Classification of sound insulation barriers
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.
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.
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.
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.
According to the material points, there are: all-metal sound barrier, all glass steel insulation barrier, durability board (PC) full transparent barrier, high-strength cement insulation barrier, cement sawdust insulation barrier;
According to the contours of the points, there are: upright sound barrier, upright small arc sound barrier, fully enclosed sound barrier;
According to the combination of points, there are: all transparent sound barrier, all opaque sound barrier, smoke insulation board and transparent material combination of sound insulation barrier;
According to the panel form points, there are: wave board, louver, flat perforated insulation barrier.
Four types of barrier barriers are, resistive sound barrier, ordinary transparent sound barrier, microplate transparent sound barrier and composite sound barrier.
