CONSTRUCTION METHOD FOR BASE-ISOLATED FOUNDATION STRUCTURE, PRECAST CONCRETE FOUNDATION BLOCK, FORMWORK FOR PRECAST CONCRETE, AND MANUFACTURING METHOD FOR FOUNDATION BLOCK
To provide a construction method for based-isolated foundation structures that can reduce the construction period and cost for installing a base isolator.SOLUTION: The construction method for based-isolated foundation structures includes the steps of: installing a foundation 10 with first reinforcements 14; preparing a foundation block 20 that is pre-casted while having receiving portions 28 and nuts 57; inserting first reinforcements 14 into receiving portions 28 and installing the foundation block 20 on the foundation 10 with a gap; introducing a grout material into joint space and receiving portions 28; and installing a base-isolator on a top surface 21. The receiving portion 28 is formed by an embedded sleeve 56 that extends from a bottom surface 24 in a vertical direction D. A through hole 29 that communicates with the receiving portion 28 opens on an outer peripheral surface 26 of the foundation block 20. The grout material fills the receiving portions 28 and the through holes 29.SELECTED DRAWING: Figure 5
【課題】免震装置を設置するための工期を短縮し、かつ、工事費を抑えることができる免震基礎構造の施工方法を提供する。【解決手段】免震基礎構造の施工方法は、第１鉄筋１４を備える基礎１０を打設する工程と、受入部２８とナット５７とを備えるようにプレキャストされた基礎ブロック２０を用意する工程と、第１鉄筋１４を受入部２８に挿入して基礎１０の上に隙間をあけて基礎ブロック２０を設置する工程と、接合空間及び受入部２８にグラウト材を注入する工程と、上面２１に免震装置を設置する工程と、を含む。受入部２８は、底面２４から鉛直方向Ｄに延びる埋設スリーブ５６によって形成される。基礎ブロック２０の外周面２６には、受入部２８に連通する連通孔２９が開口する。グラウト材は、受入部２８及び連通孔２９に充填される。【選択図】図５
