摘要
山东省某体育馆钢罩棚采用大悬挑空间倒三角自平衡管桁架结构。在异型桁架安装过程中,对地面拼装、高空吊装、桁架精确定位及三维激光扫描检测、临时支撑体系砂箱卸载等采取了一系列技术措施,实现快速精确安装。
Steel shed of a gymnasium in Shandong province adopted a large cantilever space upside-down triangular self-balancing tube truss structure.During installation of the specially-shaped truss,a series of technical measures were adopted for ground assembly,lifting,accurate positioning of truss,tri-dimensional laser scanning detection and sand box unloading of temporary support system,etc.,realizing fast and accurate installation.
