PURPOSE:To finalize piping installation and wiring work by only laying wiring materials in a concrete structure by using a flexible tubing made of synthetic resin such as combined duct through which a wire is made to pass. CONSTITUTION:Wire drawing work is made on a combined duct(CD) tubing 2 cut into the specified length as a flexible tubing made of synthetic resin. In order to facilitate wire drawing work, it is made with the extended state and a wiring 3 with various diameters and appearance are cut to a length a little longer than the CD tubing 2 before wire drawing work. Then, a wiring material is bent at its end, subjected to other works to make to the specified shape, and finally fitted into a wall 1. Furthermore, when the type and the number of wirings are same, the wiring 3 is drawn in the CD tubing 2 with the full length, and this CD tubing with the wiring drawn in, is made easy to be carried and cut to the specified length and formed near the construction site, and the wiring and piping works are made. |
