Description

A sound-absorbing panel with a sound-absorbing cavity Technical Field

[0001] This utility model belongs to the field of building materials technology, and specifically relates to a sound-absorbing panel with a sound-absorbing cavity. Background Technology

[0002] Sound absorption treatment is generally applied to the joint between the roof and the curtain wall. Typically, sound-absorbing panels are installed on the roof surface near the curtain wall to form a continuous, closed sound-absorbing barrier on the roof surface, preventing external sound waves from penetrating into the building. In addition, it also provides additional structural support to enhance the overall stability of this location.

[0003] Sound-absorbing panels are placed at the joints of the roof and curtain wall. The surface of the sound-absorbing panels has tiny gaps and interconnected channels, which adopts the principle of porous sound absorption. However, the sound absorption effect of this method is limited and is easily affected by the ambient humidity. When the humidity is high, moisture can easily enter the pores of the sound-absorbing panels, occupy part of the pore space, and obstruct the air flow in the pores, thereby reducing the sound absorption effect. Although the sound-absorbing panels have certain sound absorption performance, they cannot be waterproofed, which is a drawback.

[0004] The existing sound-absorbing panels installed at the joints of roofs and curtain walls have the problem of not having waterproof and anti-backflow design. To address this, this application proposes a sound-absorbing panel with a sound-absorbing cavity. Summary of the Invention

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 3. This utility model provides a technical solution: a sound-absorbing panel with a sound-absorbing cavity, comprising a sound-absorbing substrate 1 for use at roof and curtain wall joints, including a parallel first substrate 11 and a second substrate 13, a side plate 12 installed between the sides of the first substrate 11 and the second substrate 13, and a support plate 14 perpendicular to the first substrate 11 and the second substrate 13.

The sound-absorbing substrate 1 serves as a sound-absorbing material, and the sound-absorbing substrate 1 contains the sound-absorbing cavity 15. When sound waves from the outside enter the sound-absorbing cavity 15 inside the sound-absorbing substrate 1, the incident sound waves undergo multiple reflections and refractions within the sound-absorbing substrate 1, generating interference between sound waves along different paths, thus weakening the sound energy and achieving the purpose of sound absorption, playing the role of sound absorption and noise reduction; and a soundproofing plate fixedly connected to the second substrate 13. Waterproof board 2 has waterproof protrusions 21 on its surface. The waterproof board 2 is firmly bonded to the sound-absorbing substrate 1 with adhesive. The waterproof protrusions 21 are embedded inside the sealing board 3. The waterproof board 2 and the sealing board 3 are tightly bonded, and the waterproof board 2 and the waterproof protrusions 21 serve a waterproof function. The sealing board 3 is attached to the waterproof board 2. The waterproof board 2 and the sealing board 3 are attached together. Under the synergistic effect of the waterproof board 2 and the sealing board 3, they serve a sealing and waterproof function. A waterproof pipe 4 is welded to one end of the sealing board 3. There is a height difference between the waterproof pipe 4 and the waterproof board 2, which serves to prevent backflow. A reinforcing plate 5 is fixed to the outside of the waterproof pipe 4 with screws. The reinforcing plate 5 is in contact with the curtain wall material and is reinforced by applying a fixed mortar layer to keep the waterproof board 2 and the waterproof pipe 4 stable. The surface of the sealing board 3 has protective protrusions 31, which serve to protect the surface of the sealing board 3.

[0025] In this embodiment, the surface of the second substrate 13 is provided with a sound-absorbing hole 131 that communicates with the sound-absorbing cavity 15, which facilitates the entry of external sound waves into the sound-absorbing substrate 1.

The sealing plate 3 has a groove that mates with the waterproof protrusion 21. The groove and the groove are connected. The waterproof protrusion 21 is a right trapezoidal three-dimensional structure, and the inclined surface of the waterproof protrusion 21 is stepped. The waterproof protrusion 21 has a large contact area with the sealing plate 3, and the waterproof protrusion 21 is tightly connected with the sealing plate 3, thus achieving the effect of sealing and waterproofing.

[0028] In this embodiment, the protective protrusion 31 on the surface of the sealing plate 3 facing away from the waterproof plate 2 is wavy, and the wavy protective protrusion 31 protects the surface of the sealing plate 3.

[0029] In this embodiment, the waterproof pipe 4 is a hollow tube with a frame-shaped cross-section. The reinforcing plate 5 has a "Z"-shaped structure, with one end of the reinforcing plate 5 attached to the outer surface of the waterproof pipe 4.

There is a height difference between the waterproof pipe 4 and the waterproof plate 2, which helps to prevent backflow.

[0030] Working principle and usage process of this utility model:

[0031] When installing sound-absorbing panels at the joints of the roof and curtain wall, the sound-absorbing substrate 1 is fixed to the roof with bolts;

[0032] The sound-absorbing substrate 1 serves as a sound-absorbing material. The sound-absorbing substrate 1 contains a sound-absorbing cavity 15. When an external sound wave enters the sound-absorbing cavity 15 inside the sound-absorbing substrate 1, the incident sound wave undergoes multiple reflections and refractions within the sound-absorbing substrate 1, generating sound waves from different paths that interfere with each other, thereby reducing the sound energy and achieving the purpose of sound absorption, thus playing the role of sound absorption and noise reduction.

Under the synergistic effect of the waterproof board 2 and the sealing board 3, the sealing and water-repellent effects are achieved.
