Embodiment Construction

[0011] As shown in the accompanying drawings, the sound-absorbing panel of the present invention consists of a surface grid 1 , sound-absorbing cotton 2 and an outer frame 3 . The shape of the outer frame 3 is pot-shaped, which is composed of the surrounding outer walls and the bottom surface. It is produced by the method of pultrusion with glass fiber composite material. It has the characteristics of high strength, corrosion resistance, durability, light weight and low cost. It is suitable for mass production, and the external dimensions can be designed into various specifications. It can be directly pasted on the concrete sound insulation wall with resin or used alone as a sound barrier.

[0012] The outer frame 3 is built with sound-absorbing cotton 2, and the surface of the sound-absorbing cotton 2 is distributed with a tapered structure, so that the principle of the sound-absorbing wedge can be used to make the average oblique incidence sound absorption rate reach 96%, fur...

Abstract

A sound absorption board of glass fiber composite material is prepared as setting external frame to be basin form, placing sound absorption felt in said frame with base surface and peripheral wall, arranging surface grille above said felt, firm-jointing edge of said grill with edge of said frame, forming both said grille and said frame by glass fiber composite material, distributing conical structure at surface of said felt, sticking said felt on internal surface of said frame by epoxy and preparing said frame by extruding process.

Description

technical field [0001] The invention relates to an environmental protection facility, in particular to an environmental protection facility for eliminating or alleviating noise. Background technique [0002] Nowadays, more and more urban residents are moving to new houses. While people are concerned about the convenience of life and whether the air quality is good, the level of noise from railways, highways and urban noise in the residential area has become an important factor when buying a house. And if people are not careful, they will stray into the noise pollution area. An environmental monitoring report shows that nearly two-thirds of urban residents across the country live and work in an environment with excessive noise. Noise pollution, which interferes with people's normal work and life, and even affects social stability, is one of the environmental issues that urban residents are most concerned about and reflect most strongly. People all have this experience, whe...
