Description
本発明は、既設の建築物に対して有効な白蟻の防除方法に関する。 The present invention relates to a method for controlling white ants effective for an existing building.
既に建築された家屋等の建築物における白蟻の防除対策としては、従来より床下の周囲
を布基礎で囲まれた土間、または土間をコンクリートで固めたコンクリート間と称する所
に、白蟻駆除用の液薬を噴霧したり、同様の固形薬剤を内蔵した白蟻捕獲器を設置したりすることが行なわれている。
As a countermeasure against white ants in buildings such as houses that have already been built, conventional white ant control liquids have been used in places called the soil between soils surrounded by cloth foundations, or between concrete that has been solidified with concrete. The spraying of medicines and the installation of white ant traps containing similar solid medicines are carried out.
すなわち、白蟻は、一般的に、高温多湿で暗黒の条件を好むことから、この条件に適した土中に多くが生存する。そして、土中から家屋床下の土間（コンクリート間）へと侵入し、ここから布基礎（特に四隅のコーナー部）を伝って上方へ這い上がるいわゆる蟻道（ありみち）を形成して、最終的に布基礎上に組まれた土台等の木造建材に被害を及ぼすのである。 In other words, white ants generally prefer high-temperature, high-humidity and dark conditions, and many of them survive in soil suitable for these conditions. Then, it penetrates from the soil into the soil below the floor of the house (concrete between the concrete) and forms a so-called ant road that rises up from here through the fabric foundation (especially at the corners of the four corners). It damages wooden building materials such as foundations built on the fabric foundation.
しかしながら、上記した従来の対策は、いずれも白蟻の駆除を薬剤に頼るものであったため、その薬効が失われると、白蟻被害を全く予防することができなかった。したがって、薬効が失われるまでの短期間に、同様の対策を繰り返し行なう必要があった。 However, since all of the conventional measures described above rely on drugs for extermination of white ants, damage to white ants could not be prevented at all if their medicinal effects were lost. Therefore, it was necessary to repeat the same measures in a short period until the medicinal effect is lost.
本発明は、従来のこのような問題を解決するためになされたものであり、既設建築物の土間（コンクリート間）に侵入する白蟻を、薬剤に頼らず、機械的手段で長期間に亙って防御し得る方法を提供するとともに、上記土間（コンクリート間）に侵入した白蟻を効率的に捕獲し、殺虫する方法を併せて提供することを目的とする。 The present invention has been made in order to solve such a conventional problem, and white ants that penetrate into the soil (between concrete) of an existing building are used for a long time by mechanical means without relying on chemicals. It is an object of the present invention to provide a method for efficiently capturing and killing white ants that have entered the space (between concrete).
上記目的を達成する本発明の方法は、床下の土間または土間をコンクリートで固めたコンクリート間を囲み、建築物の各壁面を地上に支持する布基礎の四隅コーナー部を含む内面全周（間仕切り周囲および玉石周囲を含む）に、所要幅で厚さ０．０２ｍｍ〜２．００ｍｍの表面処理鋼板又は冷延鋼板からなる薄鋼板を、布基礎の下部に数センチ程度の隙間を残して貼り付けて、該布基礎を這い上がる白蟻を滑落させることにより、蟻道の形成を阻止することを特徴とする。
The method of the present invention that achieves the above object is to surround the entire inner circumference including the four corner corners of the fabric foundation that surrounds the soil below the floor or between the concrete solidified with concrete and supports each wall surface of the building on the ground. And a thin steel plate made of a surface-treated steel plate or cold-rolled steel plate having a required width of 0.02 mm to 2.00 mm and a gap of about several centimeters is left below the fabric foundation. The formation of ant roads is prevented by sliding down the white ants scooping up the cloth foundation.
この場合、布基礎にて囲まれた床下の土間または土間をコンクリートで固めたコンクリート間には、白蟻侵入用のスリットを備える容器内に、白蟻誘引剤と、白蟻の餌となる白蟻殺虫薬を含浸させたセルローズ系ロール紙とを収容してなる白蟻防除装置を、所要数設置しておくのが良い。 In this case, between the soil under the floor surrounded by the fabric foundation or between the concrete solidified with concrete, a white ant attractant and a white ant pesticide serving as a white ant's bait are placed in a container with a white ant intrusion slit. It is preferable to install a required number of white ant control devices that contain the impregnated cellulose-based roll paper.
また、本発明法において、薄鋼板を、布基礎の内面全周に貼り付けるに際して、布基礎の下部に数センチ程度の隙間を残しておくのは、当該薄鋼板の湿気による腐蝕を防止するためである。
Further, in the present invention method, a thin steel sheet, when pasting the entire circumference inner surface of the fabric foundation of leaving a gap of about several centimeters at the bottom of the fabric foundation, in order to prevent corrosion due to moisture in the thin steel sheet it is.
さらに、本発明法で使用する薄鋼板を、厚さ０．０２ｍｍ〜２．００ｍｍの表面処理鋼板又は冷延鋼板としたのは、厚さ０．０２ｍｍ以下では、長期（３年以上）の耐腐食性が得られず、２．００ｍｍ以上では、施工時における加工性、ハンドリング性等が悪化し、施工作業が困難となるからである。とりわけ、厚さ０．０６ｍｍの「アルジンク」と称する表面処理鋼板や冷延鋼板（冷延ＦＨ鋼板、冷延焼鈍鋼板）は、施工時における折り曲げや鉄挟みによる裁断等の加工性に優れ、しかも作業員が上を歩いてもアルミ箔のように容易に破損しない強度を備えているので、狭い床下でのこの種の使用に適しており、推奨される。
Further, a thin steel sheet for use in the present invention method, to that the surface-treated steel sheet or cold-rolled steel plate having a thickness of 0.02mm~2.00mm is hereinafter thickness 0.02 mm, resistance to long-term (more than 3 years) This is because the corrosiveness is not obtained, and if it is 2.00 mm or more, the workability and handling properties at the time of construction deteriorate, and the construction work becomes difficult. In particular, the surface treated steel sheet and cold-rolled steel sheet (cold-rolled FH steel sheet, cold-rolled annealed steel sheet) called “Alzinc” with a thickness of 0.06 mm are excellent in workability such as bending at the time of construction or cutting by iron pinching. It is suitable and recommended for this type of use under narrow floors, as it has the strength to not break easily as an aluminum foil when an operator walks on it.
上記構成よりなる本発明の方法によれば、土間またはコンクリート間を囲む布基礎の四隅コーナー部を含む内面全周に貼り付けられた薄鋼板は、硬くて、表面の平坦度が高い滑らかな材質であるから、土中から土間（コンクリート間）に侵入した白蟻が布基礎を伝って上方へ這い上がろうとしても、当該薄鋼板で滑って、滑落する。したがって、白蟻は布基礎に蟻道を形成することができず、布基礎上に構築された木造の土台や壁材等を長期に亙って白蟻の被害から防御することができる。 According to the method of the present invention having the above-described configuration, the thin steel plate attached to the entire inner surface including the four corner corners of the cloth foundation surrounding the soil or the concrete is hard and is a smooth material having a high surface flatness. Therefore, even if a white ant that has entered the soil (between concrete) from the soil tries to climb upward through the cloth foundation, it slides on the sheet steel and slides down. Therefore, the white ants cannot form an ant path on the cloth foundation, and can protect against the damage of the white ants over a long period of time, such as a wooden base or wall material constructed on the cloth foundation.
また、上記の本発明法に加えて、土間またはコンクリート間に白蟻防除装置を設置した場合には、当該土間またはコンクリート間に侵入した白蟻は、まずその大半が誘引剤に引き寄せられて白蟻防除装置内に捕獲され、かつ、捕獲された白蟻が好物であるセルローズ系ロール紙を食べることにより殺虫される。したがって、布基礎を這い上がろうとする白蟻の数自体が著しく減少するから、さらに蟻道の形成が困難となり、一層長期間に亙って布基礎上に構築された木造建築材を白蟻の被害から防御することができる。 Further, in addition to the above-mentioned method of the present invention, when a white ant control device is installed between the soil or the concrete, most of the white ants entering the space or between the concrete are first attracted to the attractant and the white ant control device. The insects are caught inside and eat the cellulosic roll paper, which is a favorite of the captured white ants. Therefore, since the number of white ants trying to scoop up the fabric foundation is significantly reduced, it becomes more difficult to form ant roads, and the wooden building materials constructed on the fabric foundation for a longer period of time are damaged by white ants. Can defend against.
以下、本発明の実施形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図１、図２は、既設の木造建築物に本発明の方法を実施した一例であり、１は土間または土間をコンクリートで固めたコンクリート間（以下、単に土間という）、４は布基礎、５は薄鋼板を示している。 FIG. 1 and FIG. 2 show an example in which the method of the present invention is applied to an existing wooden building, where 1 is a soil or a concrete between which the soil is hardened with concrete (hereinafter simply referred to as a soil), 4 is a cloth foundation, 5 Indicates a thin steel plate.
すなわち、布基礎４は、床下の土間１を囲み、家屋を構成する木造の土台２や壁材３を地上に支持するコンクリート造の台である。本発明法では、この土間１を囲む布基礎４の四隅コーナー部４’を含む内面全周に、所要幅の薄鋼板５を貼り付けている。 That is, the cloth foundation 4 is a concrete base that surrounds the soil 1 under the floor and supports the wooden base 2 and the wall material 3 constituting the house on the ground. In the method of the present invention, a thin steel plate 5 having a required width is attached to the entire inner circumference including the four corner portions 4 ′ of the cloth foundation 4 surrounding the space 1.
薄鋼板５は、これを貼り付ける布基礎４の高さＴに応じて幅Ｗ１００ｍｍ〜２００ｍｍの所要長さの帯状に切断加工したものであり、布基礎４への貼り付けは、帯状にした薄鋼板５の一面側全体、および布基礎４の薄鋼板５貼り付け部位の双方に建築内装用ボンド、例えば市販品の「速乾ボード ニューＧ７８」を塗布し、薄鋼板５の一面側を布基礎４の内面に密着させることによって行なわれている。また、この貼り付けに際しては、布基礎４の下部に高さ１〜３ｃｍ程度の隙間６を残すことにより、貼り付けた薄鋼板５の湿気による腐蝕を防止している。 The thin steel plate 5 is cut into a strip having a required length of width W 100 mm to 200 mm in accordance with the height T of the fabric foundation 4 to which the thin steel plate 5 is to be attached. Apply a bond for architectural interior, for example, “Quick Dry Board New G78”, to both the entire surface of the steel plate 5 and the thin steel plate 5 pasting portion of the fabric base 4, and the surface of the thin steel plate 5 is coated with the fabric base. This is done by bringing it into intimate contact with the inner surface of 4. Further, at the time of this pasting, by leaving a gap 6 having a height of about 1 to 3 cm at the lower part of the fabric foundation 4, corrosion due to moisture of the pasted thin steel sheet 5 is prevented.
薄鋼板５は、この図示例では、表面に５５％アルミニウム−亜鉛合金めっきを施した厚さ０．０６ｍｍの表面処理鋼板（商品名「アルジンク」）を使用しているが、これに限るものではなく、厚さ０．０２ｍｍ〜２．００ｍｍの薄鋼板であれば、他の表面処理鋼板や各種冷延鋼板（冷延ＦＨ鋼板、冷延焼鈍鋼板など）を使用することが可能である。 In this illustrated example, the thin steel plate 5 uses a surface-treated steel plate (trade name “Alzink”) having a thickness of 0.06 mm and 55% aluminum-zinc alloy plating applied thereto. If it is a thin steel plate with a thickness of 0.02 mm to 2.00 mm, other surface-treated steel plates and various cold-rolled steel plates (cold-rolled FH steel plates, cold-rolled annealed steel plates, etc.) can be used.
図３は、本発明の他の実施例であり、内面に薄鋼板５を貼り付けた布基礎４にて囲まれた土間（コンクリート間）１に、白蟻防除装置７を所要数設置した例である。 FIG. 3 shows another embodiment of the present invention, in which a required number of white ant control devices 7 are installed in the soil (between concrete) 1 surrounded by the cloth foundation 4 with the thin steel plate 5 attached to the inner surface. is there.
すなわち、白蟻防除装置７は、図４に示すように、白蟻侵入用のスリット８を備える円筒状容器９内に、白蟻が分泌するフェロモンを主成分とする白蟻誘引剤１０と、白蟻殺虫薬（例えばアジェンダＳＣ薬液）を含浸させたセルローズ系ロール紙１１とを収容してなり、白蟻誘引剤１０により誘引されて、スリット８より容器９内に侵入した白蟻が、好物であるセルローズ系ロール紙１１を食べると殺虫されるようにしたものである。 That is, as shown in FIG. 4, the white ant control device 7, as shown in FIG. 4, has a white ant attractant 10 mainly composed of a pheromone secreted by white ants, and a white ant insecticide ( Cellulose roll paper 11 impregnated with cellulose roll paper 11 impregnated with, for example, Agenda SC chemical solution) Cellulose roll paper 11, which is a favorite of white ants that are attracted by the white ant attractant 10 and enter the container 9 through the slit 8. If you eat it, it will be killed.
この実施例では、土間またはコンクリート間に侵入した白蟻は、布基礎４を這い上がる以前に、まずその大半が誘引剤に引き寄せられて白蟻防除装置内に捕獲され、殺虫される。したがって、布基礎を這い上がろうとする白蟻の数自体が著しく減少するとともに、万が一白蟻が布基礎を這い上がった場合でも、貼り付けられた薄鋼板５により滑落するから、蟻道の形成がきわめて困難となり、一層長期間に亙って布基礎上に構築された木造建築材を白蟻の被害から防御することができる。 In this embodiment, the white ants that have entered between the soil or the concrete are first attracted to the attractant and captured in the white ant control device before they are crawled up the cloth foundation 4 and are killed. Therefore, the number of white ants trying to scoop up the fabric foundation is remarkably reduced, and even if a white ant scoops up the cloth foundation, it slides down with the thin steel plate 5 attached, so that the formation of the ant path is extremely high. This makes it difficult to protect the wooden building materials built on the fabric foundation for a longer period of time from the damage of white ants.
本発明法の効果を確認するための実験を行なった。すなわち、１ｍ2の供試土間を囲む高さ５０ｃｍの布基礎をコンクリートで形成し、本発明法に従って、該布基礎の四隅コーナー部を含む内面全周に、下部１ｃｍの隙間を残して、幅２０ｃｍの帯状に切断加工した厚さ０．０６ｍｍの表面処理鋼板（５５％アルミニウム−亜鉛合金めっき鋼板）を貼り付けた。そうして、この供試土間内にイエ白蟻４００頭を放ち、木製蓋をして、１０日間内部を密閉しておいた。 An experiment for confirming the effect of the method of the present invention was conducted. That is, a 50 cm high cloth foundation surrounding 1 m 2 of the test soil is formed of concrete, and according to the method of the present invention, a gap of a lower 1 cm is left around the entire inner surface including the four corners of the cloth foundation. A surface-treated steel sheet (55% aluminum-zinc alloy plated steel sheet) having a thickness of 0.06 mm cut into a 20 cm band was attached. Then, 400 white ants were released in the test soil, covered with a wooden lid, and the inside was sealed for 10 days.
比較例として、上記同様に、１ｍ2 の供試土間を囲む高さ５０ｃｍの布基礎をコンクリートで形成し、その供試土間内にイエ白蟻４００頭を放った後、木製蓋をして、１０日間内部を密閉しておいた。 As a comparative example, similarly to the above, a 50 cm high cloth foundation surrounding 1 m 2 of test soil is formed of concrete, and 400 white ants are released in the space between the test soils, and then a wooden lid is applied. The interior was sealed for days.
その結果、本発明例では、１０日後においても、四隅のコーナー部を含めて布基礎の内面には、蟻道が全く形成されていなかった。これに対して、比較例では、１０日後において、既に布基礎の内面に幾つかの蟻道が形成されており、特に２カ所のコーナー部に形成された蟻道は、高さ５０ｃｍの布基礎を這い上がって木製蓋に到達していた。これにより、本発明法が、蟻道の形成を有効に阻止し、既設住宅等の白蟻被害を長期間防御し得ることが判明した。 As a result, in the example of the present invention, no dovetail was formed on the inner surface of the fabric foundation including the corner portions at the four corners even after 10 days. On the other hand, in the comparative example, after 10 days, several ant roads have already been formed on the inner surface of the cloth foundation, and in particular, the ant roads formed at the two corners are 50 cm high. Crawled up and reached the wooden lid. Thus, it has been found that the method of the present invention can effectively prevent the formation of ant roads and protect white ant damage on existing houses for a long period of time.
