1, coating a fireproof coating Coating fire retardant coating is a widely used fire protection method for metal structures at present. The method mainly comprises the following steps: spraying or brushing a fireproof coating on the outer surface of a metal structure to form a fireproof film. The fire retardant coating has a certain chemical reaction ability, which can diffuse heat at high temperature, thus slowing down the temperature rise of the metal structure and protecting the steel structure from ablation. In general, the thickness of fire retardant coating is directly proportional to the fire rating, so it is necessary to choose the corresponding fire retardant coating according to different building requirements and regulations. Second, the use of fire isolation Fire isolation is another commonly used fire prevention method for metal structures. In this method, an isolation layer is set inside the metal structure to form an isolation zone to block the fire and prevent the fire from spreading. Inorganic materials, such as high-temperature resistant lightweight brick, fiberboard and ceramic fiber, are usually used as fireproof insulation materials. At present, fire isolation is widely used in high-rise buildings. However, it should be noted that the fire isolation needs to be kept intact, otherwise it will lose its effect. Third, install a fire curtain Installing a fire curtain is a passive fire prevention measure. At the opening of the metal structure, installing a fire curtain can form a sealed fire-proof space in case of fire, and delay the spread of fire. Fireproof curtain is usually made of fireproof materials, which has high transparency and can have both fire prevention and observation functions at the same time. At the same time, the fire curtain also needs to have fire resistance within the specified time, which can resist the attack of high temperature.
