ICC-ES AC422
Full Name
ICC-ES AC422 – Acceptance Criteria for Semicontinuous Fiber-reinforced Grid Connectors Used in Combination with Rigid Insulation in Concrete Sandwich Panel Construction
Scope
ICC-ES AC422 establishes the acceptance criteria for evaluating semicontinuous fiber-reinforced grid connectors used in combination with rigid insulation in concrete sandwich panel construction. These connectors are crucial for ensuring the structural integrity and performance of sandwich panels, which consist of two concrete wythes separated by a layer of insulation.
The scope of AC422 includes:
- Materials: specifications for the materials used in the connectors, including the fiber-reinforced grid and any adhesives or bonding agents, ensuring their compatibility with concrete and insulation.
- Design and performance: criteria for evaluating the design and performance of the connectors under various loading conditions, including shear, tension, and combined loads.
- Testing procedures: standardized test methods for assessing the load-carrying capacity, stiffness, and other relevant properties of the connectors.
- Installation: guidelines for the proper installation of the connectors in concrete sandwich panels, ensuring proper embedment and connection to the concrete wythes.
- Durability: evaluation of the connectors’ resistance to environmental factors, such as moisture, temperature changes, and freeze-thaw cycles, to ensure their long-term performance.
By adhering to AC422, manufacturers can ensure that their semicontinuous fiber-reinforced grid connectors meet the necessary standards for safety and performance in concrete sandwich panel construction.
