Anchor bolts which are inserted into the hole of any component and comprising a pulling bolt having a threaded segment and a following truncated head part are well known and have proven their practical usefulness. Existing anchor bolts should be improved in such a way that a higher load bearing capacity is obtained while reducing the initial force required to insert the anchor bolt. According to the invention, the middle area of every second side of the polygon is provided with a predetermined break-off line. The sides lying in-between exhibit a solid lining from one crest limit to another. In order to produce a corner connection, profiled strips are assembled to a frame by nonpositive screwing of the anchor bolts. |
