STEEL PIPE JOINT

To provide a steel pipe joint in which the increase in a manufacturing cost is suppressed and which does not largely protrude to the outer periphery.SOLUTION: A steel pipe joint 1 comprises: a plurality of sheath pipe side plug insertion holes 13 which are provided along the peripheral direction of a sheath pipe 12; a plurality of insertion pipe side plug insertion holes 23 which are provided in an insertion pipe 22 and arranged corresponding to the sheath pipe side plug insertion holes 13; and a plurality of plug receivers 45 which are provided on an inner peripheral surface 25 of the insertion pipe 22 and receive plugs 31 inserted into the sheath pipe side plug insertion holes 13 and the insertion pipe side plug insertion holes 23. The steel pipe joint is formed by screwing and fastening a bolt 7 inserted into a bolt insertion hole of each plug 31 to a screw hole of the plug receiver 45 and fastening the plug 31 to the plug receiver 45. Therefore, processing accuracy of the sheath pipe side plug insertion holes 13 and the insertion pipe side plug insertion holes 23 can be easily secured, and the increase in a manufacturing cost of the steel pipe joint 1 in which the increase in a cost is suppressed and which does not largely protrude to the outer periphery and a structure using the steel pipe joint 1 can be suppressed.SELECTED DRAWING: Figure 2 【課題】製造コストの増大を抑制した外周に大きく張り出すことのない鋼管継手を提供する。【解決手段】鞘管１２の周方向に沿って設けられる複数個の鞘管側プラグ挿入孔１３と、挿入管２２に設けられて鞘管側プラグ挿入孔１３に対応して配置される複数個の挿入管側プラグ挿入孔２３と、挿入管２２の内周面２５に設けられて鞘管側プラグ挿入孔１３、挿入管側プラグ挿入孔２３に挿入されたプラグ３１を受ける複数個のプラグ受４５とを備え、各プラグ３１のボルト挿通孔に挿通させたボルト７をプラグ受４５のねじ孔に螺合して締め付けることで、プラグ３１をプラグ受４５に締結させることで鋼管継手１を構成したので、鞘管側プラグ挿入孔１３，挿入管側プラグ挿入孔２３の加工精度を容易に確保することが可能であり、コストの増大を抑制した外周に大きく張り出すことのない鋼管継手１、延いては鋼管継手１を用いた構造物の製造コストの増大を抑制することができる。【選択図】図２
