CONNECTING STRUCTURE OF STEEL PIPE
To provide a connecting structure of a steel pipe which can suppress the loosening of a screw point.SOLUTION: A connecting structure of a steel pipe comprises a first connecting part 20a, a second connecting part 20b, and a joint part 3. The first connecting part 20a has a first male screw part 21a provided at an outer surface and including a thread in a first winding direction L, and a first female screw part 22a provided at an inner surface and including a thread in a second winding direction R. The second connecting part 20b has a second male screw part 21b provided at an outer surface and including a thread in the first winding direction L, and a tip part 20c integrally provided at a portion at which the second male screw part 21b is provided. The tip part 20c has a tip male screw part 22c provided at an outer surface, including a thread in the second winding direction R, and screwed with the first form screw part 22a. The joint part 3 has a joint female screw part 31 provided at an inner surface, including a thread in the first winding direction L, and screwed with the first male screw part 21a and the second male screw part 21b.SELECTED DRAWING: Figure 1
【課題】螺合箇所の緩みを抑制できる鋼管の接続構造を提供する。【解決手段】第１接続部２０ａと、第２接続部２０ｂと、継手部３とを備え、第１接続部２０ａは、外表面に設けられ、第１巻き方向Ｌのねじ山を含む第１雄ねじ部２１ａと、内表面に設けられ、第２巻き方向Ｒのねじ山を含む第１雌ねじ部２２ａとを有し、第２接続部２０ｂは、外表面に設けられ、第１巻き方向Ｌのねじ山を含む第２雄ねじ部２１ｂと、第２雄ねじ部２１ｂの設けられた部分と一体に設けられた先端部２０ｃとを有し、先端部２０ｃは、外表面に設けられ、第２巻き方向Ｒのねじ山を含み、第１雌ねじ部２２ａと螺合するものである先端雄ねじ部２２ｃを有し、継手部３は、内表面に設けられ、第１巻き方向Ｌのねじ山を含み、第１雄ねじ部２１ａ及び第２雄ねじ部２１ｂと螺合するものである継手雌ねじ部３１を有することを特徴とする。【選択図】図１
