According to the difference in the force of the facility, the size of the equipment and the operating conditions, the selected anchor bolts are also different. The classification of anchor bolts can be roughly divided into fixed anchor bolts, movable anchor bolts, expansion anchor anchor bolts and bonded anchor bolts. According to the different shapes, it is divided into: L-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded embedded bolts, and bottom plate embedded bolts. Commonly used anchor bolts are mainly divided into embedded, snap-attached and movable anchor bolts according to their fastening methods.
1. Embedded anchor bolts
Embedded anchor bolts are poured into the concrete foundation once or twice, mainly hook type, claw type and anchor plate type. Claw type anchor bolts have good adhesion and are often used for fastening large and medium-sized equipment. The anchor plate type has the best adhesion and positioning vertical type, which is suitable for the fastening of large and heavy equipment with impact.
2. Snap-attach anchor bolts
In the process of equipment tightening, the upper body bite bolt, its vertebral head is called the expansion tube, and the strong bite force is anchored to the concrete wall, so it is also called the expandable anchor bolt. One of the more common applications.
3. Movable anchor bolts
The biggest advantage of the movable anchor bolt is that it does not need to be poured concrete during installation, and it is easy to disassemble and assemble. Usually used in mine hoists, forging equipment, etc., which have large impacts.
