Hebei anchor bolt manufacturer describes the phenomenon that anchor bolts are installed too high

1. When the bolt is too high, cut off the higher part and then cover the thread. When threading, oil should be prevented from dripping on the root of the concrete, affecting the quality of the root.

2. When the bolt is low and the error is small (15)mm inside), bake the red bolt with oxy-acetylene and then elongate it. The method of elongating is to use two stacking pads as supports, and then place a steel plate with a hole in the middle on the anchor bolt, tighten it with a nut, and stretch the bolt through the force of tightening the nut. The diameter of the bolt is stretched, and 2 to 3 steel plates are welded for reinforcement. If the device is placed on the foundation and cannot be moved easily, tighten the nuts on the base to lengthen the bolts when the strength of the seat flange is sufficient. When tightened to the appropriate length, loosen the nut to avoid excessive force after the bolt cools, fracturing the base flange.

If the bolt is too low (below its required height of 15 mm), when it cannot be stretched by heating, a deep pit can be dug around the bolt, about 100 mm from the bottom of the pit to cut the bolt, and a newly manufactured bolt can be welded. The elevation should meet the requirements, and then use round steel reinforcement. The length of reinforced round steel is generally 4 to 5 times the diameter of the bolt.

Anchor screws: also known as anchor bolts, anchor screws, embedded parts. Secure the machine and other screws to the ground. Also known as anchor bolts. Generally used in railways, highways, power enterprises, cement factories, mines, Bridges, automobiles, motorcycles, boiler steel structures, tower cranes, long-span steel structures, large buildings and so on. Strong stability.
