Abstract
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. The plate initially is substantially V-shape and has the apex substantially parallel to a minor axis of the plate so that movement of the sleeve along said shaft towards the head deforms the plate from the V-shape into a substantially plainer configuration with the ends of said plate on a major axis of the plate extending laterally beyond the head. The present invention also embraces 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.
Claims10
An anchor system comprising an anchor having a shaft, a head adjacent to one end of said shaft and extending laterally of said shaft, a sleeve surrounding said shaft and extending axially thereof, a rectangular plate having a major and a minor axis, said plate having a substantially V-shape the apex of which is substantially parallel to said minor axis, said plate having a central hole through which said shaft passes and being positioned on said shaft between said head and said sleeve so that movement of said sleeve along said shaft towards said head deforms said V-shape into a substantially plainer configuration with the ends of said plate on said major axis extending laterally beyond said head and means for a moving said sleeve axially of said shaft.
A method of installing and anchor using a resin to improve the connection of the anchor to the substrate in which it is mounted comprising cutting an undercut in a bore hole between an open end and a closed end of said bore hole, mounting an anchor in the bore hole by deforming a plate into the undercut, said plate occupying a minor amount of space in said undercut and being smaller than said bore hole to permit access for resin injected from said open end to pass said plate and enter into said undercut from the side of said plate adjacent to said open end and fill said undercut and thereby surround said anchor with said resin.
