【産業上の利用分野】本考案はコンクリートの補強筋と
して使用する熱硬化性繊維強化プラスチックロープに関
するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermosetting fiber reinforced plastic rope used as a reinforcing bar for concrete.
【０００２】[0002]
【従来の技術】従来コンクリートの補強筋としては専ら
鉄筋が使用されてきたが、近年高強度繊維の繊維束に熱
硬化性樹脂を含浸させた熱硬化性繊維強化プラスチック
（以下ＦＲＰという）ロープの使用が研究され、特に高
強度繊維として炭素繊維を用いた熱硬化性炭素繊維強化
プラスチック（以下ＣＦＲＰという）ロープは現場硬化
が可能であることから注目されている。2. Description of the Related Art As Reinforcement of conventional concrete have been used exclusively rebar, but recent high strength fiber in the fiber bundle a thermosetting resin a thermosetting fiber-reinforced plastic impregnated (hereinafter referred FRP) of the rope Use is studied, especially high
A thermosetting carbon fiber reinforced plastic (hereinafter, referred to as CFRP) rope using carbon fiber as a strength fiber has attracted attention because it can be cured in place.

【考案が解決しようとする課題】ＦＲＰロープのコンク
リートとの付着強度は一般に異形鉄筋より小さいので、
ＦＲＰロープをコンクリートとの補強筋として使用する
際には異形鉄筋に比して長い定着長が必要である。本考
案は、この定着長を異形鉄筋なみ以下に短くしようとす
るものである。[Problems to be solved by the invention] Since the bonding strength of the FRP rope to concrete is generally smaller than that of deformed reinforcing steel,
When an FRP rope is used as a reinforcing bar for concrete, a longer anchoring length is required as compared with a deformed reinforcing bar. In the present invention, this fixing length is to be shortened below that of deformed reinforcing bars.
【０００４】[0004]
【課題を解決するための手段】本考案は、ＦＲＰロープ
の柔軟性を利用して、ロープの一端部に結び目を設けて
おき、ロープを熱硬化させて結び目をコンクリートとの
定着部とすることによって、定着長を短くするものであ
る。According to the present invention, a knot is provided at one end of the rope by utilizing the flexibility of the FRP rope, and the rope is heat-cured to make the knot a fixing portion with concrete. This shortens the fixing length.
【０００５】本考案のＦＲＰロープは、定着部とする一
端部にのみ結び目を設けておいてもよいし、両端に定着
部が欲しい場合は両端に結び目を設けておいてもよい。
また、中間部でもコンクリートとの定着性を向上させた
いとき中間部にも結び目を設けておけばよい。。本考案
のＦＲＰロープの配筋は通常柔軟な状態のＦＲＰロープ
を型枠内の所定の位置に配置し、ついでＦＲＰロープを
熱硬化させるという方法によって行われるが、ＣＦＲＰ
以外のＦＲＰロープは型枠内で熱硬化させることが操作
上困難を伴うので、ＣＦＲＰロープを含め、予め所定の
形状に熱硬化させたものを型枠内に配筋してもよい。な
お、型枠内で熱硬化させる場合でも端部を熱硬化させて
おく方が施工し易い場合があり、この場合は端部のみを
予め熱硬化させておく。型枠内での熱硬化はロープに電
気を通しロープの内部発熱を利用して行う。[0005] The FRP rope of the present invention may be provided with a knot only at one end serving as a fixing portion, or may be provided with knots at both ends if fixing portions are desired at both ends.
Also, when it is desired to improve the fixability to concrete at the intermediate portion, a knot may be provided at the intermediate portion. . The reinforcement of the FRP rope of the present invention is usually performed by arranging the FRP rope in a flexible state at a predetermined position in a mold, and then thermally curing the FRP rope.
Since it is difficult to thermally cure the FRP ropes other than the above in the formwork, it is also possible to arrange the heat-cured fibers having a predetermined shape in advance including the CFRP ropes in the formwork. In addition, even in the case of performing thermosetting in the mold, it may be easier to perform thermosetting at the ends, and in this case, only the ends are thermoset in advance. The thermosetting in the mold is performed by passing electricity through the rope and utilizing the heat generated inside the rope.
【０００６】本考案でいう結び目は２本のロープを結び
付ける結び目ではなく、１本のロープ内に作られた結び
目でロープを引っ張ると締まる結び目であり、古くより
知られている種々の結び目が利用される。The knot according to the present invention is not a knot connecting two ropes, but a knot formed in one rope and tightening when the rope is pulled. Is done.
【０００７】[0007]
【実施例】以下、図面を参照して、本考案を説明する。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.
【０００８】図１（ａ）は本考案の結び目の１例を示す
斜視図である。ロープ１の端部に結び目２が作られる。
この結び目２はロープを引っ張ると締まる結び目であ
り、縄梯子と同様に結び目を作ることによってロープ１
の延長方向が余り変えられない結び目である。FIG. 1A is a perspective view showing an example of the knot of the present invention. A knot 2 is made at the end of the rope 1.
This knot 2 is a knot that tightens when the rope is pulled, and the knot 2 is formed by knotting in the same manner as a rope ladder.
This is a knot whose extension direction cannot be changed much.
【０００９】図１では図示のため結び目２を緩めた状態
