Abstract (en)
[origin: CA1176071A] This invention relates to a prestressed concrete structure which behaves like a hollowed out slab. The structure combines a lattice work structure and a prestress by external cable, maximally optimizing the advantages of these two techniques. The Figure represents a part of the floor of a bridge according to the present invention. The floor comprises to tables 6 and 7 which are joined by a lattice work composed of pyramids P. Prestressing cables 8, 8' and 9' pass between the tables outside the concrete of the bars of the pyramids. The present invention is used for the construction of bridges, roofings and floors.
