Description

  The present invention relates to an animal intrusion prevention fence for preventing large animals such as deer and sharks and small animals such as dogs, cats and raccoons from entering an area such as an expressway.

  Conventionally, on highways, etc. that have been cut open in mountainous areas, large animals such as wild deer and sharks that lived nearby, or small animals such as dogs, cats, and raccoons invaded the road. Many accidents occur. Therefore, in order to prevent these animals from entering the expressway, it is normal to install an animal intrusion prevention fence, but the invasion of animals cannot be accurately prevented only by having a fence formally. I understand.

  In other words, large animals jump over the fence and enter the no entry area. On the other hand, the small animals enter the intrusion prohibited area through the fence gap of the fence itself or the gap between the fence lower end and the ground. Therefore, it has been proposed to cope with large animals by setting the height of the fence high or attaching a barbed wire to the upper part of the fence as disclosed in Patent Document 1. For small animals, the mesh of the panel cannot be passed as a fine rhombus mesh, and as shown in Patent Document 2, the gap between the lower end of the fence and the ground is made of a metal mesh made of a fine rhombus mesh. It has been proposed to close it with an apron.

  However, on highways, the distance required to install a fence is very long, so it is very expensive to increase the height of the fence unconditionally and to use expensive rhombus mesh panels over the entire surface. There was a problem that it was necessary. In addition, attaching barbed wire has a problem that workability is bad and there is a risk that an animal may be injured. Furthermore, when there is an error in the spacing between the columns for mounting the panel, there is a problem that the on-site dimension adjustment is difficult and the assembly work takes a long time.

  The present invention solves the problems as described above, and can surely prevent large animals such as deer and frogs and small animals such as dogs, cats and raccoons from entering an area such as a highway. Further, the present invention was completed for the purpose of providing an animal intrusion prevention fence that can reduce installation costs as much as possible and that can be easily and efficiently assembled on site.

  In order to solve the above-mentioned problems, the animal intrusion prevention fence according to the present invention has a lower panel for preventing the passage of small animals between the support columns erected at a predetermined interval, and a large animal on the upper side of the lower panel. An upper panel made of a vertical fence with a width that cannot pass through the head of the lower panel is attached, and the lower end of the lower panel is buried in the ground to eliminate the gap between the lower end of the lower panel and the ground. To do.

  Moreover, the adjustment part of the attachment position which provided the vertical fence with the space | interval narrower than the width | variety of another part shall be formed in the both-sides edge part of the said upper panel, and this shall be set to Claim 2. This is the idea.

  The said lower panel can be made into the thing of the vertical fence shape which can prevent passage of a small animal, or a fine rhombus mesh, and this is set as the invention concerning Claim 3.

  The side end portions of the two adjacent panels are fixed to the column with U-bolts, and this is the device according to claim 4.

  Furthermore, it is assumed that the upper panel and the lower panel are attached to one support column, or the support panel for attaching the upper panel is connected to the support panel for attaching the lower panel, and the upper panel is attached to the support column. It is set as the device which concerns on Claim 5 and Claim 6, respectively.

  In the device according to claim 1, since the lower panel for preventing the passage of the small animal and the upper panel made of the vertical fence having a width incapable of passing the head of the large animal are attached, the invasion of any animal, large and small, is prevented. be able to. Furthermore, since the lower end of the lower panel is buried in the ground and the gap between the lower end of the lower panel and the ground is eliminated, small animals such as dogs, cats and raccoons dig into the ground and enter. Can also be prevented.

  In the device according to claim 2, since the adjustment portion of the mounting position provided with the vertical fence is formed at both side end portions of the upper panel at intervals narrower than the width of the other portion, there is an error in the interval between the columns. Even if it exists, a dimension adjustment can be easily performed using an adjustment part.

  In the invention according to claim 3, since the lower panel has a vertical fence shape that can prevent passage of small animals or a fine rhombus mesh, it is possible to prevent invasion of animals of any size.

  Further, in the device according to claim 4, since the side end portions of the two adjacent panels are fixed to the column by the U-shaped bolts, the panels can be fixed easily and firmly.

  Further, in the device according to claim 5, the upper panel and the lower panel are attached to one support column, the equipment cost can be reduced with a simple structure, and the device according to claim 6 is further provided. As shown above, when the auxiliary column for attaching the upper panel is connected to the column for attaching the lower panel, and the upper panel is attached to the auxiliary column, the existing fence equipment can be used as it is, so it is cheaper. Can be.

It is a front view which shows embodiment of this invention. It is explanatory drawing which shows the dimension adjustment at the time of panel attachment. It is explanatory drawing which shows the dimension adjustment at the time of panel attachment. It is a perspective view of the principal part which shows the attachment state to the support | pillar of a panel. It is AA sectional drawing of FIG. It is a front view which shows other embodiment. (A) The front view which shows other embodiment, (b) The side view.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of an animal intrusion prevention fence installed on a side of an expressway. In the figure, reference numeral 1 denotes a round pipe-like column erected at a predetermined interval along the side of the road. In the illustrated example, the column 1 has a ground height of 2.5 m, and the interval between the columns 1 and 1 is 2 m. The support column 1 is inserted into a support tube 2 having a lower end portion buried in the ground, and concrete is poured into the support tube 2 and fixed. Reference numeral 20 denotes the ground.

A lower panel 3 for preventing passage of a small animal is attached between the support columns 1 and 1, and a vertical fence having a width that cannot pass through the head of a large animal is provided above the lower panel 3. An upper panel 4 is attached.
The lower panel 3 is composed of a lattice structure with a sufficiently narrow interval to prevent passage of small animals such as dogs, cats and raccoon dogs. It is comprised from the arranged horizontal fences 3b and 3b for reinforcement. This lower panel 3 is for preventing the passage of small animals, and the height of 1.5 m is sufficient.
As the lower panel 3, in addition to the one shown in FIG. 1, as shown in FIG. 6, a fine rhombus mesh may be used. However, in terms of cost, the one shown in FIG. 1 is inexpensive and advantageous.

The upper panel 4 prevents a large animal such as a deer or a frog from jumping over the lower panel 3 and entering the highway, and has a vertical fence 4a having a width that cannot pass through the head of the large animal. 4a.
As a result of research conducted by the inventor, it has been found that deer etc. have the property of pushing forward further when the head passes. After investigating that intrusion could be prevented, a panel with the above structure was developed. Therefore, the width between the vertical fences 4a and 4a is about 15 cm at the head of the deer, and is preferably less than that, preferably about 10 cm. Thus, by making the width | variety between vertical fences larger than the lower panel 3, significant cost reduction can be aimed at. In addition, the horizontal fences 4b and 4b for reinforcement can be provided suitably, and in the illustrated one, the horizontal fences 4b are provided at intervals of 30 cm. Moreover, if the ground height of the upper end of the upper panel 4 is about 2.5 m, it is possible to sufficiently prevent deer etc. from jumping and entering. In the illustrated case, the upper panel 4 is spaced 10 cm from the upper end of the lower panel 3. An upper panel 4 having a height of 90 cm is attached.
In addition, since the upper panel 4 is mainly formed by the vertical fence 4a and has few horizontal fences 4b, it can also prevent effectively that a deer etc. jumps by hooking a leg on the horizontal fence 4b.

Furthermore, the lower end portion of the lower panel 3 is buried in the ground so that no gap is generated between the lower end of the lower panel 3 and the ground 20. This prevents small animals such as dogs, cats and raccoon dogs from entering the expressway through the gaps as in the past, and the lower end is buried about 15 cm in the ground. Small animals such as cats and raccoons can also be prevented from digging holes into the ground.
The lower part of the lower panel 3 may be obtained by connecting and adding a buried panel separately formed to a standard-sized panel, or may be integrally formed as a whole.

Moreover, the adjustment part 5 of the attachment position which provided the vertical fence 4a with the space | interval narrower than the width | variety of another part is formed in the both-sides edge part of the said upper panel 4. As shown in FIG.
Each column 1 is erected in a large mountain. When a standard-sized panel is installed between these columns, if there is a dimensional error in the column spacing, the panel width will be insufficient, making installation difficult. Since there is a problem, in the present invention, the width is adjusted by the adjusting portion 5 so that the attachment can be easily performed.

Specifically, as shown in FIG. 2 to FIG. 3, the adjustment portion 5 at the attachment position in which the vertical fences 4 a are provided at both ends of the upper panel 4 at a narrower interval than the width of the other portion is formed. deep. For example, in the illustrated example, the adjustment section 5 is provided with vertical fences 4a at intervals of 5 cm, and the other sections are provided with vertical fences 4a at intervals of 10 cm. The panel is 10 cm in the part, 190 cm in the other parts, 210 cm in overall width, and 90 cm in height.
And in such a panel, as FIG. 2 shows, when there is no dimensional error in a support | pillar space | interval and a panel width, a panel is attached to a support | pillar so that the side edge part of adjacent panels may be faced | matched. On the other hand, as shown in FIG. 3, when there is a dimensional error between the column spacing and the panel width (in the illustrated case, the panel width is insufficient), the adjacent panels are separated from each other by a shortage (distance: L in the figure). The panel is attached to the column using the vertical fence 4a in the narrow interval state of the adjustment unit 5. As a result, the dimensions can be easily adjusted without preparing another connecting member or the like. In addition, what is necessary is just to attach the adjustment part 5 in the state piled up, when the panel width is surplus.

As shown in FIGS. 4 to 5, the side end portions of two adjacent panels are fixed to the column 1 by U-shaped bolts 6. Reference numeral 7 denotes a nut, and 8 denotes a fixing plate. The panel is sandwiched between the column 1 and the fixing plate 8 so that it can be easily assembled on site. Such U-bolts, nuts, and fixing plates are not limited to those shown in the drawings, and any general type can be used.
Note that the mounting configuration using the mounting position adjusting unit 5 and the U-shaped bolt 6 described above can be applied not only to the upper panel 4 but also to the lower panel 3.

6 to 7 show other embodiments.
FIG. 6 shows an example in which the upper panel 4 shown in FIG. 1 is combined with the lower panel 3 made of a general fine rhombus mesh. In the example shown in FIGS. 1 and 6, the lower panel 3 and the upper panel 4 are attached to a single column 1.

  Further, FIG. 7 shows an example in which the upper panel 4 shown in FIG. 1 is combined with a fence composed only of the lower panel 3 already installed. In this case, an auxiliary column 1a for attaching the upper panel is connected to the column 1 for attaching the lower panel, and the upper panel 4 is attached to the auxiliary column 1a. The auxiliary column 1a is attached to the column 1 with a mounting bracket 9.

  In the fence of the present invention configured as described above, a lower panel for preventing passage of small animals and an upper panel made of vertical fences for preventing jumping of large animals are attached, so small animals to large animals enter the highway. Invasion can be surely prevented, and furthermore, since the lower end of the lower panel is buried in the ground, animals that dig into the ground and enter can be prevented. In addition, the installation cost can be reduced, and the on-site assembly work can be easily and efficiently performed.
