Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge repair, in particular to a road and bridge crack repair fixing structure. Background Art

[0002] Roads and bridges are generally composed of several parts, including roadbed, pavement, bridges, tunnel engineering and traffic engineering facilities;

[0003] When a road bridge is damaged, it needs to be repaired. When cracks appear on the bridge, in order to prevent the cracks from further increasing, the cracks need to be repaired. At present, in the process of repairing bridge cracks, a repair agent is often injected into the bridge cracks to achieve repair and enhancement. However, the reinforcement effect is generally general when the repair agent is used alone, and it does not have the function of reinforcing the crack structure, so the service life after repair is short and further damage will still occur. Therefore, we propose a road bridge crack repair fixed structure. Utility Model Content

[0004] The purpose of the utility model is to provide a road bridge crack repair fixing structure, which solves the problems raised in the background technology.

At the same time, the first reinforcement rod, the second reinforcement rod and the third reinforcement rod are hinged, so that the device can have a bending function, so that it can adapt to the curved surface of the bridge base for reinforcement, and the adaptability of the device is improved.

[0007] As a preferred embodiment of the utility model, the positioning pin includes a pin shaft and an end block, a bolt column is fixed to the outer end of the pin shaft, a threaded groove is provided on one side wall of the end block, and the pin shaft movably passes through the through holes provided on the outer walls of the first reinforcement rod and the second reinforcement rod and engages with the threaded groove on the end block.

[0008] By adopting the above technical solution, the first reinforcement rod and the second reinforcement rod can be connected in a limited position by using the pin shaft and the end block connection, and the first reinforcement rod and the second reinforcement rod can be rotated, while the positioning pin is removable, thereby facilitating the addition and removal of the first reinforcement rod and the second reinforcement rod to meet the reinforcement requirements of different widths.

[0009] As a preferred embodiment of the present utility model, one end surface of the pin shaft and one end surface of the end block are both provided with a hexagonal groove.

[0010] By adopting the above technical solution, the setting of the hexagonal groove makes it convenient to operate the pin shaft and the end block with the help of a hexagonal wrench, thereby facilitating disassembly and assembly.

[0011] As a preferred embodiment of the present utility model, the outer walls of the first reinforcement rod and the second reinforcement rod are provided with a plurality of evenly distributed circular holes.

[0012] By adopting the above technical solution and setting the circular hole, after filling the repair agent, the contact area between the device and the repair agent can be increased, thereby improving the stability after bonding, and further improving the repair and reinforcement effect.

[0013] As a preferred embodiment of the present invention, a nut is fixedly welded to the outer wall of the screw, and a plurality of evenly distributed holes are formed on the outer wall of the nut.

[0014] By adopting the above technical solution, the setting of the nut and the hole makes it convenient to insert the nut into the hole with the help of a corresponding tool and then rotate the nut, thereby facilitating the rotation of the screw rod and improving the convenience of operation.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The technical solution of the present application is a road bridge crack repair fixing structure, which has embedded grooves on both sides of the crack, embeds the device in the embedded grooves, uses a stabilizing pile to penetrate the through hole and insert it into the road surface, and then rotates the bolt to pull the two ends, so that the two sides of the crack can be pulled, thereby strengthening, and then repairing with a repair agent can significantly improve the stability of the crack after repair, thereby extending the service life after repair;

[0018] The outer walls of the first reinforcement rod and the second reinforcement rod are both provided with a plurality of evenly distributed circular holes, so that when the repair agent is filled, the contact area between the device and the repair agent can be increased, thereby improving the stability of the repair agent adhesion, and further improving the stability of the repair;

[0031] Furthermore, the outer walls of the first reinforcement rod 1 and the second reinforcement rod 11 are provided with a plurality of evenly distributed circular holes. The arrangement of the circular holes can increase the contact area between the device and the repair agent after filling the repair agent, thereby improving the stability after bonding, and further improving the repair and reinforcement effect;
