The acoustic shield wall body is characterized in that the acoustical absorption layer is composed of a centrifugal glass wool layer with medium-high density and a centrifugal glass wool layer with low density, the centrifugal glass wool layer with medium-high density is attached to the acoustical insulation layer, the centrifugal glass wool layer with low density is attached to the surface protective layer and arranged close to acoustic sources. The acoustic shield wall body has good acoustical absorption effect, in particular has high acoustical absorption coefficient to low-frequency noise. The acoustic shield wall body has good acoustical absorption effect, high acoustical absorption coefficient, light weight and beautiful appearance.
Description
Technical field
The utility model relates to a kind of sound insulation enclosure body of wall.
Background technology
As shown in Figure 1, existing sound insulation enclosure wall body structure is made up of following from outside to inside successively: the panel 6 that 2.5mm or 3.0mm steel plate are made (making reinforcing rib with the clod wash equilateral channel steel in the panel), the thick asphalt cement 5 of 5～7mm, rock wool or individual layer centrifugally glass-wool 4, glass fabric 3,1.5mm punched steel plate 2 are formed.Panel 2 is formed soundproof course with asphalt cement 5; Rock wool or individual layer centrifugally glass-wool 4 are formed sound absorbing layer with glass fabric 3; Perforated plate 2 is an armour layer.About about 22 decibels of this kind sound insulation enclosure sound insulation of wall amount, average sound absorption coefficient is about 0.7, Heavy Weight (centre plane density 53kg/m
2).And, with the increase of steel plate thickness, the bending difficulty, the asphalt-coating cream technique is loaded down with trivial details, and perforated plate is not attractive in appearance behind the thick and surperficial rust prevention by applying liquid material lacquer with steel plate, and glass fabric easily stays burr not attractive in appearance after applying, and reinforcing rib is with deficiencies such as clod wash equilateral channel steel section bar Heavy Weights.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of sound insulation enclosure body of wall, its defening effect and sound absorption coefficient height, in light weight and attractive in appearance.
In order to address the above problem, the utility model is by the following technical solutions: a kind of sound insulation enclosure body of wall, comprise the soundproof course, sound absorbing layer and the armour layer that set gradually in order, it is characterized in that: described sound absorbing layer by the middle-high density centrifugally glass-wool, the low-density centrifugally glass-wool is two-layer forms, described middle-high density centrifugally glass-wool and soundproof course are fitted, and the low-density centrifugally glass-wool is fitted near sound source setting and armour layer.Acoustically effective is good, especially to the sound absorption coefficient height of low frequency noise.
In this sound insulation enclosure body of wall, described armour layer comprises perforated plate, is provided with the acoustic foam layer between perforated plate and the low-density centrifugally glass-wool.Acoustic foam further increases acoustic resistance.
In this sound insulation enclosure body of wall, described soundproof course comprises panel and the sound-insulating felt that is bonded on the panel, and sound-insulating felt is arranged between panel and the middle-high density centrifugally glass-wool.Sound-insulating felt not only plays the sound insulation effect, and plays the increase damping loss, the effect that the paddy that coincide is shoaled.
In this sound insulation enclosure body of wall, the steel plate bending that described panel employing thickness is 2.0mm is made, and bending is easy, and is in light weight.
In this sound insulation enclosure body of wall, described perforated plate plating zinc on surface is difficult for getting rusty and attractive in appearance.
The beneficial effects of the utility model are: its sound insulation factor and sound absorption coefficient height, mean transmission loss are 32.5dB (A), and average sound absorption coefficient is 0.9.And the panel bending is easy, in light weight, and armour layer non-corrosive, service time are long.Be applicable to strong noise equipment is eliminated the noise, be particularly useful for the equipment high (as Roots blower) and do the processing of eliminating the noise low-frequency noise.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of existing sound insulation enclosure body of wall;
Fig. 2 is a structural representation of the present utility model;
Among the figure: 1 self-plugging rivet, 2 perforated plates, 3 glass fabric, 4 rock wools or individual layer centrifugally glass-wool, 5 asphalt cements, 6 panels, 7 perforated plates, 8 acoustic foams, 9 low-density centrifugally glass-wools, 10 middle-high density centrifugally glass-wools, 11 sound-insulating felts, 12 panels.
The specific embodiment
As shown in Figure 2, this sound insulation enclosure body of wall comprises the soundproof course, sound absorbing layer and the armour layer that set gradually in order.
Soundproof course comprises the sound-insulating felt 11 of panel 12 and thick 1.2mm.For reducing bending difficulty, panel 12 employing thickness are that the steel plate bending of 2.0mm forms.In the middle of the panel reinforcing rib is set, directly is bent into " U " shape and does reinforcing rib,, alleviate the gross weight of sound insulation enclosure body of wall and can avoid waste of material to replace the section bar of original Heavy Weight with the waste material after the body of wall blanking.Sound-insulating felt 11 usefulness latexes are sticking to be posted on the panel 12, not only increases sound insulation factor, and plays the increase damping loss, the effect that the paddy that coincide is shoaled.
Sound absorbing layer is by 9 two-layer compositions of middle-high density centrifugally glass-wool 10, low-density centrifugally glass-wool.Wherein, middle-high density centrifugally glass-wool 10 is fitted with sound-insulating felt 11, and low-density centrifugally glass-wool 9 is near the sound source setting.This sound absorbing layer sound absorption coefficient height is especially to the sound absorption coefficient height of low frequency noise, good than single-glass cotton or two kinds of identical highdensity glass wool combination acoustically effectives.According to sound source noise spectrum difference, select ρ=24kg/m for use
3And ρ=32kg/m
3Or ρ=32kg/m
3And ρ=60kg/m
3The combination of centrifugally glass-wool, the equipment that type is big (as big Roots blower) is selected ρ=32kg/m for use
3And ρ=60kg/m
3Centrifugally glass-wool combination.
Armour layer is made up of 0.5mm thick zinc-plated perforated plate 7 and acoustic foam 8, acoustic foam 8 adopt the resistance combustion polyurethane foam of thickness 6mm and be arranged on perforated plate 7 and low-density centrifugally glass-wool 9 between.This armour layer is attractive in appearance, increase acoustic resistance, strengthen acoustically effective, (centre plane density 39.5kg/m in light weight
2) and non-corrosive, service time long.
With self-plugging rivet 1 that perforated plate 7 is fixing at last.
