STEEL COLUMN WITH COATING LAYER AND CORROSION-PROOFING METHOD FOR EXISTING STEEL COLUMN
PROBLEM TO BE SOLVED: To provide a steel column with a coating layer that offers excellent anticorrosion performance nearby the ground, and a corrosion-proofing method for an existing steel column that provides an excellent corrosion protection work nearby the ground.SOLUTION: A steel column with a coating layer has a corrosion-proofing work performed at a part nearby the ground, and has an anticorrosive layer, an adhesive layer and an anti-corrosion metal layer, in that order, on a main surface nearby the ground of the steel column, and furthermore has two edge part seals that respectively cover upper and lower edge surfaces of the anti-corrosion metal layer. A surface roughness (Ra) of the anticorrosive layer is 10 μm or less. The edge part seal does not adhere to the steel column, but instead adheres to a main surface of the anticorrosive layer and a main surface of the anti-corrosion metal layer, where each of the adhered parts measures 30 mm or more in a longitudinal direction of the steel column.
【課題】地際部において防食性に優れる被覆層付き鋼製柱、および既設鋼製柱における地際部を高度に防食施工することができる防食施工方法の提供。【解決手段】地際部に防食加工が施された被覆層付き鋼製柱であって、鋼製柱の地際部の主面に防食層、接着層および耐食性金属層をこの順に有し、さらに前記耐食性金属層の上下両端面の各々を覆う２つの端部シールを有し、前記防食層の主面の表面粗度（Ｒａ）は１０μｍ以下であり、前記端部シールは前記鋼製柱とは付着せずに、前記防食層の主面および前記耐食性金属層の主面に付着していて、その付着部分は、前記鋼製柱の長手方向において、各々３０ｍｍ以上である、被覆層付き鋼製柱。【選択図】図１
