Description

Closed bridge
Technical Field
The utility model relates to a closed bridge.
Background
In the construction of highways, railways, cities and water conservancy, a building structure is built for crossing various obstacles (such as rivers, valleys or other routes) and is called a bridge.
The large-span bridge, as the name implies is exactly the great bridge of span, and the distance between its two piers is longer, leads to the bridge body tenesmus range great, leads to the bridge body fracture to collapse easily under the influence of bridge body dead weight, causes the incident.
SUMMERY OF THE UTILITY MODEL
The utility model provides a closed bridge to solve the technical problem that great span bridge shaft bridge body is tenesmic.
The technical scheme of the utility model is realized like this: the utility model provides a closed bridge, includes two at least piers, is equipped with the bridge body on the pier, be equipped with curved layer board between the pier, layer board top and bridge body contact are in order upwards to push away the bridge body, the opening direction of layer board is down, the layer board both ends are equipped with the connecting plate with adjacent pier fixed connection.
Further, a fixed seat is arranged below the pier, a sliding groove is formed in the upper end of the fixed seat, and a protruding block matched with the sliding groove to slide in the sliding groove is arranged at the lower end of the pier.
Furthermore, a connecting column is arranged between the two adjacent piers so as to keep the piers in a vertical state when the bridge body expands.
Furthermore, the bridge body is provided with a railing.
Furthermore, the sliding groove is a rectangular groove, and the protruding block is a rectangular block.
Furthermore, the height of the rectangular block is lower than the depth of the rectangular groove, so that the contact area between the pier and the fixed seat is ensured.
Furthermore, the connecting column is cylindrical.
By adopting the technical scheme, the beneficial effects of the utility model are that: the utility model discloses a be equipped with curved layer board between the adjacent pier of closed bridge, layer board top and bridge body contact are in order upwards to push away the bridge body, provide ascending fulcrum for the middle part of the bridge body between the adjacent pier, avoid leading to the bridge body fracture to collapse because of bridge body tenesmus range is great.
