DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior and exterior finishing method for buildings.

[0002]

2. Description of the Related Art In recent years, reinforced concrete construction (RC construction)
There is a construction method of finishing with tiles as an interior and exterior finish of a building represented by steel or reinforced concrete (SRC).

[0003] In the finishing method, a tile is previously attached to a formwork surface, and the tile is cut into the concrete surface at the time of concrete casting, or a tile is applied to the surface of a precast (PC) plate manufactured at a factory. There is a tile driving method in which tiles are driven, or a method in which concrete is cast and tiles are attached to the concrete surface from which the mold has been removed using mortar or the like.

The last of these methods is still widely used at present.

In this method, a mortar or the like is applied to the concrete surface to form a tile base, on which tiles are further adhered using a mortar or the like.

However, in this method, the concrete surface is smooth at the bonding interface between the concrete surface and the tile base, so that the mortar does not penetrate into the concrete, or there is a cement product (Efro) on the concrete surface. As a result, the adhesion of the mortar was sometimes incomplete.

[0007] In addition, the behavior of the temperature change of the building frame due to the season, earthquakes and other vibrations often occur, and even if it adheres in the initial stage, it is liable to peel off with aging, and the exterior finishing material may fall due to fall. There was danger to people.

From this, various improvements have been made.
In recent years, as shown in FIGS. 8 to 10, after casting concrete 50, mortar 54 is applied to the surface of concrete 50 from which the mold has been removed, thereby forming a foundation for sticking tile 56. Furthermore, in order to strengthen the adhesion between the surface of the concrete 50 and the mortar 54, a polymer 58 (SBR, PAE, EVE) is provided in the mortar 54.
Etc.), or a method of applying the polymer mortar 60 after directly applying the polymer 58 diluted several times to the surface of the concrete 50.

[0009]

However, peeling has not been completely eliminated by these methods.

[0010] The reason why the peeling does not disappear is because the types of the polymer 60 and the polymer manufacturers are various, and the usage methods are different from each other.
For this reason, mishandling, easy use, or the state of change of the polymer after aging is not clear.

Thus, the present invention has been made to solve the above-mentioned conventional problems, and is intended to prevent a problem such as peeling of tile pieces due to aging and a concrete body which does not cause harm to human body and the like. It is an object of the present invention to provide a surface treatment method and a surface treatment part thereof.

[0012]

In order to achieve the above object, the present invention is configured as shown in FIGS.

[0013] The present invention relates to an interior and exterior finishing method for a building in which tiles are adhered to a concrete surface from which a mold has been removed and a mortar or the like is used as the interior or exterior finish of the building. On the inner surface of the mold 10, an adhesive sheet 16 made of a fiber sheet having a large number of holes is attached, the front and back surfaces of which are configured as cilia-shaped protrusions 12 and 14, respectively. Concrete 1
8, after the concrete 18 is solidified, the one-side ciliary protrusion 14 of the adhesive sheet 16 is fixed to the concrete 18, and the adhesive sheet 16 is left on the concrete 18 to form the formwork 10. The cilia-shaped protrusion 1 on the other side of the adhesive sheet 16 which has been released from the mold and exposed to the outside
2 is characterized in that an exterior finishing material 22 composed of a plurality of tile pieces is attached via an adhesive 20.

[0014]

According to the present invention, in order to avoid the smoothness of the mold release surface of the formwork 10 in the cast concrete 18, the adhesive sheet 16 made of, for example, a porous fiber sheet or the like is simultaneously cast into the concrete 18. After the mold 10 is released from the mold, the cilia-shaped protrusions of the adhesive sheet 16 such as the porous fiber sheet appear on the surface of the concrete 18.

Thereafter, the tiles are bonded via the adhesive 20.

According to such a construction method, the adhesive 20 such as polymer mortar for the foundation of the tile is anchored by the cilia-like protruding fibers of the adhesive sheet 16 such as a porous fiber sheet, and the concrete surface is conventionally fixed. Due to the above bonding, the risk of peeling is reduced.

Further, even if the aging occurs, the exterior finishing material such as tiles attached by the anchor effect by the ciliary projecting fibers (ciliform projections) of the adhesive sheet 16 does not drop.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a mold, and an adhesive sheet 16 made of, for example, a porous fiber sheet is provided inside the mold.

The adhesive sheet 16 has cilia-shaped protrusions 12 and 14 on the front and back surfaces, respectively.

Further, it is preferable that a plurality of small holes are formed in the adhesive sheet 16.

The adhesive sheet 16 is attached to the inside of the mold 10 with a staple or the like (see FIGS. 1 and 2).

Thereafter, the concrete 18 is cast. Then, as shown in FIG. 3, the mold 10 is released after the concrete 18 is solidified.

At this time, since the adhesive sheet 16 is simply attached to the formwork 10 with a staple or the like,
It can be easily left on the solidified concrete 18 side.

Then, as shown in FIG. 4, an exterior finishing base is formed with an adhesive 20 such as polymer mortar or mortar, and an exterior finishing material 22 such as a tile may be attached.

There are various methods for applying the exterior finishing material 22, and the method is not limited at all.

As described above, in the present embodiment, in addition to the chemical bonding effect of the cement material or the like, the bonding effect due to the shape (anchor effect due to the cilia-shaped protrusion) can be expected, so that the tile peeling can be effectively prevented. Therefore, human harm caused by peeling or the like can be effectively prevented.

The concrete surface treatment method for maintaining good adhesion between the concrete surface (body surface) and the exterior finishing material requires tile work, plastering work,
It can be used in construction fields such as painting.

[0029]

The present invention has the above configuration.

According to the present invention, the mortar can be physically and firmly bonded without roughening the concrete surface.

Furthermore, since concrete is poured with an adhesive sheet such as a porous fiber sheet interposed on the formwork surface, excess water in the concrete can be drained, and as a result, the concrete surface strength is greatly improved. There is also an effect.

Further, since an adhesive sheet such as a porous fiber sheet is left on the concrete surface, there is also an effect that it is not necessary to treat it as industrial waste.
