Sound barrier classification which are suitable for what to install and use it
Fourth, the composite sound barrier
The composite sound barrier has the advantages of both transparent and opaque noise barriers. It is half of the resistive barrier barrier, the other half is a transparent sound barrier, from one and two composite from the above four kinds of sound barrier height can be freely combined according to design requirements, can also be customized according to customer requirements road screen.
Third, the microplate transparent barrier barrier
Microporous plate transparent barrier barrier has two layers, which uses the principle of micro-hole sound absorption, in a layer of polycarbonate board wear many holes of 0.8mm diameter, perforation rate of 1%. Another layer of polycarbonate plate is not perforated, the spacing between the two plates is 100mm. It is equivalent to a single layer of microporous sound absorption structure, to solve the contradiction between sound absorption and transparency. Due to the role of sound waves, the pores will not be blocked by dust.
Second, the ordinary transparent sound barrier
Ordinary transparent sound barrier with transparent polycarbonate board (also known as PC board), because it is transparent, sound insulation barrier landscape is better, easier to dissolve into the surrounding environment. Color optional.
First, the resistance barrier barrier
Resistive insulation barrier from the front plate, rear plate, side panels constitute a closed box structure, forming a modular unit. The front plate is a galvanized steel sheet with a perforation rate of 25%, and the back plate and the side plate are non-perforated galvanized steel sheets (colored plates may also be used from the aesthetic point of view). Between the two boards filled with moisture-proof centrifugal glass wool board, sound-absorbing material covered with polyvinyl fluoride film. Column for the 12 # I-beam, column spacing 2m. The column is inserted into the base of reinforced concrete. The standard board inserted between the I-beam, with fasteners to be fixed, installation, maintenance, replacement is extremely simple.
