[0025] The following will describe the embodiments of the present utility model according to its overall structure.
[0026] A vibration and noise isolation structure for a room within a room, as Figures 1 - 3As shown in the figure, it includes a wall 1, a floor 2, and a ceiling 3. One side of the wall 1 is connected to a low-frequency sound-absorbing structure 5 through a wall body shock absorber 6. Glass wool 14 is provided on the surfaces of both the floor 2 and the ceiling 3. A sound insulation pad 13 is provided above the floor 2, a thick steel plate 12 is provided above the sound insulation pad 13, and a waterproof coiled material 11 is provided on the top of the thick steel plate 12. A sound insulation board 9 is provided at the corner between the wall 1 and the floor 2. The low-frequency sound-absorbing structure 5 is connected and provided through a spring shock absorber 7 below the glass wool 14. A gypsum board 4 is provided on one side of the low-frequency sound-absorbing structure 5. The top of the sound insulation board 9 is sealed with asphalt sealant 8 to be sealed from the outside. It is achieved by using materials such as gypsum board 4, low-frequency sound-absorbing structure 5, sound insulation board 9, sound insulation pad 13, and glass wool 14 in combination. The specific steps are as follows: First, install the low-frequency sound-absorbing structure 5 on the wall 1 through the wall body shock absorber 6, and use the angle steel structure 501 to connect adjacent structures, and then attach two layers of gypsum board 4 to its surface; for the floor part, first lay the glass wool 14, and then install the sound insulation pad 13, thick steel plate 12, and waterproof coiled material 11 in sequence. At the same time, fill the sound insulation board 9 into the gap between the wall 1 and the floor, and seal it with asphalt sealant 8; for the sound insulation treatment of the ceiling 3, first lay the glass wool 14 on the surface of the ceiling 3, and then install the low-frequency sound-absorbing structure 5 through the spring shock absorber 7. After connecting with the angle steel structure 501, finally cover it with the gypsum board 4. The entire sound insulation installation process adopts a multi-layer sound insulation structure, introduces an air layer for sound insulation, conducts strict sealing treatment, and comprehensive noise reduction measures, effectively reducing the impact of noise on the surrounding environment and residents, and improving the living comfort.
[0027] Refer to Figure 1 、 Figure 3 As shown in the figure, a folding structure 10 is formed on one side of the waterproof coiled material 11 close to the sound insulation board 9. Adjacent low-frequency sound-absorbing structures 5 are fixedly connected through the angle steel structure 501. The connection tightness and sealing performance between the angle steel frame and the low-frequency sound-absorbing structure 5 are crucial for the sound insulation effect. Good sealing can reduce the leakage of sound waves and improve the sound insulation effect. The acoustic impedance matching degree between the low-frequency sound-absorbing structure 5 and the surrounding air or subsequent structures. Good matching can reduce the reflection of sound waves and improve the efficiency of sound waves entering the sound-absorbing material and being absorbed. Therefore, for the low-frequency sound-absorbing structure 5, its sound insulation performance in the low-frequency band is particularly crucial.
[0028] Refer to Figure 1 、 Figure 2 、 Figure 3, the thickness of the low-frequency sound-absorbing structure 5 is 50 mm, and the size of the angle steel structure 501 used to install the low-frequency sound-absorbing structure 5 is 50x50x4 mm. The 50x50x4 mm angle steel structure 501 is filled with a 50 mm thick low-frequency sound-absorbing structure 5. A 50x50x4 mm angle steel structure 501 filled with a 50 mm thick low-frequency sound-absorbing structure will have better sound insulation performance than an angle steel structure of the same size filled with non-absorbing materials or no filling at all. Especially in the low-frequency band, due to the addition of low-frequency sound-absorbing materials, the attenuation ability of the structure to low-frequency sound waves will be improved. The characteristics such as the density, porosity, and sound absorption coefficient of the low-frequency sound-absorbing materials will directly affect their sound insulation performance.
[0029] Refer to Figure 1 , Figure 2 , Figure 3 , the gypsum board 4 is a double-layer glass fiber-reinforced gypsum board, and the thickness of each layer is 15 mm. The thick steel plate 12 is provided with two layers, and the thickness is 4 mm. The sound insulation pad 13 is of model JF-50 and the thickness is 50 mm. The glass wool 14 has a thickness of 50 mm and a density of 48 Kg / m3. The double-layer 15 mm glass fiber-reinforced gypsum board enhances the sound insulation effect. Compared with ordinary gypsum boards, the reinforced board has a higher density and better sound insulation performance. The 50 mm thick rubber vibration isolation and sound insulation pad 13 and the 50 mm thick glass wool 14 filled with 48 Kg / m3. The 50 mm thick rubber vibration isolation and sound insulation pad 13 is made of natural rubber by vulcanization, contains a reinforcing skeleton to improve the strength and durability of the rubber, has a non-slip surface with convex grid lines designed on the upper part, and a lower part arranged with equally spaced inverted cones. This structure helps to increase the elasticity of the air cushion, improve the vibration isolation and sound insulation effect, and can effectively isolate the vibration and noise transmission on the building structure. The four peripheral edges are designed with concave-convex wedge-shaped grooves for easy installation and can enhance the installation tightness. Due to the use of high-quality rubber and reinforcing skeleton products, it has a long service life. The 50 mm thick glass wool 14 filled with 48 Kg / m3 is made of glass fibers, has good heat insulation and sound absorption performance, is a soft fibrous material, and can be cut and installed according to needs.
[0030] Refer to Figure 1 , Figure 2 , Figure 3, the model of the wall damper 6 is G50QX, the model of the spring damper 7 is BT4-100, the model of the vibration and noise isolation board 9 is FCD-20, and its thickness is 20 mm. The fixed structure G50QX wall damper 6 can effectively reduce structural resonance and noise transmission. The wall damper 6 has a wide frequency response range to cope with vibrations and noises of various frequencies. The material of the damper has an important impact on its performance and service life. The G50QX wall damper 6 is made of high-quality rubber and metal to ensure its good durability and stability. The structural design of the damper is also one of the key factors of its performance. The G50QX wall damper 6 adopts a special design structure, such as a multi-layer composite structure, to improve its damping effect and service life. The 20-mm thickness provides a greater mass density and damping layer thickness compared with thinner sound insulation materials, which helps to enhance the sound insulation effect. Plastic materials usually have good damping performance and can absorb and consume the vibration energy of sound waves, reducing the transmission of sound waves.
[0031] Refer to Figure 1 , Figure 3 , the material of the waterproof coiled material 11 is polymer modified asphalt root-resistant waterproof coiled material, and its thickness is 2 mm. The length of the folding structure 10 is 50 mm. The waterproof coiled material 11 with a thickness of 2 mm has the dual functions of waterproofing and preventing plant roots from penetrating. It can effectively prevent water penetration, keep the building structure dry and stable, and at the same time can resist the penetration of plant roots, protect the building structure from root damage, and thus extend the service life of the building. The polymer modified asphalt root-resistant waterproof coiled material has good high and low temperature resistance performance and can adapt to the climate conditions of different regions to ensure stable waterproof effect in various temperature environments. This coiled material also has excellent corrosion resistance and mold resistance performance and can remain stable for a long time in harsh environments such as humidity, acid and alkali, and is not easily corroded or mildewed.

And the sound insulation board 9 is filled in the gap between the wall 1 and the ground 2, and finally the sound insulation board 9 is sealed with asphalt sealant 8, thus completing the installation operation of the ground sound insulation structure; First, the glass wool 14 is laid on the surface of the ceiling 3, then the low-frequency sound-absorbing structure 5 is installed on the glass wool 14 through the spring shock absorber 7, and then the adjacent low-frequency sound-absorbing structures 5 are installed and connected through the angle steel structure 501.
