Description

Technical Field

[0001] The utility model belongs to the technical field of anti-crack stickers, and in particular relates to an anti-crack sticker used on a middle or lower layer to resist reflective cracks. Background Art

[0002] When reinforcing old concrete pavements, an asphalt overlay is often added. When the tensile stress generated by concrete displacement exceeds the tensile strength of the asphalt overlay, the overlay will crack. These cracks are called radial cracks. To prevent the formation of reflective cracks, anti-cracking tape is usually applied to the middle and lower layers to combat these.

[0003] Current anti-cracking stickers are usually made of a layered membrane structure that uses high-molecular polymers to combine high-temperature resistant woven fabrics, polyester fibers and high-strength meshes. On the one hand, this type of anti-cracking sticker is not waterproof, and road surface water can easily penetrate the anti-cracking sticker and enter the roadbed. Long-term action will cause voids in the roadbed and accelerate road cracking. On the other hand, the tensile capacity of a single-layer tensile mesh is limited, and directly superimposing a double-layer tensile mesh will easily cause wear between the two layers of tensile mesh, affecting their strength.

[0004] Therefore, it is necessary to design an anti-crack sticker that improves waterproof performance and tensile strength and is used in the middle and lower layers to resist reflective cracks to solve the current technical problems. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides an anti-crack sticker which improves waterproof performance and tensile strength and is used on the middle and lower layers to resist reflective cracks.

[0006] The technical solution of the present invention is: an anti-crack patch is used in the middle and lower layers to combat reflective cracks, comprising a high-temperature resistant fabric layer, a water-blocking layer, a first tensile mesh layer, a buffer layer and a second tensile mesh layer bonded together from top to bottom; the buffer layer is a rubber-plastic thermal insulation material layer, and the first tensile mesh layer and the second tensile mesh layer are staggered on both sides of the buffer layer.

[0007] The first tensile mesh layer has uniformly arranged first longitudinal threads and first transverse threads, and the second tensile mesh layer has uniformly arranged second longitudinal threads and second transverse threads; the first longitudinal threads are interlaced with the second longitudinal threads, and the first transverse threads are interlaced with the second transverse threads.

[0008] The first longitudinal wire, the first transverse wire, the first longitudinal wire and the second longitudinal wire are all carbon steel wires with a diameter of 0.28 to 0.35 mm.

[0009] The high temperature resistant fabric layer is glass fiber cloth.

[0010] Scales are evenly arranged on the side of the high-temperature resistant fabric layer away from the water-blocking layer.

[0011] The water-blocking layer is a rubber-plastic thermal insulation material layer.

[0012] A water-proof layer is fixedly provided on the side of the second tensile mesh layer facing away from the buffer layer.

[0013] The water-proof layer is a polyurethane film.

[0014] Beneficial effects of the utility model:

[0015] (1) In the present invention, the water-blocking layer can block the water above the anti-cracking patch, preventing it from penetrating downward into the roadbed and affecting the stability of the roadbed. At the same time, the buffer layer is a rubber-plastic thermal insulation material layer, which also has a certain waterproof and anti-seepage effect, and can further improve the waterproof performance of the anti-cracking patch;

[0016] (2) The first tensile mesh layer and the second tensile mesh layer are combined together to multiply the tensile strength of the anti-cracking patch. At the same time, the first tensile mesh layer and the second tensile mesh layer are staggered and evenly stressed, thereby improving the tensile strength.

[0017] (3) A buffer layer is provided between the first tensile mesh layer and the second tensile mesh layer to prevent wear between the first tensile mesh layer and the second tensile mesh layer. BRIEF DESCRIPTION OF THE DRAWINGS

It penetrates downward into the roadbed and affects the stability of the roadbed. At the same time, the buffer layer 4 is a rubber-plastic thermal insulation material layer, which also has a certain waterproof and anti-seepage effect, which can further improve the waterproof performance of the anti-cracking patch; the first tensile mesh layer 3 and the second tensile mesh layer 5 are compounded together to multiply the tensile ability of the anti-cracking patch. At the same time, the first tensile mesh layer 3 and the second tensile mesh layer 5 are staggered and evenly stressed, thereby improving their tensile effect; in addition, a buffer layer 4 is provided between the first tensile mesh layer 3 and the second tensile mesh layer 5 to avoid wear between the first tensile mesh layer 3 and the second tensile mesh layer 5.
