Abstract
The utility model discloses a cement -based acoustic board for an acoustic screen. The utility model discloses a silencer pad, the 2nd silencer pad and the 3rd silencer pad, a silencer pad includes noise -damping bowl and panel, and the noise -damping bowl imbeds in the panel, and the noise -damping bowl erects the cross -section and be trapezoidal, and the one end bore towards the noise source on the noise -damping bowl is greater than towards the inboard one end bore of panel, and the 2nd silencer pad goes up to open has the bloop, and the bloop is the honeycomb hexagon, and the 3rd silencer pad includes the bottom plate and inhale the sound cavity, and it be hollow structure to inhale the sound cavity, and just a silencer pad, the 2nd silencer pad, the 3rd silencer pad loop through the glue bonding. The utility model discloses in, through noise -damping bowl, bloop, inhale the silencing function of sound cavity for the repeated elimination of noise process, the amortization is more thorough, and efficiency is higher, and it is not high to have solved current acoustic baffle sound absorption efficiency, the unstable shortcoming of acoustic absorption performance, this acoustic baffle inner structure is loose moreover, and the texture is lighter, copies mechanically conveniently, and the installation is swift.
Description
Technical field
This utility model is related to cement based acoustic board technical field, more particularly, to a kind of cement based sound absorption for sound barrier
Plate.
Background technology
With the fast development of China's economy, the quickly propelling of urbanization process, railway, highway, subway, urban light rail day
Benefit increases, and while being convenient for people to trip, the sound pollution of generation really becomes the atmospheric pollution that continues, water pollution and solid waste
The fourth-largest pollution after thing, thus the governing problem of sound pollution such as has become as at the social problem to be solved, currently for friendship
In the prevention and controls of sound pollution produced by logical facility, setting sound barrier is a kind of relatively effective method, but existing sound
Barrier sound absorption efficiency is not high, and sound absorbing capabilities are unstable, the features such as unit price makes high and easy to install, for this it is proposed that a kind of use
In the cement based acoustic board of sound barrier, for solving the above problems.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and the one kind proposing is used for sound barrier
Cement based acoustic board.
To achieve these goals, this utility model adopts the technical scheme that
A kind of cement based acoustic board for sound barrier, including the first muffler plate, the second muffler plate and the 3rd muffler plate, institute
State the first muffler plate and include noise-damping bowl and panel, noise-damping bowl is embedded in panel, noise-damping bowl vertical section is trapezoidal, court on noise-damping bowl
It is more than towards one end bore inside panel to one end bore of noise source, the second muffler plate has bloop, bloop is in
Honeycomb hexagon, the 3rd muffler plate includes base plate and sound-absorbing cavity, sound-absorbing cavity be hollow structure, and the first muffler plate, second
Muffler plate, the 3rd muffler plate pass sequentially through glue bonding, and the second muffler plate is located between the first muffler plate and the 3rd muffler plate.
Preferably, described silencing net is twice towards panel inner opposite end bore towards one end bore of noise source.
Preferably, described first muffler plate, the second muffler plate and the 3rd muffler plate specification are identical.
Preferably, the cross-sectional area of described bloop is identical.
In this utility model, by noise-damping bowl, bloop, sound-absorbing cavity sound deadening so that noise is through repeating to disappear
Remove, noise reduction is more thorough, in hgher efficiency, it is not high to solve existing acoustic board sound absorption efficiency, the unstable shortcoming of sound absorbing capabilities, and
This acoustic board internal structure is loose, and quality is lighter, copies mechanically conveniently, quick for installation.
Brief description
Fig. 1 be the utility model proposes a kind of cement based acoustic board for sound barrier structural representation；
Fig. 2 be the utility model proposes a kind of noise-damping bowl of cement based acoustic board for sound barrier vertical section illustrate
Figure.
In figure: 1 panel, 2 noise-damping bowls, 3 bloops, 4 sound-absorbing cavitys.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.
With reference to Fig. 1-2, a kind of cement based acoustic board for sound barrier, including face first muffler plate, the second muffler plate and
3rd muffler plate, the first muffler plate includes noise-damping bowl 2 and panel 1, and noise-damping bowl 2 is embedded in panel 1, and noise-damping bowl 2 vertical section is
Trapezoidal, noise-damping bowl 2 is more than towards one end bore inside panel towards one end bore of noise source, the second muffler plate has
Bloop 3, bloop 3 is in honeycomb hexagon, and the 3rd muffler plate includes base plate and sound-absorbing cavity 4, and sound-absorbing cavity 4 is tied for hollow
Structure, and the first muffler plate, the second muffler plate, the 3rd muffler plate pass sequentially through glue bonding, the second muffler plate is located at the first noise elimination
Between plate and the 3rd muffler plate, noise-damping bowl 2 is twice towards panel 1 inner opposite end bore towards one end bore of noise source,
First muffler plate, the second muffler plate and the 3rd muffler plate specification are identical, and the cross-sectional area of bloop 3 is identical.
Noise is introduced into noise-damping bowl 2, by the noise reduction sound absorption of noise-damping bowl 2, so that noise is reduced and reduces, the noise of minimizing
Enter back in bloop 3, by the noise reduction sound absorption of bloop 3, make noise reduce reduction again, tend to disappearing, if also having
Partial noise is not wholly absent, and is again introduced in sound-absorbing cavity 4, noise reduction sound-absorbing again, is made by such noise reduction sound-absorbing that repeats
With, it is that noise eliminates more thoroughly, in hgher efficiency.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any those familiar with the art in the technical scope that this utility model discloses, according to this practicality
New technical scheme and its utility model design in addition equivalent or change, all should cover in protection model of the present utility model
Within enclosing.
