Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing sheet stone in which only the surface is cut and subjected to uneven finishing such as bumping.

0002

BACKGROUND OF THE INVENTION Hitherto, stone slabs have been known which are cut only on the surface and have an uneven finishing process such as bumping. By the way, the conventional method for obtaining these slab stones was to grind rough stones into slabs with a predetermined thickness, and then pound the surface of the slabs with a tool such as a hammer to create an uneven finish. .

0003

[Problem to be solved by the invention] According to the conventional method described above, if the plate thickness is thin, it will break due to the impact during uneven finishing, so until now it has been necessary to have a plate thickness of at least 60 mm. and no smaller sheet stones were obtained. Therefore, there are problems in that not only the product cost is high, but also the overall weight is heavy, which severely limits the application. The object of the present invention is to provide a method for manufacturing sheet stone that can significantly reduce product costs and that can be applied to a wide range of applications, cutting only the surface and applying uneven finishing such as bumping. .

0004

[Means for Solving the Problems] The method of manufacturing sheet stone in which only the surface of the stone is cut and subjected to an uneven finishing process such as bumping is characterized in that both surfaces or both surfaces and the circumferential surface of a rough stone made of a rectangular parallelepiped are pre-prepared. After applying an uneven finishing process such as pre-cutting and bumping, the processed stone that has been subjected to the uneven finishing process is ground into multiple pieces in a direction parallel to both surfaces to obtain a slate stone. It is characterized by

[0005]

[Operation] According to the manufacturing method of the present invention, only the surface is cut,
The thickness of the plate is 60mm with uneven finishing such as bumps.
The following thin slabs can be easily obtained. Furthermore, the thickness of the slab stone can be changed freely, and sheet stone with an uneven finish, which has not been previously available, can be obtained at low cost and with high productivity.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1(a) and 1(b) show the manufacturing process of the thin slab stone of the present invention. This manufacturing process involves cutting only the surfaces 2a and 2b of the rough stone 1 as shown in FIG. As shown in FIG. 1(b), the processed stone 3 that has been subjected to the uneven finishing process in the first step is cut with a diamond cutter D or the like in a direction parallel to both surfaces 2a and 2b. A plurality of (four in this embodiment) thin slab stones 4a,
The second step consists of forming 4b, 4c, and 4d.

[0007] The rough stone 1 has, for example, a long side 1a of 950 m.
It is a rectangular parallelepiped with a size of m, a short side 1b of 650 mm, and a plate thickness 1c of 150 mm. In addition, in the illustrated embodiment, one surface 2a of the rough stone 1 is subjected to a rough finishing process, and only the other surface 2b is subjected to a cut finishing process, but these uneven finishing processes can be applied to both surfaces. Surface 2a, 2
b may be the same, and may be arbitrarily selected depending on the order. Furthermore, in this embodiment, the diamond cutter D has three teeth, each having a thickness of 10 mm and an interval of 30 mm.
A sheet stone 4a having a diameter of 0 mm and having a bumped finish on its surface, and sheet stones 4b and 4c with flat surfaces,
A sheet stone 4d whose surface is cut and finished is obtained. In addition, by changing the number or spacing of the teeth 5 of the diamond cutter D, the sheet stones 4a to 4 can be
The thickness or the number of sheets d can be changed freely and can be arbitrarily selected depending on the order.

Laminated stone 4 obtained through the above manufacturing process
A to 4d are cut to a standard length by cutting the four sides as shown in Figures 2(a) to (d), for example, 900 mm for the long side and 600 m for the short side.
m, a sheet stone product 41a with a thickness of 30 mm and a bumped finish on the surface, a sheet stone product 41d with a cut finish only on the surface, and a flat surface with a polishing finish or burner finish. The sheet stone products 41b and 41c can be made of stone products 41b and 41c. In addition, in the above-mentioned embodiment, it was explained that the surfaces 2a and 2b of the rough stone 1 are subjected to an uneven finishing process such as bumping and chiseling in the first step, but the same uneven finishing process is also applied to the peripheral surface. Of course, it may also be applied. The laminated stone product thus obtained is suitable for use in corner sections of building exteriors.

[0009]

[Effects of the Invention] As explained in detail above, the present invention has the following features:
By pre-cutting both surfaces or both surfaces and the circumference of the rough stone and applying an uneven finishing process such as knurling, the processed stone that has been subjected to the uneven finishing process is ground into a thin plate shape.
This is a manufacturing method that obtains a thin slab stone that is cut only on the surface and has an uneven finish such as bumping out, so it is possible to achieve an uneven finish with a thickness of 60 mm or less, which was impossible with conventional methods due to cracking. Laminated stone can be easily produced. This allows product costs to be significantly reduced.

[0010] Another advantage is that the same type of stone can be used to create sheet stones that have been cut only on the surface and have been given an uneven finishing process such as bumping, and ordinary sheet stones that have a flat surface. There is.
