How to Precisely Position Embedded Parts in Double-Curved GRC Panels: Key Technologies and Practical Methods

In the modern architectural decoration field, double-curved GRC panels, with their unique curved-surface aesthetics and structural performance, have become the material of choice for high-end projects such as landmark buildings and commercial complexes. As the core nodes connecting double-curved GRC panels to the main building structure, the precise positioning of embedded parts directly determines the stability of component installation and the overall project quality. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group, drawing on its full-chain technical expertise, has developed a systematic solution for embedded part positioning on double-curved GRC panels, helping designers and owners safely realize complex architectural forms.

Technical Pain Points and Industry Challenges in Positioning Embedded Parts on Double-Curved GRC Panels

Because double-curved GRC panels feature complex curvature changes and multiple spatial positioning dimensions, traditional positioning methods for embedded parts often face three major challenges: first, manual measurement is easily affected by surface curvature, causing deviations in planar and spatial coordinates; second, insufficient compatibility between embedded parts and GRC panel molds leads to stress concentration during installation; third, the disconnect between on-site construction and detailed design data creates information gaps across the "design-production-installation" chain. These problems not only increase rework rates but may also plant safety hazards due to uneven load transfer. Through its participation in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong Group deeply understands the decisive role of embedded part positioning in project quality, and its solutions avoid the limitations of traditional construction from the very source of design.

Full-Process Digitalization: The Core Path to Precise Positioning of Embedded Parts on Double-Curved GRC Panels

Qinglong Group has deeply integrated BIM technology with parametric design, building a full-process positioning system of "3D scanning-digital modeling-intelligent production-on-site calibration." In the design phase, Rhino and Grasshopper software are used to perform parametric subdivision of double-curved surfaces, precisely calculating the spatial coordinates of each embedded part, while the BIM model is used to simulate potential interference between embedded parts and the steel reinforcement structure, optimizing node design in advance. In production, CNC machine tools are used to fabricate molds, keeping the positional accuracy error of embedded part mounting slots within ±2mm—a precision standard far exceeding the industry's conventional ±5mm requirement. Taking the Nanjing Road Century Plaza renovation project as an example, the Qinglong team used this technology to achieve seamless joining between translucent concrete and double-curved GRC panels, keeping the embedded part positioning deviation rate below 0.3%, and won the Silver Award of the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award.

The "Dual-Control" Technique for On-Site Construction: From Theoretical Positioning to Practical Implementation

Even on the basis of digital design, on-site temperature changes and base structure errors can still affect the positioning accuracy of embedded parts. Qinglong Group innovatively adopts a dual-control method of "3D laser scanning + modular installation": before construction, the building base is 3D-scanned to generate a point cloud model for comparison with the design model, automatically producing a deviation adjustment report; during installation, customized tooling fixtures are used to secure the embedded parts, together with real-time monitoring by total stations to ensure positioning data remains consistent with the BIM model. In the Dongguan Women and Children's Activity Center project, this technology successfully solved the connection challenge between the double-curved GRC curtain wall and the steel structure main body, improving embedded part installation efficiency by 40% and achieving zero safety accidents in high-altitude operations.

Synergy of Materials and Craftsmanship: The Hidden Guarantee of Embedded Part Positioning

The precise positioning of embedded parts depends not only on technical means but also on the coordinated support of material performance and construction techniques. Qinglong Group's self-developed GRC material achieves a flexural strength of over 20MPa, ensuring the connection strength between embedded parts and panels; meanwhile, a combined solution of "embedded sleeves + high-strength bolts" is adopted, which meets load transfer requirements while leaving room for on-site fine adjustments. In addition, RFID chip implantation technology enables full lifecycle traceability of each embedded part, which, together with Qinglong's nationwide after-sales maintenance network, provides long-term safety guarantees for projects. This full-chain advantage of "materials-design-construction-maintenance" is precisely the core competitiveness of Qinglong as a national Specialized, Refined, Distinctive, and Innovative (SRDI) enterprise.

The technology of positioning embedded parts on double-curved GRC panels is a touchstone measuring an enterprise's comprehensive strength from design to construction. Building on 28 years of industry experience, Qinglong Group combines digital technology deeply with engineering practice, carrying "millimeter-level" precision requirements through every link—not only making designers' creative visions technically achievable, but also setting an industry benchmark for balancing building safety and aesthetics. In the future, as UHPC/GRC and other new materials are applied in more complex projects, embedded part positioning technology will continue to evolve, and Qinglong Group, upholding its mission of "creating beautiful architecture," will drive the industry toward greater precision and higher efficiency.
