CONSTRUCTION METHOD OF POST CONSTRUCTION ANCHOR

PROBLEM TO BE SOLVED: To provide a construction method of a post construction anchor for filling a filler for preventing the rust and run-out of the anchor without a risk of leaking out of an anchor hole when forming the anchor hole in the lateral direction (the horizontal direction) and the upward vertical direction. SOLUTION: In this construction method of the additional construction anchor, a diametrally expansive part is formed by diametrally expansively cutting a hole wall in the anchor hole formed in an existing concrete structure; anchor hardware is inserted into this anchor hole; a diametrally expansive metal fitting of the anchor hardware is pushed in and expanded by a tool; this metal fitting is engaged with the diametrally expansive part of the hole wall: and the filler is filled in a clearance between the anchor hardware and the anchor hole. Resin having a small contraction quantity and superior in filling performance to narrow the clearance is precedently filled in the tip of the anchor hole 2 as the filler 11 to the anchor hole, and after inserting the anchor hardware, a nonshrink filler is filled in a clearance between a screw bar and the anchor hole.
