Document Type and Number:
WIPO Patent Application WO/2011/020696
Kind Code:
A3
Abstract:
The invention relates to a coupling (1) for connecting anchor rods (2) having external threads (4) for injection bore anchors, wherein the coupling (1) comprises a sleeve-like coupling fitting (5) having screw-in openings extending from the two opposite sides (7), each having internal threads (8), for screwing in anchor rods (2), wherein an assembly lug (10) facing radially inward is implemented between the two internal threads (8) of the screw-in openings on the inner side of the coupling fitting (5). According to the invention, in order to advantageously further develop such a coupling, the coupling (1) comprises a ring (11) for loss-proof assembly on the assembly lug (10) of the coupling fitting (5). The ring (11) comprises in particular a conical or convex curved chamfer face at both end faces thereof, and in particular comprises a side face radially internally adjacent to each chamfer face and extending at a radius interval perpendicular or at least substantially perpendicular to the geometric centerline, or wherein the ring (11) comprises one overall convex curved end face at each of the two end faces thereof. The invention further relates to an arrangement, in particular an injection bore anchor, comprising at least one such coupling (1). The invention further relates to a method for assembling an arrangement comprising at least one such coupling.
