Digital Empowerment for Precise Alignment of Double-Curved GRC Panels: Full-Process Control from Design to Installation

Precise jointing is the dual guarantee of architectural aesthetics and structural safety for double-curvedGRC panels, and digital technology has made zero-error curve joining a reality. As an industry leader deeply engaged in theUHPC/GRC/GRG/GRP field for28 years, Qinglong Group has witnessed the revolutionary transformation that digital technology has brought to double-curvedGRC panel construction. Leveraging its full-chain technical advantages, it has provided precise jointing solutions for numerous landmark projects worldwide.

Double-curvedGRC panels, with their complex shapes and varied curved surfaces, are prone to gap deviations and angular misalignment under traditional jointing methods, but digital technology has solved this problem at the design source. Qinglong adoptsBIM full-process modeling technology. In the Guangxi New Media Center project, through parametric design withRhino andGrasshopper, the spatial coordinates and curvature parameters of each double-curvedGRC panel were accurately entered into the model, achieving digital linkage between component production and installation. No two of the project's11500 square meters of double-curved exterior wall panels are identical, yet millimeter-level jointing precision was achieved.

The application of 3D laser scanning technology makes on-site jointing more controllable. In the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project, the Qinglong team used a 3D laser scanner to perform a panoramic scan of the steel structure substrate, generating point cloud data that was compared with the design model in real time to automatically correct installation deviations. Combined with Qinglong's self-developed intelligent adjustable supports,XYZ three-axis fine adjustment can be achieved, ensuring the precise jointing of double-curvedGRC panels under complex working conditions. The project won the Luban Award for its perfect jointing craftsmanship.

The coordinated linkage of digital production and installation is the core of precise jointing. In the colorful openwork carved panel project of the Nanning Liyuan Hotel, Qinglong used CNC machining equipment to achieve mold precision of±0.5mm, keeping component production errors at an industry-leading level. During the installation phase,BIM technology was used to simulate the construction path, combined with the BeiDou positioning system to guide hoisting, realizing full-process digital traceability of double-curvedGRC panels from factory to site, ensuring that the jointing precision is highly consistent with the design concept.

The in-depth application of digital technology has transformed the precise jointing of double-curvedGRC panels from a technical challenge into a standardized process. As an enterprise that participated in formulating the "Technical Standard for the Building Application of Glass Fiber Reinforced Cement (GRC)", Qinglong has integrated years of digital practical experience into industry standards, providing designers and owners with full-chain solutions from detailed design to after-sales maintenance. In the future, Qinglong will continue to drive the upgrading of double-curvedGRC panel applications through technological innovation, enabling more buildings to achieve the perfect unity of aesthetics and functionality.
