Anchor bolts are indispensable bolt type steel structure accessories in steel structure buildings. They are mainly used to fasten steel structure building components or equipment to the concrete foundation, and play the role of fixing the foundation and connecting the main body. The following is a detailed explanation of anchor bolt steel structure accessories.
Anchor bolts are indispensable bolt type steel structure accessories in steel structure buildings. They are mainly used to fasten steel structure building components or equipment to the concrete foundation, and play the role of fixing the foundation and connecting the main body. The following is a detailed explanation of anchor bolt steel structure accessories:
Anchor bolts, also known as anchor screws, are a mechanical component that is commonly used in infrastructure such as railways, roads, electricity, bridges, boiler steel structures, tower cranes, and large buildings. It fixes equipment and steel structure facilities by pre-burying one end underground and passing the other end through the equipment and tightening it with a nut.
There are many types of anchor bolts, which can be divided into the following categories according to different classification standards:
1. Classification by function: It can be divided into fixed anchor bolts, movable anchor bolts, expansion anchor bolts and adhesive anchor bolts. Fixed anchor bolts are suitable for equipment without strong vibration and impact; movable anchor bolts are removable and suitable for large machinery and equipment with strong vibration and impact; expansion anchor bolts are used to fix simple and light equipment and auxiliary equipment in a static state; adhesive anchor bolts are used to fix small parts of simple equipment.
2. Classification by appearance: can be divided into L-type embedded bolts, 9-shaped embedded bolts, U-type embedded bolts, welded embedded bolts, etc.
Anchor bolts generally use Q235B steel and Q355B steel as raw materials. These two steels have good mechanical properties and weldability. In addition, there are low-alloy high-strength structural steel (such as 16Mn) and 40Cr steel and other materials to choose from. The specifications and standards for anchor bolts in different countries are also different, such as British, French, German, Australian, American, etc.
Bolt Type Steel Structure Accessories are generally installed using a pre-embedded pre-drilled hole and secondary grouting. The following points should be noted during installation:
1. The size of the reserved hole must meet the requirements of civil construction and equipment installation.
2. The distance between the bolt hook of the anchor bolt and the hole wall, the bottom of the hole and the foundation edge must comply with relevant regulations.
3. For equipment with large vibration, the method of directly burying the anchor bolts should be adopted, and ensure that the distance between the center line of the anchor bolt and the foundation edge meets the requirements.
4. After the installation is completed, detailed construction records should be made to provide effective technical information for future maintenance and replacement.
As an important accessory in steel structure buildings, Liweiyuan steel structure anchor bolts play an important role in fixing equipment and steel structure facilities. When selecting and using anchor bolts, the appropriate type, material and specification should be selected according to the actual situation, and the correct installation method and precautions should be followed.
Material specifications of anchor bolts
The materials of anchor bolts are mainly Q235B, Q355B and 45# steel. Q235 steel is round and is used more frequently, while Q345 (similar to Q355B) has high strength and is not as easy to make nuts as round. 45# steel is used less frequently, and the specific selection depends on customer needs.
The specifications of anchor bolts vary, mainly depending on the needs of the use scenario and the weight and size of the connected equipment. Common specifications include M6, M8, M10, M12, M16, M20, M24, M30, M36, and some L-type anchor bolts can reach M42 and M48, or even larger. Among them, M represents metric thread, and the number after M represents the outer diameter of the bolt. For example, M12 represents an anchor bolt with a diameter of 12 mm. The specifications of L-type anchor bolts generally range from M12 to M36, and the spot specifications are mainly M20 to M36.
Please note that different specifications of anchor bolts have different bearing capacity and applicable scope. Therefore, when choosing anchor bolts, be sure to determine them according to the specific use requirements and equipment specifications.
