The above cables are formed by bundling multiple cable strands made of steel wire, steel strands, rope, etc., and those used for large structures have a length of 200 to 300 m and a weight of 200 to 300 m. 30~
It can reach up to 50 tons. It is very difficult to manufacture this entire cable in a factory and transport it to the site. For this reason, large-sized cables are constructed by transporting each cable strand to the site and stretching and fixing it one by one. That is, after the end of the cable wire is locked by a chuck provided on the jack, the jack is operated and the cable wire is pulled and retreated, and then an anti-slip uneven portion is formed on the inner peripheral surface. The cable wire is fixed to the fixing part by driving the wedge member. With this method, accidents often occur in which the wedge member falls off when the cable strand vibrates due to wind blowing during construction work, and the length of the cable strand is determined based on the tension force acting on the jack. Therefore, it is extremely difficult to set its length accurately.

With the end of the cable wire 10 held by the jack 42, the jack 42 is activated to pull the cable wire 10 backward, and as shown in FIG. After being positioned at the rear, the split wedge piece 45 is inserted into the gap between the inner peripheral surface of the insertion hole 40 of the pressure plate 41 and the cable strand 10 from the end side of the cable strand 10 . Next, as shown in FIG.
and guide member 43 is removed and the cable element 1 is removed.
When the clamping state of the end portion of the cable wire 10 is released, the cable wire 10 is bent due to its own weight, tension is applied, and the bulging portion 12 tends to move forward. As a result,
The bulging portion 12 comes into contact with the rear end of the wedge piece 45, and the wedge piece 45 is pushed into the insertion hole 40 of the pressure plate 41,
The cable wire 10 is held and fixed by the wedge effect of the wedge piece 41.

As described above, according to the present invention, the stretched length of the cable strands 10 is set by the bulge 12, so that the lengths of the cable strands 10 can be very easily aligned accurately and uniformly. Can be done. Further, a bulge 12 is provided at the rear end of the wedge piece 45 that fixes the cable wire 10.
This arrangement has the advantage that the wedge piece 45 can be reliably prevented from falling off the pressure plate 41 even during construction work. Furthermore, since the cable wire 10 is configured to be fixed to the pressure plate 41 by being held by the wedge pieces 45, there is no need to increase the amount of bulge of the bulging portion 12, and the wedge piece 45 should be bulged to an extent that can prevent it from falling off, and it is usually sufficient to set the outer diameter of the bulged portion 12 to about 1.05 to 1.30 times the outer diameter of the cable strand 10. Note that the outer diameter of the bulging portion 12 is
The outer diameter of the cable wire 10 may be set to about 1.45 to 2.00 times the outer diameter of the wedge piece 45, and the cable wire 10 may be fixed by bringing this bulging portion 12 into contact with the rear end portion of the wedge piece 45. In this case, there is no need to form uneven parts on the inner circumferential surface of the wedge piece 45 to prevent slipping as shown in the figure, and it can be formed on a smooth surface, so that the outer circumferential surface of the cable wire 10 is not damaged. It is possible to prevent a decrease in the strength of the cable wire 10 due to adhesion.
In addition, when the wedge piece 45 is made of a soft material such as synthetic resin, aluminum, copper, zinc, etc., the wedge piece 45
Separate washers 47, 47 made of a hard material such as steel as shown in FIG. It is desirable to configure the structure so that damage to the wedge piece 45 due to local stress acting on the wedge piece 45 is prevented.
Furthermore, it is not necessary to use the wedge piece 45 as a locking member for fixing the cable wire 10, but instead, semi-cylindrical locking pieces 48, 48 are used as shown in FIG. The above-mentioned locking piece 4
The cable element 10 may be fixed by plastically deforming the cable element 8 .

In addition, when the cable strand 10 is stretched in a substantially no-load state by a means such as stretching a temporary rope above the cable 1 and supporting multiple locations of the cable strand 10, can easily connect the cable wire 10 without using the jack 42 or the like.
One end 11 of the pressure plate 41 can be inserted into the insertion hole 40 of the pressure plate 41. Therefore, it is not necessary to provide a clamped portion for the jack 42 on the cable wire 10, and as shown in FIG.
It can also be formed at the end of 0. This is the first
This will be explained using Figure 3. First, the cable wire 10 is placed at a predetermined position above the cable wire 10 to be stretched.
After the temporary rope 7 is stretched along the cable 10, the upper end of the cable wire 10 is fixed to the fixing part 70. In this state, the cable wire 10 becomes slack due to its own weight as shown by the imaginary line, and the bulge 1 at the lower end
2' does not reach the pressure plate 41. From this state, the cable wire 10 is lifted up by a plurality of lifting ropes 71 attached to the temporary rope 7 at appropriate intervals, and brought into a straight state as shown by the solid line. As a result, the bulging portion 12' moves toward the pressure plate 41 and is inserted into the insertion hole 40 of the pressure plate 41 as shown in FIG. It will be located behind the plate 41. Then, when the wedge piece 45 is set in this state and the holding by the lifting cable 71 is released, the cable element 1
0 again becomes loose due to its own weight as shown by the imaginary line in FIG. It is crimped and fixed to the pressure plate 41 via the piece 45.

Furthermore, after the cable wire 10 is stretched, the first

and an injection pipe 51 connected to the lid 50.
The filler 5 made of a time-curable substance such as a synthetic resin may be injected into the insertion hole 40 through the filler 5 and hardened. In this case, since the filler 5 generates a gripping force on the cable strand 10, the filler 5 acts to relieve stress against fluctuations in the tension of the cable strand 10, thereby increasing the fatigue strength of the cable strand 10. It has the advantage of being able to increase the
Furthermore, as shown in FIG.
If the above-mentioned filler 5 is filled in the inside,
The bondability between the filler 5 and the pressure plate 41 is improved, and the stress relaxation effect of the filler 5 can be improved.

As explained above, in this invention, the tension length of the cable wire is set by the expansion part formed in the cable wire, so the tension length of each wire composing the cable can be accurately and accurately set. This has the advantage that it can be arranged uniformly and that the wedge pieces for locking the cable wires to the fixing part can be reliably prevented from falling off the pressure plate.
