Anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, expansion anchor anchor bolts and adhesive 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.
Anchor bolt installation planning. Treatment of loosening of anchor bolts in the foundation. When the anchor bolts are tightened, the bolts may be pulled out. At this time, the bolts should be adjusted to the original position and the foundation around the bolts should be shoveled out enough. And then weld two U-shaped steel bars in the vertical and horizontal directions on the bolts, and finally clean the pit with water and grouting.
After the concrete has solidified to the design strength, tighten the live anchor bolt deviation. The treatment method for the deviation of the live anchor bolt is roughly the same as that of the dead anchor bolt, except that the anchor bolt can be pulled out for processing. If the bolt is too long, it can be cut off on the machine tool and threaded; if the bolt is too short, it can be extended by hot forging; if the position does not match, use the bending method to correct it.
