MULTI PRESSURE-BONDING FASTENER, AND TENDON USING THE SAME
To provide a multi pressure-bonding fastener capable of performing pressure-bonding processing of PC cables comprising a plurality of un-bonded PC steel stranded wires together, and to provide a tendon using the same.SOLUTION: A pressure-bonding sleeve 4 has a substantially columnar outer shape with a center axis coincide with that of a screw rod 3, and includes a plurality of bottomed hole portions 4a into which each of end portions of a plurality of PC steel stranded wires 6 is inserted. The plurality of bottomed hole portions 4a respectively forms an insert storage portion 4d at a bottom portion 4b side and a synthetic resin coating taking-in portion 4c at an opening side, in the center axis direction. An inner diameter of the synthetic resin coating taking-in portion 4c is larger than an inner diameter of the insert storage portion 4d in the whole length in the center axis direction, or an outer periphery of a portion of the pressure-bonding sleeve 4 forming the synthetic resin coating taking-in portion 4c is smaller than an outer periphery of a portion of the pressure-bonding sleeve 4 forming the insert storage portion 4d in the whole length in the center axis direction.SELECTED DRAWING: Figure 10
【課題】 アンボンドＰＣ鋼より線を複数備えたＰＣケーブルを一つにまとめて圧着加工できるマルチ圧着固定具、及び、そのマルチ圧着固定具を用いた緊張材を提供する。【解決手段】 圧着スリーブ４は、ネジ棒３と中心軸線を共通にする概略円柱状の外形をして、複数のＰＣ鋼より線６の端部をそれぞれ挿入する複数の有底孔部４ａを有し、複数の有底孔部４ａは、それぞれ、中心軸線方向において、底部４ｂ側にインサート格納部４ｄ、及び、開口側に合成樹脂被覆取込部４ｃを形成し、合成樹脂被覆取込部４ｃの内径が、中心軸線方向の全長にわたって、インサート格納部４ｄの内径よりも大きい、又は、合成樹脂被覆取込部４ｃを形成する圧着スリーブ４の部分の外周が、中心軸線方向の全長にわたって、インサート格納部４ｄを形成する圧着スリーブ４の部分の外周よりも小さい。【選択図】 図１０
