Bridge expansion joint structure
The invention discloses a bridge expansion joint structure, and relates to the technical field of bridge expansion joint construction.The bridge expansion joint structure comprises a first comb tooth steel plate, a second comb tooth steel plate and elastic filler, and the first comb tooth steel plate is arranged on a bridge body on the first side of a bridge expansion joint; the second comb-tooth steel plate is arranged on a bridge body on the second side of the bridge expansion joint, the second comb-tooth steel plate is meshed with the first comb-tooth steel plate, the elastic filler is laid above the first comb-tooth steel plate and the second comb-tooth steel plate, and the elastic filler is connected with the first comb-tooth steel plate and the second comb-tooth steel plate to form a bridge expansion joint structure. According to the embodiment of the invention, an expansion joint structure formed by connecting the elastic filler with the first comb tooth steel plate and the second comb tooth steel plate forms good rigidity transition with a bridge plane, so that the situation that the rigidity is suddenly changed when a bridge expansion joint steel piece and steel fiber reinforced concrete filled in a joint are connected with asphalt on the top surface of a bridge is avoided; the impact force in the running process of the vehicle is reduced, and the running safety and comfort are improved.
本发明公开了一种桥梁伸缩缝结构，涉及桥梁伸缩缝施工技术领域，所述桥梁伸缩缝结构包括第一梳齿钢板、第二梳齿钢板和弹性填充物，第一梳齿钢板设于桥梁伸缩缝的第一侧的桥梁梁体上，第二梳齿钢板设于桥梁伸缩缝的第二侧的桥梁梁体上，第二梳齿钢板与第一梳齿钢板啮合，弹性填充物铺设于第一梳齿钢板与第二梳齿钢板上方，弹性填充物与第一梳齿钢板和第二梳齿钢板连接形成桥梁伸缩缝结构。本发明实施例的弹性填充物与第一梳齿钢板和第二梳齿钢板连接形成的伸缩缝结构与桥梁平面形成了良好的刚度过度，避免了桥梁伸缩缝钢件和缝内填充的钢纤维混凝土与桥梁顶面的沥青连接时刚度突变的情况，降低了车辆行驶中的冲击力，提高了行车安全和舒适度。
