ANCHOR BOLT, AND ADJUSTMENT MEMBER FOR ANCHOR BOLT
To provide an anchor bolt and a member for an anchor bolt which allow a joint member to be easily inserted without stress and ensures necessary strength for both shear force and axial force.SOLUTION: An anchor bolt comprises: a shaft portion to be embedded in a foundation of a structure; and a protrusion portion protruding from the foundation, and the protrusion portion is inserted into a joint member to fix it. An adjustment portion is provided at the shaft portion side of the protrusion portion and a threaded portion is provided at a tip side. A tapered portion is provided at an end of the adjustment portion at the threaded portion side. A shaft diameter of the adjustment portion is larger than a shaft diameter of the threaded portion. An axial shaft diameter of the adjustment portion protruding from the foundation is greater than a size obtained by subtracting an allowable clearance from a diameter of a bolt insertion hole provided in the joint member, and is less than a diameter of the bolt insertion hole.SELECTED DRAWING: Figure 1
【課題】 接合部材をストレスなく容易に挿入することができ、剪断力と軸力ともに必要強度を確保することができるアンカーボルト及びアンカーボルト用部材を提供する。【解決手段】 構造物の基礎に埋設される軸部と、前記基礎から突出する突出部とを備え、該突出部を接合部材に挿通して固定するアンカーボルトであって、前記突出部の前記軸部側に調整部が設けられるとともに先端側にねじ部が設けられ、前記調整部の前記ねじ部側の端部にテーパー部が設けられ、前記調整部の軸径は前記ねじ部の軸径より大きく、前記基礎から突出する前記調整部の軸方向の軸径が、前記接合部材に設けられたボルト挿通孔の直径から許容クリアランスを差し引いた寸法以上、前記ボルト挿通孔の直径未満であることを特徴とする。【選択図】図１
