Traditional wall materials, such as solid brick walls or concrete walls, although they have certain sound insulation and thermal insulation properties, often rely on increasing the wall thickness or density to improve their performance. This not only occupies valuable building area, but also increases the building's load and material costs.

The aluminum honeycomb composite wall has an inner panel and an outer panel. A honeycomb core is provided between the outer panel and the inner panel. An insulation board is provided between the honeycomb core and the outer panel. A strong adhesive is provided between each layer of the aluminum honeycomb composite wall for connecting the components. The splicing ends of the outer panel are symmetrically provided with slots. The slots are used in conjunction with the embedded bow-shaped fastener. This aluminum honeycomb composite wall is used in prefabricated buildings. It is green and environmentally friendly, warm in winter and cool in summer, has a long service life, good fire resistance, strong sound insulation, is lightweight and quick to assemble and disassemble, and can be recycled and reused.

[0004] However, existing composite walls exhibit significant sound and thermal bridging during use, resulting in insufficient overall sound absorption, insulation, and heat insulation performance. Furthermore, their weak seismic buffering capacity and inconvenient component installation and maintenance reduce structural stability, durability, and construction efficiency. Utility Model Content

[0008] As a further embodiment of this utility model, the heat insulation board is made of rock wool, and a damping washer is slidably connected to the surface of the fixing screw. The damping washer is made of rubber. The damping washer effectively buffers and absorbs vibration energy.

[0009] As a further embodiment of this utility model, one end of the shock absorber is threadedly connected to a limit nut, and the shock absorber is sleeved inside the vertical plate.

It also realizes convenient installation, fixing and subsequent maintenance of internal components, improving construction efficiency. At the same time, the sound insulation layer is made of polyurethane foam, which is filled with a large number of interconnected micropores. It can effectively convert the vibration energy of sound waves into heat energy and dissipate it, thereby significantly weakening and absorbing sound waves passing through the wall. The protective layer is made of cement fiber, which has high strength, impact resistance, and flame retardant properties. As the outermost layer of the wall, it can effectively resist external impact, wear and erosion, greatly enhancing the durability and safety of the wall.

[0014] 2. This hollow sound-absorbing and heat-insulating composite wall, through the setting of the limiting component, allows the fixing screw to be easily screwed in or out of the threaded sleeve by rotating the handles on both sides during use. This enables the rapid installation, precise positioning, and reliable fixing of internal components such as hollow partitions relative to the base wall, greatly improving construction efficiency and providing great flexibility for later maintenance, repair, or functional changes. At the same time, the damping washers can not only effectively buffer and absorb vibration energy, but also seal the gaps between components to a certain extent, which helps to improve the sound insulation and airtightness of the wall.
