STANDARD FRAME FOR SCAFFOLDING

摘要

PROBLEM TO BE SOLVED: To provide a standard frame reducing labor of release of lock metal fittings by half when a handrail frame is removed from the standard frame for a scaffolding used at a construction site or the like. SOLUTION: The standard frame for the scaffolding constituted by providing a plurality of lock metal fittings for mounting the handrail or bracings is so formed that one of the lock metal fittings making a pair to vertical columns 51 and 52 forming the standard frame is used for a movable lock metal fitting 24 and that the other is used for a fixed lock metal fitting 23. For the standard frames, a shrine-entrance type standard frame and an H-frame are typical ones. COPYRIGHT: (C)2005,JPO&NCIPI
