Abstract
The utility model discloses a full frequency band noise barrier that is a rectangular board. The right side of the board is provided with at least one raised rib that parallels any side of the board. Each raised rib is provided with a tunnel-like hollow space, and the upper and lower sides of the hollow space have a plurality of through holes. The side of the board with the raised rib is provided with a plurality of through holes that penetrate the board. The utility model can realize the absorption of noises at the full frequency band, because the hollow raised rib diffuses sound wave, the through holes on the upper and lower sides of the hollow space can increase the sound absorption factor for medium and high acoustic frequency, and the through holes have the function of absorbing sound. The utility model has the advantages of environment friendliness, fine look, gracefulness, and broad applicability to various occasions with high requirement for sound absorption.
Description
Technical field
The utility model relates to building finishing sheet material, is specifically related to a kind of full range band acoustical board.
Background technology
Timber is building finishing industry common used material, but the sheet material on plane can produce complicated reflection to sound, and the effect of sound insulation sound absorption is relatively poor.Therefore for the occasion of the good sound insulation acoustically effective of needs, traditional way generally is to carry out sound-absorbing or sound insulation with the glass wool goods, but its still exist sound-absorbing effect not ideal enough with the problem that is unfavorable for environmental protection.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of full range band acoustical board simple in structure is provided, and it can carry out the sound absorption of full range band to sound, and is satisfactory for result.
For achieving the above object, the technical solution of the utility model is as follows: full range band acoustical board is a rectangle sheet material; The front of described sheet material be provided with at least one with the parallel fin of the arbitrary side of sheet material, each fin has a tunnel type hollow bulb, on this hollow bulb face and below have some through holes, and have some through holes that run through sheet material on the sheet material of fin side.
Above-mentioned through hole is offered with array way.
Many two of above-mentioned fin, and be provided with at interval.
The width of above-mentioned fin is identical.
Many three of above-mentioned fin, and spaced set.
Spacing between above-mentioned wantonly two fins is less than or equal to the width of fin.
Place damping material in the above-mentioned hollow bulb.This damping material can be foam, or the cellulose acoustical cotton, or glass wool.
The bottom surface of the above-mentioned sheet material sound-absorbing material layer of applying ointment or plaster.This sound-absorbing material layer can be nonwoven, or absorbent rug.
The utility model is owing to adopt said structure, its hollow fin has diffusion function to sound wave, and increase the sound absorption coefficient of alt frequency and low frequency above the hollow bulb respectively with following through hole, through hole then has acoustically effective, thereby reach full range band sound absorption to sound, and be beneficial to environmental protection and elegant in appearance, can be widely used in the occasion that the sound insulation sound absorption is had relatively high expectations.
Description of drawings
Fig. 1 is a Facad structure schematic diagram of the present utility model;
Fig. 2 is a sectional structure schematic diagram of the present utility model.
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a rectangle sheet material 1, has some length along sheet material on the front of rectangle sheet material 1 and equidistantly is provided with at interval and the rectangular hollow fin 11 parallel with the sheet material long side, and the hollow bulb 111 of fin 11 is a tunnel type.Offer some through holes 112 with array way respectively below face reaches on this tunnel type hollow bulb 111.The width of fin 11 equate and two fins between spacing less than the width of fin.Offer some through holes 12 that run through sheet material on the sheet material 1 of fin side, these some through holes are equidistantly offered along direction one row that are provided with of fin.The bottom surface of rectangle sheet material 1 sound-absorbing material layer 2 of applying ointment or plaster, this sound-absorbing material layer is a nonwoven, or absorbent rug.
The fin of the utility model has diffusion function to sound, and can increase the sound absorption coefficient of alt frequency and low frequency above the fin hollow bulb respectively with following through hole; Through hole on the sheet material then has acoustically effective; Cooperate sound-absorbing material layer again, then effect is more obvious.Damping material can be placed in the fin hollow bulb,, sound-absorbing effect can be further strengthened as foam, cellulose acoustical cotton and glass wool etc.
In addition, can change the sound absorption frequency of sheet material, and through hole can rule or irregular offering, and so can satisfy the sound isolation requirement of different occasions by the pore size that changes through hole.Also have, sheet material can adopt the environment-friendly materials of lightweight, fire-retardant, insect protected, waterproof to make.
The foregoing description only is a better embodiment of technical solutions of the utility model, and that embodiment of the present utility model can have is multiple, describes in detail no longer one by one at this.
