台灣都市發展集中高樓林立，昇降機為垂直空間運輸以及活動必不可少的工具。「建築技術規則」第五十五條規定六層以上之建築物，至少應設置一座以上之昇降機（電梯）通達避難層。建築物發生火災時，昇降機豎穴可能成為火災延燒與煙毒蔓延的路徑。而擴大至各樓層造成人員傷亡。
一般昇降機層門門縫過大狀態下，會造成豎穴防煙區劃不完全，使煙毒有侵入流竄的可能。現今國內已有豎穴防煙區劃及防火設備遮煙性之規定，但施行日未公告。本研究參考CNS15038建築用門遮煙性試驗法，BS-EN 81-58 Part 58:Landing doors fire resistance test設計試驗裝置。以一般昇降機層門為試體，進行遮煙性實驗。並針對昇降機層門裝置做構造上的探討，並提出改善昇降機層門各門縫之方法與裝置並分析其成效，試驗結果顯示一般市售昇降機層門之洩漏量在常溫20pa壓差下高達15.8m3/min，而針對其開關方式以(一)增加迴路之方式在上部以及中間門縫改善，(二)加入軟性磁條迴路在左右以及下部門縫改善，先確定改善可以達成BS-EN 81-58中之規範之洩漏量小於3m3/min˙m，再進而提出更有效的改善達到小於CNS15038所規定較嚴格之標準12m3/hr˙m2，而本研究所提出之最佳改善裝置，試驗後顯示可降低洩漏量到3 m3/hr˙m2，能有效確保升降機豎穴防煙區劃安全性。

City advance is concentrated in Taiwan ,more and higher buildings bring elevator become the most essential appliance in city vertical space. Regulation of architectural design article fifty-five define that building of six floors and upward must be installed at least one and upward elevator reach ground plane. When fire occur in building, smoke and fire can travel through building elevator shafts to threaten life at locations remote from the fire.
General elevator door gaps are too large to cause elevator shafts compartments incompletely and smoke and fire can travel through building elevator shafts to another floors. There was regulations of elevator shafts compartments in Taiwan, but haven’t announced and enforced. This study consult CNS15038, BS-EN 81-58 Landing door fire resistance test to design test specimen. Testing general elevator door leakage and advancing improvement on their gaps. Research results show that the leakage of general elevator door are 15.8m3/(min*m2) at 20 Pa, and this requires improvement. Using special labyrinth design and door gaps baffle materials for closed gaps around door of improvement, leakage decreased to 180m3/hr˙m under at 20 Pa and achieved BS-EN 81-58 standard. For more effective way of improvement, leakage decreased to 12m3/hr˙m2 at 20 Pa under and achieved CNS15038. Design of this study can make elevator shafts compartments completely.
