STEEL PIPE CONCRETE PILE JUNCTION STRUCTURE
PROBLEM TO BE SOLVED: To provide a steel pipe concrete pile junction structure capable of reducing manufacturing cost.SOLUTION: A steel pipe concrete pile junction structure is a structure of a junction between a steel pipe concrete pile 10 and a foundation 20. The steel pipe concrete pile 10 comprises a cylindrical steel pipe 11, a concrete body 12 installed inside of the steel pipe 11, an annular back plate 30 set on an upper edge of the steel pipe 11, a pile head connecting reinforcement 40 that is connected to a top face of the back plate 30 and fixed on the foundation 20, and an anchor reinforcement 41 that is connected to an undersurface of the back plate 30 and fixed to the concrete body 12. The back plate 30 comprises a steel pipe joint part 30A that is connected to an upper edge of the steel pipe 11 and has an engaging part inside the steel pipe and a reinforcement joint part 30B to which the pile head connecting reinforcement 40 and the anchor reinforcement 41 are connected. A thin wall part 32 is placed between the steel pipe joint part 30A and the reinforcement joint part 30B of the back plate 30.
【課題】製作コストを低減できる鋼管コンクリート杭の接合構造を提供すること。【解決手段】鋼管コンクリート杭接合構造は、鋼管コンクリート杭１０と基礎２０との接合部の構造である。鋼管コンクリート杭１０は、筒状の鋼管１１と、この鋼管１１の内部に打設されたコンクリート体１２と、鋼管１１の上端縁に設けられた環状の座板３０と、この座板３０の上面に接合されて基礎２０に定着する杭頭結合鉄筋４０と、座板３０の下面に接合されてコンクリート体１２に定着するアンカー鉄筋４１と、を備える。座板３０は、鋼管１１の上端縁に接合されて当該鋼管の内部側に係合部を有する鋼管接合部３０Ａと、杭頭結合鉄筋４０およびアンカー鉄筋４１が接合される鉄筋接合部３０Ｂと、を有する。座板３０の鋼管接合部３０Ａと鉄筋接合部３０Ｂとの間に、薄肉部３２が設けられる。【選択図】図３
