수평차단막 설치에 따른 랙크식 창고의 화재방호성능 개선에 관한 연구

Abstract

A rack-type warehouse is a structure that vertically loads a large amount of goods. When a fire occurs can cause massive damage. In Korea, rack-type warehouses are installed with sprinklers and fire detectors in accordance with national fire safety codes. In case of rack-type warehouse fires in Korea, sufficient fire protection performance could not be secured. In this study, the horizontal barrier was analyzed by fire simulation to improve the fire protection performance of rack type warehouse. As a result of the fire simulation, it was possible to prevent the vertical spread of the fire when the horizontal barrier was installed over a certain length. In addition, in the case of installing a horizontal barrier and installing fire detectors under the horizontal barrier, it was possible to detect the fire early compared to the existing way of fire detector installation. When the horizontal barrier is installed, the temperature distribution under the horizontal barrier is higher than when the horizontal barrier is not installed, and the sprinkler head can be operated early due to the heat collecting effect.
