Definitions

  • the invention relates to a method for treating thermal bridges between a floor and a wall adjacent to the floor.
  • the invention relates more particularly, although not exclusively, to a method for treating thermal bridges between a floor and a wall adjacent to one of the non-load-bearing edges of said floor (as opposed to the load-bearing edges of the floor which take up the majority of the forces applied to the floor). floor).
  • thermal bridges that is to say that of the path of conduction of heat or cold through the continuity of a heat-conducting material from the exterior of the building to the interior. This is particularly the case for floors which form thermal bridges due to their contact with the exterior walls of the building.
  • thermally insulating bodies between the wall and the floor, each body comprising reinforcements crossing the body so as to protrude on either side.
  • the reinforcements protruding towards the interior of the building are located coated so that they are rigidly attached to the floor.
  • the reinforcements protruding from the other side of the thermally insulating body are then in turn embedded in an external concrete element continuing the construction of the wall.
  • the floor and the wall are rigidly linked and the thermally insulating bodies arranged between them limit the corresponding thermal bridges.
  • thermally insulating bodies are for example described in the patent EP 0 866 185 .
  • the aim of the invention is to propose a method for treating thermal bridges between a floor and a wall adjacent to the floor which can be implemented easily.
  • the second reinforcements are embedded in the compression slab so that they are rigidly attached to the floor.
  • the first reinforcements are also embedded in an external concrete element continuing the construction of the wall. In this way, the floor and the wall are rigidly linked and the thermal insulation elements arranged between them limit the corresponding thermal bridges.
  • the invention thus makes it possible to alternate the rigid connection zones between the floor and the wall with the thermal insulation zones.
  • the reinforcements are therefore concentrated between the thermal insulation elements, at the level of the structural connection elements, so that the thermal insulation elements do not need to fulfill the function of anchoring the floor to the wall.
  • the various insulation elements are free of reinforcement, which simplifies their handling and handling.
  • the thermal insulation elements and the structural connection elements each need to perform only one function, they are small in size, which facilitates even more their handling and handling.
  • the method according to the invention therefore proves to be simple and quick to implement.
  • a thermal insulation element is proposed for the implementation of the process for treating thermal bridges which has just been described and in which a lower portion of the block made of thermally insulating material comprises a tab which forms a longitudinal extension of said portion lower and which is intended to receive the structural connecting element.
  • the structural connection element can simply be placed on the bracket which facilitates its installation along the portion of the wall. This further promotes the implementation of the method of the invention.
  • the tab ensures better treatment of thermal bridges by being arranged between the wall and the floor at the level of a rigid connection zone between the floor and the wall.
  • Such a tab ensures continuity of the thermal insulation in the lower part of the floor between two thermal insulation elements separated by the structural connection element resting on said tab.
  • a structural connection element is also proposed for the implementation of the thermal bridge treatment process which has just been described and in which the concrete of the block of the structural connection element is a concrete with lower thermal conductivity at 1 watt per meter-kelvin.
  • connection element also actively participates in reducing thermal bridges between the wall and the floor while fulfilling its function of anchoring the floor to the wall.
  • a structural connection element is also proposed for implementing the thermal bridge treatment process which has just been described and in which the concrete of the block of the structural connection element is a very high performance concrete.
  • a pre-slab intended to support the concrete of a compression slab is proposed to jointly constitute with this compression slab a floor, the pre-slab comprising a concrete body and at least one thermal insulation element as previously mentioned secured to an edge of said preslab.
  • the method according to a first implementation of the invention aims here to treat thermal bridges between a floor 1 and a wall 2 adjacent to one of the non-load-bearing edges of said floor.
  • the process is implemented during the construction of the building.
  • the wall 2 is mounted up to approximately the level where the floor 1 is intended to be laid.
  • the upper part of the mounted wall portion 3 has a stop 4 which allows a better connection with the rest of the wall 2 to be built as we will see later.
  • Beams P, supported by one or more props, are then positioned against the mounted portion 3 of the wall 2 so as to extend normal to said mounted portion 3 in order to serve as support for the construction of the floor 1.
  • pre-slabs (only one of which is referenced 5 here) are successively joined to each other on the beams P to delimit the surface of the floor 1.
  • One of the longitudinal edges 8 of at least one of the pre-slabs 5, forming partly one of the non-load-bearing edges of the floor 1, here runs along the portion 3 of the wall 2 considered.
  • Figure 3 thus illustrates the already mounted portion 3 of the wall 2 and said pre-slab 5.
  • the pre-slab 5 is mounted so that its longitudinal edge 8 extends along the mounted portion 3 of the wall 2 but with an offset relative to said portion 3 A space is therefore left between portion 3 and pre-slab 5.
  • thermal insulation elements 6 and connecting elements are then arranged along said longitudinal edge 8 of said pre-slab 5.

Said thermal insulation elements 6 and structural connection 7 form thus a border between the preslab 5 and the corresponding portion 3 of wall 2.
  • the different thermal insulation elements 6 and the different structural connection elements 7 are all elements independent of each other which facilitates their handling in particular to arrange them between the longitudinal edge 8 of the preslab 5 and the portion 2 of wall 3 already built.
  • All the structural connection elements 7 are here identical to each other and all the thermal insulation elements 6 are here identical to each other. In this way, the different thermal elements 6 and structural connection 7 together define a border between the pre-slab 5 and the wall 2, a continuous border of the same height along the entire length of the longitudinal edge 8 of the pre-slab 5 and therefore along the entire length of the corresponding wall.

  • the rectilinear border 10 therefore proves not only flexible and supple but also light. This facilitates the handling of the border 10 and makes it easier to secure it to the concrete body of the pre-slab 5. In addition, it proves possible to easily cut the rectilinear border 10 to modify its length according to production needs. This once again facilitates the fixing of the rectilinear border 10 to the preslab 5.
