<p>The panel has an upper horizontal central band (1) with longitudinal ribs (4, 4) separated by a transversal notch (5). Lateral cores (2, 2) extend toward bottom and outside the band, and have longitudinal pressed stiffeners (6, 6). Lower horizontal flanges (3, 3) laterally extend the cores and extend outside the panel. The stiffeners are placed in portions of the cores working in compression when the panel covers the concrete. An independent claim is also included for a floor having a concrete slab on a self-supporting formwork.</p> |
