<p><P>PROBLEM TO BE SOLVED: To provide an air-conditioning duct whereby the duct length conventionally restricted in some physical distribution can be made a long size, by easily molding a pipe by anybody by a simple auxiliary tool, by further realizing flexibility, thermal insulation performance and weight reduction, by not only compressing physical distribution cost but also adjusting a construction material, a width and the thickness in a resin belt-like part of a resin belt-like body, by easily molding the pipe even at a job site. <P>SOLUTION: This resin belt-like body is composed of the resin belt-like part of an optional width and female-male fitting parts arranged in parallel on it side edge. The resin belt-like body and a fitting auxiliary tool can mold the pipe in a spiral shape, by inserting the male fitting part into the revolved female fitting part. A resin spiral duct is molded by using these. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
