Abstract
A method for the manufacture of prestressed reinforced concrete pieces of prismatic shape and of substantial length provided with juxtaposed longitudinal cavities destined to the floor slab characterized in that it comprises the following operations: provision of a suitable mold for the casting of the concrete; provision of anchor rods for the reinforcement of the finished part; placing males in the positions corresponding to the longitudinal openings, these males being constituted by rubber tubes capable of swelling up to the diameter corresponding to the openings to be obtained; tensioning of the reinforcing wires; concrete pouring; deflating the males and removing them once the concrete has taken the suitable body; slackening of the reinforcement wires after the concrete has been set so that it is subjected to compression and finally to the long piece thus obtained at suitable lengths.
