TEMPORARY SCAFFOLDING FOR CONSTRUCTION OF LARGE BUILDING AND CONSTRUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To perform construction correctly with simple structure, sufficient rigidity and sufficient safety of various works in the installation and removal work of a temporary scaffolding for construction provided at an under-girder part of a bridge beam. ;SOLUTION: At the time of pin-connecting unit frames 15, 15 of plural sizes to joints 19, 19', 19" so as to coincide with the span of bents or piers 13, 13 in order to batch-construct a temporary scaffolding 12' of beam integrated structure edge-cut into separate structure from a bridge beam between the bents or piers 13, 13, side frames 17 are made a folding type freely opened/ closed through hinges 24 in relation to upper frames. In the folded state, the upper frames and the side frames 17 are thereby placed in the flat state and piled in layers compactly on a truck so as to be smoothly carried in and out and moreover can be set with sufficient rigidity.;COPYRIGHT: (C)1997,JPO
