FLOOR SLAB LIFTING JIG AND FLOOR SLAB LIFTING METHOD
To provide a floor slab lifting jig and a floor slab lifting method capable of easily performing work associated with lifting of a floor slab.SOLUTION: The floor slab lifting jig according to one embodiment is a floor slab lifting jig 1 for lifting a floor slab C. The floor slab lifting jig includes: a core rod 10 inserted into a hole C3 formed in the floor slab C and having a first diameter enlarged part 12 having an outer diameter smaller than an inner diameter of the hole C3 formed at a lower end; a diameter enlarged member 20 having a cylindrical part 22 into which the core rod 10 is inserted and a second diameter enlarged part 21 capable of enlarging a diameter at a lower end of the cylindrical part 22; and a hanging member 30 for hanging the diameter enlarged member 20 at a position opposed to an outer surface of the core rod 10, wherein the diameter enlarged member 20 is movable along the core rod 10, and the cylindrical part 22 is caught by the first diameter enlarged part 12 in a state of moving downward with respect to the core rod 10, the second diameter enlarged part 21 is enlarged, and the maximum value of an outer diameter of the enlarged second diameter enlarged part 21 is larger than the inner diameter of the hole C3.SELECTED DRAWING: Figure 12
【課題】床版の吊り上げに伴う作業を容易に行うことができる床版吊り上げ治具及び床版吊り上げ方法を提供する。【解決手段】一実施形態に係る床版吊り上げ治具は、床版Ｃを吊り上げる床版吊り上げ治具１であって、床版Ｃに形成された孔Ｃ３に挿入されると共に下端に孔Ｃ３の内径よりも小さい外径を有する第１拡径部１２が形成された芯棒１０と、芯棒１０が挿通される筒状部２２、及び筒状部２２の下端において拡径可能とされた第２拡径部２１を有する拡径部材２０と、芯棒１０の外面に対向する位置において拡径部材２０を吊り下げる吊り下げ部材３０と、を備え、拡径部材２０は、芯棒１０に沿って移動可能とされており、芯棒１０に対して下方に移動した状態で筒状部２２が第１拡径部１２に引っ掛かると共に第２拡径部２１が拡径し、拡径した第２拡径部２１の外径の最大値が孔Ｃ３の内径よりも大きい。【選択図】図１２
