The fire compartments with fire-resistant construction are installed in the principal structural parts of a building in order to reduce damage in the event of a building fire. As a fire may spread through a crack in the fire compartment, the firestop with secured performance is used according to the procedure, methods, and standards specified in the detailed operation guideline. According to the current detailed operation guideline, vertical members (wall penetration) and horizontal members (floor penetration) are classified into different categories respective to each other for the classification of the firestop. Therefore, an accreditation applicant must apply for the performance test for each structure even if the wall and the floor have the same structure. Also, Grade T is used for the firestop that penetrates the fire compartment. However, in the case of foreign countries, the use of Grade F for the firestop is allowed even if it penetrates the fire compartment. The result of the precedent studies also showed that there was a significantly low possibility of fire to spread even if Grade F was applied for a metallic duct that penetrated the fire compartment. In this study, the improved scheme for the classification and performance standard of firestops was presented by analyzing the results of precedent studies regarding the firestop and domestic and overseas firestop qualification systems.

In this paper, the effect of change of sleeve type on fireproofing performance of through-penetration firestop system on metallic pipes was analyzed. As a result, if the material of the sleeve is high in thermal conductivity and thick, a large amount of heat is transferred to the top of the support structure.

최근 성능기준에 의한 평가규정이 시행된 건축물 내화충전구조에 대해 관련 제도운영체계와 국내외 성능평가방법 및 성능기준을 살펴본 후 현재 기준의 보완점과 향후 개선방안에 대해 고찰하였다. 내화충전구조는 방화구획의 기능을 완성시키는 중요한 부분으로서 연구개발 및 시장활성화가 필요하며, 현장 품질을 확보 유지할 수 있는 관리체계가 필요하다. 한편 내화성능 뿐만 아니라 구조거동에 대한 대응 및 내구성에 대한 기술기준의 보완 마련이 필요하다.
