Abstract

Statistics on the occurrence of fires in residential facilities over the past 10 years, show that approximately 40% are fires in apartment buildings. To prevent the spread of fire and support evacuation in apartment housing, the fire resistance performance and performance design of fire doors are becoming more important. This study established a database using 395 quality inspection reports from 2016 to 2020, which passed the fire performance test, and derived the fire door performance-influencing factors through an analysis of the structure (12 elements) of the fire door. As a result, the effect of core material, adhesive, hinge type, blowing agent, etc. was confirmed in 287 pass cases. On the other hand, it was confirmed that the occurrence of flames and crevices in the 108 cases of failure were the major failure factors in the fire door fire resistance test. Fire doors are composed of composite materials to prevent failure of fire resistance performance, and efficient design and quality control are required through standardization of components.

최근 10년간 주거시설에서 발생한 화재 중 공동주택이 약 40%를 차지하고 있다. 공동주택에서 화재 확산 방지와 피난을 위해 방화문의 내화성능과 성능설계가 중요해지고 있다. 본 연구는 화재성능시험을 통과한 2016년부터 2020년까지 품질검사보고서 395건의 DB를 구축하고 방화문의 구조(12개 요소)를 분석을 통하여 방화문 성능영향인자를 도출하였다. 결과로서, 287건의 합격사례에서 내화충진재와 밀도, 접착제, 발포제의 영향을 확인하였다. 한편, 불합격 사례 108건에서 화염발생과 틈새발생이 방화문 내화시험에서 가장 큰 불합격 요소임을 확인하였다. 방화문은 내화성능 불합격을 방지하기 위하여 복합자재들로 구성이 되어 있으며, 구성 요소들의 위치 등 형태를 정형화하여 일률적인 품질관리가 필요하다. 본 연구의 DB 분석 결과를 바탕으로 공동주택의 대피공간문 및 공용부 방화문에 대하여도 추가적인 비교분석이 필요하다.
