Description
Technical field
The utility model is related to technical field of construction and decoration materials, more particularly, to a kind of abatvoix.
Background technology
With industrial production, communications and transportation, urban architecture development, and the density of population increase, the increasing of home amenity
Many, pollution from environmental noise is increasingly serious, it turn into pollution human society environment a big public hazards, noise have locality, temporarily
When property and it is multiple the characteristics of, noise can not only influence hearing, but also the cardiovascular system to people, nervous system, endocrine
System has a negative impact；With the improvement of living standards, the important reference that absorbing sound and lowering noise has been construction material refers to
Mark.Wooden acoustic board is processed according to Principles of Acoustics exquisiteness, is mainly made up of, can be applied facing, core and sound-absorbing mat
Higher and top grade decoration is required to acoustic enviroment in cinema, music hall, museum, exhibition center, library, family's noise reduction etc.
Place.But its sound-absorbing effect is not very good, need further raising.
The content of the invention
The purpose of this utility model be exactly in order to which the one kind for solving the deficiency of prior art and providing is not only simple in structure, and
And reasonable in design, the good compoiste sound-absorbing board of sound-absorbing effect.
The utility model is to realize above-mentioned purpose using following technical solution：A kind of compoiste sound-absorbing board, its feature
It is, it includes being layered wooden facing and first layer fireproof medium-density fiberboard, the second layer fireproof medium-density fiberboard and elasticity of setting from top to bottom
Noise reduction layer, the wooden panel plate that wooden facing is parallel to each other by polylith is combined, and has groove bit interval between adjacent two wooden decorative panel strips；The
One layer of fireproof medium-density fiberboard is provided with multiple through holes, and the set location of through hole is corresponding with groove position, and second layer fireproof medium-density fiberboard is provided with
Spiral sound-absorption hole corresponding with through hole, makes noise enter the through-hole structure of first layer fireproof medium-density fiberboard through the groove position of wooden facing
Afterwards, into spiral sound-absorption hole, then by the noise reduction of elastic noise reduction layer, the purpose of absorbing sound and lowering noise is realized.
As a further illustration of the above scheme, the wooden facing is in first layer fireproof medium-density fiberboard by adhesive bond
Surface.
Further, the aperture of the spiral sound-absorption hole is more than through hole, forms up-small and down-big sound-absorbing structure.
Further, the elastic noise reduction layer is fixed on the back side of second layer fireproof medium-density fiberboard in the way of being bonded.
The beneficial effect that the utility model can be reached using above-mentioned technical solution is：
The utility model uses mutual by polylith in one layer of the first layer fireproof medium-density fiberboard surface setting with loose structure
The wooden facing of parallel wooden panel plate composition, and it is provided with the back side of first layer fireproof medium-density fiberboard multiple helical silencing holes knots
The second layer fireproof medium-density fiberboard of structure and elastic noise reduction layer, in addition to enough visual effects for keeping good wooden decorative cover, can also have
Effect eliminates noise.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals：1st, wooden facing 2, first layer fireproof medium-density fiberboard 3, second layer fireproof medium-density fiberboard 4, elasticity disappear
Sound-absorbing layer 5, groove position 6, through hole 7, spiral sound-absorption hole.
Embodiment
The technical program is explained in detail below in conjunction with specific embodiment.
As shown in figure 1, the utility model is a kind of compoiste sound-absorbing board, it includes being layered the wooden facing 1 of setting from top to bottom
With first layer fireproof medium-density fiberboard 2, second layer fireproof medium-density fiberboard 3 and elastic noise reduction layer 4, the wood that wooden facing 1 is parallel to each other by polylith
Panel plate is combined, and has groove position 5 to be spaced between adjacent two wooden decorative panel strips；First layer fireproof medium-density fiberboard is provided with multiple through holes 6,
The set location of through hole is corresponding with groove position, and second layer fireproof medium-density fiberboard is provided with spiral sound-absorption hole 7 corresponding with through hole, makes noise
Enter through the groove position of wooden facing after the through-hole structure of first layer fireproof medium-density fiberboard, disappear into spiral sound-absorption hole, then by elasticity
The noise reduction of sound-absorbing layer, realizes the purpose of absorbing sound and lowering noise.Wooden facing is on first layer fireproof medium-density fiberboard surface by adhesive bond.Bullet
Property noise reduction layer is fixed on the back side of second layer fireproof medium-density fiberboard in the way of being bonded.
Further, the aperture of the spiral sound-absorption hole is more than through hole, forms up-small and down-big sound-absorbing structure.
For the ease of installing, a side of first layer fireproof medium-density fiberboard and second layer fireproof medium-density fiberboard is provided with stepped convex
Bar, another side is provided with slot, and raised line is concavo-convex corresponding with slot peace, enables two pieces of adjacent compoiste sound-absorbing boards preferably group
It is integrated.
The utility model compared with prior art, is set using on the first layer fireproof medium-density fiberboard surface with loose structure
The wooden facing that one layer of wooden panel plate being parallel to each other by polylith is constituted, and be provided with the back side of first layer fireproof medium-density fiberboard many
The second layer fireproof medium-density fiberboard of individual helical silencing pore structure and elastic noise reduction layer, except the vision of the good wooden decorative cover of enough holdings
Outside effect, noise can be also effectively eliminated.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.
