Improved floor slab, characterized essentially by the fact that it comprises a plurality of identical hollow ceramic pieces, provided in their upper base with protruding ribs that define low-height channels, presenting on both sides of the lower base, opposite to that mentioned, separate heels of u-section, run on the longitudinal edges of the pieces, existing on the sides of the same, protruding and longitudinal heads; whose parts coupled to the top by their emptied ends, constitute rows; and because two or more rows in a parallel arrangement meet in such a way that the adjacent heels form a longitudinal channel for a reinforced concrete rib that sets in the factory, and with a section of the outer heels of the rows, a filling of reinforced concrete, of equal height to the heel, being constituted a transportable integral panel to the work, cooperating with identical others by inclusion in situ in the resulting channels, of unión, a concrete casting, through which resistance is achieved additional for the resulting slab and a crack-proof monolithic.
