Description

The present invention includes an animal invasion prevention laying panel laid on the ground to prevent the invasion of animals, a method for constructing the animal invasion prevention laying panel, and an animal invasion prevention method using the animal invasion prevention laying panel. Regarding.

In order to prevent animal damage such as crops being devoured by wild animals and human beings being attacked by wild animals, an animal invasion prevention body should be installed along the boundary of the area where you want to prevent the invasion of animals (animal invasion prevention area). It is being installed.

As an animal invasion preventive body, a fence-shaped one is the most common. However, in order to prevent the invasion of relatively large and ferocious animals such as wild boar with a fence-shaped animal invasion preventive body, it is necessary to construct the animal invasion preventive body robustly, and the construction work requires labor and cost. Will be. In addition, the fence-shaped animal invasion prevention body has a drawback that the aesthetic appearance after construction is spoiled. Further, if a fence-shaped animal invasion prevention body is installed, there arises a problem that not only animals but also people and vehicles cannot pass through.

In this regard, Patent Documents 1 and 2 propose a mat-shaped animal invasion prevention body (small animal invasion prevention mat) to be laid on the ground or the like. The animal invasion prevention body of the type laid on the ground or the like, such as the small animal invasion prevention mat of Patent Documents 1 and 2, has an advantage that it is easy to install, not only can the cost be suppressed, but also the aesthetic appearance can be maintained. have.

Jitsuto No. 3040697 Japanese Unexamined Patent Publication No. 10-229803

However, the animal invasion prevention bodies (small animal invasion prevention mats) of Patent Documents 1 and 2 are merely barbed wire welded in a grid pattern. Therefore, even if the animal invasion preventive bodies of Patent Documents 1 and 2 can prevent the invasion of small animals such as cats, they are relatively large animals such as wild boars and have hard hoofs. It is considered that the effect of preventing the above is not so effective.

In addition, a large number of thorns are formed on the animal invasion preventive bodies of Patent Documents 1 and 2. Therefore, when a person walks on the upper surface of the animal invasion prevention body of Patent Documents 1 and 2, the sole and the sole of the foot may be damaged. On the other hand, if a vehicle passes over the upper surface of the animal invasion prevention body of Patent Documents 1 and 2, the tire of the vehicle may be punctured. As described above, the animal invasion preventive bodies of Patent Documents 1 and 2 are not considered for the passage of people and vehicles.

The present invention has been made to solve the above problems, and although it is a type of animal invasion prevention body (laying panel for animal invasion prevention) laid on the ground or the like, it is a relatively large animal such as a wild boar. The purpose is to prevent intrusion and also allow people and vehicles to pass over the upper surface. Further, the present invention provides a method of constructing the above-mentioned animal invasion prevention laying panel on the ground or the like (a method of constructing the animal invasion prevention laying panel), or uses the above-mentioned animal invasion prevention laying panel to provide an animal. It is also an object to provide a method for preventing the invasion of animals (animal invasion prevention method).

The above issues are
An animal invasion prevention laying panel that is laid on the ground to prevent the invasion of animals.
At least the upper surface side thereof is a grid frame portion formed in a grid frame shape.
Stimulation protrusions are provided upward on the inside of each grid in the grid frame.
This is solved by providing an animal invasion prevention laying panel characterized in that the sole of an animal trying to walk on the upper side can be stimulated by a stimulating protrusion.

As described above, the animal invasion prevention laying panel of the present invention is formed in the shape of a grid frame on the upper surface side, and the stimulating protrusions are provided upward on the inside of the grid, so that the boar, etc. It is also possible to prevent the invasion of relatively large animals. That is, animals such as wild boars have a habit of extremely disliking the occurrence of discomfort on the soles of their feet, and when they feel discomfort on the soles of their feet, they have a habit of giving up moving from the place where they felt discomfort. doing. Especially for animals with hoofs, it is very difficult to walk on the hard linear part or the thin plate-like part because those parts bite into the soft part of the sole. Has the property of disliked. In this respect, the animal invasion prevention laying panel of the present invention invades the animal by stimulating the sole of the foot of the animal trying to walk on the upper surface with the upper end of the stimulating protrusion and making the animal feel uncomfortable. It is possible to give up.

Further, since the laying panel for preventing animal invasion of the present invention has a structure in which the stimulating protrusion is surrounded by a grid frame portion, it is possible for a person or a vehicle to pass above the laying panel. There is. That is, in addition to the fact that the soles of human feet and the tires of vehicles have a size larger than the grid of the grid frame portion, the above-mentioned stimulation protrusions are arranged inside each grid. There is. Therefore, even if the sole of a person or the tire of a vehicle is placed on the upper surface of the laying panel for preventing animal invasion of the present invention, the sole of the foot or the tire does not penetrate deeply into the grid.

The specific configuration of the animal invasion prevention laying panel of the present invention is not particularly limited as long as it has the above-mentioned structure. However, the laying panel for preventing animal invasion of the present invention is
An upper panel that forms a grid frame with grids that penetrate vertically,
It is composed of a lower panel in which stimulating protrusions are provided upward at positions corresponding to the respective grids of the upper panel.
When the lower panel is assembled from the lower surface side of the upper panel, it is preferable that the respective stimulation protrusions are inserted into the grid from the lower side of the grid of the upper panel.

As a result, the laying panel for preventing animal invasion of the present invention, which has a relatively complicated structure in which stimulating protrusions are arranged inside the grid in the lattice frame portion, is provided with two members (upper side) having a relatively simple structure. It can be obtained by assembling the panel and the lower panel). Therefore, it is possible not only to reduce the manufacturing cost of the animal invasion prevention laying panel, but also to maintain the strength of the animal invasion prevention laying panel.

When the laying panel for preventing animal invasion of the present invention is composed of the upper panel and the lower panel as described above, the structure of the lower panel provided with the stimulating protrusion is not particularly limited. Examples of the type of the lower panel include the following.

First, it is a lower panel of a type in which a plurality of stimulating protrusions are provided upward on the upper surface side of one plate-shaped base. This makes it possible to reduce the number of parts that make up the lower panel. Further, since the lower panel is one member in which the plate-shaped base portion and the plurality of stimulation protrusions are integrated, it is possible to easily perform the work of assembling the lower panel to the upper panel. In the following, this type of lower panel may be referred to as a "flat plate type lower panel".

Next, it is a lower panel of a type in which a plurality of stimulating protrusions are provided upward on the upper surface of each of a plurality of strip-shaped bases. The lower panel of this type corresponds to the structure in which the plate-shaped base portion of the lower panel of the flat plate type is divided into strips. By forming the lower panel into a divided structure in this way, it is possible to reduce the space for transporting and storing the lower panel. Further, it is also easy to increase the variation of the lower panel, for example, it becomes easy to switch the number of stimulating protrusions per grid by the row of grids constituting the grid frame portion. Furthermore, if a gap is provided between adjacent strip-shaped bases in the lower panel, it is possible to drain the water inside the grid through the gap, and it is possible to enhance the functionality of the lower panel. Become. In the following, this type of lower panel may be referred to as a "strip-type lower panel".

Next, it is a lower panel of a type in which a plurality of stimulating protrusions are provided upward on the upper surface side of the net-like base. The lower panel of this type corresponds to the flat plate type lower panel in which the plate-like base is replaced with the net-like base. In this way, the weight of the lower panel can be reduced by forming the portion corresponding to the plate-shaped base portion of the flat plate type lower panel into a net shape. Further, as with the flat plate type lower panel, the lower panel can be made into one member in which the net-like base portion and the plurality of stimulation protrusions are integrated. Therefore, the lower panel can be easily transported and constructed. In addition, it is possible to improve the functionality of the lower panel, such as draining the grid of the grid frame through the mesh of the mesh base. In the following, this type of lower panel may be referred to as a "net type lower panel".

The laying panel for preventing animal invasion of the present invention may be composed of an upper panel and a lower panel as described above, or may have a structure in which the entire panel is assembled in a cubic lattice frame shape.
That is, the laying panel for preventing animal invasion,
Multiple first rods arranged in one direction parallel to the upper surface,
A plurality of second bars arranged in a direction parallel to the upper surface and non-parallel to the first bar,
It is possible to form a structure in which a plurality of third rods arranged in a direction non-parallel to the upper surface thereof are assembled in a cubic lattice shape.

This makes it possible to easily assemble the animal invasion prevention laying panel of the present invention, which has a relatively complicated structure in which stimulating protrusions are arranged inside the grid in the lattice frame portion. In addition, it is possible to reduce the weight of the entire laying panel for preventing animal invasion.

As described above, according to the present invention, it is possible to prevent the invasion of relatively large animals such as wild boars while being a type of animal invasion prevention body (laying panel for preventing animal invasion) laid on the ground or the like. At the same time, it becomes possible to allow people and vehicles to pass on the upper surface. In addition, a method of constructing the above-mentioned animal invasion prevention laying panel on the ground or the like (a method of constructing the animal invasion prevention laying panel) is provided, and the above-mentioned animal invasion prevention laying panel is used to prevent animal invasion. It is also possible to provide a method (animal invasion prevention method).

A preferred embodiment of the animal invasion prevention laying panel of the present invention will be described more specifically with reference to the drawings. In the following, the laying panel for preventing animal invasion of the present invention will be described by taking as an example 10 patterns of embodiments from the first embodiment to the tenth embodiment. However, the technical scope of the animal invasion prevention laying panel of the present invention is not limited to these embodiments. The animal invasion prevention laying panel of the present invention can be appropriately modified from those of these embodiments as long as the gist of the invention is not impaired.

1. 1. Animal invasion prevention laying panel of the first embodiment First, the animal invasion prevention laying panel of the first embodiment will be described. FIG. 1 is a plan view showing a state in which the animal invasion prevention laying panel 10 of the first embodiment is viewed from above. FIG. 2 is a cross-sectional view showing a state in which the animal invasion prevention laying panel 10 of the first embodiment is constructed on the ground G and is cut in a plane perpendicular to the animal invasion prevention laying panel 10. FIG. 3 is a perspective view showing a state before and after assembling the lower panel 12 with respect to the upper panel 11 in the animal invasion prevention laying panel 10 of the first embodiment.

As shown in FIG. 2, the animal invasion prevention laying panel 10 of the first embodiment is laid on the ground G to prevent the invasion of animals. As shown in FIG. 3, the animal invasion prevention laying panel 10 has a grid frame portion 11 whose upper surface side is formed in a grid frame shape, and is used for stimulation inside each grid α in the grid frame portion 11. The protrusion β is provided.

The grid α is provided two-dimensionally (6 rows and 8 columns in the example of FIG. 3) in the vertical and horizontal directions of the animal invasion prevention laying panel 10, but in FIGS. The symbol "α" is attached only to the grid of. Similarly, the stimulating protrusion β is also provided two-dimensionally (6 rows and 8 columns in the example of FIG. 3) in the vertical and horizontal directions of the animal invasion prevention laying panel 10, but in FIGS. The symbol "β" is attached only to the stimulating protrusion β of. The fact that only some of the plurality of lattices α and the stimulating protrusions β are coded is the same in the figures after FIG.

As shown in FIG. 2, the animal invasion prevention laying panel 10 of the first embodiment can stimulate the sole of an animal trying to walk on the ground G with a stimulating protrusion β after being installed on the ground G. It has become a thing. As already mentioned, animals such as wild boars have a habit of extremely disliking the occurrence of discomfort on the soles of their feet. In this regard, the animal invasion prevention laying panel 10 of the first embodiment attempted to walk on the upper surface of the animal invasion prevention laying panel 10 in order to cross the animal invasion prevention laying panel 10 from one side to the other side. By stimulating the sole of an animal with a stimulating protrusion β to make the animal feel uncomfortable, the animal is given up invasion (crossing from one side to the other side of the animal invasion prevention laying panel 10). It has become.

Further, in the animal invasion prevention laying panel 10 of the first embodiment, as shown in FIG. 1, the periphery of the stimulating protrusion β is the lattice frame portion 11 (the first outer frame portion 11a and the second outer frame portion 11b described later). The structure is surrounded by the first partition frame portion 11c and the second partition frame portion 11d). Therefore, when the sole of an animal such as an ingot is placed on the upper surface of the laying panel 10 for preventing animal invasion, a part or the whole of the sole of the foot enters the lattice α, and the sole of the foot is the stimulating protrusion β. On the other hand, even if something larger than the sole of an animal such as an ino (the sole of a person, a tire of a vehicle, etc.) is placed on the upper surface of the laying panel 10 for preventing invasion of animals, the foot The back, tires, and the like are supported by the lattice frame portion 11 so as not to penetrate deeply into the lattice α. Therefore, the animal invasion prevention laying panel 10 of the first embodiment is capable of allowing people and vehicles to pass above it.

If the upper end of the stimulating protrusion β is formed sharply, the sole of the animal stimulated by the stimulating protrusion β may be damaged, and in addition, the sole of a person passing through the upper surface of the animal invasion prevention laying panel 10 may be damaged. There is a risk of damaging or puncturing the tires of a vehicle passing over the upper surface of the animal invasion prevention laying panel 10. Therefore, it is preferable that the upper end portion of the stimulating protrusion β is not formed sharply but is formed flat or spherical. Also in the animal invasion prevention laying panel 10 of the first embodiment, the upper end portion of the stimulating protrusion β is formed flat as shown in FIG.

The diameter D ₁ (FIG. 1) of the stimulating protrusion β is not particularly limited. However, if the stimulating protrusion β is too thin, it becomes difficult to maintain the strength of the stimulating protrusion β, such as the stimulating protrusion β being easily broken. In addition, the upper end of the stimulating protrusion β is inevitably sharpened, and the sole of a person passing through the upper surface of the animal invasion prevention laying panel 10 or the tire of the vehicle is easily damaged. Therefore, the diameter D ₁ of the stimulating protrusion β is usually set to 1 mm or more. The diameter D ₁ of the stimulating protrusion β is preferably 3 mm or more, and more preferably 5 mm or more.

On the other hand, if the stimulating protrusion β is made too thick, even if the sole of an animal such as a wild boar rests on the upper end of the stimulating protrusion β, the animal may not feel a sense of discomfort. Therefore, the diameter D ₁ of the stimulating protrusion β is usually 30 mm or less. The diameter D ₁ of the stimulating protrusion β is preferably 20 mm or less, more preferably 15 mm or less, and further preferably 10 mm or less. In the animal invasion prevention laying panel 10 of the first embodiment, the diameter D ₁ of the stimulating protrusion β is about 10 mm.

The height H ₁ (FIG. 2) of the stimulating projection β is appropriately determined according to _{the depth H 2} (FIG. 2) of the grid α and the like. At this time, if the upper end of the stimulating protrusion β protrudes upward from the upper surface of the animal invasion prevention laying panel 10 (upper opening of the grid α), a person or a vehicle may press the upper surface of the animal invasion prevention laying panel 10. It may be difficult to pass. Therefore, the height H ₁ of the stimulating projection β is usually set to be the same as the depth H ₂ of the grid α or _{lower than the depth H 2 of the grid α.} Specifically, the depth ΔH (FIG. 2) from the upper opening of the grid α to the upper end of the stimulating projection β is usually 0 mm or more. The depth ΔH is preferably 0.5 mm or more, more preferably 1 mm or more, and further preferably 2 mm or more.

However, in addition to the function of stimulating the soles of animals such as wild boars, the stimulating protrusions β prevent the soles of human feet and the tires of vehicles from locally falling into the grid β, and are laid to prevent animal invasion. It also has a function of facilitating the passage of people, vehicles, and the like on the upper surface of the panel 10. In this regard, if the depth ΔH (FIG. 2) from the upper opening of the grid α to the upper end of the stimulating protrusion β is made too large, the soles of human feet, vehicle tires, etc. may fall deep into the grid β. Therefore, there is a risk that it will be difficult for people, vehicles, etc. to pass through the upper surface of the laying panel 10 for preventing animal invasion. Therefore, this depth ΔH is usually set to 30 mm or less. The depth ΔH is preferably 20 mm or less, more preferably 15 mm or less, and further preferably 10 mm or less. In the animal invasion prevention laying panel 10 of the first embodiment, the depth ΔH is about 5 mm.

The shape (opening shape) of each grid α in the grid frame portion 11 is not particularly limited. For example, if each grid α is triangular, a triangular grid-shaped grid frame portion 11 is obtained, and if each grid α is square, a square grid-shaped grid frame portion 11 is obtained. When the grid pattern α has a regular hexagonal shape, a hexagonal grid-shaped grid frame portion 11 can be obtained. In the animal invasion prevention laying panel 1 of the first embodiment, the shape of each grid α is rectangular (more strictly, square) as shown in FIG.

If the dimensions of each grid α (front-back width W ₁ and left-right width W ₂ of the grid α in FIG. 1) are made too small, the soles of animals such as ingots will appear on the upper surface of the animal invasion prevention laying panel 10. Even if it is placed, the peripheral portion of the sole of the foot is supported by the upper end surface of the grid frame portion 11, the sole of the animal does not fall into the grid α, and the sole of the foot is a stimulating protrusion β. There is a risk that it will not be stimulated. Therefore, the front-rear width W ₁ and the left-right width W ₂ of each grid α are usually set to 5 cm or more. The front-rear width W ₁ and the left-right width W ₂ of each grid α are preferably 8 cm or more, and more preferably 10 cm or more.

However, if the dimensions of each grid α (front-back width W ₁ and left-right width W ₂ of the grid α in FIG. 1) are made too large, not only the soles of animals such as wild boars, but also the soles of humans and vehicles. Even the tires and the like of the wild boar are likely to have the grid α depressed, which may make it difficult for people or vehicles to pass through the upper surface of the laying panel 10 for preventing animal invasion. Therefore, the front-rear width W ₁ and the left-right width W ₂ of each grid α are usually set to 20 cm or less. The front-rear width W ₁ and the left-right width W ₂ of each grid α are preferably 17 cm or less, and more preferably 15 cm or less. In the animal invasion prevention laying panel 10 of the first embodiment, the front-rear width W ₁ and the left-right width W ₂ of each grid α are about 10 cm.

_{The depth H 2} of the grid α (FIG. 2) also differs depending _{on the height H 1} (FIG. 2) of the stimulating projection β, and is not particularly limited. However, if the depth H ₂ of the grid α is too shallow, the stimulating protrusions β are inevitably lowered, and the stimulating protrusions β may make it difficult to give a sense of discomfort to the soles of animals such as wild boars. Therefore, the depth H ₂ of the grid α is usually set to 2 cm or more. The depth H ₂ of the grid α is preferably 5 cm or more, and more preferably 10 cm or more.

On the other hand, if the grid α is made too deep, the animal invasion prevention laying panel 10 becomes thick and large. In addition, if the grid α is clogged with dust, soil, or the like, it may be difficult to remove it. Further, inevitably, it becomes necessary to form the stimulating protrusion β for a long time, and there is a possibility that it becomes difficult to maintain the strength of the stimulating protrusion β. Therefore, the depth H ₂ of the grid α is usually 20 cm or less. The depth H ₂ of the grid α is preferably 15 cm or less. In the animal invasion prevention laying panel 10 of the first embodiment, the depth H ₂ of the grid α is about 10 cm.

By the way, in the animal invasion prevention laying panel 10, a portion where the lattice α is formed (lattice frame portion 11) and a portion where the stimulating protrusion β is formed are integrally formed by one member. It may be. However, the animal invasion prevention laying panel 10 of the present invention has a relatively complicated structure in which the stimulating protrusions β are arranged inside the lattice α as described above, and one such structure is provided. It is not always easy to compose with members.

In this respect, the animal invasion prevention laying panel 10 of the first embodiment is configured by assembling the separately formed upper panel 11 and lower panel 12 to each other as shown in FIG. .. The upper panel 11 has a plurality of grids α penetrating vertically, and the lower panel 12 has an upward stimulating projection β at a position corresponding to each grid α of the upper panel. .. When the lower panel 12 is assembled from the lower surface side of the upper panel 11, each stimulation protrusion β in the lower panel 12 is inserted into the grid α from the lower side of the grid α of the upper panel 11. ing.

The upper panel 11 is not particularly limited in its specific form as long as it has a plurality of grids α. In the animal invasion prevention laying panel 10 of the first embodiment, as shown in FIG. 3A, the upper panel 11 is a first outer frame portion 11a and a second outer frame portion 11a, each of which is made of a strip-shaped member. It is composed of a frame portion 11b, a first partition wall portion 11c, and a second partition wall portion 11d.

The first outer frame portion 11a extends in one direction parallel to the upper surface of the upper panel 11 (left-right direction in the example of FIG. 3A), and is a member forming the outer surface of the upper panel 11. As shown in FIG. 1, the first outer frame portions 11a are provided in pairs in the front and rear on the upper panel 11. On the other hand, the second outer frame portion 11b extends in another direction parallel to the upper surface of the upper panel 11 (a direction different from the one direction; in the example of FIG. 3A, the front-rear direction), and the upper panel 11 has a second outer frame portion 11b. It is a member that forms the outer surface. As shown in FIG. 1, the second outer frame portions 11b are provided in pairs on the left and right sides of the upper panel 11.

On the other hand, the first partition wall portion 11c extends in a direction parallel to the first outer frame portion 11a (left-right direction in the example of FIG. 3A), and the first outer frame portion 11a and the second outer frame portion 11b. It is a member that partitions the inner space of. As shown in FIG. 1, a plurality of the first partition wall portions 11c are provided, and are arranged substantially in parallel with each other in a predetermined direction in the front-rear direction. On the other hand, the second partition wall portion 11d extends in a direction parallel to the second outer frame portion 11b (in the front-rear direction in the example of FIG. 3A), and is inside the first outer frame portion 11a and the second outer frame portion 11b. It is a member that divides the space. As shown in FIG. 1, a plurality of the second partition wall portions 11d are also provided, and are arranged substantially in parallel with each other at predetermined intervals in the left-right direction.

In the animal invasion prevention laying panel 10 of the first embodiment, the space partitioned by the first outer frame portion 11a, the second outer frame portion 11b, the first partition wall portion 11c, and the second partition wall portion 11d, the first The space is partitioned by the outer frame portion 11a, the first partition wall portion 11c, and the second partition wall portion 11d, and is partitioned by the second outer frame portion 11b, the first partition wall portion 11c, and the second partition wall portion 11d. Each of the space and the space partitioned by the first partition wall portion 11c and the second partition wall portion 11d form a grid pattern α.

The materials of the first outer frame portion 11a, the second outer frame portion 11b, the first partition wall portion 11c, and the second partition wall portion 11d are not particularly limited as long as they have the required strength. Examples of the material of the first outer frame portion 11a and the like include metal, concrete, wood and the like. However, in concrete, the upper panel 11 becomes heavier, which may make it difficult to transport and construct the laying panel 10 for preventing animal invasion. In addition, wood is easily corroded, and there is a risk that the strength cannot be maintained over time. Therefore, the material of the first outer frame portion 11a, the second outer frame portion 11b, the first partition wall portion 11c, and the second partition wall portion 11d is usually made of metal.

Also in the animal invasion prevention laying panel 10 of the first embodiment, the first outer frame portion 11a, the second outer frame portion 11b, the first partition wall portion 11c, and the second partition wall made of a strip-shaped metal plate are all formed. The upper panel 11 is formed by integrating the portion 11d with the portion 11d. The method of integrating the first outer frame portion 11a, the second outer frame portion 11b, the first partition wall portion 11c, and the second partition wall portion 11d is not particularly limited, and the metal plates forming them are welded to each other. Examples thereof include a method, a method of screwing each other, and a method of fitting each other.

The lower panel 12 is usually composed of a plurality of stimulating protrusions β and a base portion 12a supporting these stimulating protrusions β, as shown in FIG. 3A. The base 12a can adopt various forms as described later. In the animal invasion prevention laying panel 10 of the first embodiment, as shown in FIG. 3A, a plurality of stimulating protrusions β are directed upward on the upper surface side of _{one plate-shaped base portion 12a 1 having a rectangular shape.} The provided one is used as the lower panel 12. The lower panel 12 in the animal invasion prevention laying panel 10 of the first embodiment corresponds to the above-mentioned "flat plate type lower panel".

In the animal invasion prevention laying panel 10 of the first embodiment, the lower panel 12 is formed by welding the stimulating protrusion β made of a metal rod to the _{plate-shaped base portion 12a 1 made of a metal plate.} Not limited to this. For example, a screw hole that penetrates a metal plate (plate-shaped base 12a ₁ ) up and down is provided, and a bolt is screwed upward from the lower side of the screw hole, and the screw shaft portion of the bolt that protrudes upward from the screw hole. A structure or the like in which is used as a stimulating protrusion β is also possible.

By configuring the animal invasion prevention laying panel 10 as described above, the animal invasion prevention laying panel 10 having a relatively complicated structure is combined with the upper panel 11 and the lower panel 12 having a relatively simple structure. It becomes possible to obtain by assembling. Therefore, it is possible not only to reduce the manufacturing cost of the animal invasion prevention laying panel 10, but also to maintain the strength of the animal invasion prevention laying panel 10.

The animal invasion prevention laying panel 10 of the first embodiment may be laid directly on the ground G. However, since the animal invasion prevention laying panel 10 has a certain thickness, if it is laid on the ground G as it is, a step corresponding to the thickness is generated. Therefore, as shown in FIG. 2, it is preferable that the animal invasion prevention laying panel 10 has a hole dug in the ground G and is embedded in the hole. This makes it possible to align the height of the upper surface of the animal invasion prevention laying panel 10 with the height of the ground G, and prevent the above-mentioned step from occurring.

At this time, if the animal invasion prevention laying panel 10 is embedded as it is in the hole dug in the ground G, the animal invasion prevention laying panel 10 may rattle or sink. Therefore, as shown in FIG. 2, it is preferable to drive the foundation concrete 30 into the bottom of the hole dug in the ground G to cure it, lay the rubber sheet 30 on the upper side thereof, and then lay the laying panel 10 for preventing animal invasion. .. This makes it possible to prevent rattling and sinking of the laying panel 10 for preventing animal invasion.

The type of animal to be prevented from invading by the animal invasion prevention laying panel 10 of the first embodiment is not particularly limited. Examples of the animal that can be prevented from invading by the animal invasion prevention laying panel 10 of the first embodiment include a deer, a weasel, a raccoon dog, a dog, a cat, and the like, in addition to a wild boar. All of these animals have a habit of disliking the feeling of discomfort on the soles of their feet.

2. Animal invasion prevention laying panel of the second embodiment Next, the animal invasion prevention laying panel 10 of the second embodiment will be described. Regarding the animal invasion prevention laying panel 10 of the second embodiment, only the configuration different from the animal invasion prevention laying panel 10 of the first embodiment will be described, and it is common to the animal invasion prevention laying panel 10 of the first embodiment. The explanation of the configuration is omitted. As for the configuration not mentioned in the animal invasion prevention laying panel 10 of the second embodiment, the same configuration as described in the animal invasion prevention laying panel 10 of the first embodiment can be adopted.

FIG. 4 is a plan view showing a state in which the animal invasion prevention laying panel 10 of the second embodiment is viewed from above. In the animal invasion prevention laying panel 10 of the first embodiment, as shown in FIG. 1, one stimulating protrusion β was arranged for each lattice α. On the other hand, in the animal invasion prevention laying panel 10 of the second embodiment, as shown in FIG. 4, a plurality of stimulation protrusions β are arranged for each lattice α.

By arranging a plurality of stimulating protrusions β on one grid α in this way, it is difficult for the soles of human feet and vehicle tires to enter the grid α, and the upper surface of the laying panel 10 for preventing animal invasion is prevented. It will be possible for people and vehicles to pass more easily. In addition, the load of a person or vehicle passing over the upper surface of the animal invasion prevention laying panel 10 is easily dispersed in a plurality of stimulation protrusions β, and it is difficult for a local load to be applied only to one stimulation protrusion β. Therefore, it is possible to make the stimulating protrusion β less likely to be damaged.

The number of stimulating protrusions β in one grid α may be the same for all grids α, or may be changed depending on the grid α. For example, the number of stimulating protrusions β in the lattice α of the portion where the load is easily applied may be increased from the number of the stimulating protrusions β in the lattice α of the portion where the load is difficult to be applied.

When a plurality of stimulation protrusions β are arranged in one lattice α, the number of stimulation protrusions β in one lattice α is not particularly limited. The number of stimulating protrusions β in one lattice α can be two, three, four, or five or more. However, if the number of stimulating protrusions β in one lattice α becomes too large, the gap between the adjacent stimulating protrusions β and the gap between the stimulating protrusions β and the lattice frame portion 11 become narrow, and animals such as wild boars. However, there is a risk that it will be difficult to feel a sense of discomfort on the soles of the feet. In addition, there is a possibility that dust, soil, etc. are likely to be clogged in these gaps.

Therefore, the number of stimulating protrusions β in one lattice α is usually 20 or less. The number of stimulating protrusions β in one lattice α is preferably 10 or less, and more preferably 8 or less. In the animal invasion prevention laying panel 10 of the second embodiment, the number of stimulating protrusions β in one lattice α is 5, and the other four stimulating protrusions β are centered on the stimulating protrusion β in the middle. The protrusions β are arranged symmetrically (rotational symmetry). By arranging a plurality of stimulation protrusions β symmetrically in this way, the above effect can be more easily exerted.

3. 3. Animal invasion prevention laying panel of the third embodiment Next, the animal invasion prevention laying panel 10 of the third embodiment will be described. Regarding the animal invasion prevention laying panel 10 of the third embodiment, only the configuration different from the animal invasion prevention laying panel 10 of the first embodiment will be described, and it is common to the animal invasion prevention laying panel 10 of the first embodiment.

By forming the lower panel 12 into a plurality of strip-shaped bases 12a ₂ in this way, it is possible to reduce the space for transporting and storing the lower panel 12. Further, it is also easy to increase the variation of the lower panel 12, for example, it becomes easy to switch the number of stimulating projections β per one lattice α by the row of the lattice α. Further, if a gap is provided between the adjacent strip-shaped bases 12a ₂ , it is possible to drain the inside of the grid α through the gap, and it is possible to enhance the functionality of the lower panel. .. The lower panel 12 in the animal invasion prevention laying panel 10 of the third embodiment corresponds to the above-mentioned "strip plate type lower panel".

By forming the base portion 12a into a net-like shape (reticulated base portion 12a ₃ ) in this way, it is possible to reduce the weight of the lower panel 12. Further, the lower panel 12 can be easily transported and constructed as one member in which the net-like base portion 12a _{3 and the plurality of stimulating protrusions β are integrated.} In addition, the lower panel 12 can be made highly functional, for example, the grid β can be drained through the mesh of the mesh _{base 12a 3.} The lower panel 12 in the animal invasion prevention laying panel 10 of the fourth embodiment corresponds to the above-mentioned "net type lower panel".

5. Animal invasion prevention laying panel of the fifth embodiment Next, the animal invasion prevention laying panel 10 of the fifth embodiment will be described. Regarding the animal invasion prevention laying panel 10 of the fifth embodiment, only the configuration different from the animal invasion prevention laying panel 10 of the first embodiment will be described, and it is common to the animal invasion prevention laying panel 10 of the first embodiment. The explanation of the configuration is omitted. For the configurations not mentioned in the animal invasion prevention laying panel 10 of the fifth embodiment, the same configurations as those described in the animal invasion prevention laying panel 10 of the first embodiment and the second embodiment shall be adopted. Can be done.

FIG. 7 is a perspective view showing the animal invasion prevention laying panel 10 of the fifth embodiment. In FIG. 7, for convenience of illustration, the stimulating protrusion β is indicated by an upward arrow. FIG. 8 is an enlarged perspective view showing the connecting portions of the first bar member 10a, the second bar member 10b, and the third bar member 10c in the animal invasion prevention laying panel 10 of the fifth embodiment. In FIG. 8, for convenience of illustration, the stimulating protrusion β is shaded and hatched.

As shown in FIG. 3, the animal invasion prevention laying panel 10 of the first embodiment was formed of a plate-shaped member or a strip-shaped member substantially entirely except for the stimulating protrusion β. On the other hand, in the animal invasion prevention laying panel 10 of the fifth embodiment, as shown in FIG. 7, a plurality of rods 10a, 10b, and 10c are assembled in a cubic lattice shape. Specifically, as shown in FIG. 8, an animal is formed by assembling a plurality of first rods 10a, a plurality of second rods 10b, and a plurality of third rods 10c in a cubic lattice pattern. It constitutes an intrusion prevention laying panel 10. The first bar 10a is arranged in one direction parallel to the upper surface of the animal invasion prevention laying panel 10 (in the example of FIG. 8, the front-rear direction). The second bar 10b is arranged in a direction parallel to the upper surface of the animal invasion prevention laying panel 10 and non-parallel to the first bar 10a (left-right direction in the example of FIG. 8). The third bar 10c is arranged in a direction non-parallel (vertical in the example of FIG. 8) to the upper surface of the animal invasion prevention laying panel 10.

In these rods 10a, 10b, 10c, the ring-shaped portion formed at the end thereof is connected to the other rods 10a, 10b, 10c, or the end is connected to the other rods 10a, 10b, 10c. It can be assembled into a state of being integrated with each other by welding or the like. In addition, in the animal invasion prevention laying panel 10 of the fifth embodiment, the stimulating protrusion β is formed of a bar having a ring-shaped lower end portion thereof, and the ring-shaped stimulating protrusion β is formed. Is connected to the second bar 10b (may be connected to the first bar 10a), and the middle part of the stimulating protrusion β is provided in the middle part of the second bar 10b in a ring shape. By inserting it through a portion (a ring-shaped portion provided in the middle portion of the first bar 10a), the portion is arranged upward inside the lattice α.

By forming the animal invasion prevention laying panel 10 into a cubic lattice shape in this way, the animal invasion prevention laying panel 10 having a relatively complicated structure can be easily assembled. Further, it is possible to reduce the weight of the entire laying panel 10 for preventing animal invasion.

Further, as shown in FIG. 7, the animal invasion prevention laying panel 10 of the fifth embodiment is provided with an animal invasion prevention fence 20 which did not exist in the animal invasion prevention laying panel 10 of the first embodiment. There is. The animal invasion prevention fence 20 is a part that functions as a barrier when an animal such as a wild boar tries to jump over the animal invasion prevention laying panel 10.

The animal invasion prevention fence 20 may have a structure separated from the animal invasion prevention laying panel 10. However, in the animal invasion prevention laying panel 10 of the fifth embodiment, the animal invasion prevention fence 20 is rotatable around the edge of the animal invasion prevention laying panel 10 via a hinge or the like (FIG. 7). It is connected in a state of being rotatable in the direction of the arrow A in. Therefore, the animal invasion prevention fence 20 may be in a state of lying down with respect to the animal invasion prevention laying panel 10 when it is not needed, and in a state of standing upright with respect to the animal invasion prevention laying panel 10 only when necessary. You can do it.

The animal invasion prevention fence 20 may be formed of a plate-shaped member having a continuous surface shape, but in this case, the presence of the animal invasion prevention fence 20 may become too large and spoil the landscape. is there. There is also a problem that the weight of the animal invasion prevention fence 20 becomes large. Therefore, in the animal invasion prevention laying panel 10 of the fifth embodiment, the animal invasion prevention fence 20 is formed in a mesh shape to maintain the landscape and reduce the weight.

In addition, in the animal invasion prevention laying panel 10 of the fifth embodiment, the shape and dimensions of the mesh in the animal invasion prevention fence 20 match the shape and dimensions of the grid α on the upper surface of the animal invasion prevention laying panel 10. I'm letting you. Therefore, even when the animal invasion prevention fence 20 is laid down with respect to the animal invasion prevention laying panel 10, the mesh of the animal invasion prevention fence 20 overlaps with the grid α of the animal invasion prevention laying panel 10. Therefore, the upper side of the grid α is not blocked. Therefore, even if the animal invasion prevention fence 20 is in the collapsed state, the animal invasion prevention laying panel 10 can exert its function (the function of stimulating the sole of an animal such as a wild boar with a stimulating protrusion β). It has become.

6. Animal invasion prevention laying panel of the sixth embodiment Next, the animal invasion prevention laying panel 10 of the sixth embodiment will be described.

In the animal invasion prevention laying panel 10 of the first embodiment, as shown in FIG. 1, the front-rear width W ₁ and the left-right width W _{2 of} each grid α are substantially equal, and the grid α is viewed in a plan view. The shape was almost square. On the other hand, in the animal invasion prevention laying panel 10 of the sixth embodiment, as shown in FIG. 9A, the front-rear width W ₁ (see FIG. 1) of _{each grid α is the left-right width W 2} (see FIG. 1). It is longer than (see FIG. 1), and the plan view shape of the grid α is substantially rectangular. In the animal invasion prevention laying panel 10 of the sixth embodiment, the front-rear width W ₁ of each grid α is set to about 100 mm, and the left-right width W ₂ of each grid α is set to about 30 to 40 mm. In this way, the grid pattern α can have its front-rear width W ₁ and its left-right width W ₂ different from each other.

_{When the front-rear width W 1} and the left-right width W ₂ of the grid α are different from each other as in the animal invasion prevention laying panel 10 of the sixth embodiment, the animal invasion prevention laying panel 10 has the grid α. The long side direction (front-back direction) of is the invasion direction of animals and the traveling direction of people and vehicles (the long side direction (front-back direction) of the grid α is the course direction of roads, etc.). Is preferable. Further, as shown in FIG. 9A, it is preferable to arrange a plurality of (three in the example of the same figure) stimulating projections β inside each lattice α. As a result, the laying panel 10 for preventing animal invasion can be made easier for people and vehicles to pass through, while making it more difficult for animals (particularly animals having hoofs) to walk.

Further, in the animal invasion prevention laying panel 10 of the first embodiment, as shown in FIG. 1, the upper end surfaces of the first outer frame portion 11a and the second outer frame portion 11b of the upper panel 11 are formed flat. .. On the other hand, in the animal invasion prevention laying panel 10 of the sixth embodiment, as shown in FIGS. 9 (b) and 9 (d), the upper end surfaces of the first outer frame portion 11a and the second outer frame portion 11b. The uneven γ is provided on the upper end surface of the first partition wall portion 11c and the second partition wall portion 11d. These unevenness γ function as a non-slip (particularly, a tire non-slip when a vehicle passes) on the upper surface of the animal invasion prevention laying panel 10 when a person or a vehicle passes through. As a result, the laying panel 10 for preventing animal invasion can be made easier for people and vehicles to pass through.

7. Animal invasion prevention laying panel of the seventh embodiment Next, the animal invasion prevention laying panel 10 of the seventh embodiment will be described. Regarding the animal invasion prevention laying panel 10 of the seventh embodiment, only the configuration different from the animal invasion prevention laying panel 10 of the first embodiment will be described, and it is common to the animal invasion prevention laying panel 10 of the first embodiment. The explanation of the configuration is omitted. For the configurations not mentioned in the animal invasion prevention laying panel 10 of the seventh embodiment, the same configurations as those described in the animal invasion prevention laying panel 10 of the first embodiment and the second embodiment shall be adopted. Can be done.

FIG. 10 is a perspective view showing how the lower panel 12 is assembled to the upper panel 11 in the animal invasion prevention laying panel 10 of the seventh embodiment. FIG. 10A shows a state before the lower panel 12 is assembled to the upper panel 11, and FIG. 10B shows a state after the lower panel 12 is assembled to the upper panel 11. ing. FIG. 11 is a perspective view showing a lower panel 12 constituting the animal invasion prevention laying panel 10 of the seventh embodiment. FIG. 11 (a) shows a state before the stimulating protrusion β is cut out from the _{plate-shaped base portion 12a 1} forming the lower panel 12, and FIG. 11 (b) shows the stimulating protrusion β from the _{plate-shaped base portion 12a 1.} The state after cutting up is shown respectively. FIG. 12 is a perspective view showing a lower panel 12 constituting the animal invasion prevention laying panel 10 of the seventh embodiment, and is an enlarged view of a portion B in FIG. FIG. 12 (a) shows a state before the stimulating protrusion β is cut out from the _{plate-shaped base portion 12a 1} forming the lower panel 12, and FIG. 12 (b) shows the stimulating protrusion β from the _{plate-shaped base portion 12a 1.} The state after cutting up is shown respectively.

In each of the animal invasion prevention laying panels 10 described in the first to sixth embodiments described above, the lower panel 12 was composed of a plurality of members. In particular, the stimulating protrusion β is formed by fixing a member different from the portion other than the stimulating protrusion β (plate-shaped base portion 12a _{1, etc.) on the lower panel 12 to the plate-shaped base portion 12a 1,} etc. after the fact. It was provided. Therefore, in the animal invasion prevention laying panel 10 from the first embodiment to the sixth embodiment, it takes time and effort to manufacture the lower panel 12, and as a result, the manufacturing cost of the animal invasion prevention laying panel 10 is high. There was a risk that it would be difficult to suppress.

On the other hand, in the animal invasion prevention laying panel 10 of the seventh embodiment, as shown in FIG. 11, the lower panel 12 is composed of _{one member (plate-shaped base portion 12a 1).} In other words, the stimulating protrusion β is formed by cutting up from the _{plate-shaped base portion 12a 1.} Moiety Specifically, as shown in FIG. 12 (a), after cutting along the plate-shaped base portion 12a ₁ to the cutting line L _1, as shown in FIG. 12 (b), forming the stimulus projections β and by causing outright folded at folding lines L _2, is provided with stimulus projections beta.

This makes it possible to manufacture the lower panel 12 in two steps of cutting the plate-shaped base portion 12a _{1 and cutting up the stimulating protrusion β.} Therefore, it is possible to reduce the labor required for manufacturing the lower panel 12 and reduce the manufacturing cost of the animal invasion prevention laying panel 10. As shown in FIG. 11, the lower panel 12 has a plurality of stimulating protrusions β, and these plurality of stimulating protrusions β are simultaneously punched using a punch having a large number of blades formed, and a large number of the stimulating protrusions β are punched at the same time. By moving the member on which the cut-up protrusion is formed _{upward from the lower surface side of the plate-shaped base portion 12a 1} , the cut-up protrusion can be cut up at the same time.

In the animal invasion prevention laying 10 of the seventh embodiment _{, an opening 12a 5} is formed in _{the plate-shaped base portion 12a 1} after the stimulating protrusion β is cut up, as shown in FIG. 12 (b). The opening 12a ₅ makes it possible to reduce the weight of the lower panel 12. In addition, rainwater or the like collected in the grid α (FIG. 10) of the animal invasion prevention laying panel 10 can be discharged through the _{openings 12a 5.}

Incidentally, in the animal antiintrusion laying 10 of the seventh embodiment, as shown in FIG. 12 (a), has a through hole 12a ₄ provided at both ends of the folding line L _2. The through hole 12a ₄ reduces the resistance when the stimulating protrusion β is cut up from the plate-shaped base portion 12a _{1, and makes it possible to easily form the stimulating protrusion β.} In addition, the lower panel 12 can be further reduced in weight. The through hole 12a ₄ also, similarly to the cutting line L ₁ described above, it is possible to punch simultaneously using a punch a large number of blades is formed.

In the animal invasion prevention laying 10 of the seventh embodiment, the stimulating protrusion β has a triangular shape in a lateral view as shown in FIG. 12 (b). However, the morphology of the stimulating process β formed by cutting up is not limited to this. Hereinafter, variations in the morphology of the stimulating protrusion β formed by cutting up will be described with some examples.

8. The animal invasion prevention laying panel 10 of the eighth embodiment will be described. Regarding the animal invasion prevention laying panel 10 of the eighth embodiment, only the configuration different from the animal invasion prevention laying panel 10 of the seventh embodiment will be described, and it is common to the animal invasion prevention laying panel 10 of the seventh embodiment. The explanation of the configuration is omitted. As for the configuration not mentioned in the animal invasion prevention laying panel 10 of the eighth embodiment, the same configuration as described in the animal invasion prevention laying panel 10 of the seventh embodiment can be adopted.

FIG. 13 is a perspective view showing a lower panel constituting the animal invasion prevention laying panel 10 of the eighth embodiment, and is an enlarged view of a portion corresponding to a portion B in FIG. FIG. 13 (a) shows a state before the stimulating protrusion β is cut out from the _{plate-shaped base portion 12a 1} forming the lower panel 12, and FIG. 13 (b) shows the stimulating protrusion β from the _{plate-shaped base portion 12a 1.} The state after cutting up is shown respectively.

In the animal invasion prevention laying panel 10 of the seventh embodiment described above, as shown in FIG. 12B, the tip of the stimulating protrusion β was sharply pointed. For this reason, the soles of the animals tend to feel uncomfortable, and the invasion of the animals can be prevented more effectively. However, there is a risk that the animals may be injured and a child who has fallen on the laying panel 10 for preventing the invasion of the animals. There was a risk of injury when the hand entered the grid α (FIG. 10).

In this regard, in the animal invasion prevention laying panel 10 of the eighth embodiment, as shown in FIG. 13 (b), the stimulating protrusion β has a substantially triangular shape in the lateral view, but the tip thereof. The part has a rounded shape. Therefore, even if the sole of an animal or a human hand touches the tip of the stimulating protrusion β, it is difficult to injure. That is, it is possible to make the laying panel 10 for preventing the invasion of animals highly safe while preventing the invasion of animals without damaging animals and humans.

9. Animal invasion prevention laying panel of the ninth embodiment Next, the animal invasion prevention laying panel 10 of the eighth embodiment will be described. Regarding the animal invasion prevention laying panel 10 of the ninth embodiment, only the configuration different from the animal invasion prevention laying panel 10 of the seventh embodiment and the eighth embodiment will be described, and the seventh embodiment and the eighth embodiment will be described. The description of the configuration common to the animal invasion prevention laying panel 10 is omitted. For the configurations not mentioned in the animal invasion prevention laying panel 10 of the ninth embodiment, the same configurations as those described in the animal invasion prevention laying panel 10 of the seventh embodiment and the eighth embodiment shall be adopted. Can be done.

FIG. 14 is a perspective view showing the lower panel 12 constituting the animal invasion prevention laying panel 10 of the ninth embodiment, and is an enlarged view of a portion corresponding to the portion B in FIG. .. FIG. 14 (a) shows a state before the stimulating protrusion β is cut out from the _{plate-shaped base portion 12a 1} forming the lower panel 12, and FIG. 14 (b) shows the stimulating protrusion β from the _{plate-shaped base portion 12a 1.} The state after cutting up is shown respectively.

In the animal invasion prevention laying panel 10 of the seventh embodiment and the eighth embodiment described above, as shown in FIGS. 12 (b) and 13 (b), the stimulating protrusion β has a triangular shape in a lateral view. It was. On the other hand, in the animal invasion prevention laying panel 10 of the ninth embodiment, as shown in FIG. 14B, the side view shape of the stimulating protrusion β is a quadrangular shape. More specifically, it has a trapezoidal shape. By forming the tip of the stimulating protrusion β into a flat shape in this way, the safety of the animal invasion prevention laying panel 10 can be enhanced without forming the tip of the stimulating protrusion β to be round. ..

As described above, the morphology of the stimulating protrusion β of the cut-up type is not uniform, and there are various variations.

10. Animal invasion prevention laying panel of the tenth embodiment Finally, the animal invasion prevention laying panel 10 of the tenth embodiment will be described. Regarding the animal invasion prevention laying panel 10 of the tenth embodiment, only the configuration different from the animal invasion prevention laying panel 10 of the first to ninth embodiments will be described, and the first to ninth embodiments will be described. The description of the configuration common to the animal invasion prevention laying panel 10 up to this point is omitted. With respect to the configuration not mentioned in the animal invasion prevention laying panel 10 of the tenth embodiment, the same configuration as described in the animal invasion prevention laying panel 10 of the first to tenth embodiments is adopted. be able to.

FIG. 15 is a perspective view showing the animal invasion prevention laying panel 10 of the tenth embodiment, and is an enlarged view of the periphery of the grid α. FIG. 16 is a perspective view showing another example of the animal invasion prevention laying panel 10 of the tenth embodiment, and is an enlarged view of the periphery of the grid α. 15 (a) and 16 (a) show the state before the reinforcing pipe 13 is fitted into the grid α, and FIGS. 15 (b) and 16 (b) show the state before the reinforcing pipe 13 is fitted into the grid α. It shows the state after it is crowded.

In each of the animal invasion prevention laying panels 10 from the first embodiment to the ninth embodiment described above, the upper panel 11 was formed of metal. Therefore, as in the animal invasion prevention laying panel 10 (FIG. 3) of the first embodiment, the upper panel 11 is the first outer frame portion 11a, the second outer frame portion 11b, the first partition frame portion 11c, and the first. In the case of being composed of two partition frame portions 11d, these frame portions 11a, 11b, 11c, 11d are formed by punching from a metal plate, and these frame portions 11a, 11b, 11c, 11d are combined and welded or the like. Had to be joined by. Therefore, there is a risk that the manufacturing cost of the upper panel 11 will increase. In particular, when the uneven γ is provided on the upper end surfaces of the frame portions 11a, 11b, 11c, 11d as in the animal invasion prevention laying panel 10 (FIG. 9) of the sixth embodiment, the manufacturing cost of the upper panel 11 is high. It was easy to become.

In this respect, in the animal invasion prevention laying panel 10 of the tenth embodiment, the upper panel 11 is made of hard resin. Therefore, each frame portion constituting the upper panel 11 can be made of a resin injection-molded product or cut from a resin plate, and the manufacturing cost of the upper panel 11 can be suppressed. .. However, if the upper panel 11 is formed of resin, the strength of the upper panel 11 is lowered. In this regard, in the animal invasion prevention laying panel 10 of the tenth embodiment, as shown in FIGS. 15 and 16, the upper side is formed by fitting the metal reinforcing pipe 13 into each grid α of the upper panel 11. The panel 11 is designed to exert its strength.

As the reinforcing pipe 13, a pipe having an outer peripheral shape having a shape following the inner peripheral shape of the lattice α is usually used. In the animal invasion prevention laying panel 10 of the tenth embodiment, since the inner peripheral shape of the lattice α is rectangular, the reinforcing pipe 13 has a rectangular outer peripheral shape. As a result, the reinforcing pipe 13 can be firmly held in the grid α in a state where the reinforcing pipe 13 is tightly fitted in the grid α. Such a reinforcing pipe 13 can be obtained at low cost by cutting a long metal pipe to a predetermined length.

As described above, in the animal invasion prevention laying panel 10 of the tenth embodiment, when the upper panel 11 is formed of resin, the lower panel 12 can also be formed of resin. This is because the stimulating protrusion β provided on the lower panel 12 is not a place where a load such as a pedestrian is directly applied, and therefore is not required to be as strong as the upper panel 11.
