Title:
ANCHOR BOLT HAVING WEDGE PINS
Document Type and Number:
WIPO Patent Application WO/2017/188673
Kind Code:
A1
Abstract:
The present invention relates to an anchor bolt having wedge pins, comprising: an intermediate body part (3) formed to extend in an axial direction; a screw part (5) integrally extending from one end of the body part (3); and a head part (7) integrally extending from the other end laterally-facing the screw part (5) of the body part (3), and the anchor bolt having wedge pins further includes: a plurality of main wedge pins (11) radially protruding on the outer peripheral surface of the head part (7) such that the main wedge pins are formed to be relatively higher and longer; and a plurality of sub wedge pins (13) radially protruding on the outer peripheral surface, which is adjacent to the head part (7), of the body part (3) such that the sub wedge pins are formed to be relatively lower and shorter, wherein the main wedge pins (11) and the sub wedge pins (13) protrude while forming an edge (21) in the radial direction outwardly from each outer peripheral surface thereof and, simultaneously, one inclined surface of the edge (21) form wedge faces (23, 24) and the other inclined surfaces thereof form oblique surfaces (25, 26), so as to generate the overall fixing force of the anchor bolt by means of the main wedge pins formed at the head part, and can fill a gap, which is generated between the inner peripheral surface of an anchor hole and the outer peripheral surface of the body part, by means of the sub wedge pin so as to enable the movement of the body part, that is, shaking, to be prevented, thereby enabling the fixing force of the anchor bolt for the anchor hole to be stably maintained.
