Abstract
An adhesive anchor comprises a tie rod 1 having a thread casing 3, a pressure nut 5 and a pressure plate 7. The thread casing is saw tooth shaped with steep flanks 33 facing the tie rod free end and flat flanks 31 facing away from it. The turns of the thread casing are wedged between the thread body 11 of the nut and the tie rod, considerably improving the transfer of forces between the casing and the rod. The anchor is especially suitable for the securing of gallery walls in coal mines.
