Description

[0001] The utility model relates to the technical field of engineering construction, in particular to a wall structure for sound insulation and noise reduction. Background Art
[0002] Walls are an important part of buildings. Their functions are to bear weight, enclose or separate spaces. Walls are divided into load-bearing walls and non-load-bearing walls according to the stress conditions and materials of the walls. They are divided into solid walls, sintered hollow brick walls, hollow walls and composite walls according to the wall construction methods. With the rapid development of people's living standards, cinemas, KTVs, bars, recording studios and other places with huge noises have disturbed people's daily lives. These places generally use soundproof walls to block noise and reduce the disturbance of noise to people's lives. At present, people's economic level is developing rapidly, and these places with large noise generation are also increasing day by day, providing entertainment for people. This The demand for sound insulation and noise reduction walls is also increasing. Usually, the main method for sound insulation and noise reduction of walls is to set a keel inside the wall, fill it with sound insulation surface, and set sound insulation boards on both sides of the keel to achieve sound insulation and noise reduction. Although this structure can adapt to most sound insulation environments, when vibration occurs, this structure cannot perform buffering and shock absorption well, which leads to poor effect in reducing the noise generated by vibration. In addition, this structure has a short sound wave propagation path, which cannot effectively reduce the consumption of sound waves, resulting in poor sound insulation effect. For this reason, we propose a wall structure for sound insulation and noise reduction. Utility Model Content
