摘要
某科技竞赛展厅钢结构屋盖主梁采用27m跨预应力索桁架,次梁采用8m跨H型钢,屋面采用彩钢屋面板。本文主要介绍预应力索桁架节点连接构造,索桁架与次梁节点连接构造,上弦支撑布置方式及其与主、次梁节点连接构造,钢结构屋盖施工工法等,可供同类工程设计及施工时参考。
This paper introduces a design scheme about a steel roof system, being composed of main beams and secondary beams, to be used in a science and technology exhibition hall. Detail introduction of Joint＇s connection fabrications about prestressed cable trusses,Joint＇s connection fabrications between the cable trusses and secondary beams, disposition forms of bracing members between upper chords, Joint＇s connection fabrications between the bracing members and main beams as well as secondary beams as well as construction activity of the steel roof are given out. It gives a valuable reference to relevant designs and constructions in engineering.
