Definitions

  • the invention relates to a component and a method for its production.
  • the component can be used as a wall element or as a ceiling element. It is factory made and transported as a prepared plate-shaped component to the site for installation there.
  • the component preferably has a rectangular, in particular square shape. It can have a curved or arched shape, even with Eckeren.
  • the edge length of the component can each be a few meters.
  • the component has an attachment shell with a first concrete layer and a support shell with a second concrete layer. With the help of several connecting bodies, the attachment shell is connected to the carrier shell.
  • the front shell is mainly used to determine the appearance of the device and to ensure weather protection as a building shell, while the tray depends on the required statics to support the introduced into the device forces. Insulation material may be present between the front shell and the tray.
  • a component that can serve as a wall or ceiling element is, for example, from DE 100 07 100 A1 known.
  • lattice girders made of stainless steel, black steel or galvanized steel are used.
  • Such steel connecting body can absorb very well introduced into the front shell forces and supported on the tray.
  • steel joint bodies have the disadvantage that the production of steel requires a lot of energy and high costs.
  • cold bridges arise between the front shell and the tray.
  • a similar designed as a conversion element components is off DE 100 59 552 A1 known.
  • Double claw elements are used to connect the attachment shell with the support shell. This should allow a greater distance between the facing shell and the tray to be able to make the insulation layer thicker.
  • the double claw elements are preferably made of metal and in particular of steel. This should result in the same thermal expansion coefficient for the claw elements as for the support shell, if this consists of reinforced concrete.
  • a tubular element as a sandwich composite panel is also made DE 29 39 877 A1 known.
  • linear anchor elements are used in various configurations.

  • These connecting bodies may be made of a plastic-reinforced fiber-reinforced composite material.
  • EP 0 051 101 A1 is a structural element of textile concrete with a first layer of concrete and a second layer of concrete can be connected to each other via concrete ribs. All concrete sections are reinforced near the surface with a fiberglass textile reinforcement.
  • the component has an attachment shell with a first concrete layer.
  • a textile reinforcement is arranged in the first concrete layer.
  • the textile reinforcement preferably extends in a plane parallel to the outer surface of the facing shell.
  • the textile reinforcement can be embodied, for example, as a flat knitted fabric, woven fabric, fabric or scrim, the spatial extent of which in an extension plane is preferably greater than in the spatial direction perpendicular to the extension plane.
  • the dimensioning of the reinforcement depends on the static requirements.
  • the textile reinforcement can therefore have a substantially two-dimensional shape. But it is also possible that the textile reinforcement has a three-dimensional shape.

  • the static load of the device is absorbed and supported by the support shell.
  • the spaced apart facing shell normally serves to accommodate lower loads and in particular to improve the visual impression of the device and the weather protection. It covers, for example, an insulating layer arranged between the carrier shell and the facing shell. Due to the flat and lightweight textile reinforcement in the attachment shell, this can be made very thin and therefore very light.
  • the connecting bodies have a rigid three-dimensional shape and are formed by a three-dimensional textile grid structure, which is in particular free of metallic elements.
  • the connecting bodies are therefore not designed as solid closed body, but as a grid body with a plurality of openings or meshes.
  • the connecting bodies are therefore very light. They have a poor heat conduction and therefore form no cold bridges between the front shell and the tray.
  • such connection bodies of a three-dimensional textile grid structure are easy to manufacture and also easy to handle in the manufacture of the device.

  • the textile grid are brought into the desired three-dimensional shape and fixed.
  • the connecting body connects very well with the two concrete layers, in which the connecting body is poured. In order to predetermine the desired position of the connecting body before casting the concrete layers, this can be very easily connected to the textile reinforcement, for example through tie wire or cable ties, due to its lattice structure.
  • the textile grid structure may comprise, for example, glass and / or carbon fibers.
  • Each connecting body preferably has a constant cross-sectional contour in its extension direction.
  • the connecting body is thereby produced as a longitudinal element and can be easily cut in the required length for the device.
  • each connecting body has at least two grating sections which extend in different spatial planes.
  • two adjacent grid sections are aligned at right angles to each other.
  • each connecting body has a first grid section and a second grid section, which are arranged parallel to one another and at a distance from each other.

  • the third grid section can very well support the forces introduced into the attachment shell in its plane of extent and transfer it into the carrier shell.
  • the reinforcing element is optional. It may preferably extend along the entire area of the two grid sections of the two connected connection bodies.
  • the third grid sections of the two connecting bodies are the same size. If two connecting bodies are arranged in such a manner, the respective first grid sections extend away from the assigned third grid section in opposite directions. The respective second grid sections also extend away from the respective third grid section in opposite directions.
  • There is a total of a cross-sectional I-shaped connector body assembly whose cross-sectional shape can also be referred to as a double-T-shaped.
