Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a wall crack repair and reinforcement structure. Background Art

[0002] Currently in the field of building structures, as time goes by, uneven foundations or external factors may cause the design load of the house to be lower than the actual load, resulting in larger cracks in the wall structure due to excessive load.

[0003] Cracks on the wall surface are generally filled with concrete, but concrete is a brittle material with a high elastic modulus and relatively poor deformation capacity. After filling the cracks in the wall, as water is lost, the volume of the concrete decreases, and the shrinkage stress exceeds the bonding force between the concrete and the wall, new cracks will appear at the filled parts, and the cracks may further weaken the integrity of the wall. Alternatively, the wall can be fixed with bolts and reinforced with rods, but the bolts will destroy the original structure of the wall, and then local stress concentration will occur at the contact point between the bolts and the wall, which may cause new cracks. In coastal areas, the air humidity is high and the water vapor in the air has a high salt content, which seriously corrodes the bolts and easily causes failure of the reinforced structure.

[0004] To this end, the utility model provides a wall crack repair and reinforcement structure to solve the above problems. Utility Model Content

[0024] 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.

[0025] Example 1:

[0026] See also Figure 1-5 A wall crack repair and reinforcement structure includes an outer shell 3 and a second adhesive 5. A second concrete 2 is arranged inside the outer shell 3. A first adhesive 4 is arranged at the port of the outer shell 3. Several circular tubes 6 with different radii are arranged in the crack. The circular tubes 6 are fitted with the inner wall of the crack. The second adhesive 5 is arranged in the crack and outside the circular tubes 6. The first concrete 1 is arranged in the circular tubes 6.

[0027] The shell 3 is arranged on the wall surface, and is bonded to the wall surface by the first adhesive 4 and the second concrete 2, with the top of the shell 3 tilted at 45 degrees.

[0028] The first adhesive 4 is epoxy resin glue.

[0029] The surface of the round tube 6 is provided with rough textures, and the round tube 6 is made of stainless steel.

[0030] The second adhesive 5 is made of polyurethane glue, and the housing 3 is made of ABS plastic.

[0031] The length of the circular tube 6 inside the crack is twice as long as the length outside the crack.

[0032] One end of the circular tube 6 away from the crack is fixedly connected to the second concrete 2 .

[0033] Working principle: After the circular tube 6 is inserted into the crack, the circular tube 6 is in close contact with the crack, so that the stress on one side of the crack is transmitted to the other side through the circular tube 6, thereby ensuring a stable crack shape and making the stress more evenly distributed in the entire wall crack area, reducing local stress concentration points, thereby enhancing integrity and stability.

[0034] The first concrete 1 in the circular tube 6 further improves the bearing capacity and deformation resistance of the circular tube 6. The roughness set on the outer side of the steel tube facilitates fixation with the second adhesive 5, thereby filling the tiny gap between the circular tube 6 and the crack to form a tight connection. The second adhesive 5 has a certain elasticity. When the wall crack is slightly deformed, the second adhesive 5 is elastic and the wall will not crack easily. The second adhesive 5 offsets the shear force of the wall, thereby improving the overall performance of the wall crack after repair, and having waterproofness and durability.

[0035] The circular tube 6 outside the crack is then fixed by the second concrete 2 on the outside and the outer shell 3, so that the circular tube 6 is limited by the second concrete 2 on the outside. The second concrete 2 provides compressive support and lateral constraints to the circular tube 6, thereby improving the bearing capacity of the circular tube 6 at the crack location.

[0036] The waterproof property of the interior of the second concrete 2 is improved by the inclination provided on the outer shell 3 and the first adhesive 4 .
