SEALED AND HEAT-INSULATING TANK Russian patent published in 2024 - IPC F17C3/02 F17C3/04 F17C13/00 B63B25/10 

FIELD: machine building.

SUBSTANCE: group of inventions relates to a sealed and heat-insulating reservoir. Reservoir comprises a first reservoir wall and a second reservoir wall, each of said first reservoir wall and second reservoir wall is supported by a bearing structure and comprises auxiliary heat-insulating barrier (2), auxiliary sealing membrane (3), main heat-insulating barrier (4) and main sealing membrane (5). Reservoir comprises two angular structures (1) located in angular area and separated from each other by interpanel gap (8), each angular structure (1) contains auxiliary angular unit (6) and each angular structure (1) has a plurality of main angular assemblies (12) attached to said auxiliary angular assembly (6). Reservoir comprises main angular connection unit (13) attached to two auxiliary angular units (6) of two angular structures (1), which are located next to each other so as to be located above said inter-panel gap, and said main angular connection unit (13) exhibits bending behaviour different from that of main angular units (12) of angular structures (1).

EFFECT: increased strength of the reservoir.
