EXTRACTION TOOL FOR EXPANSION ANCHOR, METHOD FOR OBTAINING ANCHOR JOINT IN GROUND AND USE OF EXTRACTION TOOL Russian patent published in 2022 - IPC E04H17/20 E21D21/00 

FIELD: construction.

SUBSTANCE: technical solution relates to the field of construction, utilities or agriculture and can be used for the formation of expansion anchors in the ground. The effects are achieved by an exhaust tool for creating an expansion anchor in a rectangular metal pipe with an expansion anchor formed by deformation of the anchor sections in the direction of the ground, formed by longitudinal slots made in the ribs of the part of the metal pipe buried in the ground, which is a rod, at one end of which there are protrusions protruding beyond the cross section of the rod for a length, providing a distance between diagonally opposite protrusions less than the width of the inner section of a metal pipe, and the technical results are achieved by the method for obtaining such an anchor connection in the ground, as well as the use of such an exhaust tool.

EFFECT: simplifying the formation of an anchor connection in the ground, including when using a metal pole with an expansion anchor; increasing the rate of formation of an anchor connection in the ground, including when using a metal pole with an expansion anchor; increasing the operational reliability of the expansion anchor in the ground, including when using a metal post with an expansion anchor.
