Description

    Field of the invention
  • The technical field of the present invention pertains to a device, which is integrated into the framework of floating slabs, as an instrument for raising the slab once the concrete has set. These floating slabs are arranged in constructions that require an insulation of the central block, as they may be the bases at which are situated electric transformers, air conditioning units, bowling alleys and, generally, sites at which it is desired to avoid the transmission of vibrations and impact noises.
    • Background of the invention
  • The system of creating floating slabs by means of distributing metallic containers in welded wire fabric in the form of cubes that are within the forging is known. The raising phase occurs once the concrete has set, and shock-absorbing elements are positioned in the cavity, which are coupled under beveled structures that are located in two of the corners thereof. In this way, the raising of the floating slab will be achieved to the extent desired by means of the pressure of the shock absorbers in its upper part.
  • The welded wire fabric is usually formed by two meshes or rebar surfaces, each of which are created by bars that intersect one another at right angles, forming grids, whose points of contact are joined by welding. These are positioned superimposed, trying to align the grids of the two meshes for the correct insertion of cubes which have a height similar to that of the welded wire fabric, and are positioned within the two caps of same so that, after the setting of the concrete, they are close in the forging. For this purpose, a plurality of metallic rods are installed welded on the surface of each cube in the horizontal direction which protrude from their structure. In fixing to the rebar, in order to avoid the displacement thereof in the pouring phase of the concrete, once in the grid, the rods are fastened to the welded wire fabric by means of wires. This involves a lot of work for the operator in the positioning and a limited rigidity of the system, causing the cubes to move when the concrete is poured or by the operator's own movements within the rebar. If the setting occurs with any of these elements displaced or twisted, there will be a weak zone at this point which may cause the fracture of the floating slab in the raising phase.
  • The grid of the welded wire fabric is produced by having different proportions. The prior-art system has the drawback that the rods welded to the structure of the cube are arranged so that they cover the grid in every case, to facilitate its bundling by means of wire. For this the operator usually has problems at the time of fitting the cube in the welded wire fabric, and has to shorten the rebar to make a suitable cavity. Apart from the labor-intensive work that it involves, it results in a structure that is hazardous to the work zone, which the ends of the rods welded together with the cuts made in the rebar constitute, with many sharp points, with risk to the operator in the work of positioning the wires or by the fact alone of being situated on the structure.
  • The welded wire fabric is manufactured in different extension dimensions for the different positioning sites. For this, the bonding of one surface of the welded wire fabric with those [surfaces] which follow it in the work is necessary. It is equally necessary to fix the corners of the layers of the welded wire fabric, if the last layer goes through zones remote from the center, this force then causes the structure to rise.
  • Another type of element is known for arranging in the forging that is made up of a metallic cylinder with walls of considerable size, within which the shock absorber is arranged, having two horizontal projections in its contour for being situated in the rebar. The complexity of this structure makes the manufacture thereof very expensive, and the securing in the welded wire fabric, in spite of the weight that it has, is insufficient.
    • Description of the invention
  • The present invention that is proposed fully solves the problems mentioned by presenting a device in the form of a cube which has various horizontal tubes in its perimetral structure, at various levels, suitable for rods being inserted therein, which project from the sides of the cube for placing the different layers of welded wire fabric above them. In this way, the first layer of the welded wire fabric will rest on the rods arranged in the lower tubes of the cube, which are facing on two of its sides; a second welded wire fabric arranged above the rods of the upper tubes, placed on the other two opposite sides of the cube.
  • The bonding of the different mesh structures of the work is carried out by means of the rods installed in the lower tubes which support the first welded wire fabric, which connect the cubes of the adjoining mesh surfaces.
  • Rods will be placed in the upper tubes parallel to the above tubes for the bonding of two adjacent cubes which are close to the corners of two welded wire fabric surfaces. This upper linking together will prevent the raising of the mesh when a pressure goes or is applied outside of the central zone.
  • The object of the present invention is accomplished with a lid and a base for the interior insulation in the pouring of the concrete.
    • Description of the drawings
  • To complement the description that is being provided and to aid in a better understanding of the features of the present invention, the present specification is accompanied by drawings showing the preferred embodiment, in which, in an illustrative and nonlimiting nature:
    • Figure 1 shows the left elevation (A), front elevation (B) and plan view (C) of the cube that is the subject of the present invention.
    • Figure 2 shows a view of the cubes in a first phase of positioning.
    • Figure 3 shows us a view of the positioning of the first mesh in the work with two surfaces of same aligned.
    Preferred embodiment of the invention
  • Viewing the figures shown, it can be seen how the device for positioning floating slabs is composed of a metallic cube, whose base will have a smaller dimension than the surface of the grid of the mesh and have a height in relation to that of the forging; and in its perimeter it has identical tubes which are preferably attached to the structure by means of welding.
  • Each side has two pairs of tubes placed in parallel, horizontally, and same have proportions that do not exceed the length of the side (Figure 1), (C), and they are placed on each side at a same position with respect to its side of the opposing cube (A, B); and the tubes of two of the opposing sides (A) are situated at a different level with respect to the other two sides (B), and the latter are situated closer to the base (1, 1') and closer to the height (3, 3') of the cube than the tubes of its adjoining sides (4, 4') and (2, 2').
  • The first mesh of the structure of the welded wire fabric will be situated above the rods of the lower tubes, according to Figure 2.
  • In the adjoining meshes, the rods of the lower tubes will be inserted therein in both pieces, connecting both surfaces of the structure (5).
  • The mesh is formed by means of arranging bars vertically with other horizontal bars, some on top of others, securing the bonding at the points of contact by welding. The rods of the lower tubes will be situated on the same plane and parallel to the lower bars of the mesh, holding the bars perpendicular to the above ones.
  • The second mesh has to be positioned in the same way, with the rods installed in the upper tubes which are on the other two sides of the cube (2, 2'). Also, in this way, with the rods on the same plane and in parallel to the lower bars of the mesh.
  • The separation between the lower tubes and upper tubes for positioning the mesh will be sufficient for the entry of the concrete, on the understanding that there may be little separation that the cavities will have in the pouring which will put the consistency of the future floating slab at risk.
  • In the cubes belonging to two mesh surfaces that are located close to the corners, rods will be placed and inserted in the upper tubes which are on the same side as the lower tubes, whose rods support the first mesh, and inserted in the two adjacent pieces (3, 3'). It will also be used for anchoring the structure and the mesh is not raised when exerting pressure in an opposite zone. The first welded wire fabric is shown only in Figure 3, and it has to be understood that the second one will be situated superimposed and in the manner that is described.
  • The figure shows two joined meshes (I, II) beginning at the joined corners, and it has to be understood that the surfaces of the same are not shown complete in the horizontal direction.
  • The other two tubes that are in the structure of the cube, arranged parallel to the upper tubes for the installation of the rods that support the second mesh and in a plane lower than those (4, 4') will be used for the installation of other additional rods when the slab has to support major loads.
  • The cube has a lid and a base coated with rustproof paint, and both are assembled by compression to avoid the entrance of the pourable concrete mix. As a complement, the lid is arranged sealed with silicone. The lid and base are painted different colors for quickly checking before pouring the concrete whether any of the cubes are in the incorrect position.
  • When the concrete has set, the lids of the cubes will be removed, and shock absorbers will then be placed which will make the raising of the slab possible. In this most suitable embodiment, another shock absorber, in this case, a highfrequency, Silent block type absorber, will be placed on the bottom, which will facilitate the movement of the shock absorber arranged above same.
  • It should be understood that the present invention was described according to the preferred embodiment of same; therefore, it may be susceptible to modifications in shape, size and materials, provided that said changes do not substantially vary the features of the present invention as they are claimed below.
