PILE HEAD BASE-ISOLATION STRUCTURE AND CONSTRUCTION METHOD THEREFOR
To provide a pile head base-isolation structure for realizing a strong and compact skeleton.SOLUTION: A pile head base-isolation structure 20A has a seismic isolator 4 at the pile head part 21t of a foundation pile 21, and has the existing concrete foundation pile 21, a foundation reinforced concrete part 23A covering the pile head part 21t of the foundation pile 21 and installed with the seismic isolator 4, and pile head reinforcements 30 embedded in the foundation reinforced concrete part 23A. Each of the pile head reinforcements 30 is formed into a U-shape, and has multiple vertical reinforcements 31 radially arranged in relation to hollow part 21h provided in a sectional center of the foundation pile 21, and annular lateral reinforcements 32 bound to the vertical reinforcements 31. Each of one side material ends 31s of the multiple vertical reinforcements 31 is embedded in a concrete body 24 filled in the hollow part 21h of the foundation pile 21, and each of the other material ends 31t is embedded in the foundation reinforced concrete part 23 A.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
