装配式钢结构建筑用外墙板的研究及应用进展

Research Progress of Exterior Wallboards for Prefabricated Steel Structures

装配式钢结构建筑在我国的快速发展对与其配套使用的外墙板系统的连接性能及经济指标提出了更高的要求。基于大量的国内外文献检索,对外墙板的类型、受力性能以及连接构造等方面的研究及应用进展进行了总结,分析了各类外墙板与主体结构连接节点的优缺点,总结了目前外墙板与装配式钢结构连接节点存在的主要问题。发现外墙板材料方面主要存在耐久性差、能耗大,环境效益差、综合性能低等问题,外墙板与主体结构连接节点存在设计的标准化程度低、制作的工业化及自动化程度较低、节点形式复杂,可操作性差等问题。最后,指出了目前推广应用存在的关键瓶颈,并对今后的研发方向提出了合理化建议。

With the rapid development of prefabricated steel structures in our country,a higher request has been put forward for the connection performance and economic index of exterior wallboard system.Based on a large number of literature retrieval at home and abroad,the research and application progress of exterior wallboards in the types,mechanical properties and connection structure were summarized,the advantages and disadvantages of various types of exterior wallboards and main structure connection joints were analyzed,and the main problems existing in the connection joints of exterior wallboards and fabricated steel structures were summarized.It was found that the exterior wallboards materials mainly showed poor durability,high energy consumption,poor environmental benefits,low comprehensive performance problems,the connection joints between exterior wallboards and the main structure also remained some problems,such as poor standardization in design,poor industrialization and automation in production,complex joint form,and poor operability.Finally,the key bottleneck existing in the current application was pointed out,and some reasonable suggestions for the future development direction were put foward.
