Fabricated self-resetting concrete pier with shear-resistant energy consumption device
The invention discloses a fabricated self-resetting concrete pier with a shear-resistant energy consumption device, which is characterized in that a high-damping rubber pad is arranged in a groove on the upper surface of a bearing platform, and the pier is fixed on the high-damping rubber pad. A vertical hole channel is formed in the pier and extends from the lower bottom face of the pier to the interior of the pier body. The pier peripheral concrete structure is poured between the periphery of the pier and the bearing platform, the lower ends of the unbonded prestressed steel bars are anchored in the bearing platform, and the upper ends of the unbonded prestressed steel bars sequentially penetrate out of the bearing platform and the pier peripheral concrete structure and then are tensioned on the upper surface of the pier peripheral concrete structure. The embedded part is embedded in the bearing platform, the lower end of the protection pipe and the lower end of the energy consumption rod are fixed to the embedded part, and the protection pipe and the energy consumption rod penetrate through the bearing platform and then are tightly inserted into the hole channel. According to the fabricated self-resetting concrete pier with the shear-resistant energy consumption device, equivalent cast-in-place connection and prestress connection are combined, the energy consumption capacity of the pier is effectively compensated, and the pier has the anti-seismic energy consumption capacity and the self-resetting capacity.
本发明公开一种带抗剪耗能装置的装配式自复位混凝土桥墩，包括：承台的上表面上的凹槽中具有高阻尼橡胶垫，桥墩固定在高阻尼橡胶垫上。桥墩中设置有竖向孔道，孔道从桥墩的下底面向墩体内部延伸。桥墩外围混凝土结构浇筑在桥墩的外围和承台之间，无粘结预应力钢筋下端锚固在承台中，上端依次穿出承台、桥墩外围混凝土结构后张拉在桥墩外围混凝土结构的上表面上。预埋件预埋在承台中，保护管和耗能棒的下端均固定在预埋件上，保护管和耗能棒均穿过承台后紧密插入孔道中。本发明的这种“等同现浇”连接和预应力连接相结合的带抗剪耗能装置的装配式自复位混凝土桥墩不仅有效补偿了桥墩本身的耗能能力，使本发明桥墩兼具抗震耗能能力和自复位能力。
