主要針對懸吊式輕鋼架天花板之煙洩漏量進行研究,參考CNS 15038之規範要求及試驗原理,建置ㄧ套量測空氣洩漏量之設備,並提供詳細之組裝細節供使用者參考,本研究之測試方法為首創,藉由實尺寸之測試艙,進行天花板之遮煙性能研究,並針對不同天花板材質、天花板尺寸及施工方式,配合流體力學之學理,經過總計405次之試驗,提出不同尺寸及不同材質之天花板之洩漏量評估方式。研究中發現天花板材質不同,即使天花板尺寸相同,會產生不同之洩漏量。當天花板材質相同,而天花板尺寸不同時,並不是板材尺寸越大時,洩漏量會越大,最大片之板材造成之洩漏量反而是最小,這個現象非常特別。本研究並提出ㄧ個天花板整體之洩漏量評估表,未來可提供計算該非火災室之煙洩漏量值,進而可推估其煙下降時間以利逃生避難設計。本儀器設備經證明對於天花板有正確之洩漏量檢測能力,未來如延伸系統設計原理,可應用於其他防火產品之遮煙能力檢測。
The key focus of the research is on the smoke leakage rate from suspended ceiling system, referencing CNS 15038 norm and its experimental principles to build a set of monitoring equipment for measuring air leakage rate and the provision of detailed assembly details for users’ reference. Through the real-size test chamber, the smoke insulation performance of the ceiling is studied. Targeting the different ceiling materials, ceiling panels dimensions and construction methods, in keeping with the scientific principles of fluid mechanics, a total of 405 tests are carried out to come up with the means of appraising the leakage rate of ceiling panels of different sizes and materials. The study found that with the ceiling panel material quality being different, even if the ceiling size is the same, different leakage rates could occur. When the material quality of the ceiling panels is the same and the ceiling size is different, it is not that the larger the size of the panel, the greater the leakage rate but the smallest leakage rate is caused by the largest panel and this is a very special phenomenon. This study also presents a leakage rate assessment table for entire ceiling panels, which will provide future calculations of the smoke leakage rate of the non-flame room, which can be extrapolated to assess the time of smoke decline and conducive for evacuation design. The apparatus has been proven to have proper leakage rate detection capability for the ceiling panels. In the future, the design principle of the extended system can be applied to the inspection and testing of smoke insulation capability of other fire prevention products. In turn, it can be estimated when the smoke has fallen to facilitate escape design.
