SCREW TYPE ANCHOR
To provide a screw type anchor where a shaft is not sheared when earthquake occurs and that can mount it efficiently as compared to conventional one when mounting on a skeleton.SOLUTION: A fitting hole 110 has a first hole 111 formed onto the surface of a skeleton 100 and a second hole 112 formed at the deep end part of the first hole 111 and having a smaller diameter than the first hole 111. A screw type anchor 1 screwing into the fitting hole 110 has a shaft 10. The shaft 10 has a small diameter first shaft 11 provided at a tip side and capable of being inserted into the second hole 112 and a second shaft 12 provided at a rear end side of the first shaft 11 and having a larger diameter than the first shaft 11 and capable of being inserted into the first hole 111. A male screw part 13 screwed in an inner peripheral wall of the second hole 112 is formed at the first shaft 11. The second shaft 12 has an attaching part 14 longer than a depth of the first hole 111 and capable of attaching a nut or a bolt to the portion projecting from the surface of the skeleton 100.SELECTED DRAWING: Figure 3
【課題】地震発生時に軸部が剪断されず、しかも躯体に取り付ける際には従来よりも効率的に取り付けることが可能なねじ込み式アンカーを提供する。【解決手段】躯体１００の表面に第１の孔１１１が形成され、第１の孔１１１の奥端部に第１の孔１１１よりも細径の第２の孔１１２が形成された装着孔１１０にねじ込まれるねじ込み式アンカー１は、軸部１０を有する。軸部１０は、先端側に設けられ、第２の孔１１２に挿入可能な細径の第１軸部１１と、第１軸部１１の後端側に設けられ、第１軸部１１よりも太径であり、第１の孔１１１に挿入可能な第２軸部１２とを有する。第１軸部１１には、第２の孔１１２の内周壁に食い込んだ状態にねじ込まれる雄螺子部１３が形成される。第２軸部１２は、第１の孔１１１の深さよりも長尺であり、躯体１００の表面から突出する部分にナット又はボルトを取り付け可能な取付部１４を有する。【選択図】図３
