Definitions

  • Pneumatic known components e.g. for sailboat hulls consist essentially of a tube to be acted upon by compressed air rotating body. In terms of flow, these hull shapes have a poor efficiency and, due to the design, have no directionally stable straight-line running, which ultimately impairs the sailing properties.
  • Another disadvantage is that these pneumatic body must be subjected to high internal pressure to stay kink-resistant.
  • the invention is now based on the problem of providing a pneumatic body which avoids the disadvantages shown on the two product examples representative and also allows further advantages.
  • the inner forming profile is disposed within the cavity forming sheath.
  • the design limit for the use of an inner shaping profile is achieved when the cavity-forming casing can be formed by pressurization to a rotational body and the diameter is greater than the height or width of the inner shaping profile.
  • the internal shaping profile ensures that the pneumatic body remains kink-resistant, even at low internal pressure in the cavity-forming shell.
  • contour profile of the inner shaping profile In conjunction with the appropriate choice of material for the cavity-forming shell and a specified internal pressure, creates a planned three-dimensional shape of a pneumatic body.
  • different product requirements such as pedestrian bridges or boat hulls of different load bearing capacity, can be realized.
  • the inner forming profile runs horizontally in the cavity-forming casing, the inner forming profile is less exposed to compressive and tensile loading, since now the pneumatic mode of action of the cavity-forming casing is more pronounced.
  • the internal forming profile is designed according to the product requirement.
  • the inner forming profile may e.g. when used in a membrane pad, be formed from a thin Plexiglas disk or frame.
  • the inner forming profile is subjected to high pressure and pressure
  • the static tasks are defined by both functional elements, the inner shaping profile and the cavity-forming sheath, in their dependent operative connection.
  • the inner shaping profile When using a flat, dense plate material for the formation of the inner shaping profile, and a material for the cavity-forming shell with mirror-symmetric blank, two equal-sized cavities, which extend to the left and right of the inner shaping profile.
  • the uzefbrm centressprofil can be formed of a thin material and still be subjected to a large pressure load, since the inner shaping profile is stabilized and held by the two air pressure pads, which are located on its two sides in its central position.
  • the inner shaping profile In a different pressurization of the two cavities with gas or air, which consists of a flat plate material internal shaping profile must be structurally stronger, creating a different surface pressure.
  • the internal shaping profile prevail in both pneumatic bodies identical pressure conditions.
  • the internal forming profile is responsible for two major design functional requirements. One is responsible for the definition and shaping of the circumferential contour of the pneumatic component in a plane and determines depending on how e.g.

  • Today's foil cushions consist of two or more layers of film forming the void-forming envelope.
  • the cavity-forming sheath () no longer needs to be tensioned from outside by a tensioner frame, but can be inserted into existing or newly designed roof and façade elements through the use of an interior shaping profile such as a glass sheet.
  • the inner forming profile is formed in this application of a transparent plastic plate or a frame construction. For energy-related reasons, it is advantageous if the internal shaping profile is formed from transparent web or double-web plates.
  • the films forming the void-forming shell can be sealed airtight to the transparent plastic panel or the surrounding frame structure.
  • the single-layer or multi-layer films used outside the inner molding profile or the frame construction are welded together.
  • the encircling frame construction has on its inner side receiving guides for receiving transparent plastic plates and films with or without arranged below net mesh made of stainless steel wire or plastic.
  • the middle film is welded to the inner and outer film and the fabric is attached centrally to the frame construction.
  • the inventive design of the film cushion with the inner shaping profile allows integration of the foil cushion in the roof or facade construction, without causing cold spots at the junctions.
  • the film cushions according to the invention are particularly suitable for industrial production with corresponding fabrication.
  • the upper film of the cavity-forming sheath for the foil cushion is formed by a preformed, solid, transparent plastic element and is subjected to air pressure as in the flexible embodiment.
  • the void-forming shell that forms the boat consists of two different materials.
  • the void-forming shell that forms the hull consists of a flexible film with or without a textile fabric.
