Precise Positioning of Embedded Parts for Double-Curved GRC Panels: 3D Technology Leads to Zero-Deviation Installation Reference

Embedded parts are the core hub connecting double-curved GRC panels to the main structure, and their positioning accuracy directly determines the overall project quality. Leveraging 28 years of experience in GRC detailed design and construction, Qinglong Group has established a precise positioning system for double-curved GRC panel embedded parts centered on 3D digital technology, achieving zero deviation in installation benchmarks across thousands of projects at home and abroad.

Early-stage digital modeling lays the foundation for embedded part positioning. The spatial curved-surface characteristics of double-curved GRC panels require embedded part positioning to go beyond the limitations of 2D drawings. In the Dongguan Women and Children's Activity Center project, Qinglong built a full-discipline collaborative model using BIM technology, precisely matching the spatial coordinates and angle parameters of embedded parts with the curvature data of the double-curved GRC panels, while taking into account factors such as thermal deformation and structural settlement, and reserving reasonable adjustment allowances to ensure the positioning scheme is scientifically feasible.

On-site 3D laser scanning technology enables dynamic calibration. In the 120,000-square-meter bidirectional curved-twisted roof project of the Hainan International Convention and Exhibition Center, the Qinglong team used a 3D laser scanner to perform high-precision scanning of the steel structure substrate, obtained point cloud data, compared and analyzed it against the design model, and automatically identified deviation areas. By adjusting embedded part installation positions in real time, positioning errors were controlled within ±2mm, far exceeding industry standards, providing a precise benchmark for the subsequent installation of double-curved GRC panels.

Standardized installation techniques ensure positioning stability. Qinglong developed specialized positioning fixtures for double-curved GRC panel embedded parts. In the Sichuan Panzhihua Third-Front Construction Cultural Tourism project, modular fixing brackets were used to achieve rapid positioning and temporary fixing of embedded parts. At the same time, a dual-control surveying method was adopted, combining total stations and levels for cross-verification, ensuring that the elevation, axis, and verticality of embedded parts all meet design requirements and avoiding component installation difficulties caused by positioning deviations.

As a National High-Tech Enterprise, Qinglong has incorporated embedded part positioning technology into its corporate standard system, forming full-process control from design modeling, on-site scanning, and precise installation to acceptance inspection. Backed by 58 patents and extensive project practice, Qinglong can provide customized embedded part positioning solutions for various types of double-curved GRC panel projects. Choosing Qinglong means choosing professional technology to safeguard building safety and aesthetic expression, ensuring every double-curved form is precisely realized.
