Abstract

The purpose of this study is to assess the criteria on a floor hinge and door closer for the optimum design of the access door of a smoke control room. The door opening force due to differential pressure is 60.75 N, 40.5 N, 32.91 N and 12.66 N when the differential pressure is 60 Pa, 40 Pa, 32.5 Pa and 12.5 Pa, respectively. The door opening force of the floor hinge and door closer to which the criteria of KS F 2806 are applied is 27.5 N, 40 N, 75 N, 100 N and 125 N for the Nos. 1, 2, 3, 4 and 5 class floor hinges and door closers, respectively. This study compared the differential pressure and opening force limits of floor hinges and door closers with the values specified in NFSC 501A and found that they exceeded the criteria specified in NFSC 501A. Therefore, it is necessary to reflect the differential pressure and smoke control wind speeds as well as the opening forces specified in NFSC 501A on the design of floor hinges and door closers. The installation conditions of floor hinges and door closers of access doors differ depending on the type and name of a smoke control damper. This study found that Nos. 1, 2 and 3 floor hinges and door closers could be installed for access doors with low differential pressure and that Nos. 1 and 2 floor hinges and door closers could be installed for access doors with normal differential pressure.

본 연구의 목적은 제연구역 출입문의 최적 설계를 위한 플로어힌지(floor-hinge) 및 도어클로저(door closer)의 기준을 제시하는데 있다. 차압에 대한 개방력은 60 Pa일 때 60.75 N, 40 Pa일 때 40.5 N, 32.5 Pa일 때 32.91 N, 12.5 Pa일 때 12.66 N 등이다. KS F 2806의 기준을 적용한 플로어힌지 및 도어클로저의 개방력은 No.1은 27.5 N, No. 2는 40 N, No. 3는 75 N, No. 4는 100 N, No. 5는 125 N 등이다. 차압과 플로어힌지 및 도어클로저의 개방력을 NFSC 501A의 개방력 제한값과 비교한 결과 기준을 초과하는 것으로 확인되었다. 따라서 NFSC 501A 차압과 방연 풍속을 설계에 반영하는 것뿐만 아니라 개방력도 설계에 반영할 필요가 있다. 제연댐퍼의 종류에 따라 출입문의 플로어힌지 및 도어클로저의 설치 조건은 호칭에 따라 다르다. 저차압용의 경우는 No. 1, No. 2, No. 3의 설치가 가능하며, 일반 차압용의 경우에는 No. 1, No. 2의 설치가 가능하였다.
