Abstract
The utility model discloses an assembled sound-adsorbing and sound-insulating barrier composed of a sound-adsorbing resonant cavity and a sound-insulating cavity which are assembled, wherein the resonant cavity is composed of micro-perforation panel and a rear closing plate; a micro-perforation plate which is parallel to the panel can be arranged in the resonant cavity communicated with the atmosphere by micro-pores on the micro-perforation plate; the sound-insulating cavity is composed of a metal or a non-metal panel and a rear closing plate and is filled with sound-insulating materials. The utility model has the advantages of board sound-adsorbing frequency band and good sound-insulating effect; the sound-insulating materials sealed in the sound-insulating cavity can not wet and thus have no influence on sound-insulating effect; the service life of the utility model is extended. The assembled sound-adsorbing and sound-insulating barrier can be widely used for treating road traffic noise and sound insulation of enterprises, factories and equipment.
Description
Technical field
The utility model relates to the Control Noise Pollution technical field, particularly assembly type sound insulation absorbent lined barrier.
Background technology
The sound barrier that is used for road noise improvement at present generally has two kinds, a kind of is the barrier made from metal sheet or non-metal board, this barrier only plays the sound insulation effect, do not absorb acoustic energy, the sound insulation effect is relatively good to the high-frequency noise noise reduction, and in the road traffic noise frequency band range, in, low-frequency noise preponderates, so noise reduction is undesirable; Another kind is as the back shrouding with metal sheet or non-metal board, become cavity with microperforated panel or louvered orifice plate as panel sets, fill sound insulating material within it and constitute sound barrier, this sound barrier is because perforated plate has good acoustically effective, add the defening effect of sound insulating material, make this sound barrier have good noise reduction, but because the road noise barrier all is used in the open, the Changes in weather impermanence, micropore or louvered orifice plate that sleet can see through microperforated panel make moist the sound insulating material in its chamber, thereby influence noise reduction, the sound barrier of having to often change.
The technology contents of utility model
The purpose of this utility model provides a kind of assembly type sound insulation absorbent lined barrier, this barrier had both had the sound insulation effect, also has sound absorption, therefore has good decrease of noise functions, be applicable to the noise of various wavelength, and can not influence the application life of sound barrier because of sound insulating material makes moist, needn't often change sound barrier.This assembly type sound insulation absorbent lined barrier can be used for administering road traffic noise, also can be used for insulating against sound between the sound insulation and equipment between factory circle of enterprise.
For achieving the above object, the technical solution adopted in the utility model: a kind of assembly type sound insulation absorbent lined barrier, comprise resonant cavity and sound insulation chamber, described resonant cavity is made up of micropunch panel and back shrouding, be provided with the microperforated panel that is parallel to the micropunch panel in the resonant cavity, resonant cavity communicates with atmosphere by the micropore on the microwell plate; Described sound insulation chamber is made up of panel and back shrouding, and sound insulation is provided with sound insulating material in the chamber, and this sound insulating material is enclosed in the sound insulation chamber.
Described resonant cavity thickness is 25-100mm, and the quantity of built-in microperforated panel is the 0-4 piece, and the micropore size on described micropunch panel and the microperforated panel is 0.5-4mm, and perforated percentage is 1-30%, and described microwell plate is rough plate or surface plate.
Described sound insulation chamber thickness is 20-130mm, and its panel and back shrouding are metal sheet or non-metal board, and thickness of slab is 0.5-2mm, and the built-in sound insulating material in sound insulation chamber is a kind of of rock wool, glass wool, cotton felt or foamed glue, and its density is 80kg/m
3-150kg/m
3
The operating principle of above-mentioned assembly type sound insulation absorbent lined barrier is: the assembly type absorbent lined barrier that insulates against sound is installed in and is arranged at traffic noise seriously on the connection column of position, both sides, tape track road, the microperforated panel that constitutes resonant cavity on the barrier adopts rough plate or surface plate, its micropore adopts different apertures and perforated percentage, cooperate microperforated panel quantity different in different resonant cavity thickness and the chamber, the sound sucting band of sound barrier is widened, each band noise is had good acoustically effective.Especially to low, midband noise; Insulate against sound in addition the chamber sound insulation factor along with the increase of sound insulation chamber thickness, form sound insulation chamber panel and back shrouding thickness increase, be filled in the increase of sound insulating material density in the sound insulation chamber and increase, the designer can determine various sizes and parameter on the assembly type sound insulation absorbent lined barrier structure according to needed noise reduction index, to satisfy criterion for noise control.
The assembly type sound insulation absorbent lined barrier that the utility model provides is compared with existing sound barrier, has following beneficial effect:
1. excellent noise reduction effect.
Because this assembly type sound insulation absorbent lined barrier had both adopted the sound absorption resonant cavity, had adopted the sound insulation chamber again, sound sucting band is widened, and sound insulation factor was big, had good noise reduction.
2. long service life.
Because the technical solution of the utility model adopts the sound insulation chamber of sealing, make the sound insulating material that is placed in the chamber can not be subjected to the erosion of sleet, thereby can not influence defening effect because of making moist, therefore needn't often change noise barrier.Application life, lengthening was good in economic efficiency.
