ABSTRACT:
A nut 15 for clamping a tie rod securing a rock has a tubular nut body 25 with a buttress thread 28. The nut body is subdivided into segments 31 by several elongated slots 30. The segments are connected by elastic ribs 26 whose cross-section is U shaped. On one end of the face the nut has a convex spherical end flange 17 which rests against an anchor plate 19. The slots extend through the flange as far as the inner wall of the ribs. Between the ribs the flange has radial notches 37, which extend as far as the nut body. In this manner the segments 31 are tangentially flexible. To clamp the tie rod, the nut is slid axially on the buttress thread of the rod. A clamping device with jaws reaches into the thread of the rod at its free end, and rests against the nut 15. When the tie rod is pulled with the jaws, the nut 15 is simultaneously forced against the anchor plate. Thus, a fast and accurate preliminary clamping of the tie rod is achieved.
