Apparatus for coating outer peripheral surface of pillar structure and method for coating outer peripheral surface of pillar structure

摘要

An apparatus for coating the outer peripheral surface 1a of a pillar structure 1 comprising a smoothing means 10 having a smoothing plate 10a and an elastic body 10b; the elastic body 10 being disposed to be contacted with the outer peripheral surface 1a of the pillar structure 1 to be coated. The coating surface of a coating material supplied to the outer peripheral surface 1a is smoothed between the outer peripheral surface 1a and the elastic body 10b. A method for coating the outer peripheral surface of a pillar structure is also provided. According to the method by using the apparatus, the occurrence of partial uncoating or peeling of the coating and occurrence of cracks in the coating portion during drying after coating can be inhibited since the coating material can be applied thinly and uniformly on the outer peripheral surface, thereby the coating surface is smoothed.
