Description

The present invention relates to a small animal invasion prevention plate installed in a structure capable of invading small animals and a laminated structure using the same.

The information society caused by computers these days is managed and operated by digital information. Therefore, a large number of cables such as wirings and cables (hereinafter referred to as cables) between information devices are often connected over multiple floors such as the upper and lower floors of a building.

Due to frequent cable replacement and expansion, such as replacement of information equipment due to depreciation deadline and replacement due to performance improvement of information equipment, large duct-shaped cases are prepared outside the building and one after another. And the result is an increase in cables.

In addition, in the building, wiring and piping related to the lifeline of the building such as water pipes and gas pipes introduced from the basement are concentrated in the pipe space installed near the vertical such as elevators and emergency stairs. It is installed on the upper and lower floors.

These cables and pipes can be climbed by small animals such as rats, palm civets, raccoons, and weasels by holding them on the cables and pipes, and move vertically from the basement of a high-rise building to the upper floors above the ground. It has become. The small animals include not only small four-legged animals such as mice but also birds and the like.

However, since there was no device that could prevent the movement of small animals in the space such as cables and pipes in the vertical direction caused by these vertical lines and ducts, small animals could freely move in the vertical direction by using vertical lines and ducts. The result was that I was wandering around.

Moreover, it is now possible to freely wander in the lateral direction of the conventional attic and the underfloor space of an intelligent building.

Mice have a habit of continuing to grow teeth such as incisors, and they have to bite hard objects to wear them, and if this is not done, the mouth will not close or the mouth will not open, resulting in starvation. Resulting in. Therefore, they have a habit of chewing hard objects shortly after birth.

Due to the situation of ducts such as cables and pipe space of vertical railroads, they can freely invade the building, and in the case of railways, damage caused by small animals to information equipment such as control rooms, signal stations, and substations occurs. It is a new case in my memory that the cooling system at the Fukushima nuclear power plant could not operate due to the occurrence of electric leakage caused by mice, causing various problems such as the train stopping, resulting in a meltdown.

On highways, problems may occur in the ETC billing system. In addition, in wooden structures such as houses, electric leakage fires occur and are always the top cause of fires. In addition, in a company, a system down causes a company-wide outage.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a small animal invasion prevention plate and a laminated structure capable of preventing small animals from freely wandering or freely invading a space to be protected. And.

The present invention employs the following means in order to solve the above problems.
The small animal invasion prevention plate according to the present invention is a small animal invasion prevention plate installed in a structure capable of invading small animals, and has a first surface and a second surface on the opposite side of the first surface. Then, a plurality of perforations penetrating from the first surface to the second surface are formed in at least a part of the first surface and the second surface, and the perforations are formed in other adjacent perforations. On the other hand, it is characterized by a staggered arrangement.

Further, in the small animal invasion prevention plate according to the present invention, in the staggered arrangement, it is preferable to set the angle formed by one of the perforated portions and two perforated portions adjacent thereto to approximately 60 degrees.

Further, in the small animal invasion prevention plate according to the present invention, it is preferable that the plurality of perforated portions have substantially the same diameter.

And a concave bottom portion that is valley-folded at the second folding line.

Further, the small animal invasion prevention plate according to the present invention is made of a metal having a thickness that satisfies the necessary strength that is not destroyed, such as the tooth biting force and the neck force of the target small animal. preferable.
Further, it is a laminated structure used when screwing a screw into a wooden portion through the perforated portion of the small animal invasion prevention plate according to the present invention, and is one surface of a first plywood and the first plywood. A second plywood formed on the side of the second plywood, a third plywood formed on the other side of the second plywood, and a second plywood formed between the first plywood and the second plywood. 1 glass cloth, a second glass cloth formed between the first plywood and the third plywood, and
It is preferable to provide.

According to the present invention, it is possible to prevent small animals from roaming freely or freely entering the space to be defended.

It is a front view of the plate for preventing small animal invasion. It is the schematic sectional drawing of the pipe introduction structure using the plate for preventing small animal invasion. It is a front view which shows an example of the use state of the pipe introduction structure using the small animal invasion prevention plate. It is a front view of the screw receiving member containing a reinforcing fiber. It is a perspective view which shows the use state of the pipe introduction structure using the small animal invasion prevention plate.

In the following, a pipe introduction structure using a small animal invasion prevention plate as an example according to the present disclosure will be described with reference to the drawings.

FIG. 1 is a front view of a small animal invasion prevention plate. The small animal invasion prevention plate 1 is preferably made of a metal having a thickness that satisfies the necessary strength that is not destroyed, such as the tooth biting force and the neck force of the target small animal. More specifically, stainless steel can be selected in consideration of the property of being resistant to rust and at the same time being resistant to ultraviolet rays. However, even if it is stainless steel, if the thickness is less than 0.6 mm, the mouse easily bends, so the thickness is preferably 0.6 mm or more. Similarly, even aluminum is bent by a mouse if its thickness is less than 1 mm. Therefore, it is a material that is made of metal and has strength that cannot be bent, and if it is a palm civet or a wild boar, a thicker need may arise. Further, as shown in FIG. 1, the small animal invasion prevention plate 1 has a plurality of perforations 10 that are two-dimensionally and regularly arranged based on the reference dimensions. The small animal invasion prevention plate 1 has a vertical width of about 100 mm and a horizontal width of five sizes.

The shape of the perforated portion 10 is circular in the example shown in FIG. 1 in a plan view, but is not particularly limited in the present embodiment, and other shapes such as a rectangle, a diamond shape, and a parallel quadrilateral shape are used. It may be a quadrangle, a regular triangle, an isosceles triangle, a triangle such as a right-angled triangle, a polygon including a regular polygon such as a regular pentagon, or a regular hexagon, an ellipse, or the like, or an indefinite shape.

The small animal invasion prevention plate 1 has a first surface 11 (see FIG. 3) and a second surface 12 on the opposite side of the first surface 11. The perforated portion 10 is formed so as to penetrate from the first surface 11 to the second surface 12 in at least a part of the first surface 11 and the second surface 12. The perforations 10 are staggered with respect to the other adjacent perforations 10. In this staggered arrangement, it is preferable to set the angle formed by one of the perforated portions 10 and the two perforated portions 10 adjacent thereto to approximately 60 degrees.

In the small animal invasion prevention plate 1, the plurality of perforated portions 10 preferably have substantially the same diameter (for example, 4.5 mm).

In the small animal invasion prevention plate 1, as shown in FIG. 1, a first fold line L1 and a second fold line L2 are defined along a direction substantially perpendicular to the vertical direction, and a mountain fold is formed at the first fold line L1. It is preferable to include a convex top portion 13 to be formed and a concave bottom portion 14 to be valley-folded along the second folding line L2. In FIG. 1, reference numerals L1, L2, 13, and 14 are shown only for the small animal invasion prevention plate 1 having the smallest width, but the same configuration is used for the other small animal invasion prevention plates 1. is there.

By providing the convex top 13 at the top and the concave bottom 14 at the bottom of the small animal invasion prevention plate 1, even if the shape is not constant, such as a bundle of cables, how can each cable condition be met? It is easy to match with, and cable construction is easy.

FIG. 2 is a schematic cross-sectional view of a pipe introduction structure using a small animal invasion prevention plate. As shown in FIG. 2, the convex top portion 13 and the concave bottom portion 14 can be rounded on the side in contact with the cable C by folding back the stainless steel plate, and damage to the cable C can be prevented.

Specifically, control rooms and signal stations related to transportation, such as locations along railroad tracks and facilities on highways, are constantly shaken with a seismic intensity of about 3 due to the operation of vehicles, etc., so small animal intrusion prevention plates Safety is maintained by making the surface of contact between 1 and the cable rounded by folding back.

FIG. 3 is a front view showing an example of a usage state of the pipe introduction structure using the small animal invasion prevention plate. As shown in FIG. 3, the thickness of the cable C through which the perforated portion of the oval is passed may be different, and the cable C may be slanted or upside down in order to prevent the invasion of small animals. Since it can be used freely at various angles, the convenience of closing can be improved.

FIG. 4 is a front view of the screw receiving member 2 containing reinforcing fibers. Reference numeral 2 indicates a portion for attaching the rodent-proof cable introducer to a concrete surface or the like and round holes for anchor bolts at the four corners, and reference numeral 20 indicates a mounting portion of a laminated structure member that receives screws for fixing the rodent-proof plate. , And reference numeral 21 indicates a portion into which the cable is introduced. Measure the quantity, number, volume, etc. of existing pipes at the preliminary investigation stage, avoid them in advance depending on the type and amount of the thickness, etc., and as shown in FIG. 4, the part with respect to the screw receiving member 2 containing reinforcing fibers. We will prepare a specific opening and change it according to the circumstances of each site.

FIG. 5 is a perspective view showing a usage state of the pipe introduction structure using the small animal invasion prevention plate 1. Even if the small animal invasion prevention plates 1 are stacked, since there is a perforated portion of a round hole at the same position of the screw receiving member 2 containing reinforcing fibers, if the plates 1 are stacked and screwed, a large amount can be stored. At this time, the rat-proof plate is screwed into the wood part of the laminated structure by the round hole-shaped perforated portion 10, but even if the screw is inserted and removed at the same place many times, it is firmly received and the small animal invasion prevention plate 1 Even if you pull it in addition to it, it plays a role in stopping it so that it will not come off. Therefore, a waterproof type plywood is used for three layers, and a glass cloth is sandwiched between the two layers. Glass cloth has very excellent properties and has stronger tensile strength than Viano wire. The plywood is vertically glued with wood, sandwiched between elastic adhesives at 12 mm and 24 mm positions for 36 mm. Therefore, sufficient holding performance is maintained no matter how many times it is inserted and removed.

Although the small animal invasion prevention plate of the present invention has been described above based on the embodiment, the specific configuration is not limited to this embodiment, and the invention according to each claim of the claims is not limited to this embodiment. Design changes and additions are permitted as long as they do not deviate from the gist.
