Analysis of Key Design Points and Critical Technologies for Hoisting Plans of Large-Scale UHPC Artistic Forms

Large-Scale UHPC Artistic Form Lifting: A Full-Chain Technical Analysis from Design to Implementation

Driven by the dual forces of contemporary architectural aesthetics and engineering technology, ultra-high performance concrete (UHPC) has become a key material for the artistic expression of landmark building envelopes, thanks to its exceptional mechanical properties and design freedom. However, the lifting and installation of such UHPC components—often weighing tens of tons and featuring complex geometries—is both the ultimate test of an engineering team's technical strength and a critical factor determining project success. As an industry-leading enterprise with 28 years of experience in deepening design and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group has distilled a scientific and systematic methodology for lifting plan design through hundreds of large-scale projects, providing designers and owners with full-cycle technical support from material property analysis to construction implementation.

I. Technical Challenges of UHPC Artistic Form Lifting and Key Points of Plan Design

The ultra-high strength of UHPC (compressive strength exceeding 150MPa) and its ultra-low porosity give it inherent advantages in realizing artistic forms such as complex curved surfaces and openwork textures, but they also impose special requirements on lifting plans. In the UHPC curtain wall project for the Dongguan Women and Children's Activity Center, Qinglong's technical team identified three core issues to be addressed in lifting such components: load balance control of irregular structures, precision deviation correction during lifting, and the coordinated load-bearing mechanism with the main structure. The plan design stage requires BIM technology for 1:1 digital pre-assembly, using Rhino and Grasshopper parametric models to simulate lifting paths and proactively avoid component interference risks—a technical approach whose reliability has been validated in the translucent concrete project at Century Plaza on Nanjing East Road.

II. Key Technical Breakthroughs: From Material Properties to Construction Method Innovation

To address the lifting challenges of UHPC components, Qinglong's R&D team innovatively developed a "3D adjustable lifting node system" that enables real-time stress monitoring through smart lifting devices with embedded RFID chips. Combined with hydraulic synchronized lifting technology, lifting precision is controlled within ±2mm. In a hyperbolic UHPC canopy project for a commercial complex in Guangzhou, this technology successfully resolved the component cracking problem caused by stress concentration in traditional lifting processes. Notably, UHPC's elastic modulus is 30% higher than that of ordinary concrete, so lifting plans must account for its creep characteristics and release internal stress through staged loading—a detail listed as a key technical indicator in the "General Technical Conditions for Non-Load-Bearing Ultra-High Performance Concrete (UHPC) Components," which Qinglong helped develop.

III. Full-Chain Service Guarantee: Closed-Loop Management from Deepening Design to After-Sales Maintenance

As a national high-tech enterprise integrating deepening design, manufacturing, and construction installation, Qinglong has established a full-process quality control system covering "design-production-lifting-maintenance." At its production base in Nanning, Guangxi, intelligent production lines with an annual capacity of 600,000 square meters ensure component precision of ±0.5mm, laying the foundation for the lifting process; on-site construction teams are equipped with 3D laser scanning equipment for real-time coordinate calibration during installation; and in the after-sales phase, structural health monitoring systems track the performance of lifting nodes for up to 10 years. This full lifecycle service capability has made Qinglong a strategic partner of renowned real estate groups such as Poly and China Overseas, with its project cases now covering overseas markets including Malaysia and Australia.

As the trend toward artistic building envelopes deepens, UHPC artistic form lifting technology will face more challenges. Guided by its mission of "creating beautiful architecture," Qinglong Group continues to promote the deep integration of BIM technology with prefabricated construction, and the industry standards it helped revise—the "Technical Standard for Architectural Application of Glass Fiber Reinforced Cement (GRC)" and "UHPC Exterior Wall Panels"—are establishing scientific norms for the industry. For designers and owners seeking a balance between architectural aesthetics and engineering safety, choosing a UHPC supplier with full-chain service capabilities is the key to achieving a perfect unity of artistic vision and engineering implementation.
