PROBLEM TO BE SOLVED: To enable inclined piping by smoothly moving upper piping materials toward the lower piping materials, while partially changing a piping height.SOLUTION: In a part of an inclined piping adaptor Aconnected to a first protective duct Dvia a T-shaped duct joint J, upper pipes Pand Pin the first protective duct Dare partially curved in side view, and are inclined from the upper stage side to the lower stage side. The upper and lower ends of the pipes Pand Pare fixed to a base body Vvia a fixing tool F so as not to be vertically moved with respect to the first and second fixing surfaces 46 and 47 of the base body V. |
