作業の能率向上等を考慮し、本発明を創案した。By the way, when fixing each strand of the continuous fiber reinforced plastic stranded wire with an irregular shaped curing material,
It is necessary to separate each strand from each other. If it is not done properly, the expansion pressure of the expandable filler injected into the cylindrical body surrounding the strand at the end of the stranded wire will start to work when using the expandable filler as the amorphous hardening material. The expansion pressure crushes the voids in the cross section of the stranded wire, and the cross section of the stranded wire contracts.Therefore, sufficient expansion pressure for fixing the wire cannot be obtained, and the wire can be securely fixed. Disappear. Further, when an adhesive is used as the amorphous curing material, only the element wires of the outermost layer or the layers in the vicinity thereof are bonded and fixed. Further, when the individual strands are separated from each other, the strands forming the stranded wire also have an elastic modulus in the direction orthogonal to the axial direction, which makes untwisting work and positioning work difficult. Therefore, consideration in this respect is desirable. These points can be regarded as problems that occur when fixing each strand of the continuous fiber-reinforced plastic stranded wire when the conventional technique is implemented without any special measures. The present inventor is to keep the individual wires apart from each other, which is the degree of filling in the case of filling with an irregular shaped curing material,
The present invention was devised in consideration of the volume filling rate, which in turn affects the yield strength when the strands of the stranded wire are fixed, and in consideration of improving the efficiency of untwisting work.

続することを指す。In order to achieve the above-mentioned object, the present invention is to unwind the end of a stranded wire made of continuous fiber reinforced plastic composed of a plurality of layers, and to remove the stranded wire of the stranded wire. In the method of arranging in a divergent shape, and fixing, the strands of the twisted wire are separated from each other by fitting a circular hollow ring between adjacent layers on the inner side of the tip of the section of the twisted wire of the layer, The strands are arranged in a divergent shape, and an indeterminate hardening material is injected into a cylindrical body inserted so as to surround the strands arranged in a divergent shape, and the cylindrical body is bonded or fixed to the tubular body. On the other hand, the continuous fiber-reinforced plastic stranded wire fixing method is characterized in that the strand is fixed. In the present invention, the splayed shape broadly refers to a shape in which a continuous fiber-reinforced plastic stranded wire is unfixed and fixed for joining or fixing, and is used in a meaning that broadly includes a barrel shape or a cone shape. The circular hollow ring is used between the layers of a plurality of layers due to its role, but it is not always used between all the layers, and some layers may be unused depending on the situation at the site. Like the conventional socket, the tubular body must have a length longer than the axial length of the strands of wire arranged in a divergent shape, and must have a proof stress commensurate with the axial force received by the continuous fiber-reinforced plastic stranded wire. However, the difference is that it is not necessary to intentionally provide a taper on the inner surface of the socket.
Further, the tubular body is preferably made of continuous fiber reinforced plastic, like the stranded wire. An expansive filling material or an adhesive material can be used as the irregular-shaped curing material. Here, joining means connecting two twisted wires, and fixing means connecting an end portion of one twisted wire to another member or the like.

It is possible to facilitate the unwinding work of the twisted wire at the end of the twisted wire made of fiber-reinforced plastic. For this reason, it is preferable that the front end surface of the circular hollow ring is formed of an inclined surface and chamfered from the outer diameter toward the inner diameter. In addition, the circular hollow ring is provided with a slit in the axial direction to absorb the error in the diameter of the layer into which the circular hollow ring is inserted, and its spring force grips the stranded wire of the inner layer, It can help to position the hollow ring. In addition, protrusions are provided at equal intervals on the outer circumference of the circular hollow ring,
The strands of the stranded wire of the same layer may be separated in the circumferential direction via the protrusions.
