To provide a lifting device of a steel frame capable of carrying out high-work of separating a suspending jig and the steel frame with safe light work and lowering the height of a receiving piece welded to the steel frame, when assembling the steel frame at a site.SOLUTION: A lifting device of a steel frame configures a suspending jig TJ with a suspending piece 2 which includes a fitting groove KM fitted to a receiving piece 1, a doubling plate 4 for supporting one face of the suspending piece 2, a fixing plate 5 fitted into the suspending piece 2 from an upward direction within a fixed fitting groove KM 6B opened extending upward from a lower part, a pressing plate 3A for supporting the other face of the suspending piece 2, a bolt B inserted into a hole opened at the doubling plate 4, the suspending piece 2, and the pressing plate 3A, and a nut B for fastening in a state where the bolt B is inserted. The nut N is fastened after coupling the receiving piece 1 welded to a steel frame G and the suspending piece 2 of the suspending jig TJ to fix the receiving piece 1 and the suspending jig TJ.SELECTED DRAWING: Figure 1
【課題】現場で鉄骨組立ての時、吊り治具と鉄骨の切り離しを高所作業でも安全な軽作業で行なえ且つ鉄骨に溶接する受けピースの高さを低く押さえる鉄骨の揚重装置の提供。【解決手段】受けピース１と嵌合し合う嵌合溝ＫＭを備えた吊りピース２と、吊りピース２の一方の面を支承するための添え板４と、その下部から上方に延びて開設された固定用嵌合溝６Ｂ内に上方向から吊りピース２と嵌合する固定板５と、吊りピース２の他方の面を支承するための押さえ板３Ａと、添え板４、吊りピース２及び押さえ板３Ａに開設した孔内に挿通するボルトＢ及びボルトＢが挿通した状態で締め付けするためのナットＮとで吊り治具ＴＪを構成し、鉄骨Ｇに溶接された受けピース１と吊り治具ＴＪの吊りピース２とを連結した後にナットＮを締め付けて、受けピース１と吊り治具ＴＪとを固定する。【選択図】図１
