Definitions

  • the present invention relates to the building sector, in particular construction elements and in particular the slabs and relates to a method of manufacturing self-formable and insulating slabs.
  • the invention also relates to a device for the implementation of this process as well as the slabs obtained.
  • reinforced concrete stiffeners requires a relatively long drying time for these stiffeners, which results in an intermediate storage of the slabs thus obtained relatively long and, as a corollary, requires large storage areas or halls.
  • DE-B-2 639 812 also discloses a manufacturing process and a machine for implementing this process, making it possible to obtain molded slabs based on polystyrene beads.
  • This process envisages, in fact, a molding of a polystyrene concrete constituted by a mixture of polystyrene beads and cement, the whole being compacted in a mold and a wire mesh being inserted in grooves provided for this purpose, during from the outlet of the molded product from the mold.
  • the present invention aims to overcome these drawbacks.
  • It relates, in fact, to a process for manufacturing self-forming and insulating slabs made of foamed synthetic material, in particular of expanded polystyrene, characterized in that it essentially consists of integrating, during the expansion molding of the synthetic material, at least one longitudinal section in the foam in formation and to completely cover it with said foam.
  • the invention also relates to a device for implementing this process, characterized in that it essentially consists of a continuous or discontinuous molding machine, the mold of which is provided at its rear end with at least a sealed opening for introducing at least one longitudinal profile, by means of introducing the profile or profiles into the mold and, optionally, by a device for continuously producing profiles.
  • the invention also relates to the slabs thus obtained which are characterized in that they are provided with at least one longitudinal section integrated in their mass.
  • the method of manufacturing self-forming and insulating slabs 1 made of foamed synthetic material, in particular of expanded polystyrene essentially consists to integrate, during molding, at least one longitudinal section 2 in the foam in formation and to completely cover it with said foam, so as to allow non-breakage.
  • the longitudinal section 2 is made of a thin folded metal sheet.
  • the longitudinal profile 2 can also be made, in accordance with an alternative embodiment of the invention, of a rigid extruded synthetic material such as PVC or the like.
  • the invention also relates to a device for implementing this process, shown particularly in Figures 2 and 3 and essentially consisting of a machine 3 for continuous or discontinuous molding, with which the mold 4 is provided at its rear end. at least one sealed opening 5 for introducing at least one longitudinal section 2, by means 6 for introducing the section or sections 2 into the mold 4 and, optionally, by a device 7 for continuously producing sections .
  • the means 6 for introducing the profile (s) 2 into the mold 4 is advantageously in the form of a movable carriage 8 slidably mounted, in a longitudinal direction, on the frame of the molding machine 3 by means of at least a displacement cylinder 9 and is provided, at its end opposite to said machine 3, with a crosspiece 10 for holding the profile or profiles 2.
  • This maintenance of the profiles 2 is provided either by one or more housings formed on the crosspiece 10 , either by clamps 11 open in the longitudinal direction and actuated by jacks 12.
  • the molded section is pushed out of the mold on the opposite side to the means 6, which simultaneously pushes the stiffening profile or profiles in the mold with a length corresponding to the new section to be molded.
  • These operations are repeated until the desired length of slabs is obtained, the profiles 2 having, in such a case, a length equal to that of the slabs to be obtained.
  • the device 7 for continuously producing profiles 2 can advantageously be in the form of either a continuous or discontinuous sheet bending machine or an injection molding machine.
  • the sheet bending machine can be fed continuously by a thin strip of sheet metal and carry out a continuous folding of this strip or even be fed by sections of sheet metal strips corresponding to a predetermined length of profiles 2.
  • the latter delivers at the outlet of its die a continuous profiled strip.
  • the device 7 can be provided at the outlet of the profiles 2 with a device 13 for cutting up said profiles 2 to the desired length.
  • the invention also relates to the slabs thus obtained which are characterized in that they are provided with at least one longitudinal section 2 integrated in their mass.
  • the longitudinal section (s) 2 integrated into the mass of the slabs 1 may have a very small thickness, which, in practice, is not compatible with a buckling behavior of said sections 2 along their vertical section, this behavior being provided by the material foam forming the mass of the slabs 1, namely, generally polystyrene.
  • the invention therefore allows the production of reinforced polystyrene slabs having a very low unit weight and which can easily be transported and handled by a single person.
  • the profiles 2 are integrated into the mass of the slabs 1, the latter have a finish on their perfect underside, this finish possibly being improved by providing moldings, so that subsequent coating of this face becomes useless.
  • the process according to the invention allows for production of slabs according to demand, that is to say according to the just-in-time working method, so that stocks after manufacture can be reduced to a minimum, which leads to a gain in productivity and a reduction in the cost price.
