摘要

The bearing anchor (1) presents a four-edged hollow profile held by a bolt (2,4,5) of locking and service legs in an anchor sleeve (3) concreted into place. The inserted end (9) of the anchor bolt (1) is formed so one part abuts the sleeve (10) and the other part of the end (9) provides space to allow the locking leg of arrester bolt (2,4,5) to be turned outwards. This locking leg (4) is held in the anchor bolt profile by position holders (6) which ensure that the locking leg when released remains within the clear profile of the anchor bolt. In the locking position the leg projects maximally outwards so the angled service leg (5) as handle indicates the locked position.
