US 7,121,053 B2 · Reinforced slab made of cement conglomerate, method for the manufacture thereof and associated reinforcing structure

Abstract

A reinforced slab, in particular able to withstand concentrated loads, has a substantially flat reinforcing structure (20) which is situated at a distance from the bottom (12) of the mould (10) and arranged at a height such as to allow embedding of said reinforcing structure (20) within the end product (40), said reinforcing structure consisting of a sheet oriented substantially parallel to the surfaces of said slab and having a plurality of holes or openings. Preferably said sheet is provided with stiffening ribs and the edges of the holes or openings are folded in the form of a “U”. The method for manufacturing the reinforced slab is a method known as “Terastone”, except for the step involving insertion, in the forming mould, of the reinforcing structure which is positioned at the desired height by means of support feet.

Dependent claims

A reinforced slab made in a mould, the reinforced slab comprising:

a mixture formed of a granulate of a predefined grain size and a cement binder formed of cement and water, the mixture formed into a layer comprising substantially no entrained air and having a flexural strength of at least 15 N/1 mm2;
an upper and a lower main surface, the main surfaces being substantially flat and parallel to one another;
a reinforcing structure consisting of a sheet of a metal provided with a plurality of holes so as to allow the free passage of the mixture, the sheet being entirely embedded in the body of the reinforced slab and being arranged substantially parallel to the main surfaces thereof, the sheet comprising
a plurality of feet to space the sheet from the mould,
lateral projections for centering the sheet with respect to a peripheral edge of the mould;
wherein the sheet is arranged at a given distance from the neutral axis of the associated cross-section.
