PILE HEAD BASE ISOLATION JOINT STRUCTURE
PROBLEM TO BE SOLVED: To provide a pile head base isolation joint structure in which variations in resistance force depending on directions of horizontal shearing force are suppressed and workability is improved.SOLUTION: A pile head base isolation joint structure includes a base isolator 5 for performing base isolation support of a skeleton, the base isolator being fitted on a concrete pedestal 2 made from concrete filled between a pile head 1a of a foundation pile 1 having an outer peripheral side part made of a steel pipe and an outer cylindrical body 3 encircling the outer peripheral side of the pile head 1a, via a base plate 6 provided across a top end of the cylindrical body 3 and a top face of the concrete pedestal 2. In the concrete pedestal 2 is embedded a bearing pressure ring 14 in a state in which the ring is joined to an outer peripheral face of the pile head 1a, the ring extending continuously or intermittently in the circumferential direction, where the ring's vertical dimension of its inner peripheral face jointed to the pile head is larger than its width dimension in a horizontal direction.SELECTED DRAWING: Figure 1
【課題】杭頭免震接合構造において、水平剪断力の方向による抵抗力のばらつきを抑制し、かつ施工性を向上させる。【解決手段】外周部が鋼管からなる基礎杭１の杭頭１ａと、杭頭１ａの外周側を包囲する外筒体３との間に充填されたコンクリートからなるコンクリート台座２上に、外筒体３の上端及びコンクリート台座２の上面に跨って設置されたベースプレート６を介して、躯体を免震支持する免震装置５を取り付けてなる杭頭免震接合構造において、コンクリート台座２に、周方向へ連続又は断続して延び、水平方向の幅寸法よりも杭頭と接合された内周面における鉛直方向の寸法が大きい支圧リング１４が、杭頭１ａの外周面に接合された状態で埋設されている。【選択図】図１
