To provide a screw joint for a steel pipe pile which is not loosened even when force of reverse rotation is applied thereto.SOLUTION: The screw joint for a steel pipe pile includes a female member having a female screw part, a male member having a male screw part screwed to the female screw part, and a connection member for connecting the female member and the male member rotationally fit by the female screw part and the male screw part. The female member further has a female side connection screw part which has a rotation direction for tightening different from that of the female screw part. The male member further has a male side connection screw part which forms a continuous screw part successively to the female side connection screw part in a state of being rotationally fit to the female member by the female screw part and the male screw part, and has a rotation direction for tightening different from that of the male screw part. The connection member has a connection screw part which is screwed to the continuous screw part and connects the female side connection screw part and the male side connection screw part.SELECTED DRAWING: Figure 1
【課題】逆回転の力が加わっても緩まない鋼管杭用ねじ継手を提供する。【解決手段】雌ねじ部を有する雌部材と、雌ねじ部と螺合する雄ねじ部を有する雄部材と、雌ねじ部及び雄ねじ部により回転嵌合された雌部材及び雄部材間を連接する連接部材とを備え、雌部材は、雌ねじ部とは締め付けの回転方向が異なる雌側連結ねじ部をさらに有し、雄部材は、雌ねじ部及び雄ねじ部により雌部材と回転嵌合させた状態において雌側連結ねじ部と連続して連続ねじ部を形成する、雄ねじ部とは締め付けの回転方向が異なる雄側連結ねじ部をさらに有し、連接部材は、連続ねじ部と螺合し、雌側連結ねじ部及び雄側連結ねじ部間を連接する連接ねじ部を有する鋼管杭用ねじ継手とする。【選択図】図１
