Abstract
In foreign countries, a non-insulated fire glazed window is permitted in fire compartment restricting the use and size, but on the domestic side, not permitted. So, there is a need to confirm the fire resistance of the domestic non-insulated fire glazed window and to evaluate the fire safety of that. In this study, the fire resistance tests of 4 types of windows were conducted depending on window area, and the measured radiant heat fluxes and temperatures were evaluated in fire safety. As a result, we suggested the window/wall area ratio secured the fire safety.
Key Words: Non-insulated fire glazed window; Fire safety; Fire test; Heat flux; Area ratio
요지
국외에서는 용도 및 창의 크기를 제한하여 방화구획에 비차열 방화유리의 사용을 허용하는데 반해 국내에는 그 사용이 불가능하다. 따라서, 국내의 비차열 방화유리의 내화성능을 확인하고, 화재안전성을 평가해 볼 필요성이 있다. 본 연구에서는 비차열 방화유리에 대하여 면적별로 4가지 실험체를 구성하여 내화실험을 실시하고, 측정된 복사열유량 및 온도를 적용하여 화재안전성을 평가하였다. 그 결과 화재안전성을 확보하면서 사용이 가능한 면적비를 제안하였다.
핵심용어: 비차열 방화유리; 화재안전성; 내화시험; 열유량; 면적비
