Concrete Anchors – How Do They Work?

Concrete fastening is a little different compared to other methods of fastening such as those concerning materials made of metal where bolts and nuts are used. You have to use concrete anchors for this particular venture and mind you, it’s so much more difficult.

Concrete Foundation Scabbling

So basically the concept of fastening two solid bases is quite different from other kinds of applications. This is a popular material that is being used in so many industries all over the world because of all the essential qualities it possesses.

AAA Concreting, one of the top national concrete contractors in the USA, have provided the following information on concrete anchors. They can be found on their website at:

Below is a step by step guide that shows how concrete anchors work:

  • A hole has to be made on the concrete
  •  A material has to be placed in the hole in order to take up the empty space
  • Material in the hole should be expanded with the use of a screw, nail or some other kind of setting tool
  • The hole has to have certain amount of volume to it in order to be ideal. This increased volume will create the necessary friction needed to hold the material against the walls interior. The holding value is obtained through this process so make sure you don’t forget it.  This is the principle in that concrete anchor production applies – one that involves the step by step process mentioned above. You don’t expect these anchors to ever be retrieved.

Wedge Anchors

Concrete anchors that are assembled to for one unit is called a wedge anchor. They are made when steel rods (which are usually made of either stainless steel or carbon) are threaded on the ends which would result in the side opposites to where this is being done becoming a tiny bit smaller in terms of diameter which somehow affects the entire diameter of the rods.

Clips are then used as an attachment to this particular end of the rods. The anchor would then be inserted in the hole of the concrete to create a thread underneath the surface of it.

It really has to be threaded as tight as it can be. There are tools which you can use to aid in this process such a wrench driven in between the clip and the stud to tighten it even more. The hole that is drilled in the wall concrete for these wedge anchors have to be the same measurement in diameter.

Sleeve Anchors

This is an anchor that is made from 4 different parts. The 4 parts are basically made of the washer, the nut, the sleeve, and the stud. The process of applying these anchors is a little bit different than the one previously discussed but then again the professionals who do them would have mastered the process regardless.

Sleeve anchors are usually inserted into the drilled hole in the concrete pretty much like how every other concrete anchors work. After being attached it will then be made to expand against the wall, locking it in place. Again, the size of the whole drilled is similar to the diameter of the anchor itself.
