PILE HEAD SEISMIC ISOLATION STRUCTURE
To provide a pile head seismic isolation structure capable of compactly realizing a strong skeleton.SOLUTION: A pile head seismic isolation structure 20A in which a seismic isolation device 4 is installed on a pile head 21t of a foundation pile 21 comprises a prefabricated concrete foundation pile 21, a foundation reinforced concrete portion 23A in which the pile head 21t of the foundation pile 21 is covered and the seismic isolation device 4 is installed, and a pile head reinforcing material 30 embedded in the foundation reinforced concrete portion 23A. The pile head reinforcing material 30 has a plurality of vertical reinforcing bars 31 each formed in an U-shape and provided radially with respect to a hollow portion 21h provided in the center of a cross section of the foundation pile 21, and an annular horizontal reinforcing bar 32 bound to vertical reinforcing bar 31. One material end 31s of each of the plurality of vertical reinforcing bars 31 is embedded in a concrete body 24 filled in the hollow portion 21h of the foundation pile 21, and the other material end 31t is embedded in the foundation reinforced concrete portion 23.SELECTED DRAWING: Figure 1
【課題】強固な躯体をコンパクトに実現可能な杭頭免震構造を提供する。【解決手段】基礎杭２１の杭頭部２１ｔに免震装置４が設置される杭頭免震構造２０Ａであって、既製コンクリート造の基礎杭２１と、基礎杭２１の杭頭部２１ｔを覆い、免震装置４が設置される基礎鉄筋コンクリート部２３Ａと、基礎鉄筋コンクリート部２３Ａに埋設される杭頭補強材３０と、を備え、杭頭補強材３０は、各々がＵ字形状に形成され、基礎杭２１の横断面中央に設けられる中空部２１ｈに対して、放射状に設けられる複数の縦補強筋３１と、縦補強筋３１に結束される円環状をなす横補強筋３２と、を有し、複数の縦補強筋３１の各々の一方材端３１ｓは、基礎杭２１の中空部２１ｈに充填されたコンクリート体２４に埋設され、他方材端３１ｔが基礎鉄筋コンクリート部２３に埋設されている。【選択図】図１
