The utility model discloses following beneficial effect has:
(1) the utility model discloses a openly set up the recess at the stand, make the sound insulation body can be followed and openly placed and install between the adjacent coexistence post, the baffle carries on spacingly, make down acoustic baffle, acryl plate and last acoustic baffle can follow stand the place ahead and put into and assemble and prevent to appear the clearance between the acoustic baffle, lead to the syllable-dividing effect variation, avoided the acoustic baffle to place the easy condition of damaging the deformation from the stand top simultaneously and appear, easy operation, installation save trouble, improved the sound insulation effect.
(2) The utility model discloses an install the slope acoustic baffle in the articulated slope support in stand top, use in can the direct mount slope acoustic baffle, can the sound barrier when wind-force is strong at the slope support back mounting spring, reduce the windage of sound barrier device, avoid the sound barrier device to be damaged by strong wind.
Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention relates to a sound barrier device for roadside, which comprises at least two upright posts 1, a sound insulation body 2 installed between two adjacent upright posts 1, and an inclined bracket 3 hinged to the top end of the upright posts 1;
as shown in fig. 4, the column 1 is made of H-shaped steel; the bottom end of the upright post 1 is provided with a base 101; grooves 102 are symmetrically formed in the edge of the front face of the upright post 1; a baffle plate 103 is fixed on the upper surface of the groove 102 through bolts, and two ends of the baffle plate 103 are fixed through bolts;
the sound insulation body 2 comprises a lower sound absorption plate 4, an acrylic plate 5 and an upper sound absorption plate 6 which are sequentially arranged from bottom to top; the upper end surface of the lower sound absorption plate 4 and the lower end surface of the upper sound absorption plate 6 are both provided with a clamping groove 401; the acrylic plate 5 is limited and fixed through a clamping groove 401;
