EXPANSION BOLT AND METHOD OF ITS ATTACHMENT

摘要

The expansion dowel consists of a sleeve (1) with longitudinal slits with a peripheral groove (2) at the joint of expansion segments (6). An inner bore is partly threaded and contains a bolt (2) with an expansion cone (3), with an outer thread on its shank next to the cone. Near the groove is a shoulder (12) with a larger wall dia. than that of the internally threaded part (8). An inner sleeve (9) with an inner thread (10) is screwed onto the bolt outer thread (5).
