囲第１項に記載の空調・換気用ダクト。[Scope of Claim for Utility Model Registration] (1) A rigid foam board with an appropriate thickness that has excellent mechanical strength and heat insulation properties, exhibits little change in volume and does not become brittle even when exposed to high temperatures, and is folded into a box shape. The duct body is bent and bonded to form a duct body having uneven fitting parts for duct connection at both lengthwise ends, and an exterior material made of a composite sheet material of glass cloth and aluminum thin film is covered and bonded to the outer periphery of this duct body. air conditioning and ventilation ducts. (2) The rigid foam board is made by adding an organic solvent to an inorganic powder and moistening it to make a wet powder A, separately mixing a vinyl chloride resin powder and an inorganic fiber agent to make a mixture B, and combining the wet powder A and the mixture B. This product is obtained by foam-molding a sol-like product obtained by adding an organic solvent and liquefied butane to this mixture using a conventional method. A stepped notch on the inner surface of one end and a stepped notch on the other end to form a V-shaped groove for bending and to form a concave-convex fitting part for duct connection at both lengthwise ends of the board body. A stepped notch is provided on the outer surface side, and a stepped notch is provided on the inner side for forming a box closing joint surface on one side of the board body, and the cut surface of the V-shaped groove and one side of the board are provided with a stepped notch on the inner side for forming a box closing joint surface. Utility model registration claim 1, characterized in that a duct body with a desired cross-sectional dimension is constructed by applying an adhesive to the step-like notched surfaces of the sides, bending this board body into a box shape, and gluing it together. Air conditioning/ventilation ducts as described in section.
