DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for manufacturing an inlaid product according to the present invention will be described below in detail with reference to an embodiment shown in the accompanying drawings.

First, a design concept of a metal inlay pattern to be formed and used on a surface of a concrete product is determined, and the image is drawn using a computer. In the case of hand-drawing,
Scan to a computer with a scanner. Thereafter, if necessary, adjustments are made on the CRT by enlargement, reduction, inversion, synthesis, etc., and the image (pattern) data is stored in the memory.

Image data is read from the memory, and as shown in FIG. 1, a groove pattern 12 corresponding to a metal inlay pattern described later is formed on the surface 11 of the calcium silicate plate 10 using an NC control milling machine.

In general, good mold conditions include sufficient heat resistance, good cutting (working) properties, lightweight but constant mechanical strength, and good handleability. (Bending strength: 10 kg / cm ² or more, Compressive strength:
(10 kg / cm ² or more), safety, good air permeability for degassing, low cost and good economical efficiency, etc.
Satisfies all of these conditions.

Next, as shown in FIG.
Molten metals such as the copper alloys, zinc alloys and aluminum alloys mentioned above
Cast 13 in.

At this time, the thermal conductivity of the calcium silicate plate 10 is extremely small at 0.047 kcal / mhdeg, and the heat loss of the molten metal is small. Can be cast.

After the molten metal 13 has hardened, the metal inlay 14 is removed from the calcium silicate plate 10, as shown in FIG.

As shown in FIG. 4, the cleaned metal inlay pattern piece 14 is placed in a mold 15 and filled with concrete 16. The concrete 16 may be an ordinary mixture of cement, sand and water, or may be a resin concrete mainly containing a synthetic resin such as unsaturated polyester.

Thereafter, as shown in FIG. 5, the surface is polished, and the surfaces of the metal inlay pattern pieces 14 and the concrete 16 appear glossy, and as shown in FIG. 18 can be obtained.

As shown in FIG. 2, a bridge forming portion 12a is provided in a part of the groove pattern 12, so that a bridge 14a is formed in the middle of the metal inlay pattern piece 14 as shown in FIG. Can be. Therefore, as shown in FIG. 6, even when the metal inlaid patterns 17 and 18 are independently provided at the separated positions, the metal inlaid patterns are accurately positioned on the surface of the inlaid product A.
17, 18 can be formed.

FIGS. 7 and 8 show another embodiment of the method for producing a product with a metal inlay pattern according to the present invention.

The present embodiment is substantially similar to the metal inlay pattern 20,2.
It is characterized in that 1,22 are formed from dissimilar metals.

That is, in FIG. 7, the metal inlaid patterns 20, 22
Is made of a zinc-based alloy, while the metal inlay 21 is made of a copper-based alloy. Therefore, the product A with a metal inlay pattern can be a design in which silver and gold are combined, and the decoration effect can be enhanced.

The manufacturing process of the product A with the metal inlay pattern is substantially the same as the manufacturing process described with reference to FIGS. 1 to 5, except that a step of providing a partition in the groove pattern 12 is performed. Required separately.

That is, as shown in FIG. 8, before the molten metal is cast into the groove pattern 12, the groove pattern 12 is partitioned by the partition plate 23 having the anchors 23a and 23b on both surfaces. By casting a zinc-based alloy in a molten state into the groove, and casting a copper-based alloy in a molten state into the other groove pattern 12, a product A with a metal inlay pattern made of a dissimilar metal can be manufactured.

At this time, it is preferable that the partition plate 23 be made of the same metal as that of the zinc-based alloy or the copper-based alloy, so that the presence of the partition plate 22 cannot be recognized. be able to.

FIGS. 9 and 10 show another embodiment.
As shown in the figure, groove patterns 32 and 32a corresponding to a metal inlay pattern and an annular groove pattern 33 are formed on the surface of the calcium silicate plate 30 using an NC control milling machine.

A plurality of wide vertical grooves 34 and horizontal grooves 35 are similarly

30 and these grooves 34 and 35 are formed with groove patterns 32 and
Contact 32a, 33.

With this configuration, the calcium silicate plate 3
The molten metal can be quickly spread over the entire surface of the groove 0, can flow into the groove patterns 32, 32a, and 33 in a short time, and can effectively prevent a hardening phenomenon from occurring on the way.

Further, when the molten metal flowing into the grooves 34, 35 hardens, it acts as a lattice-like reinforcing bridge for fixing the metal inlay pattern, so that the spacing between the plurality of metal patterns, that is, the relative positional relationship is reliably maintained. be able to. Therefore, even after the manufacture of the product with the metal pattern is completed, the deformation of the metal pattern can be reliably prevented.

Incidentally, concrete or mortar can also flow into the molding space through a large number of lattice-shaped gaps formed in the lattice-shaped reinforcing bridge, so that concrete or mortar can smoothly flow into the molding space. In addition, the molding operation can be performed smoothly.

[0036]

According to the present invention, a product with a metal inlay pattern is formed into a mold by forming a groove pattern on the surface of a calcium silicate plate, a molten metal is cast into the groove pattern, and a metal inlay pattern piece after curing is cast from the mold. Removed, installed in the mold, filled with concrete in the mold, cured and cured for a certain period of time, take out the concrete product with metal inlay pattern on the surface from the mold, and manufacture by polishing the surface You are going to.

As described above, the mold can be easily formed simply by forming a groove pattern on the surface of the calcium silicate plate, and a product with a metal inlay pattern can be easily and inexpensively manufactured.

In particular, by using a computer or an NC processing machine, a product with a metal inlaid pattern can be manufactured inexpensively and quickly without skill, even in the case of small-lot production of many types.

The width of the groove pattern formed on the surface of the calcium silicate plate can be freely determined.
Not only linear groove patterns, but also planar groove patterns and dot groove patterns can be easily formed. Metal inlay patterns formed on the surface of products with metal inlay patterns are not only linear patterns, but also planar patterns. And a dot pattern can be comprehensively combined, so that the degree of freedom in design can be significantly increased.
