Abstract：
The project is a profile steel reinforced concrete frame structure, covering a building area of 30?440?m2, and the roof is made of wide-span archaized four-rib square grid structure. This paper introduced the fabrication and division of steel grid, lifting process, setting and unloading of temporary support. Relevant quality control and safety measures were proposed. Based on analysis and application of installation techniques, it was proved that the installation technique could save construction schedule, improve construction efficiency and safety the engineering requirements.
