In Japan, the thermal insulation material and the fireproof material are integrated, so the material requirements are particularly high. The thermal insulation performance of the thin-walled light steel structure is based on the principle of external thermal insulation. The air layer in the wall is connected with the roof to ensure the poor conductor of heat. The principle is similar to that of a thermos. Therefore, on the basis of not increasing the construction cost, the treatment of the building structure achieves excellent energy-saving and thermal insulation effects, and overcomes the disadvantages of moisture and insects caused by condensation, so this thermal insulation method has rapidly Replaces the internal insulation method. Thereby ensuring the characteristics of thin-walled light steel structure which is warm in winter and cool in summer. When the outdoor temperature is 0 degrees, the indoor can also maintain 17.2 degrees of natural air convection to adjust the indoor temperature to achieve warm in winter and cool in summer. 1. High material strength, light weight, high steel strength and high elastic modulus. Compared with concrete and wood, the ratio of its density to yield strength is relatively low, so under the same stress conditions, the steel structure has a small cross-section and light weight, which is convenient for transportation and installation, and is suitable for large spans, high heights, and heavy loads Structure. 2. The steel has good toughness, good plasticity, uniform material, high structural reliability, suitable for bearing impact and dynamic load, and has good seismic performance. The internal structure of steel is uniform, close to isotropic homogeneous body. The actual working performance of the steel structure is more in line with the calculation theory. Therefore, the reliability of the steel structure is high. 3. Steel structure manufacturing and installation with high degree of mechanization Steel structure components are easy to be manufactured in factories and assembled on site. The factory mechanized manufacturing of steel structural components has high precision, high production efficiency, fast assembly speed on site, and short construction period. Steel structure is a kind of structure with a high degree of industrialization. 4. The steel structure has good sealing performance. Because the welded structure can be completely sealed, it can be made into high-pressure containers, large oil pools, pressure pipes, etc. with good air-tightness and water-tightness. 5. The steel structure is heat-resistant and not refractory. When the temperature is below 150 °C, the properties of the steel change very little. Therefore, the steel structure is suitable for hot workshops, but when the surface of the structure is exposed to heat radiation of about 150 ° C, it should be protected by a heat insulation board. When the temperature is between 300°C and 400°C, the strength and elastic modulus of the steel decrease significantly. When the temperature is around 600°C, the strength of the steel tends to zero. In buildings with special fire protection requirements, the steel structure must be protected by refractory materials to improve the fire resistance rating. 6. The corrosion resistance of steel structure is poor, especially in the environment of damp and corrosive medium, it is easy to rust. Generally, the steel structure needs to be derusted, galvanized or painted, and it needs to be maintained regularly. For offshore platform structures in seawater, it is necessary to use“Zinc block anode protection”and other special measures to prevent corrosion. With the vigorous promotion of the government, building as soon as possible as soon as possible, light steel villas are now gradually entering the Chinese countryside, and they have begun to capture the market with their superior performance.
