The present invention relates to a buried anchor bolt structure which is installed in a concrete foundation so as to fix and install a structure, and more specifically, to a buried anchor bolt structure for obtaining a firm fixing force in coupling the structure to the concrete foundation, reducing the deformation of an anchor bolt, and safely fixing the structure. The buried anchor bolt structure according to the present invention comprises the anchor bolt (300) and a protruding protrusion part (350), wherein the anchor bolt includes: a head part (310); a body part (320) integrally formed to be extended from the head part (310); an end part (330) extended from the body part (320) and forming a lower end; and a horizontal bending part (340) integrally bent from the end of the end part (330); and the convex protrusion part (350) formed along the external shape of the horizontal bending part (330), wherein the protruding convex part (350) allows a contact area between the anchor bolt (300) and the concrete foundation (200) to be widened and allows the resistant force of the anchor bolt (300) to increase against a deformation force, longitudinally and transversely applied through the structure (100). |
