PROBLEM TO BE SOLVED: To simplify construction work not only for lower floor boards but also for upper floor boards, with regard to a method of building a corrugated steel plate web bridge using corrugated steel plates.;SOLUTION: Suspended timbering 100 for the construction of the lower floor boards is suspended from a pair of corrugated steel plates 16 which constitutes a leading block B (n) where the upper floor boards are not yet constructed, and a pair of corrugated steel plates 16 which constitutes the block B (n + 1) next to the leading block B (n) is installed in advance. Thereafter, the suspended timbering 100 is moved to the corrugated steel plates 16 installed in advance, and under these conditions the lower floor board 14 which constitutes the next block B (n + 1) and the upper floor board 12 which constitutes the leading block B (n) are constructed. The upper floor board 12 is constructed by suspending a plurality of precast ribs 22 between the upper ends of both corrugated steel plates 16 at predetermined intervals in the direction of a bridge axis, then laying a plurality of precast plates 24 on the precast ribs 22, and placing upper floor board concrete 26 while the ribs and the precast plates as forms.;COPYRIGHT: (C)2004,JPO
