PCT No. PCT/SE92/00775 Sec. 371 Date May 10, 1994 Sec. 102(e) Date May 10, 1994 PCT Filed Nov. 11, 1992 PCT Pub. No. WO93/10363 PCT Pub. Date May 27, 1993.An anchorage arrangement in the form of a socket (1) and anchor bolts (5) for anchoring scaffolds at walls or the like. The socket (1) has an inner cruciform recess (3) with conical chamfers (4) which are adapted to the form of a conical extension (7) on the anchor bolts (5). When screwing in an anchor bolt (5), the eye (6) of a bolt (5) is placed in the recess (3) of the socket (1), whereby the conical extension (7) of the bolt (5) and the chamfers (4) cooperate, partly to guide the application of the socket (1) onto the bolt (5), and partly to stabilize the bolt (5) in the socket (1) during the operation of screwing the bolt into a wall. The socket (1) is rotated by a drill after inserting an insert pin (2) on the socket in the drill chuck. The conical extension (7) may be an integrated part of the bolt (5), but is preferably threaded on the bolt (5). |
