China Space Frame Architecture of Nanjing Park Project factory and manufacturers

Space Frame Architecture of Nanjing Park Project

The most commonly used installation method in the installation and construction of space frame structure: according to the conventional construction process, follow the corresponding process regulations. The following aspects should also be noted: A. The installation sequence of the space frame architecture. Install the steel structure space frame structure within the coverage area of the support first. Before installing the cantilever grid, make sure that the space frame structure within the coverage area of the support has been installed correctly, the structure is reliable, and the welding seam of the support has been designed according to the design. required and qualified. Then when installing the overhanging parts, it should be installed symmetrically from the middle to both sides. Symmetrical installation from the middle to both sides can ensure the symmetrical force of the structure, prevent uneven force from causing asymmetric deformation of the structure that is difficult to adjust, and prevent the components from being difficult to correctly install in place.
