Bridge deck bending and twisting control device for large-span bridge
The invention discloses a large-span bridge deck bending and twisting control device, and relates to the technical field of large-span bridges, the large-span bridge deck bending and twisting control device comprises a large-span bridge body, a cross beam is arranged at the bottom of a bridge tower of the large-span bridge body, and the cross beam is located at the bottom of a bridge deck slab of the large-span bridge body; two sets of first lower lug plates are symmetrically fixed to the right side of the top of each set of cross beams in the front-back direction, regulation and control assemblies used in cooperation with a large-span bridge body are arranged on the cross beams, and by arranging the regulation and control assemblies, a negative stiffness system is formed by pre-pressing springs and levers, the bottom shearing force of the structure is reduced, and the stability of the structure is improved. The stroke of the damper is amplified according to the lever principle, the energy consumption of the damper is increased, and the requirement for the tonnage of the damper is reduced. The vertical bending and twisting control system is formed by the multiple sets of regulation and control assemblies arranged on the two sides of the bridge deck of the large-span bridge body together, vertical displacement of the two sides of the bridge deck of the large-span bridge body in the same direction or different directions can be controlled at the same time, the bending and twisting degree of the bridge deck of the large-span bridge body is reduced, and the vertical damping performance of the large-span bridge is improved.
本发明公开了一种大跨桥梁桥面弯扭控制装置，涉及大跨度桥梁技术领域，包括大跨度桥梁本体，所述大跨度桥梁本体的桥塔底部设置有横梁，所述横梁位于大跨度桥梁本体的桥面板底部，每组所述横梁顶部的右侧沿前后方向对称固定有两组第一下耳板，所述横梁上设置有与大跨度桥梁本体配合使用的调控组件，通过设置调控组件，利用预压弹簧和杠杆组成负刚度系统，减小结构的底部剪力，利用杠杆原理对阻尼器行程进行放大，增大了阻尼器的耗能，减小了对阻尼器吨位的需求。布置在大跨度桥梁本体桥面板两侧的多组调控组件共同组成了竖向弯扭控制系统，可以同时控制大跨度桥梁本体桥面板两侧的同向或不同向的竖向位移，减小了大跨度桥梁本体桥面板的弯扭程度，提高了大跨度桥梁的竖向减震性能。
