Abstract
Aged fire doors may develop leakage cracks owing to damage from long-term use, leading to issues such as declines in the functionality of pressurization systems. This study analyzes the trends of leakage cracks in aged fire doors based on existing research and field surveys and derives the differential pressure and leakage amounts corresponding to each leakage crack via experiments conducted in a full-scale ancillary room. The results indicate that an increase in the number of leakage cracks tends to result in a decrease in the design differential pressure, which thereby prevents the fire door from performing its intended functions. Moreover, the results confirm that an increase in the number of leakage cracks also affects the leakage amounts.
Key Words: Aged Fire Door, Leakage Crack, Differential Pressure, Leakage Amount, Experiment
요지
노후화된 방화문은 장기간 사용으로 인해 손상이 발생하여 누설틈새가 생길 수 있으며, 이로 인해 급기압 설비의 기능 저하 등의 문제가 발생할 수 있다. 본 연구에서는 기존 연구 및 현장 조사를 기반으로 노후화 방화문의 누설틈새 경향을 분석하고, 실물 크기의 부속실을 가정한 실험을 통해 각 누설틈새에 따른 차압 및 누설량을 도출하였다. 연구 결과, 누설틈새의 증가는 설계 차압의 저하를 초래하여 방화문의 본래 역할을 수행하지 못하게 되는 경향을 확인하였다. 또한, 이는 누설량에도 영향을 미치는 것을 확인하였다.
핵심용어: 노후화 방화문, 누설틈새, 차압, 누설량, 실험
