Description
本発明は、新建築物の基礎施工時において、地中に潜む白蟻が、布基礎にて囲まれた地面上に形成される基礎コンクリート間を貫通して建物内に侵入するのを防除する方法に関する。 The present invention relates to a method for preventing white ants lurking in the ground from penetrating through the foundation concrete formed on the ground surrounded by the cloth foundation and entering the building during foundation construction of a new building. About.
家屋等の建築物を新築する場合には、その基礎施工時において、建物が地面と接するところにコンクリート造の布基礎を設ける。そして、この布基礎で囲まれた地面（土間）上に鉄筋を配置し、コンクリートを打設して基礎コンクリート間を形成するのであるが、その際、地中に潜む白蟻が、基礎コンクリート間を貫通して建物内に侵入するのを防止しておく必要がある。 When building a new building such as a house, a concrete cloth foundation is provided where the building is in contact with the ground. And, reinforcing bars are placed on the ground (between soils) surrounded by this fabric foundation, and concrete is placed to form the foundation concrete. At that time, white ants lurking in the ground move between the foundation concrete. It is necessary to prevent it from penetrating into the building.
その対策として、従来は、（１）布基礎にて囲まれた地面上に、白蟻の貫通を防止するためのビニールシートを敷き、その上に基礎コンクリート間を形成するか、あるいは（２）布基礎にて囲まれた地面上に、白蟻の貫通を防止するためのアルミ箔を敷き、その上に基礎コンクリート間を形成することが行なわれていた。 As countermeasures, conventionally, (1) a vinyl sheet for preventing the penetration of white ants is laid on the ground surrounded by the fabric foundation, and a space between the foundation concrete is formed thereon, or (2) the fabric On the ground surrounded by the foundation, an aluminum foil for preventing the penetration of white ants was laid, and a space between the foundation concrete was formed thereon.
しかしながら、上記（１）の方法では、ビニールシート自体が白蟻に喰われたり、また比較的早期に劣化して、所定の耐用年数を待たずに基礎コンクリート間に白蟻が侵入し、建物に被害を及ぼす場合が多々あった。また（２）の方法では、地面に敷設したアルミ箔が比較的長期間に亙って白蟻の侵入を防止するものの、破損し易く、施工時等において敷設されたアルミ箔上を作業員が歩いたり、配筋用の鉄筋等が触れるだけで簡単に破れてしまい、このような破損ヶ所から白蟻が基礎コンクリート間上に侵入する場合が多々あった。 However, in the method of (1) above, the vinyl sheet itself is eaten by the white ants, or deteriorates relatively early, and the white ants enter between the basic concrete without waiting for the predetermined service life, causing damage to the building. There were many cases of effects. In the method (2), although the aluminum foil laid on the ground prevents the invasion of white ants over a relatively long period of time, it is easy to break and an operator walks on the aluminum foil laid during construction. In other cases, white ants may invade between the foundation concrete from such damaged locations.
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、新建築物の基礎施工時において、布基礎にて囲まれた地面上に形成される基礎コンクリート間への白蟻の侵入を長期間防止するとともに、上記の如く形成された基礎コンクリート間に、万が一白蟻が侵入した場合には、侵入した白蟻を確実に捕獲して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. In the foundation construction of a new building, white ants are inserted between the foundation concrete formed on the ground surrounded by the cloth foundation. In addition to preventing invasion for a long time, in the unlikely event that white ants invade between the foundation concrete formed as described above, it is also intended to provide a method for reliably capturing and killing the invading white ants. .
上記目的を達成する本発明の方法は、新建築物の基礎施工時において、周囲を布基礎にて囲まれる地面上に、両面をビニールシートで被覆してなる薄鋼板を隙間なく敷設し、その上に、鉄筋を配置し又は鉄筋を配置することなくコンクリートを打設して、基礎コンクリート間を形成することを特徴とする。 The method of the present invention that achieves the above object is to lay a thin steel plate with both sides covered with a vinyl sheet on the ground surrounded by a cloth foundation without any gaps during the foundation construction of a new building, It is characterized in that concrete is placed without placing reinforcing bars or reinforcing bars to form a space between foundation concrete.
この場合、形成された基礎コンクリート間には、白蟻が万が一侵入した場合に備えて、
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, in case of white ants intruding between the formed foundation concrete,
It is necessary to install the required number of white ant control devices that contain white ant attractant and cellulose roll paper impregnated with insecticide that becomes white ant bait in a container equipped with slits for invading white ants. good.
また、本発明法で使用する薄鋼板としては、厚さ０．０２ｍｍ〜２．００ｍｍ程度の表面処理鋼板又は冷延鋼板が望ましい。厚さ０．０２ｍｍ以下では、長期（３年以上）の耐腐蝕性が得られず、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程度の「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、冷延焼鈍鋼板等）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、最も使い易く、推奨される。 Moreover, as a thin steel plate used by this invention method, the surface-treated steel plate or cold-rolled steel plate about 0.02 mm-2.00 mm in thickness is desirable. If the thickness is 0.02 mm or less, long-term (3 years or more) corrosion resistance cannot be obtained, and if it is 2.00 mm or more, workability and handling properties at the time of construction deteriorate, making construction work difficult. is there. In particular, surface-treated steel sheets and cold-rolled steel sheets (such as cold-rolled FH steel sheets and cold-rolled annealed steel sheets) called “Alzinc” with a thickness of about 0.06 mm are excellent in workability such as bending during construction and cutting by iron pinching. Moreover, it has the strength that does not break easily like an aluminum foil even when an operator walks on it, so it is the easiest to use and recommended.
上記構成よりなる本発明の方法によれば、周囲を布基礎に囲まれた地中に潜む白蟻は、その地面上に敷設された薄鋼板を食い切って貫通することができず、また、これらの薄鋼板自体が折り曲げ可能な可撓性を有し容易に破損を生じることも無いので、さらにその上に形成される基礎コンクリート間にほとんど侵入することができない。また、これらの薄鋼板は、水分を含む地面やコンクリートと直接触れないように、その両面がビニールシートで被覆してあるから耐腐蝕性に優れ、かつ、床下土壌からの湿気を防ぎ床下空間を乾燥した状態に保持する効果を有する。したがって、新建築物を長期間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 white ants lurking in the ground surrounded by the cloth foundation cannot penetrate through the thin steel plate laid on the ground, and these Since the thin steel plate itself is foldable and does not easily break, it can hardly penetrate between the basic concrete formed thereon. These steel sheets are not directly touch the ground or concrete containing water, excellent corrosion resistance because its both surfaces are coated with a vinyl sheet, and the underfloor space prevents moisture from under the floor soil It has the effect of keeping it dry. Therefore, the new building can be protected from the damage of white ants over a long period of time.
さらに、上記本発明法により形成される基礎コンクリート間に、白蟻防除装置を設置した場合には、当該基礎コンクリート間に侵入した白蟻が、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、捕獲された白蟻が餌であるロール紙を食べることにより殺虫される。したがって、万が一、基礎コンクリート間に白蟻が侵入した場合でも、侵入した白蟻はほぼ確実に捕獲され、殺虫されるから、一層確実に、新築建物を長期間に亙って白蟻の被害から防御することができる。 Further, when a white ant control device is installed between the basic concrete formed by the method of the present invention, the white ants that have entered between the basic concrete are attracted to the attractant and captured in the white ant control device, and The captured white ants are killed by eating the roll paper that is the bait. Therefore, in the unlikely event that a white ant enters between the foundation concrete, the invaded white ant is almost certainly captured and killed, so that the new building can be protected over a long period of time from white ant damage. Can do.
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、本発明の方法を、新築建物の基礎施工に実施した一例であり、１はコンクリート造の布基礎、４は薄鋼板、６は基礎コンクリート間を示している。 1 and 2 show an example in which the method of the present invention is applied to the foundation construction of a new building, where 1 is a concrete cloth foundation, 4 is a thin steel plate, and 6 is between the foundation concrete.
すなわち、布基礎１は、建物の外周壁や主要な間仕切り壁等の地面２と接するところに構築されるコンクリート造の台であり、この上に木造の土台３が築かれる。 That is, the fabric foundation 1 is a concrete base constructed in contact with the ground 2 such as an outer peripheral wall of a building or a main partition wall, and a wooden base 3 is built thereon.
薄鋼板４は、周囲を上記布基礎１にて囲まれる地面２上に、その両面をビニールシート５ａ，５ｂで被覆した状態で隙間なく敷設してある。すなわち、図示例では、布基礎１で囲まれる地面２上に、まずビニールシート５ａを敷き、その上に薄鋼板４を敷く。このとき、薄鋼板４は、図３に示すように、上記地面２の広さや形状に応じて複数枚を組み合わせたり、また所要の形状に鉄挟みで裁断したものを使用して、ビニールシート５ａ上に隙間なく敷き詰められる。次いで、上記の如く敷き詰めた薄鋼板４上に、別のビニールシート５ｂを敷く。このようにして、両面がビニールシート５ａ，５ｂで被覆された状態の薄鋼板４が、周囲を布基礎１にて囲まれる地面２上に隙間なく敷設されている。 The thin steel plate 4 is laid without gaps on the ground 2 surrounded by the cloth foundation 1 with both surfaces covered with vinyl sheets 5a and 5b. That is, in the illustrated example, a vinyl sheet 5a is first laid on the ground 2 surrounded by the cloth foundation 1, and a thin steel plate 4 is laid thereon. At this time, as shown in FIG. 3, the thin steel plate 4 is a combination of a plurality of sheets according to the width and shape of the ground 2, or a sheet that is cut into a required shape with an iron pin, and is used as a vinyl sheet 5 a. It can be laid on top without any gaps. Next, another vinyl sheet 5b is laid on the thin steel plate 4 spread as described above. In this way, the thin steel plate 4 whose both surfaces are covered with the vinyl sheets 5a and 5b is laid on the ground 2 surrounded by the cloth foundation 1 without any gaps.
この図示例では、薄鋼板４として、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程度の薄鋼板であれば、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。なお、これらの被覆用ビニールシート５ａ，５ｂは、いずれも厚さ０．０４ｍｍ程度の通常のビニールシートである。 In this illustrated example, a surface-treated steel sheet (trade name “Alzinc”) having a thickness of 0.06 mm and 55% aluminum-zinc alloy plating is used as the thin steel sheet 4, but is not limited to this. However, if it is a thin steel plate having a thickness of about 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 . Na us, these coating vinyl sheets 5a, 5b are both normal vinyl sheet having a thickness of about 0.04 mm.
基礎コンクリート間６は、上記の如く周囲を布基礎１にて囲まれた地面２上に、両面をビニールシート５ａ，５ｂで被覆した状態の薄鋼板４を隙間なく敷設し、さらにその上に、所要数の鉄筋材７を配置するか、または鉄筋材７を全く配置することなくコンクリートを所要厚さに打設することにより形成されたコンクリート造の土間である。 Between the basic concrete 6, as described above, on the ground 2 surrounded by the cloth foundation 1, the thin steel plate 4 having both surfaces covered with the vinyl sheets 5 a and 5 b is laid without gaps, and further, A concrete soil is formed by placing a required number of reinforcing bars 7 or placing concrete to a required thickness without arranging reinforcing bars 7 at all.
図４は、本発明の他の実施例であり、前記実施例１により形成された基礎コンクリート間６に、白蟻防除装置８を所要数配置した例である。 FIG. 4 shows another embodiment of the present invention, in which a required number of white ant control devices 8 are arranged between the foundation concrete 6 formed according to the first embodiment.
すなわち、白蟻防除装置８は、図５に示すように、白蟻侵入用のスリット９を備える円筒状容器１０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１１と、白蟻殺虫薬（例えばアジェンダＳＣ）を含浸させたセルローズ系ロール紙１２とを収容してなり、白蟻誘引剤１１により誘引されて、スリット９より容器１０内に侵入した白蟻が、好物であるセルローズ系ロール紙１２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. 5, the white ant control apparatus 8 includes a white ant attractant 11 mainly composed of a pheromone secreted by white ants and a white ant insecticide ( Cellulose roll paper 12 impregnated with, for example, Agenda SC) is accommodated, and white ants that are attracted by the white ant attractant 11 and enter the container 10 through the slits 9 are the favorite cellulose roll paper 12. It is designed to kill insects when eaten.
したがって、この実施例では、実施例１の方法により白蟻の侵入がきわめて困難となった新建築物のコンクリート間６に、万が一、白蟻が侵入した場合でも、これを白蟻防除装置８が確実に捕獲して殺虫するから、新建築物をさらに長期間に亙って白蟻の被害から防御することができる。 Therefore, in this embodiment, even if a white ant has intruded into the concrete space 6 of the new building where the entry of the white ant has become extremely difficult by the method of the first embodiment, the white ant control device 8 surely captures this. Because it kills insects, it can protect the new building from the damage of white ants over a longer period of time.
表１は、本発明法の実施により形成された基礎コンクリート間上への白蟻の侵入数を、５年間に亙って調査し、その結果を比較例とともに示したものである。 すなわち、Ａは、周囲を布基礎で囲んだ３ｍ2の供試地面に、本発明法にしたがって両面をビニールシートで被覆した薄鋼板（厚さ０．０６ｍｍのアルジンク表面処理鋼板）を敷き、その上に基礎コンクリート間を形成した本発明例。Ｂは、上記同様の供試地面に、アルミ箔（厚さ０．０６ｍｍ）を敷き、その上に基礎コンクリート間を形成した比較例。同じくＣは、上記同様の供試地面に、ビニールシート（厚さ０．０４ｍｍ）を敷き、その上に基礎コンクリート間を形成した比較例である。なお、白蟻の侵入数は、各例ともに、供試地面上に形成された基礎コンクリート間の中央部に、白蟻誘引剤と白蟻殺虫薬を含浸したセルローズ系ロール紙を収容してなる白蟻防除装置を設置し、この白蟻防除装置に捕獲され、殺虫された白蟻数を示している。 Table 1 shows the number of white ants invading between the foundation concretes formed by the implementation of the method of the present invention over 5 years, and shows the results together with comparative examples. That is, A spreads a thin steel plate (alzinc surface-treated steel plate having a thickness of 0.06 mm) coated on both sides with a vinyl sheet according to the method of the present invention on a 3 m 2 test ground surrounded by a cloth foundation. The example of this invention which formed between the basic concrete on. B is a comparative example in which an aluminum foil (thickness: 0.06 mm) is laid on the test ground similar to the above, and a base concrete is formed thereon. Similarly, C is a comparative example in which a vinyl sheet (thickness: 0.04 mm) is laid on the same test ground as described above and a space between the foundation concrete is formed thereon. The number of invaders of white ants is the white ant control device in which cellulosic roll paper impregnated with white ant attractant and white ant pesticide is housed in the center between the foundation concrete formed on the test ground in each example. The number of white ants captured and killed by this white ant control device is shown.
表１に明らかなとおり、本発明例Ａは、基礎コンクリート間を形成後、５年を経過してもなを、基礎コンクリート上への白蟻の侵入数は０であるのに対して、比較例Ｂは、６カ月後に侵入数５３、１年後には４５５となり、短期間で著しく増加していた。また、比較例Ｃは、１年後に侵入数が７１となり、以後、２年目で３７７、３年目で５１３と、年々増加していた。これにより、本発明法が、従来法に比べて、はるかに長期間の基礎コンクリート間上への白蟻の侵入防止効果に優れていることが判明した。 As is apparent from Table 1, Example A of the present invention is a comparative example in which the number of white ants entering the basic concrete is 0, even though 5 years have passed since the formation between the basic concrete. B had 53 intrusions after 6 months and 455 after 1 year, and increased significantly in a short period of time. Further, in Comparative Example C, the number of intrusions became 71 after one year, and thereafter increased year by year to 377 in the second year and 513 in the third year. As a result, it was found that the method of the present invention is superior in the effect of preventing white ants from entering between the basic concrete for a much longer period of time than the conventional method.
