ABSTRACT:
A factory for manufacturing concrete products, in particular prestressed concrete products, comprising a rotary supporting housing of a general cylindrical shape, having a horizontal axis of rotation and conveying moulds, for the concrete products, placed on its internal surface. The rotary housing comprises a circular carrier structure supported by means permitting the rotation of the said carrier, and a structure, resistant to longitudinal stresses, arranged in the interior of the carrier structure. The resistant structure comprises, on the one hand, longitudinal recesses adapted to receive sets of moulds, and, on the other hand, at one longitudinal end means for the attachment of reinforcement wires of the concrete products and, at its other longitudinal end, means for tensioning the reinforcement wires, such that the tensile stresses of these wires are taken up exclusively by the aforesaid resistant structure.
