AI Technical Summary
Traditional building soundproof walls have limited effectiveness in blocking low-frequency noise. Vibrations are easily transmitted through rigid connections, and sound-absorbing materials are prone to settling and deformation, leading to sound wave leakage. Furthermore, there is a lack of coordinated sound absorption design between different layers, making it difficult to balance high-frequency sound absorption and low-frequency damping, resulting in unsatisfactory overall sound insulation efficiency.
The structure employs a combination of damping sound insulation felt, sound insulation board, rock wool board, and paper-faced gypsum board. The damping sound insulation felt suppresses vibration, the sound-absorbing groove matrix and rough surface of the sound insulation board absorb mid-to-high frequency sound waves, the I-shaped components construct cavities to enhance sound insulation, the rock wool board absorbs mid-to-high frequency noise, the supporting mesh stabilizes the structure, and the paper-faced gypsum board provides a smooth finish.
It significantly improves the sound insulation and noise reduction performance, structural stability, durability and construction reliability of the wall, and achieves effective isolation and absorption of low-frequency and high-frequency noise.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soundproof wall technology, specifically relating to a soundproof and noise-reducing wall structure. Background Technology
[0002] Traditional building soundproof walls usually rely on thickening or simply stacking soundproofing layers of a single material. However, brick-concrete structures have limited effectiveness in blocking low-frequency noise, and wall vibrations are easily transmitted through rigid connections, forming sound bridges.
[0003] Conventional sound-absorbing filling materials are prone to settling and deformation due to a lack of effective restraint, causing sound waves to leak from the gaps. While metal vibration damping components added to improve sound insulation performance can alleviate vibration, they significantly increase material and construction costs, and the complex installation process further prolongs the construction period. In addition, existing sound insulation structures lack coordinated sound absorption design between layers, making it difficult to balance high-frequency sound absorption and low-frequency damping, resulting in unsatisfactory overall sound insulation efficiency. Therefore, a sound insulation and noise reduction wall structure is provided to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a sound insulation and noise reduction wall structure to solve the problems existing in the background technology.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0006] A sound insulation and noise reduction wall structure includes a brick wall, a sound insulation component is assembled at the front end of the brick wall, and a paper-faced gypsum board is fixedly assembled at the front end of the sound insulation component.
[0007] The sound insulation component includes a damping sound insulation felt, a sound insulation board, and a rock wool board. The damping sound insulation felt is fixedly assembled at the front end of the damping sound insulation felt, the sound insulation board is fixedly assembled at the front end of the damping sound insulation felt, the rock wool board is fixedly assembled at the front end of the sound insulation board, and the paper-faced gypsum board is fixedly assembled at the front end of the rock wool board.
[0008] The front end of the sound insulation panel is provided with several sound-absorbing grooves, which are evenly distributed in a matrix.
[0009] Preferably, the damping sound insulation felt is fixedly bonded to the brick wall with nail-free adhesive, and a nail is fixedly installed between the damping sound insulation felt and the brick wall.
[0010] Preferably, the sound insulation board is fixedly assembled to the brick wall and the damping sound insulation felt by means of nails.
[0011] Preferably, the front surface of the sound insulation panel is roughened.
[0012] Preferably, the front end of the sound insulation board is fixedly assembled with a plurality of I-shaped parts evenly distributed from left to right, the rear end of the I-shaped parts is thickened, and the rock wool board is fixedly assembled between adjacent I-shaped parts.
[0013] Preferably, a support net is fixedly assembled at the front end of the rock wool board.
[0014] The advantages of this utility model are as follows: This patent effectively suppresses structural vibration and seals gaps through damping sound insulation felt; the sound insulation board, with its sound-absorbing groove matrix and rough surface, significantly absorbs and scatters mid-to-high frequency sound waves; the thickened I-shaped component constructs a regular cavity in front to enhance sound insulation and provide stable support for the rock wool board; the rock wool board fully utilizes the cavity space to efficiently absorb mid-to-high frequency noise and provides thermal insulation and fireproofing; the front support mesh stabilizes the rock wool board and levels the gypsum board; the outermost paper-faced gypsum board serves as the final sound insulation and sealing layer, providing a smooth finish. The wall structure of this patent significantly improves the overall sound insulation and noise reduction performance, structural stability, durability, and construction reliability of the wall.

[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] like Figure 1-3 As shown, the present invention provides a sound insulation and noise reduction wall structure, including a brick wall 1, a sound insulation component assembled at the front end of the brick wall 1, and a paper-faced gypsum board 11 fixedly assembled at the front end of the sound insulation component.
[0023] The sound insulation components include a damping sound insulation felt 21, a sound insulation board 22, and a rock wool board 23. The damping sound insulation felt 21 is fixedly assembled at the front end of the damping sound insulation felt 21, the sound insulation board 22 is fixedly assembled at the front end of the damping sound insulation felt 21, the rock wool board 23 is fixedly assembled at the front end of the sound insulation board 22, and the paper-faced gypsum board 11 is fixedly assembled at the front end of the rock wool board 23.
[0024] Damping sound insulation felt 21 can effectively suppress the transmission of sound due to vibration of the wall structure. It can fill the tiny gaps between the wall and the brick wall to prevent sound from entering through the gaps.
[0025] The front end of the sound insulation panel 22 is fixedly provided with several sound-absorbing grooves 24, which are evenly distributed in a matrix.
[0026] The damping sound insulation felt 21 is fixedly bonded to the brick wall 1 using nail-free adhesive, and nails are also fixedly installed between the damping sound insulation felt 21 and the brick wall 1. The nail-free adhesive provides large-area bonding and sealing, preventing the formation of voids between the damping sound insulation felt 21 and the brick wall 1, while the nails provide mechanical anchoring force. The combination of the two ensures that the damping sound insulation felt 21 is firmly attached to the brick wall 1 and is not easy to fall off.
[0027] The sound insulation panel 22 is fixedly assembled to the brick wall 1 and the damping sound insulation felt 21 by means of nails.
[0028] The front surface of the sound insulation panel 22 is roughened.
[0029] The front end of the sound insulation panel 22 is fixedly equipped with several I-shaped parts 25 evenly distributed from left to right. The rear end of the I-shaped parts 25 is thickened. The rock wool board 23 is fixedly assembled between adjacent I-shaped parts 25.
[0030] The rear end of the I-shaped component 25 is thickened, which forms an air wall between the sound insulation board 22 and the rock wool board 23. The sound is weakened by the air wall, the roughening treatment of the front end of the sound insulation board 22, and the sound absorption groove 24.
[0031] A support mesh 26 is fixedly installed at the front end of the rock wool board 23. The support mesh 26 provides stability support for the front end of the rock wool board 23.
[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
