Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to a device for preventing damage caused to houses by pests such as termites, caterpillars, and ants.

[Prior art] In order to prevent termite damage, which is said to cost tens of billions of yen annually, an organic chlorine-based termite control agent, chlordane (C7θHaCl), is used.
5) Impregnation, painting, spraying, perforation injection into building structural materials, or spraying around fabric foundations with 2% to several% oil or emulsion is most commonly used, and the control effect is also reliable and large. has been done.

By the way, house termites are a pest that invades houses and causes significant damage. House termites build their nests in the ground, connect to houses above ground through tunnels, climb up from the foundation to the wood surfaces of houses, create covered tunnels, and devour the wood. These house termites nest in the soil far away from the damaged area, so
Nests are difficult to eradicate.

[Conventional problems to be solved by the present invention] Currently, chlordane, which is widely used as a termite control agent, is an organic chlorine and is harmful to humans and livestock, so care must be taken when handling it. In recent years, it has been frequently reported that trace amounts of chlordane, which is not used for anything other than termite control, has begun to be detected in bays, lakes, marshes, well water, etc. in various places. Unexpectedly, chlordane, which was thought to be chlordane, flowed into groundwater and, to make matters worse, chlordane is non-degradable and decomposes semi-permanently so that it does not lose its insecticidal effect for a long time even if it penetrates into the soil. As a result, it has been forced to be reconsidered as a cause of environmental pollution such as water pollution.

The present inventor has developed a pest prevention member in which a groove-shaped casing is horizontally fixed to a house, and the casing is filled with a medicinal substance for pest extermination to prevent damage from pests.

In order to prevent pests from entering the house, pest prevention members need to be fixed all around the foundation without any gaps, and the barrier grooves need to be filled with poison or contact agent.

By the way, when using a drug like chlordane, which maintains its medicinal effect for a very long time without being decomposed, pests can be exterminated by spraying it directly into the soil under the bed, but the drug sprayed into the soil Not only does it stay under the floor for a long time, but it can also be washed away by rainwater, etc., and get mixed into vegetables in the fields and drinking water, causing serious harm to the human body. Furthermore, no matter how long the medicinal effect lasts, it cannot stay under the floor forever and is washed away, so pests cannot be exterminated unless the medicinal agent is sprayed at regular intervals.

Therefore, chemicals such as chlordane, which does not decompose for a long time, are sprayed under the floor every few years, and the amount used annually across the country has risen to an enormous amount, and it has been reported that even animals in Antarctica have been affected by chlordane. .

Medicinal agents have been developed that decompose in the soil and lose their medicinal efficacy in a short period of time, but the duration of their medicinal efficacy is so short that they are of little practical use unless they are sprayed on the foundation using a special method.

The present inventor has achieved extermination of pests using a chemical that decomposes in the soil in a short period of time by fixing a barrier groove to the foundation and filling the barrier groove with a chemical.

However, even with this method, the medicines filled in the barrier grooves do not stay there forever; they are blown away by strong winds and disappear, or they absorb moisture in the air, resulting in a decrease in the efficacy of the medicines after several years. was there.

[Object of the present invention] The present invention has been developed with the aim of further eliminating these drawbacks, and an important object of the present invention is to provide a structure that can be easily and quickly fixed to the foundation of a building. In particular, it is an object of the present invention to provide a pest control member for houses that allows easy replenishment of chemicals.

Another important object of the present invention is to provide a pest control component for houses that retains its medicinal efficacy for a long period of time.

[Means for achieving the purpose] A pest control device for a house is an upper opening that is continuously fixed in a horizontal or nearly horizontal extension along the foundation of the building and is filled with an insecticide to prevent the entry of pests. A barrier body having a barrier groove, and a barrier groove located on the outside of the barrier body so as to cover but not close the opening of the barrier groove of the barrier body! It consists of a waterproof cover and a water-resistant cover. The barrier body has a locking piece located above the barrier groove to which the cover is locked,
On the other hand, the cover has a locking piece that is hooked on the locking piece of the barrier main body, and the interlocking piece is hooked to attach the cover to the barrier main body with a removable mark.

[Operations and Effects] The barrier body is fixed to the foundation, and the cover is secured to the barrier body. The cover is detachably attached to a locking part provided above and along the barrier groove of the barrier body. It is provided. Therefore, the cover can be attached very easily by simply locking onto the engaging portion of the barrier body fixed to the foundation. For this reason, a pest control member with a complicated structure with a cover can be fixed to the foundation simply and easily, and furthermore, since the opening of the barrier groove is covered with the cover while the cover is fixed, the cover can be fixed easily and quickly. It can prevent the medicine filled in the barrier groove from being blown away by the wind, and it can also prevent rainwater etc. from entering the medicine, and by using easily degradable medicine, it can be effectively preserved for a long period of time to maintain its medicinal efficacy. It can be connected for a long time, and when filling the drug, the cover can be removed to open the groove, making it easy to fill the drug.

Furthermore, when replenishing the medicine every 5 to 10 years, for example, the cover is removed and the medicine is replenished. Therefore, the work is easy, maintenance is easy, and the barrier grooves provide reliable medicinal efficacy over a long period of time, making it possible to effectively exterminate pests.

[Preferred embodiment] Embodiments of the present invention will be described below based on the drawings.

The pest control device for a house shown in FIG. 1 includes a barrier body 2 fixed to a foundation 1, a cover 9 attached to the barrier body 2, and a fixed cover 9 fixed to a foundation 5.

The barrier body 2 includes a connecting portion 4 attached to the upper surface of the foundation 1, and barrier grooves 3, which are barrier portions, provided on both sides of the connecting portion 40. The connecting portion 4 and the barrier grooves 3 on both sides are

It is formed to have a width equal to or wider than the thickness D of the foundation 1, thereby connecting the barrier grooves 3 on both sides in parallel.

Further, the connecting portion 4 is preferably formed in a sheet shape that covers the entire upper surface of the foundation 1. The connecting portion 4 in this state also has the effect of blocking the passage of moisture between the concrete foundation 1 and the wood foundation 5, thereby preventing the foundation 5 from rotting due to moisture.

Although not shown in the drawings, the connecting part 4 that covers the entire upper surface of the foundation 1 has a bolt hole drilled in line with the position of the bolt that fixes the foundation to the foundation 1 at the time of installation, and this bolt hole is connected to the bolt fixed to the foundation 1. Insert and secure.

The barrier grooves 3 on both sides of the connecting part 4 are formed in a groove shape with an upward opening so that an insecticide can be filled therein.

After the barrier body 2 is fixed to the foundation 1, the barrier groove 3 is filled with insecticide 8.

Insecticide 8 includes not only poisonous substances that kill pests when eaten, but also contact agents that kill insects when they come into contact with them.
Or all insecticides that are carried by ants to their nests, where they are eaten and the pests are killed. Let's eat! l! ! Insecticides in all forms can be used, such as powdered, paste, or granular forms made by mixing foods such as honey with chemicals such as oxalic acid.

In addition, insecticides that do not kill pests, but which pests hate and do not pass through, can also be used.

The barrier main body 2 shown in FIG. 1 is formed with barrier grooves 3 having different sizes on the outdoor side and the indoor side.

The barrier main body 2 shown in FIG. 3 has locking grooves 12 on both sides of the connecting part, and a separately molded barrier groove 3 is fitted into the locking groove 12 on the outdoor side to form a large barrier groove 3. A cover 9 is attached to the engagement groove 12 on the indoor side.

The locking groove 12 is formed by the locking piece 7 that covers the locking piece 6 of the cover 9, and is provided above the barrier groove.

A cover 12 is fitted into the locking groove 12, and the cover and the barrier body 2 are fixed via a locking piece 6.9.
