[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for manufacturing wall materials, particularly precast concrete wall materials in which natural stone-like tiles having irregular irregularities on the surface are embedded.

0002

BACKGROUND OF THE INVENTION Conventionally, wall materials made of precast concrete with tiles embedded in the surface have been known. In this wall material, for example, as shown in FIG. 7, a plurality of tiles 2a are continuously arranged side by side on the surface of a base material 1a made of a flat plate or sheet material with the surface facing downward and having a joint width between them. Then, these tiles 2a are surrounded by a frame member 3a, concrete 4a is poured into the frame member 3a and solidified, and then the base member 1a and the frame member 3a are removed.

However, the conventional manufacturing method is limited to the case where the surface of the tile 2a to be buried is flat, and when using the tile 2b having irregular irregularities 4a on the surface as shown in FIG. It was difficult to form precast concrete because the tiles arranged side by side on the wall material 1a were irregularly sloped, and an experienced worker manually attached the tiles 2b to the surface of the wall material on site. There was a problem.

Problem to be Solved by the Invention The problem to be solved by the present invention is that it has not been possible to manufacture a wall material made of precast concrete using tiles having irregularities on the surface.

[0005]

[Means for Solving the Problems] The manufacturing method of the present invention is such that tiles having irregularities on their surfaces are continuously formed on the surface of a base with a joint width approximately equal to the planar shape of the tiles. The uneven portion is housed in a plurality of recesses of the same shape, and a part of the outer circumferential surface is exposed and fitted so as to be kept substantially horizontal, and a joint member is interposed between the exposed outer circumferential surfaces facing each other. After that, concrete is poured into the space formed by the frame arranged along the outer periphery of the base and the base and solidified, and then the base and the frame are removed. , the manufacturing device comprises a base in which a plurality of recesses are continuously formed with joint widths each other, each having a depth that is substantially the same as the planar shape of a tile having an uneven surface and having a depth sufficient to accommodate the uneven portion. and a concrete pouring frame disposed along the outer periphery of the base, and furthermore, in such a configuration, the base is made of styrofoam resin, and has an uneven surface. To achieve the purpose of manufacturing wall materials that are precast concrete using tiles that have

[0006]

[Operation] The tile is fitted into the recess formed in the base surrounded by the frame, with the uneven parts formed on its surface accommodated, and a part of the outer circumferential surface exposed, keeping it almost horizontal. After flowing in and solidifying, the base and frame are removed.

[0007]

[Embodiment] An embodiment of the present invention will be explained based on the drawings. FIGS. 1 and 2 show an embodiment of the manufacturing apparatus of the present invention, and as shown in FIG. A tile made of styrofoam resin in which a plurality of recesses 3 having a planar shape substantially the same as the planar shape of the tile 1 having the tile 2 and having a depth sufficient to accommodate the uneven portions 2 are formed continuously in the front, rear, left and right directions with joint widths between each other. It is composed of a base 4 having a predetermined planar shape, and a concrete pouring frame 5 arranged along the outer periphery of the base 4.

In order to manufacture wall materials using such a manufacturing apparatus, as shown in FIG. Insert it with a part of it exposed and keeping it almost horizontal. At this time, the tile 1 used in this example has a narrow flat edge 7 at the outer peripheral end of the surface, and this edge 7
is engaged with a step 8 formed at the opening edge of the recess 3 formed on the surface of the base 4, thereby exposing a part of the outer circumferential surface 6 and keeping it substantially horizontal. Next, either in advance or after fitting the tile 1 into the recess 3, concrete 10 is poured into the space formed by the frame 5 and the base 4 installed along the outer peripheral edge 9 of the base 4 and solidified. After that, the frame body 5 can be removed.

According to this embodiment, a wall material made of precast concrete using tiles 1 having uneven portions 2 on the surface can be manufactured very easily. In addition, since the tile 1 is fitted into the recess 3 formed in the base 4 and there is no gap between the two, the concrete that has flowed onto the surface of the base 4 is placed in the recess 3 of the tile 1. It does not flow into or adhere to the surface area. Therefore, beautiful products can be obtained. In particular, in this embodiment, since the base 4 is made of a polystyrene foam resin having elasticity, the inner shape of the recess 3 can be made slightly smaller than the outer shape of the tile 1, and the tile 1 can be press-fitted into the recess 3. Since the tile 1 is tightly fitted into the recess 3, an extremely beautiful product can be obtained.

[0010] Also, since it uses styrofoam resin, it can be manufactured very easily, and it can be used repeatedly or thrown away without any problems and is economically advantageous. Needless to say, it may be used.

Furthermore, as shown in FIG. 3, wall materials used in the corners can also be manufactured in the same manner.

FIG. 4 shows an embodiment of the manufacturing method according to the present invention, and the overall structure and operation and effects are almost the same as those of the embodiment described above, except that After fitting the tile 1 into the recess 3, a ready-made joint member 1 is inserted between the mutually opposing outer peripheral surfaces 6, 6 of the adjacent tiles 1.
The difference is that 1 is inserted. According to this embodiment, since the joint member 11 is exposed on the surface of the manufactured wall material, a more beautiful product can be obtained. Further, since the concrete 10 for pouring does not come into direct contact with the base 4, the base 4 can be reused for a long period of time without being contaminated or damaged.

FIG. 5 shows a different embodiment of the manufacturing apparatus according to the present invention, and the overall structure and operation and effects are almost the same as those of the embodiment described above, but the embodiment shown in FIGS. A wall material is formed using a tile 1 that does not have a narrow flat edge 7 at the outer peripheral edge of the surface as in the example, and a base 4 as shown in FIGS. 2 and 3. The difference is that a step 8 is not formed at the opening edge of the recess 3 formed on the surface of the recess 3 . Therefore, when the base 4 is made of an elastic material such as elastic polystyrene resin, the inner shape of the recess 3 is made slightly smaller than the outer diameter of the tile 1, and the tile 1 is press-fitted into the recess 3. By doing so, the tile 1 can be fitted into the recess 3 while accommodating the uneven part 2 and exposing a part of the outer circumferential surface 6 and keeping it almost horizontal. When the particulate material 12 such as silicone resin is placed, the tile 1 can be fitted into the recess 3 very stably and flatly.

FIG. 6 shows a still different embodiment of the manufacturing apparatus according to the present invention, and the overall structure and operation/effects are almost the same as those of the above-mentioned embodiment. Unlike the case where a large number of recesses 3 are formed on the surface of the base member 13, a plurality of base members 13 each having one recess 3 for fitting the tile 1 are joined or glued together to form a single base 4. is formed. Therefore, the base member 13
By arranging the required number of wafers in parallel in the front, back, left and right directions, it is possible to manufacture products of desired shape and size, which is extremely convenient.

[0015]

According to the present invention, the irregularities formed on the surface of the tile are accommodated in the recess formed in the base surrounded by the frame, and a part of the outer peripheral surface is exposed to keep the tile almost horizontal. It is then fitted and concrete is poured into it. Therefore, a wall material made of precast concrete using tiles having irregularities on the surface can be manufactured very easily.
