Key Design Points and Critical Technology Analysis for Hoisting Plans of Large UHPC Art Shapes

Hoisting of Large-Scale UHPC Artistic Forms: A Full-Chain Technical Analysis from Design to Delivery

Against the backdrop of deep integration between contemporary architectural aesthetics and engineering technology, Ultra-High Performance Concrete (UHPC) has become the core medium of artistic expression for landmark buildings thanks to its outstanding mechanical properties and freedom of form. However, when irregular UHPC components with a 30-meter span need to be joined with millimeter-level precision in mid-air, the scientific design of the hoisting plan becomes the decisive factor for project success. As an industry-leading enterprise with 28 years of experience in detailed design and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group has built a full-process hoisting technology system covering structural analysis, equipment selection, and process control through practice on hundreds of large-scale projects.

Core Challenges and Key Design Points of UHPC Artistic Form Hoisting

UHPC artistic forms typically feature large spans, irregular curved surfaces, and thin-walled structures, and their hoisting plans must satisfy the dual demands of structural safety and artistic effect. In the Dongguan Women and Children's Activity Center project, for 12-meter-high double-curved UHPC curtain wall units, the Qinglong team innovatively adopted "3D scanning pre-assembly + modular hoisting" technology, simulating hoisting paths with BIM models to keep on-site installation errors within 3mm. The plan design stage must focus on resolving three core issues: first, optimized lifting point design based on component self-weight (typically 15-25kN/m³) and load characteristics, using finite element analysis software to determine the optimal lifting point distribution; second, matching equipment selection — choosing 25-200 ton truck cranes or tower cranes based on component dimensions (commonly 3-8m) and installation heights, together with specialized hoisting rigging; third, dynamic response to environmental factors, with contingency plans formulated for extreme conditions such as strong winds (≥ Force 6) and high temperatures.

Key Technical Breakthroughs: Coordinated Innovation from Material Properties to Construction Methods

The ultra-high strength of UHPC (compressive strength ≥150MPa) makes lightweight hoisting possible, but also imposes higher requirements on hoisting precision. Qinglong Group's self-developed "UHPC pre-embedded lifting point technology" embeds high-strength alloy lifting devices during component production to achieve uniform transfer of hoisting stress; this technology has been granted a national invention patent (Patent No.: XXXXXX). In the Nanjing East Road Century Plaza renovation project, for the hoisting of translucent UHPC components, the team innovatively applied a "vacuum suction cup + attitude fine-tuning system," successfully solving the problem of component cracking commonly caused by traditional hoisting. Notably, compared with materials such as GRC (Glass Fiber Reinforced Concrete), UHPC has a higher elastic modulus, and stress concentration during hoisting is more pronounced; therefore, structural verification under hoisting conditions must be carried out with ANSYS software to ensure a safety factor ≥1.5.

Full-Chain Management: The Qinglong Solution for Flawless Delivery of UHPC Artistic Forms

As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong Group has established a trinity project management model of "design-production-hoisting." In the detailed design stage, the Rhino+Grasshopper parametric platform is used to simulate hoisting paths; in production, automated production lines ensure component precision (±2mm); and on site, 3D laser scanning enables real-time positioning calibration. This full-chain capability allows Qinglong to undertake complex projects such as a 3000㎡ UHPC curtain wall for an international airport in Malaysia, with its overseas engineering experience testifying to the reliability of its technical system. Notably, the industry standard "General Technical Conditions for Non-Load-Bearing Ultra-High Performance Concrete (UHPC) Components" (Plan No. 2024-0232T-JC), for which Qinglong participated in drafting, is driving the standardization of hoisting technology.

From the irregular UHPC canopy of a commercial complex in Guangzhou to the openwork relief wall panels of a cultural center in Saudi Arabia, Qinglong Group's 28 years of industry experience prove that hoisting large UHPC artistic forms is not only a test of engineering technology, but also a systematic integration of materials science, structural mechanics, and project management. As the mission of "Creating Beautiful Architecture" is put into ever deeper practice, Qinglong is transforming more imaginative architectural ideas into real landmarks through continuous technological innovation. For designers and owners, choosing a UHPC manufacturer with full-chain service capability is the key guarantee for the safe realization of artistic forms.
