<p>According to an embodiment of the present invention, an anchoring apparatus for introducing prestress of a stiffener is installed in a concrete structure, and is to reinforce the sagging of the concrete structure. The anchoring apparatus of the present invention comprises: a main body unit including a cylindrical-shaped anchor main body having a first insertion space, and an anchor member protruding from the outer surface of the anchor main body and coupled to the concrete structure; a rotation pipe which is installed to the anchor main body to be rotatable in the first insertion space, and has a second inversion space and screw grooves formed on the inner circumferential surface thereof; and a stiffener fixing pipe which has a structure of being inserted into the second insertion space, has a stiffener insertion hole into which the stiffener is inserted and coupled, formed therein, and screw threads formed on the outer circumferential surface thereof, and is screwed to the rotation pipe when the rotation pipe is rotated. It is desirable that the rotation shaft is installed in the main body unit and allows the stiffener fixing pipe to move along the longitudinal direction of the rotation pipe by the rotation of the rotation pipe, and applies prestress to the stiffener so as to reinforce the sagging of the concrete structure.</p> |
