PROBLEM TO BE SOLVED: To provide a steel pipe connection joint that is hard to uncouple without extending a thread part length when a tension load is applied.SOLUTION: A connection joint 1 for a steel pipe according to this invention is a steel pipe connection joint that is fit on an end of a steel pipe 3 constituting a structure to be installed underground and connects the steel pipes 3 with each other. The connection joint comprises: a male side cylindrical body 5, which has a male screw that is parallel screw and made from multiple thread and has a junction with the steel pipe 3 at one end; and female side cylindrical body 7, which has a female screw that is parallel screw and made from multiple thread and has a junction with the steel pipe 3 at one end. In a state where the male side cylindrical body 5 and the female side cylindrical body 7 are connected, centers of the male screw and the female screw are matched with the center of the junction in plate thickness direction.SELECTED DRAWING: Figure 1
【課題】ねじ部の長さを長くしなくても引張り荷重が作用した際に外れにくい鋼管の接合継手を提供する。【解決手段】本発明に係る鋼管の接合継手１は、地中に打設する構造体を構成する鋼管３の端部に取り付けられて鋼管３同士を接合する鋼管の接合継手であって、平行ねじで多条ねじからなる雄ねじを有すると共に一端側が鋼管３との接合部となっている雄側筒体５と、平行ねじで多条ねじからなる雌ねじを有すると共に一端側が鋼管３との接合部となっている雌側筒体７とを有し、雄側筒体５と雌側筒体７を接合した状態で、雄ねじと雌ねじの中心と接合部の板厚方向の中心とが一致するように構成されている。【選択図】 図１
