【摘要】 排烟(气)道是重要的建筑构配件,可减少火灾损失、确保人民生命、财产安全。采用标准实验方法对排烟(气)道耐火极限进行了测试,研究了不同管道厚度、不同水泥砂浆厚度下排烟(气)道的耐火完整性与耐火隔热性,实验结果对于JG/T 194-2018《住宅厨房和卫生间排烟(气)道制品》标准的实施有重要的参考价值,就此提出了相应的改进措施和建议,以优化排烟(气)道制品。更多还原

【Abstract】 Ventilation duct is an important building component in the building, which can reduce fire loss and ensure the safety of people’s life and property. The fire resistance limit of ventilation duct was tested by standard experimental method, and the fire integrity and fire insulation of ventilation ducts with different pipe thicknesses and different cement mortar thicknesses were studied. The experimental results have important reference value for the implementation of JG/T 194-2018 Ventilating duct for residential kitchen and bathroom. The corresponding improvement measures and suggestions are put forward to optimice the test procedure for ventilation ducts.更多还原
