That is, as shown in FIGS. 1, 2 (a) and 2 (b), the exterior material A is an exterior material A in which a core material 3 made of, for example, a synthetic resin foam is sandwiched between a metal surface material 1 and a back surface material 2. It is. Moreover, FIG. 3 is sectional drawing which shows a construction state.

  As an example of the overall shape of the exterior material A, as shown in FIGS. 1, 2 (a) and 2 (b), a core material 3 is provided between a metal surface material 1 and a back material 2 made of a long and thin metal plate. Are formed from a male connecting portion 4 formed at one end in the width direction and a female connecting portion 5 formed at the other end, and a side wall 7 is formed at the lower end of the decorative surface 6 and a side wall 8 is formed at the upper end. Is.

  More specifically, the male connecting portion 4 includes a side wall 7 having the lower end of the decorative surface 6 bent to the back side, an upper surface 9 projecting the tip of the side wall 7 upward, and an engagement piece 10 bending the tip of the upper surface 9 downward. And an engaging groove 11 composed of an upper surface 9 and an engaging piece 10.

  The female connecting portion 5 includes a side wall 8 in which the upper end of the decorative surface 6 is bent toward the back surface, a joint bottom surface 12 in which the tip of the side wall 8 is bent upward, and a bottom surface 13 in which the tip of the joint bottom surface 12 is folded and protrudes downward. It is formed of a fitting piece 14 composed of a joint bottom surface 12 and a lower surface 13, a fixed surface 15 that protrudes by bending the tip of the lower surface 13 upward, and a fitting groove 16 formed by the lower surface 13 and the fixed surface 15. Is. Reference numeral 17 denotes a packing formed for enhancing waterproofness.

  As shown in FIGS. 1 and 4, a plurality of vertical joints T and horizontal joints Y are formed on the decorative surface 6, and blocks B having different sizes in a plurality of rows and a plurality of rows are formed.

As shown in FIGS. 1 and 4, the block B has a vertical plane top surface 6a, an upper inclined plane 6b that is inclined above the top surface 6a toward the indoor side, and an indoor side below the top surface 6a. An inclined plane K composed of the inclined lower inclined plane 6c is formed. In the drawing, the top surface 6a is represented by oblique oblique lines, the upper inclined plane 6b is not filled, and the lower inclined plane 6c is represented by filling. In FIG. 4, 6T is the short side of the block B in the width direction, and 6Y is the long side of the block B in the longitudinal direction.

  The formation method is as follows: (1) When an embossed pattern is formed on the hatched portion of the top surface 6a of the block B, light is reflected in a diffusely reflected state in all directions on the top surface 6a portion where the emboss is formed. In addition, the upper inclined plane 6b and the lower inclined plane 6c formed in the other portions reflect the light in the vertical direction, creating an unprecedented shadow, and the top surface 6a is raised to form a three-dimensional wall. . As for the embossed pattern, the slanted lines in the figure are for showing the embossed part. The lysine pattern, melon pattern, stucco pattern, nishiki pattern, new melon pattern, cast pattern, stripe pattern (vertical, horizontal) , Diagonally), dimple patterns, and the like.

(2) When the upper inclined plane 6b is formed on the upper part of the block B, the surface of the upper inclined plane 6b becomes a mirror surface state due to the upward reflection of light, and the horizontal joint Y on the upper part of the block B The groove is emphasized, and the top surface 6a is raised to form a wall body in which the three-dimensional effect is amplified. See FIGS. 5A and 5B.

(3) When the lower inclined plane 6c is formed in the lower part of the block B, the surface of the upper inclined plane 6b becomes a shadow due to the downward reflection of light, and the upper top surface 6a is raised. Thus, the three-dimensional effect is enhanced, and the shadow is canceled out in the groove portion of the horizontal joint Y below the block B, resulting in a wall body in which the three-dimensional effect is attenuated. Refer to FIG.

(4) When the upper inclined plane 6b is formed at the upper corner of the block B, the surface of the upper inclined plane 6b becomes a mirror surface due to the upward reflection of light at the portion, and the horizontal joint Y on the upper portion of the block B The top surface 6a is raised and the three-dimensional effect is amplified, and the top surface 6a of the block B is formed in a key shape to form a complicated and three-dimensional wall body. See FIGS. 5D, 5E, 6A, 6E, and 7A to 7E.

(5) When the lower inclined plane 6c is formed at the lower corner of the block B, the surface of the upper inclined plane 6b becomes a shadow due to the downward reflection of light, and the upper top surface 6a is The three-dimensional effect is enhanced by bulging, and in the groove portion of the horizontal joint Y below the block B, the shadow is canceled out to form a wall body in which the three-dimensional effect is attenuated, and the top surface 6a of the block B is a key type. The wall is complex and has a three-dimensional effect. See FIGS. 6B to 6E and FIGS. 7A to 7E.

(6) When the upper inclined plane 6b and the lower inclined plane 6c are formed on the diagonal line of the corner portion of the block B, it is possible to prevent unevenness in the processing amount of the embossing of the block B at that portion. See FIG. 6 (e) and FIG. 7 (a).

(7) When the upper inclined planes 6b of the adjacent blocks B or the lower inclined planes 6c are continuously formed, the surface of the upper inclined plane 6b becomes a mirror surface in the portion due to the reflection of light upward. The groove of the horizontal joint Y at the top of the block B is emphasized, and the three-dimensional effect is enhanced, and the upper inclined plane 6b is divided by the vertical joint T, so that the upper inclined plane 6b is in the middle. A divided complex pattern can be formed, and the wall body does not have the monotonousness (repetition of a constant pitch pattern) of embossing with a constant pitch. See FIGS. 8A and 8B.

(8) When the upper inclined plane 6b and the lower inclined plane 6c of the adjacent block B are formed vertically, the block B in which the reflection of light is opposite is formed, and the partition screen boundary of the block B is clarified It becomes. Refer to FIG.

(9) When the lower inclined plane 6c and the upper inclined surface 6b of the upper and lower blocks B are formed to face each other, the horizontal joint Y is further clarified, and thereby the top surface 6a appears to be further raised, which has never been seen before. It becomes a wall that brings out a three-dimensional effect. Refer to FIG.

(10) When the base coil is glossy to promote the shading caused by light reflection, the brightness of the base color (dark) < It can be expressed by a combination of top colors (bright), has a contrast, and has a wall that promotes the three-dimensionality and multicoloredness of the top surface 6a.

(11) A dummy block row R1 is formed by forming a lower inclined plane 6c only at the lower portion of the block B as shown in FIGS. 1 to 4 and FIGS. When the exterior material A is constructed as shown in FIG. 3, the gap between the upper exterior material A and the lower exterior material A is not visible from the outside, and a wall made of a plurality of exterior materials A is formed. You can form a natural single-walled body that is not your body.

(12) A dummy block row R1 is formed by forming a lower inclined plane 6c only in the lower part of the block B as shown in FIGS. Since the pattern of the dummy block row R1 is formed at regular intervals when the exterior material A is applied, the dummy pattern of the dummy block row R1 in which the lower inclined plane 6c is formed only in the lower part of the block B is similarly provided. By forming as shown in FIG. 4, a more natural wall body can be formed. In addition, as the shape of the connection joint γ and the horizontal joint Y, grooves having a narrow interval such as a V-shaped joint and a thread joint as shown in the figure are formed.

(13) Furthermore, in order to solve the sense of incongruity that the pattern in which the lower inclined plane 6c is formed only at the lower part of the block B in the dummy block row R1 is present at a constant interval, the upper part is only above the upper part of the block B which is the opposite pattern. When the dummy pattern of the dummy block row R2 having the inclined plane 6b is formed as shown in FIG. 4, a more natural wall body can be formed.

Of course, it can also be formed by combining the blocks B of (1) to (13). In addition, although the height of each block is formed with the same width | variety in a figure, it can also form with a different width | variety.
