Application and Practical Exploration of Digital Technology in GRC Curtain Wall Installation

As modern architectural aesthetics increasingly pursue irregular and personalized forms, GRC (Glass Fiber Reinforced Concrete) curtain walls, with their advantages of lightweight high strength and flexible styling, have been widely applied in high-end buildings such as grand theaters and commercial complexes. However, traditional installation modes face pain points such as insufficient precision in detailed design, large on-site construction errors, and difficulty in quality traceability. As an industry-leading enterprise with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group has leveraged digital technology to build an intelligent solution covering everything from design to operation and maintenance, redefining the technical standards for GRC curtain wall installation.

I. Digital Design: A Precision Revolution from Drawings to Models

In the early stage of GRC curtain wall installation, digital design is the core of efficiency improvement. Qinglong Group adopts BIM (Building Information Modeling) technology and parametric design tools (such as Rhino+Grasshopper) to convert two-dimensional drawings into three-dimensional visual models. Taking a landmark convention and exhibition center project as an example, its hyperbolic GRC curtain wall features such complex shapes that traditional CAD design could hardly resolve the interlocking relationships between components. Through the clash detection function of the BIM model, 37 design conflict points were identified in advance, avoiding on-site rework; parametric design enabled the batch generation of more than 6,000 irregularly shaped GRC components, increasing design efficiency by 40%. This digital design capability enables Qinglong to precisely respond to designers' demands for "millimeter-level" shape accuracy, laying a solid foundation for subsequent installation.

II. Intelligent Manufacturing: Digital Control of GRC Component Production

Digital technology is not only reflected in the design stage but also runs through the production of GRC components. Qinglong's Guangxi production base has introduced an industrial internet platform to collect and analyze real-time data on key processes such as mold processing, material proportioning, and curing cycles. By embedding RFID chips into each GRC component, an "identity file" is established, enabling full-process traceability from raw materials to finished products. In a commercial complex project, the system successfully increased the component pass rate from 92% to 98.5%, while shortening the production cycle by 15% through intelligent scheduling algorithms. This "digital factory" model ensures the standardized production and quality stability of GRC components, providing reliable support for precise on-site installation.

III. Intelligent Installation: Collaborative Innovation of 3D Scanning and Modular Construction

On-site installation is a key link in GRC curtain wall projects, where digital technology plays a core role in "cost reduction and efficiency improvement." The Qinglong team adopts 3D laser scanning technology to measure building structures with millimeter-level precision, generating point cloud models to compare with BIM design models and quickly locating structural deviations. During installation, combined with total stations and AR (Augmented Reality) technology, visual guidance for component positioning is achieved, transforming the "experience-dependence" of traditional installation into "data-driven" processes. In a museum project, this technology kept the installation error of the GRC curtain wall within ±2mm, far exceeding the industry standard of ±5mm, while reducing the construction period by 20%. In addition, the introduction of the modular installation concept breaks down complex GRC curtain walls into standardized units, further improving on-site assembly efficiency.

IV. Smart Operation and Maintenance: Digital Management of the Full Life Cycle

The application of digital technology extends to the later operation and maintenance stage of GRC curtain walls. The smart O&M platform developed by Qinglong Group uses sensors to monitor real-time data such as temperature deformation and stress status of GRC components, and combines BIM models to achieve fault warning and maintenance decisions. For example, in a landmark building in a coastal city, the system successfully issued early warnings for 3 loose connector problems caused by sea wind loads, avoiding potential safety hazards. This "digitalization + O&M" model not only extends the service life of GRC curtain walls but also embodies Qinglong's brand promise of "full-chain service."

As a national high-tech enterprise and a participant in the formulation of GRC industry standards, Qinglong Group has always driven industry development through "technological innovation." The deep application of digital technology in GRC curtain wall installation not only solves the precision and efficiency pain points of traditional modes but also promotes the transformation of the architectural decoration industry toward "intelligent construction." In the future, Qinglong will continue to explore the integration of cutting-edge technologies such as AI and digital twins with UHPC/GRC/GRG/GRP materials, providing designers and owners with more innovative solutions and fulfilling its corporate mission of "creating beautiful architecture."
