Description

[Detailed description of the invention] [Industrial application field] This invention is a method for processing stone materials, more specifically.

The present invention relates to a method for processing a backing plate that remains after removing a necessary portion from raw stone so that it can be used for tiles, etc.

[Conventional technology]

For example, as shown in FIG. 5, when a plurality of sawn boards 2 are cut out from a cubic raw stone 1, back boards 3 are formed at both ends of the board.

The back plate 3 has a flat surface 3a on which it meets the sawn board 2, but the other surface is a rough surface 3b, which is uneven and uneven.

The backboard 3 as described above may be used as a tile to be laid on a sidewalk, and in order to make a tile, the four peripheral edges must be cut and processed into a certain planar size.

Figures 6 and 7 show the conventional circumferential cutting method for the back plate 3 as described above, and in Figure 6, the back plate 3 is placed on a cart 4t with the raw stone surface 3b facing down. 7, the back plate 3 is placed on the cart 4 with the flat surface 3a facing down.

[Problem that the invention seeks to solve]

By the way, in the former cutting method, the arrangement of the back plate 3 becomes unstable and the cut of the knife 6 is not perpendicular to the flat surface 3a, so it is difficult to cut tiles whose four peripheral edges are perpendicular to the flat surface 3a. The problem is that you can't get it.

Further, although the latter cutting method makes the back plate 3 stable for one truck 4, the thickness of the back plate 3 is uneven.

The cutting conditions of the blade 6 change as the cutting progresses.

In particular, there is a problem that the lower corner of the cut portion of the back plate 3 is chipped.

Figure 8 shows the laid state of the tiles 7 cut out by the above-mentioned cutting method, and since the bottom surface of the tiles 7 has an uneven surface just like raw stone, 1 mortar 8 is filled evenly over the entire bottom surface. There is a problem in that it is not possible to determine which label should be attached during installation.

As described above, it is extremely difficult to cut around the back plate 3, and at the same time, it is difficult to install it as a tile, so the current situation is that the back plate 3 is discarded as it is.

This invention was made in order to solve the above-mentioned problems and realize the effective use of the backboard, and it is possible to stably and accurately cut the four edges of the backboard, making it easier to install it as a tile. The purpose of this invention is to provide a stone processing method that allows for accurate construction. The raw stone surface of the backboard that remains after removal is lined with mortar to make the thickness uniform, and then the four edges of the backboard are cut to create tiles.

[For production]

The raw stone surfaces of the back plates remaining at both ends of the raw stone are lined with mortar to form a laminate of the back plates and mortar, and the thickness of this laminate is made uniform.

Next, the four peripheral edges of the laminate are cut to create tiles with a certain thickness and planar size.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5 of the accompanying drawings.

As shown in FIG. 5, for the back plate 3 that remains after removing the necessary parts of the raw stone 1, as shown in FIG.

The surface 3b of the raw stone is lined with mortar 11 to form a laminate 12 of the back plate 3 and mortar 11.

The mortar 11 is used to line the laminate 12 so that its thickness is constant, and then the four peripheries of the laminate 12 are cut to form tiles 13 of a predetermined size.

FIG. 2 shows a row in which the laminate 12 is cut by the blade 6 of the circular saw 5. Since it can be stably placed on the cart 4, it can be cut accurately from the back plate 3 side to form tiles 13. .

Figure 3 is an example in which the surrounding machining is performed on the compression side.1
If a groove 14 is formed with a circular saw on the surface of the back plate 3 of the laminate 12 placed on the cart 4, and compression is performed from below t in the groove 14 using the cutting edge 15, 16 of the compression side machine, Since the cutting edge hits the tile equally, it breaks cleanly and becomes tile 13.

Figure 4 shows a tile 13 formed by the above processing.
The lower surface of the tile 13 is made flat by the mortar 11, so it makes complete contact with the base mortar 17 and can be installed accurately.

〔effect〕

As described above, according to this invention, the necessary parts are removed from the rough stone, the remaining backboard is lined with mortar to make the thickness constant, and the periphery of this laminate is finished, so it is considered waste material. The peripheral processing of the backboard can be carried out at right angles to the surface and accurately, allowing the backboard to be used for sidewalk tiles, etc., and making effective use of the backboard.

Further, since the back plate and mortar laminate have equal thickness, installation work can be carried out accurately when used as a tile or the like.
