[0065] Embodiment 1:

[0066] See also Figure 1 The present embodiment provides an assembled suspended sound insulation ceiling assembly, which includes: a suspended fixing assembly 100, a sound insulation layer 400, a sound insulation layer 500 and a finishing layer 600. The suspended fixing assembly 100 is fixed to a side of an inner wall 800 close to a floor 700. The suspended fixing assembly 100 is provided with a first installation portion 110, a third installation portion 130 and a fourth installation portion 140 from top to bottom. The sound insulation layer 400 is fixed to the first installation portion 110. A first air interlayer 710 is formed between the sound insulation layer 400 and the floor 700. The sound insulation layer 500 is fixed to the third installation portion 130. A second air interlayer 720 is formed between the sound insulation layer 500 and the sound insulation layer 400. The finishing layer 600 is fixed to the fourth installation portion 140 and the finishing layer 600 is suspended under the floor 700. A third air interlayer 730 is formed between the finishing layer 600 and the sound insulation layer 500.

[0067] In this embodiment, the suspension fixing component 100 is fixed to the side of the inner wall 800 close to the floor 700, and the suspension fixing component 100 is sequentially installed with the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 from top to bottom, so that the suspension fixing component 100 is subjected to force on the inner wall 800, and the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 are not in direct contact with the floor 700, thereby achieving the effect of suspended sound insulation. Suspended sound insulation can effectively cut off the sound bridge, thereby greatly reducing the transmission of vibration and sound, and is used to reduce low-frequency resonance noise, such as the noise generated by footsteps upstairs and moving furniture.

[0068] The sound insulation layer 400 can be used as a floor slab 700 insulation material, significantly improving the energy-saving performance of the building. At the same time, the sound insulation layer 400 can effectively block the transmission of sound waves, and as a sound-absorbing material, it can also significantly absorb the energy of sound waves. The sound insulation layer 500 is used to reduce the noise transmission material layer, which can achieve a better sound insulation effect. The finishing layer 600, as a decoration of the ceiling, has a certain sound insulation effect.

[0069] It is worth noting that a first air interlayer 710 is formed between the sound insulation layer 400 and the floor 700, a second air interlayer 720 is formed between the sound insulation layer 500 and the sound insulation layer 400, and a third air interlayer 730 is formed between the finishing layer 600 and the sound insulation layer 500. The air interlayer isolates the sound by leaving a certain air gap between the two structures and utilizing the reflection, refraction and attenuation of sound waves in the air layer. It has a simple structure, is easy to implement, and has a relatively good isolation effect on low-frequency noise. The sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 all have a good isolation effect on high-frequency noise, and the air interlayer is used in combination with the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 to form a complementary effect, thereby enhancing the overall sound insulation performance.

[0070] For example, when a sound wave enters the sound insulation layer 400 through the air interlayer, due to the different acoustic impedances of the air and the sound insulation layer 400, the sound wave is reflected and refracted again, so that the sound wave energy is further dispersed and absorbed. Alternatively, when a sound wave enters the sound insulation layer 500 through the air interlayer, due to the different acoustic impedances of the air and the sound insulation layer 400, the sound wave is reflected and refracted again, so that the sound wave energy is further dispersed and absorbed. At the same time, the air interlayer itself also has a certain sound absorption effect. When the sound wave propagates in the air interlayer, it interacts with the air molecules, so that the sound wave energy is gradually converted into other forms of energy such as heat energy, thereby further reducing the intensity of the sound wave.

[0071] It is worth noting that the suspended fixing component 100 is provided with a first mounting part 110, a third mounting part 130, and a fourth mounting part 140 from top to bottom. The first mounting part 110 is used to install the sound insulation layer 400, the third mounting part 130 is used to install the sound insulation layer 500, and the fourth mounting part 140 is used to install the decorative surface layer 600. In this way, the sound insulation layer 400 will not take up extra space and will not affect the floor height, so that the entire thickness of the suspended sound insulation ceiling is only 13 cm.

[0072] In this embodiment, the suspended fixing component 100, the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 can all be prefabricated in the factory, and then the manufactured suspended fixing component 100, the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 are transported to the construction site for assembly, which is convenient to install and can greatly shorten the construction period and reduce the construction difficulty.

[0073] Therefore, in this embodiment, the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 are suspended in sequence under the floor 700 through the suspension fixing component 100, so that the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 have no direct contact with the floor 700, which can effectively cut off the sound bridge, thereby greatly reducing the transmission of vibration and sound; at the same time, air interlayers are formed in sequence between the floor 700, the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600, and the air interlayer can isolate low-frequency noise, while the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 have a better isolation effect on high-frequency noise. The combination of the two can complement each other, thereby enhancing the overall sound insulation performance, providing a quieter acoustic space for living or working environments, and is easy to install and beautiful in decoration.

[0074] Specifically, see Figure 2 and Figure 3 The suspended fixing component 100 includes: a suspended fixing profile 200 and a leveling keel component 300. The suspended fixing profile 200 is fixed to the side of the inner wall 800 close to the floor slab 700. The suspended fixing profile 200 is provided with a first mounting portion 110, a second mounting portion 120, a third mounting portion 130 and a fourth mounting portion 140 from top to bottom. The leveling keel component 300 is fixed to the second mounting portion 120. The leveling keel component 300 is used to suspend the finishing layer 600 so as to realize that the finishing layer 600 is suspended under the floor slab 700.

[0075] In this embodiment, the suspended fixed profile 200 is fixed to the inner wall 800 near the floor 700, and the suspended fixed profile 200 is provided with a sound insulation layer 400, a sound insulation layer 500 and a finishing layer 600 from top to bottom, wherein the leveling keel assembly 300 is installed on the suspended fixed profile 200, and the leveling keel assembly 300 is located between the sound insulation layer 400 and the finishing layer 600, and the leveling keel assembly 300 is used to install and fix the finishing layer 600, which is equivalent to the leveling keel assembly 300 being fixed to the inner wall 800 by means of the suspended fixed profile 200. The leveling keel assembly 300 has no direct contact with the floor 700, that is, the finishing layer 600 has no direct contact with the floor 700, which can effectively cut off the sound bridge, thereby greatly reducing the transmission of vibration and sound. This also includes the sound insulation layer 400 and the sound insulation layer 500 installed on the suspended fixed profile 200. The sound insulation layer 400 and the sound insulation layer 500 have no direct contact with the floor 700 and no connection with the roof, so that the sound insulation layer 400, the sound insulation layer 500 and the finishing layer 600 are suspended under the floor 700 to achieve "roof separation" and achieve the ultimate shock absorption effect.

[0076] Specifically, see Figure 4The suspended fixed profile 200 includes: a vertical fixed edge 210, a main load-bearing edge 220, a vertical connecting edge 230, a sound insulation installation edge 240 and a decorative edge 250. The vertical fixed edge 210 is used to be fixed to the side of the inner wall 800 close to the floor 700. The main load-bearing edge 220 is vertically arranged on the vertical fixed edge 210. The main load-bearing edge 220 is provided with a second installation portion 120. The main load-bearing edge 220 is used to install the leveling keel assembly 300. The vertical connecting edge 230 is formed by extending downward from the main load-bearing edge 220. The sound insulation installation edge 240 is vertically arranged on the inner wall 800. The sound insulation installation edge 240 is arranged on the vertical connection edge 230, and the sound insulation installation edge 240 forms a third installation part 130 with the vertical connection edge 230. The sound insulation installation edge 240 is used to install the sound insulation layer 500. The decorative edge 250 is vertically arranged at the end of the vertical connection edge 230. The decorative edge 250, the vertical connection edge 230 and the sound insulation installation edge 240 are connected to form a fourth installation part 140 with a groove structure. The decorative edge 250 is used to install the decorative surface layer 600. The main bearing edge 220 is connected with the vertical connection edge 230 and the decorative surface layer 600 to form a stepped ceiling. The first installation part 110 is arranged at one end of the vertical fixing edge 210 away from the main bearing edge 220.

[0077] In this embodiment, the suspended fixed profile 200 is composed of a vertical fixed edge 210, a main load-bearing edge 220, a vertical connecting edge 230, a sound insulation installation edge 240 and a decorative edge 250. The vertical fixed edge 210 is used to be fixedly connected to the inner wall 800. For example, the vertical fixed edge 210 can be fixed to the inner wall 800 by bolts. The first mounting portion 110 is arranged at one end of the vertical fixed edge 210 away from the main load-bearing edge 220, which is equivalent to that the sound insulation layer 400 can be installed on the top of the vertical fixed edge 210. The main load-bearing edge 220 is vertically arranged on the vertical fixed edge 210. The main load-bearing edge 220 is used to install the leveling keel assembly 300, that is, the leveling keel assembly 300 can be erected on the main load-bearing edge 220. The vertical connecting edge 230 is formed by extending downward from the main bearing edge 220, and a sound insulation installation edge 240 and a decorative edge 250 are sequentially arranged on the vertical connecting edge 230. The sound insulation installation edge 240 is connected to the vertical connecting edge 230 to form a sound insulation slot, and one end of the sound insulation layer 500 can be inserted into the sound insulation slot. The sound insulation layer 500 can be plugged into the sound insulation slot, and the decorative edge 250, the vertical connecting edge 230 and the sound insulation installation edge 240 are connected to form a fourth installation part 140 of a groove structure, which is equivalent to the decorative edge 250, the vertical connecting edge 230 and the sound insulation installation edge 240 being connected to form a decorative slot for plugging with the decorative layer 600, that is, the decorative edge 250 can bend the side of the decorative layer 600 to achieve a beautifying and decorative effect. The vertical connecting edge 230 is perpendicular to the main bearing edge 220 and maintains a certain distance from the inner wall 800, so that the main bearing edge 220, the vertical connecting edge 230 and the finishing layer 600 form a stepped ceiling with beautiful shape, which effectively reduces the sense of spatial oppression and improves living comfort.

[0078] Specifically, see Figure 4 The vertical fixed edge 210 is provided with a first countersunk hole 211, and the first countersunk hole 211 is fixedly connected to the inner wall 800 by bolts.

[0079] In this embodiment, the vertical fixing edge 210 is provided with a first countersunk hole 211, and the first countersunk hole 211 is used to install bolts to achieve a fixed connection with the inner wall 800 through bolts, with a simple structure and convenient installation.

[0080] Specifically, see Figure 2 The leveling keel assembly 300 includes: a main keel 310, a secondary keel 320 and an I-shaped profile 330. The main keel 310 is installed on the second installation portion 120 of the suspended fixing profile 200, the secondary keel 320 is installed below the main keel 310, and the sound insulation layer 500 is installed on the third installation portion 130. The top of the sound insulation layer 500 is fitted and connected to the bottom of the main keel 310, and one side of the sound insulation layer 500 is in contact with the side wall of the secondary keel 320. The I-shaped profile 330 is installed at the bottom of the secondary keel 320, and the I-shaped profile 330 is used to install the decorative surface layer 600.

[0081] In this embodiment, the main keel 310, the secondary keel 320 and the I-shaped profile 330 can all be prefabricated in the factory, and then the manufactured main keel 310, the secondary keel 320 and the I-shaped profile 330 are transported to the construction site for assembly. The installation is convenient, which can greatly shorten the construction period and reduce the construction difficulty. Among them, one end of the sound insulation layer 500 at the edge position is installed in the sound insulation slot formed by the sound insulation installation edge 240 and the vertical connecting edge 230, and the sound insulation layer 500 is fitted and connected to the bottom of the main keel 310, which is equivalent to the sound insulation layer 500 being laid on the bottom of the main keel 310. The other end of the sound insulation layer 500 is in contact with the side wall of the secondary keel 320. Since multiple secondary keels 320 are laid in the entire room, and the sound insulation layer 500 is separated by the secondary keels 320, the sound insulation layer 500 in the middle position is embedded between two adjacent secondary keels 320. In this way, the sound insulation layer 500 will not occupy additional space thickness. Combined with the sound insulation and thermal insulation layer 400 arranged at the top of the vertical fixed edge 210, the sound insulation and thermal insulation layer 400 will not occupy additional space thickness, and the sound insulation and thermal insulation effect can be achieved at the same time, so that the entire thickness of the suspended sound insulation ceiling is only 13 cm, which will not affect the floor height.

[0082] Specifically, see Figure 3 and Figure 5The facing layer 600 includes a plurality of spliced ​​facing panels 610, and the facing panels 610 include a splicing edge 620, which is used to cooperate and connect with the splicing edge 620 of another facing panel 610. The splicing edge 620 includes: a vertical butt joint edge 621, an inwardly inclined edge 622 and a connecting slot 623.
