INSTALLATION METHOD FOR HANGING SCAFFOLDING IN BRIDGE STRUCTURE AND HANGING SCAFFOLDING
To enable the installation of a scaffolding on a bridge structure without going under the bridge.SOLUTION: The method comprises the steps of: extending a hoist side first wire HW1 through a bottom surface of a bridge girder 1 between a first side surface 6 which is one side surface in the width direction of a bridge girder 1 and a second side surface 7; hanging down a hanging scaffolding 100 by a crane CN from above the side of the second side surface 7 in the attitude in which the side of a first scaffolding hanging position FP1 is below the side of a second scaffolding hanging position FP2; rotating the hanging scaffolding 100 so that the difference in height between the first scaffolding hanging position FP1 and the second scaffolding hanging position FP2 becomes smaller while the hanging scaffolding 100 is lowered downward from above the side of the second side surface 7 so as to move the hanging scaffolding 100 to be located below the bridge girder 1; and hoisting a hoist side first wire HW1 and a hoist side second wire HW2 by a first hoist HT1 and a second hoist HT2 to fix the hanging scaffolding 100 on the bottom surface of the bridge structure.SELECTED DRAWING: Figure 17
【課題】橋梁の下に降りることなく、橋梁構造物に足場を設置可能とする。【解決手段】橋桁１の幅方向の一方の側面である第一側面６と第二側面７との間に、ホイスト側第一ワイヤＨＷ１を、橋桁１の底面を通して架ける工程と、吊足場１００を、第二側面７側の上方からクレーンＣＮで、第一足場吊設位置ＦＰ１側が第二足場吊設位置ＦＰ２側よりも下となる姿勢で吊り下げる工程と、吊足場１００を、第二側面７側の上方から、下方側に降下させつつ、第一足場吊設位置ＦＰ１と第二足場吊設位置ＦＰ２との高低差が小さくなるように、吊足場１００を回転させて、吊足場１００を橋桁１の下方に位置するように移動させる工程と、第一ホイストＨＴ１及び第二ホイストＨＴ２で、ホイスト側第一ワイヤＨＷ１及びホイスト側第二ワイヤＨＷ２を巻き上げて、吊足場１００を橋梁構造物の底面に固定する工程とを含む。【選択図】図１７
