Embodiment Construction

[0131] exist figure 1 , the walls of the sealed and thermally insulated container are shown. The general structure of such containers is well known and has a polyhedral shape. Therefore, the emphasis will be on describing only one wall region of the container, it being understood that all planar walls of the container may have a similar general structure.

[0132] Therefore, irrespective of the effective orientation of the container wall in the Earth's gravitational field, the terms "on" and "on" shall be used to denote a position located in the thickness direction of the container wall towards the interior of the container, And the terms "under" and "beneath" are used to denote a position located towards the exterior of the container, that is to say towards the support structure.

[0133] The walls of the container, from the outside to the inside of the container, comprise a support wall 1 , a secondary thermal insulation barrier 2 formed by secondary insulating blocks 3 ju...

Abstract

The invention relates to a parallelepiped insulating block (307) including a rectangular bottom plate (326) and a rectangular cover plate parallel to the bottom plate and spaced apart from the bottomplate in the direction of the thickness of the insulating block by supporting pillars (324, 325, 274), in which the cover plate of an insulating block includes a network of beams attached to the upperends of the supporting pillars, each beam resting on a plurality of said supporting pillars in order to distribute the pressure forces on said supporting pillars, and a continuous covering web (278)arranged on the network of beams which is less thick than the beams, the network of beams including an edge beam (280) arranged along one edge of the insulating block and resting on the two main supporting pillars (274) arranged at the ends of said edge.

Description

technical field [0001] The present invention relates to the field of sealed and thermally insulated film containers for storing and / or transporting fluids, such as cryogenic fluids. [0002] Sealed and thermally insulated membrane containers are used in particular for the storage of liquefied natural gas (LNG), which is stored at approximately -162°C at atmospheric pressure. These containers can be installed on land or on floating structures. Background technique [0003] In containers used to store liquefied gases at low temperatures, in the case of ship containers, the essential function of the container walls is to insulate the cargo to limit the heat flow that causes the cargo to evaporate, and also to protect the hull from cryogenic temperatures. However, the container walls must also withstand the hydrodynamic loads of the cargo, which therefore means resisting compression. [0004] One possible option for providing these functions is to produce a container wall with...
