摘　　要：随着工程建设的发展,建筑防火的重要性日益突显。对通风空调系统管道而言,防火形式主要有采用耐火风管或风管外壁采取防火保护措施两种,该文结合具体工程实例,对应用较为广泛的金属风管防火板包覆施工技术进行研究,从工艺流程、轻钢龙骨框架、防火板安装三个方面进行了详细阐述,并通过对防火板耐火极限等特征的深入分析,对金属风管防火板包覆系统在建筑工程中的应用价值进行了总结归纳。With the development of engineering construction,the importance of building fire prevention has become increasingly prominent.For the pipeline of ventilation and air conditioning systems,there are mainly two forms of fire protection:fire-resistant air duct,fire protection measures for the outer wall of air duct.Based on a case,this paper expounds the cladding construction technology of the metal wind pipe fire-proof board,describing concretely from three aspects of the technological process,the lightweight steel keel frame and the installation of the fire-proof board.Based on the deep analysis of the fire-resistance limit of the fire-proof board,the value of the cladding system of the fire-proof board of the metal air duct in the building engineering is summarized.
