DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall covering for a building having an appearance similar to that of natural stone, particularly marble, and a method of spray coating a building to obtain such a wall covering for a building. . In more detail, even when viewed from a distance closer to the marble and far away, the peculiar “insect eating pattern” of marble
And a method for spray-painting a building to obtain such a building wall covering.

[0002]

2. Description of the Related Art Conventionally, as the finishing of an outer wall of a building,
Natural stone is often used due to its aesthetics and weatherability. For example, there is a method in which marble is used as it is for a wall or a pillar, or a thin plate is attached to an outer wall or the like. here,
“Buildings” includes not only constructed objects, but also blocks,
Also includes building materials used for buildings such as panels and boards.
Unless otherwise specified, the work of applying a pattern or the like to a building surface using a fluid material is referred to as “painting” or “coating”, unless otherwise specified. .

[0003] As a method of applying a pattern or the like to the surface of an outer wall or the like of a building, for example, a lysine-based (composition including aggregate)
And a method of applying a coating material by a trowel coating method, a roller coating method, a spray coating method, or the like. The ironing method is a method in which a material is transferred to a surface of a building and spread by using the iron. The roller coating method is a method in which a material is transferred to the surface of a building using a roller or an iron, and is spread by a roller. Since these are performed by hand, large patterns can be provided, but they are not suitable for thick coating and large-area coating. The spray coating method is a method in which a material is sprayed from a spray gun using the power of compressed air to perform coating. Here, in the coating method using a lysine-based material, since the material is composed of a granular material such as natural stone, ceramic, and baked aggregate, a synthetic resin emulsion, and a paint, it is possible to perform thick coating to a certain extent. .

A conventional method of spray coating a building to obtain a marble-like wall covering for a building will be described below. FIG. 8 is a schematic process drawing showing a spray coating method for a building in the prior art.

Next, as shown in FIG. 8 (e), after the lower blown layer 53 is completely dried, a spray material prepared in the same color as the lower blown layer 53 is not diluted on the lower blown layer 53 without dilution. The upper blow layer 54 is formed by using as it is and spraying it randomly in a large ball shape. In this case, since the upper blown layer 54 is randomly sprayed in a large ball shape, the upper blown layer 54 has portions 55 where the lower blown layer 53 is exposed.

Next, as shown in FIG. 9 (f), immediately after forming the upper blowing layer 54, water is sprayed from above, and the upper blowing layer 54 is moved in one direction using a stainless steel ironing iron. Really Thereby, the upper blow layer 54 is leveled,
The “site 55 where the lower blown layer 53 is exposed” existing in various places of the upper blown layer 54 forms an insect eating pattern 56 peculiar to marble.

[0009] Next, as shown in FIG.
The release paper 57 on the front side of No. 2 is peeled off. Finally, FIG. 9 (h)
After the upper blow layer 54 is completely dried, the joint bars 52 are removed and a top coat is applied twice using an acrylic-silicone paint as shown in FIG. Thus, a marble-like building wall covering having joints 58 is obtained.

Is sprayed with the compressed air generated by the use of the above, and is applied to the outer wall of a building or the like.

The spray gun 1 is configured so that the paint nozzle 11 is opened and closed by retreating or advancing an air nozzle (not shown) (needle valve system). That is,
An air nozzle having a double structure is attached to a piston (not shown). By switching the switching valve 4, the piston moves backward or forward, and the compressed air and the blowing material are injected or cut off. The spraying of the spray material is performed intermittently in an appropriate cycle.

First, as shown in FIG. 3A, a resin mortar is placed on an outer wall 20 of a building or the like by using a metal trowel.
mm. Then, on the resin mortar,
The sealer was sprayed using air spray. As described above, the primer layer 21 was formed on the outer wall 20 and the like of the building. Next, a joint color was applied on the primer layer 21.

Next, as shown in FIG. 3 (b), a joint rod 22 made of foamed resin was stuck on the primer layer 21 to which the joint color was applied. Here, an adhesive 23 is applied to the back surface and the front surface of the joint bar 22, and a tape (release paper) 24 for preventing the adhesive material is further applied to the back surface and the front surface. Therefore, when the joint bar 22 is attached to the primer layer 21, the release paper 24 on the back side of the joint bar 22 is peeled off.

Next, as shown in FIG.
On the primer layer 21 to which No. 2 was adhered, downward spraying was performed using a spraying material prepared in black. That is, the switching valve 4 is actuated by a flow switch (not shown) to flow compressed air through the flow path 12, and the spray gun 1
The inner piston is retracted to the right in FIG. 5, and the air nozzle attached to the piston is retracted in conjunction therewith. Thereby, the paint nozzle 11 is opened. Simultaneously with the opening of the paint nozzle 11, the compressed air flowing through the flow path 12 flows through the flow path 15, and this compressed air is supplied to the operating portion of the shut-off valve 5, and the shut-off valve 5 is opened. Thereby, the compressed air supply path 6
And the compressed air supply passage 14 to the air nozzle, and compressed air is ejected from the paint nozzle 11 through the compressed air supply passage 14 through the air nozzle. At this time, the paint nozzle 11
Is opened, the spray material is supplied to the paint nozzle 11, and the spray material is ejected from the paint nozzle 11 by compressed air supplied from the air nozzle. In this case, the spray gun 1 used was a paint nozzle in which the diameter of the paint nozzle 11 was set at 4 to 9 mm and the blowing pressure was set at about 2 kg / cm ² (Rissing gun). Further, as the spraying material, a material prepared by diluting 23 kg prepared as described above with 1 kg of water further added was used. As a result, the spraying material prepared in black was sprayed evenly in a wide space on the primer layer 21 to which the joint bars 22 were stuck, and the lower blow layer 25 was formed. Here, the spray amount of the spray material is about 1 kg / m ² , and the thickness of the lower blow layer 25 is 1.0 to 1.5 mm.

Next, as shown in FIG.
The spraying material on top of 2 was removed. Next, as shown in FIG. 3 (e), after the lower blown layer 25 is completely dried, a spray material prepared in a lighter (beige) color than the lower blown layer 25 is formed on the lower blown layer 25. The upper blowing was performed using.
In this case, as the spray gun 1, a spray nozzle in which the diameter of the paint nozzle 11 was set to 10 to 18 mm and the blowing pressure was set to about 1 to ² kg / cm ² (stucco gun) was used. Further, as the spraying material, the spraying material prepared as described above was used without dilution. This allows
On the lower blowing layer 25, a spray material mixed in a beige color was randomly sprayed in a large ball shape (equivalent diameter: 3 to 10 mm). Here, the spray amount of the spray material is 3
１２12 kg / m ² . As described above, the upper blowing layer 26 having a thickness of 2 to 8 mm was formed on the lower blowing layer 25. still,
Since the upper blown layer 26 is randomly sprayed in a large ball shape, a portion 27 where the lower blown layer 25 is exposed can be present in some places of the upper blown layer 26, thereby forming a pesticidal pattern peculiar to marble. It becomes possible.

Next, as shown in FIG. 3 (f), immediately after forming the upper blowing layer 26, the upper blowing layer 26 was spray-sprayed using a white-blown spraying material. . In this case, as the spray gun 1, a spray nozzle in which the diameter of the paint nozzle 11 was set to about 8 mm and the blowing pressure was set to 1 to ² kg / cm ² was used. Further, as the spraying material, the spraying material prepared as described above was used without dilution. Thereby, the spraying material 28 prepared in white was sprayed on the upper blowing layer 26 in a dispersed state. Here, the spray amount of the spray material to be sprayed is 200 to 500 g / m ² .

Next, as shown in FIG. 4 (g), immediately after spraying, water is sprayed from above, and the upper surface of the upper blowing layer 26 is moved in one direction using a stainless steel ironing iron. I was sorry. As a result, the upper surface of the upper blowing layer 26 is leveled, and the white blowing material 28 scattered and blown on the upper blowing layer 26 is stretched in a streak shape. A white streak pattern was formed. As a result, building wall coverings closer to natural marble could be realized. In addition, an insect-eating pattern 29 peculiar to marble was formed by “the portion 27 where the lower blown layer 25 was exposed” existing in various places of the upper blown layer 26.

Next, as shown in FIG.
After the release paper 24 on the front side of No. 2 was peeled off and the sprayed material was completely dried, the joint rod 22 was removed as shown in FIG. 4 (i).

Next, as shown in FIG. 4 (j), first, the upper surface of the upper blowing layer 26 is lightly polished using a disc sander, and then the upper surface of the upper blowing layer 26 is polished using an orbital sander. It was almost completely polished to a state close to a mirror surface. Thereby, the planar shape portion 30 of the upper blowing layer 26 is formed.
Edge became sharp. As a result, the boundary between the planar shape portion 30 of the upper blowing layer 26 and the insect-eating pattern (recess) 29 becomes clear, and the insect-eating pattern 29 can be clearly identified even when the painted building is viewed from a distance. Is now available. In addition, it is possible to bring out a feeling of insect eating pattern closer to the real thing. Further, in this case, a black spraying material is used as the lower blowing layer 25, and a lighter (beige) spraying material than the lower blowing layer 25 is used as the upper blowing layer 26. It can be clearly identified.

Finally, after removing the polishing residue, a top coat was applied twice using an acrylic-silicon paint. By applying the top coat in this manner, the durability and weather resistance of the sprayed surface can be improved. Through the above steps, a building wall covering material having joints 31 and having a pecking pattern peculiar to marble was obtained.
The thickness of the obtained building wall covering material was 2.0 to 5.0 mm.

Note that, in the present embodiment, the material prepared as described above is used as the spraying material, but the spraying material is not necessarily limited thereto. The same effect can be obtained.

Further, in the present embodiment, a dark color is used as the color of the spray material of the lower blow layer 25 and the upper blow layer 26 is used.
Is used as the color of the spray material, but is not necessarily limited to this configuration. The light color is used as the color of the spray material of the lower blow layer 25, and the color of the spray material of the upper blow layer 26 is used as the color of the spray material. Dark colors may be used. However, in order to make the insect biting pattern (recess) 29 stand out clearly, it is preferable to use a dark color as the color of the spray material of the lower blow layer 25 and a light color as a color of the spray material of the upper blow layer 26.

Further, in the present embodiment, the color of the spray material of the lower blow layer 25 and the color of the spray material of the upper spray layer 26 are different, but the present invention is not necessarily limited to this configuration. Lower spray layer 25 using color spray material
And the upper blowing layer 26 may be spray-painted. That is,
Even if the upper surface of the upper blowing layer 26 is polished and the edge of the planar shape portion 30 of the upper blowing layer 26 is merely brought into a sharp state, the insect-eating pattern (recess) 29 can be clearly identified from a distance. it can.

[0036]

As described above, according to the present invention,
Since the upper blown layer is sprayed at random so that the lower blown layer is exposed, it is possible to bring a state in which an insect-eating pattern peculiar to marble is formed. In addition, since the upper surface of the upper blown layer is polished into a planar shape, the edge of the planar shape portion (the portion excluding the insect-eating pattern portion) of the upper blown layer becomes sharp. As a result, the boundary between the planar shape portion of the upper blowing layer and the insect-eating pattern portion becomes clear, so that even when the painted building is viewed from a distance, the insect-eating pattern can be clearly identified, and more. You can bring out the feeling of insect eating pattern close to the real thing.
