[0002] Building noise isolation devices refer to a series of technical measures and equipment taken to improve the indoor sound environment of buildings and reduce or prevent noise propagation. The main function of these devices is to isolate the energy of noise and vibration transmission paths, thereby reducing indoor noise levels and improving the comfort of living or working environments.

[0003] At present, when dealing with building noise, walls made of materials with good sound insulation performance (such as multi-layer dense materials, lightweight high-damping materials, etc.) are usually used to isolate noise between adjacent rooms or buildings. Soundproof windows: windows that use double or multi-layer glass and fill sound insulation materials (such as inert gas, sound-absorbing materials, etc.) between the glass to improve the sound insulation performance of the window.

[0004] Among them, the patent with publication number CN101755098A discloses a floor impact noise isolation device for construction, which includes a noise absorber and a reinforcing member formed with an inflow hole, the inflow hole is filled with mortar, wherein the inflow hole has a polygonal, circular, elliptical or a combination thereof shape.

[0005] When the structure is in use, the noise isolator is supported by the reinforcement member, and the inflow hole formed in the reinforcement member is filled with mortar, which has excellent strength and prevents cracks from occurring in the mortar layer. In addition, the local load distribution is converted into the surface load distribution, thereby improving the noise isolation performance.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a building noise isolation device comprises a first plate body, and a sound-absorbing and noise-reducing component is arranged on one side of the first plate body.

[0008] The sound-absorbing and noise-reducing component includes a second plate body arranged on one side of the first plate body, a reduction cavity is formed between the second plate body and the first plate body, and an elastic sealing sleeve is embedded in the reduction cavity, the interior of the elastic sealing sleeve is filled with a non-Newtonian fluid, a limiting inclined plate is fixedly arranged on one side of the second plate body and the first plate body, the limiting inclined plate and the reduction cavity are on the same horizontal plane, and the limiting inclined plate matches the reduction cavity, a drainage cavity is formed in the middle of the reduction cavity and between the two silencing chambers, the vertical cross-section of the limiting inclined plate is triangular, and anti-slip pads are arranged on the top and bottom surfaces of the limiting inclined plate.

[0009] It can be seen that in the above technical solution, the first plate body serves as a supporting surface to support the second plate body. At the same time, according to the needs, the appropriate number of the first plate body and the second plate body is increased or decreased, and the two adjacent second plate bodies and the first plate body are installed together in a side-by-side arrangement, and the limiting inclined plate can be extended into the reduction cavity, so that each second plate body and the first plate body can be spliced ​​together, which makes it easy to properly build the device according to the needs and improves the convenience of the device when in use. After the elastic sealing sleeve and the non-Newtonian fluid filled therein, when the first plate body and the second plate body are installed together, the elastic sealing sleeve The plugging sleeve is deformed under force and fills the gap between the attenuation cavity and the first plate body and the second plate body, making it in a sealed state, so that the sound can be gathered in the silencing chamber when it is propagating, and the non-Newtonian fluid filled in the elastic sealing sleeve will continue to be viscous due to the amplitude generated by the sound transmission, which plays the function of elastic support for the elastic sealing sleeve. Combined with the elasticity of the elastic sealing sleeve itself, the non-Newtonian fluid can fill the deformation gap of the elastic sealing sleeve when it is deformed, and then the elastic sealing sleeve can continue to fit with the first plate body and the second plate body, ensuring the sealing and improving the sound-absorbing and noise-reducing effect of the device.

[0010] The first plate body and the second plate body are both provided with a silencer chamber, and a guide frame is clamped in each of the silencer chambers, a plurality of sealing plates are installed in the two guide frames by bolts, a plurality of the sealing plates are arranged side by side, and a plurality of silencer pads are arranged between each two adjacent sealing plates, an attenuation body is fixedly arranged on the plurality of silencer pads, a drainage duct is arranged on the attenuation body, a retention cavity is arranged on one side of the attenuation body, a baffle layer is arranged inside the attenuation body, the retention cavity has an arc-shaped vertical cross-section, a noise reduction core is filled in the retention cavity, and the silencer pad is detachably connected to the sealing plate by bolts.

[0011] An outer protective reduction layer is installed on the second plate body by bolts, and a plurality of drainage inclined plates are inserted in each of the plurality of sealing plates, and each two adjacent drainage inclined plates are arranged oppositely. A silencer plug is provided at one end of the drainage duct, a cushion layer is fixedly provided on one side of the silencer plug, and a limiting body is fixedly provided on the other side of the silencer plug, and the limiting body extends into the drainage duct and is clamped with the drainage duct.

[0012] It can be seen that in the above technical solution, when the noise is transmitted, it is first attenuated by the outer protection attenuation layer, and then enters the sound-absorbing chamber, and is guided through various barrier layers and drainage ducts, so that the sound can be reflected and refracted by the barrier layer, so that it can propagate in the direction of the prescribed propagation path to avoid interference with the surrounding environment. At the same time, when the sound is guided into the attenuation body, it passes through the retention cavity so that the sound flows in the attenuation body, so that it is retained in the retention cavity and is attenuated by the noise reduction core, thereby preventing the transmission of sound energy to reduce noise.

In the present invention, when the non-Newtonian fluid filled in the elastic plugging sleeve is subjected to the amplitude generated by sound transmission, it will remain in a viscous state, playing the role of elastic support for the elastic plugging sleeve. Combined with the elasticity of the elastic plugging sleeve itself, the deformation of the non-Newtonian fluid can fill the deformation gap of the elastic plugging sleeve, and then the elastic plugging sleeve can continue to fit with the first plate body and the second plate body, ensuring the sealing performance and improving the sound-absorbing and noise-reducing effect of the device; In summary, through the corresponding coordinated use of various structures, the sound is guided through various baffle layers and drainage ducts, so that the sound can be reflected and refracted by the baffle layers, so that it can be propagated in the specified propagation path to avoid interference with the surrounding environment.

[0026] As attached Figure 1-7The building noise isolation device shown in the figure guides the sound through the sound-absorbing and noise-reducing components arranged on the first plate body 1 through each barrier layer 206 and the drainage duct 205, so that the sound can be reflected and refracted by the barrier layer 206, so that it can be propagated in a direction according to a specified propagation path to avoid interference with the surrounding environment. At the same time, when the sound is guided into the attenuation body 204, it passes through the retention cavity 207 so that the sound flows in the attenuation body 204, so that it is retained in the retention cavity 207 and is attenuated by the noise reduction core 208, thereby preventing the transmission of sound energy to reduce noise. The elastic sealing sleeve 104 is deformed under force and fills the attenuation cavity 102 and the first plate body 1 and the second plate body 101. The spacing between them makes it in a sealed state, so that when the sound is propagating, it can be gathered in the silencing chamber 2, which is easy to gather and reduce the sound.

Combined with the elasticity of the elastic sealing sleeve 104 itself, the non-Newtonian fluid can fill the deformation gap of the elastic sealing sleeve 104 when it is deformed, and then the elastic sealing sleeve 104 can continue to fit with the first plate body 1 and the second plate body 101, ensuring the sealing performance and improving the silencing and noise reduction effect of the device. The specific structural arrangement of the components is as follows; The sound-absorbing and noise-reducing component includes a second plate body 101 arranged on one side of the first plate body 1, a reduction cavity 102 is formed between the second plate body 101 and the first plate body 1, and an elastic sealing sleeve 104 is embedded in the reduction cavity 102, the interior of the elastic sealing sleeve 104 is filled with a non-Newtonian fluid, and a limiting inclined plate 103 is fixedly arranged on one side of the second plate body 101 and the first plate body 1, the limiting inclined plate 103 and the reduction cavity 102 are on the same horizontal plane, and the limiting inclined plate 103 matches the reduction cavity 102, a drainage cavity 105 is formed in the middle of the reduction cavity 102 and between the two silencing chambers 2, the vertical cross-section of the limiting inclined plate 103 is triangular, and the top and bottom surfaces of the limiting inclined plate 103 are provided with anti-slip pads 106.

[0027] A silencer chamber 2 is provided on the first plate body 1 and the second plate body 101, and a guide frame 201 is clamped in each silencer chamber 2, a plurality of sealing plates 202 are installed in the two guide frames 201 by bolts, the plurality of sealing plates 202 are arranged side by side, and a plurality of silencer pads 203 are arranged between each adjacent two sealing plates 202, a reduction body 204 is fixedly provided on the plurality of silencer pads 203, a drainage duct 205 is provided on the reduction body 204, a retention chamber 207 is provided on one side of the reduction body 204, a baffle layer 206 is provided inside the reduction body 204, the drainage duct 205 and the retention chamber 207, the vertical cross-section of the retention chamber 207 is arc-shaped, the retention chamber 207 is filled with a noise reduction core 208, and the silencer pad 203 is detachably connected to the sealing plate 202 by bolts.

[0028] An outer protective reduction layer 3 is installed on the second plate body 101 by bolts, and a plurality of drainage inclined plates 301 are inserted into the plurality of sealing plates 202, and each adjacent two drainage inclined plates 301 are arranged oppositely, and a silencer plug 302 is arranged at one end of the drainage duct 205, a cushion layer 303 is fixedly arranged on one side of the silencer plug 302, and a limiting body 304 is fixedly arranged on the other side of the silencer plug 302, and the limiting body 304 extends into the drainage duct 205 and is clamped with the drainage duct 205.

[0029] When using the above structure, the staff installs the device on the wall of the building. During installation, the first plate 1 is used as a supporting surface to support the second plate 101. At the same time, according to the needs, the appropriate number of first plate 1 and second plate 101 is increased or decreased, and the two adjacent second plate 101 and the first plate 1 are installed together in a side-by-side arrangement, and the limiting inclined plate 103 can be extended into the reduction cavity 102, so that each second plate 101 and the first plate 1 can be spliced ​​together, which makes it easy to build the device appropriately according to the needs, thereby improving the convenience of the device when in use.

[0030] And when the noise is transmitted, it is first attenuated by the outer protection attenuation layer 3, and then enters the sound-absorbing chamber 2, and is guided by each barrier layer 206 and the drainage duct 205, so that the sound can be reflected and refracted by the barrier layer 206, so that it can be propagated in the direction of the prescribed propagation path to avoid interference with the surrounding environment. At the same time, when the sound is guided into the attenuation body 204, it passes through the retention cavity 207 so that the sound flows in the attenuation body 204, so that it is retained in the retention cavity 207 and is attenuated by the noise reduction core 208, thereby preventing the transmission of sound energy to reduce noise.

Combined with the elasticity of the elastic sealing sleeve 104 itself, the non-Newtonian fluid can fill the deformation gap of the elastic sealing sleeve 104 when it is deformed, and then the elastic sealing sleeve 104 can continue to fit with the first plate body 1 and the second plate body 101, thereby ensuring the sealing and improving the silencing and noise reduction effect of the device.

[0032] Different from the prior art, the present application discloses a building noise isolation device, which guides the sound through each barrier layer 206 and the drainage duct 205, so that the sound can be reflected and refracted by the barrier layer 206, so that it can be propagated in a direction according to a specified propagation path to avoid interference with the surrounding environment. At the same time, when the sound is guided into the attenuation body 204, the sound passes through the retention cavity 207 so that the sound flows in the attenuation body 204, so that the sound is retained in the retention cavity 207 and is attenuated by the noise reduction core 208, thereby preventing the transmission of sound energy to reduce noise. The elastic sealing sleeve 104 is deformed by force and fills the attenuation cavity 102 and the first plate 1 and the second plate 1. The spacing between the plates 101 makes it in a sealed state, so that when sound is propagating, it can be gathered in the silencing chamber 2, which makes it easy to gather and reduce the sound. The non-Newtonian fluid filled in the elastic sealing sleeve 104 will continue to be viscous due to the amplitude generated by the sound transmission, which plays the function of elastic support for the elastic sealing sleeve 104. Combined with the elasticity of the elastic sealing sleeve 104 itself, the non-Newtonian fluid can fill the deformation gap of the elastic sealing sleeve 104 when it is deformed, and then the elastic sealing sleeve 104 can continue to fit with the first plate 1 and the second plate 101, thereby ensuring the sealing and improving the soundproofing and noise reduction effect of the device.
