Description

Description: TECHNICAL FIELD 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 “ALC panel”) that has been cured by high-temperature and high-pressure steam.

(Prior Art) An ALC panel is a light-weight ready-made panel usually reinforced with a reinforcing material such as a reinforcing steel cage, and is known as, for example, a panel having a width of 60 cm and a length of several meters. this
ALC panels have the characteristics of being excellent in lightness, fire resistance, heat insulation, workability, etc., but the surface of ALC panels is uniform, and the wall composed of ALC panels has a monotonous appearance. I hate it.

Therefore, a panel in which the surface of an ALC panel is partially blasted has been proposed as disclosed in Japanese Patent Application Laid-Open No. 63-25284. In this panel, the surface of the panel is partially blasted to expose the ALC background,
It has a rough surface with irregularities different from the fine irregularities caused by LC bubbles, and this rough surface part is partially present as a concave surface on the panel surface. However, although the surface of the concave part of this panel has a special texture, the concave part is partially dug in a large panel, and if this panel is used to form the wall, It becomes the wall where the eyes go immediately to the size. As described above, it was clear that the wall formed by this panel was constituted by a large panel, and the appearance thereof was also disliked to be monotonous.

In addition, if the number of concave portions formed by blasting is increased in order to eliminate this disadvantage as much as possible, this panel becomes a panel having a large panel and a large number of concave portions formed by blasting. Since the concave portion formed by the blasting process has a substantially uniform depth as a whole, if the wall is formed by using a large number of the panels, an adverse effect such as giving an appearance with a small wall thickness occurs. Therefore, there is a resistance to continuous use of this panel, and in many cases, one panel is used as an accept in a wall composed of a normal ALC panel, and this panel is used less frequently.

(Problems to be Solved by the Invention) The present invention has a disadvantage that a conventional decorative ALC panel has an appearance such that it is made of ALC, so that only a monotonous wall surface can be obtained. It eliminates the drawback of being a panel that is resistant to use, and even if a large wall is constructed by using a large number of ALC panels of one type, it gives a wall with a new complex design, It is another object of the present invention to provide a cosmetic ALC panel in which the size of each panel is not easily noticed, and to provide a method of manufacturing the panel.

(Means for Solving the Problems) The decorative ALC panel of the present invention is entirely composed of the same ALC, has a rough concave portion formed by blasting on the panel surface, and is formed of a wire in a plastic state during manufacturing. A surface other than the concave portion having the same surface property as the cut normal ALC panel surface exists surrounding the concave portion as a convex portion, and a groove having a flat bottom surface cut with a cutting tool is formed in the convex portion. It is characterized by being.

Further, the method of manufacturing a decorative ALC panel according to the present invention is characterized in that a groove having a flat bottom surface is cut at a predetermined position on a surface of a normal ALC panel cut with a wire in a plastic state at the time of manufacturing with a knife, and then a predetermined groove other than the groove is formed A template having a pattern opening at a position is placed on the surface of the ALC panel, a blast material is projected from the template, and the surface of the ALC panel at the opening of the template is eroded.

That is, as shown in FIG. 1, for example, the decorative ALC panel 1 of the present invention has a partially rough concave portion 2 and also has a groove 3 on which the concave portion 2 and the groove 3 are formed. In addition to this, the panel has a convex portion 1a on the surface. Concave part 2 of this rough surface
The inner surface is the surface that has been eroded by blasting material,
It is a rough surface with irregularities different from the fine irregularities due to ALC bubbles. The surface characteristics of the concave portion 2 give an impression similar to the peculiar stone skin obtained only when blasting is applied to ALC. The groove 3 is a surface cut by a cutting tool, and is a surface on which the ALC ground surface is exposed although there are fine pores of ALC. As described above, one of the two types of concave surfaces (concave surface 2 and groove 3) has a surface texture similar to that of stone, and the other has an artificially flat surface texture, and the design is more emphasized in comparison between the two. It is highly likely. Further, the convex portion 1a
Is a surface having a surface property different from the surface properties of the above-described two types of concave portions, that is, a surface that retains the surface properties of a normal ALC panel.

As described above, the decorative ALC panel 1 of the present invention has two kinds of concave portions having significantly different surface properties, that is, the rough concave portion 2 and the groove 3, and in that respect, the design is also high. In addition, a convex portion 1a having a surface property different from those of these two types of concave portions is provided between them.
Therefore, the pattern on the panel surface can be further raised.

As described above, since the groove 3 of the smooth surface provided in the decorative ALC panel of the present invention has a surface property that is difficult to distinguish from the joint between the panels, the wall surface is formed using the decorative ALC panel of the present invention. Then, a small ALC block having a concave part giving an impression similar to the stone-cut skin (in the example shown in FIG. 1, the ALC of the smallest unit having one blasted concave part in the middle
Blocks) are attached, and the conventional ALC panels do not become conspicuous monotonous walls,
In addition, the wall surface gives an impression as if partly using a stone material having split skin.

Such a decorative panel is a template having a pattern-shaped opening that can cover a groove and a desired portion around the groove after cutting a groove with a flat bottom at a predetermined position on the surface of the ALC panel with a blade. Mask the surface of the ALC panel using, and project the blasting material from the template onto the ALC at the opening of the template.
It is obtained by eroding the panel surface.

That is, a groove is cut at a predetermined position on the surface of the ALC panel using a blade, for example, a rotary blade, and thereafter, the groove and a desired portion are covered, and the panel is formed by a template having a pattern-shaped opening. By blasting a conventionally known blast material, for example, a large number of small steel balls, onto the ALC panel, and eroding the panel surface other than the template covering portion.

In addition, the order of the cutting of the groove by the cutting tool and the erosion processing by the projection of the blast material may be reversed, and after the blast processing is performed first, the groove may be formed at a desired position of the non-blasted portion by the cutting with the cutting tool.

If the groove is cut with a blade first, the ALC panel can be used as a decorative panel with a tile pattern even when blasting is not performed. It is preferable to fabricate a decorative ALC panel by processing the surface.

Hereinafter, a decorative ALC panel according to an example of the present invention will be described in more detail with reference to the drawings, using an example of a method for manufacturing the panel.

The ALC panel 1 shown in FIG. 2 is a normal ALC panel surface cut by a wire in a plastic state at the time of manufacturing, and is cut by a normal rotary blade to form a linear bottom surface at a desired position on the surface. Is a panel on which flat grooves 3 are formed. The ALC panel 1 is placed on a conveyor for blasting as shown in FIG. 3, and a template 4 is placed on the surface of the panel 1. This template 4 is provided with a rectangular opening 5 drilled with a sharp blade over the entire surface of the template.
It has a design pattern. The material of the template 4 may be steel, but it is preferable because hard rubber is less warped, adheres tightly to ALC, and drilling work is relatively easy.

As shown in FIG. 3, the blast material 7 is projected from the impeller unit 6 onto the ALC panel 1 covered with the template 4. In this projection, it was preferable that the blast material be uniformly projected on the panel. By the projection of the blast material 7, the portion not covered by the template 4 is ground, and the erosion action of the blast material 7 becomes the concave surface portion 2, and the above-mentioned rough surface having the special unevenness, that is, the splitting of the stone material A rough surface similar to the skin is formed, and the surface as illustrated in FIG. 1 is a decorative ALC panel including the concave portion 2, the convex portion 1a, and the groove 3.

The type of the blast material used at this time is not particularly limited, but as the blast material having a larger particle diameter and density is used, the obtained blasted surface tends to have larger irregularities. In this regard, the use of small steel balls is particularly preferred.

Further, in the decorative ALC panel of the present invention, the groove 3 can be provided at an arbitrary position without departing from the spirit of the invention. For example, as illustrated in FIG. 1, a straight groove 3 may be formed so as to surround the concave portion 2 except for the concave portion 2 and the subsequent convex portion 1a. Makeup AL configured in this way
The C panel is a panel having a surface property in which a large number of small panels with a rough surface having special irregularities formed by blasting or the like are attached. At this time, the size of the concave portion 2 is not made uniform, and as shown in FIG.
Further, if the area surrounded by the groove 3 is different in size, a decorative ALC panel having a different design will be obtained.

Furthermore, if a panel having a straight groove 3 surrounding the concave portion 2 is used for the wall surface, leaving the concave portion 2 and the subsequent convex portion 1a, the rainwater flowing down from the upper portion does not flow into the concave portion, It is possible to drain the water quickly through the joints between the grooves and the panels, so that the penetration of water and the generation of moss and the like at the concave portion can be extremely reduced.

(Effects of the Invention) (1) The surface of the decorative ALC panel of the present invention is (1) a normal ALC panel surface formed by cutting a wire rod during manufacturing; (2) a groove formed by cutting with a cutting tool; And a concave surface part which is roughened.
Then, (2) gives an impression similar to the joint of tiles artificially and linearly, (3) gives an impression similar to the split skin of stone,
(1) forms a convex portion, and (2) and (3) form two types of concave portions.

Therefore, although the cosmetic ALC panel of the present invention is composed entirely of the same ALC and has no color difference in itself,
Makeup ALC with beautiful special patterns with various irregularities on the panel surface and various patterns due to differences in surface properties
Panels are provided. And (1), (2), (3)
The makeup ALC panel having a more complicated special pattern can be provided by changing the arrangement and the area of the ALC panel in various ways.

(2) In the decorative ALC panel of the present invention, since the groove bottom is smooth, metal fittings such as bolts and screws are made to penetrate in this portion,
It is possible to fix it to the foundation such as steel frame, and even if these fittings are buried deeper than the groove surface of the panel, and then the parts are covered with a repair material or the like for repair, the bottom of the groove Has a merit that the repaired portion is inconspicuous because the surface is smooth. (Conversely, repair marks are conspicuous on uneven surface parts, so penetration of the mounting bracket on uneven surface parts should be avoided.)
