SEISMIC ISOLATOR AND SEISMIC ISOLATION METHOD
PROBLEM TO BE SOLVED: To provide a seismic isolator for relieving vertical vibration to a house caused by an earthquake.SOLUTION: A seismic isolator 100 comprises a support leg 1, a slide pan 2 for slidably bearing the support leg 1 and an elastic member 14 for energizing a house in the vertical upward direction. The support leg 1 comprises a slide member 13 for sliding on a slide receiving surface 2a of the slide pan 2 in a lower end part, and the slide member 13 preferably comprises a large number of semispherical projections 131c abutting on the slide receiving surface 2a and is oscillatably supported in the omni-direction by the support leg 1, and is also preferably provided with falling-off prevention means 3 for preventing falling-off of the support leg 1 from the slide pan 2. The falling-off prevention means 3 comprises an endless wire 33 provided slidably and also in plane symmetry by sandwiching the support leg 1 or in rotation symmetry around the support leg 1, in a plurality of upper side slide locking parts 31 provided in the support leg 1 and a plurality of lower side slide locking parts 32 provided on the slide pan 2.
【課題】家屋の地震による鉛直方向の振動を緩和する免震装置を提供する。【解決手段】免震装置１００は、支持脚１と、支持脚１を滑動自在に支承する滑動受皿２と、家屋を鉛直上向きに付勢する弾性部材１４とを備える。支持脚１は下端部に滑動受皿２の滑動受面２ａ上を滑動する滑動部材１３を有し、滑動部材１３は、滑動受面２ａに当接する多数の半球状突起１３１ｃを有するとともに、支持脚１により全方向に首振り可能に支持されていることが好ましい。また、支持脚１の滑動受皿２からの脱落を防止する脱落防止手段３を備えることが好ましい。脱落防止手段３は、支持脚１に設けられる複数の上側摺動係止部３１と滑動受皿２に設けられる複数の下側摺動係止部３２とに摺動可能に、かつ、支持脚１を挟んで面対称に、又は支持脚１の周りに回転対称に設けられる無端ワイヤ３３を備える。【選択図】図１
