Analysis and Application of Connection Methods Between GRC Curtain Wall and Main Structure

Analysis and Application of Connection Methods Between GRC Curtain Walls and the Main Structure: Dual Assurance of Safety and Aesthetics

For GRC curtain walls, the connection method is the "lifeline" hidden behind architectural aesthetics—it not only determines the stability and durability of the curtain wall, but also directly affects the efficiency of realizing design concepts and the whole life-cycle cost. Qinglong, with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, knows that the connection stage is the core control point of GRC curtain wall projects. Today, we will provide an in-depth analysis based on hands-on experience.

I. Core Types of Connections Between GRC Curtain Walls and the Main Structure and Their Applicable Scenarios

Currently, the connections between GRC curtain walls and the main structure fall into three main categories, which need to be adapted according to building type, shape complexity, and construction conditions: embedded connections are suitable for new landmark buildings, such as a provincial convention and exhibition center project undertaken by Qinglong, where embedded parts were pre-installed into the main structure, providing super-strong load support for the large-span GRC curtain wall; post-installed embedded parts are better suited for renovation and expansion projects, requiring no damage to the original main structure and greatly shortening the construction period—Qinglong adopted this method in multiple commercial complex renovation projects, balancing efficiency and safety; steel corbel support targets extra-large irregular GRC components, such as the hyperbolic exterior walls of museums, where customized steel corbels disperse loads, ensuring structural stability while realizing the designed shapes.

II. Key Technical Points of GRC Curtain Wall Connection Methods—Qinglong's 28 Years of Practical Experience

Detail control of the connection method directly determines the success or failure of a project. First is positioning accuracy: Qinglong uses BIM technology and 3D laser scanning to control the positioning error of embedded parts within 2mm, fully meeting the requirements of the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Building (JGJ/T423-2018); second is anti-corrosion treatment: all connectors use a hot-dip galvanizing process, combined with Qinglong's self-developed anti-rust coating, to resist corrosion in extreme environments such as coastal and high-altitude areas; third is load calculation: finite element simulation software is used to simulate wind and seismic loads, customizing force-bearing solutions for each connection node, avoiding cost waste caused by over-design while eliminating safety hazards from insufficient load capacity.

III. Application Optimization of GRC Curtain Wall Connection Methods: The Value of Qinglong's Full-Chain Service

For developers, the choice of connection method must balance cost and schedule. Through in-depth design, Qinglong optimizes connection nodes in advance. In a real estate commercial project, traditional embedded parts were changed to modular post-installed embedded parts, improving construction efficiency by 30% and reducing material costs by 15%; for designers, GRC curtain walls with complex shapes need the support of connection solutions. Qinglong's parametric design team can turn creative designs such as hyperbolic surfaces and hollow-out patterns into feasible connection nodes—for example, in an art museum project, a GRC curtain wall effect without exposed keels was achieved; for the durability needs of public projects, Qinglong's after-sales maintenance service regularly inspects connection nodes for looseness and corrosion, safeguarding building safety.

The connection method of GRC curtain walls is by no means simple "fixing," but a systematic project involving materials, structure, and construction. As a national high-tech enterprise that has participated in formulating GRC industry standards, Qinglong, with 28 years of full-chain experience, can provide all kinds of clients, from real estate developers to architectural designers, with one-stop expert services covering everything from connection solution design to construction and maintenance. Choosing a professional GRC manufacturer means building a dual line of defense for the safety and aesthetics of a building.
