HOLE-IN ANCHOR AND INSTALLATION STRUCTURE THEREOF, AND REMOVAL METHOD FOR HOLE-IN ANCHOR
To provide a hole-in anchor that has high anchoring force, can be prevented from coming out of concrete, can be easily removed when not necessary any more, and provides hot-dip plating in high safety.SOLUTION: A hole-in anchor 1 comprises: an inner member 2 which is provided, on a tip side of a base part 21, with a tapered part 22 gradually increasing in diameter toward the tip; and a sleeve 3 which has an expansion piece 33, expanding as the tapered part 22 enters, provided on a tip side and also has a female screw 34 formed on a rear end side. The inner member 2 is provided with a female screw hole 24 which is open on a rear end surface 23, a fitting bolt 4 can be threadedly engaged with the female screw hole 24, and a small-diameter hole 25 is formed to have a smaller diameter than the female screw hole 24 to penetrate a front end surface 26 of the inner member 2 continuously to the female screw hole 24.SELECTED DRAWING: Figure 1
【課題】高い定着力を有し、コンクリートからの抜け出しを防止できると共に、不要時に容易に撤去することができ、更に高い安全性で溶融メッキを行うことができるあと施工アンカーを提供する。【解決手段】基部２１の先端側に先端に向かって漸次拡径するテーパ部２２が設けられているインナー部材２と、先端側にテーパ部２２の入り込みで拡張する拡張片３３が設けられ、後端側に雌ねじ３４が形成されているスリーブ３を備え、インナー部材２に後端面２３で開口する雌ねじ穴２４が設けられ、雌ねじ穴２４に取付ボルト４を螺合可能であると共に、雌ねじ穴２４より小径で形成され、雌ねじ穴２４と連続してインナー部材２の先端面２６に貫通する小径穴２５が設けられているあと施工アンカー１。【選択図】図１
