  Patent Document 1 relates to an “embossed metal plate”, which can maintain the flatness of flat portions at both ends of a metal plate even when the metal plate is passed between embossing rolls to deeply emboss vertical and horizontal groove joints. is there. Patent Document 2 relates to an “embossed decorative plate”, which is seen by the influence of light reflection by engraving a block with a balanced groove pattern based on two diagonal lines intersecting each other at an angle. The effect of different color tone depending on the direction is exhibited. Further, Patent Document 3 relates to “wall material”, and at least four directions of substantially parallel striped patterns are formed on the surface of the convex region, and the color tone and the color of the color are changed depending on the change of the position of the light source and the change of the viewing direction. The ones with varying shades are described. Further, Patent Document 4 relates to an “embossed metal outer wall material” in which section screens having mutually different oblique plane positions are alternately formed with decorative surfaces adjacent in the longitudinal direction.

However, both Patent Documents 1 to 4 have the idea of embossing the decorative surface of a metal plate material to improve the designability, workability, etc., but the monotonous appearance is repeated and the light reflection is unified. There was nothing that intended to enhance the three-dimensional effect by bulging the top surface like never before. Further, in Patent Documents 1 to 4, there is no “L-shaped top surface” of the present invention, and in Patent Document 4, the position of the oblique plane formed on the section screen is up along the longitudinal direction, It was only a monotonous pattern that was repeated alternately on the diagonal plane, such as down, up, down,.

  In order to solve such drawbacks, the present invention provides a long exterior material in which a core material is formed between a metal surface material and a back material, and a male-female connection structure is formed at the upper and lower ends of the metal surface material. In this case, a plurality of blocks having a vertical top surface projecting outward are formed on the entire decorative surface of the metal surface material, and an upper inclined plane is formed at the upper corner of the top surface of the block, and / or Alternatively, an L-shaped top surface is formed by forming a lower inclined plane at the lower corner portion, the top surface is colored, a stipple color is applied to the decorative surface, and the stipple color is lighter than the top surface, The lower inclined plane provides an exterior material in which a shade having a darker color relationship than the top surface is formed.

  According to the exterior material according to the present invention, an L-shaped top surface is formed on the top surface of the block, and the stippling color formed on the decorative surface is lighter on the upper inclined plane than on the top surface, and the lower inclined plane is on the top surface. By forming shades of dark color relationships, (1) a three-dimensional effect can be produced and a single material can be displayed like a multicolored design. (2) By forming an L-shaped top surface in each block, the shape of the block has an L-shaped (key-shaped) shape, and a wall with a feeling of movement is formed in a mediocre pattern. (3) Because the stippling color formed on the decorative surface is lighter than the top surface of the upper inclined plane and darker than the top surface of the lower inclined plane, the shade of light from sunlight and the light due to inclination are formed. Due to the effect of diffuse reflection of light and the synergistic effect of shades of color, it will be an exterior material that has an unprecedented sharpness and a gentle light image. There are features and effects.
