POST-CONSTRUCTION ANCHOR AND INSTALLATION METHOD OF INSTALLATION OBJECT
PROBLEM TO BE SOLVED: To provide a post-construction anchor capable of preventing looseness of a screw and preventing slipping-out of a bolt at low cost.SOLUTION: A post-construction anchor 1 is constituted of an interior body 2 having a female screw part 21 extending in the axial direction and an expansive opening member 3 for internally facing the interior body 2 from the tip side and expansively opening in the radial direction by relative press-in of the interior body 2, in which the female screw part 21 is formed up to a tip part 22 of the interior body 2, and a screw groove of the female screw part 21 corresponding to the tip part 22 is deformably formed, and suitably, a caulking part 23 of a crushed shape is formed in a predetermined place of the outer periphery of the tip part 22 so as to deform the screw groove of the tip part 22.SELECTED DRAWING: Figure 3
【課題】低コストでねじの緩み止め、ボルトの抜け出しを防止することができるあと施工アンカーを提供する。【解決手段】軸方向に延びる雌ねじ部２１を有する内装体２と、内装体２が先端側から内装され、内装体２の相対的な圧入によって径方向に拡開する拡開部材３とから構成され、雌ねじ部２１が内装体２の先端部２２まで形成され、先端部２２に対応する雌ねじ部２１のねじ溝が変形して形成されているあと施工アンカー１であり、好適には先端部２２のねじ溝が変形するようにして先端部２２の外周の所定箇所に押し潰した形状のカシメ部２３を形成する。【選択図】図３
