Description

本発明は、建築分野に使用されるＡＬＣパネルなどの脆性材パネルの縁辺部に帯状の切削部を形成する脆性材切削治具に関する。   The present invention relates to a brittle material cutting jig for forming a band-shaped cutting portion at an edge portion of a brittle material panel such as an ALC panel used in the construction field.

ＡＬＣ（オートクレーブ発泡コンクリート）は、軽量で耐火性、耐熱性及び施工性に優れているために、パネルに成形されて建築分野で広く使用されている。この場合、ＡＬＣパネルの鉄骨建築物への取り付けに際しては建築物の鉄骨梁に固着した定規アングルに取り付けた金具にボルト止めし、木造建築物への取り付けに際しては、柱、間柱或いは胴縁に所定の金具やビスによって固定することが行われている。
この取り付けにおいては、鉄骨建築物の場合はフランジ、定規アングル、ボルトなどが、木造建築物の場合はサッシ、水切りなどが付帯物として存在するので、これらの付帯物の一部が、ＡＬＣパネル面から突出しないように埋設することが必要になる。このために、ＡＬＣパネルの周辺部を、鋸刃などを用いて切削することが行なわれている。 ALC (autoclave foamed concrete) is lightweight and excellent in fire resistance, heat resistance and workability, and thus is formed into a panel and widely used in the construction field. In this case, when attaching the ALC panel to a steel building, it is bolted to a metal fitting attached to a ruler angle fixed to the steel beam of the building. Fixing with metal fittings and screws.
In this installation, flanges, ruler angles, bolts, etc. exist for steel buildings, and sashes, drainers, etc., exist as appendages for wooden buildings. It is necessary to bury it so that it does not protrude from. For this purpose, the peripheral part of the ALC panel is cut using a saw blade or the like.

しかし、この従来の切削法では、ＡＬＣパネルに対して欠落部なく且つ高仕上げ精度で加工するためには熟練作業が必要で、作業性も悪かった。
この問題を解決するために、後記する特許文献１には、定規アングルに固定された取付金具などが、パネル面から突出しないように埋設する小口切り欠きを、ＡＬＣパネルの縁辺部からパネル内側に熟練作業を要せずに短時間で形成するＡＬＣパネル切り欠き加工かんなが開示されている。 However, with this conventional cutting method, skillful work is required to process the ALC panel with no missing part and high finishing accuracy, and workability is also poor.
In order to solve this problem, Japanese Patent Application Laid-Open No. H10-228667, which will be described later, has a small notch that is embedded in a mounting angle fixed to a ruler angle so as not to protrude from the panel surface from the edge of the ALC panel to the inside of the panel. An ALC panel cutout planer that can be formed in a short time without requiring work is disclosed.

ところで、木造住宅においては、サッシの周囲に配置されるＡＬＣパネルの縁辺をＬ字状に切断し、このＡＬＣパネルをサッシの周囲に取り付けることが行なわれており、この場合に、サッシとの干渉を防止するために、ＡＬＣパネルの縁辺部を、所定深さで帯状に切削することが必要になる。
しかし、特許文献１に記載の方法では、小口切り欠きをＡＬＣパネルの縁辺部からパネル内側方向に形成することはできるが、ガイド手段がないために、ＡＬＣパネルの縁辺部を帯状に切削するには高度の熟練を要し実際の作業に困難である。さらに、縁辺がＬ字状に切断されたＡＬＣパネルの縁辺部を帯状に切削するには、治具の当接方向を変更しての作業を、不自然な姿勢で行なわねばならず、作業は殆ど不可能と言ってもよい。 By the way, in the wooden house, the edge of the ALC panel arranged around the sash is cut into an L shape, and this ALC panel is attached around the sash. In this case, interference with the sash is performed. In order to prevent this, it is necessary to cut the edge of the ALC panel into a strip shape with a predetermined depth.
However, in the method described in Patent Document 1, a small notch can be formed from the edge of the ALC panel toward the inside of the panel, but since there is no guide means, the edge of the ALC panel is cut into a strip shape. It requires a high level of skill and is difficult for actual work. Furthermore, in order to cut the edge of the ALC panel whose edge has been cut into an L shape into a strip shape, the work of changing the contact direction of the jig must be performed in an unnatural posture. It can be said that it is almost impossible.

なお、特許文献２に開示されている脆性材料に対する溝堀用工具は、一端に握り部が形成された胴の他端部が、握り部方向にＵ字型に屈曲され、屈曲部の先端に刃が形成されたもので、脆性材料に電気配線用の溝を形成するもので、本願発明に利用される基礎技術が開示されている参考文献である。
特開平８−３００３０９号公報 特許第３４５９６７８号公報 In addition, the trench tool for the brittle material disclosed in Patent Document 2 has the other end portion of the barrel having a grip portion formed at one end bent in a U-shape in the grip portion direction, and at the tip of the bent portion. This is a reference in which a blade is formed, a groove for electric wiring is formed in a brittle material, and a basic technique used in the present invention is disclosed.
JP-A-8-300309 Japanese Patent No. 3457678

And a stopper body that slides along a side surface of the brittle material panel during the cutting operation and sets an end position of the cutting. The distance between the end faces of the stopper body facing the tip of the cutting blade or the second cutting blade At least one of, and is characterized in that it is selected and set to more than the blade width of the first cutting edge and the second cutting edge.

第１の発明では、支持体の長手両方向に、第１切削刃が固定される第１傾斜面と、第２切削刃が固定される第２傾斜面とがそれぞれ延長配設され、支持体に一体に設けられた取付台に、固定手段によって、第１切削刃が第１傾斜面に、第２切削刃が第２傾斜面にそれぞれ固定された状態で、支持体によって脆性材パネルの面上に安定に対接配置され、さらに支持体の長手方向の一側縁部が一体に屈曲延長形成されたストッパー体を、脆性材パネルの側面に沿って安定に摺動させることにより、切削の端部位置が精度よく設定された状態で、脆性材パネルの縁辺部に高品質の帯状切削部が形成される。
この場合、第１切削刃または第２切削刃の先端と対向するストッパー体の端面間距離の少なくとも一方が、第１切削刃及び第２切削刃の刃幅以上に選択設定されているので、縁辺がほぼＬ字状に切断された脆性材パネルに対して、Ｌ字屈曲部に達するまでの第１の側面の切削を一方向に行い、次いで脆性材パネルの第１の側面にほぼ直交する第２の側面に対して、往復切削を施す簡単な作業によって、建築物への取付付帯物のパネル面からの突出の原因となる非切削部を残さずに、脆性材パネルの縁辺部に所定深さで連続して高品質の帯状切削部が、加工割れのない高精度加工により切削形成される。 In the first invention, the first inclined surface to which the first cutting blade is fixed and the second inclined surface to which the second cutting blade is fixed are extended and disposed in both longitudinal directions of the support, respectively.

The end of the cutting is stably slid along the side surface of the brittle panel, with a stopper body that is stably disposed in contact with each other and further bent and extended at one side edge in the longitudinal direction of the support body. A high-quality strip-shaped cut portion is formed on the edge portion of the brittle material panel with the position of the portion set accurately.
In this case, since at least one of the distances between the end faces of the stopper body facing the tip of the first cutting blade or the second cutting blade is selected and set to be equal to or greater than the blade width of the first cutting blade and the second cutting blade, Is cut in one direction with respect to the brittle material panel cut in a substantially L shape in one direction, and then the first side surface that is substantially orthogonal to the first side surface of the brittle material panel. 2 by a simple operation of reciprocating cutting, without leaving a non-cutting portion that causes protrusion of the attachment attached to the building from the panel surface, a predetermined depth in the edge portion of the brittle material panel. The high-quality strip-shaped cutting portion is continuously formed by high-precision processing without processing cracks.

同様に前記目的を達成するために、請求項２記載の発明は、第１の発明に対して、固定手段による第１切削刃の第１傾斜面への固定、及び第２切削刃の第２傾斜面への固定時に、帯状切削部の切削深さに応じて前記固定手段の固定位置を変更する位置変更手段がさらに設けられていることを特徴とするものである。   Similarly, in order to achieve the object, the invention according to claim 2 is the first invention, wherein the first cutting blade is fixed to the first inclined surface by the fixing means, and the second cutting blade is second. Position fixing means for changing the fixing position of the fixing means in accordance with the cutting depth of the strip-shaped cutting portion at the time of fixing to the inclined surface is further provided.

第２の発明によると、第１の発明での作用に加えて、固定手段による第１切削刃の第１傾斜面への固定、及び第２切削刃の第２傾斜面への固定時に、位置変更手段によって、脆性材パネルの建築物への取付付帯物に応じて設定される帯状切削部の切削深さの設定が、固定手段による第１の切削刃及び第２の切削刃の固定と同時に簡単に行なわれる。   According to the second invention, in addition to the action in the first invention, the position of the first cutting blade is fixed to the first inclined surface by the fixing means and the second cutting blade is fixed to the second inclined surface. The setting of the cutting depth of the band-shaped cutting portion set according to the attachment attached to the building of the brittle material panel by the changing means is performed simultaneously with the fixing of the first cutting blade and the second cutting blade by the fixing means. Easy to do.

第１の発明によると、支持体の長手両方向に、第１切削刃が固定される第１傾斜面と、第２切削刃が固定される第２傾斜面とがそれぞれ延長配設され、支持体に一体に設けられた取付台に、固定手段によって、第１切削刃が第１傾斜面に、第２切削刃が第２傾斜面にそれぞれ固定された状態で、脆性材切削治具を支持体によって脆性材パネルの面上に押圧して安定に対接配置させることが可能で、さらに支持体の長手方向の一側縁部が一体に屈曲延長形成されたストッパー体を、脆性材パネルの側面に沿って安定に摺動させることにより、切削の端部位置を精度よく設定することが可能になり、脆性材パネルの縁辺部に、加工割れのない高精度加工により高品質の帯状切削部を形成することが可能になる。
この場合、第１切削刃または第２切削刃の先端と対向するストッパー体の端面間距離の少なくとも一方が、第１切削刃及び第２切削刃の刃幅以上に選択設定されているので、縁辺がほぼＬ字状に切断された脆性材パネルに対して、Ｌ字屈曲部に達するまでの第１の側面の切削を一方向に行い、次いで脆性材パネルの第１の側面にほぼ直交する第２の側面に対して、往復切削を施す簡単な作業によって、建築物への取付付帯物のパネル面からの突出の原因となる非切削部を残すことなく、脆性材パネルの縁辺部に所定深さで連続した高品質の帯状切削部が、加工割れのない高精度加工により切削形成され、取付付帯物のパネル面からの突出を完全に防止し、意匠性を高めることが可能になる。 According to the first invention, the first inclined surface to which the first cutting blade is fixed and the second inclined surface to which the second cutting blade is fixed are extended and arranged in both longitudinal directions of the support, respectively. In the state in which the first cutting blade is fixed to the first inclined surface and the second cutting blade is fixed to the second inclined surface by the fixing means, the brittle material cutting jig is supported on the mounting base provided integrally with the support. The stopper body, which is pressed against the surface of the brittle material panel and can be stably placed in contact with each other, and further has one side edge portion in the longitudinal direction of the support body integrally bent and extended, is provided on the side surface of the brittle material panel. It is possible to set the end position of the cutting with high accuracy by sliding it along the edge of the high-quality band-shaped cutting part by high-precision processing without processing cracks at the edge of the brittle panel. It becomes possible to form.
In this case, since at least one of the distances between the end faces of the stopper body facing the tip of the first cutting blade or the second cutting blade is selected and set to be equal to or greater than the blade width of the first cutting blade and the second cutting blade, Is cut in one direction with respect to the brittle material panel cut in a substantially L shape in one direction, and then the first side surface that is substantially orthogonal to the first side surface of the brittle material panel. 2 by a simple operation of reciprocating cutting, without leaving a non-cutting portion that causes the attachment of the attachment to the building from the panel surface, leaving a predetermined depth at the edge of the brittle panel. The continuous high-quality strip-shaped cutting portion is cut and formed by high-precision machining without processing cracks, so that the protrusion of the attachment band from the panel surface can be completely prevented, and the design can be improved.

第２の発明によると、第１の発明で得られる効果に加えて、固定手段による第１切削刃の第１傾斜面への固定、及び第２切削刃の第２傾斜面への固定時に、位置変更手段によって、脆性材パネルの建築物への取付付帯物に応じた帯状切削部の切削深さの設定を、固定手段による第１の切削刃及び第２の切削刃の固定位置の変更により簡単に行なうことが可能になる。   According to the second invention, in addition to the effects obtained in the first invention, when fixing the first cutting blade to the first inclined surface by the fixing means and fixing the second cutting blade to the second inclined surface, By setting the cutting depth of the band-shaped cutting portion according to the attachment attached to the building of the brittle material panel by the position changing means, by changing the fixing positions of the first cutting blade and the second cutting blade by the fixing means It can be done easily.

以下に、本発明の一実施の形態を、図１ないし図３を参照し、建築壁に使用されるＡＬＣパネルの縁辺部に帯状切削部を切削形成する場合について説明する。
図１は本実施の形態の構成を示す斜視図、図２は本実施の形態の構成を示す各座標軸方向での正視図、図３は本実施の形態の切削動作を示す説明図である。 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3 in which a band-shaped cutting portion is formed by cutting on an edge portion of an ALC panel used for a building wall.
FIG. 1 is a perspective view showing the configuration of the present embodiment, FIG. 2 is a front view in the direction of each coordinate axis showing the configuration of the present embodiment, and FIG. 3 is an explanatory view showing the cutting operation of the present embodiment.

本実施の形態においては、図１及び図２に示すように、切削対象となるＡＬＣパネルの板面に対接配置され、切削動作時に脆性材切削治具１２全体を、ＡＬＣパネルに対し支持する鉄材でほぼＥ字状に形成された支持体１が設けられ、この支持体１の切欠部１３ａ、１３ｂ間の板面には、ほぼアーク形状の刃取付台５が溶接固定されている。
図１に示すように、支持体１にはその長手両方向に、支持体１の板面に対して傾斜角αで、傾斜面１６ａ、１６ｂがそれぞれ形成された刃取付台５が固定され、本実施の形態では、傾斜面１６ａ、１６ｂの傾斜角αはほぼ４５°に設定されている。また、支持体１の板面の長手方向の一縁辺が、支持体１の板面に直角に屈曲延長されて、切削動作時にＡＬＣパネルの側面に対接摺動し、切削の端部位置を設定するストッパー体２が形成されている。 In this embodiment, as shown in FIG. 1 and FIG. 2, the entire brittle material cutting jig 12 is supported on the ALC panel by being disposed in contact with the plate surface of the ALC panel to be cut. A support 1 made of an iron material and having a substantially E shape is provided, and a substantially arc-shaped blade mounting base 5 is welded and fixed to a plate surface between the notches 13a and 13b of the support 1.
As shown in FIG. 1, a blade mounting base 5 having inclined surfaces 16 a and 16 b formed at an inclination angle α with respect to the plate surface of the support 1 in both longitudinal directions is fixed to the support 1. In the embodiment, the inclination angle α of the inclined surfaces 16a and 16b is set to approximately 45 °. Also, one edge in the longitudinal direction of the plate surface of the support 1 is bent and extended at a right angle to the plate surface of the support 1 so as to slide against the side surface of the ALC panel during the cutting operation, and the end position of the cutting is determined. A stopper body 2 to be set is formed.

一方、刃取付台５の傾斜面１６ａ、１６ｂにそれぞれ取り付けられる刃幅がａの切削刃３ａ、３ｂには、図２（ｂ）に示すように、中心線上に所定の調整長の長孔１５ａ、１５ｂが形成されており、切削刃３ａ、３ｂは、それぞれ長孔１５ａ、１５ｂ内で固定位置が選択され、選択された固定位置において、螺子６ａとナット１４ａによる螺合、或いは螺子６ｂとナット１４ｂによる螺合によって、それぞれ傾斜面１６ａ、或いは傾斜面１６ｂに固定されている。この固定位置の選択によって、切削刃３ａ、３ｂ先端の支持体１の裏面からの突出長が、切削形成される帯状切削部の切削深さに対応して設定される。   On the other hand, as shown in FIG. 2 (b), a long hole 15a having a predetermined adjustment length on the center line is provided on the cutting blades 3a and 3b having a blade width a attached to the inclined surfaces 16a and 16b of the blade mounting base 5, respectively. 15b are formed, and the cutting blades 3a and 3b are fixed at positions in the long holes 15a and 15b, respectively, and screwed by the screw 6a and the nut 14a at the selected fixed position, or the screw 6b and the nut. It is being fixed to the inclined surface 16a or the inclined surface 16b by the screwing by 14b, respectively. By the selection of this fixed position, the protruding length of the cutting blades 3a and 3b from the back surface of the support 1 is set in accordance with the cutting depth of the band-shaped cutting portion to be cut and formed.

この場合、本実施の形態では、図１及び図４（ａ）に示すように、傾斜面１６ａに対する切削刃３ａの位置設定によって、切削刃３ａの先端と対向するストッパー体２の端面間距離は、切削刃ａ、ｂの刃幅ａに設定され、傾斜面１６ｂに対する切削刃３ｂの位置設定によって、切削刃３ｂの先端と対向するストッパー体２の端面間距離は、切削刃ａ、ｂの刃幅ａよりも短い距離ｂ（ｂ＜ａ）に設定されるように構成されている。   In this case, in this embodiment, as shown in FIG. 1 and FIG. 4A, the distance between the end faces of the stopper body 2 facing the tip of the cutting blade 3a is set by the position setting of the cutting blade 3a with respect to the inclined surface 16a. The distance between the end faces of the stopper body 2 which is set to the blade width a of the cutting blades a and b and faces the tip of the cutting blade 3b by setting the position of the cutting blade 3b with respect to the inclined surface 16b is the blade of the cutting blades a and b. The distance b is shorter than the width a (b <a).

次に、このような構成の本実施の形態による切削動作を、ＡＬＣパネルに対して、サッシなどを取り付ける際の取付付帯物と干渉する面にＬ字状の帯状切削部を形成する場合を取り上げて説明する。
本実施の形態では、図３（ａ）に示すように、縁辺がＬ字状に切断されたＡＬＣパネル７が切削の対象となるが、切削動作時には、すでに説明したように、ＡＬＣパネル７の縁辺部に切削形成する帯状切削部の切削深さが例えば８ｍｍに設定され、この設定によって切削刃３ａの先端と対向するストッパー体２の端面間距離は刃幅ａに設定され、切削刃３ｂの先端と対向するストッパー体２の端面間距離は、刃幅ａよりも短い距離ｂに設定される。 Next, the cutting operation according to the present embodiment having such a configuration will be described in the case where an L-shaped band-shaped cutting portion is formed on a surface that interferes with an attachment attached when attaching a sash or the like to an ALC panel. I will explain.
In the present embodiment, as shown in FIG. 3A, the ALC panel 7 whose edge is cut into an L-shape is the object of cutting, but during the cutting operation, as already described, the ALC panel 7 The cutting depth of the band-shaped cutting portion formed by cutting at the edge portion is set to 8 mm, for example, and by this setting, the distance between the end faces of the stopper body 2 facing the tip of the cutting blade 3a is set to the blade width a, and the cutting blade 3b The distance between the end faces of the stopper body 2 facing the tip is set to a distance b shorter than the blade width a.

このように切削深さが設定された脆性材切削治具１２を、図３（ｂ）に示すように、ＡＬＣパネル７の縁辺部に、支持体１をＡＬＣパネル７の板面に押圧対接させ、ストッパー体２をＡＬＣパネル７の側面に安定に対接させて配置し、支持体１を押し付けながら矢印Ａ方向に移動させることにより、切削刃３ｂによってＡＬＣパネル７の縁辺部を設定した深さで切削して行く。
前述したように、切削刃３ｂの先端と対向するストッパー体２の端面間距離は、刃幅ａよりも短い距離ｂに設定されているので、この切削によって、ＡＬＣパネル７の縁辺部には、図３（ｃ）に示す帯状切削部８ａが形成される。
この切削動作は、ストッパー体２の端面が、ストッパー体２が摺動するＡＬＣパネル７の側面と、Ｌ字屈曲部において直交するＡＬＣパネル７の側面に当接する位置で停止するので、帯状切削部８ａの端部は、前述した直交する側面から微小距離ｂだけＡＬＣパネル７の内部に入り込んでいる。 As shown in FIG. 3B, the brittle material cutting jig 12 with the cutting depth set in this way is pressed against the edge of the ALC panel 7 and the support 1 is pressed against the plate surface of the ALC panel 7. The stopper body 2 is placed in a stable contact with the side surface of the ALC panel 7 and moved in the direction of arrow A while pressing the support body 1, so that the edge of the ALC panel 7 is set by the cutting blade 3 b. Now cut it.
As described above, since the distance between the end faces of the stopper body 2 facing the tip of the cutting blade 3b is set to a distance b shorter than the blade width a, by this cutting, the edge of the ALC panel 7 A band-shaped cutting portion 8a shown in FIG. 3C is formed.
This cutting operation stops at the position where the end surface of the stopper body 2 comes into contact with the side surface of the ALC panel 7 on which the stopper body 2 slides and the side surface of the ALC panel 7 orthogonal to the L-shaped bent portion. The end of 8a enters the inside of the ALC panel 7 by a minute distance b from the aforementioned orthogonal side surface.

次いで、図３（ｄ）に示すように、帯状切削部８ａに直角なＡＬＣパネル７の縁辺部に脆性材切削治具１２を配置し、脆性材切削治具１２を矢印Ｂ方向に移動させることにより、切削刃３ｂでＡＬＣパネル７の縁辺部を切削すると、同図（ｅ）に示すように、帯状切削部８ｂが形成される。この切削で形成される帯状切削部８ｂには、脆性材切削治具１２の切削刃３ａ側に非切削部１０が残存するので、次に同図（ｆ）に示すように、脆性材切削治具１２を矢印Ｃ方向に移動させ、切削刃３ａによってＡＬＣパネル７の縁辺部の切削を行なう。
切削刃３ａの先端と対向するストッパー体２の端面間距離は、刃幅ａに設定されているので、この切削では 切削刃３ａの先端と対向するストッパー体２の端面が、帯状切削部 ８ｂと直角なＡＬＣパネル７の側面と当接する位置で切削は終了し、帯状切削部８ｂに連続して、ストッパー体２が当接する側面より、刃幅ａだけＡＬＣパネル７内部に入り込んだ位置に帯状切削部８ｂの端面が設定される。
このようにして、本実施の形態によると、図３（ｇ）に示すように、縁辺がＬ字状に切断されたＡＬＣパネル７の縁辺部に、非切削部１０を残さずに、加工割れのない高精度加工により、一定幅で連続した高品質のＬ字状の帯状切削部８Ｌが、簡単な作業で形成される。 Next, as shown in FIG. 3D, the brittle material cutting jig 12 is arranged on the edge of the ALC panel 7 perpendicular to the strip-shaped cutting portion 8a, and the brittle material cutting jig 12 is moved in the direction of arrow B. Thus, when the edge portion of the ALC panel 7 is cut with the cutting blade 3b, a strip-shaped cutting portion 8b is formed as shown in FIG. Since the non-cutting portion 10 remains on the cutting blade 3a side of the brittle material cutting jig 12 in the strip-shaped cutting portion 8b formed by this cutting, as shown in FIG. The tool 12 is moved in the direction of arrow C, and the edge of the ALC panel 7 is cut by the cutting blade 3a.
Since the distance between the end faces of the stopper body 2 facing the tip of the cutting blade 3a is set to the blade width a, in this cutting, the end face of the stopper body 2 facing the tip of the cutting blade 3a is connected to the strip-shaped cutting portion 8b. Cutting ends at a position where it contacts the side surface of the ALC panel 7 at a right angle, and strip-shaped cutting is performed at a position where the blade width a enters the inside of the ALC panel 7 from the side surface where the stopper body 2 contacts, continuously from the band-shaped cutting portion 8b. The end face of the part 8b is set.
In this way, according to the present embodiment, as shown in FIG. 3G, the processing cracks are left without leaving the non-cutting portion 10 on the edge portion of the ALC panel 7 whose edge is cut into an L shape. By the high-precision machining without any, a high-quality L-shaped strip-shaped cutting portion 8L continuous with a constant width is formed by a simple operation.

以上に説明したように本実施の形態では、縁辺がほぼＬ字状に切断されたＡＬＣパネル７の縁辺部に支持体１をパネル面に押圧対接させ、ストッパー体２をパネル側面に安定に対接させて脆性材切削治具１２を、ＡＬＣパネル７の面上に安定に配置し、支持体１を押し付けながら治具を矢印Ａ方向に移動させることにより、ＡＬＣパネル７の縁辺部に切削刃３ｂで帯状切削部８ａを形成する。次いで、帯状切削部８ａに直角なＡＬＣパネル７の縁辺部に治具を移動配置して矢印Ｂ方向に移動させ、切削刃３ｂでＡＬＣパネル７の縁辺部に帯状切削部８ｂを形成した後に、同治具を矢印Ｂと逆方向に移動させて、切削刃３ａにより切削を行なう簡単な作業により、ＡＬＣパネル７の縁辺部に、加工割れのない高精度加工により非切削部１０のない一定幅で連続した高品質のＬ字状の帯状切削部８Ｌを形成することが可能になる。
また、この切削動作に先立って、長孔１５ａ、１５ｂ内に固定位置を選択して、切削刃３ａ、３ｂを螺子６ａ、６ｂをナット１４ａ、１４ｂにそれぞれ螺合することにより、帯状切削部８Ｌの深さを簡単に設定することが可能になる。
このようにして、本実施の形態によると、ＡＬＣパネル７を建築物の外壁などに利用する場合に、取付作業に使用する各種の金具、ボルト、ビスなどの取付付帯物が、ＡＬＣパネル７のパネル面から突出することを完全に防止し、建築物の意匠性を高めることが可能になる。 As described above, in the present embodiment, the support 1 is pressed against the panel surface at the edge of the ALC panel 7 whose edge is cut into an approximately L shape, and the stopper body 2 is stably attached to the side of the panel. The brittle material cutting jig 12 is stably placed on the surface of the ALC panel 7 in contact, and the jig is moved in the direction of arrow A while pressing the support 1 to cut the edge of the ALC panel 7. A strip-shaped cutting portion 8a is formed by the blade 3b. Next, after the jig is moved and arranged in the direction of the arrow B in the edge portion of the ALC panel 7 perpendicular to the belt-like cutting portion 8a, the belt-like cutting portion 8b is formed on the edge portion of the ALC panel 7 with the cutting blade 3b. By moving the jig in the direction opposite to the arrow B and cutting with the cutting blade 3a, the edge of the ALC panel 7 has a constant width without the non-cutting part 10 by high-precision machining without machining cracks. It becomes possible to form a continuous high-quality L-shaped strip-shaped cutting portion 8L.
Prior to this cutting operation, a fixing position is selected in the long holes 15a and 15b, and the cutting blades 3a and 3b are screwed into the screws 6a and 6b and the nuts 14a and 14b, respectively. It is possible to easily set the depth of the.

It is also possible to set the distance between the end faces of 2 to be greater than the cutting edge width a of the cutting blades 3a, 3b, and the distance between the end faces of the stopper body 2 facing the cutting blade 3a to b <a, or as shown in FIG. As described above, any of the distances between the end faces of the stopper body 2 facing the cutting blades 3a and 3b can be set to be equal to or larger than the blade width a.

また、切削刃３ａ、３ｂの支持体１の板面に対する傾斜角αも、以上に説明した実施の形態での４５°に限定されず、発明者等の実験によると、傾斜角αを１０°〜６０°の範囲で選択して快適な切削を行なうことが明らかであり、切削対象となるＡＬＣパネルもほぼ直角に交差するＬ字状屈曲部を有するものに限定されず、一般には、縁辺が所定の角度で交差する屈折線状に切断されたＡＬＣパネルを対象とすることが可能である。
さらに、傾斜面１６ａ、１６ｂに対する切削刃３ａ、３ｂの固定も、傾斜面１６ａ、１６ｂの所定位置に取付孔を板面を貫通して形成し、この取付孔に通じてナットを取付台５の裏面に溶着し、刃先までの長さが異なる数種の切削刃３ａ、３ｂを予め用意しておき、現場で必要な長さの切削刃３ａ、３ｂを選択して取付台５の傾斜面１６ａ、１６ｂに取付孔位置に螺合して、位置調整操作なしに固定が可能でより作業性のよい構成にすることも可能である。 Further, the inclination angle α of the cutting blades 3a and 3b with respect to the plate surface of the support 1 is not limited to 45 ° in the above-described embodiment, and according to experiments by the inventors, the inclination angle α is 10 °. It is clear that a comfortable cutting can be performed by selecting within a range of ˜60 °, and the ALC panel to be cut is not limited to one having an L-shaped bent portion that intersects at a substantially right angle. It is possible to target an ALC panel cut into a refracting line that intersects at a predetermined angle.
Further, the cutting blades 3a and 3b are fixed to the inclined surfaces 16a and 16b by forming a mounting hole through the plate surface at a predetermined position of the inclined surfaces 16a and 16b.
