Claim 12:
13. The fluid-tight and thermally insulating tank wall according to claim 12, wherein the wave reinforcements arranged under the corrugations of the first series of parallel corrugations are first wave reinforcements, the tank wall further including second wave reinforcements arranged under corrugations of the second series of parallel corrugations, two second wave reinforcements being disposed in the corrugation of the second series of parallel corrugations forming the node on either side of said node,
wherein the second wave reinforcements are hollow, the connecting member including a central portion inserted between the soles of the first wave reinforcements, the connecting member further including two lugs, each of said two lugs projecting from the central portion of the connecting member in a longitudinal direction of the second series of parallel corrugations and penetrating into a respective second wave reinforcement,
wherein the two lugs are nested in the second wave reinforcements in such a manner as to assemble said two second wave reinforcements to the connecting member,
wherein the connecting member includes a plane part having the shape of a cross, said lugs and said ends of the connecting member forming four branches of the cross, and
wherein a plurality of rows of wave reinforcements are arranged in the respective corrugations of the first series of parallel corrugations over substantially all the length of the rectangular sheet metal part and rows of second wave reinforcements are arranged in the corrugations of the second series of parallel corrugations, the second wave reinforcements being assembled to the first wave reinforcements by cooperation with the connecting members at the level of the nodes to form a framework of the corrugated rectangular sheet metal part.
