Abstract

Prefabricated set for the forging of reticular roofs of reinforced concrete, prestressed or post-tensioned, which is essentially characterized by being composed of two main parts, one determined by a joist and the other formed by a complementary cassette, the former presenting the conformation of a " u ", with a bottom and two walls substantially perpendicular to the first, which, like such walls, is of variable cross section, including in said walls, in the line of unión of the same with the bottom, luminaries close to the surface of that bottom, these luminaries being intended for the horizontal laying of reinforcements transverse to the beam, at the bottom of which, as in their walls, there may be a series of reinforcing bars for the concrete to be cast on the whole upper plane of the structure, serving the reinforcements of the bottom to fix the cassette or complementary component, which presents the section of a a "U" inverted, whose front faces are arranged against the lateral walls of the same beam, while the side faces are aligned with each other and with respect to the open windows in those same walls, thus forming shuttering for transverse nerves that are obtained by pouring concrete in the space between casetones and on the reinforcements that cross those ports.
