Technical Field

[0001] The utility model belongs to the technical field of production of decorative composite panels, and specifically relates to an aluminum alloy honeycomb panel, in particular to a high-efficiency sound-insulating composite aluminum alloy honeycomb panel. Background Art

[0002] Aluminum alloy honeycomb panel is a kind of decorative panel, which is widely used in indoor and outdoor decoration projects. Its basic structure is to set a honeycomb core as a filling layer in an aluminum alloy shell. This structure makes the whole decorative panel have sufficient thickness and only requires part of the aluminum alloy material, thus achieving the purpose of beauty, strength and cost reduction.

[0003] In indoor wall decoration, some specific application occasions such as hotels, KTV rooms, etc. have high requirements for sound insulation. The sound insulation function of traditional aluminum alloy honeycomb panels is basically all achieved by honeycomb cores, which is difficult to meet the demand for efficient sound insulation. In practical applications, the above-mentioned traditional aluminum alloy honeycomb panels are installed on indoor walls using keels to form a certain interlayer space between the aluminum alloy shell and the wall. This space can improve the sound insulation effect to a certain extent, but the installation is more troublesome, and the installation stability is not as reliable as directly installing the aluminum alloy shell in contact with the wall. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency sound-insulating composite aluminum alloy honeycomb panel that is easy to install stably in order to solve the above problems.

The gel in the particle layer is generally provided on the surface, the purpose of which is to fix and encapsulate the particles and the honeycomb core in the shell cavity so that they are in a stable state, thereby achieving better soundproofing and noise reduction functions.

[0007] Preferably, in order to meet different requirements for panel surface forms, the particle layer completely covers the corresponding surface of the open end of the honeycomb core close to the inner cavity of the outer shell, and the surface of the particle layer serves as the surface of the high-efficiency sound insulation composite aluminum alloy honeycomb panel; or, an aluminum alloy cover plate is installed at the open end of the inner cavity of the outer shell, and the aluminum alloy cover plate is a porous plate provided with a plurality of through holes, and the surface of the aluminum alloy cover plate serves as the surface of the high-efficiency sound insulation composite aluminum alloy honeycomb panel.

[0008] Preferably, in order to achieve a decorative lighting effect, a decorative lighting lamp is installed in the interlayer space of the outer shell, the aluminum alloy partition is a porous plate with a plurality of through holes, and the honeycomb core and the particle layer are provided with a plurality of light-guiding optical fibers for directing the light of the decorative lighting lamp to the surface of the high-efficiency sound-insulating composite aluminum alloy honeycomb panel.

[0009] Preferably, in order to facilitate adjustment of light color and brightness and save energy, the decorative lighting is an LED light strip.

[0010] Preferably, in order to achieve better sound insulation effect, the particle layer is a quartz sand layer.

[0011] The beneficial effects of the utility model are:

[0012] The utility model forms a shell sandwich space by arranging an aluminum alloy partition in the inner cavity of the shell, and fills a particle layer in the honeycomb core. On the one hand, the sound wave is reflected multiple times by the honeycomb core to achieve the function of sound insulation and noise reduction. On the other hand, the sound wave is transmitted between the particles, and its transmission path is significantly increased. A large part of the sound wave is converted into heat energy and consumed, thereby achieving better sound insulation and noise reduction effects. Finally, the sound wave reaching the shell sandwich space is further dissipated by viscosity in the space, and finally a better sound insulation and noise reduction effect is achieved, meeting the demand for efficient sound insulation. In addition, the utility model is easy to install and can be directly mounted on the wall. The installation stability is high and it is more stable and reliable. The utility model can also achieve efficient sound insulation for sound waves of different frequency bands by changing the particle size and the height of the shell sandwich space. It has wide adaptability and is easy to popularize and apply. BRIEF DESCRIPTION OF THE DRAWINGS
