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:
The invention relates to a sealed and thermally insulating tank wherein the distance between two adjacent corrugations of the corrugated metal sheets of the sealing membrane is equal to a predetermined corrugation interval io, the sealing membrane comprising, around a through-element:two notched rectangular metal plates 3io wide in the first direction and 7io long in the second direction, which are symmetrical to one another, each notched rectangular metal plate having three outer edges disposed in line with a plurality of anchor plates and welded onto the first plurality of anchor plates and an inner edge having a notch formed to avoid cutting a square window through which the through-element passes, and two metal retrofit plates disposed between the non-notched portions of the inner edges of the two notched rectangular metal plates.
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 insulating 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 insulating block carries, on the face of same opposite the load-bearing wall, two metal connecting strips arranged in parallel to the sides of the insulating block. The sheets of the membrane carried by the insulating block are welded to the strips. The connecting strips are rigidly connected to the insulating block carrying same. The sheets each have at least two orthogonal folds parallel to the sides of the insulating blocks, the folds being inserted into the gaps formed between two insulating blocks.

Abstract:
A sealed and thermally insulating tank whose wall is fixed to a carrier wall. The tank wall includes a secondary thermal insulation barrier which is retained on the carrier wall and a secondary sealing barrier which is supported by the thermal insulation barrier. There is also a primary insulation barrier which is fixed to the secondary element of the tank by a fastener which is connected to the secondary insulation barrier.
Abstract:
A sealed and thermally insulating tank for storing fluid has a wall including a supporting structure, a primary thermal insulation barrier and a primary sealing membrane lying against the primary thermal insulation barrier, contacting the stored fluid. The primary thermal insulation barrier includes a primary insulating panel which includes a bearing zone collaborating with an anchoring device bearing against the bearing zone of the external rigid plate holding it toward the supporting structure. The primary thermal insulation barrier includes a reinforcing insulating plug extending, in the thickness direction, from the bearing zone of the external rigid plate to a specific zone of the primary sealing membrane to take up the compressive forces on the specific zone of the primary sealing membrane. The reinforcing insulating plug includes a polymer foam layer having a compressive yield strength greater than that of the polymer foam layer of the primary insulating panel.
Abstract:
A sealed and thermally insulating tank having a sealing membrane, a thermal insulation barrier, and a reinforcing piece for reinforcing the sealing membrane against the pressure of the fluid contained in the tank. The thermal insulation barrier has a groove parallel to the longitudinal direction of the corrugation, and the reinforcing piece has a retaining rib engaged in the groove, the retaining rib forming a lug extending in the groove beyond a longitudinal end of the main body in the longitudinal direction of the corrugation. A stop element attached to the thermal insulation barrier stops the reinforcing piece in the longitudinal direction of the corrugation in a first direction and cooperates with the lug to stop the reinforcing piece in a direction moving away from the support surface.
