In many mechanical equipment installation projects, anchor bolts are one of the indispensable accessories. Its role is to firmly connect the equipment to the foundation, so as to avoid displacement and overturning of the equipment during operation.
There are four types of anchor bolts: fixed anchor bolts, movable anchor bolts, expanded anchor bolts, and bonded anchor bolts.
1.Fixed anchor bolts, also known as short anchor bolts, are poured together with the foundation, and the bottom is made into forks, rings, hooks, etc., to prevent anchor bolts from rotating and pulling out. Suitable for equipment that does not have strong vibrations and shocks.
2.Movable anchor bolts, also known as long anchor bolts, are a kind of detachable anchor bolts, which are relatively long, or double-ended threaded double-ended type, or T-shaped head with one thread and the other T-shaped head, which is suitable for heavy equipment with strong vibration and impact. ”
3.The distance from the center of the anchor bolt to the edge of the foundation is not less than 7 times the diameter of the anchor. The strength of the foundation on which the expansion anchor is installed shall not be less than 10 MPa. It is often used for simple equipment or auxiliary equipment that is fixed and stationary.
4.Bonding anchor bolts, bonding anchor bolts is a kind of anchor bolts commonly used in recent years, and its method and requirements are the same as the expansion anchor. During bonding, the debris in the hole should be blown clean, and the anchor bolts should be anchored with epoxy resin mortar.
