Description

本発明は、建物用パネルの切断方法に関する。   The present invention relates to a method for cutting a building panel.

例えば鉄骨造建物の建築工事において、床や壁を構成するＡＬＣ（軽量発泡コンクリート）パネルなどの建物用パネルの一部が建物の柱などと干渉する場合、建築現場において、電動のレシプロソーなどの鋸を用いて、パネルを部分的に切断加工することが行われている。この切断加工の際に、パネルの切り粉が風に舞って飛散して、建築現場や近隣を汚すことがある。特に、高速で刃が動く電動鋸を使用する場合には、より多くの切り粉が飛散し、その対策が必要である。なお、電動丸鋸を示す文献として、特許文献１がある。   For example, when building a steel structure building, if some of the building panels such as ALC (lightweight foamed concrete) panels that make up the floor and walls interfere with the pillars of the building, use a saw such as an electric reciprocating saw at the building site. In some cases, the panel is partially cut. During this cutting process, the cutting powder on the panel may fly in the wind and scatter, contaminating the construction site and the neighborhood. In particular, when an electric saw whose blade moves at high speed is used, more swarf is scattered and countermeasures are required. In addition, there exists patent document 1 as literature which shows an electric circular saw.

このようなパネルの切り粉の飛散を抑制するため、パネルやその周囲に予め水を散布することが行われている。   In order to suppress the scattering of the swarf of such a panel, water is sprayed in advance on the panel and its surroundings.

特開平５−３１７０１号公報Japanese Patent Laid-Open No. 5-31701

しかしながら、水を散布する場合、パネル全体が濡れるので、その後乾燥に時間がかかり、その分パネルの加工及び設置作業に時間がかかる。特にＡＬＣパネルの場合は、内部に水が浸透するので、飛散防止のための水が大量に必要で、その分乾燥にも時間がかかる。さらに、散水作業を行う建築現場の床面や地面が濡れるので、養生が必要となる。   However, when water is sprayed, the entire panel gets wet, so that it takes time to dry, and accordingly, processing and installation of the panel take time. In particular, in the case of an ALC panel, since water penetrates into the inside, a large amount of water is required to prevent scattering, and it takes time to dry. Furthermore, since the floor and ground of the construction site where the watering work is carried out, curing is necessary.

本発明はかかる点に鑑みてなされたものであり、ＡＬＣパネルなどの建物用パネルやその周囲を濡らさないように、切り粉の飛散を抑制できる建物用パネルの切断方法を提供することをその目的とする。   This invention is made | formed in view of this point, The objective is to provide the cutting method of the panel for buildings which can suppress scattering of swarf so that it may not wet the panel for buildings, such as an ALC panel, and its circumference | surroundings. And

上記目的を達成するための本発明は、建物用パネルの切断予定部の表面に粘性を有する液体を塗布し、その後鋸により前記切断予定部を切断する、建物用パネルの切断方法である。   In order to achieve the above object, the present invention is a method for cutting a building panel, in which a liquid having viscosity is applied to the surface of the planned cutting portion of the building panel, and then the predetermined cutting portion is cut with a saw.

本発明によれば、パネルの切断予定部の表面に塗布された、粘性を有する液体に切り粉が吸着するので、切り粉の飛散を抑制できる。また、パネルの切断予定部にのみ、粘性を有する液体が塗布されるので、従来のようにパネル全体やその周囲が濡れることを防止できる。   According to the present invention, the swarf is adsorbed to the viscous liquid applied to the surface of the scheduled cutting portion of the panel, so that scattering of the swarf can be suppressed. Further, since the viscous liquid is applied only to the planned cutting portion of the panel, it is possible to prevent the entire panel and its surroundings from getting wet as in the prior art.

前記切断予定部の表面に加え、裏面にも前記液体を塗布するようにしてもよい。かかる場合、パネルの裏面側から切り粉が飛散することも抑制できる。   In addition to the surface of the planned cutting portion, the liquid may be applied to the back surface. In such a case, it is possible to suppress the scattering of chips from the back side of the panel.

前記鋸により前記パネルの切断予定部を切断する際に、前記パネルに切り溝を形成し、その後切断を中断し、前記切り溝に粘性を有する液体を注入し、その後切断を再開するようにしてもよい。かかる場合、粘性を有する液体に切り粉がより効果的に吸着され、切り粉の飛散をさらに抑制できる。   When cutting the scheduled cutting portion of the panel with the saw, a kerf is formed in the panel, the cutting is then interrupted, a viscous liquid is injected into the kerf, and then the cutting is resumed. Also good. In such a case, the swarf is more effectively adsorbed to the viscous liquid, and scattering of the swarf can be further suppressed.

前記切断予定部に粘性を有する液体を供給しながら、前記鋸により前記切断予定部を切断するようにしてもよい。かかる場合、粘性を有する液体に切り粉がより効果的に吸着され、切り粉の飛散をさらに抑制できる。   You may make it cut | disconnect the said cutting scheduled part with the said saw, supplying the liquid which has viscosity to the said cutting planned part. In such a case, the swarf is more effectively adsorbed to the viscous liquid, and scattering of the swarf can be further suppressed.

前記パネルは、軽量発泡コンクリートであってもよい。軽量発泡コンクリートは、切断時に切り粉が飛散しやすいものであるため、本発明のように切断予定部に粘性を有する液体を塗布する効果は大きい。   The panel may be lightweight foamed concrete. Since lightweight foamed concrete is likely to scatter dust when it is cut, the effect of applying a viscous liquid to the planned cutting portion as in the present invention is great.

本発明によれば、パネルやその周囲を極力濡らすことなく切り粉の飛散を抑制できるので、パネルを乾燥させる手間や時間が不要となり、建築現場の養生も不要となる。従って、建築コストの低減や建築工期の短縮を図ることができる。   According to the present invention, the scattering of chips can be suppressed without wetting the panel and its surroundings as much as possible. Therefore, the labor and time for drying the panel are unnecessary, and the curing of the construction site is also unnecessary. Therefore, the construction cost can be reduced and the construction period can be shortened.

以下、図面を参照して、本発明に係るパネルの切断方法の好ましい実施の形態について説明する。なお、本明細書及び図面において、実質的に同一の機能構成を有する構成要素については、同一の符号を付することにより重複説明を省略する。   A preferred embodiment of a panel cutting method according to the present invention will be described below with reference to the drawings. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

先ず、例えば図１に示すように、部分的な切断が必要な建物用パネルとしてのＡＬＣパネル１が用意される。図１に示すＡＬＣパネル１は、例えば柱と干渉する隅角部が切断されるもので、Ｌ字状の切断予定部Ａを有している。   First, as shown in FIG. 1, for example, an ALC panel 1 is prepared as a building panel that requires partial cutting. The ALC panel 1 shown in FIG. 1 has a corner portion that interferes with a pillar, for example, and has an L-shaped cutting scheduled portion A.

次に、例えば図２に示すように、粘性を有する液体１０を収容したノズル付の容器１１が用意される。液体１０には、例えば水に粘性を持たせる増粘剤を添加したもの（ジェル状のもの）が用いられる。増粘剤には、例えばキサンタンガム、グアーガム、カラギーナン、ローカストビーンガムなど水溶性の増粘剤を用いてもよく、特にキサンタンガムが望ましい。また、キサンタンガムを用いる場合は、例えば水１００ｃｃに対してキサンタンガム０．５〜１ｇ程度を添加するのが望ましい。容器１１には、例えば胴部を押して中身を吐出させるものであって、吐出口が比較的小さなノズル付のボトル（油差し、液状調味料用の容器などを転用してもよい）を用いる。   Next, for example, as shown in FIG. 2, a nozzle-equipped container 11 containing a liquid 10 having viscosity is prepared. As the liquid 10, for example, a liquid to which a thickener for imparting viscosity to water (gel-like one) is used. As the thickener, a water-soluble thickener such as xanthan gum, guar gum, carrageenan, locust bean gum may be used, and xanthan gum is particularly desirable. Moreover, when using a xanthan gum, it is desirable to add about 0.5-1 g of xanthan gum with respect to 100 cc of water, for example. For the container 11, for example, a bottle with a nozzle having a relatively small discharge port (an oil jug, a container for liquid seasoning, or the like may be used) is used to push the body part and discharge the contents.

次に、ＡＬＣパネル１を水平に寝かせた状態で、容器１１からＡＬＣパネル１の切断予定部Ａの表面に液体１０が塗布される。図３に示すように液体１０は、Ｌ字状の切断予定部Ａに沿って塗布される。   Next, in a state where the ALC panel 1 is laid down horizontally, the liquid 10 is applied from the container 11 to the surface of the planned cutting portion A of the ALC panel 1. As shown in FIG. 3, the liquid 10 is applied along the L-shaped cutting planned portion A.

その後、図４に示すようにレシプロソー、セーバーソーなどの電動鋸１２が用意され、ＡＬＣパネル１の切断予定部Ａが切断される。   After that, as shown in FIG. 4, an electric saw 12 such as a reciprocating saw or a saver saw is prepared, and the scheduled cutting portion A of the ALC panel 1 is cut.

本実施の形態によれば、ＡＬＣパネル１を切断する際に、切断予定部Ａの表面の粘性を有する液体１０に切り粉が吸着するので、切り粉の飛散が抑制される。また、ＡＬＣパネル１の切断予定部Ａにのみ液体１０が塗布されるので、従来のようにパネル全体やその周囲が濡れることを防止できる。これにより、従来のような濡れたＡＬＣパネル１を乾燥させる手間や時間が不要となり、建築現場の養生も不要となる。従って、建築コストの低減や建築工期の短縮を図ることができる。   According to the present embodiment, when the ALC panel 1 is cut, the swarf is adsorbed to the liquid 10 having the viscosity of the surface of the scheduled cutting portion A, and thus the scattering of the swarf is suppressed. In addition, since the liquid 10 is applied only to the planned cutting portion A of the ALC panel 1, it is possible to prevent the entire panel and its surroundings from getting wet as in the related art. Thereby, the trouble and time to dry the wet ALC panel 1 like the conventional one become unnecessary, and the curing of the construction site becomes unnecessary. Therefore, the construction cost can be reduced and the construction period can be shortened.

特にＡＬＣパネル１の場合、通常の建物用パネルに比べて切り粉が飛散しやすく、従来は切り粉の飛散を防止するための水の散布を大量に行う必要があり、パネルやその周囲がひどく濡れることが多かった。このため、ＡＬＣパネル１の場合、本実施の形態のように液体１０を切断予定部Ａにのみ塗布して切り粉の飛散を抑制するメリットは大きい。   In particular, in the case of the ALC panel 1, swarf is more likely to scatter than an ordinary building panel. Conventionally, it is necessary to apply a large amount of water to prevent the swarf from being scattered. I often got wet. For this reason, in the case of the ALC panel 1, the merit which suppresses scattering of a chip by apply | coating the liquid 10 only to the cutting scheduled part A like this Embodiment is large.

上記実施の形態において、図５に示すように切断予定部Ａの表面に加え、裏面にも粘性を有する液体１０を塗布するようにしてもよい。かかる場合、ＡＬＣパネル１の裏面側から切り粉が飛散することを抑制できる。   In the above embodiment, the liquid 10 having viscosity may be applied to the back surface in addition to the surface of the scheduled cutting portion A as shown in FIG. In such a case, it is possible to prevent the chips from scattering from the back side of the ALC panel 1.

また、上記実施の形態においてＡＬＣパネル１の切断の際に、粘性を有する液体１０を切断予定部Ａにさらに供給してもよい。例えば図６に示すように、電動鋸１２により切断予定部Ａの表層部に切り溝Ｂを形成し、その後電動鋸１２による切断を中断し、図７に示すように容器１１により切り溝Ｂに液体１０を注入し、その後電動鋸１２による切断を再開するようにしてもよい。かかる場合、切り粉が液体１０により効果的に吸着され、切り粉の飛散をさらに抑制できる。   In the above embodiment, when the ALC panel 1 is cut, the viscous liquid 10 may be further supplied to the planned cutting portion A. For example, as shown in FIG. 6, a cut groove B is formed in the surface layer portion of the planned cutting portion A by the electric saw 12, and then the cutting by the electric saw 12 is interrupted, and as shown in FIG. The liquid 10 may be injected, and then the cutting by the electric saw 12 may be resumed. In such a case, the chips are effectively adsorbed by the liquid 10 and the scattering of the chips can be further suppressed.

また、図８に示すように容器１１により、粘性を有する液体１０を切断予定部Ａに供給しながら、電動鋸１２により切断予定部Ａを切断するようにしてもよい。かかる場合も、切り粉が液体１０により効果的に吸着され、切り粉の飛散をさらに抑制できる。   Further, as shown in FIG. 8, the cutting portion A may be cut by the electric saw 12 while the viscous liquid 10 is supplied to the cutting portion A by the container 11. Even in such a case, the chips are effectively adsorbed by the liquid 10, and the scattering of the chips can be further suppressed.

以上、添付図面を参照しながら本発明の好適な実施の形態について説明したが、本発明はかかる例に限定されない。当業者であれば、特許請求の範囲に記載された思想の範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。   The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

例えば以上の実施の形態において、液体１０は、容器１１により切断予定部Ａに塗布されていたが、刷毛などにより塗布されてもよい。また、電動鋸１２により切断予定部Ａが切断されていたが、本発明は、手動の鋸を用いて切断予定部Ａを切断する場合にも適用できる。さらに、本発明は、ＡＬＣパネル１の隅角部以外の部分を切断する場合にも適用でき、切断予定部Ａの形も任意に選択できる。また、本発明は、ＡＬＣパネル以外の建物用パネルを切断する際にも適用できる。   For example, in the above embodiment, the liquid 10 is applied to the planned cutting portion A by the container 11, but may be applied by a brush or the like. Moreover, although the cutting scheduled part A was cut | disconnected by the electric saw 12, this invention is applicable also when cutting the cutting planned part A using a manual saw. Furthermore, the present invention can be applied to the case where a portion other than the corner portion of the ALC panel 1 is cut, and the shape of the planned cutting portion A can be arbitrarily selected. The present invention can also be applied to cutting building panels other than ALC panels.

本発明は、建物用パネルやその周囲を濡らさないように、パネル切断時の切り粉の飛散を抑制する際に有用である。   INDUSTRIAL APPLICABILITY The present invention is useful when suppressing scattering of chips when cutting a panel so as not to wet a building panel and its surroundings.
