Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, in particular to a reinforcement support for road and bridge construction. Background Art

[0002] Reinforced bearings for road and bridge construction refer to supporting components used in bridge engineering to enhance or repair the bearing capacity and stability of existing bridge structures. Such bearings play a key role in the process of bridge reinforcement and reconstruction. Their main functions include transferring the load of the bridge superstructure to the substructure and ensuring the free deformation of the bridge under various stress states, while also being able to adapt to displacement caused by factors such as temperature changes and concrete shrinkage creep.

[0003] In the prior art, during the installation of reinforced bearings, they are usually positioned, drilled, and installed inside the road bridge. The embedded parts are tightly combined with the concrete structure, and then the reinforced bearing body is connected to the embedded sleeve by anchor bolts for installation. Although this meets the use requirements to a certain extent, in actual use, when fixing with anchor screws, high assembly accuracy is required, otherwise the functional performance of the bearing may be affected. If the hole position is inaccurate or the bolt length is inappropriate, the reliability of the connection will be reduced. To ensure the installation accuracy, each step requires refined operation, and repeated adjustments and verifications may be required, which will lead to a longer construction period. Utility Model Content

[0004] The utility model aims to provide a reinforcement support for road and bridge construction, which has the advantages of low assembly precision requirements without the need for a perfect fit of the connection mechanism, thereby solving the problems of high assembly precision requirements and long construction period.

[0007] As a preferred reinforcement support for road and bridge construction of the utility model, a plurality of conduits are fixedly installed on the top of the connecting plate, and a one-way valve is fixedly installed on the top of the connecting plate.

[0008] As a preferred reinforcement support for road and bridge construction of the utility model, the seismic isolation mechanism includes two groups of mounting plates, and the seismic isolation mechanism also includes a plurality of rubber plates and steel plates, and the rubber plates and steel plates are staggeredly installed inside the two groups of mounting plates.

[0009] As a preferred reinforcement support for road and bridge construction of the utility model, the outer walls of the rubber plate and the steel plate are fixedly installed with a fireproof layer.

[0010] As a preferred reinforcement support for road and bridge construction of the utility model, a plurality of memory metal columns are fixedly installed inside the rubber plate and the steel plate.

[0011] As a preferred reinforcement support for road and bridge construction of the utility model, a plurality of sealing shells are fixedly installed on the top of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model squeezes the movable ring through the spring, so that the squeezing ring squeezes the fixed ball to one side of the mounting pin, and then the mounting pin is fixed inside the mounting seat through the cooperation between the locking groove and the fixed ball. When unlocking is required, it is only necessary to inflate the gap between the movable ring and the cover plate through the air inlet hole to push the movable ring to move downward to complete the unlocking. This device does not need to fit tightly with the mounting hole like a fastening bolt, and is fixed by elastic squeezing of the fixed ball. When a small offset occurs, the fixed connection can still be completed, and the precision requirement is low, which solves the problems of high assembly precision requirements and long construction period.

[0020] During use, after the seismic isolation mechanism 2 is installed inside the bridge component, the mounting pin 305 is positioned and installed at the bottom of the embedded mechanism 1, and then the mounting pin 305 is inserted into the inside of the mounting seat 301. During this process, the movable ring 303 is squeezed by the spring 302, and then the extrusion ring 306 squeezes the fixed ball 307 to one side of the mounting pin 305, and then the mounting pin 305 is fixed inside the mounting seat 301 through the cooperation between the locking groove 308 and the fixed ball 307. When unlocking is required, it is only necessary to inflate the gap between the movable ring 303 and the cover plate 304 through the air inlet hole 309 to push the movable ring 303 to move downward to complete the unlocking. This device does not need to fit tightly with the mounting hole like a fastening bolt, and is fixed by the elastic extrusion of the fixed ball 307. The fixed connection can still be completed when a small offset occurs, and the precision requirement is low, which solves the problems of high assembly precision requirements and long construction period.

[0021] Furthermore, the embedded mechanism 1 includes a connecting plate 101, and a plurality of anchoring structures 102 are fixedly installed at the bottom of the connecting plate 101;

[0022] During use, the anchor structure 102 penetrates into the concrete to form a reliable anchoring force, ensuring that the embedded mechanism 1 remains stable in the structure, and the connection plate 101 is exposed to the outside to serve as an installation platform.

[0023] Furthermore, a plurality of conduits 103 are fixedly installed on the top of the connecting plate 101, and a one-way valve 104 is fixedly installed on the top of the connecting plate 101;

[0025] Furthermore, the seismic isolation mechanism 2 includes two sets of mounting plates 201, and the seismic isolation mechanism 2 also includes a plurality of rubber plates 202 and steel plates 203, and the rubber plates 202 and steel plates 203 are staggeredly installed inside the two sets of mounting plates 201;

[0026] During use, the rubber plates 202 are used to allow the two groups of seismic isolation mechanisms 2 to undergo large shear deformation, allowing the beam body to freely translate within a certain range, thereby adapting to the horizontal displacement requirements of the bridge. By staggeredly installing steel plates 203 inside several rubber plates 202, the seismic isolation mechanism 2 is structurally reinforced to improve the compressive performance of the bearing when bearing vertical loads, ensuring that the bearing can reliably transfer the gravity load of the bridge superstructure to the lower structure.

[0029] Furthermore, a plurality of memory metal columns 204 are fixedly installed inside the rubber plate 202 and the steel plate 203;

[0030] During use, the material characteristics of the memory metal column 204 enable the seismic isolation mechanism 2 to automatically restore to its initial state, thereby reducing permanent deformation caused by long-term stress accumulation.

[0031] Furthermore, a plurality of sealing shells 206 are fixedly mounted on the top of the mounting plate 201;

[0032] During use, the connection mechanism 3 is covered by the sealing shell 206 to prevent the connection mechanism 3 from being exposed to the outside and being affected by wind and rain, salt spray, chemicals, etc., so as to prevent rust and loss of connection function.
