Description

Anchor removal device {anchor extractor}

The present invention relates to an anchor removal device that can remove an anchor body installed on the ground, etc.

Anchors are generally used to firmly fix and install structures on walls or the ground. Once the anchor is installed on the ground, it is quite difficult to remove the anchor, and when the anchor comes out of the wall and ground on which it is installed, the wall and ground are damaged. Application No. 20-2002-0037451 In the removable anchor body, when inserting and installing the removable anchor body including the anchor head with a tapered finish formed on the rear part of the anchor head into the drilled hole, the drilled hole locally collapses. Even in this case, the re-extraction and reinsertion of the anchor body is not hindered by collapsed soil, etc., and the required bearing capacity can be secured more efficiently after the drilled hole is grouted by the anchor head formed with the tapered finish, By forming a removable locking means on the front part of the anchor head, it is possible to prevent the tension member from separating from the anchor head when transporting and installing the removable anchor body, thereby preventing deterioration in constructability due to installation and transportation of the anchor body. In the end, a removable anchor body was proposed as an anchor body, which is very advantageous in securing the required bearing capacity. However, this was because components were added to the anchor body to facilitate removal of the anchor body, and a device for actually pulling out the anchor body itself was proposed. It did not apply. As such, there has been no invention regarding a removal device for pulling out the anchor body from the ground.

In response to this, the present invention seeks to provide an anchor removal device that can easily remove the anchor body from the ground or wall using a scissor jack.
