In the actual implementation process, it is necessary to take into account fire safety and investment rationality. The fire protection design of high-rise buildings sometimes fails to meet the regulatory requirements, which leaves a safety hazard. Due to the high number of fire hazards in high-rise buildings, fires spread rapidly, fires are difficult to evacuate, and it is difficult to save. In view of its characteristics, in general, the following four aspects of fire protection design should be done. First, ensure that the main structure has sufficient fire resistance stability. At present, high-rise buildings at home and abroad rely on steel structures. Although its integrity and stability are good, the fire resistance is very poor. In general, the unprotected steel structure has a fire resistance limit of only 15 minutes. The tensile strength and load-bearing properties of the steel will drop sharply due to the increase of temperature. Usually, the bearing capacity will be lost at 450-650 degrees Celsius, deformation will occur, and the steel column and steel beam will be bent and cannot be used continuously. (Excellent fireproof clean board or flame retardant can be used as steel structure external wall panel, interior wall function Decorative Board fire protection) Second, strengthen self-rescue measures. When a fire occurs, the height of the fire department ladder can generally reach no more than 100 meters. If a high-rise building with a height of several hundred meters is fired, it is difficult to rely on external forces to rescue. High-rise buildings rely mainly on their own fire protection measures to ensure safety. At present, the self-rescue measures of high-rise buildings are mainly divided into active and passive categories. The active measures of rock wool insulation board refer to technologies that directly limit the occurrence and development of fire, such as fire detection and alarm technology, fire extinguishing technology such as water sprinkler, flue gas control technology, etc. Passive measures refer to improving or enhancing building components or materials to withstand fire damage. Capabilities of technology, such as techniques to improve the fire resistance of building components. These perfect self-rescue measures are more able to cope with sudden fires than a large number of firefighters.
