Description

Technical Field

[0001] This utility model belongs to the field of building wall technology, specifically a soundproof building wall decoration structure. Background Technology

[0002] Decorative wall treatments refer to the methods of beautifying, modifying, or enhancing the function of building walls through various materials, processes, or design techniques.

[0003] In places such as offices, hotels, and recording studios, the decorative wall structure needs to have sound insulation properties to meet the sound insulation requirements of different locations.

[0004] Currently, after long-term use, it has been found that in the actual construction of traditional walls, the decorative wall structure is in direct contact with the wall or ground. At this time, the sound transmission method is solid-borne sound transmission, and the sound insulation effect of solid-borne sound transmission is poor, resulting in a low overall sound insulation of the wall. Therefore, a soundproof building wall decorative wall structure is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a soundproof building wall decoration structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a soundproof building wall decoration structure of this utility model, comprising: The bottom load-bearing plate is fixedly installed on the ground, located on one side of the wall body; The exterior wall components are joined by mortise and tenon joints above the bottom load-bearing slab, located at the end furthest from the wall itself. The interior wall components are joined by mortise and tenon joints above the bottom load-bearing slab, located at one end close to the wall body. Vibration damping pads are fixedly installed on the outside and top of the exterior and interior wall components to cut off the sound bridge between the components and the corresponding wall surfaces. The bottom load-bearing plate has a gap between itself and the wall body to create a cavity. A decorative wall is fixedly installed on the outside of the outer wall assembly, located at the end away from the wall body. A gap is provided between the outer wall assembly and the inner wall assembly to cut off the sound bridge.

[0007] Preferably, the exterior wall assembly includes a light steel keel A, with rock wool fixedly installed on the inner side of the light steel keel A, an exterior gypsum board A fixedly installed on one side of the light steel keel A, an exterior gypsum board B fixedly installed on the outer side of the exterior gypsum board A, and an exterior gypsum board C fixedly installed on the other side of the light steel keel A.

[0008] Preferably, the interior wall assembly includes a light steel keel B, with glass wool fixedly installed on the inner side of the light steel keel B, an inner gypsum board A fixedly installed on the outer side of the light steel keel B near the wall body, and an inner gypsum board B fixedly installed on the outer side of the inner gypsum board A.

[0009] Preferably, the bottom load-bearing plate has grooves on both sides of the top, and rubber strips are fixedly installed inside the grooves on both sides. Multiple sets of honeycomb grooves are opened at the bottom of the rubber strips, and dovetail strips are fixedly installed at the top of the rubber strips. The dovetail strips on both sides are connected by tenon and mortise joints to dovetail grooves A and B respectively. Dovetail groove A is opened at the bottom of light steel keel A, and dovetail groove B is opened at the bottom of light steel keel B.

[0010] Preferably, a 10mm gap is provided between the light steel keel B and the outer gypsum board C.

[0011] Preferably, the outer gypsum board A and the outer gypsum board B, and the inner gypsum board A and the inner gypsum board B are staggered.

[0012] Preferably, the thickness between the outer gypsum board B and the inner gypsum board B is approximately 220 mm.

[0013] The beneficial effects of this utility model are: This utility model provides a soundproof building wall decoration structure. By setting a 10mm gap between the inner wall component and the outer wall component, the sound bridge is cut off, so that the outer wall component and the inner wall component are no longer in direct contact. At this time, the sound vibration needs to pass through the air layer of the gap, thereby reducing the vibration transmission capacity and increasing the sound insulation by about 8-10dB.

[0014] This utility model provides a soundproof building wall decoration structure. Through the setting of rubber strips and honeycomb grooves, after the ground vibration is transmitted to the bottom load-bearing plate, the honeycomb grooves of the rubber strips will absorb the vibration energy through deformation. When the honeycomb air holes are compressed, the vibration force is consumed. At the same time, the mortise and tenon connection only transmits the support force and does not transmit lateral vibration. Compared with the traditional wall directly on the ground, it can reduce solid-borne sound transmission by more than 30%. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figure 1 - Figure 5 This utility model provides a soundproof building wall decoration structure, including a bottom load-bearing plate 1, an outer wall component 2, an inner wall component 3, and shock-absorbing pads 4. The bottom load-bearing plate 1 is fixedly installed on the ground and located on one side of the wall body 100. The outer wall component 2 is tenon-and-mortise connected to the top of the bottom load-bearing plate 1 and located at the end away from the wall body 100. The inner wall component 3 is tenon-and-mortise connected to the top of the bottom load-bearing plate 1 and located at the end close to the wall body 100. The shock-absorbing pads 4 are fixedly installed on the outer wall component 2 and the inner wall component 3. The outer side and top are used to cut off the sound bridge between the corresponding wall surface. Among them, the bottom load-bearing plate 1 and the wall body 100 are reserved with a gap to create a cavity. The outer wall component 2 is fixedly installed with a decorative wall surface 110, located at the end away from the wall body 100. There is a gap between the outer wall component 2 and the inner wall component 3 to cut off the sound bridge. There is a 10mm gap between the light steel keel B31 and the outer gypsum board C26. The thickness between the outer gypsum board B25 and the inner gypsum board B35 is about 220mm.

[0021] During wall installation, the gap between the bottom load-bearing plate 1 and the wall body 100 is first used to ensure that after the outer wall component 2 is connected to the top of the bottom load-bearing plate 1, there is space between the outer wall component 2 and the bottom load-bearing plate 1, providing a cavity. This cavity can block solid-borne sound transmission, thereby significantly reducing vibration transmission efficiency and increasing sound insulation by about 10dB. At the same time, after the inner wall component 3 is connected to the top of the bottom load-bearing plate 1, the 10mm gap between the inner wall component 3 and the outer wall component 2 cuts off the sound bridge, preventing the outer wall component 2 and the inner wall component 3 from becoming sound bridges. In direct contact, sound vibrations need to pass through the air layer in the gap, which reduces the transmission capacity of vibrations and increases the sound insulation by about 8-10dB. After the outer wall component 2 and the inner wall component 3 are connected to the top of the bottom load-bearing plate 1, the damping pads 4 are fixedly connected to the sides and top of the outer wall component 2 and the inner wall component 3 to cut off the sound bridge on these three sides. At the same time, by connecting the outer wall component 2 and the inner wall component 3 to the top of the bottom load-bearing plate 1, the vibration chain between the outer wall component 2 and the inner wall component 3 and the wall is cut off, reducing the noise level by about 10-15dB.

[0022] Furthermore, such as Figure 5 , Figure 6 As shown, the exterior wall component 2 includes a light steel keel A21, with rock wool 22 fixedly installed on the inner side of the light steel keel A21. An exterior gypsum board A24 is fixedly installed on one side of the light steel keel A21, and an exterior gypsum board B25 is fixedly installed on the outer side of the exterior gypsum board A24. An exterior gypsum board C26 is fixedly installed on the other side of the light steel keel A21. The interior wall component 3 includes a light steel keel B31, with glass wool 32 fixedly installed on the inner side of the light steel keel B31. An interior gypsum board A34 is fixedly installed on the outer side of the light steel keel B31 near the wall body 100, and an exterior gypsum board C26 is fixedly installed on the outer side of the interior gypsum board A34. The inner gypsum board B35 has grooves 11 on both sides of the top of the bottom load-bearing board 1. Rubber strips 12 are fixedly installed inside the grooves 11 on both sides. Multiple honeycomb grooves 13 are opened at the bottom of the rubber strips 12. Dovetail strips 14 are fixedly installed at the top of the rubber strips 12. The dovetail strips 14 on both sides are connected by tenon and mortise to dovetail grooves A23 and B33 on the outer sides. Dovetail groove A23 is opened at the bottom of the light steel keel A21, and dovetail groove B33 is opened at the bottom of the light steel keel B31. The outer gypsum board A24 and the outer gypsum board B25, and the inner gypsum board A34 and the inner gypsum board B35 are staggered.

[0023] Using light steel keel A21 and light steel keel B31 as the main connecting components, dovetail grooves A23 and B33 are respectively used to mortise and tenon connect and fix them to the corresponding dovetail strips 14. After the ground vibration is transmitted to the bottom load-bearing plate 1, the honeycomb grooves 13 of the rubber strip 12 will absorb the vibration energy through deformation. When the honeycomb pores are compressed, the vibration force is consumed. At the same time, the mortise and tenon connection only transmits the supporting force and does not transmit lateral vibration. Compared with the traditional wall directly touching the ground, it can reduce solid-borne sound transmission by more than 30%. Then, rock wool 22 and glass wool 32 are respectively filled inside the light steel keel A21 and light steel keel B31. The outer gypsum board A24 and the inner gypsum board A34 are connected to the outer side of the keel B31 respectively. At the same time, the outer gypsum board B25 and the inner gypsum board B35 are connected to the outer side of the outer gypsum board A24 and the inner gypsum board A34 respectively by the inner wall component 3. The outer gypsum board A24 and the outer gypsum board B25 and the inner gypsum board A34 and the inner gypsum board B35 are staggered and overlapped. This not only improves the strength, but also reduces sound leakage from the gaps. Then, the outer gypsum board C26 is fixedly connected to the other side of the light steel keel A21. At the same time, it is necessary to ensure that a 10mm gap is reserved between the outer gypsum board C26 and the light steel keel B31 to cut off the sound bridge and reduce the amount of vibration transmission.

[0024] Working principle: During wall installation, a pre-existing gap between the bottom load-bearing plate 1 and the wall body 100 ensures that after the outer wall component 2 is connected to the top of the bottom load-bearing plate 1, there is space between the outer wall component 2 and the bottom load-bearing plate 1, providing a cavity. This cavity blocks solid-borne sound transmission, significantly reducing vibration transmission efficiency and increasing sound insulation by approximately 10dB. Simultaneously, after the inner wall component 3 is connected to the top of the bottom load-bearing plate 1, a 10mm gap between the inner wall component 3 and the outer wall component 2 cuts off the sound bridge, preventing direct contact between the outer wall component 2 and the inner wall component 3. At this point, sound vibrations need to pass through the air layer in the gap, thereby reducing the transmission capacity of vibrations and increasing sound insulation by about 8-10 dB. After the outer wall component 2 and inner wall component 3 are connected to the top of the bottom load-bearing plate 1, the damping pads 4 are then fixedly connected to the sides and top of the outer wall component 2 and inner wall component 3, cutting off the sound bridge on these three sides. At the same time, by connecting the outer wall component 2 and inner wall component 3 to the top of the bottom load-bearing plate 1, the vibration chain between the outer wall component 2 and inner wall component 3 and the wall is cut off, reducing the noise level by about 10-15 dB. (This is achieved using light steel keel A21 and light steel keel B3.) 1 is the main connecting element. Dovetail grooves A23 and B33 are respectively used for tenon and mortise connection and fixation with the corresponding dovetail strips 14. After ground vibration is transmitted to the bottom load-bearing plate 1, the honeycomb grooves 13 of the rubber strip 12 absorb vibration energy through deformation. When the honeycomb pores are compressed, the vibration force is consumed. Simultaneously, the tenon and mortise connection only transmits supporting force, not lateral vibration. Compared to traditional walls directly touching the ground, this reduces solid-borne sound transmission by more than 30%. Then, rock wool 22 and glass wool 32 are respectively filled inside the light steel keel A21 and light steel keel B31. Subsequently, the light steel keel A21 and light steel keel B31 are placed opposite each other on the outside. The outer gypsum board A24 and the inner gypsum board A34 are connected to each other on the sides. At the same time, the outer gypsum board B25 and the inner gypsum board B35 are connected to the outer wall components 3 on the outer side of the outer gypsum board A24 and the inner gypsum board A34 respectively. The outer gypsum board A24 and the outer gypsum board B25 and the inner gypsum board A34 and the inner gypsum board B35 are staggered and overlapped. This can improve the strength and reduce sound leakage from the gaps. Then, the outer gypsum board C26 is fixedly connected to the other side of the light steel keel A21. At the same time, it is necessary to ensure that a 10mm gap is reserved between the outer gypsum board C26 and the light steel keel B31 to cut off the sound bridge and reduce the amount of vibration transmission.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
