STEEL PIPE PILE ROTATION SUPPRESSING STRUCTURE
PROBLEM TO BE SOLVED: To provide a steel pipe pile rotation suppressing structure capable of preventing a tensile strength and a compressive strength of the whole joint from decreasing and improving a rotation resistance of a first steel pipe pile and a second steel pipe pile.SOLUTION: A steel pipe pile rotation suppressing structure 7 suppresses a relative rotation of a first steel pipe pile 1 and a second steel pipe pile 2. The steel pipe pile rotation suppressing structure 7 according to this invention comprises an outer fitting end 3 and an inner fitting end 5 which link the first steel pipe pile 1 and the second steel pipe pile 2 in an axial core direction Y. The outer fitting end 3 comprises an outer fitting convexity 31, an outer fitting groove 32, an outer fitting concavity 33, and an outer fitting tip 34. The inner fitting end 5 comprises an inner fitting convexity 51, an inner fitting groove 52, an inner fitting concavity 53, and an inner fitting base end 55. A key groove 72 is formed by cutting out an outer face of the inner fitting base end 55. A key member abuts against lateral faces of the outer fitting convexity 31 and the inner fitting convexity 51. The inner fitting base end 55 is installed by inserting the key member between the outer fitting groove 32 and the inner fitting groove 52 from the key groove 72.SELECTED DRAWING: Figure 21
【課題】継手全体の引張耐力及び圧縮耐力の低下を防止するとともに、第１鋼管杭と第２鋼管杭との回転抵抗力を向上させることのできる鋼管杭の回転抑止構造を提供する。【解決手段】第１鋼管杭１と第２鋼管杭２との相対回転を抑止する鋼管杭の回転抑止構造７に関する。本発明を適用した鋼管杭の回転抑止構造７は、軸芯方向Ｙに第１鋼管杭１と第２鋼管杭２とを連接させる外嵌端部３と内嵌端部５とを備える。外嵌端部３は、外嵌山部３１と、外嵌溝部３２と、外嵌谷部３３と、外嵌先端部３４とを有する。内嵌端部５は、内嵌山部５１と、内嵌溝部５２と、内嵌谷部５３と、内嵌基端部５５とを有する。内嵌基端部５５は、内嵌基端部５５の外面が切り欠かれてキー溝部７２が形成されて、外嵌山部３１の側面及び内嵌山部５１の側面に当接されるキー部材が、キー溝部７２から外嵌溝部３２と内嵌溝部５２との間に挿入されて設置される。【選択図】図２１
