Abstract

Method of manufacturing beams with rigid pre-tensioned reinforcement which, even alone, forms a beam resistant to stress and which comprises a full, perforated or lattice web, and at least one platform, characterized in that it is subjected to said reinforcement rigid to a traction substantially parallel to its longitudinal axis, in at least part of its length, applying two forces or groups of forces whose results are equal and opposite, maintaining these forces or groups of forces while covering concrete with at least one part of the rigid reinforcement comprising at least a fraction of its fibers under tensile stresses, suppressing, after hardening of the concrete and its solidarity with the rigid reinforcement, the forces or groups of forces mentioned above, which is intended to pre-compress at least a part of said concrete.
