Abstract

Improvements in the manufacture of reinforced steel and/or concrete beams, in which to prevent the formation of cracks due to tensile stresses in the concrete, this is prestressed with compression, characterized in that a reinforcing part is prestressed with compression separately consisting of concrete and iron reinforcement preferably, the reinforcing part presenting approximately a length corresponding to the area in which tensile stresses are expected in the plate or associated head of the beam to be reinforced, and by that the reinforcing part is fixedly connected to the beam at its ends.
