Abstract
The utility model discloses a composite sound absorption and noise insulation barrier. The composite sound absorption and noise insulation barrier is characterized by comprising a taper-hole noise absorption plate and a hot galvanized steel plate, wherein the taper-hole noise absorption plate is arranged on the front surface; the hot galvanized steel plate is arranged on the back surface; an environment-friendly fiber sound absorption body is arranged on the inner side of the taper-hole noise absorption plate; a GFRC (glass-fiber reinforced cement) noise insulation plate is arranged on the inner side of the hot galvanized steel plate; the environment-friendly fiber sound absorption body and the GFRC noise insulation plate are lapped through keels; a cavity is formed between the keels. Compared with the prior art, the composite sound absorption and noise insulation barrier has the advantages that according to the structure, the effect of sound absorption, noise reduction and attractive appearance can be achieved; the cost is reduced to a larger extent.
Description
Technical field
The utility model relates to sound absorption sound arrester, relates in particular to a kind of compound sound absorption noise barrier.
Background technology
At present, known sound barrier mainly adopts punching galvanized steel plain sheet to make panel, the sound absorption material such as filling glass cotton or foamed aluminium between front plate and backplate.Although the material-structure of this sound barrier can reach the effect of sound absorption, relative cost is higher, from economic angle, is not most scientific selection.
Summary of the invention
The utility model, in order to solve the above-mentioned deficiency of prior art, provides a kind of compound sound absorption noise barrier.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of compound sound absorption noise barrier, it is characterized in that: comprise positive bellmouth abatvoix and the hot-dip galvanizing sheet steel at the back side, bellmouth abatvoix inner side arranges an environmental protection fiber sound absorber, hot-dip galvanizing sheet steel inner side arranges a GFRC sound insulating panel, described environmental protection fiber sound absorber and GFRC sound insulating panel overlap by keel, are provided with cavity between keel.
Described bellmouth abatvoix front is provided with paint film layer.
The thickness of described paint film layer is 0.08mm.
The thickness of described bellmouth abatvoix is 1.35mm.
The thickness of described environmental protection fiber sound absorber is 9mm.
The thickness of described hot-dip galvanizing sheet steel is 1.0mm.
The thickness of described GFRC sound insulating panel is 12mm.
The width of described cavity is 60mm.
The utility model advantage is compared with prior art: structure of the present utility model can be in reaching sound absorption reduction, and good looking appearance has reduced cost largely.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of compound sound absorption noise barrier, it is characterized in that: comprise bellmouth abatvoix 1 and the thick hot-dip galvanizing sheet steel 4 of 1.0mm that 1.35mm is thick, described bellmouth abatvoix 1 front is provided with the paint film layer of 0.08mm, described bellmouth abatvoix 1 inner side arranges the environmental protection fiber sound absorber 2 that a 9mm is thick, hot-dip galvanizing sheet steel 4 inner sides arrange the GFRC sound insulating panel 3 that a 12mm is thick, described environmental protection fiber sound absorber 2 and GFRC sound insulating panel 3 overlap by keel 5, are provided with the cavity 6 of wide 60mm between keel 5.
The utility model utilizes cavity loop around the method sound insulation that absorbs sound of naturally eliminating the noise.
Above-mentioned detailed description of the invention is exemplary, is to be the restriction that this patent is comprised to scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; As long as any being equal to done according to spirit that this patent discloses changes or modify, all fall into the scope that this patent comprises.
