Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of soundproof board, specifically relates to a multilayer soundproof board. BACKGROUND

[0002] In modern society, with the improvement of people's living standards and the pursuit of life quality, the quietness of living and working environment is also increasingly high. As an effective acoustic material, soundproof board has been widely used in the field of building decoration.

[0003] However, the existing soundproof board has some shortcomings. On the one hand, the traditional soundproof board has defects in the overall structure, and the connection between its various components is not stable enough, which is prone to looseness, deformation and other problems during use, affecting the sound insulation effect and service life. On the other hand, many existing soundproof boards adopt single-layer structure design, which has certain limitations in sound insulation effect and structural strength. Single-layer structure cannot effectively absorb and block the propagation of sound, resulting in poor sound insulation effect; at the same time, the strength of single-layer structure is relatively weak, and it is difficult to withstand large pressure and vibration, which is easy to damage.

[0004] In addition, some existing soundproof boards also have shortcomings in the selection and application of sound-absorbing materials. The sound-absorbing materials used by some soundproof boards have unsatisfactory sound-absorbing performance, which cannot fully absorb sound energy, thereby affecting the overall sound insulation effect. Moreover, the appearance design of some soundproof boards is relatively simple, lacking aesthetic appearance, which cannot meet the diversification demand of people for indoor decoration.

[0005] Therefore, the present application provides a multilayer soundproof board to solve the above problems. CONTENT OF THE UTILITY MODEL

[0006] In order to overcome the defects of the prior art, the purpose of the utility model is to provide a multilayer soundproof board.

A plurality of docking card slots in the shape of a "rich" character are equidistantly arranged on the outer surface of the sound-absorbing board. The docking convex block inside each independent decorative board is correspondingly clamped inside the docking card slot at this position.

[0012] Preferably, both the central filling layer and the filling block are made of sound-absorbing cotton material.

[0013] Preferably, the independent decorative board and the sound-absorbing board are also connected by an adhesive method on the surface.

[0014] The beneficial effects of the present utility model are reflected in:

[0019] Adopting a double-layer mounting keel frame to improve the sound insulation effect and structural strength:

[0020] The design of the double-layer keel frame can further improve the overall structural strength compared with the traditional single-layer design, providing a stable clamping and fixing framework for the central filling layer.

[0021] The central filling layer can absorb the vibration between the inner mounting keel frame and the outer mounting keel frame, reduce the transmission of sound, and improve the sound insulation effect.

[0022] The sound-absorbing cotton material filling blocks filled in the grid-shaped space inside the inner mounting keel frame cooperate with the central filling layer to jointly play a sound-absorbing role, further improving the sound insulation performance of the whole sound-insulating board.

[0038] Please refer to the drawings in the description Figures 1-5 The utility model provides a multilayer sound insulation board:

[0039] Structure of multilayer sound insulation board

[0040] Mounting frame

[0041] The mounting frame 1 serves as the external frame of the entire multilayer sound insulation board and plays a key role in fixation and support. It is firmly positioned on the wall surface through bolts, ensuring the overall stability of the sound insulation board. The shock-absorbing pad frame 8 arranged between the mounting frame 1 and the wall surface can effectively absorb and buffer the vibration energy generated during the propagation of sound, thereby reducing the transmission of sound through the contact between the frame and the wall surface, and further improving the sound insulation effect.

[0042] Inside mounting keel frame and outside mounting keel frame

[0043] The inside mounting keel frame 2 and the outside mounting keel frame 3 are installed inside the mounting frame 1. They are made of pine wood that has been subjected to corrosion-resistant treatment. This treatment not only enhances the corrosion resistance of the wood, making it long-lasting in indoor environments without being prone to rot, but also maintains a certain strength and toughness of the pine wood itself. The two layers of keel frames form an inner and outer structure, providing a stable clamping and fixing frame for the center filler layer 4. This double-layer design can further enhance the overall structural strength compared to traditional single-layer designs. At the same time, the design of the center filler layer 4 can absorb the vibration between the inside mounting keel frame 2 and the outside mounting keel frame 3, resulting in better sound insulation effect compared to traditional single-layer keel frame designs.

[0044] Center filler layer

[0045] The center filling layer 4 is located at the center of the mounting frame 1, and is clamped between the inner mounting keel frame 2 and the outer mounting keel frame 3. The center filling layer 4 is made of sound-absorbing cotton material, which has excellent sound-absorbing performance and can effectively absorb sound energy, thereby reducing the propagation and reflection of sound and greatly improving the sound insulation effect of the entire sound insulation board. At the same time, it can also absorb the vibration of the inner mounting keel frame 2 and the outer mounting keel frame 3.

[0046] Sound-absorbing board

[0047] The sound-absorbing board 5 is located on the front side of the mounting frame 1 and is an important component of the sound insulation board. The back side is provided with a matrix-shaped positioning protrusion 52, which perfectly matches the grid-shaped space of the outer mounting keel frame 3. Through corresponding clamping, the sound-absorbing board 5 is accurately positioned and firmly installed on the keel. This design not only ensures the stability of the sound-absorbing board 5, but also enables the sound-absorbing board 5 to better play its sound-absorbing role. The outer surface of the sound-absorbing board 5 is provided with a plurality of "feng" shaped butt joint slots 51, which provide a convenient connection interface for the installation of the facing layer 6. At the same time, the sound-absorbing board 5 is positioned on the outer mounting keel frame 3 by a plurality of screws, and the plurality of screws penetrate the outer mounting keel frame 3 and the center filling layer 4 and are positioned on the inner mounting keel frame 2, further improving the overall structure and connection strength.

[0048] Facing layer

[0049] The facing layer 6 is clamped on the outer surface of the sound-absorbing board 5, providing an attractive appearance for the sound insulation board. It is composed of a plurality of parallel independent decorative plates 61. Each independent decorative plate 61 is provided with a "feng" shaped butt joint protrusion 611 on the back. These butt joint protrusions 611 accurately correspond to the butt joint slots 51 on the outer surface of the sound-absorbing board 5, achieving stable clamping of the facing layer 6 on the sound-absorbing board 5. In addition, in order to further enhance the installation firmness of the facing layer 6, the independent decorative plate 61 and the surface of the sound-absorbing board 5 are connected by adhesive, which not only ensures that the facing layer 6 will not easily fall off during use, but also makes the appearance of the entire sound insulation board more smooth and beautiful.

[0050] Filling block

[0051] The grid-shaped space inside the inner mounting keel frame 2 is filled with filling blocks 7, which are also made of sound-absorbing cotton material. These filling blocks 7 cooperate with the center filling layer 4 to play a sound-absorbing role, further improving the sound insulation performance of the entire sound insulation board. The filling blocks 7 made of sound-absorbing cotton material can effectively absorb sound energy, reduce sound reflection and propagation, and enable the sound insulation board to perform excellent sound insulation effect in various sound environments.

[0052] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
