Description

Technical Field

[0001] This utility model relates to the field of road and bridge crack reinforcement technology, specifically a road and bridge crack reinforcement structure. Background Technology

[0002] As a crucial component of transportation infrastructure, roads and bridges are prone to cracking during long-term use, especially under the influence of thermal expansion and contraction. These cracks not only affect the structural integrity and stability but also pose a potential threat to traffic safety. Existing repair techniques primarily employ concrete filling to address these cracks.

[0003] In practice, if the newly filled repair mortar and bonding material are subjected to repeated vehicle loads during the solidification process, the interface between the filler and the original structure on both sides of the crack may separate, affecting the repair effect. If the filler is subjected to external forces during its curing time, it will affect its curing effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a road and bridge crack reinforcement structure, which solves the problem mentioned in the background art that, during the solidification process of newly filled repair mortar and bonding materials, repeated vehicle loads may cause the interface between the filler and the original structure on both sides of the crack to separate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road and bridge crack reinforcement structure, comprising an upper baffle and a reinforcement mechanism, wherein the reinforcement mechanism is installed in the middle of the crack opening, the crack opening is in the middle of the roadbed, the upper baffle is installed at the upper end of the crack opening, and multiple sets of reinforcement mechanisms are provided at the lower end of the upper baffle, the reinforcement mechanism comprising an upper support column, the upper support column having a sliding opening in the middle, a vertical support column being movably installed inside the sliding opening, the upper end of the vertical support column being connected to the upper baffle, a lower support column being fixed at the lower end of the vertical support column, support strips being movably installed on both sides of the upper support column, a connecting strip being movably connected in the middle of the support strip, the lower end of the connecting strip being connected to the lower support column, and reinforcement holes being obliquely opened on both sides of the crack opening, the lower end of the support strip being inserted into the reinforcement holes.

[0006] Preferably, an installation groove is provided on the roadbed, the installation groove is opened at the upper end of the crack opening, the width of the installation groove corresponds to the upper baffle, and the upper baffle is installed inside the installation groove.

[0007] Preferably, the upper baffle has multiple sets of mounting holes, and the vertical support column is located at the lower end of the mounting holes. The vertical support column is fixed to the upper baffle by a fixing bolt passing through the mounting hole.

[0008] Preferably, both the upper baffle and the reinforcing mechanism are made of metal.

[0009] Preferably, after the reinforcement mechanism is installed, repair mortar is injected into the crack opening.

[0010] This utility model provides a road and bridge crack reinforcement structure with the following beneficial effects: In actual use, when a vehicle load acts on the upper baffle, the downward force will force the vertical support column to move downward, and drive the support strips on both sides of the upper support column to contract downward and towards the middle of the crack through the connecting strip. The lower end of the support strip is inserted into the reinforcement holes on both sides of the roadbed. The support strip not only provides immediate support force when the upper baffle is pressed down, slowing down the movement of the roadbed to both sides, but also effectively reinforces the newly filled repair mortar and adhesive material before they solidify. After the repair material solidifies, the support strip remains in the reinforcement hole and continues to play its fixing role, enhancing the overall stability of the reinforcement structure and the roadbed.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4This utility model provides a technical solution: a road and bridge crack reinforcement structure, including an upper baffle 1 and a reinforcement mechanism 2. The reinforcement mechanism 2 is installed in the middle of the crack opening 31, which is in the middle of the roadbed 3. The upper baffle 1 is installed at the upper end of the crack opening 31. Multiple sets of reinforcement mechanisms 2 are provided at the lower end of the upper baffle 1. The reinforcement mechanism 2 includes an upper support column 21. A sliding opening 211 is opened in the middle of the upper support column 21. A vertical support column 23 is movably installed inside the sliding opening 211. The upper end of the vertical support column 23 is connected to the upper baffle 1. A lower support column 22 is fixed at the lower end of the vertical support column 23. Support bars 24 are movably installed on both sides of the upper support column 21. A connecting bar 25 is movably connected in the middle of the support bar 24. The lower end of the connecting bar 25 is connected to the lower support column 22. Reinforcement holes 32 are opened obliquely on both sides of the crack opening 31. The lower end of the support bar 24 is inserted into the reinforcement hole 32.

[0018] During use, the upper baffle 1, installed at the top of the crack opening 31, provides a support surface for the reinforcement mechanism 2 below. When the vehicle load acts on the upper baffle 1, the vertical support column 23 transmits the pressure to the lower support column 22, and then transmits the force to the roadbed 3 through the support bar 24 and the reinforcement hole 32, pulling it towards the middle and slowing down the movement of the roadbed 3 to both sides. It also effectively reinforces the newly filled repair mortar 4 and the bonding material before they solidify. After the repair material solidifies, the support bar 24 remains in the reinforcement hole 32 and continues to play its fixing role, enhancing the overall stability of the reinforcement structure and the roadbed 3.

[0019] An installation groove 33 is provided on the roadbed 3. The installation groove 33 is located at the upper end of the crack opening 31. The width of the installation groove 33 corresponds to that of the upper baffle 1. The upper baffle 1 is installed inside the installation groove 33. By using the installation groove 33, which corresponds to the width of the upper baffle 1, it can be ensured that the upper baffle 1 will not shake or shift during installation, thereby improving the stability and reliability of the reinforcement structure.

[0020] The upper baffle 1 has multiple sets of mounting holes 11. The vertical support column 23 is set at the lower end of the mounting hole 11. The vertical support column 23 is fixed to the upper baffle 1 by passing through the mounting hole 11 with fixing bolts 26. The design of the mounting hole 11 also facilitates the insertion and tightening of the fixing bolts 26, so that the vertical support column 23 can be firmly fixed on the upper baffle 1, and the upper baffle 1 can be easily disassembled after solidification.

[0021] Both the upper baffle 1 and the reinforcement mechanism 2 are made of metal. The metal material enhances the overall stability and load-bearing capacity of the reinforcement structure, thereby improving the quality and effect of crack repair.

[0022] After the reinforcement mechanism 2 is installed, repair mortar 4 is injected into the crack opening 31. The main function of injecting repair mortar 4 into the crack opening 31 is to fill the crack and repair the damage. It also works together with the reinforcement mechanism 2 to enhance the stability and load-bearing capacity of the crack opening 31.

[0023] As an embodiment of this utility model: when using the road and bridge crack reinforcement structure, when the vehicle load acts on the upper baffle 1, the downward force will force the vertical support column 23 to move downward, and drive the support strips 24 on both sides of the upper support column 21 to contract downward and towards the middle of the crack through the connecting strip 25. The lower end of the support strip 24 is inserted into the reinforcement holes 32 on both sides of the roadbed 3. The support strip 24 not only provides immediate support force when the upper baffle 1 is pressed down, slowing down the movement of the roadbed 3 to both sides, but also effectively reinforces the newly filled repair mortar 4 and the bonding material before they solidify. After the repair material solidifies, the support strip 24 remains in the reinforcement hole 32 and continues to play its fixing role, enhancing the overall stability of the reinforcement structure and the roadbed 3. After solidification, the upper baffle 1 can be removed by fixing bolts 26; thus completing the use of the road and bridge crack reinforcement structure.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
