Abstract
Description
A road and bridge crack repair and fixing structure Technical Field
[0001] This utility model relates to the field of road and bridge maintenance technology, specifically to a road and bridge crack repair and fixing structure. Background Technology
[0002] With the continuous increase in traffic flow and the influence of natural environmental factors, road bridges are prone to cracks during long-term use. These cracks not only affect the aesthetics of the bridge, but may also lead to a decrease in the structural strength of the bridge, or even cause safety accidents.
[0003] Currently, existing methods for repairing road and bridge cracks typically involve simply filling the cracks with filling materials. While this method can repair cracks to some extent, it is not very resistant to changes in crack width or external environmental erosion. It cannot achieve long-term effective reinforcement and protection, and the repair effect is not sustainable. Frequent maintenance is required, which increases maintenance costs and workload.
[0004] Therefore, it is necessary to propose a road and bridge crack repair and fixing structure. Summary of the Invention
[0005] In view of the shortcomings of the prior art, this utility model provides a road and bridge crack repair and fixing structure, which has the advantages of long-term effective repair and reinforcement of cracks, improving the stability and durability of bridge structure, and solving the problems mentioned in the background art.
[0006] This utility model provides the following technical solution: a road and bridge crack repair and fixing structure, comprising fixing component one and fixing component two:
[0007] The fixing component one and fixing component two have the same structure, and the fixing component one includes a reinforcing plate one and a reinforcing plate two.
[0008] The lower surfaces of the first and second reinforcing plates are provided with side grooves. The side of the first reinforcing plate is provided with a U-shaped groove. The side of the second reinforcing plate is fixedly connected with a U-shaped connecting block. The U-shaped connecting block is inserted into the inside of the U-shaped groove. The side of the overlapping part of the first and second reinforcing plates is provided with a through filling port.
[0009] Preferably, both outer ends of the first reinforcing plate and the second reinforcing plate are fixedly connected to mounting blocks, and the mounting blocks are internally threaded with bolts.
[0010] Preferably, a mating groove is provided on one side of the upper surface of the first reinforcing plate and the second reinforcing plate, and a mating block is fixedly connected to the other side of the upper surface of the first reinforcing plate and the second reinforcing plate, and the mating block is mated with the inside of the mating groove.
[0011] Preferably, the docking groove has a second connection port inside, the docking block has a first connection port, and the second connection port and the first connection port are internally threaded with a second bolt.
[0012] Preferably, a sealing strip is adhered to the lower surface edge of the first reinforcing plate and the second reinforcing plate, and the sealing strip is made of nitrile rubber.
[0013] Preferably, the side grooves on the first reinforcing plate and the side grooves on the second reinforcing plate have the same internal size and are interconnected.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This type of road and bridge crack repair and fixing structure consists of two fixing components, Fixing Component 1 and Fixing Component 2, which have identical structures. During repair and fixing, Fixing Component 1 and Fixing Component 2 are placed at the crack via a U-shaped groove and a U-shaped connecting block. Fixing Component 1 and Fixing Component 2 are then fixed to the bridge using mounting blocks and bolts. A specific amount of epoxy resin filler is injected into the opposing side grooves of Fixing Component 1 and Fixing Component 2 through injection ports on their sides, filling the crack and the interior of the side grooves. Depending on the crack length, Fixing Component 1 and multiple sets of Fixing Component 2 can be used together. Fixing Component 2 and Fixing Component 1 are connected by... The connecting block, connector two, and bolt two are assembled to completely cover the gap. This structure allows epoxy resin material to be filled into the crack, effectively repairing it and enhancing its structural strength. Reinforcing plate one and reinforcing plate two are fixed to the bridge structure with connecting bolts, and the epoxy resin material further strengthens the connection between reinforcing plate one and reinforcing plate two and the bridge structure. This reinforces the bridge structure on both sides of the crack, improving the overall stability and load-bearing capacity of the bridge and effectively resisting the effects of changes in crack width. Sealing strips are installed at the connection edges of reinforcing plate one and reinforcing plate two and the bridge structure to enhance the sealing of the connection and improve resistance to external factors.
