Description

Technical Field

[0001] This utility model relates to the field of bridge crack reinforcement structure technology, and more specifically, to a road bridge crack reinforcement structure. Background Technology

[0002] Current reinforcement techniques for road and bridge cracks mainly involve filling the cracks with materials such as cast concrete, epoxy resin, or polyurethane. Some crack reinforcement schemes combine this with reinforcing steel bars and carbon fiber cloth. These methods can improve the load-bearing capacity and durability of cracks to some extent, but the reinforcement effect is prone to failure under long-term high-frequency vibration, vehicle loads, and environmental erosion. In particular, insufficient internal support within the cracks can lead to easy re-expansion or damage.

[0003] In existing technologies, simple castable materials are difficult to form effective internal support during crack repair. Because castable materials rely primarily on fluidity to fill cracks, after curing they typically only fill the surface or a portion of the crack's depth, leaving the deeper layers with weak support. This results in a lack of stable internal structural support. Under long-term loads from vehicles and environmental vibrations, stress concentration occurs in the cracked areas, causing the castable material to gradually detach, crack, or fail at the stress points. Furthermore, when crack width varies significantly or the shape is irregular, the filling effect of the castable material becomes even more uneven, further reducing its internal support capacity and ultimately affecting the crack reinforcement effect and the durability of the bridge structure.

[0004] Therefore, a road and bridge crack reinforcement structure is proposed to address the above problems. Utility Model Content

[0026] Example:

[0027] Please see Figure 1-3 A road and bridge crack reinforcement structure includes a reinforcement platform 1, an assembly box 2 fixedly connected to the top of the reinforcement platform 1, a handle 11 fixedly connected to one end of the assembly box 2, an installation block 21 movably connected to the assembly box 2, a movable component installed inside the assembly box 2, and a placement frame 38 installed inside the assembly box 2, with multiple evenly distributed reinforcement frames 4 on the placement frame 38.

[0028] This solution addresses many shortcomings of traditional crack reinforcement methods by designing a road and bridge crack reinforcement structure. The hollow design and porous structure on the outer surface of the reinforcement frame 4 not only reduce the weight of the frame and facilitate construction, but also provide a uniform flow channel for the injection material, enhancing the adhesion between the material and the crack wall and the overall anchoring effect. The combination of the support seat 41 and the reinforcement strip 42 allows the frame to adapt to the shape and size of the crack after unfolding inside the crack, forming a support structure similar to an "umbrella" or "frame," thereby significantly improving the tensile and shear strength and overall stability of the crack. In addition, the cooperation between the moving component and the electric shearing machine 37 greatly improves construction efficiency and accuracy, allowing the frame length and insertion depth to be flexibly adjusted according to the actual needs of the crack, further meeting the needs of complex crack repair, significantly improving the repair quality and durability of the crack, and extending the service life of the bridge structure.

[0029] The moving component includes a servo motor 31 installed on the inner wall of the assembly box 2. A reciprocating lead screw 32 is fixedly connected to the output end of the servo motor 31. One end of the reciprocating lead screw 32 is rotatably connected to the inner wall of the assembly box 2. A screw sleeve 33 is installed around the reciprocating lead screw 32. A limit block is fixedly connected to one end of the screw sleeve 33. The limit block is slidably connected to a limit groove opened in the inner wall of the assembly box 2.

[0030] One end of the screw sleeve 33 is fixedly connected to an electric actuator 34, the output end of the electric actuator 34 is fixedly connected to a moving block 35, the bottom end of the moving block 35 is fixedly connected to a magnetic rod 36, and an elastic extrusion strip is installed at the bottom end of the moving block 35 and at the outer perimeter of the magnetic rod 36.

[0031] The moving component, through the cooperation of servo motor 31, reciprocating lead screw 32, threaded sleeve 33, and electric push rod 34, achieves precise removal, movement, and insertion of the reinforced frame 4. Specifically, servo motor 31 is fixedly installed on the inner wall of assembly box 2, and its output end is fixedly connected to reciprocating lead screw 32. By rotating forward or backward, servo motor 31 drives reciprocating lead screw 32 to rotate, thereby driving threaded sleeve 33 to move along the axial direction of lead screw. Limit block is fixedly connected to the outside of threaded sleeve 33, and limit block is slidably connected to limit groove on inner wall of assembly box 2 to ensure stable and accurate linear motion trajectory of threaded sleeve 33. One end of threaded sleeve 33 is connected to electric push rod 34, and the output end of electric push rod 34 is fixedly connected to moving block 35. Magnetic rod 36 is installed at the bottom of moving block 35, and elastic compression strip is installed around the outer perimeter of magnetic rod 36 to further fix the frame and prevent shaking or detachment during movement.

[0032] In practical applications, this moving component can efficiently complete the removal and insertion of the reinforced frame. The construction worker starts the servo motor 31, which drives the reciprocating screw 32 to rotate, and the threaded sleeve 33 moves along the screw to directly above the target reinforced frame 4. Then, the electric actuator 34 is activated, extending and driving the moving block 35 downwards, allowing the magnetic rod 36 to extend into the hollow structure of the target frame 4. The magnetic rod 36 attracts the reinforcing strips 42 of the frame, removing the frame from the placement rack 38. Simultaneously, the elastic compression strip provides auxiliary fixing force to ensure frame stability. The servo motor 31 restarts, driving the reciprocating screw 32 in the reverse direction, transporting the attracted frame to the mounting slot at the bottom of the assembly box 2. At this point, the electric actuator 34 restarts again, driving the moving block 35 to extend downwards, inserting the reinforced frame 4 into the bridge crack.

[0033] An installation slot is provided at the bottom of the assembly box 2, and an electric shearing machine 37 is installed at the bottom of the assembly box 2 and on one side of the installation slot.

[0034] The assembly box 2 has an installation slot at its bottom, which is used for inserting and installing the reinforcement frame 4 to ensure that the frame can pass smoothly through the assembly box 2 and enter the crack in the bridge. In order to adapt to the reinforcement requirements of different crack depths, an electric shearing machine 37 is installed at the bottom of the assembly box 2 and on one side of the installation slot to cut the reinforcement frame 4, so as to ensure that the length of the frame can be adjusted according to the specific depth of the crack.

[0035] In practical applications, when the reinforcing frame 4 is moved to the mounting slot at the bottom of the assembly box 2 by the operation of the moving component, if the crack depth is shallow, the frame part exceeding the required length can be quickly cut by the electric shearing machine 37. According to the depth requirements of the crack on site, the construction personnel start the electric shearing machine 37 and drive the shearing blade to precisely cut the frame so that its length matches the crack depth. After the cutting is completed, the frame can be inserted into the crack through the mounting slot while maintaining a suitable length.

[0036] The reinforcing frame 4 has a hollow design and a porous outer surface. Multiple evenly distributed support seats 41 are rotatably connected to the outer perimeter of the reinforcing frame 4, and a reinforcing strip 42 is rotatably connected to one end of each support seat 41.

[0037] The reinforcing frame 4 features a hollow design with a porous outer surface. This design makes the frame lightweight and easy to install. The hollow structure provides a channel for the injection material, such as concrete, epoxy resin, or polyurethane, ensuring that the injection material can evenly fill the interior of the frame and around the crack, thus forming a strong overall reinforcement structure with the frame. In addition, the porous design of the outer surface of the reinforcing frame 4 significantly increases the contact area between the injection material and the frame, improving the adhesion and anchoring effect. It also allows the material to penetrate into the crack wall, further enhancing the strength and durability of the crack.

[0038] The reinforcing frame 4 is surrounded by multiple evenly distributed support seats 41. Each support seat 41 has a reinforcing strip 42 rotatably connected to one end. The support seats 41 provide support and guidance during the coiling and unfolding of the frame. The rotatable connection design allows the frame to flexibly adapt to the shape and size of the crack after it is inserted into the crack. The reinforcing strips 42 are evenly distributed on the outer surface of the reinforcing frame 4. In the initial state, they adhere to the surface of the frame and remain taut. When the frame is inserted into the crack and the fixation is released, the reinforcing strips 42 naturally unfold under the action of gravity and elasticity, adhering to the crack wall and forming a support structure similar to an "umbrella" or "frame".

[0039] In practical applications, the reinforcing frame 4 is inserted into the bridge crack via a movable component. After the fixation is released, the support base 41 and the reinforcing strip 42 work together to ensure a tight fit between the frame and the crack wall. The porous structure on the outside of the frame ensures that the grouting material penetrates evenly into the crack wall and around the frame. At the same time, the unfolded reinforcing strip 42 provides additional support to prevent the crack from expanding under subsequent vibration or load. This design not only improves the tensile strength, shear strength, and stability of the crack but also extends the service life of the crack repair.

[0040] Working principle:

[0041] After the assembly box 2 is moved to the location of the bridge crack by the reinforcement plate 1, the moving components inside the assembly box 2 are used to achieve precise removal, movement, and insertion of the reinforcement frame 4. Specifically, the servo motor 31 drives the reciprocating screw 32 to rotate, and the screw sleeve 33 moves along the axial direction of the screw to directly above the target reinforcement frame 4. Then, the electric push rod 34 drives the moving block 35 to move downward, so that the magnetic rod 36 extends into the hollow structure of the reinforcement frame 4. The frame is removed from the placement rack 38 by the attraction of the reinforcement strip 42 by the magnetic rod 36. At the same time, the elastic compression strip provides auxiliary fixing force to ensure that the frame is stable and does not shake or detach during the movement.

[0042] After the skeleton is delivered to the mounting slot at the bottom of the assembly box 2 via the moving component, if the crack depth is shallow, the electric shearing machine 37 can cut the skeleton to match its length with the crack depth. After cutting, the electric push rod 34 is activated again to insert the skeleton into the crack. After insertion, the unfixed skeleton unfolds due to gravity and elasticity, and the support 41 and the reinforcing strip 42 work together to make the skeleton fit tightly against the crack wall.

[0043] The reinforcing skeleton 4 inserted into the crack provides a uniform flow channel for the injection material through its hollow design and porous outer surface, while enhancing the adhesion between the injection material and the crack wall and the overall anchoring effect. The support seat 41 and the unfolded reinforcing strip 42 form a support structure similar to an "umbrella" or "frame," which improves the tensile strength, shear strength, and stability of the crack. Finally, the cast material and the skeleton form an integral composite structure, significantly improving the crack repair quality and durability, and meeting the reinforcement needs of complex cracks.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
