先ず、第7図に示すようにALCパネル1の表面と小口
面とが交差する縁部22に、約45度に傾斜した一つの平面
よりなる単純な面取面28を形成する。First, as shown in FIG. 7, a simple chamfered surface 28 composed of one plane inclined at about 45 degrees is formed at an edge 22 where the surface of the ALC panel 1 intersects with the fore-edge surface.
次に、第8図に示すように該ALCパネル1の表面にそ
の真上から塗料をスプレー塗布する。このとき、該塗料
はALCパネル1の表面に厚く付着するが、傾斜した面取
面28には少ししか付着しない。そこで、第9図に示すよ
うに、高粘度(70〜100ポイズ)の塗料を吹付けること
により塗料の流動を防ぎ、面取面28、角部26,27の膜厚
を所定厚さ以上に確保しているが、膜厚が厚いため面取
面28等に波模様が生じてその凹凸が大きくなりやすい。Next, as shown in FIG. 8, a paint is applied to the surface of the ALC panel 1 from directly above. At this time, the paint adheres thickly to the surface of the ALC panel 1, but only slightly adheres to the inclined chamfered surface 28. Therefore, as shown in FIG. 9, the flow of the paint is prevented by spraying a paint having a high viscosity (70 to 100 poise), and the thickness of the chamfered surface 28 and the corners 26 and 27 is set to a predetermined thickness or more. Although it is ensured, since the film thickness is large, a wavy pattern is generated on the chamfered surface 28 and the like, and the unevenness tends to be large.
また、上記のようにして形成された面取面28上の塗料
層24の表面は曲面とはならず、表面と面取面28との交差
する角部26及び面取面28と小口面との交差する角部27付
近には、外部から明らかに観察される稜線23,29が形成
される。Further, the surface of the paint layer 24 on the chamfered surface 28 formed as described above does not have a curved surface, and the corner 26 where the surface intersects the chamfered surface 28 and the chamfered surface 28 and the fore-edge surface. Ridges 23 and 29 that are clearly observed from the outside are formed near the corner 27 where.
[発明が解決しようとする課題] ところが、上記の方法により得られた化粧パネルは、
第7図に示すように、前記塗料層24に形成される前記稜

一でなく、縁部22の長手方向にみたときの塗膜の厚さが
不均一になり、前記稜線23が上下又は左右方向に波うつ
のである。面取面28と小口面の交差する角部27におい
て、稜線29が波うつのも同様の原因による。The waves on the ridgelines 23 and 29 are considered to be due to the following causes. That is, in the coating step shown in FIG. 9 described above, since the angle between the surface of the panel 1 and the chamfered surface 28 is large, the thickness of the coating film is not uniform near the corner 26 and The thickness of the coating film when viewed in the longitudinal direction of the portion 22 becomes non-uniform, and the ridge line 23 is wavy in the vertical or horizontal direction. At the corner 27 where the chamfered surface 28 and the fore-edge surface intersect, the ridgeline 29 is wavy due to the same cause.
また、上記塗膜の厚さが不均一なので、各稜線23,29
の直ぐ下方には塗料層24の薄い部分が生じ、化粧パネル
25全体の防水性や耐久性が低下するおそれもあった。Further, since the thickness of the coating film is not uniform, each ridge line 23, 29
Immediately below, a thin portion of the paint layer 24 occurs, and the decorative panel
There was also a risk that the waterproofness and durability of the entire 25 would be reduced.
