Elastic sliding plate seismic isolation bearing
The invention relates to an elastic sliding plate seismic isolation bearing. The elastic sliding plate seismic isolation bearing comprises an upper connecting plate, a lower connecting plate, an elastic seismic isolation assembly provided with an upper sealing plate and a lower sealing plate, a first sliding plate arranged on the upper connecting plate, a second sliding plate arranged on the uppersealing plate and matched with the first sliding plate in a sliding manner, a third sliding plate arranged on the lower connecting plate, a fourth sliding plate arranged on the lower sealing plate and matched with the third sliding plate in a sliding manner, a first limit ring arranged on the upper connecting plate and used for limiting sliding distance of the second sliding plate and a second limit ring arranged on the lower connecting plate and used for limiting sliding distance of the fourth sliding plate. According to the elastic sliding plate seismic isolation bearing, by two sliding surfaces arranged between the first sliding plate and the second sliding plate as well as between the third sliding plate and the fourth sliding plate, sliding energy consumption of the bearing in stagesis realized, and by cooperation of the first limit ring and the second limit ring, deflection of ultra-extreme displacement is effectively limited and safety performance of the bearing is improved. The bearing is provided with an inhaul cable, the vertical tensile discontinuity characteristic of the bearing is changed, and the risk of capsizing under the extreme operating condition can be effectively prevented.
本发明涉及一种弹性滑板隔震支座，包括上连接板、下连接板、具有上封板和下封板的弹性隔震组件、设置在上连接板的第一滑板、设置在上封板且与第一滑板滑动匹配的第二滑板、设置在下连接板的第三滑板、设置在下封板且与第三滑板滑动匹配的第四滑板、设置在上连接板的用于限制第二滑板滑动距离的第一限位环及设置在下连接板的用于限制第四滑板滑动距离的第二限位环。通过第一滑板和第二滑板之间及第三滑板和第四滑板之间的二个滑动面的设置，实现支座分阶段滑动耗能，并配合第一限位环和第二限位环，有效限制了超极端位移的变位，提高支座的安全性能。该支座还设置拉索，改变了支座竖向抗拉不连续特性，可有效防范极端工况下倾覆的危险。
