Abstract

Prefabricated set for the forging of reticular ceilings of reinforced concrete, prestressed or post-tensioned, which is essentially characterized by being constituted by two main pieces, determined one by a joist and formed the other by a complementary cover, the first 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 between said walls and said bottom a plurality of pairs of properly oriented piers, which give rise to some enclosures transverse to those walls, the upper edges of which are flush with those of these tabiquillos, the latter being alignable when the roof is structured and fit to receive horizontal reinforcements and concrete "in situ", with the two walls of the joist running through by luminaries located in communication with the enclosures and next to the line of uni n between the bottom and the wall, lumbreras that are destined to the laying of those reinforcements, which, with the poured concrete, form transverse nerves within the repeated enclosures, being the second basic piece of the set composed by the aforementioned cover, determined by a simple closing plate of the hollow delimited by the bottom of the beam, by the two walls of the same and by the external face of the tabiquillos.
