Definitions

  • the construction of a construction without basement, and in particular of individual houses without basement, is generally carried out on perimeter walls founded on good soil, or at least at the regulatory depth frost-free, with pouring between these walls a non-load-bearing concrete slab.
  • a more advantageous solution in terms of insulation, both in cold and in humidity, consists in creating a crawl space, that is to say in making a carrier slab independent of the ground and resting on the perimeter walls. This solution is of course more expensive than the previous one, since it requires mounting perimeter walls of greater height.
  • Document FR-A-2 505 906 discloses a process for producing a heat-insulating floor of the type comprising a concrete slab on the median. According to this process, large insulating plastic plates forming the segments are placed on the ground at regular intervals, the segments are covered with a plastic film which follows their contours and extends over the ground in the intervals between the segments, and is poured. the reinforced concrete slab on the segments and between them on the insulating film.
  • the invention for the realization of a rigid foundation slab allowing to carry a costruction consists in carrying out specific foundations established at least on the periphery of the slab to be produced, in proceeding with the preparation of a planar soil and leveled at the level of said point foundations, to place on the ground thus prepared formwork cheeks recoverable in the periphery of the slab to be produced, to have in the center of the rows of lost formwork elements leaving spaces intended to form the ribs of the slab with possibly connecting members of said formwork elements lost between them, to be arranged between the rows of formwork elements for sealing, insulation and spacing of the bottoms of beams and ribs with profiled U, these said elements defining the width of the beams and comprising insulation on the underside, to carry out the reinforcement of the periphery and rib beams, to arrange a tr reinforcement mesh of the slab on the upper face of the lost formwork elements, then pour concrete on the assembly thus produced.
  • the process makes it possible to reserve, in the core of the beams and periphery beams, regular crossings for the ventilation of the underside of the slab, or possibly for the passage of pipes which would have been forgotten before pouring.
  • the point foundations are constituted by wells concreted to the regulatory depth or on the resistant layers of the ground, or by micro-piles and it is understood that, provided that they were provided at a sufficient level, the process according to The invention enables a basement to be made later, without reworking the building under construction and therefore very inexpensively, should it one day be desirable.
  • the apparatus for implementing the method, for which protection according to the EPC is not sought comprises lost formwork elements made of a light and resistant material.
  • lost formwork elements may for example be constituted by blocks of foam made of expanded plastic, or cardboard boxes reinforced by a cellular network.
  • Cardboard boxes have the advantage of being able to be delivered flat and to be set up on site, without the need for special tools, with reinforcing braces.
  • the lost formwork elements have the ability to nest end to end by means of special elements, called connecting elements, so as to achieve a rib continuity. These special elements can form a formwork for a transverse intermediate beam reinforcing the rigidity of the slab.
  • the formwork elements could be square so as to constitute a “honeycomb” slab if the conditions of use or load required it.
  • connection elements may include reservations serving as crossings perpendicular to the ribs.
  • the rigidity of the slab is obtained by the height of the ribs, achieved economically thanks to the low cost of lost formwork.
  • the lost formwork elements can receive devices ensuring the spacing of the reinforcing mesh from the slab.
  • these spacers can be adapted to one or more layers of trellis.
  • the ribs in the case of uneven or rocky soils, can be leveled at the highest point.
  • the point foundations themselves being leveled off at this level the external perimeter formwork is then produced in two parts, the first being leveled off at the bottom of the slab and the foundations, to thus define an irregular volume that the we can temporarily fill with sand or with a pulverulent material, support of the slab bottom and lost formwork, and a second part formed by extensions of the thickness of the ribs increased by that of the compression slab, allowing the pouring of the slab. After drying and stripping, the sand is removed naturally.
  • the slab and the support structure in a single pour.
  • a foundation slab with beams support of a height greater than that of the slab is carried out in the ground, after leveling the ground and before placing the formwork elements of the slab, excavations for the housing of the support beams of the slab, we place in each excavation a formwork element lost in cardboard, we backfill between the excavation and the lost formwork and we fold on the ground the part of the lost formwork exceeding the buried level of the beam, so that after placement of the external formwork elements and internal constituent elements of the slab the slab and the beams are poured in a single operation.
  • the formwork can be made with any rigid and light surface such as cardboard, wood fiber, plastic or other.
  • the choice of formwork material must be made according to the nature of the soil. The more the soil can be cut cleanly at a level very close to the beam or sill to be formed (and the less then there is backfill), the lighter the formwork can be. On the other hand, the more powdery the soil, the wider the excavation and the backfill, and the more rigid the material and the greater the number of shims or spacers.
  • the formwork can receive a seal internally which will prevent possible infiltration by under pressure, thus allowing the realization of a sealed casing.
  • FIG. 1 there is shown in 1 concrete wells constituting foundations sinking to the resistant layers of the soil. Although only two wells 1 are visible in the figure, it will be understood that there is a well at each corner of the slab to be made. Between the wells 1, the ground 2 is leveled and leveled at the level of the point foundations formed by the wells 1.
  • the lost formwork elements are constituted by cardboard boxes which can be delivered flat and placed in volume on the site, with reinforcing braces, without the need for any particular tool.
  • connecting elements 6 could include reservations serving as crossings perpendicular to the ribs.
  • spacer elements 7 which define the width of the beams.
  • the spacing elements 7 are made of baryta cardboard, serving as a seal against capillary increases through the ribs, and have a U-shaped profile.
  • the elements 7 have an insulator 8, for example polystyrene, on the underside and may have spacers (not shown in the drawing) for the reinforcement of the beams.
  • Crossing reservations 9 are provided in the spacer elements 7.
  • spacer members 10 constituted by pieces of cardboard serving to separate the formwork 5 from the mesh 11 of reinforcement of the slab 3.
  • concrete is poured, which is preferably done at the pump. After drying, only the formwork cheeks 4 are recoverable.
  • FIG. 2 to 4 there is shown a variant of the method according to the invention, for the production of a slab comprising support beams of a height greater than that of the slab and intended to be partially embedded in floor.
  • FIG. 21 the surface of the ground which has been leveled
  • FIG. 22 a dig intended to accommodate a beam and on the well-leveled bottom 23 from which the structure 24 is put in place, constituting the frame of the beam , covered with a lost formwork 25.
  • the structure 24 is constituted by a wire mesh, and the lost formwork 25 consists of a sheet of cardboard in the shape of a U.
  • the spacers 26 of the mesh of the frame 24 are advantageously fixed to the formwork 25, so that it can easily be put in place at the same time as the trellis.
