Abstract

PROBLEM TO BE SOLVED: To prevent a down pipe from getting dirty owing to accumulated dust on a fixing metal tool with rainwater, by protruding outward both edges of the cylindrical down pipe body to form an inverted V-shape and providing a fixing part at the front end and having the fixing part holded by the fixing metal tool to fix it to a building. SOLUTION: Both edges 11a, 11b of a down pipe body 11 that a metallic belt-form plate is cylindrically shaped, are folded outward to provide an inverted V-shaped joint 12 and form a down pipe having a letter ohm-shaped cross section. And further, the front end sides of both edges 11a, 11b are bent oppositely to each other and bent again form a hair pin-shape to make fixing parts A, B having an L-shaped section. And then, the fixing part 13a of the first fixing metal tool 13 with a T-shaped cross section is fixed to a building with nails or the like. And the fixing parts A, B of the down pipe 10 are held by holders 14a, 15a with a U-shaped cross sectional face of the front end of the second fixing tools 14, 15 and the projection 13b of the first fixing metal tool is held by the basal part thereof and integrally combined with bolts and nuts. Since the fixing metal tool does not traverse the surface of the down pipe body 11, there is no fear that piled dust on the metallic tools 13-15 flows with rainwater and contaminates the down pipe.
