Abstract
This disclosure relates to the extension of a portion of a deck using deck segments, by means of a cable stayed beam resting on a front hinged support and on a rear support. In a first phase, the overhanging segments are suspended from the beam in a manner known per se and the part 5a of the beam which is downstream of the front support 6 is maintained substantially steady. In a second phase, the segments are joined to said portion by producing a prestress accompanied by a progressive swinging movement by said rear part of the beam. This invention is used for the construction of the deck of a bridge.
