JOINT MEMBER, AND CONNECTION STRUCTURE OF JOINT MEMBER AND STEEL PIPE
To smoothly continue an inner peripheral surface while securing the linearity of steel pipes to be added.SOLUTION: A joint member has a male joint and a female joint for connecting steel pipes adjacent to each other in an axial direction, wherein the male joint and the female joint are composed of cylindrical bodies having outer diameters substantially equal to the steel pipes, a diameter-reduced surface whose outer diameter gradually decreases is formed on the outer surface of the cylindrical body and one end side of the cylindrical body is reduced, a steel pipe insertion part is provided on the one diameter-reduced end side, and an inclined surface toward the inner peripheral surface of the steel pipe is formed on the inner peripheral side of the steel pipe insertion part of at least one of the male joint and the female joint.SELECTED DRAWING: Figure 6
【課題】継ぎ足す鋼管どうしの直線性を確保しつつ、内周面を滑らかに連続させることである。【解決手段】軸線方向に隣り合う鋼管どうしを連結するオス継手及びメス継手を備える継手部材であって、オス継手及びメス継手はそれぞれ、鋼管と略等しい外径を有する筒状体よりなり、筒状体は、外周面に外径を漸次縮径する縮径面が形成されて一端側が縮径されるとともに、縮径された一端側に鋼管挿入部が設けられ、オス継手及びメス継手のうち、少なくともいずれか一方の鋼管挿入部の内周側に、鋼管の内周面に向かう斜面が形成されている。【選択図】図６
