The sound insulation wall is also called the sound barrier, current sound insulation barrier, the wall body that the majority is only can the sound insulation, although satisfied effective syllable-dividing purpose, but in hot summer, the wind that sound insulation barrier will flow through has also all blockked down, the comfort level that the resident lives on every side has been influenced greatly, other sound insulation barrier that can ventilate, its sound insulation effect is obvious not enough, most sound wave passes sound insulation wall and still can influence resident's on every side living, it is out-of-date when the strong wind flows simultaneously, can't reduce wind-force decompression, be not convenient for resident's on every side living.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a decompression ventilation sound insulation barrier to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a decompression ventilation sound insulation barrier, includes the support, the inside laminating of support has the frame, the inside bilateral symmetry of frame is opened there is the through-hole, the inside bilateral symmetry of support is opened there is the bolt hole with the through-hole coincidence, the frame passes through the bolt and links to each other with the support is fixed, the inside both sides of frame are opened there is the draw-in groove, the inside joint of draw-in groove has the fixture block, and the fixture block links to each other with the support is fixed, the rigid coupling has the acoustic celotex board in the middle of the inside of frame, the inside bilateral symmetry rigid coupling of frame has the wind-break.

Preferably, the cross section of the wind-break wall is a continuous broken line shape.

Preferably, the inclined plane of the wind-break wall is of a dense small-hole structure, and the vertical plane of the wind-break wall is of a loose large-hole structure.

Preferably, the acoustical panels are of a dense honeycomb structure.

Preferably, the through hole is vertical and long in strip shape, the bolt hole is horizontal and long in strip shape, and the through hole and the bolt hole are overlapped with each other to form a cross shape.

Compared with the prior art, the beneficial effects of the utility model are that: this decompression ventilation sound insulation barrier, the wind-break wall through continuous broken line type can make the sound wave present the indiscriminate form reflection of scattering, can make the collision elimination each other between the sound wave of scattering simultaneously, simultaneously through the intensive little trompil on its inclination's the inclined plane, and with the planar big trompil of ground vertically, can make partly wind straight line flow through, the slope of remaining wind guide is eliminated with most wind collision each other, thereby effectual reduction wind speed wind-force, and the acoustic celotex board in the middle of breaks up the mutual collision elimination with the wind secondary through the honeycomb holes of indiscriminate form of scattering, make the sound wave that sees through the wind-break wall in the downthehole refraction elimination repeatedly of honeycomb simultaneously, greatly increased syllable-dividing effect, make sound insulation barrier can natural draft simultaneously, avoid influencing resident's comfort level around hot summer.
