Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prismatic spiral duct structure, a method of using the prismatic spiral duct structure, and a method of manufacturing the prismatic spiral duct structure.

[0002]

2. Description of the Related Art Conventionally, the present inventor has conducted extensive research into the manufacture of spiral ducts, established a high-efficiency spiral duct manufacturing system, and actually used the high-efficiency spiral duct manufacturing apparatus. I have been working hard to make products.
However, all products have been manufactured using spiral ducts with circular cross sections. However, in ducts related to ventilation, heating, ducts related to air conditioning used for both heating and cooling, and other ducts, the demand for spiral ducts with a circular cross section does not exceed 30% of the total demand for ducts. The demand for the remaining ducts is the demand for the ducts of the rectangular tubular structure. However, the manufacturing method of the duct of the rectangular tubular structure has not been improved for a long time, and the galvanized iron plate is bent by sheet metal working, and the connecting portions of the both ends of the bent galvanized iron plate are opposed to each other. They are attached by attaching them, transported from the factory to the construction site, and assembled at the construction site. Therefore, the fare from the factory to the construction site was not easy.

[0003]

Therefore, research has been conducted to reduce the cost of transporting the duct of the rectangular tubular structure from the factory to the construction site. Therefore, first of all, we acquired the technology to make the circular spiral duct expandable, and put it into practical use. However, if the cross section is circular, there will be a gap and the fare cannot be reduced. Therefore, we considered manufacturing a spiral duct with a rectangular cross section. Next, the inventors of the present invention have made efforts to develop a manufacturing technology for a spiral duct having a rectangular cross section by applying the manufacturing technology for a spiral duct having a circular cross section. I found a possibility to do it. Then, like the case of manufacturing a spiral duct having a circular cross section, the material was used as a strip plate of a steel plate, iron plate or other rigid metal plate, and an attempt was made to manufacture a spiral duct having a rectangular cross section. Then, using the strip plate as a raw material, a spiral duct manufacturing apparatus having a circular cross section was improved, and a spiral duct having a rectangular cross section could be manufactured by the improved spiral cross section manufacturing apparatus. Therefore, by combining these technologies, a rigid metal plate or the like is used as a material for the strip plate, and a method of manufacturing a rigid rectangular tubular structure using the material and a rigid rectangular tube manufactured by the manufacturing method. It is an object of the present invention to provide a method of using a tubular structure and its rigid rectangular tubular structure.
