Steel Structure Bolts

• Use type: Anchor bolts are usually used.
• Application method: During foundation construction, first reserve bolt holes or embed anchor bolts in the foundation according to design requirements. After the steel column is hoisted in place, align the bottom plate hole of the steel column with the anchor bolt, put on and put on the nut, and adjust the position of the nut to accurately adjust the elevation and verticality of the steel column. Finally, tighten the nut to firmly connect the steel column to the foundation, so that the steel column can stably bear the load of the superstructure and transfer the load to the foundation.

Use type: High-strength bolts are generally used.

Application method: At the connection between the steel column and the steel beam, the bolt hole is pre-processed on the component. During installation, insert the high-strength bolt into the bolt hole and tighten it according to the specified torque value using a special torque wrench. The pre-tension of high-strength bolts generates friction on the connection surface to transfer the internal force between the steel column and the steel beam, so that they work together to form a stable frame structure.

Use type: High-strength bolts or ordinary bolts are often used, and they are selected according to the stress conditions and design requirements.

Application method: When high-strength bolts are used for connection, similar to the connection between steel columns and steel beams, the force is transmitted by the pre-tension of the bolts and the friction of the friction surface. For some secondary structures or parts with less stress, ordinary bolts may be used for connection. During installation, insert the ordinary bolts into the holes and tighten the nuts. The reliability of the connection is mainly guaranteed by the shear and pressure resistance of the bolts.

Use type: Ordinary bolts or high-strength bolts are generally used.

Application method: The support system of steel structures includes column support, roof support, etc., which are used to enhance the overall stability and lateral force resistance of the structure. Bolts are used to connect at the connection nodes between the support and steel columns, steel beams or other components. Bolts firmly connect the support members to the main structure, so that the support can effectively transmit horizontal forces and tension, and limit the deformation of the structure.

Use type: High-strength bolts are mostly used.

Application method: The rods of the steel truss are usually connected with high-strength bolts through the node plate. During factory processing, the bolt holes are accurately processed on the rods and node plates. At the construction site, the rods are aligned with the node plates, and high-strength bolts are inserted and tightened so that the rods can work together to form a stable truss structure, withstand the loads transmitted from the roof or floor, and transfer the loads to the columns or foundations.

Use type: Generally, ordinary bolts or self-tapping screws are used.

Application method: For the enclosure structure of steel structure buildings, such as color steel plate walls and roofs, ordinary bolts or self-tapping screws are usually used to fix enclosure materials such as color steel plates to the purlins or wall beams of the steel structure. Self-tapping screws can be drilled directly into steel or plates. They are easy and quick to operate and can effectively connect the enclosure structure to the main steel structure, playing a role in windproof, waterproof, and heat preservation.
