DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fine-grained inorganic aggregate-attached sheet, a method for finishing a concrete surface using the same, and a decorative panel, and more particularly to a dam, a concrete retaining wall, a wall surface of a building structure, and a floor. Fine-grained inorganic aggregate-attached sheet that can be easily and firmly applied as a decorative finish on concrete surfaces such as surfaces, columns, walls, etc. and secondary concrete products, resin concrete products, etc., and a concrete surface finishing method using the same; Related to decorative boards.

[0002]

2. Description of the Related Art Conventionally, in order to beautifully decorate the surface of a concrete structure and increase waterproofness, it is general to apply various cosmetics to the inner wall, outer wall or floor of a building.

[0003] One example is a conventional inner wall at a construction site,
When constructing exterior walls and floors, skilled workers apply mortar, etc. on the site, then finish processing, paint with paint, paste natural stones or apply tiles, etc. In the case of a building, panels that have been subjected to interior / exterior finishing in a factory have been laid on the interior / exterior or the like.
In addition, it has been used in various ways such as finishing a metal plate or a glass plate.

However, when the outer wall, the inner wall and the floor surface are constructed in a stone-applied tone, it is necessary to attach natural stones by pulling with a copper wire or a steel wire or finishing by means such as washing out. With metal plates, two-color or three-color stone blow, etc., skilled workers are required for this finishing process, and there is a problem that it is difficult to make the joints the desired color and finish. Due to its nature, it was not possible to work on rainy days, and there was also a problem that was affected by the weather. Also,
After finishing the panel in the factory in advance, when the panel is carried to the site and the outer wall is constructed, the above-mentioned problem is eliminated, but when the panel is transported from the factory to the site or constructed at the site, the finished outer surface There was a problem that scratches and dirt tended to be formed.

Therefore, as disclosed in Japanese Patent Publication No. 7-106616, a resin film, a surface layer formed of an inorganic aggregate and a binder formed on the film, and a surface layer provided on the surface layer are provided. Consisting of a ceramic coating layer, during transport, during construction, the film serves as a protective layer, and after construction as a panel, it is possible to obtain a surface layer composed of the inorganic aggregate by peeling the film. Stone paper that can be provided has been provided. And as a method of using this stone paper, mortar, concrete,
It is mentioned that a panel is formed by providing a resin, asbestos, or the like as a reinforcing material, or a block is manufactured.

[0006]

However, panels and blocks are manufactured using stone paper, transported to the site, and installed on the outer wall using mortar. This is the same as tiled and bricked construction. Here, the work that requires the most skill during the application of tiles and bricks is to leave no air bubbles between the mortar layer applied to the ground surface and the exterior material such as tiles. The material is insufficient in fixing strength and peels off due to vibrations caused by vehicle traffic or earthquakes. In addition, dew condensation occurs on this portion, and in a cold region, a problem such as freezing occurs. This construction problem also exists in panels and blocks manufactured using stone paper.

Here, a construction method in which mortar is applied to the lower ground of an outer wall or the like and the ceramic coating layer of the stone paper is directly fixed on the mortar layer is also considered. Even if it is used as it is for the direct pasting method, it is difficult to complete the construction. That is, the above-mentioned stone paper applies a binder on a resin film, and before the binder is cured, scatters the aggregate on the binder in a plurality of times in order from the aggregate having a large particle size, and then forms a ceramic coating thereon. Is sprayed to form a ceramic coating layer, so that the surface of the ceramic coating layer is very rough and has low air permeability, and when mortar is provided on this ceramic coating layer to manufacture a block or panel, It is possible to avoid leaving air bubbles between the mortar and the ceramic coating layer by shaking or vacuum drying when applying or applying the mortar. The air in the center does not move to the side even if it is pressed, but remains inside, and swells or peels off due to the above-mentioned temporal changes such as vibration, condensation, and freezing. This is because having a durability problem is. In particular, this problem is remarkable when stone paper having a large area is used in consideration of construction efficiency. For the same reason, the method of attaching a sheet formed of a stone and a binder to a wall surface was initially applied to an outer wall, but is now mainly for the interior.

In view of the above situation, the present invention is intended to solve the problem by attaching an inorganic aggregate to one surface of a film with a binder and applying cement mortar, resin mortar or cement paste or the like to the concrete surface. This is a fine-grained inorganic aggregate-attached sheet used in the direct bonding method that exposes the surface layer made of inorganic aggregate by peeling the film after construction, and no air bubbles remain with the mortar layer at the time of construction An object of the present invention is to provide a fine-grained inorganic aggregate-attached sheet capable of improving the properties and durability, a method for finishing a concrete surface using the same, and a decorative board.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a preferred embodiment of the present invention. FIG. 1 shows a fine-grained inorganic aggregate-attached sheet 1 according to the present invention, and FIGS.
FIG. 4 shows a method of finishing the concrete surface using the fine-grained inorganic aggregate-attached sheet 1 according to the present invention, and FIGS. 5 and 6 show various modes of finishing.

FIG. 1 shows a fine-grained inorganic aggregate-attached sheet 1 according to the present invention. The fine-grained inorganic aggregate-attached sheet 1 shown in FIG. 1A is obtained by adhering a fine inorganic aggregate 3 to one surface of a film 2 by bonding with a binder 4.
The fine-grained inorganic aggregate-attached sheet 1 shown in (1) is obtained by applying a release agent 5 on one surface of a film 2 and adhering the fine inorganic aggregate 3 with a binder 4 thereon as described above.
In the fine-grained inorganic aggregate-attached sheet 1 shown in FIG. 1 (c), a pattern 5A having a thickness of 3 to 10 μm is formed on one surface of a film 2 by gravure printing, and the fine inorganic aggregate 3 as described above is further formed thereon. It is bonded and attached with a binder 4. The pattern 5A formed by gravure printing includes marble,
There are various patterns such as a natural stone pattern such as granite and sandstone, a tile pattern, and a wood grain pattern, and an exquisite combination of these free printed patterns and the inorganic aggregate 3 can be finished. Further, the inorganic aggregate 3 may be completely covered by the gravure printed pattern 5A, or the inorganic aggregate 3 may be partially exposed from between the patterns 5A.

Here, on the side of the fine-grained inorganic aggregate-attached sheet 1 on which the inorganic aggregates 3 are attached, a large number of inorganic aggregates 3 protrude randomly, and continuous voids 6 are formed therebetween. The air permeability is provided in the direction along the sheet 1 and in the direction penetrating the layer of the inorganic aggregate 3. Also,
The film 2 is peeled off after the surface of the fine-grained inorganic aggregate-attached sheet 1 to which the inorganic aggregate 3 is attached is fixed to the concrete surface, and has good releasability with the binder 4. In addition, it is necessary that the adhesive be appropriately adhered until peeling.

The film 2 has a thickness of 0.025 to
A 0.1 mm synthetic resin film or coated paper is used. As the synthetic resin film, polyethylene terephthalate (PET), vinyl chloride resin, polypropylene, or the like is used.

It is preferable that the film 2 has a release agent 5 applied to the surface to which the inorganic aggregate 3 is to be attached, and that the release agent 5 has a grain of marble, sandstone, travertine or the like.
It is also preferable to use a gravure-printed grain or tile pattern. These printed patterns are in film 2
When it is peeled off, it remains on the surface of the finished surface and serves to enhance decorativeness. In the case of the gravure printing, the stone tone contributes to the decorative property as a ground color on the surface of the inorganic aggregate layer, but in the case of wood grain and the like, the concealing power is large, so that it contributes to the transfer of the printing ink.

The inorganic aggregate 3 is made of natural stone, colored stone, ceramic or alumina oxide having a particle size of 2 mm or less, preferably 0.1 to 1.0 mm. As the natural stone, silica sand, cold water stone, granite, and others are used. As the colored stone, one obtained by applying an acrylic color, baking a porcelain tile glaze, coloring a lithium silicate, or the like to a raw stone such as silica sand or calcite or cold water stone is used. Ceramic and alumina oxide are mainly used for floors.

The binder 4 may be made of an emulsion of acrylic resin (AC), ethylene vinyl acetate (EVA), acrylic silicon or the like, or an epoxy resin, polymethyl methacrylate (PMMA), unsaturated polyester (particularly, soft polyester). Among them, a thermosetting resin with less discoloration is used among polyurethane and the like.

Then, the fine-grained inorganic aggregate-attached sheet 1 according to the present invention is manufactured as described below. First, as shown in FIG. 2, the first manufacturing method places the film 2 on a flat base and places the binder 4 and the inorganic aggregate 3 thereon at a ratio of 1: 3 to 1: 6 ( Weight ratio),
Spray or spray to a thickness of 0.5 to 10 mm.

Next, in the second manufacturing method, as shown in FIG. 3, the film 2 is placed on a flat base and the film 2 is placed thereon.
The binder 4 was applied at a rate of 00 to 400 g / m ² (see FIG. 3A), and then the inorganic aggregate 3 was sprayed (see FIG. 3).
(See (b)), 100-200 g /
Spray additional binder 4 at a rate of m ² (FIG. 3 (c)
). Also in this case, the amount of application is adjusted so that the entire thickness is 0.5 to 10 mm.

Here, since the binder 4 is an emulsion, the volume shrinks during drying and curing, so that the voids 6 are always formed between the inorganic aggregates 3, so that the binder 4 has air permeability. In addition, in the binder 4 of 200 to 400 g / m ² ,
Since the aggregate having a particle diameter of 1 mm or more does not connect with each other, the particle diameter of the inorganic aggregate 3 is set to 0.1 to 1.0 mm in the present invention.

In any of the manufacturing methods, the inorganic aggregate 3
It is important to adjust the viscosity and the mixing ratio of the inorganic aggregate 3 so that the space between the inorganic aggregates 3 is not buried with the binder 4 so that the air gap 6 having air permeability is formed on the surface side. It is also important that the surface side of the inorganic aggregate 3 is not evenly leveled. Also, if the particle size of the inorganic aggregates 3 varies, the small inorganic aggregates 3 are buried between the large inorganic aggregates 3 and the desired voids 6 may not be formed. It is preferable that the particle sizes of the inorganic aggregates 3 are uniform as much as possible, but they do not necessarily have to be uniform.

As the product form of the fine-grained inorganic aggregate-attached sheet 1 manufactured in this way, there are a long form having a predetermined width and a roll-like form, and a cut form having a predetermined size and shape. . The long roll is cut into a desired size and used at a construction site. When cutting into a predetermined size shape in advance, for example, 30 cm × 50 cm or 45 c
Golden section like mx 73cm, then 3 like the latter
It is desirable to be able to construct a unit area with a fixed number of sheets, such as 1 m ² per sheet. The shape of the fine-grained inorganic aggregate-attached sheet 1 according to the present invention is not limited to a rectangle or a square, but may be any shape.

Next, a method for finishing a concrete surface using the fine-grained inorganic aggregate-attached sheet 1 will be described with reference to FIG. The concrete surface may be a concrete casting surface or a surface on which concrete blocks are stacked, and can be widely applied regardless of a wall surface, a floor surface, or a ceiling surface.

First, a primer 8 prepared by diluting a 50% strength resin emulsion with twice the amount of water was applied to the concrete surface 7.
Is applied at a rate of 100 to 300 g / m ² to form a base (see FIG. 4A). The purpose of applying the primer 8 to the concrete surface 7 is to stop the water so that the moisture of the cement cement mortar 9 to be applied later will not be rapidly absorbed by the foundation, and to fix dust and the like. However, the concave and convex concrete surface 7 is filled with the resin cement mortar. Next, an adhesive compound is blended with a cement paste having an appropriate softness made by mixing cement and water, and a resin emulsion containing a thickener or a single fiber is mixed at about 10 to 20% by weight (concentration 50%). Then, the cement mortar 9 for bonding made by adding water and mixing is applied to the base surface with a thickness of 2 to 4 mm, and the material is rubbed on average with a comb (see FIG. 4 (b)). Here, the resin cement paste does not slump even when applied to an upright surface. The cement itself has a structural viscosity, and promotes this by adding Metrolose (MC) or the like. Further, whitening after finishing can be prevented by reducing the water ratio to cement. Next, the fine-grained inorganic aggregate-attached sheet 1 having an appropriate size and shape is
Based on the measured black ink, it is attached to the cement cement mortar 9 from the side of the inorganic aggregate 3 (see FIG. 4 (c)). in this case,
Between adjacent fine-grained inorganic aggregate-attached sheets 1 and 1, there are provided predetermined intervals serving as joints described later. In this case, a blind spot or a free joint width may be taken, or a blind spot in which the joint is a single line may be used. Then, the surface of the fine-grained inorganic aggregate-attached sheet 1 is gently pushed from the center side to the edge side with a trowel or a roll to expel air using the voids 6 and partially remove the cement mortar 9 for bonding out of the sheet. Protrude (see Fig. 4 (d)). At this time, the entire surface of the fine-grained inorganic aggregate-attached sheet 1 is lightly beaten up with a plate having a large area. This plate may be, for example, one in which a sponge is attached to one surface of a veneer plate having a thickness of 12 mm and a handle is attached to the other surface. Then, the cement cement mortar 9 protruding between the fine-grained inorganic aggregate-attached sheets 1 and 1 is removed with a sponge spatula to form joints 10 (see FIG. 4E). After curing for one day in the summer and two days in the winter, a paint of a desired color is applied to the joint portion 10, and the film 2 is peeled off and removed (see FIG. 4 (f)). In addition, it may be left to cure for about 30 days. In this case, the edge of the joint portion 10 appears sharp. The layer composed of the inorganic aggregate 3 and the binder 4 has a property of breathability due to the presence of the voids 6, so that moisture is condensed between the inorganic aggregate layer and the film 2 to reduce the adhesive strength, or Since the agent is water-based, water is coagulated on the film surface, the emulsion is re-emulsified, and the film 2 is very easily peeled. Finally, acrylic urethane or silicon, lithium silicate, clear top or the like is applied on the entire surface as a top coat 11 to finish (see FIG. 4 (g)).

There are various modes of attaching the fine-grained inorganic aggregate-attached sheets 1 to the concrete surface 7. For example, as shown in FIG. 5 (a), a typical method is to apply a rectangular fine-grained inorganic aggregate-attached sheet 1 in a brick-stacked shape and to uniformly apply the entire surface. In this case, the interval between the joint portions 10 can be freely set. As a modified example, as shown in FIG. 5 (b), there is a different-color application in which two or more fine-grained inorganic aggregate-attached sheets 1,... . Here, the fine-grained inorganic aggregate-attached sheets 1 of different colors are indicated by oblique lines. Further, as a modified example of FIG.
(c) is a cut-and-paste method in which rectangular and square fine-grained inorganic aggregate-attached sheets 1, ... cut in various dimensions are combined and pasted. Further, as a modified example, FIG.
Are cut and affixed sheets having various sizes of irregularly shaped fine-grained inorganic aggregate-attached sheets 1,... Cut like a broken stone.
Here, the sheets 1,... May have the same color or pattern or may have different colors. Also, the fine-grained inorganic aggregate-attached sheet 1 does not necessarily need to be applied to the entire surface of the concrete surface, but is attached to various places with accent colors as shown in FIG. After applying the resin or various paints to the space to be removed, and removing the film 2, the finish intended by the designer is expressed. here,
Various paints are acrylic resin, spray tile, spray of stone, fluorine resin or silicone resin.

Further, as shown in FIG. 6 (a), when the cement mortar 9 for bonding is semi-hardened, the fine-grain inorganic aggregate-attached sheet 1
There is an uneven finish in which unevenness is formed by changing the pressing force irregularly or regularly from the side. Further, as shown in FIG. 6B, there is a joint finish in which the joint portion 10 has a square cross section.

When the concrete surface 7 has a corner 12 as shown in FIG.
In order to finish the concrete surface 7 including the above with the continuous fine-grained inorganic aggregate-attached sheet 1, the film 2 corresponding to the corner portion 12 is cut (cut portion 13) as shown in FIG. As shown in FIG. 7B, the inorganic aggregate 3 and the binder 4 corresponding to the corners 12 are removed (removal part 14).
Then, the cutting portion 13 or the removing portion 14 is arranged along the corner portion 12, and the inorganic aggregate 3 is fixed via the cement cement mortar 9 in the same manner as described above. After the cement mortar 9 for bonding is sufficiently cured, the film 2 is peeled off in the same manner as described above.

The present invention is used for finishing a concrete surface. In the above-described embodiment, an example of a method for finishing an existing concrete surface has been described. Good things can be easily guessed. That is, the outer wall of the wooden mortar-painted house is fixed with a reinforcing material such as wire mesh on the surface of the structural plywood,
Mortar is applied thereon, and the surface is further sprayed with paint, sprayed with colored mortar, or tiled to finish the surface. Therefore, instead of these surface finishes, the above-mentioned fine-grain inorganic aggregate-attached sheet 1 is in a state in which the underlying mortar is in an uncured state or has been cured, and is then coated with the cement cement mortar 9 as described above. It is possible to stick with.

[0032]

According to the fine-grained inorganic aggregate-attached sheet of the present invention and the concrete surface finishing method using the same as described above, the fine-grained inorganic aggregate-attached sheet is placed on the mortar applied to the concrete surface. At the time of construction to paste, to form a continuous gap between the inorganic aggregate on the surface side to which the inorganic aggregate is attached,
Since air permeability is provided in the direction along the sheet, even if air bubbles are taken in between the sheet and the mortar layer, it can be easily pushed out lightly from the surface side of the sheet to expel air to the side. In addition to the improvement in the properties, the absence of air bubbles and the penetration of mortar into the voids increase the fixing strength and can increase the durability. Furthermore, since the sheet of the present invention is integrated with a base such as a base mortar and concrete, and after the film is peeled off, the water of the base passes through the surface layer composed of the inorganic aggregate and the binder, so that excess water can be removed quickly. The curing of the underlying mortar is fast, and the underlying mortar is hard to crack and hardened.

Even if the mortar displaced from between the fine-grained inorganic aggregate-attached sheets attached at predetermined intervals adheres to the film, the excess mortar is removed to form joints, and then the film is peeled off. Thereby, the surface layer made of the inorganic aggregate can be exposed in a beautiful state, and the edge of the joint can be sharply formed, so that the finish is extremely good.

Further, it should be noted that since the inorganic aggregate forming layer has air permeability, it can be integrated with the foundation concrete or mortar layer and can transmit moisture of the frame, so that extra dew condensation can be generated in the room. And there is no fear of freezing outside. Also,
Natural stone finishing and tile finishing that are different from conventional stone spraying can be easily performed.
