Analysis of Key Considerations and Implementation Points for Hoisting Plans of Super-Large GRC Shapes

Ultra-Large GRC Shaped Element Hoisting: A Full-Dimensional Analysis from Technical Breakthrough to Engineering Implementation

Driven by the dual forces of contemporary architectural aesthetics and engineering technology, ultra-large GRC (glass fiber reinforced concrete) shaped elements have become the core vehicle for landmark buildings to achieve curved tension and artistic expression. However, as the critical node determining project success or failure, the hoisting process not only tests the professionalism of material performance and structural design, but also requires integrating full-chain capabilities across detailed design, manufacturing, and construction installation. As an industry leader with 28 years of experience in detailed design and engineering implementation of UHPC/GRC/GRG/GRP materials, Qinglong Group presents an in-depth analysis of systematic solutions for ultra-large GRC shaped element hoisting, drawing on the practice of over a thousand large-scale projects.

I. Core Challenges and Technical Prerequisites of Ultra-Large GRC Hoisting

Ultra-large GRC components typically feature heavy individual weight (up to several tons), high geometric complexity (double-curved surfaces, openwork structures), and stringent installation precision requirements (millimeter-level error control). Their hoisting process must resolve three core contradictions: balancing material lightweighting with structural load-bearing capacity, attitude control of irregularly shaped components, and efficiency assurance in multi-process coordination. Through material formula optimization (such as adding basalt fiber to raise flexural strength above 20MPa) and upfront BIM parametric design, Qinglong Group completes hoisting point simulation and stress analysis during the component production stage, laying a technical foundation for on-site construction.

II. Key Dimensions of Hoisting Scheme Design: From Safety Redundancy to Precision Control

1. Hoisting Equipment and Lifting System Selection: Different project scenarios require matching equipment such as crawler cranes, truck cranes, or tower cranes, with key consideration given to the crane's operating radius, rated lifting capacity, and component center-of-gravity offset coefficient. The 300-ton-class hoisting commissioning platform at Qinglong's Nanning production base can simulate the load distribution of lifting points under various working conditions, ensuring rigid connection between lifting devices (such as specially made truss-type lifting frames and vacuum suction cups) and components.

2. Structural Reinforcement and Temporary Support Systems: Finite element analysis software is used to rehearse component deformation during the hoisting process, while modular steel supports or adjustable jack systems enable dynamic fine-tuning of hoisting attitude. For example, in the hoisting of a 12-meter-span GRC curtain wall at a convention and exhibition center, Qinglong innovatively adopted a "staged unloading" process, synchronizing temporary support removal with structural stress release.

3. Dynamic Response Mechanism for Environmental Factors: Hoisting operations must be suspended when wind speed exceeds 10m/s, and thermal expansion and contraction of materials caused by temperature changes must be absorbed through reserved adjustment joints. Qinglong's independently developed environmental monitoring system collects temperature, humidity, and wind data in real time, linking with the hoisting control system to enable intelligent start-stop.

III. Full-Chain Coordination: Closed-Loop Management from Detailed Design to After-Sales Maintenance

As a national-level high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong Group has established a full-process control system covering "design-production-hoisting-acceptance." During the detailed design stage, the Rhino+Grasshopper parametric platform is used to optimize component segmentation and reduce hoisting joints; the production process employs RFID chip implantation technology for quality traceability; on site, 3D laser scanning is compared with BIM models to ensure component positioning accuracy with errors ≤3mm. After project delivery, supported by more than 20 after-sales maintenance centers nationwide, structural safety monitoring services are provided for up to 10 years.

IV. Industry Practice Insights: Expanding the Boundaries of GRC Applications through Technological Innovation

From the translucent concrete project at Nanjing East Road Century Plaza (winner of the AALBORG WHITE Cup UHPC Innovation Award) to the GRC curtain wall project of the Dongguan Women and Children's Activity Center, Qinglong Group has consistently led industry development through technical breakthroughs. The successful implementation of ultra-large GRC shaped element hoisting depends not only on single-point technical innovation, but also on building systematic capabilities in material performance, structural calculation, construction techniques, and project management. Looking ahead, as UHPC and GRC composite application technology matures, Qinglong will continue to explore hoisting solutions for ultra-large-span and super-high-rise scenarios, injecting more possibilities into the creation of aesthetically beautiful architecture.

As a vice-chairman unit of the China GRC Association and a participant in industry standard formulation, Qinglong Group has always upheld the philosophy of "meticulousness and excellence," providing designers and owners with expert services from concept to implementation backed by 28 years of full-chain experience. In the field of ultra-large GRC shaped element hoisting, Qinglong is not only a material supplier, but also a collaborative innovation partner that transforms architectural art into engineering reality.
