桁架檩条在大柱距钢结构建筑中的应用

The application of truss purlin in large span steel structure buildings

桁架檩条作为一种大柱距屋面檩条形式,是为了实现当下钢结构建筑大空间、大跨度的要求而开发应用的,填补了常规檩条与网架结构之间的空白。文章结合工程实例详细介绍桁架檩条的形式、结构布置及构造,以及与传统檩条形式的比较,总结出桁架檩条体系的优势及发展前景。

As a kind of space truss purlin roof purlin form, in order to achieve the current steel structure building with large space and large span requirements and application development, fills the gap between conventional and purlin truss structure. In this paper, combined with engineering examples, introduces the structure of truss purlin form, layout and structure, and compared with the traditional form of the purlin summed up the advantages and development prospects, truss purlin system.
