Corrugated steel arch type reinforcing structure of simply supported girder bridge and reinforcing method of corrugated steel arch type reinforcing structure
A bridge plate is erected between abutment caps of two bridge abutments of an original simply supported girder bridge structure, the reinforcing structure comprises a reinforcing corrugated top plate, the reinforcing corrugated top plate is fixedly arranged between the side walls of the bridge abutments on the two sides in a spanning mode, and the reinforcing corrugated top plate is bent upwards to be of an arch-shaped structure; the reinforcing corrugated top plate is pressed by the bridge plate and deforms downwards, and an upward supporting force is provided for the bridge plate. The structure has no burden on the dead weight of a bridge, the reinforcing corrugated top plate bent upwards to be in an arch shape is fixed to the side walls of the bridge abutments on the two sides, the balance weight is installed through the multiple sets of traction rings downwards arranged in the middle of the reinforcing corrugated top plate, the installation condition of the bridge plate is met, and then the balance weight is detached; the arch-shaped reinforcing corrugated top plate provides upward stable supporting force for the bridge plate, so that reinforcing of an old bridge and a dangerous bridge is achieved, the problems of sinking, cracking and the like of bridge bodies of the old bridge and the dangerous bridge are solved, meanwhile, the anti-bending and anti-shearing bearing capacity of the bridge is improved, and the reinforcing effect is remarkable.
本发明涉及一种简支梁桥的波纹钢拱式加固结构及其加固方法，原有简支梁桥结构的两个桥台的台帽之间架设有桥梁板，加固结构包括加固波纹顶板，加固波纹顶板固定跨设在两侧的桥台侧壁之间，加固波纹顶板上弯呈弓形结构，加固波纹顶板被桥梁板下压向下变形，给桥梁板一个向上的支撑力。本发明结构对桥梁的自重无负担，其将上弯呈弓形的加固波纹顶板固定于两侧桥台侧壁上，通过固波纹顶板中部向下设置的多组牵引环安装配重，使之达到桥梁板的安装条件，然后卸掉配重，通过弓形的加固波纹顶板给桥梁板提供一个向上的稳定支撑力，从而实现旧桥和危桥的加固，解决旧桥和危桥桥体下沉、裂缝等问题，同时提高了桥梁抗弯抗剪承载能力，加固效果显著。
