【発明の詳細な説明】 産業上の利用分葺 本発明は、形鋼の内面を塗装する方法に関する。[Detailed description of the invention] Industrial use split roof The present invention relates to a method for painting the inner surface of a section steel.
従来技術及びその問題点
一般に形鋼は、条鋼の一種で、断面形状が多角的で比較
的変化に富んだ鋼材を意味し、山形鋼、みぞ形鋼、Ｈ形
鋼、工形禦、球出形鋼等がその例である。Prior art and its problems In general, section steel is a type of bar steel, and refers to a steel material with a polygonal cross-sectional shape and a relatively wide variety of shapes. An example is shaped steel.
このような形鋼は、下記する理由によって、工場塗装、
即ち、「カラー形鋼」への動きが活発化している。This type of steel section is not factory painted or coated for the reasons described below.
In other words, there is a growing movement toward "colored shaped steel."
（ａ）形鋼を使用し、現地加工を行い、その後塗装を行
うことは、経費面、工数面で大きな負担となる。(a) Using shaped steel, performing on-site processing, and then painting is a large burden in terms of cost and man-hours.
（ｂ）現地で塗装を行う場合、塗料ミスト等による現地
周辺への汚染の影響が大きく、対策が大変である。(b) When painting is carried out on-site, the contamination of the surrounding area by paint mist and the like has a large impact, making countermeasures difficult.
このような状況から、形鋼メーカでは、製造ラインに塗
装工程を付加して、形鋼に塗装を施して、市場に供給す
るケースが非常に多くなっている。Under these circumstances, steel shape manufacturers are increasingly adding a painting process to their production lines to coat the shape steel before supplying it to the market.
製造ラインにおいて形鋼を塗装する場合、特にその内面
塗装の際に下記の通りの問題点が生じた。When painting shaped steel on a production line, the following problems arose, particularly when painting the inner surface.
通常、形鋼メーカの製造ラインでは、形鋼は、３０〜８
０ｍ／ｗ＋ｉｎのラインスピード（生産スピード）で製
造されており、これを塗装する方法としては、−ｍに、
エアスプレィ−、エアレススプレィ−等の吹付塗装が行
なわれている。この場合、ラインスピードが速いため、
スプレーガンは固定的に設置される。Normally, on the production line of a shape steel manufacturer, the shape steel is 30 to 8
It is manufactured at a line speed (production speed) of 0m/w+in, and the method for painting it is -m,
Spray painting methods such as air spray and airless spray are used. In this case, because the line speed is high,
The spray gun is permanently installed.
通常、形鋼の内面、例えばリップみぞ形鋼の内面を、塗
り残しなく均一に塗装するためには、多数のスプレーガ
ンを使用することが必要であり、１つのスプレーガンで
形鋼の内面を塗装しようとすると、例えば、リブ部ある
いはコーナ部が適切に塗装できないことが多い、これは
、経験的に実証されている。Normally, in order to uniformly paint the inner surface of a section steel, such as a lip groove section, it is necessary to use multiple spray guns, and one spray gun can coat the inner surface of the section steel evenly without leaving any unpainted areas. Experience has shown that when attempting to paint, for example, ribs or corners often cannot be painted properly.
また、複数個のスプレーガンを使用すると、その管理、
例えば、塗装条件出し、洗浄、メンテナンス等が面倒で
あり、スプレーガン同志の干渉によって、スプレーガン
及び周囲の汚れが著しくなる。また、複数個のスプレー
ガンを使用すると、塗装設備（ブース）も大型になる等
の問題点もある。Also, when using multiple spray guns, managing them,
For example, setting coating conditions, cleaning, maintenance, etc. are troublesome, and interference between the spray guns causes significant dirt on the spray guns and the surrounding area. Further, there are also problems such as the use of multiple spray guns increases the size of the painting equipment (booth).
更に、たとえ多数のスプレーガンを用いたとしても、形
鋼には多くの種類のサイズがあるため、これら総てのサ
イズの形鋼の内面を適切に塗装することは困難である。Furthermore, even if a large number of spray guns are used, it is difficult to properly coat the inner surfaces of all the sizes of shaped steel, since there are many different sizes of shaped steel.
このため、形鋼メーカ及び塗装機メーカは、形鋼の内面
を１つのスプレーガンで適切に塗装する方法を願望して
いるのが現状である。For this reason, the current situation is that shape steel manufacturers and coating machine manufacturers desire a method for appropriately painting the inner surface of a shape steel with a single spray gun.
