Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a simple wire tensioning tool, and more specifically, a simple wire tensioning tool that allows even one person to restretch barbed wire efficiently and safely at farms, etc. Regarding tension wire fittings.

[Problems to be solved by conventional techniques and ideas]

Traditionally, when replacing barbed wire, the first step is to remove broken or old barbed wire. Because it was done by removing it, it often broke at the twisting part,
Moreover, it was a very time-consuming and labor-intensive task. What's more, the next step is to string new barbed wire over the replacement area, and for this work, one person holds the barbed wire in the direction they are going to string it, parallel to the ground along the previously driven pillars, and then holds the barbed wire in parallel to the ground. Another person was fixing the barbed wire with wire using pliers.

Therefore, it is extremely time-consuming and requires the formation of a work team of multiple people at all times, and an improvement has been desired.

It is an object of the present invention to solve the above-mentioned conventional problems and to provide a simple wire tensioning tool that allows even one person to re-stretch barbed wire efficiently and safely.

[Means and actions for solving problems]

That is, the present invention is a substantially T-shaped wire tensioning tool consisting of a rod-shaped rod 1 and a head 2 provided at one end of the rod-shaped rod so as to be orthogonal to the rod-shaped rod, and the rod-shaped rod has a Convex portions 3 are provided at predetermined intervals, and the head is provided with a pointed portion 4 at one end on the opposite side to the convex portion, and extends from the other end to the central portion at the orthogonal angle. A wave-shaped notch 5 is provided in the direction, and a groove 6 is provided to bisect the wave-shaped notch, and a bent portion 8 having a groove 7 is provided at the other end of the rod-like rod. The present invention provides a simple tensioning tool characterized by the following.

Hereinafter, one aspect of the present invention will be explained with reference to the drawings.
FIG. 1 is a front view of one embodiment of the simple tension wire of the present invention;
Figure 2 is its left side view, Figure 3 is its right side view,
FIG. 4 is a plan view thereof, and FIG. 5 is a bottom view thereof.

In the figure, reference numeral 1 denotes a rod-shaped rod, and a head 2 is provided at one end of this rod-shaped rod (at the left end in FIG. 1) so as to be perpendicular to this, and the whole has a substantially T-shape. ing. Note that orthogonal here does not only mean intersecting perpendicularly in the strict sense, but also includes a range that can be substantially equated with this.

This rod-shaped rod 1 has convex portions 3 on one side in the orthogonal direction (upward in FIG. 1) at a predetermined interval.
3, 3', 3'' are provided.It is preferable to provide at least three or more of these convex portions 3 in order to adapt to the shape and size of various pasture fences.This convex portion 3 is a commercially available Various types of fences (V-shaped steel, L-shaped steel,
There are no particular restrictions on the size, shape, etc., as long as it can be hung on a support such as square steel (square steel, etc.). Usually, the shape when viewed from the front is rectangular or trapezoidal, and the drawing shows a substantially trapezoidal shape.
This convex portion 3 is usually provided at a position closer to the head 2. Note that by appropriately selecting the width of the convex portions 3 and the interval between adjacent convex portions, the present invention can be applied to any of the various commercially available pasture fences. Normally, the length l ₁ of the bar-shaped rod 1 is around 256 mm, the width W ₁ of the convex part 3 is around 5 mm, and the distance between the convex parts 3 W ₂
is around 20 mm, but of course it is not limited to this. Note that "front and back" here refers to a range of about ±10 mm.

On the other hand, the head 2 is provided with a pointed part 4 at one end (at the lower end in FIG. 1) on the side opposite to the convex part 3 with the bar-shaped rod 1 in between. On the other hand, head 2
A wave-shaped notch 5 is provided in the orthogonal direction from the other end to the center. That is, when viewed from the front in FIG. 1, a wavy cutout 5 is provided whose shape is approximately wavy. It should be noted that this notch is sufficient as long as it allows the loose parts to be entwined, and for that reason it does not necessarily have to be wavy, but it is preferable to have a wavy shape to prevent the barbed wire from slipping, that is, from the standpoint of preventing danger. . Further, the head 2 is provided with a groove 6 that bisects the wave-shaped notch 5, as shown in FIG. As shown in FIG. 2 or 3, this kerf 6 has a substantially rectangular shape when viewed from the side. Note that the length _l2 of the head 2 is usually around 140 mm, and the kerf 6
The length _l3 is approximately 40 mm, but of course it is not limited to this. Further, the width W ₃ of the cut groove 6 is not particularly limited as long as it is at least as wide as possible to insert the barbed wire, but it is usually sufficient if it is about 5 to 6 mm. Furthermore, as shown in FIG. 2, the width W ₄ of the head 2 may vary slightly depending on the location, so it is difficult to determine it unambiguously, but a width of about 15 mm to 20 mm is sufficient.

Further, the other end (the right end in FIG. 1) of the bar-shaped rod 1 is provided with a bent portion 8 having a groove 7. The groove 7 can be of any size or shape as long as the barbed wire can be entangled therein, but as shown in Figs. It may be in the form of Also, the bending part 8
The bending direction may be any direction other than the orthogonal direction, but it is usually bent toward the front when viewed from the front, as shown in FIGS. 2 to 5. This bent portion 8 normally forms an angle of about 45 degrees with respect to the bar-shaped rod 1.

Although steel is usually used as the material for the simple tension wire of the present invention, it is not limited to this, and any type of material may be used as long as it can perform the same function.

The simple tension wire of the present invention can be manufactured by, for example, integral molding or forging, but it can also be easily and inexpensively produced by welding a chisel to a commercially available steel bar and grinding a predetermined portion.

A method of using the simple tension wire of the present invention as described above will be explained with reference to the drawings. FIGS. 6a to 6c are explanatory diagrams showing an example of how to use the simple tension wire of the present invention.

First, the barbed wire fixing wire is struck from above using the pointed part 4 to cut it, and broken or old barbed wire is removed.

Next, new barbed wire is to be strung, but first the barbed wire is fixed to the original support using pliers or the like in the usual manner. Next, as shown in FIG. 6a, the barbed wire A is passed through the cut groove 6 of the simple wire tensioning device B, and the loose portion C of the barbed wire A is entwined with the corrugated cutout portion 5.

Then, the simple wire tensioning device B of the present invention is strongly pushed in the direction in which the barbed wire A is stretched, or the tension convex portion 3 is placed on the third support D at a distance that allows the wire to be stretched depending on the topographical condition (Fig. 6). b). Therefore, using the prop as a fulcrum, we applied Teiko's principle and rotated the simple tensioning tool B.
When the groove 7 is entangled with the barbed wire A, the barbed wire A becomes taut, and while the barbed wire A is kept in tension as described above, the barbed wire B can be fixed with a fixing wire using pliers or the like. can. Although FIGS. 6a to 6c show an example of fixing to a substantially L-shaped support using equilateral angle steel, it is also possible to fix to a support using V-shaped steel in the same manner.

Thereafter, after fixing with a predetermined number of columns in the same manner, the previous columns may be fixed in sequence with pliers or the like.

〔Example〕

Examples of the simple tension wire of the present invention are shown below.
The present invention is not limited to this unless it exceeds the scope of the present invention.

Example 1 A chisel (octagonal 16 mm) was welded to two steel bars (φ13 mm), and after welding, they were ground to produce tension wire tools having shapes as shown in FIGS. 1 to 5. In addition, the length l ₁ of the bar-shaped rod 1 of this tension wire tool is 265 mm, and the length l 1 from the head 2 to the convex part 3
The distance W ₃ is 65 mm, the width W ₁ of the convex part 3 is 5 mm,
The distance W ₂ between the convex parts 3 is 20 mm, the difference between the upper and lower bases of the convex parts 3 is 2 mm, and the length l ₂ of the head 2 is 140 mm.
The length _l3 of the cut groove 6 is 40 mm, the distance _l4 from the lower end of the head 2 to the rod 1 is 70 mm, and the length l5 of the corrugated notch ₅ is
13 mm, and the distance l ₆ between adjacent wave-shaped notches is 5 mm. Furthermore, the width W ₄ of the cut groove 6 is 6 mm, and the width of the head 2
_W5 is 19mm.

When we used this wire tensioning tool to re-stretch the barbed wire of a fence post made of equilateral angle steel, we found that:
In a straight section, the line could be stretched up to 20 meters without sagging, and could be stretched by one person.

[Effect of idea]

According to the simple wire tensioning tool of the present invention as described above, even one person can efficiently and safely perform the work of re-stretching barbed wire.

What's more, in a straight line, the wire can be stretched up to 20 meters without sagging, so there is no need to organize a work team, which saves a lot of labor.

Furthermore, the simple tension wire of the present invention can be applied to any of the various commercially available fences (V-shaped steel, L-shaped steel, square steel, etc.), and the dimensions can be taken into consideration as shown in the examples. The same equilateral angle shape steel (L shape steel)
It can also be used for both 40 x 40 x 1800 and 50 x 50 x 1800 standards. Moreover, by using the dimensions as shown in the embodiment, the groove of the bar-like rod can always be positioned between the loose parts of the barbed wire, so that it is extremely safe to handle.

Therefore, the present invention can be effectively used in ranches and other places, such as for repairing and replacing barbed wire.
