Definitions

  • the invention relates to a structure for building technology, in particular to build structures such as building-like facilities, Exhibition stands, canopies or the like, with several on one Underlying and load-bearing supports that are formed by airtightly closed hollow bodies, the one Have wall made of flexible material and for preservation a rigid structure are filled with compressed air, the Supports are at least partially designed as pillars that have a vertical support column.
  • Such a structure can be found in EP-A-0 403 981. It there is part of a construction that the effects from permanent Loads, traffic and / or payloads and receives one Forwarding document.
  • exhibition stands or roofing is the basis mostly formed by a floor that is outdoors or in a Building.
  • Pneumatic bodies are used as supports used, their transport and storage in a depressurized state can be done, it being the flexible walls of the hollow body allow the supports to be folded up or folded down.
  • the supports can be in their final use form still be awarded on the spot by being there with Compressed air. They are cylindrical, in cross section circular longitudinal elements formed.
  • the inside pressure the hollow body ensures an overall rigid structure, the weight of the individual supports is proportionate overall is low, so that it is inflated still handle. It would be conceivable for the individual supports filled with the intended compressed air volume ex works and then hermetically seal the hollow body.
  • the supports Preferably however, the supports have suitable filling openings, which allow inflation or deflation as required, to make handling as flexible as possible. In this case, too, pressure can be applied as required take into account the existing load.
  • the supports are as resistant to pressure, buckling and bending as possible should, it is the object of the present invention to create the structure while maintaining a simple Manageability can take higher loads.
  • the support column is designed as a concentrically bulged longitudinal element, whose diameter from both end areas to the longitudinal center increases.
  • All supports are expediently designed as pillars, which is preferably at least partially a vertical support column have, whose lower end is on a pad supports and two cantilever arms are provided at the upper end region are sloping, i.e. sideways and at the same time extend above, expediently such that the pillar bifurcates in the upper area and has an overall Y-shape.
  • the props filled with compressed air mainly take compressive forces on.
  • the supports via flexible traction elements such as traction cables to the base to relax.
  • the possibly existing cantilever arms respective pillars are preferably above such tension elements in connection with each other.
  • Handling and assembly is particularly easy when a respective pillar formed as a coherent component and is preferably a one-piece unit represents. In this case, one is usually sufficient Filling opening to supply compressed air as required can.
  • the supports are available for fastening loads to be carried expediently via fasteners, which act as user elements can be trained so that there is a link by means of common connecting elements such as belts or Ropes can be made.
  • a load to be carried can be formed by a roof that is composed of individual roof elements attached to the Supports are attached.
  • This can be, in particular area roof elements that e.g. a Have a triangular contour. They are like the supports Roof elements expediently as under an internal pressure standing, airtight hollow body.
  • wall or floor elements can be attached to the structure be present that have an areal extension and also as an airtight one filled with compressed air Hollow bodies can be formed. Leave with their help completely closed buildings in particular create.
  • the material for the supports is particularly flexible Plastic material provided that is sufficient Compressive strength.
  • fiber-reinforced plastic material for example aramid-reinforced Nylon.
  • the supports consist of a plastic fabric that at least on one and preferably on both sides is provided with a gas-tight coating.
  • Wall and floor elements come especially a so-called Two-wall plastic fabric for use, in which two Plastic fabric walls are connected to each other via threads, so that there is a certain gap. Leave with it especially those hollow bodies that are realized in the under Have a high degree of shape fidelity, so that there are large-scale ceiling, wall and floor elements let realize that over relatively level Have floor space and hardly bulge.
  • Said structure 1 comprises a plurality of supports 2, which in vertical alignment side by side on a base 3 are set up.
  • the base 3 is the floor in the present case an exhibition hall.

  • the supports 2 are used for load absorption. Are exemplary two types of loads are present, supported by supports 2 be worn.
  • One type of load is one of a plurality of roof elements 4 composite roof 4 'that to the upper ends of the supports 2 is suspended and with Distance above the base 3 area-like over this extends. 6 are only for the sake of clarity some of the roof elements 4 are shown, which are flat Have a shape and are triangularly contoured in the present case. Man could also call them disc-like elements.
  • Another type of load consists of one or more wall elements 5 used to form partitions or side walls 5 ' are usable and between the upper end of the concerned Support and the base 3 run vertically.
  • the wall 7 (Fig. 4, 5) consists of flexible material and which is used to obtain a rigid structure are filled with compressed air.
  • Each prop 2 is therefore an inflated flexible hollow body that is when the interior 8 is vented, fold it up easily, curled up or otherwise folded to a smallest possible transport or storage volume receive.
  • the supports 2 are designed as pillars 12. In a preferred design, they initially have a vertical support column 13 linear extension with its lower end 14 is placed on the base 3. At the upper end region 15 of the support column 13 close two Cantilever arms 16 of linear extension, each both run sideways outwards as well as upwards, with increasing height from the vertical axis 17 of the Remove support column 13. With regard to this vertical axis 17 these obliquely extending cantilever arms 16 are mirror-symmetrical arranged so that they are diametrically opposite and the pillar 12 has an overall Y-like shape. Of the So pillar 12 bifurcates at the upper end region 15.
