摘要：This invention relates to an arrangement for projecting cantilever sections ofmulti-sectional bridge supporting structures of steel or prestressed concrete formingthe superstructure of the bridge which is supported on bridge piles. The arrangementincludes at least one traveling auxiliary beam movably carried on and arranged above thesuperstructure for spanning between superstructure sections. Two concreting scaffoldseach comprising a supporting part having crossbeams and rollers are arranged above thesuperstructure and carry a platform which is arranged below the superstructure forcarrying casings to extend the projecting superstructure sections. A transport device ismovably carried on the auxiliary beam and supports the concreting scaffolds for
transport between superstructure sections and from the end of a completed section to abridge pile for beginning construction of a new section. The supporting part of each ofthe concreting scaffolds has longitudinal girders arranged adjacent the auxiliary beamand crossbars connected to the girders arranged below the auxiliary beam. A pair ofsupporting 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 scaffoldsto pass the bridge pile, and the platform of the scaffolds comprises a bending resistantlattice of crossbeams and girders with means for forming openings therein to allow theplatform to pass the pile as the scaffold is transported to the next section.
