Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] For example, Figures 1 to 5As shown, a bridge seismic isolation structure includes a support column 1; a first damping groove 12 is formed at the top of the support column 1, a connecting column 13 is slidably connected to the inner side of the first damping groove 12, a bridge connecting seat 14 is fixedly connected to the top of the connecting column 13, a bridge plate 15 is fixedly connected to the top of the bridge connecting seat 14, a first damping block 16 is fixedly connected to the inner side of the first damping groove 12, a first sliding groove 17 is formed on the side of the connecting column 13, the first damping block 16 is slidably connected to the first sliding groove 17, a first spring 18 is fixedly connected to the inner side of the first sliding groove 17, the top of the first spring 18 is fixedly connected to the first damping block 16, a first damping rod 19 is fixedly connected to the inner side of the first sliding groove 17, the first damping rod 19 is slidably connected to the first damping block 16, a spring plate 110 is fixedly connected to the inner side of the first damping groove 12, and the surface of the spring plate 110 is in contact with the connecting column 13; during operation, when the bridge plate 15 vibrates, the bridge plate 15 drives the bridge connecting seat 14 to vibrate. The bridge connecting seat 14 causes the connecting column 13 to vibrate, causing the connecting column 13 to move inside the first damping groove 12. The connecting column 13 is supported by the spring plate 110. The connecting column 13 is pushed back to its original position from the bottom. When the connecting column 13 moves, it simultaneously drives the first spring 18 and the first slide groove 17 to move. Through the connection of the first damping block 16, the first damping rod 19, and the first spring 18, the first spring 18 pulls the connecting column 13 to move. The first damping rod 19 increases the friction between itself and the first damping block 16, absorbing the vibration energy of the connecting column 13. In this step, the spring plate 110 pushes the bottom of the connecting column 13 to dampen it. The first spring 18 pulls the connecting column 13 back to its original position. The first damping rod 19 increases the resistance between itself and the first damping block 16, absorbing the kinetic energy of the vibration of the connecting column 13 and reducing the vibration energy of the connecting column 13, thus achieving the effect of damping the bridge plate 15.

[0027] As shown in Figure 1 As shown, the bottom of the support column 1 is fixedly connected with a support base 61, and the top of the support base 61 is fixedly connected with a reinforcing frame 62; this step expands the support area of the bottom of the support column 1 through the support base 61 and the reinforcing frame 62, thereby increasing the stability of the support column 1 during support.
