Abstract

In a heat-insulating structure conisting of stacks of metallic modular elements placed in imbricated relation by means of overlapping edge portions, each stack is assembled by means of a single fastening member which is passed right through; and each modular element comprises a leak-tight chamber divided into two equal compartments having the shape of right-angled parallelepipeds, overlapping edge portions formed by the compartments which are relatively displaced along one diagonal, a spacer member fixed between the large bearing faces of the chamber and a filling structure within each compartment.

Claims

1. A heat insulating apparatus comprising a plurality of metallic modular members each defining two stacked compartments, each compartment having the shape of a right-angled parallelepiped, said compartments communicating through a common internal face defining overlapping edge portions, said members being disposed in a stacked relationship with their respective edge portions extending in an imbricated relationship, a tie bolt extending through said tubular member, a pressure plate engaging the outermost member and cooperating with said tie bolt to clamp said members in said stacked relationship, and a tubular member extending perpendicular to and attached to said members and cooperating with said tie bolt for maintaining said members in a predetermined alignment.

2. A heat insulating apparatus comprising a plurality of metallic modular members each defining two stacked compartments, each compartment being maintained in a vacuum and each having the shape of a right-angled parallelepiped, said compartments communicating through a common internal face defining overlapping edge portions, said members being disposed in a stacked relationship with their respective edge portions extending in an imbricated relationship, fastening means for fastening said members in a stacked relationship, and means extending perpendicular to and attached to said members for cooperating with said fastening means to maintain said members in a predetermined alignment.
