図４に、吊り治具１０の使用状態を示す。図４に示すように、吊り治具１０は、横倒し状態に仮置きされた鉄骨柱２０に取り付けられる。吊り治具１０は、鉄骨柱２０が立設されたときに上方になる端部側に取り付けられる。吊り治具１０は、先ず、鉄骨柱２０の梯子取付用の係合具２３が設けられていない箇所に嵌合される。吊り治具１０は、係合片１２の先端が、係合具２３側を向くように、鉄骨柱２０に嵌合される。
次に、吊り治具１０を鉄骨柱２０に固定する。このとき、吊り治具１０を鉄骨柱２０の頂部側へ向けてスライドさせ、吊り治具１０の係合片１２を、鉄骨柱２０の係合具２３の隙間２４に差し込む。このようにして、吊り治具１０が鉄骨柱２０に取付及び固定される。
さらに、吊り治具１０の孔１５にそれぞれねじ部材３０を螺合させ、鉄骨柱２０に向けてねじ部材３０を締め込む。このようにして、吊り治具１０が鉄骨柱２０に確実に固定される。このとき、３本のねじ部材３０を締め込むことにより、このねじ部材３０を介して吊り治具１０が鉄骨柱２０に強固に固定される。
次いで、吊り治具１０と、クレーンのフック掛け４０をロープ１３で接続する。このとき、ロープ１３の先端部が輪状に形成されていると、フック掛け４０の係合部４１に簡単に取り付けることができ好適である。
吊り治具１０とフック掛け４０がロープ１３で接続されたら、フック掛け４０をクレーンのフックに取り付ける。そして、クレーンを作動させ、フック掛け４０を吊り上げる。
フック掛け４０が吊り上げられると、フック掛け４０に接続された吊り治具１０、及び吊り治具１０に接続された鉄骨柱２０が吊り上げられる。吊り治具１０は、鉄骨柱２０の頂部側に配設されているので、鉄骨柱２０は頂部側から吊り上げられ、徐々に立ち上がる。鉄骨柱２０が立設するまで、クレーンでの引き上げを行う。鉄骨柱２０が立設されたら、鉄骨柱２０を固定し、吊り治具１０を撤去する。 FIG. 4 shows the usage state of the hanging jig 10.
