DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described more specifically with reference to embodiments. FIG. 1 is an exploded perspective view showing a building wall covering according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view thereof (however, a net is omitted).

As shown in FIGS. 1 and 2, the building wall covering 10 is a square base 12, a spray-painted body 13 spray-painted on the base 12, a base 12 and the spray-painted body. 13 and a net 14 interposed therebetween. Here, the base 12 has a plurality of round holes 12.
a, and a plurality of round holes 12 a are arranged in a matrix parallel to the vertical and horizontal sides of the base 12. In addition, the arrangement state of the plurality of round holes 12a is not necessarily limited to a matrix, and can be appropriately selected.

As the base 12, a metal base, a cement base, or a resin base is used. Examples of the metal base include an aluminum plate, a steel plate, and an iron plate. The cement-based base is made by mixing a cement-based inorganic substance such as cement or calcium silicate with a filler such as carbon fiber or polypropylene fiber, strengthening the resultant, and compressing it under high pressure, and includes a calcium silicate plate, a flexible plate and the like. The resin base is formed by hardening a glass fiber, carbon fiber fabric or the like with a resin.

As will be described later, the round hole 12a of the base 12 is for inserting a water-resistant epoxy 28 (see FIGS. 6 and 8) as an adhesive to increase the adhesive strength by an anchor effect.

The net 14 is for preventing the spray-painted body 13 spray-painted on the base 12 from entering the round hole 12a. The net 14 is preferably made of perishable fiber, and more preferably, the perishable fiber is glass fiber or synthetic fiber.

The net 14 is not always required as long as the round hole 12a of the base 12 is not completely clogged by the spray coating 13 and the anchor effect can be exhibited. What is interposed between the base 12 and the spray coating 13 is not necessarily limited to the net, and may be, for example, a nonwoven fabric.

The material of the spray-coated body 13 was prepared by mixing the following components. (1) Ceramic aggregate 61.60 parts by weight (2) Acrylic emulsion (solid content 50%) 25.20 parts by weight (3) Thickener (hydroxymethylcellulose) 11.35 parts by weight (4) pH adjuster (Ammonia water) 0.17 parts by weight (5) Antifoaming agent (alcohol) 0.03 parts by weight (6) Film forming aid (alcohol) 0.39 parts by weight (7) Water 1.26 parts by weight Work Thickeners, pH adjusters, defoamers, film-forming auxiliaries, etc. are mixed in for the sake of ease and storage convenience, but are not essential components of the present invention. Here, the film-forming auxiliary is for lowering the temperature of the transparent film-forming of the emulsion.

The synthetic resin is not limited to an acrylic emulsion, and other epoxy-based or urethane-based emulsion-based synthetic resins can also be used.
Here, a ceramic aggregate is used as an aggregate, but a natural stone aggregate or a baked aggregate may be used in addition to the ceramic aggregate.

The ceramic aggregate is prepared by mixing clay with an inorganic pigment having an appropriate color, such as iron oxide or zinc oxide.
It is fired at 200 to 1400 ° C. to form a ceramic, which is pulverized. As the natural stone aggregate, one obtained by crushing and classifying natural stone is used as it is. For white, quartz sand, marble granules, cold water stone, and the like are used, and for black, Mino black and the like are used. The baked aggregate is made of natural stone granules (usually silica sand is often used, followed by hydrated stone), inorganic pigments (usually metal oxides, titanium oxide as white, yellow (For example, titanium yellow, cobalt as blue, chromium as green, carbon as black)) and baking at 800 to 1000 ° C. on the surface of natural stone. Most of the aggregate actually used is this baked aggregate.

The particle size distribution of the aggregate can be freely selected depending on the expression of the pattern of the spray-coated body 13. From the strength and appearance, the following particle size distribution is employed. That is, In this case, when mica is sprayed on the sprayed surface, a spray-painted body 13 having a very beautiful appearance that is not different from a so-called naturally occurring granite can be obtained. When the mica was sprayed on the sprayed surface, a mixture prepared with the following components was used. That is, (1) 6.00 parts by weight of mica (2) 62.00 parts by weight of binder (3) 32.00 parts by weight of water Here, the binder is the above-mentioned acrylic emulsion (solid content 50%), It is a mixture of a viscosity agent (hydroxymethylcellulose), a pH adjuster (aqueous ammonia), an antifoaming agent (alcohol-based), and a film-forming auxiliary (alcohol-based), and the blending amount is the same as described above. The size (average diameter) of the mica is 0.2 because the mica can be studded in the concave portion on the spraying surface.
~ 5.0 mm is desirable. The average diameter is the maximum diameter in the case of not being a perfect circle, and the maximum length of each side in the case of a quadrangle.

In the building wall covering 10 of the present embodiment, as the material of the spray-painted body 13, ceramics having the above-mentioned components and three colors (white, gray, black) are used. First to third spraying materials 7, 8, 9 are used. The first to third spraying materials 7, 8, 9 are applied in an uneven shape and in a non-mixed multicolored shape. Here, the non-mixed multicolored state means that the first to third spraying materials 7, 8, 9
This is a state where the colors are applied so that they do not mix with each other. As a result, the color does not become uniform, so that the color approaches that of a natural stone having a sparse pattern. Further, as described above, scales of mica are studded in the concave portions of the spray coating body 13. Thus, the first to third spraying materials 7,
8 and 9 are applied in uneven and non-mixed multicolored form, and the mica scales are studded in the recesses, so that the building wall has a very beautiful appearance that is not different from naturally occurring granite The package 10 is realized.

Hereinafter, a method for manufacturing the above-described building wall covering will be described. FIG. 3 is a perspective view showing a three-head spray gun used for painting the building wall covering.

As shown in FIG. 3, the three-head spray gun is provided with three tanks 1, 2, and 3, and each of the tanks 1, 2, and 3 has first to third sprays having different colors. Timber 7,
8 and 9 can be stored separately. The tanks 1, 2, and 3 are provided with jet nozzles 4, 5, and 6, respectively, to compress the first to third spraying materials 7, 8, and 9 in the tanks 1, 2, and 3, respectively. The air can be ejected from the ejection nozzles 4, 5, and 6 by air. Jet nozzle 4,
The diameters of 5 and 6 are 12 mm, 10 mm and 6 mm, respectively, and the discharge ratio of the first spray material (white) 7, the second spray material (gray) 8 and the third spray material (black) 9 is 5 : 4: 1. The angles of the ejection nozzles 4, 5, and 6 are adjusted so as to be substantially concentrated at one point. If it is actually concentrated exactly on one point, the first to third spraying materials 7, 8, 9 are mixed or laminated to form one color. It becomes difficult to apply in an unmixed multicolored form. However, in practice, even if the focus is exactly the same, since a person holds and applies the three-head spray gun in hand, the distance and angle to the outer wall and the like are shifted, so that there is not much problem. The spray gun is provided with a switch (not shown) for switching the compressed air from a high pressure state (4 atm) to a low pressure state (2 atm) (and from a low pressure state to a high pressure state).

First, on a base material made of calcium silicate having a thickness of 4 mm, which is cut into the bases 12 (see FIGS. 1 and 2) in a post-process, the first color having different colors is used by using a three-head spray gun. -The third spraying material 7, 8, 9 was applied with a thickness of about 2 to 3 mm (lower blowing). Then, the three-head spray gun was switched from the high pressure state to the low pressure state, and the first to third spraying materials 7, 8, and 9 were applied again with a thickness of about 1.0 to 1.5 mm (patterning). As a result, the first to third spraying materials 7, 8, and 9 were applied in a non-mixed multicolored form, and an uneven pattern was formed. Next, on the surfaces of the first to third spraying materials 7, 8, and 9 which are applied in an uneven and non-mixed multicolored shape, using a ricin gun having a diameter of 5 to 6 mm, a synthetic resin (acrylic emulsion) is used. After spraying the mixed mica, the sprayed surface was polished at a polishing rate of about 30%. As a result, the projections on the sprayed surface were slightly shaved and formed into a planar shape. The mica did not appear on the protruded portions that were shaved and formed into a planar shape, and the mica appeared only on the recessed portions. Next, a top coat was applied to the whole using an acrylic-silicone paint. By applying the top coat in this manner, the durability of the sprayed material can be improved.
By adopting the above spray coating method,
An aggregate of building wall coverings having a very beautiful appearance that is not different from naturally occurring granite was obtained. Finally, the aggregate of the building wall coverings was cut into a predetermined size and separated into individual building wall coverings 10 (see FIGS. 1 and 2).

In the present embodiment, first to third spraying materials 7, 8, and 9 using ceramic aggregates of three colors (white, gray, and black) are used as the spraying materials. However, the color of the spraying material is not necessarily limited to three colors, but may be a plurality of colors such as two colors, four colors, or the like. In this case, the specifications of the spray gun can be changed to a two-head type, a four-head type, etc. accordingly.

Further, in the present embodiment, the spray-coated body 13 is formed by crushing aggregates of different colors into irregular shapes.
And it is formed by applying in a non-mixed multicolored form, but it is not necessarily limited to this configuration.
As a material of the spray-coated body 13, for example, an acrylic resin-based lysine paint or the like can be used.

Further, in the present embodiment, the mica scales are studded in at least the concave portion of the uneven portion of the spray coating body 13, but it is not always necessary to stud the mica scales.

In the present embodiment, mica is sprayed in a state of being mixed with a synthetic resin (acryl emulsion). However, the method is not necessarily limited to this method. , 8, and 9 may be directly sprayed with mica before curing.

Next, a method of constructing an outer wall surface of a building using the building wall covering 10 manufactured as described above will be described with reference to FIGS. First, as shown in FIG. 4, a net 15 was attached to the outer wall surface of the building so as to cover the tiles 23 using an adhesive. This makes it possible to completely prevent the tiles 23 from falling from the outer wall surface of the building.

Next, as shown in FIGS. 5A and 5B, a hole 25 reaching the frame 24 is formed at the center of the tile 23 on the outer wall surface of the building corresponding to almost four corners of the wall covering 10 for the building. The hole was drilled.

Next, as shown in FIG. 4, FIG. 5 (c), and FIG. 6, a stainless steel disc-shaped holding plate 26 is arranged in a state of covering each of the tiles 23 having the holes 25 formed therein. A hollow anchor pin 27 was inserted into an insertion hole 26 a formed in the center of the plate 26. As shown in FIG.
A large number of holes 26b are drilled in 6, and the periphery is curved toward the back side. A straight cut 27a is provided at the distal end of the anchor pin 27, and the insertion hole 2 of the holding plate 26 is provided at the base end.
A flange 27b is provided which is locked at the periphery of 6a. Next, epoxy resin was injected from the base end of the anchor pin 27. As a result, the epoxy resin flows out of the notch 27a at the tip of the anchor pin 27 into the skeleton 24, the epoxy resin hardens, the anchor pin 27 is fixed to the skeleton 24, and the holding plate 26 is attached to the outer wall surface of the building. Fixed to

Next, as shown in FIGS. 4 and 5D,
On the four holding plates 26, a water-resistant epoxy 28 as an adhesive was applied. In this case, as an adhesive in this case,
An inorganic adhesive may be used. In particular, if water-resistant epoxy is used, even if rainwater or the like enters between the outer wall surface of the building and the building wall covering 10, the adhesive strength is not weakened.

Next, as shown in FIG. 4, FIG. 5 (e), and FIG. 7, the building wall covering 10 was stuck on the four holding plates 26. In this case, a gap of about 5 mm is provided between the building wall covering 10 and the outer wall surface of the building for flat adjustment. The lower end of the building wall covering 10 is supported by a fall prevention piece (angle) 29 having an L-shaped cross section. Here, a plurality of holes 12a are formed in the base 12 of the building wall covering 10, and the holding plate 2
6 are also provided with a large number of holes 26b, so that the water-resistant epoxy 28 is applied to the base 12 and the holes 12a, 2b of the holding plate 26.
6b, the bonding strength is increased by the anchor effect, and the building wall covering 10 is securely bonded onto the four holding plates 26. In addition, not only on the holding plate 26,
If the adhesive is also applied to the outer wall surface of the building where the holding plate 26 does not exist, the building wall covering 10 can be more reliably adhered to the outer wall surface of the building.

The above work is repeated, and a large number of building wall coverings 10 are attached to the outer wall surface of the building in a state of being joined vertically and horizontally, so that the repair of the wall surface on which the time-lapsed tile is applied is completed. In this way, by using panelized building wall coverings, it is possible to repair tiled wall surfaces over time in a short period of time and without causing variations in the quality of patterning etc. of the finished surface Can be.
