[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] like Figure 1-3 As shown, this utility model provides an aluminum alloy wall, comprising: a plurality of high-performance aluminum alloy profile columns 1, a flame-retardant filling core 2, and a magnesium oxide board 3; The high-performance aluminum alloy profile column 1 has a cavity 4 inside. The horizontal cross-section of the cavity 4 is rectangular. Adjacent high-performance aluminum alloy profile columns 1 are connected by tongue and groove joints, and fireproof sealing strips are installed at the joints. The fireproof sealing strips are made of intumescent fireproof sealant, which has good sealing performance at room temperature and can prevent air and moisture penetration. When a fire occurs, the sealing strips will expand rapidly, fill the joint gaps, and prevent flames and smoke from spreading through the gaps, further improving the overall fire resistance of the wall.

[0021] The tongue-and-groove connection structure is as follows: a protruding mounting strip 5 is provided on the left side of the high-performance aluminum alloy profile column 1, and a recessed mounting slot 6 is provided on the right side of the high-performance aluminum alloy profile column 1. The mounting slot 6 and the mounting strip 5 are matched in shape.

[0022] The high-performance aluminum alloy profile column 1 has connection holes 7 on its front and rear sides, corresponding to the mounting slots 6 and mounting strips 5, respectively. The connection holes 7 are equipped with connecting bolts 8. After the mounting strips 5 are inserted into the mounting slots 6, the two adjacent high-performance aluminum alloy profile columns 1 are connected by screwing the connecting bolts 8 into the connection holes 7.

[0023] The connecting holes 7 on the high-performance aluminum alloy profile column 1 are matched with the connecting bolts 8. After the connecting bolts 8 are fully screwed in, the surface of the high-performance aluminum alloy profile column 1 remains flat, which facilitates the installation of the magnesium oxide board 3.

[0024] The connecting bolt 8 is a stainless steel bolt. The stainless steel bolt is equipped with a reinforcing washer at the connection position with the high-performance aluminum alloy profile column 1 to enhance the load-bearing capacity of the connection node and prevent loosening under long-term use or external force.

[0025] The high-performance aluminum alloy profile column 1 has raised mesh-like reinforcing ribs 9 on the profile surface corresponding to the sides of the chamber 4. The high-performance aluminum alloy profile column 1 internally contains several transverse reinforcing ribs 10 and several longitudinal reinforcing ribs 11. The two ends of the transverse reinforcing ribs 10 are supported between the left and right side walls of the high-performance aluminum alloy profile column 1, respectively, while the two ends of the longitudinal reinforcing ribs 11 are supported between the front and rear side walls of the high-performance aluminum alloy profile column 1, respectively. Through the mesh-like reinforcing ribs 9, the transverse reinforcing ribs 10, and the longitudinal reinforcing ribs 11, the frame's resistance to deformation and overall strength are improved.

[0026] The high-performance aluminum alloy profile column 1 is made of specially treated aluminum alloy material. By optimizing the proportion of elements such as copper, magnesium and silicon in the alloy composition and using an age hardening process, its yield strength reaches more than 320MPa. For example, 6A13 aluminum alloy or 6H13 aluminum alloy is selected to ensure that the frame can bear the weight of the wall itself and external loads.

[0027] The flame-retardant filler core 2 is installed inside the cavity 4 of the high-performance aluminum alloy profile column 1. The thickness of the flame-retardant filler core 2 matches the internal space of the cavity, ensuring a tight bond with the frame after filling. The flame-retardant filler core 2 can be made of flame-retardant rigid polyurethane foam with a thermal conductivity ≤0.025W / (m²). K) possesses excellent thermal insulation properties, effectively reducing heat transfer between indoors and outdoors and improving the building's energy efficiency. Simultaneously, flame-retardant polyurethane is not easily ignited when exposed to flames and produces less smoke during combustion, reducing fire hazards and enhancing the fire resistance of walls when combined with other structural elements.

[0028] After multiple high-performance aluminum alloy profile columns 1 are connected, magnesium oxide boards 3 are respectively attached to the front and rear sides of the high-performance aluminum alloy profile columns 1. The magnesium oxide boards 3 are bonded and fixed to the high-performance aluminum alloy profile columns using high-temperature resistant adhesive. The magnesium oxide boards 3 are made of a ternary system of magnesium oxide, magnesium chloride, and water as the base material, with the addition of appropriate fillers and modifiers, and have the characteristics of high strength, fire resistance, moisture resistance, and sound insulation. Its fire resistance limit can reach more than 3 hours, which can effectively block the spread of flames and protect the internal structure from high-temperature damage in the event of a fire. The 18mm thickness design ensures the structural strength of the magnesium oxide boards 3, and can be matched with the overall wall thickness of 116mm, realizing the thinness of the wall.

[0029] The aluminum alloy wall of this utility model is suitable for various types of buildings with specific requirements for wall strength, fire resistance, heat insulation performance and thickness, such as high-rise buildings, industrial plants, commercial complexes, etc.

[0030] As one embodiment of this utility model, a wall is formed by combining a high-performance aluminum alloy profile column, a polyurethane filling core, and a magnesium oxide board 3. The total wall thickness is set to 116mm, the magnesium oxide board 3 thickness is 18mm, and the thickness of the high-performance aluminum alloy profile column 1 and the polyurethane filling core is 80mm. The various parts work together to form a structurally stable and high-performance wall as a whole, achieving comprehensive performance of high strength, high fire resistance, and good thermal insulation, providing a better wall solution for buildings.

[0031] The advantages of this utility model are: High Strength and Stability: The design of the high-strength, high-performance aluminum alloy profile column 1 and the installation of reinforcing ribs give the wall excellent structural strength and resistance to deformation, enabling it to withstand large vertical loads and horizontal thrusts. This makes it suitable for high-rise buildings and other applications requiring high wall strength. Testing shows that the high-performance aluminum alloy wall of this invention has a wind pressure resistance of over 5 kPa and an impact resistance of 10 kJ / m², meeting the needs of various building types. Excellent fire resistance: The 18mm thick magnesium oxide board on both sides has good fire resistance properties. Combined with the flame-retardant polyurethane filling layer and fireproof sealing strip, the fire resistance limit of the wall reaches more than 1.5 hours, which can effectively delay the spread of fire and buy time for personnel evacuation and fire rescue. Excellent thermal insulation performance: The low thermal conductivity of the flame-retardant rigid polyurethane filling layer significantly reduces the heat transfer coefficient of the wall, greatly improving its thermal insulation performance. In winter, it reduces indoor heat loss, and in summer, it prevents outdoor heat from entering, reducing building air conditioning energy consumption and meeting building energy efficiency standards. Excellent sound insulation performance: High-performance aluminum alloy partition wall panels have excellent sound insulation performance, capable of reducing sound volume by 40-50 decibels. They are excellent building materials with both sound insulation and sound absorption effects, effectively reducing noise pollution and creating a quiet and comfortable living environment for users.

[0032] Lightweight design: With a total thickness of only 116mm, the design significantly reduces the building space occupied by walls compared to traditional heavy walls, thus improving the utilization rate of the building's usable area. At the same time, the lightweight material composition (overall weight ≤80kg / m²) reduces the building's self-weight, which helps to reduce the load on the building foundation and lower construction costs. Durability and Environmental Friendliness: The high-performance aluminum alloy profile column 1 has excellent corrosion resistance and oxidation resistance, while the magnesium oxide board 3 is moisture-proof and insect-proof. The polyurethane filling layer has good chemical stability, giving the wall a long service life overall. Furthermore, all materials used are environmentally friendly, releasing no harmful gases and meeting the requirements of green building.
