  2. Description of the Related Art As a building board material 1 that forms an outer wall of a house such as an exterior material, a material formed by applying a cosmetic coating on the surface of a cement-based inorganic board is used. And this exterior board | plate material 1 can be formed in the wall surface of a house side by side, and it can form an outer wall.

  At this time, as shown in FIG. 3 (a), a female fruit 10 and a male fruit 11 are formed at the upper and lower ends of the building board 1, respectively. Although it connects by the fitting of the real 11, the board | plate material 1 for construction adjacent to the right and left is often connected by abutting. And as shown in FIG.3 (b), the sealing material 2 is filled in the joint between the butt | matching edge parts of this building board material 1, and the waterproofing process in the connection part of the building board material 1 is performed.

  When the sealing material 2 is filled in the joints between the end portions of the building board 1 as described above, since the surface of the building board 1 is coated, the color of the sealing material 2 is the same as the surface coating color. If they are different, the sealing material 2 between the building plate materials 1 is conspicuous, and the appearance of the outer wall of the house is impaired.

  Therefore, in Patent Document 1, after the sealing material 2 is filled in the joints between the building plate materials 1, the surface of the sealing material 2 is coated with a paint having a color that matches the color of the building plate material 1. Is inconspicuous.

  However, when the paint is applied to the surface of the sealing material 2 as described above, a painting work is required in addition to the filling work of the sealing material 2, and the paint protrudes when the sealing material 2 is applied. In order not to contaminate the surface, it is necessary to put a tape on the edge of the building board 1 so that it takes a lot of work.

  On the other hand, a coloring agent is mixed in the sealing material 2 and colored according to the color of the surface coating of the building board material 1 and such a colored sealing material 2 is used (for example, patents). Reference 2). In this case, it is not necessary to perform painting after the construction for filling the sealing material 2, and if the color of the sealing material 2 matches the surface coating of the building board 1, the sealing material 2. There is nothing that stands out.

  When the sealing material 2 is colored and used as described above, when the surface of the building board 1 is painted in one color, if the sealing material 2 is colored in the same color as that color, the building board 1 is painted. The sealing material 2 can be colored in a harmonious color, and it is easy to make the sealing material 2 inconspicuous.

  However, when the surface of the building board 1 is painted with a plurality of colors, for example, when a plurality of colors are painted in a pattern arranged in a random manner, the coating of the building board 1 is in harmony. It is difficult to choose a color that doesn't stand out. In particular, when inkjet coating is applied to the surface of the building board 1, it is painted with a set of cyan, magenta, yellow, and black dots, so select an inconspicuous color in harmony with the building board 1 coating. It becomes more difficult to do, and the color matching of the coloring of the sealing material 2 is very difficult.

  Therefore, conventionally, when the building board material 1 is prototyped, the sealing material manufacturer produces a sample sealing material 2 colored in a color close to the paint color of the building board material 1, and this sample is placed on the joint between the building board materials 1. A test for filling the sealing material 2 is conducted, and the surface coating of the building board 1 and the color of the sealing material 2 are actually compared to determine whether or not the color of the sealing material 2 is conspicuous.

  And when the coloring of the sealing material 2 is not sufficiently harmonized with the surface coating of the building board 1 and it is judged visually that the color of the sealing material 2 is conspicuous, the colored sealing material 2 is produced. Then, a test for filling the joints between the building board materials 1 using this sealing material 2 was performed in the same manner as described above, and again the surface coating of the building board material 1 and the color of the sealing material 2 were actually compared, and the sealing material It is determined whether or not the second color is noticeable. Usually, by repeating this test several times, the sealing material 2 colored in an inconspicuous color in harmony with the coating of the building board material 1 is produced.

  Thus, the color matching of the coloring of the sealing material 2 with respect to the coating color of the building board 1 is performed by filling the joints of the building board 1 with the sealing material 2 and coloring the surface of the building board 1 and the sealing material 2. It was necessary to carry out a test for actually comparing the above, and to repeat this test many times through trial and error, and it took a lot of time and effort to color match the sealing material 2.

  The present invention has been made in view of the above points, and it is not necessary to repeat the test of actually filling and comparing the sealing material on the joints of the building board material, and it is time-consuming to color-match the coloring of the sealing material. It is an object of the present invention to provide an architectural plate material for color matching of a colored sealing material and a color matching method of a colored sealing material that can be easily performed without necessity.

  The building board 1 is formed using, for example, a ceramic-based inorganic board such as cement as a base material, and is formed in a horizontally-long rectangular shape, as shown in FIG. 3A, along the longitudinal direction. A female fruit 10 is provided on the upper end surface, and a male fruit 11 is provided on the lower end surface. Both ends in the longitudinal direction of the building board 1 are cut end faces. And the surface of the board | plate material 1 for construction is given the coating for makeup over the whole surface. Of course, it goes without saying that the material and shape of the building plate 1 are not limited to this.

  An outer wall can be formed by mounting a plurality of the building plate 1 on the wall surface of the house. And as shown in FIG.3 (b), the board | plate material 1 adjacent to the upper and lower sides is connected by the fitting of the female fruit 10 and the male fruit 11, and the building board | plate material 1 adjacent on the right and left is a butt | matching edge part. By filling the sealing material 2 between the joints, the connection is made through the sealing material 2. As the sealing material 2, a paste-like amorphous sealing material (so-called wet joint material), a fixed sealing material (so-called dry joint material) such as a rubber gasket, or the like can be used.

  Here, the surface coating of the building plate 1 can be performed by inkjet coating using the inkjet coating machine 4. As shown schematically in FIG. 4, the inkjet coating machine 4 includes a nozzle head 7 provided with ejection nozzles 5, an ink supply tank 12 that supplies ink to the ejection nozzles 5 of the nozzle head 7, and the ejection nozzles 5 of the nozzle head 7. Is formed from a coating control system 13 that controls the ejection of ink from the ink jet, and a conveyor 14 is disposed below the inkjet coating machine 4. The conveyor 14 is arranged from the front position where the building board 1 is introduced into the inkjet coating machine 4 to the position directly below the inkjet coating machine 4 and the rear position where the building board 1 is led out from the inkjet coating machine 4.

  The nozzle head 7 is provided at the lower end of the inkjet coating machine 4, is formed as a long line head in a direction perpendicular to the feeding direction of the building board 1, and is disposed so as to cross the conveyor 14. It is. A number of spray nozzles 5 are arranged on the lower surface of the nozzle head 7 along the longitudinal direction thereof. In the present embodiment, the nozzle head 7 is formed of four types of nozzle heads 7y, 7c, 7m, and 7k that eject inks of yellow, cyan, magenta, and black, and can be painted by full-color printing. I can do it. Similarly, the ink supply tank 12 includes four types. The ink supply tank 12y that supplies yellow ink is supplied to the nozzle head 7y, and the ink supply tank 12c that supplies cyan ink is supplied to the nozzle head 7c. The ink supply tank 12m for supplying the black ink is connected to the nozzle head 7m, and the ink supply tank 12k for supplying the black ink is connected to the nozzle head 7k.

  When the inkjet coating machine 4 formed as described above performs inkjet coating on the surface of the building board 1, the building board 1 is introduced onto the conveyor 14 with the surface to which the building board 1 is coated facing upward. 1 is sent by the conveyor 14 in the longitudinal direction, and passes under the nozzle heads 7y, 7c, 7m, and 7k of the inkjet coating machine 4 in order. Then, while the building board 1 is sent by the conveyor 14 in this way, ink droplets are ejected from the jet nozzles 5 of the nozzle heads 7y, 7c, 7m, and 7k to be applied to the surface of the building board 1. Thus, the surface of the building board 1 can be painted.

  FIG. 2 shows an example of surface coating applied to the building board 1. On the surface of the building board 1, long and narrow brick-like blocks are arranged on the left and right sides, and this row is stacked in multiple stages up and down so that the blocks are randomly shifted left and right so that the blocks do not line up and down. The surface irregularities are formed, and on the surface of each block, a dark color (light color), a light color (light color), and an intermediate color are applied to each block. Is arranged.

  In constructing the building plate 1 having the surface coated as described above as shown in FIG. 3B, the sealing material 2 filled in the joints between the side edges of the adjacent building plates 1 is as described above. Is colored in harmony with the color of the surface coating of the building board 1. Here, when the surface coating as shown in FIG. 2 is performed on the building board 1, since different colors of dark and light colors overlap in the vertical direction, just looking at the aspect of the surface coating in FIG. 2. It is not possible to determine what color the sealing material 2 should be colored to make it inconspicuous in harmony with the color of the surface coating of the building board 1.

  Therefore, the present invention produces a color matching building board A by coating a plurality of coating lines 3 as a color sample of the sealing material 2 on the surface of the building board 1 coated as described above. The color for coloring the sealing material 2 from the painted wire 3 of the color matching building material A is selected and determined.

  FIG. 1 shows a color matching building board A produced by painting a plurality of coating lines 3 on the surface of the building board 1 subjected to the surface coating of FIG. The painted wire 3 is formed so as to be parallel to the side edge of the building board 1 filled with the sealing material 2 and across the building board 1 over the entire width. In the range from the vicinity of the end portion to the vicinity of the other end portion, they are formed at a predetermined constant interval. Moreover, it is preferable to form each coating line 3 in the shape of a strip having a width substantially equal to the width dimension of the sealing material 2. And the coating line 3a of one end among the plurality of coating lines 3 is painted in the same color as the darkest color among the colors painted on the surface of the building board 1 and the other end. The coating line 3i is painted in the same color as the lightest color (light color) among a plurality of colors painted on the surface of the building board 1. Also, the paint lines 3b to 3h in the meantime, the closer to the paint line 3a, the closer to the dark color (dark color) of the paint line 3a, and the closer to the paint line 3i, the closer to the light color (light color) of the paint line 3i. In addition, the color is changed in order from the dark color (dark color) of the paint line 3a and the light color (bright color) of the paint line 3i, and the color is changed in the hierarchy (gradation).

  Here, when ink-jet coating is performed as described above, each coating color of the plurality of coating lines 3 can be determined based on image data used for surface coating of the building board 1. That is, the darkest color (dark color) and the lightest color (light color) are extracted from the image data used for the surface coating of the building board 1 by image processing software. For example, when “Photoshop” (Adobe System) is used as image processing software, these data can be extracted using a “painting tool”. Next, data in which the color tone is changed stepwise between the darkest color (dark color) and the lightest color (light color) is created. The condition for applying the gradation can be obtained by a color difference formula such as Lab based on the data of the darkest color (dark color) and the lightest color (light color). The image data of each of the plurality of paint lines 3 can be created using these color data. In this way, image data of a plurality of coating lines 3 can be easily created, and the surface coating as shown in FIG. 2 is applied to the surface of the building board 1 by the inkjet coating machine 4 as shown in FIG. At the same time as this surface coating, the coating wire 3 can also be coated, and the color matching building board A as shown in FIG. 1 can be easily produced.

  In the color matching building board A produced as described above, each of the plurality of strip-like painted wires 3 vertically traverses the building board 1 vertically in the same manner as the sealing material 2 filled in the joint. Moreover, it forms so that the different color of the surface coating of the board | plate material 1 for construction may cross | intersect on it arrange | positioned up and down. Accordingly, each painted line 3 has an appearance similar to that filled with the sealing material 2 along the side edge of the building board 1, and each building wire 3 is used as a virtual sealing material, and the building board 1 By comparing the surface coating and each coating line 3, it is possible to determine the degree of harmony of the coloring of the sealing material 2 with respect to the surface coating of the building board 1 by actual visual observation.

  Then, the surface coating of the building board 1 and each coating line 3 are visually compared to select the coating line 3 that is most inconspicuous in the entire surface coating composed of a plurality of colors. For example, in the color matching building board A shown in FIG. 1, the painted line 3 e can be selected as the least noticeable painted line 3. By selecting the least noticeable coating line 3 in this way, the color of the coating line 3 can be selected as a color for coloring the sealing material 2.

  When the sealing material 2 is colored with the color of the coating line 3 thus selected, the sealing material 2 can be formed in an inconspicuous color in harmony with the color of the building board material 1 as with the selected coating line 3. Is. Therefore, it is not necessary to repeat the test of actually filling and comparing the sealing material 2 on the joints of the building board 1, and it takes time and effort to color the sealing material 2 that matches the surface coating of the building board 1. It can be done easily without any problems.

  The color matching building plate A of the present invention can be used for color matching of the sealing material 2 as described above, and also for color matching of repair paints. That is, when the surface of the building board 1 is partially damaged, it is repaired by applying a paint to the damaged portion, and when a screw or the like is driven into the building board 1 from the surface, The coating is applied and repaired from above. At this time, it is necessary to match the color of the repair coating with the color of the portion to be repaired. Then, among the plurality of painted lines 3 provided on the color matching building material A, the least noticeable one of the painted lines 3 crossing the color portion of the location to be repaired is selected, and this selected painted line 3 is selected. By using a repair paint that matches the color of the repair, the repair spot can be made inconspicuous.
