Abstract

Prefabricated part in reinforced, prestressed or post-tensioned concrete for the construction of roofs, characterized essentially by being constituted by a body of section in "U", with a bottom and two walls preferably perpendicular to the first, which, as such the walls are of variable cross section, optionally on the internal face of said bottom projecting reinforcement ribs situated in a direction substantially transverse to the longitudinal axis of the piece and counting the walls with a series of ports flush with the internal bottom of the piece. U "and, on its external faces, with a series of lugs intended to ensure the best integration to the concrete that could be cast and to contribute to the support of upper reinforcing bars, as well as with a longitudinal fin flush with the lower face of the "U", which, when juxtaposed to the corresponding fin of a similar piece, constitutes the bottom of a formwork whose faces the walls are made up of the walls of the juxtaposed "U" pieces, in which the bars and concrete necessary to form a resistant rib of the roof can be placed, the bearing device being completed due to the possibility of joining rods through the openings. Aligned of several successive pieces, whose rods would be integrated to the resistant nerves by the actual concreting and to the bottoms of the pieces by the concrete to be cast between the walls of the "U" and the protruding nerves transverse to them.
