HOLE-IN ANCHOR, AND INSTALLATION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a hole-in anchor that may be manufactured at a low cost and enables an expansion part to be expanded by relatively small force.SOLUTION: A hole-in anchor 10 is anchored in an anchor hole 1 having a widened diameter part 4 formed at a prepared hole part 3, and includes a sleeve part 11 with an expansion part 22 on a tip side, and a bolt part 12 to be inserted into the sleeve part 11 and having a tapered part 15 for expanding the expansion part 22 at a position of the widened diameter part 4. The sleeve part 11 includes a plurality of sleeve pieces 31 divided into a plurality of parts in a circumferential direction, and a temporary fastening part 32 that temporarily fastens the plurality of sleeve pieces 31 abutted in a cylindrical form.SELECTED DRAWING: Figure 2
【課題】低コストで製造することができると共に、拡開部を比較的小さな力で拡開することができる後施工アンカー等を提供する。【解決手段】下穴部３に拡径部４形成したアンカー穴１に定着される後施工アンカー１０であって、先端側に拡開部２２を有するスリーブ部１１と、スリーブ部１１に挿通すると共に、拡開部２２を拡径部４の位置で拡開させるテーパー部１５を有するボルト部１２と、を備え、スリーブ部１１は、周方向に複数分割した複数のスリーブ片３１と、複数のスリーブ片３１を円筒状に突き合せた状態に仮止めする仮止め部３２と、を有している。【選択図】 図２
