Make a Wedge Anchor Installation Successful

A wedge anchor is one of the most dependable construction materials used by construction and industrial sites because of its specific design to fasten concrete on its place. This anchor only works for concrete and is not suitable to bricks, blocks and other tough-wearing material. They can also be tolerant to fluid and to any environment with moisture. They are generally manufactured in three basic styles: the fully threaded, the partial threaded and the full-bodied wedge anchor.

A wedge anchor is ideal for both indoor and outdoor use. Nuclear plants, dams, skyscrapers and other big edifices all use this anchor extensively. And because they affix heavy and weighty materials, it is important that the installation is proper and fit to avoid slips and unexpected malfunctions. Anchors are basically chosen for its long thread. The scientific principle applied here is that the longer the thread is, the more stable the anchor will be in holding any weight.

Among one of the most installation problem often committed is the hollow drill of the hole for the anchor. Most concrete have steel reinforcing bars (also known as rebar) at the bottom, which can serve as a hindrance for the drilling. What the installer should do is to cut out the bar or drill unto the rebar itself. But since it can make the work strenuous and longer, most workers leave out the hole not fully drilled, and the anchor is not completely imbedded. The reason anchors are much more preferred to screws and nails as attach materials is because they can be easily pulled out once a certain force or weight is casted off upon its head. But if the anchor installation itself is faulty, then accidents could happen.
So here below are the tips to always remember when installing an anchor.

Tip 1: Always drill the hole for the anchor using a carbide bit or a hammer drill. Both the dimension of the drill and the anchor should be the same to avoid a loose installation. Allow a 1/2" extra depth for the hole to allow space for debris and particles that can fall along the drilling process.

Tip 2: Before finally installing the anchor to the hole, clean off the debris and unwanted particle first that can be a hindrance when the anchor is inserted. It is important that the hole is clean especially when you are using epoxy bolts. We want to avoid incidents such as the Boston’s Big Dig project that have been the result of lax installation.

Tip 3: The strongest anchors use cast-in-place installation. But this process can be strenuous and is only used for heavy machines. For lighter materials, use wedge anchors that use a special wedging mechanism. In the installation process, remember to allow enough spacing for each wedge so the wedge will have a smooth space for pulling.

Always remember that a wedge anchor can be a dependable mechanism. But we should also always ensure that we have it properly installed and re-checked all the time.
