Anti-seismic device for highway bridge
The invention discloses an anti-seismic device for a highway bridge. The device comprises a bridge floor, a damping cushioning device group, a bridge floor support body and a base, wherein the bridge floor support body is arranged on the base, the damping cushioning device group is arranged between the bridge floor and the bridge floor support body, and the damping cushioning device group comprises a first damping cushioning device and a second damping cushioning device; the first damping cushioning device and the second damping cushioning device are obliquely arranged; a first reinforcing rod and a second reinforcing rod are arranged on the first damping cushioning device and the second damping cushioning device, the upper end of the first reinforcing rod and the upper end of the second reinforcing rod are arranged on the bottom wall of the bridge floor, and the first reinforcing rod and the bridge floor supporting body sequentially comprise an upper reinforced concrete slab layer, an anti-seismic layer and a lower reinforced concrete slab layer from top to bottom; and the upper surface and the lower surface of the anti-seismic layer are not located on the same horizontal plane. The invention relates to the technical field of highway bridges, in particular to the anti-seismic device for the highway bridge, and the device can simultaneously realize longitudinal and transverse dual-damping energy dissipation effects and has a good anti-seismic effect on low-speed loads and high-speed loads.
本发明公开了一种公路桥梁用抗震装置，包括桥面、阻尼缓震器组、桥面支撑体和底座，桥面支撑体设于底座上，阻尼缓震器组设于桥面和桥面支撑体之间，阻尼缓震器组包括阻尼缓震器一和阻尼缓震器二，阻尼缓震器一和阻尼缓震器二倾斜设置，阻尼缓震器一和阻尼缓震器二上设有加固杆一和加固杆二，加固杆一和加固杆二上端设于桥面底壁上，加固杆一、桥面支撑体由上至下依次包括上钢筋混凝土板层、抗震层和下钢筋混凝土板层，抗震层上表面和下表面均不位于同一水平面上。本发明涉及公路桥梁技术领域，具体是提供了一种可同时实现纵向和横向双重阻尼耗能作用，且对低速荷载与高速荷载都有良好抗震效果的公路桥梁用抗震装置。
