FLOOR SLAB ERECTION METHOD AND FLOOR SLAB ERECTION DEVICE
PROBLEM TO BE SOLVED: To provide a floor slab erection method and floor slab erection device capable of reducing a work space in the road width direction.SOLUTION: A precast floor slab 4 is faced so that the longer direction of the precast floor slab 4 runs along the bridge axial direction, and suspended from a device body 10 to be moveable in the bridge axial direction. Therefore, the width of the device body 10 can be made smaller than half the width of a road width. In this case, the precast floor slab 4 raised by a first suspension mechanism 14 can be moved in the bridge axial direction in pendulum form by a second suspension mechanism 15, allowing the precast floor slab 4 to be longitudinally moved to an installation position by its own weight. Therefore, hoisting movement to a prescribed construction position (a position extending forwards) for the precast floor slab 4 is possible in the longitudinal direction, while also allowing a simplified and light-weight structure without the necessity of using an engine-driven type movement mechanism.SELECTED DRAWING: Figure 19
【課題】道路幅方向の作業スペースを小さくすることのできる床版架設方法及び床版架設装置を提供する。【解決手段】プレキャスト床版４をプレキャスト床版４の長手方向が橋軸方向となる向きで装置本体１０から吊り下げて橋軸方向に移動させるようにしているので、装置本体１０の幅を道路幅員の半幅よりも小さくすることができる。この場合、第１の吊り下げ機構１４によって上昇させたプレキャスト床版４を第２の吊り下げ機構１５によって振り子状に橋軸方向に移動させることにより、プレキャスト床版４を自重で設置位置に縦移動させるようにしたため、プレキャスト床版４の所定架設位置（前方に延出する位置）までの縦方向への吊り上げ移動が可能になり、機械駆動式の移動機構を用いる必要がなく、構造の簡素化及び軽量化を図ることができる。【選択図】図１９
