Embodiment

[0036] Example: figure 1 It is a light-weight sound-absorbing wall structure disclosed in the present invention, including a sound-insulating layer keel 1 and a sound-absorbing layer keel 2, and the sound-absorbing layer keel 2 is located outside the sound-insulating layer keel 1 (the sound-insulating layer keel 1 is located on the wall surface 25 and the sound-absorbing layer keel 2). The sound-insulating layer keel 1 and the sound-absorbing layer keel 2 are both light steel keels or wooden keels, and the inner side of the sound-insulating layer keel 1 is separated from the wall by an 8mm thick thin rubber block 7 to prevent solid sound transmission. Rock wool is tightly filled in the grid formed by the keel 1 of the sound insulation layer and the wall surface to form a rock wool layer 8 , and a number of double-layer gypsum boards 9 are laid on the outer side of the keel 1 of the sound insulation layer, and adjacent double-layer gypsum boards 9 Fill the gap with bandage and...

Abstract

The invention relates to the field of architectural acoustics, in particular to a light sound-absorbing jacketed wall structure. The light sound-absorbing jacketed wall structure comprises a sound isolating layer keel fixed to a wallspace, double-layered gypsum boards are fixed to the outer side of the sound isolating layer keel, a sound absorbing layer keel is arranged on the outer side of the sound isolating layer keel, a gap is reserved between the double-layered gypsum boards and the sound absorbing layer keel, two telescopic gratings are arranged in the gap, one side end of each telescopic grating in horizontal direction is fixedly connected to a wall while the other side end is movable, the two telescopic gratings are fixedly connected to opposite two ends of the wall, separately, the two telescopic gratings can cover the whole straight wall space, a plurality of corrugated boards are vertically fixed in an equally spaced manner on each telescopic grating, and the corrugated boards are vertical to the wall space. The sound absorbing effect is improved by increasing density of the corrugated boards on the telescopic gratings, so that the reverberation time is shortened.

Description

technical field [0001] The invention relates to the field of architectural acoustics, in particular to a lightweight sound-absorbing wall structure and a construction method thereof. Background technique [0002] Acoustic engineering is a comprehensive specialty that is closely related to architecture and structure. In terms of technology, it must not only achieve fine and beautiful effects, but also meet the various acoustic technical indicators of the design. As a conference hall, movie theater, gymnasium or performing arts venue, the sound quality effect is very important: good sound quality enables people to hear the speech of the speaker clearly and enjoy the beauty of the music played by the sound reinforcement system; After listening to it, you will feel dizzy and restless, let alone enjoy the beauty of music. At present, many owners have fully realized the importance of acoustic decoration, and require the audio engineering contractor to put forward corresponding re...
