CRIMP GRIP WITH SCREW ROD AND TENSION MATERIAL USING IT
To provide a tension material that can be tension-fixed with a simple tensioning facility by using a PC steel stranded wire whose length can be freely changed instead of a conventional rock bolt and using the same tension-fixing method as the rock bolt.SOLUTION: In a crimp grip 1 with a screw rod, a screw rod 3 having an appropriate length is fixed to one end of a crimp sleeve 10, and a counterbore 5 is formed between the crimp sleeve 10 and the screw rod 3. A tip of a PC steel stranded wire 6 of an arbitrary length is inserted into an opening of the crimp sleeve 1 with a screw rod so that the tip reaches the counterbore 5 of the crimp sleeve 10. By reducing the diameter of the crimp sleeve 10 and integrating the crimping sleeve 1 with a screw rod and the PC steel stranded wire 6, a fixing tension material of any length having a screw fixing portion on the head can be obtained. Material costs and construction costs can be saved.SELECTED DRAWING: Figure 1
【課題】従来のロックボルトに代えて長さを自由に変更できるＰＣ鋼撚り線を使用し、ロックボルトと同様な緊張定着方法によって簡易な緊張設備で緊張定着できる緊張材を提供する。【解決手段】圧着スリーブ１０の一端部に適宜長さのネジ棒３が固定してあり、圧着スリーブ１０とネジ棒３の間に座繰り５が形成してあるネジ棒付き圧着グリップ１である。任意の長さのＰＣ鋼撚り線６の先端をネジ棒付き圧着スリーブ１の開口部に挿入して先端部を圧着スリーブ１０の座繰り５にまで到達させ、圧着スリーブ１０を縮径してネジ棒付き圧着スリーブ１とＰＣ鋼撚り線６を一体化することによって頭部にネジ固定部を有する任意の長さの定着緊張材を得ることができ、材料費及び工事費の節約ができる。【選択図】図１
