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, a frame member 20 made of an incombustible material such as iron is set in the rectangular molding space of the lower mold 1 having a transfer shape 1a formed by reversing the uneven shape of the surface of natural stone. The frame member 20 includes horizontal pieces 21 and 22 provided along the outer periphery of the molding space and held on the upper surface 1T side of the lower mold 1, and the horizontal pieces 21 and 22 along the wall of the molding space. And a frame surface 24 which is connected by a connecting piece 23 which rises and falls and which is installed at a substantially intermediate height position of the molding space. The frame surface 24 bridges the connecting piece 23 in a cross shape. Iron bar 25 (Fig. 3) or wire mesh 26
(Fig. 4) etc. The horizontal piece is divided at the pair of diagonal apex portions 20s, 20s of the frame member 20, and the two L-shaped horizontal pieces 21, 22 face each other to form a substantially rectangular shape. Of these horizontal pieces 21, 22, the horizontal piece 21 forming the upper and right sides in FIGS. 3 and 4 is formed at a position higher than the horizontal piece 22 forming the lower and left sides.

The frame surface 24 is installed in the molding space while the horizontal piece 22 is held by the upper surface 1T of the lower die 1 and the horizontal piece 21 is held by the slide type auxiliary die 5, and then, A molten material 2 in which stone powder and a transparent or translucent thermosetting synthetic resin are kneaded is injected into the molding space and a pressing pressure is applied to produce the inner and outer packaging materials 10 as shown in FIG.

At the outer peripheral ends of the inner and outer casings 10 manufactured as described above, that is, on the left side and the lower side as shown in FIG. Further, the auxiliary mold 5 is removed on the right side and the upper side, so that the groove 6 to be inserted is formed between the horizontal piece 21 and the molten material 2. Further, a vertical butting surface 3A is formed by the wall of the molding space, and the horizontal piece 21 becomes the supported piece 8 protruding in the outer peripheral direction. Further, the vertical pieces 21 and 22 are not provided on the vertical angle portions 20s and 20s in order to eliminate the interference between the insertion pieces 7.

As shown in FIG. 2, the lower mold 1 described above is prepared by injecting a liquid material 12 such as gypsum or FRP (fiber reinforced resin) into a frame mold 11 and placing a natural stone 13 on the liquid 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, a transparent or semitransparent resin such as polyester, epoxy or acrylic 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%. The molten material 2 in FIG. 1 is solidified into an artificial stone panel 9 as shown in FIG. 6 having a stone pattern on the surface.

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. 6, 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 casing materials 10 having the stone surface pattern are arranged in parallel by simply inserting the insertion grooves 6 and the insertion pieces 7 of the inner and outer casing materials 10 adjacent to each other. The construction of the inner wall or the outer wall becomes very easy. Moreover, since the frame member 20 is made of a non-combustible material,
The inner and outer materials 10 can be used for a fireproof structure.

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. Since the steps of cutting and polishing are unnecessary in manufacturing, the working environment during manufacturing is good, and the manufacturing cost can be reduced.

Further, the frame surface 24 of the iron bar 25, the wire netting 26, etc.
Is intervened in the artificial stone panel 9, the strength can be improved and cracking is less likely to occur. Even if the artificial stone panel 9 is cracked by being dropped or the like, it is possible to suppress the scattering of the fragments and improve the safety.
