Description

Technical Field

[0001] The utility model relates to the technical field of low-frequency sound insulation, in particular to a low-frequency sound insulation mortar structure. Background Art

[0002] In today's society, with the continuous improvement of economic level, the requirements for quality of life are getting higher and higher. Noise has always troubled people, especially low-frequency noise. Noise below 500 Hz is called low-frequency noise. There are many forms of low-frequency noise, such as the rumbling sound when a car starts its engine, the sound of air conditioners and elevator engines, the sound of people's footsteps, the sound of pile drivers, the "buzzing" sound of bees, etc.; because low-frequency noise propagates slowly in the air, it does not stimulate the human ear much and is difficult to be detected by people; in fact, low-frequency noise is mostly produced by vibration, which is close to the physiological frequency of humans. If exposed for a long time, people are prone to resonate with it, causing nerve and heart discomfort, and severe cases may even lead to internal bleeding.

[0003] The quality law of sound insulation refers to the basic rule that the sound insulation increases with the increase of material mass. The wavelength of low-frequency sound is longer, and very thick materials are needed to effectively absorb and reduce the propagation of sound. Due to thickness limitations, traditional sound insulation materials find it difficult to achieve this, so the low-frequency noise sound insulation effect in buildings is very poor. Utility Model Content

[0004] The purpose of the present invention is to provide a low-frequency sound insulation mortar structure to solve the problems raised in the above background technology.

[0007] Preferably, the wall structure further comprises a shear frame and a first base surface layer, the shear frame is fixedly installed inside the brick wall, and the upper and lower ends of the shear frame are fixedly installed on the inner side of the load-bearing column.

[0008] Preferably, the first base surface layer is fixedly installed at the front end of the brick wall, a first mortar layer is fixedly installed at the front end of the first base surface layer, and a decorative layer is fixedly installed at the front end of the first mortar layer.

[0010] Preferably, the sound insulation mechanism includes a second base surface layer, the second base surface layer is fixedly installed at the rear end of the brick wall, and a second mortar layer is fixedly installed at the front end of the second base surface layer.

[0011] Preferably, heavy balls and elastic micro-beads are fixedly installed inside the second mortar layer, and a finishing layer is fixedly installed at the front end of the second mortar layer.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This low-frequency sound insulation mortar structure has elastic microbeads in the form of irregular spherical particles with a porous cavity structure inside. The surface is glossy and smooth, and the physical and chemical properties are stable. It can be mixed into the second mortar layer as a soft layer. It couples with elastic waves to block the propagation of low-frequency noise.

[0014] 2. This low-frequency sound insulation mortar structure places heavy balls covered with a soft layer in a matrix composed of an overall sound insulation mechanism to form a low-frequency resonance unit. When the frequency of the elastic wave propagating in the matrix is close to the resonance frequency of the resonance unit, the resonance structure unit will have a strong coupling effect with the elastic wave, preventing it from continuing to propagate forward, thereby resulting in the generation of a band gap, thereby achieving small size control of large wavelength and producing a sound insulation effect.

[0032] In this embodiment, preferably, heavy balls 303 and elastic micro beads 304 are fixedly installed inside the second mortar layer 302 , and a finishing layer 305 is fixedly installed at the front end of the second mortar layer 302 .

[0033] Through the above solution, the heavy ball and the surrounding elastic microbeads form a low-frequency resonance unit, which can effectively reduce the propagation of low-frequency noise, and the inner side of the brick wall can be decorated and beautified through the finishing layer.

[0034] When using a low-frequency sound insulation mortar structure of this embodiment, the user grooves the ground in advance, and then ties the steel bars to form a first steel bar group 102 and a second steel bar group 206. After the steel bars are tied, a formwork is supported on the outside and concrete is poured to complete the casting of the base 205 and the load-bearing column 101. After the shaping, the formwork is removed and the brick wall 105 is installed between the load-bearing columns 101. At the same time, the shear frame 201 is installed obliquely on the inner side of the load-bearing column 101 and is embedded in the brick wall 105. After the brick wall 105 is installed, the first base surface layer 202 is applied to the inner side of the brick wall 105. The first base surface layer 202 is applied to the inner side of the brick wall 105. 02 is a mortar material to level the inside and outside of the brick wall 105, and then the first mortar layer 203 is applied on the outside of the first base surface layer 202. The first mortar layer 203 is added with a colloid material and its viscosity is high to facilitate the installation of the decorative layer 204. The decorative layer 204 is an exterior wall decoration material to decorate and beautify the outside of the brick wall 105.

They can act as a soft layer to couple with elastic waves, block the propagation of low-frequency noise, and contain the contained material in the local resonance structure. The heavy balls 303 covered with a soft layer are placed in the matrix formed by the overall sound insulation structure to form a low-frequency resonance unit. When the frequency of the elastic wave propagating in the matrix is close to the resonance frequency of the resonance unit, the resonance structure unit will have a strong coupling effect with the elastic wave, so that it cannot continue to propagate forward, resulting in the generation of a band gap, thereby achieving small size control of large wavelength and producing a low-frequency sound insulation effect. After the second mortar layer 302 is applied, the finishing layer 305 is assembled. The finishing layer 305 is made of ceramic tiles, stones, wood, carpets, plastics and other materials with a thickness of 1mm to 25mm to complete the beautification of the inner side of the brick wall 105.
