Anchor bolt (a fastener)

Anchor bolt (a fastener)

When the mechanical components are installed on the concrete foundation, the J-shaped and L-shaped ends of the bolts are embedded in the concrete.

Anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, expansion anchor bolts and bonding anchor bolts. According to different shapes, it is divided into L-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welding embedded bolts and bottom plate embedded bolts.

Application:

1. Fixed anchor bolts, also known as short anchor bolts, are poured together with the foundation to fix equipment without strong vibration and impact.

2. Movable anchor bolt, also known as long anchor bolt, is a removable anchor bolt, which is used to fix heavy machinery and equipment with strong vibration and impact.

3. Expansion anchor bolts are often used to fix static simple equipment or auxiliary equipment. The installation of expansion anchor bolts shall meet the following requirements: the distance from the bolt center to the foundation edge shall not be less than 7 times the diameter of expansion anchor bolts; The foundation strength for installing expansion anchor bolts shall not be less than 10MPa; There shall be no cracks at the drilling hole, and attention shall be paid to prevent the drill bit from colliding with the reinforcement and buried pipe in the foundation; The drilling diameter and depth shall match the expansion anchor anchor bolt.

4. Bonding anchor bolt is a kind of anchor bolt commonly used in recent years. Its method and requirements are the same as those of anchor anchor bolt. However, during bonding, pay attention to blow away the sundries in the hole and avoid moisture.
