Example Embodiment

[0016] The implementation of the present invention will be described in detail below with reference to the accompanying drawings and embodiments, so as to fully understand how the present invention applies technical means to solve technical problems and achieve the realization process of technical effects and implement them accordingly. The embodiments of the present application and the combination of the various features in the embodiments without conflict are within the protection scope of the present invention.

[0017] The double-row keel sound insulation wall of the embodiment of the present application is mainly based on a double-row Z-shaped keel, and a plasterboard layer is provided on both sides of the double-row Z-shaped keel. There is also a plasterboard layer and sound insulation felt between them. The cavity between the two adjacent gypsum board layers is filled with rock wool, and the thickness of the rock wool is smaller than the thickness of the cavity where it is...

Abstract

The invention discloses a double-row keel sound-isolation wall body, which overcomes the defects of poor sound isolation effect, excessive indoor space occupation, high construction cost and insufficient technical schemes of good-sound-isolation structures of conventional sound-isolation wall bodies. The wall body comprises double rows of Z-shaped keels (1), wherein a first paper surface gypsum board layer (2) is arranged at the first side of the double rows of Z-shaped keels (1); a second paper surface gypsum board layer (3) is arranged at the second side of the double rows of Z-shaped keels (1); a third paper surface gypsum board layer (4) and sound-isolation felt (5) are arranged between the double rows of Z-shaped keels; a first cavity formed between the first paper surface gypsum board layer (2) and the third paper surface gypsum board layer (4) is filled with rock wool (6); a second cavity formed between the second paper surface gypsum board layer (3) and the third paper surface gypsum board layer (4) is filled with rock wool (6); and one row of Z-shaped keels is arranged in each of the first cavity and the second cavity. The double-row keel sound-isolation wall body provided by the embodiment of the invention has a good sound isolation effect on both low-frequency sound and high-frequency sound.

Description

technical field [0001] The invention relates to a sound-insulating wall, in particular to a double-row keel sound-insulating wall. 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. [0003] Existing gypsum board walls are subjected to high sound insulation treatment, often from the perspective of increasing the number of gypsum board layers, increasing the section size of the keel, and increasing the number of keel rows. The sound insulation effect of the wall obtained by these traditional structures is not high, and generally can be It is suitable for buildings with low sound insulation requirements such as residential buildings. If buildings need to achieve better sound insulation effects, and special places have ultra-high sou...
