Design Essentials and Key Technologies of Hoisting Plans for Large UHPC Artistic Shapes

Key Points and Key Technology Analysis of Hoisting Scheme Design for Large-Scale UHPC Artistic Forms

Driven by the dual forces of contemporary architectural aesthetics and engineering technology, ultra-high performance concrete (UHPC) has become the core medium for artistic expression in landmark buildings thanks to its outstanding mechanical properties and freedom of form. From the curved facades of grand theaters to the irregular components of commercial complexes, the hoisting and installation of UHPC artistic forms is both an engineering challenge and a concentrated display of technical strength. As an industry-leading enterprise with 28 years of experience in detailed design and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group has systematically outlined the full-process technical key points of artistic form hoisting projects based on the practice of over a thousand large-scale projects, providing designers and owners with expert-level solutions from scheme planning to safe implementation.

Preliminary Planning for UHPC Artistic Form Hoisting: From Structural Analysis to Scheme Selection

Successful hoisting projects begin with scientific preliminary planning. Given the high strength and low elastic modulus of UHPC materials, a three-dimensional parametric model must be established for force simulation, taking into account component self-weight (typically 20-35 kN/m³), form complexity (e.g., hyperbolic curvature radius ≤300mm), and installation precision requirements (errors must be controlled within ±2mm). Qinglong Group employs BIM technology and finite element analysis software to simulate hoisting conditions for hollowed-out UHPC components in award-winning projects such as the Dongguan Women and Children's Activity Center, focusing on verifying lifting point arrangement (each lifting point must have a load capacity ≥1.5 times the component weight), rigging selection (high-strength fiber slings preferred), and the stability of the temporary support system. For super-large components exceeding 10 meters, an innovative "modular segmentation + aerial assembly" scheme is adopted. For example, in the Century Plaza renovation project on Nanjing East Road, a 25-meter-long translucent UHPC facade was divided into 6 unit modules, achieving millimeter-level joints through precise positioning.

Key Technology Breakthroughs: Full-Chain Control from Factory Prefabrication to On-Site Installation

The hoisting quality of UHPC artistic forms depends on full-chain technical control. During the factory prefabrication stage, Qinglong Group ensures the dimensional precision of components through patented mold technology (holding 58 related patents) and achieves quality traceability with embedded RFID chips; during transportation, customized hydraulic support vehicles are used, with multi-point synchronous leveling systems keeping component tilt ≤1°. During on-site installation, specialized technologies are innovatively applied for different scenarios: for high-altitude irregular components, "3D laser scanning + unattended hoisting" technology is adopted, as in the installation of a GRP skylight roof at an international airport terminal, achieving a positioning error of ≤1.5mm for components at a height of 30 meters; for overweight components, a "hydraulic synchronous lifting system" was developed, successfully hoisting an 80-ton UHPC sculpture in a landmark project in Malaysia. Notably, the "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components" (Plan No. 2024-0232T-JC), which Qinglong participated in formulating, explicitly stipulates the safety factors and quality standards for hoisting construction, providing technical specifications for the industry.

Risk Prevention and Quality Assurance: Building a Full-Cycle Safety System

Risk prevention for artistic form hoisting runs through the entire construction cycle. Qinglong Group has established a "three-level safety review" mechanism: the technical department reviews the feasibility of hoisting schemes, the supervision team checks the calibration reports of rigging, cranes, and other equipment, and on-site engineers carry out dynamic monitoring of the hoisting process. To address environmental factors such as typhoons and temperature differences, an "intelligent early-warning system" has been developed, using sensors to monitor component stress changes in real time (warning threshold ≤80% of the design value) and crane verticality deviation. In the after-sales maintenance stage, supported by a nationwide service network, value-added services such as regular inspection of component connection joints and structural adhesive aging assessment are provided, such as the five-year maintenance plan for UHPC facades implemented for a commercial complex project, effectively safeguarding the long-term safety and aesthetics of artistic forms.

As a national high-tech enterprise and a member of the International GRC Association, Qinglong Group has always taken "creating beautiful architecture" as its mission, transforming 28 years of full-chain experience into a driving force for technological innovation. From the systematic application of UHPC to GRC/GRG/GRP materials, and from integrated services covering detailed design to hoisting construction, Qinglong is providing reliable technical support for the artistic expression of landmark buildings worldwide with a professional attitude of "meticulousness and the pursuit of excellence," committed to becoming a world-class leading manufacturer of decorative building materials.
