INDICATOR-NUT THREADED COUPLING WITH LOAD-INDICATING DEVICE ADAPTED TO BE ARRANGED ON ANCHORS, IN PARTICULAR GROUTED ANCHORS FOR MINING OR THE LIKE

摘要

The invention relates to an indicating-nut threaded coupling with load-indicating device (1) adapted to be arranged in particular on grouted anchors for mining or the like and in order to obtain a simple solution which is advantageous in use it proposes that a free space be formed by at least one groove (4) equipped with a fold bottom (5), the groove being arranged in the outer wall (3) of a bushing (2) which extends at a distance from the outer surface of the anchor.
