Constrcution method of end cross beam for integrating continuity of supporting portion and preventing falling down of psc girder

PURPOSE: A continuous construction method of an end floor beam for prevention of falling of a PSC(PreStressed Concrete) girder and continuation of a support unit is provided to prevent falling of the PSC girder in installation of the PSC girder and to enable a worker to conveniently construct the end floor beam by not needing removal work of a mold. CONSTITUTION: A continuous construction method of an end floor beam for prevention of falling of a PSC girder(10) and continuation of a support unit comprises a step of manufacturing a plurality of PSC girders including a preventing falling block(12) in an end; a step of supporting the PSC girders to each support unit of bridge legs of a bridge side by side; a step of installing a cross reinforcing bar at a hole(10c) formed in the end of the PSC girder; a step of installing a mold unit in order to obtain concrete placing space of the end floor beam by comparting a bottom surface and a side wall at the end of the PSC girder and the preventing falling block ; and a step of constructing the end floor beam crossing the end of the PSC girder by placing concrete at the concrete placing space of the end floor beam.
