Description

[Detailed Description of the Invention] The present invention relates to an aluminum alloy architectural shape having a beautiful straight-grain decorative pattern formed on the outer surface of the extruded shape.

BACKGROUND ART Conventionally, it has been known to form a vertical striped pattern on an aluminum alloy architectural profile by forming a large number of protrusions or grooves across the width of the outer surface of the extruded profile. (For example, registered design No. 445995,
(Refer to Publication No. 397610) However, in this case, both the top surface shape of the convex stripes and the bottom surface shape of the concave stripes formed on the outer surface of the extruded section are simply flat surfaces or curved surfaces, so the extrusion is uniformly colored or not colored. There is not much difference in color tone between the convex and concave lines on the outer surface of the profile, and when viewed as a whole, it is perceived as an indistinct vertical striped pattern with a uniform tone. In addition, in view of this situation, if the height of the convex or concave stripes is increased in order to emphasize the vertical striped pattern, it will be perceived as something far different from a straight-grained pattern that has a natural woody feel.

As described above, in the extruded shape material with the vertical striped pattern disclosed in the prior art, even if the width, height, pitch, etc. of the protrusions or grooves are changed variously, the outer surface of the extruded shape material remains unchanged. The aesthetic effect could only be achieved by adding a large number of parallel vertical stripes to the surface.

This invention was devised in view of the above circumstances, and its purpose is to provide an aluminum alloy architectural shape having a clear straight-grained pattern with a rich sense of color tone.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a front view of an example of the implementation of the present invention, in which a large number of vertical lines are formed on the outer surface of an extruded section 1 by convex stripes 2 with a height of 15 μm to 0.5 mm that are continuous in the longitudinal direction of the section. It is what it is. The adjacent distances of these vertical stripes may be changed as appropriate, for example, the adjacent distances from the right side to the left side in Figure 1 may be changed so that they become larger in one direction such as a < b < c < d < e. Good.

FIG. 2 shows an enlarged cross-sectional view of - in FIG. 3 is formed. Then, a colored film layer 4 exhibiting a gold color is formed on the entire outer surface of the profile 1,
Further, a coating layer 5 made of a transparent resin paint to which a matte material is added as necessary is formed thereon. The example shown in FIG. 2 is an example in which the depth of the reflective groove 3 is approximately equal to the height of the protrusion 2.

Figure 3 and the following are modified examples, and Figure 3 shows the reflective groove 3 (parts with the same names are indicated by the same symbols. The same applies hereinafter).
This is an example where the height is shallower than the height of the ridge 2, and a horizontal portion 6 is formed at the bottom of the groove.

In FIG. 4, the depth of the reflective groove 3 provided on the protrusion 2 is made deeper by h than the height H of the protrusion 2, and the groove bottom is formed into a curved surface portion 7.

FIG. 5 shows an example in which two reflective grooves 3 are provided on the protrusion 2. The number of reflective grooves 3 is not limited to two, but a plurality of reflective grooves 3 may be provided.

In FIG. 6, grooves 8 are provided, and reflective grooves 3 are provided at the bottom of the grooves 8.

In FIG. 7, a concave line 8 is provided on the convex line 2, and two reflective grooves 3 are provided at the bottom of the concave line 8. The number of reflective grooves 3 is not limited to two, and a plurality of reflective grooves 3 may be provided.

FIG. 8 shows an example in which convex strips 2 with reflective grooves 3 and concave strips 8 are alternately provided.

The height of the protruding or concave stripes is preferably about 15 μm to 0.5 mm.
Further, the distance between adjacent convex lines, concave lines, or concavo-convex lines is preferably 1 mm to 5 mm. Furthermore, the width of each convex or concave line is preferably 0.5 mm to 2 mm.

In the examples shown in FIGS. 3 to 8, a colored film layer 4 and a transparent coating layer 5 are also formed.

In addition, by changing the distance between adjacent vertical stripes, for example, increasing the distance in one direction, or by forming a colored film layer or a transparent coating layer on the surface of the shape, it can have a more natural wood feel. A straight grain pattern is obtained. The colored film layer preferably has a gold color. The above effect is further promoted by adding a matting additive to the coating layer. Furthermore, by changing the combination of convex and concave lines and the number of reflective grooves, a wide variety of straight-grain patterns can be obtained.

If the reflective groove has an acute angle to the bottom, a concentrated load will be applied to that part during extrusion molding, and the die will be easily damaged. Therefore, by making the groove bottom a curved or horizontal surface, damage to the die can be reduced. .

To manufacture the product of the present invention, an aluminum profile having desired ridges, grooves, and reflective grooves on its surface is formed by extrusion, and a colored film layer is formed on the aluminum profile. The method for forming the colored film layer is a dyeing method in which an anodic oxide film is formed by a conventional method and then colored using a dye or pigment.

An electrolytic coloring method in which an anodic oxide film is formed by a conventional method and then electrolyzed in a bath containing gold layer salt using alternating current or direct current.

An electrolytic coloring method in which an oxide film is formed in a bath using an organic acid and colored at the same time.

There are methods such as the following, but a colored film layer having a gold color is formed on the surface of an extruded aluminum shape by the method described below. Subsequently, a conventional transparent paint is applied by dip coating, air spraying, airless spraying, electrostatic coating, powder coating, or the like. In this case, known matting additives such as silica-based and alumina-based additives may be added to the transparent coating.

According to the present invention, instead of just a convex or concave line, the convex or concave line is limited to a height of 15 μm to 0.5 mm, and an acute-angled reflective groove is formed on the convex or concave line, so that light can pass through the reflective groove. When hit, a diffused reflection phenomenon occurs, and as a result of this phenomenon, the reflective grooves are perceived as a dark color while the other parts are perceived as a light color, resulting in a sharp difference in color tone between the two. Therefore, an aluminum alloy construction material having a clear straight-grained pattern can be obtained.

The present invention is as described above, has a straight grain pattern with a rich sense of color tone, and is effective when applied to fittings, etc.
