Abstract
The utility model relates to an acoustic board which is formed by bonding a steel board surface layer and the inner layer of an acoustic material board. A pierced steel board is pierced with uniformly distributed acoustic pinholes. The acoustic material board can be a glass wool board hooded with glass cotton fabric, the back surface of the acoustic material board is covered with aluminum foil, and each layer is orderly bonded into the integration. This acoustic board is used for a reporting hall, a broadcasting room, a theatre, etc. serving as a decorative board of an inner wall and a door leaf, has excellent acoustic effect, and improves indoor sound effects.
Description
Technical field
The utility model relates to a kind of abatvoix that is used for Conference Hall, broadcasting room, film and drama field etc. as inner wall panel.
Background technology
Occasions such as Conference Hall, broadcasting room, film and drama field need good acoustics, but the stereo set playing sound is often met wall reflection, repeatedly reflect inside and cause echo, stress, an audibility in the influence.
Summary of the invention
The purpose of this utility model provides a kind of abatvoix with good sound-absorbing effect.
This abatvoix is by punching surface of steel plate layer and the damping material inner cord is bonding forms, and the punching steel plate dashes equally distributed sound-absorbing aperture.Said sound absorber flitch can adopt the conventional material with sound-absorbing effect to make, and can be the block of glass wool internal layer that is wrapped with the glass cotton, and its back side has aluminium foil layer again, they and punching surface of steel plate layer is bonding successively is integral.The side of punching steel plate is bent into the folding groove, so that overlap joint is combined into body of wall in the sound-absorbing mutually.
In this abatvoix, the surface course steel plate can be guaranteed the plate body intensity of this abatvoix, and steel plate dashes the sound-absorbing aperture, and the glass wool internal layer has the good sound absorption effect, and because of glass cotton pine easily falls bits, therefore with glass cotton parcel, wrap with aluminium foil at the back side.This abatvoix is used for the decorative panel as interior body of wall and door leaf such as Conference Hall, broadcasting room, film and drama field, and the room sounding sound wave is absorbed by block of glass wool by the aperture of this abatvoix, can not reflect echogenicity, has fabulous sound-absorbing effect.
Description of drawings
Fig. 1 represents the surface of steel plate structural representation of this abatvoix.
Fig. 2 is the A-A sectional drawing of Fig. 1.
The specific embodiment
Below by Fig. 1 and Fig. 2 embodiment of the present utility model is described.
Fig. 1 represents that the surface course of this abatvoix is a punching steel plate 1, and dashing has equally distributed sound-absorbing aperture 1-1, and the left and right sides of steel plate is folding groove 1-2.
From the cross-section structure of Fig. 2 abatvoix as seen, the steel plate of surface course 1 dashes sound-absorbing aperture 1-1, and its left and right sides is bent into groove 1-2, and the back side that is wrapped with the block of glass wool internal layer 3 of glass cotton 2 has aluminium foil layer 4 again, and each layer is bonding successively and be integral.
