Embedded components, typically referring to metal components pre-embedded before concrete pouring, such as anchor bolts, sleeve connectors, or anchoring systems, are used to fix steel structures, membrane structures, or other external components. Their core function is to provide reliable anchoring force, ensuring that loads (such as wind pressure, self-weight, or tension) are evenly transferred to the concrete foundation. The technical principles involve several aspects:
Materials and Corrosion Protection: Embedded components are mostly made of high-strength metal materials (such as steel), and a corrosion-resistant layer is formed through hot-dip galvanizing. Hot-dip galvanizing creates a zinc-iron alloy on the surface, effectively isolating oxygen and moisture, and slowing down the corrosion process. For example, in humid or salt spray environments, this treatment can extend the corrosion protection life to decades.
Mechanical Properties: Tensile strength is a key indicator for measuring the load-bearing capacity of embedded components, usually measured in megapascals (MPa). High tensile strength ensures that embedded components are not easily deformed or broken under stress, such as during the tensioning process of membrane structures, where they need to withstand repeated loads. In standard testing, tensile strength should meet industry benchmark values (e.g., ≥XXXMPa) and be verified through tensile testing.
Precision and Design: Construction errors directly affect installation quality. Ideal embedded parts employ precision manufacturing processes, controlling errors within a small range (e.g., ≤2mm) to ensure perfect matching with steel structures or concrete. In terms of design, variable diameter connectors or reverse wire structures can adapt to different connection requirements, improving overall stability.
Certification and Reliability: Authoritative certifications (such as GB national standards or ISO international standards) guarantee the quality of embedded parts. These standards cover wind and seismic resistance testing, ensuring zero settlement under dynamic loads and avoiding structural failure due to foundation displacement. In concealed works, the reliability of embedded parts is directly related to the overall safety factor of the building.
