Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance, in particular to an anti-overturning reinforcement structure for bridge maintenance. Background Art

[0002] Bridges generally refer to structures built on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other traffic needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports and auxiliary structures. In the case of bridge aging, car overload, etc., the bridge deck is very likely to overturn as a whole, causing serious economic and social losses and posing a major safety hazard. Therefore, it is necessary to carry out anti-overturning reinforcement on the built bridges to improve the overall anti-overturning safety factor of the bridge.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN218621899U discloses an anti-overturning reinforcement structure for bridge maintenance, comprising: a bridge deck and a bridge pier, wherein the bridge deck and the bridge pier are connected via a steel structure bearing support A; a reinforcement assembly is installed at the upper position of the outer wall of the bridge pier, wherein the reinforcement assembly is composed of two oppositely arranged reinforcement modules, and the two reinforcement modules are fixed by threads, and the reinforcement module comprises a support beam plate, wherein the top of the support beam plate is connected to the bottom of the bridge deck via a steel structure bearing support B. In this anti-overturning reinforcement structure for bridge maintenance, a steel structure bearing support B is installed between the support beam plate and the bridge deck, and the bridge deck is supported by two steel structure bearing supports B and one steel structure bearing support A, and the certain force of the traditional single pier support is changed to the current three-point force, which expands the support force area, improves the structural force system, improves the support stability, and also increases the anti-overturning effect to ensure driving safety.

[0004] However, the existing anti-overturning reinforcement mechanism for bridge maintenance tightly connects the bridge pier and the hoop plate by pouring concrete blocks, which is not convenient for subsequent dismantling and recycling or maintenance and replacement, and easily causes waste of resources.

[0005] To this end, we propose an anti-overturning reinforcement structure for bridge maintenance to solve the above problems. Utility Model Content

[0008] The bottom surface of the beam body is connected to multiple fixed plates through multiple high-strength bolts. The bottom surface of the fixed plates is fixedly connected to multiple connecting plates. One side of the connecting plates is provided with through holes. The through holes are rotatably connected to fixed shafts.

[0013] Preferably, the second limiting circular plate is rotatably connected to the second connecting plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model strengthens the bridge by arranging structures such as a fixing plate, a high-strength bolt, a connecting plate, a fixing shaft, a fixing plate, a high-strength bolt, a connecting plate, and a fixing shaft, and by adding an anti-pullout device, thereby increasing the support area of ​​the bottom of the beam body and improving the anti-overturning ability of the bridge.
