DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, stone powder and a transparent or semitransparent thermosetting synthetic resin are placed in a rectangular molding space of a lower mold 1 having a transfer shape 1a formed by reversing the uneven shape of the surface of natural stone. The kneaded molten material 2 is injected. In addition, slide type auxiliary molds 5a and 5b are provided on the upper surface 1T of the lower mold 1 along substantially the outer periphery of the molding space for processing the fiber sheet 3 at the outer peripheral end of the outer casing. It Next, the fibrous sheet 3 is placed from the upper surface side of the auxiliary molds 5a and 5b onto the molten material 2, then the upper mold 4 is placed, and pressing pressure is applied by a pressing device (not shown).

After that, the auxiliary molds 5a and 5b are slid and removed to integrally form a pair of insert grooves 6 and insert pieces 7 extending horizontally in the outer peripheral direction on the fiber sheet 3 at the outer peripheral end. . At the same time, the groove to be inserted 6
A supporting piece 8 which is an upper facing piece and which protrudes in the outer peripheral direction is formed. Further, the auxiliary molds 5a and 5b and the molding space wall form an outer peripheral surface perpendicular to the inserted groove 6 and the inserting piece 7. The contact surface 3A is molded.

As shown in FIG. 2, in the lower mold 1 described above, a molten material 12 such as gypsum or FRP (fiber reinforced resin) is poured into a frame mold 11, and a natural stone 13 is placed on the molten material 12. , The uneven shape 13 a of the surface of the natural stone 13 is transferred to the melting material 12. The molten material 12 is solidified to form the lower mold 1.

As the thermosetting synthetic resin of the above-mentioned melting material 2, transparent or semitransparent resin such as polyester, epoxy or acryl is used. Further, as the stone powder of the melted material 2, crushed rock, stone treated waste, or the like is used. Outline by volume ratio, resin 2
It is desirable that 80% of stone powder is mixed with 0%. Further, as the fibrous sheet 3, glass or carbon fibers, cloth, etc. are used, and the fibrous sheet 3 is pressed against the back surface of the molten material 2 by the above pressing pressure, and the thermosetting synthetic resin of the molten material 2 is impregnated and cured. Then, as shown in FIG. 3, a rectangular inner and outer packaging material 10 having a stone pattern on the surface is formed.
Is molded. The molten material 2 in FIG. 1 is solidified to form an artificial stone panel 9.

The insertion groove 6 and the insertion piece 7 are
As shown in FIG. 3, the inner and outer casings 10 are formed on each side of the fiber sheet 3 at the outer peripheral edge of the fiber sheet 3 with the diagonal line as a boundary to form a pair. That is, in FIG. 3, the inserted groove 6 and the supported piece 8 are formed on the right side and the upper side of the fiber sheet 3, and the inserted groove 6 is inserted on the left side and the lower side of the fiber sheet 3. An insert piece 7 is formed. Further, notches 8A are provided at the left end and the lower end of the supported piece 8 to eliminate interference.

In order to form the inner wall or the outer wall by arranging the inner and outer covering materials 10 side by side in the vertical and horizontal directions, the supported piece 8 is fixed to the wall base 15 with a fixing member 14 such as bolts or nails. . Then, in FIG. 3, since there is a groove 6 to be inserted on the upper side and the right side, the next adjacent inner / exterior material 1 is located here.
After inserting the insertion piece 7 of 0 to bring the abutting surfaces 3A into contact with each other, the supported pieces 8 on the upper side and the right side of the exterior material 10 are also fixed to the wall foundation 15 in the same manner. By repeating this operation, the inner and outer casings 10 are vertically and horizontally arranged side by side to form an inner wall or an outer wall.

According to the above-mentioned embodiment, the inner and outer covering materials 10 having a stone surface pattern are arranged side by side by simply inserting the inserting pieces 7 into the inserted grooves 6 of the adjacent inner and outer covering materials 10. The construction of the inner wall or the outer wall becomes very easy.

Further, the abutting surface 3A facilitates accurate positioning of the inner and outer casings 10 with each other, and also improves the structural strength. Furthermore, the abutting surface 3A is
Since the weight of the exterior material 10 is received, an excessive load is not applied to the insertion piece 7.

Further, since the uneven shape of the natural stone of the lower mold 1 is transferred to the surface of the artificial stone panel 9 and the stone powder is contained together with it, a high-quality stone surface pattern is obtained. Further, since the artificial stone panel 9 contains the resin, the weight can be reduced, and the transportation and the construction can be facilitated. Further, since the steps of cutting and polishing are unnecessary in manufacturing, the working environment at the time of manufacturing is good, and the manufacturing cost can be reduced.

Further, since the fiber sheet 3 fixed to the back surface of the artificial stone panel 9 is hardened, the strength of the artificial stone panel 9 can be improved and the artificial stone panel 9 is not easily cracked. Even if the artificial stone panel 9 is cracked by being dropped or the like, the fiber sheet 3 is fixed to the back surface of the artificial stone panel 9, so that the fragments are not scattered and the safety can be improved.

Although the groove 6 to be inserted is formed of the fiber sheet 3 in the above embodiment, it may be formed between the fiber sheet 3 and the molten material 2 at the outer peripheral ends of the inner and outer packaging materials 10. . This can be achieved by changing the auxiliary type.
