Definitions

  • the present invention relates to a floor used for the construction of building comprising at least one U-shaped metal profile having two webs, longitudinal folds located on either side of a beach, a means of insulation thermal contained in the space between the webs of the profile, and a compression slab in reinforced concrete.
  • the forms are provided with small ribs on which are placed plates or blocks of rigid polyurethane foam or material similar.
  • a welded mesh is placed on the wings of the formwork, before the concrete is poured.
  • the profile is perforated.
  • This structure makes it possible to reduce the thickness of the compression slab while increasing the total inertia of the mixed steel / concrete slab. In addition, it provides thermal insulation in many cases.
  • the floor does not meet the optimum conditions in terms of thermal insulation, sound insulation and mass-to-charge ratio.
  • the object of the invention is to present an improvement of prior art cited in the simplification of construction as well as in the field of technical performance such as, in particular, the resistance to load compared to the floor mass, sound insulation, thermal insulation.
  • the floor favors also a construction on site as well as a prefabricated industrialization.
  • the invention relates to a floor used for building construction comprising at least one U-shaped metal profile having two cores, folds longitudinal 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 reinforced, characterized in that it is arranged between the reinforced concrete slab and the medium thermal insulation, an air space providing additional thermal insulation and phonic.
  • the floor 1 used for building construction is composed as shown in Figure 1, of metal profiles 2 in the form of U having a track 3 and two cores 4, 5, which can be of different shapes, these webs 4, 5 being produced by longitudinal folding of a sheet blank.
  • the profiles are juxtaposed with each other to form a formwork by nesting a core 4 of 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 formwork plan and to be able to close the joint between the profiles when passing the liquid concrete at the time of pouring.
  • welded mesh 9 for reinforcing reinforced concrete.
  • the frames in the form of welded mesh 9 are always linked to their base, of the formwork type, slabs, to prevent them from rising to the surface of poured concrete, by the effect of Archimedes' push.
  • the welded mesh is placed in abutment on the flat surfaces of the folds 6,7 then linked to a part of the folds by means chosen from, a weld, for example by point, the flat part ensuring good mechanical and electrical contact for this type of connection; attachment by localized cutting of the fold of the core, cutout forming a tongue 10, 11 raised then folded over a round of the trellis welded ; an independent metal link such as a clip now by pinch the mesh welded to the frame or a metal wire.
  • the floor comprises insulation means 12, 13, contained in the space between the cores 4,5 of the profiles 2 and between the area 3 of the profile and the slab of concrete 14 reinforced with the welded mesh 9.
  • the insulation means 12, 13 include a on the one hand, a solid material 12, placed on the track 3 and on the other hand, an air space 13 located between the solid insulation 12 and the slab 14 ensuring sound insulation associated with a additional thermal insulation.
  • An air gap 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 at all envisaged in the construction of floors the fact that the floor formwork and a container usually filled with material liquid that is concrete when used.
  • Air flow without circulation means a closed air space that does not allow not a movement and or a renewal of the air. A movement and or a air renewal in this space would no longer ensure the function thermal and / or sound insulation of the floor.
  • the core 15 can be solid and removable, displaceable longitudinally to the profiles after solidification of the concrete, in particular in the hypothesis of a prefabricated floor realization.
  • the core 15 can be an air cushion may be cellular or an envelope containing a drainable fluid. The cushion or envelope may remain enclosed 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 profiles 2, to allow the concrete cast to coat a part 17, 18 of the cores of the sections 4, 5, and to produce a reinforced beam associated with the reinforced concrete slab.
  • the nucleus can remain permanently, and can be made of a honeycombed or non-honeycombed box, of any material such as metal, polystyrene, gummed or tarred cardboard.
  • the air space 13, in another example of application, as shown in the Figure 3, can be achieved by the use of a panel 20, slightly arched supporting the mass of concrete still liquid.
  • the panel 20 in the vault is for example, a sheet preformed braced in support, either on the webs 4,5 of the profiles 2, or on the medium rigid insulation 12.
  • the panel can be of any material, like the core 15.
