    • PROBLEM TO BE SOLVED: To provide a duct and a duct connection structure, free from coming off between flange parts formed by making ducts be butted against each other even by load of an earthquake or the like, and capable of preventing displacement of a connection part between the flange parts.SOLUTION: In ducts 1 and a duct connection structure, the cylindrical ducts 1 each formed by arranging wall plates 10 in four sides are connected to each other so that opening ends of the ducts are brought into contact with each other. A projected fitting part 12 made by bending the wall plates 10 and extending along an opening edge is formed in the opening end part of one of the duct 1 and a recessed part 13 to be fitted made by bending the wall parts 10 and extending along an opening edge is formed in the opening end part of the another duct 1 and the one duct 1 and the another duct 1 are connected by fitting the fitting part 12 into the part 13 to be fitted.
    • 要解决的问题:为了提供一种管道和管道连接结构,即使在地震等的负荷下,通过使管道彼此对接而形成的凸缘部之间不会脱落,并且能够防止连接部的位移 在管道1和管道连接结构之间,通过在四个侧面设置壁板10形成的圆柱形管道1彼此连接,使得管道的开口端彼此接触。 通过弯曲壁板10并且沿着开口边缘延伸而形成的突出的嵌合部分12形成在管道1中的一个的开口端部分和待装配的凹入部分13中,该凹部13通过弯曲壁部10并沿着 开口边缘形成在另一个管道1的开口端部,并且一个管道1和另一个管道1通过将装配部分12装配到待装配的部件13中而连接。
