Definitions

  • the present invention relates to a precast slab with thermal break made of a curable molding material, in particular concrete, for the manufacture of a floor obtained by the juxtaposition of several prefabricated slabs, said prefabricated slab having rectilinear lateral and longitudinal edges for the juxtaposition of several prefabricated slabs and delimiting the circumference of the prefabricated slab.
  • the present invention also relates to a method of manufacturing a prefabricated slab with a thermal break comprising a casting step in a mold of a curable molding material, for example concrete.
  • the present invention relates to a method of constructing a floor made of a hardenable molding material, for example concrete, cast on a formwork formed by the juxtaposition of several prefabricated slabs with a thermal break, said method comprising a step of laying at least one prefabricated slab and a step of casting a layer of molding material.
  • a hardenable molding material for example concrete
  • the invention relates to the technical field of building construction, and more specifically the construction of buildings from prefabricated elements in the factory, such as slabs intended to be conveyed to the place of construction, in particular with a view to reducing the duration of the construction. construction site.
  • a prefabricated slab is formed by pre-casting in the factory a layer of a curable hydraulic mixture, for example concrete, in a mold, also called formwork table.
  • a curable hydraulic mixture for example concrete
  • a mold also called formwork table.
  • prefabricated slabs are then juxtaposed and resting on bearing elements such as walls, beams, etc. They then make it possible both to form a formwork for the casting in place of a complementary compression slab, and also constitute the lower part of the floor.
  • Thermal breakers are conventionally used, for example in the form of polystyrene blocks which are inserted and inserted between the ends of the floor and the walls in order to achieve the isolation of the floor-wall junction to avoid the formation of a thermal bridge. .
  • the publication is known FR 2 873 727 A1 a method for limiting thermal bridges by adding blocks of insulating material during the construction of a wall and a slab.
  • Publication is also known EP 1 355 013 A1 a similar method of assembling a wall and a slab comprising between the chaining of the wall and the slab a plurality of thermal insulation blocks distributed discontinuously to improve the thermal insulation. It is well known that this floor-wall junction generates significant energy losses which must be treated to comply with the standards in force.
  • Thermal breakers having additional properties of fire resistance such as those described in the publication, are also known.
  • FR 2 854 417 A1 Such thermal breakers are also reported to be inserted between the ends of the floor and the wall. This configuration nevertheless has disadvantages, because it requires on site a step of additional and tedious installation. This expensive solution is not more satisfactory from the point of view of implementation, because it is difficult to ensure the good position in position of the thermal switches in the casting phase of the floor.
  • the publication FR 2 854 417 A1 discloses a prefabricated slab with thermal break according to the preamble of claim 1.
  • thermal breakers are attached to the prefabricated slab at the place of construction and are positioned by holding elements integrated into the slab. Then, one comes pouring a layer for example of concrete which then seals the thermal breakers in the floor.
  • This solution makes it possible to isolate more simply the floor-wall junction while maintaining a good mechanical resistance.
  • this solution is not completely satisfactory because there is a thermal bridge. In fact, the thermal flow passes through the thickness of the prefabricated slab or pre-slabs, and reaches the wall. In this case, the thermal breakers do not cut the thickness of the prefabricated slab, but only the thickness of the compression slab cast in place. This solution therefore guarantees only a partial break of the thermal bridge.
  • the publication GB 2,355,024 A discloses an insulating building panel that can be used as a wall or slab and having a layer of polystyrene covered with a layer of concrete.
  • the polystyrene layer has longitudinal slots and forms a mold for the concrete layer.
  • Such insulating construction panels do not guarantee the rupture of the thermal bridge over the entire thickness of the slab.
  • these require a large amount of insulating material since the insulating layer forms a single block covering the entire surface of the slab.
  • the publication EP 1 350 898 A1 discloses cellular building boards formed of a first concrete layer whose surface has a peak and hollow shape. The hollows are filled with polystyrene blocks and a second layer of concrete similar in shape to the first layer of concrete is deposited on this assembly. In this embodiment also the insulating blocks which are arranged on the entire surface of the slab use a large amount of material. In addition, such a slab must be cast on site and thermal bridges remain in the thickness of the concrete layers.
  • the present invention aims to overcome these disadvantages by providing a prefabricated slab or pre-slab to ensure the rupture of the thermal bridge at the floor-wall junction and without degrading the fire resistance characteristics of the floor obtained.
  • the invention achieves such a goal by a design and implementation simple and inexpensive respecting current standards including in terms of mechanical properties, thermal and fire resistance if necessary.
  • the invention relates to a prefabricated slab as defined in the preamble of claim 1, characterized in that it comprises a plurality of first blocks of separated material independent of each other only located on the periphery of said prefabricated slab, said plurality of first blocks of material is disposed along at least one of said rectilinear lateral or longitudinal edges of said prefabricated slab and at a distance from said lateral or longitudinal edges on at least a portion of the periphery of said prefabricated slab, in that the material of said first blocks has specific properties different from those of said molding material, and in that said first blocks are integrated at least in part in the thickness of said prefabricated slab.
  • the invention advantageously makes it possible to achieve a strong reduction of the thermal bridge and, where appropriate, a fire resistance over the entire thickness of the prefabricated slab.
  • said prefabricated slab comprises at least one holding element for holding said first blocks in position.
  • said first blocks are integrally integrated in the thickness of said prefabricated slab.
  • said blocks are arranged discontinuously and are aligned substantially parallel to said edge so as to provide at least one gap for the passage of reinforcement between them.
  • the prefabricated tile comprises a plurality of second blocks of material superimposed on said first blocks of material and in that the material of said second blocks may have specific properties different from those of said molding material.
  • Said first and second blocks may be coupled at least in part to a holding element arranged to allow their superposition.
  • each holding element is superimposed on said first block and contains at least in part said second block, or said holding member embraces at least partially said first block and said second superimposed block.
  • said first and second blocks are substantially parallelepipedic.
  • Said first and / or second blocks advantageously comprise materials having thermal insulation properties and / or fire resistance properties.
  • said materials of said first blocks and / or said second blocks are selected from the group consisting of polystyrene, polyurethane, vacuum panels, rock wool, sheep wool, glass wool, concrete lightweight, wood, wood concrete, cellular concrete, silico-limestone, plaster, concrete expanded glass, perlite, pumice, porous stone, cellular glass, thermoplastic foam or a combination of these materials.
  • the invention also relates to a method for manufacturing a prefabricated slab as defined in the preamble of claim 12, characterized in that it comprises a step of fixing a plurality of first blocks on the bottom of said mold along at least one of said rectilinear lateral or longitudinal edges of said mold.
  • the invention also relates to a method of constructing a floor as defined in the preamble, of claim 14 characterized in that a plurality of second blocks is superimposed on said first blocks integrated in said prefabricated slab.
  • each second block is superimposed on a first block of said prefabricated slab by means of at least one holding element.

  • the Figure 1A shows a first step of construction of the prefabricated slab 1 which incorporates at least in part in its thickness a first block 3 of material near the edge 11 of the prefabricated slab 1.
  • This first block 3 is of smaller dimensions than those of the slab prefabricated 1 and is made of a thermally insulating material and / or fire resistant as needed.

  • This second block 4 is intended to provide thermal insulation and / or fire resistance over the entire thickness of the layer 8 of the floor 2 which will be poured on the site.
  • the combination of the first 3 and second 4 blocks thus provides these thermal insulation properties and / or fire resistance on the total thickness E of the floor-wall junction.
  • This configuration advantageously makes it possible to greatly reduce the thermal bridge located at the floor-wall junction.
  • the first and / or second blocks 3, 4 are located only on the periphery 12 of the prefabricated slab 1 and are not distributed over the entire surface of the prefabricated slab 1 as in certain embodiments of the state of the art. art, which allows to significantly limit the amount of insulating material and reduce manufacturing costs, while providing a thermal result more than optimal.

In the configuration illustrated in figure 2 it is observed that the length L of the blocks 3, 4 is parallel to the edge 11 of the prefabricated slab 1. In addition, the blocks 3, 4 are aligned on the following ones and are spaced apart by a given interval 5, making it possible to pass These reinforcements 6 provide the mechanical strength at the floor-wall junction. They are usually made of steel or the like. As shown for example in figures 3 and 5 , the blocks 3, 4 are arranged along a lateral edge 11 and a longitudinal edge 11 and at a distance d from said edges 11. Of course, the four edges 11 may comprise blocks 3, 4. In addition, the thickness e of the blocks 3, 4 is included in the periphery 12 of the prefabricated slab 1 delimited by the edges 11. This configuration makes it possible to avoid report separate insulating blocks at the ends of the prefabricated slab complicating the implementation on site.
