How to Set Up Temporary Supports During GRC Panel Installation — Standards and Practical Key Points Explained

**How to Set Up Temporary Supports for GRC Panel Installation — Analysis of Standards and Practical Key Points**

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its advantages of light weight, high strength, and flexible shaping, is widely used for exterior wall cladding panels and decorative components in high-end projects such as grand theaters, commercial complexes, and landmark buildings. However, the temporary support setup during GRC panel installation directly affects construction safety and final project quality. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018) and over a thousand engineering projects to provide systematic solutions for designers and contractors, covering both regulatory requirements and practical details.

**I. Core Standard Principles for Temporary Supports of GRC Panels**

Temporary supports serve as the "safety barrier" for GRC panels from hoisting until permanent fixing, and their setup must meet three key regulatory requirements: First, the load-bearing capacity must reach at least 1.5 times the self-weight of the GRC panel, while also accounting for dynamic factors such as wind loads and construction loads, as clearly specified in GRC Decorative Products (JC/T940-2022). Second, the stiffness of the support system must ensure no plastic deformation of the panel; especially for double-curved and large-span GRC components, BIM technology should be used to simulate stress distribution and avoid cracking risks caused by unstable supports. Finally, support point locations should avoid weak areas of the GRC panel, such as openwork decorative zones or embedded bolt holes; the spacing must be strictly calculated based on panel dimensions and generally should not exceed 1.2 meters.

**II. Key Practical Steps for Temporary Support Setup**

In the standardized construction process at Qinglong Group's Nanning production base, temporary support setup follows a "three-step method": Step one is **positioning and layout**, using 3D laser scanning technology to verify installation datum lines and ensure support points precisely correspond to embedded parts in the building structure, with errors controlled within ±3mm. Step two is **support structure selection**, with customized solutions for different scenarios — adjustable steel brackets are commonly used for exterior wall cladding panels, with verticality fine-tuned via screw rods, while interior ceiling GRC components are paired with aluminum alloy truss supports, balancing lightweight design and stability. Step three is **dynamic monitoring and unloading**: after the support system is installed, 24-hour settlement observation is required, and unloading follows the "staged and symmetrical" principle to prevent panel displacement caused by excessive load on a single point.

**III. Common Problems and Expert Solutions**

In actual construction, temporary supports are prone to "over-support" or "insufficient support" problems. For example, in a commercial complex project, GRC decorative moldings became bent due to excessive support spacing; Qinglong's technical team completed the rectification within 48 hours by adding diagonal supports combined with carbon fiber reinforcement. For high-temperature or severely cold environments, elastic support joints with reserved thermal deformation allowance are recommended; in coastal areas, support components require anti-corrosion treatment to ensure durability. In addition, Qinglong's self-developed RFID quality traceability system records support installation parameters in real time, providing data support for later maintenance.

**Conclusion**

Scientific setup of temporary supports is the "invisible cornerstone" of GRC panel installation quality. As a national high-tech enterprise and a participant in formulating GRC industry standards, Qinglong Group always maintains an attitude of "meticulousness and constant improvement," deeply integrating detailed design, manufacturing, and construction installation to provide customers with full-chain services from scheme optimization to after-sales maintenance. Whether for super high-rise landmarks or complex special-shaped components, Qinglong, leveraging 28 years of technical expertise and the professional strength of an international GRC association member, ensures the safety and aesthetic realization of every project, advancing its mission of "Creating Beautiful Architecture."
