The basic structure of the vinyl sound barrier

The vinyl sound barrier usually adopts brick or concrete structure, and the indoor noise barrier refers to the structure of steel plate, wood plank, PMMA/POLYCARBONATE SHEET plastic wrench, gypsum board and foam aluminum. The vinyl sound barrier is mainly composed of steel structure column and sound absorption and isolation screen plate. The column is the main stress component of the sound barrier, which is fixed on the embedded steel plate beside the road anti-collision wall or track by bolts or welding; Sound absorption and insulation board is the main sound insulation and absorption component. It is fixed in the H-shaped column groove through high-strength safety clips to form a sound barrier. The design of sound barrier has fully considered the wind load of elevated expressway, urban light rail and subway, the impact safety of traffic vehicles and all-weather outdoor anti-corrosion. It has the advantages of beautiful appearance, exquisite manufacture, convenient transportation and installation, low cost and long service life. It is especially suitable for the anti noise use of elevated expressway, urban light rail and subway. It is the most ideal sound insulation and noise reduction facility in modern cities.

The height of the vinyl sound barrier is between 1m and 5m, and the average noise reduction in the effective area is up to 10 ~ 15dB (125Hz ~ 4000Hz, 1 / 3 octave), up to 20dB. Generally speaking, the higher the vinyl sound barrier or the farther away from the sound barrier, the better the noise reduction effect.
