Reinforcing structure for cracked steel bridge deck slab
The invention relates to the technical field of steel bridge deck slab reinforcement, and particularly discloses a reinforcing structure for a cracked steel bridge deck slab, which comprises a cracked steel bridge deck slab body, a fiber reinforced composite material layer is arranged above the cracked steel bridge deck slab body, and a support connecting piece is arranged above the fiber reinforced composite material layer. A plurality of reinforcing rib plates are arranged in the supporting connecting piece, a buffer filling layer is arranged on one side of each reinforcing rib plate, a reinforcing mesh layer is arranged above the supporting connecting piece, a concrete layer is arranged above the reinforcing mesh layer, and a wear-resistant layer is arranged above the concrete layer; a plurality of connecting bolts are vertically arranged below the supporting connecting piece; by arranging the fiber reinforced composite material layer on the cracked steel bridge deck slab body, the steel bridge deck slab is reinforced, the risk that the steel bridge deck slab continues to crack is avoided, meanwhile, existing cracks cannot continue to expand and develop, and the anti-fatigue life of the steel bridge deck slab is prolonged.
本发明涉及钢桥面板加固技术领域，具体公开了一种用于开裂钢桥面板的加固结构，包括开裂钢桥面板本体，开裂钢桥面板本体的上方设置有纤维增强复合材料层，纤维增强复合材料层的上方设置有支撑连接件，支撑连接件内设置有多块加强肋板，且每块加强肋板的一侧均设置有缓冲填充层，支撑连接件的上方设置有钢筋网层，钢筋网层的上方设置有混凝土层，混凝土层的上方设置有耐磨层；支撑连接件的下方竖向设置有多根连接螺栓，通过在开裂钢桥面板本体上设置纤维增强复合材料层，对钢桥面板进行加固，避免钢桥面继续开裂的风险，同时已存在的裂缝不会再继续扩大发展，延长其抗疲劳寿命。
