Description

Technical Field

[0001] This utility model relates to the field of bridge expansion joint technology, specifically to a bridge expansion joint repair and reinforcement hanger. Background Technology

[0002] Bridge expansion joints are expansion devices installed between two beam ends, between a beam end and an abutment, or at the hinged joints of a bridge to accommodate the deformation of the bridge deck and adjust the displacement and connection between the superstructure caused by vehicle loads and bridge construction materials. However, due to long-term use or overloaded vehicles, bridge expansion joints may suffer varying degrees of damage, thus requiring timely repair and maintenance.

[0003] Publication No. CN214530251U discloses a BIM-based bridge expansion joint reinforcement device, comprising a first reinforcement plate, a second reinforcement plate, a first groove, and a second groove. The second reinforcement plate is disposed on one side of the first reinforcement plate. The first groove is disposed between the first and second reinforcement plates. The second groove is disposed at the connection point between the second reinforcement plate and the first groove. Connecting blocks are disposed on the outer walls of both the first and second reinforcement plates, and a sliding element is disposed at one end of each connecting block. The beneficial effect is that, through the design of the connecting block, sliding block, and spring, this invention enables the expansion joint reinforcement device to have a rapid recovery function, allowing it to quickly recover when the expansion joint is subjected to various pressures, thereby reducing the wear and tear on the expansion joint.

[0004] While existing technologies have solved the problem of loosening, the large gaps between expansion joints make them prone to accumulating debris over time, thus affecting the expansion effect. Therefore, a bridge expansion joint repair and reinforcement hanger is proposed, which uses a deformable structure to fill the gaps between reinforcement structures to avoid affecting the expansion effect due to the accumulation of debris. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a bridge expansion joint repair and reinforcement hanger, which uses a deformable structure to fill the gaps between reinforcement structures, so as to avoid affecting the expansion effect due to the filling of a large amount of debris.

[0006] The technical solution adopted by this utility model to solve its technical problem is a bridge expansion joint repair and reinforcement hanger, including a first reinforcement frame, a second reinforcement frame and an expansion joint. Each of the first reinforcement frame and the second reinforcement frame is provided with a support component on one side, and an expansion frame is sleeved on one end of each support component. The first reinforcement frame has a first tooth body evenly arranged from top to bottom on one side surface, and the second reinforcement frame has a second tooth body arranged alternately with the first tooth body on one side. The expansion joint is provided with an elastic body.

[0007] By adopting the above technical solution, the shock-absorbing spring on the inner wall of the support component is used in conjunction with the telescopic frame's telescopic movement, and the telescopic frame is smoothly extended and retracted through the slide rail on the inner wall of the support component. The first and second tooth bodies are supported and fixed by the first and second reinforcing frames respectively, and the expansion joint between the first and second tooth bodies allows for their free expansion and contraction. The expansion joint is filled with an elastomer. It has a certain degree of hardness and is more wear-resistant than rubber materials. Its ultra-high elasticity allows it to deform freely during expansion and contraction, and avoids affecting the expansion and contraction effect due to the filling of a large amount of debris. The fixed support blocks are fixed to both sides of the elastic body, and one end of the fixed support block is bolted to the inner wall of the first and second reinforcement frames, and the other end of the fixed support block is bolted to one end of the first and second toothed bodies, so as to improve the convenience of later disassembly and replacement.

[0008] Specifically, the first reinforcement frame and the second reinforcement frame are positioned opposite each other.

[0009] By adopting the above technical solution, the first and second reinforcing frames are used to support and fix the first tooth body and the second tooth body respectively.

[0010] Specifically, one end of the telescopic frame is located at the bottom of the support component and is fixed with a shock-absorbing spring by a support block.

[0011] By adopting the above technical solution, the shock-absorbing springs on the inner wall of the support component are used in conjunction with the telescopic movement of the telescopic frame.

[0012] Specifically, slide rails are installed on both sides of the inner wall of the support component, and the telescopic frame is slidably connected to the slide rails through sliders on both sides.

[0013] By adopting the above technical solution, the sliding rails on the inner wall of the support component are used in conjunction with the telescopic frame to ensure smooth extension and retraction.

[0014] Specifically, the expansion joint is located between the inner walls of the first tooth body and the second reinforcing frame, and between the inner walls of the second tooth body and the first reinforcing frame.

[0015] By adopting the above technical solution, the expansion joint between the first tooth body and the second tooth body is used to allow for their free expansion and contraction.

[0016] Specifically, fixed supports are provided on both sides of the elastic body. One end of the fixed support is installed on the inner wall of the first and second reinforcing frames by bolts, and the other end of the fixed support is installed on one end of the first and second toothed bodies by bolts.

[0017] By adopting the above technical solution, a fixed support block is used to fix the elastic body on both sides. One end of the fixed support block is installed on the inner wall of the first and second reinforcing frames by bolts, and the other end of the fixed support block is installed on one end of the first and second toothed bodies by bolts, so as to improve the convenience of subsequent disassembly and replacement.

[0018] The beneficial effects of this utility model are: (1) The bridge expansion joint repair and reinforcement hanger described in this utility model uses an elastic body to fill the expansion joint position. It has a certain hardness and is more wear-resistant than rubber materials. It also has ultra-high elasticity to cooperate with the free deformation of expansion and contraction movement, and avoids the expansion and contraction effect being affected by filling a large amount of debris.

[0019] (2) The bridge expansion joint repair and reinforcement hanger of this utility model is fixed to both sides of the elastic body by a fixed support block, and one end of the fixed support block is installed on the inner wall of the first reinforcement frame and the second reinforcement frame by bolts, and the other end of the fixed support block is installed on one end of the first tooth body and the second tooth body by bolts, so as to improve the convenience of later disassembly and replacement.
