Each of these floor modules is rectangular and its two sides extending parallel to the bearing axis (A) of the floor 2 can respectively define a nesting shoulder 17a and an interlocking shoulder 17b, as illustrated in FIG. figure 2b .
  • An interlocking shoulder 17a of a floor module is designed to cooperate with an interlocking shoulder 17b of a floor module adjacent thereto.

  • Each of the points constituting an interface between the partial floor slab 4 and one of the first end portions 5 is ideally located at the zero bending moment of the floor 2. That is, the normal stresses are balanced in the mechanical system so that they are zero in each of these points, only the shear force having an effect. The influence of the concreting stop is thus greatly reduced.
  • the bottom of the formwork 6 is notably positioned between the joists 3. It is typically composed of several wooden or concrete panels resting on the slats 22, said slats 22 being fixed on each side of the joists 3.
  • the formwork can be held directly by the joists 3. It can, for example, be inserted in grooves or on shoulders typically formed on each side of the joists 3.
  • This formwork base 6 may, however, be made in any other suitable form, for example in the form of thin precast concrete slabs constituting an extension of the partial slab of floor 4.
  • This formwork base 6 is advantageously made on a slope, thus allowing concreting with a variable inertia approaching the ends of said two first end portions 5.
  • the bottom of formwork is made of slope and will allow the realization of a layer of thicker concrete along the supporting wall 1 that along the partial floor slab 4.
  • the form base 6 may be temporarily positioned, that is to say it may be positioned to allow pouring concrete and then removed.
  • the slats 22 can be removed to allow the removal of the panels constituting the bottom formwork 6.
  • the removal of the formwork bottom is mainly of aesthetic interest.
  • the partial floor slab 4 is armed in the lower part to take the tensile forces due to bending.
  • CVSE Heating Ventilation Sanitaire Electricity

  • the concrete of the partial floor slab 4 fills the expanded "D" diameter machining located in the areas in which the floor comprises the partial floor slab 4.
  • the widened "D" diameter machining is intended to be filled with concrete during subsequent pouring of concrete. In both cases, this makes it possible to obtain a composite action between the joists 3 and the concrete.

These reinforcements 12 are located in the lower part of the partial slab 4 and are engaged in said partial slab 4. They traverse the partial slab 4 along its entire length and extend in part in each of said two first end portions 5 , above the formwork base 6.

  • Attaching the connecting elements 9 on the uprights 7 of the wall 1 has many advantages. Indeed, if we fix the junction elements 9 directly on the wall tile 8, we should be careful to use a wall slab 8 sufficiently strong and thick to withstand the tensile force exerted by the floor 2 on she. By fixing the joining elements 9 on the uprights 7 of the wall 1 and by avoiding, through the openings 11, exerting a tensile force on the wall slab 8, it is possible to use walls 1 comprising Wall slabs 8 much thinner. This limits the amount of concrete needed in buildings and therefore the volume of walls which represents an ecological advantage and a gain of living space in buildings.

  • the method for manufacturing a wood-concrete composite structure according to the second embodiment of the invention differs from the method of manufacturing a wood-concrete composite structure according to the first embodiment of the invention only in that, in the fourth step of pouring concrete into said end portions 5, 5 'of the floor 2, the concrete is poured so as to embed in the concrete all the parts of the connecting elements 9, 9', the wooden plate 3a and recesses 27 that it comprises, longitudinal reinforcements 12, first 15a and second 15b transverse reinforcements, cap frames 13 and chaining reinforcements 19 located in these parts 5, 5 ', for seal the load-bearing walls 1 and bracing 1 'to the floor 2.
  • the wood-concrete composite structures according to the first or second embodiment of the invention comprise only a load-bearing wall 1, do not comprise a bracing wall 1 'and have a floor 2 comprising only a first end portion 5.
  • Such structures can typically be used for the realization of a balcony.
  • the wood-concrete composite structures according to the first or the second embodiment of the invention comprise only two supporting walls 1 and do not include a bracing wall 1 '.
  • Such structures can typically be used for the realization of a gateway.
  • the wood-concrete composite structure according to the invention makes it possible to produce comfortable, solid and ecological constructions whose acoustic and thermal performances are much better than those of all-wood constructions.
  • the acoustic insulation is improved compared to a structure all wood thanks to the presence of concrete.
  • the walls bring thermal inertia to the building thanks to their concrete located on the inner side with respect to the thermal insulators (the thermal insulators can indeed be inserted between the uprights 7, 7 'of the walls).
  • the method of manufacturing a wood-concrete composite structure according to the invention makes it possible to minimize the quantity of tasks to be performed on site.
  • the process of producing a building using a wood-concrete composite structure according to the invention is, for a substantial part, carried out in a workshop. It is then possible to master several physical parameters and to precisely organize the tasks. Weather hazards do not influence the quality of products or the working conditions of employees. Specific equipment is made available facilitating and accelerating the realization.
  • the CVSE networks are positioned in the floor. These flows are the only technical interaction between the structure and the building. The congestion and disorder caused by the installation of these networks are sources of danger in an environment such as that of a construction site. The integration of these sheaths Floor slab techniques contribute to the cleanliness of the work areas. The safety of the workers on site is thereby increased.
  • the quality and the temperature of the air in the workshop allow a good management of the quality of the floor. Concrete is exposed to ideal conditions so that its chemical reactions are optimal. When laying the elements have a partial mechanical strength. The temporary structure formed by the prefabricated elements still unbound is already forming storage and circulation platforms.
  • the speed of installation on site is an asset to the nuisance of building a building in an environment. Noise, dust, vehicle roundtrips and construction time are reduced. The impact on the neighborhood is minimized.
