Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building having an insect-proof or antiseptic structure for preventing damage of insects such as termites or preventing corrosion of bacteria and the like for a long period of time.

[0002]

2. Description of the Related Art Buildings require considerable expense for termite control. The reason is that the operator dives under the floor to spray the medicine, and further, drills a hole in the base to inject the medicine. This method loses its efficacy after a certain period of time. To lengthen the duration of the drug effect, considerably tighter drugs are used. This is because chemical treatment cannot be performed again because of the high costs required for termite control. Severe drugs can harm the health of workers who go under the floor, and also put residents living in drug-treated buildings at risk of phytotoxicity.

[0003] In order to prevent this adverse effect, a building has been developed which takes measures against termites during construction. A simple structure is to sandwich a rug filled with a termite-controlling agent between the foundation and the base (Jpn.
No. 107 and Japanese Utility Model Application Laid-open No. 60-135342).
Buildings of this construction can be easily constructed, but it is difficult to effectively eliminate termites over many years.

[0004] As a structure for effective termite extermination over a long period of time, a building capable of injecting a chemical between a base and a foundation after construction has been developed (Japanese Utility Model Application Laid-Open No. 56-5481 and Japanese Utility Model Application Laid-open No. 2-56). 134106). The buildings described in these publications are plumbed along the base or where necessary. The medicine can be applied to the required part by injecting the medicine into the piping. Therefore, there is a feature that termites can be reliably exterminated by injecting a chemical into the pipe at regular intervals. In particular, the structures described in these publications can easily inject a drug, so that there is no need to use a hard drug, and there is also a feature that drug damage can be reduced.

However, it is difficult for the structure described in the above-mentioned publication to accurately spray a medicine on a necessary portion. A piping structure that can frequently spray a medicine does not require the use of a tight medicine, and thus has the advantage of reducing drug damage. However, it is important to reduce the phytotoxicity and use the drug effectively. That is, it is important to apply a small amount of the medicine accurately to a necessary portion. In the same way that termites are harmed, it takes time to prevent bacteria from growing and corroding wood, such as foundations.

The present inventor has sought to solve this problem.
A building having an insect repellent or antiseptic structure shown in FIGS. 1 and 2 has been developed (Japanese Patent Laid-Open No. Hei 7-102653). In the building of this figure, a medicine groove 4 is provided along the upper surface of the base 2. The medicine tube 3 is provided in the medicine groove 4. The drug tube 3 has a nozzle 5 for injecting a drug into the drug groove 4 of the base 2. The medicine tube 3 is connected to a medicine filling device 11,
The medicine supplied from the filling device 11 is supplied to the medicine groove 4 of the base 2. The medicine supplied to the medicine groove 4 permeates the base 2. Further, in order to supply a medicine between the base 2 and the foundation 1, a medicine injection hole 7 is provided in a vertical direction of the base 2 at predetermined intervals connected to the medicine groove 4. A water-absorbing material 8 that penetrates the medicine supplied from the injection hole 7 is sandwiched between the base 2 and the foundation 1.

[0007] In the building of this structure, the medicine is supplied to the base 2 as described below. The medicine filling device 11 is connected to the medicine tube 3. The medicine is injected into the medicine tube 3 by the medicine filling device 11. The medicine injected into the medicine tube 3 is supplied to the nozzle 5 of the medicine tube 3.
And the medicine is supplied to the medicine groove 4 and the injection hole 7. The medicine in the medicine groove 4 flows down the base 2 through the injection hole 7 and permeates the wooden base 2 from the surface of the injection hole 7. The chemical that has flowed down through the injection hole 7 is impregnated in the water absorbing material 8 sandwiched between the base 2 and the foundation 1, and is diffused between the base 2 and the foundation 1 by the water absorbing material 8. Since the water absorbing material 8 is in contact with the lower surface of the base 2, the agent is uniformly applied to the lower surface of the base 2. The base 2 is likely to be in a wet state at the boundary with the foundation 1, which is an environment favorable for the propagation of Fusarium. Fusarium fungi prefers the cellulose of wood and propagates in humid areas. Termites prefer to eat the breeding parts of Fusarium. Since the water-absorbing material 8 is laid between the base 2 and the foundation 1 and a chemical is supplied to the water-absorbing material 8, it is possible to effectively prevent the propagation of Fusarium head blight and the damage of termites.

[0008]

The building shown in FIG. 1 has a feature that the base can be effectively prevented from being damaged by termites and the like. However, there is a disadvantage in that it is difficult to replenish the entire base with the medicine. Although a large amount of medicine is supplied to a portion near the filling device, there is a disadvantage that it is difficult to sufficiently supply the medicine to a portion distant from the filling device. If a large amount of medicine is replenished so as to sufficiently supply the medicine to a location remote from the filling device, there is a problem that a large amount of medicine overflows from the medicine groove near the filling device. The supply amount of the medicine can be adjusted by adjusting the size and number of the nozzles. A small number of small nozzles are provided near the filling device, and a large number of large nozzles are provided at a portion remote from the filling device, so that the supply amount of the medicine can be adjusted. However, in practice, it is extremely difficult to uniformly supply the medicine to the entire base with this structure. In particular, small nozzles are prone to clogging due to the fine injection holes, and it is extremely difficult to eject a designed amount of drug over a long period of time. Also, if a clogging occurs in the middle of the drug tube, overflow occurs, and it is extremely difficult to remove the clogging. This is because disassembling the drug tube is extremely troublesome and almost impossible. Furthermore, the building having the structure shown in FIG. 1 has a drawback in that a chemical groove is provided on the base and a chemical pipe is connected to the base by connecting the chemical pipe to the base. . In particular, construction is difficult at the corners, and the drug tube is likely to be clogged in this area.

The present invention has been developed with the object of overcoming this drawback, and an important object of the present invention is to provide a simple and convenient method for supplying a medicine to a base in an ideal state. An object of the present invention is to provide a building having an insect repellent or antiseptic structure and a base used for the building, the structure of which can reduce construction costs.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment described below exemplifies a building having an insect-proof or antiseptic structure for embodying the technical idea of the present invention and a base used for this building, and the present invention relates to a building and a base for the base. The structure is not specified as:

Further, in this specification, in order to make it easy to understand the claims, the numbers corresponding to the members described in the embodiments are referred to as "claims" and " In the column of “Means of the above”. However, the members described in the claims are not limited to the members of the embodiments.

The insect-proof or antiseptic building shown in FIG. 3 and the base 2 used for this building are exemplified as those which prevent termite harm. It goes without saying that by changing the drug, the harm of pests other than termites can be prevented, and furthermore, the preservation due to bacteria and the like can be prevented. A medicine introduction path 10 is piped to a base 2 fixed on the foundation 1, and a termite medicine is applied to the base 2 through the medicine introduction path 10. The foundation 1 is made of concrete, and the upper surface on which the base 2 is placed is made flat. The base 2 is wooden and the anchor bolt 1
It is fixed to the foundation 1 via 2.

For example, the width and depth of the medicine introduction path 10 are as follows.
It can be 10 to 30 mm. The base 2 fixed to the base 1 is preferably provided with a drug introduction passage 10 in its entirety, in order to prevent all parts from harm of termites. In a building having a base on which the medicine introduction path 10 is provided as a whole, the medicine can be injected from the medicine introduction path 10 to all the bases 2 to exterminate termites. However, parts that are less susceptible to termites, for example, parts that are particularly air-permeable and dry, or parts of the base 2 that are made of plastic or concrete instead of wood are not necessarily insect-proof or antiseptic. Therefore, it is not necessary to provide the drug introduction path 10 in such a portion.

The base 2 fixed to the foundation 1 is composed of a plurality of square members 9. As shown in the cross-sectional view of FIG. 4, the base 2 includes a square bar 9A forming an upper part and a square bar 9B forming a lower part. The upper square bar 9A has a medicine groove 4 on the lower surface.
Are provided, and the opening of the medicine groove 4 is closed with a square bar 9B and adhered. The closed medicine groove 4 is used as a medicine introduction path 10 penetrating in the extension direction of the base 2, and the base 2 is insect-proofed and preserved by injecting a medicine into the medicine introduction path 10. Chemical groove 4 of square bar 9A
Can be grooved at a factory before construction, or can be grooved on site before the base 2 is fixed to the foundation 1.

Wood such as cedar, cypress, and pine is used for the upper square bar 9A. These timbers are relatively inexpensive, readily available, and easy to process, making them ideal as architectural timbers. Further, since the specific gravity is light and the density is not high, it has a property of absorbing moisture well. For this reason, a medicine can be absorbed well and insect repellency and antiseptic property can be provided. Square lumber 9
A having a total length of about 4 m is usually used. Square lumber 9
The lower surface of A, that is, the surface to be bonded to the square
A medicine groove 4 is provided along the extension direction in parallel with the long side of A. The medicine groove 4 can be easily provided by cutting off the surface of the square member 9A before bonding the square member 9B. Drug groove 4
May be provided only in one article, but a plurality of articles may be provided. The square material 9A having the plurality of drug grooves 4 has a large contact area between the medicine and the square material 9A when injecting the medicine, and can supply the medicine to the base 2 in a wider range, and the medicine permeates the base 2. The area becomes large and the insect repellent and preservative effect can be enhanced. The square bar 9A shown in FIG. 4 has the drug groove 4 as two lines. The interval between the parallel medicine grooves 4 is, for example, 5 cm. Square material 9A provided with two drug grooves 4 in parallel
As shown in the vertical sectional view of FIG. 5, horizontal grooves 10A are provided at regular intervals between drug grooves 4 arranged in parallel. The medicine groove 4 shown in FIG.
Even if the medicine groove 4 is partially clogged, the medicine can be circulated without stopping the flow of the medicine because the lateral groove 10A can bypass the medicine.
The medicine can be circulated without delay by the lateral groove 10A, and the medicine that flows smoothly penetrates into the square material 9 efficiently.

The lower timber 9B is made of Karin, Reddish, Kusunoki,
Wood that is resistant to decay, such as litter pine and chestnut , is used. Since the square lumber 9B located on the lower surface is required to have strength, it is optimal to use wood that has a high specific gravity, is hard, does not easily rot, and can withstand long-term use. However, these woods are durable, but difficult to process, expensive, and have drawbacks that are difficult to obtain as square materials of about 4 m in length that can be used as building materials. Many trees such as litter pine have bent trunks and branches, and when cut out as 4 m square wood, the yield is extremely poor.

The building having the insect repellent or antiseptic structure of the present invention and the base used for this building can be reduced in cost by dividing the base 2 into a plurality of square members 9 and using expensive wood and inexpensive wood in combination. be able to. As shown in FIG. 4, durable wood is used for the lower square bar 9B, and easy-to-process wood is used for the upper square bar 9A, and the ratio between them is, for example, 7: 3. The base 2 is strengthened by arranging a durable square bar 9B at the lower portion, and the square bar 9A at the upper portion facilitates processing, thereby facilitating connection with columns, beams, and the like, and processing for combining square bars. I do.

Further, as shown in FIG. 5, a building having an insect-proof or antiseptic structure according to the present invention and a base used for this building have a lower square member 9B having a width equal to that of the upper square member 9A and a total length equal to that of the square member 9A. Is also shortened, and is adhered to the lower surface of the upper square bar 9A to form one base 2. For example,
If the total length of the lower square bar 9B is 1 m to 2 m and the upper square bar 9A is 2 m to 6 m, two or three lower square bars 9B can be bonded to the lower surface of one upper square bar 9A. If the lower timber 9B is shortened, even a deciduous tree having a bent trunk or branch can be used as a raw wood, so that the timber 9B can be obtained from a single tree with a good yield, and it can be easily obtained at a low cost. . Further, by adjusting the ratio of the upper rectangular member 9A to the lower rectangular member 9B, the demand for the lower rectangular member 9B can be reduced and the base 2 can be made inexpensive. Furthermore, wood such as pine litter can be warped over time, deforming columns and other dimensions and causing dimensions to go out of order, but by dividing it into short square timbers 9B, the merit that deformation can be minimized. There is also.

The upper square bar 9A can also be divided. Although not shown, in the case of dividing the upper bar 9A, the lower bar 9 is divided in the vertical direction and divided in the horizontal direction.
The adhesive strength with B can be prevented from being reduced. Each of the upper rectangular members 9A divided in the vertical direction can be provided with a drug groove 4, but the medicine groove 4 is provided on the contact surface between the rectangular members 9A, and the work of providing the grooves can be simplified. By cutting off the corners on the side where the upper rectangular member 9A is bonded to the lower rectangular member 9B on each of the bonding surfaces of the upper divided rectangular members 9A, the medicine groove 4 can be formed by bonding the upper and lower rectangular members 9A. . According to this method, the medicine groove 4 can be configured only by dropping the corners of the individual square members constituting the upper square member 9A, and the step of providing the grooves can be further simplified.

The medicine groove 4 through which the medicine flows is provided in the upper square member 9A which is easy to process. The medicine groove 4 is not provided in the lower square member 9B. However, a medicine groove can also be provided in the lower square member 9B corresponding to the medicine groove 4 of the upper square member 9A. Also,
It is also possible to provide a medicine groove in the lower square member 9B without providing the medicine groove in the upper square member 9A. In this case, it is necessary to cut off the surface of the hard square bar to provide a groove. In the case where drug grooves are provided in both the upper and lower square members, it is necessary to adjust the positions so that the respective drug grooves are connected. Therefore,
The medicine groove 4 is provided only in the upper square 9A, and the lower square 9
If the chemical groove 4 is not provided in B, it is not necessary to perform complicated processing on hard wood, and the operation can be simplified.

The medicine groove 4 is not provided in such a manner as to make a hole from the end face of the base 2 to the center with a gun drill. Before laminating the square 9, the surface of the square 9A that is easy to process is cut off, and the opening is later closed with another square 9B to form the drug groove 4. , Much easier and easier. The medicine groove 4 can be provided in the process of manufacturing the base 2 by making use of the characteristic that the base 2 is composed of a plurality of square members 9.

The medicine supplied from the medicine groove 4 penetrates from the inside of the base 2 toward the external surface.
The medicine can be supplied more reliably than the method of spraying the medicine to the outside. In the upper square bar 9A, insects and antiseptic are brought into contact with the medicine in a wide area where the medicine groove 4 is provided. In the bottom of the square timber 9B, the drug groove 4 from the surface of the sealed portion narrowing seen drug immersion, it will penetrate downward. The lower box 9B has a thinner cross section than the upper box 9A, and also has a property of being hard to rot. Therefore, even if the area in contact with the medicine is small, there is an insect repellent and antiseptic effect.

The size of the drug groove 4 is, for example, 1.5 c
m, width of about 1 cm, so that the width of square material 9 is 10 cm
Even so, the area occupied by the drug groove 4 in the bonding surfaces of the upper and lower square members 9 can be made sufficiently small, and the upper square member 9A and the lower square member 9B can be firmly bonded without any problem. As shown in the cross-sectional view of FIG. 4, the upper bar 9A and the lower bar 9B are firmly fixed with a phenol-based adhesive. The phenolic adhesive is strong, and even if the contact area of the square bar 9 is slightly lost by cutting the drug groove 4, the upper square bar 9 is hardly a problem.
A is bonded to the lower square bar 9B. The base 2 is fixed to the foundation 1 through an anchor bolt 12.

A water absorbing material 8 is sandwiched between the lower rectangular member 9B and the foundation 1. The water-absorbing material 8 accumulates the chemical supplied to the inside of the base 2 from penetrating to the lower part, prevents the chemical from flowing and being lost, impregnates the chemical, and has a long-term insect repellent and antiseptic effect. Hold. However, the base 2 can be fixed to the foundation 1 without providing a water absorbing material. As the water absorbing material 8, any material that absorbs the medicine supplied from the medicine groove 4 can be used. As the water absorbing material 8, a nonwoven fabric, paper, cloth, or an inorganic foam foamed into open cells, which is durable and does not corrode, is optimal. A nonwoven fabric in which plastic fibers are three-dimensionally assembled is inexpensive, durable, and excellent in water absorption of a drug. The inorganic foam has sufficient compressive strength and excellent durability. The inorganic foam has such a strength that it does not deform even if it is sandwiched between the base 2 and the foundation 1, and has a feature that a considerably large amount of drug can be absorbed by the water absorbing material 8 that is not crushed. By providing a non-foamed layer on both sides of the open-celled inorganic foam, it is possible to prevent the medicine from drying and disappearing from both sides. Non-woven fabric that aggregates fiber materials,
Although not shown, the surface of the water-absorbing material 8 such as paper or cloth is covered with a waterproof member so that the medicine can be prevented from drying. A plastic sheet can be used for the waterproof member.

The base 2 composed of a plurality of square members 9 can be formed into an I-shape, T-shape, L-shape, cross-shape or the like by combining the bases. As the structure for connecting the square members 9 constituting the base 2, any of the conventionally used connection structure and the connection structure to be developed can be used. For example, a connection structure called a finger as shown in FIG. 8 can be used. Also at the part connecting the square members 9, one of the square members 9 A is attached to the other square member 9 A in order to make the medicine groove 4 continuous.
Is provided with a lateral groove 10A for connecting to the medicine groove 4 of the first embodiment. As the lateral groove 10A, the same structure as the lateral groove 10A that bypasses the drug grooves 4 running in parallel shown in FIG. 5 can be used. In other words, a lateral groove 10A that bypasses the parallel drug grooves 4
Can be used for bridging with the drug groove 4 provided in another rectangular member 9A orthogonal to the rectangular member 9A.

For example, when assembling the base 2 into an L-shape as shown in FIG. 3, a lateral groove 10A as shown in FIG. The lateral grooves 10A have the same size, width, and number so as to be continuous with the longitudinal medicine grooves 4 of the other square member 9A at the time of connection.
It is provided so as to be orthogonal to the drug groove 4. At this time, unlike the transverse groove 10A for the bypass, the length of the transverse groove 10A is not only between the medicine grooves 4, but at least one of the transverse grooves 10A is opened through the medicine groove 4 to the surface of the square member 9. To extend. This is for connecting the extended lateral groove 10A and the medicine groove 4 of the other square member 9A. In the base 2 of FIG. 5, two transverse grooves 10A penetrate the two drug grooves 4 on both sides and are orthogonal to each other, and the vertical and horizontal drug grooves 4 are connected at four locations via the transverse grooves 10A. The position at which the lateral groove 10A is provided varies depending on how the base 2 is assembled.
If it is connected to the end of A in a T-shape or an I-shape, it will be the center of the square bar 9A. Preferably, the lateral grooves 10 are previously set in accordance with the pattern for connecting the base 2, such as both ends and the center of the square bar 9A.
If A is provided at a fixed position or at an interval, positioning at the work site is simplified. Alternatively, a lateral groove 10A may be provided in advance as a bypass, that is, only between the drug grooves 4, and the transverse groove 10A of a necessary part may be extended and connected at the time of work, or the rectangular material 9 The opening of the lateral groove 10A that is not used at the time of connection can be closed with the plug 13, and the lateral groove 10A is almost formed in any method, so that the working efficiency is improved. Can be done.

Since the end of the groove 9A provided with the lateral groove 10A is opened on the surface of the square 9, this portion is closed with a plug 13. The stopper 13 seals the opening on the surface of the square bar 9 to prevent the medicine from leaking from the opening. The plug 13 is preferably made of the same material as that of the square member 9A, and has the same insect repellent and antiseptic effect as the other parts of the square member 9A without deteriorating the aesthetic appearance, and is in the same state as the part without the plug. The size of the stopper 13 is almost the same as or slightly smaller than the cross section of the opened drug groove 4 so that the drug groove 4 can be sealed by being driven into the opening. The plug 13 can be firmly driven into the opening so as not to come out again, but as shown in FIG. 6, a part or all of the plug is provided with a flange 13a at one end so that it can be freely inserted and removed. Can also. The opening plug 13A of this structure is driven into the opening, and is closed.
Since the protrusion 3a protrudes from the surface of the square member 9, the stopper 13A can be pulled out by grasping the flange 13a, and the closed medicine groove 4 can be opened.

In order to supply the medicine to the medicine introduction path 10,
An open plug 13A that can open at least two plugs is provided. This is because the medicine is injected from the opened medicine introduction path 10, the medicine is taken out from one end, and supplied to the entire base 2. In order to circulate and supply the medicine, one opening is a medicine supply port 15 and the other is a discharge port 16. A plurality of opening plugs 13A which can be opened can be provided at a plurality of positions to change the medicine supply section. However, as shown in FIG. 7, a supply port 15 and a discharge port 16 are provided with a pump 17 for circulating a medicine.
Since these need to be connected, they are provided in the vicinity. Further, in order for the drug introduction path 10 connecting these to circulate through the entire base 2, it is necessary to block the shortest course of the drug introduction path 10 connecting the supply port 15 and the discharge port 16. For this reason, it is desirable that the positions of the supply port 15 and the discharge port 16 be determined in advance at positions where the pump 17 can be easily arranged. The stopper 14 is used to connect the medicine introduction passage 10 before connecting the square member 9.
To be packed. Alternatively, this portion may be structured so as not to be opened from the beginning. At the portion where the medicine introduction path 10 is sealed and the square member 9 is connected, the adhesive surface is caulked so that the medicine is completely adhered so that the medicine does not leak, so that there is no gap in the adhesive surface. When the square member 9 is brought into close contact with the caulking material, the rear end of the stopper 14 may be protruded with the front end of the stopper 14 inserted into the opening of the square member 9, and the connection may be performed in a dowel shape to position the bonded state.

The medicine is circulated through the medicine introduction passage 10 by the pump 17 to prevent the foundation of the building from insects and preservation. As shown in FIG. 7, the pump 17 has nozzles on the discharge side and the suction side, sends out a drug for insect control or preservation from the discharge nozzle 18, sucks in the drug from the suction nozzle 19, and supplies the drug while circulating. . The medicine has an insect repellent action, an antiseptic action, or an insect repellent and antiseptic action. The medicine is filled in a medicine tank (not shown) connected to the pump 17 and circulated by the pump 17. Supplied to the base 2.

In order to supply the medicine to the base 2, the following is performed. With the opening plug 13A of the base 2 pulled out, the medicine introduction path 10 is opened. The opening plug 13A is pulled out at two locations, one of which is a drug supply port 15 and the other is a discharge port 16. Drug introduction route 1
0 is opened at the supply port 15 and the discharge port 16 and the supply port 15
And the discharge port 16 are continuous through the entire base 2. The medicine introduction path 10 is not the whole base 2 circularly connected, but is the shortest path between the supply port 15 and the discharge port 16,
Blocked by 4.

The discharge nozzle 18 of the pump 17 is connected to the supply port 15 of the base 2, and the suction nozzle 19 of the pump 17 is connected to the discharge port 16 of the base 2. These connecting parts are sealed via a nipple 20 to prevent the drug, which has been pressurized by the pump 17, from leaking.

The medicine tank is refilled with medicine. The pump 17 is operated to flow the medicine into the circulating medicine introduction path 10, and supplies the medicine while circulating the medicine through the base 2. If the medicine is merely poured into the medicine introduction path 10, the liquid concentrates in a part such as below the base 2 and it is difficult to supply the whole medicine. However, the circulation in which the medicine is injected from one side and discharged from the other side. By supplying as a state, the base 2
Can uniformly penetrate the drug.

The time for circulating the medicine depends on conditions such as the size of the building and the medicinal effect. For example, the pump 17 is operated for 2 to 4 hours, and during this time, the user is asked to refrain from entering and leaving the building. Since the medicine can be supplied only by operating the pump 17, the operation itself is extremely simple. The supplied medicine also flows only to the necessary part and does not leak out from the circulation path, so that the influence on the human body can be minimized.

After the medicine is sufficiently filled, the pump 17 is stopped and the nozzle is pulled out from the opening. The opening of the base 2 is closed again with the opening plug 13A. This completes the operation, and when the medicine is to be supplied again several years later, the medicine can be easily supplied many times by removing the opening plug 13A and connecting the pump 17 similarly.

The building having the insect repellent or antiseptic structure according to the present invention and the base used for this building are capable of efficiently supplying chemicals from the inside of the base and effectively preventing termite and bacterial damage with a small amount of chemicals. It has the feature that almost no phytotoxicity can be caused to the residents living in the insect- or preservative-treated building.
This is because the building of the present invention supplies the medicine in a circulating state to the medicine introduction passage provided inside the base. Even if the medicine is sprayed on the outside of the base, the amount absorbed by the base is limited, and most of the medicine remains on the surface without being absorbed, and flows along the surface into the soil. The drug that flows into the soil is
Pollutes groundwater, which has a negative impact on drinking water and the natural environment. Furthermore, if you try to increase the insect repellent and preservative effect,
Large quantities of more powerful drugs are required, which adds to costs and risks to workers. In addition, a drug having a strong effect harms the worker and the resident and the environment even after the work.
The building having the insect-proof or antiseptic structure of the present invention and the base used for this building supply the medicine from the inside of the base through the medicine through the medicine introduction passage provided inside. Therefore, since the drug penetrates from the inside, the drug is efficiently supplied to the base, so that a large amount of the drug is not required, and a small amount of the drug can be used for preservation and insect control without waste. Also, because the drug is injected directly into the base instead of being supplied through a dedicated piping pipe,
The drug is absorbed by directly contacting the inner surface of the drug introduction path, that is, the wood. In addition, by giving the drug in a circulating state, penetration is promoted, and the drug can penetrate the entire base evenly through the base of the wood. Drugs that have definitely penetrated
Insects and preservatives effectively over many years. Further, since the drug does not remain outside, the safety is extremely high as compared with the conventional one. The phytotoxicity of the inhabitants living in the insect- or preservative-treated building can be reduced to a minimum. in this way,
The medicament can be used without waste for the purpose of controlling insects or preserving, which is the original purpose, and the harm to surroundings can be eliminated.

In addition, a remarkable feature of the present invention is that a building having an insect repellent or antiseptic structure and a base used for the building can be constructed very simply and at low cost.
No matter how safe and efficient it is, it is difficult to realize it with expensive equipment. The base of the present invention can greatly simplify the step of providing a drug introduction path inside.
This is because the base is made up of a plurality of squares, a drug groove is provided on the bonding surface between the squares, and this opening is closed with the squares to form a drug introduction path. In addition, a lateral groove is provided in the medicine groove to facilitate connection between the medicine introduction paths on the base, and at the same time, it has a function as a bypass for smooth circulation of the medicine. If this method, such as work to accurately drill holes in the fixed position of the cross section of the base with a gun drill, or work to pipe the pipe that supplies the drug,
There is no need to perform difficult and time-consuming and difficult steps. In order to provide the medicine introduction path, it is only necessary to cut off the surface before bonding the square pieces, and since the medicine introduction path can be formed at the same time as the square pieces are bonded, it is very easy to perform.

Further, by dividing the base into upper and lower parts, it is possible to use wood that is easy to process as the upper timber and strong timber as the lower timber, and to provide ideal characteristics as a base. A chemical groove is provided in wood which is easy to process to further simplify the work, and since it has a property of easily absorbing a chemical, it can be hardly rotted with a preservative, and the weakness of rot resistance can be covered. The lower part is a solid timber that stabilizes the base, and strong timber is costly, so only the lower part is used, and low-cost timber can be combined with the upper part to reduce costs. Further, if a plurality of short squares are used as the lower square, and the lower squares are bonded to the upper squares, the price can be further reduced and easily obtained. Furthermore, the disadvantage that the hard wood is significantly deformed over time can be minimized by connecting a plurality of short timbers. As described above, the wood having different properties is skillfully used to produce the wood having the ideal characteristics that can be used for the building having the insect-proof or antiseptic structure of the present invention and the base used for this building at extremely low cost. be able to.

The building having the insect repellent or antiseptic structure of the present invention and the base used for this building have the advantage that the work can be easily carried out even for extermination of termites generated on pillars under the floor. In such a case, it is usually necessary for the worker to go under the floor and spray the medicine directly on the pillars one by one. This is very troublesome and bad for your health. Due to the small space under the floor, it must be in an unreasonable posture, and the burden is placed on the waist, making it difficult to work. In addition, direct spraying of insecticidal drugs can be somewhat absorbed by the body and harm health, and there are concerns about the adverse effects of residual drugs. In addition, the amount of the drug sprayed on the surface of the column is absorbed by the column in a small amount, and flows down the surface, so that the drug stays on the column for a short time and has a limited duration. Furthermore, there is a problem that the chemicals flowing down from under the floor soak into the soil and contaminate the groundwater. The building having the insect repellent or antiseptic structure of the present invention and the base used for this building can be configured so that the opening plug protrudes from the surface of the pillar to open the medicine introduction passage. For this reason, even in the work under the floor, the opening plug is pulled out, the medicine introduction path provided in the pillar is opened, and the medicine may be filled with a thin pipe or the like from here, so the work is extremely simple, And it can be done safely. There is no need to spray the drug on other unnecessary parts, it is safe for the environment, and since the drug penetrates the entire pillar from inside, the drug efficacy is enhanced and the features that can eliminate termites reliably are realized.
