Description

TECHNICAL FIELD The present invention relates to a mounting structure for a small animal invasion prevention material.

In recent years, computers have made everything in the world, including companies and governments. One of the things that bring down the computer society is bites by rats. For example, at the Fukushima nuclear power plant, NHK news reported that a charred rat had fallen, and that the cooling system did not work. It is said that the meltdown could have been prevented had the cooling system operated normally.

Rats have a habit of continuously growing front teeth called incisors. If you don't do this, your teeth will continue to grow, your mouth won't close or open, and you'll starve to death. I can't stop with that habit.

Even if the building is super high-rise, even in a wooden house, electrical wiring is fixed under the floor or in the ceiling. The underfloor and ceiling are non-residential spaces. This uninhabited space is sometimes inhabited by rats, which can chew on computer wiring.

DETAILED DESCRIPTION OF THE INVENTION Embodiments for carrying out a mounting structure for a small animal intrusion prevention member to which the present invention is applied will now be described in detail with reference to the drawings.

The attachment structure 1 of the small animal intrusion prevention material according to one embodiment of the present invention prevents target small animals from entering the gap space under the floor between the concrete floor surface of the structural frame and the floor material on which people walk. is a mounting structure for a small animal intrusion prevention material that covers the The mounting structure of the present invention can be used both under the floor and above the ceiling, but below, the case where it is installed under the OA (Office Automation) floor in recent office buildings and the like will be described.

As shown in FIGS. 1 to 4, the mounting structure 1 of the small animal entry prevention material includes a small animal entry prevention material 2, a pair of fixtures 3 fixed to the concrete floor surface, and these pair of fixtures 3 are connected. A back plate 4 is provided.

The small animal intrusion prevention material 2 is provided in a part under the floor of the OA floor which is not usually seen. For example, the small animal entry prevention material 2 is provided in an 8.5 cm portion of the underfloor. The area between zero and 8.5 cm between such an underlying concrete floor and the human living space is where it is necessary to prevent, for example, rats from running around, chewing on cables, etc. .

The small animal intrusion prevention material 2 is made of so-called sheet metal, which is formed by bending a metal plate having a thickness that satisfies the necessary strength not to be broken by the biting force of the teeth of the target small animal or the force of the neck. . More specifically, stainless steel can be selected as a rust-resistant material. 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.

As shown in FIGS. 1 to 4, the small animal intrusion prevention member 2 is provided between a substantially rectangular small animal intrusion prevention plate 20 and a pair of fixtures 3, and is located at the lower end of the small animal intrusion prevention plate 20. and a folded portion 21 that is folded upward from the . Between the lower end portion of the folded portion 21 and the concrete floor surface, a gap is formed through which the wiring is passed. Here, the dimension of the gap is preferably 7 mm. Here, most of the floor surfaces of the building are made of concrete. Floors are often uneven. Some are even uneven. In such a case, some unevenness is contained within the range of error of 7 mm, and the small animal invasion prevention material 2 is greatly inclined, and the small animal invasion prevention material 2 cannot be attached to the floor material. I never get chilled out. In other words, this 7 mm dimension provides a tolerance for irregularities. In addition, this 7 mm dimension prevents mice from passing through, maintaining the rat-proof function.

As shown in FIGS. 1 to 4, the pair of fixtures 3 has a substantially rectangular shape in plan view, and five holes 30, which are joints with the concrete floor surface, are opened in an X shape. is provided. A known adhesive can be used for joining.

As shown in FIGS. 1 to 4, the back plate 4 is pre-drilled with a screw hole 40 that penetrates in the thickness direction and serves as a base point. The width of the screw hole 40 is preferably 4 mm to 5 mm. In the example shown in FIG. 1, the shape of the screw hole 40 is an oval shape extending vertically in a plan view, but it is not particularly restrictive in the present embodiment. The advantage of the oval shape is that even if the unevenness of the floor surface and the lower part of the indoor flooring, that is, the height to which the small animal invasion prevention plate 20 is raised, the operator can easily match it with the left hand. It is possible. The back plate 40 is provided with a contact portion 41 that contacts the lower side of the floor surface of the OA floor. As a result, the underfloor gap between the concrete floor surface of the structural frame and the floor material on which a person walks is closed, and the target small animal is prevented from entering the gap.

The plate 20 for preventing intrusion of small animals is provided with screw holes 20 a having substantially the same shape corresponding to the screw holes 40 provided in the back plate 4 . The width of the screw hole 20a is preferably 2 mm. This is because the time required for attaching the small animal invasion prevention material 2 to the floor material can be shortened. The 2 mm dimension is suitable for any drilled screw dimension and is easy to bite into.

The small animal intrusion prevention member 2 and the back plate 4 are integrated by hiss-fixing the screw holes in a state of being aligned at a predetermined angle.

In the following, the operation of attaching the small animal invasion prevention member 2 to the floor material will be described by taking a right-handed worker as an example. The operator holds, for example, an electric screwdriver in the right hand, holds the plate 20 for preventing entry of small animals in the left hand, and holds it on the lower side of the floor material, which is at the same height. At this time, the pair of fixtures 3 are adhered to the floor without being touched by the operator.

At this time, the operator attaches a drilled screw to the tip of the electric screwdriver, but it does not move because the pair of fixtures 3 are already adhered. Therefore, even when the operator holds the plate 20 for preventing entry of small animals with the left hand, the operator can quickly tighten the plate by pressing the drilled portion of the electric screwdriver with the right hand against the drilled portion. This allows the work to be completed quickly. If you get used to it, you can attach the small animal invasion prevention material 2 to the floor material in a short time of about 2 seconds.

In addition, if the pair of fixtures 3 on both sides of the small animal entry prevention material 2 are provided not only in two places as in this embodiment, but in three or more places, the small animal entry prevention material 2 is tilted. This is because the small animal intrusion prevention member 2 cannot cope with unevenness and is affected by the unevenness of the concrete floor surface. In this regard, in this embodiment, since the fixtures 3 are provided only at two locations on both sides of the small animal invasion prevention material 2, the pair of fixtures 3 straddle like a bridge, so there is no problem. Cables and wiring can be included.

In addition, since the predetermined height is 7 mm, even if many cables and wiring have already been installed when the worker goes to the site, the cables and wiring can be included inside the bridge, so the installation work can be carried out smoothly. can be implemented smoothly without any problems.

In addition, this 7 mm height is the limit that the parent of a mouse cannot pass through, and it is the maximum size that can not be passed, including other mice, and can prevent the invasion of mice. .

This 7 mm portion corresponds to the folded portion 21 and has a folded structure. That is, since the tip portion of the folded portion 21 is rounded, even if the tip portion comes into contact with a cable or wiring, it will not be damaged.

In addition, the screw holes 20a of the small animal intrusion prevention plate 20 are formed in a 2-mm oval shape in the back, and the screw holes 40 in the back plate 4 are formed in a 4- to 5-mm oval shape in the front. This is based on the following reasons (a) to (d).
(a) This is because the width of 2 mm makes it possible to bite into the tip of a screw for metal and to screw it in immediately. In general, it cannot be said that a screw bites well in a round hole.
(b) Because of the oval hole, the screw can be screwed in at the height to be stopped in an instant while pulling up the anti-intrusion material on the top corresponding to the back plate 4 with the left hand. In the case of a round hole, it cannot be stopped at a position that just fits the height.
(c) If you are right-handed, hold the top anti-intrusion plate corresponding to the back plate 4 with your left hand, and hold an electric screwdriver in your right hand. be.
(d) As a result, labor productivity will be extremely high.

Although the attachment structure of the member for preventing entry of small animals of the present invention has been described above based on the embodiments, the specific configuration is not limited to this embodiment, and can be set forth in each claim of the scope of claims. Design changes, additions, etc. are permitted as long as they do not deviate from the gist of the invention.

Here, in the above-described embodiment, if each cable is laid on the floor surface or in the ceiling, there is no problem because it can be enclosed in the gap below 7 mm. However, if a plurality of thin cables are bundled together, or if cables or wiring with a thickness exceeding 7 mm are laid, the gap of 7 mm cannot be used.

Therefore, on-site workers have to consider the thickness and size of the material and cut it with metal scissors.

A mounting structure for the small animal invasion prevention material for that purpose will be described below (see FIGS. 5 and 6). Regarding the thickness of the small animal invasion prevention material, since it is cut only by the grip strength of the worker with metal scissors, for example, the thickness of the iron material can be about 0.5 mm.

As shown by the dotted line, make a cut line with gold scissors, bend it as shown in the figure, and bend the part that contacts the cable at a right angle or more to prevent damage to the cable.

The holes 30 (five-hole adhesive surfaces) like the pair of fixtures 3 are not provided. Even if it is expensive, it can be handled.

As shown in FIG. 7A, when the small animal invasion prevention plate 20 is added in a direction 180° with respect to its longitudinal direction, a substantially rectangular connection plate 5 can be used. It is preferable that a gap of 7 mm is formed between the lower end of the connection plate 5 and the concrete floor surface for the wiring to pass through. A fixture 50 having an L-shaped cross section and being fixed to the concrete floor is provided at substantially the center of the connection plate 5 .

As shown in FIG. 7(B), the connection plate 6 can be used when the small animal invasion prevention plate 20 is added in the direction of 90° with respect to the longitudinal direction. The connection plate 6 consists of a left side 60 , a central part 61 and a right side 62 . The central portion 61 is provided with a fixture 61a having an L-shaped cross section and fixed to the concrete floor surface. A longitudinally extending line of the left side portion 60 and a longitudinally extending line of the right side portion 62 intersect at an angle of 90°. It is preferable that a gap of 7 mm is formed between the lower end of the connection plate 6 and the concrete floor surface for the wiring to pass through.
