PROBLEM TO BE SOLVED: To provide a vertical pipe piping method capable of safely and smoothly piping a piping unit as a vertical pipe of a multistory building. SOLUTION: A guiding short pipe having an outer diameter smaller than a through-sleeve diameter and having an inner diameter larger than the piping unit, is successively received from below by a lower side guiding short pipe at the lowest story for piping. A guide cylindrical body having the upper end reaching above a through-sleeve of the uppermost story for piping and having a leading linear material taking-out clearance on the lowest story side is formed. After inserting the piping unit into this guide cylindrical body, the guiding short pipe is successively removed from the lower end side of the guide cylindrical body. COPYRIGHT: (C)2008,JPO&INPIT
