Description

[0001] The disclosure relates to a mobile structure, preferably a tent, with a supporting structure consisting of a plurality of structural elements connected along circumferential sections to adjacent structural elements, and which are designed in the manner of a polygon, wherein at least some of the circumferential sections are formed by inflatable edge tubes. State of the art

[0002] The applicant sells tents under the brand name "X GLOO" ®, such as catering tents, first aid / medical tents, trade fair tents, or other event tents, in which the outer shell is stretched and stabilized by inflatable columns. These columns are equipped, for example, with a one-pump system, so that inflating / filling the column with air can be done very easily with one or very few valves. The outer shell – also called the roof – is made of a wear-resistant, preferably waterproof and weather-resistant material that can withstand intensive stress.

[0003] A disadvantage of these well-known mobile structures is that, due to their construction with arched, inflatable support columns, the size of the structure is limited to a comparatively small area.

[0004] A pop-up roof for a camping vehicle is known from the prior art, in which the side walls are formed by inflatable hollow chamber wall sections. In one specific embodiment, these wall sections are formed from a plurality of adjacent column structures, which are covered on the inside and outside with a cover, so that the column structure is not visible.

[0005] The columns of the solutions described above are designed in the style of a kite tube and have an airtight inner shell (bladder) covered by a wear-resistant outer shell.

[0006] The columns of the column structure, as well as the inner and outer coverings, are sewn together, making the manufacturing process complex. Another disadvantage is that the columns limit the degrees of freedom in designing the spatial structure. In principle, this type of concept is only suitable for covering relatively small floor areas.

[0007] In contrast, the patent application DE 10 2021 109 798 A1, which originates from the applicant, shows a tent with a multitude of polygonal structural elements, the circumferential sections of which are bounded by textile, inflatable edge tubes. It is proposed that both the hollow chambers of the edge tubes and the corner areas, which combine to form the respective structural element, be made from a single woven web, for example, as a one-piece woven structure. In this way, the structural element is, in the broadest sense, a single piece and, with simple manufacturing and handling, can cover a comparatively large area. Brief description of the revelation

[0008] In contrast, the revelation is based on the task of creating a mobile structure that, while being easy to handle and lightweight, has greater stiffness, so that the structure can span a larger area.

[0009] This problem is solved by a mobile structure with the features of claim 1.

[0010] Advantageous further developments of the disclosure are the subject of the subclaims and / or are explained below.

[0011] In the following discussion, the term "mobile structure" refers to a mobile, movable architectural structure that can be assembled and / or disassembled with relatively little effort, making these concepts suitable for short-term use. Such structures may also be eligible for approval as "temporary structures," such as a beer tent.

[0012] The mobile structure according to the disclosure is preferably designed as a tent and has a supporting structure with a plurality of structural elements that are connected to adjacent structural elements along circumferential sections and are configured in a polygonal shape, wherein at least some, preferably all, of the circumferential sections are formed by inflatable perimeter tubes. The mobile structure is accordingly brought into its operating position by inflating the perimeter tubes and, if necessary, adding additional bracing. For dismantling, the air is then released accordingly, so that the supporting structure can be easily folded and stored in a small space. According to the disclosure, the perimeter tubes have an inflatable support element to which end pieces or end caps are attached at their axial ends. The support element preferably extends centrally between the end caps and can extend straight or curved, depending on the desired shape of the structure.According to the disclosure, the end pieces are each connected to a connecting component.

[0013] By connecting the end pieces to the connecting component, the force transmission between the pneumatic edge tubes is direct and its direction of action is clearly defined, or at least almost clearly defined. The corner areas of the respective structural element are therefore stiff or particularly stiff, which, combined with easy handling through inflation and deflation, results in a structure with higher stiffness due to the high volume fraction of inflatable support elements in the supporting structure, especially its empty weight, and thus allows it to span a larger area.

[0014] According to a further development, at least one of the connecting components or end pieces is elastically designed, or at least one of the end pieces is connected to the connecting component via an elastic coupling element. The coupling element is preferably designed as a damping element or rubber buffer element with a preferably progressive spring characteristic.

[0015] Additionally or alternatively, at least one of the connecting components or end pieces is rigidly designed and / or at least one of the end pieces is rigidly connected to the connecting component.

[0016] In this way, the following combination possibilities arise for each connection in terms of design: The connection of the end piece to the connecting component with an elastic coupling element, in other words the elastic connection, or the connection of the end piece to the connecting component with a rigid coupling element or without a coupling element, in other words the rigid connection; furthermore, the rigid design of the connected end piece and the connecting component; the elastic design of the connected end piece and the connecting component; the rigid design of the connected end piece and the elastic design of the connecting component, and vice versa, the elastic design of the connected end piece and the rigid design of the connecting component.

[0017] Due to the aforementioned variety of possible combinations, which can be individually selected for each connection, the stiffness of the respective connection can be specifically and locally influenced, allowing the properties of the structure, in particular the stiffness, load-bearing capacity, resistance to wind load and superimposed load, as well as vibration behavior, to be optimally adjusted.

[0018] According to a preferred further development, the respective end piece or connecting component exhibits a progressive spring characteristic in the case of its elastic design.

[0019] If all end pieces are rigidly connected and the end pieces and connecting components are rigidly designed, the structure will have a correspondingly maximum stiffness. By selectively designing the connection(s), end piece(s), and / or connecting component(s) with elasticity, a specific characteristic of the structure can be tailored.

[0020] In principle, this results in a small pack size for the dismantled structure, even with high or very high rigidity. The individual edge tubes with their end pieces and the connecting components enable flexible and therefore faster assembly and disassembly. Furthermore, the inflatable edge tubes and the connecting components represent basic elements for the flexible modularization of the structure.

[0021] The edge tubes can be pre-assembled as structural elements, either unpressurized or with a suitable transport pressure, or they can be supplied individually as modular basic elements. Due to the high stiffness in the corner areas of the structural elements of the supporting structure, compliance with the standards and static requirements for temporary structures (construction log) is readily achievable, and a covered area of ​​up to approximately 100 m² is feasible.

[0022] Depending on the design of the polygonal structural elements, very stable structures with almost any floor area can be created, so that this concept is also applicable to large tents, such as exhibition tents, event tents or the like.

[0023] Parameters for the design of the structural elements can be, alternatively or additionally to the above-mentioned rigidity or elasticity and spring characteristics, a length and diameter of the edge tubes, their filling pressure, a size of the structural elements, a symmetry or asymmetry of the structural elements, a number of vertices of the respective polygon, a tensioning of the edge tubes by means of at least one tensioning or pulling device, or an arrangement of the respective structural element with regard to its neighboring structural elements.

[0024] According to a further training, the structural elements are preferably designed such that at least one of the edge tubes is assigned to two adjacent structural elements and thus forms a circumferential section of both structural elements.

[0025] In a preferred embodiment of the disclosure, the structural elements are designed as quadrilaterals, pentagons, or hexagons. Of course, other geometries and hybrid forms are also possible.

[0026] Preferably, a corner angle of the associated polygonal structural element is predetermined or set via the connecting component and the end pieces connected to it adjacent to one another. It should be noted that, in the case of a rigid connection and design of the end piece and the connecting component, the corner angle is predetermined or set with the highest angular fidelity, and that, with an elastic connection or elastic design of the end piece or connecting component, or both, the angular fidelity decreases accordingly, and the corner angle increasingly adjusts itself depending on the stress conditions on the structural element.

[0027] Alternatively or additionally, end pieces are attached diametrically to the connecting component, so that the edge tubes radiate diametrically from the connecting component and together form one of the circumferential sections of the associated structural element. In this case, the angle spanned by the edge tubes attached in this way is, for example, 180°. Thus, the connecting component can join several edge tubes to form one, preferably straight, circumferential section.

[0028] Alternatively, the circumferential section can of course be formed by two connecting components and three edge tubes, or more generally, by a multitude of alternately arranged connecting components and edge tubes, whereby, for a given length of the circumferential section, the proportion of non-pneumatic components (end piece, possibly coupling element, connecting component) increases and the proportion of pneumatic components decreases.

[0029] The connecting component can be located in a central area of ​​the supporting structure of the building, so that edge tubes are fully connected to the respective connecting component, in particular with predetermined corner angles, or it can be located in an edge area of ​​the supporting structure of the building, so that the edge tubes are partially connected to it, and in particular with predetermined corner angles.

[0030] Preferably, all circumferential sections of the supporting structure are formed by the inflatable edge tubes and all edge tubes are connected to the polygonal structural elements via the aforementioned rigid or elastic connecting components as disclosed.

[0031] Alternatively, at least one of the circumferential sections is formed by a rigid strut.

[0032] Preferably, a circumferential section of the rigid strut is formed on an edge side of the structure, particularly in an area of ​​a foundation or support of the structure, which can, for example, facilitate a first construction step when erecting the structure, in particular a connection of the supporting structure to the foundation or support.

[0033] The rigid connecting components as disclosed can of course have the same or different designs, which depend in particular on the number and intended corner angle of the respective connected end pieces / edge tubes.

[0034] The structure, or more precisely its supporting structure, preferably consists of structural elements designed as a square, pentagon or hexagon or as another polygon, whereby the supporting structure can also be formed from mixed forms of these geometries.

[0035] Each structural element, more precisely the connecting components and the edge tubes attached to them via the end pieces and optional coupling elements, can span a plane or a curved surface. The structure can be composed solely of planar structural elements, solely of curved structural elements, or of both.

[0036] At points on the supporting structure where the structural elements meet at their corners, the edge tubes of these structural elements are preferably connected to a common connecting component located there. This component accordingly has a sufficient number of connection sections for the end pieces and a sufficiently narrow angular distribution of the connection sections.

[0037] According to further training, a large number of the connecting components, preferably all connecting components, are identical - and thus designed as a single, identical part.

[0038] If the supporting structure consists of dissimilar structural elements that differ, for example, in the number of their corners, then the common parts / connecting components are so over-dimensioned with regard to the number of their connection sections and angle distribution that not every connection section has an end piece attached, and some end pieces are attached at a greater angular distance than would theoretically be possible. In other words, some connection sections remain free or unused. This allows the use of identical connecting components as common parts, largely independent of the shape of the structural elements.

[0039] The structural elements are preferably arranged such that at least one of the edge tubes is assigned to two structural elements, so that the structural elements extend on both sides of this edge tube.

[0040] Preferably, the set of structural elements, in particular a roof or dome formed by them, is connected to a foundation or support of the structure via several of the connecting components.

[0041] Preferably, the structure has several foundations or supports arranged at widely distributed intervals.

[0042] According to further training, such a foundation or support is preferably designed as a container or bag that can be filled with weight, for example with water.

[0043] Preferably, the container or bag, when empty, especially when the structure is not yet erected, is intended as a transport volume in which the components of the structure, for example the edge tubes, the connecting components, the support elements, the end pieces, the coupling elements, the cover layers, fasteners, tensioning devices and the like, can be stored.

[0044] To increase the stiffness of the respective structural element, according to a further development, at least one, preferably flexible, tensioning device is provided on the structural element. Preferably, the tensioning device has several tensioning elements, preferably tensioning straps, radiating from the connecting component.

[0045] In a preferred embodiment, a connecting component of the structural element is connected via the clamping device to at least one other connecting component of the structural element, which is arranged, for example, opposite the structural element, by a tensile force. Preferably, the connecting component is connected via the radiating clamping elements or straps to all connecting components arranged opposite the structural element.

[0046] In the case of a planar structural element, the clamping device extends in a plane spanned by the edge tubes, stabilizes the force triangles formed by the edge tubes and thus increases the static resistance of the structural element to twisting and deflection.

[0047] Apart from external forces, such as gravity or wind forces, the clamping effect of the clamping device means that the edge tubes preferably exert compressive forces and the attached clamping device exerts a tensile force on the connecting component.

[0048] Preferably, the clamping device is adjustable in length and / or verifiable, so that the preload of the structural element can be adjusted and / or verifiable. The preload is preferably set high enough to ensure that, under expected / specified external forces, the structural element remains as stiff and free of torsion as possible, and / or that bearing forces at the connection points of the edge tubes and the clamping device on the connecting component remain within their specified limits.

[0049] The tensioning device can be adjusted by making the length of the tensioning strap(s) adjustable, and / or by attaching the tensioning device to the connecting component via a tensioning device that can be tightened. Such a tensioning device can, for example, be designed as a tie rod that passes through a through-hole in the connecting component, such as a threaded bolt with a lockable clamping nut.

[0050] To minimize the adjustment or movement required for setting or adjusting the clamping device, it preferably has a high modulus of elasticity. For example, straps or ropes made of polyethylene fibers with preferably (ultra)high molecular weight are suitable as flexible materials with high strength and a high modulus of elasticity.

[0051] Preferably, the connection sections of the end pieces to the connecting component are formed by, preferably planar, end faces that are angled relative to each other according to a corner angle of the structural element. An end piece of a side tube is then connected to each of the end faces. In this way, the corner angle of the connecting component is predetermined.

[0052] As already explained above, the actual corner angle depends on the corner angle predetermined on the connecting component, the rigid or elastic design of the end pieces and the connecting component, and the stress conditions on the structural element, in particular due to the at least one clamping device or tensioning device.

[0053] It should be noted that the actual corner angle will have the highest angular fidelity – i.e., the smallest angular deviation – to the corner angle predetermined by the connection sections of the connecting component if the connections, the end pieces and the connecting component are each rigidly designed.

[0054] As soon as one of the end pieces, its connection or the connecting component is not rigid but elastically designed, the angular accuracy decreases accordingly and the actual corner angle increasingly depends on the stress conditions on the structural element.

[0055] Preferably, the clamping device is attached between the end faces, preferably in a region of an angle bisector of the corner angle.

[0056] According to a preferred embodiment, the end faces have a respective receptacle, preferably a through-recess, into which a bearing section, preferably a centering section, of the end piece is inserted or which is penetrated by a bearing section, preferably a centering section, of the end piece.

[0057] According to one possible variant, the elastic or rigid coupling element is arranged in an area of ​​the receiving device, into which a bearing section, preferably a centering section, of the end piece is inserted, or which is penetrated by a bearing section, preferably a centering section, of the end piece.

[0058] Preferably, the end piece is fixed to the end face by means of fasteners, for example, by forming at least three through holes evenly distributed around the circumference of the receptacle, through which screws are inserted into threaded holes formed on the end face of the end piece. Of course, alternative fasteners are possible.

[0059] The supporting structure preferably has a single-segment or multi-segment deck layer that is tensioned, thus protecting the interior of the structure from weather influences. Due to the disclosed connection of the edge tubes via the connecting components, the structure proves to be wind-stable even with this deck layer.

[0060] The cover layer can span several, for example all, structural elements, or it can be composed of several cover layer segments, each with a geometry corresponding to that of the polygon of the respective structural element. In this case, the set of cover layer segments forms the cover layer. Preferably, the structural elements are fully and tightly connected to one another.

[0061] In the case of the design of the deck layer by deck layer segments, the aforementioned tensioning device supports the resistance of the respective deck layer segment to deflection, which may result, for example, from a wind load.

[0062] The cover layer segments can be designed, for example, as a cover sheet, cover layer, or cover membrane.

[0063] According to a further development, at least one of the structural elements is provided with a cover layer segment. The cover layer segment has a number of corner sections corresponding to the polygon of the structural element. At least two corner sections are provided in the area of ​​the connecting components of one of the edge tubes. The corner sections of the cover layer segment are connected to the connecting components of the structural element in a tensile-resistant manner, preferably under prestress.

[0064] Preferably, a tab or eyelet, for example a shackle, is provided at each corner section.

[0065] A pulling element preferably attaches to the connecting component on one side and the tab / eyelet on the other, so that a pulling force can be applied and adjusted.

[0066] Unlike the clamping device mentioned above, which connects opposing connecting components and applies tension, the tensioning device described here clamps or tightens the corner section of the cover layer segment on the respective connecting component. This allows the cover layer segment to be tensioned across its surface on the connecting component(s), particularly to ensure it is wrinkle-free and / or to increase the stiffness of the structural element.

[0067] According to a further development, the cover layer segment has a force transmission element that extends concavely between two adjacent corner sections. Concave here means, in particular, that it is curved towards the center of the cover layer segment. The force transmission element is designed and configured to absorb a load acting on the cover layer segment at a point or over a surface and to transfer or dissipate at least a portion of it to the corner sections.

[0068] Preferably, the cover layer segment is designed with the force transmission element such that the load acting on the cover layer segment results in a tensile force acting on the force transmission element, the force transmission element transmits the tensile force to the two corner sections, and the two corner sections transmit the tensile force proportionally to the respective connecting component to which they are tensilely connected. Subsequently, the connecting components absorb this force and transmit it to the end pieces of the inflatable / inflated rim tube.

[0069] In this way, the respective rim tube is predominantly subjected to axial loads, or the particularly critical transverse load or bending load of the rim tube is at least reduced, so that the risk of breakage of the rim tube is reduced.

[0070] Preferably, the force transmission element extends across or along the surface of the cover layer segment. In particular, it is integrated or embedded in the cover sheet, cover layer, or cover membrane of the cover layer segment, especially by sewing, welding, or bonding. The force transmission element preferably extends linearly. It is preferably flat, particularly as a strip or belt. In particular, it can be made of high-strength textile, for example, Kevlar, or alternatively as a steel cable to enable high force transmission with a small cross-section.

[0071] According to further training, the cover layer segment has a surface section extending from the force transmission element to the edge tube, which is connected to the edge tube in a virtually stress-free or at least stress-reduced manner. In this way, the cover layer segment provides a weatherproof seal at the respective edge tube, and at the same time, due to the virtually stress-free or at least stress-reduced connection, the critical transverse force or bending load described above is almost eliminated or at least reduced.

[0072] The connection of the cover layer segment(s) to the edge tubes can be achieved by means of essentially cylindrical sleeves or sockets extending along the edge of the cover layer segment, each containing one of the edge tubes. This provides a simple and compact connection of the cover layer segments to the supporting structure, including any walls and tunnels. A particular advantage is that the cover layer segment is connected to the respective edge tube along a linear path rather than at a single point, thus effectively preventing point-like transverse loading of the edge tube.

[0073] According to further training, the aforementioned surface section of the cover layer segment, which extends from the force transmission element towards the edge tube, is attached to the cover or quiver by means of a zipper in a virtually tension-free or at least tension-reduced manner.

[0074] The cases or quivers are preferably designed so that the rim tubes are easy to insert and easy to remove.

[0075] To enable the replacement or exchange of the cover layer segment while the supporting structure is erected, particularly with inflated edge tubes, and without having to dismantle the supporting structure, a further development proves advantageous in which the sleeves or quivers have a closable access point along their axial extension, through which the respective edge tube can be inserted laterally. The access point is preferably designed as a zipper. In this way, the erected structure can be quickly reconfigured with a different design, logo, or advertising message without having to dismantle the underlying supporting structure.

[0076] In order to enable axial insertion and removal of the rim tube, the casing or quiver, according to a further development, has an opening at at least one of its axial end sections pointing towards the connecting component there, with at least the diameter or cross-section of the respective support element or rim tube being received.

[0077] To form an axial stop in the sleeve or quiver, against which the rim tube is axially fixed, the sleeve or quiver, according to a further embodiment, has an opening at at least one of its axial end sections facing the connecting component there, which is narrowed relative to the diameter or cross-section of the respective support element received. The shape of the narrowed opening is preferably adapted to the shape of an outer surface of the end piece. In particular, it is formed by a conical taper of the sleeve or quiver, for example as a collar.

[0078] Preferably, at least one of the end pieces of each rim tube has a compressed air connection that is in compressed air contact with the support element of the rim tube.

[0079] According to a further training, at least one of the connecting components is designed and constructed to be non-fluid-tight, non-fluid-carrying, and / or non-fluid-connecting. Therefore, its topology can be optimized for the mechanical function of force absorption and transmission; a fluidic function need not be considered. This allows for a high load-bearing capacity and stiffness to be achieved with a low-weight connecting component, resulting in advantages for the overall weight as well as for the achievable load-bearing capacity and stiffness of the entire mobile structure.

[0080] According to further training, the connecting component is formed as a hollow body that is designed and constructed to be open on one or more sides.

[0081] The hollow body preferably has openings and / or recesses. These allow for a high load-bearing capacity despite the low weight.

[0082] According to a further development, the compressed air connections of the end pieces attached to at least one of the connecting components are connected to a permanently open compressed air hose – open in the sense of a permanent compressed air connection – or a shut-off compressed air hose, so that they are either in a permanent compressed air connection, or can be connected to compressed air as needed, or their compressed air connection can be interrupted. In this way, the compressed air-connected edge tubes, preferably all edge tubes of a structural element or several structural elements, can be filled with compressed air via a common connection, and the compressed air can be released accordingly.

[0083] Even in this further development, the connecting component in question is not designed to be fluid-tight, fluid-carrying, or fluid-connecting, as described in the disclosure. The fluid-tight, fluid-carrying, and fluid-connecting functions are instead fulfilled solely by the compressed air hose. The connecting component may be touched, crossed, or penetrated by the compressed air hose.

[0084] According to the disclosure, the compressed air hose is therefore a separate component from the connecting part. In other words, according to the disclosure, the compressed air hose is not part of the connecting part.

[0085] Preferably, the compressed air connection at the end piece is coaxial with the support element. Alternatively, it can be arranged with a radial component protruding from the end piece to improve its accessibility.

[0086] Preferably, the compressed air connections are arranged within a space occupied by the connecting component. In this way, the compressed air connections, and preferably also the compressed air hose, are protected against external damage, especially damage from impact.

[0087] The connecting component is particularly cost-effective and simple to construct, made from sections, preferably sheet metal sections. These sheet metal sections can be punched or cut, for example, laser-cut. Preferably, the sheet metal sections are bent. Alternatively, the connecting component can, of course, be a casting, a milled part, or an additively manufactured component. The end faces mentioned above are formed from one of the sheet metal sections, and a stiffening section is formed from at least one other sheet metal section.

[0088] The connecting component can be pot-shaped with a pot base and a surrounding pot wall. The pot base then preferably forms the stiffening section and the pot wall the end faces. Such a design is preferred for those connecting components that are located in the central area of ​​the supporting structure of the building and / or to which the end pieces are fully connected.

[0089] The connecting components arranged in the edge region of the supporting structure and / or the connecting components to which the end pieces are partially attached are preferably designed in the form of a U-profile. The end faces to which the end pieces are attached are then preferably formed by legs or leg sections of the U-profile, whereas the stiffening sections are preferably formed by struts or cover plates via which the legs are connected.

[0090] The support elements are preferably two-layered, with a radially outer layer and a radially inner layer. This two-layered structure allows for optimal adjustment of the respective functions of the support elements, such as abrasion resistance, dimensional stability, and airtightness, and thus the load-bearing capacity of the edge tubes, structural elements, supporting structure, and ultimately the building as a whole.

[0091] The outer layer preferably fulfills the function of a shape-retaining shell.

[0092] Preferably, the radially outer layer is formed of a material, particularly a textile, whose primary property is high dimensional stability of the support element, especially against internal pneumatic pressure. An alternative or supplementary property of the outer layer is high abrasion resistance, so that the support elements are protected against abrasion and damage, particularly during the assembly process of the supporting structure, in which the support elements must be handled close to the ground.

[0093] The inner layer preferably fulfills the function of an airtight, elastic hose or hose element.

[0094] Preferably, the end pieces are attached to the support element by independently fixing or attaching the radially outer and the radially inner layers of the two layers to the end pieces.

[0095] To fasten the end pieces to the support element, the end pieces preferably each have at least two axially spaced circumferential grooves. The radially inner, particularly airtight, layer (hose element) is fixed to the axially inner of the two circumferential grooves, and the radially outer, particularly dimensionally stable and abrasion-resistant, layer is fixed to the axially outer of the two circumferential grooves. In this way, the radially outer layer, which is particularly dimensionally stable and abrasion-resistant, completely covers the radially inner layer, which is particularly more sensitive and airtight, in both the axial and circumferential directions, protecting it from damage and defining its shape.

[0096] The two layers are preferably secured in their respective circumferential grooves by a winding of rope or wire. This winding technique provides a simple and secure way to attach the end pieces to the support element, and the strength of the connection can be influenced by the wrapping angle and pretension of the rope or wire. A sealant between the axially inner circumferential groove and the radially inner groove of the layers secured to it preferably increases the airtightness.

[0097] The structure as described preferably has a large number of identical edge tubes. In this way, the edge tubes can be standardized as identical parts and therefore manufactured and maintained cost-effectively.

[0098] As an alternative to the two-layer construction of the support element described above, it can of course be made from a coated, one-piece woven textile structure. In that case, only one of the circumferential grooves described above is necessary for fastening at the respective end piece.

[0099] In a preferred embodiment, which is based on the embodiment with edge-side sleeves or quivers of the cover layer segments, at least one of the end pieces of the respective edge tube has a, in particular a third, outermost circumferential groove in the axial direction, on which the sleeve or quiver, preferably a tensioned edge of the sleeve or quiver, is fixed.

[0100] The appearance of the connecting component is preferably of high quality, so that it can serve as a design element of the building. Short description of the characters

Detailed description of the characters

[0102] Figure 1 Figure 1 shows an embodiment of a mobile structure 1, designed as a trade fair or event tent. It has a basic cross-section in the form of a heptagon, around which ballastable, mobile supports 2 are arranged at uniform intervals. In the illustrated embodiment, the box-shaped supports 2, when the structure 1 is disassembled, provide space for storing and transporting components of the structure, thus fulfilling an efficient dual function.

[0103] A dome-shaped, partially pneumatically operated support structure 4 of the structure 1 is connected to the box-shaped supports 2. In the illustrated embodiment, the support structure 4 has three identical, frame-shaped structural elements 6a, 6b, 6c, each in the form of a planar pentagon. Each pentagon has circumferential sections, each formed by an inflatable edge tube 8. Edge tubes 8a at the periphery are assigned to only one of the structural elements 6a, 6b, 6c, whereas edge tubes 8b arranged in a central area of ​​the structure 1 are each assigned to two adjacent structural elements 6a, 6b, 6c.

[0104] The edge tubes 8 are according to Figure 2 According to the disclosure, the structure is formed from an inflatable, cylindrical support element 12, to each of whose two end sections a rigid end piece 18 is sealed. According to the disclosure, the end pieces 18 are rigidly connected to the rigid connecting components 10, which will be explained in more detail later.

[0105] It should be emphasized that, as an alternative to the rigid design of the connections, end pieces 18, and connecting components 10 shown in the exemplary embodiments, elastic designs are also possible. Naturally, all combinations of rigid / elastic end piece / connecting component are possible in order to, for example, adjust a characteristic of the structure: rigid end piece, rigid connecting component; elastic end piece, rigid connecting component; elastic end piece, elastic connecting component; rigid end piece, elastic connecting component.

[0106] Furthermore, the connection of the respective end piece to the connecting component can be either rigid or elastic. According to the disclosure, the rigid connection is implemented such that the end piece is attached to the connecting component with fasteners that are considered rigid – which, within the scope of the disclosure, also include expansion bolts – with or without an intermediate, rigid coupling element. In contrast, according to the disclosure, the elastic connection can be implemented by means of an elastic coupling element that is provided between the end piece and the connecting component. Depending on the configuration with / without an elastic / rigid coupling element, a multitude of additional combinations arise, in addition to the combinations mentioned above. These will not be explicitly described here in order to avoid unnecessarily lengthening the description.

[0107] The Figure 10The depicted spherical shape of the connecting components 10 is one possible design. Alternative, lighter designs of the connecting components 10 are described in the Figures 5 ff. explained in more detail.

[0108] According to Figure 1 Extending in a plane spanned by the edge tubes 8 of the respective structural element 6, each cover layer segment 14a, 14b, 14c, designed as a single-layer membrane, is connected at its edge to the edge tubes 8 of the respective structural element 6a, 6b, 6c. The cover layer segments 14a, 14b, 14c can be made, for example, of PVC or another weather-resistant and waterproof material.

[0109] In the illustrated embodiment according to Figure 1Each of the connecting components 10 of a respective structural element 6a, 6b, 6c projects a tensioning element to the connecting component(s) 10 arranged opposite each other in the same structural element 6a, 6b, 6c, thus tensioning a plane together with the edge tubes 8 of the same structural element 6a, 6b, 6c. Specifically, the tensioning element is formed by two tensioning straps 16, each of which projects to a different connecting component 10 arranged opposite each other in the same structural element 6a, 6b, 6c. The respective tensioning strap 16 is preferably length-adjustable and, at a low weight, preferably has high strength and a high modulus of elasticity. A length-adjustable Dyneema flat strap is suitable, for example. Figure 1 For the sake of clarity, only the tensioning straps 16 of a tensioning device of the structural element 6b are provided with reference numerals.

[0110] According to Figure 1The supporting structure 4 is thus, as disclosed, formed by a three-dimensional grid, the grid nodes of which, in the illustrated embodiment, are formed by the rigid connecting components 10, to which the grid sections formed by inflatable edge tubes 8 are rigidly connected via their end pieces. The supporting structure 4 is also attached to the mobile supports 2 via the rigid connecting components 10.

[0111] In the event of high potential wind loads, the mobile structure 1 can also be stabilized on the ground in the manner of a conventional tent with additional tensioning and fixing in position.

[0112] The Figures 3 and 4Figure 1 shows exemplary embodiments of similar pentagonal structural elements 6, each with connecting components 10, tensioning straps 16, and edge tubes 8. For the sake of clarity, only a minority of these elements are labeled with reference numerals. The illustrated exemplary embodiments of the structural elements 6 share the following characteristics: their pentagonal basic shape with the same angularity, a common number and type of connecting components 10, and the tensioning devices formed by the tensioning straps 16, as already shown in Figure 2. Figure 1 were explained.

[0113] For structural element 6 according to Figure 3 Two of the five circumferential sections are formed by rigid struts 20 instead of inflatable edge tubes. Furthermore, the [structure] Figure 3The structural element 6 shown does not have a membrane. In this way, the tension straps 16 are exposed. It is clearly visible that the tension straps 16 are attached to the respective connecting component 10 by means of a tie rod 22. Two tension straps 16 extend from each tie rod 22 to the opposite connecting components 10.

[0114] In both embodiments according to Figures 3 and 4 All inflatable edge tubes 8 are pneumatically connected to each other by being connected to each other via a connecting hose 24 at the respective connecting components 10. This is shown in the Figures 3 and 4 It can only be identified by the connecting component 10 located at the bottom right.

[0115] The connecting components 10 in question are designed to be non-fluid-tight, non-fluid-carrying, and non-fluid-connecting. The fluid-tight, fluid-carrying, and fluid-connecting functions are instead fulfilled by the connecting hose 24. The connecting hose 24 is therefore a separate component from the connecting component 10 in question. In other words, the connecting hose 24 is not part of the connecting component 10 according to the disclosure.

[0116] Basically, both show Figures 3 and 4 Each structural element 6, currently under construction and not yet integrated into the structure, has a compressed air supply 26 connected to an end piece of one of the edge tubes 8, so that all edge tubes 8 can be filled with compressed air simultaneously using the connecting hoses 24. On the structural element according to Figure 3Two of the five circumferential sections are not formed by inflatable edge tubes, but by rigid struts 20. The structural element 6 according to Figure 4 is formed with the cover layer segment 14

[0117] Figure 5 Figure 1 shows an embodiment of a connecting component 10 to which connecting or end pieces 18 are fully attached. Specifically, this is the connecting component 10 located directly above person P according to Figure 1. Figure 1 The connecting component 10 is arranged, to which the three edge tubes 8a and 8b are attached. For this purpose, the connecting component 10 is essentially pot-shaped and has a pot base 28, around whose essentially hexagonal circumference a pot wall 30 is arranged, formed by six mutually angled end faces 32, 34. One of the three end pieces 18 is attached to each of the three end faces 32. A tension anchor 22 of the tension straps 16 is attached to each of the two end faces 34.

[0118] Figure 6 Figure 1 shows an embodiment of a connecting component 10 to which connecting pieces 18 are only partially attached. Specifically, this is the connecting component 10 located directly to the right of person P according to Figure 1. Figure 1 is arranged, to which only the two edge tubes 8a are connected. Accordingly, the connecting component 10 has according to Figure 6 merely two end faces 32 oriented towards each other at the corner angle of the structural element 6b. Unlike the cup-shaped connecting component according to Figure 5 is that according to Figure 6The profile is formed in the form of a U-profile. The end faces 32 form the legs, and the intermediate end face 34 forms the base of the U-profile. The tie rod 22 is attached to the end face 34. Its threaded rod passes through a through-hole in the end face 34 and is secured and tensioned by a nut on the connecting component 10. To increase strength, the U-profile has two cover surfaces 36, which are bounded at their edges by the end faces 32 and 34. Both the end faces 32 and 34, as well as the cover surfaces 36, are provided with recesses for lightweight construction.

[0119] The Figure 7 shows, in a perspective top view, sheet metal sections of five different types, placed at the edge of structure 1, which are ready for joining. Figure 1 connecting components 10 to be arranged, which essentially have the same basic structure as last described by Figure 6as described. They each have an end plate with the two end faces 32 for connecting the end pieces 18 and the intermediate end face 34 for connecting the tie rod 22. In addition, they each have the two cover faces 36.

[0120] Figure 8 shows the five different connecting components 10, which are made from the submitted sections according to Figure 7 were added.

[0121] Figure 9 shows a perspective side view of the end piece 18 of the rim tube 8 according to Figure 2with an inflatable hose section 38 of the inflatable support element 12, which is fixed to the end piece 18. The end piece 18 has two axially spaced circumferential grooves 42, 44, with the hose section 38 only overlapping the axially inner circumferential groove 42. The hose section 38 is fixed in the circumferential groove 42 by a multiply wound thread 46 stretched within it. A sealant for increasing airtightness is provided at the edge ribs 40 of the inner circumferential groove 42 between the hose section 38 and the end piece 18.

[0122] Figure 10 shows a perspective side view of end piece 18 according to Figure 9, wherein the hose section (concealed) is overlapped by a shape-retaining and abrasion-resistant layer 48 of the support element 12, which is fixed in the axially outer circumferential groove 44. The shape-retaining, abrasion-resistant layer 48 is also fixed in its groove 44 by a multiply wound thread 50 stretched therein.

[0123] Figure 11 shows a longitudinal section of an end piece 18. In addition to the two in the Figures 9 and 10 The end piece 18 has circumferential grooves 42, 44 shown, in which the hose section 38 and the shape-retaining, abrasion-resistant layer 48 are each fixed by means of the thread 46, 50. Figure 11 a third circumferential groove 52, arranged even further outwards in the axial direction. In this groove is a rim 54 of a rim-side quiver 56 of a cover layer segment (reference numeral 14, cf. Fig. 1 , 4 , 12 and 13) specified. In the quiver 56, the rim tube 8 is almost completely enclosed, apart from the respective conical end sections of its two end pieces 18.

[0124] Figure 12 shows a top view of an area of ​​the connecting component 10 according to Figure 6 with the cover layer segment 14 connected to the rim tubes 8a via the quills 56. The quills 56 are predominantly cylindrical shells into which the respective rim tube 8a is inserted. The respective quill 56 encloses the support element 12 (tube section 38 and shape-retaining, abrasion-resistant layer 48) of the rim tube 8a and overlaps its end pieces 18 section by section with a radially tapered collar 58. Only a centering section of the end piece 18 protrudes through the collar 58, which is inserted into a receptacle in the end face 32 (not shown).

[0125] The function of the quiver 56 is illustrated Figure 13The quiver 56 has a lateral zipper 60 along its entire length, providing a closable access for the lateral insertion of the rim tube 8a. This allows the cover layer segment 14 to be attached to the rim tube(s) 8 by opening the zipper 60, slipping the quiver 56 laterally over the rim tube 8, and then closing the zipper 60 again. The cover layer segment 14 is also axially fixed to the rim tube 8 by the collar(s) 58. Alternatively or additionally, a third circumferential groove can be provided on one of the end pieces (see Figure 1). Fig. 11 The quiver with zipper 60 allows the cover layer segment 14 to be attached to the edge tube(s) 8 without having to disassemble or relax the structural element 6.

[0126] Figure 14 shows a longitudinal section of the edge tube in an area of ​​its connection to the connecting component 10 according to Figure 5, in perspective view. The end piece 18 is constructed as a cap-shaped, conical hollow body, which is penetrated in the axial direction from the interior of the support element 12 to a compressed air connection 62 by a compressed air channel 64. A hose adapter 66 is attached to the compressed air connection 62, to which the connecting hose 24 shown in the previous figures or the compressed air supply 26 (see e.g. Fig. 3 ) can be connected. The compressed air connection 62 passes through a through-recess 72 formed in the end face 32, which is penetrated by the compressed air connection 62 and together with it enables a kind of pre-centering of the end piece 18 on the connecting component 10.

[0127] It should be mentioned again that the connecting component 10 in question is not designed for fluid tightness, fluid connection, or fluid guidance. The fluid-tight, fluid-guiding, and fluid-connecting functions between the end pieces 18 pre-centered on the connecting component 10 are instead fulfilled by the connecting hose 24, which is not part of the connecting component 10.

[0128] On its inner side, the end piece 18 has reinforcing struts that make it more pressure-resistant. At the base of the compressed air connection 62, the end piece 18 is radially extended and forms a concentric contact surface that is in contact with the end face 32 of the connecting component 10. Six blind holes 68 with internal threads are formed in the contact surface, concentric to the compressed air connection 62. The end face 32 thus has aligned through holes 70, which are penetrated by screws (not shown) that engage in the blind holes 68. In this way, the respective end piece 18 is pre-tensioned in its predetermined position on the end face 32, and the corner angle assumed by the edge tubes 8 is also predetermined. According to the disclosure, this type of connection is referred to as a rigid connection, since no elastic coupling element is interposed, but rather the connection is direct, solely via the screws.Conversely, if an elastic coupling element is interposed, the connection is referred to as an elastically designed connection according to the disclosure.

[0129] Figure 15 shows a perspective top view of the end piece 18 according to Figure 14 .

[0130] Figure 16 Figure 1 shows a perspective top view of a mobile structure 101 according to a second embodiment. This differs from the mobile structure 1 according to the first embodiment, in which the connecting components 10 are clamped against each other via the clamping devices 16 in order to stiffen the respective structural element 6 (see in particular Figure 1). Figure 1 and 3 ), in the case of structure 101, the deck layer segment 114 is essentially used for bracing and thus stiffening the structural element 106.

[0131] The membrane-like cover layer segment 114 has a central, large-area surface section 77 and several peripheral, approximately circular-segment-shaped surface sections 78 – so-called "flaps". The central surface section 77 is bounded at its edges, i.e., towards each peripheral surface section 78, by a force transmission element 74. The force transmission element 74 is designed as a tensile-resistant webbing, for example, as a high-strength Dyneema flat webbing, and extends between adjacent corner sections 80 of the cover layer segment 114 in a concave shape, i.e., curved towards the center of the surface section 77 of the cover layer segment 114.

[0132] The central, large-area surface section 77 of the deck layer segment 114 is designed in particular in the form of a pentagonal sunshade with concave edge sides.

[0133] The corner sections 80 are connected to the connecting components 10 of the structural element 106 via tension elements 82 and are prestressed.

[0134] This connection of the cover layer segment 114 under prestress, as well as the concave force transmission elements 74, enable the approximately flat position of the central, large-area surface section 77 of the cover layer segment 114.

[0135] The pre-tension can be varied and in practice adjusted / dimensioned so that no or as few wrinkles as possible form on the large surface area section 77 of the cover layer segment 114.

[0136] Figure 17 shows the in Figure 16 , or in Figure 18 defined partial section A - A of the edge tube 8 and the attached cover layer segment 114, in order to illustrate the section-by-section construction of the cover layer segment 114. The edge tube 8 has a - in particular already explained (cf. Fig. 11) - two-layer construction with the radially inner, airtight tube section 38 ("Biadder") and the radially outer, abrasion-resistant layer 48. The rim tube 8 is inserted into the quiver 156. Unlike the quiver 56 shown in Figure 36, the outer surface of the quiver 156 is designed without a zipper. Accordingly, the rim tube 8 was inserted axially into the quiver 156 instead of laterally.

[0137] The quiver 156 has according to Figure 17 a short, radially outward-pointing collar that extends axially along the quiver 156 and carries a zipper 72 along its entire length. The edge surface section 78 of the cover layer segment 114 is attached to the quiver 156 via the zipper 72.

[0138] It should be emphasized that the edge surface sections 78 are connected to the quiver 156 in a manner that is almost stress-free or at least stress-reduced, as intended.

[0139] In particular, this is achieved by the respective concave force transmission element 74, which is designed and configured to influence the force flow / force transmission in the cover layer segment 114, as shown by Figures 20 and 21 This will be explained in more detail below.

[0140] The power transmission element 74 is according to Figure 17 sewn on the underside or inside with the central large-area surface section 77 and with the edge surface section 78.

[0141] Figure 18 Figure 1 shows the edge tube 8, the quiver 156 and the attached cover layer segment 114 with the edge surface section 78, the force transmission element 74 and the central surface section 77 in a perspective view from above or from outside the structure / tent 101. For better orientation, the definition of the partial section A - A is shown.

[0142] Figure 19The cover layer segment 114, connected to edge tubes 8, is shown in a view from below, or from inside the structure / tent 101, in the area of ​​one of the corner sections 80. The corner section 80 ends according to... Figure 19 The two force transmission elements 74 of the adjacent edge tubes 8. End pieces 18 of the edge tubes 8 are connected to the connecting component 10 (not shown, see below). Fig. 16 The force transmission elements 74 each have a sewn loop 86 at their ends. The loops 86 are threaded through an eyelet-shaped connecting element 88, in the illustrated embodiment a stainless steel shackle. The tensioning element 82 is attached to the shackle 88, via which the corner section 80 is connected to the connecting component 10 under preload.

[0143] Figure 20 shows one of the structural elements 106 of the building 101 according to Figures 16 to 19with an acting load F, for example a wind load. The deck layer segment 106 is prestressed at the connecting components 10 via the tensioning elements 82. The prestressing and the concave straps / force transmission elements 74 ensure that the deck layer segment 114, more precisely its central surface section 77, is taut and wrinkle-free without any further aids.

[0144] The power flow is according to Figure 20 as follows: The wind load F acts essentially on the central, large-area surface section 77 of the cover layer segment 106.

[0145] The wind load F is transferred proportionally (b) to the five force transmission elements 74 via the textile of the surface section 77.

[0146] The respective force transmission element 74 transmits a force proportionally (c) to its two loops 86 and the shackles 88 located there.

[0147] The shackles 88 and the attached tensioning element 82, which are assigned to the respective force transmission element 74, transmit a force proportionally to the respective connecting component 10.

[0148] The respective connecting component 10 transmits a force proportionally (d) to the two end pieces 18 of the rim tube 8.

[0149] The two end pieces 18 transmit a force proportionally, predominantly axially (e), into the inflated rim tube 8.

[0150] In this way, the inflated edge tubes 8 are predominantly subjected to axial loads, that is to a lesser extent to transverse loads or bending loads.

[0151] Because the edge surface sections 78 are connected to the socket 156 almost without stress or at least with reduced stress, and the force flow as described above (b, c, d, e) takes place via the force transmission elements 74, predominantly bypassing the surface sections 78, only a reduced shear force is introduced laterally at the edge tube 8 via the socket 156.

[0152] The risk of a particularly critical transverse or bending load on the inflated edge tubes 8 is thus reduced.

[0153] Accordingly, it shows Figure 21 schematically the direction of the reaction forces on structural element 106, which result from the according to Figure 20 The force flow described above results. Due to the force flow being deflected at the force transmission element 74 as shown, the edge tubes 8 are predominantly subjected to axial shear stress. Their radial stress, which entails an increased risk of fracture, is reduced.

[0154] The mobile structure revealed may have a supporting structure formed from other polygons or from mixed forms of different polygons.

[0155] Revealbart is a mobile structure with a multitude of polygonal structural elements bounded by textile, inflatable edge tubes, whose end sections are connected to connecting components, so that the connecting components and the edge tubes form a three-dimensional grid as a supporting structure, which is formed from lightweight pneumatic and sufficiently stiff grid struts - the edge tubes - and from sufficiently stiff nodes - the connecting components - thus giving the structure a low weight and yet a high load-bearing capacity and high stiffness.
