Design Points and Key Technology Analysis of Lifting Plans for Large-Scale UHPC Artistic Forms

In the field of contemporary architectural decoration, Ultra-High Performance Concrete (UHPC) is becoming one of the core materials for shaping urban landmarks thanks to its outstanding mechanical properties and artistic expressiveness. However, the hoisting of large UHPC art forms is often the key to a project's success—it must precisely present the designer's creative vision while also ensuring construction safety and efficiency. As an industry-leading enterprise with 28 years of experience in detailed design and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze how to overcome this industry challenge based on key technical points and hands-on experience.

I. Core Challenges of UHPC Art Form Hoisting and the Design Logic of Hoisting Plans

Large UHPC art forms typically feature numerous irregular curved surfaces, heavy individual components (up to several tons), and high installation precision requirements (tolerances must be controlled at the millimeter level), which traditional hoisting techniques struggle to meet. In the light-transmitting concrete project at Century Plaza on Nanjing East Road, Qinglong Group found that the hoisting plan needed a "3D digitalization + full-process simulation" design logic: building a 1:1 model through BIM technology to simulate in advance the lifting angle, force distribution, and in-air posture of components, while optimizing hoisting point placement and reinforcement schemes based on UHPC's compressive strength of up to 150MPa. For example, in a hyperbolic UHPC curtain wall project for a grand theater, a "four-point balanced hoisting method" combined with adjustable lifting devices successfully solved the problem of micro-deformation in components caused by their own weight.

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

The high elastic modulus and low shrinkage of UHPC materials provide fundamental advantages for hoisting, but targeted technical innovation is still required. Qinglong Group's self-developed "Embedded Hoisting Point System for UHPC Components" embeds high-strength alloy lifting devices during the factory precasting stage, increasing hoisting load capacity by 40% while avoiding structural damage to components caused by on-site drilling. For installation precision control, "3D laser scanning + real-time positioning technology" reduced the traditional tolerance range from ±5mm to ±2mm. This technology was validated in the GRC/UHPC composite form project at the Dongguan Women and Children's Activity Center, ensuring the seamless splicing of 126 irregular components. In addition, to address the temporary support challenge for large-span forms, the innovative application of a "modular steel support + hydraulic synchronous lifting system" achieved fine posture adjustment and stress release during component installation.

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

As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong Group emphasizes that hoisting plans must be integrated into full project lifecycle management. In the detailed design stage, finite element analysis under hoisting conditions is conducted jointly with structural engineers to preemptively eliminate stress concentration risks; in production, automated pouring and steam curing processes ensure a 100% compliance rate for UHPC component strength; in construction, hoisting teams with over 20 years of experience are deployed, combined with a "pre-shift technical briefing + process video traceability" system, keeping the safety accident rate at zero. Notably, Qinglong's proprietary "UHPC Component Health Monitoring System" can continuously track structural stress changes after hoisting is complete, providing data support for later maintenance. This service system has received high recognition from clients in overseas projects (such as a commercial complex in Malaysia).

From the artistic curved surfaces of landmark buildings to creative sculptures in urban landscapes, breakthroughs in UHPC hoisting technology are redefining the boundaries of architectural decoration. With 58 patents and industry experience participating in drafting the "General Technical Conditions for Non-Load-Bearing Ultra-High Performance Concrete (UHPC) Components," Qinglong Group has always upheld "creating beautiful architecture" as its mission, providing designers and owners with full-process solutions from concept to realization. In the future, as UHPC materials continue to innovate in lightweighting, light transmittance, and other areas, hoisting techniques will develop toward greater intelligence and precision, and Qinglong will continue to act as a technology leader, driving the dual upgrade of industry standards and aesthetic expression.
