Abstract:
A sealed and thermally insulating wall for a tank for storing fluid includes a heat-insulating panel and a sealing plate. The inner face of the heat-insulating panel has a stress-relieving slot.
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:
Sealed and thermally insulating tank incorporated into a polyhedral bearing structure, a first bearing wall and a second bearing wall forming an edge corner, the tank having a first tank wall, a thermally insulating barrier and a sealed membrane, the tank further has an angle bracket with a first flange and a second flange in such a way that the angle bracket connects in a sealed manner. The sealed membrane of the first tank wall and the sealed membrane of the second tank wall in line with the edge corner, in which the angle bracket has a pair of first tabs and a pair of second tabs, the tank has a pair of first anchor rods coupled to a respective first tab and a pair of second anchor rods coupled to a respective second tab in such a way as to transmit a tensile load between the angle bracket.
Abstract:
Corrugated fluid-tight membrane fluid-tight wall (1) including two series of parallel corrugations forming a plurality of nodes (5) at the crossings of said series of corrugations, wave reinforcements (11) being arranged under the corrugations (3) of the first series of corrugations (3), two successive wave reinforcements (11) in a corrugation (3) each including a hollow sole (15) and a reinforcement portion (16) disposed above the sole (15), the two wave reinforcements (11) being developed in the corrugation (3) on either side of a node (5), a connecting member (13) at the level of the node (5) being nested in the soles (15) of said two wave reinforcements (11) in such a manner as to assemble the two wave reinforcements (11) in an aligned position.
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.
