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
