Introduction of sound insulation system for light steel structure buildings in Chongqing

Introduction to the sound insulation system of light steel structure houses in Chongqing As a new type of building model, light steel structure houses, many people do not understand its performance. Everyone extrapolates from past experience. You can feel the sound insulation effect of the light steel house. Insulation will be poor, which is a characteristic of metallic materials. but it is not the truth. The sound insulation effect of the light steel house is very good. The walls and floors of the light steel house system are composed of independent bridges with two pipe fittings. The square tube is only intermittently connected with v-joints smaller than 2 mm. The heat transfer channel is weak and almost cut off. The bridge makes the inside and outside of the building two independent thermal circulation systems. The characteristics of light steel structure building sound insulation system The square tube (rectangular tube) of the hollow mechanism interferes and weakens the transmission of sound. Rock wool is filled in the bridge space and has good vibration isolation and sound absorption functions, which can prevent the intrusion of external noise and cluttered vibrations. In order to meet the overall requirements of sound insulation and sound insulation, glass wool can be filled between the inner and outer walls of the light steel structure house and the floor joists to effectively block the air part. It is spread through the air. The test results show that the glass wool filler can further enhance the air transmission and sound insulation effect of the light steel structure, reaching more than 50dB. The light steel structure house can meet the service life requirements before the surrounding structure is treated
