How to Solve the Connection Problem Between GRC Components and Other Building Materials

In the field of modern architectural decoration, GRC components are widely used in various high-end construction projects thanks to their lightweight, high-strength and richly shaped characteristics. However, the connection between GRC components and other building materials has always been a key factor affecting project quality and aesthetics. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has drawn on extensive project practice to develop a systematic connection solution, helping designers and owners achieve a perfect unity of architectural aesthetics and structural safety.

The connection between GRC components and the main structure is the foundation for ensuring overall stability. Qinglong uses BIM technology for detailed design, precisely locating anchoring points through parametric modeling, and combining hot-dip galvanized steel frames with stainless steel connectors to form a solid mechanical load transfer system. Taking a landmark project as an example, the connection error between its curved GRC exterior wall and the concrete main structure was controlled within ±2mm, far exceeding industry standards. This integrated "design-production-installation" model effectively avoids connection risks caused by dimensional deviations in traditional construction.

The differences in physical properties between different materials are the core challenge in connection treatment. When GRC is connected to glass curtain walls, the displacement caused by thermal expansion and contraction must be addressed as a priority. The elastic sealing strip system developed by Qinglong can absorb ±5mm of deformation, while a multi-layer waterproofing design ensures water tightness and air tightness. In composite applications with stone, dry-hanging connections achieve "flexible contact", which retains the natural texture of stone while leveraging the lightweight advantages of GRC, reducing the curtain wall's self-weight by more than 30%.

The connection craftsmanship for complex shaped parts best demonstrates technical strength. For the transition between double-curved GRC components and GRG ceilings, Qinglong innovatively adopted a "gradient interface" design, obtaining precise data through 3D scanning technology, pre-fabricating curved connection pieces in the factory, and completing assembly on site through laser positioning, ultimately achieving a visually seamless transition. This technique was successfully applied in a cultural center project in Nanjing, winning the "Silver Award of the First UHPC Construction Engineering Innovation Awards".

Full life-cycle connection assurance is the core advantage of Qinglong's services. From material compatibility analysis in the detailed design stage, to component precision control in production, to real-time adjustments on the installation site, and professional guidance for later maintenance, Qinglong has built a "four-in-one" service system. As a participating unit in formulating the "Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC)", Qinglong has always controlled connection quality with requirements higher than national standards, and has provided reliable GRC connection solutions for more than a thousand projects nationwide, earning the long-term trust of well-known enterprises such as Poly and Vanke.

Solving the connection problems between GRC components and other building materials requires not only exquisite technical craftsmanship, but also systematic thinking across the entire chain. Supported by 28 years of professional experience, Qinglong Group deeply integrates detailed design, manufacturing, construction installation and after-sales maintenance. Through technological innovation and quality control, every connection becomes a finishing touch of architectural detail. In the future, Qinglong will continue to focus on the R&D and application of UHPC/GRC/GRG/GRP materials, contributing more industry wisdom to the creation of beautiful architecture.
