Description

  The present invention relates to an intrusion prevention fence, and more particularly to an animal intrusion prevention fence using a wire mesh using a crimped wire.

  For example, on an expressway road or a main railway line constructed in the mountains, animal intrusion prevention fences are provided on both sides of the road so that small animals do not enter the road. Conventionally, this fence has generally been used with a welded grid wire between the vertical and horizontal torso edges. In order to construct a fence using this welded grid wire on a sloping ground, The grid wire mesh welded to the vertical line by changing the angle of the horizontal line according to the angle was created and constructed. This was very poor in workability, and it was very difficult to cope with each inclination angle. Another method of installing a welded grid wire fence on an inclined ground is to cut the top and bottom of the welded wire mesh according to the inclination angle at the construction site, but the workability is poor and the aesthetics are also good. It was bad.

In view of the above problems, several patents have been filed for grid metal meshes that can cope with sloping ground.
For example, there is (1) Japanese Patent Laid-Open No. 61-85670 “Net fence that can be installed on sloping ground”. This prior art discloses a net fence that can be constructed on an inclined land, in which the intersection of a vertical line and a horizontal line constituting the wire mesh portion of the fence is simply held in contact. However, in this conventional example (1), since the intersection point is not fixed, the wire may be shifted horizontally or vertically, and the wire mesh does not collapse until the wire mesh is fixed at the horizontal trunk edge or the vertical trunk edge. Need to be maintained. Therefore, it is necessary to pay sufficient attention at the time of packing, transporting and construction, and once the wire mesh breaks down, it takes time and effort to return it.

(2) Japanese Patent Application Laid-Open No. 2002-81231 “Fence wire mesh for small animal entry prevention” has a concave bent portion or a curved portion for combining the vertical line and the horizontal line at the intersection of the vertical line and the horizontal line of the fence metal mesh. A fence wire net for preventing entry of small animals using a wire net that is provided and configured by fitting the concave portions to each other is disclosed. However, the fence wire mesh of this conventional example (2) also has a U-shaped concave portion in the wire, and it is difficult to shift, but in the point that the intersection of the vertical line and the horizontal line is simply held in contact ( Similar to 1), there is a possibility that the wire mesh may be broken as described above, and it takes time and effort to produce a wire rod having a U-shaped concave portion, and the productivity is poor.

  Conventionally, JIS standard crimp wire mesh has not been used as much for fences. This is because the crimp wire mesh is not arranged in the corrugated uneven part where the vertical line and horizontal line are adjacent to each other, but is finely knitted at a constant pitch with a plurality of uneven parts separated. The restraint force was strong and it was able to cope with only a slight slope. In addition, it can be deformed into parallelograms when knitted at a large pitch so that it can be used on slopes, and it can be used on slopes, but there is less restraining force on the wire, and the wire is easily displaced and the wire mesh collapses. This is because there was a drawback. In addition, there is a crimp wire mesh fence that is knitted fairly densely, but the binding force between the wires is strong, and it was able to cope with only a slight slope, and it was a fence aimed at landscape characteristics by tightly knitting . In order to install this crimp wire mesh on sloping ground, we knitted vertical lines and horizontal lines into a grid pattern with a certain amount of space, and kept parallelograms so that they can be deformed. Sometimes it is deformed so that the upper and lower sides are inclined while maintaining a parallelogram, and is installed on an inclined ground.

  Inclined land type crimp wire mesh is knitted as described above. In this case, in order to knitting the vertical and horizontal lines so that they can be deformed while maintaining the parallelogram, it is necessary to secure a certain degree of freedom at the intersections. There is. For this reason, the vertical line and the horizontal line are not arranged to be adjacent to the corrugated uneven portions, but are knitted so as to be positioned with a plurality of uneven portions separated. For this reason, the conventional crimped wire mesh for sloped land has a structure in which the wire rod is easily displaced as in the conventional examples of (1) and (2), and it is necessary to pay sufficient attention to handling from the time of manufacture to construction. In addition, once the wire mesh collapsed, there was a problem that it took time and effort to return it.

Further, as a technique superior to these conventional techniques, as shown in FIGS. 15 to 19, a fence body made of a wire mesh using a crimped wire material in which vertical lines 2 and horizontal lines 3 are assembled is provided with a plurality of support columns 8. In the fence fixed in between, a set of side vertical lines 2 composed of two or more lines and a set of horizontal lines 3 composed of two or more lines are intertwined to form a four-sided frame 6, and the four-sided frame 6 is fenced A fence including a fence main body formed on the upper and lower portions and the middle portion of both sides of the main body 19 is also known.
In the above embodiment, the upper portion of the fence body 19 is attached with the claw 23, the mounting bolt 24, and the body edge mounting bracket 25 formed on the body edge 12 (see FIGS. 19a and b), and the side end of the fence body 19 is attached to the column 8 The end of the fence main body 19 is fixed to the support column 8 with the presser fitting 29, the U bolt 30 and the nut 31 (see FIGS. 19c and d), or the support post 8, the presser fitting 32, and the bolt 28. Moreover, the end of the fence body 19 is fixed to the support column 8 by the nut 34 (see FIGS. 19e and f).
Moreover, in this embodiment, a set of horizontal lines 3 composed of two lines is embedded in the underground portion (see, for example, Patent Document 3).

JP 61-85670 A JP 2002-81231 A JP 2006-152616 A

In the fence in the form of forming the above-mentioned four-sided frame, a set of side vertical lines 2 consisting of two or more lines and a set of horizontal lines 3 consisting of two or more lines are intertwined to form a four-sided frame. The four-sided frame 6 is formed at the upper end and the lower part on both sides of the fence body 19, and a pair of horizontal lines 3 consisting of two or more lines are arranged at the upper end and the lower part, and the two lines intertwined with these A set of vertical lines 2 composed of the above is disposed on both sides to form a frame-like portion having high rigidity. Therefore, it can be deformed while maintaining a parallelogram, can be easily transported, and can be firmly attached to the support column 8 side so as to overlap both rigid side portions of the frame-like portion.
However, in this embodiment, a set of horizontal lines 3 consisting of two lines is embedded in the ground portion of the ground 7 to prevent digging of the small animal under the fence body, but it is effective for small animals. Although it functions, it was insufficient for digging animals such as wild boars or dogs, so it may be possible to embed multiple sets of horizontal lines 3 consisting of two main lines in the ground. Since the vertical lines become longer and at least four horizontal lines are arranged at the minimum, the degree of freedom of horizontal line arrangement is reduced, and the number of horizontal lines embedded in the underground increases, which is not economical.
Therefore, there has been a demand for an economically effective improvement measure against the point that it is insufficient for digging animals while taking advantage of the above-mentioned four-sided frame.
An object of the present invention is to provide an animal intrusion prevention fence that can advantageously solve the problem of animal digging while taking advantage of the above-mentioned four-sided frame.

In order to solve the above-mentioned problem advantageously, in the animal intrusion prevention fence according to the first aspect of the invention, a fence body made of a wire mesh using crimped wire rods, in which vertical lines and horizontal lines are combined, is fixed between a plurality of columns. In the animal intrusion prevention fence, the wire mesh is configured such that vertical lines and horizontal lines each having a corrugated uneven portion are arranged in parallel in the vertical and horizontal directions. It is passed through and engaged with the concavo-convex part of the horizontal line above the main line, the horizontal line of the two or more lines is taken as one set, the adjacent horizontal line sets are separated from each other by 3 pitches or more, and the wire mesh can be transformed into a parallelogram. A set of side vertical lines consisting of two or more lines and a set of horizontal lines consisting of two or more lines are intertwined to form a four-sided frame, and the four-sided frame is formed on both sides of the fence body. At the lower end, a plurality of Horizontal line group for digging prevented by an animal comprising a lines is formed, lateral line group, at intervals of 1.5 pitch or 2.5 pitch offset relative to the vertical line of the waveform Holding from front and back for each vertical line Are alternately arranged one by one so that they can be deformed into parallelograms, and at least three horizontal lines in the horizontal line group are embedded in the ground together with the lower end portions of the vertical lines. It is characterized by.
Further, in the second invention, in the animal intrusion prevention fence according to the first invention, 1.5 pitches are substituted for at least three horizontal lines at the lower end portions spaced by 1.5 pitches or 2.5 pitches adjacent to each other. It is characterized in that it is passed through and engaged with the concave and convex portions of the horizontal lines of at least three lower end portions which are spaced so that a deviation and a 2.5 pitch deviation are mixed.
In the third invention, in the animal intrusion prevention fence according to the first invention or the second invention, the upper ground part spaced from the horizontal line of at least three lower ends is shifted by 1.5 pitch or 2.5 pitch. It is characterized in that a plurality of horizontal lines for the ground part are provided at intervals.

According to the fence using the wire mesh using the crimped wire of the present invention, the following effects are obtained.
(1) In a fence made of a wire mesh using crimped wire rods in which a vertical line and a horizontal line are assembled, the vertical line and the horizontal line in which the corrugated uneven portion of the wire mesh is formed are arranged in parallel in the vertical and horizontal directions. Since the line is passed through and engaged with the concave and convex portions of two or more horizontal lines that are offset by an adjacent half pitch, a quadrilateral frame is formed by the adjacent two lines, and the wire rod is not displaced, A wire mesh can also be constructed by opening a gap, and transportation and construction are possible.
(2) Furthermore, even in the case of vertical lines, by passing two vertical lines through the adjacent uneven parts of the horizontal line at the left and right ends of the wire mesh, a four-sided frame is formed by the adjacent two lines, and transported without shifting the wire. Construction becomes possible.
(3) Moreover, since the vertical line and the horizontal line are not fixed and are in a rotatable state, the lattice can be deformed from a rectangle to a parallelogram, and can be applied to an inclined land.
(4) Depending on the size of the wire mesh, the grid area can be reduced by passing horizontal and vertical lines through the adjacent concave and convex portions in the middle as well, and the strength of the fence is improved and the invasion of small animals. The effect which can prevent more reliably increases.
As described above, according to the present invention, a fence made of a wire mesh using a crimped wire rod can be freely deformed while maintaining a parallelogram with a gradient in a range of 0 ° to about 30 °, and can be freely connected to a column / body edge. Because it can be installed freely, it can be installed on flat grounds, and can be easily installed at any site at any angle, and the crimp wire mesh from production to packing, transportation, and construction In handling, since the vertical and horizontal lines are stably knitted, there is no deviation, and handling of the fence becomes easy and the workability is improved.
(6) Moreover, according to the present invention, a deviation of 1.5 pitches or 2.5 pitches as compared with the conventional configuration in which a pair of horizontal lines of two or more lines is installed in the underground with a space in the vertical direction. Alternatively, it is sufficient to arrange at least three underground horizontal lines in a form in which these pitch deviations are mixed, so that the number of horizontal lines in the underground part can be reduced and economically arranged. Since the horizontal lines of the portions are provided at a small pitch, not only the invasion of small animals but also the effect of reliably preventing digging directly under the fence of animals such as wild boars or dogs can be obtained.
Moreover, even if each horizontal line is embedded in the underground part, since it is an underground part, the rigidity is increased and it is also connected to the adjacent horizontal line that engages with the vertical line. can get.
In addition, since at least three horizontal lines embedded in the underground part and vertical lines engaged with the horizontal line are held in a stable state, the horizontal lines in the middle part are also stable. It is possible to reliably prevent the invasion of animals.
If the arrangement pitch of the horizontal lines embedded in the underground part is 3.5 pitches or more, the engagement with each vertical line becomes weak, the horizontal lines become loose and easy to come out, and it becomes difficult to carry the fence body.
Further, as in the third aspect of the invention, when 1.5 pitch deviation or 2.5 pitch deviation is mixed, the horizontal line arrangement in the underground portion is reduced as compared with the horizontal line arrangement of 1, 5 pitch deviation. It is also possible to prevent the digging of animals from being infiltrated more densely than in the case of a horizontal line shifted by 2.5 pitches.

    Next, the present invention will be described in detail based on the illustrated embodiment.

As shown in FIGS. 1 to 4, the fence main body (a metal mesh using crimped wire rods) 1 is configured by knitting a plurality of vertical lines 2 and horizontal lines 3 in a lattice shape. Each wire rod of the vertical line 2 and the horizontal line 3 is a wavy wire rod having a concave portion 4 and a convex portion 5, and as a wire mesh knitted by arranging the vertical line 2 and the horizontal wire 3 made of this wire rod in a predetermined mesh. It is configured. In FIG. 1, the vertical lines 2 on both sides constitute both sides of the fence body 1, the uppermost horizontal line 3 and the lower horizontal line 3 constitute the upper and lower sides of the fence body 1, and the vertical lines 2 on both sides. A plurality of vertical lines 2 and horizontal lines 3 are arranged inside a rectangular frame surrounded by the uppermost part and the lower horizontal line 3 and are knitted at a predetermined pitch and knitted at a predetermined pitch. It is configured as a wire mesh with a large number of horizontal lines.
A large number of horizontal lines 3c at the lower end portion are provided with a horizontal line group 13a for embedding in which the horizontal line 3c consisting of a single line is embedded in the underground portion, and are arranged on the upper side in the vicinity of the ground surface. A horizontal line group 13b at the shore including the horizontal line 3 is provided.

  The vertical line 2a constituting both sides of the fence body 1 and the horizontal line 3a constituting the uppermost part and the lower part are respectively passed through the adjacent corrugated uneven parts of the opposite vertical line 2a and horizontal line 3a. .

2 and 3, the concave portion 4 and the convex portion 5 of the two side vertical lines 2 a of the fence body 1 are engaged with the convex portion 5 and the concave portion 4 of the lower horizontal line 3 a at right angles. . In this way, a set of two or more sets of side vertical lines 2a and lower horizontal lines 3a are intertwined to form a four-sided frame 6, which is knitted so as not to deviate from each other. By forming such a four-sided frame 6 on both sides of the fence body 1, the four rectangular sides of the fence body 1 are stably assembled. Adjacent side vertical lines 2a and lower horizontal lines 3a are knitted so as to be entangled with adjacent convex portions 5 and concave portions 4 of the counterpart wire material by arranging the corrugated uneven portions by a half pitch. The side vertical line 2a and the lower horizontal line 3a may be three or more as long as at least two or more are knitted into the adjacent convex part 5 and concave part 4, but are ideal. Two to four are desirable. In the form shown in the figure, the upper end portion is a set of three horizontal lines 3, and the middle portion and the lower portion are a set of two horizontal lines 3.
Further, on the lower end side, the horizontal line 3c consisting of a single line is shifted by 1, 5 pitches from the waveform of the vertical line 2 (2a, 2b) (the form shown or omitted, but 2.5 pitches). Are arranged alternately and knitted so as to embrace each vertical line 2 from the front and back.
Although not shown, the horizontal line 3c on the lower end side may be provided so that a misalignment arrangement of 1, 5 pitches and a misalignment arrangement of 2.5 pitches are mixed.
A fence of an animal such as a badger, a frog, a dog, or a wild boar is formed by embedding a horizontal line group 13a and a horizontal line group 13b embedded in the ground with a horizontal line 3c between the main lines spaced vertically. It is designed to prevent digging.
The embedding horizontal line group 13a embedded in the underground part is provided with at least three horizontal lines 3c, for example, three to five horizontal lines 3c.
In addition, the horizontal line 3c is provided on the ground surface side in the vicinity of the ground surface, so that digging of the ground surface directly below the fence main body by animals is prevented.

Three sides of the upper end of the fence body 1 and both left and right sides, two sets of both side vertical lines 2a located in the lower part away from the lower end, and upper and lower portions of three sets of one or two sets A plurality of intermediate vertical lines 2b and intermediate horizontal lines 3b are knitted on the inner side of the horizontal line 3a. In the figure, the intermediate horizontal line 3b forms a set of two vertically adjacent ones, and is arranged in a plurality of stages at intervals in the vertical direction. Between the concave portion 4 and the convex portion 5 adjacent to each other. In this way, a set of three upper end horizontal lines 3b or two sets of intermediate horizontal lines 3b and side vertical lines 2a are intertwined to form a four-sided frame 6a. The horizontal part 3b is not stably incorporated and displaced. In particular, even if the set of two intermediate horizontal lines 3b are spaced apart in the vertical direction, both ends are firmly and stably supported by the side vertical lines 2a. The intermediate portion horizontal line 3b may further increase or decrease the number of wires, and in either case, the end portion is stably locked by the adjacent concave portion 4 and convex portion 5 of the pair of both side vertical lines 2a. The
As long as the pitches of the corrugations of the vertical line 2 and the horizontal line 3 are the same, the diameters of the vertical line and the horizontal line may be different.

The plurality of intermediate portion vertical lines 2b are provided extending in the vertical direction by engaging between the concave portions 4 and the convex portions 5 adjacent to each other in the horizontal direction of a set of two intermediate portion horizontal lines 3b provided in multiple stages. Furthermore, the upper and lower end portions of the intermediate portion vertical line 2b are disposed between the concave portion 4 and the convex portion 5 adjacent to each other in the horizontal direction of the pair of upper and lower horizontal lines 3a. Thus, the fence main body 1 is stably knitted by supporting the intermediate part vertical line 2b so as not to slip between the pair of intermediate part horizontal line 3b and the upper and lower part horizontal line 3a. The interval between the plurality of intermediate portion vertical lines 2b arranged in the horizontal direction is arbitrary, but the intermediate portion horizontal lines 3b may be provided at an interval of 3 pitches or more between the concave portion 4 and the convex portion 5. Moreover, while the lower end part of the both-sides vertical line 2a and the intermediate | middle part vertical line 2b is extended below the lower horizontal line 3a of 2 sets of the lowest step, and forms the vertical line part of a ground part, The vertical line part of the underground part is formed.
The horizontal line 3c of the single line is arrange | positioned so that it may become the front and back alternately with respect to each vertical line in the vertical line part of a ground part, and the vertical line part of an embedding part.

  The diameters of the vertical lines 2 and the horizontal lines 3 are preferably provided below the depth (h) of the corrugated recess 4. With this configuration, the vertical line 2 and the horizontal line 3 are accommodated in and engaged with the corrugated recesses 4 of the mating vertical line 2 and horizontal line 3, so that it is difficult to escape from the recess 4 and the knitting is stable. Aesthetics are also improved. The vertical line 2 and the horizontal line 3 are, for example, a diameter of 4Φ mm as a standard, and the wire diameter (d), the depth (h) and the pitch (p) of the corrugated recesses are, for example, 2: 4: 5, In order to reduce the out-of-plane deformation of the fence, it is preferable to use the wire diameter (d), the depth (h) of the corrugated recess (h), and the pitch (p) appropriately adjusted. The vertical line 2 and the horizontal line 3 that engage with each other in the corrugated uneven portion do not shift in the axial direction of the mating wire that engages with each other, and the depth (h ) And the pitch (p) are set, the vertical line 2 and the horizontal line 3 are rotatable with respect to each other. That is, it can be smoothly deformed while maintaining a parallelogram with the intersection of the vertical line 2 and the horizontal line 3 as a fulcrum.

  When the fence body 1 is installed on a flat ground, it can be arranged in a rectangular state in which the vertical lines 2 and the horizontal lines 3 intersect at right angles as shown in FIG. 4 (a). By moving both sides of the fence body 1 upside down as shown in (b), the fence body 1 is held in a parallelogram, that is, the vertical line 2 is held in a vertically oriented state. Thus, the upper and lower portions of the fence body 1 can be inclined. In this case, the depth (h) and pitch (p) of the concave portion 4 and the convex portion 5 are set with a margin with respect to the wire diameter so that the vertical line 2 and the horizontal line 3 are rotatable. Accordingly, the concave portion 4 and the convex portion 5 of both wires can be smoothly deformed from the rectangular state to the inclined state by rotating while maintaining the engagement.

  Moreover, although the vertical line 2 and the horizontal line 3 are arranged with appropriate gaps in the vertical and horizontal directions, the upper end portion and the lower portion and the left and right portions of the fence body 1 are a set of two vertical lines. 2 and the horizontal line 3 are stably assembled by engaging the adjacent corrugated recesses 4 and protrusions 5, so that the entire wire is stable and will not be displaced. Therefore, the problem that the vertical and horizontal lines collapse due to handling from production to packing, transportation, and construction is solved.

  As shown in FIG. 5, the fence body 1 is attached to pillars 8 erected on the ground 7 at predetermined intervals to constitute a fence 10. Referring to FIGS. 5 to 12, the support column 8 is a steel tube support column having a circular cross section, and the lower end portion is disposed in a steel tube foundation 15 that is embedded and fixed in the ground 7, and the steel tube foundation 15 is filled with concrete or Buried in mortar. An upper trunk edge 12 made of an angle member is installed between adjacent struts 8, and the upper part of the fence body 1 is fixed to the upper trunk edge 12. Both side portions of the fence body 1 are fixed to the support column 1 using fixing brackets.

If the structure of each part is demonstrated in order, as shown to Fig.11 (a) (b), the perpendicular | vertical part of the upper trunk | rim edge 12 which consists of an angle material will contact | abut to the support | pillar 8, and the volt | bolt 14 penetrated through these will be carried out. And it is attached to the support | pillar 8 with the nut screwed into this.
As shown in FIG. 9, a set of three upper horizontal lines 3a of the fence body 1 is applied to the inner side surface of the vertical portion of the upper trunk edge 12, and a metal mesh mounting bracket between adjacent intermediate vertical lines 2b. 16, and is fixed to the upper trunk edge 12 via a bolt 17 that penetrates the wire mesh fitting 16 and a nut screwed into the bolt 17. Further, as shown in FIGS. 10D and 10E, the end of the upper trunk edge 12 having a predetermined length is overlapped with the end of one trunk edge having a stepped portion, and is fixed by a fixing bolt 18. Thus, the fence is constructed continuously over the installation length.

The intermediate portion horizontal line 2b provided in multiple stages in a set of two is fixed to the support column 8 using the metal fitting shown in FIG. 5F. As shown in FIGS. 12 (a) and 12 (b) showing the details of the metal fitting of the F part in FIG. 5, a rectangular steel support plate 16 is disposed between the support column 8 and the fence body 1, and The end portions of the left and right fence bodies are overlapped with the steel support plate 16 of the steel plate, the end portions of the intermediate horizontal lines 3b of the adjacent fence body 1 and the side vertical lines 2a are applied, It is pressed at the same time. Both ends of the U bolt 30 holding the support column 8 are inserted into the presser fitting 29 and the steel support plate 16, and the nut 31 is fastened so that the steel support plate 16 and the presser fixture 29 are interposed. Thus, both sides of the fence body 1 are fixed to the support column 8.
Thus, by providing the fixing means of the F part of FIG. 5 at intervals in the vertical direction, both side parts of the fence body 1 are fixed to the support column 8. This fixing means can be commonly applied when the fence body 1 is installed on either a flat ground or an inclined ground. When the fence body 1 is fixed to the support column 8, the vertical lines 2 and the single horizontal lines 3c that interfere with the steel pipe foundation 15 at the lower ends (corners) of the left and right sides of each fence body 1 are appropriately cut and removed. Is done. In addition, when not using the steel pipe foundation 15, it is not necessary to cut and remove.
Since the lower end of the vertical line 2 and at least three horizontal lines 3c embedded in the ground of the single line are embedded and fixed in the ground (underground) 7 together with the lower end of the vertical line 2, the horizontal line embedded in the ground Even if a part of 3c is exposed due to animal digging, the exposed span is small, so the bending rigidity is much higher than the horizontal line on the ground surface where the whole is exposed. The position of each horizontal line 3c of the single line at the lower part and the ground part is stable.

  In the fence 10 of the present embodiment, vertical lines 2 and horizontal lines 3 on which corrugated concave and convex portions are formed are arranged in parallel in vertical and horizontal directions, and the vertical lines 2 are concave and convex portions of two or more horizontal lines 3 that are adjacently shifted by a half pitch. Is engaged through. Further, the interval between the vertical lines 2 and the horizontal line 3 is arranged with an appropriate margin to prevent the invasion of animals, and the rectangular fence body 1 is deformed to an appropriate inclination while maintaining a parallelogram. Thus, it is possible to easily cope with flat land and inclined land at the construction site. Moreover, the fence main body 1 is not broken in the knitting of the vertical lines 2 and the horizontal lines 3 even during the manufacturing, packing, transporting, and handling, and the handling and workability are improved. The number of the vertical lines 2b and the horizontal lines 3b in the intermediate portion, the interval between the arrangements, and the like may be changed to suit the installation situation.

  If the pitch of the horizontal line 3c embedded and arranged in the underground part is mixed with 1.5 pitch deviation or 2.5 pitch deviation, the horizontal line of the underground part is compared with the horizontal line arrangement of 1, 5 pitch deviation. It is also possible to reduce the arrangement, and it is possible to prevent the animal from digging in by arranging it more densely than the horizontal line arrangement shifted by 2.5 pitches.

When carrying out the present invention, as shown in FIG. 14, the fence body 1 is symmetrical in the vertical direction as the horizontal line group 13 b at the bottom of the fence body 1 and the horizontal line group 13 a for the underground part, as shown in FIG. 14. The vertical line 2 may be extended upward so that a plurality of single upper horizontal lines 3c are provided so as to meet the standard desired by the client.
Since the fence body in this form is vertically symmetric, it can be either upside down or upside down of the fence body, so even if it is placed upside down or incorrectly placed, it will be in the correct installation state. Easy installation and no risk of misplacement.
Other than this form, although not shown in the drawings, the height of the fence may be appropriately set so as to conform to the standard desired by the owner. It may be stretched with an interval in the vertical direction.
