The invention discloses a highway bridge expansion joint structure which comprises two beam bodies. A mortar layer is fixedly mounted on each beam body at a bridge expansion joint, a concrete layer is fixedly connected to each mortar layer, a toothed plate is fixedly mounted on each concrete layer, teeth of the two toothed plates are mutually engaged and overlapped together to cover the bridge expansion joint, the two toothed plates can move relatively, two beam bodies at the bridge expansion joint are provided with circular grooves and are fixedly connected with rubber waterstops through the circular grooves, and the tail ends of the rubber waterstops are fixedly connected with drainage pipes communicated to the outside. Damping mechanisms used for bridge damping are arranged on the two bridge bodies at the bridge expansion joint. Through the cooperation of the whole mechanism, when the change of thermal expansion and cold contraction of the bridge expansion joint is caused by climate change, the tooth parts of the two toothed plates are mutually embedded or pulled out, so that the smoothness of a road surface is ensured, the bridge expansion joint cannot sink or protrude, and the effect of avoiding vehicle bumping in the driving process is achieved.
本发明公开了一种公路桥梁伸缩缝结构，包括两个梁体，桥梁伸缩缝处的每个梁体上均固定安装有砂浆层，每个砂浆层上均固定连接有混凝土层，每个混凝土层上分别固定安装有齿板，两个齿板的齿牙相互咬合搭接在一起将桥梁伸缩缝予以遮盖，两个齿板之间能够相对移动，桥梁伸缩缝处的两个梁体开设有圆槽并通过圆槽固定连接有橡胶止水带，橡胶止水带的末端固定连接有连通至外界排水管，桥梁伸缩缝处的两个梁体上设有用于桥梁减震的减震机构。本发明通过整体机构的配合，当气候变化带来桥梁伸缩缝的热胀冷缩的变化时，两个齿板的齿部相互嵌入或拔出保证了路面的平整性使得桥梁伸缩缝不会凹陷或凸起从而在行车过程中不会出现跳车的效果。
