         5 . Device for being positioned in floating floor slabs and system for the installation thereof in accordance with  claim 1 , characterized in that the meshes will be positioned such that their upper bars are perpendicular to the rods and above same. 
     
     
         6 . Device for being positioned in floating floor slabs and system for the installation thereof in accordance with  claim 1  having first and second meshes, characterized in that the first mesh will be positioned above the rods arranged on the sides of the cube which have the tubes closest to the base ( 1 ,  1 ′). 
     
     
         7 . Device for being positioned in floating floor slabs in accordance with  claim 6 , characterized in that said first mesh comprises two aligned fabric surfaces, said surfaces being bonded by a rod inserted in the two adjacent cubes of the mesh surfaces ( 5 ). 
     
     
         8 . Device for being positioned in floating floor slabs in accordance with  claim 6 , including rods inserted into said tubes, characterized in that the second mesh will be positioned above the rods of the upper tubes of the other two sides of the cube ( 2 , 2 ′). 
     
     
         9 . Device for being positioned in floating floor slabs in accordance with  claim 1 , characterized in that rods are situated in the lower tubes of the other two sides of the cube when major loads are expected to be supported by the floating slab ( 4 ,  4 ′). 
     
     
         10 . Device for being positioned in floating floor slabs in accordance with  claim 1 , characterized in that rods are situated in the cubes next to the corners of two mesh surfaces, said rods linking the adjoining cubes, and arranged in the upper tubes parallel to the tube at which the first mesh ( 3 ,  3 ′) has been positioned. 
     
     
         11 . A system for the positioning and the installing devices in floating floor slabs having a poured concrete base with welded wire fabric composed of at least one layer, said layer being in the form of a mesh grid, including rebar rods adapted to be connected to said devices within said floating floor slab, said devices after the setting of concrete, adapted to accommodate shock absorbers, including the steps of
 providing a plurality of devices in the shape of a cube with sides, the base widths of which are less than the grid of the mesh, and whose height is integral with that of the concrete base, each cube having horizontal tubes on its sides, whose lengths are less than that of the width of the cube, and with a cross section suitable for the insertion of said rebar rods,   mounting said devices in said fabric before pouring the concrete base by inserting said rebar rods through said upper an lower tubes, and   pouring said concrete base, allowing it to set, and then installing shock absorbers in said cubes.
