Description

The present invention relates to pest control technology. In particular, it relates to techniques for controlling chatate beetles.

Techniques for exterminating indoor pests include the use of insecticides, fumigation, insect traps, light attraction, and ultraviolet light.
Methods using drugs are not suitable for facilities where drug residue is a problem. Methods using lights or traps cannot exterminate all individuals.
Chatate beetles have been attracting attention as indoor pests in recent years. Chat beetles often appear on old books because they like mold and dust. Their habitat is wide, and they are found in various indoor locations other than tatami mats.
Chatatebugs are a general term for insects belonging to the order Chatatepillars, and there are approximately 1,700 known species in the world. Many of the types found outdoors are winged. Indoors, most of them are wingless and tiny, about 1 to 2 mm long. It is said that this insect got its name because when it lands on a shoji screen, it makes a sound similar to making tea.
All members of the chatate beetle family are small insects with relatively soft bodies and prefer humid conditions. In recent years, with the spread of air-conditioning equipment and improvements in indoor airtightness, it has become easier for condensation and mold to form indoors, leading to an increase in the occurrence of mold-related insects such as chat beetles.
Chat beetles are omnivorous and eat plant debris, pollen, and insect eggs, but they especially like mold and yeast. It is also known as a pest that damages plant and animal specimens, stored food, etc. It also eats old paper and glue, so it can be emitted from books, and in humid rooms, it can also be emitted from wallpaper paste.
The main types known include Kochatate of the Cochatate family, Hiratachatate of the Conachatate family, Katsubushi chatate, Soumen chatate, and Himechatate of the Himechatate family. All of them are insects with a body length of less than 2 mm and have a light brown color.

Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2020-5569) discloses an invention related to a sticky trap for capturing insects, and in particular, a sticky trap suitable for capturing microscopic walking insects such as chat beetles and mites.
Patent Document 2 (Japanese Unexamined Patent Publication No. 2018-172280) discloses a method for exterminating chatter beetles and the like by fumigating using chlorine dioxide gas.
Patent Document 3 (Japanese Unexamined Patent Publication No. 7-63386) discloses that in the disposal process performed after disinfection treatment such as formalin fumigation, the disinfection exhaust control means is set to a differential pressure regulator with the constant air volume device fully closed. A proportional sensitivity changing means that sets the set proportional sensitivity to be smaller than the steady state proportional sensitivity, and a damper that starts fully opening the supply side high airtight damper and the exhaust side high airtight damper at the same time as the constant air volume device is activated. By providing a fully opening means and a proportional sensitivity return means for returning the proportional sensitivity to the steady state proportional sensitivity after a predetermined time has elapsed since the air supply side high airtight damper and the exhaust side high airtight damper were fully opened, the sterile animal breeding room can be improved. Regarding air conditioners used for air conditioning of bio-clean rooms and the like, an air conditioner that can significantly reduce room pressure fluctuations during disinfection exhaust compared to conventional air conditioners has been disclosed.

Control methods using methods such as traps and inducements result in the remaining chatter beetles that cannot be completely exterminated, and there remains a risk that they may contaminate the drugs being manufactured. The purpose of the present invention is to develop a new method and means for exterminating chatate beetles without using chemicals such as insecticides.

The present invention is an invention in which an environment in which it is difficult for chatate beetles to survive has been clarified, and an environment in which it is difficult to survive has been realized using an air conditioning system and a facility configuration. The main configuration of the present invention is as follows.

1. According to the present invention, it is possible to exterminate chatite beetles from architectural facilities without using chemicals by setting an environment for a certain period of time in which selected chatite beetles cannot survive depending on the temperature and humidity.
Since the present invention does not use fumigants or insecticides, it is a method for controlling chatate beetles that is suitable for pharmaceutical facilities where residual chemicals are undesirable, dry food manufacturing facilities, clean rooms, medical facilities, residences of allergic patients, etc.
2. The present invention has made it possible to create a lethal environment for chatter beetles using an air conditioning system. The air conditioning system of the present invention can be provided with a dedicated air conditioner for controlling insects, or can be used in combination with a regular air conditioner. Since we have created a repellent environment in the air conditioning system that makes it difficult for chatate beetles to inhabit, it is possible to maintain an environment that has been exterminated once.
3. In highly airtight buildings, once extermination treatment is performed, it is possible to keep the insects free for a long period of time. By building a building with a multilayered structure and treating the outside space with extermination treatment, it is possible to prevent chatter beetles from entering the inside space.4. It is possible to construct a pest-free facility by air-conditioning the perimeter insect control area (pest control area) formed to prevent insects from entering from outside at pharmaceutical manufacturing facilities, etc., and the inside of the clean room under insecticidal or repellent conditions. can. By controlling the air conditioning to create an environment that suppresses the emergence and establishment of chatter beetles, which are a particular problem among insects, reliable insect control measures can be taken and the risk of pests contaminating products can be reduced.

The present invention clarifies the conditions for exterminating chatite beetles from facilities without using insecticides, and provides a drug manufacturing facility that can exterminate chatite beetles by using an air conditioning system to create a chatite beetle-free environment. be.

In order to clarify the conditions for exterminating the chatate beetles without using insecticides, we controlled the growth environment of the chatate beetles, conducted survival tests, and clarified the conditions under which they would die.
Based on the conditions under which the insects die, we designed a method for controlling the chatate beetles that causes their death, and an air conditioning system and facility design that realizes this control method.

As a result of controlling the growth environment of the chatate beetles through temperature, humidity, time, and presence or absence of food, the conditions under which the chatate beetles die were clarified, as shown in Table 3. Chatate beetles undergo incomplete metamorphosis, and larvae are considered to be as lethal as adults.
In Table 3, there are 12 types, for example, as follows.
15℃・20%・10 days
20℃・20%・8.3 days
・
・
30℃・50%・11.7 days
・
40℃・60%・7.3 days

In addition, it has been confirmed separately that it is killed at 45°C, 60%, 6 hours, and 50°C, 60%, 5 minutes.

By clarifying a method for controlling chatite beetles by treating them under the killing conditions revealed in this test, and incorporating it into the air conditioning system, it is possible to appropriately exterminate chatite beetles from building spaces and create a chatite beetle-free environment. do. The air conditioning system will reflect a program to maintain low humidity and high temperature, and will build an air conditioning system that incorporates conditions that are lethal to chatate beetles. By applying an air-conditioning system that incorporates conditions for killing insects to buildings, it is possible to create an environment free from insects. For buildings, airtightness, multilayer structures such as double layers, and elimination of gaps are effective structures for controlling chatate beetles.

Chat beetles live by getting into the joints and gaps between fittings, or they can invade through gaps, so to increase the ability to control chatate beetles, create a space with a barrier layer (multi-layer structure, external room). By constructing a barrier layer environment (e.g., facilities such as Facilities) and making the environment of the barrier layer a lethal condition, it is possible to prevent intrusion from outside into the facility. Furthermore, by making the environment of a facility (such as a clean room) where chatate beetles are once exterminated as repellent, their inhabitation can be prevented. The avoidance conditions include an air conditioning system that normally operates under conditions of about 20 to 30 degrees Celsius under which work can normally be carried out, and under dry conditions in which the air conditioner dies at 20 to 30 degrees Celsius.

Since there is always a risk of new chatter beetles entering as materials are brought in and out, it is effective to repeatedly carry out pest control treatments to maintain chatter beetle-free conditions.
A sealable space structure is suitable for the space where chatate beetles are to be exterminated. An air conditioning system to control chatate beetles will be applied to this space. In spaces that can be sealed, seal the gaps with seals, etc. to ensure that there are no gaps in the walls or ceiling where chatter beetles can enter and live.
Furthermore, the barrier function can be improved by doubling the sealed space.
If the facility is constructed with multiple layers, the outside can be used as the primary barrier layer.
In a facility to which the present invention is applied, the entire building can be made into a double space, or a part of the building can be made into a double space consisting of a room where a chatterbox is built and a space around the room.

The present invention is suitable for drug manufacturing facilities, dispensing rooms, dry food processing and manufacturing facilities, medical facilities, dry food storage facilities, and grain and powder storage facilities. In addition, it tends to like glue for books, etc., so it can be applied to libraries, library rooms, museums, etc. It can be applied to general residences and offices, and can improve the sanitary environment.

Extermination treatment can be carried out depending on the situation of the facility. In facilities that need to be permanently exterminated, such as drug manufacturing facilities, the rate of extermination can be reduced by 20 to 50% under high-temperature, short-term killing air conditioning and operating temperatures. By setting the humidity to a value between 1 and 2, it is possible to construct a facility where chatate beetles are exterminated with high precision by operating the normal state as a repellent air conditioner.
Chat beetles breed in hot and humid environments (after the rainy season in Japan), so in libraries, etc., they can be controlled by using air conditioning to kill them before the rainy season, during the rainy season, and in the summer, and by using repellent air conditioning during normal times.
For houses, etc., take into consideration the structure, number of floors, sunlight, etc., and take measures depending on the situation, such as increasing the number of treatments in areas with high humidity.

The extermination process can be set to a constant setting at temperatures of about 15 to 30 degrees Celsius. It is appropriate to perform high temperature heating of 40°C or higher in an unattended environment, such as on days when the facility is not in operation. Furthermore, if the facility is not in production at night, extermination treatment can be performed at night at a high temperature of 40° C. or higher. It is suitable to carry out the treatment in a temperature range of 45°C or 50°C, which can be processed in several hours or minutes.

<Survival test of chatate beetles>
1. About Chatate beetles Chatate beetles are the general term for insects belonging to the order Chatatebugs, and there are approximately 1,700 known species in the world. Many of the types seen outdoors are winged, while those seen indoors are wingless and very small with a body length of 1 to 2 mm. It is said that this insect got its name because when it lands on a shoji screen, it makes a sound similar to making tea with a chasen.
All members of the chatate beetle family are small insects with relatively soft bodies and prefer humid conditions. In recent years, as air-conditioning and heating equipment has become more widespread and indoor airtightness has improved, it has become easier for condensation and mold to form indoors. Along with this, the occurrence of fungal-derived insects such as chat beetles is increasing.
Chat beetles are omnivorous and also eat plant debris, pollen, and insect eggs, but they especially like mold and yeast. It is also known as a pest that damages plant and animal specimens, stored food, etc. It also eats old paper and glue, so it can be emitted from books, and in humid rooms, large numbers can be emitted from wallpaper paste.
The main types are known as Kochatate of the Kochatate family, Hirata chatate of the Conachatate family, Katsubushi chatate, Soumen chatate, etc., and Himechatate of the Himechatate family. All of them are tiny insects with a body length of less than 2 mm and have a light brown color. There are about 10 types of chatate beetles known in Japan. A typical example is ``Hirata Chatate'' shown in Figure 1.

Chatate beetles that occur inside buildings are light brown in color, their larvae cluster together, and they prefer humid, dimly lit environments, so they are sometimes mistaken for mites. The overall appearance is soft and weak, and the head is large compared to the body. They damage a wide range of objects, including ancient documents, books, wallpaper, grains, dried noodles, macaroni, cardboard, tatami mats, and mats.
Since it eats mold, anti-mold measures are required, and there is a possibility that it is occurring especially in closets and storerooms where moisture tends to accumulate. In residential units, it is important to dehumidify by opening windows and doors to improve ventilation, drying, and exposing tatami mats to sunlight.
Figure 1 shows the eggs, larvae, and adults of Hirata chatate. The life cycle is that eggs hatch in 9 to 15 days, larvae become adults in 20 to 25 days, adults live for about 2 months, and begin spawning 2 days after emergence.
They often occur in places other than ordinary homes, and can also invade factories and warehouses by adhering to packaging materials such as cardboard boxes. Even in clean rooms, there is a possibility that it can enter along with packaging materials. They may also live in tiny crevices, feeding on mold and other fungi.
In an inhabitation survey conducted in the pharmaceutical room before the growth test, it was found that in rooms where chemically exterminated insects were removed, they were found at joints in the ceiling panels and wall panels, and it was assumed that they would enter from adjacent spaces through gaps in the ceiling and walls. Therefore, it is thought that simply exterminating chatate beetles from the room will not be able to prevent chatate beetles from being mixed into medicines.

2. Survival test (1) Test specifications (a) Test subject: 50 hiratachatate/1 petri dish (b) Growth environment: Under conditions where the temperature and humidity in Table 4 were maintained at constant temperature and humidity, for a maximum of 14 days, They were bred until they died.
The appropriate environment for the Hirata chatate bred for testing was set at a temperature of 25° C. and a humidity of 75%, so the environment was set based on these comfortable conditions.
A waist-high petri dish containing oyster chatate is kept in a constant temperature chamber with temperature and humidity settings. Note that the "humidity" referred to in the present invention is relative humidity.
(c) Feed: Insect feed to which dried yeast has been added. (d) Conditions for confirming mortality: Observe the Petri dish in the thermostat from the outside, and 90% or more mortality is considered to be mortality. After all the insects were knocked down, the insects were placed under comfortable conditions (temperature 25°C, humidity 75%), and if more than 90% of the insects were not moving after 24 hours, they were considered dead.
(e) Number of tests: 3 times

3. Rearing conditions and mortality time Table 2 shows the rearing conditions and the number of days for mortality.
In addition, it has been confirmed separately that it is killed at 45°C, 60%, 6 hours, and 50°C, 60%, 5 minutes.

4. Discussion As a result of controlling the growth environment of Hirata chatate beetles through temperature, humidity, time, and the presence or absence of food, the conditions under which the chatate beetles die were clarified.
It was confirmed that low humidity (dry) conditions kill the plants in a shorter period of time.
It was confirmed that high temperatures kill them in a shorter period of time.
It was confirmed that the seeds died in 2 to 11.7 days under each temperature and humidity environment.
Therefore, the conditions for controlling chatate beetles can be set to be above the set temperature, below the death humidity, and above the number of days after death is confirmed.
In addition, we have confirmed that it will die in 45℃, 60%, 6 hours, 50℃, 60%, 5 minutes, so at 45℃, 50℃, short-term extermination treatment within several hours or minutes. I can do it.

As a result of Table 4, there are 12 control conditions, and Table 5 shows the control conditions that kill the chatate beetles.
In Table 2, the pest control treatment number is displayed in parentheses in the column indicating the number of days required to maintain each temperature and humidity. An example of this can be done as follows.
(i) 15℃ or more, 20% or less, 10 days or more,
(ii) 20℃ or more, 20% or less, 8.3 days or more,
(iv) 25℃ or more, 40% or less, 12 days or more,
(xii) 40℃ or more, 60% or less, 7.3 days or more

<How to control chatate beetles>
This breeding test confirmed that chatate beetles can be eliminated by controlling the temperature and humidity of the environment and maintaining it for a certain period of time.
You can use different conditions depending on the environment you want to exterminate, and you can use combinations of conditions depending on the time of year.

<Facility structure and air conditioning system>
The present invention proposes an air conditioning system and a building facility as a device for controlling temperature and humidity. As an air conditioning system, it can be applied to a variety of facilities by incorporating the conditions for exterminating chatate beetles. The conditions for removing insects built into the air conditioning system are set to insect insect extermination mode.
When extermination is carried out, it takes about 5.7 to 11.7 days at temperatures below 30 degrees Celsius, where humans can normally live, within 2 to 7.3 days at 40 degrees Celsius, within several hours at 45 degrees Celsius, and within a few minutes at 50 degrees Celsius. It dies within a short period of time, making it suitable for short-term extermination treatment.
By setting the environment to humidity conditions that make it difficult for insects to survive at a temperature of about 15 to 30 degrees Celsius, it is possible to keep the normally used room in a repellent state. For example, at 20°C the humidity is 20%, and at 25°C the humidity is 50% or less. Note that in the present invention, relative humidity is employed. Furthermore, it is possible to perform treatments that combine pest control conditions.
The air conditioning system should be set to these conditions or avoidance conditions. After killing at a high temperature, maintaining a predetermined humidity at 15 to 30°C makes it possible to maintain an efficient chatterbug-free environment.
The present invention can be applied to a wide variety of facilities for extermination of chatid beetles, such as pharmaceutical manufacturing facilities, clean rooms, food manufacturing plants, dry food storage facilities, and residences.

This is a facility with a structure that can suppress the occurrence of chatter beetles with high efficiency, and is a facility configured into multiple spaces, each space being airtight and equipped with air conditioning equipment that can be independently controlled. .
As an example of a facility configured in multiple spaces, a schematic configuration 100 of a Chatatemushifree facility is shown in FIG.

An outer peripheral space OR is formed so as to surround the outside of the work chamber CR for medicines, etc. The work chamber CR and the outer peripheral space OR are each formed into airtight spaces.
A CR air conditioner for the work room CR and an OR air conditioner for the outer space OR are provided. Although two air conditioners are shown in the figure, a common air conditioner can be used as long as the work room CR and the outer space OR can be controlled separately and independently. This air conditioner incorporates a chatate beetle control mode.
The outer space OR is designed to prevent chatter beetles from entering the work room CR from the outside, and to prevent chatter beetles that have gotten into the work room CR by adhering to packaging materials, etc. from the walls and ceiling of the work room CR to the outside of the wall This is a space that prevents them from re-invading into the work room CR by multiplying in the ceiling or ceiling.
The work room CR can be applied to facilities such as manufacturing rooms for pharmaceutical products and the like, where the risk of contamination with chatid beetles is required to be extremely low.

The outer space OR can be set to a high temperature of 40°C or higher even when the work room CR is in operation, so extermination conditions should be implemented irregularly or on a two-day cycle to prevent the occurrence of chatate beetles. I can do it. Although the work room CR can implement extermination conditions as appropriate except during operating hours, it is difficult to completely prevent chatate beetles from being brought in by adhering to packaging materials such as cardboard.
In the work room CR, complete extermination is carried out during long periods of rest such as the end of Bon Festival, and during normal periods, extermination conditions are carried out under possible conditions such as on weekends.
Therefore, a space where severe extermination can be performed is provided outside the work room, and a barrier space is provided to prevent the occurrence of chatter beetles and their invasion from the outside.

The fumigation equipment 9 shown in Figure 2 is not a normal equipment, but is used when providing compensation for a facility that has been completely free of chatter beetles from the original facility, or before equipment renewal or restarting after a long period of suspension. This is equipment used to create a chatterbug-free environment.

In a typical building, this multi-space configuration is set up in a space that is separated by floor slabs on the top and bottom and walls (including partition walls) on the sides. This outer circumferential space OR can be configured with an attic space in the upper part, double side walls in the side part, and a double floor space in the lower part.
If the rooms are consecutive, the adjacent room can also be used as a side space.

<Example of manufacturing equipment for pharmaceuticals, etc.>
Figure 3 shows an example of manufacturing equipment for pharmaceuticals, etc.
This example is a chatter-free facility A101 applied to a pharmaceutical manufacturing room.
This facility has a side wall 32 extending vertically from a floor slab 52 to an upper floor slab 53 to form a hermetically sealed compartment. Inside thereof, a floor 51, a ceiling 31, and an inner wall 37 are provided to form a pharmaceutical manufacturing room 3. A space is provided around the pharmaceutical manufacturing room 3 to form an insect-proof section 40.
In the insect-proof section 40, an upper insect-proof section 41 is formed using the attic, and a space is provided between the inner wall 37 and the side wall 32 to form a side insect-proof section 42. The insect-proof section 40 can be provided in one line, or it can be divided into individual sections, and furthermore, it can be divided into smaller sections.
The air conditioning system is configured so that the pharmaceutical manufacturing room 3 and the insect-proof compartment 40 can be controlled separately. The air conditioning system has a built-in insect control mode.

<Structure of the floor-wall (baseboard) section>
FIG. 4 shows an example of the structure of the floor-wall (baseboard) section regarding the connection between the floor and the wall. (a) is a view seen from the indoor side, and (b) shows a cross section.

On the floor surface, a base 55 is provided on the slab, and a coating film (layer) 56 such as urethane coating is formed on the base 55, so that no gaps occur.
The wall has a structure in which a gypsum board 39 is covered with a kerosene board 72, and a baseboard 59 is provided at the lower end. A blocking seal 61 is applied to the gap created at the lower end of the plasterboard 39. A blocking seal 62 is provided in the gap between the abutting portion of the Keical board 72 and the baseboard 59.
A coating film is applied continuously from the floor to the surface of the baseboard, so there are no gaps at the boundary between the wall and the floor. The continuous coating layer is continuous with the floor coating 56, the upright coating 57, and the baseboard coating 58. It is also possible to provide a coating film continuously on the upper end surface of the baseboard, and to provide a blocking seal 62 between this coating film and the lower end surface of the Keikaru board placed thereon.
Even if chatter beetles brought in on cardboard or the like fall onto the floor, there are no gaps on the floor or lower walls for the bugs to enter, and they will not live there.
In the illustrated example, a side insect-proof section 42 is provided, and the same structure is formed on the other wall and floor, so it is difficult for chatter beetles to enter the side insect-proof section 42. Therefore, even if they do get inside, they cannot get inside the manufacturing room.

<Structure of the floor-wall (extruded corner) section>
FIG. 5 shows an example of the protruding corner structure 7 provided with a shielding structure.
FIG. 5(a) shows the structure of the protruding corner. A wall material in which a calcical board 72 is laminated on the surface side of a gypsum board 71 is made to meet at right angles at the protruding corner. The tip of the other gypsum board 71b is in contact with the side surface of the tip of the gypsum board 71a. A double-structured L-shaped corner hardware 73 is provided at the gypsum board butt portion. Keical plates 72a and 72b are inserted between the corner hardware 73 from both sides.

At this projecting corner 7, the tip of the gypsum board 71b is taper-cut to create a triangular void, which is then filled with a blocking seal 63a. By forming the triangular gap, the sealing material can be firmly filled.
By inserting the Keical plate with the corner metal fitting 73 filled with sealing material, a blocking seal 63b is formed between the corner fitting 73 and the Keical plates 72a and 72b. The overflowing sealant also spreads between the Caical board and the gypsum board, forming a blocking seal 63b.
The gap at the protruding corner is blocked by the blocking seal 63 formed by two seals, the blocking seal 63a and the blocking seal 63b.

FIG. 5(b) shows a protruding corner seal 64 formed by a coating film formed at the lower part of the protruding corner. The protruding corner seal 64 is formed continuously with the floor coating 64a, the upright coating 64c, and the baseboard coating 64b.
Since the floor coating is continuously formed from both sides of the protruding corner and covers the surface of the corner hardware 73, no gap is created.
Due to this structure, there is no gap in the protruding corner 7 for chatter beetles to enter, and they cannot live there.

<Structure of floor-wall (inner corner) section>
FIG. 6 shows an example of the inside corner 8a.
FIG. 6(a) shows the construction state of the ceiling corner of the inside corner 8a formed by the ceiling 31 and the walls 37, 37 on both sides. Blocking seals 65a are provided on three sides of the ceiling corner.

FIG. 6(b) shows the structure of an inside corner 8b in which a gypsum board is stacked with a gypsum board and joined together at the corner. The tip of the other gypsum board 74b is in contact with the side surface of the tip of the gypsum board 74a. The tip of the gypsum board 74a is taper-cut to create a triangular gap at the abutting portion, and the gap is filled with a sealant to form a blocking seal 65b.
In contrast, the abutment of the Keical plates brings the tip of the Keical plate 77a into contact with the side surface of the tip of the Keical plate 77b. Make sure that the contact surfaces of the plasterboard are not continuous. A blocking seal 65a is applied to the corner where the Keical plates 77a and 77b abut.
The entrance corner 8 is shielded by a shielding seal 65 formed by a shielding seal 65b formed at the abutting part of the plasterboards 74a, 74b and a shielding seal 65a formed at the abutting part of the calcical boards 77a, 77b, thereby creating a gap through which chatter beetles can enter. There is no such thing, and it is not possible to live there.

<Structure of the floor-wall (R parting) section>
FIG. 7 shows an example of a shielding structure for an inside corner (a) and an outside corner (b) using a parting.
The inside corner is an example in which an aluminum R parting member 73a is used inside. The wall structure consists of gypsum board and Keikal board. A blocking seal 66b is provided at the butt corner of the plasterboard 74a and the plasterboard 74b. The calcical plates 75a and 75b on both sides are spaced apart from each other, and an R parting member 73a is interposed therebetween. A blocking seal 66a is provided between the R parting member 73a and the ends of the scalar plates 75a and 75b.
The cut-off seal 66 formed by these two cut-off seals 66a and 66b seals this corner, and there is no gap for chatter beetles to enter and cannot live there.

The protruding corner shown in FIG. 7(b) is an example using a chamfered cutout 74 made of aluminum. The wall structure consists of gypsum board and Keikal board. The gypsum board 76a and the gypsum board 76b are butted against each other so that a triangular space is formed. A blocking seal 67a is provided in the triangular gap. The ends of the Keikal boards 77a and 77b on both sides are installed lower than the ends of the gypsum board, so that the chamfered cutout 74 covers the triangular gap and the side of the cutout 74 comes into contact with the end of the Keikal board. It is located. Shutoff seals 67b, 67b are provided between the chamfered cutout 74 and the scalar plates 77a, 77b.
The cut-off seal 67 formed by the two cut-off seals 67a and 67b seals this protruding corner, and there is no gap for chatter beetles to enter, so that they cannot live there.

<Building example>
FIG. 8 shows an example of a building 8 in which the outer shell is a primary barrier against chatter beetles and the area around the insect-proof section is a secondary barrier. (a) is a cross-sectional perspective view of the building 8, and (b) is a partially enlarged view. The building 8 is an example of a simple building only surrounding the insect-proof section 13 (manufacturing room), and the size and number of floors are not limited to these.
The primary barrier 81 is formed by the outer shell 83 of the building 8 (outer wall 83a, roof slab 83b) and the 1F floor slab 83c. A joint seal 68 is applied to the joints of the members constituting the outer shell to seal them. For example, a joint seal 68a is applied between wall materials, and a joint seal 68d is applied between the 2F floor slab 84 and the outer wall 83a. Also, apply joint seals to gaps between openings such as windows and doors and the frame materials.

A secondary barrier 82 is formed by the insect-proof compartment wall 37 of the insect-proof compartment 13, the 1F floor slab 83c, and the 2F floor slab 84. The interlocking parts of the indoor walls of the insect-proof section 13 are constructed as illustrated in FIGS. 3 to 6.

The insect-proof section 13 (manufacturing room, etc.) is made into an independent space by providing the wall 37 of the insect-proof section between the upper and lower slabs. Provide an airtight structure where walls and floors meet. An outer wall-side insect-proof section 43 is provided between the wall 37 of the insect-proof section 13 and the outer wall 83a. A side insect-proof compartment 42 is provided between the insect-proof compartment 13 and the adjacent room 14. The upper part of the attic will be an insect-proof section 41.
An air conditioner 85a is placed on the upper floor, and an outdoor unit 85b is placed on the roof 83b, and a duct 86 communicates between the air conditioner 85a, the insect-proof section 13, and the like.

Note that the space between the primary barrier 81 and the secondary barrier 82 may be treated as the outer circumferential space of the insect-proof section 13. In this case, there is no need to make the outer wall-side insect-proof section 43, the side insect-proof section 42, and the upper insect-proof section 41 independent insect-proof sections.
If the entire building, which is a primary barrier, is treated as a peripheral pest control section and has a double structure with the insect control section 13, pest control can be performed independently for the insect control section 13 and the entire building. Even when a large space is divided into sections, it can be applied as separate sections.

The insect-proof compartment 13 and the peripheral insect-proof compartments 40 (outer wall-side insect-proof compartment 43, side insect-proof compartment 42, and upper insect-proof compartment 41) can be controlled as independently controllable air conditioning systems. The air conditioners can be installed individually or as a common air conditioner. Note that although one air conditioner is shown in FIG. 7A, it is only a schematic representation, and the number of air conditioners is not limited to one, and any number of air conditioners may be provided as required.

The indoor air conditioning system 120 can perform normal air conditioning for the insect-proof section 13 and the adjacent room 14 where work or office work is carried out, as well as air-conditioning for controlling insect pests. Pest control air conditioning at temperatures higher or lower than room temperature can be carried out during periods when normal operations are not carried out. In addition, by performing air conditioning under pest control conditions in the room temperature range, it is possible to maintain an indoor environment that repels chatate beetles. The air conditioning system incorporates chatate beetle control.
