PURPOSE: To stack assemblies of the same shape in two positional relationships by fixing an outer surface of one outer gutter body to a first support body, and fixing an outer surface of the other outer gutter body to a second support body. CONSTITUTION: Same leg bodies 8, 9 are welded to a part close to the end part of an outer wall body of a gutter body 1 to form a first support body 10, and same leg bodies 11, 12 are welded to an outer wall body of a gutter body to form a second support body 13. In the support bodies 10, 13, the leg bodies are inclined in the longitudinal direction so as to be expanded downward, and the leg bodies 8 and 9, 11 and 12 are welded respective to rods 14 and 15. Abutting bodies 16, 22 are provided on an end part of the rod 14 and close to an end part of the rod 15, and the abutting part 22 is higher than the abutting body 16. A locking projecting piece 19 is provided on the leg bodies 8, 9 and a locking projecting piece 28 is provided on the leg bodies 11, 12. When the support body 10 is lapped on the support body 10, the locking projecting piece 19 is abutted on the abutting body 16, and the locking projecting piece 28 is abutted on the rod 15. When the support body 10 is lapped on the support body 13, the locking projecting piece 19 is abutted on the abutting body 22, and the locking projecting piece 28 is abutted on the abutting body 16. |
