Under the dual considerations of modern architectural aesthetics and structural safety, GRC curtain walls have become the preferred solution for landmark building envelope design, thanks to their lightweight, high-strength and flexible-forming characteristics. As an industry leader with 28 years of dedicated expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on its full-chain service capabilities to provide an in-depth analysis of the key connection technologies between GRC curtain walls and the main structure, delivering professional solutions for designers and owners.

Core Classification and Engineering Applications of GRC Curtain Wall Connection Systems

The connection methods between GRC curtain walls and the main structure must balance load transfer, displacement compensation and installation precision, and fall mainly into three systems: post-installed embedded connections, steel bracket connections, and precast concrete support connections. Post-installed embedments are fixed to the main structure with expansion bolts or chemical anchors and are suitable for concrete wall substrates. Qinglong adopted this solution in several commercial complex projects, combined with 3D laser positioning technology, achieving installation errors of ≤3mm. Steel bracket connections build transition frames with angle steel or square steel tubes, making them especially suitable for steel-framed structures or complex curved curtain walls. For example, in a double-curved GRC curtain wall project for a grand theater, Qinglong adopted BIM parametric design to optimize bracket spacing, effectively reducing the structure's dead weight.

Key Technical Points of Connection Node Design

Seismic performance of connection nodes is the core safeguard of GRC curtain wall safety. Following the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong's technical team reserved ≥20mm of horizontal displacement in the node design and used elastic gaskets to absorb vibration loads. For anti-corrosion treatment, all metal connectors feature dual protection of hot-dip galvanizing plus fluorocarbon spraying, combined with Qinglong's self-developed GRC-specific sealant, ensuring node durability in harsh environments such as marine climates. For oversized GRC panels (single panels up to 15㎡), an innovative "four-point elastic support" design was adopted, achieving three-dimensional fine adjustment through adjustable bolts and solving the problem of stress cracking that traditional rigid connections are prone to.

Full-Lifecycle Quality Control System

From detailed design to after-sales maintenance, Qinglong has established a quality control mechanism covering the entire process. In the design stage, finite element analysis software is used to simulate the load-bearing capacity of connection nodes, ensuring structural safety under working conditions of 1.5kPa wind load and seismic intensity 8; the production stage uses automated assembly lines to manufacture GRC panels, ensuring embedded connector position deviations of ≤2mm; during installation, a "double-inspection system" is implemented, verifying spatial positioning with a total station while performing torque testing on every node. In an airport terminal project, Qinglong achieved zero-accident delivery of 30,000㎡ of GRC curtain wall with this system, and the related technical achievements won a provincial Science and Technology Progress Award.

As a National High-Tech Enterprise and a participant in the formulation of GRC industry standards, Qinglong has always upheld the mission of "creating beautiful architecture," transforming 28 years of engineering experience into technical advantages. Whether for super high-rise landmarks or cultural venues, the connection design of GRC curtain walls requires the deep integration of material performance, structural mechanics and construction techniques. Only by choosing a supplier with full-chain service capabilities can architectural aesthetics be achieved while laying a solid foundation for structural safety. Qinglong is willing to empower project innovation with professional technology and work with partners to create exemplary buildings that combine artistic value with engineering quality.
