An expansible plug for from-fitting anchoring in a drilled hole

摘要

Expansion dowel for anchoring in a bore with an undercut, the expansion dowel consisting of an expansion sleeve (10) having an axial bore (12, 14), tapering gradually to the front, for guiding an expansion body (26), and having, in the front section of the expansion sleeve, fins (28) formed by longitudinal slots, which fins (28) have an undercut shoulder (20) at the front end and are conically tapered on their outside, from the front in the direction of the undercut shoulder. A guide tube (30) for a set bolt (40) for driving the expansion body (26) is used for connection at the rearward end of the expansion sleeve (10), the guide tube carrying an external stop (36) and the set bolt carrying an external stop (42). …IMAGE…
