Hoisting Plan Design for Large UHPC Art Shapes: Key Technologies, Risk Control, and Engineering Practice Research

In the field of contemporary architectural decoration, UHPC (Ultra-High Performance Concrete) has become a key material for creating landmark buildings thanks to its outstanding mechanical properties and artistic expressiveness. As a core step in project implementation, the hoisting of large-scale UHPC artistic shapes directly affects both the architectural aesthetic presentation and construction safety. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on practical experience accumulated from hundreds of complex projects to provide the industry with professional hoisting solutions across three dimensions: technological innovation, risk management, and engineering coordination.

I. Key Technological Breakthroughs in Hoisting UHPC Artistic Shapes

Large UHPC artistic shapes typically feature irregular curved surfaces, oversized dimensions, and heavy loads, placing extremely high demands on hoisting technology. Qinglong Group introduces BIM technology and parametric modeling at the detailed design stage, using Rhino and Grasshopper software to precisely calculate component weights and optimize lifting points, ensuring uniform stress distribution during hoisting. Take the UHPC hyperbolic sunshades of a commercial complex in Nanjing as an example: a single component measures 6m×3m and weighs over 2.5 tons. The project team innovatively adopted a "modular segmentation + 3D laser positioning" technique, controlling hoisting errors within ±2mm and perfectly achieving the smooth curved surfaces envisioned in the design.

Addressing the material characteristics of UHPC, Qinglong has developed specialized hoisting connectors made of high-strength alloy with embedded node designs, achieving tensile strength above 350MPa—far exceeding the performance of traditional connectors. In the Dongguan Women and Children's Activity Center project, this technology enabled seamless high-altitude joining of GRC and UHPC composite components, winning the Silver Award of the AALBORG WHITE Cup GRC Construction Engineering Innovation Award, confirming the reliability of the technical solution.

II. Practical Application of a Full-Process Risk Control System

Risk management for hoisting projects must span the entire design, production, and construction cycle. Qinglong has established a "three-dimensional risk assessment model": at the design stage, finite element analysis simulates structural forces under extreme conditions, such as component stability under typhoon loads; during production, RFID chip traceability technology is used to manage quality coding for every UHPC component; and during construction, intelligent monitoring systems track wind speed, angles, and stress changes in real time throughout the hoisting process.

In a UHPC curtain wall project for an airport terminal, for hoisting operations at a height of 30m, the Qinglong team developed a "graded emergency response plan": when wind speeds exceed 12m/s, wind-resistant anchoring devices activate automatically, working with a hydraulic synchronized lifting system to place components smoothly. This dual mechanism of "technical prevention + management response" enabled the project to be delivered with zero safety incidents, and this experience was incorporated as a reference case in the development of the industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)".

III. Collaborative Innovation Model in Engineering Practice

As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong Group breaks away from the traditionally fragmented supply chain model by building a "design-production-construction" collaborative platform. In a municipal project in Nanning, BIM technology integrated data from the design institute, contractors, and the production base, enabling digital workflow of UHPC artistic components from drawings to finished products, shortening the production cycle by 30% and improving installation efficiency by 40%.

For the special needs of overseas projects, such as the hoisting of GRP and UHPC composite shapes for a landmark building in Malaysia, the localized team of Qinglong Malaysia Building Materials Co., Ltd. worked in coordination with the domestic technology center, adopting a "modular sea freight + rapid on-site assembly" solution to overcome challenges in cross-border transportation and installation precision. This global coordination capability has enabled Qinglong products to successfully serve multiple overseas markets, including Southeast Asia and Australia.

From technological innovation to risk management, from domestic projects to overseas undertakings, Qinglong Group interprets its mission of "Creating Beautiful Architecture" with 28 years of professional expertise. In the field of UHPC/GRC/GRG/GRP material applications, Qinglong will continue to leverage its technical advantages as a national "Specialized, Refined, Distinctive, and Innovative" enterprise, providing designers and owners with full-chain solutions from concept to implementation, and driving the architectural decoration industry toward higher precision and superior quality.
