JOINT STRUCTURE OF STEEL PIPE PILE AND CONNECTION STEEL PIPE PILE
PROBLEM TO BE SOLVED: To provide a joint structure of a steel pipe pile and a connection steel pipe pile, with which establishment operation of a plurality of steel pipe piles may be efficiently carried out while improving economical property as a mechanical joint.SOLUTION: A joint structure 7 of a steel pipe pile to which the present invention is applied is for connecting a plurality of steel pipe piles 2 in shaft core direction Y, which comprises a pair of outer end part 3 and inner end part 5 which are fitted one another. The outer end part 3 comprises an outer hill part 31 formed by inwardly projecting in shaft core orthogonal direction X and an outer valley part 33 formed at base end side B by the outer hill part 31. The inner end part 5 comprises an inner hill part 51 formed by outwardly projecting in the shaft core orthogonal direction X and an inner valley part 53 formed at the base end side B by the inner hill part 51. On the outer valley part 33, an outer step part 4 having a plurality of steps from tip side A to the base end side B. On the inner valley part 53, an inner step part 6 having one or more steps from the tip side A to the base end side B is arranged. The number of steps of the inner step part 6 is less than the number of steps of the outer step part 4.SELECTED DRAWING: Figure 9
【課題】機械式継手としての経済性を向上させながら、複数の鋼管杭の打設作業を効率的に実施することのできる鋼管杭の継手構造及び連結鋼管杭を提供する。【解決手段】本発明を適用した鋼管杭の継手構造７は、複数の鋼管杭２を軸芯方向Ｙに連結させるためのものであり、互いに嵌合自在な一対の外嵌端部３と内嵌端部５とを備える。外嵌端部３は、軸芯直交方向Ｘで内側に突出させて形成された外嵌山部３１と、外嵌山部３１より基端側Ｂに形成された外嵌谷部３３とを有し、内嵌端部５は、軸芯直交方向Ｘで外側に突出させて形成された内嵌山部５１と、内嵌山部５１より基端側Ｂに形成された内嵌谷部５３とを有する。外嵌谷部３３は、先端側Ａから基端側Ｂまで複数の段数の外嵌段部４が設けられる。内嵌谷部５３は、先端側Ａから基端側Ｂまで１又は複数の段数の内嵌段部６が設けられて、外嵌段部４の段数よりも内嵌段部６の段数を少ないものとする。【選択図】図９
