Conventionally used ceramic-based inorganic board materials, such as asbestos slate roofing materials, are manufactured by first manufacturing original boards from inorganic raw materials and cutting them into the desired shape of the roofing material. Since this cutting is performed using a cutter or a press device, the shape of the cut surface is linear, and its appearance has to be mechanically very invariable. Of course, when roofing is done by butt-jointing, it is necessary that the cut surface has a straight shape, but like roofing materials, the side edges are butt-jointed, and the Among the edges, especially the lower edge is exposed to the outside,
In cases where the appearance on the roof is determined by the arrangement of the lower edges, the shape of the exposed portion has an important influence.

The method for cutting an inorganic ceramic board according to the present invention involves contacting one side of the inorganic ceramic board with a blade disposed along the contour of the product shape, while the other side of the inorganic ceramic board is placed along the contour. A part of the edge along the inner side of the blade body runs along the inner side of the blade body with a gap of 0.4 times or less than the thickness of the ceramic inorganic plate material, and the other edge runs along the inner side of the blade body with a gap of 0.4 times or less than the thickness of the ceramic inorganic plate material. The plate material is cut by abutting and pressing a pressing plate formed on the inside with an interval of 0.6 to 1.2 times the thickness of the plate.

成されている。 The method for cutting ceramic inorganic board material of the present invention is to cut a ceramic inorganic board material 1 (hereinafter simply referred to as "board material 1") made of inorganic raw materials such as cement and gypsum on one side (FIG. 3 A and B). The blade body 2 (second
On the other hand, on the other side of the plate 1, a part of the edge 3A (Fig. against
The other edge 3B is 0.6 times the thickness of the plate 1 than the inner side 2A of the blade 2.
It is configured to cut the plate material 1 by abutting and pressing a pressing plate 3, which is formed to be located inside with a constant interval L that is twice to 1.2 times the interval.

According to this invention, the plate material 1 has a shape shown in FIG.
As shown in , the cutting end is cut in a mechanical state, but in the area where there is a gap L between the edges of the blade 2 and the pressing plate 3, shearing force acts on the board 1, and the board Coupled with the fact that 1 is hard, the cut surface is not flat, resulting in a surface condition G 2 that appears when the plate 1 is cut.

保てなくなる。 According to experiments conducted by the present inventors, the distance L between the blade body 2 and the press plate 3 that can achieve the surface conditions G 1 and G 2 is the same as that for ordinary asbestos-cement roofing materials (bending strength of 210 kg/
cm 2 , thickness 4 mm), the surface condition G 1 can be achieved in a range where the horizontal distance between the edges of the blade 2 and the press plate 3 is 0 to 0.4 times the thickness of the plate material to be cut,
In addition, the range that can be clearly defined as surface condition G 2 is 0.6 times or more of the thickness of the plate material, and
If the above-mentioned horizontal interval becomes 1.4 times or more the thickness of the plate material to be cut, an irregularly shaped crack will occur between the blade 2 and the press plate 3, resulting in an irregularly shaped fractured surface, and the shaping property will not be maintained.
従つて、刃体の水平間隔は、それぞれ上記の範
囲とされる。 Therefore, the horizontal spacing between the blades is within the above range.

言うまでもない。 The above explanation has been made regarding roofing materials, but it is not limited to this, and can be similarly applied to ceramic-based inorganic board materials that require changeability in the shape of the end surface, such as wall board materials for interior and exterior use. Needless to say.
以上説明したように発明によれば、一回の切断

As described above, this invention is a ceramic inorganic plate material that can be laid out with a part exposed to the outside, such as roofing material, and the cut surface of the plate is kept in a natural state. If a rich appearance is desired, this can be easily formed in a single cutting process, and the external contour of the cut ceramic inorganic plate material is precisely regulated, so special conditions for use are not required. It can be easily laid out in the same way as before without any additional material.
