Wind-resistant support-C-shaped steel combined structure of long-span bridge
The invention relates to a wind-resistant support-C-shaped steel combined structure of a long-span bridge. An existing wind-resistant support cannot meet the function of protecting a bridge, so that earthquake force is transmitted to the bridge, and the bridge is damaged. The structure is arranged between the outer side of a beam body and the inner side of a tower body and comprises a top plate, a bottom plate, a bottom basin, a fixed seat and C-shaped steel, the top plate is fixed on the outer side of the beam body; the bottom plate is fixed on the inner side of the tower body; the fixed seat and the bottom basin are positioned between the top plate and the bottom plate, the fixed seat is arranged on the top plate, the bottom basin is arranged on the bottom plate, and the C-shaped steel is connected between the end part of the fixed seat and the end part of the bottom basin through the shear pin. In the invention, the C-shaped steel with the energy consumption effect is matched with the wind-resistant support for use, so that the problem of poor damping effect when the wind-resistant support is independently used under the earthquake action is solved, and the problems that the shock insulation function cannot be realized and the installation and arrangement are difficult when the C-shaped steel is independently used in a high-intensity earthquake area or a near-fault site are also solved; the structure is simple and functions are obvious.
本发明涉及一种大跨度桥梁的抗风支座‑C型钢联合结构。现有抗风支座无法满足保护桥梁功能，导致地震力传递至桥梁，致使桥梁受损。本结构设置在梁体的外侧与塔身的内侧之间，包括顶板、底板、底盆、固定座和C型钢；顶板固定在梁体的外侧，底板固定在塔身的内侧；固定座和底盆位于顶板和底板之间，固定座设置在顶板上，底盆设置在底板上，C型钢通过剪力销连接在固定座的端部和底盆的端部之间。本发明中，具有耗能作用的C型钢与抗风支座配合使用，不仅解决了在地震作用下单独使用抗风支座时减震效果差的问题，同时也解决了单独使用C型钢在高烈度地震区或近断层场地条件下无法实现隔震功能以及安装布置困难的问题，构造简单，功能显著。
