BASE ISOLATION UPPER FOUNDATION STRUCTURE AND MANUFACTURING METHOD OF THE SAME
To provide a base isolation upper foundation structure manufactured from precast concrete.SOLUTION: A manufacturing method of a base isolation upper foundation structure comprises: disposing, in a formwork in which an inside formwork is provided in a floating state from a bottom plate inside a side plate in an outside formwork including the bottom plate with through holes and the side plate standing straight from the bottom plate, a bag-shaped nut with an anchor plate at its upper portion corresponding to disposition of the through holes of the bottom plate; arranging a base reinforcement inside the outside formwork; and forming a flat plate portion where an upper portion of the bag-shaped nut is exposed and a standing portion surrounding the flat plate portion by placing concrete at a height reaching a lower end of the inside formwork inside the outside formwork and placing concrete between the outside formwork and the inside formwork.SELECTED DRAWING: Figure 1
【課題】プレキャストコンクリートで作製された免震上部基礎構造を提供することを目的の一つとする。【解決手段】貫通孔が形成された底板と、底板に対して直立する側板とを含む外側型枠に、側板の内側に底板から浮いた状態で内側型枠が設けられた型枠に、底板の貫通孔の配置に合わせて、上部に定着板が付された袋状ナットを配置し、外側型枠の内側に、ベース筋を配筋し、外側型枠の内側に、内側型枠の下端に達する高さにコンクリートを打設し、及び外側型枠と内側型枠との間にコンクリートを打設することで、袋状ナットの上部が露出する平板部と、平板部を囲む立ち上がり部と、を形成すること、を含む。【選択図】図１
