Bridge reinforcing system for reducing bridge deck vibration
The invention discloses a bridge reinforcing system for reducing bridge deck vibration. The system comprises inclined plates, a bridge and piers, and the upper and lower sides of the left and right inclined plates are in threaded connection with the bridge and the piers through bolts; a triangular structure is formed among a first supporting rod, a second supporting rod, the inclined plates and the piers so that the piers and the inclined plates are connected into a whole, and the stability of the inclined plates is improved; a buffer spring and an extrusion spring support a piston disc; and when the inclined plates are extruded to deform, the first supporting rod and the second supporting rod can buffer an extrusion force, reduce vibration of the inclined plates and decrease a vibration frequency difference between the inclined plates and the piers, and damping holes are formed in the piston disc so that the piston disc can only slowly move in a piston cylinder to buffer vibration, and a supporting effect on the two sides of the wall surface is improved.
本发明公开了一种降低桥面震动的桥梁加固系统，包括斜板、桥梁和桥墩，左右所述斜板的上下两侧通过螺栓分别螺纹连接有桥梁和桥墩；利用第一撑杆、第二撑杆、斜板与桥墩之间构成一个三角形结构，使桥墩与斜板连接为一个整体，提升了斜板的稳定性；缓冲弹簧与挤压弹簧支撑活塞盘，当斜板挤压变形时，第一撑杆与第二撑杆能够对挤压力进行缓冲，降低斜板震动，减少斜板与桥墩之间震动频率差，且活塞盘上设置阻尼孔，使得活塞盘仅能缓慢在活塞缸中移动，对震动进行缓冲，提高对墙面两侧的支撑效果。
