ABSTRACT:
Expansion gaps formed between bellows type side walls of evacuated heat ilating wall components of gas and pressure-tight containers are sealed by elastically deformable corrugated expansion sheet metal strips welded to the surfaces of neighboring wall components, and by specially shaped junction covers secured in a gas-tight manner to the wall components and to the strips. The covers have a central cavity and ondulating depressions merging into corrugations of the sheet metal strips. The expansion gaps are also evacuated and filled with a suitable insulating material. Mechanically loadable support elements may be located in the expansion gaps.
