INSTALLATION DEVICE FOR SEISMIC ISOLATION SLIDING BEARING
PROBLEM TO BE SOLVED: To provide an installation device for a seismic isolation sliding bearing, which enables a high flatness even with an enlarged base plate being used for fixing the sliding bearing and secures a desired seismic isolation performance.SOLUTION: An installation device 31 for a seismic isolation sliding bearing, which consists of a base plate 32 and adjusting bolts 37 and 39 that extend downward from the base plate 32 and adjust the height of the base plate, comprises: columns 33 which are formed along the outer circumference of the base plate 32; columns 34 which are formed also in the center part of the base plate 32; through holes which are formed through the base plate 32 at least at the position on the base plate where the center-part columns 34 are formed; and the heads of the adjusting bolts 37, which are located at the bottom of the through holes and operated from the top of and through the through holes.
【課題】免震すべり支承を固定するベースプレートを大きくしても高い平面度を得られるようにして、所望の免震性能を確保する設置装置を提供する。【解決手段】ベースプレート３２と、ベースプレート３２から下に延びるとともに高さ調整を行う調整ボルト３７，３９を有する支柱を備えた免震すべり支承設置装置３１において、ベースプレート３２の外周部に支柱３３を形成するとともに、ベースプレート３２の中央部にも支柱３４を形成し、ベースプレート３２における少なくとも中央部の支柱３４を形成する位置に、ベースプレート３２を貫通する貫通穴を形成し、貫通穴の下方に、貫通穴を介して貫通穴の上から操作される調整ボルト３７の頭部を備える。【選択図】図１
