Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to an assembled composite structure bridge. Background Art

[0002] A bridge is a building structure used to connect two locations or a path across an obstacle. It is usually constructed of building materials such as concrete, steel, and stone to support transportation facilities such as sidewalks, roads, railways, or pipelines. Bridges can be of different types such as suspension bridges, arch bridges, beam bridges, and cable-stayed bridges. Each type has its own unique design and construction method. The main function of a bridge is to provide convenience, promote traffic flow, shorten travel distances, and connect different regions and communities.

[0003] When assembling existing bridges, the bridge plate is directly fixed on the bridge foundation. When the bridge assembled in this way is in use, when the bridge plate vibrates, the vibration force generated will be directly transmitted to the bridge foundation, which will cause the stability of the bridge foundation to decrease, making the bridge potentially dangerous.

[0004] To this end, we propose an assembled composite structure bridge to solve the above problems. Utility Model Content

A first connecting plate 31 is fixedly provided on the lower surface of the bridge plate 1, and a second connecting plate 32 is fixedly provided on the upper surface of the support plate 11. The first connecting plate 31 is slidably connected to the second connecting plate 32. When the bridge plate 1 is subjected to vibration force, the second spring shock absorber 3 is deformed. At the same time, the bridge plate 1 drives the first connecting plate 31 to move up and down under the action of the vibration force. By arranging the second spring shock absorber 3, the first connecting plate 31 and the second connecting plate 32, the stability of the connection between the bridge plate 1 and the support plate 11 is increased, and the shock absorbing effect of the bridge is also improved.

[0028] A plurality of telescopic rods 4 are fixedly provided between the bridge plate 1 and the support plate 11 . By providing the telescopic rods 4 , the stability of the connection between the bridge plate 1 and the support plate 11 can be increased.

[0034] Working principle: First, when the bridge plate 1 is subjected to vibration force, the vibration force exerted on the bridge plate 1 is transmitted to the top plate 20, and the top plate 20 is subjected to the vibration force and moves up and down. The top plate 20 drives one end of the first connecting plate 22 to rotate through the first connecting member 21, and one end of the first connecting plate 22 drives one end of the second connecting plate 24 to rotate through the connecting rod 23 during the rotation process. When one end of the first connecting plate 22 and the second connecting plate 24 are rotating, they drive the stabilizing block 200 to move in the opposite or reverse direction. At the same time, the top plate 20 drives the first slider 27 to move up and down. During the lifting and moving process of the first slider 27, the first spring shock absorber 29 is deformed, thereby buffering and offsetting the vibration force exerted on the bridge plate 1. By setting the shock absorbing assembly 2, the effect of buffering and offsetting the vibration force generated by the bridge plate 1 is achieved, thereby preventing the vibration force exerted on the bridge plate 1 from being transmitted to the bridge base 12, avoiding the decrease in the stability of the bridge base 12, and making the bridge safer to use.

[0035] Subsequently, when the bridge plate 1 is subjected to vibration force, the second spring shock absorber 3 is deformed. At the same time, the bridge plate 1 drives the first connecting plate 31 to move up and down under the action of the vibration force. By setting the second spring shock absorber 3, the first connecting plate 31, and the second connecting plate 32, the stability of the connection between the bridge plate 1 and the support plate 11 is increased, and the shock-absorbing effect of the bridge is improved.
