Precise Positioning Technology for Embedded Parts in Double-Curved GRC Panels

The positioning accuracy of embedded parts in double-curved GRC panels directly affects installation quality and structural safety. Through three technologies—digital design, precision machining, and intelligent inspection—Qinglong Group controls embedded part positioning error within ±1.5mm, ensuring precise connection of thousands of joint points.

Digital design determines optimal positions. Stress distribution is calculated through finite element analysis to place embedded parts in low-stress zones. In the Wuhan Han Show Theatre project, Qinglong Group used parametric algorithms to optimize embedded part spacing, reducing the number of connection points by 20% without compromising safety. Embedded part orientation is determined through normal vector analysis to ensure reasonable load bearing. Design data is converted directly into machining code, avoiding secondary input errors.

Precision machining ensures accurate positioning. Five-axis machining centers drill precise holes in molds with position error ≤±0.5mm. Qinglong Group developed a magnetic positioning system in which embedded parts self-align through magnetic bases, improving efficiency 10 times over manual work. In the Hainan International Convention and Exhibition Center project, robots were used to implant embedded parts with repeat positioning accuracy of ±0.2mm and the capability for 24-hour continuous operation.

Intelligent inspection verifies final accuracy. Industrial CT scanning is used on finished panels for non-destructive testing of embedded part positions and concrete coverage. Qinglong Group conducts a full inspection of every panel before shipment and establishes digital records. During on-site installation, laser trackers re-verify positions to ensure foolproof accuracy. This whole-process precision control lays the foundation for the safe installation of double-curved GRC panels.
