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 an outer peripheral surface of a pillar structure 1 comprising a smoothing means, and a nozzle 12b having an opening 12c for supplying a coating material; the opening 12c being disposed nearly at the same position as that of the upper end portion 1e of the structure 1 in nearly vertical direction of the structure when being held for coating, and having a length of the longer direction shorter than the length between the both ends of the structure 1. The coating material is supplied from a nozzle 12b to the outer peripheral surface 1a of the structure and coating it on the outer peripheral surface 1a while smoothing the coating surface by a smoothing means 10. The coated surface of the structure is protected from cracking during drying after coating and it is free from defects. A coating method using the apparatus is also provided.
