The sound insulation wall

The sound insulation wall is divided into a reflection type sound barrier with pure sound insulation, and a composite type sound barrier combining sound absorption and sound insulation. The latter is made by more effective sound insulation. Most sound barriers use a combination of sound absorption and sound insulation products, which are characterized by targeted control of the generation and transmission characteristics of road noise. For example, the soundproof partition wall of cars and roads or the friction sound of locomotives and tracks is on the lower part of the road, and the sound has the characteristic of diffracting through the upper part of the screen.

The use of transparent reflective sound insulation panels in the middle of the sound barrier can effectively interrupt the propagation of sound waves; at the same time, it also provides a wide field of vision for drivers and residents. In the field of architectural acoustics, through acoustic management, reverberation time and indoor acoustic environment are controlled to meet the requirements of professional venues. According to the application environment of sound barriers, sound barriers are divided into traffic noise barriers, equipment noise attenuation noise barriers, and industrial factory noise barriers. According to the material classification, it can be divided into the following categories: metal sound barriers (metal louvers, metal mesh openings), concrete sound barriers (lightweight concrete, high-strength concrete), PC sound barriers, FRP sound barriers, etc. According to different uses, it can be divided into the following categories: railway sound barrier, road sound barrier, urban landscape sound barrier, residential area noise reduction barrier, etc.

Practice of indoor soundproof wall:

Soundproof wall elastic line positioning: According to the construction drawing, the position control line of the movable partition wall is released on the indoor ground, and the position line of the partition wall is led to the side wall and the top plate. The spring line is the installation position line where the fixing piece should be ejected.

Installation of soundproof wall track fixings: Select track fixings according to design requirements. Before installing the track, the closing method of the wall, the ground, and the ceiling must be considered and the installation of the movable partition wall is facilitated. By calculating the weight of the movable partition wall, the load on the track, the specifications of the embedded parts, and the fixing method are determined. The embedded parts of the track should be installed firmly, and the track and the main structure should be firmly fixed, and all metal parts should be rust-proofed.

Prefabricated partition fan for soundproof wall: First, determine the net size of the movable partition according to the design drawings and the actual measured size on site. Then, according to the installation method of the track, the net size of the movable partition and the design division requirements, calculate and determine the size of each partition fan of the movable partition, and finally draw a large sample map for processing. Since the movable partition wall is a movable wall, it is required that each partition fan should be as beautiful and delicate as a decorative door. It should be prefabricated in a professional manufacturer, and the quality of the product can be ensured by processing and trial assembly.
