SEISMIC ISOLATING DEVICE
PROBLEM TO BE SOLVED: To provide a seismic isolating device that does not cause transverse deviation even when a building receives wind pressure, and exhibits a seismic isolation effect in receiving strong vibration of an earthquake, with a simple structure and at low cost.SOLUTION: A base plate 10 of a seismic isolating device comprises a plurality of metal plates 13a, 13b, 13c whose laminated contours has the substantially same shape, and a case 11 that houses the metal plates 13a, 13b, 13c. The metal plates have a concentric circle opening at a central part, and are housed in the case 11 in an ascending order of a diameter from a metal plate whose diameter is smallest, and thereby a cone-shape recess whose depth becomes deeper from the outer periphery of the case 11 toward its central part is formed by the edge parts of the openings of the laminated metal plates.
【課題】建物が風圧を受けても横ずれせず、地震の強い震動を受けたときには免震効果を発揮する免震装置を簡単な構造で、しかも低コストで提供する。【解決手段】免震装置のベースプレート１０は、積層された外形上が略同一の複数の金属板１３ａ，１３ｂ，１３ｃと、複数の金属板１３ａ，１３ｂ，１３ｃを収容するケース１１とからなり、複数の金属板は中央部に同心円の開口を有し、その直径が小さい金属板から先に、直径が大きくなる順でケース１１に収容していくことで、積層された複数の金属板の開口の縁部によって、ケース１１の外周から中央部に向かって深くなっていく擂鉢形状凹部が形成される。【選択図】図２
