Description

Technical Field

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

[0002] At present, there are still some defects and shortcomings in the use of road and bridge crack reinforcement structures. The specific areas that need improvement are as follows: 1. The existing road and bridge crack reinforcement work is mainly divided into two methods: casting reinforcement and steel structure reinforcement, but the two cannot be used in combination with each other, and there are certain limitations in use; 2. In the traditional reinforcement method, the reinforcement plate is directly fixed on the crack. Due to the back and forth driving of multiple vehicles, the compression and shock absorption effect is poor, and cracks are still prone to appear over time; therefore, we have introduced a new road and bridge crack reinforcement structure. Utility Model Content

[0003] The main purpose of the utility model is to provide a road bridge crack reinforcement structure, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The reinforcement device includes a long screw rod, two of which are provided, the lower ends of the two long screw rods are fixedly connected to a chassis, a plurality of auxiliary drill bits are fixedly connected around the lower end of the chassis, a ground anchor rod is fixedly connected to the middle part of the upper end of the chassis, a connecting column is fixedly connected to the middle part of the upper end of the ground anchor rod, the upper part of the outer surface of the long screw rod is threadedly connected to a fixing bolt, and the long screw rods are respectively installed in the mounting holes.

[0007] Preferably, the buffer device includes an insert rod, a plurality of threads are engraved on the upper outer surface of the insert rod, a shock absorbing spring is sleeved on the middle outer surface of the insert rod, a casting groove is opened at the upper end of the insert rod, and the insert rod is fixedly mounted on the lower end of the positioning plate.

[0008] By adopting the above technical solution: through the shock-absorbing springs on the plug rods, the vibration and impact force generated when the bridge is subjected to vehicle loads and natural vibration external forces can be effectively absorbed and alleviated.

[0009] Preferably, there are several auxiliary drill bits, which are evenly distributed in a ring shape at the lower end of the chassis.

[0010] By adopting the above technical solution, the annular uniform distribution of the auxiliary drill bits makes the reinforcement device more stable when drilling into the foundation, and the force is more evenly applied, thereby improving the installation efficiency and stability of the reinforcement device.

[0011] Preferably, the positional dimensions of the two long screws are matched one by one with the positional dimensions of the two fixing bolts, and the two long screws are inserted through the positioning plates and fixedly installed in the mounting holes respectively.

[0012] By adopting the above technical solution: it is possible to ensure that the connection between the reinforcement device and the positioning plate is tighter and more stable, and prevent loosening and displacement. This tight connection method enhances the supporting effect of the reinforcement device on the bridge.

[0013] Preferably, the casting trough is communicated with the interior of the casting hole.

[0014] By adopting the above technical solution: the casting trough is communicated with the inside of the casting hole, so that when pouring concrete, the concrete can fill the entire reinforced structure and form a tighter structure.

[0015] Preferably, the insertion rod has a conical structure.

[0016] By adopting the above technical solution: the conical structure of the insertion rod has better guidance and stability when inserted into the foundation, can more easily penetrate the soil layer, reduce the construction difficulty and time, and this structure enables the buffer device to be quickly and accurately installed at the lower end of the positioning plate, thereby improving construction efficiency.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. In the utility model, the long screw rod passes through the installation hole, and the chassis is anchored to the bridge plate through the auxiliary drill bit at its lower end. The ground anchor rod further enhances the stability of the connection with the bridge plate. The connecting column plays an auxiliary connection role, and the fixing bolt fastens the long screw rod in the installation hole to ensure that the reinforcement device is firmly installed. It can ensure that the connection between the reinforcement device and the positioning plate is tighter and more stable, and prevents loosening and displacement. This tight connection method enhances the supporting effect of the reinforcement device on the bridge, improves the stability and safety of the bridge, and adopts a combination of casting reinforcement and steel structure reinforcement to effectively reinforce and repair cracks on the bridge plate and extend the service life of the bridge.

[0019] 2. In the utility model, the rod is stably connected to the positioning plate through the thread on its outer surface. The shock-absorbing spring can play a role in buffering and shock-absorbing when the bridge plate is vibrated or impacted, thereby reducing the adverse effects on the structure. The buffering effect of the shock-absorbing spring can extend the service life of the bridge and improve driving safety and comfort. BRIEF DESCRIPTION OF THE DRAWINGS
