Definitions

  • the invention relates to a lightweight component which consists of an airtight and pressure-resistant coated support fabric.
  • the support fabric is made of a flexible composite film which has a textile web made of plastic threads, which is coated on both sides with plastic.
  • Two plastic film blanks welded or glued to one another at their edges are filled with a semi-hard or still elastically deformable plastic foam body, which is produced by foaming the plastic material directly into the cavity.
  • This lightweight component has the disadvantage that metal molds are required for its production, which take up the high pressures that occur in the plastic foam filling.
  • metal molds are required for its production, which take up the high pressures that occur in the plastic foam filling.
  • its shape can no longer be changed or folded into a small space for transport.
  • Another known lightweight component is composed of two identical parts. Each part has a fabric underlay on which a row of parallel strips of polyurethane foam of triangular, rectangular or trapezoidal shape is made by means of a fabric sheet is attached according to the cross section. The fabric web is connected to the fabric underlay by seams between the individual strips. The two parts are now placed on top of one another, their strips interlocking like teeth. Now the lightweight construction element is provided with two cover layers made of fabric and soaked with liquid plastic, to which a catalyst for hardening the plastic has been added.
  • This lightweight component can also not be folded when it is no longer to be used.
  • a lightweight construction element provided with glass fiber reinforced polyester plates in which the space delimited by the polyester plates consists of a framework structure in the form of coils made of metal wire or of glass fiber reinforced polyester or of a mesh consisting of such coils.
  • the individual coils are embedded in a fabric layer soaked in polyester.
  • cushion elements have been proposed for a variety of technical purposes. These cushion elements were produced from a film material, the film edges being connected to one another by sewing, gluing or welding.
  • Such pillow elements can generally be folded together when not in use in a small space, but they have the disadvantage that their shape depends to a certain extent on the pressure of the pumped-in air or the like. As a result, they cannot be used as plate-shaped or shell-shaped lightweight components have precisely specified dimensions formed, especially since larger areas inevitably bulge under the pressure of the pressed-in pressure medium.
  • the invention aims to eliminate the disadvantages of the known embodiments and to create a lightweight construction element of the type outlined which, despite its low weight, has great dimensional stability and is simple in its construction and inexpensive to manufacture, for which no expensive ones are involved Metal molds should be required.
  • the surfaces of the lightweight component should not bend outwards when the interior is pressurized.
  • the support fabric consists of an uncut velvet fabric, the interior of the velvet fabric being pressurizable by the airtight coating.
  • the vertical threads connecting the two fabric webs keep the two fabric webs at a predetermined distance when the interior of the velvet fabric is filled with a pressure medium.
  • a gaseous or liquid medium is used as the pressure medium, it is possible to relieve the pressure in the interior of the lightweight component when the latter is no longer to be used and then to fold the lightweight component together. This makes it possible to save storage space or transport space.
  • the assembly and disassembly of the lightweight component is extremely simple and can easily be carried out by auxiliary staff without special training.
  • a curing plastic foam can be used as pressure medium. On the one hand, this ensures sufficient dimensional stability of the lightweight component and, on the other hand, a relatively low weight of the same.
  • the invention provides that at least one feed pipe protrudes into the interior of the lightweight component. This ensures the supply line and an even distribution of any pressure medium. It is also possible to connect several lightweight components in series using the supply pipes and to feed them from a single pressure medium source.
  • the lightweight component according to the invention can be used to advantage in a wide variety of fields. It can be used in the manufacture of self-supporting halls, tents, flexible partition walls of all kinds, formwork, cladding of containers, round silos, formwork elements for the construction industry, etc. However, the use of the lightweight component as packaging material is also contemplated, especially since here it is possible to transport the empties back in a cost-saving manner when folded.
  • the distance 5 of the upper fabric web 1 from the lower fabric web 2 can preferably be between 2 and 20 mm.
  • the two fabric sheets of the lightweight component are provided with an air-impermeable coating 6.
  • This coating which is generally a vulcanized-on rubber coating, can be impact-resistant, non-slip, smooth, rough, cold or heat-resistant, chemical-resistant, insulating, etc., depending on the requirements.
  • the fabric webs of the lightweight construction element are connected to one another by seams 4 on both sides.
  • the air-impermeable coating 6 it is possible to pressurize the interior 7 of the lightweight component, thereby making the lightweight component a stable structure. Gases such as air, helium, etc. or liquids are primarily suitable as pressure medium. However, it is also possible to fill the interior 7 with a foam, for example with polyurethane foam, which hardens itself after being filled.
  • the two lightweight components 10 and 11 are connected to one another by an adhesive layer 9. Instead of this adhesive layer 9, however, seams can also occur. Pressurize the interior of the two lightweight components 10 and 11 at the same time To be able to, these interiors are interconnected by means of an angularly bent tube 12. Another straight pipe 12 ′ serves to introduce the pressure medium or the foam into the interior of the lightweight component 11.
  • the hall shown in FIG. 4 made from a lightweight construction element according to the invention, has a semicircular cross section, with flanges 14, which rest on the foundation 13, being attached to the ends of the curved lightweight construction element.
  • the two flanges 14 have cover strips 16 on their upper side, which are held on the foundation 13 by means of screws 17.
  • a pressure medium is also supplied to the interior of the lightweight component via a line in which a manually operable valve 8 is installed.
  • This valve 8 can be connected via a supply line 18 to a pressure medium source, for example to a pump or to a compressed air bottle.
  • the pressure medium contained in the lightweight component can be released into the open via the valve 8.
  • the hall shown can be open on its front side, since in contrast to an air-filled hall no airlock is necessary here.
