To provide a floor slab removal device capable of significantly reducing the load swing at an end of a hoisted floor slab as compared with using a crane vehicle.SOLUTION: A floor slab removal device comprises: a device body 10 placed on an existing floor slab 1; a suspension part 20 liftably suspending a floor slab end 1b; and a support rail 30 provided on the device body 10 so as to extend above a floor slab end removal position, and supporting the suspension part 20 so as to be movable in a direction perpendicular to a bridge axis. The cut floor slab end 1b is hoisted by the suspension part 20, and the suspension part 20 is moved along the support rail 30 toward the other side in the direction perpendicular to the bridge axis. Since the floor slab end 1b is hoisted down by the suspension part 20 onto the existing floor slab 1 in front of the device body 10, the load swing of the hoisted floor slab end 1b can be significantly reduced compared with using a crane vehicle.SELECTED DRAWING: Figure 8
【課題】クレーン車を用いる場合に比べ、吊り上げた床版端部の荷振れを大幅に低減することのできる床版撤去装置を提供する。【解決手段】既設床版１上に配置される装置本体１０と、床版端部１ｂを昇降可能に吊り下げる吊り下げ部２０と、装置本体１０に床版端部除去位置の上方まで延出するように設けられ、吊り下げ部１０を橋軸直角方向に移動可能に支持する支持レール３０とを備え、切断された床版端部１ｂを吊り下げ部２０によって吊り上げるとともに、吊り下げ部２０を支持レール３０に沿って橋軸直角方向他方に向かって移動し、吊り下げ部２０によって床版端部１ｂを装置本体１０の手前の既設床版１上に吊り降ろすようにしているので、クレーン車を用いる場合に比べ、吊り上げた床版端部１ｂの荷振れを大幅に低減することができる。【選択図】図８
