How to Set Up Temporary Supports During GRC Panel Installation: Standard Methods and Key Safety Points Explained

Temporary supports are the "invisible framework" of GRC panel installation projects; their standardized setup directly affects construction safety and the final finish quality. As an industry-leading enterprise with 28 years of deep expertise in the UHPC/GRC/GRG/GRP field, Qinglong Group, drawing on its practical experience of participating in drafting the Technical Standard for Architectural Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), presents the industry with a systematic temporary support solution for GRC panels.

Core Design Principles for Temporary Supports of GRC Panels

As glass fiber reinforced concrete products, GRC panels feature light weight and high strength, yet their loading conditions during installation are complex. Qinglong's technical team emphasizes that temporary supports must follow the "dynamic equilibrium" principle: they must bear the panel self-weight (typically 80-120kg/㎡) and construction loads, while reserving 10-15mm of displacement space for subsequent adjustments. In simulation tests at the Nanning production base, a standardized support system can keep installation deviations within ±2mm, far exceeding the industry average.

Building a Scientific Support System

Support point layout must take into account the structural characteristics of GRC panels, adopting the "four-point uniform loading method": adjustable steel brackets are installed at positions symmetric about the panel's center of gravity, with spacing controlled at 600-800mm. For irregularly shaped GRC components (such as double-curved panels), Qinglong's original BIM pre-assembly technology can simulate support loading in advance and generate precise support point diagrams through parametric design. Support materials should be Q235B grade angle steel, with double-nut fastening at the joints to ensure a clear load transfer path.

Key Safety Control Points During the Construction Phase

The temporary support system must undergo three-level acceptance inspection: team self-inspection focuses on support verticality (deviation ≤1°), project re-inspection reviews the load calculation documents, and company final inspection uses stress testing instruments to verify support stability. In a commercial complex project in Guangzhou, Qinglong's construction team innovatively adopted a "support pre-compression test," using a 72-hour test at 1.2 times the load to effectively avoid later settlement risks. In addition, support removal must strictly follow the "symmetrical unloading" principle, with daily removal not exceeding 20% of the total.

Full-Chain Service Guarantees Support Quality

As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong has established a full-process control system covering everything from support scheme design to final acceptance. Backed by an annual capacity of 600,000 square meters at its Guangxi production base, standardized production of support components can be achieved; technical teams across the country provide on-site guidance to ensure that every project's support system meets the "Qinglong standard." This full-chain advantage has enabled Qinglong to maintain a zero-accident record in GRC installation on major projects at home and abroad, including Shanghai Disneyland and King Abdullah Port in Saudi Arabia.

Although temporary supports are merely a temporary measure during construction, they reflect the professional standards of GRC installation. With the technical expertise accumulated over 28 years in the industry, Qinglong Group will continue to promote the standardized development of GRC installation techniques, providing solid technical support for designers to realize their creative visions and for owners to ensure safety, fulfilling its corporate mission of "creating beautiful architecture."
