POST-INSTALLATION ANCHOR AND INSTALLATION METHOD THEREOF
To provide a post-installation anchor and an installation method thereof allowing an installation state of an anchor to be stabilized even in a state without attachment of attachment objects, flexibility of installation work to be enhanced, and workability to be improved.SOLUTION: A post-installation anchor 1 is provided with: a head 2 which has a male screw part 21 formed on a base end side and a cylindrical column part 23 in a generally cylindrical column shape formed on a tip side though a taper part 22 whose diameter gradually expands toward the tip and which includes an uneven shape on at least a part of an outer peripheral surface 231 of the cylindrical column part 23; an expansion sleeve 3 which has a plurality of expansion blades 32 arranged in circumferential direction with slits 31 cut from the tip to expand the expansion blades 32 such that the expansion blades 32 run on the taper part 22 toward a tip of the head 2; and a female screw body 4 which has a female screw part 41 threadably engageable with the male screw part 21 from the tip toward the base end side to hold an expansion state of the expansion blades 32 of the expansion sleeve 3 of the tip side through thread engagement between the female screw part 41 and the male screw part 21.SELECTED DRAWING: Figure 1
【課題】取付物が取り付けられていない状態でもアンカーの設置状態を安定させることができ、施工作業の自由度を高め、施工性を向上することができる。【解決手段】基端側に雄ねじ部２１が形成され、先端側に先端に向かって漸次拡径するテーパ部２２を介して略円柱状の円柱部２３が形成され、円柱部２３の外周面２３１の少なくとも一部に凹凸形状が設けられているヘッド２と、先端からスリット３１が切り込まれて拡開羽根３２が周方向に複数設けられ、ヘッド２の先端に向かって拡開羽根３２がテーパ部２２に乗り上げることにより拡開羽根３２が拡開される拡開スリーブ３と、先端から基端側に向かって雄ねじ部２１に螺合可能な雌ねじ部４１が形成され、雌ねじ部４１と雄ねじ部２１の螺着により先端側の拡開スリーブ３の拡開羽根３２の拡開状態を保持する雌ねじ体４を備えるあと施工アンカー１。【選択図】図１
