Sound absorption structure and construction method thereof

Abstract

The invention relates to a sound absorption structure and a construction method thereof. The sound absorption structure is arranged along a wall body of a main body structure, the sound absorption structure comprises a micro-perforated aluminum plate and a glass fiber plate; the micro-perforated aluminum plate is fixed to the main body structure and is parallel to the wall body, and a set distanceis formed between the micro-perforated aluminum plate and the wall body; and the glass fiber plate is fixed to the side, close to the wall body, of the micro-perforated aluminum plate, and a cavity is formed between the glass fiber plate and the wall body. The problem that a sound absorption structure is prone to being affected with damp, and consequently the sound absorption effect is affected is effectively solved, good fireproof and damp-proof performance is achieved, the using range is wide, the structure is simple, and implementation is easy.

Description

Technical field[0001]The invention relates to the field of building construction, in particular to a sound-absorbing structure and a construction method thereof.Background technique[0002]At present, theaters, theaters, swimming pools or large industrial plants and other places need to use strong sound-absorbing materials to control the indoor reverberation time. Usually thicker porous sound-absorbing materials are used to achieve full-range sound absorption in low, medium and high frequencies, and then absorb The sound absorption coefficient of the acoustic material decreases after being damp, and the expected sound absorption effect will be lost. The sound absorption material of the suspended ceiling needs A-level fire protection. Most of the sound absorption materials cannot meet the fire protection requirements, and a few sound absorption materials that can meet the fire protection requirements are medium and low frequency sound absorption The coefficient is small, resulting in e...
