Meanwhile cladding can also use perlite, asbestos, gypsum or asbestos cement, made of lightweight concrete panels, the use of adhesives, nails, bolted to the steel. Steel prevent rapid warming in the fire deformed slump, its measures are varied, the key is to take different approaches under different circumstances, such as the use of insulation, refractory steel barrier direct flame burning, reduce the speed of heat transfer delayed steel temperature, strength becomes weak time.

Once a high-rise building fire accident, the fire could not be extinguished in a short time, which requires us to architectural design, building materials to increase fire protection, in order to enhance its fire resistance, and to develop the necessary emergency inside the building programs to reduce casualties and property losses. Using fireproof coatings protect components, this method has good fireproof insulation, steel construction without geometric restrictions, etc. Is added in the steel outer cladding, cast molding can be applied by spraying. Here are several different fire protection of steel structures.Steel is a building material will not burn, it has a seismic, bending and other features. Water-filled hollow steel structure is most effective against fire protection measures.

First, the outer cladding. Fourth, the expansion of the material. Steel is set in the wall or ceiling refractory composition, or the components concealed in the space between the two walls, as long as a slight increase or no increase refractories that can achieve the purpose of fire protection. After cooling the heated water can be recycled, or by the introduction of cold water pipes to replace the heated water. But no matter what method adopted, the principle is the same.

This is one of the most economical method of fire. This method enables the steel to maintain a relatively low temperature in the fire, the water circulating in the steel structure, the absorbent material itself heated heat. In practice, the relative increase in both hot working die steel steel load capacity of the building, but also meet the needs of architectural design aesthetic style, but also to avoid the concrete and other building materials can not be bent, stretched defects, so the steel construction industry has been favored, single-layer, multi-layer, skyscrapers, factories, warehouses, waiting rooms, lounges and other uses of steel are common. Cast concrete cladding forming entities generally or reinforced with steel mesh to strengthen, to limit shrinkage cracks, and to ensure the strength of the housing., generally do not need to add auxiliary facilities, and light coating quality, as well as some beautiful decorative effect, belongs to the modern advanced fire technical measures. Spray can at the construction site on the steel surface to form a protective layer coated sand pump, sand pump can be lime or cement plaster mortar, perlite or asbestos may also be incorporated. For Steel Materials overcome deficiencies in the practical application of fire prevention, fire protection must be treated, and its purpose is to improve the fire resistance of steel to design specification limits.. Currently, high-rise steel buildings is increasing, especially in some high-rise buildings, the use of steel material more widely.

However, the steel as a building material and there are some unavoidable deficiencies in fire protection, its mechanical properties, such as porosity, temperature increases due to a sharp decline in the yield point, tensile strength and elastic modulus.Third, the shield. Second, filling water (water jacket)
