FLUIDTIGHT AND THERMALLY INSULATING TANK

摘要

A fluidtight and thermally insulating tank wall comprises:;a multi-layer structure comprising a fluidtight barrier (5) and a thermally insulating barrier (4), retaining rods (22) attached to the bearing wall (7) between the insulating elements and extending in the direction of the thickness of the multi-layer structure to hold the multi-layer structure on the bearing wall, in which crossmembers (30) are attached to the retaining rods (22) such that in each instance a crossmember extends between two retaining rods at the interface between two insulating elements, the cover panels (11) of the insulating elements being connected to the crossmembers (30) so as to be held against the bearing wall via the crossmembers, and the fluidtight barrier (5) being connected to the crossmembers (30) so as to be held against the cover panels of the insulating elements via the crossmembers.

1. Fluidtight and thermally insulating tank built into a bearing structure (1) to contain a fluid, in which one wall of the tank comprises:
a bearing wall (2, 3) of the bearing structure,
a multi layer structure comprising a fluidtight barrier (5, 105, 205) and a thermally insulating barrier (4, 104) which is arranged between the fluidtight barrier and the bearing wall, the thermally insulating barrier comprising juxtaposed insulating elements (10, 110, 210), an insulating element including:thermally insulating lagging material arranged in the form of a layer parallel to the bearing wall,bearing elements (12, 112, 212) which rise up through the thickness of the thermally insulating lagging material to react compressive loads, anda cover panel (11, 111, 211) placed on the bearing elements and having a support surface (16) parallel to the bearing wall for supporting the fluidtight barrier, and retaining rods (22, 122, 222) attached to the bearing wall between the insulating elements and extending in the direction of the thickness of the multi layer structure to hold the multi layer structure on the bearing wall,in which crossmembers (30, 130, 230) are attached to the retaining rods (22, 122, 222) such that in each instance a crossmember extends between two retaining rods at the interface between two insulating elements, characterized in that:
an anchor plate (33, 133) is arranged in line with the interface between two insulating elements, connected with the crossmember (30, 130) so as to lie flush with the cover panel (11, 111) of an adjacent insulating element, the anchor plate having a lower surface which bears against an edge of the cover panel and an upper surface on which the fluidtight barrier (5, 105) is placed, so that:the cover panel (11, 111, 211) that covers the insulating elements is connected to the crossmember (30, 130, 230) by the anchor plate so as to be held against the bearing wall via the crossmember, andthe fluidtight barrier (5, 105, 205) is connected to the crossmember (30, 130, 230) by the anchor plate so as to be held against the cover panels that cover the insulating element via the crossmember.
