Since the decorative film layer is formed of one kind of synthetic resin material in which colored particles such as crushed stone particles, ceramic particles, and glass particles are mixed, it seems that only the same kind of stone is used for masonry. In addition, there is a problem that one convex portion corresponding to one stone has a substantially uniform color tone and changes little, and it is difficult to see it as a natural stone masonry in which the color tone changes for each stone stacked. Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to make it possible to change the color tone and pattern of each stone itself, and to change the color tone for each stone piled up. An object of the present invention is to provide a decorative formwork that can be used.

That is, the decorative formwork for concrete according to the present invention comprises a formwork body made of a synthetic resin foam having a plurality of recesses for forming a masonry pattern on the concrete surface, on the side where the concrete is to be cast. In the decorative formwork for concrete, which is formed on the surface in the recess and is transferred to the concrete surface to decorate the surface of the masonry pattern, the decorative coating layer is a colored granular material having a different color tone. Is formed by spraying two or more kinds of synthetic resin materials that are mixed and formed in different color to each other. By adopting this configuration, the decorative coating layer formed in the concave portion is formed of two or more kinds of synthetic resin materials having different color tones depending on the amount of spraying, in a variety of patterns such as mottled patterns and striped patterns. When transferred to the surface, the concrete surface is also decorated with various patterns.

If so, the pattern and color tone will change for each stone that constitutes the masonry pattern, and it will be possible to make the appearance look more like a natural stone piling. When the synthetic resin foam is a polystyrene-ethylene copolymer or polypropylene, the decorative coating layer is easily released from the mold body, and the decorative coating layer is easily transferred to the concrete surface. Further, by applying a release agent to the inner surface of the mold body, even when general polystyrene is used as the material of the mold body, it is easier to release the decorative coating layer from the mold body. Therefore, it is possible to reliably transfer the decorative coating layer to the concrete surface.

First, the structure of a decorative formwork 10 for concrete according to the present invention will be described with reference to FIGS. 1 and 6. The decorative frame 10 for concrete is a synthetic resin foam in which a plurality of recesses 14 for forming a masonry pattern on the concrete surface are formed on the surface 12 on which concrete is to be poured (hereinafter referred to as "concrete placement surface"). It has a form body 16 composed of a body, and a decorative film layer 18 formed on the surface inside the recess 14 and transferred to the concrete surface to decorate the surface of the masonry pattern. A flat joint portion 20 is formed between the recesses 14 so as to be on the same plane. Considering the releasability of the synthetic resin foam used in the mold body 16 from the decorative film layer 18,
For example, it is preferable to use a polyolefin resin material such as polystyrene-ethylene copolymer or polypropylene, but a general resin material such as rubber may be used.
Further, in order to further improve the releasability, a configuration may be adopted in which a release agent such as silicone is applied between the decorative film layer 18 and the surface of the mold body 16 (which may be the inner surface of the mold body 16). . Further, according to this configuration, the releasability of the decorative coating layer 18 can be secured even when the conventionally used polystyrene is used for the mold body. In addition, each recess 14a-1
The decorative coating layer 18 within 4 g is formed by superposing and spraying two or more kinds (two kinds in this example) of different synthetic resin materials by a method described later.

In addition, using colored granules such as crushed stone grains, ceramic grains, and glass grains having different colors, synthetic resin materials for forming the decorative film layer 18 having different color tones are prepared in advance. Further, the color tone may be changed by mixing colored granules of different kinds and different colors into one synthetic resin material. Here, the color tone
When the color of the synthetic resin material itself looks mainly, or when the white colored synthetic resin material is mixed with the black colored particles, it looks gray as a whole, and when the red colored particles are mixed, the color looks like pink as a whole. So,
In addition, it is assumed that when the colored particles are visually recognized, they appear as a speckled pattern, and when they are unevenly mixed, they appear as a striped pattern. In this example, the seven concave portions 14a to 14g are divided into three groups, and the respective decorative film layers 18 are formed by overlapping and spraying two kinds of synthetic resin materials having different color tones.
2) Prepare synthetic resin materials A to F having different color tones. Instead of using synthetic resin materials having different color tones, for example, three types of synthetic resin materials having different color tones are prepared, and two types of them are used in combination so that the recesses 14a to The pattern and color tone of the decorative film layer 18 formed on 14 g may be changed. As the first step, the concave portion 14 of the decorative form 10
An oil-based mold release agent (not shown) such as silicone is applied to the concrete placing surface 12 on which a to 14 g are formed. Note that this step may be omitted if the decorative mold 10 itself is formed using, for example, a polystyrene-ethylene copolymer or a polyolefin resin material such as polypropylene and has good mold releasability. .

装飾皮膜層１８を形成する。In the second step, the opening 26 of the concrete placing surface 12 of the mold body 16 has recesses 14a to 14g.
The mask plate 24a is arranged so as to coincide with the corresponding predetermined concave portions 14b, 14d, 14g of the above. In the third step, two kinds of synthetic resin materials A and B among the six kinds of synthetic resin materials are sprayed over the mask plate 24a by using a spray gun or the like. At this time, as shown in FIG. 6 (a cross-sectional view of the concave portion 14g is shown as an example), the synthetic resin material A to be sprayed first is the concave portion 14b,
Instead of spraying on the entire surface of 14d and 14g, spraying is performed while leaving a non-sprayed portion (unattached portion).
Further, the synthetic resin material B to be sprayed later is recessed 14b, 14d, 14g so as to cover at least the unattached portion.
The inner surface is sprayed so as to be overlaid on the first synthetic resin material A. While sequentially replacing the mask plates with the mask plates 24b and 24c in the above second to third steps,
Further, the synthetic resin material is replaced with C and D, and then with E and F, to form the decorative coating layer 18 on all the recesses 14a to 14g as shown in FIG.

Since the synthetic resin material is not blown in, it is possible to surely form the decorative film layer 18 with different colors even if the concave portions are adjacent to each other. Even if the color tone of the synthetic resin material used for forming the decorative film layer 18 is not different, two or more kinds of synthetic resin materials having different color tones are used for forming the decorative film layer 18 of at least one recess. If this is done, by subtly varying the amount of spraying, a different pattern (speckled pattern,
It is also possible to easily form a striped pattern or the like).

A concrete material 30 is placed between the mold and the frame 28.
After curing and hardening, as shown in FIG. 8, the makeup mold 10 and the mold 28
Is peeled off from the concrete plate 32. At this time, the decorative film layer 18 formed on the concrete placing surface 12 of the decorative form 10 is transferred to the surface of the concrete board 32. Decorative film layer 1 formed in the concave portions 14a to 14g of the decorative form 10
Pattern 8 is different for each stone, and the color tone of adjacent stones is also different, so a pattern very similar to the pattern of natural stones with slightly different colors and patterns ( The pattern shown in FIG. 5) can be formed on the surface of the concrete board 32. Therefore, it has become possible to easily form a granite-like pattern having a change in color tone and pattern on the surface of the concrete plate in one stone itself, which has been difficult with the conventional decorative formwork.
