Abstract

PURPOSE:To facilitate the peeling of a metallic sprayed deposit which is to be an outer layer at the time of refacing and to attain cost reduction as well as the shortening of working period by forming metallic sprayed deposit on the surface of a wall material for construction use into two layers so that each layer can be peeled off. CONSTITUTION:A heat resisting mortar layer 12 is formed on the surface of concrete 10. A film of buffer 14, such as heat resisting resin, is applied to the above layer 12, and further, a first metallic sprayed deposit 18 is formed on the above by using a thermal spray gun. Subsequently, after the buffer 14 is further applied to the first metallic sprayed deposit 18, a second metallic sprayed deposit 20 is formed on this buffer 14. By the above procedure, two layers consisting of metallic sprayed deposits 18, 20 mentioned above are formed on the concrete 10 surface, and the concrete 10 surface is faced with the second metallic sprayed deposit 20. At the time when the second metallic sprayed deposit 20 is deteriorated with the lapse of time and refacing is required, the second metallic sprayed deposit 20 is peeled off and the first metallic sprayed deposit 18 is allowed to appear. Then, this metallic sprayed deposit 18 becomes outer layer, and refacing is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for decorating the surface of an architectural wall material using a metal sprayed coating.

(Prior Art) There have been various methods for finishing the exterior or interior of architectural wall materials, but in recent years, for example, as disclosed in Japanese Patent Application Laid-Open No. 61117264, metal spray coating has been applied to the surface of architectural wall materials. There is a method of forming it to give it a metallic lustrous surface.

In this way, by creating a metallic glossy surface with a metallic sprayed coating, it is possible to apply a beautiful makeup with a profound feeling.

(Problem to be Solved by the Invention) However, in the conventional decorative method for architectural wall materials using a metal spray coating, since the metal spray coating is formed integrally with the architectural wall material, If the color tone of the surface of the metal sprayed coating changes and the gloss deteriorates, it becomes extremely difficult to redo the makeup.

In other words, in such cosmetic refurbishment, the old metal sprayed coating is removed uniformly over the entire surface, and a metal sprayed coating is applied again on top of the peeled off coating. It takes a lot of time and effort to
I can't offer it.

Incidentally, such a cosmetic method using a metal spray coating is disclosed in Japanese Unexamined Patent Publication No. 5
As disclosed in Japanese Patent Application No. 6-161150, there is a method of forming a multi-layer structure including a porous metal coating layer and a densified porous metal layer, but even in this method, only the porous metal coating layer and the densified porous metal layer The metal layer is formed integrally with a porous metal layer, and as with the conventional technique, it is difficult to peel off the metal layer, making cosmetic retouching extremely complicated.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a method for decorating architectural wall materials that allows for easy re-dressing of metal sprayed coatings.

(Means for Solving the Problems) In order to achieve the above object, the present invention forms a plurality of metal sprayed coatings on the surface of a building wall material in a multi-layered manner so that each layer can be peeled off, and this multi-layered metal sprayed coating An architectural wall material was once decorated with the outer layer of the metal spray coating, and after a period of time, the outer layer of the metal spray coating was peeled off to expose the lower layer.

Moreover, it is desirable to interpose a buffer material such as a heat-resistant resin between the multiple layers of metal spray coatings.

(Function) With the above-described structure, in the decorative method for architectural wall materials of the present invention, the metal sprayed coating is formed in multiple layers on the surface of the architectural wall materials so that each layer can be peeled off. The outer layer can be easily peeled off.

Then, when the outer layer deteriorates or after a certain period of time has passed, the outer cover is peeled off to expose the lower layer. Then, the newly exposed lower layer becomes beautiful because it has not deteriorated since it was previously covered with the outer layer. Therefore, the makeup of architectural wall materials can be refurbished by simply removing the outer layer.

If the lower layer and the outer layer are made of the same material, it is possible to restore the wall to the same atmosphere as when it was first built, whereas if they are made of different materials, a completely new atmosphere can be created. .

Further, by interposing a buffer material such as a heat-resistant resin between the multi-layered metal spray coating, peeling of the outer layer is made easier.

(Example) Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

1 to 6 are explanatory diagrams showing one embodiment of the decorative method for the surface of architectural wall materials according to the present invention, in which 1.
0 is the concrete that constitutes the building wall material.
As shown in the figure, the surface of this concrete 10 is subjected to surface treatment.

In the surface treatment, a heat-resistant mortar layer 12 is formed on the surface of the concrete 10.

Next, as shown in FIG. 2, the heat-resistant mortar layer 12
A coating of a buffer material 14 such as a heat-resistant resin is applied thereon, and a first metal spray coating 18 is formed on the buffer material 14 using a thermal spray gun 16 as shown in FIG. do.

The thermal spraying gun 16 performs spraying by heating powder particles of the metal to be thermally sprayed with a flame to melt them, and then fixing them to the surface of the heat-resistant mortar layer 12, as is conventionally done.

The first metal spray coating 18 thus formed
After a buffer layer 14 is further applied thereon as shown in FIG. 4, a second metal spray coating 20 is formed using a spray gun in the same manner.

Therefore, two layers of metal sprayed coatings 18 and 20 are formed on the surface of the concrete 10, and the surface of the concrete 10 is decorated with the second metal sprayed coating 20 serving as the outer layer.

The second metal sprayed coating 20 that has been applied to the surface of the concrete 10 in this way deteriorates over time and the surface changes color or loses its metallic luster. The second metal spray coating 20 is peeled off in this manner. This exposes the first metal spray coating 18,
Thereafter, the metal sprayed coating 18 becomes the outer layer, and the cosmetic retouching is completed.

In the decorative method for the surface of architectural wall materials according to the present embodiment, which is the method described above, the first and second metal sprayed coatings 18 and 20 are formed on the surface of the concrete 10, and the second metal sprayed layer serving as the outer layer is formed. 20, the surface of the concrete 10 is once decorated.

Then, when redoing makeup, the second metal spray coating 20 is applied.
This is done by removing it by polishing, stripping, etc.
Since the first metal sprayed coating 18 and the second metal sprayed coating 20 are laminated so that they can be peeled off from each other, the peeling operation of the second metal sprayed coating 20 can be significantly simplified.

Moreover, in this embodiment, in particular, the first. Since the buffer material 14 is interposed between the second metal spray coatings 18 and 20, the second metal spray coating 20 can be peeled off more easily.

Therefore, in this embodiment, since the second metal spray coating 20 can be easily peeled off, the work when refacing the surface of the architectural wall material is significantly facilitated, and the work period required for this can be shortened and costs can be reduced. achieved.

In addition, by simplifying makeup retouching in this way,
It is not limited to cosmetic retouching due to deterioration over time, but it is now easy to redo makeup systematically over a certain period of time, for example, every year. By forming the second metal sprayed coating layer 18, 20, it is possible to obtain a finished surface with a different color tone, and it is possible to perform a variety of cosmetics.

Furthermore, the metal spray coating layered on the concrete 10 is
It goes without saying that the number of layers is not limited to two, but may be three or more.

Furthermore, the first. Although the case where the buffer material 14 is interposed between the second metal spray coatings 18 and 20 has been disclosed, this buffer material 14 makes it easier for the second metal spray coating 20 to peel off. Although it is not necessary, even if each metal spray coating 18.20 is directly sprayed at intervals,
This allows for separation between the two.

Furthermore, in the above-mentioned embodiment in which cosmetic retouching is performed by simply peeling off the outer layer, the number of cosmetic retouchings is limited to the number of layers of the metal spray coating that has been formed in advance. Therefore, a new metal spray coating may be releasably applied when the bottom layer is exposed or after the outer layer is peeled off before that. In this way, makeup can be retouched semi-permanently.

(Effects of the Invention) As explained above, in the decorative method for the surface of architectural wall materials according to claim 1 of the present invention, a metal thermal spray coating is applied to the surface of architectural wall materials in multiple layers by making each layer releasable. This makes it extremely easy to peel off the metal sprayed coating that becomes the outer layer during cosmetic retouching, which in turn simplifies this cosmetic retouching process and shortens the required work period and reduces costs. I can do it.

In addition, by making makeup retouching easier in this way, it is possible to increase the number of makeup retouches, and by forming different metal spray coatings at predetermined intervals, it is possible to retouch makeup with a rich variety of color tones. becomes.

Furthermore, in claim 2 of the present invention, since a buffer material such as a heat-resistant resin is interposed between the multi-layered metal sprayed coating, the outer layer of the metal sprayed coating can be peeled off more easily. It has a great effect.
