Examples of Common Sizes and Models of Anchor Bolts
Here are some common examples of sizes and models: diameter: The diameter of anchor bolts is usually between M6-M60, and common specifications include M6, M8, M10, M12, M16, M20, M24, M30, etc. The larger the diameter, the stronger the bearing capacity of the anchor bolt. Length: The length of anchor bolts is usually between 50mm and 2000mm, with common specifications including 50mm, 100mm, 200mm, 300mm, 500mm, 800mm, 1000mm, 1200mm, 1500mm, 2000mm, etc. The longer the length, the better the stability of the anchor bolt. Thread specification: The thread specification of anchor bolts is usually related to diameter and pitch. For example, M20X2.5 represents a thread specification with a diameter of 20mm and a pitch of 2.5mm. In addition, threads are divided into two types: coarse and fine. Coarse threads have strong load-bearing capacity but are difficult to install, while fine threads are easy to install but have weak load-bearing capacity. Model: The model of the anchor bolt is usually related to its steel material, thread shape, and size. For example, the model of Q235/45 # steel material may be M6 × 30~50mm; The model of hexagonal thread may be M8 × 40~100mm; There are also different models and size ranges for pentagonal column head, ball head thread, butterfly head thread, square head thread, trapezoidal head thread, and conical head thread. Please note that the specific size and model may vary depending on engineering requirements and usage environment. Therefore, when selecting anchor bolts, it is necessary to consider the actual needs and conditions to ensure that they meet the usage requirements. In addition, when installing anchor bolts, it is necessary to follow relevant specifications and technical requirements to ensure their correct installation and fixation, in order to ensure their stability and safety.
The following precautions should be taken when using anchor bolts:
1. Accurate selection: Based on the actual needs of the project, choose appropriate specifications, materials, and strength grades of anchor bolts to ensure they can withstand the expected loads and environmental conditions.
2. Installation accuracy: During the installation process, the position, verticality, and elevation of the foundation bolts should be strictly controlled to ensure the installation accuracy of the equipment or structure.
3. Basic quality: The foundation for installing anchor bolts should have sufficient strength and stability to avoid uneven settlement of the foundation and uneven force on the anchor bolts.
4. Cleaning treatment: Before installation, ensure that the surface of the anchor bolts is clean and free of impurities such as oil stains and rust to avoid affecting the bonding force between the bolts and concrete.
5. Tightening force: When tightening the anchor bolts, they should be operated according to the specified torque or pre tightening force to avoid being too tight or too loose. Over tightening may cause bolt breakage, while over loosening may not provide sufficient fixing force.
6. Concrete pouring: When pouring concrete, it is necessary to prevent the flow of concrete from affecting the position of the anchor bolts, and at the same time, attention should be paid to avoiding collisions with the anchor bolts during the vibration process.
7. Anti corrosion treatment: For anchor bolts in a corrosive environment, effective anti-corrosion measures should be taken, such as applying anti-corrosion paint, using stainless steel materials, etc.
8. Regular inspection: During the use of equipment or structures, regularly check the tightening of anchor bolts and whether there are any looseness, rust, or other issues, and promptly carry out maintenance and treatment.
9. Construction Record: Keep a good record of the construction of anchor bolts, including selection, installation process, testing data, etc., for future traceability and maintenance.
