Existing absorbent lined barrier all is the single face sound absorption mostly, and such as adopting perforated plate or panel in front, the back side is adopted dull and stereotyped, and the centre arranges skeleton, and sound absorption material etc. is set between skeleton.These absorbent lined barrier acoustic resistances are little, and acoustically effective is relatively poor, and sound sucting band is also narrower, most importantly adopt the single face sound absorption, can not satisfy the needs under some places or the specific environment.
The utility model content
For overcoming above-mentioned the deficiencies in the prior art, the utility model provides a kind of double-face sound-absorbing barrier, but its double-face sound-absorbing satisfies the Rail Highway construction, industrial premises equipment noise isolation, private residence dwelling house noise reduction, field demands such as electric power coal mining enterprise noise reduction.
For realizing above-mentioned purpose of the present utility model, double-face sound-absorbing barrier of the present utility model comprises: two-sided abatvoix, and it has two sound-absorbing surfaces; And the column of fixedlying connected with two sides of two-sided abatvoix.
Further, also comprise: fixedly connected with described two-sided abatvoix top and respectively to two knuckle abatvoixs of described two sound-absorbings surface two lateral bucklings, with further reduction noise; And respectively with two knuckle abatvoixs, two knuckle columns that side is fixedlyed connected separately.
Preferably, described knuckle abatvoix is two-sided abatvoix or single face abatvoix.
Preferably, described two knuckle abatvoixs have a free end and a link respectively, and described free end is equipped with the sound barrier cap, play the effect of screen sound noise reduction, also can prevent end wear simultaneously.
Preferably, one of described link place spiral-lock and described two buckles that knuckle abatvoix upper surface shape matches play waterproof, breakage-proof and fixation.
Particularly, described buckle is V-shape.
Preferably, described sound barrier cap and described buckle are fixed on the described knuckle column by the tapping screw that is with tarpaulin.
Further, the junction of the junction of described two-sided abatvoix and described column and described knuckle abatvoix and described knuckle column all is pasted with sealing joint strip, further reduces noise.
Preferably, described column and described knuckle column are steel column.
Particularly, described steel column is the H type.
Compared with prior art, double-face sound-absorbing barrier of the present utility model has following advantage:
1) double-face sound-absorbing barrier of the present utility model uses two-sided abatvoix, the barrier both sides is all played the effect of noise elimination noise reduction; Fixedly connected two knuckle abatvoixs make that the noise elimination noise reduction effect is more obvious on two-sided abatvoix top.
2) by the free end at the knuckle abatvoix sound barrier cap is installed, can be shielded the sound noise reduction, can be used for again preventing that free end is because being exposed to outer occur wearing and tearing or damage for a long time.
3) by the buckle of top spiral-lock two knuckle abatvoix junctions, both waterproof, breakage-prooves can be fixed the knuckle abatvoix again.
4) double-face sound-absorbing barrier of the present utility model is in the Rail Highway construction, and the industrial premises noise of equipment is isolated, private residence dwelling house noise reduction, and fields such as electric power coal mining enterprise noise reduction all can be used.
Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment
As Fig. 1 a～shown in Figure 3, the utility model double-face sound-absorbing barrier comprises two-sided abatvoix 2a, and it has two sound-absorbing surfaces, and the column 1a of fixedlying connected with two sides of two-sided abatvoix 2a.
Further, also comprise and fixedlying connected with described two-sided abatvoix 2a top and respectively to two knuckle abatvoix 2b of described two sound-absorbings surface two lateral bucklings, and respectively with two knuckle abatvoix 2b, two knuckle column 1b that side is fixedlyed connected separately, wherein knuckle abatvoix 2b can be two-sided sound-absorbing or single face sound-absorbing.
Particularly, two knuckle abatvoix 2b have a free end and a link respectively, and free end is equipped with sound barrier cap 4, are used for screen sound noise reduction, also are used for preventing end wear simultaneously; Spiral-lock buckle 3 that matches with two knuckle abatvoix 2b upper surface shapes in link place is used for waterproof, breakage-proof and this knuckle part 12 is further fixing, and wherein buckle 3 preferably is V-shape.Sound barrier cap 4 and buckle 3 are fixed on the knuckle column 1b by the tapping screw 5 that is with tarpaulin 6.In order to eliminate the gap noise, all be pasted with sealing joint strip in the junction of two-sided abatvoix 2a and column 1a and the junction of knuckle abatvoix 2b and knuckle column 1b.
In order to fix better and to support two-sided abatvoix 2a and knuckle abatvoix 2b, column 1a and knuckle column 1b can be preferably steel column, and this steel column preferably is the H type.
The operating principle of the utility model double-face sound-absorbing barrier is that two surfaces of two-sided abatvoix 2a all have sound absorption function, can be preferably two-sided blinds type abatvoix, and it is made up of panel and middle sandwich with damping material that the two sides has the blinds fenestra; Two sides of the fixedly connected two-sided abatvoix 2a of column 1a are in order to support and fixed double-sided abatvoix 2a; Fixedly connected two the knuckle abatvoix 2b to two sound-absorbing surface two lateral bucklings in two-sided abatvoix 2a top can further reduce every noise.
With respect to prior art, double-face sound-absorbing barrier of the present utility model is by using two-sided abatvoix 2a, the effect of noise elimination noise reduction is all played on the barrier two sides, and fixedly connected two knuckle abatvoix 2b make that the noise elimination noise reduction effect is more obvious on two-sided abatvoix 2a top; By the free end at knuckle abatvoix 2b the sound barrier cap is installed, can be shielded the sound noise reduction, can be used for again preventing that free end is because being exposed to outer occur wearing and tearing or damage for a long time; By the buckle 3 of upper surface spiral-lock two knuckle abatvoix 2b junctions, both waterproof, breakage-prooves can be fixed knuckle abatvoix 2b again.Double-face sound-absorbing barrier of the present utility model can be used on the Rail Highway construction, and the industrial premises noise of equipment is isolated, private residence dwelling house noise reduction, each field such as electric power coal mining enterprise noise reduction.
