People who don’t go to the construction site often don’t know what an anchor bolt is. In fact, anchor bolts are very useful and closely related to people’s production and life. Today, I will introduce the installation method and use of anchor bolts. If you are interested in solving the problem when bolting, let’s take a look!
XNUMX. Installation method of anchor bolts
Placing the anchor bolts perpendicular to the object is a step to correctly install the anchor bolts.Secondly, with regard to the installation of anchor bolts, it is necessary to avoid concrete irrigation, because that will fill the anchor bolts.Next, lock all loose anchor bolts to ensure that the anchor bolts are stronger and more durable.But more importantly, in the process of tightening the anchor bolts, do not use excessive force, otherwise it will cause a large amount of concrete to flow out, which will have an adverse effect.The installation of anchor bolts needs to be very careful and record the entire installation process, because this can continuously improve the installation technology of anchor bolts, and it can also provide convenient conditions for future maintenance or replacement of anchor bolts.
XNUMX. Common problems and solutions of anchor bolts
1. The height of the anchor bolts is unqualified
If the height of the anchor bolt is not suitable, we need to cut off the excess part, and then reprocess the thread.When the height of the bolt is low and the difference is less than 15mm, we can burn the bolt to red with an oxyacetylene flame, and then stretch it to meet the length.
2. Loose inside anchor bolts
When the anchor bolts are loose, the operator should knock the bolts back to their original positions and shovel the foundation holes into a shape with a large middle end and a small end, and then tighten them to ensure normal operation.
3. Center deviation of anchor bolts
When the diameter of the anchor bolt is less than 30mm and the center deviation is within 10-30mm, the bolt can be burnt red with oxyacetylene flame, then bend it with a sledgehammer, and then reinforced with welded steel plate to prevent the anchor bolt from being tightened Back to the original state again.
When the diameter of the anchor bolt is greater than 30mm and the deviation is large, the operator can cut off the bolt and weld the steel plate to the middle of the anchor bolt.At this time, if the strength of the anchor bolt is not enough, two steel plates can be welded on both sides of the bolt for reinforcement. The length of the reinforced steel plate should be 3-4 times the diameter of the anchor bolt.
