SELF-SUPPORTING FRAME SUITABLE FOR SUPPORTING AND THERMAL INSULATION OF THE SEALED MEMBRANE Russian patent published in 2023 - IPC F17C3/06 F17C13/08 B63B25/16 

FIELD: fasteners.

SUBSTANCE: group of inventions relates to a self-supporting frame. The frame comprises one groove (30) formed in the cover panel and extending to the top surface of the cover panel to receive a support for welding. At least one bearing partition (26) extends longitudinally and is located vertically in line with the groove (30). Fasteners (35) installed at right angles in the bottom plate (22) and the upper surface of the carrier partition (26) secure the carrier partition to the cover panel. The upper surface of the bearing partition (26) is wider than the lower part (32) of the slot (30), and the fasteners (35) are installed in the area of the lower plate (22), which is offset in the lateral direction relative to the lower part (32) of the slot. The main insulating barrier of the tank essentially consists of frames filled with thermal insulation pad. The main sealed membrane is held on the cover panels by means of supports for welding connection inserted into the grooves (30).

EFFECT: strengthening of the self-supporting frame, which can be used for the manufacture of the main insulating barrier in the tank.
