PURPOSE:To effectively weld a bracket to a steel pipe without any trouble by a method in which an anticorrosive cover with holes is covered on a steel pipe, the inside of a metal frame fitted into the holes is welded to the steel pipe, and the bent outer edge of the metal frame is joined with the cover through a packing. CONSTITUTION:An anticorrosive cover 2 is covered on a steel pipe 1, a metal frame 9 of an L-shaped cross section is fitted into holes 7, and the outer edges 9a of the metal frame is joined with the cover 2 through a packing 10 by means of bolts. In construction work, a bracket 3 is directly welded to the steel pipe. After the end of construction work, the bracket 3 is removed, a filler is packed in the holes, and a cover 8 is provided. Thus, since the bracket can be directly welded to the steel pipe, the construction work can be made easier. |
