There are other bolts used after concrete is set, namely, epoxy and mechanical bolts. Epoxy bolts are stronger than mechanical bolts but are the most difficult to install. This is due to fact that epoxy has to be mixed in the specified ratio, the hole must be very clean, and time required for setting is to be monitored. It is a very demanding and time-taking process. A concrete screw is another type of anchor bolt.
Huge anchor bolts, in highway projects, are used to bear steel beams, trusses, girders and hefty road signs. These anchor bolts are used to anchor these elements and support them against strong winds. Endurance limit of the bolts is considerably lesser than manufactured strength.
Bulky anchor bolts are also used to keep down power transmission towers and in radio tower reaction blocks.
The nuclear energy industry utilizes steel anchor bolts in several ways. It used to hold the reactors and fix them to the bases.
Large anchor bolts known as “tie-downs”, are used to hold down huge water storage tanks. They are used to handle wind loads.
Anchor bolts that are used in mining are known as rock anchors. A part of the anchor is attached to rock or concrete by cement grout, resin, or fixed by a mechanical anchor. The upper part of its length is left un-attached, but is fixed later to provide resistance against corrosion. Anchor bolts are used in retaining walls, tunnels, mines, stabilizing slopes, and provide protection from rock fall.
Some types of anchor bolts can be pre-installed and hence are easy to use. All one has to do is fix it into the hole and the one by one affix the remaining pieces.
There are several types of anchor bolts and are used extensively in different projects. As they are available in different sizes as well as heavy and light duty they have a wide range of uses. There is an anchor bolt for every type of requirement.Easy to Use
