Description

  The present invention relates to an ant protection system, and more particularly to an ant protection system for preventing, for example, an invasion of white ants from a pipe penetration portion of a concrete foundation of a building.

  An example of a conventional ant protection system is disclosed in Patent Document 1.

In this ant protection system of Patent Document 1, a sheath pipe and a pipe inserted into the sheath pipe penetrate the concrete foundation of the building, and a plate-like butyl rubber is provided on the outer peripheral surface of the indoor side end of the sheath pipe. An ant protection tape (outer ant protection member) to which an ant protection agent is added is provided as an ant protection treatment. The termite-proof tape is embedded in the concrete foundation and prevents termites from entering between the outer surface of the sheath tube and the concrete foundation. Moreover, between the inner surface of the edge part of the outdoor side of a sheath pipe, and the outer surface of piping, the ant-proof packing (inner ant member) which added the ant-proofing agent to the synthetic rubber as an ant-proofing process is provided.

JP2011-26945A [E03C 5/02]

  In general, the effect of the termite-proofing agent can be sustained only for about 5 years, and reprocessing of the termite-proofing agent has to be performed with the aim of 5 years. Even if the ant-proof effect is achieved, since the ant-proof tape is embedded in the concrete foundation, it cannot be renewed without damaging the concrete foundation. Therefore, with the technique of Patent Document 1, it is difficult to update the termite-proofing agent. In addition, when a gap is generated between the concrete foundation and the outer surface of the sheath pipe due to shrinkage of the concrete due to temperature change or an earthquake, the ant-proof tape cannot properly exhibit the ant-proof effect. Then, since the state of the ant-proof tape cannot be visually confirmed after the concrete foundation is formed, there was anxiety about whether or not the ant-proof tape can maintain the ant-proof effect.

  Therefore, the main object of the present invention is to provide a novel ant protection system.

  Another object of the present invention is to provide an ant protection system that can maintain a reliable ant protection effect and can be updated in the future.

However, the double pipe 102 described below is merely an example, and can be changed as appropriate without departing from the scope of the present invention.

  As shown in FIGS. 1 and 2, the sheath tube 104 is made of a synthetic resin such as polyethylene, and is combined with a first sheath tube portion 108 and a second sheath tube portion 110 that are formed as separate bodies. It is formed in a letter shape. The first sheath tube portion 108 extends in a vertical or substantially vertical direction, and an upper end thereof opens on the indoor side of the concrete foundation 100. The upper end of the first sheath tube portion 108 has an enlarged diameter receiving port shape, and a joint tube 128 described later is connected to the receiving port (indoor side receiving port) 112. Moreover, the connection part 114 which protrudes in a short cylinder shape toward a horizontal direction is formed in the lower end part of the 1st sheath tube part 108. As shown in FIG. For example, a thread groove is formed on the inner surface of the connection portion 114.

  The second sheath tube portion 110 extends horizontally or substantially horizontally from the opening 114 of the first sheath tube portion 108. For example, a thread is formed on the outer surface of one end of the second sheath tube part 110, and this thread is screwed into the thread groove of the connection part 114. The other end of the second sheath tube part 110 has an enlarged diameter receiving shape, and the receiving port (outdoor side receiving port) 116 opens on the outdoor side of the concrete foundation 100.

  On the other hand, the inner tube 106 is made of a synthetic resin such as vinyl chloride, and is combined with a bent inner tube portion 118, a first inner tube portion 120, and a second inner tube portion 122, which are formed as separate bodies. It is formed in a shape. The bent inner tube portion 118 is, for example, a 90 ° elbow, and is disposed inside the first sheath tube portion 108. A first receiving port 124 that opens in the vertical upward direction is formed at one end of the bent inner tube portion 118, and a second receiving port 126 that opens in the horizontal direction is formed at the other end.

  Furthermore, a first inner tube portion 120 extending vertically upward is disposed in the first sheath tube portion 108. The first inner tube portion 120 is a vinyl chloride tube or the like, and one end of the first inner tube portion 120 is inserted into the first receiving port 124 of the bent inner tube portion 118 and bonded and bonded with, for example, an adhesive. The other end of the first inner pipe part 120 extends indoors from the first sheath pipe part 108 and is connected to an indoor drain pipe (not shown) via a joint or a junction.

  A second inner tube portion 122 extending in the horizontal direction is disposed in the second sheath tube portion 110. The second inner pipe portion 122 is a vinyl chloride pipe or the like, and one end of the second inner pipe portion 122 is inserted into the second receiving port 126 of the bent inner pipe portion 118 and is joined to a rubber ring in a watertight state, for example. The other end of the second inner pipe part 122 extends from the second sheath pipe part 110 to the outside and is connected to an outdoor drain pipe (not shown) via a joint or the like.

  Such a double pipe 102 is arranged in a foundation mold (not shown) for making the concrete foundation 100 and is embedded in the concrete foundation 100 at the time of construction on the concrete foundation 100 of the building.

  Specifically, first, the inner tube 106 is inserted into the sheath tube 104. However, the inner pipe 106 may be inserted into the sheath pipe 104 after the concrete foundation 100 is placed. Then, the indoor side receiving port 112 of the sheath pipe 104 opens slightly below the horizontal surface (upper surface) 100a on the indoor side of the concrete foundation 100, and the outdoor side receiving port 116 of the sheath pipe 104 is exposed and opened to the outdoors. In addition, the sheath tube 104 is fixed by suspending the sheath tube 104 on the reinforcing bar in the basic form frame with a support or the like.

  However, the horizontal surface 100a of the concrete foundation 100 means a surface that extends in the horizontal direction on the indoor side in the concrete foundation 100, and "horizontal" does not define whether or not it exactly coincides with the horizontal. .

  And the joint pipe 128 is inserted in the indoor side receiving port 112 of the sheath pipe 104, concrete is laid in a foundation formwork, and the concrete foundation 100 is formed. The joint pipe 128 is a straight pipe formed of a synthetic resin such as vinyl chloride, and the outer diameter thereof is set to be equal to the diameter of the indoor side receiving port 112 of the sheath pipe 104. Subsequently, when the concrete is dried, the joint pipe 128 exposed above the horizontal surface 100a of the concrete foundation 100 is cut as necessary, and the operation is finished.

  The double pipe 102 to be constructed on the concrete foundation 100 of the building has been described above.

  In the following, examples and embodiments of the present invention will be described on the premise of such a double pipe 102, using them as necessary.

  As shown in FIG. 3 and FIG. 4, the ant protection system 10 prevents the invasion of white ants from the pipe penetration portion of the concrete foundation 100 on which the double pipe 102 as described above is constructed. A receiving plate 12 provided around the pipe 106 (here, the first inner pipe section 120) is provided.

  The backing plate 12 is made of a synthetic resin such as polyethylene, is formed in a donut plate shape having an opening 14 in the center, is externally fitted to the inner pipe 106 exposed above the horizontal surface 100a of the concrete foundation 100, and is also a concrete foundation. 100 horizontal surfaces 100a and the upper end of the joint pipe 128 are disposed. That is, the inner tube 106 is inserted into the opening 14 of the receiving plate 12, and the inner diameter of the receiving plate 12 (that is, the diameter of the opening 14) is set to be approximately equal to the outer diameter of the inner tube 106. Specifically, the inner diameter of the receiving plate 12 is such that the gap between the inner peripheral edge of the receiving plate 12 and the outer surface of the inner tube 106 is at most 1 mm, for example, 89.5 mm. Further, the outer diameter of the receiving plate 12 is set to be larger than the diameter of the indoor side receiving port 112 of the sheath tube 104, and is, for example, 246 mm.

  An outer periphery defining portion 16 is provided outside the receiving plate 12. The outer periphery defining portion 16 defines the outer periphery of a pea intrusion preventing agent 28 described later, is formed in a substantially short cylindrical shape by a synthetic resin such as polyethylene, and is fixed on the horizontal surface of the concrete foundation 100. As shown in FIG. 5, the outer periphery defining portion 16 has a short cylindrical portion 18. The short cylindrical portion 18 is formed in a short cylindrical shape extending in the vertical direction, and a donut plate-shaped support portion 20 protruding outward from the outer surface of the short cylindrical portion 18 is formed at the lower end thereof. The support portion 20 includes a plurality of, for example, four protrusions 22 in this embodiment, which are arranged at intervals in the circumferential direction. Bolt holes 24 penetrating in the thickness direction are formed in the protrusions 22. Then, as shown in FIGS. 3 and 4, the outer periphery defining portion 16 is fixed on the horizontal plane 100 a of the concrete foundation 100 by driving a bolt 26 inserted into the bolt hole 24 of the protrusion 22 into the horizontal plane 100 a of the concrete foundation 100. To do.

  Also, white ant penetration preventing agent 28 is accumulated above and around the receiving plate 12. The white ant intrusion preventing agent 28 is made of colemanite or glass in the form of particles or small pieces, and the particles themselves or the small pieces themselves have ant-proofing performance. That is, the white ant intrusion preventing agent 28 physically prevents the invasion of the white ants, and prevents the white ants from passing through the inside of the accumulated white ant intrusion preventing agent 28 or along the periphery. For this reason, compared with the case where the invasion of white ants is prevented by using an ant-proofing agent or the like, periodic reprocessing is unnecessary, and the burden on the environment and people can be reduced. For example, in this embodiment, a pointed glass piece is used as the white ant intrusion preventing agent 28. Specifically, a non-chemidan crystal (trade name) manufactured by Fukubi Chemical Industry Co., Ltd. can be used. . However, as the white ant intrusion preventing agent 28, inorganic particles impregnated with an ant preventive chemical can be used.

  As described above, the outer periphery of the white ant penetration preventing agent 28 is defined by the outer periphery defining unit 16. That is, the white ant penetration preventing agent 28 is accumulated (filled) in a container-like space having an upper opening surrounded by the inner surface of the short cylindrical portion 18 of the outer periphery defining portion 16, the outer surface of the inner tube 106, and the horizontal surface 100 a of the concrete foundation 100. And has a ring shape as a whole. As shown in FIGS. 3 and 6, the maximum height at which the white ant penetration preventing agent 28 can be accumulated is defined according to the length (height) of the short cylindrical portion 18 in the vertical direction. The maximum range in which 28 can be accumulated is defined according to the inner diameter of the short cylindrical portion 18.

  Here, according to the experiment by the inventors of the present application, when the white ant intrusion preventing agent 28 of this embodiment is accumulated, the white ants are inside the accumulated white ant intrusion preventing agent 28 or the periphery of the white ant intrusion preventing agent 28. It was confirmed that it was not possible to travel 10 mm or more along the route along

  That is, in order to prevent the white ants from passing through the inside of the white ant intrusion preventing agent 28 and the path along the periphery in the vertical direction, it is necessary that the white ant intrusion preventing agent 28 has a height of at least 10 mm. Yes, preferably 20 mm or more, more preferably 30 mm or more. Therefore, in this embodiment, the height d1 of the short cylindrical portion 18 of the outer periphery defining portion 16 is set to 30 mm, and the white ant penetration preventing agent 28 is integrated to a height of 30 mm according to the height d1 of the short cylindrical portion 18. Like to do.

  Similarly, in order to prevent the white ants from passing in the horizontal (lateral) direction along the path along the periphery or the periphery of the white ant intrusion preventing agent 28, the white ant intrusion preventing agent 28 is 10 mm or more in the horizontal direction. It is necessary to have a length (horizontal distance), preferably 20 mm or more, and more preferably 30 mm or more. Therefore, in this embodiment, the inner diameter of the short cylindrical portion 18 of the outer periphery defining portion 16 is set to 317 mm so that the horizontal distance d2 between the inner surface of the short cylindrical portion 18 and the outer peripheral edge of the receiving plate 12 is about 36 mm. (∵ (317-246) ÷ 2 = 35.5 mm). By doing so, the white ant penetration preventing agent 28 is accumulated in a range where the horizontal distance from the outer peripheral edge of the receiving plate 12 is 30 mm.

  Referring to FIG. 1, in order to construct such an ant protection system 10 in a pipe penetration portion of a concrete foundation 100, first, the joint pipe 128 exposed above the horizontal surface 100 a of the concrete foundation 100 is cut and joined. The upper end of the pipe 128 is flush with the horizontal surface 100 a of the concrete foundation 100.

  Then, the receiving plate 12 is externally fitted to the inner pipe 106 (here, the first inner pipe portion 120) exposed above the horizontal plane 100a of the concrete foundation 100, and the receiving plate 12 is connected to the horizontal plane 100a of the concrete foundation 100 and the joint pipe. Place on top of 128.

  And the outer periphery prescription | regulation part 16 is arrange | positioned in the position which ensured the predetermined distance from the outer periphery of the receiving plate 12, and the outer periphery prescription | regulation part 16 is fixed on the horizontal surface 100a of the concrete foundation 100 with the volt | bolt 26. Then, the white ants intrusion inhibitor 28 is accumulated in a ring shape as a whole in a container-like space of the upper opening surrounded by the inner surface of the short cylindrical portion 18, the outer surface of the inner tube 106, and the horizontal surface of the concrete foundation 100, A special solidifying agent is sprayed on the surface of the white ant intrusion preventing agent 28 so as to prevent the accumulated white ant intrusion preventing agent 28 from moving (scattering) beyond the outer periphery defining portion 16 to the outside. For example, an adhesive such as a special resin emulsion system can be used as the solidifying agent. Thereby, construction of the ant-proof system 10 to the piping penetration part of the concrete foundation 100 is completed.

  In this way, by installing the ant protection system 10 on the pipe penetration portion of the concrete foundation 100, as shown in FIG. 7 (a), the white ants are outside the sheath pipe 104 from the outside (the sheath pipe 104 and the concrete foundation 100). , The white ants that have reached the outer surface of the sheath pipe 104 and the joint pipe 128 and reached between the receiving plate 12 and the horizontal surface 100a of the concrete foundation 100 are inserted into the receiving plate 12. When the white ant intrusion prevention agent 28 accumulates at a predetermined height at which the white ant intrusion prevention agent 28 can exert its ant-preventing performance even when trying to advance inside the white ant intrusion prevention agent 28 upward from the outer peripheral edge of the white ant Since the white ants cannot pass through the inside of the white ant intrusion preventing agent 28 upward, the white ants can be prevented from entering the room.

  In addition, as shown in FIG. 7 (b), the white ants that have reached between the receiving plate 12 and the horizontal surface 100 a of the concrete foundation 100 in the same way are introduced into the white ants from the outer peripheral edge of the receiving plate 12 outward. Even when trying to advance the path along the bottom of 28 (that is, the gap between the bottom of the white ant intrusion preventing agent 28 and the horizontal surface 100a of the concrete foundation 100), the white ant intrusion preventing agent 28 prevents the ant invasion performance from the outer peripheral edge of the backing plate 12. Since the white ants do not pass through the path along the bottom of the white ant intrusion prevention agent 28 because the white ant intrusion prevention agent 28 is accumulated in a predetermined distance range in which Can prevent the entry of white ants.

  Further, as shown in FIG. 7C, when the white ants enter the pipe penetration portion from the outside through the outside of the inner pipe 106 (the gap between the sheath pipe 104 and the inner pipe 106), The white ants that have reached the space between the inner pipe 106 and the inner peripheral edge of the receiving plate 12 on the outer surface travel along the inner peripheral edge of the white ant intrusion preventing agent 28 (that is, the inner peripheral edge of the white ant intrusion preventing agent 28). When the white ant intrusion prevention agent 28 is accumulated at a predetermined height at which the ant intrusion prevention agent 28 can exhibit the ant prevention performance, even when trying to move upward the gap between the ant and the outer surface of the inner pipe 106, Since the white ants cannot pass the path along the inner peripheral edge of the white ant intrusion preventing agent 28 upward, the white ants can be prevented from entering the room.

  As described above, the double pipe 102 such as the gap between the sheath pipe 104 and the concrete foundation 100 and the gap between the sheath pipe 104 and the inner pipe 106 is constructed by installing the ant protection system 10 in the pipe penetration portion of the concrete foundation 100. It is possible to prevent the white ants that have entered the pipe penetration part from entering the indoor.

  Here, the white ant intrusion preventing agent 28 physically prevents the invasion of white ants, so that as described above, periodic reprocessing is unnecessary, but if the accumulated white ant intrusion preventing agent 28 collapses and moves, The white ant intrusion preventing agent 28 cannot exert its ant preventing performance. However, in this ant protection system 10, the outer periphery of the accumulated white ant intrusion preventing agent 28 is defined by the outer periphery defining portion 16, so that the shape of the accumulated white ant intrusion preventing agent 28 is fixedly held. The white ant intrusion preventing agent 28 can be prevented from collapsing and moving. Therefore, according to this embodiment, it is possible to maintain a reliable ant protection effect.

  Moreover, in this ant protection system 10, the white ant intrusion preventing agent 28 is exposed on the horizontal surface 100 a of the concrete foundation 100, so that the accumulated white ant intrusion preventing agent 28 collapses even when an earthquake or ground subsidence occurs. It is possible to easily visually check whether it has moved. And even if the white ant intrusion preventing agent 28 is broken and moved, the white ant intrusion preventing agent 28 can be renewed (or repaired) by simply replacing or rearranging the white ant intrusion preventing agent 28. It can be performed.

  That is, according to this embodiment, it is possible to visually check the white ant intrusion preventing agent 28 even after the ant protection system 10 is installed, so that the white ant intrusion preventing agent 28 can be easily updated.

  In this embodiment, the joint pipe 128 is connected to the indoor receiving port 112 of the sheath pipe 104, and the receiving plate 12 is disposed on the upper end of the joint pipe 128 and the horizontal surface 100a of the concrete foundation 100. It is not necessary to be limited to this, and it is sufficient if the receiving plate 12 is provided in the vicinity of the tube end of the sheath tube 104. As shown in FIG. 8, the sheath pipe 104 is arranged so that the indoor side receiving port 112 of the sheath pipe 104 is exposed and opened on the horizontal surface 100 a of the concrete foundation 100, and the pipe end (that is, the indoor side receiving port 112 of the indoor side receiving port 112 is opened). The backing plate 12 may be disposed on the end surface) and the horizontal surface 100 a of the concrete foundation 100. In this case, after arranging the sheath pipe 104, the indoor side receiving port 112 exposed above the horizontal surface 100a of the concrete foundation 100 of the sheath pipe 104 is cut as necessary, and the pipe end of the sheath pipe 104 is made concrete. It should be flush with the horizontal surface 100a of the foundation 100.

  Further, in this embodiment, the receiving plate 12 and the outer periphery restricting portion 16 are provided separately, but it is not necessary to be limited to this.

  For example, an ant protection system 10 according to another embodiment of the present invention shown in FIG. 9 includes a white ant intrusion inhibitor accumulation unit 30 disposed on a horizontal surface 100 a of a concrete foundation 100. Hereinafter, the ant protection system 10 shown in FIG. 9 will be described in detail, but the same reference numerals are used for the same parts as the ant protection system 10 shown in FIG. 1, and the description thereof is omitted or simplified.

  As shown in FIG. 9 and FIG. 10, the peanut penetration preventing agent integrated unit 30 is made of a synthetic resin such as polyethylene, and includes a receiving plate 12 and an outer periphery regulating portion 16. The receiving plate 12 is formed in a donut plate shape having an opening 14 in the center, and is fitted on the inner pipe 106 exposed above the horizontal plane 100a of the concrete foundation 100, and also the horizontal plane 100a and the joint pipe 128 of the concrete foundation 100. Is disposed on the upper end of the. A rising portion 32 that rises in the vertical direction over the entire length in the circumferential direction is formed on the outer peripheral edge of the backing plate 12. A plurality of, for example, four connecting portions 34 are formed at the upper end of the rising portion 32 at intervals in the circumferential direction. The connecting portion 34 is formed in a rectangular plate shape, extends outward and upward from the upper end of the rising portion 32, and connects the rising portion 32 and the outer periphery regulating portion 16.

  The outer periphery restricting portion 16 has a short cylindrical portion 18 and a protrusion 36. The short cylindrical portion 18 is formed in a short cylindrical shape extending in the up-down direction, and a plurality of, for example, four protrusions 36 arranged at intervals in the circumferential direction are formed at the lower end thereof. The protrusion 36 protrudes outward from the outer surface of the short cylindrical portion 18, and a bolt hole 38 for inserting the bolt 40 is formed in the protrusion 36. Then, the bolt 40 inserted through the bolt hole 38 of the protrusion 36 is driven into the horizontal surface 100 a of the concrete foundation 100, thereby fixing the white ant intrusion preventing agent accumulation unit 30 on the horizontal surface 100 a of the concrete foundation 100.

  Further, a white ant penetration preventing agent 28 is accumulated above and around the receiving plate 12. The white ant intrusion preventing agent 28 is, for example, a pointed glass piece, and is an upper opening container surrounded by the inner surface of the short cylindrical portion 18 of the outer periphery defining portion 16, the outer surface of the inner tube 106, and the horizontal surface 100 a of the concrete foundation 100. It is accumulated (filled) so as to have a ring shape as a whole.

  The outer periphery of the white ant intrusion preventing agent 28 is defined by the outer periphery defining portion 16, and the maximum height at which the white ant intrusion preventing agent 28 can be accumulated is defined according to the height of the short cylindrical portion 18, as in the embodiment of FIG. The maximum range in which the white ant penetration preventing agent 28 can be accumulated is defined according to the inner diameter of the short cylindrical portion 18.

  That is, as shown in FIGS. 9 and 11, the vertical length (height) d <b> 3 of the short cylindrical portion 18 is such that the white ants pass through the path along the inside and the periphery of the white ant intrusion preventing agent 28 in the vertical direction. In order to prevent this, for example, it is set to 30 mm, and the white ant penetration preventing agent 28 is accumulated to a height of 30 mm in accordance with the height d3 of the short cylindrical portion 18.

  In addition, the distance between the rising portion 32 and the short cylindrical portion 18 (that is, the receiving plate 12 of the receiving plate 12) so that the white ants can be prevented from passing in the horizontal direction along the path inside the white ant intrusion preventing agent 28 or along the periphery. The distance d4 between the outer peripheral edge and the outer peripheral restricting portion 16 is set to, for example, 30 mm, so that the white ant intrusion preventing agent 28 is accumulated within the horizontal distance of 30 mm from the outer peripheral edge of the receiving plate 12. I have to.

  Referring to FIG. 9, in order to construct such an ant protection system 10 in the pipe penetration portion of the concrete foundation 100, the receiving plate 12 is fitted on the inner pipe 106 exposed above the horizontal surface 100 a of the concrete foundation 100. Then, the white ant intrusion preventing agent accumulation unit 30 is arranged on the horizontal surface 100a of the concrete foundation 100 and the upper end of the joint pipe 128 as they are.

  Then, the white ant intrusion inhibitor accumulation unit 30 is fixed on the horizontal surface 100 a of the concrete foundation 100 by the bolt 40 inserted into the bolt hole 38 of the protrusion 36. Then, the white ant intrusion preventing agent 28 is accumulated in the entire ring-shaped space surrounded by the short cylindrical portion 18, the inner pipe 106 and the horizontal surface of the concrete foundation 100, and a dedicated surface is provided on the surface of the accumulated white ant intrusion preventing agent 28. Solidify by spraying solidifying agent. Thereby, construction of the ant-proof system 10 to the piping penetration part of the concrete foundation 100 is completed.

  As shown in FIG. 12 (a), the white ants entered the pipe penetration part from the outside through the outside of the sheath pipe 104 as shown in FIG. 12 (a) by constructing the ant protection system 10 in the pipe penetration part of the concrete foundation 100. Sometimes, the white ants that have reached between the receiving plate 12 and the horizontal surface 100a of the concrete foundation 100 try to advance inside the white ant intrusion preventing agent 28 from the outer peripheral edge of the receiving plate 12 upward. Since the white ant intrusion prevention agent 28 is accumulated at a predetermined height at which the white ant can exert its ant prevention performance, the white ant cannot pass through the inside of the white ant intrusion prevention agent 28 upward. Can be prevented from entering.

  In addition, as shown in FIG. 12 (b), the white ants that have reached between the receiving plate 12 and the horizontal surface 100 a of the concrete foundation 100 in the same way are introduced into the white ants from the outer peripheral edge of the receiving plate 12 toward the outside. Even if it is going to go along the path along the bottom of 28, the white ant intrusion prevention agent 28 is accumulated within a predetermined distance from the outer peripheral edge of the backing plate 12 so that the white ant intrusion prevention agent 28 can exhibit the ant prevention performance. Since the white ants cannot pass outward along the path along the bottom of the white ant intrusion preventing agent 28, the white ants can be prevented from entering the room.

  Further, as shown in FIG. 12C, when the white ants enter the pipe penetration portion from the outside through the outside of the inner pipe 106, they reach between the inner pipe 106 and the inner peripheral edge of the receiving plate 12. Even if the white ants try to move upward along the inner peripheral edge of the white ant intrusion preventing agent 28 from there, the white ant intrusion preventing agent 28 is lowered to a predetermined height at which the white ant intrusion preventing agent 28 can exert the ant preventing performance. The accumulation of the white ants prevents the white ants from entering the room because the white ants cannot pass upward along the path along the inner peripheral edge of the white ant intrusion preventing agent 28.

  Thus, also in the embodiment of FIG. 9, white ants that have entered the pipe penetration portion of the double pipe 102 such as the gap between the sheath pipe 104 and the concrete foundation 100 and the gap between the sheath pipe 104 and the inner pipe 104 enter the room. Intrusion can be prevented.

  In the embodiment of FIG. 9 as well, since the white ant intrusion preventing agent 28 is prevented from collapsing and moving by the outer periphery restricting portion 16, it is possible to maintain a reliable ant protection effect. Even after the ant protection system 10 is installed, the white ant intrusion preventing agent 28 can be visually confirmed, so that the white ant intrusion preventing agent 28 can be easily updated.

  Furthermore, in the embodiment of FIG. 9, the receiving plate 12 and the outer periphery restricting portion 16 are integrally formed and packaged as a white ants intrusion inhibitor integrated unit 30. The ant protection system 10 can be constructed simply by fixing it at a predetermined position on the horizontal surface 100a of the concrete foundation 100 and accumulating the white ant intrusion preventing agent 28 there. That is, as in the embodiment of FIG. 1, the distance between the outer peripheral edge of the receiving plate 12 and the outer peripheral restricting portion 16 so that the white ant penetration preventing agent 28 can be accumulated within a predetermined distance from the outer peripheral edge of the receiving plate 12. Since there is no need to perform the work of accurately measuring at the construction site, the workability is improved.

  Further, the ant protection system 10 according to still another embodiment of the present invention shown in FIG. 13 is different from the ant protection system 10 shown in FIG. Hereinafter, the ant protection system 10 shown in FIG. 13 will be described in detail, but the same reference numerals are used for the same parts as the ant protection system 10 shown in FIG. 1, and the description thereof is omitted or simplified.

  As shown in FIG. 13, the ant protection system 10 includes an opening 42, a receiving plate 12, and a white ant intrusion preventing agent 28. As shown in FIGS. 14 and 15, the opening 42 is a cylindrical opening formed in the horizontal surface 100 a of the concrete foundation 100, and from the horizontal surface 100 a of the pipe end concrete foundation 100 on the indoor side of the sheath tube 104, that is, It penetrates up to the indoor side receiving port 112 in the vertical direction.

  In the opening 42, the receiving plate 12 is provided around the inner tube 106. The receiving plate 12 is formed in a donut plate shape having an opening 14 at the center, and is fitted to the inner pipe 106 inside the opening 42 and is fitted to the indoor side receiving port 112 of the sheath pipe 104. Established. The inner diameter of the receiving plate 12 is set to be substantially equal to the outer diameter of the inner tube 106, and the outer diameter is set to be equal to or slightly smaller than the diameter of the indoor side receiving port 112 of the sheath tube 104. Is done.

  Further, in the opening 42, the white ant penetration preventing agent 28 is accumulated (filled) above the receiving plate 12. The white ant intrusion preventing agent 28 is, for example, a pointed glass piece, and is accumulated in the opening 42 so that the upper end thereof is flush with the horizontal surface 100 a of the concrete foundation 100.

  Since the periphery (periphery) of the opening 42 is surrounded by the concrete foundation 100, the outer periphery of the white ant intrusion preventing agent 28 is defined by the concrete foundation 100, and the maximum height at which the white ant intrusion preventing agent 28 can be accumulated is the concrete foundation. The height is defined according to the height difference between the horizontal surface 100a of 100 and the upper surface of the receiving plate 12 (that is, the length of the opening 42 in the vertical direction).

  That is, as shown in FIGS. 14 and 15, the height difference d5 between the horizontal surface 100a of the concrete foundation 100 and the upper surface of the backing plate 12 is such that the white ants move in the vertical direction along the path along the inside or the periphery of the white ant intrusion preventing agent 28. For example, it is set to 40 mm so that it can be prevented from passing through. By doing so, the white ant penetration preventing agent 28 is accumulated to a height of 40 mm. Moreover, since the indoor side receiving port 112 of the sheath pipe 104 has stood up above the receiving plate 12 in the outer side than that, the horizontal surface 100a of the concrete foundation 100 and the end surface of the indoor side receiving port 112 of the sheath pipe 104 (that is, The height d6 from the pipe end of the sheath pipe 104 to the horizontal surface 100a of the concrete foundation 100 is set to 30 mm, for example.

  Referring to FIGS. 14 and 16, in order to construct such an ant protection system 10 in the pipe penetration portion of the concrete foundation 100, first, as shown in FIG. In addition, the void pipe 130 is inserted into the indoor side receiving port 112 of the sheath pipe 104, and concrete is placed in the foundation formwork to form the concrete foundation 100. The void tube 130 is a straight tube formed of paper, and the outer diameter thereof is set to be equal to the diameter of the indoor side receiving port 112 of the sheath tube 104. When the concrete is dry, the void tube 130 is disassembled and removed from the concrete foundation 100. Then, an opening 42 is formed in the concrete foundation 100 as shown in FIG.

  Next, the receiving plate 12 is externally fitted to the inner pipe 106 exposed above the horizontal surface 100a of the concrete foundation 100, and the receiving plate 12 is inserted into the indoor side receiving port 112 of the sheath tube 104 (that is, the indoor side receiving port). 112 so as to be locked to the stopper 112. Then, the white ant penetration preventing agent 28 is accumulated (filled) above the receiving plate 12 in the opening 42, and a special solidifying agent is sprayed on the surface of the accumulated white ant penetration preventing agent 28 to be hardened. Thereby, construction of the ant-proof system 10 to the piping penetration part of the concrete foundation 100 is completed.

  By installing the ant protection system 10 in the pipe penetration portion of the concrete foundation 100 in this way, as shown in FIG. 17 (a), white ants entering the pipe penetration portion from the outside through the outside of the sheath tube 104 are removed. The path along the outer peripheral edge of the white ant intrusion preventing agent 28 (that is, the gap between the outer peripheral edge of the white ant intrusion preventing agent 28 and the concrete foundation 100) from the pipe end of the sheath pipe 104 (the end surface of the indoor receiving port 112) is upward. When the white ant intrusion prevention agent 28 is accumulated at a predetermined height at which the white ant intrusion prevention agent 28 can exhibit the ant prevention performance, the white ant can move along the outer peripheral edge of the white ant intrusion prevention agent 28. Since it is impossible to pass upward through the path, white ants can be prevented from entering the room.

  Also, as shown in FIG. 17 (b), white ants that have entered the pipe penetrating portion from the outside through the outside of the inner pipe 106 and reached between the inner peripheral edge of the receiving plate 12 and the inner pipe 106, The white ant intrusion preventive agent 28 is accumulated at a predetermined height at which the white ant intrusion preventive agent 28 can exhibit the ant preventive performance even if the path along the inner periphery of the white ant intrusion preventive agent 28 is advanced upward. Therefore, the white ants cannot pass upward along the path along the inner peripheral edge of the white ant intrusion preventing agent 28, so that the white ants can be prevented from entering the room.

  Thus, also in the embodiment of FIG. 13, white ants entering the pipe penetration portion of the double pipe 102 such as the gap between the sheath pipe 104 and the concrete foundation 100 and the gap between the sheath pipe 104 and the inner pipe 106 enter the room. Intrusion can be prevented.

  Further, since the white ant intrusion preventing agent 28 is prevented from collapsing and moving by the concrete foundation 100 around the opening 42, it is possible to maintain a reliable ant-proofing effect, and to prevent ant-proofing. Even after the system 10 is installed, the white ant intrusion preventing agent 28 can be visually confirmed, so that the white ant intrusion preventing agent 28 can be easily updated.

  Further, in the embodiment of FIG. 13, the ant protection system 10 can be constructed only by accumulating the white ant penetration preventing agent 28 in the opening 42 provided in the concrete foundation 100. That is, as in the embodiment of FIG. 1, the distance between the outer peripheral edge of the receiving plate 12 and the outer peripheral restricting portion 16 so that the white ant penetration preventing agent 28 can be accumulated within a predetermined distance from the outer peripheral edge of the receiving plate 12. Since there is no need to perform the work of accurately measuring at the construction site, the workability is improved.

  In each of the above-described embodiments, the white ant intrusion preventing agent 28 is accumulated so that the accumulated white ant intrusion preventing agent 28 does not move (scatter) beyond the outer periphery defining portion 16 to the outside. Later, the surface was solidified by spraying a special solidifying agent, but it is not necessary to be limited to this, and the mixture of the white ant intrusion preventing agent 28 and the special solidifying agent mixed in advance is collected. It may be.

  Furthermore, it is not always necessary to use a solidifying agent. For example, in the ant protection system 10 which is still another embodiment of the present invention shown in FIG. 18, a lid member 46 is provided above the accumulated white ant intrusion prevention agent 28. The lid member 46 prevents the movement of the white ant intrusion preventing agent 28. Hereinafter, the ant protection system 10 shown in FIG. 18 will be described in detail, but the same reference numerals are used for the same parts as the ant protection system 10 shown in FIG. 1, and the description thereof is omitted or simplified.

  As shown in FIG. 18, in the ant protection system 10, the receiving plate 12 is formed in a donut plate shape having an opening 14 in the center, and is externally fitted to the inner pipe 106 exposed above the horizontal surface 100 a of the concrete foundation 100. And disposed on the horizontal surface 100 a of the concrete foundation 100 and the upper end of the joint pipe 128.

  Further, an outer periphery defining portion 16 is provided on the horizontal surface of the concrete foundation 100 outside the receiving plate 12. In the vicinity of the upper end of the short cylindrical portion 18 of the outer periphery defining portion 16, as shown in FIGS. 19A and 19B, a plurality of (three in this embodiment) cuts that penetrate the short cylindrical portion 18 in the thickness direction. 44 is formed. The notches 44 are formed side by side at regular intervals in the circumferential direction, and claws 52 of a lid member 46 described later are fitted into the notches 44.

  Further, as shown in FIG. 18, white ant penetration preventing agents 28 are accumulated above and around the receiving plate 12. The white ant intrusion preventing agent 28 has a ring shape as a whole in a container-like space having an upper opening surrounded by the inner surface of the short cylindrical portion 18 of the outer periphery defining portion 16, the outer surface of the inner tube 106, and the horizontal surface 100 a of the concrete foundation 100. Are integrated as follows. The upper part of the white ant intrusion preventing agent 28 is covered with a lid member 46 so that the white ant intrusion preventing agent 28 does not move beyond the outer periphery defining portion 16 and outward.

  As shown in FIG. 20, the lid member 46 is made of a synthetic resin such as transparent vinyl chloride, includes a lid body 48 formed in a donut plate shape having an opening 50 in the center portion, and is externally fitted to the inner tube 106. At the same time, it is detachably installed near the upper end of the short cylindrical portion 18 of the outer periphery defining portion 16. That is, the inner tube 106 is inserted into the opening 50 of the lid main body 48, and the inner diameter of the lid main body 48 (that is, the diameter of the opening 50) is set substantially equal to the outer diameter of the inner tube 106. Specifically, the inner diameter of the lid body 48 is set such that the gap between the inner peripheral edge of the lid body 48 and the outer surface of the inner tube 106 is about 5 mm, for example, 100 mm. Moreover, the outer diameter of the lid body 48 is set to be smaller than the inner diameter of the outer periphery defining portion 16, and is 313 mm, for example.

  A plurality (three in this embodiment) of claws 52 are formed on the outer peripheral edge of the lid body 48 at positions corresponding to the notches 44 of the short cylindrical portion 18 described above. The claws 52 are formed at regular intervals in the circumferential direction of the lid main body 48, extend radially outward from the outer peripheral edge of the lid main body 48, and the notches 44 of the outer periphery defining portion 16 described above when the lid member 46 is installed. It is inserted in.

  Further, the lid body 48 is formed with a cutting portion (slit) 54 that extends from the inner edge to the outer edge that defines the opening 50 and divides the lid body 48 in the circumferential direction. The cutting part 54 is formed so as to divide one claw 52 of the plurality of claws 52 into two claw divided bodies 52a and 52b. When the cutting part 54 is closed, the two claw divided bodies 52a and 52b The claws 52 are formed by bonding.

  18-20, in order to construct such an ant protection system 10, the receiving plate 12 is externally fitted to the inner tube 106 exposed above the horizontal surface 100a of the concrete foundation 100, and the receiving plate 12 is thus fitted. Is placed on the horizontal surface 100 a of the concrete foundation 100 and the upper end of the joint pipe 128.

  Next, the outer periphery defining portion 16 is disposed at a position that secures a predetermined distance from the outer periphery of the backing plate 12, and the outer periphery defining portion 16 is fixed on the horizontal surface 100 a of the concrete foundation 100. Then, the white ant intrusion preventing agent 28 is accumulated in a container-like space having an upper opening surrounded by the inner surface of the short cylindrical portion 18, the outer surface of the inner pipe 106 and the horizontal surface of the concrete foundation 100, and the accumulated white ant intrusion preventing agent 28 is accumulated. The lid member 46 is installed so as to cover from above.

  Specifically, when the lid member 46 is installed, the inner pipe 106 (the other end of the first inner pipe portion 120) is already connected to an indoor drain pipe (that is, a joint or a joint). First, the lid body 48 is slightly elastically deformed to open the cutting portion 54, the inner tube 106 is accommodated in the opening 50 through the cutting portion 54, and the cutting portion 54 is closed to fit the lid member 46 to the inner tube 106. . Then, each claw 52 of the lid member 46 is fitted into each cut 44 of the short cylindrical portion 18 of the outer periphery defining portion 16, so that the lid member 46 is fixedly installed on the outer periphery defining portion 16. However, when the inner pipe 106 is not yet connected to the indoor drain pipe, the inner pipe 106 is inserted into the opening 50 of the lid main body 48 of the lid member 46 so that the lid member 46 is fitted to the inner pipe 106. It is good to make it.

  Thus, by installing the ant-proof system 10 in the piping penetration part of the concrete foundation 100, the clearance gap between the sheath pipe 104 and the concrete foundation 100, the sheath pipe 104, and the inner pipe 104, as in the embodiment of FIG. It is possible to prevent white ants that have entered the pipe penetration portion of the double pipe 102 such as a gap between

  Further, in this embodiment, the lid member 46 prevents the white ant penetration preventing agent 28 from moving beyond the outer periphery defining portion 16 to the outside. For this reason, it is not necessary to perform an operation of spraying a dedicated solidifying agent that hardens the accumulated white ants intrusion preventing agent 28, and the workability can be improved. In addition, since the movement of the white ant penetration preventing agent 28 can be prevented without depending on the duration of the effect of the solidifying agent, the life of the system 10 can be extended.

  Furthermore, in this embodiment, since the lid member 46 has transparency, it is possible to visually check the white ant intrusion preventing agent 28 even after the ant protection system 10 is installed. The intrusion prevention agent 28 can be easily updated. However, the lid member 46 is not necessarily formed of a synthetic resin having transparency.

  In this embodiment, instead of using the solidifying agent in the system 10 of the embodiment of FIG. 1, the lid member 46 is installed above the accumulated white ant intrusion preventing agent 28. However, the system 10 of the embodiment of FIG. It goes without saying that a lid member may be applied instead of using a solidifying agent in the system 10 of the embodiment of FIG.

  For example, when the lid member 46 is applied to the system 10 of the embodiment of FIG. 13, the notch 44 of the short cylindrical portion 18 of the outer periphery defining portion 16 and the claw 52 of the lid member 46 are not necessary, and are formed in a donut plate shape. The lid member 46 may be detachably fixed to the horizontal surface 100a of the concrete foundation 100 with an adhesive tape or the like.

  Further, in this embodiment, one cutting part 54 is formed in the lid body 48, the lid body 48 is slightly elastically deformed to open the cutting part 54, and the inner tube 106 is accommodated in the opening 50 through the cutting part 54. However, it need not be limited to this.

  For example, as shown in FIG. 21, two lids 48 may be formed in the lid body 48, and the lid body 48 may be configured by combining a first lid body 48a and a second lid body 48b. That is, the lid body 48 is formed with two cut portions 54 extending from the inner edge to the outer edge that define the opening 50, and the two cut portions 54 make the lid body 48 a substantially semi-disc-shaped first lid body 48 a. It is divided into a second lid body 48b. When the first lid body 48a and the second lid body 48b are combined so that the two cutting portions 54 are closed, the opening 50 is formed at the center of the lid body 48. For example, four claws 52 are formed side by side in the circumferential direction on the outer peripheral edge of the lid body 48, and the cutting part 54 divides the two claws 52 of the plural claws 52 into two claws 52 a and 52 b. The claw 52 is formed by joining the two claw division bodies 52a and 52b when the cutting portion 54 is closed. By doing so, each lid body 48a can be fixed to the short cylindrical portion 18 of the outer periphery defining portion 16 by itself. However, the first lid main body 48a and the second lid main body 48b may be joined by an adhesive tape or the like without the two claw division bodies 52a and 52b joining to form the claw 52.

  Further, as shown in FIG. 22, auxiliary claws 56 are formed on both sides of the two claw division bodies 52a and 52b, respectively, and the auxiliary claw 56 together with the claw division bodies 52a and 52b is formed in the short cylindrical portion 18 of the outer periphery defining portion 16. You may make it fit in each notch 44 of this. In this case, the lid member 46 can be more stably installed on the outer periphery defining portion 16.

  Furthermore, as shown in FIG. 23, an easy-to-cut portion 58 may be formed concentrically around the opening 50 of the lid body 48 of the lid member 46. For example, the easy cutting portion 58 is formed with a thin portion or a perforated cut at predetermined intervals, and the operator can easily cut the lid main body 48 by hand along the easy cutting portion 58. Is possible. In this case, the diameter of the opening 50 of the lid main body 48 can be changed by cutting (removing) the inner peripheral side of the lid main body 48 along the easy-to-cut portion 58 in accordance with the diameter of the inner tube. Therefore, it is possible to install a common lid member 46 for a plurality of inner pipes having different sizes, and it is possible to reduce the types of products and the amount of inventory. Although not shown, the easy-to-cut portion 58 can also be formed on the backing plate 12.
