T/SCQA 420-2023 Assessment Standard for Quality Assurance Capability of Prefabricated Concrete Components and Supplementary Materials Manufacturers of Assembled Buildings (Connecting Components)

Scope

Scope: This standard specifies the terminology of connectors, normative reference documents, basic requirements, resource and production management, quality control of the production process, and product quality and product management. This standard applies to the evaluation of the production quality assurance capabilities of manufacturers of auxiliary materials (connectors) for prefabricated concrete components in assembly-type buildings, and is also applicable to the quality management and production process quality control of manufacturers of auxiliary materials (connectors) for prefabricated concrete components in assembly-type buildings. Main technical contents: - FRP connectors (fiber-reinforced polymer connectors): Connectors made of fiber as the reinforcing phase and thermosetting resin as the matrix phase, formed by pultrusion, used to connect the inner and outer concrete panels of prefabricated insulated walls, enabling their collaborative operation. - Stainless steel flat connectors: Flat metal connectors used to connect the inner and outer concrete panels of prefabricated insulated walls, enabling their collaborative operation. - Stainless steel pin connectors: Double-headed pin-shaped connectors made from steel rods, used to connect the inner and outer concrete panels of prefabricated insulated walls, enabling their collaborative operation.
