Definitions

  • the present invention relates to a floor used for the construction of building comprising at least one U-shaped metal section with two souls, longitudinal folds located on either side of a beach, a means of isolation thermal content in the space between the souls of the profile, a compression slab reinforced concrete and an air space, according to the preamble of claim 1.
  • the forms are provided with small ribs on which are placed plates or blocks of rigid foam of polyurethane or a material similar.
  • a welded mesh is placed on the flanges of the formwork, before pouring the concrete.
  • the profile is perforated.
  • This structure makes it possible to reduce the thickness of the compression slab while increasing the total inertia of the steel / concrete composite slab. In addition, it ensures thermal insulation in many cases.
  • the floor does not fulfill the optimum conditions in terms of thermal insulation, sound insulation and mass-to-load ratio.
  • the object of the invention is to present an improvement of prior art cited in the field of simplification of construction as well as in the field of technical performance, such as, in particular, the dependence on the floor mass, sound insulation, thermal insulation.
  • the floor promotes also on-site construction as well as prefabricated industrialization.
  • FR-A-1 555 470 has a floor according to the preamble of claim 1.
  • the subject of the invention is a floor used for building construction having at least one U-shaped metal profile with two cores, folds longitudinals located on either side of a beach, a means of thermal insulation contained in the space between the webs of the profile, and a concrete compression slab armed in which floor is spared, between the reinforced concrete slab and the medium thermal insulation, an air space providing additional thermal insulation and in which floor the souls comprise folds for their interlocking, as defined in the characterizing part of claim 1.
  • the floor 1 used for building construction is compound as shown in Figure 1, U-shaped metal sections 2 having a beach 3 and two souls 4, 5, which can be of different shapes, these webs 4, 5 being made by longitudinal folds of a sheet blank.
  • the profiles are juxtaposed with each other to form a formwork by the interlocking of a soul 4 a profile with the core 5 of the concomitant profile.
  • Each of the two souls of each profiles respectively comprises folds 6, 7, 8 for interlocking.
  • the interlocking has in particular the advantages of being able to align the profiles in the plan of the formwork and to be able to close the join between the profiles at the passage of the liquid concrete at the moment of casting.
  • welded mesh reinforcement 9 reinforced concrete.
  • the frames in the form of welded mesh 9 are always connected to their base, of the formwork type, hourdis, to prevent them from rising to the surface of liquid poured concrete, by the effect of the buoyancy of Archimedes.
  • the welded mesh is placed in abutment on the flat surfaces of the folds 6,7 and then bound to a portion of the folds by means selected from, a weld, for example by point, the flat part ensuring a good mechanical and electrical contact for this type of connection; a hanging by a localized cut of the fold of the soul, cutting forming a tongue 10, 11 raised and folded on a round of the lattice welded ; an independent metal link like for example a clip now by pinching the mesh welded to the frame or a wire.
  • the floor comprises insulation means 12, 13, contained in the space between the webs 4,5 of the profiles 2 and between the range 3 of the profile and the slab of the reinforced concrete 14 of the welded mesh 9.
  • the insulation means 12, 13 comprise a part, a solid material 12, placed on the beach 3 and, on the other hand, an air space 13 situated between the solid insulation 12 and the slab 14 providing sound insulation associated with a additional thermal insulation.
  • An air space preferably greater than 3 cm, without circulation, is recognized as one of the best thermal insulators. If this means is known in the case of vertical insulating walls, it is not envisaged in the construction of floor the fact that the floor formwork and a container usually filled with the material liquid that is concrete during its use.
  • Circulationless air space means a closed air space that does not allow not a movement and or a renewal of the air. A movement and or a renewal of air in this space would no longer ensure the function of thermal insulation and or sound of the floor.
  • the use is provided a core 15, as shown in Figure 2, supporting the mass of concrete still liquid, before solidification.
  • the core 15 can be solid and removable, movable longitudinally to the profiles after solidification of the concrete, in particular in the hypothesis a prefabricated floor construction.
  • the core 15 may be an air cushion can be alveolar or an envelope containing a fluid that can be drained. The cushion or envelope can remain locked in the floor structure.
  • the form of the core formed in the space between the solid insulation 12 and the slab 14 allows a clearance 16 at the juxtaposition of the sections 2, to allow the concrete cast to encase a portion 17, 18 of the webs of the sections 4, 5, and to realize a military truss associated with the reinforced concrete slab.
  • the nucleus can remain permanently, and can be constituted by a cellular box or not alveolie, of any matter such that metal, polystyrene, cardboard gummed or tarred.
  • the air space 13, in another application example, as shown in FIG. 3, can be achieved by the use of a panel 20, slightly vaulted supporting the mass of concrete still liquid.
  • the panel 20 vault is for example, a sheet preformed abutting abutment, either on the souls 4,5 of the profiles 2, or on the medium rigid insulation 12.
  • the panel can be of any material, such as the core 15.
