Essentially, a wedge anchor is used to fasten fixtures into the concrete and to create a solid point of attachment between them. The wedge anchors are inserted into a drilled hole and then stretched, causing them to lock properly into the concrete. Wedge anchors are available in different forms like zinc plate steel, hot-dipped galvanized and stainless steel. To remove your pre-installed wedge, follow the simple instructions mentioned below.
Step 1 – Take Appropriate Precautions
It is important to keep safety in mind when working with any sort of anchoring projects. Wear safety goggles and gloves to protect your skin and eyes as well. Also, handle all tools with great care to avoid injuries and hazards.
Before you begin the work, thoroughly read through the safety and precautionary manuals that accompany the power grinder etc. You must follow all technical specifications to accomplish your task properly, safely and accurately. Also, you should work in a well-lit and thoroughly ventilated area.
Step 2 – Remove the Anchor Plate
Put the edge of your pry bar against the anchor plate, and strike your hammer against the back of pry bar to push it under. Hold your tool properly for your safety and for better implementation of force on the pry plate. Apply as much force as much as you can on the anchor plate. You must use pliers to get a good grip on the plate.
Step 3 – Drill Holes on Plate
If the anchor plate is not coming off and seems stuck, use a drill machine. It’s more convenient to use an electric hand drill. Drill some holes on the anchor plate rather than in the sides. After drilling holes on the plate, use your hammers and chisel to break it.
Step 4 – Remove the Bolt and Finish Up
When the plate is removed and the bolt is exposed, use your grinder to cut it off and grind it down. You can also pull out the bolt by applying enough force, with the help of pliers. It’s better to pull out the wedge anchor using the pliers than to grind it. Pulling out the bolt will leave a hole in the concrete. The grinding of the bolt will also damage the concrete.
Fill the damaged plate with cement or gap fillers like plaster of Paris to complete the task.
