Abstract
The utility model provides an echo preventive wallboard which comprises an inner wallboard and an outer sound-absorbing layer which are bonded through adhesive glue, wherein the outer sound-absorbing layer comprises wedge-shaped sound-absorbing blocks which are staggered and mutually perpendicular. With the adoption of the arranging mode for the sound-absorbing layer, the contact surface of the sound-absorbing blocks and sound is increased as greatly as possible, so that the sound is absorbed more efficiently; furthermore, sound waves are reflected for a plurality of times after entering the wall body, and the strength of the sound is weakened greatly; and the whole wallboard is simple in structure, small in weight and high in construction efficiency.
Description
Technical field
The utility model relates to a kind of structural lumber, is specially a kind of wallboard that possesses sound-absorbing effect.
Background technology
The sound-absorbing building panel material mostly is wooden greatly at present, the mineral wool material, and the form of structure that has sound-absorption hole, by resonance or sound-absorption hole sound is carried out noise reduction, but for large-scale public place or the environment of very noisy, such sound-absorbing sheet material just shows slightly thin, noise reduction is just so not desirable, in order to strengthen sound-absorbing effect, the somebody has designed the metal abatvoix, mainly be to gather in the bottom surface of a metal plate to have the pyrometric cone of an oval minute aperture at the bottom of being arranged with many awls, establish tool in the end face of metal plate again and be configured as fine undaform surface, and on the undaform surface, also be arranged with the shaping pyrometric cone around the top, corresponding oval minute aperture place; Accordingly, reflected sound wave is collided mutually disturb and the generation decay, such abatvoix cost is too high, and weight is big, and construction is inconvenient.
Summary of the invention
The purpose of this utility model is exactly that a kind of simple in structure, with low cost, anti-echo wallboard of possessing strong sound noise reduction effect will be provided.
A kind of anti-echo wallboard, it comprises inner wall panel, outer sound absorbing layer, and inner wall panel bonds by adhesive glue with outer sound absorbing layer, and outer sound absorbing layer is made up of the sound-absorbing piece of the chock shape of mutual vertical interlaced.
Per two adjacent sound-absorbing pieces, one of them sound-absorbing piece is arranged on the perpendicular bisector of another one sound-absorbing piece.
Per two sound-absorbing pieces are fixedly connected into the T type, and are staggered with contiguous T type sound-absorbing piece.
Inner wall panel is gypsum plank or the wood based panel that has sound-absorption hole.
Described adhesive glue is epoxide-resin glue.
Described sound-absorbing piece is sound-absorbing foam.
Described sound-absorbing tile height is 50cm.
The beneficial effects of the utility model are: adopt the sound absorbing layer of this kind arrangement mode, make the contact surface of sound-absorbing foam and sound increase as much as possible, thus efficient absorption sound more; Secondly, sound wave has also weakened the intensity of sound greatly through reflection for several times after entering this body of wall; Whole wall plate structure is simple, and sheet material and sound-absorbing bulk matter can be selected versatile material for use, and is in light weight, the efficiency of construction height.
