Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a reinforcement device for cracked concrete. Background Art

[0002] With the economic development of western my country, more and more bridges are being built in high-altitude and cold regions. However, in such an environment, the problem of concrete cracks in bridge piers is becoming increasingly prominent. In high-altitude and cold regions, the temperature difference between day and night is large, and the temperature changes are more drastic. The concrete of bridge piers is greatly affected by thermal expansion and contraction, which easily leads to cracks.

[0003] The prior art usually uses a nailing method to fix the concrete cracks of bridge piers. A relatively thin and long metal "sewing U-shaped nail" is used to cross the crack and embed it into a pre-opened groove, and then fixed with non-shrinkage mortar or epoxy resin-based adhesive. Although this method can play a certain role, the effect is not good and the operation is relatively cumbersome.

[0004] Therefore, it is necessary to develop a reinforcement device for concrete cracking to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to design a reinforcement device for cracked concrete in order to solve the above problems.

[0007] Specifically, an adjusting rod and a sliding rod are installed on the second mounting plate perpendicular to the outer side surface, and mounting holes are set at corresponding positions on the adjusting plate. The mounting holes on the adjusting plate are sleeved on the adjusting rod and the sliding rod, the sliding rod is guided by a mounting hole, and a nut is threadedly engaged with the threaded section on the outer end of the adjusting rod extending out of a mounting hole.

[0008] Furthermore, the first end of the connecting plate is formed as a wedge-shaped block 1, and a wedge-shaped block 2 is formed on the adjusting plate, and the inclined surfaces of the wedge-shaped block 1 and the wedge-shaped block 2 are matched.

[0009] Furthermore, a support portion protruding outward is provided on the inner side of the connecting plate, and the lower end of the protection plate is placed on the support portion.

[0010] Furthermore, a through hole is provided at the upper end of the protection plate.

[0011] Preferably, the through hole is arranged in the middle of the upper end of the protection plate.

[0012] Specifically, the second end of the connecting plate is a clamping block, and an inner chamfer is arranged at the inner corner of the clamping block.

[0013] Preferably, the clamping block is perpendicular to the wedge block.
