Mountainous area bridge anti-seismic support and construction method thereof
The invention belongs to the technical field of bridge anti-seismic engineering application, and particularly discloses a mountainous area bridge anti-seismic support. Comprising a bridge pier, a bridge, a concrete base, a plurality of vertical screw sleeves, a plurality of screws, screw adjusting nuts, a transition supporting part, a transition supporting part through hole, a limiting part, a buffer block limiting groove, a lower buffer block, a lower buffer block through groove, an upper buffer, a bridge supporting plate and the like. The invention has the following beneficial effects: 1, the overall design is reasonable, and the fabricated structure is adopted, so that the construction and assembly precision is improved by utilizing assembly construction; 2, the inspection and maintenance are convenient, the lower buffer block can be pushed out through a lower buffer block through groove by utilizing a transverse limiting part screw hole and a lower buffer block push-out screw rod to be replaced, and the conventional and stable anti-seismic and shock-absorbing effect is ensured; and 3, a plurality of inclined supporting seats, an open-type limiting lower seat, an open-type limiting upper seat and a shearing-type metal mild steel damper structure are additionally arranged, and form a secondary anti-seismic and shock-absorbing structural design with an upper buffer block and a lower buffer block, so that the anti-seismic and shock-absorbing effect is improved.
本发明属于桥梁抗震工程应用技术领域，具体公开了一种山区桥梁抗震支座，包括桥梁墩、桥梁、混凝土基座、若干个竖螺套、若干个螺杆、螺杆调节螺母、过渡支撑部、过渡支撑部通孔、限位部、缓冲块限位槽、下缓冲块、下缓冲块通槽、上缓冲和桥梁支撑板等。本发明的有益效果在于：1、整体设计合理，且为装配式结构，利用组装施工，提高施工装配精度；2、便于检维，能对下缓冲块利用横限位部螺孔、下缓冲块推出螺杆通过下缓冲块通槽推出进行更换，保证常规稳定的抗震减震效用；3、增加的若干个斜支撑座、敞开式限位下座、敞开式限位上座和剪切型金属软钢阻尼器结构，与上缓冲块、下缓冲块之间构成二级的抗震减震结构设计，提高抗震减震效果。
