Abstract
The utility model discloses a novel sound barrier. The novel sound barrier comprises a panel, a back plate, a hollow metal sound insulation screen body plate formed by vertical columns, and a transparent sound insulation screen body plate connected with the metal sound insulation screen body plate in a splicing mode. Sound absorption cotton is arranged in the metal sound insulation screen body plate, the metal panel is provided with through holes, and the back plate is a damping steel plate. The novel sound barrier has the advantages of being good in sound insulation effect, convenient to install and use, not prone to damage, low in manufacturing cost, high in strength, small in mass and the like.
Description
Technical field
The utility model belongs to environmental protection noise reduction technology field, is specifically related to a kind of novel sound barrier.
Background technology
Work, the life of unavoidably giving people are brought very large impact by the noise pollution of the generations such as urban road traffic vehicles, railway traffic vehicle and building operations, bring harm even to people's health, road both sides for this reason, especially viaduct both sides, Along Railway and building site are around in order to intercept noise, some sound insulation sound barriers need to be set, to reduce traffic or the interference of building noise to surrounding resident life, and in road design construction in recent years, also force to arrange sound barrier.
At present, the most aluminium thin plate encapsulation of prior art sound barrier damping material is made, and this sound barrier lacks effective sound absorption function, and soundproof effect is undesirable, and aluminium sheet cost is higher, is corroded and affects the life-span.
Utility model content
For solving above-mentioned prior art defect, the purpose of this utility model is to provide a kind of excellent noise reduction effect, the sound absorption compound sound barrier that cost is low.
For achieving the above object, the utility model adopts following technical scheme:
A kind of novel sound barrier, comprise the metal acoustic screen body plate of the hollow of panel, backboard and column composition, and the septum pellucidum sound separating member plate splicing mutually with this metal acoustic screen body plate, in described metal acoustic screen body plate, be provided with acoustical cotton, it is characterized in that: described backboard is damping steel plate, described damping steel plate is provided with die mould groove, and described metal acoustic screen body plate is provided with concavo-convex mounting groove with septum pellucidum sound separating member plate junction, connects each other by concavo-convex mounting groove.
Preferably, described panel is metal louvres plate or perforated plate, to strengthen sound permeability, damping material in it is fully absorbed.
Preferably, described acoustical cotton is coated with hydrophobic sound-absorbing nonwoven.
Preferably, described septum pellucidum sound separating member plate is provided with aluminum alloy outer frame, and the concavo-convex mounting groove on described septum pellucidum sound separating member plate is opened in the upper and lower both sides of aluminum alloy outer frame.
Preferably, described column is H type column, and described septum pellucidum sound separating member plate, metal acoustic screen body plate are arranged in H steel post draw-in groove;
Preferably, in described concavo-convex mounting groove and panel one side of metal acoustic screen body plate with being provided with sealing joint strip between H type column.
Preferably, the acoustical cotton arranging in described metal acoustic screen body plate is with being provided with jump ring between H type column.
By above technical scheme, the utility model has been realized that defening effect is good, integral installation is easy to use, not fragile, cost is low and has been had good intensity and the advantage such as quality is light.
