Arc has been plugged and fixed between two adjacent columnss 1 as shown in Figure 1, including several columns 1 in a kind of sound barrier
The sound barrier ontology 2 of shape.Sound barrier ontology 2 includes along the abatvoix 3 and soundproof plate 4 set gradually far from noise direction.This reality
It applies in example, 2 top of sound barrier ontology is only set as arc to be adapted to practical service environment by sound barrier ontology 2.
As shown in Fig. 2, column 1 is made of i shaped steel, the side of column 1 towards sound barrier ontology 2 is fixedly connected with two
A limit plate 5, two sides opposite with column 1 form the card slot 1 cooperated for abatvoix 3 and and sound insulation to two limit plates 5 respectively
The card slot 27 that plate 4 cooperates.Acoustical cotton 8 has been filled between abatvoix 3, soundproof plate 4 and limit plate 5.
As shown in figure 3, card slot 1 and card slot 27 are respectively arranged with rubber hangnail 1 far from the inner wall of limit plate 5, inhale
Soundboard 3 and soundproof plate 4 are respectively arranged with rubber hangnail 2 32, rubber hangnail 1 and rubber hangnail close to one end of limit plate 5
2 32 mutual snap-fits.
As shown in figure 3, abatvoix 3 and the opposite side of soundproof plate 4 and being respectively arranged with structure close to one end of limit plate 5
Identical compressed part 1 and compressed part 2 71.Compressed part 1 includes longitudinal holding tank 611 being provided on abatvoix 3, is held
It receives the compression bar 612 for being embedded in slot 611 and cooperating with holding tank 611, is fixedly connected between compression bar 612 and holding tank 611
Several compressed springs 613.Length when compressed spring 613 is in former long is greater than the distance that abatvoix 3 arrives neighbouring limit plate 5, pressure
The holding tank 611 in tight portion 2 71 is longitudinal to be provided on soundproof plate 4.The setting of rubber hangnail 1 and rubber hangnail 2 32 makes sound-screen
Hinder snap-fit between ontology 2 and limit plate 5, compressed part 1 and compressed part 2 71 make sound barrier ontology 2 and limit plate 5 it
Between compression fit, the two collective effect fixes noise barrier structure.In the present embodiment, compression bar 612 is the thin-walled of a uncovered
Box body, the one of opening is facing towards holding tank 611, and compressed spring 613 is located in compression bar 612, which can reduce compression bullet
The transverse shakiness of spring 613 improves integrally-built stability.
As shown in figure 3, the side that two limit plates 5 mutually deviate from is additionally provided with the limiting slot 51 being adapted to compression bar 612, pressure
The elastic force effect of the compressed spring 613 of tight item 612 is inconsistent with limiting slot 51.Two one end of limit plate 5 far from column 1 are to suction
The surface arc of soundboard 3 and soundproof plate 4 is extended with elastic compression section 52, and elastic compression section 52 is supported with abatvoix 3 and soundproof plate 4
Touching.Limiting slot 51 and 52 collective effect of elastic compression section can reduce be mutually disengaged between sound barrier ontology 2 and limit plate 5 can
Energy property, enhances the stabilization of noise barrier structure.
As shown in Figure 1, being provided with several square grooves 31 on abatvoix 3, it is separate that the notch of groove 31 is located at abatvoix 3
The one side of soundproof plate 4；The bore of 31 notch of groove is greater than the bore of slot bottom, and the side wall of groove 31 is equipped with several for reflecting
The reflection groove 311 of sound wave.31 bottom of groove of upper section offers sound-absorption hole 312 in abatvoix 3, remaining 31 bottom of groove is close
It closes.Be not affected by reflex and the sound wave that weakens by sound-absorption hole 312 reaches soundproof plate 4, soundproof plate 4 towards abatvoix 3 one
Side is provided with several mutually parallel longitudinal convex ribs 41, and the density of the material of one side soundproof plate 4 itself is very big, to remove and from
Sound wave similar in body intrinsic frequency has a deadening, soundproof plate 4 can not sound insulation sound wave can between longitudinally convex muscle 41 phase
Mutually reflection, acoustic wave energy is weakened, to play the role of sound insulation.
As shown in Figure 1, abatvoix 3 is fixedly connected with several rain visors 33 away from the side of soundproof plate 4, rain visor 33 is one by one
It is correspondingly arranged at the notch of the open groove 31 of slot bottom, the angle between 31 notch of rain visor 33 and groove is 40 °, rain visor
33 can effectively reduce that rainwater is attached to abatvoix 3 and 4 surface of soundproof plate causes to corrode to it.Rain visor 33 is far from abatvoix 3
One end be additionally provided with the guiding gutter 331 being folded upward at, the setting of the oblique sound barrier bottom of guiding gutter 331, the lower end of guiding gutter 331
A possibility that end is located at 31 outside of groove, and guiding gutter 331 plays drainage to rainwater, reduces rainwater attachment.
As shown in Fig. 2, in order to be further reduced the possibility that rainwater enters sound-absorption hole 312, sound-absorption hole 312 and 33 phase of rain visor
Pair side wall be extended with to soundproof plate 4 and keep out section 313, rainwater attachment can be further reduced.It is additionally provided at the top of sound barrier ontology 2
By the fixed cover board 9(of screw referring to Fig. 1), prevent rainwater from entering from top.
Specific implementation process: when needing insulating noise, the side where sound barrier acoustic 3 is put towards noise source
It sets, sound wave energy after the reflection of abatvoix 3, the absorption of acoustical cotton 8 and the sound insulation of soundproof plate 4 and reflex is attenuated,
Thus the effect of sound insulation is played.
Sound barrier be arranged in external environment, usually will receive the influence of rainwater weather and reduce the service life, weaken every
Audio fruit.Rain visor 33, guiding gutter 331, the setting for keeping out section 313 and cover board 9 can reduce jointly rainwater and be attached to sound barrier
Surface generates a possibility that corroding or entering sound barrier internal drowning acoustical cotton 8, extends the service life of sound barrier and reduction
A possibility that sound insulation function receives damage.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
