Technical Field

The utility model relates to the technical field of ventilation and noise reduction, in particular to a detachable sound insulation ventilation wall body.

Background

In the field of noise control engineering, it is often necessary to use sound insulation walls to reduce the effects of noise. From the aspect of noise reduction technology, the sound insulation wall body comprises a heavy wall body and a light wall body. Heavy-duty sound-insulating walls generally have an areal density of greater than 200kg/m ² The wall body comprises various building block wall bodies, concrete wall bodies and the like which are common in the building market; light sound insulation wall is generally characterized by having an areal density of less than 200kg/m ² The wall body comprises a composite wall body which is formed by using common color steel plates, gypsum boards, aluminum plates, thin steel plates and the like in the building market as wall plates. Compared with a heavy sound insulation wall, the light sound insulation wall has the advantages of light weight, convenience in installation and transportation, good surface decoration performance, short construction period, moderate sound insulation and noise reduction performance and the like, is widely used in sound insulation and noise reduction places, and is in absolute predominance in the field of noise control engineering.

Although the lightweight sound insulation wall has a plurality of advantages, the lightweight sound insulation wall has certain limitations in engineering practical application. The sound insulation of the light partition wall is generally lower than that of the heavy wall, if the sound insulation needs to be improved, two or more layers of composite materials are needed, and an air layer with a certain thickness is needed to be arranged between the multi-layer wallboards. The light wall body has low reusability, such as a gypsum board wall body, an aluminum board wall body, a color steel plate and the like, after being disassembled and assembled, the decorative property or the integrity of the board surface is damaged due to fixing parts such as screws and the like, and the light wall body cannot be reused generally, so that the light wall body is not suitable for the project which needs to be overhauled and assembled or can be utilized after being assembled. In addition, for sound insulation and noise reduction engineering, a ventilation opening is usually required to be arranged on a sound insulation wall body, noise leakage is caused by the existence of the ventilation opening, and the noise reduction effect of the sound insulation wall body is greatly reduced, so that in the engineering, the ventilation opening is often replaced by special silencing devices, such as a silencing louver, a resistive silencer, a silencing elbow and the like, the silencing quantity of the silencing devices is between 8 and 30dB, the unit price is 2000-4000 yuan/square meter, the sound insulation quantity of the wall body is generally more than 40dB, the unit price is 400-700 yuan/square meter, the integral sound insulation quantity of the wall body is obviously reduced, the engineering investment is increased, the thickness of the silencer is larger than the thickness of the wall body, and most of the thickness is even more than 3-5 times the thickness of the wall body, so that the integral decoration effect of the wall body is greatly discounted, and the application limitation on engineering application is larger.
