Removable-type subway sound-absorbing board

Abstract

The invention belongs to the technical field of sound-absorbing boards and discloses a removable-type subway sound-absorbing board which is composed of a base material layer and sound-reduction holes. The base material layer of the sound-absorbing board is an OSB (oriented strand board), a sound-absorbing board surface is formed on the base material layer, a sound-absorbing board bottom surface is formed on the other side of the base material layer, sound-reduction grooves are formed in the sound-absorbing board surface, the sound-reduction holes which are distributed at intervals penetrate the bottom surfaces of the sound-reduction grooves, or the sound-absorbing board surface is communicated with the sound-absorbing board bottom surface, an attaching layer is arranged at the upper end of the sound-absorbing board surface, a sound-reduction bottom layer is arranged on the sound-absorbing bottom surface, and the corresponding side edge of the base material layer is provided with a connecting convex edge and a connecting groove. The OSB is taken as the base material, simpleness in the sound-absorbing structure is improved, good sound-reduction effect is achieved, and high strength and stable dimension are achieved.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing panels, in particular to a detachable sound-absorbing panel for subways. Background technique [0002] The Ozon board currently used in the market is mainly used for furniture manufacturing, building materials, decoration materials and packaging materials. Ozon board is made of small-diameter wood and wood core, etc., after planing, deoiling, drying, sizing, paving and hot pressing, it has high strength and dimensional stability. Traditional sound-absorbing panels are usually made of soft sound-absorbing materials. Although they absorb sound, they are not easy to shape, have low strength, and have a single variety. Contents of the invention [0003] The object of the present invention is to propose a detachable sound-absorbing panel for subways in order to overcome the above-mentioned deficiencies. [0004] The invention scheme of the present invention is: a detachable sound-absorbing ...
