Thermally insulating, fluid-tight composite wall, prefabricated elements for constructing the same and method of constructing said wall
First Claim
1. A thermally insulating, fluid-tight composite wall, which comprises successively, from the exterior to the interior, a self-supporting external wall;
- an initially deformable and subsequently hardenable packing material which is placed on said self-supporting external wall in deformable state and is thereafter hardened;
a bed of thermally insulating elements placed on said packing material while the latter is still in deformable state so that the entire space between said self-supporting wall and said thermally insulating elements is filled by said packing material, and said bed is at least partially fastened to said self-supporting wall after hardening of said packing material, said thermally insulating elements defining between themselves joints wherein joining members are located and which join said thermally insulating elements; and
a fluid-tight internal lining, forming a primary barrier, of a flexible laminated material offering mechanical strength and cold resistence.

Abstract
The invention relates to a thermally insulating composite wall for any kind of tank on ships or on land. The wall comprises a self-supporting external wall, a bed of thermally insulating elements secured to said wall at least partially by means of a hardened packing material and a fluid-tight internal lining; said material may notably be a cellular material in contact with all the external surface of this bed and obtained by in situ expansion and subsequent hardening of a deformable product capable of spontaneous expansion which has been previously placed according to a discontinuous distribution.
