Limiting swing type seismic mitigation and isolation bearing platform structure
The invention discloses a limiting swing type shock absorption and isolation bearing platform structure which comprises a bearing platform lower portion, a bearing platform upper portion, a prestress system and a limiting recovery device. The upper surface of the lower part of the bearing platform is connected with the lower surface of the upper part of the bearing platform, and is a convex spherical surface and a concave spherical surface respectively to form spherical crown-shaped compaction; an upper sliding steel plate is arranged on the lower surface of the bearing platform; a lower sliding steel plate is arranged on the upper surface of the lower bearing platform; a viscous damping coating is arranged between the upper sliding steel plate and the lower sliding steel plate; the pre-stress system comprises a plurality of pre-stress rods with low shear strength arranged between the lower part of the bearing platform and the upper part of the bearing platform; the limiting recovery device comprises a plurality of steel strands or steel wire ropes penetrating through the upper portion of the bearing platform upwards from the lower portion of the bearing platform. The post-earthquake sliding deformation recoverable performance is achieved, and post-earthquake overhaul and reinforcement are facilitated; and shock absorption and isolation displacement is controllable, and overturning is avoided in the earthquake.
本发明公开了限位摇摆式减隔震承台结构，包括承台下部、承台上部、预应力体系和限位恢复装置；承台下部的上表面与承台上部的下表面相接，分别呈外凸的球形面和内凹的球形面，形成球冠状压密；承台上部的下表面设有上滑动钢板；承台下部的上表面设有下滑动钢板；上滑动钢板和下滑动钢板之间设有粘滞阻尼涂层；预应力体系包括设置在承台下部和承台上部之间的多根低剪切强度的预应力棒；限位恢复装置包括多根从承台下部向上贯承台上部的钢绞线或钢丝绳。本发明具有震后滑动变形可回复性能，便于震后检修加固；减隔震位移可控，震时不会倾覆的优点。
