Resettable multidirectional movable support with vibration absorption and isolation effects
The invention relates to the technical field of bridge vibration resistance, and particularly relates to a resettable multidirectional movable support with vibration absorption and isolation effects.The support comprises an upper support plate, a lower support plate, a main plate, a first vibration isolation sleeve, a second vibration isolation sleeve, a first vibration absorption buffer rod anda second vibration absorption buffer rod. The main plate is fixed at the top of the lower support plate; the top of the second vibration isolation sleeve is fixedly connected with the bottom of the upper support plate; a main plate core of a tubular structure is arranged in the middle of the top of the main plate, a third hollow hemispherical rubber block is arranged at an opening in the top of the main plate core, and a spring connected with the third hollow hemispherical rubber block is arranged between the third hollow hemispherical rubber block and the bottom of an inner cavity of the mainplate core; and a vibration pad making contact with the first vibration isolation sleeve and the second vibration isolation sleeve is arranged between the top of the first vibration isolation sleeveand the bottom of the second vibration isolation sleeve. Earthquake energy can be effectively dissipated, the vibration absorption and isolation effects are achieved, and losses of a bridge are reduced; and an automatic resetting function of the device can be realized after vibration.
本发明涉及桥梁抗震技术领域，尤其涉及一种具有减震隔震效果的可复位多向活动支座，包括上支座板、下支座板、主板、第一隔振套筒、第二隔振套筒、第一减震缓冲杆和第二减震缓冲杆，所述主板固定于所述下支座板的顶部；所述第二隔振套筒的顶部固与所述上支座板的底部相连；所述主板的顶部中间设有呈管状结构的主板板心，所述主板板心的顶部开口处设有第三空心半球橡胶块，所述第三空心半球橡胶块与所述主板板心的内腔底部之间设有与之连接的弹簧；所述第一隔振套筒的顶部与所述第二隔振套筒的底部之间设有与两者接触的减震垫。本发明能够有效耗散地震能量，具有减震隔震效果，减少对桥梁的损耗；且震后能够实现装置自动复位功能。
