Abstract:
1. Anchor bolt assembly for anchoring an object to a retaining structure having a pre-formed receiving hole for the anchor bolt, the anchor bolt having a generally cylindrical grip end formed by a static mating portion and a movable mating portion and an actuating end remote from the grip end for effecting relative longitudinal displacement of said mating portions, the mating portions each having at least one complementary ramp surface inclined to a longitudinal axis for the anchor bolt, the static mating portion having an outer peripheral surface which is roughened for radial penetration into a receiving hole, and the moveable mating portion having a smooth outer peripheral surface, whereby operation of the actuating end will cause the movable mating portion to slide relative to the static mating portion and apply radial pressure at the grip end of the anchor bolt assembly in a loaded configuration thereof, wherein the actuating end includes a threaded portion and a cooperating nut, wherein the threaded portion is formed at an end of the movable mating portion remote from the grip end, wherein the static mating portion has a coupling ring formed at an end remote from the grip end to slidingly receive the threaded portion of the movable mating portion therethrough.
