Improvements introduced in the construction of prestressed structures comprising a structural member having a conduit or channel extending therethrough or along the same, or a plurality of said structural members arranged end to end with their aligned conduits or channels, being arranged within the conduit or channel extending over the entire length of the structure to prestress a plurality of tensile steel cables of high tensile strength and multiple wiring, said cables being anchored in anchoring means at each end of the cable. the structure and being arranged between said anchoring means in substantially parallel layers, one or more spacer members having openings therethrough are also disposed in the conduit or channel, through which the cables pass in order to keep the cables spaced apart and located in said substantially parallel layers, the anchoring means comprising less at one end of the structure a plurality of anchoring devices each intended to anchor one of the cables, the cables having been individually tensioned and then anchored in the tensioned position by their associated anchoring devices, the thrust of all the cables being transmitted. anchoring devices cited to the structure through a common thrust plate that surrounds the open end of the conduit.
