As high-rise buildings bring vitality and vitality to our cities, the fire prevention work has become increasingly severe. Through the analysis of fire accidents that have occurred in recent years, it has been shown that smoke is the main cause of casualties in building fires. The hazards of smoke to people during a fire are mainly manifested in two aspects: the fire smoke contains a large amount of toxic gas and the smoke is not conducive to the evacuation of people. Because the hazard of smoke to people is the main cause of casualties in fires, preventing the spread of smoke, removing high-temperature smoke in time, and ensuring the smooth evacuation of people are the main goals of the smoke prevention and exhaust design of high-rise buildings.

Fire resistance performance requirements of smoke prevention and exhaust pipes

According to "Technical Standards for Building Smoke and Smoke Exhaust Systems" GB51251-2017 Article 3.3.8, 4.4.8, 4.5.7 for the setting of smoke control systems and fire resistance limits, the performance of smoke control pipes must meet the following requirements:

According to the "Technical Standards for Smoke Control and Exhaust Systems in Buildings" (GB 51251-2017) for the technical requirements for smoke control systems, pipe insulation materials are professionally designed for application characteristics. The special heat-insulating glass wool for the smoke control system is wrapped on the outside of the metal smoke control pipe, which can isolate the heat of the fire smoke and prevent it from passing through the pipe wall. It can effectively help the smoke control pipe to achieve the required fire resistance and heat insulation effect. In the event of a fire, smoke and heat are removed to ensure personnel evacuation and fire rescue.imgimg

* The overall fire resistance test of ventilation ducts is a large-scale fire-resistant structure experiment. At present, the only authoritative testing institutions are the National Fireproof Building Material Quality Supervision and Inspection Center in Dujiangyan, Sichuan Province and the National Fixed Fire Extinguishing System and Fire-Resistant Structure Quality Supervision and Inspection Center in Tianjin.
