三亚国际免税城钢结构体系测量安装技术

摘要

Combined with the measuring and installing construction for steel structure of the main and back entrance in Sanya CDFG Mall,introduced the measuring and installing technology for complex steel structure composite system. Using the technology of surveying control network layout,3D modeling, ground assembly,segmentation lifting,unloading monitoring,and so on,carried out the spatial positioning surveying,structural members installing for steel box arch,steel truss,spatial reticulated shell. Ensure the structure is reasonable for loading and deformation was stable.%结合三亚国际免税城工程主次入口钢结构的测量安装施工，介绍了复杂形式钢结构组合体系的测量与安装技术。采取测量控制网布设、三维建模、地面拼装、分块吊装、卸载监控等技术，对钢箱拱、钢桁架、空间网壳实施地面与空间定位测量、结构构件安装，确保结构体系受力合理、变形稳定。
