Definitions

  • the invention relates to a building envelope element with a foil cushion which comprises an outer foil layer forming the outside of a building envelope and an inner foil layer forming the inside of a building envelope, which between them form at least one essentially fluid-tight closed cavity in which a fluid medium, in particular Air, is included, and with a reinforcing element.
  • Building envelope elements are known to be used in foil roof systems and foil facade systems. These foil roof and foil facade systems are preferably used in the construction of commercial buildings such as sports stadiums, event centers or shopping centers. These buildings, which usually have very large roof and bevel surfaces, take advantage of the advantages associated with foil roofs or foils facade systems, such as lightness and light permeability or the ability to design the color scheme.
  • film cushions consist of two outer film layers which are connected to one another in a substantially fluid-tight manner and which are usually welded to one another along their edges in order to form an essentially fluid-tight closed cavity between them.
  • this cavity is filled a fluid medium, in particular a gas such as air, is introduced, as a result of which the film layers are tensioned accordingly and the film cushion is given its intended shape.
  • the film cushions are usually equipped with a device for supplying a fluid medium, via which, for example, the air pressure in the film cushion can be regulated.
  • the fluid medium introduced into the film cushion is not only used to shape the cushion, but also for thermal insulation, which is another advantage of the film system.
  • the document DE 202 17 990 U1 discloses a building cladding element according to the preamble of claim 1.
  • the reinforcement element receives its load-bearing function through the coupling with the outer film layer via the pressurized fluid medium.
  • the pressure formation in the chambers is therefore decisive.
  • the level of the first and second pressure and / or the ratio of the first and second pressure are designed so that the film layer relieves the outer film layer, in particular in the case of outward suction effects, by removing part of the stress on the outer film layer via the pressurized fluid Medium is transferred to the film layer.
  • the building envelope element according to the invention can be developed in that the film layer consists, at least in sections, of a material that allows shape changes, in particular an elastic material.
  • the load transfer from the outer film layer via the fluid medium to the film layer is supported by the fact that the reinforcement element is not dimensionally stable, but can adapt its shape and for this purpose consists of an elastic material.
  • the outer film layer which can then consist, at least in sections, of a material that allows shape changes, in particular an elastic material.
  • the load transfer is also supported if the outer film layer is not dimensionally stable, but can adapt its shape and for this purpose consists of an elastic material.
  • the film layer is curved, specifically in the same direction as the outer film layer, which is usually curved outward.
  • the curvature curves of the film layer and the outer film layer should be similar to one another. This is advantageous for particularly effective load transfer.
  • the reinforcement element is designed as a further film layer.
  • This has the advantage that, for example, the same material can be used for the two outer film layers and the reinforcing element to simplify production.
  • the inner film layer can also consist of the same elastic material as the outer film layer and / or the reinforcing element.
  • the division of the film cushion into two chambers by the middle film layer also produces a two-layer thermal insulation and thus an improvement in the insulating effect of the film cushion overall, in that the second chamber in particular makes a contribution to thermal insulation.
  • the second chamber has a smaller volume than the first chamber.
  • the building envelope element according to the invention is further characterized by the fact that the tension in the reinforcement element is over 100% of the tension in the outer film layer.
  • This tension ratio supports the load transfer from the outer film layer to the reinforcement element.
  • the tension in the reinforcement element can possibly also be well over 100% of the tension in the outer film layer.
  • the inventive construction of the foil cushion with the reinforcement element in the form of a further foil layer makes it possible to implement the reinforcement in a technically new way and at the same time significantly reduce the use of material and the associated manufacturing costs of the foil cushion.
  • Figure 1 shows a building envelope element according to the invention schematically in cross section.
  • FIG. 1 a building cladding element 100 according to the invention is shown, which can form a foil roof or foil facade system with a large number of other building cladding elements according to the invention.
  • the building enveloping element 100 consists of an outer film 101, an inner film 102 and a reinforcing element 107.
  • the reinforcing element is essentially flat, i.e. it has a significantly greater extent in length and width than in height.
  • Both the reinforcement element 107 and the outer film 101 are preferably made of an elastic material that allows changes in shape of the reinforcement element 107 or the outer film 101.
  • the reinforcement element 107 is also designed as a film.
  • the outer film 101, the inner film 102 and the reinforcing element 107 are welded to one another at their edges 103 and 104, so that between the reinforcing element 107 and the inner film 102 a first essentially fluid-tight closed chamber 108 and between the reinforcing element 107 and the outer Foil 101 a second, essentially fluid-tight closed chamber 109 is created.
  • the fluid medium in the first chamber 108 has a first pressure applied to it.
  • a second pressure is applied to the fluid medium in the second chamber 109.
  • the pressure on the fluid medium in the first chamber 108 is greater than the pressure on the fluid medium in the second chamber 109.
  • the second chamber 109 also has a smaller volume than the first chamber 108.
  • a supply device (not shown) can be provided, which is preferably connected to the two chambers 108, 109 via pipe or hose lines.
  • the outer film 101 is curved outward, such as Figure 1 reveals.
  • the inner film 102 is curved in the opposite direction, namely in the direction of the interior of the building.
  • the reinforcement element 107 which also consists of a film material, curved in the same direction as the outer film 101.
  • the curves of the outer film 101 and the reinforcing element 107 should preferably be as similar as possible to one another.
  • the building envelope element 100 is held at its edges 103 and 104 by fastening elements 105 and 106, via which it is connected to further building envelope elements and / or a supporting structure.
  • the tension is more than 100% of the tension in the outer film 101. It can be seen from this that the reinforcement element has a significant share in the load transfer.
  • the tension in the reinforcement element 107 can, however, in particular in the case of a load, also be well over 100% of the tension in the outer film 101. This is the case when a large part of the loads are removed via the reinforcement element 107 and failure of the outer film 101 is thus prevented.
  • the two fluid-filled chambers 108 and 109 can contribute to the thermal insulation effect of the building envelope element 100.
