Title: Piping structure
Inventor: FUJII TOSHITSUNA
IPC: F16L25/00
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To absorb the vertical and lateral errors in construction by setting the upstream inside diameter of a piping member larger than the downstream outer diameter, in the formation of a drain pipe by mutually connecting a plurality of piping members, and connecting a downstream piping part to an upstream piping part through a watertight member. SOLUTION: The upstream inside diameter 1a of a piping member 1 is set larger than the downstream outside diameter 1b. A drainpipe is formed by connecting a plurality of piping members 1 and connecting a downstream piping part 1d to an upstream piping part 1c through a watertight member 2. The reason of setting the upstream inside diameter 1a of the piping member 1 larger than the downstream outer diameter 1b is that the force against the drain flow is eliminated. According to this, since the clearance between the upstream inside diameter 1a and downstream outer diameter 1b of the pipings 1 is blocked by the watertight member 2 when the piping members 1 are mutually connected, the watertight member 2 can work as a slide part to absorb the center slippage.
