A Legal Alternative for Effective Application of Pressurized Smoke Control System to Provide ′Smoke-free′ Access for Escape Shafts Used in High-Rise Building

요약

화재시 특별피난계단의 부속실의 연기침입을 방지하기 위해 적용하고 있는 급기가압방연시스템의 효능에 대한 논란이 증가하고 있는 바, 국내 고층 건축물의 특별피난계단에 설치운용중인 급기가압시스템의 설계시 핵심요소인 가압공간의 누설틈새, 계단실과 부속실 또는 부속실과 거실공간사이의 출입문을 통한 방연풍속과 출입문의 자동폐쇄를 보장하는 도어 개폐장치등에 대한 문제점을 조사연구하여 실질적인 효과를 보장할 수 있는 기준을 설정하고, 안전성확보를 보장하면서 경제성을 고려한 설계안을 세부적인 사례를 들어 구체적으로 제시하였다.

Abstract

There have been the current controversy over effectiveness of the pressurized smoke control systems, which are installed within escape shaft to provide 'smoke-free' access for escaping peoples. Therefore, many effective measures were given in this paper by means of the production of a design guide for various types of escape routes used in domestic buildings. The solutions were established on basis of both an investigating current door closing device application in existing facilities and global standardization for pressurized smoke control system, especially in British Standard. Finally, the design guidance for open door air velocity with introduction to three door protection clauses was presented on the basis of consideration of the safety and economical factor,
