  • Concrete slabs comprising a flat lower surface or provided with anchoring means and an upper surface consisting of studs regularly spaced on the same plane.
  • the space arranged between the studs can receive soil sown with grass, which is then protected by the studs which support the pressure of the loads applied to the ground by pedestrians, motor vehicles or others.
  • the floor covering slab according to the invention aims to remedy the drawbacks of existing slabs, while offering new possibilities.
  • it comprises at least two walls separated from each other by bracing structures participating in the constitution of at least one chamber capable of receiving a filling product and each of which is integral with the other. by being linked to it by its peripheral edges and, possibly, by its parts in contact with the bracing structures.
  • the bracing structures are an integral part of one of the walls.
  • the filling product for the slab chambers can advantageously play a ballasting role which ensures that the slabs remain on the ground, without it being necessary to glue them. Their installation is considerably facilitated.
  • this slab is made of a flexible and elastic, moldable, injectable, extrudable or thermoformable material, such as a polymer, elastomer, or other suitable plastic material.
  • the bracing structures are ribs or partitions possibly delimiting separate chambers.
  • the bracing structures are solid or hollow studs, regularly spaced.
  • this slab its upper and lower walls and the bracing structures constitute a single piece capable of being manufactured by blowing or rotational molding.
  • the filling product can then, if it is sufficiently fluid, be introduced into the slab through holes provided for this purpose and possibly fitted in the upper wall.
  • its lower wall and its bracing structures constitute a first part
  • the upper wall constitutes a second part, fixed to the first by gluing, welding, stapling, riveting or in any other suitable way.
  • each part can be executed by molding, blowing or injection and the filling product is easy to put in place before the two parts are assembled.
  • each tile has, along its peripheral edges, an alternation of grooves and ribs oriented in opposite directions, of so that each groove of a slab can be engaged on the rib of an adjacent slab.
  • the present invention also aims to allow the realization of a technical floor rehabilitation low cost by providing a slab easily adaptable to the characteristics of the desired technical floor.
  • studs are provided, with the same distribution, on each of the opposite faces of the upper and lower walls of the slab, the height of the studs of one of the walls, for example the upper wall, being constant, while that of the studs of the other wall, for example the lower wall , is determined by the need for the installation, means being provided to facilitate the correct positioning of the upper and lower walls of each slab.
  • the edges of the tops of the studs of one of the walls, preferably of the studded wall of constant height are provided with engaging projections on the tops of the studs of the other wall.
  • this paving can be covered with a carpet with the interposition of sheet metal plates for grounding.
  • the slab which it relates also aims at the realization of technical floors, simultaneously with the construction of the buildings concerned, and allowing the installation of all the pipelines necessary for the operation of this building.
  • the known technical floors which, like those of rehabilitation, must provide easily accessible interior voids, are generally constituted by rigid, self-supporting, square or rectangular slabs, most often in wood or steel, and carried, at each of their four angles, by a jack of adjustable height and also supporting the adjacent angles of the three adjacent slabs.
  • Wooden slabs have the drawback of not allowing grounding on their own and of requiring them to be placed in sheet metal tubs, as for steel slabs, given the shape in a box, they have the major drawback of not ensuring sound insulation. In addition, these two types of slab are of a high cost price.
  • the bracing structures of this slab which is of the self-supporting type intended to be supported, in each of its angles, by a jack of adjustable height which also supports the adjacent angles of the neighboring slabs, are constituted by a metal frame. ventilated, in the form of an umbrella whose upper flat part is embedded in its upper wall, and whose lower ends of the branches directed vertically downward, are linked to a sheet metal container covering the external face of its lower wall.
  • this slab whose upper face is made of insulating material has the advantage of having a metal lower face allowing it to be earthed.
  • this slab is advantageously produced by rotational molding after placing, in the mold, its metallic elements formed by the lower tank and the bracing structure.
  • the lower tray When this slab is large, and its mechanical characteristics require it, the lower tray has concentric intermediate steps increasing its depth from its periphery, towards its center and the reinforcement which constitutes its bracing structure has as much concentric intermediate rows of vertical branches, of appropriate length and position that the tray has steps, each row being designed to fit into a step.
  • the metal frame constituting the bracing structure and the tray can be assembled together in any suitable manner and in particular by welding or by simple wedging.
  • the steps can be circular or polygonal, such as square or rectangular.
  • the filling product of the slab chambers is determined according to the needs of the user.
  • the filling product consists only of a ballasting product.
  • this slab when this slab is intended for an exterior or interior floor covering but sufficiently lit, its upper wall has a plurality of holes and the filling product comprises a fertile soil sown with '' a lawn, dwarf bamboo or other plants able to grow through these holes.
  • the earth is covered with a trellis of fibers preventing the grass from pushing straight and forcing it to push in a sinuous way through this trellis.
  • This arrangement which can only be envisaged with two-part slabs, makes the lawn less fragile when flexed and therefore more suitable for being walked on.
  • the upper face of this lower wall has fine reliefs of the granite type.
  • this slab which is of the type whose upper wall has a plurality of holes and whose filling product of the internal chamber comprises a fertile soil sown with seeds of plants, such as lawn, on the one hand, its lower wall has a plurality of bosses provided with slots or openings and directed downwards and, on the other hand, it is associated with a sealed container capable of accommodating it entirely and on the bottom of which it rests by the tops of the bosses of its lower wall, the free volume provided, thanks to the latter, between the bottom of the tank and the lower wall of the slab being used to constitute a reserve of water.
  • the interior lawn supported by slabs of this type can be gently sprayed from above, the water reaching the tanks through the perforations in the upper walls of the slabs, the fertile soil and the slots or through the bosses in their lower walls.
  • the filling product comprises elastic particles and / or a liquid and the bracing structures are made of an elastic material and / or have a shape giving them the desired elasticity characteristics. It is thus possible to produce floors endowed with a very appreciable flexibility.
  • the slab according to the invention essentially comprises two opposite walls, one upper 2, the other lower 3, one of which, preferably the lower one 3, carries bracing structures now separated from it the other wall 2.
  • These bracing structures are constituted, in addition to the four ribs 3a, 3b, 3c, 3d, constituting its peripheral edge, by ribs 4 or studs 5 interiors, visible in Figure 1.
  • These structures also have the function of creating inside this slab, that is to say between its upper 2 and lower 3 walls, one or more chambers 6 able to receive a filling product.
  • the upper 2 and lower 3 walls of this slab are further provided with means allowing them to be assembled to one another.
  • the two constituent parts of this slab namely its upper wall 2 and its lower wall 3, can be made of any suitable material but they are preferably made of a moldable or injectable material, flexible and elastic, such as an elastomer, polymer or any other suitable plastic material.
  • this slab is produced in two separate parts assembled together, one can envisage its manufacture in one and the same part, produced by molding or rotational molding.
  • the ribs 4 and interior studs 5 are full and are obtained directly by molding or injection with the bottom wall 3 and its peripheral ribs 3a to 3d and the means for assembling the top walls 2 and lower 3 are made up by pins 7 carried by the lower face of the upper wall 2 and by wells 8 opening into the upper face of the peripheral ribs 3a to 3d of the lower wall 3, each pin 7 of the upper wall 2 being intended to be engaged in one of the wells 8 of the lower wall 3.
  • the upper wall 2 ′ is flat, as in the example in FIG. 1, but it has at least perforations 9, the reason for which will be explained later.
  • its lower wall 3 ′ supports bracing structures 5 ′ in the form of studs which are obtained by deformation or forming and which, therefore, are hollow.
  • Each stud 5 ′ which has the shape of a truncated cone, has, at its apex, a central perforation 11 each of which coincides with a perforation 9 of the upper wall 2 ′ when these two walls are applied one against the other. 'other in position of use of the slab.
  • These perforations 9 and 11 are used to fit assembly rivets 12, each of which is engaged in a set of perforations 9 and 11 and remains captive therein by snap-fastening, as can be seen in FIG. 2.
  • the hollowed out shape of the studs 5 ′ constituting the bracing structure of the upper wall 2 ′ gives this slab a theoretically greater flexibility than that of the previous example.
  • this hollowed out shape of the pads 5 ′ allows a saving of material having a favorable impact on the cost price of the slab.
  • the interior chamber 6 is filled with fertile soil 13 sown with grass and, to allow the latter to push above the upper wall 2 ′, the latter, as indicated in 14, has widely dimensioned orifices 15.
  • a trellis of fibers 16 is placed on the ground 13 by being, for example, sandwiched between the upper 2 ′ and lower 3 ′ walls of the earth.
  • the upper face of this lower wall 3 has fine reliefs 3 ′′′, as illustrated in dashed lines in FIG. 3.
  • this slab also has, in the case of the aforementioned use, that is to say as illustrated on the left-hand side of FIG. 2, the advantage of allowing the installation of tubes of sprinkler 17 provided with perforations 17a and capable of distributing irrigation water in a programmable manner.
  • the interior chamber 6 of this slab is filled with any ballast product such as sand and, as this part of FIG. 2 shows, its constitution allows the establishment, before assembly of its walls 2 ′ and 3 ′, of pipes such as pipes 18 for the distribution of sanitary or heating water or of any other heating or refrigerating fluid. It also allows the installation of electrical pipes 19 intended for heating or for the distribution of electricity.
  • this slab By its possible constitution in translucent material and because of its shape, this slab also makes it possible to set up, either in some of the interior chambers 6, or in the recesses of studs 5 ′ or ribs 4, bracing structures, light sources.
  • this slab is intended for the constitution of a soil 3, of ground for which great flexibility is desired, it is still possible to improve its characteristics of flexibility and elasticity by mixing with the sand particles of elastic material 22. It is also possible, instead of sand 20, dispose of the liquid such as water which will ensure a better distribution of the compressive forces on the particles 22.
  • Figure 3 shows, on an enlarged scale, a particular embodiment of the edges of this slab, intended to allow assembly between them, by mutual interlocking, adjacent slabs, while ensuring a certain tightness to this assembly.
  • two of the peripheral ribs of the lower wall 3 ⁇ of this slab for example the rib 3a, is provided with an extension 3′a bent twice at right angles so as to provide on all of its length, a groove 23 open downwards and engaging on the contiguous peripheral edge 3c of the adjacent slab.
  • This arrangement is particularly advantageous when the paving considered is an outside paving in which it is desired to grow grass or the like, which requires the sprinkling of the earth possibly constituting the filling product of the interior chamber 6.
  • a film waterproof 25 which may consist of a plastic film or, optionally, if it is desired to improve the flexibility of this paving, a sheet formed by two plies of plastic material with cavities between them filled with air.
  • Figures 4 and 5 illustrate an embodiment of this slab intended for the formation of a technical rehabilitation floor, that is to say a floor to be laid on an already existing floor and in thickness which are provided voids intended for the circulation of electric cables or other pipes, in particular for connecting to a central unit all the workstations of a computer installation or the like.
  • this installation being capable of evolving over time, it is essential that the voids are easily accessible.
  • This embodiment of the slab according to the invention also aims to allow the production of technical floors adapted to the computer or other installation concerned, that is to say whose thickness is exactly determined by the characteristics of this installation. Indeed, the extra thickness caused by the installation of a technical rehabilitation floor is generally troublesome, and it is therefore advantageous that it is limited to its lowest possible vapor.
  • the bracing structures are, as in some of the examples described above, constituted by studs, but , in this embodiment, not only studs 5a are provided on the lower wall 3 of the slab, but studs 5b are also provided projecting from the underside of the upper wall 2.
  • the studs 5a and 5b having the same distribution on each of the walls 2 and 3 so as to be placed end to end during the assembly of these two walls of a slab.
  • the studs 5a and 5b are of generally frustoconical shape, which has the effect of facilitating the demolding of the walls 2 and 3 by creating a draft.
  • the intervals between the studs 5a and 5b provide empty spaces in which it is entirely possible to circulate pipes, such as electrical pipes 19 or for transporting other fluids 26.
  • the height L of each empty space provided for the passage of a pipe 19 or 26 results from the sum of the heights of the studs 5a and 5b.
  • all the upper walls 2 available to this installation are provided with studs 5b of the same height while there are several types of lower walls 3 whose studs 5a are of different heights.
  • these means consist of projections 5′b provided at the periphery of the tops of the pads 5b, preferably with a regular angular distribution, so as to ensure a partial nesting of the pads 5b on the pads 5a and thus prevent any relative displacement of one of the walls 2 or 3 relative to each other, in a direction parallel to their assembly plane.
  • this paving can be covered with a carpet 27 with the interposition of plates 28 made of metal sheet for earthing.
  • FIGS 6 to 9 illustrate another alternative embodiment of this slab, intended to allow the realization of technical floors simultaneously with the construction of buildings and which, like the previous ones, must allow the establishment, maintenance and all modifications any pipes necessary for the operation of these buildings.
  • These originally constructed technical floors must, like the previous ones, provide easily accessible interior voids but, in addition, the slabs that compose them, must be self-supporting, that is to say they must be able to support the loads to which they are subjected by being themselves supported, either by their four angles, for example by jacks of adjustable height, each of which supports the four angles of four adjacent slabs, or by their lateral edges, by means of angle profiles or T-shaped, arranged so as to form a grid, and which are themselves supported by cylinders of adjustable height placed in correspondence of the angles of the slabs, that is to say crosses of the profiles.
  • each self-supporting slab is supported, at each of its angles, by a jack 29 of adjustable height without the intermediary of angles or T-profiles forming a grid, but it is obvious that profiles of this type could just as easily be interposed between the slabs and the jacks 29.
  • the bracing structures are constituted by an aerated metal frame 5c perfectly visible in Figures 6 and 7 and which, in this example, is formed by a lattice of metal wires, having a flat part 5′c embedded in the upper wall 2 of the slab, and end portions 5 partiesc, 5 ′′′ c, 5 ⁇ ⁇ c or branches oriented vertically downwards so as to bear against the internal face of the lower wall 3 of this slab.
  • the lower ends of the vertical branches 5 ⁇ c to 5 ⁇ ⁇ c are linked to a tray 31 made of metal sheet intended to cover the lower wall 3 of this slab externally, facilitating its earthing.
  • This slab can obviously be easily produced by rotational molding after installation, in the mold, prior to the rotational molding operation, of the tank 31 and of the frame 5c.
  • the tank 31 is shaped so as to have a high moment of inertia.
  • this high moment of inertia is obtained by the arrangement, in the bottom wall of the tank 31, of concentric steps 31a, 3lb increasing its depth from its periphery in the direction of its center.
  • the frame 5c has as many concentric rows of intermediate vertical branches 5 ⁇ c, 5 ′′′ c as the tray has steps 31a, 31b.
  • the length of the vertical branches 5 ⁇ c, 5 ′′′ c is adapted to the depth of the corresponding part of the tank 31, and its position is determined so that each row of branches fits into a step.
  • connection between the frame 5c and the tank 31 can be carried out in any suitable manner, but it is advantageously carried out by welding.
  • the steps 31a and 31b of the container 31 can be square like the perimeter of the slab or even circular.
  • FIG. 10 illustrates an alternative embodiment of the slab of FIG. 2, that is to say an alternative embodiment of the slab of the invention in the case of its application to the production of a turf and more particularly in the case where this lawn is placed on an indoor or sheltered floor.
  • the lower wall 3 ′ of this slab has an interior chamber 6 formed in the intervals between frustoconical conical studs 5 ′ which constitute its bracing structure.
  • the bottom wall 3 ′ has, between the studs 5 ′, directed upwards, a plurality of hollow bosses 32 directed downwards, and the side walls of which are provided with slots or openings 33.
  • the lower wall 3 ′ of this slab is associated with a sealed container 34 capable of accommodating it entirely and on the bottom of which it rests by the tops of the bosses 32.
  • the free volume 35 formed, thanks to the bosses 32, between the wall lower 3 ′ of the slab and the bottom of the tank 34 is used to constitute a reserve of water.
  • the upper wall 2 ′ of this slab is perforated as in the example in FIG. 2, and it can be associated with it for the same reasons, a fiber mesh 16.
  • the irrigation water can reach the free volume 35 of water reserve quite simply through the fertile soil 13 filling the chamber 6 and the slots 33 of the bosses 32.
