PILE HEAD BASE ISOLATION JOINT STRUCTURE
PROBLEM TO BE SOLVED: To provide a pile head base isolation joint structure which can reduce construction labor, which is excellent in dynamic performance, and which has sufficient strength.SOLUTION: In a pile head base isolation joint structure, a base-isolating device 5 for base-isolating and supporting a skeleton 7 is joined via a base plate 6 onto a concrete pedestal 2 provided in such a manner as to cover a pile head 1a of a foundation pile 1 having an outer peripheral part made of a steel pipe 12. A bearing implement 13 for transferring vertical stress by an almost horizontal plate surface between itself and the concrete pedestal 2 is attached to an outer peripheral surface of the steel pipe 12 of the pile head 1a.
【課題】施工の手間を削減することができ、しかも力学性能に優れ、十分な耐力を有する杭頭免震接合構造を提供する。【解決手段】外周部が鋼管１２からなる基礎杭１の杭頭１ａを覆うように設けられたコンクリート台座２上に、躯体７を免震支持する免震装置５を、ベースプレート６を介して接合してなる杭頭免震接合構造において、杭頭１ａの鋼管１２の外周面に、コンクリート台座２との間で略水平な板面によって鉛直方向の応力を伝達する支圧治具１３を取り付けたものである。【選択図】図１
