SUSPENDED SCAFFOLD DEVICE
To provide a suspended scaffold device which does not require a rail for suspending a scaffold to be separately attached to a bridge side, and also can be moved to the opposite side of the bridge pier even in the bridge having the bridge pier whose width is wider than its superstructure.SOLUTION: While a first scaffold part 10 in which a suspension member 40 is engaged with a main girder 1 is left on an end side in a bridge axial direction of a bridge pier 3, the suspension member 40 of a second scaffold part 20 and the main girder 1 are disengaged, and also the second scaffold part 20 is moved to the other end side in the bridge axial direction of the bridge pier 3 through the lateral side of the bridge pier 3. After the suspension member 40 of the second scaffold part 20 which is moved to the other end side in the bridge axial direction of the bridge pier 3 is then engaged with the main girder 1, the suspension member 40 of a first scaffold part 10 on an end side in the bridge axial direction and the main girder 1 are disengaged, and the first scaffold part 10 on an end side in the bridge axial direction is moved to the other end side in the bridge axial direction of the bridge pier 3 through the lateral side of the bridge pier 3. Therefore, as in a conventional manner, it is not necessary to separately attach a member for suspending a scaffold to the bridge side, which allows the use in a bridge having a bridge pier whose width is wider than its superstructure.SELECTED DRAWING: Figure 9
【課題】足場を吊り下げるためのレールを橋梁側に別途取り付ける必要がなく、橋脚が上部工よりも幅広の橋梁においても橋脚の反対側へ移動することのできる吊り足場装置を提供する。【解決手段】吊下部材４０が主桁１と係合している第１の足場部１０を橋脚３の橋軸方向一端側に残した状態で、第２の足場部２０の吊下部材４０と主桁１との係合を解除するとともに、第２の足場部２０を橋脚３の側方を介して橋脚３の橋軸方向他端側に移動させ、橋脚３の橋軸方向他端側に移動した第２の足場部２０の吊下部材４０を主桁１に係合させた後、橋軸方向一端側の第１の足場部１０の吊下部材４０と主桁１との係合を解除し、橋軸方向一端側の第１の足場部１０を橋脚３の側方を介して橋脚３の橋軸方向他端側に移動させるようにしたので、従来のように足場吊り下げ用の部材を橋梁側に別途取り付ける必要がなく、橋脚が上部工より幅広の橋梁にも用いることができる。【選択図】図９
