ROTATION SUPPRESSING STRUCTURE OF STEEL PIPE PILE
PROBLEM TO BE SOLVED: To provide a rotation suppression structure of a steel pipe pile capable of ensuring the connection state of a first steel pipe pile with a second steel pipe pile by improving the rotational resistance between an outer fitting end part and an inner fitting end part.SOLUTION: The invention relates to a rotation suppression structure 7 of a steel pipe pile suppressing the relative rotation of a first steel pipe pile 1 with a second steel pipe pile 2. The rotation suppression structure 7 of the steel pipe pile to which the invention is applied includes: an outer fitting end part 3 linking the first steel pipe pile 1 with the second steel pipe pile 2; and an inner fitting end part 5. The outer fitting end part 3 has an outer fitting crest part 31, an outer fitting groove part 32, an outer fitting trough 33, an outer fitting tip part 34 and an outer fitting base end part 35. The inner fitting end part 5 includes an inner fitting crest part 51, an inner fitting groove part 52, an inner fitting trough 53, an inner fitting tip part 54 and an inner fitting base end part 55. A protrusion part 71 is formed in the outer fitting tip 34 and the inner fitting tip 54. A groove part 72 is formed in the outer fitting base end part 35 and the inner fitting base end part 55. The protrusion part 71 is engaged with the groove part 72 by relatively rotating the outer fitting end part 3 and the inner fitting end part 5 in a circumferential direction W while being inserted into the groove part 72.
【課題】外嵌端部と内嵌端部との回転抵抗力を向上させて、第１鋼管杭と第２鋼管杭との連接状態を確実にす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、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、外嵌基端部３５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、内嵌先端部５４と、内嵌基端部５５とを有する。外嵌先端部３４、内嵌先端部５４は、突起部７１が形成される。外嵌基端部３５、内嵌基端部５５は、溝部７２が形成される。突起部７１は、溝部７２に挿入された状態で、外嵌端部３と内嵌端部５とを周方向Ｗに相対回転させることで、溝部７２に係止される。【選択図】図１
