- the slot 58 whose two ends 58a and 58b are indicated in the sectional view of FIG. 4, is long enough to allow the support bar 50 to be completely retracted into the space 38 between the two insulating blocks.
- this retracted position shown in FIG. 6
- the deployment movement of the support bar 50 is shown schematically by the arrow 98 in FIG. 6.
- the length of the planar primary insulating panel 29 is nine times the width of the primary corner structure 30, so that four support bars spaced apart by an interval of three times the width of the the primary corner structure 30 engages the plane primary insulating board 29 along its edge turned towards the edge, namely two support bars 50 at both ends of this edge, i.e. at two corners of the plane primary insulating panel 29, and two support bars in a central zone of the edge of the primary plane insulating panel 29.
- This central zone is shown in FIG.
- the plane primary insulating panel 29 has the general shape of a rectangular parallelepiped with a longitudinal edge 26 parallel to the edge 10.
- the flat primary insulating panel 29 has, for example, a composite structure consisting of a layer of insulating polymer foam sandwiched between a rigid bottom plate, an exposed area 28 of which is apparent, and a rigid cover plate 25.
- the rigid cover plate 25 and the insulating polymeric foam layer are hollowed out with a groove 27 extending perpendicular to the edge 10 to the right of the plate 20 and opening on the longitudinal edge 26 to discover the uncovered area 28 of the rigid bottom plate.
- the second portion 51 of the support bar 50 is engaged in the groove 27 and bears on the uncovered area 28 of the rigid bottom plate, possibly via a shim thick 48.
- Another shim 49 may be interposed between the other end of the support bar 50 and the secondary membrane (not shown).
- the shims 48 and 49 are dimensioned to ensure the parallelism between the support bar 50 and the bottom plate of the primary plane insulating panel 29. They are made of a sufficiently soft material to avoid the risk of punching, marking or For example, they may be made of plywood, plastic or epoxy resin.
- the support bar 50 mounted in this way has several advantages: the second portion 51 is a length cantilever substantially parallel to the flat wall of the vessel which bears on the primary insulating panel plane 29, preferably to distance from the edge of this panel. It thus makes it possible to retain the plane primary insulating panel 29 on the secondary membrane without requiring complex arrangements on the primary insulating panel plane 29: it suffices to disengage a flat portion of the bottom plate.
- the length of the second portion 51 is easily adjustable by sliding the stud 45 in the length of the slot 58.
- This arrangement is therefore easily adapted to planar insulating panels having different dimensions or grooves 27 having different lengths.
- the length of the groove 27 can in particular be shortened following cutting of the edge 26 to reduce the width of the insulating panel 29.
- the support bar 50 is anchored to a stud carried by the secondary angle structure 13, its position is not sensitive to the dimensioning of the secondary planar insulating panels (not shown) adjacent to the structure of the secondary structure.

- all the projecting edges 53 of all the angles 32 may have this cutout 54 to standardize the manufacturing.
- the cutouts 54 serve to provide sufficient space between the two projecting flanges 53 for the passage of a clamping tool 60, for example a pipe wrench having a cylindrical head 61 or a screwdriver.
- the depth of the cutout 54 in the direction of the edge 10 can therefore be dimensioned to provide a distance D slightly greater than the diameter of the cylindrical head 61 between the bottoms of the two cutouts 54 vis-à-vis.
- the length of the cutout 54 along the end edge 55 may be substantially equal to the same distance D, for example about 30mm.
- the insulating joint 39 has at its base a pin inserted into the hollow section U-shaped the support bar 50.
- the insulating joint 39 also has a cylindrical well 56 in line with the blind nut 42 to receive the stud 45 and the nut 47.

- the metal angle 232 also has orifices 237.
- the metal angle 65 does not have orifices and can be continuous, since the portion of the dihedral insulating block 231 facing the last primary angle structure 130 spans the gap 66 between the penultimate structure of the secondary angle 13 and the last secondary angle structure 1 13 and extends on the last secondary angle structure 1 13 without being fixed thereto.
- This arrangement has the advantage of being independent of the precise size of the gap 66 in the secondary insulation barrier, which can be easily adjusted to compensate for manufacturing tolerances.
