Abstract:
1. An installing method of an anchor bolt, comprising: boring a hole into a concrete frame having a top surface and reinforcement positioned at a reinforcement covering margin depth in the concrete below the top surface, wherein the hole extends all of the way to the reinforcement at an anchor bolt installation position in the concrete frame, boring an anchor hole for receiving an embeddable portion of the anchor bolt, the anchor hole being located at a peripheral position of a position encountering this reinforcement to a depth equal to or longer than the reinforcement covering margin; forming a groove in the concrete between said position encountering the reinforcement and said anchor hole; embedding in said anchor hole an embeddable portion of the anchor bolt, the embeddable portion having a longitudinal axis; accommodating a coupling member in said groove so that the coupling member is countersunk below or flush with the top surface of the concrete frame; and integrally coupling the embeddable portion to a fixing shaft portion of the anchor bolt through the coupling member, the fixing shaft portion protruding from the concrete and having a longitudinal axis which is arranged at said position encountering the reinforcement, thereby fixedly installing the anchor bolt, wherein the longitudinal axis of the embeddable portion is different from and parallel to the longitudinal axis of the fixing shaft portion.
