Abstract: A post-construction composite anchor bolt is provided having great resistance to a bending moment, even when the reinforcement covering margin is small, and reduces the transformation force caused by the bending moment acting on the joining point between the connecting part and the second anchor bolt, even if the size of the anchor bolt is increased. A post construction anchor bolt in the concrete frame comprising: a first anchor bolt installed projecting outside of a concrete frame; and a second anchor bolt which is eccentrically positioned to the axis of said first anchor bolt and is installed embedded in the concrete frame, and a connecting part which links said first anchor bolt and said second anchor bolt, and is installed embedded in the concrete frame together with said second anchor bolt.

Abstract: It is an object of the present invention to make it possible to install an anchor bolt while securing the pull-out strength of the anchor bolt even when the anchor bolt installation position encounters a reinforcement in concrete. An anchor bolt according to the present invention includes a first anchor bolt 2 having an embedded portion shorter than a reinforcement covering margin, a second anchor bolt 7 having an axis at a position deflected from an axis of the first anchor bolt 2, and a coupling member 5 integrally fixing the first anchor bolt 2 and the second anchor bolt 7. Further, in an installing method of an anchor bolt according to the present invention, when a first anchor hole bored at the anchor bolt installation position encounters a reinforcement, a second anchor hole is bored at a position in a direction other than the arrangement direction of the encountered reinforcement, to thereby install the anchor bolt according to the present invention.

Abstract: It is an object to prevent the occurrence of noise from a hollow of an anchor integrated liner, to facilitate the installation of the anchor integrated liner, and to fix its liner part to its anchor shaft part.
