Description

  The present invention relates to an intrusion prevention fence suitable for preventing a person or an animal from entering a protected area where a protected object such as a solar power generation facility is installed, and a method for installing the fence.

  As a result of the government's active support for the introduction of photovoltaic power generation toward the realization of a low-carbon society, the installation of photovoltaic power generation systems has been progressing rapidly in recent years. In particular, such a solar power generation system is often installed in a wilderness or the like as a large-scale solar power generation facility such as a mega solar in addition to the case where it is installed on a roof of a private house or the like. However, since wild animals inhabit such wilderness, animals may invade solar power generation facilities and cause harm to power generation equipment. On the other hand, even when such a solar power generation facility is installed in a private area, it may be harmful to the mischief of a person who has entered the facility.

  Therefore, an intrusion prevention fence for preventing intrusion of people and animals into a protected area where a protected object such as a solar power generation facility is installed has been proposed.

  For example, in Patent Document 1, a comb-like portion is formed at the lower portion of a fence body in which steel bars are arranged in a vertical direction and a horizontal direction, and this is embedded in the ground in a pierced state. According to the technology disclosed in Patent Document 1, it is possible to effectively prevent the invasion of animals due to going through the fence body by increasing the strength of the lower part of the fence body and digging the lower part of the fence body. It is what.

  However, the intrusion prevention fence disclosed in Patent Document 1 has the comb-shaped portion extending as it is from the lower portion of the fence body. In other words, the fence body and the comb-shaped portion are substantially flush with each other. It is comprised so that. Therefore, when an animal collides vigorously, the comb-like portion easily escapes from the ground according to the stress applied to the fence body, resulting in allowing the animal to enter the protected area.

  In Patent Document 2, the strength as a panel is increased by bending the upper part or the upper and lower parts of a panel formed by fixing metal meridians and parallels, thereby providing a function as a trunk edge. At the same time, a technique for providing an inexpensive fence in which the configuration of the trunk edge is omitted has been proposed.

  However, in the technique disclosed in Patent Document 2 as well, when an animal collides vigorously, the panel is deformed as long as it does not have a torso edge, which results in allowing the animal to enter the protected area. There was a problem.

  In addition to strengthening the panel itself in order to prevent animals from entering the protected area, a technical idea for strengthening a column on which the panel is built has also been proposed. Conventional intrusion prevention fences are often installed on mortar foundations. For example, in Patent Document 3, a pile whose base end side is tapered is placed in the ground. The structure which provides a support | pillar is disclosed. However, even if the strength of the struts can be strengthened in this way, if the panels installed on these columns cannot withstand the collision of animals, eventually the animals will not enter the protected area. The result is forgiving.

  Furthermore, the disclosed techniques of Patent Documents 1 to 3 do not take any measures against human intrusion other than the invasion of animals to protected areas. For this reason, the problem that the destruction activity of the protection target object by the person who invaded the protected area cannot be prevented still cannot be solved.

  Hereinafter, the form for implementing the intrusion prevention fence to which this invention is applied is demonstrated in detail, referring drawings.

  FIG. 1 is an overall perspective view of an intrusion prevention fence 1 to which the present invention is applied, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof. The intrusion prevention fence 1 includes a column 2 erected on the ground 6, a panel body 3 installed between the columns 2, and a pile 4 attached to the lower end of the column 2.

  The support 2 is erected substantially vertically on the ground 6. The support | pillar 2 is comprised with metal, The plating process may be given to the surface. For example, an H-section steel having an H-shaped cross section in which flanges are formed at both ends of the web may be used as the support column 2, or a steel pipe column having a circular cross section or a quadrangular cross section may be used. The support | pillar 2 is installed over multiple pieces at intervals mutually so that a protection land and a non-protection ground may be separated. The protected area here is an area where an object to be protected for protection from invasion of humans and animals is installed. The object to be protected is a concept including all objects for protection from invading people and animals such as railroads, roads, houses, cultivated land such as paddy fields and fields, commercial facilities, etc. in addition to photovoltaic power generation facilities. On the other hand, areas other than protected areas are non-protected areas. By providing the support column 2 so as to separate the protected area from the non-protected area as described above, the intrusion prevention fence 1 is provided along the boundary between the protected area and the non-protected area. It is possible to prevent the animal from entering the protected area through the intrusion prevention fence 1.

  The pile 4 is formed so that at least the lower end thereof is tapered. The pile 4 is inserted downward with respect to the ground 6, and is buried in the ground 6 until it reaches almost the upper end of the pile 4. A support column 2 is attached to the upper end of the pile 4. As a method of attaching the pile 4 and the support 2, for example, they may be fixed to each other by welding or the like, and when the support 2 is made of a steel pipe, its inner diameter is larger than the outer diameter of the pile 4. You may make it fix by inserting the upper end of the pile 4 in the inside of the support | pillar 2 by making it large. Conversely, the lower end of the column 2 is inserted into the opening of the pile 4 by configuring the inner diameter of the column 2 to be smaller than the outer diameter of the pile 4 and providing an opening from the upper end of the pile 4. You may make it fix with. When the pile 4 and the support column 2 are attached to each other, a bolt insertion hole (not shown) may be formed in each of the pile 4 and the support column 2 as necessary, so that they are bolted together. Furthermore, this pile 4 may be comprised with what is integrated with the support | pillar 2. By the way, when the ground 6 is composed of a concrete foundation instead of soil, the pile 4 may be embedded in the concrete foundation, or the construction of the pile 4 itself may be omitted and the lower end of the column 2 is placed in the concrete foundation. You may make it embed in.

  As shown in the front view shown in FIG. 4 and the side view shown in FIG. 5, the panel body 3 is configured by making metal wires substantially orthogonal to each other in the vertical direction and the horizontal direction. The vertical wire members 31 extending in the vertical direction are arranged on the left and right sides at substantially equal intervals. On the other hand, the horizontal wire 32 extended in the horizontal direction is arranged at intervals up and down. The horizontal wires 32 may be configured at equal intervals from each other. However, as illustrated in FIG. 4, the horizontal wires 32 are configured as a set of two groups close to each other in the vertical direction, and the intervals between the groups are configured at equal intervals. You may do it. The vertical wire 31 and the horizontal wire 32 are fixed to each other by welding.

  As shown in FIGS. 6A and 6B, the vertical wire 31 is bent downward from the lower end 41 and extended downward from the lower extension end 43 of the lower end extension 42. And a protruding insertion portion 44. The lower end extension 42 is configured to bend from the lower end 41 in a substantially horizontal direction. That is, the vertical wire 31 is extended in the vertical direction, and the lower end extension 42 is extended in a substantially horizontal direction, so that the vertical wire 31 and the lower end extension 42 are orthogonal to each other. Is formed. Similarly, since the insertion part 44 protrudes substantially vertically downward, the lower end extension part 42 and the insertion part 44 are formed so as to be orthogonal to each other. Further, a horizontal wire 32 a is attached to the lower end 41 that is the intersection of the lower end extension 42 and the vertical wire 31, and in the vicinity of the lower extension end 43 that is the intersection of the lower end extension 42 and the insertion portion 44. Is attached with a horizontal wire 32b.

  Further, as shown in FIGS. 7A and 7B, the vertical wire 31 is bent upward from the upper end 51 and extended upward from the upper extended end 53 of the upper end extension 52. And a reversing portion 54 protruding toward the surface. The upper end extension 52 is configured to bend from the upper end 51 in a substantially horizontal direction. That is, the vertical wire 31 is extended in the vertical direction, and the upper end extension 52 is extended in a substantially horizontal direction, so that the vertical wire 31 and the upper end extension 52 are orthogonal to each other. Is formed. Similarly, since the tearing portion 54 protrudes substantially vertically upward, the upper end extension portion 52 and the tearing portion 54 are formed to be orthogonal to each other. In addition, a horizontal wire 32c is attached in the vicinity of the upper end 51 that is the intersection of the upper end extension 52 and the vertical wire 31, and the upper extension end 53 that is the intersection of the upper end extension 52 and the endurance portion 54. Is attached with a horizontal wire 32d. Note that the configurations of the upper end extension portion 52 and the endurance portion 54 are not essential, and may be omitted.

  Incidentally, the upper end extension portion 52 and the endurance portion 54 and the lower end extension portion 42 and the insertion portion 44 are bent so as to be symmetrical with each other in a sectional view. As a result, the upper end extension portion 52 and the endurance portion 54, the lower end extension portion 42 and the insertion portion 44 always appear even when upside down. Therefore, it is not necessary to pay special attention to the vertical direction of the panel body 3 during construction, and the construction labor can be reduced. Moreover, since the up-down direction of the panel body 3 is made symmetrical, even when the panel body 3 is stacked over a plurality of stages, the panel body 3 is not bulky, and the transport efficiency can be improved.

  As shown in FIGS. 3 and 12, the panel body 3 having such a configuration is provided so that the lower end extension portion 42 and the insertion portion 44 are located on the protection ground side, as shown in FIGS. As a result, the lower end extension 42 is bent and extended from the lower end 41 toward the protected area. Under such a state, the panel body 3 is attached to the column 2 via the presser plate 72, the clamping plate 132, the U bolt 71, and the nut 73, as shown in FIGS. Incidentally, FIG. 8 is a plan view showing a structure for attaching the column body 3 to the support column 2, FIG. 9 is a front view thereof, and FIG. 10 is a side view thereof.

  The U bolt 71 is a bolt bent into a U-shape, and screw portions are formed at both ends thereof. The presser plate 72 is formed of a metal plate-like body, and allows U bolts 71 to be inserted into two uncut holes (not shown). A clamping plate 132 is disposed so as to face the presser plate 72. The clamping plate 132 can also be inserted with U-bolts 71 in two holes (not shown) that are similarly cut. Both ends of the sandwiching plate 132 may be bent.

  When the panel body 3 is actually attached to the column 2, the U-shaped portion of the U bolt 71 is engaged with the column 2 as shown in FIG. 8. Next, a hole (not shown) in the clamping plate 132 described above is inserted into the U bolt 71. Incidentally, the end portions of the two panel bodies 3 adjacent to each other are applied to the support column 2, and the vertical wires 31 constituting the end portions of the panel bodies 3 are respectively attached to the holding plates 132. Positioned between both ends, the end portions of the U bolts 71 are respectively inserted into holes (not shown) in the presser plate 72. Then, the nut 73 is screwed onto the screw portion at the end portion of the U bolt 71 protruding from the presser plate 72. As a result, a so-called ring body is formed between the clamping plate 132 and the presser plate 72, and the vertical wires 31 at the ends of the panel bodies 3 adjacent to each other are accommodated in the ring body. By fastening the U bolt 71 and the nut 73 firmly together, the vertical wire 31 can be firmly held by the holding plate 132 and the holding plate 72, and as a result, the end of the panel body 3 with respect to the column 2. The vertical wire 31 of the part is fixed more firmly.

  Moreover, the upper end extension part 52 in the panel body 3 will be located just above the upper end in the support | pillar 2 as shown in FIG. At this time, the upper end of the column 2 may be brought into contact with the upper end extension 52 of the panel body 3.

  FIG. 11 is a plan view showing an attachment structure to the support column 2 at the lower part of the panel body, and FIG. 12 is a side view thereof. Similarly, in the lower part of the panel body 3, as shown in FIG. 11, the U-shaped portion of the U bolt 71 is engaged with the support column 2, and the vertical wire members 31 constituting the end portions of the panel bodies 3 are respectively After being positioned between both ends of the U bolt 71 and sandwiched between the presser plate 72 and the sandwiching plate 132, these are firmly fixed via the nut 73. At this time, the lower end extension portion 42 is extended from the presser plate 72 and the nut 73 toward the protected ground side.

  Further, the lower end extension 42 may be fixed in contact with the ground 6 as shown in FIG. The extension direction of the lower end extension 42 that is bent substantially perpendicularly to the vertical wire 31 is substantially horizontal. For this reason, it fixes so that the substantially full length of the lower end extension part 42 may contact with respect to the ground 6. The insertion portion 44 protruding from the lower extension end 43 of the lower end extension portion 42 is almost entirely inserted into the ground 6 from the lower extension end 43 to the tip.

  FIG. 13 shows an example in which the lower end extension 42 is fixed in a state of being separated from the ground 6. The insertion part 44 protruding from the lower extension end 43 of the lower end extension part 42 is inserted into the ground 6.

  The panel body 3 is provided on the protected ground side with respect to the support column 2. In other words, when the vertical wire 31 is disposed with respect to the support column 2 from the protected ground side, the lower end extension 42 is designed to extend toward the protected ground side. This is because, if this lower end extension 42 is designed to extend toward the non-protected ground side, it will come into contact with the column 2.

  The effect of the intrusion prevention fence 1 to which the present invention having the above-described configuration is applied will be described. When the animal 9 collides with the intrusion prevention fence 1 to which the present invention is applied from the unprotected ground side, the vertical line 31 in the panel body 3 as shown in FIG. A bending load based on the collision force is applied. Since the lower end extension portion 42 is bent almost vertically from the lower end 41 of the vertical wire 31 corresponding to the lower end of the panel body 3, when such a bending load is applied to the panel body 3, the bending point A certain lower end 41 serves as a fulcrum, and a bending moment M of the lower end extension 42 as shown in the drawing acts. The direction of the bending moment M is the downward rotation direction in the figure with the lower end 41 as the center. When the bending moment M of the lower end extension portion 42 acts, a downward pushing force in the figure acts on the insertion portion 44 protruding from the lower extension end 43 of the lower end extension portion 42. By applying such pushing force, even if the animal 9 collides with the panel body 3, it becomes possible to resist this by the pushing force acting on the insertion portion 44, and the panel body 3 is pulled from the ground 6. It can be prevented from being pulled out.

  On the other hand, FIG. 14B shows an example in which the configuration of the lower end extension portion 42 and the insertion portion 44 is omitted, and the vertical wire is inserted into the ground 6 as it is for the panel body similar to the conventional one. In such a configuration, if the animal 9 collides with the panel body 3 in the same manner, a pulling force acts on the lower end of the vertical wire inserted into the ground 6 according to the bending load applied to the vertical wire. Will be. As a result, the vertical wire is easily pulled out from the ground 6 in response to the collision of the animal 9 with the panel body 3.

  Thus, in the present invention, the lower end extension 42 is bent in the substantially vertical direction from the vertical wire 31 to which the impact force by the animal 9 is directly applied. In other words, by providing the insertion portion 44 at a position shifted from the extending direction of the vertical wire 31, the insertion portion 44, which is an action point, can be decentered via the lower end 41 as a fulcrum. It becomes possible to convert the bending load to the bending moment. This can be made to act as a pushing force to the ground 6 via the insertion part 44 mentioned above. According to such a configuration, as the collision force by the animal 9 is loaded, a large pushing force to the ground 6 via the insertion portion 44 acts, and the resistance force by the panel body 3 against the animal 9 is further increased. As a result, it is possible to suppress the force that the panel body 3 tries to pull away from the ground 6. As a result, it becomes possible to prevent the animal 9 from pulling out the panel body 3 from the ground and entering the protected area.

  Incidentally, the example of FIG. 14A is an example in which the lower end extension 42 is fixed in contact with the ground 6. Thereby, the insertion part 44 protruding from the lower end extension part 42 can be pushed further into the back of the ground 6. As a result, it becomes possible to further increase the resistance against the collision by the animal 9. On the other hand, the example of FIG. 14C shows a case in which the animal 9 collides when the lower end extension 42 is separated from the ground 6. Also in such a case, it is possible to apply a pushing force to the ground 6 via the insertion portion 44 based on the same mechanism, and to suppress the force that the panel body 3 tries to pull away from the ground 6. However, it is certain that the pushing force by the insertion portion 44 can be increased when the lower end extension portion 42 is brought into contact with the ground 6.

  Further, the panel body 3 is not separated from the ground 6 and is inserted into the ground 6 through the insertion portion 44. Thereby, it is possible to prevent a small animal from entering the protected area through the lower part of the panel body 3.

  Further, according to the intrusion prevention fence 1 to which the present invention is applied, when the panel body 3 is provided on the protected ground side with respect to the support column 2 as described above, the U bolt is installed from the protected ground side as shown in FIGS. 71 and nut 73 are screwed and fixed. For this reason, it is difficult for a person who tries to enter from the unprotected ground side to remove the U bolt 71 and the nut 73. In addition to this, an endurance portion 54 is provided at the upper end of the panel body 3. For this reason, it is possible to prevent the person who tries to invade from the unprotected land side from climbing with this hand through the perpetual unit 54. Therefore, intrusion prevention fence 1 to which the present invention is applied can effectively prevent not only animals but also people from entering the protected area.

  Furthermore, according to the intrusion prevention fence 1 to which the present invention is applied, it is possible to ensure rigidity by providing a so-called folding structure with an upper end extension portion 52 and a turnover portion 54 at the upper end. There is no need to provide it. For this reason, it becomes possible to reduce a construction labor, and it becomes possible to shorten a construction period and to keep down a member cost and construction cost low.

  Moreover, in this invention, you may embody as an installation method of the intrusion prevention fence 1 mentioned above.

  In such a case, the struts 2 are installed at a distance from each other so as to separate the protected land and the non-protected land. Next, the panel body 3 having the above-described configuration is installed between the columns 2 while inserting at least the tip of the insertion portion 44 into the ground 6. At this time, in the process of being inserted into the ground 6, the operator may step on the lower end extension portion 42 with his / her foot. For this purpose, it is desirable that the extension width of the lower end extension 42 is set to such an extent that the operator's stepping force can be transmitted, for example, 3 cm or more. Thereby, an operator can insert the insertion part 44 in the ground 6 simply by stepping on the lower end extension part 42, and it becomes possible to aim at reduction of construction labor. In particular, when the ground of the ground 6 is hard or when the construction site is narrow and it is difficult to secure a work space, the insertion part 44 can be easily inserted by stepping on the lower end extension part 42 with a foot.

  Further, the present invention is not limited to the above-described embodiment. For example, the panel body 3 may be processed into a wave shape as shown in FIG. In the panel body 3, the horizontal wire 32 is processed into a wave shape, and the vertical wire 31 is disposed so as to be orthogonal thereto. The planar shape of the wavy horizontal wire 32 may be a regular wave shape such as a so-called sine wave or an irregular wave shape. By providing the panel body 3 processed in such a wave shape, it becomes possible to disperse the impact load caused by the collision of the animal 9.

  FIG. 16 shows an example in which the intrusion prevention fence 1 is provided on an inclined ground. A support column 2 is provided along the inclined surface, and a parallelogram-shaped panel body 3 is provided between the support columns 2 in a front view. When the support columns 2 are provided along the inclined surfaces, the arrangement heights between the adjacent support columns 2 are different from each other, but the horizontal wires 32 in the panel body 3 are inclined along the inclined surfaces, And the vertical wire 31 can be connected to these support | pillars 2 by setting it as the parallelogram shape comprised mutually parallel. By preparing such a parallelogram-shaped panel body 3 in advance, even if the boundary between the protected area and the non-protected area has a large gradient, it is possible to cope with this.

  Moreover, in the example of FIG. 17, the lower end extension part 42 ′ is not extended linearly, but is extended with a curvature and continued to the insertion part 44 ′. In such a form, the position of the lower extension end 43 in the lower end extension portion 42 ′ is not clearly shown, but is assigned to an arbitrary position between the lower end extension portion 42 ′ and the insertion portion 44 ′. . Even in such a form, it is needless to say that the same effects as described above can be obtained.

  Moreover, you may make it comprise the intrusion prevention fence 1 to which this invention is applied by providing the auxiliary member 95 as shown in FIG. 18 with respect to the existing fence. The auxiliary member 95 is the same as the panel body 3 in that the lower end extension portion 42, the lower extension end 43, and the insertion portion 44 are provided. An auxiliary vertical wire 131 is extended upward from the lower end extension 42 via the lower end 41. As for this auxiliary | assistant vertical wire 131, it is desirable for the extended width to the upper direction from the lower end 41 to be at least 3 cm or more, for example.

  The existing panel body to which the auxiliary member 95 having such a shape is attached is premised on that each configuration of the lower end extension portion 42, the lower extension end 43, and the insertion portion 44 is not provided. When the auxiliary member 95 is actually attached, the auxiliary vertical wire 131 is brought close to the vertical wire 31 in the existing panel body as shown in FIG. 18, and the vertical wire 31 and the auxiliary vertical wire are connected by the fasteners 141. 131 is sandwiched. Then, the fastener 141 is fastened and fixed via a bolt 142 and a nut (not shown).
