摘要
管桁架结构是在网架结构的基础上发展起来的,安装采取“地面拼装、整体吊装、空中对接”的原则,地面拼装过程中可对多榀桁架同时拼装作业,其主要适用于大跨度建筑结构中,不仅满足建筑质量性能方面需求,而且减少钢结构使用量。论文依托天祝藏族自治县体育场建设项目,利用软件对大跨度超高悬挑变曲率管桁架节点接头、复杂构造节点进行优化处理,最终大幅提升构件加工速率及成品优品率,现场拼装安装精度高,相较传统施工方法,不仅满足了建筑结构质量要求,而且大幅度提升施工速率。
The tube truss structure is developed on the basis of the grid structure,the installation adopts the principle of“ground assembly,overall lifting and air docking”,in the process of ground assembly,multiple trusses can be assembled simultaneously,it is mainly suitable for long span building structure,not only to meet the building quality performance requirements,but also reduce the use of steel structure.This article relies on Tian zhu Tibetan Autonomous County stadium construction project,the software is used to optimize the joint joints of long-span ultra-high cantilevered variable curvature tube truss and complex structural joints,finally greatly improve the processing rate of components and the rate of finished products,high precision of on-site assembly and installation,compared with traditional construction methods,not only meet the quality requirements of the building structure,but also greatly improve the construction speed.
