Definitions

  • the present invention relates to beams intended for the manufacture of an insulating floor and comprising a metallic lattice reinforcement and a heel in which the lower part of the reinforcement is embedded.
  • the object of the invention is to provide beams also making it possible to directly produce floors with an insulating underside, while simplifying the manufacture and handling of the beams as much as possible.
  • thermal insulation is easy to perform and control since it depends essentially on the thickness and density of the light insulating concrete used.
  • the weight of the beams is considerably reduced - a division of the weight by two, even by three, is possible -, which greatly facilitates handling on site.
  • the light insulating concrete provides protection of the reinforcement against the corrosion and makes the beam benefit from its good fire resistance.
  • shoring is possible directly under the beam, which is more delicate when an insulator is attached on the underside, and the underside of the heel can be plastered directly, which is not the case with the most insulators.
  • Light insulating concrete is, as known per se, produced with a mixture comprising a hydraulic binder (cement), particles of expanded polymer (for example polystyrene beads) and water.
  • a hydraulic binder cement
  • particles of expanded polymer for example polystyrene beads
  • the beams 10 according to the invention are of the lattice type with a metal frame 11, for example triangulated, the lower part of which is embedded in a heel 12 of light insulating concrete.
  • the beams are prefabricated in the factory in the same way as the usual truss type beams provided with a conventional concrete heel, the conventional concrete being replaced by a light insulating concrete whose thickness e may be greater.
  • the mechanical resistance of the beam only the tensed steel section of the reinforcement is involved in the calculation, the light insulating concrete not being taken into account.
  • the intervals between beams are filled with insulating interjoists 15, for example also made of light insulating concrete ( Figure 1).
  • insulating interjoists 15 for example also made of light insulating concrete ( Figure 1).
  • a so-called compression slab is poured onto the beams 10 and interjoists 15, to take up the compression forces, while the tensile forces are taken up by the reinforcements of the beams. This gives an insulated floor directly on the underside.
  • the light insulating concrete of the heel 12 is based on expanded polystyrene balls mixed with a hydraulic binder and water. It is thus possible to produce a light insulating concrete whose density can drop to 2 kg / m3.
  • a beam according to the invention was produced in the following manner.
  • Two end pieces 13, 14, for example heel sections made of common aggregate concrete, are positioned between two metal sections forming the lateral cheeks of the formwork in which the light insulating concrete is to be poured.
  • the parts 13, 14 form the end walls of the formwork.
  • the light insulating concrete used is of liquid consistency based on expanded polystyrene beads with a density of 3 kg / m3.
  • a conventional truss type reinforcement is positioned after pouring the light insulating concrete.
  • the end pieces 13, 14 have grooves formed in their upper face to receive the lower sections of the metal frame. Thus, these end pieces have three functions: lost formwork allowing the dimensioning in length of the beam, reinforcing shims and transmission of the compression forces during the use of the beam.
  • Tests carried out on a single beam or on a floor demonstrate a mode of behavior identical to conventional beams with slightly greater flexibility for an equivalent steel section.
