<p>The invention relates to a novel sheet which is intended for roof casting and which is characterised in that numerous clamps or protuberances are provided near the surface thereof, which terminate in the form of a tear, enabling same to be incorporated into reinforced concrete similarly to rods. In this way, the aforementioned clamps or protuberances are immersed in the reinforced concrete and, consequently, dispense with the need for rods or wires. The constituent parts of the sheet comprise numerous clamps which are repeated in a regular manner and which extend into a rounded protuberance, said assembly forming an inverted-tear-shaped silhouette. As a result, the invention is suitable for use in the field of structural sections used for the construction of frameworks.</p> |
