Bolts are critical for ensuring the stability and durability of steel structures. To achieve optimal performance, follow these guidelines:
1. Surface Preparation: Clean the contact surfaces thoroughly to remove rust, oil, or debris. Misaligned holes can compromise the connection, so ensure precise alignment before installation.
2. Bolt Selection: Select bolts based on the structural load requirements. High-strength bolts, such as ASTM A325 or A490, are commonly used for heavy-duty applications, while standard bolts suffice for lighter loads. The commonly used international standards are GB, JIS, ASTM, and EN.
3. Installation Process: Insert the bolt through the pre-drilled holes. Add a washer and nut, ensuring the threads are clean and lightly lubricated for high-strength bolts. This reduces friction during tightening and ensures proper tension.
4. Tightening Procedure: Use a calibrated torque wrench to tighten the nuts. For high-strength bolts, follow a two-step process: first, perform a snug-tightening to bring the members into contact, then apply the final torque in a cross-pattern to distribute the load evenly.
5. Quality Inspection: After installation, verify the bolt tension using a torque wrench or tension testing device. Replace any bolts that fail to meet the specified requirements.
By adhering to these steps, you can ensure the integrity and safety of steel connections, making bolts a reliable choice for structural applications.
