Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence structure which can be maintained in a snowy area without causing deformation or damage even when the snow pressure is large.

[0002]

2. Description of the Related Art For example, various fence structures have been used as boundaries for preventing animals from entering an expressway, partitioning sidewalks from roads, or as protective walls for construction sites or factories. As a method of constructing a fence structure of this type, it is common to fix both ends of the fence to a pillar member that is erected at required intervals at the construction site and stretch the fence.

Conventionally, a fence structure is provided with, for example, a frame at the edge of a rhombus-shaped wire mesh fence to be fixedly connected to the column, or a furring edge is provided at the upper and lower ends of the wire mesh to form the furrow with the pillar. The type is mainly connected to. With a frame, it is possible to connect both ends of this frame in the direction of the front to the pillar with bolts and nuts, and even with a furring edge, both ends of this furrow in the direction of the front are fixedly connected to the pillar. The construction is done.

[0004]

However, in the case where the diamond-shaped wire net is used, the wire net may be deformed or torn due to snow pressure because of its large resistance to snow during snowfall. In particular, diamond-shaped wire mesh cannot stand on its own, so it is necessary to equip both upper and lower ends with thick furring strips.
The load applied to the wire net will affect the upper furring strip.
Also, the larger the furring strip, the greater its influence. Therefore, the wire net, the furring strip, or the support pillar is damaged or collapsed, and the durability is reduced. Further, in the case of a fence-like net composed of horizontal members and vertical members, the resistance is relatively small, so that the deformation of the fence can be prevented to some extent, but if a thick furring strip is provided on the upper and lower sides, the deformation still occurs.

As described above, since the conventional fence structure uses the diamond-shaped wire mesh and the thick furring strip, it may be damaged by snow pressure, and the influence of the snow pressure on the sinking force cannot be ignored.

[0006] Further, there is a risk that the animal cannot be prevented from entering the highway and the like, and that the animal interferes with the driving of a running vehicle or is involved in a traffic accident.

[0007] It is an object of the present invention to provide a fence structure which is not deformed or damaged even when snow pressure or the like is applied, and which is capable of maintaining good maintenance without being affected by a sinking force.

[0008]

(11) The pillar is formed in a tubular shape, and a reinforcing body having a cross-shaped cross section is housed and arranged inside the pillar.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a fence structure in which a fence body composed of a vertical member and a horizontal member is arranged between a plurality of pillars erected on a foundation, and at least an upper side of the pillars. Between the parts, the wire rope is connected along the side of the pillar facing the road slope or slope, that is, the side where a large amount of snow pressure is applied, and the fence body is fixed by connecting the pillar and the wire rope. It was done. That is, along the side where a large amount of snow pressure is applied, such as the side where the support column faces the slope or slope of the road, one wire rope is laid on the upper stage or a plurality of wire ropes is extended on the upper and lower sides. And the fence body is fixed and held to the pillar.

By placing the wire rope in a tensioned state and arranging it between the columns, the fence body can be stably held. By holding the fence body up and down and its intermediate position by the wire rope, it is possible to reduce the accumulation of snow in the snowy area and to greatly suppress the sinking force due to the snow, without requiring a thick furring strip.

A fixing seat fixed to one surface of the support, a tightening tool having an arc portion for holding the wire rope, and a bolt penetrating the support and the fixing tool and the tightening tool.
If the nut that is screwed to this is provided, the wire rope can be easily fixed to the column by screwing with the bolt and the nut, and on-site construction can be simplified. At this time, a tightening tool in which the fixing seat and the tightening tool are integrally formed, that is, one in which a long plate is folded back instead of the fixing tool and the tightening tool and an insertion portion for inserting the wire rope is formed in the folding back portion is used. You can also

Further, a fixture having a substantially U-shaped cross section can be arranged between the columns to hold the wire rope and the lateral member of the fence body. That is, the wire rope and the lateral member of the fence body are inserted into a fixture having a substantially U-shaped cross section and can be restrained from each other by bolts and nuts that contract the fixture. Thus, the lateral member can be restrained and fixed at any position of the wire rope, and the number of fixing devices can be set arbitrarily.

Therefore, it is possible to obtain the fixing structure of the wire rope and the fence body according to the construction conditions at the site.

It is also possible to provide an intermediate fixing tool for fixing the ends of adjacent fences to the support in a state where the ends of the fences overlap each other.

That is, the intermediate fixing member has a large number of substantially mountain-shaped projections formed on one surface side thereof, and a pair of restraint plates capable of sandwiching the vertical members of the overlapping fence body so as to face each other from the front and rear, respectively. A connecting tool for connecting and fixing the restraint plate to the pillar may be provided. As a connecting tool, U which penetrates the left and right end portions of the pair of restraint plates while hugging the support column
It is possible to use, for example, a bolt and a nut that is screwed at both ends of the U bolt, and if the ends of the fence body can be constrained to the column by screwing with the U bolt and the nut, The ends of the two fence bodies can be reliably restrained and connected.

In particular, the cut portions having a substantially V-shaped cross-section formed between the plurality of substantially mountain-shaped projections formed on the restraint plate are separated from each other by vertical members of the fence body at the cut portions. By having a size and a shape that can be sandwiched, it is possible to obtain a strong fixation capable of withstanding the tensile force applied to the fence body.

Further, a large number of rectangular trapezoids having the same shape and the same size are adjacent to each other on the restraint plate to form substantially mountain-shaped protrusions in the vertical and horizontal directions, and the protrusions having the substantially mountain shape are formed between the protrusions. The vertical member of the fence body is fixed at an optimal position by making it so that the vertical member of the fence body can be sandwiched in the shape of a V-shaped notch formed in the cross section of the fence member in an isolated manner. As a result, a strong fixation that can withstand the tensile force applied to the fence body can be obtained.

Further, it is preferable that the end column and the wire rope are connected so that the tension force can be adjusted.

For example, a spectacle bolt is arranged on the end column, and a tension force is formed between the spectacle bolt and the end of the wire rope whose both ends are loop-shaped, which are formed at both ends. The end support column and the wire rope can be connected to each other via an adjustment tool turnbuckle that allows adjustment of the. Therefore, the tension of the wire rope can be adjusted by the turnbuckle.

Further, it is preferable to dispose a brace capable of adjusting a tension force between the adjacent end columns.

That is, when the total length of the fence structure is long, two fence structures with adjusted wire ropes are arranged adjacently between the left and right end struts, and between the two adjacent fence structures. Fixing metal fittings are arranged on the upper and lower parts of the end strut at the right end and the end strut at the left end respectively, and the fixing metal fittings have adjusting tools for adjusting tension in the middle part and hooks at both ends. By arranging the braces having the connecting portions in the shape of braces, the two fence structures can be connected in series to form one fence structure. Further, when the total length of the fence structure is long, a plurality of fence structures can be similarly connected in series to form a fence structure having a predetermined length.

As described above, by arranging braces in a bracing manner between the adjacent end struts at the right end and the end struts at the left end where the wire rope is not present, one direction applied to each end strut. The durability of the fence can be improved by canceling the tension of the wire rope from.

Further, when the tension of the brace is relaxed after the construction, the tension can be easily adjusted by the adjusting tool at any time.

With this structure, it is possible to provide a fence structure having excellent durability, no matter how long the total length of the fence structure is.

A tubular wire guide for inserting and holding the wire rope may be attached to the intermediate support. That is, when the wire rope is stretched between the left and right end columns, the contact structure of the wire rope with respect to the intermediate column is
At the abutting point between the intermediate support column and the wire rope that exists between the left and right end support columns, fix the tubular wire guide that inserts the wire rope on the side surface of the intermediate support column, and insert the wire rope into the wire guide. It is configured to be inserted and held.

By using such a wire guide,
It is possible to prevent the wire rope from being sandwiched between the intermediate strut and the vertical member of the fence body and restrained, and to easily perform the tensioning work again when the wire rope becomes loose after the fence construction.

Further, instead of the end struts made of H-shaped steel or the intermediate struts made of a solid circular pipe, the struts are formed in a tubular shape, and a reinforcing body having a cross-shaped cross section is housed inside the struts. can do.

As described above, by using the other end stanchions in which the reinforcing body having a cross-shaped cross section is housed inside the pipe, that is, the reinforced square struts and the reinforced round struts, the strength of the struts against bending is significantly improved. Since the outer diameter of the support pillar can be made thin and the wall thickness of the support pillar can be made thin, the cost can be reduced.

Further, when the fence body is arranged on the column and the wire rope, it is preferable to bury the lower part of the fence body in the ground.

With this structure, it is possible to prevent small animals from entering through the gap generated between the lower edge of the fence and the ground. Further, even if an animal digs a hole in the ground and tries to enter from there, it is impossible because the lower part of the fence body exists in the ground, and the invasion can be prevented. Further, since the vertical member of the fence body can be pierced into the ground, it is difficult to receive the sinking force and damage to the fence body can be prevented.

Further, it is preferable to form a vertically long grid having a predetermined vertical width on the upper part of the fence body so as to prevent clue of animals or the like.

That is, a fence body provided with a clue prevention portion by forming a vertically long grid having a predetermined vertical width at the upper part of the fence body with a vertical interval between lateral members to prevent clue of animals and the like is used. Then, even if the animal climbing the fence body tries to get over the fence and tries to reach the end, there is no horizontal member at the top of the fence, so it is impossible to use it as a clue,
Animals can be prevented from entering the fence. Therefore, for example, it is possible to eliminate the risk of an animal invading a highway, obstructing a running vehicle, or being involved in a traffic accident.

It is also possible to extend the support column in the upper direction to form an extension portion, and dispose the ride-over preventing body on the extension portion. That is, by disposing an anti-climbing body using a wire net, an anti-climbing body using an iron wire, and an anti-trapping body using a lattice net, it is possible to prevent an animal from climbing over the fence from entering the fence. Even in this case, as described above, for example, it is possible to eliminate the risk of an animal intruding into a highway, obstructing a running vehicle, or being involved in a traffic accident.

In this embodiment, the example in which the snow pressure is applied to the pillar has been described as the side facing the road slope or the slope, but the snow pressure surface may change depending on the fence installation location.

Therefore, it is desirable to appropriately set the surface on which the wire rope is installed according to the location where the fence is installed.

It is composed of a nut 5d screwed to c.
As shown in FIG. 6, the wire rope 3a has one end connected to an eye guard 1b provided at the upper end of the end strut 1 and is stretched in tension with the end strut 1 on the other end side. Then, the wire rope 3a is inserted between the tightening tool 5b and the fixed seat 5a as shown in FIG. The wire ropes 3b and 3c are also connected and fixed to the end column 1 and the intermediate column 2 by the same mounting structure. (Refer to FIG. 3) As another example of the fixing device for fixing the wire rope 3a to the intermediate support column 2, as shown in FIG. 7, the fixing seat and the tightening device can be integrally formed. . Specifically, it is a tightening tool 5b 'in which the long plate attached to the intermediate support column is folded back and an insertion portion for inserting the wire rope 3a is formed in the folding portion. The fixing structure for fixing the wire rope 3a to the intermediate support column 2 in this case is a tightening tool 5b ', a bolt 5c penetrating the intermediate supporting post 2'and being inserted from the front side and penetrating the tightening tool 5b', and this bolt 5c. 5d screwed to
It will consist of and.

The wire ropes 3a, 3b, 3c may be fixed to the fence body 4 without being connected and fixed to the intermediate column 2.

FIG. 8 shows the details of the portion A enclosed by the broken line in FIG. 1, showing the structure for fixing the fence body 4 to the intermediate support column 2, where (a) is a front view and (b) is the same figure. It is sectional drawing by the AA arrow of (a).

The fences 4 adjacent to each other are fixed to the intermediate column 2 in a state where the ends of the fences 4 overlap with each other, and a pair of restraint plates 6a and 6a are arranged so as to sandwich the two fences 4 respectively. The U-bolt 6d and the nut 6e screwed onto the U-bolt 6d constitute an intermediate fixture. That is, the U-bolt 6d is arranged so as to embrace the intermediate support 2, and the restraint plates 6a and 6a are used to remove the U-bolt 6d.
The two fence bodies 4 are fixed to the intermediate column 2 by sandwiching the ends of the fence bodies 4 and screwing the U bolt 6d and the nut 6e. The restraint plates 6a, 6
As shown in the enlarged view surrounded by a circular frame in FIG. 8B, a large number of substantially mountain-shaped projections are formed on one surface side of a, and the end portions of the two fence bodies 4 are securely restrained. So that they can be connected.

At this time, instead of the restraint plates 6a, 6a, the restraint plates 6b, 6 as shown in FIG. 9 and FIG.
b, or restraint plates 6c, 6 as shown in FIG.
c can be used.

First, the restraint plate 6 according to the first modification.
An example of using b and 6b is shown in FIG.

The restraint plates 6b, 6b are formed by expanding the notched portions having a substantially V-shaped cross-section formed between the plurality of substantially mountain-shaped protrusions of the restraint plates 6a, 6a (FIG. 8) described above. The size and shape are such that the vertical members 4a of the fence body 4 can be sandwiched in such a manner that they are separated one by one.

With the constraining plates 6b and 6b having such a structure, the vertical members 4a of the fence body 4 can be sandwiched one by one in a separated manner, and a stronger fixation capable of withstanding the tensile force applied to the fence body 4 can be obtained. .

Next, a restraint plate 6 according to a second modification.
Describing c, as shown in FIG. 11, the constraining plates 6c, 6c have rectangular trapezoids of the same shape and the same size instead of the substantially mountain-shaped projections formed by the constraining plates 6a, 6a. A large number of adjacent protrusions are formed in a substantially mountain shape in both the vertical and horizontal directions.

In the constraining plates 6c, 6c having such a structure, the notched portions formed between the substantially mountain-shaped projections and having a substantially V-shaped cross section can be sandwiched in such a manner that the vertical members of the fence body are isolated one by one. Because of the large size and shape, the vertical member of the fence body can be fixed at an optimum position, and a strong fixation that can withstand the tensile force applied to the fence body can be obtained.

FIG. 12 shows a structure for fixing the fence body 4 to the wire rope 3a, in which (a) is a perspective view of a main part,
(B) is a sectional view of a main part.

The fence body 4 is fixed to the intermediate support column 2 by the fixing structure shown in FIG. 8 and also fixed to the wire rope 3a by the fixing tool 7. The fixture 7 has a substantially inverted U-shaped cross section as shown in FIG.
The horizontal member 4b running along the wire rope 3a can be held together with the wire rope 3a. Then, holes 7a and 7b are opened in the fixture 7, and bolts 8 are passed through these holes 7a and 7b and nuts 8a are screwed into the bolts 8 to strongly tighten the fixture 7, As shown in (b), the horizontal member 4b can be integrally fixed to the wire rope 3a. The same applies to the connection structure between the lower wire ropes 3b and 3c and the lateral member 4b of the fence body 4.

In the above structure, the fence structure is constructed by the following procedure.

First, the foundations 1a and 2a are formed in the ground, and the end columns 1 and the intermediate columns 2 are erected on each of them. A plurality of intermediate support columns 2 are arranged at intervals with the end support columns 1 shown in FIG. 1, and the end support columns 1 are provided at the right end.
The same structure is installed upright.

After the standing work of the end support column 1 and the intermediate support column 2, the wire ropes 3a, 3b, 3c are stretched around the end support column 1 and the intermediate support column 2. At this time, similarly to the example of the wire rope 3a shown in FIG. 6, one end of the wire rope 3a is connected to the end support column 1 arranged at the right end by a winding grip and an eye guard 1b so as to be tensioned. . The construction of the wire ropes 3b and 3c arranged in the lower stage is similarly performed. Then, as shown in FIGS. 4 and 5, for the intermediate column 2, the wire rope 3a is fixed to the intermediate column 2 by the fixing seat 5a, the tightening tool 5b, the bolt 5c, and the nut 5d. In addition,
By performing the same construction on the wire ropes 3b, 3c, it is possible to stretch the three wire ropes 3a, 3b, 3c with respect to the array of the end support 1 and the intermediate support 2.

At this time, the tightening tool 5b 'shown in FIG. 7 is used in place of the fixing seat 5a and the tightening tool 5b for fixing the wire rope 3a to the intermediate column 2.
Wire rope 3a by b ', bolt 5c, nut 5d
Can also be fixed to the intermediate column 2. By performing the same construction on the wire ropes 3b and 3c, the three wire ropes 3a, 3b and 3c can be stretched with respect to the arrangement of the end support 1 and the intermediate support 2.

After the wire ropes 3a, 3b, 3c have been constructed, the two fence bodies 4 are attached to the front surface of the intermediate support column 2 so as to overlap each other. As shown in FIG. 8, this attachment work is performed using the restraint plates 6a, 6a, the U bolts 6d, and the nuts 6e having minute irregularities.

That is, the front ends of the two fence bodies 4 are overlapped with each other and arranged on the front side of the intermediate column 2, and the two fence bodies 4 are sandwiched by the restraint plates 6a and 6a, and the U-bolt is used. The end portion of the fence body 4 is fixed to the intermediate support column 2 by tightening with 6d and the nut 6e.

At this time, the constraining plates 6a, 6 having the above structure
Instead of a, the above-mentioned restraint plates 6b, 6b (see FIG.
Reference) or restraint plates 6c, 6c (see FIG. 11)
Can be used. In that case, in the construction for attaching the two fence bodies 4 to the intermediate support column 2 in FIG. 8, it is sufficient to replace the restraint plates 6a and 6a with the restraint plates 6b and 6b and the restraint plates 6c and 6c, respectively. 9 shows an example of construction using the restraint plates 6b, 6b.

With this construction, the wire rope 3
While a, 3b, 3c are fixed to the end support 1 and the intermediate support 2, the fence body 4 is fixed to the intermediate support by the U bolt 6d, the restraint plates 6a, 6a and the nut 6e, and the wire ropes 3a, 3b, The lateral member 4b of the fence body 4 is fixed to the 3c via the fixture 7 (see FIG. 1).
2).

In this way, the end support 1 and the intermediate support 2 are provided.
The fence body 4 is fixed to, and the fence body 4 on the left side in FIG.

In the fence structure thus constructed, since the fence body 4 is supported by the wire ropes 3a, 3b, 3c, slope snow pressure, passive snow pressure, etc. can be applied to the entire fence body 4 and the end columns. It can be received by the whole of 1 and the intermediate support 2. That is, since the fence body 4 is located on the inclined surface side with respect to the end column 1 and the intermediate column 2, the fence body 4 moves from the wire rope 3 to the wire rope 3 when snow pressure is applied.
It can be distributed and supported by being transmitted to the end column 1 and the intermediate column 2 via a, 3b and 3c. Therefore, it is not necessary to provide a thick furring strip as in the conventional case, and the strength can be increased as compared with the case of using the conventional diamond-shaped wire net, so that the distance between the end support column 1, the intermediate support column 2 and the intermediate support columns is wide. Therefore, the cost can be reduced.

Further, since a thick furring strip is not required, the cross-sectional area of the fence body 4 can be reduced to half or less as compared with the conventional one. Therefore, it is possible to minimize the influence of the sinking force due to the accumulation of snow.

Further, since the vertical members 4a are arranged at intervals of 50 mm, it is possible to promote the passage of snow, and it is possible to prevent the fence body 4 from being deformed or damaged by snow pressure as compared with the case of the rhombus net. That is, even when installed in a snowy area, it is easy for snow to escape from the slits between the vertical members 4a and snow clogging is reduced, and the snow pressure composed of slope snow pressure and passive snow pressure due to snowfall and the sinking force caused by the accumulated snow It is difficult to receive the snow, and even if all the snow pressure is received, it is dispersed and received by the entire fence body 4, so that the fence body 4 is not deformed.

Further, the end support 1 and the intermediate support 2 which are provided upright.
Since the frontage of the fence body 4 is overlapped and adjusted, even if the end support 1 and the intermediate support 2 are slightly displaced, they can be easily attached and the workability can be improved.

In the above embodiments, an example in which a fence structure is installed along a slope such as a road has been described, but the invention can also be applied to protective fences at airports, factories and the like.

Another embodiment of the end column 1 and the intermediate column 2 described above will be described.

In place of the end struts 1 made of H-shaped steel and the solid or simply round pipe-shaped intermediate struts 2 in the above-mentioned embodiments, the reinforced square struts 10 and the reinforced round struts provided with the reinforcing bodies 11 are provided. Posts 12 can be used.

That is, as shown in FIG. 13, the reinforcing type square column 10 has a reinforcing body 1 having a cross-shaped cross section inside a substantially rectangular pipe.
1 is accommodated and arranged. The reinforcing type round column 12 is such that a reinforcing body 13 having a cross-shaped cross section is also accommodated and disposed inside a circular pipe as shown in FIG.

The cross-shaped reinforcing members 11 and 13 are made of metal such as iron and aluminum. The reinforcing members 11 and 13 formed in a cross shape from the beginning may be used, or as shown in FIG. Alternatively, the reinforcing body 14 may be formed by using two "L" -shaped angle members and welding the ridge lines of the bent portions to each other to form a cross shape.

With this structure, it is possible to increase the cross-sectional modulus of the column and remarkably improve the bending strength of the column.

Therefore, it is possible to reduce the cost because the outer diameter of the column can be made thin and the wall thickness of the column can be made thin.

Next, another embodiment for fixing the above-mentioned wire rope 3a to the end support 1 will be described.

In this embodiment, the end support 1 and the wire rope 3a are connected to each other so that the tension force can be adjusted. Specifically, as shown in FIG. A turnbuckle 18 is fixed between the eyeglass bolt 15 and the wire rope 3a so that the tension force can be adjusted. In the figure, 16 is a nut for fixing the spectacle bolt 15 to the end support 1.
A washer 7 is interposed between the nut 16 and the end support 1. Although the one shown in the drawing is on the left end side of the wire rope 3a, the same applies to the right end.

With such a structure, the tension of the wire rope 3a can be adjusted by the turnbuckle 18, and when the wire rope 3a is tensioned, it can be tensioned with appropriate tension. It will be easy. In addition, when the wire rope 3a becomes loose after construction,
At any time, the turnbuckle 18 can easily return to a tension state.

Therefore, for example, even when the wire ropes 3b and 3c are loosened after the construction of the fence, the work of returning the wire ropes 3b and 3c to the tensioned state again can be easily performed.

Further, the same function as that of the wire guide 22 can be given to the above-mentioned restraint plates 6a, 6a.

That is, in the fixing structure of the fence body 4 to the intermediate column 2 shown in FIG. 8, instead of the pair of restraint plates 6a, 6a arranged so as to sandwich the two fence bodies 4 respectively, FIG. The pair of restraint plates 6a 'and 6a as shown is used.

This extends the upper and lower parts of the restraint plate 6a located on the side of the intermediate support shown in FIG. 8 and bends them at right angles to the side of the intermediate support 2 so that the space S for inserting the wire rope is formed between the two bent portions. Is formed.

Then, the wire rope 3b is inserted into the wire rope insertion space S, and the restraint plates 6a ', 6a, the U bolt 6d' and the nut 6e screwed to the U bolt 6d 'constitute an intermediate fixing tool. , U-bolts 6d 'are arranged so as to embrace the intermediate support columns 2', and the ends of the two fence bodies 4 are sandwiched by the restraint plates 6a ', 6a.
The two fence bodies 4 are fixed to the intermediate column 2 by screwing the nut 6e of the U bolt 6d '.

With such a configuration, the wire ropes 3b and 3c arranged between the intermediate support column 2 and the vertical member 4a of the fence body 4 are connected to the intermediate support column 2 and the vertical member 4 of the fence body 4.
It is possible to prevent the wire rope 3a and 3c from being pinched and restrained, and again, when the wire ropes 3b and 3c are loosened after the fence construction, the tensioning work can be easily performed again.

Next, a description will be given of the fence structure to which the animal protection effect is added.

Also, since the lower end of the vertical member 4a remains in the ground, it is possible to prevent animals from entering.

Therefore, it is possible to prevent the animal from entering the fence and eliminate the risk of the animal, for example, entering the highway and obstructing the running vehicle or being involved in a traffic accident. . Moreover, since the vertical member 4a of the fence body 4 is buried in the ground, it is more difficult to receive the sinking force than in the case of the conventional diamond net, and the fence body 4 can be prevented from being damaged.

Further, as a fence body having a further animal protection function, as shown in FIG. 20, a clue prevention portion 23 having a vertically long grid having a predetermined length for preventing clue of animals or the like is provided. Things can be used.

In the clue preventing fence body 4'having such a structure, even if an animal tries to climb over the fence and try to hang his hand (forefoot) at the end, the horizontal member 4a does not exist in the upper portion, and is used as a clue. Since this is impossible, the invasion of animals can be prevented.

Therefore, it is possible to prevent the animal from entering the fence, and eliminate the risk of the animal, for example, entering the highway to obstruct a running vehicle or get involved in a traffic accident. it can.

Further, as another example of the fence to which the animal protection function is added, the configuration shown in FIGS. 21 to 23 can be adopted.

In the structure shown in FIG. 21, the left end support 1, the right end support 1, and the intermediate support 2 are extended upward to form extension portions 25, and the extension portions 25 are prevented from climbing over. That is, the ride-over preventing body 26 by a wire net is provided.

FIG. 22 shows a structure in which an iron wire is used in place of the iron wire net to prevent the ride-over prevention member 27, and FIG.
Is provided.

With such a structure, it is possible to prevent an animal from overcoming from the upper part of the fence and entering the fence. For example, an animal may enter the highway and interfere with a running vehicle. And the risk of getting involved in a traffic accident can be eliminated.
