Shock absorption and isolation energy dissipation rubber support and earthquake resistance grading fortification method thereof
The invention discloses a shock absorption and isolation energy dissipation rubber support and an anti-seismic grading fortification method thereof, and belongs to the technical field of beam bridge engineering. The rubber support comprises a support body, a limiting assembly, a shear switch and a friction assembly. The friction assembly is used for shock absorption and shock insulation; in a normal state, the shear switch limits the support body in the sliding area in the horizontal direction; otherwise, the shear switch does not limit the support body, and the support body slides in the sliding area. The safety and seismic mitigation and isolation performance of the rubber support body are greatly improved, and the rubber support has the advantages of being stable in structure, controllable in sliding and easy to replace and adjust in height, has higher cost performance and wider application range compared with an existing seismic mitigation and isolation support, can replace a seismic mitigation and isolation support of a seismic mitigation and isolation system bridge, and can also be widely applied to small and medium span beam bridges.
本发明公开了一种减隔震耗能橡胶支座及其抗震分级设防方法，属于梁桥工程的技术领域。橡胶支座包括：支座本体、限位组件、剪力开关和摩擦组件。所述摩擦组件用于减震、隔震；正常状态下，剪力开关水平向将支座本体限位于滑动区域内；反之，剪力开关对支座本体无限定，支座本体于滑动区域内滑移。本发明大大提升了橡胶支座本体的安全性和减隔震性能，具有结构稳定且滑移可控、易于更换、调高的优势，与现有减隔震支座相比具有更高的性价比，应用范围更广，除可替代减隔震体系桥梁的减隔震支座外，也可广泛用于中小跨径梁式桥。
