L-Shaped Anchor Bolt And 9-Shaped Anchor Bolt

Anchor bolts are connectors used to secure mechanical equipment to a concrete foundation. It is usually made of Q235 steel, but Q345B or 16Mn can also be used for added strength. The design of the anchor bolts allows them to provide a solid connection in the concrete, preventing the equipment from moving under vibration or shock.

Classification and use

Anchor bolts can be divided into the following categories according to their use and installation methods:

Fixed anchor bolt: This bolt is poured with the foundation and is used to fix the equipment without strong vibration and shock.

Movable anchor bolts: These bolts are removable and used to hold heavy machinery with strong vibration and shock.

Expansion anchor bolt: fixed in the hole by expansion force, suitable for lighter equipment.

Ground pin bolts: Use adhesive to secure the bolts. The bolts are suitable for devices that need to be removed frequently.

Installation method

Installation methods for anchor bolts include:

On-site casting: the concrete is positioned and fixed before pouring, and the foundation is firmly connected after pouring.

Reserved holes: Holes are reserved during foundation pouring, and holes are poured after the equipment is in place, installed, and levelled.

Drilling and installation: drilling holes in the foundation, using expansion bolts fixed, suitable for small equipment.

Structure and usage scenarios

Anchor bolts are usually used in infrastructure such as railways, highways, power enterprises, factories, mines, Bridges, tower cranes, long-span steel structures and large buildings. They ensure the stability and safety of the structure by transmitting tension and shear forces.

Failure conditions and design requirements

The failure condition of the anchor bolt is mainly that the pressure level should be 10 times higher than the compressive strength of concrete when it is subjected to pure tensile force. The design needs to consider the tensile capacity of the bolt, which is usually multiplied by the cross section area times the allowable stress value.
