Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a means for controlling termites that cause food damage to buildings, and more particularly to a termite control material and a termite control structure.

[0002]

2. Description of the Related Art Termites that cause damage to buildings intrude into a wooden member that serves as a food, mainly through an ant road formed from an underground nest to the outside. Therefore, in order to prevent the feeding damage of such termites, a specialist has taken measures such as placing or spraying under the floor a drug having eating and contact toxicity to termites.

Further, the applicant of the present application discloses the termite control device for preventing the invasion of the termites in Japanese Utility Model Publication No. 4-7309 and Japanese Utility Model Publication No. 4-30271, and exhibits the required effects. FIG. 7 is a block diagram of the above-mentioned ant-prevention apparatus. As shown in the figure, this ant-prevention apparatus is equipped with a base 52 mounted on a boulder 51 placed on the ground below the floor, and a Standing support bolt 53
And a bolt hole 54a to be screwed with the tip of the support bolt 53
And a flat plate-shaped dovetail plate 55a, 5 that is inserted into the support bolt 53.
5b is horizontally fixed by a nut 57 at a substantially intermediate position between the base 52 and the floor bundle receiver 54.

The above termite control device achieves control by utilizing the following termite life. That is, since termites generally have a poor water-retaining ability in the body, the distance that they can move without replenishment of water is at most about 1 m, and the above-mentioned ant-prevention plates 55a and 55b move the ant road from the bundle stone 51 toward the floor bundle 56. The termites attempting to invade while forming are detoured beyond the limit of the movable distance so that they cannot reach the floor bundle 56, thereby preventing the invasion.

Further, the present applicant has disclosed another termite control device in Japanese Utility Model Publication No. 4-8164, which is shown in FIG. This ant-prevention device, as shown in the figure,
For example, a flexible surrounding plate 61 such as a thin metal plate is curved, and receiving holes 6 are formed at both ends of the surrounding plate 61.
By inserting the fixing pin 62 into 1a and 61b, a cylinder surrounding the bundle 71 and the floor bundle 72 is formed. In the space W between the enclosing plate 61 and the slab 71, for example, a bait containing a boron-based anticide mixed with a cellulose material that is termi- ently eaten is filled, and the floor bundle is passed through the slab 71 from the ground. 7
The termites are controlled by the termites trying to invade 2 by eating the poison bait before reaching the floor bundle 72.

[0006]

By the way, as described above, termites are used because they prefer moisture, so that they are used around water, such as bathrooms, toilets, washrooms, and washrooms, or at the entrances where drainage pipes are buried. It is known that, due to water leakage from floors and drainage pipes, such as the above, it prefers to nest in the ground with a relatively high water content.

[0007] Therefore, in order to ensure the control of termites, it is necessary to install some kind of termite control means around the water and the entrance, but the water and the floor of the entrance are generally made of concrete. , Mortar and tiling, it is not possible to apply the termite prevention device shown in FIG.

Further, based on the structure of the termite control device shown in FIG. 8, the termite control agent is directly buried at the same time as the construction of the above-mentioned water supply and the floor surface of the entrance , or the actual construction of Shokai 58-411.
No. 77, which discloses a drug holding recess that can be filled with an anti-termite agent.
Driving an anti-termite stick with a place into the soil,
Charcoal powder and volcano disclosed in Japanese Utility Model Publication No. 63-1108
Underfloor that can be expected to have termite control function by mixing with ash
It is conceivable to embed a pack in which a carbon preservative is packed in a non-woven bag . However, in these configurations, the water penetrates into the burial site to disperse the medicinal component of the termite control agent into the ground, and the termite control effect is diminished in a very short period of time, while the termite control agent can be replaced. You will have to repeat the excavation in order to do so.

Further, there is a risk of contamination of groundwater and soil by the above-mentioned medicinal components, and the embedding of the termite controlling agent has many harmful effects and is difficult to use in reality. As described above, it is the current situation that no effective means can be found for termites nesting underground under the place where a continuous floor surface is formed from the ground, such as concrete, mortar, and tiling.

The present invention has been proposed in view of the above conventional circumstances, and maintains a desired drug effect for a long period of time.
Can be done, and so-called water supply or Thailand
There is no space under the floor, such as the front door of a sticker
It is an object of the present invention to provide a suitable ant-proof material and ant-proof structure for a location .

[0011]

In order to achieve the above object, the present invention employs the following means. That is, FIG.
As shown in Fig. 10, a packaging bag 10 made of an airtight material
In addition, the termite control agent 1 is a termite control material 1 in which a termite controlling agent P is sealed under reduced pressure. Further, as shown in FIG. 3, a dovetail preventive material 1'having a columnar body of which the bottom surface is a right triangle is also desirable.

As the termite controlling material P, it is desirable to use a cellulosic material mixed with a food toxic anticide. In addition, as shown in FIG. 1, a termite-proof structure in which the termite-proof layer 20 in which the termite-proof material 1 having the above-mentioned structure is laid without a gap is buried in the ground under the floor of the building or is arranged on the ground surface. is there. In addition, the dovetail proofing material 1 having the above-mentioned configuration having a bottom surface in the form of a right-angled triangular column is formed so that the two side surfaces that are at right angles to each other are at right angles.
The two sides are the ground and the side of the foundation structure of the building.
It is also desirable to arrange them in the peripheral portion of the ant-preventive layer 20 so as to be in close contact with each other .

[0013]

The material of the wrapping bag 10 constituting the termite control materials 1 and 1'shown in FIGS. 2 and 3 is airtight to the extent that the depressurized state inside can be maintained after the termite controlling agent P is filled. All you have to do is have it. Therefore, in a state where the packaging bag 10 is not damaged, a large amount of water is not allowed to permeate the inside at once, so that the termite control agent P is prevented from being dissipated, and the termite control agent P is packaged at the time of construction. It is easy to handle because it is installed.

The termite controlling material P may be any chemical containing any of food toxicity and contact toxicity, and termites penetrating from the ground will break through the termite control layer 20 formed without gaps. At this time, the lower surface of the packaging bag 10 is broken and comes into contact with the termite control agent inside, and the termite control action is exerted. In particular, when a cellulosic material mixed with an eating toxic anticide is adopted, since termites prefer to eat the cellulosic material, it is possible to surely kill ant even with relatively weak toxicity. Moreover, since the portion of the termite that has been eaten and broken hits the lower surface of the packaging bag 10,
It is difficult for the water penetrating from the ground surface (floor surface) side to come into contact with the termite control material P, and it is possible to maintain the required termite control effect for a long period of time.

Further, since the termite controlling agent P is sealed under reduced pressure, the inside of the packaging bag 10 is filled with the termite controlling agent P without any gaps. When it is buried in the ground, even if it receives a high earth pressure, the internal pressure of the ant-preventing material 1 is balanced on the entire surface of the packaging bag 10, so that the packaging bag 10 will not burst. On the other hand, in the termite control material in which the termite controlling agent P is not sealed under reduced pressure, as shown in FIG. 6, the balance with the earth pressure F is lost at the location where the residual air A is unevenly distributed, and the packaging bag 10 bursts.

Further, as shown in FIG. 3, a termite-proof material 1'having a columnar shape with a bottom surface of a right triangle is arranged so that two sides which are perpendicular to each other are brought into close contact with the foundation structure of the building and the ground. When it is arranged at the peripheral portion of the ant-preventive layer 20, as shown in FIG. 1, the earth pressure F applied in the downward vertical direction causes the force from the central portion of the ant-preventive layer 20 toward the peripheral portion to be the above-mentioned ant-preventive material 1 '.
And the degree of adhesion with the basic structure is increased.

Further, due to the shape and area of the laying area of the ant-preventing layer 20, another ant-preventing material 1 has to be laid in an area slightly wider than the area surrounded by the ant-proofing material 1 '. Even in this case, as shown in FIG. 1, it is possible to lay it so that the end portion of the other termite proof material 1 rides on the slope of the termite proof material 1 ', which allows flexibility in the laying work. .

[0018]

EXAMPLES The present invention will be described below based on examples. FIG. 1 is a vertical side view of an embodiment according to the present invention,
2 and 3 are perspective views of the termite proof material of the present invention, and FIG. 4 is a flow chart showing the work procedure of the present invention.

The termite proof material 1 used in this embodiment is, as shown in FIG. 2, a wrapping bag 10 made of an airtight material.
The termite control agent P is sealed under reduced pressure, and the packaging bag 1 after sealing
No air remains in 0.

The termite control material 1'shown in FIG. 3 has a columnar body having a right-angled triangle as the bottom surface in the state in which the termite controlling agent P is enclosed, and will be described later. In particular, the shape is suitable for being arranged in the peripheral portion of the ant-proof structure.

The bag 10 is made of an airtight material such as polyvinyl chloride or polyethylene. This facilitates handling during construction, which will be described later, and when the termites do not invade, the medicinal effect of the termite controlling agent P is not diffused to the outside, and the natural environment such as groundwater is not damaged.

Although the components of the termite controlling agent P are not particularly limited, in this example, a cellulosic material mixed with a boron-based anticide (edible toxicity anticide) is used, and when termites enter In order to break through the bag 10,
Since the boron-based anticide is surely eaten together with the cellulosic material, even a toxic boron-based anticide has a sufficient anticidal effect. Incidentally, as the termite controlling agent P, besides this, for example, fine powder zeolite mainly composed of contact toxic silicon dioxide can be used.

In this embodiment, the present invention is applied to the termite proof structure formed in the basement of the bathroom, and the termite proof structure was constructed at the same time as the construction of the bathroom in the procedure shown in FIG. That is, first, as usual, the basic ground E excavated to a predetermined depth
The cloth foundation 31 on which the reinforcing bars 32 are erected is formed [Fig.
(a) "Foundation work"].

After that, a block wall 33 in which concrete blocks are piled up is constructed on the cloth foundation 31, and the ant-preventive materials 1 and 1 ′ are arranged on the ground surface in which the inside of the block wall 33 is backfilled so that there are no gaps. Laying is performed to form an anti-termite layer 20 [Fig. 4 (b) "Laying an anti-termite material"].

In the above-mentioned laying work, first, the two sides of the triangular pillar-shaped termite-proof material 1'shown in FIG. 3 are arranged so as to be in close contact with the ground and the block wall 33, and the peripheral portion of the termite-proof layer 20 is arranged. 2 is formed on the region surrounded by the termite proofing material 1 '.
It was carried out by the procedure of arranging a rectangular parallelepiped-shaped termite proof material 1 shown in FIG. As a result, the earth pressure F applied downwardly in the vertical direction causes an external force to act on the ant-preventive material 1 ', which causes close contact with the block wall 33.
You can block the path of termites that crawl up along.

Further, due to the shape and area of the construction surface of the termite proof structure, the termite proof material 1 is wider than the area surrounded by the termite proof material 1 '.
Even if it becomes necessary to lay the above, it is possible to lay it so that the end portion of the other termite proof material 1 rides on the slope of the termite proof material 1'as shown in FIG. Will be more flexible.

Then, after the drainage pipe 41 is piped above the formed ant-preventive layer 20, concrete is poured into the upper layer of the ant-preventive material 1, 1'to form a base layer 42 (FIG. 4). (c) "Concrete pouring"].

At this time, since the termite controlling agent P is filled in the termite-proofing materials 1, 1'without any clearance by the pressure-reducing encapsulation, the pressure applied to the termite-proofing materials 1, 1'from the outside by the concrete, The pressure inside the termite proofing materials 1, 1 ′ was balanced over the entire surface of the packaging bag 10, and the casting of the concrete did not cause the packaging bag 10 to burst.

After the construction in the above procedure, as shown in FIG. 1, the bath 45 is arranged at a predetermined position, the top coat layer 43 is formed on the underlayer 42, and the tile 44 is formed on the top layer 43. Is attached and the bathroom is completed.

According to this embodiment, the termite prevention layer 20 embedded in the lower layer of the underlayer 42 can prevent termites from entering the bathroom. Further, even if there is water that permeates the underlayer 42 or water that leaks from the drain pipe 41, the medicinal effect of the termite controlling agent P does not dissipate in a short period of time, and the dissipation causes contamination of groundwater or soil. No more worrying.

In the above-mentioned embodiment, the termite-proof layer 20 formed by laying the termite-proof material 1 is buried in the lower layer of the concrete underlayer 42. However, as another example, as shown in FIG. Further, the termite proof material 20 can be formed by laying the termite proof material 1, 1'on the ground surface surrounded by the cloth foundation 31 of the building in the same procedure as described above.

In this case, the construction is extremely easy, and since the termite controlling agent P is protected from moisture by the packaging bag 10, abrupt dissipation of the medicinal component is prevented, and the termite controlling effect for many years. Will be demonstrated.

[0033]

As described above, according to the present invention, the termite control material in which the termite controlling agent is decompressed and enclosed in the packaging bag made of the airtight material is spread over the ground or the ground of a predetermined depth. Since it is possible to maintain the termite control function for a long time just by laying it, it is difficult to apply the termite control means. Can effectively control termites even in places where they are located.
