Description

Technical Field

[0001] The present application belongs to the technical field of bridge crack reinforcement, and specifically relates to a road bridge crack reinforcement device. Background Art

[0002] Road and bridge cracks refer to the discontinuity phenomenon that occurs in road or bridge structures, which usually manifests as cracks in material layers or within the structure. These cracks may be caused by a variety of reasons, including material aging, environmental factors, construction defects, excessive loads, etc. The existence of cracks may have adverse effects on the structural safety, performance and durability of roads or bridges. The road and bridge crack reinforcement device is an important device designed to improve the stability and durability of road and bridge structures. Its main purpose is to repair and strengthen existing cracks to prevent potential damage and safety risks.

[0003] For example, the utility model patent with the announcement number CN221460971U discloses a bridge road crack reinforcement device, which includes a mounting plate, threaded holes and expansion bolts. The mounting plate surface is symmetrically provided with threaded holes, and the four threaded holes are threadedly connected with expansion bolts. This bridge road crack reinforcement device is connected by a bottom fixed bearing to cooperate with a rotating connecting column. The rotation of the connecting column drives the first gear and the second gear to rotate respectively and cooperate with the fixing rod to play a fixed installation on both sides of the bridge road crack to enhance the toughness effect. The threaded holes and expansion bolts are connected to fix the two ends of the bridge road fracture and play a suture connection role by cooperating with the mounting plate. After the insertion is completed, the mounting plate will cover the bridge road crack to completely fix the bridge road, which is more convenient for the subsequent injection of adhesive and the anti-overflow effect.

[0004] However, in actual use, it was found that the cement slurry of the device was discharged through the outlets on the left and right sides of the storage tank to form agglomerates, thereby reinforcing the cracks in the bridge.

[0005] Then, since the liquid outlet is only arranged on the left and right sides of the storage box, when the front or rear side of the storage box is close to the bridge crack, the slurry discharged from both sides cannot fill the cracks on the front and rear sides well, resulting in the slurry filling being not uniform. In addition, the bottom of the mounting plate lacks sufficient sealing. When cement slurry with a certain pressure passes through the bridge crack, part of the slurry may overflow from the gap between the mounting plate and the road surface under the action of pressure, affecting the reinforcement effect of the slurry on the bridge crack. For this purpose, a road bridge crack reinforcement device is provided. Utility Model Content

[0006] The purpose of this application is to provide a road bridge crack reinforcement device in order to solve the above-mentioned problems.

[0007] The technical solution adopted in this application is as follows: A road bridge crack reinforcement device includes a mounting base plate, a plurality of reinforcement cylinders movably provided on the top surface of the mounting base plate, a circular ring fixedly provided on the outer surface of the reinforcement cylinder, an annular magnetic sheet corresponding to the circular ring fixedly provided on the bottom surface of the mounting base plate, the circular ring and the annular magnetic sheet are adsorbed, a plurality of grouting holes are provided in a circular array near the outer surface of the bottom of the reinforcement cylinder, a rectangular sealing gasket is fixedly provided on the bottom surface of the mounting base plate, and a reinforcement mechanism is provided on the outer surface of the reinforcement cylinder.

[0008] In a preferred embodiment, the reinforcement mechanism includes a pushing rod, a reinforcement head, an internal threaded column, a screw, and a circular pushing block. The outer surface of the reinforcement cylinder is movably sleeved with multiple pushing rods, and one side of each of the pushing rods is fixedly installed with a reinforcement head. The top surface of the reinforcement cylinder is penetrated and fixedly installed with an internal threaded column, the internal thread of the internal threaded column is connected to a screw, and the bottom surface of the screw is fixedly installed with a circular pushing block.

[0009] In a preferred embodiment, a plurality of fixing holes are formed in an array at equal intervals on the top surface of the mounting base plate.

[0010] In a preferred embodiment, a grouting connection hole is opened on the top surface of the reinforcement tube.

[0011] In a preferred embodiment, a hexagonal end is fixedly mounted on the top end of the screw.

[0012] In a preferred embodiment, the reinforcement head is made of high carbon steel.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In the present application, due to the adoption of the above-mentioned scheme, the user first connects the sleeve or handle to the hexagonal end head, and then starts to turn the screw. As the screw rotates, the circular pushing block will move downward. Due to its arc-shaped bottom structure, when it contacts the top of the pushing connecting rod, it will push the pushing connecting rod and the reinforcement head forward. In this way, the reinforcement head can be smoothly inserted into the side wall of the crack, thereby enhancing the connection strength between the reinforcement tube and the crack. Then, the personnel connects the external grouting pipe to the grouting connection hole, and allows the slurry with a certain pressure from the outside to enter the interior of the reinforcement tube. These slurries will be evenly discharged through multiple grouting holes to ensure that the inside of the crack can be evenly filled with slurry. This device not only improves the connection strength between the reinforcement tube and the crack, but also makes the filling of the slurry more uniform and efficient. The overall structure is compact and the cost is low, which greatly improves the convenience and efficiency of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] refer to Figure 2 、 Figure 3A plurality of grouting holes 5 are provided in a circular array near the outer surface of the bottom of the reinforcement tube 2, a rectangular sealing gasket 6 is fixedly installed on the bottom surface of the mounting base 1, and a reinforcement mechanism 7 is provided on the outer surface of the reinforcement tube 2; through the provision of the plurality of grouting holes 5, the slurry entering the interior of the reinforcement tube 2 is easily discharged in multiple directions, thereby improving the uniformity of the slurry during grouting.

[0024] refer to Figure 2 、 Figure 3 The reinforcement mechanism 7 includes a pushing rod 8, a reinforcement head 9, an internal threaded column 10, a screw 11, and a circular pushing block 12. The outer surface of the reinforcement tube 2 is movably sleeved with multiple pushing rods 8, and a reinforcement head 9 is fixedly installed on one side of the multiple pushing rods 8. The reinforcement head 9 is made of high-carbon steel material; by setting up multiple pushing rods 8, it is convenient to install and fix the reinforcement head 9. By setting up the reinforcement head 9 made of high-carbon steel material, the strength of the reinforcement head 9 can be improved, which is convenient for the subsequent reinforcement head 9 to be inserted into the crack side wall of the bridge.

[0025] refer to Figure 2 、 Figure 3 The top surface of the reinforcement tube 2 is fixedly installed with an internal threaded column 10, the internal thread of the internal threaded column 10 is connected to a screw 11, the top of the screw 11 is fixedly installed with a hexagonal end 15, and the bottom surface of the screw 11 is fixedly installed with a circular pushing block 12; the hexagonal end 15 is convenient for personnel to use a socket or a wrench to connect it, and then rotate the screw 11 so that the circular pushing block 12 can move downward, making it convenient for the reinforcement head 9 to be inserted into the cracked side wall of the bridge.

[0026] The implementation principle of an embodiment of a road bridge crack reinforcement device of the present application is as follows: before reinforcing a road bridge crack, the operator first needs to perform necessary repairs on the crack to ensure that the crack sides are flat. Next, the operator will pass the reinforcement tube 2 through the bottom of the installation base plate 1. This can easily attract the circular ring 3 and the annular magnetic sheet 4, thereby achieving the initial installation and fixation of the reinforcement tube 2. At this time, the operator will install the installation base plate 1 and fix it above the crack with bolts, and allow the reinforcement tube 2 to enter the inside of the crack. Then, the operator can use a sleeve or a handle to connect with the hexagonal end 15, and then start to rotate the screw 11. As the screw 11 rotates, the circular pushing block 12 will move downward. Due to its arc-shaped bottom structure, when it contacts the top of the pushing connecting rod 8, it will push the pushing connecting rod 8 and the reinforcement head 9 to move forward. In this way, the reinforcement head 9 can be smoothly inserted into the side wall of the crack, thereby enhancing the connection strength between the reinforcement tube 2 and the crack.

[0027] Then, the personnel connect the external grouting pipe with the grouting connection hole 14, and allow the slurry with a certain pressure from the outside to enter the interior of the reinforcement tube 2. The slurry will be evenly discharged through multiple grouting holes 5 to ensure that the inside of the crack can be evenly filled with slurry. This device not only improves the connection strength between the reinforcement tube 2 and the crack, but also makes the slurry filling more uniform and efficient. The overall structure is compact and low-cost, which greatly improves the convenience and efficiency of operation.
