Description

  The present invention relates to an ant-proofing tool used in an ant-proofing method for a basic heat-insulating structure in which a heat-insulating material is applied at a lower part of a building.

  The fabric foundation method and the solid foundation method are known for under-floor construction of buildings. In the fabric foundation method, an inverted T-shaped fabric foundation is formed along the outer periphery of the building, and moisture-proof concrete is placed on the inner side surrounded by the fabric foundation. In the solid foundation method, the foundation is formed as an integral reinforced concrete structure made of concrete placed on the ground beneath the fabric foundation.

  In recent highly airtight and highly heat-insulated buildings, it is often practiced to use an underfloor structure as a basic heat insulating structure. Specifically, in the case of the fabric foundation method, the indoor side near the joint (joint part) between the fabric foundation on the outer periphery of the building and the moisture-proof concrete, and in the case of the solid foundation method, the concrete base board on the ground and the rising foundation A heat insulating material is laid on the indoor side in the vicinity of the joint (joint part). In the following, “fabric foundation” in the fabric foundation method and “rise foundation” in the solid foundation method are collectively referred to as “foundation concrete standing part” or simply “standing part”, and “moisture-proof concrete” in the cloth foundation method. ”And“ concrete base board on the ground ”in the solid foundation method may be collectively referred to as“ basic concrete horizontal portion ”or simply“ horizontal portion ”.

  By the way, even if it is a concrete underfloor structure, a crack may arise in the joint part of a standing part and a horizontal part by a secular change, and there exists a possibility that a white ant may penetrate | invade indoors along this crack.

  Therefore, as a countermeasure against ant, it has been proposed to fill the indoor corner portion of the joint portion between the foundation concrete standing part and the foundation concrete lateral part with an ant-repellent agent (see, for example, Patent Document 1). According to this, it is possible to prevent entry into the indoor space by the above-mentioned ant-preventive agent.

  Further, in the invention of the above-mentioned Patent Document 1, the heat insulating material on the inner surface of the upright portion is positioned with a gap at the lower end, and the heat insulating material on the horizontal portion is slidably detachably inserted into the gap. The heat-insulating material is removed, and a new ant-preventing agent is added to the ant-preventing agent whose effectiveness has been reduced to maintain a permanent ant-repellent effect.

  As another conventional example, it is proposed to use a divided heat insulating material, to make the heat insulating material at the indoor side corner part detachable at the joint part of the standing part and the horizontal part, and to remove it appropriately to perform the ant-proofing treatment. (See, for example, Patent Document 2).

JP 2005-213837 A JP 2005-163489 A

  By the way, all of the conventional ant protection measures described above are intended to perform the construction work so that the worker faces the indoor side of the joint portion between the foundation concrete standing part and the foundation concrete horizontal part. Depending on the structure of the building, there are places where it is difficult to work. For example, in bathrooms and entrances, the space under the floor, that is, the gap between the floorboard and the foundation concrete horizontal portion is generally narrow, and it is difficult for the operator to sink. For this reason, it may be necessary to abandon the provision of the termite-proofing agent. However, even in such a place, it is possible to carry out the ant-proofing process when the work space remains during the construction work. However, when the effectiveness of the ant-proofing agent is reduced, additional processing of a new ant-proofing agent does not remain.

  Therefore, the present invention has been made paying attention to the above circumstances, and its purpose is to provide an ant-proofing treatment tool for use in an ant-proofing method that can be treated with an ant-proofing agent even if the space under the floor is narrow. Is to provide.

  Hereinafter, in order to facilitate the understanding of the present invention, reference numerals used in the drawings described below will be given as appropriate, but the present invention is not limited to the illustrated examples, and specific matters of the invention are limited by the reference numerals. Not a thing.

  The termite-proofing method according to the present invention (see FIGS. 1 and 2) includes a foundation concrete standing part (for example, a cloth foundation 13) formed along the outer peripheral part of a building, and a foundation concrete horizontal part connected thereto. (E.g., moisture-proof concrete 15), and a ant-proof construction method for a basic heat insulating structure in which heat insulating materials 16 and 14 are disposed in the vicinity of the standing portion on the upper surface 15a of the lateral portion and the inner side surface 13a of the standing portion. , A tunnel-shaped space 12 surrounded by the heat insulating materials 16 and 14 is formed along a corner portion (a portion of the corner 11) where the upper surface 15a of the lateral portion and the inner side surface 13a of the standing portion are joined. Then, a long ant-proofing treatment tool 30 is inserted from the side opening 12a in the tunnel-shaped space 12, and the space 12 is treated with an ant-proofing agent.

  Alternatively, the termite prevention method according to the present invention (see FIG. 8) includes a foundation concrete standing portion formed along the outer peripheral portion of the building, a foundation concrete horizontal portion connected thereto, and the standing portion. A partition portion 23 erected and connected to the erected portion inside the enclosed building, the vicinity of the erected portion on the upper surface 15a of the horizontal portion, and an inner surface 13a of the erected portion; In the termite prevention method for the basic heat insulating structure in which the heat insulating materials 16, 14, and 44 are disposed in the vicinity of the standing part on the side surface 23a of the partition part 23, the upper surface of the horizontal part and the standing part A tunnel-like space 12 surrounded by the heat insulating materials 16, 14, and 44 along a corner portion (a portion of the corner 11) where the inner side surface 13 a of the side wall 13 a and the side surface 23 a of the partition portion 23 that continues from the inner side surface 13 a are joined. In the partition 23 From the side of the opening 12a of the serial tunnel-shaped space 12, which comprises treating the said space 12 in termiticide by inserting the anti-termite treatment tool 30 long.

  As described above, in the present invention, since the ant-proofing treatment tool 30 is inserted from the side opening 12a of the tunnel-shaped space 12 and the ant-proofing agent is applied, the joining of the standing portion and the lateral portion of the basic concrete is performed. The worker is not positioned facing the indoor side of the place, and the ant-proofing process is performed from the side of the place to be processed. Therefore, even in places where the underfloor space is narrow, workers can place ant-preventive work in a relatively wide area on the side of the place, so that ant-proofing treatment can be performed reliably in any place in the building. Is possible.

  The “partition section” is a partition base part connected to the foundation concrete standing part formed on the outer peripheral part of the building, for example, generally referred to as “partition foundation”.

  Furthermore, in the ant protection method of the present invention (see FIGS. 1, 7, and 8), the ant protection processing tool 30 including the pipe 31 and the flexible hose 32 inserted into the pipe 31 is used, and the tunnel is used. The pipe 31 is inserted from the opening 12a on the side of the shaped space 12, and the straight portion (entrance straight space 12b) of the tunnel shaped space 12 is advanced. Subsequently, in the curved portion 12c of the tunnel shaped space 12, It is preferable to extend the flexible hose 32 from the tip opening of the pipe 31 and advance the flexible hose 32 deeper than the curved portion 12c (back space 12d).

  The ant protection device 30 can be inserted into the tunnel-shaped space 12 bent in this way, and the ant protection agent is taken out from the tip of the flexible hose 32 of the ant protection device 30 to form a tunnel shape. An ant-proofing treatment in the space 12 can be performed.

  As the ant-proofing treatment tool 30 according to the present invention (see FIG. 5), a pipe 31, a flexible hose 32 inserted into the pipe and extending / accommodating from the tip opening of the pipe 31, The thing provided with the ant-proofing agent presser connected to a flexible hose is mentioned.

  Further, as the ant protection tool 30, a pulley 33 having a space between the rotating wheel 35 and the hanging part 34 narrower than the tip of the pipe 31 is provided before the tip of the pipe 31, and the rotating wheel 35 and the hanging part 34 are provided. The flexible hose 32 is inserted between them, one end of the wire 36 is connected to the hanging part 34, and the other end of the wire 36 is extended toward the rear end of the pipe 31 (see FIG. 5). In the example, a wire 36 is inserted into a pipe 46 running in parallel with the pipe 31 through which the flexible hose 32 is inserted, and the other end of the wire 36 is extended from the rear end opening). It is preferable that the flexible hose 32 bends on the extending side of the hanging portion 34 when pulled in the rear end direction of the pipe.

  That is, by pulling the wire 36, the direction of the flexible hose insertion axis between the rotating wheel 35 and the hanging part 34 in the pulley 33 changes (specifically, bends toward the hanging part 34), and the flexibility is accordingly changed. The traveling direction of the hose 32 is bent. Therefore, even if the tunnel-shaped space 12 has a corner, the flexible hose 32 can be advanced from the corner. Moreover, since the rotating wheel 35 rotates, the flexible hose 32 can be smoothly advanced or retracted. As described above, since the space between the rotating wheel 35 and the suspended portion 34 of the pulley 33 is narrower than the tip of the pipe 31, the pulley 33 does not pass through the pipe 31 and go to the rear side.

  Further, as the above-mentioned ant protection processing tool 30, it is preferable that the pipe 31 is provided with an elastic tube 37 at its tip. That is, the tip of the pipe 31 is an elastic tube 37, and the pulley 33 is preferably located on the tip side of the elastic tube 37.

  If the tip of the pipe is rigid, when the wire 36 is pulled, the suspension part 34 of the pulley 33 cannot be attracted well, and the flexible hose is inserted between the rotating wheel 35 and the suspension part 34. It is difficult to change the axial direction. However, if the tip of the pipe 31 is an elastic tube 37, the flexible hose insertion axis direction can be smoothly changed when the wire 36 is pulled.

  Moreover, in the ant-proofing tool of this invention, it is preferable that the caster 38 was provided in the bending direction of the hose in the front-end | tip part of a flexible hose. In other words, it is preferable that the caster 38 is provided on the side of the flexible hose 32 on the same side as the side where the hanging part 34 is located with respect to the axial center of the pipe 31.

  As described above, by pulling the wire 36, the direction of travel of the flexible hose 32 is bent at the pulley 33, and the flexible hose 32 is extended from the opening of the end of the pipe 31 to bend the curved portion 12c of the tunnel-shaped space 12. At this time, the flexible hose 32 tends to advance in an arc along the bent radius. For this reason, the tip of the flexible hose 32 comes into contact with the side wall of the tunnel-shaped space 12, which may become a stopper and difficult to proceed.

  In this regard, if the caster 38 is provided as described above, the caster 38 comes into contact with the side wall of the tunnel-shaped space 12 first, and the caster 38 rotates smoothly to the back of the tunnel-shaped space 12. Can lead to. Further, the position of the tip of the flexible hose 32 can be stabilized in the tunnel-like space 12.

  The “tip portion” refers to the tip of the flexible hose 32 or the vicinity of the tip. That is, the caster 38 is not necessarily provided at the position of the tip of the flexible hose 32, and may be provided at a position slightly lower than the tip. Even if the flexible hose 32 draws an arc, it is sufficient that the caster 38 comes into contact with the side wall of the tunnel-shaped space 12 first. Therefore, as long as the size of the caster 38 is taken into consideration, the caster 38 is more than the tip of the flexible hose 32. It can be provided in a lowered position.

  According to the ant-proofing method according to the present invention, it is possible to treat a place where the underfloor space is narrow with an ant-proofing agent, and thus it is possible to reliably carry out the ant-proofing treatment at any place in the building. Moreover, the said ant-proof construction method can be performed favorably with the ant-proof processing tool concerning this invention.

<Embodiment 1>
In describing the ant protection method according to the first embodiment of the present invention, the following are described: 1: basic heat insulating structure under the building floor, 2: example of ant protection processing tool used in the ant protection method of the first embodiment, 3: The ant method will be described sequentially.

1. FIG. 1 is a schematic top view showing the entire underfloor structure of a building. FIG. 2 is a cross-sectional view showing the vicinity of the joint portion between the fabric foundation 13 (the foundation concrete standing portion) and the moisture-proof concrete 15 (the foundation concrete lateral portion), and is a cross section taken along the line AA and the line BB shown in FIG. It corresponds to a cross section.

  Embodiment 1 relates to a building by a cloth foundation method, and a concrete cloth foundation 13 is formed along the outer periphery of the building, and a moisture-proof concrete 15 is placed inside the cloth foundation 13. (FIGS. 1 and 2). Reinforcing bars are appropriately embedded in the fabric foundation 13 and the moisture-proof concrete 15.

  The heat insulating materials 14 and 16 are affixed to the inner surface 13a of the fabric foundation 13 and the vicinity of the fabric foundation 13 on the upper surface 15a of the moisture-proof concrete 15, but at this time, as shown in FIG. 13a and the upper surface 15a of the moisture-proof concrete 15 are joined at the corner 11 portion (in other words, the rising angle 11 portion of the inner surface 13a of the fabric foundation 13 from the upper surface 15a of the moisture-proof concrete 15). However, the corner 11 is covered with the heat insulating materials 14 and 16. Thereby, the space 12 is formed in a tunnel shape along the corner 11. In the first embodiment, the lateral width W of the space 12 is 45 mm and the height T is 25 mm. The size of the space 12 is not limited to this. Since the thickness of the heat insulating material is generally 10 to 200 mm, the space 12 is surrounded by the heat insulating material in consideration of the thickness of the heat insulating material to be used. It is good to set the size. Moreover, as shown in FIG. 1, about the upper surface 15a of the moisture-proof concrete 15, the heat insulating material 16 is affixed in the range to about 1 m inside from the cloth foundation 13, and is not affixed on the center part. In addition, about the sticking range of the heat insulating material 16, it is good to determine not only the example of illustration but considering the heat insulation effect and economical efficiency.

  As the heat insulating material, foamed resin such as foamed polyurethane, foamed polyethylene, and foamed polystyrene, glass wool, thick felt, fiber heat insulating material such as cotton made of synthetic fiber, porous material, a material filled with a particle heat insulating material, or These laminates and the like are used.

2. FIG. 5 is a diagram showing an example of the ant-proofing tool 30 used in Embodiment 1 of the present invention, and (a) and (b) are general views (however, excluding the ant-proofing agent presser). (C) is a figure showing the tip vicinity, (d) is a figure showing the hand side.

  The ant protection tool 30 includes a straight first pipe 31 having a flexible hose 32 inserted therein and a straight second pipe 46 having a wire 36 inserted therein in parallel. An anti-anticide presser (not shown) communicating with the flexible hose 32 is provided (FIG. 5A). The first and second pipes 31 and 46 are connected so as not to leave.

  The flexible hose 32 is made of, for example, a polyethylene-based synthetic resin and exhibits flexibility.

  The first pipe 31 is obtained by connecting a rubber elastic tube 37 to the tip of a pipe body 39. The pipe body 39 and the second pipe 46 are made of a metal such as aluminum or stainless steel, and are relatively hard.

  Each of the pipes 39 and 46 is divided into four parts, the front parts 39a and 46a are in the next parts 39b and 46b, and this is the next parts 39c and 46c, and further to the next parts 39d and 46d. It can be stored one after another, and the lengths of the pipes 39 and 46 can be expanded and contracted (FIG. 5 (b) is shown in FIG. A contracted state (for example, a length of 800 mm). In addition, this is extended and used appropriately according to the construction site.

  As shown in FIG. 5C, a pulley 33 is located on the distal end side of the first pipe 31 (specifically, the distal end side of the elastic tube 37), and a flexible hose 32 is inserted through the pulley 33. Specifically, the rotating shaft 35a of the rotating wheel 35 is located outside the inner space of the first pipe 31, and the hanging portion 34 is located at a position facing the axis of the first pipe 31 as a center. A gap between the rotating wheel 35 and the hanging part 34 is connected to the inner space of the first pipe 31. Then, the flexible hose 32 inserted into the first pipe 31 is subsequently inserted into the gap between the rotating wheel 35 and the suspension part 34. Further, the clearance between the rotating wheel 35 and the suspension portion 34 in the pulley 33 is smaller than the outer diameter of the first pipe 31, so that the pulley 33 does not go to the rear end side of the first pipe 31 and the tip of the first pipe 31. It is supposed to stay in the position.

  One end of the wire 36 is connected to the hanging part 34 of the pulley 33. The pulley 33 is not fixed to the elastic tube 37, the flexible hose 32, or the like, and is only connected to the wire 36 as a fixed portion.

  A caster 38 is attached to the side surface of the flexible hose 32 in the vicinity of the tip 32 a on the same side as the hanging portion 34.

  As shown in FIG. 5 (d), the other end of the wire 36 extends to the rear end (hand side) of the second pipe 46 and is connected to the handle 41. A flexible hose 32 extends from the rear end (hand side) of the first pipe 31 and is connected to an anti-anticide presser (not shown).

  Next, the operation of the ant protection tool 30 will be described.

  FIG. 6 is a view for explaining the operation of the ant protection device 30, and shows the vicinity of the tip of the ant protection device 30.

  The flexible hose 32 is extended from the distal end opening of the first pipe 31 (specifically, the distal end opening of the elastic tube 37) by a retraction operation from the proximal side into the first pipe 31, and by an operation of pulling out from the proximal side. It can be stored in the first pipe 31 (see FIG. 5).

  When the flexible hose 32 is retracted in a natural state, the insertion direction in the first pipe 31 and the insertion direction between the rotating wheel 35 and the suspension part 34 are substantially linear (θ = 180). °), the flexible hose 32 extends almost straight (FIG. 6A).

  On the other hand, when the wire 36 is pulled by the handle 41 (see FIG. 5) (arrow H shown in FIGS. 6B and 6C), the hanging portion 34 of the pulley 33 is pulled (arrow I). The elastic tube 37 bends so that the insertion axis direction between the rotating wheel 35 and the hanging part 34 is bent with respect to the axial direction of the first pipe 31 (θ <180 °). Thus, the traveling direction of the flexible hose 32 is bent (arrow J). The degree to which the traveling direction is bent is adjusted by adjusting the wire 36.

  FIG. 7 is a diagram illustrating a state in which the flexible hose 32 of the ant-proofing treatment tool 30 travels through a path bent at a right angle.

  When the traveling direction of the flexible hose 32 is bent in the curved portion of the passage as described above (FIGS. 7A and 7B), even if the bending angle is not the same right angle as the passage, The distal end of the flexible hose 32 abuts obliquely along the wall surface 13b and extends the flexible hose 32 so that the flexible hose 32 advances along the passage. At this time, since the rotating wheel 35 of the pulley 33 rotates, the flexible hose 32 is smoothly drawn out. The flexible hose 32 bent in the traveling direction at the pulley 33 tries to proceed in an arc as it is, but the caster 38 comes into contact with the inner wall surface 16b as shown in FIG. When the roll of the caster 38 rolls, the force in the inward direction is released and the progress along the passage is guided.

  In addition, from the front-end | tip opening 32a of the flexible hose 32, an ant preventive agent is jetted by the pressure of an ant preventive agent presser.

3. Method of preventing ant is described in the case of applying ant-proofing treatment to the upper left place in FIG. FIG. 3 is a perspective view of the vicinity of the joint portion between the fabric foundation 13 and the moisture-proof concrete 15 from above, and is an enlarged perspective view corresponding to the upper left portion in FIG.

  First, as shown in FIG. 1, the heat insulating materials 14a and 16a are removed from the surface of the cloth foundation 13 and the moisture-proof concrete 15 at a place that is relatively close to the above-mentioned ant-proofing treatment place and can secure a space where the worker can work ( Arrow C). Thereby, a lateral opening 12a in the tunnel-like space 12 appears. FIG. 4 is a perspective view of a place where the heat insulating materials 14 a and 16 a are removed, and shows the vicinity of the opening 12 a in the tunnel-like space 12.

  Then, the first and second pipes 31 and 46 of the ant protection device 30 are inserted into the tunnel-shaped space 12 through the opening 12a (arrow D shown in FIGS. 1, 3 and 4), and proceed through the entrance straight space 12b of the space 12. (Arrow E shown in FIG. 3).

  Subsequently, when reaching the curved portion 12c of the space 12, the wire 36 of the ant protection device 30 is pulled (arrow H shown in FIG. 6), and the traveling direction of the flexible hose 32 is bent (arrow F in FIG. 3, FIG. 6). (B), (c), FIG. 7 (a), (b)). Then, the flexible hose 32 is extended from the front end opening of the first pipe 31 (specifically, the front end opening of the elastic tube 37) (FIG. 7C), and is advanced from the bent portion 12c to the back (back space 12d) (FIG. 7). 3 arrow G). At this time, the caster 38 comes into contact with the heat insulating material wall surface 16b which is a wall (inner wall) in the bending direction, and the roll of the caster 38 rolls to guide the progress to the back (arrow G direction).

  In this way, the tip 32a of the flexible hose 32 reaches the end of the ant-proof treatment place, and then the flexible hose 32 is gradually brought to the near side while the ant-proofing agent is ejected from the opening of the tip of the flexible hose 32. Pull out. When the curved portion 12c of the tunnel-like space 12 is reached, the flexible hose 32 is gradually pulled out together with the first and second pipes 31 and 46 while spraying the termite-proofing agent in the same manner. In this way, the entire inner space 12d, the curved portion 12c, and the entrance straight space 12b of the tunnel-shaped space 12 are treated with the termite-proofing agent.

  Thereafter, the heat insulating materials 14a and 14b removed first are returned to their original positions, and the ant-proofing work is completed.

  In a place where the space between the floor and the moisture-proof concrete 15 is narrow, such as in a bathroom or entrance, the worker cannot reach. However, in the first embodiment, the worker is positioned facing the ant-proofing portion. Without being able to operate from a relatively wide place away from it. Since the ant-proofing treatment can be carried out even in such a narrow space under the floor, it is possible to reliably carry out the ant-proofing treatment at any place in the building.

  The tunnel-like space 12 can also be used for inspections such as inserting a small camera into the space 12 and confirming the invasion status of white ants.

  In addition, as a termite preventer, a liquid thing is preferable. In the case of a powdery or granular ant-proofing agent, there are cases where powder or granules remain in the space 12 even after the ant-proofing effect is lost and the tunnel-like space 12 is blocked. For this reason, there is a concern that the pipe 31 and the flexible hose 32 cannot be inserted even if the ant protection processing tool 30 is used again to perform the ant protection processing as described above. In this regard, since the liquid space ant preventive agent does not block the tunnel-shaped space 12, the ant repellent treatment can be performed many times. As a method for applying the liquid ant-preventing agent to the tunnel-shaped space 12, it may be sprayed in the form of foam or sprayed in the form of mist or water droplets.

<Embodiment 2>
In describing the termite-proofing method according to the second embodiment of the present invention, the following will sequentially describe a 1: basic heat insulating structure under a building floor and 2: a termite-proofing method. The ant protection tool used in the second embodiment is the same as that in the first embodiment.

1. FIG. 8 is a diagram for explaining an ant protection method according to Embodiment 2 of the present invention, (a) is a schematic top view showing the entire underfloor structure of a building, and (b). These are the enlarged views of the lower right part in (a). In addition, the part which attached | subjected the code | symbol same as FIGS. 1-4 is the same component as the example of FIGS.

  Embodiment 2 is also about the building by a cloth foundation construction method, and while the cloth foundation 13 is formed along the outer peripheral part of a building, a partition part (partition foundation) in the part by which the wall in a building is arrange | positioned. 23 is formed. The partition 23 is erected so as to be connected to the outer fabric base 13. A moisture-proof concrete 15 is placed on the entire inner surface surrounded by the outer fabric foundation 13.

  A heat insulating material 14 is affixed to the inner side surface 13a of the outer fabric base 13, and a heat insulating material 16 is affixed to the upper surface 15a of the moisture-proof concrete 15 within a range of about 1 m from the cloth base 13 to the inside. In addition, a heat insulating material 44 is attached to the side surface 23a of the partition portion 23 so as to be connected to the heat insulating material 14 within a range of about 1 m from the cloth base 13 to the inside. However, the joint angle portion (corner 11 portion) between the inner side surface 13a of the outer fabric base 13 and the upper surface 15a of the moisture-proof concrete 15, and the joint angle portion between the side surface 23a of the partition 23 and the upper surface 15a of the moisture-proof concrete 15 ( A space 12 is left in the corner 11), and heat insulating materials 14, 44, and 16 are disposed so as to cover the corner 11 (see FIG. 2). Thus, the space 12 is formed in a tunnel shape along the joint angle portion between the fabric foundation inner side surface 13a and the moisture-proof concrete upper surface 15a and the joint angle portion between the partitioning portion side surface 23a and the moisture-proof concrete upper surface 15a. FIG. 8). The space 12 in the second embodiment has a width W of 45 mm and a height T of 25 mm.

  A cover (not shown) made of a heat insulating material is attached to the opening 12a of the tunnel-shaped space 12 opened below the side edge of the heat-insulating material 44 attached to the partitioning portion side surface 23a. Is blocked. In addition, improvement in heat insulation and dew proofing can be expected by covering.

2. Method for preventing ants In the second embodiment, operation is performed from the opening 12a below the side end of the heat insulating material 44 on the partitioning portion side surface 23a.

  First, the lid attached to the opening 12a is removed. The state near the end of the heat insulating material 44 when the lid is removed is the same as that in FIG. 4 used in the description of the first embodiment.

  Then, as in the first embodiment, the first and second pipes 31 and 46 of the ant protection device 30 are inserted from the opening 12a of the tunnel-shaped space 12 (arrow D shown in FIGS. 4 and 8), and proceed through the inlet straight space 12b. Insert (FIG. 8B). Subsequently, when the curved portion 12c of the space 12 is reached, the wire 36 of the ant-proofing treatment tool 30 is pulled (arrow H in FIG. 6), and the traveling direction of the flexible hose 32 is bent (FIGS. 6B and 6C). ), FIG. 7 (a), (b)), and then the flexible hose 32 is extended from the opening of the tip of the first pipe 31 (FIG. 7 (c)) and advanced into the inner space 12d (FIG. 8 (b)). ), The tip 32a of the flexible hose 32 is made to reach the end 12e of the ant protection processing place.

  Next, while blowing out the termite-proofing agent from the front end opening of the flexible hose 32, the flexible hose 32 is gradually pulled out to the hand side and reaches the curved portion 12c of the tunnel-shaped space 12, and then the ant-proofing is similarly performed. The flexible hose 32 is gradually pulled out to the hand side together with the first and second pipes 31 and 46 while jetting the agent. In this way, the termite-proofing agent is applied to the entire inner space 12d, the curved portion 12c, and the entrance straight space 12b of the tunnel-shaped space 12.

  Next, the lid made of the heat insulating material is attached to the opening 12a again. Thus, the ant-proofing work is completed.

  Also in the second embodiment, since the worker does not need to face the ant-proofing part in the ant-proofing work, the ant-proofing is performed even in a place where the space under the floor (between the floor and the moisture-proof concrete 15) is narrow. Processing can be performed.

<Other embodiments>
Although the above-described Embodiments 1 and 2 have shown the case of the insulated underfloor structure of the fabric foundation method, the same can be applied to the insulated underfloor structure of the solid foundation method.

  In the first and second embodiments, the case where the ant protection method of the present invention is applied to the entire building has been shown. However, the present invention is applied only to a part of the building, for example, a narrow space under the floor such as a bathroom or an entrance. You may make it employ | adopt the ant-proof construction method of invention.

  In the above-mentioned example, the pipe 31 and 46 has a configuration in which the pipes 31 and 46 can be expanded and contracted as the ant protection processing tool, but may have a structure that does not expand and contract. As the length of the pipe 31, it is preferable to use one according to the processing place. Moreover, although the thing of the structure which penetrated the wire 36 to the 2nd pipe 46 was shown, the wire 36 may be exposed. Alternatively, the wire 36 may be inserted through the first pipe 31 through the flexible hose 32.

  In the ant-proofing treatment tool 30 in the above example, the elastic tube 37 at the tip of the first pipe is made of rubber, but is not limited thereto, and may be a coil spring, for example. In the case of a coil spring, the flexible hose 32 may be inserted through the central space.

  As mentioned above, the present invention has been described more specifically with examples. However, the present invention is not limited by the above examples, and may be implemented with appropriate modifications within a range that can be adapted to the above purpose. Of course, they are all possible and are included in the technical scope of the present invention.
