Description
Product Description
A Post-Expansion Mechanical Anchor Bolt is a high-performance fastener designed for anchoring structural components to concrete, masonry, or similar rigid substrates. It consists of a threaded rod, an expansion sleeve, and a mechanical locking mechanism (e.g., wedge, cone, or undercut sleeve). During installation, the anchor is inserted into a pre-drilled hole, and torque applied to the bolt causes the sleeve or cone to expand radially, creating a mechanical interlock with the substrate. This design generates high pull-out resistance and shear strength without relying on chemical adhesives, making it suitable for immediate load-bearing applications.
Key features include:
- High Load Capacity: Optimized for static and dynamic loads, including seismic and vibration environments.
- Edge and Crack Tolerance: Minimal expansion stress during installation allows use near concrete edges or in cracked substrates.
- Corrosion Resistance: Available in stainless steel (A4-80) or hot-dipped galvanized steel for harsh environments.
- Reusable Design: Certain models allow disassembly and reinstallation, reducing material waste.
Applications
- Structural Engineering: Securing steel beams, columns, and curtain walls to concrete foundations.
- Infrastructure Projects: Anchoring guardrails, bridge components, and tunnel linings.
- Industrial Equipment: Mounting heavy machinery, pipelines, and conveyor systems.
- Retrofitting: Reinforcing existing structures with minimal substrate disruption.
- Architectural Installations: Fixing façades, glass railings, and suspended ceilings.
