A Study on Risk Analysis by Type of Ceiling Material Based on Fire Theory
초록
In general, when a building fire occurs, the heat flow rises by buoyancy, which affects the temperature rise of the ceiling. In addition, when the ceiling ignites, the fire spreads rapidly due to horizontal spread and radiant heat. According to the fire investigation, most of the large fires have a common characteristic that the fire spreads to the ceiling and causes many casualties. Therefore, it is considered that it is necessary to review the fire risk of ceiling materials used in buildings to prevent the spread of fire to the ceiling. Therefore, in this study, combustion characteristics such as the amount of heat released and ignition time of each SMC, DMC, and gypsum board were checked using a Cone Calorimeter, and the ignition temperature was calculated by substituting them into the fire theory. As a result, the ignition temperature of SMC was 449K, that of DMC was 1492K, and that of gypsum board was 677K.
