Abstract:
A sealed and thermally insulated tank for storage of a fluid, having a plurality of multilayer walls. A first of the walls has a secondary thermally insulating barrier including a first insulating panel along the intersection between the load-bearing structure of first wall and the load-bearing structure of an adjacent second wall. A second insulating panel is juxtaposed with the first insulating panel along one edge of the first panel opposing the second wall. The first wall has a secondary sealing membrane including a first corrugated metal sheet welded to a small metal plate of the first insulating panel; and a second corrugated metal sheet welded to the small metal plate of the second insulating panel. The first metal sheet and the second metal sheet are welded together via a joggled edge permitting the first and the second metal sheets to be lap welded to one another.
Abstract:
A sealed and thermally insulating tank intended for the storage of a fluid, the tank having a secondary insulating barrier having juxtaposed insulating panels; and a primary insulating barrier having insulating panels that are each arranged straddling at least four secondary insulating panels and anchored to the latter. The sealed tank is equipped with a through-element passing through a specific zone of the wall. In the specific zone of the wall, the longitudinal directions of the primary panels are perpendicular to the longitudinal directions of the secondary insulating panels. The through-element passes successively through an opening made in one of the secondary insulating panels and an opening made in one of the primary insulating panels.

Abstract:
A sealed insulating tank in which the secondary insulating barrier, the secondary sealing membrane, and the primary insulating barrier essentially consist of a set of prefabricated panels juxtaposed on the supporting structure. Sealing strips are arranged so that they overlap the adjoining edge zones of the leaktight linings of the prefabricated panels in order to complete the secondary sealing membrane between the prefabricated panels. Insulating blocks arranged on the sealing strips have a layer of thermal insulation covered by a rigid board and a reinforcing mat having a stiffness under tension which is greater than or equal to the stiffness under tension of the sealing strips and is glued to the layer of thermal insulation on a face of the layer of thermal insulation opposite the rigid board, the insulating block being each time fixed to the prefabricated panels by gluing the reinforcing mat to the underlying sealing strip.
Abstract:
A method for producing a sealed and thermally insulating wall for a fluid storage tank includes attaching plural anchoring elements to a support structure; installing modular formwork elements on the support structure, the modular formwork elements having a shape that protrudes relative to the support structure and that defines, with the support structure and the plurality of anchoring parts, compartments having an open side opposite the support structure; spraying insulating foam into the compartments through the open side to form plural insulating sectors made from sprayed insulating foam; arranging insulating junction elements in a stressed position in which they are stressed between the insulating sectors and capable of expanding when the insulating sectors contract, to ensure continuity of the thermal insulation; and attaching a sealing membrane to the anchoring elements.

Abstract:
An impermeable and thermally insulated tank built into a load-bearing structure, the tank wall comprising: a thermally insulated barrier attached to a load-bearing wall and made of insulated blocks, juxtaposed in parallel rows separated from one another by gaps, an impermeable barrier supported by the thermally insulated barrier and made of welded metal sheets. Each insulated block carries, on the face of same opposite the load-bearing wall, two metal connecting strips arranged in parallel to the sides of the insulated block. The sheets of the membrane carried by the insulated block are welded to the strips. The connecting strips are rigidly connected to the insulated block carrying same. The sheets each have at least two orthogonal folds parallel to the sides of the insulated blocks, the folds being inserted into the gaps formed between two insulated blocks.
