Installing concrete bolts with safety and accuracy is essential for any structure that is meant to remain standing for a long time. Following the correct tips and tricks can ensure the best installation process and an adequate outcome. Here are some important aspects that should be taken into consideration when it comes to concrete bolt installation:
Firstly, always wear eye protection during the installation process to make sure that eyes are not exposed to any flying debris from drilling. It is especially important when dry concrete is being used.
The best method of installing concrete bolts is when the concrete is still in its wet state — that is, either when it is freshly cast or when it is still in the process of curing. In such a case, the best type of bolts to use are the cast-in bolts, which provide more stability to the structure. When the concrete is already in its hardened state, then it is best to use mechanical bolts or epoxy bolts.
To ensure that concrete does not dry on the threads during the installation process, cover the head and part of the shank of the bolt with a thin film of petroleum jelly. This method of installation helps make sure that the bolt will stay in place and provide the required stability to the structure.
Concrete bolt spacing is very important: The maximum distance from a corner should be 12 inches, and the gap between each bolt should be six feet. As for sheer walls, the maximum distance from the corner should be 12 inches, and the gap between bolts should be six feet.
When it comes to the minimum embedment required, most engineers recommend a minimum of seven inches. For example, if the ideal bolt to be installed is 10 inches, then it is a good idea to get a bolt that is an inch or two longer.
Lastly, when installing anchors to dry concrete, you should make sure to fill the drilled hole two-thirds of its depth with epoxy to secure the bolt. Before inserting the concrete bolt, use a brush and an air blower to clean the hole first.
Following these tips and tricks when installing concrete bolts can help ensure that the best installation process and an adequate outcome are achieved. It is also important to keep in mind the safety of yourself and other people involved in the installation process by wearing the necessary protection.
