Design Key Points and Key Technology Research of Hoisting Scheme for Large-Scale UHPC Artistic Shapes

Carving Art with Technology, Defining Safety with Craftsmanship — Breakthroughs and Practice in UHPC Artistic Form Lifting Engineering

Driven by the dual forces of contemporary architectural aesthetics and engineering technology, ultra-high performance concrete (UHPC) has become the material of choice for shaping the artistic forms of landmark buildings, thanks to its ultra-high strength, excellent toughness and outstanding plasticity. However, the precise lifting of irregular structures, as the "last mile" of project implementation, is both a technical difficulty and a quality control point. Qinglong Group, with 28 years of experience in detailed design and construction of UHPC/GRC/GRG/GRP materials, has developed a lifting solution that integrates structural mechanics, intelligent monitoring and artistic precision through the practice of hundreds of large-scale projects, setting a technical benchmark for the industry.

I. Core Challenges of UHPC Artistic Form Lifting and Solution Design Logic

Unlike traditional concrete components, UHPC artistic forms often feature complex characteristics such as large cantilevers, double-curved surfaces and openwork textures, and their lifting must balance structural safety with artistic integrity. At the solution design stage, the Qinglong team established a full-process system of "3D modeling – mechanical simulation – path optimization": through parametric modeling with Rhino and Grasshopper, design drawings are converted into constructible digital models; ANSYS is used to simulate stresses under lifting conditions, with focus on verifying the rationality of lifting point settings (usually embedded UHPC-specific lifting devices with tensile strength ≥500MPa) and component posture; a BIM visualized lifting path is developed in combination with site conditions to avoid interference from surrounding buildings and pipelines, ensuring millimeter-level installation accuracy.

II. Key Technological Breakthroughs: Full-Chain Innovation from Material Properties to Intelligent Construction

In response to the material properties of UHPC, the Qinglong R&D team has innovatively applied a number of key technologies: RFID chips are embedded at the component production stage to achieve full lifecycle traceability, and the "steel mold + vacuum casting" process is adopted during prefabrication to ensure surface flatness error ≤2mm; the lifting equipment uses a hydraulic synchronous lifting system with attitude sensors to monitor component inclination in real time (controlled within ±0.5°) and rigging tension; for super-large components (unit weight exceeding 20 tons), the innovative "temporary steel support + staged unloading" method is adopted, combined with 3D laser scanning for installation coordinate calibration, successfully solving the lifting challenge of the 36-meter cantilevered UHPC decorative wing panels at a cultural center in Nanjing.

III. Engineering Practice and Industry Value: Qinglong's Differentiated Advantages in Full-Chain Service

As a national high-tech enterprise and a participant in the formulation of UHPC industry standards, Qinglong Group deeply integrates its full-chain advantages in detailed design, manufacturing and construction installation into lifting solutions. In the Dongguan Women and Children's Activity Center project, through the integrated collaboration of "design – production – lifting", the installation error of 126 irregular UHPC curtain wall panels was controlled within 3mm, winning the AALBORG WHITE Cup GRC Construction Engineering Innovation Award; in a commercial complex project in Saudi Arabia, dedicated lifting fixtures were developed for high-temperature environments, achieving the efficient installation of 1,800 UHPC artistic components and demonstrating the international competitiveness of Chinese intelligent manufacturing.

From technical solution design to project implementation, the lifting engineering of UHPC artistic forms is both an ultimate test of material performance and a comprehensive examination of a company's overall strength. Based on 28 years of professional accumulation, Qinglong Group continues to drive innovative breakthroughs in UHPC lifting technology, not only providing designers with unlimited possibilities to realize their creativity, but also contributing the "Qinglong Solution" to the safe aesthetics of the construction industry. In the future, with the deep integration of technologies such as BIM and digital twins, UHPC artistic form lifting techniques will reach new heights of intelligence and precision.
