DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ALC panel in which a large number of shot materials are projected onto a lightweight cellular concrete (hereinafter abbreviated as ALC) panel through a template on a pattern. The method of processing.

[0002]

2. Description of the Related Art When a pattern is formed on a surface of an ALC panel by a shot blast method through a rubber template formed into a pattern such as a character, a picture, and a pattern, the method of installing the template is as follows. On the ALC panel, or fix it to the ALC panel by partially nailing it from the upper part of the template, or press the template from the upper part of the template using a simple frame made of steel. The method of fixing on the top was used.

[0003] On the other hand, not only ALC panels but also concrete blocks, plastics, glass, wood, etc. are sprayed through the template by a shot blast method or a pulverized cutting material such as sand, slag or wire cut by air pressure or water pressure. In the case of patterning, a method has generally been used in which a template is directly adhered and fixed on a workpiece with an adhesive.

[0004]

When processing with a projection material using the conventional method of installing a template, when fixing with a nail or an adhesive, it takes a lot of time to install and remove the template. Then, marks such as nail holes remain on the surface of the ALC panel. On the other hand, the method of merely placing the template on the ALC panel cannot withstand the impact force of the projection material during the processing of projecting a large number of projectiles, and the template shifts or floats during the processing. AL that accurately reflects the pattern drilled into the hole
There is a problem that C cannot be processed. or,
If a steel material is used on the upper part of the template to hold down the template, the shot material is also projected on the steel material and is deformed, so that the pattern shifted from the template also cannot be accurately processed.

[0005]

According to the present invention, a template having a pattern-shaped notch is placed on an ALC panel, and a projection material is projected from above to form a pattern under the notch of the template. AL
In a method of processing an ALC panel by grinding and eroding a C panel, an auxiliary member is brought into close contact with at least two opposite sides of the ALC panel, covered with a template up to the auxiliary member, and fixed to the auxiliary member. A method for processing an ALC panel.

The present invention is effective even if the thickness of the ALC panel manufactured in the present invention is 37 to 150 mm and reinforced with either a lath net or a reinforcing bar. The notch of the template used in the present invention may be any pattern, and may be, for example, any of letters, pictures, and designs. The material of the template is not particularly limited, but a conventionally used rubber template is preferable from the viewpoint of easy notch and abrasion of the shot material. Further, in the present invention, the template can be firmly fixed to the mold steel material and the ALC panel, and even if a thin template is used, no displacement, abrasion, or wrinkling occurs at the time of projection, so a template having a thickness of 1 mm or more is used. Can do things.

The blasting material used in the present invention may be a material used for sandblasting or a material used for shot blasting. In particular, a product obtained by using a small steel ball as a projection material has irregularities even in a portion that has been ground and eroded, and is excellent in design. Therefore, it is desirable to select a small steel ball as a projection material. The auxiliary member used in the present invention is disposed in close contact with the small face of the ALC panel, and may be made of any material, for example, any one of mold steel, wood, and plastic. Shape steel is desirable from the viewpoint of weight and rigid connection. Further, the height of the auxiliary member is preferably substantially equal to the thickness of the ALC panel, and the auxiliary member may be at least in close contact with the long side of the small edge surface. The effect of the present invention is further increased. In order to come into contact with the four circumferences in this way, as shown in FIG. 3, of the mold steel materials constituting the auxiliary member, the mold steel material 2a contacting in the long side direction is lengthened, and the mold steel material 2b contacting the edge of the end face is fitted. In this case, when processing panels having different lengths, it is not necessary to prepare auxiliary members having different lengths. The mold steel material is, for example, one having a thickness of 0.8 mm or more and covers almost the entire front surface of the ALC panel, and a material having a certain width or more, for example, 15 mm or more in close contact with the mold plate. Various shapes such as those having a square cross section can be used.

Further, the template is fixed to the auxiliary member. This fixing method is, as shown in FIG.
The mold plate 3 may be fixed to the mold steel material 2a as an auxiliary member, or as shown in FIG. 4, the mold plate 3 may be fixed to the mold steel material 2a having a square cross section as an auxiliary member using an adhesive. Even if the auxiliary member and the template are fixed in this way, they are not fixed to the ALC panel, so they can be removed from the processed surface, the ALC panel can be separated from the auxiliary member and the template, and the next ALC panel can be set. , Can be processed by projection. There may be any gap between the short-side mold steel and the short side edge of the ALC panel. However, if they are arranged closely, the adhesion between the mold steel, the mold plate and the ALC panel is improved, and the A when projecting
It is preferable because there is no displacement or unevenness of the LC panel.

[0009]

1 and 2, an embodiment of the present invention will be described. First, FIG. 1 conceptually shows a template setting method for carrying out the present invention. Two long-side mold steel members 2a connected by the short-side mold steel member 2b are arranged in contact with the long-side small-face surface of the ALC panel 1, and sandwich the ALC panel 1. The bolts 8 fixed to the short-side steel member 2b by welding pass through the loose holes of the long-side steel member 2a, thereby connecting the long-side steel member 2a and the short-side steel member 2b.

The ALC panel 1 used in this embodiment has a thickness of 5
0 mm, reinforced with a lath mesh,
“a” is a steel material having a thickness of 0.8 mm and a 50 mm × 50 mm L-shaped cross section. The surface of the ALC panel 1 and the mold steel 2a,
The surface on which 2b is projected is covered with a rubber mold plate 3 having a thickness of 5 mm, and the mold plate 3 is fixed to the mold steel 2a by bolts 4 protected by rubber.

Thereafter, a large number of cylindrical projection materials 7 having a diameter of 1.2 mm and a length of 1.8 mm are projected from the impeller unit 6 arranged above the ALC panel 1 over a width of 600 to 900 mm at a projection speed of 30 to 85 m /. Seconds, projection density 20 ~
Project at 100 kg / m ² . As a result, the projection material is projected onto only the portion of the surface of the ALC panel 1 corresponding to the pattern hole 5 of the template 3, and the ALC panel surface is patterned. As a result, in the present embodiment, even if shot blasting is performed using a large-diameter projection material that is particularly likely to move when the projection is performed without fixing the template, in the present embodiment,
Was formed on the ALC panel.

[0012]

According to the present invention, the template is fixed to the auxiliary member which is closely attached to the two sides of the ALC panel, and the template is cut into the template without shifting or floating during panel processing. Perforated patterns can be accurately and efficiently processed. Furthermore, since the auxiliary member is arranged in contact with the panel fore face, it does not hit the fore face, so that the projection material is processed into the fore part of the ALC panel. ALC without damage and conventional projection processing
Panels can be constructed using the same construction method as panels.
