Double-row keel sound-isolation wall body
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.
