[I-396] A Proposal of Paint Coating Removal Method by Heating for High Strength Bolted Joints in Steel Bridges
Keywords:Maintenance, Anti-corrosion painting, Paint coating removal, High strength bolt, Heating
A technology has been investigated for removing deteriorated paint coating by heating at a relatively low temperature using ceramic heaters. In this paper, using a heating device applied to high strength bolted joints, a paint coating removal experiment was carried out on a specimen with a large number of bolts. From the viewpoint of workability and prevention of relaxation of the bolt, a heating temperature for paint coating removal was set to 200 degrees, and a method of applying heating and paint coating removal in parallel.
