随着社会主义现代化建设的推进,城市场馆应运而生。阶梯式肋环形网格管桁架由于其低碳环保、经济实用、制作方便、整体性强而被应用于场馆工程中。城市场馆的改建工程、新建工程,若吊装条件允许,采用传统的单榀吊装能够满足要求,但需要投入临时支撑等,措施较大,对场地使用面积较大,高空作业定位点较多。组合单元安装法适合于城市场馆的改建、新建工程和受现场场地限制无法散件吊装时的情景,特别适合阶梯式肋环形网格管桁架工程的安装。
With the promotion of socialist modernization, urban venues came into being. Because of its low-carbon environmental protection, economical and practical, convenient fabrication and strong integrity, the stepped rib ring grid pipe truss is applied to stadium construction. Rebuilding projects and new construction projects of urban venues will be able to meet the requirements if they are hoisted by conventional hoisting. However, they require temporary support and other measures. The measures are relatively large and the space used is relatively large. There are many locations for high-altitude operations. The combination unit installation method is suitable for the reconstruction of urban venues, new construction projects and the scene when the site can not be suspended by pieces of lifting, especially for the installation of stepped rib ring grid pipe truss project.
