To provide a steel frame lifting device allowing high place work for separation of a suspension tool and a steel frame to be carried out as safer light work upon assembling steel frames at the site as well as allowing its assembly to be easily carried out through a minimized number of parts for reduced weight, and allowing joint between a receiving piece fixed on the steel frame and the suspension tool to be securely and easily carried out.SOLUTION: A suspension tool TJ comprises: a suspension piece 2, a limiting plate 4, a pair of stationary plates 6, 6, a slip-off prevention bolt 3B, and a nut 3N. When the bolt 3B is inserted into a long hole 7 of the stationary plates 6, 6 to be positioned at an upper position, the bolt 3B is not allowed to obstruct this fitting when a receiving piece 1 is fitted into a fitting groove KM of the suspension piece 2, as well as when the bolt 3B is positioned at a lower position in the long hole 7, the receiving piece 1 in a state of fitting in the fitting groove KM of the suspension piece 2 from an opposite side to a face on which the limiting plate 4 is fixed fastens the nut 3N so as to be prevented from slipping out of the fitting groove KM with the bolt 3B.SELECTED DRAWING: Figure 13
【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より安全な軽作業で行なえ、且つ部品点数を極力減少させて軽量として製作も容易で、前記鉄骨に固定された受けピースと前記吊り治具との連結を確実且つ容易に行える鉄骨の揚重装置の提供。【解決手段】吊り治具ＴＪを吊りピース２、規制板４、一対の固定板６、６、抜け防止用ボルト３Ｂ及びナット３Ｎから構成し、前記ボルト３Ｂが両固定板６、６の長孔７に挿通して上方位置にあるときには吊りピース２の嵌合溝ＫＭに受けピース１が嵌合するときにその嵌合を前記ボルト３Ｂが邪魔することがないようにし、前記ボルト３Ｂが長孔７内の下方位置にあるときには規制板４が固定された面とは反対側から吊りピース２の嵌合溝ＫＭに嵌合した状態の受けピース１がナット３Ｎを締めることにより前記ボルト３Ｂにより嵌合溝ＫＭから外れないようにした。【選択図】図１３
