POST-CONSTRUCTION ANCHOR, CONSTRUCTION METHOD FOR POST-CONSTRUCTION ANCHOR, AND POST-CONSTRUCTION ANCHOR SYSTEM
PROBLEM TO BE SOLVED: To provide a post-construction anchor etc. capable of making an expansion part securely and appropriately bitten into an enlarged diameter part of an anchor hole.SOLUTION: A body driving type post-construction anchor 10 to be fastened in an anchor hole 1 including an enlarged diameter part 4 formed at a predetermined depth position of a prepared hole part 3 comprises: an anchor body 11 including an expansion part 22 on the tip side; and a cone part 12 that is to be made to butt a hole bottom 3a of the anchor hole 1 and then relatively advance by driving of the anchor body 11 thereby to make the expansion part 22 expand. The cone part 12 is configured so as to be capable of regulating the expansion part 22's position from the hole bottom 3a so that at least the expansion part 22's tip is positioned in the enlarged diameter part 4 in a state in which the anchor body 11 has been driven.SELECTED DRAWING: Figure 3
【課題】拡開部をアンカー穴の拡径部に確実且つ適切に喰い込ませ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の所定の深さ位置に拡径部４を形成したアンカー穴１に定着される本体打込み式の後施工アンカー１０であって、先端側に拡開部２２を有するアンカー本体１１と、アンカー穴１の穴底３ａに突き当てられ、アンカー本体１１の打ち込みにより相対的に前進して拡開部２２を拡開させるコーン部１２と、を備え、コーン部１２は、アンカー本体１１が打ち込まれた状態で、少なくとも拡開部２２の先端部が、拡径部４内に位置するように拡開部２２の穴底３ａからの位置を規制可能に構成されている。【選択図】図３
