とがある。A problem with such a method is that particles of the hardening material may not sufficiently pass through the cloth or nonwoven fabric, and the surface may not be formed clearly. It is. A so-called decorative mold formed of a synthetic resin material or the like is used as a mold plate for molding a hardening material. This decorative mold is one in which irregularities are formed on the contact surface of the mold with the hardening material, for example, by making the surface of the hardening material have irregularities imitating the surface of a stone material or by giving a geometric uneven pattern. If the particles of the hardening material do not come out of the cloth or nonwoven fabric well, the hardening material does not sufficiently enter the unevenness of the decorative form, and the surface is not formed exactly as the unevenness of the decorative form,
In the case of a mold imitating a stone, for example, the convex portion of the surface of the hardened material may be rounded and the feel of the surface of the stone may not be sufficiently expressed.

The invention of the present application can be carried out both in the case where a hardening material is poured into a mold in factory production and the molding is performed, and in the case where the hardening material is cast into the mold and a structure is formed on site. As a mold plate for molding the surface of the cement-based hardening material, a foamed synthetic resin plate, rubber or a wooden plate is adopted, and the surface in contact with the cement-based hardening material is imitated as a stone surface. Irregularities for formation are formed. The nonwoven fabric is arranged along this surface. To dispose may be placed on the surface of the form plate or bonded with an adhesive. The nonwoven fabric contains a coloring material. As the coloring material, a pigment or a dye or a mixture of both is used. Before or after disposing along the form plate, the coloring material is included by applying a solution in which the coloring material is dissolved, for example.

The formwork 1 is a rubber box shape, and the bottom side is a formwork plate 2. Formwork 2 is provided with irregularities on its surface for shaping a simulated stone material. A non-woven fabric 4 in which synthetic resin fibers cut as required are attached to the concave portions 3 of the irregularities with a water-soluble glue.
Is placed. The nonwoven fabric 4 is impregnated with a coloring material. The concrete 5 which is a cement-based hardening material is poured on this. When vibration is given by the vibrator, the concrete 5 convects, but since the coloring material is impregnated in the nonwoven fabric, the concrete 5 is mixed with the concrete 5 little by little. Eventually, the glue melts due to moisture, causing the fibers to break apart. Along with the coloring material, the particles of cement and aggregate in the concrete 5 pass toward the surface of the formwork plate 2 and
Penetrate and mix. Thereby, the colored layer 6 is formed near the surface of the mold plate 2. Also, particles of cement and aggregate enter the irregularities on the surface of the mold plate 2 to clearly form irregularities such as stone surfaces.

And a sheet of nonwoven fabric impregnated with a coloring material is laid thereon. On the surface of the mesh member 7 on the side of the form plate 2, a plurality of protruding portions 8 formed by cutting a part of the mesh material and raising the mesh material are formed. Also, a plurality of protrusions 9 are formed on the opposite side surface. The nonwoven fabric 4 containing the coloring material is placed on the mesh member 7 and concrete 5 is cast. The binder dissolves due to the water content of the concrete, the fibers of the nonwoven fabric 4 are disintegrated, and the concrete 5 in which the coloring material has been permeated or mixed flows toward the surface of the form plate 2. Since the clearance c is formed between the mesh member 7 and the surface of the form plate 2 by the projection 8 of the mesh member 7, the colored layer 6 of the concrete 5 is formed.
Is formed. The protrusion 9 projecting to the opposite side of the mesh member 7 adheres to the concrete 5, and the concrete 5 on both the front and back surfaces of the mesh member 7 is integrated.

A plurality of form plates 2 made of a foamed synthetic resin material are erected and stacked, and are supported by the plywood 10. Unevenness imitating the surface of a stone material is formed on the form plate 2, and a nonwoven fabric 4 is stuck thereon. A weir plate 11 stands upright facing the form plate 2. Concrete 5 is cast between the form plate 2 and the weir plate 11. The non-woven fabric 4 is disintegrated by moisture, and particles of cement and aggregate impregnated and mixed with the coloring material enter the irregularities on the surface of the form plate 2 to create a good atmosphere like a stone surface.

ある。In the above embodiment, the surface hardening agent is not mixed with the coloring material. However, when the cement hardening material is cast in a state where the coloring material does not dry out, the acrylic resin is contained in the coloring material. A surface hardening agent such as the above may be mixed. Even if there are pigments and dyes that are not completely mixed in the cement-based hardening material, the surface hardener hardens them, and the pigments and the like do not drop even when touched by hand. In the embodiment of FIG.
Although the nonwoven fabric is cut into several pieces, it may be used as a single piece of nonwoven fabric. In the embodiment shown in FIGS. 2 and 3, a nonwoven fabric cut into a plurality of pieces may be used. It is also possible to use a plurality of nonwoven fabrics with their edges overlapped.

を損なうことがない。The present invention has the above-described configuration, and can obtain the following effects. Using a nonwoven fabric attached with a binder that dissolves due to the moisture of the cement-based hardening material, and arranging it along the mold plate, the fibers disperse due to the moisture, and the particles of cement and aggregates become closer to the surface of the mold plate. It is possible to satisfactorily get out of the mold, enter the irregularities of the mold plate, and form a good surface with sharp and irregular as the mold surface. Since the coloring material is contained in the nonwoven fabric, the coloring material does not flow even when vibration is applied by the vibrator, and is mixed with the particles of the hardening material from the nonwoven fabric, so that the entire surface of the hardening material can be colored evenly. Since the coloring material is neutral or alkaline, the coloring material is easily blended with the alkaline cement-based hardening material and easily mixed into the hardening material. By interposing the mesh material between the mold plate and the nonwoven fabric, the fibers of the nonwoven fabric do not come out on the surface, and the texture of the stone surface or the like is not impaired.
