Description

[0001] The invention relates to a scaffold connection device for an air-supported roof. Furthermore, the invention relates to a scaffold with a scaffold connection device according to the invention, and to a method for manufacturing a scaffold with an air-supported roof using a scaffold connection device according to the invention. In addition, a use for an air-supported roof is proposed.

[0002] Scaffolding with weather protection roofs is a known feature of modern technology. The purpose of these roofs is to protect the scaffolding and / or the construction site from the elements. This improves workplace safety and the quality of work, as rain or snow falling on scaffolding platforms poses a significant safety risk when working on the scaffold.

[0003] A weather protection roof for scaffolding typically consists of a supporting structure made of aluminum or steel profiles and a tarpaulin covering this structure, such as a keder tarpaulin. The supporting structure requires a significant amount of material, especially for large spans, so erecting a weather protection roof is usually quite expensive. Another disadvantage is that snow can accumulate on the roof and then has to be removed manually. This poses a risk of falls for the person performing this task.

[0004] Air-supported roofs are also known from the prior art, for example as covers for gas storage tanks. These generally consist of a double membrane enclosing a volume of air under positive pressure. A supporting structure is therefore often unnecessary.

[0005] The present invention is concerned with the objective of increasing occupational safety on scaffolding and / or a scaffolded construction site by means of a weather protection roof, which in particular requires little material.

[0006] To solve the problem, the following are proposed: the scaffold connection device, in particular for a weather protection roof, preferably an air-supported roof, with the features of claim 1; the scaffold with the features of claim 5; and the method with the features of claim 13. Advantageous embodiments of the invention are described in the respective dependent claims. Furthermore, use for an air-supported roof according to claim 15 is specified. Disclosure of the invention

[0007] A scaffold connection device for an air-supported roof is proposed. The scaffold connection device features: a frame construction composed of profiles for the preferably circumferential, clamping and / or locking reception and / or airtight connection of at least one membrane of the air-supported roof, as well as several scaffold brackets connected to the frame construction for connecting the frame construction to a scaffold component, in particular a vertical pole of a scaffold.

[0008] The proposed scaffold connection device allows an air-supported roof to be connected to scaffolding, enabling the air-supported roof to be used as a weather protection roof. A supporting structure, preferably made of aluminum or steel profiles, is not required in this case, thus minimizing the amount of material needed to construct the weather protection roof.

[0009] Another advantage of using an air-supported roof as weather protection is that, due to its dome shape, little to no snow accumulates. This eliminates the need for manual snow removal, thereby increasing safety. If the weather protection roof serves to protect a scaffolded construction site, it can be heated more easily in winter, as the membrane system of the air-supported roof, particularly the air and / or gas cushion formed between the membranes, minimizes heat loss. Similarly, the construction site can be cooled more easily in summer.

[0010] The proposed scaffold connection device comprises a frame structure and scaffold brackets connected to the frame structure. The air-supported roof is attached to the frame structure. The scaffold brackets, in turn, serve to attach the frame structure to the scaffold. The attachment is preferably achieved in such a way that the air-supported roof and the scaffold connection device can be disassembled without damage and, if necessary, re-erected at another location. An advantage of this design is that the frame structure is composed of several profiles, allowing the frame structure itself to be disassembled into several individual parts. Furthermore, the size of the frame structure can be varied by adjusting the number and / or length of the profiles.

[0011] In its final installed position, the frame structure preferably defines an area over which the air-supported roof can then be positioned. The air-supported roof then protects everything below and within this area from the elements. The external dimensions of the frame structure therefore essentially correspond to the external dimensions of the air-supported roof.

[0012] The frame structure serves to clamp and hold the at least one, preferably two, membranes of the air-supported roof, so that the connection between the air-supported roof and the scaffolding connection device is achieved via a clamping connection. Preferably, the at least one or the two membrane(s) are clamped around a perimeter, so that the clamping force can simultaneously be used as a sealing force, by means of which an air volume of the air-supported roof is sealed airtight to the outside. If two membranes are held, the air cushion for inflating the air-supported roof can be formed between these two membranes.

[0013] Preferably, the scaffold brackets of the proposed scaffold connection device have connecting elements at their ends facing away from the frame structure for connection to a scaffold component, in particular a vertical standard, of the scaffold. Typically, the vertical standards of a scaffold are arranged at standardized, regular intervals, so that the scaffold brackets can also be arranged at regular intervals. The regular connection of the frame structure to the scaffold ensures the necessary load-bearing capacity of the frame structure supporting the air-supported roof. The connecting elements arranged at the ends of the scaffold brackets are preferably designed to engage with a rosette-like connecting element of the scaffold component, in particular the vertical standard, and / or are designed as pipe couplings, for example, as round pipe couplings.In this case, the connection of the scaffold brackets can be achieved using standardized connectors, so that no special components are required.

[0014] Furthermore, the scaffold brackets preferably have connecting elements for attaching tensioning elements. This means that it is possible to attach tensioning elements, such as tension straps or cables. This is particularly advantageous when the air-supported roof has to bridge large spans, so that additional support for the roof can be provided by the tensioning elements. For this purpose, the tensioning elements are arranged below the air-supported roof. The connecting elements are preferably hook- and / or eyelet-type fasteners that, for example, allow a tensioning element end to be attached. Alternatively or additionally to the arrangement of connecting elements on the scaffold brackets, the frame structure can also have connecting elements for attaching tensioning elements. The loads are then transferred from the frame structure into the scaffold via the scaffold brackets.

[0015] The scaffold brackets preferably have connecting elements at their ends facing the frame structure for connection to the frame structure's profiles. These connecting elements are preferably designed to create a positive-locking connection, ensuring the frame structure is securely held on the scaffold brackets. To facilitate the assembly and disassembly of the scaffold connection device, it is further proposed that the connecting elements be designed to allow for a detachable plug-in, clamp, snap-in, and / or screw connection. For example, the connecting elements can comprise profiles extending transversely to the scaffold brackets, onto which the frame structure can simply be placed or plugged. Advantageously, the profiles project beyond the scaffold bracket on both sides, giving the scaffold bracket a T-shape when viewed from above.In this way, a support surface for the frame construction is created on both sides of the scaffold console.

[0016] The profiles of the frame structure preferably have a rectangular, and more preferably U- or C-shaped, cross-section. These cross-sections can also be present only partially within the profile. The rectangular shape creates at least one flat clamping surface for securely holding the at least one membrane of the air-supported roof. In the U- or C-profile configuration, the profile has a cavity open on one side, making it accessible. This cavity can be used, for example, to accommodate the connecting elements of the scaffold brackets. This is particularly relevant if the connecting elements are designed as profiles running transversely to the scaffold brackets. The opening of the U- or C-profile can then be oriented downwards, and the profile can simply be attached to a transverse profile of the scaffold bracket. The transverse profile of the scaffold bracket is then accommodated within the profile of the frame structure, thus achieving a positive-locking connection.Alternatively, the opening of the U- or C-profile can be oriented upwards, for example to accommodate an edge section of at least one membrane of the air-supported roof. Furthermore, the U- or C-profile design offers the advantage of material savings and a reduction in the weight of the frame structure, while maintaining high rigidity.

[0017] According to a preferred embodiment of the invention, the frame structure comprises a clamping strip that interacts with an outer clamping surface of the frame structure's profiles. During assembly of the air-supported roof, the at least one membrane can then be inserted between the profile's clamping surface and the clamping strip and clamped in place. The clamping strip is preferably screwable to the frame structure's profiles, so that the necessary clamping force can be applied via the screw connection. Instead of screws, other connection types or fasteners can be used. For example, rivets and / or wedges can also be used to create the connection, thereby applying the necessary clamping force.If more than one membrane, especially two membranes of the air-supported roof, are inserted between the clamping surface and the clamping strip, the clamping connection can simultaneously create a seal, allowing overpressure to be generated in the air space between the membranes. The clamping force then also serves as a sealing force. The clamping surface interacting with the clamping strip can be created, for example, by a U- or C-profile with its opening facing downwards. The top of the profile can then be used as the clamping surface.

[0018] According to a further preferred embodiment of the invention, the frame structure comprises an elastic, hollow and / or tubular and / or elastic tubular clamping element (hereinafter also referred to as an elastic, hollow and / or tubular and / or elastic tubular clamping element) which is inserted into the profiles of the frame structure and interacts with at least one inner clamping surface of the profiles. The clamping force can then be generated by inflating the tubular clamping element, whereby an edge section of the at least one membrane of the air-supported roof is first inserted between the profile of the frame structure and the clamping element. The profile, preferably a U- or C-profile, then accommodates not only the tubular clamping element but also the edge section of the at least one membrane. For ease of assembly and disassembly, the opening of the U- or C-profile is preferably oriented upwards.The clamping force exerted via the hose-like clamping element can also be used here as a sealing force, so that an air volume between two membranes of the air-supported roof is sealed airtight to the outside.

[0019] To solve the aforementioned problem, a scaffold with a scaffold connection device according to the invention is further proposed. The scaffold connection device enables the connection of an air-supported roof to a scaffold, thus creating a weather protection roof that increases occupational safety on the scaffold and / or the scaffolded construction site, depending on the area over which the air-supported roof is erected. Preferably, at least one scaffold bracket of the scaffold connection device is connected to a scaffold component, in particular a vertical standard, of the scaffold. The loads from the air-supported roof and the scaffold connection device are then transferred into the scaffold or scaffold component via the scaffold bracket(s), preferably scaffold bracket(s).

[0020] Furthermore, preferably at least one membrane of an air-supported roof is connected to the scaffolding via the scaffolding connection device. The connection of the air-supported roof to the scaffolding connection device is therefore made directly via the at least one membrane. Since an air-supported roof typically has at least two membranes or a double membrane, preferably at least two membranes of the air-supported roof are connected to the scaffolding connection device. The connection is also preferably detachable, so that the air-supported roof can be dismantled if necessary.

[0021] Preferably, the at least one membrane of the air-supported roof is clamped in an edge region between the profiles of the frame structure and a clamping strip. A clamping connection can be created using the clamping strip, which can be released again if necessary. Preferably, the at least one membrane is clamped in a circumferential edge region between the profiles of the frame structure and the clamping strip. In this case, the clamping connection can simultaneously create a seal between two membranes of the air-supported roof.

[0022] Alternatively, it is proposed that the at least one membrane of the air-supported roof be clamped at its edge between the profiles of the frame structure and an elastic, hollow and / or tubular clamping element. To create this clamping connection, preferably the edge of the at least one membrane is first inserted into the profiles of the frame structure, followed by the elastic, hollow and / or tubular clamping element. The necessary clamping force can then be achieved by inflating and / or filling the elastic, hollow and / or tubular clamping element, thereby pressing the at least one membrane against the inner walls of the frame structure profiles.Preferably, the at least one membrane is clamped in a circumferential edge area, so that the clamping force can also be used as a sealing force.

[0023] In a further development of the invention, it is proposed that at least one tensioning element, for example a tensioning strap and / or a tensioning cable, is arranged below the at least one membrane and attached to the scaffold connection device. The tensioning element can provide additional support for the air-supported roof. This enables very large spans for the air-supported roof. The at least one tensioning element can be attached using connecting elements, which are, for example, hook- and / or eyelet-like. The connecting elements can be arranged on the scaffold brackets and / or the frame structure of the scaffold connection device.

[0024] Advantageously, an intermediate layer, such as a mesh, is arranged between the at least one membrane of the air-supported roof and the at least one tensioning element. This intermediate layer prevents direct contact between the at least one tensioning element and the membrane, thus preventing mechanical damage to the membrane. The intermediate layer is particularly advantageous when the distance between the tensioning elements is very large. Otherwise, an intermediate layer can be omitted.

[0025] Preferably, the air-supported roof comprises at least two membranes enclosing an airtight volume, with the membranes clamped to the frame structure of the scaffolding connection device. Within the airtight volume, overpressure can then be generated, for example, using a blower or fan, causing the upper membrane to be lifted and tensioned. In its tensioned state, the upper membrane preferably forms a dome-like structure on whose surface neither rain nor snow can accumulate. Surface water flows off by gravity, and snow slides off by gravity. This means that no more snow needs to be removed manually.

[0026] Furthermore, the scaffold preferably comprises at least two scaffold sections arranged at angles to each other in the plan view. This angled arrangement of several scaffold sections allows for the definition of a construction area in the plan view, which is to be protected from the weather by the air-supported roof. The construction area can, for example, be rectangular or polygonal. In this way, even approximately circular construction areas can be scaffolded. A building or object to be protected can be located within the construction area. The object could, for example, be a monument or an archaeological site. The scaffold can be erected directly against the building or object, so that the external dimensions of the building or object determine the arrangement of the scaffold sections.If the air-supported roof is to be attached exclusively to the scaffolding, the scaffolding sections arranged at angles to each other preferably form a closed polygon, for example a rectangle.

[0027] Furthermore, it is proposed that the scaffolding include an opening assembly designed to provide an opening in an air-supported roof.

[0028] The opening assembly can comprise one or more, preferably two, support elements, wherein the one or more support elements are movable, in particular each, between a first and a second position, wherein preferably in the first position the air support roof substantially completely covers the area to be covered by the air support roof and in the second position, the air support roof does not cover the area to be covered by the air support roof in certain areas.

[0029] Alternatively or additionally, the opening assembly can comprise at least two support elements, wherein in the first position the support elements, preferably the two support elements, are in particular parallel to each other, preferably to form a particularly airtight and / or watertight seal and / or closure, and in the second position are spaced apart from each other.

[0030] Alternatively or additionally, the opening assembly can comprise one or more coupling elements, wherein preferably the one or more support elements are coupled to the frame by means of one or more coupling elements and / or are in operative connection and / or, preferably each, are movable between the first and the second position, wherein preferably the one or more coupling elements effect a translational and / or rotational movement between the first and the second position.

[0031] Furthermore, the opening assembly can comprise one or more actuating devices, preferably each for the one or more support elements, wherein the actuating devices are preferably each in operative connection with the one or more support elements and / or the frame and / or the one or more coupling elements in order to be able to move the one or more support elements between the first position and the second position.

[0032] It is also proposed that the one or more supporting elements comprise one or more frame structures composed of profiles for the preferably circumferential, clamping reception of at least one membrane, preferably two membranes of the air-supported roof, wherein optionally The profiles of the frame structure have a rectangular, preferably U- or C-shaped, cross-section; the frame structure comprises a clamping strip that interacts with an outer clamping surface of the profiles of the frame structure, the clamping strip preferably being screwable to the profiles of the frame structure; the frame structure comprises an elastic, hollow and / or tubular clamping element that is inserted into the profiles of the frame structure and interacts with at least one inner clamping surface of the profiles; and / or the frame structure has or has connecting elements for attaching clamping elements, the connecting elements preferably being hook- and / or eyelet-type connecting elements.

[0033] Alternatively or additionally, the one or more support elements, in particular each, can comprise one or more scaffold connection devices as described above, which are preferably connected to the respective one or more support elements.

[0034] Furthermore, a method for manufacturing a scaffold with an air-supported roof as weather protection is proposed. In this method, at least one membrane of the air-supported roof is connected to a scaffold component, preferably a vertical standard, of the scaffold using a scaffold connection device according to the invention. The method enables the simple connection of an air-supported roof to a scaffold. Effective weather protection can be achieved with minimal material usage using the air-supported roof.

[0035] Preferably, the at least one membrane of the air-supported roof, or more preferably an edge region of the at least one membrane, is inserted between a profile and a clamping strip of a frame structure of the scaffold connection device, and the clamping strip is connected to the profile, preferably screwed, to generate a clamping force. In this way, a clamping connection is created between the air-supported roof and the scaffold connection device, by which the air-supported roof is securely held. The clamping force can simultaneously be used as a sealing force, by means of which the volume between two membranes of the air-supported roof is hermetically sealed.

[0036] Alternatively, it is proposed that the at least one membrane, preferably an edge region of the at least one membrane, be arranged between a profile and an elastic, hollow and / or tubular and / or elastic, tubular clamping element of a frame structure of the scaffold connection device, and that the tubular clamping element be inflated and / or its volume increased or expanded and / or folded to generate a clamping force. In this case, the membrane or the edge region of the membrane and the elastic, hollow and / or tubular and / or elastic, tubular clamping element are received within the profile of the frame structure, so that the inner surfaces of the profile form clamping surfaces that interact with the clamping element. In this embodiment as well, a seal can be achieved via the clamping connection, so that the clamping force simultaneously serves as a sealing force.

[0037] Preferably, an overpressure is created in a volume that is airtightly enclosed by two membranes of the air-supported roof. This overpressure can be, for example, 25 to 40 mbar. Air is blown into the volume for this purpose, for example, using a blower or a fan. The overpressure ensures a dome-like shape for the air-supported roof, as it lifts and tensions the upper membrane. This dome shape ensures that the air-supported roof remains free of snow loads during its use.

[0038] Furthermore, the use of an air-supported roof as weather protection for scaffolding is proposed. In this proposed application, the air-supported roof replaces conventional weather protection roofs for scaffolding, which require more material and offer less protection compared to an air-supported roof. The air-supported roof in this proposed application thus helps to save costs and increase occupational safety on construction sites.

Detailed description of the drawings

[0040] Based on the Figures 1 to 4 A first preferred embodiment of a scaffold connection device 1 according to the invention is described, by means of which an air-supported roof 2 can be connected to a scaffold 10. The air-supported roof 2 can then serve as a weather protection roof.

[0041] The scaffold connection device 1 shown comprises a frame structure 4 composed of profiles 3, which enables the connection of the air-supported roof 2. The profiles 3 are U-shaped in cross-section and are attached with their openings facing downwards to profiles 13, which serve to connect the frame structure 4 to scaffold brackets 6. The profiles 13 thus form connecting elements 12. The profiles 13 are also U-shaped, with their openings also facing downwards. The outer dimensions of the profiles 13 are adapted to the inner dimensions of the profiles 3, so that a positive fit between the profiles 3 and 13 is achieved. The profiles 13 are welded firmly to the scaffold brackets 6.

[0042] The air-supported roof 2 has two membranes 5, the edge regions 18 of which rest on a clamping surface 15 of the U-shaped profiles 3 of the frame structure 4 and are held clamped by means of a clamping strip 14. The clamping force is generated by means of a screw connection (not shown) between the clamping strip 14 and the profiles 3. As in particular the Figure 2 As can be seen, the membranes 5 are held in place by a circumferential clamping force at their edge regions 18. In this case, the clamping force can simultaneously be used as a sealing force to tightly seal an air-filled volume 21 located between the two membranes 5. To increase the tightness, an intermediate layer 22 can be inserted between the profiles 3 and the lower membrane 5 in the clamping area. The intermediate layer 22 can, for example, be an elastomer strip (see Figure 4 ).

[0043] The scaffold brackets 6 of the illustrated scaffold connection device 1 serve to connect the frame structure 4 to a scaffold component of the scaffold 10, the scaffold component being a vertical upright 7. For this purpose, the scaffold brackets 6 have connecting elements 8 at their ends, which can be engaged with rosette-like connecting elements 9 of the vertical uprights 7. Similarly, in the illustrated scaffold 10, horizontal ledgers 23 are connected to the vertical upright 7 (see figure). Figure 1 and 2 ). Existing connecting elements 8 can therefore be used. In order to connect the scaffold connection device 1 to a vertical pole 7 at any height, the connecting elements 8 can also be designed as simple pipe couplings, in particular round pipe couplings, analogous to those in the Figures 5 to 9 (as illustrated embodiment).

[0044] To support the air-supported roof 2, one or more tensioning elements 19 can be arranged beneath it. For fastening the tensioning elements 19, the scaffold connection device 1 has connecting elements 11, which in this case are designed as hooks and / or eyelets and into which the tensioning elements 19 can be easily hooked (see Figure 1 and 3 To protect the lower membrane 5 from mechanical stress caused by a clamping element 19, an intermediate layer 20 can be arranged between the membrane 5 and the clamping element 19, for example in the form of a mesh (see Figure 4 ).

[0045] Another preferred embodiment of a scaffold connection device 1 according to the invention is described below with reference to the Figures 5 to 9The profiles 3, which form the frame structure 4, are in this case C-shaped in cross-section and oriented with the opening facing upwards. The edge regions 18 of the membranes 5 of the air-supported roof 2 are inserted into the profiles 3 and held in place by means of an elastic, hollow and / or tubular and / or elastic, tubular clamping element 16. The clamping force is achieved by inflating and / or filling the elastic, hollow and / or tubular and / or elastic tubular clamping element 16. The clamping element 16 then expands and presses the membranes 5 against internal clamping surfaces 17 of the profiles 3 (see figure). Figure 9 ). The clamping connection can also be used here to seal the air volume 21 between the membranes 5.

[0046] In the exemplary embodiment of the Figures 5 to 9The scaffold brackets 6 of the scaffold connection device 1 have connecting elements 8 in the form of simple round tube couplings at their ends facing away from the frame structure 4. As exemplified in the Figures 10 and 11 As shown, connecting elements 8 can also be used which can be brought into engagement with a rosette-like connecting element 9 of a vertical post 7. The round tube coupling has the advantage that the height of the scaffold connection device 1 can be chosen arbitrarily, in particular independently of the height of a rosette-like connecting element 9 (see Figures 6 to 8 ).

[0047] In the embodiment of the Figures 5 to 9 as well as in the embodiment of the Figures 10 and 11At least one tensioning element 19 can be arranged under the air-supported roof 2 to provide additional support for the air-supported roof 2 (not shown). In this case, an intermediate layer 20, for example in the form of a mesh, is preferably inserted between the lower membrane 5 and the tensioning element 19 to protect the membrane 5 from mechanical damage.

[0048] In Figure 12Figure 1 is a perspective view of an opening assembly 100. The opening assembly 100 has at least one support element 101, which can be configured to move between a first position and a second position. The first position can, in particular, be a closed position. This can mean, among other things, that in this position a weather protection roof, especially in the form of an air-supported roof 2, is closed, i.e., completely covers the area of ​​the construction site, building, and / or object to be covered by the weather protection roof.

[0049] In the second position, which specifically represents an open position, a section of the weather protection roof, in particular the air-supported roof 2, is opened. This can mean, in particular, that at least part of the area to be covered by the weather protection roof is exposed. For example, the opening assembly 100 can provide an opening 107 in the air-supported roof 2, which allows, for instance, the entry of building materials and / or equipment and / or other elements that can / must be lifted into place by crane.

[0050] In the present case in Figure 12 In the embodiment shown, the opening assembly 100 for the weather protection roof comprises, in addition to the first support element 101, a second support element 102. The first and second support elements can be arranged parallel to each other and / or extend over the entire span of the roof 2.

[0051] In the first, closed position, the first and second support elements 101, 102 can be arranged adjacent to each other. On the side facing away from the other support element 101, 102, as shown in Figure 12 not explicitly shown but in the Figures 15 to 18 schematically demonstrated, a corresponding air-supported roof 2 or a part of a multi-part air-supported roof 2 is arranged.

[0052] A support element 101, 102 of the opening assembly 100 can comprise a corresponding frame structure 4, which provides a connection, in particular an airtight connection, to the at least one membrane 5, preferably two membranes, of the air-supported roof 2. Alternatively or additionally, an embodiment of the scaffold connection device 1 described above can be connected to the, for example, grid-shaped support element 101, 102.

[0053] Alternatively or additionally, the support element 101, 102 can comprise another connecting device, such as ropes and / or hooks, which can connect the membrane(s), in particular detachably, to the support element.

[0054] The air-supported roof 2, or a part thereof, can accordingly provide a connection between the first and second membranes 5, which, together with the preferably surrounding frame structure 4, provide a sealed volume 21 for the introduction of a gas or overpressure to inflate the air-supported roof 2. The first and second membranes 5 can, in particular, be made in one piece. The first and second membranes 5 can be formed by corresponding areas of a membrane material, for example, by overlapping areas which, by connection to the profiles of the frame connection device 1, form a corresponding, in particular sealed, volume 21, which can be filled with air and / or another gas and / or gas mixture and / or pressurized to inflate the air-supported roof.

[0055] As in Figure 11The first and / or second support element 101, 102 can be rotatably mounted. Such a rotation bearing 105, 106 can be attached to the framework supporting the air-supported roof. In the present embodiment, each support element 101, 102 can be moved from the first, closed position to the second, open position and back again via a corresponding coupling element 105, 106 by means of one or more actuating devices. A corresponding actuating device 103, 104 can be provided for the support element(s), in particular for each support element 101, 102. The actuating device 103, 104 can be operated hydraulically, pneumatically, and / or mechanically. In the present embodiment, corresponding telescopic rods transmit the rotation. The actuating device(s) 103, 104 can be controlled by a control unit, which, for example,a remote control and / or coupling with an overpressure system for erecting or unfolding the air-supported roof 2 is enabled.

[0056] Alternatively or additionally, it can also be provided that the actuating device 103, 104 accomplishes a translational movement, in particular instead of or in addition to a rotational movement. In addition to the actuating device 103, 104, the coupling element(s) 105, 106 can then also be configured accordingly.

[0057] In Figure 13The open position is shown. The first and second support elements 101, 102 are separated from each other, for example, by a rotational movement. Accordingly, the coupling element(s) 105, 106 can be configured to effect a rotational movement of the support element(s) 101, 102 about an axis. In addition to rotation, a translateral movement, in particular a displacement, can also be achieved (not shown).

[0058] By moving to the second position, the corresponding air-supported roof 2 can be displaced or shifted. If the air-supported roof 2 is formed, for example, by two membranes 5, the volume 21 formed by the membranes 5 can be reduced or displaced accordingly. An opening 107 is formed between the support elements, through which material and / or objects can be inserted, for example, by a crane.

[0059] In one embodiment, the first and second support elements 101, 102 can abut each other in such a way that an airtight seal is enabled.

[0060] In Figure 14 and Figure 15 The corresponding side views of the opening assembly 100 are shown, wherein in Figure 13 the first closed position is shown and in Figure 14 the second, open position is shown. Figure 15 A correspondingly formed opening 107 can be identified. It can also be seen how the actuating devices 103, 104 for the respective support element 101, 102 are extended (first position) or retracted (second position).

[0061] In Figure 16Figure 1 shows a schematic representation of the opening assembly 100. In the present embodiment, the air-supported roof 2 comprises two parts. However, more than one part can also be provided. Each of these parts can comprise two membranes 5, each of which in turn forms a volume 21. The parts are separated by the opening assembly 100, to which each part of the air-supported roof 2 is suspended on one side by a respective support element 101, 102. As can be seen in the schematic representation, the two membranes can be designed such that a volume 21 to be filled is formed between the membranes 5.

[0062] As schematically indicated here, the two membranes can be provided as a single piece or connected to each other on the side of the support element 101, 102. This can be achieved, for example, by additional clamping profiles or frame connection devices, which can be attached to or encompassed by the respective support element, for instance by a permanent connection of the membranes 5 such as a seam or a weld. In any case, the connection on the support element can be airtight, so that an airtight volume is formed which can be pressurized to unfold the air-supported frame.

[0063] In Figures 16 and 17 It is also shown that the membrane can be suspended from the supporting element by ropes or hooks.

[0064] The opening assembly 100 is used in Fig. 17The structure is shown in an open position. The first and second support elements 101 and 102 are rotatably coupled to a framework (not shown) via respective coupling elements 105 and 106, so that a rotational movement allows the support elements 101 and 102 to unfold, creating an opening 107. Through this opening 107, building materials or other materials or objects can then be introduced, for example, by crane, into the area covered by the air-supported roof of a construction site or other location.

[0065] In the Figures 18 and 19Another embodiment of the opening assembly 100 is shown. This assembly comprises, as a coupling element 105, for example a rail device, which can be arranged on the supporting frame (not shown). Attached to and / or operatively connected to it is the support element 101, to which an air-supported roof 2 is attached, for example by clamps, via profiles and / or a corresponding frame connection device 1. The air-supported roof 2 can again comprise two membranes 5, which can enclose a volume 21, which can then be pressurized to inflate the air-supported roof 2.

[0066] The supporting element 101 can be used as in Figure 18 shown in a first position in which the air-supported roof 2 is completely closed.

[0067] In Figure 19However, a second position is shown in which the air-supported roof is open. The supporting element can then be moved accordingly by a translational movement, in this example by a linear movement from the first position ( Fig. 18 ) into a second position ( Fig 19 ) transferred and thus pushed back as shown in this example to provide an opening 107 for the entry of material, similar to a sunroof.

[0068] Alternatively or additionally, besides the translational movement, a further additional rotational movement can also be provided. In the exemplary embodiment of the Figure 18 and the Figure 19The coupling element 105 comprises a first end and a second end, wherein the support element 101 moves from the first end to the second end when moving from the first to the second position. For this purpose, the coupling element 105 can be operatively connected and / or linked by means of a suitable actuating device, for example, a linear actuator.

[0069] The coupling element 105 can also have a corresponding guide track or other guide means with which the support element 101 can be moved from the first to the second position and back again. Reference symbol list
