Research on the Key Technology of the Construction of the Space Grid and Truss Composite Structure of China Culture Exhibition Center

The main structure of Huaxia Culture Exhibition Center is a combination of space grid + truss structure. The form is complex and changeable. It has high requirements for grid installation, measurement and positioning, deformation control and other construction techniques. This paper proposes the erection of the characteristics of the combined structure. The partial load-bearing scaffolding operation platform is used to carry out the high-altitude bulk construction plan, and the measurement and positioning of the hyperboloid space grid and the installation technology of the welding ball, bolt ball, and space truss composite structure are analyzed and scientific solutions are proposed to ensure The precision and construction quality of grid installation.
