Abstract

1,245,334. Liquefied gas storage containers. TECHNIGAZ, and G. FOURNIER. 11 July, 1969 [31 Dec., 1968], No. 35154/69. Heading F4P. [Also in Division B3] A dihedrally shaped metal sheet suitable for connecting adjacent walls of a liquefied gas storage container having convex dihedral corrugations 2, 2<SP>1</SP> of uniform cross-section projecting on the internal side of each face of the dihedral angle and extending in a longitudinal direction at right angles to the crest of the dihedron, is characterized in that the concave fold lines at the base of each corrugation extend to the crest of the dihedron, where they meet the homologous lines of the other corrugation and each corrugation crest line divides at its end into two diverging lateral convex fold lines AB<SP>1</SP>, A<SP>1</SP>B<SP>1</SP> or AB, A<SP>1</SP>B joining respectively the crest of the dihedron at the corresponding parts of concurrence of the concave fold base lines, on either side of the corrugations, and into a central concave-fold line B<SP>1</SP>C<SP>1</SP> or BC which divides at its re-entrant end into two diverging lateral concave fold lines AC<SP>1</SP>, A<SP>1</SP>C<SP>1</SP> or AC or A<SP>1</SP>C joining respectively the points of concurrence and into a medial convex fold line CC<SP>1</SP> interconnecting the respective re-entrant ends of the two mutually confronting corrugations, so as to define adjacent triangular facets forming a common skew polyhedral surface of connection and transition between the two corrugations. The interconnecting crest portion CC<SP>1</SP> has a depression 4a at its crest which is dihedral and extends transversely of the crest and over at least part of the height of the portion.
