Description

Technical Field

[0001] This utility model relates to the field of firewall technology, specifically a double-sided sound-absorbing firewall. Background Technology

[0002] In modern industrial and mining enterprises, there are often two sides of a partition wall where the noise is relatively severe. Therefore, the requirements for noise control are relatively high, which means that both sides of the wall need to be treated for sound absorption and sound insulation. Therefore, if the sound absorption and sound insulation performance of the wall needs to be enhanced, the thickness of the wall can only be increased, which will reduce the production space. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application provides a double-sided sound-absorbing fireproof wall panel, including an installation layer. The installation layer has an installation cavity inside, and a fireproof layer and a sound insulation layer are disposed inside the installation cavity. Sound-absorbing layers are disposed on both outer sides of the installation layer.

[0004] Furthermore, both the fireproof layer and the sound insulation layer are made of vertical fiber rock wool board. The vertical fiber rock wool board can not only improve the sound insulation and fireproof effect at the same time, but its own structure can also increase the strength of the wall.

[0005] Furthermore, the fireproof layer is made of hydrophobic fiberglass cloth, the sound insulation layer is made of sound-absorbing cotton, the installation cavity is wrapped with hydrophobic fiberglass cloth, and the interior is filled with sound-absorbing cotton.

[0006] Furthermore, the sound-absorbing layer is a porous foam ceramic board.

[0007] Furthermore, the mounting layer is a profile with tongue and groove joints at its edges. Furthermore, a decorative layer is also provided on the outer side of the sound-absorbing layer, and the decorative layer is made of microporous aluminum plate.

[0008] The advantages of this application are: the provided double-sided sound-absorbing fire wall panel not only improves the sound absorption effect, but also does not take up much space. One wall can meet the sound absorption needs of two rooms at the same time, which saves on investment costs and material and labor inputs. Attached Figure Description

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0018] See Figure 1 This embodiment provides a double-sided sound-absorbing fire wall panel, including an installation layer 10. The installation layer 10 is made of profiles, such as aluminum profiles, with tongue and groove joints at the edges for installation between fire wall panels. The installation layer 10 has an installation cavity inside, in which a fireproof layer and a sound insulation layer are provided. Sound-absorbing layers are provided on the two outer sides of the installation layer 10 to achieve double-sided sound insulation of the entire wall panel.

[0019] In this embodiment, the fireproof layer is made of water-repellent glass fiber cloth (not shown in the figure) to wrap the installation cavity inside the profile. The sound insulation layer is the space inside after wrapping, and is filled with sound-absorbing cotton 11. The sound-absorbing layer outside the profile is made of porous foam ceramic board 12. The sound-absorbing surfaces of the porous foam ceramic board 12 are arranged outward and fixed to both sides of the profile with glue.

[0020] When sound passes through the micropores on the porous foam ceramic board, some of the sound energy is consumed. After entering the installation cavity, it is absorbed by the sound-absorbing cotton, refracted and reflected, and then passes through the sound-absorbing holes of the ceramic board. Some of it returns to the sound-absorbing cotton to repeat the process, thus making the sound absorption effect more obvious. Example

[0021] See Figure 2 This embodiment provides a double-sided sound-absorbing fire wall panel, including an installation layer 10. The installation layer 10 is made of profiles, such as aluminum profiles or other profiles, with tongue and groove joints at the edges for installation between fire wall panels. The installation layer 10 has an installation cavity inside, and a fireproof layer and a sound insulation layer are provided inside the installation cavity. Sound-absorbing layers are provided on the two outer sides of the installation layer to achieve double-sided sound insulation of the entire wall panel.

[0022] In this embodiment, the fireproof layer and the sound insulation layer are an integrated structure, both using vertical fiber rock wool board 13. The vertical fiber rock wool board 13 has a good sound insulation effect, and at the same time, the vertical fiber rock wool board itself has a certain strength, which can further increase the overall strength of the entire wall panel.

[0023] Specifically, the sound-absorbing layer also uses porous foam ceramic board 12. The sound-absorbing surfaces of the porous foam ceramic board 12 are arranged outward and fixed to both sides of the profile with glue. A decorative layer is also provided on the outside of the porous foam ceramic board 12. This decorative layer uses microporous aluminum board 14. The microporous aluminum board 14 has both decorative and sound-absorbing functions.

[0024] The sound passes through the microporous aluminum plate 14 once, and when it turns into the micropores in the porous foam ceramic plate 12, some of the sound energy is consumed. When it enters the vertical fiber rock wool board 13 inside the wall panel, some of the energy is consumed again. It is then reflected through the ceramic plate and returns to the microporous aluminum plate to repeat the process. This makes the sound absorption and insulation effect more obvious.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
