Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a sound-insulating building exterior wall. Background Art

[0002] With the development of modern industrial technology, more and more houses are being built. In order to improve the quality of living, sound-insulating layers are usually added to the wall panels of the houses.

[0003] In the prior art, bricks are usually used as the exterior wall, and then a rock wool sandwich panel and a gypsum board are arranged outside the brick wall. The rock wool sandwich panel and the gypsum board have a porous structure, can absorb sound energy, and hinder the transmission of sound waves, and have excellent sound-insulating and sound-absorbing properties. The rock wool sandwich panel and the gypsum board are connected to the exterior wall through sponge glue and rivets.

[0008] By arranging a sound-insulating layer composed of a first cement mortar layer, a foamed cement layer and a second cement mortar layer, the building exterior wall has a good sound-insulating effect. The first cement mortar layer abuts against the wall body, and the sound-insulating layer is hung on the wall body through the installation component and the limiting component, which is convenient for replacing the aged sound-insulating layer and improves the disassembly and assembly efficiency of the sound-insulating layer.

[0009] Optionally, the installation component includes an installation plate, a hanging plate and a first adjusting bolt arranged in the first cement mortar layer. The installation plate abuts against the first cement mortar layer. One end of the hanging plate is connected to the top of the installation plate. The other end of the hanging plate is inclined downward along the direction away from the first cement mortar layer. The first adjusting bolt penetrates through the installation plate along the direction perpendicular to the first cement mortar layer and is threadedly connected to the first cement mortar layer.

[0010] Optionally, a first groove adapted to the installation component is formed in the first cement mortar layer. The mounting plate abuts against the bottom of the first groove, and the top side of the hanging plate abuts against the upper wall of the first groove.

[0011] Optionally, the limiting component includes a limiting block and an adjusting member. A second groove is formed on one side of the limiting block close to the wall body. The side of the limiting block away from the wall body abuts against the mounting plate. The top of the limiting block is inclined downward in the direction close to the wall body. The top side of the limiting block abuts against the bottom side of the hanging plate. The adjusting member is used to adjust the distance between the limiting block and the wall body.

The second adjusting bolt penetrates through the limiting block in the horizontal direction and is threadedly connected to the wall body. Two ends of the telescopic spring respectively abut against the bottom of the second groove and the wall body.

[0013] By adjusting the distance between the limiting block and the wall body through the second adjusting bolt and the telescopic spring, the first cement mortar layer abuts against the wall body, reducing the phenomenon that the sound insulation layer warps due to the unevenness of the wall body and the first cement mortar layer, and improving the installation efficiency of the sound insulation layer.

[0014] Optionally, sliding grooves are formed on two sides of the second groove close to each other. A sliding rail adapted to the sliding groove is disposed on the wall body. The limiting block approaches or separates from the wall body through the sliding rail and the sliding groove.

[0015] Optionally, the lower wall of the first groove is inclined downward in the direction close to the wall body. The bottom side of the limiting block abuts against the lower wall of the first groove.

[0016] The beneficial effects of the present utility model are as follows: The sound insulation layer composed of the first cement mortar layer, the foamed cement layer and the second cement mortar layer enables the building exterior wall to have good sound insulation effect. The first cement mortar layer abuts against the wall body. The sound insulation layer is hung on the wall body through the installation component and the limiting component, which is convenient for replacing the aged sound insulation layer and improves the disassembly and assembly efficiency of the sound insulation layer.
