Claims (1)
で真空化して成る断熱管の管端部の前記二重壁を
密封するメンブレンが、雌雄関係をなして相互に
嵌合可能な凹凸曲面とされ、互いに突き合わされ
た前記断熱管の外壁管同志が相互に機械的に接合
されていると共に、内壁管は熱膨張により伸長可
能なよう外壁管よりやや短尺とされ、かつ、前記
メンブレンの凸曲面の形状が内壁管の膨張伸長し
た際、変化する曲率半径が前記一方の断熱管の凹
入メンブレンの曲率半径に略等しくなるよう構成
して成ることを特徴とする断熱管の接続構造。 A concavo-convex curved surface that allows the membranes that seal the double wall at the end of the insulated tube, which is formed by filling a sealed double-wall space with a heat insulating material and then evacuating it, to be able to fit into each other in a male-female relationship. The outer wall tubes of the insulating tubes that are butted against each other are mechanically joined to each other, and the inner wall tube is slightly shorter than the outer wall tube so that it can be expanded by thermal expansion, and the convexity of the membrane is A connecting structure for heat insulating pipes, characterized in that the shape of the curved surface is configured such that when the inner wall pipe expands and expands, the radius of curvature that changes is approximately equal to the radius of curvature of the recessed membrane of the one heat insulating pipe.
