Undercut anchor for e.g. concrete, to undercut borehole during setting process, has lug lying at disk and manufactured by compression process after setting, and expanding sleeve undercutting borehole by flat cone during setting process

摘要

The anchor has an expanding sleeve (1) lying on a disk (4) by a flanged portion (3) after a setting process. A lug (2) of a bolt (5) lies at the disk, where the lug is manufactured by a compression process after setting. The expanding sleeve undercuts a borehole by a flat cone (6) during the setting process. The expanding sleeve exhibits a continuous longitudinal slot in which the lug of the bolt is guided. A flanged portion lies on the disk after the setting process. An additional slot is arranged in a non-continuous manner, and transferred to the continuous slot at around 180 degrees.
