摘要： This invention relates to an arrangement for projecting cantilever sections of multi-sectional bridge supporting structures of steel or prestressed concrete forming the superstructure of the bridge which is supported on bridge piles. The arrangement includes at least one traveling auxiliary beam movably carried on and arranged above the superstructure for spanning between superstructure sections. Two concreting scaffolds each comprising a supporting part having crossbeams and rollers are arranged above the superstructure and carry a platform which is arranged below the superstructure for carrying casings to extend the projecting superstructure sections. A transport device is movably carried on the auxiliary beam and supports the concreting scaffolds for transport between superstructure sections and from the end of a completed section to a bridge pile for beginning construction of a new section. The supporting part of each of the concreting scaffolds has longitudinal girders arranged adjacent the auxiliary beam and crossbars connected to the girders arranged below the auxiliary beam. A pair of supporting blocks for supporting the auxiliary beam on the next succeeding pile are arranged so as to be alternately retractable to allow the supporting part of the scaffolds to pass the bridge pile, and the platform of the scaffolds comprises a bending resistant lattice of crossbeams and girders with means for forming openings therein to allow the platform to pass the pile as the scaffold is transported to the next section.
