摘要

台灣的經濟起飛與產業型態的轉變，讓人們賴以居住的房子也從早期的低樓層建築改變為高樓層公寓。近幾年來，建築物為了運輸的方便往往都會設置昇降機。昇降機在建築物的構造中扮演著垂直連接各樓層的角色，但是當建築物發生火災時，垂直貫穿建築物的昇降機井道可能就成為火災延燒擴大的途徑。
垂直防火區劃可以在某段時間內將火勢控制在建築物的該樓層範圍，以防止其從起火層沿著建築物高度的方向朝其他樓層垂直的蔓延。在這樣的設計中，昇降機的乘場門往往都是防火區劃中最脆弱的開口部。
研究中採用有限元素分析軟體ANSYS模擬分析昇降機防火門的結構，觀察其於火災高溫環境下的結構強度變化和不同設計因子下的剛性特質。針對不同的材料及設計因子，探討昇降機防火門於高溫環境中的翹曲變形。期以提供未來設計昇降機防火門或規劃建築物的防火區劃時一個量化的參考依據。

Taiwan's economy is growing rapidly and industrial type is changed that makes people changing their living houses from low-rise buildings of the early style to high-rise apartments. In recent years, the building is often installed with lift for transport convenience. The lift is playing a role of vertical connections on each floor in the building, but when building fire occurs, the vertical lift shaft through the building may be expanded to become the way of fire spread.
Vertical divisions is capable of controlling fire within a certain time in the floor area to prevent the building fire spread vertically from the fire floor expanding toward the other floors of the building. In this design, the lift doors are often the most vulnerable openings in fire division.
This study is using the finite element analysis software ANSYS for simulating the structure of lift fire doors, changes of the structural strength has been observed under high temperature and rigidity under different characteristics of the design factors. The deflection of lift fire doors has been probed by different materials and design factors under the high temperature. The simulation result hopes to provide a reference for future planning of lift fire doors’ design and a quantitative data in building fire division.
