A kind of sound insulation structure of interior wall of residential room

Abstract

The invention relates to the field of construction, and discloses an inner wall sound insulation structure between houses. The inner wall sound insulation structure between the houses comprises a wallbody, a keel frame is arranged on the inner wall of the wall body, a plurality of sound insulation cotton layers are arranged on the keel frame, and edge pressing supporting seats are arranged between the keel frame and the two adjacent sound insulation cotton layers. Fast locking mechanisms are arranged between the keel frame and the plate pressing supporting seats, sound insulation felt layerscovering the multiple sound insulation cotton layers are arranged on the keel frame, and gypsum boards are arranged on the sound insulation felt layers. The fast locking mechanisms comprise a plurality of fixed pins, rotating lock blocks, elastic parts and push rods. The inner wall sound insulation structure between the houses has the following advantages and effects that the arrangement of the sound insulation cotton layers and the sound insulation felt layers can achieve a good sound insulation effect; firstly, the rotating lock blocks are driven to rotate through the push rods, the fixed pins can be embedded in installation slots of the rotating lock blocks, then the push rods are loosened, the rotating lock blocks rotate under the drive of the elastic parts, fastening parts are fastened on neck parts, so that the effect of quickly installing the sound insulation cotton layers is realized.

Description

technical field [0001] The invention relates to the field of construction, in particular to a sound insulation structure for an inner wall of a house. Background technique [0002] The noise pollution in modern society, especially the harm of indoor noise pollution to health and daily life has gradually attracted people's attention. Therefore, it is necessary to consider the internal sound insulation effect in the design of modern buildings. The sound insulation design can not only improve the indoor sound quality environment, but also It also plays a very important role in noise control. [0003] At present, the authorized announcement number is CN103452210B, and the authorized announcement date is August 5, 2015. The Chinese patent discloses a sound insulation wall for an anechoic room, including a plurality of sound insulation wall modules and two adjacent sound insulation wall modules. The sealing device between them, the sealing device includes a sealing member, the se...

AI Technical Summary

Problems solved by technology

[0004] The sound-insulating wall in the above-mentioned comparative document installs the sound-insulating wall module on the skeleton in the seal, and then fits it on the sound-insulating wall module through the soft material in the seal, and finally compresses the sound-insulating wall with fasteners However, when installing the sound insulation wall on the inner wall, the skeleton needs to be installed on the inner wall. Because the skeleton is roughly in the shape of "I", it is difficult to install the sound insulation wall module between the two skeletons. , at this time, the skeleton and sound insulation wall modules need to be installed one by one, which eventually leads to a more cumbersome installation process
