How to perform high-altitude bulk loading of space frame processing structures?

  1. When using small assembly units or members for direct assembly at high elevations, the sequence should ensure assembly accuracy and minimize cumulative errors. When using the cantilever method, the structure should first be assembled into a system capable of supporting its own weight, followed by gradual expansion. During the assembly process of space frame fabrication, the positions of reference axes, elevations, and deviations should be checked at all times, and corrections should be made promptly. 2. When erecting assembly scaffolding, the support points on the scaffolding should be located at the lower chord nodes. The scaffolding should be verified for its load-bearing capacity and stability, and load testing may be conducted as necessary to ensure safety and reliability. Measures should be taken under the scaffolding columns to prevent foundation settlement. 3. During the removal of the scaffolding, individual support points should be prevented from bearing concentrated...
