Abstract
An anchor bolt assembly for mounting within a bore formed in a rock structure, to strengthen the rock structure, comprises a shaft having a leading section and a bottom threaded section. A nut which may be attached to a face plate washer is threaded onto the end of the bottom section and bonded by an adhesive material thereto. A cartridge or capsule of anchoring cement is inserted into the bore and pierced by the leading section of the shaft as it is advanced into the bore. The shaft and nut are rotated as a unit to mix and distribute the anchoring cement within the bore and along the length of the leading section. Once the anchoring cement sets to secure the shaft in position within the bore, additional torque is applied to rotate the nut and break its adhesive bond with the bottom section. The nut is then advanced along the bottom section until the face plate washer is tightened against the rock structure.
