Buffer stop block and damping combined energy dissipation type bridge anti-seismic structure
The invention relates to the technical field of bridge seismic resistance, in particular to a buffer stop block and damping combined energy dissipation type bridge anti-seismic structure which comprises a steel corbel assembly, a top plate, a web plate with a rubber seismic resistance layer on the inner side face, a cubic sliding block, a damping device and a connecting device. The steel corbel assembly is fixed above the side wall of the bridge pier; The top plate is fixed to the bottom of the main beam, one section of each web is connected with one end of the bottom of the top plate throughangle steel, and the other end of each web is connected with the top of the steel corbel. Damping is arranged on the front side of the rear cubic sliding block, the two sliding blocks are connected with the connecting device through protruding cylindrical blocks on the left side and the right side, and in the connecting device, wavy stripes are arranged at the positions making contact with the cylindrical blocks so as to increase friction. Overlarge displacement of the beam body and the bridge piers in the bridge direction can be limited, the beam falling phenomenon is avoided, energy is absorbed, and therefore damage of earthquakes to the bridge is reduced, and the energy of the earthquakes is absorbed.
本发明涉及桥梁抗震技术领域，尤其涉及一种缓冲挡块和阻尼结合耗能型桥梁抗震结构，包括钢牛腿组件、顶板、内侧面带有橡胶抗震层的腹板、立方体滑块、阻尼装置、连接装置，所述钢牛腿组件固定于桥墩的侧壁上方，所述顶板固定于主梁的底部，两块所述腹板的一段通过角钢与所述顶板的底部一端相连，另一端与所述钢牛腿的顶部连接；所述立方体滑块，后方一块前侧装有阻尼，两滑块通过左右两侧突出的圆柱块与连接装置连接，且连接装中，与圆柱块接触处有波浪形条纹以增大摩擦。本发明能够限制梁体和桥墩的顺桥向过大位移，避免发生落梁现象，吸收能量，从而减少地震对桥梁的损坏，吸收地震的能量。
