(57) Abstract Objective In steel framed reinforced concrete structure building constructionAs for hanging frame foothold, the place where preferential installation it does the external wall board of PC edition and the like andThe top, preferential withdrawal and part withdrawal of hanging frame foothold, the ri applyAnd so on becomes necessary. Then as for this device, hanging frame foothold material expansion and contraction yesTo solve problems by the fact that it makes talent, after the external wall Itadori attaching completingBe able to dismantle framework foothold, improvement of security and compaction of term of works the constructive industryIt is something which is offered to the boundary. Constitution In order to achieve the above-mentioned purpose, as for this device, the hanging frameThe foothold material in the computer (1) is designated as the forma where the expansion and contraction component (2) is settled,Canonical arm (3), securing pin (5), coming out prevention lock(6), clamp (7) and ring (8) for guard rail, fixed piThe hole (9) for n, it comes out, the hole (10) for prevention lock, for volt/boltThe configuration which consists of the hole (11) and the cartridge head Tip (12,13) markQuasi- with to do, depending upon use place the exchange arm (4) the canonical armChanging into (3), the expansion and contraction possible hanging frame foothold which it makes the configuration which you useIt is material onohan.
