  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. 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 no one that aimed to enhance the three-dimensional feeling like never before. Further, in Patent Document 4, the position of the oblique plane formed on the section screen is only a monotonous pattern in which the oblique plane is alternately repeated in the longitudinal direction, such as up, down, up, down,. It was.

  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 addition, a plurality of blocks having a vertical top surface projecting to the outdoor side are formed on the entire decorative surface of the metal surface material, and the upper end and / or the lower end of the top surface of the block are upward. An inclined upper inclined plane, a downward inclined lower inclined plane are formed, and a left inclined plane inclined leftward and a right inclined plane inclined rightward are formed at the left end and / or right end of the top surface of the block. The present invention provides an exterior structure in which an exterior material is constructed on a housing by male-female connection of the exterior material and fixing by a fixture.

According to the exterior structure according to the present invention, since the exterior material having an inclined plane that is thinner than the block and has a gentle slope is formed on either the upper or lower side of the block formed on the decorative surface of the exterior material. Since the plane is formed, a difference is generated in the vertical positional relationship between the blocks, and the design creates an illusion that the positional relationship between the blocks is uneven. Since the inclined plane with a gentle slope was formed on either the left or right side of the block, (2) a difference in the positional relationship between the blocks was created on the left and right sides, as if the positional relationship between the blocks was further promoted. The design creates an illusion. There are features and effects.
