Abstract

This study dealt with the problem of increasing the importance of improving seismic performance in fire prevention systems as the frequency and intensity of earthquakes increase. In general, conventional welding sprinkler systems are vulnerable to structural damage when an earthquake occurs, which can worsen the risk of fire. Therefore, this study proposed the development of a non-convex modular system designed to improve the structural safety of fire prevention equipment in the event of an earthquake. As a result, the non-welding modular system showed excellent efficiency and stability under seismic conditions as the welding area ratio (99.1%) was significantly higher than that of the existing system (95.4%). In addition, the uniformity of welding thickness of the non-welding system contributed to structural integrity and reduced the risk of damage during external impact. Overall, this study demonstrated the potential of non-convex modular systems to improve the safety and effectiveness of fire protection measures and to conform to globally enhanced fire safety regulations.

본 연구는 지진의 빈도와 강도가 증가함에 따라 방화 시스템에서 내진 성능 향상의 중요성이 커지고 있는 문제를 다루었다. 일반적으로 기존의 용접 스프링클러 시스템은 지진 발생 시 구조적 손상에 취약하여 화재 관련 위험을 악화시킬 수 있다. 이에 본 연구는 지진 발생 시 방화 장비의 구조적 안전성을 개선하도록 설계된 비용접 모듈식 시스템의 개발을 제안하였다. 결과적으로 비용접 모듈식 시스템은 기존 시스템(95.4%)에 비해 용접 면적 비율(99.1%)이 상당히 높아 내진 조건에서 뛰어난 효율성과 안정성을 보였다. 또한, 비용접 시스템의 용접 두께 균일성은 구조적 무결성에 기여하여 외부 충격 시 파손 위험을 줄여 주었다. 전반적으로 본 연구를 통해 비용접 모듈식 시스템이 화재 보호 조치의 안전성과 효과를 향상시키고 전 세계적으로 강화된 화재 안전 규정에 부합하는 잠재력을 보여주었다.
