WALL OF A HEAT-INSULATING AND HERMETIC TANK Russian patent published in 2023 - IPC F17C3/04 F17C13/08 B63B25/16 

FIELD: thermal insulation.

SUBSTANCE: group of inventions relates to the wall of a hermetic and heat-insulating tank. The wall contains a sealing membrane containing a corrugated metal plate, a heat-insulating barrier (5) containing a groove (27) extended in the longitudinal direction, one support (26) for welding connection supported by a heat-insulating barrier. The support (26) for welding connection contains the lower part (28) held in the groove (27), the upper part (30) located on the heat-insulating barrier, the intermediate part (29) of the support (26) for welding connection connecting the lower part (28) with the upper part (30). One support (26) for welding connection is installed in the mentioned groove (27) with the possibility of sliding in the longitudinal direction, and a corrugated metal plate is welded to the upper part (30) of the support (26) for welding connection. The upper part (30) of the support (26) for welding connection is located in the recess (32) adjacent to the groove (27). The recess (32) is formed in the heat-insulating barrier, so that the upper part (30) of the support (26) for welding is located between the sealing membrane and the heat-insulating barrier and extends the support surface (31).

EFFECT: improvement in the sliding fastening of the sealing membrane to the heat-insulating barrier while maintaining sufficient mechanical strength to withstand the loads exerted by the sealing membrane on the fastening.
