Multi-stage fortified seismic mitigation and absorption support
The invention relates to the technical field of bridge supports, in particular to a multi-stage defense seismic mitigation and absorption support. The support comprises an upper connecting steel plate, an upper sliding cover plate, energy dissipation soft steel, shear keys and a lower connecting steel plate, the upper connecting steel plate is of a cylindrical structure and is fixed to the bottomof a bridge, a groove with a circular cross section is formed in the middle of the lower surface of the upper connecting steel plate, and the upper sliding cover plate is of a circular structure and is fixed to the top wall of the groove through the shear keys; the energy dissipation soft steel is of a strip-shaped structure, one end of the energy dissipation soft steel is fixed to the side wall of the groove, and a gap is formed between the other end of the energy dissipation soft steel and the upper sliding cover plate. The lower connecting steel plate is fixed to the top of a pier, and a lead core rubber vibration isolation support is arranged between the lower connecting steel plate and the upper sliding cover plate. The support has the advantages of being simple in structure, clear instress and the like, and multi-stage fortification and graded energy consumption under earthquakes of different intensities can be achieved.
本发明涉及桥梁支座技术领域，尤其涉及一种多级设防的减隔震支座，包括上连接钢板、上滑动盖板、耗能软钢、剪力键和下连接钢板，所述上连接钢板呈圆柱形结构固定于桥梁底部，其下表面中部形成横截面呈圆形的凹槽，所述上滑动盖板呈圆形结构通过若干所述剪力键固定于所述凹槽的顶壁上；所述耗能软钢呈条状结构，其一端固定于所述凹槽的侧壁上，另一端与所述上滑动盖板之间设有间隙；所述下连接钢板固定于桥墩的顶部，所述下连接钢板与所述上滑动盖板之间设有铅芯橡胶隔振支座。本发明具有结构简单、受力明确等特点，能够实现不同强度地震下的多级设防和分级耗能。
