Research on the Construction Technology and Design of the Protection Layer of Concrete Filled Steel Tube Column

摘要: 通过对钢管混凝土圆柱保护层的计算分析及特点介绍，得出符合设计要求的防火保护层厚度。根据现场实际情况，优化施工工序，总结出符合实际的施工工艺。不但保证设计的防火要求，同时在施工过程中对关键工序进行控制。使得该施工技术可以在类似工程中推广应用。

Abstract: Through the calculation analysis and characteristic introduction of the protective layer of con-crete filled steel tube columns, it is concluded the protection layer thickness which complies with the design requirements. According to the actual site condition and optimization of the construction process, it sums up the actual construction process which ensures the design of fireproof requirement and at the same time controls the key process in the construction process. The new technology makes wide prospect and extensive popularized significance.
