Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of decorating a concrete surface.

[0002]

2. Description of the Related Art Conventionally, the following method has been used to apply a decoration made of natural stone-like unevenness to a concrete surface. That is, as shown in FIG. 14, by rolling the roller 11 having a natural stone-like uneven pattern 11a formed on the (pure) concrete placing surface 10a, the uneven pattern 11a of the roller 11 is removed. This is a method of transferring to the concrete placing surface 10a, and then curing and hardening the concrete material 10. In addition to this method, as shown in FIG.
0a is pressed by a board 12 (or a sheet or the like) having a natural stone-like concave-convex pattern 12a formed on the lower surface, and the concave-convex pattern 12a of the board 12 is applied to the concrete placing surface 10
A method of transferring to a and then curing and hardening the concrete material 10 is also performed.

[0003]

However, in both of the above methods, when the concrete material 10 is in an uncured state,
Due to the breathing phenomenon of the concrete material 10, water and impurities in the concrete material 10 rise to the concrete surface layer portion, so that the surface material portion has a large amount of water and impurities, and the amount of cement in the concrete material 10 decreases. For this reason, there is a problem in that the surface layer portion is easily broken and the shape retention is poor, and the uneven patterns 11a and 12a are not accurately transferred by the roller 11 or the like. In addition, due to the breathing phenomenon, the uneven pattern 1 is formed by the roller 11 or the like.
There is a problem that traces of water bubbles remain on the portion of the concrete surface onto which 1a and 12a are transferred. Moreover, both of the above methods have a problem that it is difficult to transfer a natural stone tone pattern, and that only the uneven patterns 11a and 12a having small unevenness can be transferred.

The present invention has been made in view of the above circumstances, and it is possible to accurately decorate a concrete placing surface with a natural stone tone uneven pattern without being affected by the breathing phenomenon of the concrete material. The purpose is to provide a method of decorating a concrete surface that can be formed.

[0005]

In order to achieve the above object, a method for decorating a concrete surface of the present invention is
Prepare a connected body in which a plurality of cement pattern board materials having an uneven pattern formed on the surface are connected with a linear material with a predetermined gap,
The back surface of this connecting body is pressed against the surface of the uncured concrete that has been cast at a predetermined location, the concrete is then cured and hardened in that state, and the surface of the resulting hardened concrete is decorated with the cement pattern board material. .

[0006]

That is, in the method for decorating a concrete surface of the present invention, when moisture or impurities rise to the concrete surface layer due to the breathing phenomenon of the concrete material when the concrete is in an uncured state, the moisture and impurities are It escapes into a predetermined gap between the cement pattern board materials, and each cement pattern board material and the concrete placing surface come into close contact with each other. As a result, each cement pattern board material is integrated with the concrete surface when the concrete material is cured and hardened. Further, at this time, as compared with the method of laying out the individual cement pattern board materials one by one on the concrete placing surface, it is possible to lay out a large number of the cement pattern board materials in a short time. It is possible to completely eliminate the harmful effects of rising water content. And, since the concavo-convex pattern is formed on the concrete surface by each cement pattern board material that constitutes the above-mentioned connected body, the concrete surface is accurately decorated with the concavo-convex pattern such as natural stone tone, and the concavo-convex pattern is formed. No trace of blisters on the pattern. Moreover, it becomes possible to form an uneven pattern having large unevenness by selecting the cement pattern board material.

Next, the present invention will be described in detail.

According to the present invention, there is used a connecting body in which a plurality of cement pattern board members each having a concavo-convex pattern formed on the surface thereof are connected by a linear member with a predetermined gap.

Various cement materials are used as the cement material for the above-mentioned cement pattern board material, and preferably, ordinary mortar reinforced with glass fiber, carbon fiber or the like is used. On the surface of such a pattern board material,
By using pigment particles, stone particles, etc. at the time of forming the pattern board material, or by applying pigment or adhering stone particles to the uneven pattern surface formed on the pattern board material after molding,
It is conceivable to color-decorate a natural stone tone decorative pattern. Further, it is preferable that the specific gravity of the pattern board material is set to 2.0 to 2.2 to be a value smaller than the specific gravity of the concrete material of 2.3 to 2.4. In this case, when the pattern board material is laid on the concrete pouring surface, the pattern board material does not sink more than necessary into the concrete material.

Various materials may be used as the above-mentioned linear material, but a wire mesh, a metal rod, a metal lath (a small piece of metal), or the like is preferably used.
