Description

Technical Field

[0001] The utility model relates to wall surface technology, in particular to a wall surface anti-cracking structure. Background Art

[0002] At present, houses are important places for people to live and work. With the development of society, people's requirements for the quality of houses are constantly improving. However, some old houses or newly built houses in our country have some quality problems. Among them, the most important one for consumers is wall cracks, because the existence of cracks reduces the integrity, earthquake resistance and service life of the wall, causing adverse effects on the occupants; disputes caused by wall cracks and wall leakage are increasing day by day, and wall cracks have become a house quality problem that needs to be solved. The causes of the cracks are mainly temperature changes and foundation problems. The foundation problems can be improved in design and construction, and the temperature changes are due to the fact that all materials have the property of thermal expansion and contraction. The thermal expansion and contraction coefficients of the multi-layer wall materials are different. Under the same temperature difference, they shrink differently and produce structural cracks. In particular, the temperature difference between winter and summer is large in most parts of our country. After summer or winter, the wall cracks of most houses are obviously revealed.

[0003] Later, a kind of building coating appeared on the market. By applying it on the wall, it makes the wall have certain load-bearing, crack-proof, thermal insulation and other functions, thereby achieving the purpose of protecting the wall and decoration. However, the existing wall structure design is poor, and the joints between the wall inside and outside the wall are not reinforced, which makes the wall prone to cracks, etc., which seriously affects the construction quality, destroys the overall effect of the building, and also leaves certain safety hazards, affecting the service life of the project and the aesthetics, and has a small scope of application.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
