Embodiment Construction

[0014] The present invention will be described in further detail below by means of specific embodiments:

[0015] The reference signs in the drawings of the description include: set screw 1, gypsum board 2, soundproof cotton 3, rubber block 4, rubber pad 5.

[0016] The embodiment is basically as figure 1 and figure 2 Shown: double-layer sound-absorbing structure gypsum boards, including two gypsum boards 2, a ring of flanges are provided on the edges of the gypsum boards 2, and the height of the top surface of the flanges perpendicular to the surface of the gypsum boards 2 is 3cm-5cm. If the flange is too high, the structure of the gypsum board 2 is likely to be unstable under stress, and if the flange is too low, the noise cannot be effectively isolated. like figure 1 As shown, the flanges of the two gypsum boards 2 are relatively attached, and a layer of soundproof cotton 3 is arranged in the airtight gap formed by the two gypsum boards 2 . The sound-insulating cotton ...

Abstract

The invention particularly discloses a gypsum board of a double-layer silencing structure. The gypsum board comprises two gypsum board bodies. The edges of the two gypsum board bodies are each provided with a flange. The flanges of the two gypsum board bodies are oppositely attached, and a sealed cavity is formed between the two gypsum board bodies. A layer of soundproof cotton is arranged between the two gypsum board bodies, in a tensional state and suspended in the cavity. The edge of the soundproof cotton is connected between the flanges of the two gypsum board bodies in a clamped mode. According to the scheme, the deficiency of the prior art is made up, the sound insulation function of the gypsum board can be effectively improved by arranging the soundproof cotton between the two gypsum board bodies, and the silencing effect is achieved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a double-layer sound-absorbing structure gypsum board. Background technique [0002] At present, various civil and commercial buildings require more and more room sound insulation effects. In order to achieve a better sound insulation effect, the wall is generally subjected to sound insulation treatment to achieve the desired sound insulation effect. With the development of industry and transportation, noise pollution is becoming more and more serious, which seriously affects people's daily life and health, and the more densely populated and economically developed areas, the more serious the noise pollution is, and now generally used Although the high-grade building gypsum board is light in weight, high in strength, and easy to process, its sound insulation effect is not good. For this reason, it is urgent to develop a kind of gypsum board with good sound insulation effect. ...
