Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small animal intrusion prevention plate to be installed in a structure into which small animals can enter, and a laminated structure using the same.

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

Due to frequent replacement and expansion of cables, such as replacement due to depreciation deadline of information equipment and replacement due to performance improvement of information equipment, we prepared a large duct-shaped case outside the building and installed it inside one after another. and increase the number of cables.

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

These cables and pipes are routes that small animals such as rats, palm civets, raccoons, and weasels can climb up by holding on to the cables and pipes and move vertically from the basement of the building to the upper floors above ground. It has become. Small animals include not only four-legged small animals such as rats, but also birds and the like.

However, there was no device that could prevent the movement of small animals in the space for cables and pipes in the vertical direction caused by these vertical shafts and ducts. This resulted in me wandering around.

In addition, it is now possible to wander freely in the horizontal direction of the conventional attic and under the floor space of an intelligent building.

Rats have a habit of growing their incisors and other teeth continuously, so they have to chew hard things and wear down their teeth. Resulting in. Therefore, they have a habit of chewing on hard objects soon after birth.

Due to the situation of ducts such as cables and pipe spaces in vertical shafts, small animals freely enter buildings, and in the case of railways, information equipment such as control rooms, signal stations, and substation rooms are damaged by small animals. It caused various problems such as trains stopping, and at the Fukushima nuclear power plant, a cooling system could not operate due to an electric leakage caused by a rat, resulting in a meltdown.

On highways, problems may occur in the ETC charging system. In addition, in wooden structures such as houses, electrical leakage fires occur and are always among the top causes of fires. In addition, in a company, the entire company will stop functioning due to a system failure.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a small animal intrusion prevention plate and a laminated structure that can prevent small animals from wandering freely or freely entering a space to be protected. and

In order to solve the above problems, the present invention employs the following means.

It is a front view of a small animal invasion prevention plate. FIG. 2 is a schematic cross-sectional view of a pipe introduction structure using a small animal invasion prevention plate; FIG. 10 is a front view showing an example of the usage state of the pipe introduction structure using the small animal invasion prevention plate. Fig. 2 is a front view of a screw receiving member containing reinforcing fibers; FIG. 10 is a perspective view showing a usage state of the pipe introduction structure using the small animal invasion prevention plate.

Hereinafter, 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 plate 1 for preventing small animal intrusion is preferably made of metal with a thickness that satisfies the necessary strength so as not to be broken by the biting force of the target small animal's teeth and the force of the neck. More specifically, stainless steel can be selected as a material that is resistant to rust and, at the same time, is resistant to ultraviolet rays. However, even stainless steel with a thickness of less than 0.6 mm is easily bent by rats, so the thickness is preferably 0.6 mm or more. Similarly, even aluminum will bend like a mouse if it is less than 1 mm thick. Therefore, it is a material that is made of metal and has a strength that can not be bent, and if it is a civet or a wild boar, a thicker necessity may arise. In addition, as shown in FIG. 1, the plate 1 for preventing entry of small animals has a plurality of perforations 10 that are two-dimensionally and regularly arranged based on standard dimensions. The small animal intrusion prevention plate 1 has a vertical width of about 100 mm and five width sizes.

In addition, the shape of the perforated portion 10 is circular in the example shown in FIG. It may be a quadrangle, an equilateral triangle, an isosceles triangle, a triangle such as a right triangle, a polygon including a regular polygon such as a regular pentagon or a regular hexagon, an ellipse, or an indefinite shape.

The small animal invasion prevention plate 1 has a first surface 11 (see FIG. 3) and a second surface 12 opposite to 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 partial regions of the first surface 11 and the second surface 12 . The perforations 10 are staggered with respect to other adjacent perforations 10 . In this zigzag arrangement, it is preferable to set the angle formed by one of the perforations 10 and two adjacent perforations 10 to approximately 60 degrees.

In the small animal invasion prevention plate 1, the plurality of perforations 10 preferably have substantially the same diameter (eg, 4.5 mm).

In the small animal invasion prevention plate 1, as shown in FIG. 1, a first folding line L1 and a second folding line L2 are defined along a direction substantially perpendicular to the vertical direction, and a mountain fold is made at the first folding line L1. and a concave bottom portion 14 that is valley-folded along the second folding line L2. In FIG. 1, reference numerals L1, L2, 13, and 14 indicate only the small animal intrusion prevention plate 1 having the smallest width, but the other small animal intrusion prevention plates 1 have the same configuration. be.

In the plate 1 for preventing intrusion of small animals, a convex top portion 13 is provided on the upper portion and a concave bottom portion 14 is provided on the lower portion. It is also easy to match, 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 are formed by folding back the stainless steel plate so that the sides that come into contact with the cable C can be rounded, thereby preventing the cable C from being damaged.

Specifically, control rooms and signal stations related to transportation systems, such as locations along railway lines and facilities on expressways, are subject to constant shaking of about 3 on the Japanese seismic scale due to the operation of vehicles, etc., so small animal intrusion prevention plates are installed. Safety is maintained by rounding the contact surface between 1 and the cable.

FIG. 3 is a front view showing an example of the 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 to be passed through the oblong perforation may be different in thickness. Being able to freely use it at various angles can improve the convenience of closing.

FIG. 4 is a front view of the screw receiving member 2 containing reinforcing fibers. Reference numeral 2 indicates a portion for attaching the rat-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 for receiving screws for fixing the rat-proof plate. , and reference numeral 21 indicates a portion for introducing a cable. In the preliminary investigation stage, the number, number, volume, etc. of the existing pipes are measured, and depending on the type and amount of thickness, etc., avoiding in advance, as shown in FIG. We will prepare a typical opening and change it according to the circumstances of each site.

FIG. 5 is a perspective view showing how the pipe introduction structure using the small animal invasion prevention plate 1 is used. Even if the plate 1 for preventing intrusion of small animals is piled up, since the perforated portion of the round hole is present at the same position of the screw receiving member 2 containing reinforcing fiber, if the plate is piled up and screwed, a large amount can be stored. At this time, the rat-proof plate is screwed into the wooden part of the laminated structure through the circular hole-shaped perforation part 10, but even if the screw is pulled out and inserted in the same place many times, the plate 1 for preventing small animals from entering is firmly received. It plays a role in preventing it from falling out even if you pull it with your mouth. For that purpose, three layers of waterproof plywood are used, and glass cloth is sandwiched between the two layers. Glass cloth has excellent properties, and has a higher tensile strength than Viano wire. The plywood is vertically glued to the wood, sandwiched between 36mm, 12mm and 24mm with elastic glue. Therefore, even if it is pulled out and inserted many times, the performance of holding it sufficiently is maintained.

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

In the plate 1 for preventing intrusion of small animals, a first folding line L1 and a second folding line L2 are defined along a direction substantially perpendicular to the vertical direction, and a convex top portion is folded downward along the first folding line L1. 13, and a concave bottom portion 14 that is valley-folded along the second folding line L2 may be provided on the upper portion.
