BASE ISOLATION FOUNDATION STRUCTURE AND WATER CUTOFF MEMBER
PROBLEM TO BE SOLVED: To provide a base isolation foundation structure capable of preventing rainwater from infiltrating from a clearance between an upper dividing part and a lower dividing part of a foundation constituting part of a building, and capable of also cutting off water even if the displacement residue due to an earthquake is generated.SOLUTION: A ground surface side wide part 11 of a foundation constituting part 1 of a building 100 is divided into an upper dividing part 11a and a lower dividing part 11b, and a base isolation mechanism 3 is interposed between the upper dividing part 11a and the lower dividing part 11b. An outdoor side end part between the upper dividing part 11a and the lower dividing part 11b is provided with a water cutoff member 2 having a plurality of flexible projection parts 2a, a support member 4 for supporting the water cutoff member 2, and a receiving member 3 having a contact surface 3a for being in contact with the flexible projection parts 2a. The plurality of flexible projection parts 2a are deformed and moved while being in contact with the receiving member 3 in response to positional displacement between the upper dividing part 11a and the lower dividing part 11b, and at least one flexible projection part 2a secures a state of being in contact with the receiving member.
【課題】建物の基礎構成部の上分断部と下分断部の隙間から雨水が浸入するのを防止でき、また、地震による変位残留が生じたとしても止水が可能な免震基礎構造を提供する。【解決手段】建物１００の基礎構成部１の地面側広幅部１１が上分断部１１ａと下分断部１１ｂとに分断され、これら上分断部１１ａと下分断部１１ｂの間に免震機構３が介在されている。上記上分断部１１ａと下分断部１１ｂとの間の屋外側端部には、複数の柔軟性凸部２ａを有する止水部材２と、上記止水部材２を支持する支持部材４と、上記柔軟性凸部２ａが接触する接触面３ａを有する受け部材３と、が備えられており、上記複数の柔軟性凸部２ａが、上記上分断部１１ａと下分断部１１ｂとの位置変位に応じて上記受け部材３に接触しながら変形および移動するとともに、少なくとも１個の柔軟性凸部２ａが上記受け部材に接触する状態を確保する。【選択図】図２
