Description

Technical Field

[0001] The utility model relates to the technical field of concrete crack grouting repair and reinforcement structures, in particular to a concrete crack grouting repair and reinforcement structure. Background Technique

[0002] In construction projects, concrete is one of the most common building materials. Due to its advantages such as high strength, good durability, and relatively low cost, it is widely used in various building structures. However, during long-term use, concrete is prone to cracks due to reasons such as material shrinkage, temperature changes, and external forces. Concrete cracks not only affect the appearance of the building structure but also weaken its load-bearing capacity, leading to potential structural safety hazards. Once cracks occur, if not repaired in time, corrosive media such as moisture and salts may penetrate into the interior of the concrete through the cracks, thereby triggering more serious problems such as steel bar corrosion, ultimately affecting the service life of the entire building. Traditional methods have deficiencies in actual operation, mainly reflected in poor reinforcement and waterproof effects of cracks. Traditional methods often rely only on a single repair material for grouting, lacking an internal support structure, resulting in the cracks being prone to re-expansion or the generation of new cracks under the influence of external forces or temperature changes. In addition, the waterproof layer design is imperfect, resulting in the repaired structure being still prone to water penetration in a humid environment, greatly reducing the repair effect. Due to these defects, traditional repair methods are difficult to maintain the stability and integrity of the structure for a long time, with poor practicability and need to be improved. Content of the Utility Model

[0003] The purpose of the utility model is to solve the technical problems put forward in the above background technique.

[0004] The utility model adopts the following technical scheme: a concrete crack grouting repair and reinforcement structure, including a concrete body and a feed inlet. An adhesion layer is arranged inside the concrete body. A support frame is fixedly installed inside the concrete body. Support rods are fixedly installed on the surface of the support frame. A buffer frame is fixedly installed inside the concrete body. Buffer rods are installed on the surface of the buffer frame. An isolation layer is arranged on the surface of the concrete body. A waterproof layer is arranged on the upper surface of the isolation layer.

[0005] Preferably, the support frame and the buffer frame are fixedly connected to the concrete body. Here, the fixed connection between the support frame and the concrete body forms an internal support system, enhancing the load-bearing capacity of the concrete structure, making the repaired structure more stable, and improving the compressive and seismic performance.

[0006] Preferably, the support frame and the buffer frame are fixedly connected, and the buffer frame is arranged at the top of the support frame. Here, the fixed connection design between the support frame and the buffer frame enables the buffer frame to provide additional shock absorption and buffering effects on the basis of the support frame, reducing the impact on the structure when an external force acts, and further improving the stability and durability of the structure.

[0007] Preferably, the waterproof layer is connected to the concrete body. Here, by setting the waterproof layer on the concrete surface and making it closely connected to the concrete body, the waterproof performance of the concrete structure is enhanced, effectively preventing the intrusion of external moisture and avoiding internal damage caused by water penetration.

[0008] Preferably, a collection box is slidably connected inside the feed inlet. A filter plate is fixedly installed inside the collection box, and a pull head is fixedly installed on the surface of the collection box. Here, by slidably connecting the collection box inside the feed inlet, the conveying path of the repair material can be conveniently adjusted to ensure that the grouting material smoothly enters the crack, avoiding material waste and simplifying the repair operation.

[0009] Preferably, the collection box is arranged at the top of the concrete body. Here, the design of the collection box being located at the top of the concrete body enables the repair material to be evenly distributed from the top, ensuring that the grouting material covers the entire crack area and further improving the repair effect.

[0010] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0011] 1. In the present utility model, by setting structures such as an adhesion layer, a support frame, and a buffer frame, a multiple reinforcement system is formed, significantly improving the stability and durability of concrete crack repair. The linkage design of the support frame and the buffer frame enhances the load-bearing capacity and impact resistance of the structure, and the setting of the isolation layer and the waterproof layer further improves the waterproof performance, avoiding secondary damage caused by water penetration after repair.

[0012] 2. In the present utility model, through the design of the collection box and the filter plate inside the feed inlet, the conveying and distribution of the repair material are optimized, ensuring that the material evenly enters the crack and reducing waste, and some agglomerated materials can be screened out, enabling the material to smoothly pour into the gap between the buffer frame and the support frame, thereby improving the smoothness of material pouring.

[0020] Embodiment 1

[0021] Please refer to Figures 1-3, the present utility model provides a technical solution: a concrete crack grouting repair and reinforcement structure, including a concrete body 1 and a feed inlet 2. An adhesion layer 3 is arranged inside the concrete body 1. A support frame 4 is fixedly installed inside the concrete body 1. A support rod 5 is fixedly installed on the surface of the support frame 4. A buffer frame 6 is fixedly installed inside the concrete body 1. A buffer rod 7 is installed on the surface of the buffer frame 6. An isolation layer 8 is arranged on the surface of the concrete body 1. A waterproof layer 9 is arranged on the upper surface of the isolation layer 8. By arranging the adhesion layer 3 inside the concrete, the bonding strength between the grouting material and the crack can be effectively improved, ensuring that the material after crack repair is closely bonded to the original concrete, enhancing the reliability and durability of the repair, preventing subsequent cracks from expanding again. The support frame 4 and the buffer frame 6 are fixedly connected to the concrete body 1. The fixed connection between the support frame 4 and the concrete body forms an internal support system, improving the load-bearing capacity of the concrete structure, making the repaired structure more stable, and enhancing the compressive and seismic resistance. The support frame 4 and the buffer frame 6 are fixedly connected. The buffer frame 6 is arranged at the top of the support frame 4. The fixed connection design between the support frame 4 and the buffer frame 6 enables the buffer frame 6 to provide additional shock absorption and buffering effects on the basis of the support frame 4, reducing the impact on the structure when an external force acts, and further improving the stability and durability of the structure. The waterproof layer 9 is connected to the concrete body 1. By arranging the waterproof layer 9 on the concrete surface and making it closely connected to the concrete body, the waterproof performance of the concrete structure is enhanced, effectively preventing the intrusion of external moisture and avoiding internal damage caused by water penetration.

[0022] Embodiment Two

[0023] Please refer to Figures 1-3 , a collection box 10 is slidably connected inside the feed inlet 2. A filter plate 11 is fixedly installed inside the collection box 10. A pull head 12 is fixedly installed on the surface of the collection box 10. By slidably connecting the collection box 10 inside the feed inlet 2, the conveying path of the repair material can be conveniently adjusted, ensuring that the grouting material smoothly enters the crack, avoiding material waste, and simplifying the repair operation. The collection box 10 is arranged at the top of the concrete body 1. The design that the collection box 10 is located at the top of the concrete body enables the repair material to be evenly distributed from the top, ensuring that the grouting material covers the entire crack area and further improving the repair effect.

[0024] Working principle: The concrete crack grouting repair and reinforcement structure forms a stable internal support system through structures such as the internal support frame 4, buffer frame 6, and adhesion layer 3. During the repair process, first, the surface of the crack is cleaned to ensure good contact between the repair material and the concrete. Then, the repair material is injected through the feed port 2. The material passes through the slidably connected collection box 10 and filter plate 11 and is evenly distributed into the crack. The adhesion layer 3 ensures firm adhesion of the material to the crack surface. The support frame 4 and the buffer frame 6 work together to provide stable support for the repaired structure, preventing the crack from expanding again due to external forces or temperature changes. At the same time, the external isolation layer 8 and waterproof layer 9 further enhance the waterproof performance of the structure, preventing moisture from invading the repair area. After the entire repair is completed, it is ensured through inspection that the material is evenly distributed, the support is stable, and the waterproof effect meets the standards, ultimately achieving comprehensive reinforcement and long-term protection of the concrete structure.
