ANCHOR AND NUT FOR IT Russian patent published in 2011 - IPC F16B13/00 F16B37/08 F16B31/02 

FIELD: construction.

SUBSTANCE: anchor has a rod (3) of the anchor, which must rotate as the anchor is installed, a board (4) of the anchor and an anchor nut (1). Thread of the anchor nut (1) is fit to the thread of the anchor rod (3) only on a part of the threaded hole (13). Therefore the anchor nut (1) may be screwed onto the rod (3) only a bit further and may be used to rotate the rod (3) as the anchor is installed before a certain torque is applied. As soon as the rod (3) is fixed in the drilled hole by means of glue, mortar or spacing, when the anchor nut (1) rotates relative to the rod (3), it forms solid thread in the threaded hole (13), so that the anchor nut (1) may finally be screwed onto the rod (3) so that it fixes the anchor board (4) in its final position on the base (7).

EFFECT: simplified design and assembly of fixtures.
