Description

Technical Field

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

[0002] Road and bridge crack reinforcement refers to the use of certain technical means and methods to repair and reinforce cracks that appear in the bridge during use, so as to ensure the safety, durability and service life of the bridge structure. The generation of cracks may be caused by various factors such as bridge design defects, construction quality problems, long-term load, environmental factors (such as temperature, humidity changes, freeze-thaw effects, etc.) and natural disasters. The purpose of crack reinforcement is to eliminate or reduce the damage of cracks to the structure, restore the bearing capacity of the bridge, and prevent the cracks from further expanding or causing other structural problems. The current reinforcement method is generally to pour cement, asphalt or other substances, but the current pouring is generally done by connecting high-pressure pipes, which requires manual support, is time-consuming and labor-intensive, and there are no other reinforcement structural devices after pouring. For this reason, we have proposed a new road and bridge crack reinforcement structure. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, the utility model provides a technical solution: a road bridge crack reinforcement structure, comprising a wall 1, a fixing plate 101 is tightly attached to the side wall of the wall 1, the center of the fixing plate 101 is set at the crack, and connecting plates 104 are welded to the two walls of the wall 1 respectively, and the connecting plates 104 are fixed by fixing nails 108;

[0024] A connecting groove 2 and a grouting hole 202 are provided on the upper wall of the fixed plate 101. The grouting hole 202 is on the lower side of the connecting groove 2. A grouting pipe 203 is inserted into the inside of the grouting hole 202. The outer wall of the grouting pipe 203 is fixedly sleeved with a fixed screw sleeve 204 and a connecting ring 205. The connecting ring 205 is on the upper side of the fixed screw sleeve 204. The outer diameter of the fixed screw sleeve 204 is adapted to the inner diameter of the connecting groove 2. Handles 206 are fixedly welded on both walls of the connecting ring 205.

[0025] According to the overall structure of the device, no human support is required when filling the cracks, which saves time and effort. At the same time, a fixing device is provided to reinforce the cracked bridge and increase the stability of the bridge. At the same time, the filling device can be matched with the fixing device, which is beneficial to improving the pouring efficiency of the staff.

[0026] like Figure 3 As shown, two sets of fixing blocks 102 are fixedly welded to both walls of the fixing plate 101 , and first bolts 103 are provided inside the fixing blocks 102 .

[0027] The fixing blocks 102 are welded to the four corners of the fixing plate 101 , and the fixing plate 101 can be fixed by the first bolts 103 , so that the fixing plate 101 is fixed at the crack.

[0028] like Figure 5As shown, a slot 105 is provided on the upper wall of the connecting plate 104 , and a U-shaped plate 106 is fixed on the upper end of the slot 105 . The notch on the lower wall of the U-shaped plate 106 is adapted to the width of the connecting plate 104 .

[0029] By using the U-shaped plate 106 to squeeze and fix the connecting plate 104, the connecting plate 104 can be tightly attached to the bridge wall, making the device less likely to fall off.

[0030] like Figure 5 As shown, two groups of thread grooves are provided on the upper wall of the U-shaped plate 106 , and second bolts 107 are provided in the thread grooves provided on the upper wall of the two groups of U-shaped plates 106 .

[0031] Fixing the U-shaped plate 106 by the second bolts 107 can increase the stability of the connection plate 104 fixed to the bridge wall.

[0032] like Figure 3 As shown, a closing gasket 201 is provided inside the connecting groove 2 . The closing gasket 201 is provided in an annular groove provided on the inner wall of the fixing plate 101 . The material of the closing gasket 201 is rubber.

[0033] By arranging the sealing gasket 201 in the annular groove, the fixing screw sleeve 204 can be fully squeezed against the inner wall of the fixing plate 101 when connected to the connecting groove 2, thereby achieving a sealing effect and preventing the liquid from flowing out during the injection.

[0034] like Figure 2 As shown, the fixing plate 101 and the connecting plate 104 are made of Q345 steel and are coated on the surface.

[0035] By using Q345 steel and providing a coating on the surface, the stability of the bridge reinforcement can be increased and equipment corrosion can be prevented.

[0036] like Figure 4 As shown, the upper end of the grouting pipe 203 is threaded, and the outer wall of the handle 206 has anti-slip grooves.

[0037] The upper end of the grouting pipe 203 is set to be threaded and the outer wall of the handle 206 has anti-slip grooves, which facilitates the connection of the grouting equipment and makes it easy for the staff to hold the handle 206 to rotate and connect the fixing screw sleeve 204 to the connecting groove 2.

[0038] Working principle: This structure can reinforce the bridge wall with cracks, which can increase the safety and stability of the bridge. When actually reinforcing and repairing the cracks in the bridge, grouting or pouring other substances is generally used, but the connecting pipe is also required to pour the cracks. First, different lengths of reinforcement devices are selected according to the length of the bridge. The connecting plate 104 and the fixing plate 101 can be processed into different sizes and lengths through the mold according to the actual length of the bridge and the crack. The center of the fixing plate 101 is aligned with the crack, and then the U-shaped plate 106 is squeezed into the slot 105. At the same time, the first bolt 103, the second bolt 107 and the fixing nail 10 8 Fix the fixing plate 101 and the connecting plate 104 on both sides of the crack to increase the stability of both sides of the crack and prevent the reinforcement equipment from falling off easily; when pouring, fill the other parts of the crack first according to the length, then hold the handle 206 and rotate the fixing screw sleeve 204 to insert the grouting pipe 203 into the grouting hole 202, and then connect the pouring equipment to the grouting pipe 203 head to pour the reinforcement material. After the pouring is completed, just rotate and disassemble the grouting pipe 203. The fixing plate 101 and the connecting plate 104 can reinforce both sides of the bridge crack for a long time. Because they are made of high-quality steel and have a coating, they can increase the stability of the road bridge.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
