Bridge expansion joint protection structure
The invention discloses a bridge expansion joint protection structure, which comprises bridge piers, wherein the upper ends of the bridge piers are connected with bridge bodies in an attached mode, a supporting table is fixedly mounted at the upper ends of the bridge piers, a first groove is formed in the side wall of each bridge body, a mounting table is inserted into the first groove, a connecting column is fixedly connected to the lower end of the mounting table, a second groove is formed in the upper end of the supporting table, and the lower end of the connecting column is inserted into the second groove; when the bridge bodies are heated to expand, the mounting tables are inserted into the first grooves, so that enough gaps are reserved between the bridge bodies, potential safety hazards caused by jacking of the expansion joints due to extrusion of the bridge bodies are avoided, when the bridge bodies are cooled to contract, the connecting blocks drive the moving blocks to move at the upper ends of the mounting tables due to contraction of the bridge bodies, and gaps generated among the positioning blocks, the moving blocks, the connecting blocks and the bridge bodies can be supported through baffles, so that the gap formed by expansion and contraction of the bridge is smaller, and bumping is avoided when vehicles pass by.
本发明公开了一种桥梁伸缩缝防护结构，包括桥墩，所述桥墩的上端贴合连接有桥体，所述桥墩的上端固定安装有支撑台，所述桥体的侧壁开设有第一凹槽，所述第一凹槽的内部插接有安装台，所述安装台的下端固定连接有连接柱，所述支撑台的上端开设有第二凹槽，所述连接柱的下端插接在第二凹槽的内部；当桥体受热膨胀时，通过安装台插接在第一凹槽的内部，使得桥体之间留有足够的空隙，避免桥体挤压造成伸缩缝出顶起而产生安全隐患，当桥体受冷收缩时，桥体的收缩使得连接块带动移动快在安装台的上端移动，并通过挡板可以支撑定位块、移动块、连接块、桥体之间产生的缝隙，从而使桥梁伸缩缝出的缝隙更小，避免车辆经过时发生颠簸。
