Description

  The present invention relates to a wild beast protection fence, and more particularly to a wild beast protection fence that can improve corner joint rigidity and fence durability.

  Due to natural destruction such as logging of mountain forests, wild beasts such as moths come down to the mountain villages and eaten and destroy the farm products in the fields. Therefore, by surrounding the field with a wild beast protection fence, the wild beast is prevented from entering the field.

  Such a conventional beast protection fence (a fence entry prevention fence) is disclosed in Patent Document 1. The conventional fence intrusion prevention fence has a plurality of longitudinal steel wires 1 (vertical steel bars) arranged at intervals in the horizontal direction and a plurality of transverse steel wires 2 arranged at intervals in the vertical direction. A fence part F (fence) which is configured in a rectangular shape with (horizontal steel bar) and is located on the ground, and a buried part 3 which is formed of a vertical steel wire 1 projecting downward from the fence part F and buried in the ground It consists of In the fence part F, the horizontal steel wires 2 are arranged at a wide interval in the upper half where the wrinkles do not jump and the horizontal steel wires 2 are arranged at a narrow interval in the remaining lower half. As a result, it is possible to reliably prevent the fence from jumping over the fence entry barrier and digging the ground and entering the field.

  Further, Patent Document 2 discloses a conventional intrusion in which a slanted portion that is inclined outwardly, that is, a so-called creeping 16 is provided at the upper end of the rhombus metal mesh 11 by bending the upper end of the rhombus metal mesh 11 (fence) configured in a rectangular shape outward. A prevention fence (beast guard fence) is disclosed. The creeping 16 gives a feeling of pressure that wild animals such as spiders cannot jump over, so that jumping of wild animals such as spiders can be prevented. Therefore, it is possible to prevent a wild beast such as a spider trying to jump over the intrusion prevention fence from colliding with the intrusion prevention fence and damaging the intrusion prevention fence.

Utility model registration No. 3145084 (Fig. 1 etc.) Japanese Patent Application Laid-Open No. 2004-92388 (FIGS. 1 and 2 etc.)

  However, in the above-mentioned conventional beast guard fence, when the upper end of the fence is bent outward to form a flip, if a pair of fences are arranged side by side, a gap is generated between the pair of flips in the corner. To do. If there is a gap between a pair of creeps, the flips will not function effectively, and wild animals such as spiders will collide with the fences trying to jump over the fences, causing damage to the fences.

  In addition, since the vertical steel wires constituting the sides of the pair of fences are simply connected by the binding wires at the corner, one fence is centered on the vertical steel wires constituting the sides of one fence of the pair of fences. There is a problem that the corner may be rattled due to rotation with respect to the other fence.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a wildlife protection fence that can improve corner joint rigidity and fence durability.

  In order to achieve this object, the beast guard fence according to claim 1 is provided with a plurality of vertical steel bars arranged at predetermined intervals in the horizontal direction and oriented in the vertical direction and arranged at predetermined intervals in the vertical direction. A rectangular fence portion formed in a lattice shape with a plurality of horizontal steel bars oriented in the direction, and a creeping portion extending upward from the upper end of the fence portion and inclined to the outside with respect to the fence portion A fence is provided, and the pair of fences are arranged side by side by connecting the sides of the fence part, and are disposed inside a corner formed by the pair of fences. Reinforcing portions connected to the respective fence portions, and extending upward from the upper ends of the reinforcing portions so as to be inclined to the outside with respect to the reinforcing portions and closing gaps formed between the pair of the endlessly And a corner member having a covering section.

  The wild beast guard fence according to claim 2 is the beast guard fence according to claim 1, wherein an end of the horizontal steel bar is in contact with the vertical steel bar constituting the side of the fence part.

  The wild beast guard fence according to claim 3 is the wild beast guard fence according to claim 1 or 2, wherein the vertical lock part locked to the vertical steel bar, and the horizontal steel bar extending from the vertical lock part. A horizontal locking portion for locking the rod, an arm portion extending from at least one of the vertical locking portion and the horizontal locking portion toward the outside of the fence, and formed on the arm portion of the fence. A holding part for holding a bare electric wire stretched outside, and an electric wire holder made of an insulating member.

  The wildlife guard fence according to claim 4 is the wildlife guard fence according to claim 3, wherein the predetermined interval at which the horizontal steel bars are arranged is set narrower at the lower part of the fence part than at the upper part of the fence part, The electric wire holder is disposed below the fence portion.

  According to the beast guard fence according to claim 1, the fence includes a fence portion that extends upward from an upper end of a fence portion formed in a lattice shape by a plurality of vertical steel bars and a plurality of horizontal steel bars. Therefore, when the side edges of the fence portion are connected and the pair of fences cross each other, the gap is generated between the pair of creeps.

  Here, the corner member includes a reinforcing portion disposed inside a corner formed by a pair of fences, and a closing portion extending upward from the upper end of the reinforcing portion and inclined outward with respect to the reinforcing portion. The corner member reinforcing portion is connected to each of the pair of fence portions, and the corner member closing portion closes a gap formed between the pair of creeping portions, so that the corner joint rigidity can be improved. There is an effect that the durability of the fence can be improved.

  That is, even when a gap is generated between a pair of breaks, the gaps are blocked by the closed portions of the corner members, so that the breaks can function effectively. Therefore, since it is possible to reliably give the wild beast a sense of pressure that it cannot jump over the fence, it is possible to prevent the wild beast from colliding with the fence and damaging the fence, thereby improving the durability of the fence.

  Further, in the corner formed by the pair of fences, the corner member reinforcing portion is connected to each of the pair of fence portions, so the corner angle (the angle at which the pair of fences intersect) is constant by the corner member reinforcing portion. Can be kept in. Therefore, since one fence can be prevented from rotating with respect to the other fence around the vertical steel bar constituting the side of one fence, the corner can be prevented from rattling. The joint rigidity can be improved.

  According to the wildlife guard fence of Claim 2, in addition to the effect which the wildlife guard fence of Claim 1 shows, since the edge part of a horizontal steel bar contact | abuts to the vertical steel bar which comprises the side of a fence part, The end of the steel bar does not protrude from the side of the fence. Therefore, when performing a connecting operation for connecting the sides of a pair of fence sections arranged side by side, the end of the horizontal steel bar does not interfere with the vertical steel bars constituting the sides of the fence section, so the connecting operation is simplified. There is an effect that can be performed.

  According to the wildlife guard fence of Claim 3, in addition to the effect which the wildlife guard fence of Claim 1 or 2 has, it is latched by the horizontal steel bar from the vertical latching part latched by the vertical steel bar. A horizontal locking portion is extended, and a bare electric wire stretched outside the fence is held by an arm portion extending from at least one of the vertical locking portion and the horizontal locking portion toward the outside of the fence. A holding part is formed. Therefore, since the bare wire is stretched outside the fence, the beast can be repulsed by electric shock, while the arm portion is interposed between at least one of the vertical locking portion and the horizontal locking portion and the holding portion. Therefore, the bare electric wire is spaced apart from the vertical steel bar and the horizontal steel bar. Therefore, there is an effect that the bare electric wire can be stretched outside the fence without contacting the vertical steel bar and the horizontal steel bar.

  Furthermore, since the electric wire holder is made of an insulating member, there is an effect that electricity can be prevented from flowing from the holding portion holding the bare electric wire to the vertical locking portion and the horizontal locking portion via the arm portion. Further, since the horizontal locking portion locked to the horizontal steel rod extends from the vertical locking portion locked to the vertical steel rod, the vertical locking portion and the horizontal locking portion are connected to the vertical steel bar and the horizontal steel. When each of the bars is locked, the rotation of the vertical locking part relative to the vertical steel bar is restricted and the rotation of the horizontal locking part relative to the horizontal steel bar is restricted. Therefore, there is an effect that the electric wire holder can be easily and stably locked to the fence.

  According to the wildlife guard fence according to claim 4, in addition to the effect of the wildlife guard fence according to claim 3, the predetermined interval at which the horizontal steel bars are arranged is narrower at the lower part of the fence part than at the upper part of the fence part. Since it is set, there is an effect that small animals can be prevented from entering the fence from the lower part of the fence part. On the other hand, if the lower part of the fence part is set narrower than the upper part of the fence part when the predetermined interval at which the horizontal steel bar is arranged, the use of the horizontal steel bar is less than when it is set narrower in the entire range of the fence part Since the number can be reduced, the fence can be reduced in weight and cost can be reduced. In addition, since the electric wire holder is arranged at the lower part of the fence part, there is an effect that a small animal trying to enter the fence from the lower part of the fence and a wild beast trying to invade by digging the ground can be repulsed by electric shock with a bare electric wire. is there.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Fig.1 (a) is a perspective view of the beast guard fence 1 in 1st Embodiment of this invention, FIG.1 (b) is the side surface of the beast guard fence 1 seen from the Ib direction of Fig.1 (a). FIG. Further, in FIG. 1A, the lateral length of the beast guard fence 1 is partially omitted and illustrated, and a portion embedded in the ground is illustrated by a one-dot chain line. Further, in FIG. 1B, the illustration of the horizontal steel bar 10b is omitted. In addition, the same thing attaches | subjects a code | symbol only to one part, and abbreviate | omits the remaining code | symbol. The same applies to FIGS.

  With reference to FIG. 1, the schematic structure of the beast guard fence 1 is demonstrated. The beast protection fence 1 is a fence that surrounds the field in order to prevent sharks from entering the field. The fence 10 is a rectangular fence 10 that is juxtaposed in the horizontal direction and surrounds the field, and is bound to the fence 10. It is configured to include a support column 2 connected by a wire K and a corner member 20 disposed at a corner of a pair of fences 10 arranged side by side. The pillars 2 are embedded and erected in the ground every 1 to 2 m, and the fence 10 is supported on each of the erected pillars 2 as shown in FIGS. 1 (a) and 1 (b). Accordingly, it is possible to prevent the basket from entering the field by surrounding the field with the plurality of fences 10 and partitioning it from the surroundings.

  The fence 10 and the corner member 20 will be described in detail with reference to FIG. 2 (a) is a front view of the fence 10, FIG. 2 (b) is a side view of the fence 10 viewed from the direction IIb in FIG. 2 (a), and FIG. 2 (c) is a front view of the corner member 20. FIG. 2D is a side view of the corner member 20 as viewed from the direction IId in FIG. In FIG. 2A, illustration of the fence 10 in the length direction is omitted.

  As shown in FIGS. 2 (a) and 2 (b), the fence 10 is a barrier for preventing the fence from entering the field, and has a thickness of 5 mmφ and a length of 1300 mm in the vertical direction. The nineteen vertical steel bars 10a oriented and the eight horizontal steel bars 10b oriented in the lateral direction having a thickness of 5 mmφ and a length of 1800 mm are welded in a grid pattern. The ends of the eight horizontal steel bars 10b are in contact with the vertical steel bars 10a at both ends.

  Among the 19 vertical steel bars 10a, the two vertical steel bars 10a at both ends are spaced by 97 mm, and the remaining 15 vertical steel bars 10a are spaced by 100 mm at the vertical direction (FIG. 2 (a) vertical direction). They are arranged in parallel. On the other hand, among the eight horizontal steel bars 10b, the four horizontal steel bars 10b arranged at the lower part of the fence 10 are spaced by 100 mm, and the three horizontal steel bars 10b arranged at the upper part of the fence 10 are viewed from below. In order, they are arranged in parallel in the horizontal direction (vertical direction in FIG. 2A) at intervals of 275 mm, 300 mm, and 222 mm. Therefore, the interval at which the horizontal steel bars 10 b are arranged is set narrower at the lower part of the fence 10 than at the upper part of the fence 10.

  Further, the fence 10 is a rectangular fence portion 11 and extends upward from the upper end of the fence portion 11 (upward in FIGS. 2A and 2B) and is inclined to the outside with respect to the fence portion 11. A pair of fences 10 crossed by connecting the sides of the fence part 11 to each other, and the embedded part 13 projecting like a comb tooth from the lower end of the fence part 11 Are placed side by side. A corner is formed by the pair of fences 10 arranged side by side, and the crossing angle of the corner is set in a range larger than 90 and smaller than 180 °. Therefore, in the corner, a gap is formed between the pair of creeping backs 12 (see FIG. 3).

  As shown to Fig.2 (a), the fence part 11 is a main-body part of the fence 10, Comprising: The space | interval by which the horizontal steel bar 10b is arrange | positioned is set narrower than the upper part. Therefore, a relatively small (100 mm square) grid-like gap is formed in the lower part of the fence part 11. Therefore, even a fox child (Uribo) cannot pass through the lattice-shaped gap formed at the lower part of the fence portion 11, so that it is possible to prevent the fox child from entering the fence 10 and ruining the field. On the other hand, compared to the case where the interval is set narrower in the entire range of the fence part 11, when the interval where the horizontal steel bar 10b is arranged is set narrower only in the lower part of the fence part 11, the use of the horizontal steel bar 10b is used. Since the number can be reduced, the weight of the fence 10 can be reduced and the cost can be reduced.

  As shown in FIG. 2 (b), the creeping back 12 is a portion that prevents the leap from jumping, and is formed by bending the upper end portion of the fence 10 outward at a predetermined angle θ1. In the present embodiment, the predetermined angle θ1 is set to 45 °.

  When the creeping 12 is formed on the fence 10, an illusion that the height of the fence 10 is higher than the actual height is felt, and a feeling of pressure that the fence 10 cannot jump over the fence 10 is felt. Therefore, the eagle stops the action itself trying to jump over the fence 10 and quits giving up to enter the beast protection fence 1. Therefore, it is possible to prevent the fence 10 jumping over the fence 10 from colliding with the fence 10 and damaging the fence 10, so that the durability of the fence 10 (the beast protection fence 1) can be improved.

  As shown in FIGS. 2 (a) and 2 (b), the embedded portion 13 is a portion for stably standing the fence 10, and is a lower end portion of the vertical steel rod 10a (the horizontal steel rod positioned at the lowest position). 10b to a portion protruding downward by 100 mm). Therefore, even if the ground surface where the beast protection fence 1 is installed is uneven, if the embedded portion 13 is installed so as to pierce into the ground, the lowest horizontal steel bar 10b is in contact with the ground surface ( The fence 10 can be made independent (without a gap formed between the fence portion 11 and the ground surface). Since the lattice-like gap formed at the lower part of the fence part 11 is formed in a 100 mm square, the operator's feet for installing the fence 10 can be inserted into the gap. Therefore, the operator can easily embed the embedded portion 13 in the ground by stepping on the lowermost horizontal steel bar 10b of the fence portion 11 with his / her foot.

  As described above, since the fence 10 can be made independent by the embedded portion 13, the bundling operation for connecting the fence 10 and the support column 2 (see FIG. 1) with the bundling wire K (see FIG. 1) can be easily performed. it can. Moreover, since no gap is formed between the fence portion 11 and the ground surface, it is possible to prevent small animals from entering the fence 10 through the gap. Further, since the embedded portion 13 is embedded in the ground, even if a small animal digs a hole in the ground near the lower end of the fence portion 11, the embedded portion 13 buried in the soil is only exposed and the inside and outside of the fence 10 are exposed. A hole that communicates with each other cannot be formed. Therefore, it is possible to prevent a small animal from digging the ground and entering the fence 10.

  Further, since the end portions of the eight horizontal steel rods 10b come into contact with the vertical steel rods 10a at both ends, the end portions of the horizontal steel rods 10b do not protrude from the vertical steel rods 10a constituting both sides of the fence portion 11. Therefore, when performing the connecting operation of connecting the side edges of the pair of fence parts 11 arranged side by side with the binding wire K, the end part of the horizontal steel bar 10b is connected to the vertical steel bar 10a constituting the side side of the fence part 11. Since it does not interfere, the connection operation | work which connects the side of a pair of fence part 11 can be performed easily.

  As shown in FIGS. 2C and 2D, the corner member 20 can be formed by cutting the fence 10 with an arbitrary width. In the present embodiment, the corner member 20 is formed by cutting the fence 10 with the width (200 mm) of the two horizontal steel bars 10b. Since the corner member 20 is disposed at a corner formed by a pair of fences 10 arranged side by side in a crossed state, the required lateral length varies depending on the angle of the corner. On the other hand, since the corner member 20 can be formed by cutting the fence 10 in an arbitrary width in the vertical direction, a plurality of corner members 20 having different lengths in the horizontal direction can be easily formed. Therefore, the corner crossing angle can be set arbitrarily.

  The corner member 20 is disposed inside the corner formed by the pair of fences 10 and is connected to each of the pair of fence parts 11, and the fence part 11 extends upward from the upper ends of the reinforcement parts 21. And a closing portion 22 that closes a gap formed between the pair of creeping ends 12 and a lower end portion 23 that protrudes in a comb-like shape from the lower end of the reinforcing portion 21. The The lower end portion 23 is a portion embedded in the ground like the embedded portion 13 and functions in the same manner as the embedded portion 13, so the description thereof will be omitted. The reinforcing portion 21 and the closed portion 22 will be described later with reference to FIG. 3. explain in detail.

  Further, since the corner member 20 is formed by cutting the fence 10 in the vertical direction, the reinforcing portion 21, the closing portion 22, and the lower end portion 23 are different only in the lateral length. Accordingly, the length in the vertical direction is the same as that of the fence part 11, the creeping part 12, and the embedding part 13, and the inclination angle of the blocking part 22 is the same as the inclination angle of the creeping part 12.

  Next, with reference to FIG. 3, the reinforcement part 21 and the obstruction | occlusion part 22 are each demonstrated in detail. FIG. 3A is an enlarged front view of the beast guard fence 1 at the corner, and FIG. 3B is an enlarged plan view of the beast guard fence 1 viewed from the direction IIIb in FIG.

  As shown in FIG. 3A, the reinforcing portion 21 is a member for reinforcing a corner formed by the pair of fences 10, and one side of the reinforcing portion 21 (the left side in FIG. 3A) is one side. The tie wire K is attached to the fence portion 11 (left side in FIG. 3A), the other side (right side in FIG. 3A) on the other side of the reinforcement portion 21 (right side in FIG. 3A), and the fence portion 11 on the other side. Connected. By the reinforcing portion 21 of the corner member 20, the corner angle θ2 (the angle at which the pair of fence portions 11 intersect) can be kept constant. Therefore, it prevents that one fence part 11 (fence 10) rotates with respect to the other fence part 11 (fence 10) centering on the vertical steel bar 10a which comprises the side of one fence part 11. it can. Therefore, rattling can be prevented from occurring at the corners of the pair of fence portions 11, and the joint rigidity of the corners can be improved.

  As shown in FIG. 3B, the blocking portion 22 is a portion that prevents a gap from being generated between the pair of creeping folds 12, and the blocking portion 22 is superposed on the pair of flipping folds 12. You may connect the obstruct | occluded part 22 and the wrapping 12 which were piled up by the binding wire K (refer Fig.1 (a)).

  Since the blocking portion 22 is overlapped with the pair of creepers 12, the pair of fences are arranged side by side in a state where the pair of fences intersect, and the corner crossing angle is set within a range larger than 90 and smaller than 180 °. Even when a gap is generated between the two, a part of the gap is blocked by the blocking portion 22. Therefore, since the creeping back 12 can function effectively, it is possible to make an illusion that the fence 10 cannot be jumped over. Therefore, the fence 10 can be prevented from colliding with the fence 10 and being damaged, so that the durability of the fence 10 can be improved. Further, when the blocking portion 22 and the flipping-back 12 are connected by the binding wire K, the blocking portion 22 can be prevented from floating from the pair of flipping-backs 12, and the gap generated between the pair of flipping-backs 12 can be reliably closed.

  Next, with reference to FIG. 4, the beast guard fence 100 in 2nd Embodiment of this invention is demonstrated. Fig.4 (a) has shown the state which looked at the beast protection fence 100 from the inner side (field side), ie, the partially enlarged rear view of the beast protection fence 100 in 2nd Embodiment of this invention. FIG. 4B is a partially enlarged cross-sectional view of the wildlife protection fence 100 taken along the line IVb-IVb in FIG. 4A, and FIG. 4C is the line IVc-IVc in FIG. 4B. It is a partially expanded plan view of the beast guard fence 100 in FIG. In FIG. 4C, the portion indicated by X in FIG. 4C is enlarged. The same parts as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted.

  In the wild beast protection fence 1 in the first embodiment, the electric wire holder 130 is not attached to the fence 10 and the fence can approach the immediate side of the fence 10, whereas the wild beast in the second embodiment. In the protective fence 100, the electric wire holder 130 is attached to the fence 10, and the bare electric wire D stretched outside the fence 10 is held by the electric wire holder 130. Configured to be inaccessible.

  As shown in FIGS. 4A to 4C, the electric wire holder 130 is a member for locking the bare electric wire D to the fence 10, and is made of an insulating member such as a resin. Is arranged at a height of about 120 mm from the ground, specifically from the ground. Further, the electric wire holder 130 includes a vertical locking portion 131, a horizontal locking portion 132 extending from both sides of the vertical locking portion 131, and the outside of the fence 10 from the vertical locking portion 131 (FIG. 4B). ) The arm portion 133 extends toward the left side) and the holding portion 134 formed on the arm portion 133.

  As shown in FIGS. 4 (a) and 4 (c), the vertical locking portion 131 is a portion locked to the vertical steel rod 10a and faces inward in a plan view (downward in FIG. 4 (c)). An insertion hole 131a is formed, which is formed in a U-shaped cylindrical shape that is open at the end and into which the vertical steel rod 10a is inserted. A pair of locking claws 131b are inclined and projecting outward from both ends of the vertical locking portion 131 (upward in FIG. 4 (c)) toward the insertion hole 131a, and are formed in a C shape in plan view. .

  As shown in FIGS. 4 (a) to 4 (c), the lateral locking portion 132 is a portion that is locked to the horizontal steel bar 10b, and is in the lateral direction (FIG. 4 (a) left-right direction) and below. It is formed in an L shape extending in the direction (downward direction in FIG. 4A). A semi-oval notch 132a into which the horizontal steel bar 10b is inserted and fitted is recessed in the L-shaped portion extending downward.

  As shown in FIG. 4A to FIG. 4C, the holding portion 134 is a portion that holds the bare electric wire D that is stretched outside the fence 10, from the top surface of the tip portion of the arm portion 133. A pair of upper locking pins 134a protruding and a pair of lower locking pins 134b protruding from the lower surface of the tip end portion are configured.

  Here, with reference to Fig.4 (a)-FIG.4 (c), the process of latching the bare electric wire D to the beast guard fence 100 is demonstrated. After the reinforcing portion 21 and the closing portion 22 of the corner member 20 arranged inside the corner are connected to the pair of fence portions 11 and the pair of creeping portions 12 with the binding wires K (see FIG. 1), respectively, The electric wire holder 130 is attached. Specifically, first, as shown in FIG. 4B, after the horizontal steel bar 10b is inserted and fitted into the notch 132a of the lateral locking portion 132 from above (above FIG. 4B). The vertical locking part 131 is rotated upward so that the vertical locking part 131 approaches the vertical steel bar 10a around the horizontal steel bar 10b fitted in the notch 132a. As shown in FIG. 4A, the electric wire holder 130 is attached to the fence 10 (fence portion 11) by inserting the vertical steel rod 10a into the insertion hole 131a of the vertical locking portion 131 rotated upward. . Thus, after attaching the electric wire holder 130 to each fence 10 of the beast protection fence 100, the bare electric wire D is routed so as to surround the beast protection fence 100. In this case, the bare wire D is hooked on the lower locking pin 134b and the upper locking pin 134a in an S shape in plan view, whereby the bare wire D is held by the holding portion 134, and the bare wire D is held by the wire. It is locked to the beast guard fence 100 via the tool 130.

  The pair of locking claws 131b protrudes from both ends of the vertical locking portion 131 outwardly (upward in FIG. 4C) toward the insertion hole 131a and is formed in a C shape in plan view. Therefore, the vertical steel rod 10a is guided by the inclination of the pair of locking claws 131b and is inserted into the insertion hole 131a while pushing the locking claws 131b apart. Therefore, the electric wire holder 130 can be easily attached to the fence unit 10. Further, when the vertical steel bar 10a is inserted into the insertion hole 131a, the vertical steel bar 10a is held between the tips of the pair of locking claws 131b and the inner wall of the insertion hole 131a. Therefore, it is possible to reliably prevent the vertical locking portion 131 from falling off the vertical steel rod 10a. On the other hand, the vertical locking portion 131 can be removed from the vertical steel rod 10a by spreading the pair of locking claws 131b away from each other. Therefore, the electric wire holder 130 can be easily detached from the fence 10.

  In addition, the bare electric wire D held by the electric wire holder 130 is stretched outside the fence 10, so that the beast can be repulsed by electric shock, while an arm portion is provided between the vertical locking portion 131 and the holding portion 134. Since 133 is interposed, the bare electric wire D is spaced apart from the fence 10. Therefore, the bare electric wire D can be stretched outside the fence 10 without contacting the vertical steel bar 10a and the horizontal steel bar 10b.

  Since the electric wire holder 130 is made of an insulating member, it is possible to prevent electricity from flowing from the holding portion 134 holding the bare electric wire D to the vertical steel rod 10a and the horizontal steel rod 10b via the arm portion 133. Moreover, since the horizontal locking part 132 inserted and fitted to the horizontal steel bar 10b is extended from the vertical locking part 131 inserted in the vertical steel bar 10a, the insertion hole 131a and the horizontal side of the vertical locking part 131 are extended. When the vertical steel bar 10a and the horizontal steel bar 10b are inserted into the notches 132a of the locking part 132, the rotation of the vertical locking part 131 with respect to the vertical steel bar 10a is restricted and the horizontal locking part with respect to the horizontal steel bar 10b. The rotation of 132 is restricted. Therefore, the electric wire holder 130 can be easily and stably locked to the fence 10.

  Since the electric wire holder 130 is arranged at the lower part of the fence part 11, the bare wire D is used for a small animal that wants to enter the fence 10 through a lattice-like gap at the lower part of the fence part 11 or a wild beast that wants to enter by digging the ground. Can be repulsed by electric shock.

  As described above, the present invention has been described based on each embodiment, but the present invention is not limited to each embodiment described above, and various improvements and modifications can be made without departing from the spirit of the present invention. This can be easily guessed.

  For example, in each of the above-described embodiments, the case where the moth is prevented from invading the field by the wild beast protection fence 1,100 is described. However, the present invention is not necessarily limited to this, and wild animals other than the moth invade the field. This may be prevented. In this case, it is preferable to change appropriately the space | interval by which the vertical steel bar 10a is arrange | positioned, and the space | interval by which the horizontal steel bar 10b is arrange | positioned according to the kind of the beast which prevents invasion. Thereby, the magnitude | size of the grid | lattice-like clearance gap formed with the horizontal steel bar 10b and the horizontal steel bar 10b can be changed. Therefore, when preventing the invasion of small animals smaller than the cage, the lattice-shaped gap can be formed small, so that the small animals can be surely prevented from entering the beast protection fence 1.

  Further, in each of the above embodiments, the case where the embedded portion 13 protrudes from the lower end of the fence portion 11 has been described. However, the present invention is not limited to this, and the fence 10 does not have the embedded portion 13. May be. Similarly, although the case where the lower end part 23 protrudes from the lower end of the reinforcement part 21 was demonstrated, the structure which the corner member 20 does not have the lower end part 23 may be sufficient. In this case, since the work of embedding the reinforcing portion 21 and the lower end portion 23 in the ground can be omitted, the process of installing the beast protection fence 1 can be simplified. On the other hand, even if the embedded portion 13 and the lower end portion 23 are not provided, the fence 10 is supported by the support column 2 and the corner member 20 is supported by the fence 10, so that the fence 10 and the corner member 20 are prevented from falling. .

  Further, in each of the above embodiments, the case where the arm portion 133 is extended from the vertical locking portion 131 has been described. However, the present invention is not limited to this, and the arm portion 133 is extended from the pair of lateral locking portions 132. The structure to provide may be sufficient. Moreover, the structure by which the vertical latching | locking part 131 and a pair of horizontal latching | locking part 132 are provided in series via the arm part 133 may be sufficient. In this case, since the rigidity of the electric wire holder 130 can be improved, the electric wire holder 130 can be miniaturized to the extent that the rigidity can be improved, and the cost can be reduced.
