Description

  The present invention relates to a termite control method for preventing termite invasion by filling a paste composition containing a termite control agent into a gap formed in an abutting part of an underfloor structure of a building, and in particular, The present invention relates to a method for once constructing a termite-preventing structure for preventing the invasion of termites, and then again constructing it.

  Conventionally, for the purpose of preventing building damage by termites, such as spraying an anti-termite chemical on the floor base plate surface, or installing a so-called dovetail made of metal between soil concrete and basic concrete during construction, etc. The way is done.

  However, in the former method of spraying the termite control agent, the termite control agent penetrates underground to contaminate groundwater, or the termite control agent flows out to the outside due to submersion under the floor. In addition to the above problems, it is difficult to maintain the termite control effect of termite control agents over a long period of time. On the other hand, the latter method by ant-return has a problem that it is not possible to effectively prevent termites from bypassing the ant-return and entering the wooden member of the building.

  As a technique for solving the above problem, for example, Patent Document 1 proposes a termite invasion preventive agent that uses an anti-termite agent and a latex-containing aqueous emulsion at the contact portion of the underfloor structure of a building.

  The termite invasion preventive agent disclosed in Patent Document 1 is a paste, and can be expected to have good workability in that it can be filled in a container such as a tube and applied at a construction site. Further, the paste-like termite invasion preventive agent has an advantage that the applied amount can be easily grasped. Further, since the termite invasion preventive agent has a good fluidity, the termite prevention effect can be maintained for a long period of time by easily filling the gap formed between the soil concrete and the foundation concrete.

JP 2001-299181 A

  The termite invasion preventive agent disclosed in Patent Document 1 exerts an anti-termite effect by adding an anti-termite agent to the latex-containing aqueous emulsion, and the drug efficacy of the termite-preventive agent can be maintained for about 10 years. However, after the termite invasion preventive agent is used to construct the termite control structure, the drug efficacy of the termite control agent gradually decreases as time passes, and eventually it becomes necessary to reconstruct the termite control structure. Hereinafter, a paste composition such as the above-mentioned latex-containing aqueous emulsion containing a termite-preventing agent is referred to as a "termite-preserving agent-containing paste".

  In reconstructing the termite control structure so far, all of the dried and hardened termite control agent-containing paste was removed from the location of the termite control structure constructed the first time, and a new termite control agent was added to the removed location. It is usual to apply the contained paste and re-construct. However, if the dovetail structure is reconstructed by such a method, the work becomes complicated and the work time becomes long.

  The present invention has been made in view of such circumstances, and its purpose is to fill a ant-preventive agent-containing paste in a gap formed in the abutting portion of the underfloor structure and perform an anti-termite structure. An object of the present invention is to provide a ant-proof construction method capable of efficiently completing the work by simple work without lowering the ant-proof effect when reconstructing the ant-proof structure.

  The present inventors have made repeated studies from various angles in order to solve the above problems. As a result, an amount of paste containing an anti-termite agent corresponding to the rate of extinguishing the termite-repellent agent in the area where the termite-repellent structure was built up to the previous time was applied so as to cover the area where the termite-repellent structure was built last time. The present invention has been completed by finding out that the above-mentioned problems can be solved by reconstructing the termite-proof structure after the first time, and further studying based on such knowledge.

  That is, according to one aspect of the present invention, after the ant-proof structure is constructed by filling a gap formed in the abutting part of the underfloor structure with the ant-proof agent-containing paste, the ant-proof structure is re-applied once or more. In doing so, apply an anti-termite agent-containing paste in an amount corresponding to the rate of extinguishing the anti-termite agent in the area in which the termite structure was built up to the previous time, and apply it so as to cover the area in which the termite structure was built last time. The feature is that the ant-proof structure after the first time is reconstructed.

  In the method for reconstructing the termite control of the present embodiment, the termite control agent-containing paste used each time is preferably colored in a different color.

  According to the present invention, after the ant-preventive structure is constructed by filling the gap formed in the abutting portion of the underfloor structure with the ant-preventive agent-containing paste, the ant-repellent structure is re-applied when it is reconstructed. It is possible to provide a termite proof construction method capable of efficiently completing a work by a simple work without lowering the effect.

FIG. 8: is explanatory drawing which shows typically each embodiment at the time of performing re-construction of a ant-proof structure twice.

  In the method of applying an ant-prevention method according to the present embodiment, the ant-preventive structure is first constructed by filling the space formed in the contact portion of the underfloor structure with the ant-preventive agent-containing paste to construct the first ant-preventive structure. When reconstructing more than one time, cover the area where the previous termite control structure was constructed with the amount of paste containing the termite control agent that was equivalent to the rate at which the termite control agent disappeared in the area where the termite control structure was constructed. It is characterized in that it is applied and the second and subsequent ant-proof structures are reconstructed.

  Hereinafter, the dovetail proof construction method of this embodiment will be described with reference to the drawings. Needless to say, the following ant-proof construction method is merely an example of the method of the present invention and is not intended to be limited to this.

  FIG. 1 is a schematic explanatory view showing an example of an anti-termite structure when a first anti-termite structure is constructed by filling a gap formed in the abutment part of the underfloor structure with an anti-termite agent-containing paste. . The gap formed in the contact portion of the underfloor structure of the building is a gap formed between the soil concrete and the basic concrete, as shown in FIG. 1.

  In FIG. 1, 1 is a concrete cloth foundation (basic concrete), 2 is soil concrete, 3 is a moisture-proof sheet which is interposed between the ground surface and the soil concrete 12, and is made of, for example, polyethylene (PE) or the like. Reference numeral 4 shown in FIG. 1 indicates a paste containing an anti-termite agent. The moisture-proof sheet 3 is not particularly limited as long as it is a moisture-proof sheet used for the purpose of moisture-proof, and may be an anti-termite / moisture-proof sheet containing an anti-termite agent and having an anti-termite performance.

  The termite-preventing agent-containing paste 4 is adjusted to have good fluidity, and when the termite-preventing agent-containing paste 4 is applied, as shown in FIG. The space and the concrete 2 are filled without any gap. Further, when the paste 4 containing an anti-termite agent is applied, the paste 4 containing the anti-termite agent is expected to have high fluidity, so that the paste 4 is relatively thickly filled. After being filled with the ant-preventive agent-containing paste 4, it is filled so that a thickness of at least 5 mm can be secured after drying and curing in consideration of shrinkage after drying and curing, variation in construction, and the like. For example, d1 is secured at about 7 to 8 mm at a location where the amount of shrinkage is greatest (where the maximum thickness d1 shown in FIG. 2 is reached). In order to maintain such a state, the rising height h1 of the ant-anticide-containing paste 4 on the concrete cloth foundation 1 side and the width w1 on the soil concrete 12 side are both about 20 mm. In order to ensure the above-mentioned state, it is preferable to appropriately adjust the viscosity of the termite-preventing agent-containing paste 4.

  FIG. 2 is a plan perspective view showing the configuration of a filling nozzle used for filling the paste 4 containing an antitermite agent when constructing the termite structure shown in FIG. The filling nozzle 5 is formed so that the nozzle opening 5a is a right triangle in a plan view.

  FIG. 3 (schematic explanatory diagram) shows a state in which the gap 4 formed in the contact portion of the underfloor structure is filled with the termite proofing agent-containing paste 4 using the filling nozzle 5 as described above. The filling nozzle 5 is used by being attached to the tip of the tube 6 containing the ant-preventive agent-containing paste 4, and is provided in a gap formed in the abutting portion of the underfloor structure corresponding to the shape of the nozzle opening 5a. The paste 4 containing the anti-termite agent is smoothly filled.

  FIG. 4 is a schematic explanatory view showing an example of the ant-proof structure when the re-construction of the ant-proof structure is performed once. After constructing the termite control structure shown in FIG. 1, the efficacy of the termite control agent gradually decreases, and eventually it becomes necessary to reconstruct the termite control structure. When reconstructing the termite control structure, the termite control agent-containing paste 4a is applied so as to cover the area in which the last termite control agent structure was constructed (the area filled with the termite control agent-containing paste 4), and the termite control structure was applied. Reconstruct. In this re-construction, the paste 4a containing the anti-termite agent is applied in an amount corresponding to the rate of disappearance of the anti-termite agent in the paste 4 containing the anti-termite agent previously filled. The rising height h2 of the ant-anticide-containing paste 4a on the concrete cloth foundation 1 side and the width w2 of the soil concrete 2 side are the criteria for grasping the application amount of the ant-anticide-containing paste 4a. Will be described later.

  FIG. 5 is a schematic explanatory view showing an example of the ant-proof structure when the ant-proof structure is reconstructed twice. After re-applying the ant-proof structure shown in FIG. 4, when re-applying the ant-proof structure, cover the area where the previous ant-proof structure was constructed (the area where the ant-preventive-agent-containing paste 4a was applied). The anti-termite containing paste 4b is applied and the anti-termite structure is reconstructed. In this re-construction, an amount of the termite control agent containing paste 4b was applied in an amount corresponding to the rate of disappearance of the termite control agent in the area where the termite control structure was built up to the previous time (including the area filled with the termite control agent containing paste 4). To do. The rising height h3 of the ant-anticide-containing paste 4b on the concrete cloth foundation 1 side and the width w3 of the soil concrete 2 side are the criteria for grasping the application amount of the ant-anticide-containing paste 4b. Will be described later.

  FIG. 6 is a plan perspective view showing a configuration of a coating nozzle used for coating the termite-preventing agent-containing pastes 4a and 4b when reconstructing the termite-proof structure. The coating nozzle 7 has a nozzle opening 7a formed in a substantially rectangular shape in a plan view.

  When the paste 4a or 4b containing the ant-preventive agent is applied using such an application nozzle 7, the tube 6 (containing the paste 4a or 4b containing the ant-preventive agent is stored as in the case shown in FIG. It is used by attaching it to the tip of (not shown), so that the anti-termite containing paste 4a or 4b can be easily applied even to a relatively flat surface according to the difference in the shape of the nozzle opening 7a. Has been done.

  In the ant-repellent construction method of the present embodiment, the area in which the ant-repellent structure has been constructed last time is covered with the ant-anticide-containing paste in an amount corresponding to the rate at which the ant-repellent has disappeared in the area where the ant-repellent structure has been constructed up to the previous time. Apply and re-install. The period until re-construction will be about 10 years, and re-construction will be carried out appropriately during that period, but at the time of re-construction, it is necessary to grasp the rate of ant-repellent disappearance in the area where the ant-preventive structure was constructed up to the previous time. is there.

  The rate of disappearance of the termite control agent in the area where the termite control structure was constructed up to the previous time was determined by liquid chromatography using a sample obtained by collecting a part of the termite control agent-containing paste in the area and dissolving it in a solvent. Can be measured by The rate of disappearance of the termite control agent varies depending on the type of paste composition, the type of termite control agent, etc., but the rate of disappearance over 10 years is the initial content in the area where the termite control structure was built up to the previous time. However, it is about 30 to 70% (that is, the remaining rate is about 70 to 30%). Next, with reference to the drawings, a description will be given of a situation in which re-construction is performed by using an amount of the paste containing an anti-termite agent that corresponds to the rate of disappearing the termite-preventive agent in the area where the termite-proof structure was constructed up to the previous time.

  FIG. 7: is explanatory drawing which shows typically each embodiment at the time of re-constructing an ant-proof structure once. The “unit” of the numerical values shown in FIG. 7 is “mm”. For example, “20” and “6” shown in FIG. 7A indicate that the height h1 shown in FIG. 1 is 20 mm and the height h2 shown in FIG. 2 is 6 mm, respectively. ing. Although not shown in FIG. 7A, the width w1 shown in FIG. 1 and the width w2 shown in FIG. 4 correspond to the heights h1 and h2 shown in FIG. That is, the width w1: 20 mm and the width w2: 6 mm) are adopted. These points also apply to FIG. 8 described later.

  In the following description, the termite control agent content rate at the initial filling stage (before disappearance) is set to 100% in the region where the first termite control structure is constructed (the region of the termite control agent-containing paste 4), and re-construction is performed. It is premised that the type and content of the termite control agent in the termite control agent-containing paste used at this time are substantially the same as the above-mentioned "termite control agent content at the initial stage of filling". However, if it is expected that the same ant-repellent effect will be exerted on the ant-anticide, the kind of ant-anticide contained in the paste 4, 4a, 4b may be different. Alternatively, various anti-termite agents may be used in combination. In short, at the time of re-construction, it is only necessary to secure the content of the termite control agent equivalent to that at the initial stage of filling (before disappearance).

  The state shown in FIG. 7 (a) is when the termite control agent in the termite control agent-containing paste 4 disappears by 30% before the termite control structure is reconstructed (that is, when the residual rate of the termite control agent is 70%). ) Is assumed. Since the termite advances toward the pillar, it is important to apply the termite-preventing agent-containing paste 4a so as to extend a distance in the vertical direction in order to prevent the termite from entering. From this point of view, the termite-preventing agent-containing paste 4 is prepared in such a manner that the content of the termite-preventing agent-containing paste 4 becomes 30% of the height h1 of 20 mm (20 mm × 0.3 = 6 mm). The paste 4a containing the ant-preventive agent is overcoated on the top. As described above, by repeatedly applying the ant-preventive agent-containing paste 4a, it is possible to apparently secure the ant-antagonist content rate equivalent to that at the initial stage of filling in the region where the first termite-proof structure is constructed.

  The state shown in FIG. 7B assumes that the termite control agent in the termite control agent-containing paste 4 has disappeared by 50% before re-construction (that is, the residual rate of termite control agent is 50%). There is. In this case, the termite-preventing agent-containing paste 4 is used so that the amount of the termite-preventing agent content has disappeared, that is, the height h1 is 50% of 20 mm (20 mm × 0.5 = 10 mm). The paste 4a containing the ant-preventive agent is overcoated on the above. As described above, by repeatedly applying the ant-preventive agent-containing paste 4a, it is possible to apparently secure the ant-antagonist content rate equivalent to that at the initial stage of filling in the region where the first termite-proof structure is constructed.

  The state shown in FIG. 7C assumes a case where 70% of the termite control agent in the termite control agent-containing paste 4 has disappeared before the re-construction (that is, the remaining rate of the termite control agent is 30%). There is. In this case, the termite control agent-containing paste 4 is adjusted so that the content of the termite control agent disappears, that is, the height h1 becomes 70% of 20 mm (20 mm × 0.7 = 14 mm). The paste 4a containing the ant-preventive agent is overcoated on the above. As described above, by repeatedly applying the ant-preventive agent-containing paste 4a, it is possible to apparently secure the ant-antagonist content rate equivalent to that at the initial stage of filling in the region where the first termite-proof structure is constructed.

  FIG. 8: is explanatory drawing which shows typically each embodiment at the time of performing re-construction of a ant-proof structure twice. FIG. 8 (a) assumes that the second re-work is performed after the first re-work in FIG. 7 (a), and FIG. 8 (b) is the same as the first re-work in FIG. 7 (b). It is assumed that the second re-construction is performed after the second re-construction, and FIG. 8C shows that the second re-construction is performed after the first re-construction in FIG. 7C. It is assumed.

  In the state shown in FIG. 8A, it is assumed that the content rate of the termite control agent in the termite control agent-containing paste 4 is further halved in 5 years from the first re-construction to the second re-construction (that is, This shows the case where the remaining rate of the termite control agent is 35%). In this case, the amount of the termite-preventing agent in the termite-preventing agent-containing paste 4 (35%) should be obtained, that is, the height h2 should be 35% of 20 mm (20 mm × 0.35 = 7 mm). As described above, the termite-preventing agent-containing paste 4b is applied over the termite-preventing agent-containing paste 4a. In this manner, by repeatedly applying the ant-preventive agent-containing paste 4b, the ant-antagonist content rate that is apparently equal to the initial filling rate in the region where the first ant-repellent structure is constructed is obtained.

  In the second re-construction, the term ant-preventive agent disappearance rate in the ant-preventive-agent-containing paste 4a in the first re-construction is also taken into consideration. However, as compared with the rate of disappearance of the termite-preventing agent from the termite-preventing agent-containing paste 4 before re-construction, the rate of elimination of the termite-preventing agent from the termite-preventing agent-containing paste 4a after the first re-construction is small, and When the amount of the termite-preventing agent-containing paste 4b corresponding to the rate of elimination of the termite-preventing agent from the termite-containing agent-containing paste 4 is applied, the rate of elimination of the termite-preventing agent from the termite-preventing agent-containing paste 4a applied in the first re-construction is It can be sufficiently compensated (the same applies to FIG. 8B and FIG. 8C).

  In the state shown in FIG. 8B, it is assumed that the content of the termite control agent in the termite control agent-containing paste 4 is further halved in the five years from the first re-construction to the second re-construction (that is, This shows the case where the remaining rate of the termite control agent is 25%). In this case, the amount of the termite-preventing agent in the termite-preventing agent-containing paste 4 (25%) should be obtained, that is, the height h2 should be 25% of 20 mm (20 mm × 0.25 = 5 mm). As described above, the termite-preventing agent-containing paste 4b is applied over the termite-preventing agent-containing paste 4a. In this manner, by repeatedly applying the ant-preventive agent-containing paste 4b, the ant-antagonist content rate that is apparently equal to the initial filling rate in the region where the first ant-repellent structure is constructed is obtained.

  In the state shown in FIG. 8C, it is assumed that the content of the termite control agent in the termite control agent-containing paste 4 is further halved in the five years from the first reconstruction to the second reconstruction (that is, This is based on the assumption that the remaining rate of the ant-preventive agent is 15%). In this case, the amount of the termite control agent disappearance rate (15%) in the termite control agent-containing paste 4 should be set to an amount corresponding to 15% of the height h2 of 20 mm (20 mm × 0.15 = 3 mm). As described above, the termite-preventing agent-containing paste 4b is applied over the termite-preventing agent-containing paste 4a. In this manner, by repeatedly applying the ant-preventive agent-containing paste 4b, the ant-antagonist content rate that is apparently equal to the initial filling rate in the region where the first ant-repellent structure is constructed is obtained.

  In the above description, the embodiment in which the rework is performed twice has been described, but the number of times of the rework is not limited to two, and needless to say, the number of rework may be three or four or more. Also, the period until re-construction may be appropriately selected according to the type of the termite control agent.

  The kind of the paste composition used in the ant-preventive construction method of the present embodiment is not particularly limited as long as a paste containing the ant-preventive agent-containing paste can be obtained, and is proposed in, for example, Patent Document 1 above. As described above, a latex-containing aqueous emulsion may be included. This latex-containing aqueous emulsion is a paste in which water latex is dispersed, contains water and latex as essential components, and can form a rubber elastic coating. The pasty composition used in the method for reconstructing the termite according to the present embodiment is not limited to the latex-containing aqueous emulsion as described above, and may contain a resin such as an alkyl acrylate resin as a main component.

  Additives that are usually used can be added to the ant-anthidrant-containing paste used in the ant-anterior reconstructing method of the present embodiment as long as the characteristics are not impaired. Examples of such additives include inorganic pigments (luminium hydroxide, titanium oxide, carbon, etc.), organic pigments (phthalocyanine blue, etc.), pigment dispersants (sodium tripolyphosphate, etc.), fillers (calcium carbonate, silica, diatomaceous earth, etc.). ), Dispersants (sodium polyacrylate, sodium hexametaphosphate, etc.), antiaging agents (aldehyde / ketone / amine reaction products and their derivatives, etc.), antiseptic / antifungal agents [cyclic nitrogen-sulfur compounds (BIT: 1, 2-Benzisotyiazolin-3-one), isothiazoline-based compound] and the like can be added. When these additives are added, it is preferable to use 5% by mass or less alone or in total. Among them, the inorganic pigments and the organic pigments are useful for coloring various colors in the ant-preservative-containing paste.

  As the termite-preventing agent in the termite-preventing agent-containing paste, concrete is strongly alkaline, so a phosphorus-based termite-preventing agent that is modified by alkali cannot obtain the desired drug effect, which is not preferable. Therefore, even when the anti-termite composition is brought into contact with concrete, an anti-termite agent having a desired anti-termite effect can be obtained, for example, a non-ester pyrethroid type drug (silafluofine, etophine prox, etc.), a pyrethroid type drug (permethrin, It is recommended to use allethrin, tralomethrin, bifenthrin, etc., carbamate drugs (proboxur, phenobcarb, sebin, etc.), triazine drugs (tripropyl isocyanurate, etc.), neonicotinoid drugs (imidacloprid, etc.). These can be used alone or in combination of two or more. The content of the termite-preventing agent in the termite-preventing agent-containing paste is preferably about 0.05 to 2.0% by mass based on the total weight of the termite-preventing agent-containing paste in consideration of its effect and cost.

  The termite control agent-containing paste used in the termite control method of the present embodiment is basically a paste having good fluidity, and the viscosity can be adjusted by changing the compounding amount of the various additives. The termite-containing pace used in the termite-preventing construction method of the present embodiment preferably has a viscosity at room temperature (25 ° C.) of about 70 to 120 Pa · S. If this viscosity is too high, the filling and coating properties of the paste containing an anti-termite agent will deteriorate. When the viscosity is too low, "dripping" occurs after filling or applying the ant-preservative-containing paste, and it becomes difficult to secure a predetermined amount of the ant-anticide-containing paste after drying. However, it is useful to make the viscosity different between the ant-repellent-containing paste when the first ant-preventive structure is constructed and when the ant-antagonist-containing paste is reconstructed. That is, the viscosity of the termite-preventing agent-containing paste when constructing the first termite-controlling structure is increased within the above range, and the viscosity of the termite-preventing agent-containing paste when reconstructing the termite controlling structure is within the above range. It is useful to improve the workability by lowering the value. For example, the first time is preferably 100 to 120 Pa · S, and the re-construction is preferably about 70 to 110 Pa · S.

  Although the outline of the present invention has been described above, the dovetail proof construction method of the present embodiment is summarized as follows.

  The ant-proof construction method of the present embodiment is such that the ant-proof structure is constructed by filling the gap formed in the abutment part of the underfloor structure with the ant-proof agent-containing paste and then re-doing the ant-proof structure once or more. At the time of construction, with an amount of paste containing an anti-termite agent corresponding to the rate of extinguishing the termite-proof agent in the area where the termite-proof structure was built up to the previous time, applying it so as to cover the area where the termite-proof structure was built last time, The feature is that the ant-proof structure after the second time is reconstructed.

  By adopting such a configuration, it is possible to provide a dovetail preventive construction method capable of completing the work efficiently by a simple work without lowering the dovetail preventive effect. In addition, since the paste containing an anti-termite agent is applied, there is an advantage that the shape of the applied area remains after application and drying, and the applied amount can be easily grasped. Moreover, by reapplying the paste containing an anti-termite agent on the area where the previous termite-proof structure was constructed, it is possible to further suppress the disappearance and bleeding of the termite-preventing agent, and to extend the period in which the termite-proofing effect can be exerted. it can.

  In addition, in the method of applying an anti-termite of the present embodiment, it is preferable that the anti-termite agent-containing paste used each time is colored in a different color. By appropriately adjusting the types and blending amounts of the above-mentioned inorganic pigments and organic pigments, various colors such as gray color, orange color, and light yellow color can be applied to the ant-preservative-containing paste. By adopting such a configuration, it is possible to confirm the number of times of rework.
