CUTOFF BOLT, DECORATIVE CAP MEMBER FOR SCAFFOLD TIE ANCHOR AND ASSEMBLY METHOD OF DECORATIVE CAP MEMBER FOR SCAFFOLD TIE ANCHOR
To provide a cutoff bolt allowing simple work in a simple configuration, a decorative cap member for a scaffold tie anchor and an assembly method of the decorative cap member for the scaffold tie anchor.SOLUTION: The cutoff bolt 2 according to the present invention has: a screw shaft 2a having a male screw 2 m1, 2 m2 to be fitted into a female screw 100n formed in a cylinder of a cylindrical insert 100 used at a wall tie scaffold; and a screw head 2b formed with a cap hole 2b1 having a decorative cap 3 at one end of the screw shaft 2a. The screw shaft 2a and the screw head 2b are formed integrally in resin, each screw pitch p1 of the male screw 2 m1, 2 m2 are identical with a screw pitch p1 of the female screw and two male screws 2 m1, 2 m2 are formed in the middle of each thread. A height h2 of the thread of the male screw 2 m1, 2 m2 is lower than a height h1 of the height of the thread of the female screw.SELECTED DRAWING: Figure 4
【課題】単純な構成で簡単な作業が可能な止水ボルト、足場つなぎアンカー用化粧キャップ部材及び足場つなぎアンカー用化粧キャップ部材の組み付け方法を提供する。【解決手段】本発明の止水ボルト２は、壁つなぎ足場で用いる筒状のインサート１００の筒内に形成される雌ねじ１００ｎに嵌合する雄ねじ２ｍ１、２ｍ２を有するねじ軸２ａと、ねじ軸２ａの一端部に化粧キャップ３が設けられるキャップ穴２ｂ１が形成されたねじ頭部２ｂと、を有し、ねじ軸２ａとねじ頭部２ｂとが一体に樹脂で形成されており、雄ねじ２ｍ１、２ｍ２のそれぞれのねじピッチｐ１は、雌ねじのねじピッチｐ１と同じであり、かつ、雄ねじ２ｍ１、２ｍ２がそれぞれのねじ山の中間に２つ形成されており、雄ねじ２ｍ１、２ｍ２のねじ山の高さｈ２は、前記雌ねじのねじ山の高さｈ１より低い。【選択図】図４
