Mortise and tenon joint type self-resetting pier with half-moon-shaped energy dissipater
The tenon-and-mortise type self-resetting pier comprises a half-cast-in-place pier, an upper segment pier, a half-moon-shaped energy dissipater body and prestressed tendons, a fixing groove is formed in the upper portion of the half-cast-in-place pier, a rubber cushion layer is laid on the fixing groove, a tenon is arranged on the lower portion of the upper segment pier, and the half-moon-shaped energy dissipater body is arranged on the lower portion of the half-moon-shaped energy dissipater body. The tenon is in a downward protruding shape, a second notch is formed in the periphery of the tenon, and the second notch is in an inward concave shape. According to the tenon-and-mortise type self-resetting pier with the half-moon-shaped energy dissipater, the half-moon-shaped energy dissipater body is arranged, energy dissipation pieces are made of low-yield-point steel, and energy dissipation parts do not need to be arranged through expensive materials or advanced technologies; the energy dissipation piece is designed to be detachably installed, after the energy dissipation piece is damaged in an epicenter, the performance of the pier can be restored by timely replacing the energy dissipation piece, cost and carbon emission can be reduced, and the half-moon-shaped steel plates located on the energy dissipation piece can be additionally arranged and reduced according to different working conditions and engineering requirements.
本发明公开了一种具备半月形耗能器的榫卯式自复位桥墩，包括半现浇桥墩、上部节段桥墩、半月形耗能器主体和预应力筋，所述半现浇桥墩上方开设有固定槽，且固定槽上方铺设有橡胶垫层，所述上部节段桥墩下方开设有榫头，且榫头呈向下凸起状，所述榫头周围开设有第二槽口，且第二槽口呈向内凹陷状。该具备半月形耗能器的榫卯式自复位桥墩，设置有半月形耗能器主体，该耗能件由低屈服点钢材制成，不需要采用昂贵的材料或先进的技术设置耗能部件；该耗能件被设计为可拆卸安装，在震中损害后，通过及时更换即可保证桥墩恢复性能，有利于降低成本及减少碳排放，位于耗能器上的半月形钢板可以根据不同的工况以及工程需求来进行增设和减少。
