Abstract

PROBLEM TO BE SOLVED: To provide an outer wall material of embossed metal having a decorative surface which improves the appearance of changing light reflection and prevents cracking in the coated or plated surface of a metal plate, by roll embossing for roughness patterning of a metal plate passing through a combined pair of embossing rolls such that both sides of the metal plate are alternately squeezed.SOLUTION: A long outer wall material has a decorative face with many lateral groove joints having a narrow groove shape in approximately parallel with each other along the longitudinal direction of the front face base, and a plurality of vertical groove joints which are joined with the lateral groove joints in an approximately perpendicular direction so as to form many partitioned faces subdivided therewith. One side of the partitioned face is slightly folded toward the surface so as to form a sloped plane and a top face. The partitioned faces having positions of the sloped plane different from each other relative to the top face are alternately arranged adjacent to each other in the longitudinal direction so as to form the decorative face of an outer wall material of embossed metal.

Description

The present invention has a decorative surface that changes the reflection of light by embossing roll processing that adds a concavo-convex pattern by alternately drawing on the front and back of the metal plate through a pair of embossing rolls combined with a metal plate. The present invention relates to an embossed metal outer wall material.

As a wall material of a thin metal plate that produces an effect of changing brightness by changing reflected light, there is a conventional example in which convex region units having substantially parallel concavo-convex patterns in four or more directions are arranged.
(For example, refer to Patent Document 1).

JP 2002-235423 A

In the case of the conventional example in which the convex region unit in which substantially parallel concavo-convex patterns of four directions or more are formed is provided, the effect is emphasized because it is a substantially parallel concavo-convex pattern having a different directionality that produces an effect of changing reflected light. Therefore, it becomes a thin, almost parallel concavo-convex pattern, the impression of the surface texture of the pattern is limited and monotonous, and the flatness of the pattern surface is lost, and the design that shines like a mirror reflecting sunlight Then, the thin substantially parallel concavo-convex pattern breaks the surface of the metal plate by painting or plating in order to add a small rounded process to the metal plate, thereby generating cracks.

This invention forms a metal plate to form an insertion piece at one side end of the front base portion constituting the decorative surface, and forms a fitting groove and a nail piece at the other side end of the front base portion. Concerning the decorative surface of a long external wall material that is continuously connected to construct a wall surface, a plurality of elongated groove-like transverse groove joints are formed along the longitudinal direction of the front base portion, and the transverse groove joints are formed. branches from the middle of the longitudinal groove joint mated lateral groove joints running parallel next to form a plurality, their lateral groove joints and partition surface made of lengths of the following types, separated by a vertical groove joint Form a large number, and form a top surface that forms a large number of small irregularities partitioned by the surrounding horizontal groove joints and vertical groove joints, and the bottom of the horizontal groove joints recessed from the top surface is bent slightly to the surface side to have flatness an oblique plane is formed, the top surface of the swash plane further slightly bent on the back side Continue to the other side with respect to the swash plane of the top surface is bent on the back side of dogleg, contiguous to the lateral groove joints, also both ends in the longitudinal direction of the top surface is bent on the back side to the dogleg A series of slanted planes that are connected to the vertical groove joints recessed from the top surface , and that have a number of oblique planes with different positions relative to the top surface in the longitudinal direction, and a top surface with substantially constant brightness by reflection of sunlight, It is an embossed metal outer wall material that forms an intricate decorative surface that is an oblique plane with different brightness and has a different length .

A. It becomes possible to prevent the occurrence of pocket waves, which are harmful dents on the decorative surface, due to the uneven extension of the metal plate,
B. It becomes possible to prevent warping, twisting, bending, etc. of the metal plate due to the uneven extension of the metal plate,
C. Therefore, the defect rate is reduced, productivity is improved, and cost is reduced.

C. If you want to have multiple ward screen widths,
a. The decorative surface expresses a wide range of diagonal planes with different brightness, and it becomes a decorative surface with a more varied design.
A. Designability is improved.

D. When many small irregularities are formed on the top surface,
a. Incident light is reflected in various directions, almost diffusely reflected, and regardless of the positional relationship between the observer and the outer wall material, a top surface with almost constant brightness is observed from the observer's perspective.
A. Gives the tone to be the key to the decorative design, gives a calm impression suitable for the wall, and improves the design.

E. When the multiple of the total distance between the centers of the vertical groove joints corresponds to the outer periphery of the embossing roll,
a. As the multiple increases, the influence of the oblique plane of embossing is dispersed,
A. It becomes possible to prevent the occurrence of pocket waves, which are harmful dents on the decorative surface, due to the uneven extension of the metal plate,
B. It becomes possible to prevent warping, twisting, bending, etc. of the metal plate due to the uneven extension of the metal plate,
C. Therefore, the defect rate is reduced, productivity is improved, and cost is reduced.

F. When forming a deep transverse groove joint that continues from the top to the bottom,
a. A decorative surface of the outer wall material that is arranged with a dark shadow interrupted on the way below the top surface due to sunlight, etc.
A. Accent the decorative design and give an impression to the wall, improving the design.

G. The pattern with different brightness according to the present invention changes the color of the outer wall material.
a. When it is bright, it feels like a whitish color with reduced saturation, and when it's dark, it feels like a bright color with high saturation,
b. In addition, since the flat surface is an oblique plane, the area where the color is sensed becomes wider, and the difference in color becomes larger.
A. Giving a big change to the wall,
B. Designability is improved.
