Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge, and more specifically, it relates to a reinforcement structure for cracks in road and bridge. Background Art

[0002] In the existing technology, the reinforcement structures for cracks in road and bridges often have problems with poor reinforcement effects. These problems may stem from various factors, including the selection of reinforcement materials, the application methods of reinforcement technologies, and the overall design of the reinforcement structure. For example, traditional crack filling materials may not have sufficient strength and durability, resulting in a non - lasting reinforcement effect, or the design of the reinforcement layer may not fully consider the actual load - bearing requirements of the bridge, thus affecting the reinforcement effect. In addition, the reinforcement structures in the existing technology may lack flexibility and are difficult to adapt to the changes of the bridge under different environments and usage conditions, thereby affecting the long - term and stability of the reinforcement effect.

[0003] The reinforcement structures in the existing technology are inconvenient in terms of quick clamping and quick disassembly. This may be because the fixing methods of the reinforcement structures are relatively complex, requiring more time and labor to complete the installation and disassembly processes. For example, the existing anchor fittings may require special tools and skills for correct installation, and may cause secondary damage to the bridge structure during disassembly. This inconvenience not only prolongs the construction period, increases the maintenance cost, but also may affect the normal use of the bridge, especially when urgent repair or replacement of the reinforcement structure is needed. Therefore, the deficiencies of the reinforcement structures in the existing technology in terms of quick clamping and quick disassembly have become important limiting factors for improving the reinforcement efficiency of road and bridge cracks and reducing the maintenance cost.

At the same time, insert the mounting holes 6 provided at the four corners of the fixing plate 4 into the multiple clamping rods 7, then insert the clamping rods 7 into the clamping sleeves 9, align the limiting grooves 18 provided on the clamping rods 7 with the limiting strips 17 provided on the clamping sleeves 9, slide the unlocking sleeve 19 upward to abut against multiple pressure plates 13, so that the multiple pressure plates 13 release the downward pressure on the clamping blocks 10, so that the multiple tension springs 16 pull the multiple clamping blocks 10 to move into the storage grooves 15.

The roadbed 1 is reinforced by multiple groups of reinforcement bars 2.

[0036] Please refer to Figure 5 , as an implementation manner of the unlocking mechanism: an unlocking mechanism is provided on the clamping sleeve 9. The unlocking mechanism includes an unlocking sleeve 19, a sliding sleeve 20, a tension spring 21, a limiting block 22, a limiting hole 23, a rotating sleeve 24 and an arc-shaped rod 25.

Multiple groups of limiting blocks 22 are installed on the sliding sleeve 20. Limiting holes 23 are provided on the multiple groups of limiting blocks 22. The rotating sleeve 24 is rotatably installed at the top of the clamping sleeve 9. Multiple groups of arc-shaped rods 25 are installed on the outer wall of the rotating sleeve 24.

[0037] The multiple groups of limiting holes 23 are all set to be adapted to the multiple groups of arc-shaped rods 25 and can be slidably connected.

[0038] More specifically, when it is necessary to disassemble the fixed plate 4, pull the sliding sleeve 20 upward to drive the unlocking sleeve 19 to slide along the clamping sleeve 9, so that the top end of the unlocking sleeve 19 abuts against multiple pressing plates 13, causing one end of the multiple pressing plates 13 to rise, releasing the downward pressure on the multiple pressing rods 12, so that the multiple tension springs 16 pull the multiple clamping blocks 10 to move into the storage groove 15.

Then insert the clamping rod 7 into the clamping sleeve 9. When the clamping groove 8 moves to the inner side of the multiple clamping blocks 10, loosen the unlocking sleeve 19, so that the multiple tension springs 21 pull the sliding sleeve 20 to drive the unlocking sleeve 19 to release the abutment against the multiple pressing plates 13, so that the multiple compression springs 14 pull the multiple pressing plates 13 to press the multiple pressing rods 12, so that the multiple pressing rods 12 slide along the clamping sleeve 9 to push the clamping blocks 10 to be clamped in the clamping groove 8, and the quick clamping of the fixed plate 4 can be completed, and the quick installation of the reinforcement mechanism can be completed, and the roadbed 1 can be reinforced by the multiple reinforcement bars 2.

[0040] When it is necessary to disassemble the fixed plate 4, pull the sliding sleeve 20 upward to drive the unlocking sleeve 19 to slide along the clamping sleeve 9, so that the top end of the unlocking sleeve 19 abuts against multiple pressing plates 13, causing one end of the multiple pressing plates 13 to rise, releasing the downward pressure on the multiple pressing rods 12, so that the multiple tension springs 16 pull the multiple clamping blocks 10 to move into the storage groove 15. After the sliding sleeve 20 drives the multiple limiting blocks 22 to rise to the position of the rotating sleeve 24, rotate the rotating sleeve 24, so that the rotating sleeve 24 drives the multiple arc-shaped rods 25 to rotate, and insert the multiple arc-shaped rods 25 into the limiting holes 23 provided on the multiple limiting blocks 22, then the position of the sliding sleeve 20 can be fixed, making it impossible for the multiple tension springs 21 to pull the sliding sleeve 20 to reset.
