Embodiment 1
[0025] New bridge expansion joint structure: pre-embed the anchoring device 8 at the end of the main beam, connect and fix the sliding plate 9 and the anchoring device 8 on the surface of the main beam, the top surface of which is flush with the surface of the main beam, and install the bearing plate 2 above it , and apply lubricant in the lubricant groove 3, and install elastic deformation bodies 10 at both ends of the bearing plate 2. One end of the elastic deformation body 10 is fixedly connected with the bearing plate 2, and the other end should be fixedly connected with the connecting steel bars reserved for the main beam. After the installation is correct, pave the bridge deck pavement layer 1.
Embodiment 2
[0027] Replace the bridge expansion joint structure of the old bridge: connect the sliding plate 9 and the anchoring device 8 to the surface of the main beam 6, fix the sliding shaft 4 on the surface of the main beam 6, install the bearing plate 2 above it, and apply it to the lubricant groove 3 Lubricant, install the elastic deformation body 10 on both sides of the bearing plate 2, one end of the elastic deformation body 10 is fixedly connected with the bearing plate 2, and the other end should be fixedly connected with the connecting steel bar reserved for the main beam 6, after the above installation is correct, pave Bridge deck pavement layer 1.
