ANCHORING DEVICE FOR STRUCTURAL MEMBER REINFORCING TENSILE MATERIAL AND ITS STRUCTURE

PROBLEM TO BE SOLVED: To provide an anchoring device for a structural member reinforcing tensile material, applicable to a steel member without the need for forming a cutout in a concrete member while keeping a tensile material with its intermediate excluding both ends in close contact with the surface of the concrete member when introducing pre-stress in the structural member such as the concrete member or the steel member to be reinforced, and to provide its structure. SOLUTION: The anchoring device 2 comprises both-side fixed devices 3, 3 fixed to the surface of the structural member 1, to which the end of the tensile material is anchored, and an anchoring rod 4 through which an anchor 8 at the end of the tensile material 7 and the fixed device 3 are inserted in the direction of the tension of the tensile material 7 and which is connected to the anchor 8. A center side deflecting tool 5 which contacts the tensile material 7 on the back side for inclining the section of the tensile material 7 up to the fixed device 3 to the surface of the structural member 1 is fixed to the surface of the structural member 1 near the center of at least the tensile material 7. Besides, an end side deflecting tool 6 which contacts the tensile material 7 on the surface side is fixed to the surface of the structural member 1 between the center side deflecting tool 5 and the fixed device 3.
