Abstract

The invention relates to a supporting structure for a hall, stage, stand or bridge construction. It comprises a support structure (5) which is supported by two wall-like scaffold structures (1, 2), which support structure extends substantially in a horizontal plane and is shear-resistant in this plane. The two scaffold structures (1, 2), which each extend in vertical planes and are shear-resistant in these planes, are opposite one another at a distance apart. The support structure (5) extends between these scaffold structures (1, 2) and is connected to them in such a way that horizontal shear forces acting in the direction of the vertical planes of the scaffold structures (1, 2) can be transmitted from the support structure (5) to the scaffold structures (1, 2), but not bending moments which act around axes extending parallel to these planes. The supporting structure also comprises a wall-like further scaffold structure (3, 4) which extends in a vertical plane transversely to the two first-mentioned scaffold structures (1, 2) and is shear-resistant in this plane. The support structure (5) is connected to this further scaffold structure (3, 4) in such a way that horizontal shear forces which act in the direction of the vertical plane in which this further scaffold structure (3, 4) extends can be transmitted from the support structure (5) to this further scaffold structure (3, 4), but not bending moments which act around an axis extending parallel to this vertical plane. The invention makes it possible to combine the advantages of scaffolding and steel construction and to make available supporting structures for stormproof temporary hall, stage, stand or bridge constructions which, in spite of the use of scaffold walls, require little space for the structure and correspondingly make available a large amount of usable space.

Description

Supporting structure for a multiply erectable and degradable hall, stage, tribune or bridge construction

TECHNICAL AREA

The invention relates to support structures for a multiply constructed and dismantled hall, stage, tribune or bridge construction, a material set for forming such support structures, a support for such support structures, a material set for forming the support and a method for creating such support structures according to the Preambles of the independent claims.

STATE OF THE ART

Hall, stage, tribune or bridge constructions often represent temporary structures which are erected for a single occasion and then dismantled again.

It is of paramount importance that such structures are absolutely reliable under all conceivable operating conditions and loads and that they can be assembled and dismantled in the shortest possible time using as few assembly personnel as possible (often recruited locally). Also, the individual components from which such structures are created should be suitable for re-use in another similar structure, as possible to save space and have the lowest possible weight.

Today, two fundamentally different design principles are used to create hall, stage, grandstand or bridge constructions, namely scaffolding and steel construction.

Scaffolding has the advantage that space can be quickly filled with structure in manual assembly with small, standardized components and that due to the filigree structure, the floor load is low and no foundation is required. In addition, the Scaffolding offers great flexibility in terms of terrain and connection to adjacent structures and requires a small loading and storage volume. Another advantage is the high availability due to the use of standardized system components.

Another very important feature of the

Scaffolding is also that it is space-filling, which is particularly in the creation of hall buildings, which is about creating the largest possible enclosed space with the least possible structural volume, is disadvantageous and scaffolding therefore in spite of its advantages in many cases unsuitable or uneconomical makes for the construction of halls. This is because in a storm-proof design, the framework structures of the walls would have a thickness of several meters and would take up correspondingly much space.

In contrast to scaffolding, the steel construction allows large spans and generates a large volume of space with little structural volume. In principle, it is ideal for creating space-creating constructions, in particular for hall buildings, but has the disadvantage that it is inflexible, because each construction has to be individually planned and manufactured, a foundation is required and large machines are required for installation.

PRESENTATION OF THE INVENTION

It is therefore the task of providing technical solutions which do not have the aforementioned disadvantages of the prior art or at least partially avoid them.

This object is solved by the subject matters of the independent claims.

According to these, a first aspect of the invention relates to a support structure for a hall, stage, grandstand or bridge construction, which can be repeatedly assembled and disassembled or its components without further Reprocessing can be used multiple times for identical or similar structures. For this purpose, the support structure is made up of a large number of components which can be transported by land by means of normal transport vehicles (trucks) and are connected to one another by means of connections that can be made and detached in several ways.

The support structure has a wall-like first framework structure extending substantially in a vertical first plane and a wall-like second framework structure extending substantially in a vertical second plane. These framework structures face one another at a distance and thereby preferably run parallel to one another.

Weiner, the supporting structure ne at least egg, preferably exactly two wall-like additional Ge ^¬ rüststrukturen which is substantially in a vertical plane extending resp. extend transversely, preferably perpendicular to the first and the second plane in which extend the first and the second frame structure.

These wall-like framework structures are formed such that they are shear-resistant in the respective plane in which they extend. This is advantageously effected by means of diagonal braces extending parallel to the respective plane between the framework tubes of the framework structures.

Furthermore, the support structure has at least one support structure which extends substantially in a horizontal plane. This support structure is designed such that it is shear-resistant in this horizontal plane, which is preferably effected by diagonal struts running parallel to this plane.

This carrier structure or these carrier structures extends or extend between the first frame structure and the second frame structure and is or are connected to these two framework structures in such a way that they are supported by the first framework structure and the second framework structure.

In this case, the connections to the first and the second framework structure are each formed such that although horizontal thrust forces acting in the direction of the first plane in which the first framework structure extends, and which act in the direction of the second level, in which the second Frame structure extends, can be transmitted from the respective support structure on the first and the second frame structure, but not bending moments around parallel to the first and second plane extending axes around.

In this case, according to a first design variant according to the invention, the support structure or support structures is or are connected to the wall-like further framework structures in such a way that horizontal shear forces acting in the direction of the vertical planes in which these wall-like further framework structures extend are provided or the support structures can be transferred to the wall-like further framework structures, but not bending moments about parallel to these vertical planes extending axes around.

As an alternative or in addition to the embodiment of the support structure according to the first design variant mentioned in the aforementioned section, the support structure or support structures are or are connected to the first framework structure and the second framework structure in a second construction variant

Shearing forces acting in the direction of the vertical planes in which the wall-like further framework structures extend can be transmitted from the support structure or structures to the first and the second framework structure. Here are the first framework structure and the second framework structure is connected to the wall-like further framework structure in such a way that horizontal shear forces acting in the direction of the vertical planes in which these wall-like further framework structures extend extend from the first and the second framework structure to the wall-like further framework structures can be transmitted.

In other words, a first design variant of the support structure according to the first aspect of the invention relates to a supporting structure for a hall, stage, grandstand or bridge construction, which has a support structure supported by two wall-like framework structures, which extends substantially in a horizontal plane and shear-resistant in this plane. The two framework structures, which each extend in vertical planes and are shear-resistant in these planes, face each other at a distance. The support structure extends between and is connected to these framework structures such that horizontal shear forces acting in the direction of the vertical planes of the framework structures are transferable from the support structure to the framework structures, but not bending moments acting about axes parallel to these planes. Also, the support structure comprises a wall-like further framework structure which extends in a vertical plane transverse to the two first-mentioned framework structures and is shear-resistant in this plane. The support structure is connected to this further framework structure in such a way that horizontal pushing forces acting in the direction of the vertical plane in which this further framework structure extends can be transferred from the support structure to this further framework structure, but not bending moments which are around act parallel to this verti cal plane extending axis. In other words, a second design variant of the support structure according to the first aspect of the invention relates to a support structure for a hall, stage, grandstand or bridge construction, which has a supported by two wall-like framework structures support structure, which is substantially in a horizontal Plane extends and is shear-resistant in this plane. The two framework structures, which each extend in vertical planes and are shear-resistant in these planes, face each other at a distance. The support structure extends between and is connected to these framework structures so that in the direction of the vertical planes of the framework structures and transversely acting horizontal shear forces can be transmitted from the support structure to the framework structures, but not bending moments which are around axes parallel to these planes Act. Also, the support structure comprises a wall-like further framework structure which extends in a vertical plane transverse to the two first-mentioned framework structures and is shear-resistant in this plane. The aforementioned two framework structures, which carry the support structure, are connected to this further framework structure in such a way that horizontal pushing forces acting in the direction of the vertical plane in which this further framework structure extends extend from the framework structures supporting the support structure to the latter Framework structure are transferable.

The invention makes it possible to combine the advantages of scaffolding and steel construction and to provide supporting structures for storm-proof temporary halls, stages, grandstands or bridges which, despite the use of scaffolding walls, require little space for the structure and provide plenty of usable space. So can be with the Invention with commercially available framework material with framework wall thicknesses of 1 meter hall spans of up to 40 meters realize.

The at least one wall-like further framework structure is preferably arranged between the first framework structure and the second framework structure.

If exactly such a wall-like further framework structure is present, this is according to a first preferred embodiment of the support structure centrally disposed between the ends of the first and the second framework structure, so that the framework structures in plan view form an H-shaped floor plan. In this way, e.g. realize two mirror-image arranged covered stages with a common inventive support structure. According to a second preferred embodiment variant, this wall-like further framework structure is arranged at one end of the first framework structure and the second framework structure, so that the framework structures form a U-shaped ground plan in plan view. In this way, e.g. form a one-sided open hall construction with the inventive support structure.

If the support structure according to the invention has at least two wall-like further framework structures, namely a wall-like third framework structure which extends substantially in a vertical third plane, and a wall-like fourth framework structure which extends substantially in a vertical fourth plane, it is preferable to the third framework structure and the fourth framework structure are spaced apart, preferably such that the third level and the fourth level are substantially parallel to one another.

The third and the fourth framework structures are preferably arranged in each case at one end of the first and the second framework structure, and more preferably way such that these framework structures limit a rectangular space. In this way, for example, a circumferentially completely closed hall with the support structure according to the invention can be formed.

The wall-like further framework structures of the support structure according to the invention can be connected directly to the wall-like first framework structure and the wall-like second framework structure, or only indirectly via the support structure.

In a further preferred embodiment, the support structure according to the invention comprises a plurality, e.g. two, support structures, which are arranged one above the other at a distance from each other and formed as stated above and connected to the framework structures of the support structure. With such support structures, e.g. Create multi-storey hall or grandstand buildings.

The wall-like framework structures of the support structure advantageously have, in each case in the horizontal direction in the respective vertical plane in which they extend, an extension which is a multiple of their extent perpendicular to this plane. In this way, with little frame volume, a large converted volume of space can be made available.

The support structure of the inventive

The support structure preferably comprises a plurality of transversely extending, advantageously perpendicular to the vertical planes in which the first and the second frame structure extend extending carriers which extend at a distance from each other and preferably parallel to each other substantially in the horizontal direction and are connected to each other, For example, by vertical and diagonal to this extending struts that together form a shear-stiff structure in the horizontal direction. The carriers are preferably straight carrier and are preferably designed as trusses. In this case, it is preferred that the first and the second framework structure each have a multiplicity of vertical standpipe tubes and the carriers are each connected to these two framework structures in such a way that those of the carriers of the carrier structure in a vertical direction to the first and the second framework structure transmitted forces in each case substantially uniformly on four, seen in plan view an advantageously rectangular or square frame structure part forming framework tubes are transmitted. In this way, the carrying capacity of the framework structure can be utilized in the best possible way.

Further, it is preferred that pairs tube in each case those of Gerüststand- to a ^¬ line of the vertical forces in the four framework standpipes, which face each other in a direction transverse or perpendicular to the vertical plane in which the first and second Scaffold structure extends, carry a between these scaffolding stand pipes extending first support-support structure, which is preferably designed as a truss girder. These two first support support structures together support a second support support structure, eg in the form of a T-beam or double T-beam, extending between these first support support structures in a direction parallel to the vertical plane in which the extends first and the second frame structure. This second support support structure carries an end of the respective support of the support structure.

The location of introduction of the vertical forces from the carrier into the second support support structure is preferably below the locations of introduction of the vertical forces from the second support support structure into the first two support support structures. This results in a self-stabilizing force introduction situation. If the carrier is attached to the second support-support structure from below, which is likewise preferred, there is the advantage that it is pulled up for assembly by means of a chain or cable pull on the respective frame structure and against the second supports already mounted as intended Support structure can be attached without the need for a crane would be required.

Furthermore, it is advantageous for the first and the second framework structure to have a specific grid temperature with certain connecting elements (eg pin for connecting a further standpipe, perforated disk on the standpipe, wedge head to scaffold struts for fixing the struts to the perforated disk) and the first support structure. In this way, it becomes possible to integrate the first support support structures into a space frame with the first or the second framework structure, for example of this type in that the respective framework structure can be continued upwards using the first support support structures.

The supports are advantageously in the region of their ends via in each case exactly one bolt connection whose bolt longitudinal direction runs parallel to the respective vertical plane in which the first or the second framework structure extends, releasably connected to the first and the second framework structure or. connected to their second Auflager- support structures for the bending moment-free transmission of vertical forces on these scaffold structures.

It is further preferred that the neutral axis of the respective carrier extends substantially through the center of the respective bolt connection.

Furthermore, it is preferred that the carriers are each constructed from a plurality of components which are detachably interconnected with advantage via bolt connections, and advantageously from two head parts, which are preferably identical with respect to their structural geometry, and one or more arranged between these head ^¬ share, preferably identical carrier base elements. This results in the advantage that the carrier can be formed in different lengths of a few standardized components, which greatly simplifies the storage and provision.

If the carrier base elements are designed as two-dimensional frameworks, they require relatively little space during storage and transport. It is further preferred that the carrier base elements are connected to one another and to the head parts in each case via exactly two bolt connections.

Advantageously, the support base elements have a length of less than 5 m, e.g. a length of about 2 m or about 4 m, so that they are easy to transport and handle, e.g. by means of a normal forklift for Euro pallets.

In the carriers composed of two head parts and one or more support base elements arranged between these head parts, in which the head parts transfer the vertical forces respectively to the first and second framework structure via exactly one bolt connection, it is further preferred for the head carriers to be in the form of a triangular support structure are, in which at a first corner, the bolt connection for transmitting the vertical forces on the first or second frame structure is arranged and at the remaining two corners, the bolt connections are arranged for connection to the adjoining this headboard support base element. Such head parts allow ideal transfer of forces from the carrier base elements in the framework structure. Further, it is preferred that the head parts, with advantage on their upper side, each have a physicality for the coupling of a lifting device, such as a chain or cable pull, preferably an upwardly projecting tab with a mounting hole for such a lifting device. Advantageously, this corporeality is arranged in a region which lies between the carrier base element adjoining this head part and the location at which the head part transmits the vertical forces to the first or second framework structure. This results in the advantage that the carrier formed with such head parts can be pulled up for assembly by means of two chain or cable pulls in a well-defined position on the first and the second frame structure.

Furthermore, it is advantageous for the first and the second framework structure to have a specific grid temperature with specific connection elements (eg pin for connecting a further standpipe, perforated disk to the standpipe, wedge head to stand struts for fastening the struts to the perforated disks) and Carrier have the same fasteners with the same Rastersass or compatible with the grid size of the first and second framework structure grid size.

This makes it possible to integrate the carriers in a space frame with the first and the second framework structure, e.g. such that these framework structures can be continued using the carriers over the carriers.

Correspondingly, according to a further preferred embodiment of the support structure according to the invention, a space frame is arranged on the support structure, preferably the support structure of a grandstand or of a roof, in particular tilted on one or both sides, which preferably merges into the space structures of the first and second framework structures. A second aspect of the invention relates to a support for a support structure according to the first aspect of the invention. The carrier is formed from two head parts and one or more arranged between the head parts, preferably identical carrier basic elements, which are designed as two-dimensional trusses and are connected to each other and with the head parts in each case via exactly two bolt connections. Such carriers have the advantage that they require very little storage and transport in the disassembled state.

As already mentioned, the support base elements preferably have a length of less than 5 m, e.g. a length of about 2 m or about 4 m. So they are easy to transport and handle, e.g. by means of a simple forklift or under lowered chassis.

In a preferred embodiment, the head parts of the supports are each designed as a triangular support structure, which has in the region of a first corner a mating half of a bolt connection (eg a double lug) for transmitting the vertical forces to the first or second framework structure and in the region of the remaining two Corners has the bolt connections for connection to the carrier base element adjoining this head part. Such carriers enable ideal transfer of the forces from the carrier base elements into the bolt connections for transmitting the vertical forces to the first and the second frame structure.

In a further preferred embodiment of the carrier, the head parts each have on their top a physicality for coupling a lifting device, such as a chain or cable, on, preferably an upwardly projecting tab with a mounting hole for a lifting device. Advantageously, this corporeality is arranged in an area which lies between the adjoining head part of this support base member and the location at which the jewei ^¬ celled head part transmits the vertical forces when used according to the first and second backbone structure. This has the advantage that the carrier for mounting using two chain or

Cables can be pulled in a well-defined position on the first and the second frame structure.

A third aspect of the invention relates to a material set for forming a carrier according to the second aspect of the invention. The material set comprises two head parts and at least one carrier base element which can be connected via bolt connections to the head parts to form a carrier according to the invention.

A fourth aspect of the invention relates to a material set for forming a support structure according to the first aspect of the invention. The material set comprises framework material for creating the first framework structure and the second framework structure as space frameworks with certain connection elements with a certain grid dimension. Furthermore, the material set comprises material for forming the carrier structure in such a way that this carrier structure has a plurality of carriers which have the same connection elements with the same grid size or a grid dimension compatible with the grid size of the first stand structure and the second stand structure, so that the carriers are in a space frame the first framework structure and the second framework structure can be integrated.

Such material sets represent preferred forms of commerce of the invention.

A fifth aspect of the invention relates to a

Method for creating a support structure, preferably a support structure according to the first aspect of the invention.

According to the method, a wall-like first framework structure which extends substantially in a vertical first plane and shear-resistant this plane is, and a wall-like second framework structure, which extends substantially in a vertical, preferably parallel to the first plane extending second plane and is shear-stiff in this plane, provided such that they face each other with a distance.

Furthermore, a support structure comprising at least two supports is provided, which extends substantially in a horizontal plane, preferably near the bottom or at the bottom, between the first stand structure and the second stand structure and is shear-resistant in this plane. The support structure penetrates with the ends of their carrier into the first and in the second framework structure.

Both between the first framework structure and the carriers of the carrier structure in the region or near the region in which the ends of the carriers penetrate into the first framework structure, as well as between the second framework structure and the carriers of the carrier structure in the region or near the region which the ends of the carrier penetrate into the second framework structure, lifting devices, preferably cable or chain hoists, are arranged.

Then, the support structure by means of the lifting devices under a vertical process of the ends of the carrier within the first and the second

Scaffold structure raised until it is in a desired installation position between the first and the second framework structure.

In this installation position, the ends of the carriers of the carrier structure are connected to the first frame structure and the second frame structure in such a way that the carrier structure is carried by the first and the second frame structure during removal or unloading of the lifting devices and indeed in the direction of the first or the second frame structure second plane acting horizontal thrust forces from the support structure to the first and second framework structure can be transmitted, but not bending moments, which act around parallel to the first and second plane extending axes.

With the method according to the invention, it is also possible to create supporting structures according to the first aspect of the invention with large spans without a crane.

In a preferred embodiment of the method, the carriers of the carrier structure are formed with one or more carrier base elements, which are connected to one another, wherein the carrier base elements are driven during installation of the carrier to provide the support structure by means of underlying chassis in the desired mounting position, which preferably done by muscle power.

Preferably, four uses height-adjustable trolleys whose height is set during assembly.

In this way are tools such as fork ^¬ stapler, which required a lot of space loading in the assembly area and a source of danger for the assembly personnel, only for unloading the carrier primitives from the truck needed during the transport of the same at the spot and the positioning and alignment essentially without machine assistance.

WAYS FOR CARRYING OUT THE INVENTION

Fig. 1 shows a side view of a first inventive support structure for a temporary rectangular hall construction. Fig. 2 shows a top view of this support structure. When the hall construction is completed, this support structure is covered on all sides with tarpaulins or other fabrics.

As can be seen, the support structure comprises two scaffold walls 1, 2 (claim-compliant wall-like first and second scaffold structures) extending parallel to each other and extending in vertical planes, which support a roof support structure 5 (claimed support structure) extending in a horizontal direction Level extending between them.

The scaffold walls 1, 2 are constructed of conventional framework material, ie of scaffolding elements with Stand scaffold tubes 7 with perforated discs 11 and end pinning 12 for connecting other scaffolding elements, which are connected to each other with horizontal wedge 21 (bar) and diagonal struts 10 which are each attached with end wedge heads on the perforated discs 11, and one in the vertical plane of his Stretching to form shear-resistant space frame.

The roof support structure 5 comprises a plurality of perpendicular to the scaffold walls 1, 2 extending support 6, which extend parallel to each other at a distance from each other in the horizontal direction and are connected by diagonal struts 18 and other struts 24 to a shear-resistant structure in the horizontal direction.

As can be seen from FIGS. 5a and 5b, which show a side view of one of the carriers 6 (FIG. 5a) and a top view of one of the carriers (FIG. 5b), the carriers 6 are straight trusses 6, which are formed from two head parts 14 and four identical, arranged between the head parts 14 support base elements 15. In this case, both the carrier base elements 15 and the head parts 14 are formed as two-dimensional frameworks and connected to each other in each case via exactly two bolt connections 13.

As can also be seen in particular from FIG. 8, which shows an enlarged perspective top view of a partially mounted carrier 6, the head parts 14 have on their upper side an upwardly projecting lug 16 with a fastening bore for a chain or cable 17. This tab 16 is arranged in a region of the head part 14 which lies between the support base element 15 adjoining this head part 14 and the bolt connection 13, via which the head part 14 transmits the vertical forces to the framework wall 1. The carrier base elements 15 have the same connecting elements 11, 12 with the same grid size as the Scaffolding wall 1 or with a grid size compatible with the grid size of the scaffold wall.

As can be seen in conjunction with Figures 6 and 7, which shows a side view of the region of the connection of one end of the carrier 6 to the left frame wall 1 (FIG. 6) and an enlarged perspekti ^¬ vische top view of this area before insertion of the bolt 13a for producing the bolt connection 13 (FIG. 7), the head parts 14 transmit the vertical forces via exactly one bolt connection 13 to the scaffold walls 1, 2. The bolt longitudinal direction of this bolt connection 13 runs parallel to the vertical planes in which the scaffold walls 1, 2 extend (suitably first and second plane), so that this bolt connection can not transmit bending moments, which act around axes parallel to these planes.

In this case, the head parts 14 are each formed as a triangular support structure, on whose side facing away from the carrier 6 (claim first corner) a double lug 19 (claim mating half of a bolt connection) is arranged. This forms together with a counter-tab on the framework wall 1 and the bolt 13 a, the bolt connection 13 with the framework wall 1. The center of this bolt connection 13 and the bolt 13 a lies in the neutral axis of the carrier 6. At the other two corners of the triangular support structure of the head part 14, the bolt connections 13 are arranged to the support element 15 adjoining this head part 14.

As can be further seen in particular in FIG. 7, the introduction of the forces transmitted from the bolt 13a in the vertical direction to the framework wall 1 takes place in each case substantially uniformly on four scaffolding tubes 7 forming a quadratic framework structural part as seen in plan view the cooperating with the bolt 13 a counter-tab of a double-T-carrier 9 (claim second Supporting support structure) which transfers the vertical forces in half to two truss girders 8 (demanding first support girder structures), which in turn distribute these forces in half to two opposing truss standpipes 7. In this case, the carrier 6 is attached to the double-T-carrier 9 from below, and the location of the introduction of the vertical forces from the double lug 19 of the head part 14 of the carrier 6 into the opposite lug of the double-T carrier 9 is below that Places the initiation of the vertical forces of the double-T-beam 9 in the two truss 8. Here, the two trusses 8 have the same fasteners 11, 12 with the same grid size as the scaffold wall 1 and are integrated into the space frame.

As is apparent from Fig. 2, the roof support structure 5 is also connected via diagonal braces 22 and other braces 23 in such a manner with the two framework ^¬ walls 1, 2, that horizontal shear forces acting in the direction of the vertical planes in which this Scaffolding walls 1, 2 extend, of the roof support structure 5 on these scaffold walls 1, 2 are transferable, but not bending moments, which act around parallel to these planes extending axes around.

Furthermore, the support structure comprises two further scaffold walls 3, 4 extending parallel to one another and extending in each case in vertical planes (claim-compliant wall-like further scaffold structures or third and fourth scaffold structures as claimed), which exert no supporting function with respect to the roof support structure 5.

This further scaffold walls 3, 4 are at an angle of 90 ⁰ (perpendicular) to the frame walls 1, 2 which carry the roof support structure 5, and as this made up of conventional scaffolding material, ie from scaffolding elements with scaffold stand pipes 7 with perforated discs 11 and end spinning 12 for Ansohliessen further scaffolding elements, which over horizontal Struts 21 (bars) and diagonal struts 10, which are each secured with end wedge heads on the perforated discs 11, are interconnected. They also form one in the vertical plane of his

Extension of shear-resistant space frame. These others

Scaffolding walls 3, 4 are not connected to the scaffold walls 1, 2, which carry the roof support structure 5.

2, the roof support structure 5 is also connected to these scaffold walls 3, 4 via diagonal struts 22, such that horizontal thrust forces acting in the direction of the vertical planes in which these scaffold walls 3, 4 extend , of the roof support structure 5 on these scaffold ^¬ walls 3, 4 are transferable, but not bending moments, which act around parallel to these planes extending axes around.

The second inventive support structure shown in FIGS. 3 and 4 differs from the support structure described above only in that the further scaffold walls 3, 4 are connected to the scaffold walls 1, 2, which support the roof support structure 5, such that horizontal shear forces, which act in the direction of the vertical planes, in which the further framework walls 3, 4 extend, from which the roof support structure 5 supporting scaffold walls 1, 2 on the other scaffold walls 3, 4 can transmit v / earth.

FIGS. 9 and 10 show plan views from above of the support structures according to FIGS. 1 and 2 {FIG. 9) and according to FIGS. 3 and 4 (FIG. 10) in the unfinished state during assembly according to the method according to the invention.

These top views show the scaffold walls 1, 2, 3, 4 (suitably arranged first and second scaffold structure and according to the requirements at least one further scaffold structure or third and fourth scaffold structure) provided at the intended location and, arranged on the Floor between these, the roof support structure 5 formed from the supports 6 and the arranged between these struts 18, 24 (claim support structure).

As can be seen, the roof support structure 5 with the ends of its supports 6 penetrates into the framework walls 1, 2, which are provided for supporting the roof support structure 5.

In order to provide the carriers 6 of the roof support structure 5 and to position them for the overall assembly of the roof support structure 5, the carrier base elements 15 were placed on height adjustable carriages 20 immediately after being unloaded by the transport vehicle, moved by the assembly personnel by hand to the desired mounting position, adjusted in height and then connected with each other and with the head parts 14 to the respective carriers 6, as shown in Fig. 8.
