Suspension scaffold construction method and suspension scaffold in bridge structure

摘要

A scaffold can be installed on a bridge structure without descending under the bridge. A hoist side first wire HW1 is bridged between a first side surface 6 and a second side surface 7 which are one side surfaces of a bridge girder 1 in the width direction, and a suspension scaffold 100 is provided. The process of suspending the suspension scaffold 100 with the crane CN from the upper side on the second side surface 7 side in a posture in which the first scaffold suspension position FP1 side is lower than the second scaffold suspension position FP2 side, The suspension scaffold 100 is rotated so that the height difference between the first scaffold suspension position FP1 and the second scaffold suspension position FP2 is reduced while the suspension scaffold 100 is lowered from the upper side to the lower side. The hoist side first wire HW1 and the hoist side second wire HW2 are wound up by the first hoist HT1 and the second hoist HT2 to move the suspension scaffold 100 to the bottom surface of the bridge structure. And the process of fixing to Including. [Selection] Figure 17
