Abstract

<P>PROBLEM TO BE SOLVED: To stably support a base part of a fence net composed of upright vertical steel wires on the ground installed so as to correspond to the going underground of a small animal by digging the underground, without requiring burying the lower part of the vertical steel wires in the ground, keeping vertical standing of the vertical steel wires at a tilted ground, and without digging a groove for laying the fence net underground by the bent part at the lower part of the vertical steel wire contacting with the ground. <P>SOLUTION: The fence net for preventing the invasion of the small animal is obtained by mutually parallelly arranging a plurality of the vertical steel wires 1 at an even interval, connecting the vertical steel wires by inserting and crossing the wires into and with the wave-shaped bent parts 3 of wave-shaped steel wires 2, and bending the lower part of each of the vertical steel wires frontward or rearward so as to be in the nearly same plane. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a fence (fence) for preventing entry of small animals, which is established on both sides of a railway or a road by crossing parallel vertical steel wires and parallel horizontal steel wires.

  In the conventional fence wire mesh for small animal entry prevention, the lower end portion of the parallel vertical steel wire is extended downward from the bottom horizontal steel wire to form a buried portion, and the buried portion prevents entry of the small animal from below the ground (for example, Patent Document 1).

  The buried part needs to excavate the ground, and after digging the buried groove in the horizontal direction or the inclined direction in order to make the parallel vertical steel wire upright on the horizontal or inclined ground, the vertical steel wire buried part is arranged in the buried groove. Then, it was necessary to refill the buried trench.

  The above backfilling requires soil compaction at both the front part (front part) and rear part (back part) of the established vertical steel wire. Alternatively, there is a problem that the front and back sides are separated by the wire mesh and the front and back or front and back simultaneous compaction operations cannot be performed.

  Further, the buried groove has a problem that the ground cannot be formed by a rock, and it is necessary to cut the buried portion of the vertical steel wire due to the fluctuation of the ground.

JP 2002-81231 A

  The present invention not only can cope with submarine excavation under the ground of small animals, but also does not require the underground burial below the vertical steel wire, and maintains the vertical steel wire upright on the inclined ground and is in contact with the ground. The object is to stably support the base of a fence wire mesh by an upright vertical steel wire on the ground without excavating a buried groove by a lower bent portion.

In order to achieve the above object, the present invention firstly arranges a plurality of vertical steel wires in parallel with each other at equal intervals, and connects the vertical steel wires so as to be inserted and crossed into the corrugated portion of the corrugated horizontal steel wire, A fence wire mesh for animal entry prevention formed by bending the lower part of each vertical steel wire forward or backward in substantially the same plane;
Second, the fence wire mesh for preventing animal entry according to the first invention, wherein the bent lower portion of each vertical steel wire intersects the horizontal steel wire,
Third, the fence metal mesh for preventing animal entry according to the first or second invention, wherein a bent portion formed on the vertical steel wire and a bent portion formed on the horizontal steel wire are crossed,
Consists of.

  Therefore, the lower part of the vertical steel wire is in contact with the ground, the fence wire mesh is erected on the horizontal and inclined ground by the upper vertical steel wire and the corrugated horizontal steel wire, and the lower part is fixed by a vertical steel pile driven into the ground The fence wire mesh can be established on horizontal and / or sloping ground.

  At the time of establishment, the direction of the bent lower portion can be adapted to the ground by changing the direction by contacting the bent lower portion with one or the other in parallel with the ground. In this case, the upright vertical steel wire is rotated at a certain angle in one or the other.

  Also, the upright vertical steel wire can be inclined in parallel to the right or left, whereby the vertical steel wire can be made to stand upright on the inclined ground. At that time, the bent lower part rotates to the right or left at the same angle.

Since the present invention is configured as described above, in establishing the fence wire mesh by the vertical steel wire on the ground, not only can the vertical steel wire fence be established upright on the horizontal and inclined ground,
It is not necessary to embed the bent lower part of the vertical steel wire in the ground, and the width of the lower bent part can be reduced by simply rotating the vertical vertical steel wire at the lower part to the right or left, to wide or narrow horizontal or inclined ground. Accordingly, there is an effect that it can be contacted accordingly and strongly fixed to the ground with a nail or a hooked steel pile.

The vertical steel wires 1 of the same length are arranged in parallel with each other at a plurality of equal intervals, and the vertical steel wires 1 are inserted into the corrugated bent portions 3 of the two or three corrugated horizontal steel wires 2 and 2 in that state. The fence wire mesh 5 shown in FIG. 1 (a) is formed by crossing and connecting vertically and horizontally.

  The lower portions of the vertical steel wires 1 and 1 are bent forward or backward in substantially the same horizontal plane, and the bent lower portion 4 is also formed in the corrugated bent portion 3 of the two or three corrugated horizontal steel wires 2 in the bent lower portion 4. The vertical steel wires 1 are inserted and crossed (shown in FIG. 1 (c)).

  The length of the bent lower portion 4 is about 200 mm to 700 mm.

  As shown in FIG. 3, in the upright vertical steel wire 1, the curved portions 3, 3 of the upper and lower horizontal steel wires 2, 2 in the three corrugated horizontal steel wires 2, 2, 2 are 3 can be opposed to each other.

  The waveform curve portion 3 may be one that is alternately continuous as shown in FIG. 2 (a), or one having a rectangular concave shape as shown in FIGS. 5 (b) and (d).

  And the curvature of the corrugated curved part 3, 3 'is larger than the diameter of the vertical and horizontal steel wires 1, 2 intersecting, and the vertical and horizontal steel wires 1, 2 can move inside the corrugated curved part 3, 3' at the intersecting part. it can.

Further, the bending angle between the vertical steel wire 1 and the bent lower portion 4 is not necessarily 90 degrees, and can be slightly inclined from the upright state as shown in FIG.
In the present invention, as shown in FIG. 1 (a), the vertical steel wire 1 is upright or tilted as shown in FIG. 4 (a) to stand on the ground 6, and the bent lower part 4 is in contact with the ground 6 and its state Thus, the vertical steel wire 1 can be parallel-tilted as shown in the virtual lines in FIGS. At that time, the vertical steel wire 1 of the lower bent portion 4 rotates in the direction of arrow a.

  Further, as shown in FIG. 1B, the width c of the bent lower portion 4 can be reduced by inclining the vertical steel wire 1 of the bent lower portion 4 from the solid line position to the virtual line position. At that time, the upright vertical steel wire 1 on the fence side rotates in the arrow b direction.

  The tilting of the upright vertical steel wire 1 (FIG. 1 (c) imaginary line) and the inclination of the bent lower part 4 (FIG. 1 (b) imaginary line) can be performed simultaneously according to the topography of the ground 6. Accordingly, the triangular overlap 4 ′ of the bent lower part 4 shown in FIG. 6 can be avoided, and the bent lower part 4 is brought into contact with the ground 6 corresponding to the inclination of the fence establishment ground 6, the width c, etc. An anchor) is driven into the ground 6 and the lower part 4 is fixed to the ground 6 to form a fence by standing or upright vertical steel wires 1, 1.

  According to the present invention, it is not necessary to excavate a buried groove for establishing the fence wire mesh 5 on the horizontal or inclined ground 6, and the backfilling work may be about a heap, and a small animal entry prevention fence is simply established on the horizontal and inclined ground 6. be able to.
