[0036] Optionally, the material of the fireproof core material 24 is aluminum oxide fiber; and the material of the first fireproof panel 23 and the second fireproof panel 25 is glass magnesium plate.

[0037] Alumina fiber has fireproof performance, mainly because of its high temperature resistance, fire resistance and excellent physical and chemical stability. Alumina fiber is a polycrystalline inorganic fiber with alumina (Al2O3) as the main component, usually containing about 5% of silicon dioxide (SiO2) for stabilizing the crystal phase and inhibiting the growth of crystal grains at high temperature. This material is prepared by high-tech "sol-gel" method, through soluble aluminum, silicon salt to form a colloidal solution with certain viscosity, then through high-speed centrifugal spinning into fiber embryo, and then through dehydration, drying and medium-high temperature heat treatment crystallization process to become polycrystalline fiber. The alumina fiber formed in this process, the main crystal phase is mainly corundum phase and a small amount of mullite phase, has excellent heat resistance and stability, the service temperature can reach 1450℃-1600℃, the melting point is as high as 1840℃. The fireproof performance of alumina fiber is mainly due to its high heat resistance and low thermal conductivity. Because of the dense crystal structure of alumina fiber, it can still maintain strength without deformation at high temperature. Its thermal conductivity is only 1 / 6 of that of ordinary refractory bricks, and its bulk density is only 1 / 25 of that of ordinary refractory bricks, with energy saving rate of 15-45%. This means that in a high temperature environment, alumina fiber can effectively isolate heat conduction and greatly slow down the spread of fire. In addition to low thermal conductivity, alumina fiber also has good chemical stability and corrosion resistance. It can be used in acidic environment, oxidizing atmosphere, reducing atmosphere and vacuum conditions, and also has certain corrosion resistance to alkaline environment. These properties make alumina fiber not only an effective fireproof material under normal conditions, but also maintain its performance in harsh environments, such as in chemical or high-temperature metallurgical environments, it can still provide reliable fire protection. In addition, the mechanical properties of alumina fiber also support its fireproof performance. Because of its small fiber structure and high tensile strength, it can still maintain physical strength at high temperature and will not be quickly damaged or disintegrated. This feature enables it to provide long-term protection as a thermal barrier in emergency situations such as fires, thereby gaining valuable time for evacuation and fire fighting.

[0038] Compared with traditional fireproof filling core materials such as magnesium oxide perlite board, flame-retardant perlite board, foam cement fireproof board and non-combustible materials such as fire-resistant gypsum board, alumina fiber has the advantages of easy preparation and low cost, so the utility model has great market advantage. The glass magnesium board is a board made of active high-purity magnesium oxide (MgO), high-quality magnesium chloride (MgCl2), alkali-resistant glass fiber cloth, plant fiber and non-combustible light perlite. It not only has excellent fire resistance and can withstand high temperature for a long time and maintain structural stability, but also performs well in environmental protection, does not contain harmful substances and does not pollute the environment, and does not release toxic gases during use.

[0039] In order to facilitate processing and ensure structural strength, the partition plate 231 and the first fireproof panel 23 are integrally formed in this embodiment.

[0040] Optionally, surfaces of the main frame structure 2, the auxiliary frame structure 22, the first fireproof panel 23 and the second fireproof panel 25 are provided with a fire-retardant coating layer (not shown in the figure).

[0041] The fire-retardant coating layer can be a ceramic protective coating, a polymer-based fireproof coating, a nano fireproof coating, a cement-based protective coating, etc.

[0042] In order to ensure the structural strength and improve the fire resistance, the main frame structure 2, the horizontal rod 21 and the auxiliary frame structure 22 are all made of steel.

[0043] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields, etc. made by using the content of the present application specification and drawings under the utility model concept of the present application are included in the patent protection scope of the present application.
