DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, the following method has been used to provide a decoration made of a natural stone-like uneven pattern on a concrete surface. That is, as shown in FIG. 14, a roller 11 having a natural stone-like uneven pattern 11a formed on the surface of a concrete casting surface 10a (in an uncured state) is rolled, and the uneven pattern 11a of the roller 11 is removed. This is a method in which the concrete material 10 is transferred to the concrete casting surface 10a and then cured and hardened. Separately from this method, as shown in FIG.
0a is pressed by a board 12 (or a sheet or the like) having a natural stone-like uneven pattern 12a formed on the lower surface, and the uneven pattern 12a of the board 12 is placed on a concrete casting surface 10
a, and then the concrete material 10 is cured and hardened.

[0003]

However, in the above two methods, when the concrete material 10 is in an uncured state,
Due to the breathing phenomenon of the concrete material 10, the moisture and impurities in the concrete material 10 rise to the surface layer of the concrete. Therefore, the amount of moisture and impurities in this surface layer is large, and the amount of cement in the concrete material 10 is small. For this reason, there is a problem that the surface layer portion easily collapses and is inferior in shape retention, and the transfer of the uneven patterns 11a and 12a by the roller 11 or the like is not performed accurately. Also, due to the above-mentioned breathing phenomenon, the uneven pattern 1
There is a problem in that traces of water bubbles remain on the portion of the concrete surface where 1a and 12a have been transferred. In addition, both methods have a problem that it is difficult to transfer a natural stone pattern and a problem that only the uneven patterns 11a and 12a having small unevenness can be transferred.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and it is an object of the present invention to accurately decorate a concrete casting surface with a natural stone-like irregular pattern without being affected by the breathing phenomenon of a concrete material. It is an object of the present invention to provide a method for decorating a concrete surface which can be made.

[0005]

To achieve the above object, a method for decorating a concrete surface according to the present invention comprises:
Preparing a connected body in which a plurality of cement-made pattern plate materials having an uneven pattern formed on the surface are connected with a linear material at predetermined intervals,
The specific gravity of each of the above cement pattern boards is set to 2.0 to 2.2.
Fixed, the back surface of the connected body is pressed against the uncured concrete surface cast in place, the concrete is cured and cured in that state, and the resulting hardened concrete surface is decorated with the cement pattern board , For the production of the above-mentioned linked body
A plurality of recesses are formed on the surface with the predetermined gap
The plurality of recesses are transferred by using
When it becomes irregular pattern of the plural cement pattern board material
The cement material is poured into the plurality of recesses formed in the shape
Wire to this cement material
Buried and the solidification of the cement material
Are connected by a linear material .

[0006]

In other words, in the method for decorating a concrete surface according to the present invention, even when moisture and impurities rise to the surface layer of the concrete due to the bleeding phenomenon of the concrete material when the concrete is in an unhardened state, the moisture and impurities are removed by a plurality of pieces. Escape to a predetermined gap between the cement pattern boards, and each cement pattern board and the concrete casting surface come into close contact. Thereby, at the time of curing and hardening of the concrete material, the respective cement-made pattern boards are integrated with the concrete surface. Also, at this time, compared with the method of laying out one piece of the cement pattern board alone on the concrete casting surface, it is possible to lay a lot of cement pattern boards in a short time, so that the breathing phenomenon is caused. The adverse effects of an increase in moisture and the like can be completely eliminated. And, on the concrete surface, since an uneven pattern is formed by each cement pattern plate material constituting the connecting body, the concrete surface is accurately decorated with the uneven pattern such as natural stone tone, and the irregularities are formed. There are no blemishes on the pattern. In addition, by selecting a pattern plate made of cement, it is possible to form an uneven pattern having large unevenness.

Next, the present invention will be described in detail.

According to the present invention, there is used a connected body in which a plurality of cement-made pattern boards having an uneven pattern formed on the surface are connected by a linear material with a predetermined gap.

Various cement materials are used as the cement material of the above-mentioned pattern board made of cement. Preferably, ordinary mortar reinforced with glass fiber, carbon fiber or the like is used. On the surface of such a pattern board,
By using pigment particles, stone particles, etc. at the time of forming the pattern board material, or by applying pigment or bonding the stone particles to the uneven pattern surface formed on the pattern board material after molding,
It is conceivable to express natural stone tone decorative patterns in color. In addition, the specific gravity of the pattern plate material is set to 2.0 to 2.2, and the specific gravity of the concrete material is set to a value smaller than 2.3 to 2.4.
You are. In this case, when the pattern plate is laid on the concrete casting surface, the pattern plate does not sink more than necessary in the concrete material.

As the linear material, various materials are used, and preferably, a wire mesh, a metal rod, a metal lath (a small piece of metal) or the like is used.
