WHAT IS ANCHOR BOLT?

          What is an anchor bolt? These are types of steel fasteners used to connect steel structures to a concrete anchorage. The concrete serves as an anchoring foundation to fix the structure in place. The main component of the anchoring assembly is the bolt, the nut, and the embedded anchorage. For some designs such as in an L-shaped, the body is bent in 90 degrees to create an anchoring.

            There is two (2) basic type of anchoring bolts, namely the cast-in-place and the post-installed. As the name implies, cast-in-place are the one that is set in the site before concrete pouring. On the other hand, the post-installed is installed at the site after the concrete has solidified. It can be done by drilling the concrete anchoring and installing the bolt afterward.

            Furthermore, grout or cement can be used to hold the bolt in place. The chemical capsule is the new kind of cementing the anchorage on to the concrete. First, a hole is a drill into the concrete then the adhesive solid grout which looks like a toks will be inserted into the hole. The bolt will then drill into the grout to put it in place. Since the adhesive grout is dry, the steel structure can be attached faster.
