Abstract (en)
[origin: EP0499580A2] The extraction tool (1) for expanding sleeves (2) of anchors consists of a shank (1a) which has a conical external thread (1b) tapering towards one, free end and carries a force-application means (1c) at the other end. The shank (1a) has a central passage bore (1d), extending in the longitudinal direction, for receiving anchor bolts (4). After relieving the expanding sleeve (2) by axially driving in the anchor bolt (4), the extraction tool (1) can be screwed, by way of its external thread (1b), into the gap between the anchor bolt (4) and the expanding sleeve (2). By screwing in the extraction tool (1), the external thread (1b) cuts into the internal wall (2b) of the expanding sleeve (2) and thus forms a positive connection. By applying an axial force to the force-application means (1c), the expanding sleeve (2) can be extracted from the drill hole (9) of the receiving material (3). <IMAGE>
