INSULATING ELEMENT FOR A SEALED AND THERMALLY INSULATING TANK WALL

摘要

In a sealed and insulating tank wall, a retaining member (31-35) collaborates with edge pieces (21) of the four insulating elements (13) of the insulating barrier in order to hold the four insulating elements directly or indirectly against the bearing structure. Cutouts at the adjacent corners of the four insulating elements delimit an opening (50) through the cover panels (14) to provide access to the retaining member. A closure plate (52) is positioned in the opening in line with the retaining member (31-35) to complete the substantially continuous planar bearing surface of the sealed membrane. Each cutout at the corner of a cover panel is bordered by a flat rim (51) formed in the thickness of the cover panel (14) and parallel to the upper surface of the cover panel. The closure plate (52) rests on the flat rims (51).
