of the supporting scaffold 1, any number of first longitudinal scaffold elements 3 can be provided. For connection to each other, the first longitudinal scaffold elements 3 can have connecting flanges 4 at their longitudinal ends. The first longitudinal scaffold elements 3 each have longitudinally spaced supports 5 on which at least one first cross brace 6, here a first diagonal cross brace, and at least one second cross brace 7, preferably a second diagonal cross brace, are reversibly and detachably mounted.In the example shown, further cross braces 8 are reversibly and detachably mounted on the first longitudinal scaffold elements 3. The first cross brace 6, the second cross brace 7, and the further cross braces 8 are identical in design. In the example shown, the first 6 and the second cross brace 7, as well as the further cross braces 8, are connected to the brackets 5 of the first longitudinal scaffold elements 3 via bolted connections 19. The first cross brace 6, the second cross brace 7, and the further cross braces 8 each have a first brace element 9 with a first connection point, here with a first connecting tab 10, and a second brace element 11 with a second connection point, in particular with a second connecting tab 12, at their free longitudinal ends.At least the first strut elements 9 of the first 6 and the second strut cross 7 are telescopically extendable from a shortened intermediate position to an extended assembly position. In the example shown, the second strut elements 11 of the first 6 and the second strut cross 7, as well as the first 9 and the second strut elements 11 of the further strut crosses 8, are also telescopically extendable.

[0045] In the first step, the second strut elements 11 of the first 6 and the second strut cross 7 are arranged in the extended assembly position. At least one of the remaining strut elements is arranged in the shortened intermediate position. In the example shown, the first strut elements 9 of the first 6 and the second strut cross 7, and here also the first 9 and the second strut elements 11 of the further strut crosses 8, are arranged in the shortened intermediate position. In this state, the second connection points, here in the form of the second connecting tabs 12, of the second strut elements 11 are essentially on the same plane, which in Fig. 1 This is illustrated by line 13. The remaining connection points of the remaining first 9 and second strut elements 11 are located closer to the first longitudinal scaffold element 3, i.e., further down in the position shown.

[0046] In the second step, see: Fig. 2 A second scaffold component 14, comprising at least one second scaffold longitudinal element 15 (here, two second scaffold longitudinal elements 15), is brought into position using a lifting device 16, which is only symbolically illustrated here. The second scaffold longitudinal element 15 is identical to the first scaffold longitudinal element 3; however, the lengths may differ depending on the design. The second scaffold component 14 is lowered from above onto the level 13 of the second connection points of the first 6 and second cross brace 7. The first 6 and the second cross brace 7 of the first 6 and the second cross brace 7 are each connected to a joint axis 18 via a hinge 17 (see in detail Fig. 7 and Fig. 8 ) connected to each other. This means that the first 6 and the second strut cross 7 are positioned in the intermediate position in a fixed arrangement relative to each other as shown by the first 9 and second strut elements 11.

[0047] In the third step, see: Fig. 3 First, the second connection points of the second strut elements 11 of the first 6 and second strut cross 7 are connected to the second scaffold longitudinal elements 15 of the second scaffold component 14 via bolt connections 19. The remaining strut elements are still in their shortened intermediate position. Due to the articulated connections of the first 9 and second strut elements 11, the first 6 and the second strut cross 7 are arranged in stable support positions, in which the second scaffold longitudinal elements 15 are independently supported by the first 6 and second strut cross 7 via the bolt connections 19. Then, the first strut elements 9, and in the example shown also the first 9 and second strut elements 11 of the further strut crosses 8, are telescoped from the shortened intermediate position to the extended assembly position, so that the corresponding connection points are arranged at the level of plane 13.Afterwards, the first connection points of the first strut elements 9 of the first 6 and the second strut cross 7, and in the example shown also the first and second connection points of the further strut crosses 8, preferably also via bolt connections 19, can be connected to the second scaffold longitudinal elements 15 of the second scaffold component 14.

[0048] Fig. 4 und Fig. 5 show a variant of the one in the Fig. 1 bis 3 illustrated assembly method. In this variant, the first scaffold component 2 has at least two first scaffold longitudinal elements 3 arranged at a transverse distance, i.e. at a distance perpendicular to their longitudinal axes, to form a first scaffold slab, which are connected to each other via strut connections 20 corresponding to the first 6 and second strut cross 7.

[0049] According to Fig. 4 The first scaffold disc is arranged horizontally, here on a base which can be a floor surface. On the opposing first longitudinal scaffold elements 3, first 6, second 7 and further cross braces 8 are arranged according to the embodiment of the Fig. 1 bis 4 The second connection points are arranged by telescoping the second strut elements 11 of the first 6 and second strut crosses 7 onto level 13. The connection points of the remaining strut elements 9, 11 are positioned by telescoping them into the shortened intermediate position closer to the first longitudinal scaffold elements 3, i.e., in the position shown below level 13.

[0050] According to Fig. 5 The second scaffold component 14 is brought into position using the lifting device 16. In the embodiment of the Fig. 4 und Fig. 5 The second scaffold component 14 is designed as a second scaffold slab corresponding to the first scaffold component 2, which has second longitudinal scaffold elements 15 arranged at a transverse distance from each other and connected to each other via further strut connections 21 corresponding to the first 6 and second strut crosses 7. The second scaffold component 14 is lowered to level 13 and connected via the connections, in particular bolted connections, to the second connection points of the first 6 and second strut crosses 7 arranged on level 13. Subsequently, the remaining strut elements 9, 11 are extended and connected to the second scaffold component 14 to form the supporting scaffold 1.

[0051] Fig. 6 Figure 1 shows the support structure 1 in its assembled state. In the example shown, the support structure 1 is designed as a scaffold tower. For this purpose, the support structure 1 is moved from its horizontal position according to... Fig. 5 into the vertically projecting position according to Fig. 6 The support structure 1 can, however, also be arranged in a lying, especially horizontal, state as a scaffold girder, also referred to as a framework girder. Formwork (not shown), especially for bridge construction, can be mounted on the support structure 1.

[0052] Fig. 7 and Fig. 8 The first strut cross 6 is shown in detail, with the other strut crosses being designed accordingly. Fig. 7 and Fig. 8 The first strut cross 6 is shown in different angular positions of the first strut element 9 relative to the second strut element 11. The angular position can be adjusted by rotating it about the joint 17. This allows for different transverse distances between the first 3 and second longitudinal frame element 14. The first 9 and the second strut element 11 each have a first longitudinal end section 22, a second longitudinal end section 23, and a central section 24, with the joint 17 connecting the central sections 24 of the first 9 and second strut element 11. The central section 24 of the second strut element 11 has a receiving opening 25 through which the central section 24 of the first strut element 9 is passed. The first 9 and the second strut element 11 are arranged in the same plane perpendicular to the joint axis 18.In the embodiment shown, both the first longitudinal end section 22 and the second longitudinal end section 23 are telescopic relative to their respective central section 24. The first 9 and the second strut element 11 can be fixed in various telescopic positions by means of releasable fixings 26, here with locking bolts 27. In the example shown, the first 10 and the second connecting tab 12 are fixedly connected to the first longitudinal end sections 22 of the first 9 and second strut element 11, respectively. Furthermore, additional connecting tabs 28 are provided on the second longitudinal end sections 23 for mounting on the first frame component 2. The additional connecting tabs 28 are identical in design to the first 10 and second connecting tab 12, respectively.To form the bolted connection 19 with the first 3 or second longitudinal frame element 15, the first 10 and the second connecting link 12, and here also the further connecting links 28, each have a connecting opening 29 in the example shown, in which a connecting bolt 30, in particular a locking bolt, can be arranged. Furthermore, the first 10 and the second connecting link 12, and here also the further connecting links 28, each have two connection openings 31 spaced apart from the connecting opening 29 for connecting further struts (not shown) or for parking connecting bolts.

[0053] In the Fig. 9 bis 11 is a second method for building the in Fig. 12 The supporting structure shown is 1. The following discussion focuses solely on the differences compared to the previous version.

[0054] According to Fig. 9 The first scaffold component 2, which here, for example, comprises two first longitudinal scaffold elements 3, is arranged lying down, in particular horizontally, on the base. A first 32 and a second brace triangle 33 are mounted on the first longitudinal scaffold elements 3 of the first scaffold component 2. The first 32 and the second brace triangle 33 each have a first, here telescopic, support strut 34 and a second, here non-telescoping, support strut 35, which are arranged at an angle to each other, here substantially at right angles, and are connected to each other in a stable triangular form. The first 34 and the second support struts 35 are connected to each other at the converging ends of the first 32 and second brace triangle 33, respectively, by means of stops, here retaining lugs 36. The retaining lug 36 can be identical to the first connecting lug 10 in the previous embodiment.The opposite ends of the first 34 and second support strut 35 are spaced apart from each other in the direction of the longitudinal axis of the first scaffold component 2 and connected to the first longitudinal scaffold elements 3 via further stops 37. The retaining lugs 36 each have a retaining opening 38 corresponding to the connecting opening 29 in the preceding embodiment. A retaining bolt 42 (see figure) can be inserted through the retaining opening 38. Fig. 10 ) corresponding to the connecting bolt 30 in the preceding embodiment. In addition, the retaining tabs 36 have two openings 39 spaced apart from the retaining opening 38, one of which can be used to connect the second support strut 35 and the other of which can be used to connect a further strut (not shown).

[0055] As from Fig. 9 As can be further seen, at least one additional brace 40 is mounted on the first scaffold component 2. In the example shown, one additional brace 40 is provided on each of the first longitudinal scaffold elements 3.

[0056] According to Fig. 9 The further bracing 40 is mounted in a folded-in inactive position on the first longitudinal frame element 3. In the example shown, the further bracing 40 are constructed according to the first 32 and second bracing triangle 33, whereby in the folded-in inactive position the Fig. 9 the second support strut 35 is detached from the first longitudinal scaffold element 3.

[0057] According to Fig. 10 The second support strut 35 of the further bracing 40 is unfolded and attached to the first longitudinal scaffold element 3. The further bracing 40 remains in the inactive position, in which an additional stop 41, here another retaining bracket, of the further bracing 40 is located below the retaining brackets 36 of the first 32 or 32.

[0058] is arranged in the second strut triangle 33.

[0059] In the next step, see: Fig. 11 , the second scaffolding component 14 is first connected to the retaining tabs 36 of the first 32 and second strut triangle 33.

[0060] Subsequently, the further struts 40 are moved from the inactive position to the active position, in the embodiment shown by telescoping the first support strut 34 of the further strut 40.

[0061] This brings the additional stop 41 of the further bracing 40 to the level of the stops of the first 32 and second bracing triangle 33. Thus, the additional stop 41 of the further bracing 40 can now be connected to the second longitudinal scaffold element 15, here with an additional retaining bolt 42.

[0062] In Fig. 12 The supporting structure 1 is shown, which is used here as a scaffold tower in a vertical orientation.

[0063] Fig. 13 Figure 1 shows a modified embodiment of the first strut triangle 32, wherein the second strut triangle 33, and here also the further struts 40, can be constructed accordingly. In this embodiment, the first 34 and the second support strut 35 are not telescopic. In addition, the stops at the diverging ends of the first strut triangle are designed without retaining tabs, but with connecting openings. Reference number list:
