PROBLEM TO BE SOLVED: To provide a steel pipe pile joint structure including a fixing mechanism having a structure that is attachable/detachable to and from it.SOLUTION: This invention relates to a steel pipe pile coupler structure for use in connecting a lower steel pipe pile 2 initially installed at a foundation with an upper steel pipe pile 4 connected to an upper end of the lower steel pipe pile 2. A fixing means 10 for fixing the lower steel pipe pile 2 and the upper steel pipe pile 4 is constituted by a lock hole 9 having truncated-cone shape communicating between the upper steel pipe pile 4 and the lower steel pipe pile 2; a tapered lock part 11 of truncated-cone shape corresponding to the lock hole; a fixing washer part 12 abutted against the tapered lock part; a fastening washer part 13 fitted into the fixing washer part; a fixing bolt part 14 arranged to pass through the fastening washer part, the fixing washer part and the tapered lock part; a nut part 15 arranged at a large diameter end of outside part of the pile of the tapered lock part to cause the fixing bolt part to be engaged in thread with it to fasten the fixing bolt part; and an anti-looseness washer part 16.SELECTED DRAWING: Figure 4
【課題】着脱可能な構造を有する固定機構を具備する鋼管杭継手構造を提供する。【解決手段】地盤に最初に設置される下側鋼管杭2と、この下側鋼管杭2の上端に連結される上側鋼管杭4とを結合するための鋼管杭継手構造において、下側鋼管杭2と上側鋼管杭4を固定する固定手段10が、上側鋼管杭4と下側鋼管杭2を連通する円錐台形状のロック穴9と、該ロック穴に対応した円錐台形状のテーパロック部11と、該テーパロック部に当接する固定ワッシャ部12と、該固定ワッシャ部に嵌まり込む締め込みワッシャ部13と、前記締め込みワッシャ部、前記固定ワッシャ部及び前記テーパロック部を貫通して配置される固定用ボルト部14と、前記テーパロック部の杭外側の大径端に配置され、前記固定用ボルト部が螺合して前記固定用ボルト部を締め付けるナット部15と、ゆるみ止めワッシャ部16とによって構成される。【選択図】図4
