Anchor construction
Anchor is considered the most reliable way of fastening various elements to a concrete or wooden surface. The reliability of the fastening lies in the design of the product itself. The anchor bolt consists of a screw with a thread that is inside the cone-shaped capsule. On top of the bolt is a nut. After the fastener is placed in the pre-drilled hole, the nut is twisted, the bolt moves upwards, thereby breaking the edges of the sleeve. The liner rests against the surface of the hole and the element is held in it. It is quite difficult to extract such a design, but it is not impossible.
Methods of extracting the anchor
Before you specify the methods, it is worth recalling that extracting the anchor from the concrete wall - this task is very complex and time-consuming. It is necessary to think very carefully about the options for fastening heavyweight structures, so that you can avoid the need to remove the fasteners.
Method 1. Extraction "with meat"
For this, large cutters, a hydraulic pump or other devices are used to pull objects with great force. Concrete around the anchor can be broken using a chisel and a hammer. The hole formed after this can be sealed with cement or putty.
Method 2. Loosening of the holder
In the implementation of this method, it is first necessary to unscrew the nut, and then try to loosen the anchor bolster capsule. To do this, it is necessary to hammer the swirled bolt further into the wall to reduce its pressure on the capsule. After this, the degree of the spacer will decrease significantly. Then it will be possible to pull the anchor from the hole with the help of improvised tools. Also, you can maximally clog the sleeve into the wall and cover the hole with plaster and putty.
Method 3. Drilling the bolt and nut joint
As it became clear from the name of the method, he recommends drilling a hole in the place where the bolt and nut are connected. After that, you can remove the inner part of the anchor from the wall.
Method 4. Breakage of concrete around fastening element
The bolt is loosened, after which the concrete is broken by a hammer around the hairpin to a depth of one centimeter. Then you can remove the inner part of the anchor with the help of pliers.
Method 5. Drilling the anchor completely
If the fastening element is made of a weak metal( most often brass), then you can try to drill it completely with a drill. To do this, a full-length boring is performed right next to the clogged product. After that, it can also be removed using pliers or pliers. The resulting hole must be covered with filler or other construction mixes.
Last tip: in the end, the protruding part of the anchor can simply be cut off by the Bulgarian and all the irregularities should be filled if the same place does not need to drive nails, new anchors or conduct wiring on it.
From all of the above, it is clear that the removal of a clogged anchor - the event is very complex, but it is quite feasible. It is only necessary to be patient and ready for hard, if not short work and serious cleaning.
