Definitions

  • the present invention relates to the production of precast concrete beams intended for the manufacture of thermally insulated floors.
  • a classic technique for manufacturing floors consists of placing adjacent parallel beams, then interjoists between the beams, and pouring a compression slab on the whole beams-interjoists.
  • interjoists at least in part from insulating material to improve the thermal insulation at the level of the floor.
  • the interjoists are made for example of expanded polystyrene and do not participate in the mechanical strength of the floor.
  • the object of the present invention is to directly produce insulated prefabricated beams to complete the thermal insulation of floors, while making it possible to provide protection against fire without having to use fragile parts which can be easily broken. during transport and assembly on site.
  • This object is achieved by a process comprising the placement of the heel of the beam in at least one prefabricated element with a substantially U-shaped cross section and made of a thermal insulating foam material, the placement being carried out so as to carrying out the assembly with rigid connection of the beam and the prefabricated element, process according to which, according to the invention, the assembly is carried out by pouring the heel of the beam in the prefabricated element serving as formwork.
  • a beam heel can be cast in a row made up of elements placed end to end.
  • the prefabricated elements serve as lost formwork instead of U-shaped metal profiles usually used as formwork for casting the beam heels.
  • the prefabricated element is made of a material which preferably combines the properties of thermal insulation, fire resistance and mechanical resistance.
  • This material may be a phenolic foam or a mineral foam, and may optionally contain fillers to reduce its density and its cost, by example mineral fillers or organic fillers such as expanded polystyrene beads.
  • Figures 1 and 2 illustrate a beam 10 of reinforced concrete whose heel 11 is housed in several prefabricated elements 15 placed end to end.
  • Each element 15 has, in cross section, a U shape whose internal profile corresponds to the external dovetail profile of the cross section of the heel 11 of the beam.
  • Other forms of connection of the tenon and mortise type with rigid connection between the beam 10 and each element 15, in transverse direction, can be envisaged.
  • the elements 15 are prefabricated elements made of a thermal insulating material having good fire and mechanical resistance.
  • the elements 15 can in particular be made of a phenolic foam obtained by polymerization of a phenolic resin such as, for example, that described in French patent application No. 2,192,132.
  • Such a foam has the advantage of having a neutral pH or close to neutrality.
  • a non-acidic foam prevents the introduction of a corrosion factor of the reinforcements 12 of the beam.
  • inert mineral fillers are introduced into the phenolic resin before polymerization, which allows, with equal dimensions, to reduce the density and the cost of the product obtained.
  • the connection between the coating 16 and the element 15 is carried out during the prefabrication of the latter, the resin being poured onto a hard plasterboard roughened by notching to ensure better adhesion.
  • Elements 15, preferably identical and of standard lengths, are arranged in adjacent rows each comprising several elements placed end to end (FIG. 3). Reinforcements 12 are placed in the forms formed by the elements 15 and concrete is poured into these forms. Only the heels 11 of the beams 10 are cast. The prefabricated elements do not exceed the heels of the beams in height and leave free the support faces formed by the upper faces of the heels. The interjoists or slabs arranged between the beams can therefore bear directly on the concrete heels thereof.
  • the number of elements placed end to end in a row is determined according to the length of beam desired.
  • the elements 15 have their ends cut in tabs.
  • the invention also applies to prestressed concrete beams.
  • metallic wires or strands under tension can be placed in formwork formed by prefabricated elements, concrete being sunk next.
