Scaffolding wall fixture attachment device - has non threaded conical eye shaft, and wider nut on dowel

摘要

A ring eye loop and dowel plug are used for fastening scaffolding frames to e.g. walls of buildings. The loop (1) has a conically widened, non-threaded shaft (1a) at its open end. The dowel (2) comprises two or more shell pieces. It is slightly shorter than the length of the shaft between the ring and the beginning of the conical widening (1b). It has a nut (4) on an external thread (3), slightly wider than the max. dia. of the shaft in this area. This permits dowel removal from the hole, and requires min. prestressing in the static zone.
