FIG. 11 is a partial front view showing a conventional fence constructed on an inclined ground.

  As shown in FIGS. 7 to 9, the conventional fence includes a support column 11 and a fence body 12 attached between the support columns 11.

  The fence body 12 is composed of a lattice wire net 13, upper and lower trunk edges 14a and 14b, and left and right trunk edges 15a and 15b. The lattice wire mesh 13 is formed of a crimp wire mesh (see FIGS. 8 and 9). The upper and lower ends of the vertical line 13a are fixed to the upper and lower body edges 14a and 14b, and the left and right end parts of the horizontal line 13b are the left and right body edges 15a, It is fixed to 15b. The crimp wire mesh is a wire mesh that is knitted in a lattice shape by alternately intersecting vertical lines 13a and horizontal lines 13b that are bent into a waveform at a predetermined pitch.

  When constructing a conventional fence on an inclined ground, as shown in FIG. 10, the lattice metal mesh 13 is obliquely deformed and constructed on an inclined ground as shown in FIG. 11. Since the lattice wire mesh 13 is formed of a crimp wire mesh, it is easily deformed.

  According to the conventional fence described above, the use of a crimp wire mesh that can be easily deformed obliquely as the lattice wire mesh 13 makes it easy to construct an inclined land. Further, the grid metal mesh 13 can be attached to the upper and lower body edges 14a and 14b by fastening the presser fitting 17 by the conventional fixing structure.

  However, since the lattice wire mesh 13 of the conventional fence only crosses the vertical lines 13a and the horizontal lines 13b alternately, the vertical lines 13a or the horizontal lines 13b at the end portions are easily disconnected. In particular, it is easy to come off when the grid wire mesh 13 is obliquely deformed when dealing with sloping ground, and once it comes off, it takes time and effort to restore it.

  Further, in order to attach the grid wire mesh 13 to the upper and lower body edges 14a, 14b by the conventional fixing structure, the horizontal wire 13b is attached by the presser fitting 17 at a predetermined interval, so that compared to the case where the grid wire mesh 13 is attached over its entire length. The attachment strength of the grid wire mesh 13 was low.

  Further, since the horizontal wire 13b is attached via the bolts and nuts 18 by the plurality of presser fittings 17, it takes time and effort to attach the lattice wire mesh 13.

  Therefore, the object of the present invention is that there is no possibility that the vertical or horizontal line at the end will be detached even if it is deformed obliquely when dealing with an inclined land, and the grid wire mesh can be attached to the trunk edge over its entire length. An object of the present invention is to provide a fence that can increase the strength of attachment of a wire mesh to the trunk edge, and can easily and reliably attach the lattice wire mesh to the trunk edge in a short time.

  The present invention has been made to achieve the above object, and is characterized by the following.

The invention according to claim 1 is a pipe-like shape in which slits are formed along the entire length in the longitudinal direction, to which a lattice wire net knitted with a vertical line and a horizontal line bent into a waveform at a predetermined pitch, and to which the lattice wire mesh is attached. And a curl portion to be inserted into the upper and lower body edges is formed at the upper and lower ends of the vertical line, and a center line of the curl part is orthogonal to the vertical line It has a special feature.

  According to the present invention, by forming the curled portion at the end portion of the vertical line or horizontal line, there is no possibility that the vertical line or horizontal line at the end portion will be disconnected even when the lattice metal mesh is obliquely deformed when dealing with an inclined land.

  Further, according to the present invention, the grid wire mesh can be attached to the trunk edge over the entire length by inserting the curled portion of the grid metal mesh into the trunk edge where the slit is formed over the entire length in the longitudinal direction. In addition, it is possible to increase the strength of attaching the grid wire mesh to the trunk edge.

  Further, according to the present invention, it is only necessary to insert the curl portion of the lattice metal mesh into the slit formed on the trunk edge, so that the attachment of the lattice metal mesh to the trunk edge can be performed easily and reliably in a short time.

An embodiment of the fence of the present invention will be described with reference to the drawings.

FIG. 1 is a partial front view showing a lattice metal mesh used in the present invention.

As shown in FIG. 1, a grid wire mesh 1 used in the present invention is formed by knitting by alternately intersecting vertical lines 1a and horizontal lines 1b bent into a waveform at a predetermined pitch. The curl portion 2 (the curl portion at the lower end portion is not shown) is formed at the end portion. In this example, the curled portion 2 is obtained by curling the end portion of the vertical line 1a once in a circular shape, but may be curled multiple times. The outer diameter of the curled portion 2 is smaller than the inner diameter of the upper and lower body edges 6a and 6b described later, and larger than the width of the slit 8 described later.

In this way, by forming the curled portions 2 at the upper and lower end portions of the vertical line 1a, there is no possibility that the horizontal line 1b at the end portion is detached from the vertical line 1a when the lattice wire mesh 1 is deformed obliquely. Moreover, since the lattice metal mesh 1 used for this invention consists of a crimp wire mesh, it deform | transforms easily. When curled portions are formed at both left and right end portions of the horizontal line 1b, there is no possibility that the vertical line 1a at the end portion also deviates from the horizontal line 1b.

  Next, the fence 3 of the present invention will be described. As shown in FIG. 3, the fence 3 according to the present invention includes a fence body 5 attached between columns 4.

The fence body 5 is composed of a lattice wire net 1 used in the present invention, upper and lower trunk edges 6a and 6b, and left and right trunk edges 7a and 7b.

  As shown in FIGS. 3 and 4, the upper trunk edge 6 a is formed of a slit 8 formed over the entire length of the circular pipe in the longitudinal direction. Similarly to the upper body edge 6a, the lower body edge 6b is formed by forming a slit in a circular pipe over the entire length in the longitudinal direction. In addition, the cross-sectional shape of the upper and lower trunk edges 6a and 6b is not limited to a circle, and may be a pipe having a slit, such as a corner, a triangle, or an ellipse.

  The structure of the left and right trunk edges 7a and 7b is not particularly limited. That is, as in the case of the upper and lower body edges 6a and 6b, it may be a pipe having slits or a structure in which the horizontal line 1b is sandwiched between flat plates. When the left and right trunk edges 7a and 7b are pipe-shaped with slits, curled portions are formed on the left and right ends of the left and right trunk edges 7a and 7b in the same manner as the upper and lower trunk edges 6a and 6b. .

In order to construct the fence 3 of the present invention on the sloping ground, as shown in FIG. 6, the grid wire mesh 1 used in the present invention, which is attached between the upper and lower trunk edges 6a and 6b, is slanted according to the sloping ground to be constructed. Deform. Since the curled portion 2 of the vertical line 1a of the grid wire mesh 1 is inserted into the upper and lower body edges 6a and 6b, the angle formed by the vertical line 1a and the upper and lower body edges 6a and 6b can be freely adjusted. .

  In addition, when the curled portion 2 is inserted into the upper and lower body edges 6a and 6b, the lattice wire mesh 1 will not come out of the upper and lower body edges 6a and 6b, so the lattice wire mesh 1 is firmly attached to the upper and lower body edges 6a and 6b. be able to.

  As described above, according to the present invention, by forming the curled portions at the upper and lower end portions of the vertical line, there is no possibility that the horizontal line at the end portion is deviated from the vertical line.

  Further, according to the present invention, a slit is formed on the upper and lower body edges over the entire length in the longitudinal direction, and the lattice metal mesh is curled on the upper and lower body edges by inserting the curl portion of the lattice metal mesh from the end of the slit. Can be attached.

  In addition, according to the present invention, the angle formed between the vertical line of the lattice metal mesh and the upper and lower body edges can be freely adjusted, so that it is possible to cope with any inclined ground.
