Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a decorative ALC panel in which one surface of a lightweight cellular concrete (hereinafter referred to as ALC) panel which has been cured at a high temperature and a high pressure is subjected to decorative finishing by a water pressure.

[0002]

2. Description of the Related Art Generally, an ALC panel is prepared by setting a reinforcing bar mat comprising a plurality of reinforcing mats on a mold, and then performing ALC.
The slurry is injected and foamed, and after a lapse of a desired time, the semi-plastic body is taken out of the mold, cut into a desired thickness with a piano wire, and then charged into an autoclave and steam-cured under high temperature and pressure. And the obtained AL
C panel width is 600mm or less and length is 600-60
The main thing is 00 mm.

[0003] ALC panels are often used for outer walls and the like because of their features such as light weight, fire resistance, heat insulating properties, and easy workability. I hate to have a monotonous appearance in design. Therefore, a decorative ALC panel having a design on one surface has been developed in order to make the monotonous joints inconspicuous. As an example, there is a groove-shaped concave portion having a U-shaped cross section having a flat bottom surface and a flat side surface cut by a cutting tool, but the U-shaped groove-shaped concave portion is linear, In addition, since the appearance is conspicuous, the appearance is similar to that obtained by attaching a small ALC panel, and the monotonous appearance is not improved. In addition, after providing a groove-shaped concave portion having a substantially U-shaped cross section having a flat bottom surface cut by a blade on one surface of the ALC panel, there is also one in which the entire surface of the ALC panel is blasted. In addition, the uncut surface of the ALC panel is also blasted, so
The unevenness on one surface of the ALC panels became ambiguous, and joints between the ALC panels were conspicuous and the wall surfaces had to be monotonous.

[0004] Further, a groove-shaped recess having a substantially U-shaped cross section having a flat bottom surface and a flat side surface cut with a blade is provided on one surface of the ALC panel, and a flaky coating is formed on the bottom surface of the groove-shaped recess. In some cases, the mold material is disposed and the entire ALC panel is blasted to make only the bottom surface of the groove-shaped recess having a substantially U-shaped cross section flat.
In the method of manufacturing an LC panel, it is necessary to use a hard and corrosion-resistant iron mold material or the like in order to avoid erosion of the coated mold material by the shot material to be sprayed, and the heavy load causes a heavy load during handling. There is.

[0005] Furthermore, an ALC panel has been proposed in which the entire surface of the panel is subjected to blasting, and the processed surface is cut with a groove using a rotary blade or the like (see JP-A-63-82702). When the shot material and the cut ALC powder are mixed at the time of blast processing, residual material is generated, or the blast material enters air bubbles in the ALC panel and needs to be cleaned. There was a problem that it took time and effort.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and improves a monotonous wall surface of a conventional decorative ALC panel, and furthermore, a cosmetic ALC panel which is easy to handle during manufacturing. Is provided.

[0007]

The present invention relates to a cosmetic ALC.
The panel manufacturing method is characterized in that an uneven pattern is formed on one surface of the lightweight cellular concrete panel by water jet processing, and then a groove is formed on the surface of the panel on which the uneven pattern has been formed by cutting. It is. At the time when the water jet processing is performed, since it contains moisture, it is once dried, and then the processing of the design joint, that is, the cutting processing for forming the groove is performed. According to this method, an uneven pattern is formed on the surface other than the groove.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing a processing state of a surface of an ALC panel by a water jet according to an embodiment of the present invention. FIG. 2 is a side view showing the ALC panel at the time of performing a water jet processing. FIG. 3 is a side view showing an ALC panel provided with joints by cutting, and FIG. 4 is a perspective view showing a part of the completed ALC panel after processing, wherein 1 is an ALC panel, and 2 is a concave groove (joint). Reference numeral 3 denotes a water jet nozzle, 4 denotes a water jet, 5 denotes an unevenness formed by the water jet, and 6 denotes a transport roller.

While the ALC panel 1 is conveyed by the conveying rollers 6, the water jets 4 jetted from a plurality of water jet nozzles 3 arranged in the panel width direction above the ALC panel 1 form irregularities 5 on the entire panel surface. You. Since the ALC panel 1 is vulnerable to a local impact, it is locally eroded by the water pressure of the water jet. Therefore, the depth of the surface unevenness 5 is changed as shown in FIG. Becomes possible. At the time when the water jet processing is performed, the water is absorbed by the ALC panel 1, and before the joint processing is performed, the surface of the ALC panel 1 is forcibly or naturally dried to remove the water absorbed by the panel. Remove. Thereafter, the ALC panel 1 having the unevenness 5 formed on the entire panel surface by the water jet 4
A concave groove 2 having a constant depth and a constant width is formed on the surface of the tile by, for example, a joint of a tile.

As shown in FIG. 4, the surface of the ALC panel 1 thus obtained has a stone surface composed of unevenness 6 having a natural texture formed by water jet processing and a concave groove having an artificial texture. 2 is formed. It goes without saying that the pattern formed by the grooves 2 is not limited to the grid pattern shown in FIG. 4, but may be a pattern that is in the shape of a circle, a polygon, or a flower or a tree.

[0011]

As described above, according to the method of the present invention, although it is an ALC panel, it gives an appearance as if a heavy tile is attached, and the surface pattern has an artificial texture like a tile joint. Because it is composed of a concave surface with a concave surface and a stone surface having a natural texture, it is possible to produce an excellent ALC panel without a monotonous design, and when producing an ALC panel with high designability. The use of a water jet has the advantage that handling is easy, and since no shot material or the like is used, no trouble is required for the processing of residual material after cutting.
Further, not only general ALC panels but also decorative panels are stored and moved in a stack of several sheets. However, even in this case, since a flat plane portion composed of an unprocessed surface remains, the stacked ALC panels are There is also a remarkable effect that there is almost no problem that the surface is chipped or chipped due to displacement.
