Basic Concepts of Fastener Anchors
Fastener anchors are specialized connectors ingeniously designed to fix objects securely to concrete, masonry, or other robust substrates. These indispensable elements in construction and engineering provide exceptional stability and strength. Through innovative mechanisms like mechanical bite, friction, or chemical bonding, they withstand diverse loads, including tension and shear forces. Fastener anchors find extensive applications in areas such as building curtain walls, steel structures, mechanical equipment installation, and pipeline fixing, proving to be a cornerstone of modern construction and industrial installation.
Mechanical Anchoring Fasteners
Expansion anchor bolts: These bolts achieve a mechanical bite with the substrate through the strategic expansion of an expansion sleeve, making them ideal for dense substrates like concrete and solid bricks. Among the common types are sleeve expansion bolts and internal expansion bolts, each offering reliable and enduring stability.
Drive-in anchor bolts: Designed for simplicity and speed, these anchor bolts are expanded and fixed by a powerful knock, ensuring rapid and efficient installation.
Self-tapping anchor bolts: Featuring self-threading capabilities, these bolts can be effortlessly screwed into pre-drilled holes, providing a secure and straightforward fixation.
Concrete screws: With a unique thread design, these screws are specifically crafted to be directly screwed into concrete, forming a robust and lasting fixation.
Chemical Anchor Fasteners
Chemical anchor bolts: Crafted from a combination of chemical adhesive and metal screw, these bolts utilize chemical bonding to secure a firm hold. They are versatile across various substrates, particularly advantageous for small margins and heavy load applications.
Injection chemical anchor bolts: These bolts use a specialized syringe to inject adhesive, making them perfect for large diameter anchoring tasks.
Tube chemical anchor bolts: Featuring a glass tube filled with reactive chemicals, these bolts mix and solidify as the screw is rotated during installation, ensuring a strong and stable bond.
