Abstract
The utility model discloses an acoustic panel for a cement noise barrier, which comprises a sound insulation layer, a cavity layer and a sound absorption layer, wherein the sound insulation layer is a theta-shaped frame body; the sound absorption layer is arranged on the surface of the sound insulation layer frame body; the cavity layer is arranged between the sound absorption layer and the sound insulation layer; and circular holes are arranged on the sound absorption layer. A sound absorption groove plate is arranged in the cavity layer and a plurality of parallel U-shaped grooves are arranged on the sound absorption groove plate. Reinforced steel bars are arranged in the sound insulation layer, the longitudinal section of the circular hole is trapezoidal, the circular holes are uniformly distributed at equal intervals, the top of the sound insulation layer frame body is convex, and the bottom of the sound insulation layer frame body is concave. The convex top and the concave bottom of the sound insulation layer frame body are fitted. The acoustic panel adopts the high-strength cement as raw material and has the advantages of good noise reduction, good material weatherability, good structural mechanical property, corrosion resistance, no pollution, light weight, high strength and long service life.
Description
Technical field
The utility model relates to a kind of cement sound barrier acoustic.
Background technology
Sound barrier is meant when noise source and recipient are in certain distance, in order to reduce the infringement of noise to the recipient, the barrier that blocks noise is set between the two, is commonly called as sound barrier.Sound barrier is mainly used in the sound insulation and noise reducing in the traffic urban operating mechanisms such as speedway, overhead composite road, urban light rail, railway, it mainly is made up of steel work column and sound barrier two parts, column adopts H shaped steel, be the main stressed structure of sound barrier, it is by being bolted on crashproof wall of road or the embedded board; Sound barrier is main sound insulation, sound absorbing member, and it is fixed in the H shaped steel groove by high-intensity spring clip; Problems such as the manufacturing cost of such sound barrier is higher, it is anticorrosion in the open to exist, protection against the tide and application life are long.
