Combined with Root Interconnection National Headquarters Building project, the structure oftubular interconnection node column is analyzed. The structural characteristics of display-level tubularinterconnection node and the control difficulties of processing and manufacturing deformation areintroduced in detail. Through the production practice of the factory, a new process of processing andmanufacturing deformation control with strong technical practicality and high precision control issummarized,which ensures the smooth implementation of the project node.
