Description

TECHNICAL FIELD The present invention relates to a member for mainly preventing harmful insects such as termites, caterpillars, ants, and 100 feet from entering a house or exterminating harmful insects that live in a house. .

[Prior Art and its Problems] Yamato termites and house termites are pests that invade houses and cause significant damage. House termites build nests in the soil, connect to houses on the ground by a tunnel, and crawl from the foundation to the wood surface of the house to create a covered tunnel and eat trees. It is difficult to eradicate the nest because this termite nests in the soil far away from the damaged part.

As a conventional countermeasure against termites, there is a method of impregnating soil with an oily emulsion such as a DDT emulsion. However, in this method, the drug is vaporized and disappears over time and loses its effect, resulting in a long-term effective insecticidal effect. Can't hold.

Furthermore, a considerable amount of chlordane was used nationwide to control termites. Although chlordane does not decompose for a long period of time and retains its excellent medicinal effect, it penetrates underground and causes secondary pollution, so its use is currently prohibited.

The present inventor, as shown in the transverse sectional view of FIG. 11, adheres the pest guard 2 formed in a groove shape to the foundation 3 of the house and horizontally fixes the pest guard 2 in the medicine groove 5 of the pest guard 2. We have developed a pest prevention member that is filled with a pest control agent to prevent pest invasion.

In the pest guard 2 of this structure, the medicine groove 5 can be connected laterally completely without a gap, and if the termites and the like do not erode the pest guard forever, the ideal pest control effect is enhanced. However, it is impossible to fix the pest guard without any gap in the actual construction and to use the pest guard made of a material that the pests will not break through forever.
Also, the surface of the foundation to which the pest guard is attached is not completely flat and has some irregularities, so as shown in the pest guard on the right side of FIG. 11, there is a gap between the foundation and the foundation during construction. You can In the gap between these, pests will climb to the back of the pest guard, and the pests that invade here will move left and right along the pest guard and search for parts without chemicals, such as the connection part of the pest guard, and the building. Invade inside. Alternatively, as shown by an arrow A, the pest guard is partially broken down to enter the building. Once you start invading the building from one place,
An ant road is created here, and many pests invade one after another, and the medicinal groove cannot prevent the pests from entering.

The present invention was further developed with the object of eliminating this drawback, and an important object of the present invention is that the drug to be filled in the drug groove is supplied to the foundation surface of the building through the side wall of the drug groove. Another object of the present invention is to provide a pest control member for a house that can effectively control a pest that climbs up between a pest guard and a foundation.

Another important object of the present invention is to have a sufficient pest control action even if a gap is formed between the pest guard and the foundation, and construction work of the pest guard and the foundation, and the structure of the pest guard can be simplified. It is to provide a pest control member for a house.

Furthermore, another important object of the present invention is to provide a pest control member for a house, which can easily supply a medicine between the pest guard and the foundation.

[Means for Solving Conventional Problems] A pest control member for a house of the present invention is a device that is horizontally extended and attached to a foundation of a building to control pests, and is fixed to a building to prevent pests from entering. The blocking pest guard has a drug groove, which is filled with a powdered insecticide.

On the side wall that constitutes the drug hole, on the side facing the foundation, a drug hole is bored through itself, and a mounting piece is provided on the back surface of the drug groove below this drug hole. The mounting groove and the foundation form a barrier groove.

The medicine filled in the medicine groove through the medicine hole is filled in the barrier groove on the back surface of the medicine groove.

[Action and Effect] As shown in FIGS. 1 to 3, the pest control member for a house according to the present invention has a drug hole because it is formed on the side wall of the drug groove on the side facing the foundation. The powdered drug filled in the groove is supplied to the back surface of the drug groove through the drug hole. The medicine fed to the back surface of the medicine groove is stored in the pest barrier groove formed by the mounting piece and the foundation. The drug in the barrier groove reliably prevents pests crawling along the foundation. That is, since the barrier groove is provided directly on the surface of the foundation, the pests that crawl along the foundation always pass through the drug in the barrier groove. As shown in FIG. 3, even if the tip of the mounting piece is slightly separated from the surface of the foundation, the chemical fed into the barrier groove from the chemical hole is deposited in the barrier groove to prevent invasion of harmful insects. In this case, however, the medicine leaks to some extent from the gap between the foundation and the mounting piece, but since the medicine leaks along the surface of the foundation, a part of the medicine adheres to the surface of the foundation and the invasion of harmful insects can be prevented.

Therefore, the pest prevention member for a house of the present invention can effectively prevent pests that creep along the foundation. In particular, even if there is a gap between the surface of the base and the drug groove, the drug that wraps around the back surface through the drug hole is stored in the barrier groove formed by the surface of the base and the mounting piece, and this drug is Directly attaches to the foundation to prevent pest invasion. Therefore, even if there is a gap between the drug and the foundation, the pest can be effectively exterminated. Therefore, the pest guard can be easily manufactured and attached, and the pest guard can be easily attached to a slightly uneven foundation, so that the foundation can be easily constructed.

Furthermore, since it is possible to supply the drug to the pest guard through the drug hole simply by supplying the drug to the drug groove, it is possible to realize the simple effect of supplying the drug to the pest guard.

[Preferred Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

The pest control member of the house shown in FIG.
The connecting part 1 is attached to the upper surface of the connecting part 1 and the pest guards 2 provided on both sides of the connecting part 1.

The connecting portion 1 and the pest guards 2 on both sides are integrally formed of synthetic resin.

As shown in FIG. 4, the connecting portion 1 is attached to the upper surface of the foundation 3 and sandwiched between the foundation 3 and the base 4, so that the pest guards 2 are fixed to both sides of the foundation 3. It is formed to have a thickness equal to or slightly wider than the thickness D of 3 so that the pest guards 2 on both sides are connected in parallel.

Further, this connecting portion 1 is preferably, as shown in FIG.
It is formed in a sheet shape that covers the entire upper surface of the base 3. The connecting portion 1 in this state also has an effect of blocking the passage of moisture between the concrete base 3 and the base 4 made of wood, and preventing the base 4 from decaying due to water.

The connecting portion 1 covering the entire upper surface of the foundation 3 is provided with a bolt hole 18 corresponding to a bolt position for fixing the base 4 to the foundation 3 at the time of mounting, and the bolt hole 18 is inserted into the bolt fixed to the foundation 3. To fix.

The pest guards 2 on both sides of the connecting portion have a drug groove 5 that can be filled with an insecticide, and a locking groove 6 provided on the upper part.

The side walls 5A of the drug groove 5 are provided with drug holes H on opposite sides of the base, and a drug piece N is provided on the back surface of the drug groove 5, that is, between the drug groove 5 and the base 3. It is provided.

As shown in FIGS. 2 and 3, the medicine hole H is preferably formed so that the medicine filled in the medicine groove 5 is supplied to the barrier groove B between the medicine groove 5 and the foundation 3. , Is formed so as to communicate with the bottom of the drug groove 5. The hole H can be formed in a circular shape as shown in FIG. 1 or as an elongated slit shape as shown in FIGS. 5 to 7. As shown in FIG. 6 and FIG. 7, the hole formed by overlapping the drug holes H to some extent has a feature that the drug can be uniformly supplied by the barrier groove. However, as shown in FIG. 1 and FIG. 5, even in the case where the drug holes H are formed in spots, by increasing the drug supply amount to the drug grooves 5, the barrier grooves B are almost continuously formed. Can supply drugs.

A mounting piece N is provided on the back surface of the medicine groove 5. The mounting piece N is located below the medicine hole H so that the medicine fed from the medicine hole H is accumulated therein.

The mounting piece N is made of a rubber-like elastic body that deforms when pressed by hand, such as soft polyvinyl chloride resin or natural or synthetic rubber. Therefore, the mounting piece N is made of a material different from that of the member forming the chemical groove 5. The mounting piece N made of soft vinyl chloride can be integrally formed with the pest guard 2 made of hard or semi-hard vinyl chloride. The rubber-like elastic piece N itself deforms along the unevenness of the base 3 and comes into contact with the surface of the uneven base 3 without a gap. Therefore, the leakage of chemicals in the barrier groove B formed by the mounting piece N and the foundation 3 can be reduced, and the invasion of harmful insects can be prevented more effectively.

Further, preferably, as shown in the transverse cross-sectional view of FIG. 2, this mounting piece N is formed such that the tip circle that contacts the base 3 is formed into a tapered blade shape to improve the contact with the surface of the base 3. .

It is preferable that the mounting piece N be adhered to the surface of the base 3 only by attaching the mounting piece N to the entire surface. In order to realize this, one or both of the pest guard 2 and the connecting portion 1 is molded with a rigid or semi-rigid synthetic resin that is elastically deformable, and the mounting piece N is adhered by its own elasticity. As shown by the chain line in FIG. 4, it is preferable to form the interval between the mounting pieces N smaller than the width of the base 3.

By the way, as shown in FIG. 2, the mounting piece N, which inclines downward toward the foundation, has the action of sending the chemicals supplied to the barrier groove B to the surface of the foundation, and prevents pests climbing up along the foundation 3 from occurring. It can be blocked more effectively.

As shown in FIG. 1, the pest control member having the pest guards 2 of the same shape on both sides is fixed to a foundation and the pest guards 2 are provided on both sides thereof.

The pest control member shown in FIG. 1 can also be provided with a large medicine groove 11 in the base 3 by attaching the medicine groove piece 8 as shown in FIG. In this figure, a medicine groove piece 8 is sandwiched in a locking groove 6 located on the outdoor side of the foundation 3.

As described above, in the case where the medicine groove piece 8 is attached, the medicine groove piece 8 can be attached to the outdoor side of the foundation, and the outdoor side surface of the foundation can be filled with a large amount of medicine to prevent the medicine from disappearing due to wind or the like. .

As shown in FIG. 8, the outside surface of the foundation 3 is a mortar 9
Is attached. The chemical groove piece 9 can also be used as a guide for the mortar 9. The outer side 10 of the medicine groove piece 8 is formed in an uneven shape so that pests can easily crawl up, and has a medicine groove 11 which is slightly larger than the medicine groove 5 formed integrally with the connecting portion 1 and has a filled insecticide amount. Can be a lot.

In this way, a substance that can be filled with a large amount of insecticide on the outside of the base 3 can be expected to have a long-term medicinal effect. Further, a cover 12 made of a corrosion-resistant metal plate such as aluminum or stainless steel is fixed to the outside of the chemical groove piece 8.

In the preferred embodiment of the present invention, as shown in FIG. 2, barrier grooves B are formed on both sides of the foundation. Just the 8th
As shown in the figure, by forming the barrier groove B only on the outdoor side of the foundation 3, invasion of harmful insects from the outside can be prevented.

The medicine groove 11 penetrates the medicine groove piece 8 and the hanging portion 2A of the medicine groove piece 8 to form a medicine hole H '. The medicine supplied to the medicine groove 11 of the medicine groove piece 8 passes through the medicine hole H ′ and the barrier groove B.
Is supplied to. The chemical with which the barrier groove B is filled can prevent pests that creep up through gaps such as cracks generated between the mortar 9 and the foundation 3. However, Mortar 9 and Basic 3
In this case, the pest hole and the barrier groove are not necessarily required because the pests that climb along the concrete surface always pass through the pellicle if there is no gap between the pesticide and the pesticide.

In FIG. 8, the cover 12 fixed to the outside is fixed to the base 4 and also serves as a drain, and the lower part is curved slightly inward to prevent invasion of harmful insects and blowing of wind.

The cover material 12 is stretched on the outside of the cover 12, and the space between the cover material 12 and the cover 12 is waterproofed with a sealing material.

Further, the cover 12 is finished to have a smooth mirror surface so that harmful insects cannot slip and climb up.

Since the cover 7 fixed to the inside of the foundation is located in the underfloor compartment, it is made of synthetic resin. Further, the medicine groove 5 inside the base is filled with a smaller amount of insecticide than the outside of the base.
Since the insecticide does not scatter with the wind in the room and there is little air convection, a small amount of insecticide can exert its medicinal effect for a long time.

As shown in FIG. 1, the symmetrical pest control member does not need to be aligned in the direction when it is attached, and can be easily fixed to the foundation.

In addition, as shown in FIGS. 1 and 4, the one in which the drug groove 5 is attached to the base 3 and the drug grooves 5 are fixed on both sides thereof is the easiest to install the drug groove.

However, the present invention does not specify the mounting structure of the drug groove to the shape shown in FIG. It is possible to fix the drug groove 5 on the surface of the base 3 by a method such as nailing or bonding, as shown in FIG. 9, without attaching to the upper surface of the base.

The powdered drug to be filled in the drug groove is not only a poisonous substance that is killed when a pest eats it, but a contact agent that is killed after contact with this pest, or a pest that an ant or the like carries to a nest and eats in a nest. All insecticides that die, for example, organic chlorine agents, organic phosphorus agents, acaricides, arsenic agents, honey and other foods such as honey, which are mixed with chemicals such as oxalic acid, in powder form, liquid form,
Any form of insecticide such as granules and solids can be used.

Further, as the drug, a drug that does not kill the pest but does not pass because the pest dislikes can be used.

In order to fill the medicine groove with the medicine, the pest guard is fixed to the foundation and is filled before the cover 7 is attached. In this case, the medicine is put in an elongated gutter-shaped container and the medicine groove 5 is filled with the medicine, or the medicine is filled with a piston type medicine extruder (not shown). The piston type extruder fills the inside of a piston with a medicine, pressurizes it, and pushes it out from a nozzle at the tip to fill the medicine groove with the medicine.

Furthermore, after 5 to 10 years, in order to fill the medicine groove in the underfloor on the indoor side with the medicine, it is possible to turn the floor and fill the medicine, but the closed underfloor medicine is pressurized with pressurized air. It is also possible to blow and blow the underfloor air with the sprayed drug to suspend the drug and settle it in the air to supply a part of the drug to the drug groove and the barrier groove. In this case, a larger amount of the drug is filled in the drug groove without the cover 7, but even if the cover is fixed, the drug is supplied to the drug groove below the cover together with the air that is stirred under the floor.
