Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called decorative ALC panel obtained by processing and finishing the surface of a lightweight cellular concrete panel (hereinafter, referred to as an ALC panel) cured by high-temperature and high-pressure steam, and a method of manufacturing the same.

(Conventional technology) ALC panels are lightweight, ready-made panels reinforced with reinforcing materials such as reinforcing steel cages inside.
Known as panels a few meters in length. This ALC
Panels have excellent properties such as light weight, fire resistance, heat insulation, workability, etc., but the wall made of ALC panels has panel joints visible at 60 cm intervals and does not like to have a monotonous appearance. Was.

Therefore, conventionally, a decorative ALC panel in which a groove is cut on the surface of the ALC panel using a rotary blade or the like to form a lattice-like pattern or the like has been used. In this conventional decorative ALC panel, a groove similar to the joint shape between the panels, that is, a groove having a smooth side wall surface and a bottom surface as a whole, which is visible on the surface as bubbles are cut off, is provided in the panel. Although the effect of making joints between panels less noticeable is obtained, the grooves formed on the panel surface are straight linear grooves, and the wall composed of this panel has the appearance of attaching a small ALC panel It was monotonous, leaving the appearance composed of only ALC panels.

Also, as can be seen in JP-A-63-82702, ALC
After applying blasting to the entire surface of the panel, a panel has been proposed in which the processed surface is cut into grooves using a rotary blade or the like. Since it is the same as a conventional decorative ALC panel, it again had the appearance of attaching a small ALC panel whose surface was processed, and had a monotonous wall surface.

Further, as disclosed in JP-A-63-82705, ALC
After cutting grooves on the surface of the panel using a rotary blade or the like, there has been proposed a panel in which the entire surface of the panel is blasted, but since the panel surface is entirely blasted including the groove. The grooves also have irregularities, and if this panel is used to form a wall, the presence of the grooves is less noticeable,
In addition, the joints between the panels became grooves having different appearances, and the walls formed by the panels became clear panels constituted by large panels, and the appearance was also monotonous.

(Problems to be Solved by the Invention) The present invention relates to a conventional ALC panel,
Accordingly, it is an object of the present invention to provide a novel decorative ALC panel that eliminates the drawback that only a monotonous wall surface can be obtained because of being composed of a single ALC panel, and that gives a single ALC panel the appearance of being formed by a plurality of panels.

(Means for Solving the Problems) The present invention provides (1) an ALC panel which is entirely formed of the same ALC and has a groove formed by cutting with a cutting tool on its surface, and only the bottom surface of the groove has a smooth surface. A cosmetic AL, characterized in that the other surface portion is constituted by a rough surface having irregularities by blasting including the side wall surface of the groove.
A groove is formed on the surface of the C panel and (2) the ALC panel by cutting with a blade, a flaky coating is placed only on the bottom of the groove, and the entire panel surface is blasted. And a method of manufacturing a decorative ALC panel characterized by being removed.

That is, in the decorative ALC panel of the present invention, only the bottom surface of the groove is a smooth surface cut by a cutting tool, and the other side surface and the surface of the groove are blasted with a blast material. It is a rough surface having small irregularities. In such a panel, the surface of the ALC panel is cut in a groove at a predetermined position with a blade in the same manner as before, and then a flaky coating is placed only on the bottom of the groove to protect only the bottom of the groove. Then, conventionally known blast material, for example, a number of small steel balls
It can be manufactured by projecting onto the ALC panel, eroding the entire panel surface except for the coating portion with a blast material, and then removing the coating material.

The decorative ALC panel of the present invention thus obtained is, for example, as shown in FIG. 1, a rough surface having small irregularities on the entire surface where the side wall surface and the surface portion of the groove are blasted with a blast material, This portion has the same appearance as the split surface of the stone, and only the bottom surface of the groove is a smooth surface cut with a cutting tool, which is different from the texture of the stone.

Hereinafter, the makeup ALC panel of the present invention and a method of manufacturing the same will be described in more detail with reference to the drawings.

First, a cutting process is performed on a ready-made ALC panel 1 using a rotary blade having a known cross section to form a linear groove 2 as shown in FIG. The shape of this groove is such that even if the side wall of the groove is at a right angle, it is possible to blast this side wall part, but this side wall part is also to be blasted simultaneously with the surface part other than the groove part. It is preferable that the side wall portion be a slightly inclined groove. However, if the inclination is too gentle, the height of the non-cut portion does not appear, so the inclination angle formed by the groove bottom surface and the side surface exceeds 90 degrees,
It is preferable that the angle be 135 degrees or less.

The flaky coating 3 is placed only on the groove bottom 2a processed on the panel surface. The coating 3 is a flaky material made of a material that is not eroded by the projection of a blast material such as a sheet metal or hard rubber.

Thus, only the bottom 2a of the groove 2 was covered with the coating 3.
The ALC panel 1 is, for example, as shown in FIG. 3, a blast material, for example, small steel balls 5 from an impeller unit 4 by ALC.
Processing is performed by projecting toward the panel 1. Due to the projection of the blast material, the portion not covered with the coating material 3, that is, the panel surface 1a other than the groove bottom surface 2a and the groove side surface 2b
Are ground, and the erosion action forms the above-mentioned rough surface with the special irregularities, thereby obtaining the decorative ALC panel shown in FIG.

The type of blast material used in the present invention is not particularly limited. However, as the blast material having a larger particle diameter and density is used, the obtained blasted surface tends to have larger irregularities. From this point, it is desirable to use small steel balls.

(Effect of the Invention) The decorative ALC panel of the present invention is an ALC panel, but a panel having an appearance in which a large number of stones having a sense of thickness are stuck on the surface, and the wall surface constituted by this panel has a split surface. It will be a highly designed wall with a new natural texture that can be mistaken for a stone-stuck wall with a stone.

In addition, since the decorative ALC panel of the present invention has a smooth groove bottom surface, it is possible to penetrate metal fittings such as bolts and screws at this portion and to fix it to a base such as a steel frame as a base. Even if the metal fitting is buried deeper than the groove surface of the panel and then repaired by covering the portion with a repair material or the like, the repaired portion is inconspicuous because the groove bottom surface is smooth. Conversely, since repair marks are conspicuous on the uneven surface portion, it is necessary to avoid penetrating the mounting bracket on the uneven surface portion.

In addition, ALC panels generally have several panels stacked during storage and transport. If the entire surface of the panel is rough, the rough surface of the lower panel is crushed due to the weight of the upper panel, which results in design defects.However, the decorative panel of the present invention has a smooth groove bottom, so By arranging a tall patch in the groove, it is possible to stack panels without crushing the unevenness of the rough surface.

Further, when used as an outer wall material, the decorative ALC panel of the present invention is subjected to a waterproofing treatment with a full-surface primer finish material or an application treatment with another finishing material as necessary. Since the rough surface processed by the material is also ALC itself, no new troubles due to finishing occur.
