To provide a pile steel pipe joint structure capable of eliminating welding work in a pile construction site and easily securing strength of a joint portion, not by a bolt joint structure.SOLUTION: Upper and lower pile steel pipes 2 comprise a pile steel pipe body 3 and a disc joint structure portion 4. The disc joint structure portion 4 comprises a short pipe portion 5 and a disc portion 6 fixed by welding to the other face side of the short pipe portion. The disc portion 6 includes a flange portion 7 forming a peripheral groove 7a, and includes a fan-shaped protrusion formed at a pile steel pipe joint face side of the disc portion. Connection means 14 connecting the upper and lower disc joint structure portions 4, 4' comprises: a split ring 11 including two protrusions 11aa capable of engaging with a peripheral groove of the upper and lower flange portions and having an embodiment surrounding a periphery of the flange portions 7, 7'; and fastening means 12 fastening the split ring 11 from an outer peripheral face side to fix.SELECTED DRAWING: Figure 1
【課題】ボルト接合構造によらずに杭施工現場での溶接作業を不要とするとともに接合部の強度を容易に確保可能な杭鋼管接合構造を提供する。【解決手段】上下の杭鋼管２は杭鋼管本体３と円板接合構造部４とからなる。円板接合構造部４は短管部５と短管部の他面側に溶接固定された円板部６とを備える。円板部６は周溝７ａを形成したフランジ部７を有し、円板部の杭鋼管接合面側に形成された扇形凸部を有する。上下の円板接合構造部４、４’を結合する結合手段１４は、上下のフランジ部の周溝に嵌合可能な２つの凸部１１ａａを有し上下のフランジ部７，７’の周囲を囲む態様の分割リング１１と、分割リング１１を外周面側から締付け固定する締付け手段１２とを備える。【選択図】図１
