EXPANDABLE HOLE-IN ANCHOR BOLT
PROBLEM TO BE SOLVED: To provide an anchor bolt that can be adapted for its removal from a floor after placing and fixing.SOLUTION: An anchor bolt 10 comprises a hollow bolt main body 20 and a driving pin 30. The bolt main body 20 comprises an expansion part 22 that can be expanded by slits 23 and a flange 27 with a larger diameter than that of a lower hole Sh at both ends of a residual bolt main body part 24. Thickness of the expansion part 22 is thicker than that of the residual bolt main body part 24 and has an inner diameter smaller than that of the residual bolt main body part 24. The driving pin 30 has a wedge induction part 32 realizing a wedge action while expanding the expansion part 22 at the lower hole Sh and a driving part 34 connected by a connecting part 36. The connecting part 36 has a smaller diameter than that of the wedge induction part 32 and the driving part 34 and a smaller diameter than the inner diameter of the expansion part 22 and at the same time has a longer length than that of the expansion part 22 along a longitudinal direction of the bolt main body. Thus, driving of the driving pin 30 causes the wedge induction part 32 to be pulled out of the expansion part 22 and the connecting part 36 to be stayed at the expansion part 22.
【課題】打込固定後における床からの取り除きにも対処可能な新たなアンカーボルトを提供する。【解決手段】アンカーボルト１０は、中空のボルト本体２０と、打込ピン３０とを備える。ボルト本体２０は、残余ボルト本体部２４の両端に、スリット２３により拡張可能な拡張部２２と下穴Ｓｈより大径のフランジ２７を備える。拡張部２２は、残余ボルト本体部２４より肉厚とされ、残余ボルト本体部２４より小径の内径を備える。打込ピン３０は、拡張部２２を下穴Ｓｈにおいて拡張して楔作用を発揮する楔誘起部３２と打込部３４とを連結部３６にて繋いで備える。連結部３６は、楔誘起部３２および打込部３４より小径で、且つ、拡張部２２の内径より小径であると共に、ボルト本体長手方向に沿った拡張部２２の長さより長い。よって、打込ピン３０の打込により、楔誘起部３２は拡張部２２から抜け出し、拡張部２２には連結部３６が留まる。【選択図】図５
