國內許多中小型工廠都屬鐵皮屋形式搭建,鐵皮屋易於施工、建築速度快且經濟便宜,以致人民接受度高而普遍興建。常見廠房住宅合併使用,即上層為一般住宅使用,下層為廠房加工作業區。本案例就是典型的鐵皮工廠,麵包店鐵皮加蓋的麵包製作區起火後,波及旁邊內部囤積大量紙張印刷廠,一旦發生火災,常常造成重大人員傷亡及財物損失。 本研究是以新莊區麵包店火災為研究對象,並利用「FDS 」軟體進行火場模擬分析,以電腦數值模擬鐵皮屋廠房火場各物理現象,探討火場中的煙流、CO濃度及上層溫度等參數的變化,以了解火場中溫度傳遞、濃煙擴散等狀況,針對火場主要影響因素,改變各種不同參數設定,探討相關參數對火災的影響,並期許本研究成果能提供設計人員對鐵皮屋廠房在防火工程有參考價值,以降低人員傷亡及財產損失。
In Taiwan, many middle and small factories are built in the type of iron-sheet buildings which are easily to be constructed with high speed and low expense. Therefore, it is commonly accepted and constructed by the people here. Normally it is used both for workshop and housing, that is, the upper floor for general housing use and the lower floor for products processing area. This case is a typical iron -sheet factory for processing, the bakery tin-covered bread production area is on fire, it spread to the adjacent printing plant in which has accumulated a large number of papers. Once the fire happens, usually causes significant personnel casualty and property losses. This research takes the Bakery in Sinchuang District as the object of study, and uses the Fire Dynamics Simulator (FDS) software for fire simulation and analysis. Computational method simulates the various physical phenomenon of the fire scene and discusses the changes of parameters about smoke stream, carbon monoxide (CO) concentration and upper layer temperature, in order to understand the temperature transmission and the smoke transportation in fire scene. Focusing on the major causes of the fire scene, changing various parameter sets, and discussing the influences of related parameters to the fire, hoped that this research result is worth a reference to provide the designers for fire protection project on the iron-sheet factory, in order to reduce the personnel casualty and property damage.
