BUILDING SLABS PAD

Abstract

A building slab pad in the form of a square plate is divided into four analogous sections, each section being formed by four linear projections on the top surface that run from the center of each edge and converge in the center of the pad. On each of the two side edges of the sections there is a trapezoidal protrusion respectively with a base narrower than the rest of the protrusion and a keyway respectively corresponding in shape to the protrusions, with two protrusions and two keyways alternating on each side edge of the pad. On the top surface there are linear top indentations running from the corners of the pad and converging in the center of the pad. On the underside are four linear bottom indentations running from the center of each edge to the center of the adjacent edge to form a square shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] As shown in the figures, the pad is in the form of a square plate and is divided into four analogous sections 1, 2, 3 and 4. Each section is formed by four linear protrusions on the top surface of the pad that run from the center of each edge and converge in the center of the pad.

[0034] On each of the two side edges of sections 1, 2, 3 and 4 there is a trapezoidal protrusion 1a, 1aa, 2a, 2aa, 3a, 3aa, 4a and 4aa respectively with a base narrower than the rest of the protrusion and a keyway 1b, 1bb, 2b, 2bb, 3b, 3bb, 4b and 4bb respectively corresponding in shape to the protrusions, with two protrusions and two keyways alternating on each side edge of the pad.

[0035] In addition, on the top surface of the pad there are linear top indentations running from the corners of the pad and converging in the center of the pad.

[0036] On the underside of the pad are four linear bottom indentations running from the center of each edge to the center of the adjacent edge to form a square shape.

[0037] The pad in each section 1, 2, 3 and 4 has a central circular hole 8. The pad is made of rubber material bonded with polymer adhesive. Polyurethane glue is used as an adhesive, while epoxy glue, acrylic glue or neoprene glue can also be used. The pad can be made with different dimensions to suit the size of the panels to be laid. The pad can be made in different thicknesses to suit the amount of water drained and the weight of the panels.

[0038] The pads are laid on a level, stable surface with drainage for the space under the panels. Then a system of inlets and outlets connects them to each other. A stable connection is obtained to prevent the plates from sliding apart 9. The edge and corner pads are easily cut by removing unnecessary sections. Linear upper recesses 6 and lower recesses 7 and central circular holes 8 facilitate water drainage. After connecting the pads and laying the boards 9 on them, the spaces between the boards 9 are filled with linear protrusions of the top surface of the pads, and the resulting final surface, such as a terrace, does not require grouting. Boards 9 are laid with their entire surface on pads which improves their stability.

[0039] The pad on the bottom surface may have four linear indentations 10 running from the center of each edge and converging in the center of the pad. Recesses 10 are used to accommodate electrical cables intended for outdoor use.
