Abstract:
The invention relates to a sealed and thermally insulated tank for storing a fluid comprising a thermal insulation barrier and a sealing membrane supported by the thermal insulation barrier, the thermal insulation barrier comprising a plurality of juxtaposed parallelepidal insulating blocks (3, 7) each one comprising: - a bottom panel (10) and a cover panel (11), which are spaced apart in a thickness direction of the insulating block (3, 7); - a plurality of pillars (13) interposed between said bottom (10) and cover (11) panels and extending in a thickness direction; and - a lagging lining placed between the pillars (13); said plurality of insulating blocks (3, 7) comprising at least one reinforced insulating block (3, 7) equipped with at least one anti-overspill reinforcing structure (14) extending longitudinally along a reinforced lateral face of said reinforced insulating block (3, 7), between the bottom panel (10) and the cover panel (11).
Abstract:
The invention relates to a tight and insulating tank (2) incorporated into a support structure (1) comprising a double tight membrane intercalated with a double insulating barrier, the tank further comprising, for at least one longitudinal partition of the support structure, a flat primary anchor (21 A) attached on the transverse partition of the support structure, a primary metal frame (23A) extending in the plane of the longitudinal primary tight membrane (9A) between the anchoring plane and said tight membrane, a primary composite beam (41A) developing parallel to a transverse partition of the support structure and resting on the primary metal frame, a proximal end (38A) of a primary coupler (37A) anchored on a longitudinal partition of the support structure comprising a maintaining element (49A) bearing on a primary metal reinforcing plate (44A) of the primary composite beam, a transverse tight membrane of the tank being attached on the primary metal reinforcing plate.
Abstract:
The invention relates to a method for manufacturing a freestanding body intended for thermal insulation of a vessel, with moisture barrier, for storing a fluid, said method comprising: providing a plurality of supporting webs (14) made of a composite material comprising a thermoplastic matrix reinforced by fibres; providing a bottom panel (10) and a cover panel (11); inserting the supporting webs (14) between the bottom panel (10) and the cover panel (11), such that the bottom panel (10) and the cover panel (11) are separated in the thickness direction of the body and that the supporting webs (14) extend vertically in the thickness direction; attaching the supporting webs (14) to the bottom panel (10) and to the cover panel (11); filling a plurality of compartments (15) arranged between the supporting webs (14) with a heat-insulating filler; wherein the bottom panel (10) and the cover panel (11) each comprise at least one thermoplastic element (21, 22) for attaching the supporting webs (14); and wherein the supporting webs (14) are attached to the bottom panel and to the cover panel by a thermoplastic welding operation performed at the interface areas (25) between the supporting webs (14) and the thermoplastic elements (21, 22) of the bottom panel (10) and the cover panel (11). The invention also relates to a body manufactured thereby, and to a sealed, thermally insulating vessel comprising a thermal-insulation barrier including a plurality of bodies such as mentioned above.
