1. Selection Based on Load Type
Static Loads (e.g., building columns): Ordinary pre-embedded bolts are sufficient.
Dynamic Loads (e.g., fans, machine tools): Anti-loosening design or chemical anchors are required.
High Pull-out Resistance Requirements (e.g., tower cranes): Hook-type or anchor-plate-type anchor bolts are preferred.
2. Selection Based on Foundation Material
Concrete Foundations: Pre-embedded bolts or expansion bolts.
Steel Structure Foundations: Welded or high-strength bolt connections are used.
3. Environmental Factors
Hydraulic or Corrosive Environments: Stainless steel (e.g., 304, 316) or hot-dip galvanized bolts are used.
High-Temperature Environments: Avoid using plastic expansion bolts; use metal anchors instead.
