Abstract

This invention relates to a monolithic foundation (1) system with homopolymer/resist ant aggregate pavement with a semi-continuous configuration, which uses a pavement with load transfer elements (5) for the induction of joints. It is essentially characterized in that it comprises a foundation (1) having high-density expanded polystyrene blocks, which supports a semi -continuous cement concrete pavement, the pavement formwork being formed by the polystyrene blocks of the foundation. Each one of the load transfer plates (5) is comprised of two anchors (6) with two rebars (7) for alignment of a joint inductor (8), and a ball joint (9) which, at the load support moment, rotates anticlockwise and, at the support moment generated by the load transfer plates, performs a clockwise movement. The said ball joint releases the concrete slabs (4) from stress caused by bending/traction at the moment of load transfer, allowing the foundation to be unaffected by bending moments resulting from the load and thus making the slab (4) work essentially with compression stress. The existence of the said ball joints enables the foundation to be obtained by the said polystyrene blocks.

Claims

1. A monolithic foundation system with homopolymer/resistant aggregate pavement with a semi-continuous configuration, which uses a pavement with load transfer elements for the induction of joints, comprising a foundation having high-density expanded polystyrene blocks, which supports a semi-continuous cement concrete pavement, the pavement formwork being formed by the polystyrene blocks of the foundation.

2. A monolithic foundation/pavement system according to claim 1, wherein the polystyrene blocks having dimensions as established in the design are manually laid.

3. A monolithic foundation/pavement system according to claim 1, further comprising a load transfer plate comprised of two anchors with two rebars for alignment of a joint inductor and a ball joint which, at the load support moment, rotates anticlockwise and, at the support moment generated by the load transfer plates, performs a clockwise movement.

4. A method for the execution of a foundation/pavement according to claim 3, comprising:

releasing, by said ball joint, of the concrete slabs from stress caused by bending/traction at the moment of load transfer, allowing the foundation to remain unaffected by bending moments resulting from the load and thus making the slab work essentially with compression stress.

5. The method for the execution of a foundation/pavement according to claim 4, further comprising positioning the said ball joint under the joint inductor and its centre is aligned with the vertical axis of the joint formed by the said inductor.

6. The method for the execution of a foundation/pavement according to claim 4, further comprising sealing the joint for protecting the foundation against chemical agents/diluents, having a silicone-type insulating material injected over the inductor in order to provide complete insulation.

7. The method for the execution of a foundation/pavement according to claim 4, further comprising coating the foundation along its upper and lateral parts with a plastic material, in order to reduce from about 2.5 to 0.5 the friction coefficient of the slab concrete when contracting and simultaneously protect the polystyrene blocks from possible spillages of liquids at the surface.
