Abstract

The utility model relates to the technical field of sound-insulating wallboards and discloses a gypsum-based sound-insulating wallboard which comprises a wallboard body and a sealing frame arranged on four sides of the wallboard body, wherein the wallboard body comprises two core boards arranged in the sealing frame, sound-absorbing components are arranged on the opposite sides of the two core boards, a gypsum board is fixed on one end face of the sound-absorbing component, which is far away from the core boards, and the gypsum board is in a flush state with the end face of the sealing frame. The gypsum-based sound insulation wallboard forms a multiple cooperative sound insulation barrier through the mass effect and rigidity of the metal plate, the sound bridge blocking effect of the vacuum cavity, the sound wave scattering and guiding effect of the arc-shaped reflecting plate, the vibration damping energy consumption effect of the sound insulation damping glue and the sound absorption conversion effect of the sound absorption material, covers different paths and different frequencies of sound wave propagation, effectively inhibits the energy transmission of medium-low frequency sound waves, and is provided with sound insulation measures symmetrically, so that sound insulation treatment can be carried out simultaneously from two sides, and the sound insulation effect is good.

Description

Gypsum-based sound insulation wallboard Technical Field The utility model relates to the technical field of sound insulation wallboards, in particular to a gypsum-based sound insulation wallboard. Background Along with the acceleration of the urban process and the improvement of the building density, the noise pollution problem is increasingly serious, and particularly, the middle-low frequency noise (such as traffic noise, mechanical equipment vibration sound and the like) has strong penetrability and slow attenuation, so that the indoor environment comfort is obviously influenced. The traditional gypsum-based wallboard is used as a building partition wall material, has certain sound insulation performance, but has single sound insulation mechanism, mainly depends on material density or simply overlaps a sound absorption layer, is difficult to form effective isolation for middle and low frequency noise, has poor sound insulation effect, and is difficult to meet increasingly-improved sound environment requirements. Disclosure of utility model The utility model is provided in view of the problems that the prior sound insulation mainly depends on material density or simply overlaps a sound absorption layer, is difficult to form effective isolation for medium-low frequency noise and has poor sound insulation effect. The utility model aims to provide a gypsum-based sound insulation wallboard, which aims to effectively isolate middle and low frequency noise by matching multiple sound insulation measures. In order to solve the technical problems, the utility model provides the technical scheme that the gypsum-based sound insulation wallboard comprises a wallboard body and sealing frames arranged at four sides of the wallboard body; The wallboard body is including installing at two core boards inside sealed frame, two the sound subassembly is all installed to the opposite sides of core board, the one end face that the sound subassembly was kept away from the core is fixed with the gypsum board, and the gypsum board is in flush state with the terminal surface of sealed frame. As an improved technical scheme, a vacuum cavity is formed between the two core plates and the inner wall surface of the sealing frame, and the core plates are metal plates. As an improved technical scheme, arc-shaped reflecting plates are arranged on two sides of the inside of the vacuum cavity, and the reflecting plates on two sides are arranged in opposite and staggered states. As an improved technical scheme, inhale the sound subassembly including fixing the damping layer in the core one side of keeping away from the reflecting plate, the damping layer is the damping that gives sound insulation and glues, the damping layer is kept away from the terminal surface of core and is fixed with and inhale the sound cotton, inhale the sound cotton terminal surface of keeping away from the damping layer and be fixed with the acoustic celotex board. After the technical scheme is adopted, the utility model has the beneficial effects that: According to the utility model, through the mass effect and rigidity of the metal plate, the sound bridge blocking effect of the vacuum cavity, the sound wave scattering and guiding effect of the arc-shaped reflecting plate, the vibration damping energy consumption effect of the sound-insulation damping glue and the sound absorption conversion effect of the sound-absorbing material, a multiple synergistic sound-insulation barrier is formed, different paths and different frequencies of sound wave propagation are covered, the energy transmission of medium-low frequency sound waves is effectively inhibited, and the symmetrically arranged sound-insulation measures can be adopted to simultaneously perform sound insulation treatment from two sides, so that the sound-insulation effect is good.
