Design Essentials and Key Technologies of Hoisting Schemes for Large-Scale UHPC Artistic Forms

When architectural art collides with engineering technology, the hoisting of large-scale UHPC artistic forms is not only a breakthrough of technical challenges, but also a perfect fusion of material performance and aesthetic expression.

In contemporary architectural design, Ultra-High Performance Concrete (UHPC), with its ultra-high strength, excellent durability, and exceptional formability, has become the ideal material for shaping iconic architectural artistic forms. However, the hoisting of large-scale UHPC artistic forms, as a critical process in project implementation, involves scheme design that directly affects engineering safety, construction efficiency, and the final presentation. As an industry-leading enterprise with 28 years of full-chain experience in detailed design, manufacturing, and construction installation of UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the decisive role of hoisting schemes in project success. This article systematically analyzes the design essentials and key technologies of hoisting schemes for large-scale UHPC artistic forms, providing professional reference for designers and owners.

I. Core Design Essentials of Hoisting Schemes for UHPC Artistic Forms

Large-scale UHPC artistic forms are typically characterized by complex irregular structures, heavy single-piece weights, and high installation precision requirements. Their hoisting scheme design must be based on comprehensive consideration of material properties, structural loading, and the construction environment. First, load calculation is the foundation of scheme design. It requires combining factors such as the self-weight of UHPC components, additional loads, and wind loads, and simulating stress states under different working conditions through BIM technology to ensure the scientific selection of hoisting equipment and lifting points. Qinglong Group introduces parametric modeling technology at the detailed design stage, enabling precise analysis of stress distribution in components during hoisting and avoiding cracking risks caused by excessive localized stress.

Second, hoisting path planning must balance site conditions and construction efficiency. For the complex environments of high-end buildings such as grand theaters and commercial complexes, the Qinglong team innovatively adopted the "3D scanning + path rehearsal" technology to avoid obstacles in advance and optimize hoisting sequences, ensuring that UHPC artistic components weighing several tons (such as curved curtain wall units and irregular sunshades) can safely reach their installation positions. In addition, the design of temporary fixing schemes is equally critical. Adjustable support systems need to be customized according to component shapes, working with high-precision measuring instruments to achieve millimeter-level positioning. This stage fully demonstrates the stringent requirements that UHPC materials impose on construction technology in achieving their forms.

II. Key Technological Breakthroughs in Hoisting UHPC Artistic Forms

In the practice of hoisting large-scale UHPC artistic forms, Qinglong Group has solved many industry challenges through technological innovation. First is the development of specialized hoisting tooling. Addressing the brittle characteristics of UHPC components, flexible lifting devices and multi-point balanced hoisting technology were adopted to achieve uniform stress distribution in components. This technology has been successfully applied in the light-transmitting concrete project of the Nanjing East Road Century Plaza renovation project, winning the Silver Award of the First UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup). Second is the innovative application of modular assembly technology, which decomposes super-large irregular UHPC components into standardized units. Through factory prefabrication and precise on-site assembly, risks of working at height are greatly reduced. This method helped improve construction efficiency by 40% in the GRC project of the Dongguan Women and Children's Activity Center.

Addressing the technical difficulties of coordinated installation between UHPC and other materials, the Qinglong team developed the "UHPC-Steel Structure Composite Hoisting System," which uses BIM technology to achieve virtual pre-assembly of components with the main structure, ensuring seamless connection with decorative systems such as glass curtain walls and GRG ceilings. As a participating unit in formulating the industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)," Qinglong Group has transformed 28 years of engineering experience into technical specifications. Its proposed "hoisting stability coefficient calculation method" has become an important industry reference.

From detailed design to construction implementation, the hoisting scheme of large-scale UHPC artistic forms is a system integration of material performance, structural mechanics, and engineering management. With the technical strength of a national high-tech enterprise, relying on production bases with an annual capacity of 600,000 square meters and a nationwide service network, Qinglong Group provides customers with full-chain solutions from scheme design to after-sales maintenance. Whether it is the irregular curtain walls of landmark buildings or the artistic components of cultural venues, Qinglong always upholds the philosophy of "meticulousness and excellence," promoting the innovative application of UHPC materials in architectural decoration and helping realize the corporate mission of "creating beautiful architecture." Choosing Qinglong means choosing not only high-quality UHPC products, but also professional technical assurance that stands the test of engineering practice.
