How to Adjust the Connection Angle of Hyperbolic GRC Panels to Steel Structures?

In the field of modern architectural decoration, double-curved GRC panels have become the preferred choice for exterior wall decoration of numerous landmark buildings thanks to their unique aesthetic forms and material properties. The adjustment of the connection angle between double-curved GRC panels and steel structures, a key factor affecting both building safety and aesthetics, has always been a major focus for designers and construction teams. Qinglong Group, with 28 years of experience in detailed design, manufacturing, and construction of UHPC/GRC/GRG/GRP materials, has accumulated extensive practical experience in this process. This article provides professional solutions for industry peers from three dimensions: technical principles, key process points, and case applications.

The core of adjusting the connection angle between double-curved GRC panels and steel structures lies in balancing material properties with structural requirements. GRC (Glass Fiber Reinforced Concrete) offers the advantages of being lightweight, high-strength, and flexible in shaping, but the irregularity of double-curved forms makes the design of connection nodes with steel structures challenging. Deviations in connection angle may not only cause stress concentration, leading to panel cracking or detachment, but also compromise the smoothness of the building's overall curved surfaces. Therefore, adjustment work must begin at the detailed design stage, combining 3D modeling technology with on-site measured data to achieve precise positioning.

At the technical implementation level, Qinglong Group adopts an innovative solution of “digital pre-assembly + modular adjustment”. First, BIM technology is used to build 3D models of the double-curved GRC panels and steel structures, simulating stress conditions at different angles and optimizing the position and angle parameters of connection nodes. During production, CNC machining technology is used to manufacture connectors with adjustment slots, ensuring that angles can be fine-tuned on site via bolts with errors controlled within ±0.5°. During construction, 3D laser scanning technology is used to monitor installation accuracy in real time, combined with Qinglong's self-developed angle adjustment tooling, achieving “millimeter-level” adjustment and ensuring smooth transitions of the double-curved surfaces.

Differentiated strategies are required for connection angle adjustment to meet the needs of different architectural scenarios. For example, on the double-curved exterior walls of cultural buildings such as grand theaters, the Qinglong team focuses on the dynamic load balance between panels and steel structures, using elastic connectors to absorb stresses caused by thermal deformation; while in special-shaped sunshade panel projects for commercial complexes, greater emphasis is placed on the convenience and efficiency of angle adjustment, adopting prefabricated angle adjustment modules to shorten construction periods. In addition, the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), which Qinglong Group participated in developing, sets out detailed specifications for the design and construction of connection nodes for double-curved components, providing an authoritative technical reference for the industry.

As a leading domestic custom manufacturer of UHPC/GRC/GRG/GRP, Qinglong Group has always upheld the mission of “creating aesthetically beautiful buildings”, deeply integrating technological innovation with engineering practice. From the translucent concrete project of the Century Plaza renovation on East Nanjing Road to the double-curved GRC curtain wall of the Dongguan Women and Children's Activity Center, Qinglong has achieved precise realization of complex architectural forms through its full-chain service capabilities. In the future, Qinglong will continue to focus on the R&D and application of new decorative materials, providing designers and owners with more professional solutions and driving the high-quality development of the architectural decoration industry.
