Definitions

  • the present invention relates to a prefabricated floor, said dry floor, comprising a set of prefabricated beams, parallel, spaced apart by a predetermined interval and supported by a bearing structure, and a set of prefabricated distribution slabs resting on said beams, the length of these slabs of distribution being at least equal to twice the interval between two adjacent beams.
  • concrete floors or the like having both industrial and domestic applications, are made from a set of reinforced and / or prestressed concrete beams, arranged in parallel in support on beams or load-bearing walls, and a set of interjoists arranged between the beams to close the bays, each interjoists resting on two adjacent beams.
  • the concrete or other similar product is directly brought on site and poured on the supporting structure formed by beams and interjoists to achieve a compression slab.
  • the operation of pouring the concrete directly on site is, therefore, time consuming, concrete, means implemented such as a mobile concrete plant, etc. In addition, this operation is subject to the vagaries of bad weather.
  • a first example is described in the publication FR 2 800 111 belonging to the same applicant, in which the floor consists of concrete joists between which are closely interjoined form complementary, the assembly of these elements forming the floor.
  • the interjoists carry loads on the two adjacent beams on which they rest without distributing them over the entire floor.
  • This disadvantage leads to unevenness of the floor, especially in the case of concentrated loads, such as at the level of the partitions. Therefore, this solution requires casting a specific screed to make up these differences in levels.
  • a third example is described in the publication DE 911 068 in which the floor consists of beams and slabs of constant thickness resting on the beams.
  • a system of tenons and mortises provided respectively on the web of the beams and in the slabs makes it possible to stiffen the floor in the horizontal plane.
  • the floor does not have a uniform surface because of the tenons and exposed mortises and does not meet the thermal requirements because of the small thickness of these slabs.
  • the present invention aims to solve these problems by proposing a new dry floor, requiring no compression slab or specific screed, both in the interim phase during the construction site, and in the final phase the resulting dry floor having a uniform surface and sufficient rigidity to avoid any parasitic deformation as much under the site loads as under fixed and operating costs in the final phase, while responding to seismic and thermal constraints.
  • the invention relates to a prefabricated floor as defined in the preamble, characterized in that the distribution slabs comprise grooves of section substantially complementary to that of the beams to fit on said beams.
  • the distribution slabs advantageously comprise at least on their longitudinal edges complementary forms of interlocking.
  • These distribution slabs may have a thickness substantially equal to the height of the beams.
  • These distribution slabs may comprise a solid structure, hollow, honeycomb or a combination of these structures. If they are hollow or honeycombed, they can be filled with at least thermally insulating filler material.
  • the floor may include interjoists arranged between the beams, the distribution slabs then covering the beams and interjoists.
  • the interjoists have transverse slots and the distribution slabs have side walls able to fit into these transverse slots.
  • the distribution slabs may be made by extrusion or molding, in at least one material selected from the group consisting of metals and its alloys, lightweight concretes, reinforced concretes, synthetic materials, composites, or a combination of these materials.
  • the present invention relates to a method of manufacturing a prefabricated floor, said dry floor 10, 10 ', that is to say not requiring the casting of a concrete slab or the like on the site, the dry floor obtained being intended to all types of buildings for both domestic and industrial use.
  • the dry floor 10, 10 ' comprises a set of prefabricated beams 1, preferably of reinforced and / or prestressed concrete, resting at their ends on a supporting structure 2, for example beams or load-bearing walls. These beams 1 are arranged parallel, spaced apart by an interval I or a predetermined pitch, delimiting spans 3.
  • the manufacturing method consists in covering these beams 1 with prefabricated distribution slabs 30-50, disposed adjacently and resting on the top of said beams 1, the longitudinal direction of these slabs 30-50 being perpendicular to the beams 1, in the measure where these slabs are longer than they are wide.
  • This mounting principle makes it possible to distribute the loads of the dry floor 10, 10 'uniformly over all of the beams 1, to avoid the problems of flatness defects and to improve the mechanical characteristics of the floor.
  • These distribution slabs 30-50 have a length L greater than the gap I between two adjacent beams 1 and for example equal to substantially three times this gap I to bear on four adjacent beams 1, as shown in Figure 1. This example of length L is not limiting.
  • the distribution slabs 30-50 may be aligned with each other or staggered as in the figures. They may also include complementary interlocking shapes on their longitudinal edges to be able to fit into each other as explained below, so as to ensure lateral retention of the slabs therebetween.
  • the distribution slabs 30-40 are placed directly on the beams 1 without interjoists, unlike the dry floor 10 'of Figures 6 to 8 in which the spans 3 are filled in prior to placing slabs 50 interjoists 60 including insulating.
  • the distribution slabs 30-40 used in the manufacture of this first embodiment of dry floor 10 can be in various forms.
  • the distribution slab 30 is profiled and has a thickness substantially equal to the height of the beams 1. It comprises in the lower part, parallel grooves 31 of section substantially complementary to the section of the beams 1, these grooves 31 being transverse to the longitudinal direction of the slabs 30. In the example illustrated, it comprises two grooves 31 solid in the middle part and two half-grooves 31 at the ends of the distribution slab 30, these grooves 31 being spaced apart from the interval I. Thanks to its construction, the distribution slab 30 rests on the top of the beams 1, at least partially fills the spans 3 defined between the beams 1 and extends to the heel 13 of these beams 1.
  • the distribution slabs 30 being nested on the beams 1 give the floor 10 a rigidity in the horizontal plane, improving the characteristics anti-seismic construction.
  • the distribution slab 30 comprises an open structure formed of a flat upper face 36 and two lateral faces 37, and is partitioned by four parallel inner walls 38 inverted T reinforcing the strength of the slab. Any other form may be suitable. It is obtained by machining, molding and / or extruding concrete and / or synthetic materials, composites, metals or a combination of these materials, and is filled by a filling material 35 closing the structure, such as for example an expanded polystyrene or the like, having in particular good thermal insulation performance. It comprises on one of its longitudinal edges a longitudinal rib 32 and on the opposite edge a longitudinal groove 33, of complementary dimensions to be able to fit into a longitudinal groove 33 and a longitudinal rib 32 of adjacent identical distribution slabs 30.
  • the distribution slab 40 is structured and has a thickness greater than the height of the beams 1. It comprises, in its lower part, parallel grooves 41 of section substantially complementary to the section of the beams 1, oriented transversely with respect to the length of the slabs 40. In the example shown, it comprises two grooves 41 solid in the middle part and two half-grooves 41 at the ends of the distribution slab 40, these grooves 41 being distant of the interval I. Thanks to its construction, the distribution slab 40 rests on the top of the beams 1, at least partially fills the spans 3 defined between the beams 1 and extends to the base of the beams 1.
  • the distribution slabs 40 being nested on the beams 1 give the floor 10 a rigidity in the horizontal plane, improving the characteristics anti-seismic effects of construction.
  • the distribution slab 40 has an upper face 46 and a lower face 47 planes and an inner honeycomb structure, the lower face 47 stopping at the heels 13 of the beams 1. It also has two side faces 48 which extend to at the base of the sole 12 of the beams 1. It is obtained by machining, molding and / or extrusion of concrete and / or synthetic material, composite, metal or a combination of these materials, and can be filled or not with a material 45, for example an expanded polystyrene or the like, having in particular good insulation performance thermal.
