FLOOR SLAB REPLACEMENT METHOD FOR COMPOSITE GIRDER BRIDGE
To provide a floor slab replacement method capable of replacing a floor slab 5 without reinforcing a main girder 4 in a composite girder bridge 1.SOLUTION: A floor slab replacement method includes: a step ST2 of providing a pair of support frames 11 at positions sandwiching a composite girder bridge 1 in a bridge axis direction, bridging a girder 12 between the pair of support frames 11, and providing a lifting device 25 for the girder 12 so as to be movable in the bridge axis direction and a bridge width direction; a step ST3 of cutting a floor slab 5; a step ST4 of moving an intermediate floor slab 31 to the vicinity of the support frames 11 using the lifting device 25; a step ST5 of removing an on-girder floor slab 32 from a main girder 4; a step ST6 of arranging a plurality of precast floor slabs 45 carried in the vicinity of the support frames 11 at prescribed positions using the lifting device 25; and a step ST7 of joining the plurality of precast floor slabs 45 arranged at the prescribed positions to each other and to the main girder.SELECTED DRAWING: Figure 7
【課題】合成桁橋１において、主桁４を補強することなく床版５を取り替えることができる床版取替工法を提供する。【解決手段】床版取替工法は、合成桁橋１を橋軸方向に挟む位置に１対の支持架台１１を設け、１対の支持架台１１間にガーダー１２を架け渡し、ガーダー１２に橋軸方向及び橋幅方向に移動可能に揚重装置２５を設けるステップＳＴ２と、床版５を切断するステップＳＴ３と、中間床版３１を支持架台１１の近傍へ揚重装置２５を用いて移動させるステップＳＴ４と、桁上床版３２を主桁４から除去するステップＳＴ５と、支持架台１１の近傍へ搬入された複数のプレキャスト床版４５を、揚重装置２５を用いて所定の位置へ配置するステップＳＴ６と、所定の位置に配置された複数のプレキャスト床版４５を、互いに結合すると共に、主桁に結合するステップＳＴ７と含む。【選択図】図７
