Definitions

  • the invention relates to composite components made of a core layer made of polystyrene particle foam and at least one top layer made of cement mortar and a method for producing the composite components.
  • DE-A 1 609 631 describes a building board that has one Core of a porous material, e.g. a polystyrene foam, and a layer of gypsum.
  • the building board is manufactured by Applying a gypsum slurry to a board made of the porous material so that the gypsum enters the surface cavities of the board flows.
  • this only results in a superficial, loose connection between core layer and cover layer.
  • the invention was therefore based on the object of composite components to provide, which do not have these disadvantages.
  • the cement mortar is preferably first poured into the mold, then the foam particles are added and the mold closed.
  • the particles expand due to evaporation of the blowing agent still contained in them.
  • These expanding particles exert pressure at the interface on the mortar layer.
  • the liquid cement gives way to this Pressure out by partially in the gusset of the foam particles penetrates so that a smooth transition between the layers A and C arise. At the same time, but a little slower, this happens Sintering of the foam particles and setting of the cement mortar.
  • the inventive method allows considerable time and Cost savings in production without the use of adhesives Need to become.
  • the composite components according to the invention have the following structure: A top layer is included the core layer connected by the intermediate layer. There is a noticeable penetration in the intermediate layer the pre-expanded particles with the cement mortar, penetrated into the gaps between the foam particles is, at a time when the two materials are still were not sintered or solidified. In the subsequent Sintering the foam particles and setting the cement mortar the cement mortar remains in the interlayer in the gusset volume and harden there. This bonding and sintering into each other penetrated materials cause strong consolidation the intermediate layer and a good connection of the core layer with the top layer or the top layers without the use of adhesives.
  • the thickness of the composite components according to the invention can vary Application area fluctuate within wide limits, preferably between 20 and 250 cm, the top layer is preferably between 1 and 20 mm thick.
  • the composite components can have different shapes; e.g. can be used as flat sheets, as corrugated sheets or as roof tiles be trained.
  • the plate-shaped components can in a simple way, e.g. divided by cutting discs or saws or cut to size for easy installation.
  • the polystyrene foam particles can be the usual additives included, e.g. Flame retardants or pigments, as well Cement mortar contains the usual aggregates to make up the composite building elements to impart the desired properties.
  • the components according to the invention can be in different variants are produced, which are within the scope of the invention Move procedure; all details can also be technically equivalent elements are replaced. During the practical Carrying out the procedure can use materials, shapes and sizes be changed as needed.

Claims (3)

  1. Elément de construction composites à base d'une couche de coeur en mousse particulaire de polystyrène et d'au moins une couche de couverture en mortier au ciment, caractérisé en ce que du mortier au ciment est déposé dans une couche intermédiaire dans le volume interstitiel des particules expansées de polystyrène, où les deux matériaux sont intriqués l'un dans l'autre, de sorte qu'un passage d'écoulement existe entre la couche de coeur et la couche de couverture, et une bonne liaison est crée entre la couche de coeur et la couche de couverture.
  2. Procédé de fabrication d'un élément de construction composite à base d'une couche de coeur en mousse particulaire de polystyrène et d'au moins une couche de couverture en mortier au ciment selon la revendication 1, caractérisé en ce que
    a) on introduit du mortier au ciment liquide et des particules expansées de polystyrène ayant un fort volume interstitiel dans un moule,
    b) on aspire l'air du moule et on introduit de la vapeur dans le moule, ce qui entraíne la pénétration à la surface du mortier au ciment dans les interstices des particules expansées de polystyrène, on expanse davantage les particules expansées et on les agglomère, puis on fait prendre le mortier au ciment pour former une couche intermédiaire, qui se solidifie en la couche de couverture et
    c) on refroidit l'élément de construction composite et on le retire du moule.
  3. Procédé selon la revendication 2, caractérisé en ce que la prise du mortier au ciment et l'agglomération des particules expansées de polystyrène ont lieu simultanément.
