Abstract
Disclosed is an anchor having a sleeve and a concentric shaft having head at one end with a rectangular plate through with the shaft interposed between the head and the adjacent end of the sleeve. A deformable plate is positioned on the shaft between the head and the sleeve so that movement of the sleeve along the shaft towards the head deforms the plate from a configuration where the plate is substantially confined to an area within the perimeter of the head into a substantially planar configuration where the perimeter of the plate extends at least partially beyond the perimeter of the head. Also disclosed is a method of fixing the anchor in a bore hole with the ends of the plate in an undercut in the bore hole and filling the bore hole with resin while venting air via a passage extending from adjacent to a closed end of the bore hole through a suitable cover.
