Research on Splicing Precision Control Technology and Practice for Multi-Curved UHPC Shapes

In the field of contemporary architectural design, multi-curved UHPC forms have become key elements in shaping landmark buildings thanks to their unique artistic expressiveness and structural performance. However, their complex curved geometry and high-precision jointing requirements have long been technical challenges in the industry. As an industry leader with 28 years of full-chain experience in detailed design, manufacturing, construction and installation, and after-sales maintenance of UHPC/GRC/GRG/GRP materials, Qinglong Group has accumulated extensive technical and practical experience in jointing precision control for multi-curved UHPC forms, and is committed to providing expert solutions for designers and owners.

Jointing precision control for multi-curved UHPC forms starts with precise detailed design. Relying on the technical strength of its provincial-level R&D center and engineering technology center, Qinglong Group applies parametric design tools (such as Rhino and Grasshopper) and BIM technology to perform refined modeling of complex curved surfaces. By building three-dimensional digital models, precise control is achieved over parameters such as the dimensions, curvature, and angles of every curved unit, laying a solid foundation for subsequent manufacturing and installation. During the design process, material shrinkage characteristics and construction tolerances are fully taken into account, with reasonable adjustment allowances reserved to ensure that jointing precision meets design requirements.

Manufacturing is the core of ensuring jointing precision for multi-curved UHPC forms. Qinglong Group's production base in Nanning, Guangxi has an annual production capacity of 600,000 square meters and adopts advanced mold manufacturing technology and automated production equipment. For multi-curved UHPC forms, high-precision molds are used to ensure dimensional accuracy and surface quality. In terms of material proportioning, formulations are continuously optimized to improve the flowability and molding performance of UHPC materials, guaranteeing the compactness and dimensional stability of components. At the same time, a strict quality control system has been established to monitor every production step in real time, ensuring that the precision tolerance of components leaving the factory is kept within an extremely small range.

Jointing precision control during the construction and installation stage is equally critical. Qinglong Group holds qualifications such as Grade II contracting for building curtain wall engineering and Grade II contracting for building decoration engineering, and its construction team is highly experienced. Before construction, 3D laser scanning technology is used to accurately measure the construction site and obtain actual structural dimension data, which is then compared with the design model so that component installation positions can be adjusted in a timely manner. A modular installation process is adopted, breaking the complex multi-curved forms down into several standard modules, with precise positioning and connection achieving overall jointing precision control. During installation, dedicated measuring instruments and adjustment tools are used to monitor and adjust every joint in real time, ensuring a "zero-error" jointing result.

In addition, Qinglong Group attaches great importance to after-sales maintenance services, providing assurance for the long-term stable performance of multi-curved UHPC forms. A comprehensive after-sales maintenance system has been established, with regular project follow-ups and inspections to promptly identify and address any potential issues. Through years of practice, Qinglong Group has successfully undertaken numerous major projects featuring multi-curved UHPC forms, such as the translucent concrete project for the renovation of Century Plaza on Nanjing East Road, and its jointing precision control technology has won high recognition and praise from clients.

As a National High-Tech Enterprise and a National Specialized, Refined, Distinctive, and Innovative Enterprise, Qinglong Group consistently upholds the philosophy of professional innovation and environmental protection. Leveraging its advantages in jointing precision control technology for multi-curved UHPC forms and its full-chain service capabilities, it is committed to becoming an outstanding world-leading manufacturer of UHPC/GRC/GRG/GRP, contributing to the creation of beautiful architecture.
