Definitions

  • the invention relates to a wall element as a prefabricated component for buildings.
  • a wall element as a prefabricated component for buildings.
  • the finished part is manufactured in a production plant and then to the location transported, on which the building is built in prefabricated construction. Accordingly, there is a requirement that such wall elements have a simple constructive They should have a structure and be easy to manufacture, even in large ones Quantities can be produced.
  • a base plate is made of Liapor, i.e. made of concrete, the expanded clay contains.
  • This base plate is connected to a mounting plate that e.g. as Liaver intent is known.
  • This building board contains cement glue Recycled glass with air pockets.
  • a composite wall element which is a base plate contains concrete, on which a polystyrene plate is pegged.
  • the disadvantage is here that no moisture diffuses through this wall element can and at the boundary layer between polystyrene plate and concrete slab moisture problems can arise.
  • This task is solved for a wall element as a prefabricated component for buildings, wherein the wall element contains a first layer of lightweight concrete, the surface is directly connected to another layer.
  • This additional layer contains foam balls embedded in a cement matrix.
  • the wall element has due to the embedding of foam balls a favorable thermal insulation value. Furthermore, the total weight of the wall element low, making it particularly favorable for prefabricated buildings of buildings.
  • a particular advantage is the fact that as a result of the used cement matrix moisture compensation over the cement paste can and, unlike the composite system with polystyrene plate, a moisture problem at the boundary layer between the layer of lightweight concrete and the other layer does not occur.
  • foam balls are expanded Polystyrene balls or styrofoam balls are used.
  • Polystyrene and polystyrene are cheap bulk plastics that are easy to manufacture and cheap Have insulation properties. This material gives the additional layer the necessary favorable thermal insulation value. Because of the use of these plastics in the form of small balls, these do not form a diffusion barrier, so that a moisture balance can take place over the balls.
  • the foam balls preferably have a diameter of 0.5 to 2.5 mm, preferably 0.5 to 1.5 mm. With such a size, the Mix the foam balls lightly with the cement matrix so that the mixture is easy to process.
  • An exemplary embodiment is characterized in that the further layer 70 contains up to 90 percent by volume of foam balls, preferably 80 to 90 By volume. In this way, the specific weight of this is further Layer significantly reduced, making the entire wall element at favorable constructional values has a low weight.
  • a wall element 10 which is a base plate as the first layer 12 and contains an outer plate 14 as a further layer.
  • the base plate 12 consists of light concrete and contains a mixture of light sand, cement and water and expanded clay.
  • the base plate typically has a thickness L1 of 10 to 30 cm.
  • the outer plate 14 contains foam balls embedded in a cement matrix 16.
  • the thickness of the outer plate 14 is typically in the range of 1 to 30 cm, preferably in the range of 5 to 20 cm.
  • the foam balls 16 consist of expanded polystyrene balls or styrofoam balls and have a diameter of 0.5 to 2.5 mm, preferably 0.5 up to 1.5 mm.
  • the outer plate 14 contains about 70 to 90 percent by volume Foam balls 16 and thus has a low specific weight.
  • the two Layers 14 and 12 are in a production plant for prefabricated components wet-on-wet concreted together and hardened together. You are thus imagining uniform component.
  • the wall element 10 typically has a thermal insulation value or U value of 0.2 to 0.6 W / m 2 K, preferably 0.24 to 0.35 W / m 2 K. It is therefore particularly suitable as an outer wall in a building ,
  • a particular advantage of the wall element 10 is that it is breathable and moisture is allowed to pass through the cement matrix.
  • the example shown in FIG. 1 can also be expanded.
  • the layer 12 on a board preferably a wooden board, a particle board or a cement chipboard and be connected to it.
