Abstract
The invention provides an acoustic panel with a buffer function. The acoustic panel with the buffer function comprises the acoustic panel and a buffer member; the panel bottom, side face and end head of the acoustic panel are connected to the buffer member. The related acoustic panel with the buffer function has good sound absorption effect.
Description
Technical field
The present invention relates to a kind of abatvoix with pooling feature, belong to railway technology field.
Background technology
The controlling factor analysis of sound absorption qualities is known, and grooved surface texture can improve abatvoix sound-absorbing effect, but affects not obvious; Wedge absorber can improve the deficiency of track acoustic board in low frequency part sound absorption qualities, and namely with the increase of the length of wedge, its cut-off frequency reduces, and the sound-absorbing effect of low frequency strengthens.The air layer of abatvoix behind and between rigid walls, the performance of material thickness increase can be defined as on the impact of sound-absorbing effect, this can improve the sound-absorbing effect of abatvoix to low frequency, more more economical than the thickness or density that increase merely material, improve the degree of depth of cavity, height and the width of absorption peak can be improved, and peak value is moved to low frequency direction.
Summary of the invention
The invention provides a kind of abatvoix with pooling feature, make sound-absorbing effect good.
For solving above technical problem, the invention provides following technical scheme: a kind of abatvoix with pooling feature, comprises abatvoix and bolster, at the bottom of described abatvoix plate, side, termination connect bolster.
Further, the material of described bolster is rubber.
Further, the material of described bolster is neoprene and acrylonitrile-butadiene rubber.
Further, adopt zinc-plated nail that bolster is fixed on abatvoix surface.
This abatvoix with pooling feature that the present invention relates to, makes sound-absorbing effect good.
Accompanying drawing explanation
Fig. 1 is a kind of abatvoix sectional view with pooling feature of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of abatvoix with pooling feature, comprises abatvoix 1, bolster 2 and bolster 3, at the bottom of described abatvoix plate, side, termination connect bolster.
The material of described bolster is rubber.
The material of described bolster is neoprene and acrylonitrile-butadiene rubber.
Adopt zinc-plated nail that bolster is fixed on abatvoix surface.
At the bottom of abatvoix plate, side, termination padded coaming be rubber, its composition is mainly neoprene and acrylonitrile-butadiene rubber etc., plate bottom buffering part is of a size of 95mm × 95mm × 20mm, and side bolster is of a size of 600mm × 70mm × 30mm, and termination bolster is of a size of 780mm × 30mm × 30mm.Neoprene and acrylonitrile-butadiene rubber to have from fire from putting out, oil resistivity is good, the features such as good endurance, are applicable to the large and environment that fire protection requirement is high of subway greasy dirt.
Detailed description of the invention of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
