Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a perspective view showing an outer wall accessory 5 according to Embodiment 1 of the present invention. In the drawing, for example, a plurality of siding materials 2 (outer wall materials) having a rectangular outer shape when viewed from the outside of a building are attached to a building housing 1 of a building such as a house. Each siding material 2 is arranged such that its longitudinal direction is along the height direction of the building. Although not shown in the drawing, joint portions including concave portions and convex portions are provided at both ends in the longitudinal direction of each siding material 2. Each siding material 2 is connected along the height direction of a building by joining those joint parts. At the projecting corner of the building, the siding material 2 constituting different wall surfaces meet to form a gap (protruding corner) extending in the longitudinal direction along the height direction of the building.

  A base material 3 is fixed to the building housing 1 at a position corresponding to the gap. A plurality of outer wall accessories 5 for covering the gap are attached to the base material 3. The outer wall accessory 5 constitutes a corner of the building when viewed from the outside of the building. Hereinafter, the surface of the outer wall accessory 5 that appears in the exterior of the building is referred to as a decorative surface 5a. Concavities and convexities (embossed patterns) are formed on the outer surface of the siding material 2 and the decorative surface 5 a of the outer wall accessory 5. In addition, the outer surface of the siding material 2 and the decorative surface 5a of the outer wall accessory 5 are painted in consideration of design and corrosion resistance.

  Next, FIG. 2 is a perspective view showing the outer wall accessory 5 of FIG. 1 when viewed from the back side. In the figure, an example of the outer wall accessory 5 having the cover member 50 and the core member 51 is shown. As described above, when the outer wall accessory 5 is attached to the base material 3, the front side of the cover member 50 appears on the exterior of the building. That is, although it does not appear in FIG. 2, the decorative surface 5 a (see FIG. 1) is provided on the front side of the cover material 50.

  The cover member 50 is bent into a L-shaped cross section as a whole so as to constitute a corner of the building (bending at 90 °). In addition, both ends in the width direction of the cover material 50 are folded back (180 ° bending) so as to prevent the end of the plate material that is the material of the cover material 50 from appearing in the appearance of the building. Further, the sandwiching pieces 50a provided at the upper and lower ends of the cover member 50 are folded back (180 ° bending) so as to sandwich the core member 51. That is, the outer wall accessory 5 is configured by bending the material of the cover member 50 cut into a predetermined shape.

  The core member 51 is fixed to the back side of the cover member 50 by folding the holding piece 50a. The core member 51 is provided with an engaging portion 51 a having a triangular cross section. The outer wall accessory 5 is attached to the base material 3 by engaging the engaging portion 51 a with the base material 3. In FIG. 2, the cover member 50 and the core member 51 included in the outer wall accessory 5 are shown as separate bodies, but the cover member 50 and the core member 51 may be integrated. You may comprise what has the function of both the cover material 50 and the core material 51 which are shown in FIG.

  Next, FIG. 3 is a flowchart showing a method of manufacturing the outer wall accessory 5 of FIGS. 1 and 2. When the outer wall accessory 5 shown in FIGS. 1 and 2 is manufactured, first, a flat plate material that is a material of the cover material 50 (outer wall accessory 5) and includes a region to be the decorative surface 5a is prepared (step S1). ). In the present embodiment, the flat plate material is a larger plate material before the cover material 50 before bending is cut out. However, the flat plate material may be the cover material 50 before bending that is cut into a predetermined shape. As the flat plate material, any one of a coated hot-dip Zn-plated steel plate, a painted stainless steel plate, a painted Al plate, a coated Zn-plated stainless steel plate, a painted hot-Al plated steel plate, and a painted Al-plated stainless steel plate is used.

  Next, the outer wall accessory 5 is molded (step S2). In the molding process, the flat plate material is subjected to an overhanging process such as embossing. In the overhang processing, irregularities with a depth of 16 mm or less are formed on the surface of the flat plate material. The reason why the depth of the unevenness is 16 mm or less is to enable the subsequent coating by inkjet printing to be performed more reliably. Note that the depth of the unevenness is the height from the top surface of the convex portion formed by the overhanging process to the bottom surface of the concave portion. Next, a plate material having a predetermined shape (cover material 50 before bending) is cut out from the flat plate material, and the plate material is bent to form the outer wall accessory 5 shown in FIGS. 1 and 2. .

  Next, the decorative surface 5a is painted by ink jet printing (step S3). Ink jet printing is printing in which a fine granular paint (ink) is sprayed from the print head onto the surface of a flat plate material. After the outer wall accessory 5 is fixed to a predetermined base, the decorative surface 5a is painted with the print head facing the decorative surface 5a. A coating material having an arbitrary number of colors according to a required design can be sprayed on the surface of the flat plate material in a single coating process.

  In inkjet printing, a three-dimensional appearance (shadow) can be expressed on the decorative surface 5a by arranging light and dark colors in the vicinity. Moreover, in inkjet printing, a coating material can be apply | coated according to the distribution of the convex part and recessed part which were formed by the overhang | projection process. Specifically, the first color (light color) can be applied to the convex region, and the second color (dark color) darker than the first color can be applied to the concave region. Thereby, an impression as if the unevenness is deeper than the actual depth can be given to the viewer.

  In this ink jet printing, a water-based ink containing water as a main solvent can be applied to the decorative surface 5a. However, it is preferable to apply UV ink that is cured by ultraviolet irradiation to the decorative surface 5a. In the case of applying UV ink, after the UV ink is attached to the decorative surface 5a, the UV ink is cured by irradiating the surface of the decorative surface 5a with ultraviolet rays. By using the UV ink, it is possible to prevent the ink applied in the vicinity from being mixed, and a clearer design can be realized.

  Next, clear coating is applied to the flat plate material that has been ink-jet printed (step S4). The purpose of clear coating is to protect the printed surface. Arbitrary clear coating composition and film thickness can be selected according to the purpose, such as improvement of scratch resistance, lubricity and corrosion resistance, and improvement of weather resistance of the printed surface by ultraviolet absorption or blocking. As a coating method, a method capable of uniformly coating such as roll coating, spraying, printing, and bar coating can be selected.

  In such a manufacturing method of the outer wall accessory 5 and the outer wall accessory 5, the decorative surface 5 a that appears on the exterior of the building is painted by ink jet printing, so according to the design of the decorative surface 5 a by a single painting process. In addition, coating with an arbitrary number of colors can be easily performed. Thereby, the coating of a plurality of colors can be performed more easily, and the production efficiency can be improved. In particular, since the decorative surface 5a is applied by ink jet printing after the shape of the outer wall accessory 5 is formed, it is possible to avoid the stress caused by the bending process from acting on the ink surface, and the bending may cause a crack in the ink surface. The ink surface can be prevented from peeling off. In addition, when the ink is applied to the outer wall accessory 5 provided with unevenness by transfer as in the conventional method, the ink is applied only to the convex portion and not to the concave portion. By coating by ink jet printing as in the present invention, ink can be easily applied to both the convex and concave portions, and a more three-dimensional pattern can be expressed.

  In addition, in inkjet printing, the first color is applied to the convex region formed by the overhanging process, and the second color darker than the first color is applied to the concave region formed by the overhanging process. It is possible to give the viewer an impression that the image is deeper than the actual one, and the design can be improved.

  In addition, in ink jet printing, the UV ink that is cured by ultraviolet irradiation is applied to the decorative surface 5a, so that different color inks applied in the vicinity can be prevented from being mixed, and a clearer design can be realized.

  In the embodiment, the description has been given so that the flat plate material is subjected to the overhanging process, but the overhanging process may be omitted, and the unevenness may be expressed on the decorative surface only by ink jet printing. However, by providing unevenness on the decorative surface by overhanging, the light reflectance can be lowered and the design can be improved.

  Moreover, in embodiment, although it demonstrated that the outer-wall accessory 5 was comprised so that the clearance gap (protruding corner part) in the corner | angular part which a building protrudes might be configured, the outer-wall accessory was a hollow of a building. It can also comprise so that the space | gap (a corner part and joint part) formed in a corner | angular and the flat wall surface of a building may be plugged up.
