Abstract
The utility model discloses a kind of sound insulationg board, including the first glass magnesium board, cork layer and the second glass magnesium board being arranged successively, the first glass magnesium board with a thickness of 6mm, cork layer with a thickness of 8mm, the second glass magnesium board with a thickness of 8mm.The sound insulationg board is according to the propagation characteristic of sound, damping layer selects the damping layer of 8mm, and the speed that sound is propagated in cork is only 500m/s, 1/10th of spread speed about in cement and steel, the spread speed for thus greatly reducing sound reaches certain sound insulation effect；Meanwhile the glass magnesium board with a thickness of 6mm and 8mm is respectively adopted in two surface layers, by considering that sound propagates penetrability and refraction performance in same material, two surface layers are better than using same thickness using the sound insulation effect of different-thickness；The sound insulationg board has good sound insulation effect as a result, and oise insulation factor reaches 44dB.
Description
Technical field
The utility model belongs to a kind of sound insulation product, more particularly, to a kind of sound insulationg board.
Background technique
Current indoor sound insulation mode generallys use the traditional materials such as some general decor planks, and material is mounted on building
On the smallpox of object, wall and the substrate on ground.Following situation often occurs in this mode: density of material is relatively low, and sound transmission loss is poor；Material
Material is not selected according to the sound in place in the fast slow characteristic of propagation of various media, so without apparent deadening；One
As material be all homogenous material, soundproof effect is unobvious.
As the living standard of the people constantly improves, while the demand of spiritual civilization life increases, more and more joys
Happy place is increasing.However as the progress of science and technology, the acoustic pressure that stereo set can generate is also increasing.Due to domestic and international needle
Really few to the research of soundproofing field, the method and data that can refer to are fewer, so most of place is all seldom specially done
Good sound insulation processing.
Utility model content
The purpose of this utility model is to provide a kind of sound insulationg boards for being able to solve at least one of above problem.
One aspect according to the present utility model provides a kind of sound insulationg board, including the first glass magnesium board, soft being arranged successively
Timber layer and the second glass magnesium board, the first glass magnesium board with a thickness of 6mm, cork layer with a thickness of 8mm, the second glass magnesium board with a thickness of
8mm。
The beneficial effects of the utility model are: propagation characteristic of the sound insulationg board according to sound, damping layer selects the damping of 8mm
Layer, the speed that sound is propagated in cork is only 500m/s, 1/10th of spread speed about in cement and steel, from
And the spread speed of sound is greatly reduced, reach certain sound insulation effect；Meanwhile two surface layers are respectively adopted with a thickness of 6mm
With the glass magnesium board of 8mm, by considering that sound propagates penetrability and refraction performance in same material, two surface layers use different thickness
The sound insulation effect of degree is better than using same thickness；The sound insulationg board has good sound insulation effect as a result, and oise insulation factor reaches 44dB.
In some embodiments, cork granulosa is equipped in cork layer, granulated cork is laminated into cork layer.Pass through as a result,
It is pressed into cork granulosa, further enhances the sound insulation effect of cork layer.
In some embodiments, sound insulationg board further includes shock absorption strip, and the first glass magnesium board surrounding opens up fluted, shock absorption strip
It is mounted in groove, the outer edge of shock absorption strip exceeds the outer edge of the first glass magnesium board side.Being equipped with shock absorption strip as a result, can be reduced
The vibration in a noisy environment of entire sound insulationg board, meanwhile, sound insulationg board can be made during installation, improved close between adjacent panels
The planarization of envelope property and splicing.
In some embodiments, the bottom surface of the second glass magnesium board offers multiple mounting holes.It is equipped with mounting hole as a result, it can
To facilitate installation of the sound insulationg board on wall.
In some embodiments, the apparent density of the first glass magnesium board and the second glass magnesium board is 2360~2460kg/m3。
Sound insulation effect can be enhanced using highdensity glass magnesium board as a result,.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the sound insulationg board of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Referring to Fig.1.Sound insulationg board, including the first glass magnesium board 1, cork layer 2 and the second glass magnesium board 3 being arranged successively, the first glass
Magnesium plate 1 with a thickness of 6mm, cork layer 2 with a thickness of 8mm, the second glass magnesium board 3 with a thickness of 8mm；Pass through bonding agent between each layer
It is adhesively fixed.
Wherein, the apparent density of the first glass magnesium board 1 and the second glass magnesium board 3 is 2360~2460kg/m3, it is high density glass
Magnesium plate contains glass fiber reticular cloth in glass magnesium board, and the material of the two is identical, has reached preferable sound insulation effect.
The sound insulationg board of the utility model passes through the serious joy of sound equipment power amplifying device noise emissions mainly for bar, KTV etc.
The applicable acoustic material of relativity is selected to better solve the problem of section public place of entertainment noise emissions disturb residents, especially in happy place
It is that acoustic low-pass part has relatively good performance.
Cork granulosa is equipped in cork layer 2, granulated cork is laminated into cork layer 2, and in actual use, granulated cork is logical
It crosses high pressure to be pressed into cork layer 2, enhances the barrier action of 2 pairs of sound of cork layer.
The sound insulationg board further includes shock absorption strip 4, and 1 surrounding of the first glass magnesium board opens up fluted, and shock absorption strip 4 is mounted on groove
Interior, the outer edge of shock absorption strip 4 exceeds the outer edge of 1 side of the first glass magnesium board.Wherein, shock absorption strip 4 can be rubber strip, Ke Yizeng
Add adjacent sound insulationg board splicing when planarization, and can reduce installation after sound insulationg board entire metope vibratility.
The bottom surface of second glass magnesium board 3 offers multiple mounting holes.Mounting hole can be threaded hole, and threaded hole is evenly arranged on second
Each apex of glass magnesium board 3 can be convenient the installation of sound insulationg board by being equipped with mounting hole, improve installation effectiveness.
In order to further increase the sound insulation effect of the sound insulationg board, sound insulationg board further includes deadening felt, and deadening felt is fixed on second
The bottom of glass magnesium board 3, i.e., between the second glass magnesium board 3 and wall.
In order to facilitate the installation of the sound insulationg board, and the sound insulation effect of sound insulationg board is improved, is fixed in the bottom of deadening felt
