Description

The invention relates to a method for constructing a supporting structure.

Furthermore, the invention relates to a supporting scaffold, in particular a scaffold tower or a scaffold truss.

Support or shoring scaffolding is 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. In order 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 A structural system of this kind is known, with elongated beams, to which connectors can be mounted using bolts. Struts can be connected to the connectors.

However, the disadvantage is the difficult assembly of such support structures with elongated longitudinal beams, which are usually brought in with a hoist, in particular a crane, and connected to one another via individual struts. The individual struts must 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 must 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, shape-invariant 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 must be aligned at a large number of connection points of such a strut structure at the same time. This requires precise handling of the second longitudinal beam, which requires trained personnel and involves considerable time expenditure. In addition, the connection points must have comparatively large tolerances, which reduce the load-bearing capacity when assembled.

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 has the particular aim of simplifying the assembly of a supporting structure made of longitudinal scaffolding elements via strut elements without impairing the load-bearing capacity of the resulting supporting structure.

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.

• Vorsehen einer ersten Gerüstkomponente mit einem ersten Gerüstlängselement und einer zweiten Gerüstkomponente mit einem zweiten Gerüstlängselement, wobei am ersten Gerüstlängselement der ersten Gerüstkomponente ein erstes Strebenkreuz, vorzugsweise ein erstes Diagonalkreuz, und ein zweites Strebenkreuz, vorzugsweise ein zweites Diagonalkreuz, montiert sind, wobei das erste und das zweite Strebenkreuz jeweils ein erstes Strebenelement mit einer ersten Verbindungsstelle, insbesondere mit einer ersten Verbindungslasche, und ein zweites Strebenelement mit einer zweiten Verbindungsstelle, insbesondere mit einer zweiten Verbindungslasche, aufweisen, wobei zumindest eines der ersten Strebenelemente, vorzugsweise beide erste Strebenelemente, insbesondere zudem die zweiten Strebenelemente, des ersten und des zweiten Strebenkreuzes von einer verkürzten Zwischenstellung in eine verlängerte Montagestellung verlängerbar, insbesondere teleskopierbar, sind,
• Anordnen zumindest eines der ersten Strebenelemente, vorzugsweise beider erster Strebenelemente, des ersten und des zweiten Strebenkreuzes in der verkürzten Zwischenstellung,
• Verbinden der zweiten Verbindungsstellen der zweiten Strebenelemente des ersten und des zweiten Strebenkreuzes, vorzugsweise über Bolzenverbindungen, mit dem zweiten Gerüstlängselement der zweiten Gerüstkomponente,
• Verlängern des ersten Strebenelements, vorzugsweise beider erster Strebenelemente, von der verkürzten Zwischenstellung in die verlängerte Montagestellung, und
• Verbinden der ersten Verbindungsstelle des ersten Strebenelements, vorzugsweise beider erster Strebenelemente des ersten und des zweiten Strebenkreuzes, vorzugsweise über weitere Bolzenverbindungen, mit dem zweiten Gerüstlängselement der zweiten Gerüstkomponente.

In the procedure for erecting the supporting structure of the first alternative, at least the following steps are carried out:

• 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 strut cross, preferably a first diagonal cross, and a second strut 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 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 can be extended, in particular telescopic, from a shortened intermediate position to an extended assembly position,
• Arranging at least one of the first strut elements, preferably both first strut elements, of the first and the second strut cross in the shortened intermediate position,
• Connecting the second connection points of the second strut elements of the first and second strut crosses, preferably via bolt connections, to the second scaffold longitudinal element of the second scaffold component,
• Extending the first strut element, preferably both first strut elements, from the shortened intermediate position to the extended assembly position, and
• Connecting the first connection point of the first strut element, preferably both first strut elements of the first and second strut crosses, preferably via further bolt connections, to the second scaffold longitudinal element of the second scaffold component.

This method can significantly simplify the construction of the support scaffold. To connect the second scaffold component 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 detachably connected to the corresponding connection points of the second scaffold longitudinal 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 scaffold longitudinal element than the second connection points of the first and second strut crosses. When arranging the second scaffold longitudinal element, therefore, only the connections to the second strut elements must first be made, whereas at least one of the first strut elements is only connected to the second scaffold longitudinal element in the next step after it has been extended, in particular telescoped, into the extended assembly position. This makes handling the second scaffold longitudinal element during assembly much easier, since a smaller number of connection points have to be aligned with one another in the same step. If the first and second strut crosses were constructed from strut elements of fixed length, all strut elements would have to be positioned at the corresponding connection points of the second longitudinal scaffold element. This would place high demands on the handling of the second longitudinal scaffold element. With the method according to the invention, the second longitudinal scaffold element can be assembled much 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 scaffold element is held independently in the final assembly position on the first and second strut crosses in the intermediate position of the at least one first strut element. The second longitudinal scaffold element is thus already held in position in relation 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 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 scaffold element can be kept low. This has a beneficial effect on the stability and load-bearing capacity of the support scaffold.

In the state of the art (cf. CN111005543A and CN 208363546 U ) support structures with telescopic connecting elements are known, but these are only used for the remote purpose of changing the horizontal distance between vertical supports. Apart from the different objectives, the known designs would also be structurally unsuitable for carrying out the method according to the invention.

The extendible strut elements, i.e. the first strut elements and preferably also the second strut elements, preferably have releasable fixations 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 other positions.

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 that 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 scaffold element before at least one of the first strut elements is brought 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 designed to be fixed in length and only at least one of the first strut elements is designed to be telescopic.

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.

In one embodiment, the first scaffolding component has a single first scaffolding longitudinal element or a plurality of first scaffolding longitudinal elements arranged in a line, which are connected via the first and second strut crosses to a single second scaffolding longitudinal element or a plurality of second scaffolding longitudinal elements of the second scaffolding component arranged in a line. In addition to the first and second strut crosses, further strut crosses can be provided.

In a further embodiment, the first and second scaffold components are designed as a first and second scaffold panel with at least two first and second scaffold longitudinal elements arranged at a transverse distance from one another and connected to one another, preferably via strut connections. Preferably, the first and second scaffold longitudinal elements are arranged at a transverse distance from one another and connected to one another, preferably via strut connections. At least one first and one second strut cross are mounted on each of the first longitudinal scaffolding elements arranged at a 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. The first strut elements arranged in the shortened intermediate position are then lengthened and also connected to the second longitudinal scaffolding elements.

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 crosses using a hoist, 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 construction progress accelerated.

When assembling the support scaffold, the first scaffold component is laid down in a lying position, preferably essentially horizontally, on the base, which can be the floor of a construction site or a support element laid on the floor, 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 hoist. Since at least one of the first cross 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, only three or, if both first cross 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 can significantly simplify the difficult process of placing the second longitudinal scaffold element on the first and second cross braces. Then the at least one first strut element arranged in the shortened intermediate position can be extended and connected to the second longitudinal scaffold element, whereby the second longitudinal scaffold element is already in the final position of use relative to the first longitudinal scaffold element. Of course, depending on the requirements and length, any number of strut crosses can serve as intermediate support for the second longitudinal scaffold element.

• ein erstes Strebenkreuz, vorzugsweise ein erstes Diagonalkreuz, und ein zweites Strebenkreuz, vorzugsweise ein zweites Diagonalkreuz,
• wobei das erste und das zweite Strebenkreuz jeweils ein erstes Strebenelement und ein zweites Strebenelement aufweisen, die miteinander verbunden sind,
• wobei die einen Enden der ersten und der zweiten Strebenelemente am ersten Gerüstlängselement der ersten Gerüstkomponente montiert sind,

• wobei zumindest eines der ersten Strebenelemente, vorzugsweise beide erste Strebenelemente, insbesondere zudem die zweiten Strebenelemente, des ersten und des zweiten Strebenkreuzes längenverstellbar, insbesondere teleskopierbar, sind.

According to the first alternative solution, the supporting scaffold, which is in particular a preferably vertically towering scaffold tower or a preferably horizontally extending scaffold truss, has at least:

• a first scaffold component with a first scaffold longitudinal element and a second scaffold component with a second scaffold longitudinal element,
• a first strut cross, preferably a first diagonal cross, and a second strut cross, preferably a second diagonal cross,
• wherein the first and second strut crosses each have a first strut element and a second strut element which are connected to one another,
• wherein one ends of the first and second strut elements are mounted on the first scaffold longitudinal element of the first scaffold component,
• wherein the other ends of the first and second strut elements have first and second connection points, preferably first and second connection straps, respectively, 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.

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

Preferably, the first and second connection points are provided at the longitudinal ends of the first and second strut elements facing away from the first longitudinal scaffold 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 connecting openings. The connecting bolts are preferably locking bolts, which completely penetrate the connecting openings designed as through-openings and corresponding through-openings on the second longitudinal scaffold element. When mounted on the through-openings, the locking bolts can each be secured with a safety pin to prevent them from being accidentally pulled out.

The first and second connection 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.

In order to allow 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 one another via a joint. Depending on the rotational position of the first to the second strut element around the joint, 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 carried out for this. Depending on the design, the fastening points for the strut crosses along the longitudinal scaffold elements and/or the lengths of the strut crosses can be changed.

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 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.

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.

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.

The assembly of the supporting structure 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.

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

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

• Vorsehen einer ersten Gerüstkomponente mit einem ersten Gerüstlängselement und einer zweiten Gerüstkomponente mit einem zweiten Gerüstlängselement, wobei am ersten Gerüstlängselement der ersten Gerüstkomponente ein erstes und ein zweites Strebendreieck montiert sind, wobei das erste und das zweite Strebendreieck jeweils eine erste und eine zweite Stützstrebe aufweisen, die winkelig zueinander angeordnet und miteinander verbunden sind, und
• Verbinden von Haltestellen, insbesondere Haltelaschen, des ersten und des zweiten Strebendreiecks, vorzugsweise über Haltebolzen, mit dem zweiten Gerüstlängselement der zweiten Gerüstkomponente.

The object of the invention can alternatively be achieved with the following method for constructing a supporting structure:

• 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
• Connecting stops, in particular retaining tabs, of the first and second strut triangles, preferably via retaining bolts, to the second scaffold longitudinal element of the second scaffold component.

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 a lifting device, in the specified position, in particular parallel to the first longitudinal scaffold element. In contrast to the 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.

In a preferred embodiment, before or after connecting the stops of the first and second strut triangles to 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 to the second scaffold longitudinal element of the second scaffold component, is connected to the second scaffold longitudinal element.

In this embodiment, the at least one further strut is mounted on the first longitudinal scaffold element of the first scaffold component, which is connected to the second longitudinal scaffold element of the second scaffold component after the stops of the first and second strut triangles have been connected to the second longitudinal scaffold element of the second scaffold component. In this way, the assembly of the second scaffold component can be made significantly easier. First, the second longitudinal scaffold element is connected to the first and second strut triangles, which hold the second longitudinal scaffold element at the predetermined, parallel distance from the first longitudinal scaffold element. This is particularly advantageous if, as described above in connection with the first alternative solution, the second scaffold 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 scaffold component, which is made more difficult by each additional connection point. In a preferred embodiment, the further bracing is initially arranged in an inactive position on the first longitudinal scaffold element, in which an additional stop of the further bracing for connection to the second longitudinal scaffold element is arranged closer to the first longitudinal scaffold element than the stops of the first and second strut triangles.

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

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 further strut can be brought from the inactive position into the active position, in particular unfolded and/or extended, and connected to the second scaffold longitudinal element of the second scaffold component.

In a preferred embodiment, the first and/or the second support strut of the first and/or the second strut triangle can be extended, in particular telescopic, in order to be able to adjust the transverse distance between the first and the second longitudinal scaffold element or to facilitate the installation process. Alternatively, the first and the second support strut can be fixed in length.

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.

In a first variant, the first support strut of the additional strut 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 additional strut 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 additional strut is extendable, in particular telescopic. In this embodiment, the additional strut can be brought into the active position by changing its length, in particular by telescoping. As a result, the additional stop of the additional strut 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 additional bracing is extendable, in particular telescopic, the first and the second support strut of the additional bracing can alternatively be attached in a triangular shape to the first longitudinal scaffold element and brought into the active position by extending them. With this variant, the additional bracing does not need to be unfolded.

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.

In the 1 to 3 is a first method for constructing a supporting structure 1 (cf. 3 ) is shown.

According to 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 that 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 number of first longitudinal scaffolding elements 3 can be provided. To connect them 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 brackets 5 that are spaced apart from one another in the longitudinal direction and on which at least one first strut cross 6, here a first diagonal cross, and at least one second strut cross 7, preferably a second diagonal cross, are reversibly detachably mounted. In the example shown, further strut crosses 8 are mounted on the first longitudinal scaffold elements 3 in a reversibly detachable manner. The first strut cross 6, the second strut cross 7 and the further strut crosses 8 are identical in the example shown. In the example shown, the first 6 and the second strut cross 7, here also the further strut crosses 8, are connected to the brackets 5 of the first longitudinal scaffold elements 3 via bolt connections 19. The first strut cross 6, the second strut cross 7, 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, each at their free longitudinal ends. At least At least the first strut elements 9 of the first 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 6 and the second strut cross 7, as well as the first 9 and the second strut elements 11 of the other strut crosses 8, are also telescopic.

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, 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 connection tabs 12, of the second strut elements 11 are essentially on the same level as in 1 is illustrated by a line 13. The remaining connection points of the remaining first 9 and second strut elements 11 are arranged closer to the first longitudinal scaffold element 3, i.e. further down in the position shown.

In the second step, cf. 2 , a second scaffold component 14 with at least one second scaffold longitudinal element 15, here with two second scaffold longitudinal elements 15, is brought in with the help of a lifting device 16, which is only symbolically illustrated here. The second scaffold longitudinal element 15 is designed identically to the first scaffold longitudinal element 3; however, the lengths can be different depending on the design. The second scaffold component 14 is lowered from above to 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 via a joint 17 to a joint axis 18 (see in detail 7 and 8th ) are connected to one another. 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.

In the third step, cf. 3 , first the second connection points of the second strut elements 11 of the first 6 and second strut cross 7 are 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 supported by the first 6 and second strut cross 7 via the bolt connections 19. The first strut elements 9, and in the example shown also the first 9 and second strut elements 11 of the other 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 height of level 13. Thereafter, 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, preferably also via bolt connections 19, can be connected to the second scaffold longitudinal elements 15 of the second scaffold component 14.

4 and 5 show a variant of the 1 to 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, ie at a distance perpendicular to their longitudinal axes, for forming a first scaffold panel, which are connected to one another via strut connections 20 corresponding to the first 6 and second strut cross 7.

According to 4 The first scaffolding plate is arranged horizontally on a base, which can be a floor surface. On the opposite first scaffolding longitudinal elements 3, first 6, second 7 and further cross braces 8 are respectively arranged according to the embodiment of the 1 to 4 The second connection points are arranged on the level 13 by telescoping the second strut elements 11 of the first 6 and second strut crosses 7. The connection points of the remaining strut elements 9, 11 are positioned closer to the first longitudinal scaffold elements 3 by telescoping into the shortened intermediate position, ie in the position shown below the level 13.

According to 5 the second scaffold component 14 is brought in with the hoist 16. The second scaffold component 14 is in the embodiment of the 4 and 5 corresponding to the first scaffold component 2, is designed as a second scaffold disc, which has second scaffold longitudinal 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 scaffold 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 arranged on the level 13. and second strut crosses 7. The remaining strut elements 9, 11 are then extended and connected to the second scaffolding component 14 to obtain the supporting scaffolding 1.

For this purpose, the supporting scaffold 1 is moved from the lying position according to 5 in the vertically raised position according to 6 However, the supporting structure 1 can also be arranged in a lying, in particular horizontal, state as a scaffold truss, also referred to as a scaffold truss. A formwork (not shown), in particular for the construction of bridges, can be mounted on the supporting structure 1.

7 and 8th show in detail the first strut cross 6, whereby the other strut crosses are designed accordingly. In 7 and 8th 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, with 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 detachable fixations 26, here with locking 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 strap 12 are firmly connected to the first longitudinal end parts 22 of the first 9 or second strut element 11. In addition, further connecting straps 28 are provided on the second longitudinal end parts 23 for mounting on the first scaffold component 2. The further connecting straps 28 are designed identically to the first 10 or second connecting strap 12. To form the bolt connection 19 with the first 3 or second scaffold longitudinal element 15, the first 10 and the second connecting strap 12, here also the further connecting straps 28, in the example shown each have a connection opening 29 in each of which a connecting bolt 30, in particular a locking bolt, can be arranged. In addition, the first 10 and the second connecting strap 12, here also the further connecting straps 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.

In the 9 to 11 is a second method for building the 12 shown supporting structure 1. Only the differences to the previous version are discussed below.

According to 9 the first scaffolding component 2, which here has, for example, two first longitudinal scaffolding elements 3, is arranged lying, 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 a right angle, 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 holding 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 spaced apart in the direction of the longitudinal axis of the first scaffold component 2 and are connected to the first longitudinal scaffold elements 3 via further stops 37. The retaining tabs 36 each have a retaining opening 38 corresponding to the connection opening 29 in the previous embodiment. A retaining bolt 42 (cf. 10 ) corresponding to the connecting bolt 30 in the previous embodiment. In addition, the retaining tabs 36 have two openings 39 spaced apart from the retaining 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).

As from 9 As can also be seen, 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.

According to 9 the further strut 40 is mounted in a folded inactive position on the first longitudinal scaffold element 3. In the example shown play, the other struts 40 are constructed according to the first 32 and second strut triangle 33, whereby in the folded inactive position of the 9 the second support strut 35 is detached from the first longitudinal scaffold element 3.

According to 10 the second support strut 35 of the further strut 40 is unfolded and fastened to the first longitudinal scaffold element 3. The further strut 40 is still arranged in the inactive position, in which an additional stop 41, here a further retaining tab, of the further strut 40 is arranged below the retaining tabs 36 of the first 32 or second strut triangle 33.

In the next step, see 11 , the second scaffold component 14 is first connected to the retaining tabs 36 of the first 32 and second strut triangle 33.

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.

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. The additional stop 41 of the further strut 40 can now be connected to the second longitudinal scaffold element 15, here with a further retaining bolt 42.

In 12 the supporting scaffold 1 is shown, which is used here as a scaffold tower in vertical orientation.

13 shows a modified embodiment of the first strut triangle 32, whereby 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 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.
