火災時における耐熱強化ガラスの破損要因に関する実験的研究: 単板ガラス•複層ガラス•Low-E複層ガラスについて

摘要

For setting the criteria of the performance of the fire preventive tempered glass, the temperature data of the glass were obtained by fire tests, and checked the breakage factor of the glass. Fire tests were performed for not only Single glass pane but also Double-glazed glass pane and Low-Emissivity Double-glazed glass pane. Findings are as follows. 1. Temperature difference(ΔT) in the glass on fire tests and Surface compression of the glass are closely relevant. 2. Temperature difference(ΔT) in the glass on fire tests and Emissivity value of Low-E coating glass are closely relevant. 3. Therefore, Performance of fire preventive glass can be evaluated by Temperature Difference(ΔT) in the glass, Surface Compression of the glass and Emissivity value of Low-E glass can be a substitute property on fire preventive tempered glass performance criteria.%耐熱強化ガラスの性能判定基準を構築する基礎的知見を得るため、本実験では『火災時のガラスの破損要因に着目』して、限られた実験条件下ではあるが、耐熱強化ガラスの単板ガラス•複層ガラス•Low-E複層ガラスの温度差ΔT、破損の有無、並びに温度性状を確認するための遮炎性能試験を実施した。得られた知見は以下の通りである。
