EXTENDED PILE HEAD ISOLATION STRUCTURE
PROBLEM TO BE SOLVED: To provide an extended pile head isolation structure that eliminates the need for a conventional pile head capital, and thereby simplifies a basal structure of an isolation pit.SOLUTION: A pile head isolation structure of the present invention is configured such that multiple piles 1 are formed in a bottom of an isolation pit P as a base isolation foundation, and an isolation device 2 is installed on a pile head 10 of each pile 1, and thereby a structure B is adapted to support base isolation through the isolation device 2 on each pile head 10. With this structure, particularly, each pile 1 comprises an extended head pile forming an extended head part 11 by making the pile head 10 larger than the diameter of the pile 1 and making a top end 100 be substantially the same as an installation area of the isolation device 2 or greatly increased in diameter more than that, and each extended head part 11 is disposed in the bottom of the isolation pit P. Each isolation device 2 is installed on the top end 110 of each extended head part 11.SELECTED DRAWING: Figure 1
【課題】従来の杭頭キャピタルを不要とし、免震ピットの底部の構造を簡略化する。【解決手段】この杭頭免震構造は、免震ピットＰの底部に免震基礎として複数の杭１が形成され、各杭１の杭頭部１０上に免震装置２が設置されて、構造物Ｂを各杭頭部１０上に免震装置２を介して免震支持するようになっている。この構造では、特に、各杭１は杭頭部１０を杭１の径よりも大きく天端１００を免震装置２の設置面積と略同じかそれよりも大きく拡径されて拡頭部１１となす拡頭杭からなり、各拡頭部１１が免震ピットＰの底部に配置される。各免震装置２は各拡頭部１１の天端１１０上に設置される。【選択図】図１
