the position relation of the opening span 1 and the fixed span 2 comprises an opening state and a closing state;

when the opening span 1 and the fixed span 2 are in an opening state, the left telescopic seam plate 12 is positioned above the right telescopic seam plate 22;

when the opening span 1 and the fixed span 2 are in a closed state, the middle part of the left telescopic seam plate 12 is contacted with the right base plate 21, and the right end of the left telescopic seam plate 12 is occluded with the left end of the right telescopic seam plate 22.

The right end of the left base plate 11 is connected with a left telescopic seam plate 12 through an extension spring 111; the relatively high-rigidity extension spring 111 is used for reinforcing the connection between the left base plate 11 and the left expansion joint plate 12, and simultaneously preventing the right end of the left expansion joint plate 12 from tilting to a certain extent.

In order to reduce the damage to the expansion joint caused by the impact action when the open bridge is closed, a vibration damping component 122 is arranged at the contact position of the left expansion joint plate 12 and the right base plate 21; the vibration damping assembly 122 is connected with the left telescopic seam plate 12 through a screw 123; the dampening assembly 122 also has a water-resistant effect in the closed state, which is beneficial to the durability of the structure.

And the right base plate 21 is provided with a stainless steel plate 211, so that the expansion joint can freely move when the beam body longitudinally contracts.

The fixed span 2 further comprises an anchoring rib 23, the anchoring rib 23 fixes the right base plate 21 and the right telescopic seam plate 22, and the anchoring rib 23 is located in the fixed span 2.
