摘要

PURPOSE: To improve updating execution workability by manufacturing an renewal piping material, wherein a plurality of branch pipes are connected to a header of providing a socket of connecting a primary side pipe, in a factory, setting up this material in a job site, and cutting each branch pipe into a required length connected to an existing equipment. ;CONSTITUTION: At execution time, first in accordance with a piping route shown by an execution drawing, setting out is performed to drill a hole in a wall through part by using a hole saw or the like in a predetermined position. Next in accordance with the set out piping route, a base 64 of a case way 60 is fixed and also fixing a head box 58, built with an renewal piping material, to a predetermined position. The other end of a hard vinyl chloride pipe 24, with its one end communicating with a city water meter, is connected to a receiving port of a socket 26. Next, each branch pipe 46 (46a to 46d) drawn out from the head box 58 is arranged along the base 64, to also fit a cover 66 to the base 64, and after cutting each branch pipe 46 into a necessary length to perform an air-tightness test of each connecting part, an end part of each branch pipe 46 is connected to an existing equipment of a seat-provided washing elbow or the like.;COPYRIGHT: (C)1994,JPO&Japio
