AI Technical Summary
The assembly of scaffolding structures with elongated longitudinal beams is complex and time-consuming due to the need for precise alignment of multiple connection points, requiring skilled personnel and resulting in higher tolerances that reduce the load-bearing capacity of the structure.
The method involves using telescopic strut elements with adjustable lengths, allowing for initial connection of the second longitudinal scaffolding element to the first through fewer points, which simplifies handling and alignment, and then extending the strut elements to secure the structure, maintaining low tolerances and enhancing stability.
This approach significantly simplifies the assembly process, reduces the time required for construction, and improves the load-bearing capacity of the scaffolding structure by minimizing alignment complexities and maintaining low connection tolerances.

[0001] Method for erecting a supporting scaffold and supporting scaffold
[0002] The invention relates to a method for erecting a supporting scaffold.
[0003] Furthermore, the invention relates to a supporting scaffold, in particular a scaffold tower or a scaffold truss.
[0004] Support or shoring scaffolding is used in construction to support formwork or parts of structures, such as tunnel ceilings or bridge elements, during construction or repair work. To facilitate transport and to enable adaptation to a wide variety of building shapes and environmental conditions, support or shoring scaffolding usually consists of individual scaffolding modules that can be connected to one another. A support or shoring scaffold can, for example, have a large number of identical scaffolding modules connected to one another. EP 3 715 548 A1 discloses such a supporting structure system with elongated beams, to each of which connectors can be mounted using bolts. Struts can be connected to the connectors.
[0005] A disadvantage, however, is the difficult assembly of such support scaffolding with elongated longitudinal beams, which are usually brought in using a lifting device, in particular a crane, and connected to one another via individual struts. The individual struts have to be connected to the longitudinal beams one after the other during assembly. When connecting a second longitudinal beam, a strut mounted on the first longitudinal beam is not fixed in position, so that the individual strut has to be precisely aligned with the second longitudinal beam. It is therefore advisable to replace the individual struts with a strut structure, i.e. a prefabricated frame, which is mounted in a predetermined, dimensionally stable position on the first beam before the second longitudinal beam is connected to the strut structure. However, this brings with it the problem that the second beam has to be aligned simultaneously at a large number of connection points of such a strut structure.This requires precise handling of the second longitudinal beam, which requires trained personnel and is a considerable time-consuming process. Furthermore, the connection points must have relatively large tolerances, which reduces the load-bearing capacity when assembled.
[0006] In contrast, the object of the present invention is to alleviate or eliminate at least some of the disadvantages of the prior art. The invention particularly aims to simplify the assembly of a supporting scaffold made of longitudinal scaffold elements via strut elements without compromising the load-bearing capacity of the resulting supporting scaffold.
[0007] This object is achieved according to a first alternative with a method according to claim 1 and a support structure according to claim 9, and according to a second alternative with a method according to claim 3 and a support structure according to claim 16. Preferred embodiments are specified in the dependent claims.
[0008] In the procedure for erecting the supporting structure of the first alternative, at least the following steps are carried out:
[0009] Providing a first scaffolding component with a first scaffolding longitudinal element and a second scaffolding component with a second scaffolding longitudinal element, wherein a first strut cross, preferably a first diagonal cross, and a second strut cross, preferably a second diagonal cross, are mounted on the first scaffolding longitudinal element of the first scaffolding component, wherein the first and the second strut cross each have a first strut element with a first connection point, in particular with a first connecting strap, and a second strut element with a second connection point, in particular with a second connecting strap, wherein at least one of the first strut elements, preferably both first strut elements, in particular also the second strut elements, of the first and the second strut cross are extendable, in particular telescopic, from a shortened intermediate position into an extended assembly position,
[0010] Arranging 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, connecting the second connection points of the second strut elements of the first and second strut cross, preferably via bolt connections, to the second scaffold longitudinal element of the second scaffold component,
[0011] Extending the first strut element, preferably both first strut elements, from the shortened intermediate position to the extended assembly position, and
[0012] Connecting the first connection point of the first strut element, preferably both first strut elements of the first and second strut cross, preferably via further bolt connections, to the second scaffold longitudinal element of the second scaffold component.
[0013] This method can significantly simplify the construction of the supporting scaffold. To connect the second to the first scaffold component, initially only the second connection points of the second strut elements of the first and second strut crosses are reversibly and detachably connected to the corresponding connection points of the second longitudinal scaffold element, in particular via bolt connections, while preferably both first strut elements are arranged in the shortened intermediate position, so that the first connection points are arranged closer to the first longitudinal scaffold element than the second connection points of the first and second strut crosses.When arranging the second longitudinal scaffolding element, therefore, only the connections to the second strut elements need to be made first, whereas at least one of the first strut elements is only connected to the second longitudinal scaffolding element in the next step after it has been extended, in particular telescoping, into the extended assembly position. This makes handling of the second longitudinal scaffolding element much easier during assembly, as fewer connection points need to be aligned in the same step. If the first and second strut crosses were constructed from strut elements of fixed length, all of the strut elements would have to be positioned relative to the corresponding connection points of the second longitudinal scaffolding element. This would place high demands on the handling of the second longitudinal scaffolding element.Using the method according to the invention, the second longitudinal scaffolding element can be assembled considerably more quickly and easily. The first and second strut elements of the first and second strut crosses are preferably connected to one another in such a way that the second longitudinal scaffolding element, in the intermediate position of the at least one first strut element, is independently held in the final assembly position on the first and second strut crosses. The second longitudinal scaffolding element is thus already held in position relative to the first longitudinal scaffolding element before at least one of the first strut elements is extended and connected to the second longitudinal scaffolding element. The design 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 scaffolding element can be kept low. This has a beneficial effect on the stability and load-bearing capacity of the supporting scaffold.
[0014] While support structures with telescopic connecting elements are known in the prior art (cf. CN 111005543 A and CN 208363546 U), these are used solely for the purpose of changing the horizontal spacing between vertical supports. Apart from the different objectives, the known designs would also be structurally unsuitable for implementing the method according to the invention.
[0015] 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 length in the shortened intermediate position and in the extended assembly position, preferably also in further positions.
[0016] When the extendable strut elements are designed as telescopic elements with an inner and an outer part, the releasable fixings preferably each have a locking bolt which can be arranged in a locking opening of the respective strut element in order to block this strut element against a change in length due to telescoping. If the second strut elements are telescopic, the second strut elements form stable supports in the extended assembly position due to the releasable fixings, which can carry the second longitudinal scaffolding element before at least one of the first strut elements is brought into the extended assembly position and connected to the second longitudinal scaffolding element. Stable supports for the second longitudinal scaffolding element are also achieved if the second strut elements are designed to be fixed in length and only at least one of the first strut elements is designed to be telescopic.
[0017] The extendable strut elements can alternatively be designed as spindle elements. In this design, the length of the respective strut elements can be adjusted using spindles.
[0018] In one embodiment, the first scaffolding component comprises a single first longitudinal scaffolding element or a plurality of first longitudinal scaffolding elements arranged in a line, which are connected via the first and second cross braces to a single second longitudinal scaffolding element or a plurality of second longitudinal scaffolding elements of the second scaffolding component arranged in a line. In addition to the first and second cross braces, further cross braces may be provided.
[0019] In a further embodiment, the first and second scaffolding components are designed as a first and second scaffolding panel, respectively, with at least two first and second longitudinal scaffolding elements arranged at a transverse distance from one another and connected to one another, preferably via strut connections. Preferably, at least one first and one second strut cross are mounted on each of the first longitudinal scaffolding elements arranged at a transverse distance from one another. At least one of the first strut elements, preferably both first strut elements, of the first and second strut cross on the first longitudinal scaffolding elements arranged at a transverse distance are arranged in the shortened intermediate position, while the second strut elements of the first and second strut cross on the first longitudinal scaffolding elements arranged at a transverse distance are connected to the second longitudinal scaffolding elements of the second scaffolding component.Subsequently, the first strut elements arranged in the shortened intermediate position are extended and also connected to the second longitudinal scaffold elements.
[0020] In a preferred embodiment, the first scaffolding component is arranged in a lying state on a base, whereupon the second scaffolding component is lowered onto the second strut elements of the first and second strut cross using a lifting device, in particular a crane, and the second connection points of the second strut elements are connected to the second scaffolding component, preferably via the bolt connections, whereupon at least one of the first strut elements, preferably both first strut elements, are extended and connected to the second scaffolding component, preferably via the further bolt connections. Advantageously, the crane times can be minimized and the construction progress can be accelerated.
[0021] When assembling the supporting scaffold, the first scaffold component is laid down in a lying position, preferably essentially in a horizontal position, on the base, which can be the floor of a construction site or a support element laid on the ground, for example at least one squared timber. The second scaffold component is then lowered from above onto the first and second cross braces using the lifting gear. Since at least one of the first brace elements is arranged in the shortened intermediate position, the assembly of the second scaffold component on the first and second cross braces is made easier. Instead of four connections, initially only three or, if both first brace elements are arranged in the shortened intermediate position, only two connections need to be made between the second longitudinal scaffold element and the first and second cross braces.This significantly simplifies the difficult process of placing the second longitudinal scaffolding element onto the first and second cross braces. The at least one first brace element arranged in the shortened intermediate position can then be extended and connected to the second longitudinal scaffolding element, with the second longitudinal scaffolding element already in its final position of use relative to the first longitudinal scaffolding element. Of course, depending on requirements and length, any number of cross braces can serve as intermediate support for the second longitudinal scaffolding element.
[0022] According to the first alternative solution, the supporting scaffolding, which is in particular a preferably vertically towering scaffolding tower or a preferably horizontally extending scaffolding truss, has at least: a first scaffolding component with a first longitudinal scaffolding element and a second scaffolding component with a second longitudinal scaffolding element, a first strut cross, preferably a first diagonal cross, and a second strut cross, preferably a second diagonal cross, wherein the first and the second strut cross each have a first strut element and a second strut element which are connected to one another, wherein one ends of the first and the second strut elements are mounted on the first longitudinal scaffolding element of the first scaffolding component, wherein the other ends of the first and the second strut elements have first and second connection points, preferably first and second connection points.second connecting straps, which are each detachably mounted, preferably via bolt connections, on the second scaffold longitudinal element of the second scaffold component, wherein at least one of the first strut elements, preferably both first strut elements, in particular also the second strut elements, of the first and the second strut cross are adjustable in length, in particular telescopic.
[0023] 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.
[0024] The first and second connection points are preferably provided at the longitudinal ends of the first and second strut elements facing away from the first longitudinal scaffolding element. The first and second connection points preferably have connection openings, in particular through-openings extending transversely to the longitudinal direction of the respective first and second strut element. To form the bolt connections, connecting bolts are preferably arranged in the connection openings. As connecting bolts, locking bolts are preferably provided which completely penetrate the connecting openings designed as through-openings and corresponding through-openings on the second longitudinal scaffolding element. When mounted on the through-openings, the locking bolts can each be secured with a locking split pin to prevent them from being accidentally pulled out.
[0025] The first and second connecting openings are preferably provided on first and second connecting straps, respectively, which are located at the longitudinal ends of the first and second strut elements facing away from the first longitudinal scaffold element.
[0026] In order to enable different distances between the first and second longitudinal scaffolding elements, in a preferred embodiment the first and second strut elements of the first and second strut crosses are each connected to one another via a joint. Depending on the rotational position of the first to the second strut element about the joint, the transverse distance between the first and second longitudinal scaffolding elements, i.e. the distance perpendicular to the longitudinal axes of the first and second longitudinal scaffolding elements, can be adjusted. A second adjustment can be carried out for this purpose. Depending on the design, the fastening points for the strut crosses along the longitudinal scaffolding elements and / or the lengths of the strut crosses can be changed.
[0027] 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, with the joint connecting the central parts of two strut elements to one another. 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.
[0028] 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.
[0029] It is particularly preferred if the first and the second strut element of the first and the second strut cross are each arranged in the same plane perpendicular to the joint axis.
[0030] 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.
[0031] The assembly of the support scaffolding can be carried out particularly easily and safely if the first longitudinal end part and the second longitudinal end part are each telescopic relative to the central part.
[0032] In a preferred embodiment, the first and / or second connection points are formed by first and second connecting tabs, respectively.
[0033] Preferably, at least one of the first and second connecting tabs each has two connection openings for further struts.
[0034] The object of the invention can alternatively also be achieved with the following method for erecting a supporting scaffold: 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 one another and are connected to one another, and
[0035] Connecting stops, in particular retaining lugs, of the first and second strut triangles, preferably via retaining bolts, to the second scaffolding longitudinal element of the second scaffolding component.
[0036] When assembling the supporting scaffold, the second longitudinal scaffold element is connected to the stops of the first and second strut triangles. The first and second strut elements of the first and second strut triangles are each connected to one another in such a way that the second longitudinal scaffold element, when assembled, is arranged on the first and second strut triangles independently, i.e. in particular without the aid of lifting gear, in the specified position, in particular parallel to the first longitudinal scaffold element. In contrast to a connection via two individual struts, the first and second strut triangles form stable supports between the first and second longitudinal scaffold elements. The triangular shape means that the number of stops when assembling the second longitudinal scaffold element can be minimized, which can make handling much easier. Preferably, the first and second strut triangles each have only a single stop.
[0037] In a preferred embodiment, before or after the stops of the first and second strut triangles are connected to the second scaffolding longitudinal element of the second scaffolding component, at least one further strut is mounted on the first scaffolding longitudinal element of the first scaffolding component, which, after the stops of the first and second strut triangles are connected to the second scaffolding longitudinal element of the second scaffolding component, is connected to the second scaffolding longitudinal element.
[0038] In this embodiment, at least one further strut is mounted on the first longitudinal scaffolding element of the first scaffolding component, which further strut is connected to the second longitudinal scaffolding element of the second scaffolding component after the stops of the first and second strut triangles have been connected to the second longitudinal scaffolding element of the second scaffolding component. In this way, the assembly of the second scaffolding component can be made considerably easier. First, the second longitudinal scaffolding element is connected to the first and second strut triangles, which hold the second longitudinal scaffolding element at the predetermined, parallel distance from the first longitudinal scaffolding element. This is particularly advantageous if, as described above in connection with the first alternative solution, the second scaffolding component is lowered from above onto the first and second strut triangles using a lifting device, for example a crane.This requires precise handling of the second scaffolding 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 scaffolding element, in which an additional stop of the additional bracing for connection to the second longitudinal scaffolding element is arranged closer to the first longitudinal scaffolding element than the stops of the first and second strut triangles.
[0039] After connecting the stops of the first and second strut triangles with 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 with the second scaffold longitudinal element of the second scaffold component.
[0040] Depending on the design, the additional bracing can already be mounted on the first longitudinal scaffold element in the inactive position when the second scaffold component is lowered, in particular in a folded and / or shortened position. Alternatively, the additional bracing can only be mounted on the first longitudinal scaffold element in the inactive position after the stops of the first and second strut triangles have been connected to the second longitudinal scaffold element of the second scaffold component. As soon as the second scaffold component has been connected to the first and second strut triangles, the additional bracing can be moved from the inactive position into the active position, in particular folded out and / or extended, and connected to the second longitudinal scaffold element of the second scaffold component.
[0041] In a preferred embodiment, the first and / or second support struts of the first and / or second strut triangles are extendable, in particular telescopic, in order to adjust the transverse distance between the first and second longitudinal scaffold elements or to facilitate the installation process. Alternatively, the first and second support struts can be fixed in length.
[0042] In a preferred embodiment, the further bracing is constructed with a first and a second support strut corresponding to the first and second strut triangle.
[0043] In a first variant, the first support strut of the further bracing is first connected to the first longitudinal scaffolding element; the second support strut is detached from the fastening point at which the second support strut is connected to the first longitudinal scaffolding element in the active position. To connect it to the second longitudinal scaffolding element, the second support strut of the further bracing is unfolded and fastened to the fastening point on the first longitudinal scaffolding element. In a preferred variant, the first and / or the second support strut of the further bracing is extendable, in particular telescopic. In this embodiment, the further bracing can be brought into the active position by changing its length, in particular by telescoping.As a result, the additional stop of the further bracing is arranged at the level of the stops of the first and second strut triangles, at which the connection to the second longitudinal scaffolding element can be established, in particular via a bolt connection. If the first and / or the second support strut of the further bracing is extendable, in particular telescopic, alternatively the first and the second support strut of the further bracing can be attached in triangular form to the first longitudinal scaffolding element and brought into the active position by extension. With this variant, the unfolding of the further bracing can be omitted.
[0044] 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 ends of the first and second support struts are connected to the respective retaining tab and the other ends of the first and second support struts are mounted at a longitudinal distance from one another on the first scaffold longitudinal element of the first scaffold component.
[0045] The supporting scaffold, in particular scaffold tower or scaffold truss, of the second alternative solution according to the invention comprises at least: a first scaffold component with a first
[0046] Longitudinal scaffolding element and a second scaffolding component with a second longitudinal scaffolding element, wherein a first and a second strut triangle are mounted on the first longitudinal scaffolding element of the first scaffolding 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 one another and are connected to one another, wherein stops, in particular holding tabs, of the first and the second strut triangle are connected, preferably via holding bolts, to the second longitudinal scaffolding element of the second scaffolding component.
[0047] Preferably, the first and second support struts of the first and second strut triangles are connected to one another via the first and second retaining tabs, respectively.
[0048] The drawings illustrate exemplary embodiments of the invention.

[0057] Fig. 13 shows a strut triangle used in the supporting structure of Fig. 12. Figs. 1 to 3 show a first method for constructing a supporting structure 1 (cf. Fig. 3).
[0058] According to Fig. 1, a first scaffolding component 2 is arranged lying on a base, which can be a floor surface. The first scaffolding component 2 has at least one first longitudinal scaffolding element 3 which is elongated along a longitudinal axis. In the example shown, two first longitudinal scaffolding elements 3 are connected to one another via connecting flanges 4 such that the longitudinal axes of the first longitudinal scaffolding elements 3 are arranged in a line. Depending on the length of the supporting scaffold 1, any desired number of first longitudinal scaffolding elements 3 can be provided. For connection to one another, the first longitudinal scaffolding elements 3 can have connecting flanges 4 at their longitudinal ends. The first longitudinal scaffolding elements 3 each have holders 5 which are spaced apart from one another in the longitudinal direction and on which at least one first cross strut 6, here a first diagonal cross, and at least one second cross strut 7, preferably a second diagonal cross, are reversibly detachably mounted.In the example shown, further strut crosses 8 are mounted on the first longitudinal scaffolding elements 3 in a reversibly detachable manner. The first strut cross 6, the second strut cross 7 and the further strut crosses 8 are designed identically in the example shown. In the example shown, the first strut cross 6 and the second strut cross 7, and here also the further strut crosses 8, are connected to the holders 5 of the first longitudinal scaffolding elements 3 via bolt connections 19. The first strut cross 6, the second strut cross 7, and here also the further strut crosses 8, each have a first strut element 9 with a first connection point, here with a first connecting strap 10, and a second strut element 11 with a second connection point, in particular with a second connecting strap 12, at their free longitudinal ends.At least the first strut elements 9 of the first strut cross 6 and the second strut cross 7 are telescopic from a shortened intermediate position into an extended assembly position. In the example shown, the second strut elements 11 of the first strut cross 6 and the second strut cross 7, as well as the first strut elements 9 and the second strut elements 11 of the further strut cross 8, are also telescopic.
[0059] In the first step, the second strut elements 11 of the first strut cross 6 and of 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 strut cross 6 and of 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 straps 12, of the second strut elements 11 are essentially on the same plane, which is illustrated in Fig. 1 by a line 13. The other connection points of the other first 9 and second strut elements 11 are arranged closer to the first longitudinal scaffolding element 3, i.e. further down in the position shown.
[0060] In the second step, see Fig. 2, a second scaffolding component 14 with at least one second longitudinal scaffolding element 15, here with two second longitudinal scaffolding elements 15, is brought forward with the aid of a lifting device 16 which is only symbolically illustrated here. The second longitudinal scaffolding element 15 is identical to the first longitudinal scaffolding element 3; however, the lengths can be different depending on the design. The second scaffolding component 14 is lowered from above onto the level 13 of the second connection points of the first 6 and second strut cross 7. The first 6 and the second strut element 7 of the first 6 and the second strut cross 7 are each connected to one another via a joint 17 with a joint axis 18 (see Fig. 7 and Fig. 8 for details). As a result, the first 6 and the second strut cross 7 are positioned in the intermediate position in a fixed arrangement of the first 9 and second strut elements 11 to one another.
[0061] In the third step (cf. Fig. 3), the second connection points of the second strut elements 11 of the first 6 and second strut cross 7 are first connected, here via bolt connections 19, to the second longitudinal scaffolding elements 15 of the second scaffolding component 14. The remaining strut elements are still arranged in the 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 longitudinal scaffolding elements 15 are independently carried by the first 6 and second strut cross 7 via the bolt connections 19.The first strut elements 9, in the example shown also the first 9 and second strut elements 11 of the further strut crosses 8, are then telescoped from the shortened intermediate position into the extended assembly position, so that the corresponding connection points are arranged at the level of the plane 13. The first connection points of the first strut elements 9 of the first 6 and the second strut cross 7, in the example shown also the first and second connection points of the further strut crosses 8, can then be connected to the second scaffolding longitudinal elements 15 of the second scaffolding component 14, preferably likewise via bolt connections 19.
[0062] Fig. 4 and Fig. 5 show a variant of the assembly method illustrated in Figs. 1 to 3. In this variant, the first scaffolding component 2 has at least two first scaffolding longitudinal elements 3 arranged at a transverse distance, i.e. at a distance perpendicular to their longitudinal axes, to form a first scaffolding panel, which are connected to one another via strut connections 20 corresponding to the first strut cross 6 and second strut cross 7.
[0063] According to Fig. 4, the first scaffolding section is arranged lying down, here horizontally on a base, which can be a floor surface. First 6, second 7 and further cross braces 8 are arranged on the opposite first longitudinal scaffolding elements 3 in accordance with the embodiment of Figs. 1 to 4. The second connection points are arranged on the level 13 by telescoping the second brace elements 11 of the first 6 and second cross braces 7. The connection points of the remaining brace elements 9, 11 are positioned closer to the first longitudinal scaffolding elements 3 by telescoping into the shortened intermediate position, i.e. in the position shown below the level 13.
[0064] According to Fig. 5, the second scaffolding component 14 is brought forward with the lifting gear 16. In the embodiment of Fig. 4 and Fig. 5, the second scaffolding component 14 is designed as a second scaffolding plate corresponding to the first scaffolding component 2, which second scaffolding plate has second longitudinal scaffolding elements 15 arranged at a transverse distance from one another, which are connected to one another via further strut connections 21 corresponding to the first 6 and second strut cross 7. The second scaffolding component 14 is lowered to the level 13 and connected via the connections, in particular bolt connections, to the second connection points of the first 6 and second strut cross 7 arranged on the level 13. The remaining strut elements 9, 11 are then lengthened and connected to the second scaffolding component 14 in order to obtain the supporting scaffold 1.
[0065] Fig. 6 shows the support scaffold 1 in the assembled state. In the example shown, the support scaffold 1 is designed as a scaffold tower. For this purpose, the support scaffold 1 is brought from the lying position according to Fig. 5 into the vertically projecting position according to Fig. 6. However, the support scaffold 1 can also be arranged in the lying, in particular horizontal, state as a scaffold girder, also referred to as a scaffold girder. Formwork (not shown), in particular for the construction of bridges, can be mounted on the support scaffold 1.
[0066] Fig. 7 and Fig. 8 show the first strut cross 6 in detail, the other strut crosses being designed accordingly. In Fig. 7 and Fig. 8, the first strut cross 6 is shown in different angular positions of the first strut element 9 to the second strut element 11. The angular position can be adjusted by rotating about the joint 17. This makes it possible to achieve different transverse distances between the first 3 and second scaffolding longitudinal element 14. The first 9 and the second strut element 11 each have a first longitudinal end part 22, a second longitudinal end part 23 and a central part 24, the joint 17 connecting the central parts 24 of the first 9 and second strut element 11 to one another. The central part 24 of the second strut element 11 has a receiving opening 25 through which the central part 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 part 22 and the second longitudinal end part 23 are telescopic relative to the respective central part 24. With releasable fixings 26, here with securing bolts 27, the first 9 and the second strut element 11 can be fixed in various telescopic positions. In the example shown, the first 10 and the second connecting plate 12 are firmly connected to the first longitudinal end parts 22 of the first 9 and second strut element 11, respectively. In addition, further connecting plates 28 are provided on the second longitudinal end parts 23 for mounting on the first scaffolding component 2. The further connecting plates 28 are designed identically to the first 10 and second connecting plate 12, respectively.To form the bolt connection 19 with the first 3 or second longitudinal scaffold element 15, the first 10 and the second connecting plate 12, and here also the further connecting plates 28, in the example shown, each have a connection opening 29 in which a connecting bolt 30, in particular a locking bolt, can be arranged. Furthermore, the first 10 and the second connecting plate 12, and here also the further connecting plates 28, in the example shown, each have two connection openings 31 spaced from the connection opening 29 for connecting further struts (not shown) or for parking connecting bolts.
[0067] Figs. 9 to 11 show a second method for erecting the supporting structure 1 shown in Fig. 12. Only the differences from the previous embodiment will be discussed below.
[0068] According to Fig. 9, the first scaffolding component 2, which here has, for example, two first longitudinal scaffolding elements 3, is arranged lying down, in particular horizontally, on the base. A first 32 and a second strut triangle 33 are mounted on the first longitudinal scaffolding elements 3 of the first scaffolding component 2. The first 32 and the second strut 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, here essentially at right angles, to one another and are connected to one another in a stable triangular shape. The first 34 and the second support struts 35 are connected to one another at the converging end of the first 32 and second strut triangle 33 via stops, here holding tabs 36. The retaining tab 36 can be designed identically to the first connecting tab 10 in the previous embodiment.The opposite ends of the first 34 and second support strut 35 are connected to the first longitudinal scaffold elements 3 via further stops 37, spaced from one another in the direction of the longitudinal axis of the first scaffolding component 2. The holding tabs 36 each have a holding opening 38 corresponding to the connecting opening 29 in the previous exemplary embodiment. A holding bolt 42 (cf. Fig. 10) corresponding to the connecting bolt 30 in the previous exemplary embodiment can be inserted through the holding opening 38. In addition, the holding tabs 36 have two openings 39 spaced from the holding opening 38, wherein one of the openings 39 can be used to connect the second support strut 35 and the other of the openings 39 can be used to connect a further strut (not shown).
[0069] As further shown in Fig. 9, at least one further strut 40 is mounted on the first scaffold component 2. In the example shown, a further strut 40 is provided on each of the first scaffold longitudinal elements 3.
[0070] According to Fig. 9, the further strut 40 is mounted in a folded-in, inactive position on the first longitudinal scaffolding element 3. In the example shown, the further struts 40 are constructed corresponding to the first 32 and second strut triangle 33, wherein in the folded-in, inactive position of Fig. 9, the second support strut 35 is detached from the first longitudinal scaffolding element 3. According to Fig. 10, the second support strut 35 of the further strut 40 is folded out and fastened to the first longitudinal scaffolding element 3. The further strut 40 is still arranged in the inactive position, in which an additional stop 41, here a further holding lug, of the further strut 40 is arranged below the holding lugs 36 of the first 32 or second strut triangle 33.
[0071] In the next step, see Fig. 11, the second framework component 14 is first connected to the retaining tabs 36 of the first 32 and second strut triangle 33.
[0072] Subsequently, the further struts 40 are brought from the inactive position into the active position, in the embodiment shown by telescoping the first support strut 34 of the further strut 40.
[0073] As a result, the additional stop 41 of the further strut 40 is brought to the level of the stops of the first 32 and second strut triangle 33. Thus, the additional stop 41 of the further strut 40 can now be connected to the second scaffold longitudinal element 15, here with an additional retaining bolt 42.
[0074] In Fig . 12 the supporting scaffold 1 is shown , which is used here as a scaffold tower in vertical orientation .
[0075] Fig. 13 shows a modified embodiment of the first strut triangle 32, whereby the second strut triangle 33, and here also the additional struts 40, can be constructed accordingly. In this embodiment, the first 34 and the second support strut 35 are each designed to be non-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:
