摘要
郑州大学综合体育场钢屋盖呈月牙状造型,采用钢管桁架结构,结构形式独特,跨度较大,安装高度高,杆件种类繁多,构件制作精度要求高,现场施工难度大。针对大跨度钢管桁架钢屋盖的结构特点及施工中存在的难点,研究了先现场预拼装再吊装拼接的桁架施工技术,探讨了关键施工工艺。
The steel roof of Zhengzhou University Sports stadium presents crescent-shaped styling constructed with steel pipe truss structure. The structure form of the roof is unique,the span is big,the mounting height is high,the variety of bars is wide,the precision of component production is high,and the site construction is difficult. In order to solve the construction difficulties of large-span steel truss roof,the construction technology was adopted, with the components first pre-assembled and then assembled. The key construction program was discussed. The construction of large-span steel truss roof was completed successfully.
