WATER SUPPLY/HOT WATER SUPPLY PIPING AND SPRINKLER FIRE EXTINGUISHING PIPING SYSTEM, AND ITS PIPING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a water supply/hot water supply piping and sprinkler fire extinguishing piping system for simultaneously laying loop pipes for water supply/hot water supply piping and a loop pipe for sprinkler fire extinguishing piping at one part of a ceiling.;SOLUTION: The loop pipes 1 and 2 for the water supply/hot water supply piping in which the main pipes 4 and 8 of the water supply/hot water supply piping are connected to a part of them and branching pipes 6 and 10 are connected to other several parts and the loop pipe 3 for the sprinkler fire extinguishing piping in which the main pipe 12 of the sprinkler fire extinguishing piping is connected to a part of it and a branching pipe 14 is connected to other several parts are formed in the same or roughly the same outer diameter. The loop pipes 1 and 2 for the water supply/hot water supply piping and the loop pipe 3 for the sprinkler fire extinguishing piping are vertically piled up and integrally combined concentrically at prescribed intervals in a vertical direction to form a loop piping unit 17, and the loop piping unit is laid on the ceiling.;COPYRIGHT: (C)2008,JPO&INPIT
