Acoustic board for metro

Abstract

The invention belongs to the technical field of acoustic boards, and discloses an acoustic board for a metro. The acoustic board comprises a base material layer and acoustic holes, the base material layer of the acoustic board is an OSB (oriented structural board), an acoustic board surface is formed in one surface of the base material layer, an acoustic board bottom surface is formed in the other surface of the base material layer, a silencing groove is formed in the acoustic board surface, the acoustic holes distributed at intervals penetrate the bottom surface of the silencing groove, or the acoustic board surface is communicated with the acoustic board bottom surface, a veneering surface is arranged at the upper end of the acoustic board surface, a silencing bottom layer is arranged on the acoustic board bottom surface, and corresponding sides of the base material layer are provided with a connecting convex edge and a connecting groove. The OSB serves as a base material, a simple acoustic structure is added, and the acoustic board not only has fine sound absorbing effects, but also has high strength and dimensional stability.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing panels, in particular to a 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 purpose of the present invention is in order to overcome above-mentioned deficiency, proposes a kind of sound-absorbing panel for subway. [0004] The inventive scheme of the present invention is: the sound-absorbing panel for subway is composed o...
