Hollow light composite sound-absorbing screen
Provided is a hollow light composite sound-absorbing screen. The sound-absorbing screen is composed of sawdust powder, crushed straws and magnesium oxide. The sound-absorbing screen is characterized in that 15-30g of sawdust powder, 10-20g of crushed straws and 10-15g of coat ash are added according to ratios; brine is prepared, and modifiers and reinforcement ribs are added; a plurality of up-and-down vertical-strip-shaped sound-absorbing grooves and a plurality of groups of horizontal-stripe-shaped sound-absorbing groove patterns in longitudinal arrangement are formed in an obverse surface of a lightweight plate, and a sound wave up-and-down frequency graph similar to music playing is formed; side lap structures for installation of the sound-absorbing screen are arranged at the end heads of the left end and at the right end of the lightweight plate, and an inverted-V-shaped assembly male buckle and an inverted-V-shaped assembly female buckle are arranged at the upper end and the lower end of the lightweight plate respectively; sound-absorbing material filling holes are arranged at the left side and the right side of the lightweight plate. The hollow light composite sound-absorbing screen is advantageous in that the lightweight plate is employed as a main wall body of the sound-absorbing screen, and sound waves are absorbed through the sound-absorbing structure and sound-absorbing materials on the surface of the lightweight plate; the hollow light composite sound-absorbing screens can be installed at high speed railways, highways, city entertainment squares with severe noise pollution in a large scale and carry out absorption and isolation of generated noise, and effective noise pollution absorption is achieved.
