Anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, anchor anchor bolts and adhesive anchor bolts. Among them, they are divided into: L-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded embedded bolts, and floor embedded bolts.
Installation planning of anchor bolts Loosening of anchor bolts in the foundation When the anchor bolts are tightened near, 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 in a sufficient position , Then weld two U-shaped steel bars on the bolts, and finally clean and grout the inside of the pit with water.
After the concrete has solidified to the design strength, tighten the live anchor bolts. The treatment method of the live anchor bolts is roughly the same as the dead anchor bolts, except that the anchor bolts can be pulled out for processing. If the bolt is too long, you can cut a section on the machine tool and set the thread; if the bolt is too short, it can be extended by hot forging; if the position is not consistent, use the bending method to correct it.
