Efficient sound insulation wall

Abstract

The invention discloses an efficient sound insulation wall. The wall comprises a sound insulation wall body, the sound insulation wall body comprises three branch wall body layers, and the three branch wall body layers successively comprise a first branch wall body, a second branch wall body and a third branch wall body from inside to outside; a first sound insulation layer is arranged between thefirst branch wall body and the second branch wall body, a second sound insulation layer is arranged between the second branch wall body and the third branch wall body, and several connecting pieces penetrate through the first sound insulation layer and are respectively and fixedly connected with the first branch wall body and the second branch wall body; several connecting pieces penetrate through a second sound insulation wall and are respectively and fixedly connected with the second sound insulation layer and the third sound insulation layer; The first sound insulation layer and the secondsound insulation layer are provided with several side-by-side hole passages arranged in a horizontal or vertical direction. The invention provides the efficient sound insulation wall. External soundcan be efficiently isolated, double-layer sound insulation is achieved, and the sound insulation effect is good; the sound insulation board is provided with the hole passages to further improve the sound insulation effect.

Description

technical field [0001] The invention belongs to the field of infrastructure construction, in particular to a high-efficiency sound insulation wall. Background technique [0002] With the development of construction technology and the improvement of human living standards, soundproof rooms came into being. In buildings such as factories and office buildings with high machine noise, a soundproof room is often set up as a space for a small number of people who perform precise operations or mental work. By setting up a soundproof room to isolate external noise, the disturbance of external noise can be avoided. [0003] At present, there are various types of soundproof rooms on the market, but the sound insulation effect of the walls of the soundproof rooms on the market is poor, resulting in poor sound insulation effect of the entire soundproof room, which cannot meet people's requirements for high-quality soundproof rooms. Contents of the invention [0004] The technical pro...
