Document Type and Number:
Japanese Patent JP6838500
Kind Code:
B2
Abstract:
To provide a double heat insulation wall structure which can suppress the breakage of a bellows caused by decentering at heating.SOLUTION: In this double heat insulation wall structure being a double heat insulation structure 1 in which a sealing space 14 between an outer pipe 11 and an inner pipe 12 is decompressed, the outer pipe 11 and the inner pipe 12 are arranged so that axial directions become vertical to a vertical direction, the outer pipe 11 and the inner pipe 12 are joined to each other at both end parts via a bellows B, a support member 13 contacting with the outer pipe 11 is arranged at a vertical lower side of the sealing space 14, the bellows B is arranged in an elongated state so that tension is applied to the inner pipe 12 in an axial direction in a non-heated state, and the support member 13 and the inner pipe 12 oppose each other with a prescribed interval in a radial direction.SELECTED DRAWING: Figure 1
