摘　　要：对于梳齿板伸缩缝边角混凝土的磨损,利用角钢材料在伸缩缝底板端头加以保护,以防止行车荷载,温度变化对桥梁梳齿板伸缩缝处陶粒混凝土的破坏,起到了一定的保护作用,增强了桥梁梳齿板伸缩缝处边角混凝土的抗破坏能力.for the wear of the comer concrete in the extension joint of the comb tooth plate, we use the comer steel material to protect the end of the expansion seam plate, which prevents the driving load, and the temperature change has a certain protective effect on the destruction of the concrete at the extension joint of the bridge tooth plate. The damage resistance of the corner concrete at the extension joint of the bridge was enhanced.

关 键 词：梳齿板 伸缩缝 保护
