Description

  The present invention relates to a fence installed along a railway or a motorway laid in a mountainous area or a hilly area, etc., and a fence for an anti-fence fence that can effectively prevent people and small animals from entering a track or road. About the body.

  Conventionally, for highways and railway lines running in mountainous areas, for safety reasons, foxes, raccoons, wild boars and other animals such as foxes, raccoons, wild boars, or people can invade. An intrusion prevention fence using a wire net knitted as a net is installed as a fence for animal protection.

  However, the fence for animal protection, which is mainly composed of a wire mesh knitted in a net shape, makes a rectangular frame with a material such as steel mold, and the knitted wire mesh is stretched over this frame to form a fence body. Because it is a fence for animal protection by attaching it to a support column, in the mountain area where the installation location is an uneven surface or an inclined surface, various large and small gaps are generated between the lower edge of the fence body and the ground surface, and this gap is a beast, In particular, it has been pointed out that it is hardly useful for preventing the entry of small animals such as raccoon dogs. In addition, when the fence body is installed across a lateral groove such as a U-shaped groove, a small animal invades from the lateral groove, so that countermeasures are required.

  Even if there are no gaps or side grooves as described above, in a fence using a knitted wire mesh, a small animal gets over the fence by catching hands or claws on the mesh, or the ground is under the fence. It is known that small animals such as raccoon dogs enter the fence from there, and this is also a problem.

  Conventionally, in view of the above problems, a steel fence welded fence made separately so as not to become a clue to small animals is installed on top of the existing knitted fence body, or made separately to close the gap at the bottom of the fence Although measures such as attaching the fence body by retrofitting work have been taken, such measures not only increase the equipment cost but also have not led to a fundamental solution to the above problem.

  In view of the present situation of the conventional anti-fence fence as described above, the anti-fence fence makes it impossible to pass under the fence from the side groove even when the fence is installed across the side groove. It is an object to provide a fence body.

  The configuration of the present invention made for the purpose of solving the above problem is that the lower side of the fence body straddling the side groove in the fence for animal protection does not open to the main line side of the road or the track, but the opposite side (private side) ) Is provided with a trap body that opens and prevents small animals from entering the main line such as a road from the private side through the side groove.

  In the above configuration, the present invention provides a canopy member that closes the side groove obliquely traversed from the upper surface at the lower end portion of the installed fence when the installed fence diagonally straddles the side groove, and the front end side of the canopy member Can be formed so as to be orthogonal to the side groove, and a trap body can be provided at the front end of the canopy member. Further, the trap body may be attached to a substantially leg-shaped attachment leg provided across the side groove.

  In the present invention, when a fence is provided straddling a side groove, a trap body is provided in the side groove so as not to be opened on the main line side of the road or railway, and a small animal enters the main line side through the side groove. Therefore, it is possible to more effectively prevent small animals from entering the main line.

  Next, an embodiment of the fence installation method used in the present invention, an anti-fence fence installed by the method, and a fence body therefor will be described with reference to the drawings. FIG. 1 is a front view of an example of a fence body of an animal protection fence used in the present invention. FIG. 2 is a front view of a main part of an example in which the fence body of FIG. 1 is installed as an example of an animal protection fence used in the present invention. FIG. 4 is a left side view of the anti-animal fence used in the present invention in FIG. 2, FIG. 4 is a perspective view of an essential part of an example in which the fence installation method is applied to an existing net type fence, and FIG. FIG. 6 is a perspective view of an essential part of another example in which the fence installation method is applied to an existing net type fence, and FIG. 7 is another example of a fence used in the present invention. FIG. 8 is a plan view of an example in which the body fence used in the present invention is installed at right angles to the side grooves, and FIG. 9 is FIG. The trap body is installed in the gutter crossed by the installation fence. FIG. 10 is a right side view of FIG. 9, FIG. 11 is a plan view of an example in which an animal fence used in the present invention is installed obliquely across a side groove, and FIG. 12 is a fence used in the present invention of FIG. FIG. 13 is a plan view of another example in which the animal fence used in the present invention obliquely crosses the side groove, and FIG. 14 is a trap provided for the animal fence of FIG. It is a front sectional view of an example of a body.

  First, in FIG. 1, Fb is a fence body whose outer shape when viewed from the front is rectangular, and is configured as follows as an example. In other words, 1 is a vertical member of the fence body Fb. In the example of FIG. 1, steel rods having a thickness of 4 mmφ and a length of 1525 mm are arranged in parallel in the vertical direction at intervals of about 50 mm, and the whole is this fence body. It arrange | positions so that it may become about 1500-2000 mm so that the front width of Fb may be made. Actually, in the case of a design in which the distance between the cores of the pillars described later is 2000 mm, the width of the fence body Fb is formed to be about 2100 to 2150 mm. The front width of the fence body Fb used in the present invention can be formed to an arbitrary width depending on the number of the vertical members 1 to be used. Specifically, it is practically appropriate to have a width suitable for the type of distance between the columns installed at the installation location due to unevenness or inclination, or an appropriate width of about 500 to 3000 mm for convenience of transportation, etc. Is.

  Reference numeral 2 denotes a horizontal member which is arranged horizontally on the upper surface of the vertical member 1 which is arranged in parallel in the vertical direction in the above to be arranged with a width of about 1500 to 2000 mm. 2mm steel rods of 1500mm to 2000mm in length, which are equivalent to or slightly longer than the overall width of the vertical members 1 arranged in parallel, and arranged in parallel at an interval of about 50 to 75mm. As a set of horizontal members, on the vertical members 1 arranged as described above, four sets are arranged in this order from the upper end of the vertical member 1 at a pitch of about 400 mm, and above and below the lowermost horizontal member 2. In addition, one steel bar is disposed as each of the sub-lateral members 21 and 22 and the members 1, 2, 21, and 22 are fixed to each other at their intersections by welding, whereby the front form shown in FIG. It is formed on the frameless fence body Fb.

  Here, for each of the horizontal members 2, 21 and 22, the thickness of the steel rod to be used is selected from the steel rods having a thickness of 4 to 10 mmφ in consideration of the environment of the installation location. Usually, select from 6-8mmφ. Further, the set of two horizontal members 2 may be formed of three steel rods, and the arrangement interval of the horizontal members 2 on the vertical members 1 may be set to 400 mm or more, for example, about 500 mm. is there. In the above example, when the arrangement interval is 500 mm, three sets of two horizontal members 2 are arranged on the vertical member 1. Here, the horizontal member 2 uses a steel bar that is the same as or thicker than the vertical member 1, and uses a couple of them as a set. Even so, the strength of the entire fence body is increased, and the horizontal member 2 at the upper end of the vertical member 1 has a function to replace the trunk edge of the conventional fence.

  The fence body Fb shown in FIG. 1 is formed by a vertical member 1 having a thickness of 4 to 6 mmφ, a horizontal member 2 having a thickness of 4 to 10 mmφ, and sub horizontal members 21 and 22, and is also formed by the vertical member 1 and the horizontal member 2. Since the vertically long window (slit) 3 is about 50 mm × 400 mm in size between the cores, it is a matter of course that small animals cannot escape from the slit 3 and the span of the vertical member 1 in the slit 3 Is a steel rod of 4 to 6 mmφ and is 400 mm, so it is almost impossible or difficult to bend by hand. In other words, it is difficult to widen the width of the slit 3. It is virtually impossible to deform and slip out to the opposite side, and it is of course impossible for a person to pass through by deforming the slit 3.

  Further, in the frameless fence body Fb described above, the length of each slit 3 is 400 mm in this example. Therefore, a small animal hooks hands and claws on the lower horizontal member 2 and the sub horizontal members 21 and 22. However, a hand or a nail does not reach the horizontal member 2 positioned above them, and therefore a small animal cannot climb up the fence body Fb.

  Since the sub horizontal members 21 and 22 are provided above and below the lowermost horizontal member 2 at the lower part of the fence body Fb, the slits 31 and 32 of this portion have a smaller vertical span than the slit 3. And since each member 21 and 22 is being fixed by welding, the intensity | strength of the lower part of the fence body Fb is further strengthened.

  The fence body Fb used in the present invention formed as described above is installed as an anti-fence fence, for example, along a railway or a motorway passed through a mountainous area, but digs into the ground below the fence and enters In order to prevent the invasion of small animals coming in, the mesh sheet 4 is stuck on the ground surface on the lower front side of the fence body Fb. This point will be described with reference to FIGS.

  First, the fence body Fb in FIG. 1 is erected on the ground G with a single sheet width as the unit of the column interval (see FIGS. 2 and 3). The structure of the column 5 itself and the standing foundation 6 are substantially the same as those of the conventional fence. The fence used in the present invention has the road surface (railway or road) side of each upright column 5 as the front surface, the fence body Fb on the front surface, the lateral member 2 as the outer surface (the vertical member 1 as the front surface of the column 5). Facing each other), the both ends of each fence body Fb are overlapped and applied to the pillars 5, and the ends of the two fence bodies Fb overlapped on the front surface of each pillar 5 are here Between the two parallel steel rods, fasteners 7 such as so-called U bolts or metal belts are respectively arranged. In the case of U bolts, each bolt is tightened and each fence body Fb is fixed to each column 5. And install.

  When the fence body Fb is attached to each support column 5 as described above, the lower end 1a of the vertical member 1 of each fence body Fb slightly bites into the ground surface G, but when the lower end 1a bites into the ground surface, the front side of the fence body Fb A mesh sheet 4 is disposed (outside as viewed from the road and the track), and the front end side of the sheet 4 is pressed by the lower end 1a of the vertical member 1 of the fence body Fb, while the rear end side of the sheet 4 and At other appropriate positions, peg-shaped anchors 8 are driven to fix the sheet 4 to the ground surface G. When the mesh sheet 4 is provided in this way, the vicinity of the lower end of the fence body Fb is covered by the mesh sheet 4, so that a small animal cannot dig the ground surface of the sheet 4 portion.

  Each of the fence bodies Fb is formed by a combination of 4 to 6 mmφ vertical members and 4 to 10 mmφ horizontal members formed of steel rods, so that a number of vertically long slits 3 are formed as a mesh, so even if frameless. Since the strength of the entire fence body is large, even when this fence body Fb is installed in a snowy area, it is easy for snow to escape from each slit 3 and there is little clogging of snow. As a result, the fence for animal protection using this fence body Fb is difficult to receive the slope pressure caused by snow accumulation, the snow pressure consisting of passive snow pressure and the settling force caused by the accumulated snow, and even if it is received, each fence body Fb Are distributed and received as a whole, so that the fence for animal protection is hardly deformed by the snow pressure or the like.

  Further, in the example of the fence body Fb, one sub horizontal member 21 is arranged between the third and fourth horizontal members 2 from the top, and about 90 to 100 mm below the lowermost horizontal member 2. Since the sub horizontal members 22 are arranged at intervals and the crossed vertical and horizontal members are welded, the mesh at the lower part of the fence body Fb is reduced, and the strength of the lower part of the fence can be increased as a whole.

  The embodiment described above is an example in which a fence for fences used in the present invention is formed using a fence body Fb having a structure formed by welding vertical and horizontal members using steel bars. Since this can also be applied to a beast fence provided using a fence body according to FIG. 4, this point will be described below with reference to FIG.

  FIG. 4 is a perspective view showing an example in which the above-mentioned installation method is applied to an existing fence for animal protection. In FIG. 4, the same reference numerals as those in FIGS. 1 to 3 denote the same members and the same parts. In FIG. 4, each fence body Fb ′ made of a knitted wire net attached to a column 5 has trunk edges 23 and 24 at the upper and lower ends thereof. Since a gap g of about 5 to 10 cm is usually formed between the lower trunk edge 24 and the ground surface, it is known that small animals enter the road and the track side through this gap g.

  Therefore, here, the mesh sheet 4 is arranged on the front side (mountain side) of each fence body Fb ′ and on the ground below each fence body Fb ′. In the arrangement of the mesh sheet 4, the tip side of the mesh sheet 4 is about 10 cm as an example so that the gap g between the fence body Fb ′ and the ground surface can be closed by the tip side 41 of the sheet 4. The raised front end portion 41 was fixed to the lower end of each fence body Fb ′ or the lower trunk edge 24. Further, the horizontal portion of the mesh sheet 4 was fixed to the ground surface by a locking member such as the anchor 8 in the above example.

  The above-described mounting mode of the mesh sheet 4 not only can completely close the lower gap g in the existing fence, but also covers the ground surface of about 30-100 cm on the near side of the fence with this mesh sheet 4, so It is possible to almost completely prevent the small animals from entering the fence by digging the near side of the lower part of the fence and entering the fence from the gap g between the lower part of the fence and the ground surface.

  As an application mode when using a ready-made fence body having upper and lower trunk edges for the knitted wire mesh, as shown in FIG. 6, when attaching the fence body Fb 'to the column 5, the lower trunk edge 24 is used. (Because this fence body Fb ′ uses a net-shaped knitted wire mesh, the lower body edge 24 of the fence body Fb ′ is pulled up to the column 5 by pulling the wire net together with the body edge 24. It is possible to lower the gap g between the trunk edge 24 and the ground surface G to about 5 cm or less and attach it to the support column 5 and then lay and fix the mesh sheet 4 above. It may be. If this construction form is adopted, it is no longer necessary to raise the front end side of the mesh sheet 4 and fix it to the fence body Fb ′, and most small animals cannot pass through the reduced gap g. It becomes impossible to dig the near side.

  In the case where the above method is applied to an existing anti-fence fence, if the fence body to be used is a fence body Fb ′ made of a knitted wire net as illustrated in FIG. There is a small animal that catches the nail and climbs the fence to invade the fence (track, road side). In order to improve this point, here, when the fence body Fb ′ used for the existing fence is a fence body made of a knitted wire mesh, “ Install "Shinobi" 8.

  4 and 5 is a plastic plate or metal plate, and has a J-shape with a cross section almost inverted, and the length (left and right width) is about 2 m, which matches the distance between the columns 5 and 5. Is formed. In the case of a metal plate 8, the upper and lower end surfaces are formed in the folded portions 81 and 82 in a folded shape so that the sharp end surfaces are not injured during handling. Further, with respect to the length direction, strength is ensured by a concave groove or convex rib 83 formed along the vertical direction of the fence. Reference numeral 84 denotes a horizontal oblong hole for attachment provided at both left and right ends.

  Next, in the above-described existing or new animal fences in which the fence body is formed of a knitted wire netting, in order to prevent small animals from stepping on the mesh and climbing up as clues, FIG. 4 and FIG. As shown, the example of providing “snipping 8” has been described, but instead of this “snipping 8”, or in combination with this, the clue prevention plate 9 of the form illustrated in FIG. 7 can also be provided. This will be described below. 7, the same reference numerals as those in FIGS. 4 to 6 indicate the same members and the same parts.

  Since the fence body Fb ′ used for the existing fence in FIG. 7 is a knitted wire net, a small animal may climb the fence using the mesh as a clue, or may enter the main line (road or track) side through the gap g at the bottom. That's what I mentioned earlier. Therefore, here, the fence body Fb ′ is provided with a clasp prevention plate 9 made of metal, plastic, or a composite thereof and having a strip shape with a vertical width of about 40 to 50 cm. It was attached to each fence body Fb ′ so as to be located about 60 cm above the ground. In order to prevent climbing of a small animal that can jump up like a monkey, the upper and lower widths of the prevention plate 9 can be extended upward, or the installation position of the climbing prevention plate 9 can be increased. is there.

  In this way, even if the small animal rises in front of the fence body Fb ′, the clue prevention plate 9 having a plain surface with no holes or irregularities is provided within the reach of the hand (leg) of the small animal that has risen. Therefore, it is possible to effectively prevent the climbing of the fence by placing a hand on the mesh like the fence body Fb ′ of the conventional knitted wire mesh. In FIG. 7, 9a has a leg fixed to the wire mesh, and an attachment for attaching the prevention plate 9 to the front surface (mountain side or private side) of the fence body Fb 'through an attachment hole provided in the prevention plate 9. , 9b are fastening brackets for attaching the fixture 9a to the column 5.

  Further, in the case where there is a gap g at the lower part of the existing fence body Fb ′ in FIG. 7, vertical and horizontal members made of steel bars in the same manner as the fence body Fb used in the present invention illustrated in FIGS. Is attached to the lower part of the fence body Fb ′, and if necessary, the comb-tooth-like part on the lower side of the grid band 10 is buried in the ground. The gap g may be closed by piercing. The gap g may be filled by other wire netting, concrete placement, ground hardening improvement, or the like.

  In the above, the clue prevention plate 9 increases the strength by putting a wavy line by a curved surface in the horizontal direction, or by putting a rib on the main line side surface, or coloring the main line side surface, or other appropriate characters. It is also possible to use it as an appropriate display surface for the main line side.

  As described above, for example, the fence used in the present invention installed as an animal fence for main roads and railway tracks passing through mountainous areas is mainly provided with a side gutter for drainage provided in a form along the main line according to the terrain of the installation location. It is often provided in the form of straddling.

  In this way, when the above-mentioned anti-fence fence is provided so as to straddle the side groove, even if it is a fence with various measures described above, small animals can freely pass through the straddle side groove inside and outside the fence. It will be possible to come and go, and the significance of setting up a fence will be halved.

  Therefore, in the present invention, when the animal fence is provided across the side groove, as described with reference to FIGS. 8 to 14, by providing the trap body to be connected to the animal fence used in the present invention in the side groove. Since small animals are prevented from entering the main line from the side groove, this point will be described below with reference to FIGS. 8 to 14, the same reference numerals as those in FIGS. 1 to 7 denote the same members or the same parts.

  First, as shown in FIGS. 8 to 10, when the fence body Fb used in the present invention straddles the side groove T almost orthogonally, the side groove is formed almost directly above the side groove T in the lower part of the fence body Fb. The trap body 11 that closes the cross section of T with a small gap is provided in a suspended form on the private side (non-main line side) surface of the fence body Fb. Reference numeral 11a denotes an attachment hinge for suspending the upper end side of the trap body 11 from the fence body Fb.

  When the trap body 11 is provided in this mounting mode, as shown in FIG. 10, the trap body 11 cannot be opened to the main line side (right side of FIG. 10), but the private side (left side of FIG. 10) Since it is movable so as to be lifted by the action of the mounting hinge 11a, a small animal cannot pass through the lateral groove T from the private side to the main line side. Note that dust and fallen leaves can flow from the gap between the lower side of the trap body 11 and the bottom of the side groove T to the left or right side of FIG. For example, the accumulated fallen leaves are easily flowed downstream from the portion of the trap body 11 opened by the rainwater flow. Moreover, if the trap body 11 is lifted and opened in a vertical posture, it does not interfere with the cleaning of the side groove T.

  Although the trap body 11 is formed of a sandwich-structured plate in which both sides of a foam plate such as styrene having a thickness of about 2 mm are sandwiched between aluminum plates having a thickness of about 0.5 mm, although not shown, it can be easily damaged depending on the nails and teeth of a small animal. On the other hand, since it can be easily cut into an arbitrary size and shape with a simple tool such as a cutter knife, there is an advantage that it can be easily formed into a predetermined shape in accordance with the size of the side groove cross section at the fence installation site. In addition, the trap body 11 is much lighter than a steel rod welded net, so it is convenient to handle and is easily opened when subjected to a water flow. The plate material forming the trap body 11 can also be used as the material of the climbing prevention plate 9 described above.

  On the other hand, when the fence body Fb is provided so as to obliquely cross the side groove T, the side groove T is blocked by the embodiment illustrated in FIGS. 11 and 12 or the embodiment illustrated in FIGS. Take action.

  When the fence body Fb straddles the side groove T obliquely, the trap body 11 is directly suspended from the fence body Fb in the mounting manner described with reference to FIGS. I can't. This is because the opening operation of the trap body 11 interferes with the side wall of the side groove T and cannot be opened. Therefore, in the present invention, as illustrated in FIG. 11, in order to attach the trap body 11 in the direction orthogonal to the side groove T, the net-like canopy member 12 is attached to the private side of the fence body Fb (FIG. The trap body 11 is provided at the lower end of the canopy member 12 at the front end perpendicular to the side groove T so that the trap body 11 can be opened in only one direction with respect to the side groove T.

  In the present invention, the trap body 11 in FIG. 11 is provided so that it can be opened only in one direction in the side groove using an attachment gate body 13 having a substantially gate shape when viewed from the front as illustrated in FIG. That is, the mounting gate 13 includes a left and right leg 13a pierced into the ground across the side groove T, a beam 13b provided to connect the upper ends of both legs 13a to mount the mounting hinge 11a, and the beam The trap body 11 formed by the stopper portion 13c provided in parallel with the beam portion 13b below the portion 13b and suspended from the beam portion 13b via the mounting hinge 11a is moved to the private side by the action of the stopper portion 13c. It can be opened, but it is supported so that it cannot be opened to the main line.

  FIGS. 13 and 14 are examples in the case where the fence body Fb straddles the side groove T as in the examples shown in FIGS. 11 and 12, but in FIGS. 13 and 14, the trap body 11 to be used is In this example, a trap body 11 'formed of a mesh body is used instead of the board body of the example. In this example, a hinge 11a ′ obtained by winding a metal wire in a coil shape is used as the mounting hinge 11a ′. 13 and 14, the same reference numerals as those in FIGS. 11 and 12 indicate the same members and the same parts.

  The present invention is as described above, and in the present invention, when the animal fence is provided across the side groove, a trap body is provided in the side groove so as not to be opened on the main line side of the road or railway, Is formed so as to prevent the small animals from entering the main line through the side groove, and in combination with the climbing prevention function of the above small animals, the small animals can be more effectively prevented from entering the main line. .

  As described above, the fence body straddling the side groove of the present invention is provided with a trap body to prevent intrusion through the side groove. Therefore, it is possible to prevent intrusion from the side groove regardless of whether the fence is an existing fence or a new fence. In addition, if combined with the prevention of climbing of the fence and the animal protection by the installed fence, it can be almost perfect, and therefore, it is extremely useful as a fence body of the animal fence.
