SUSPENDED SCAFFOLD ASSEMBLING METHOD, SUSPENDED SCAFFOLD DISASSEMBLING METHOD, AND MOVABLE SUSPENDING TOOL FOR USE THEREIN

摘要

PROBLEM TO BE SOLVED: To provide a suspended scaffold assembling method and a suspended scaffold disassembling method which bring reduction of a high-altitude workload and reduction of working steps without mounting of additional members to a main girder or working of the same beforehand, and are implemented by requiring minimum traffic regulation if necessary, and to provide a movable suspending tool for use in the methods.;SOLUTION: According to the suspended scaffold assembling method, by rolling the movable suspending tool 20 on a lower flange 1a of the main girder 1 of a bridge 9, a parent child pipe 4 is suspended on a workbench 30 in the vicinity of a pier 9 to assemble a suspended scaffold 40 for one unit, and then the assembled unit is moved and set to another pier 9, followed by repeatedly assembling the suspended scaffold 40 for the following units, on the workbench 30. In this manner only by moving the movable suspending tool 20 on the lower flange 1a of the main girder 1, necessity of preliminary mounting of a rail is dispensed with, and therefore corrosion of the rail by rainwater is eliminated. Further, only by assembling the suspended scaffold 40 for one unit, on the workbench 30 in the vicinity of the pier 9 and moving the assembled unit by means of the movable suspending 20, high-altitude workload on an overhanging location is reduced, and assembling of the suspended scaffold is efficiently carried out in a short period of time. Further, necessity of traffic regulation is drastically reduced.;COPYRIGHT: (C)2005,JPO&NCIPI
