- the window interrupts the guidelines of an even number of parallel corrugations of said at least one series, for example two parallel corrugations of said at least one series.
- the support foot is centered substantially in the middle of the guidelines of the two undulations.
- the support foot may be offset from the middle, so as to be closer to a corrugation than the other, for example if such a positioning makes it possible to reduce the interruption length of the corrugations taking into account the shape of the support foot.
- said at least one series of parallel corrugations is distributed equidistantly.
- the series of corrugations may have, at least locally, a less regular distribution.
- the corrugations are projecting on the side of an internal face of the sealing barrier intended to be in contact with a fluid.
- the connecting pieces comprise a plurality of end pieces disposed at a distance from the support foot so as to close interrupted ends of the two corrugations between the guidelines of which the support leg is centered. By such end pieces, one can close all the corrugations whose window interrupts the guidelines, so as to restore the continuity of the sealed barrier.
- the support foot comprises a hollow envelope of generally tabular shape whose longitudinal axis is substantially perpendicular to the vessel wall and a transverse closure wall closing the envelope in a sealed manner to achieve the continuity of the sealing barrier at the support foot.
- a hollow form may in particular be preferred to limit the effective cross section of the support foot capable of creating a thermal bridge.

- Another idea underlying the invention is to have such a support foot in a way that does not jeopardize the essential mechanical properties of the corrugated waterproofing membrane, including its sealing and resistance to thermal contraction or pressure efforts.
- Certain aspects of the invention are based on the idea of interrupting undulations of a corrugated waterproofing membrane at a passage area of a support foot, and positioning this support foot at a location which to limit the length of these interruptions, in order to limit the loss elasticity of the membrane that may result from such interruptions.
- Other aspects of the invention start from the idea of locally displacing undulations in order to bypass the zone of passage of the support foot without interrupting these undulations.

- FIG. 1 partially shows a sealed and thermally insulating tank 1 consisting of tank walls 2 and 3 attached to the inner surface of corresponding walls 4 and 5 of a supporting structure.
- the supporting structure is for example the inner hull of a double hull ship or a construction on land.
- the walls of the tank comprise at least one sealing barrier 6 and minus a thermal insulation barrier 7.
- a secondary sealing barrier not shown, between the supporting structure and the sealing barrier 6, which is said to be primary in this case.
- the tank 1 can be made according to various well-known geometries, for example a prismatic geometry in the hull of a ship or a cylindrical geometry on land or other. Moreover, many methods are available to achieve the thermal insulation and sealing barriers, for example from prefabricated elements.
- an elongate rigid member constituting a support leg 10, which extends through the thermal insulation barrier 7 and the sealing barrier 6, so that one end bears against the bottom wall 5 of the supporting structure and that the other end protrudes into the tank away from the sealing barrier 6.
- the support leg 10 can for example be used to support a device 9 in front of be immersed in the tank.
- a device 9 in front of be immersed in the tank.
- it can be disposed at the base of a pumping mast of the tank, not shown.
- the support foot is here shown on a bottom wall of the vessel, a similar rigid element can be arranged in the same way at other locations in the vessel, for example as a support or spacing element for maintaining any object remote from the tank wall.
- the sealing barrier 6 consists of a plurality of corrugated plates 11 corrugated whose inner face is intended to be in contact with the fluid.
- the sealed plates 11 are thin elements of metal such as stainless steel sheet or aluminum and are welded together at marginal overlap zones 12.
- the welds are of the overlap weld type whose method is described in detail for example in FR-A-1387955.
- the sealing plates 11 may be designed in various ways as to their shapes and dimensions, so that the weld areas may be variously positioned.
- the sealed plates 11 comprise, on their internal face, a first series of so-called longitudinal waves 15 and a second series of so-called transverse corrugations 16 whose respective directions are perpendicular.
- the first series of corrugations 15 has a height less than the second series of corrugations 16.
- the corrugations 15 are discontinuous at their crossings 18 with the corrugations 16 which are continuous.
- the longitudinal and transverse corrugations 16 project inwardly from the vessel 1.
- the support foot 10 has here a circular section of revolution, with a frustoconical lower portion 13 which connects at its smaller diameter end 17 to a cylindrical upper portion 14.
- the larger diameter base of the portion frustoconical 13 is in abutment against the wall 5 of the carrier structure.
- the frustoconical portion 13 extends through the thickness of the vessel wall beyond the level of the sealing barrier 6.
- the cylindrical portion 14 is sealingly closed by a circular plate 19, which may be for example welded to a not shown inner rim of the cylindrical portion 14.
- the corrugated waterproof plates 11 forming the sealing barrier 6 are cut so as to define a square window 25 around the support foot 10.
- a tight connection of connecting pieces is made between the support leg 10 and the sealing plates 11.
- the diameter of the support leg 10 is greater than the spacing between the corrugations of the first series 15 , some of the longitudinal corrugations indicated at 20 and whose guideline A intersects the support foot 10 have been interrupted at the window 25.
- the diameter of the support leg 10 is greater than the spacing between the of the second series 16
- some of the transverse corrugations indicated in FIG. 21 and whose guide line B intersects the support foot 10 have been interrupted ues at the window surrounding the support leg.
- the size of the window 25 is in practice greater than the diameter of the support leg 10, so that the establishment of the connecting pieces is relatively easy.
- the window 25 formed in the corrugated sheet layer could similarly interrupt corrugations whose guideline, without actually cutting the support foot, would be too close a close proximity of the support foot to allow the establishment connecting pieces between them and the support foot.
- the center C of the support foot 10 is positioned between the guidelines A for interrupted corrugations 20 and between the guidelines B of the interrupted corrugations 21, and more precisely in the middle of these guidelines in FIG. 3. It results from this positioning the guideline A or B each time cutting the support foot 10 along a rope shorter than the diameter of the support foot 10. Therefore, and given the space to exist between the edge of the window 25 and the support foot 10 to allow the establishment of the connecting pieces, this positioning of the support foot makes it possible to interrupt each of the undulations 20 and 21 for a shorter distance than in the case where the guideline A or B would cut the support foot according to its largest transverse dimension, that is to say its diameter in the case of a circular section. It is advantageous to interrupt the corrugations of the sealing barrier for as short a distance as possible, since these interruptions are capable of locally reducing the flexibility of the sealing barrier and thus of promoting locally its fatigue and wear. .
- the centering of the support foot halfway between the interrupted undulations 20 and halfway between the undulating corrugations 21 provides an optimal result.
- Other forms of section and other foot positions may also be considered.
- One principle that can be used to adapt each time the positioning of the support foot between the corrugations is to choose a position that minimizes, or at least decreases, the transverse dimension of the support foot that intersects the guideline of the interrupted undulation.
- an appropriate optimization parameter to adapt the positioning of the support foot may be the length of the longest interruption or cumulative length of interruptions obtained.
- the window 25 has a square shape which facilitates the cutting of the sealed plates 11 to the desired shape.
- other forms of windows can also be implemented, depending in particular on the geometry of the support foot.
- FIGS. 4 to 8 a detailed embodiment of the tank wall in the zone of the support foot 10 will now be described.
- This embodiment is particularly suitable for a tank whose walls have two barriers. sealing and two thermal insulation barriers. Barrier 6 will therefore be qualified as a primary sealing barrier.

- the upper block 33 is aligned with the outer sides of the lower block 31 , so as to reveal an area of the waterproof coating 32 located on an inner rim and on end flanges of the lower block 31.
- the panel 30 may be prefabricated by gluing with materials similar to those taught in the application FR-A-2781557, including polyurethane foam and plywood for insulation barriers and a composite material of aluminum foil and fiberglass for the secondary sealing barrier.

- four strips 38 of the sealed composite material of aluminum foil and fiberglass are adhered to the waterproof coating 32 of the panels 30, each time so as to overlap the flanges of end of two lower blocks 31.
- Figure 7 shows the same area of the vessel wall after placement of the primary isolation barrier. This is completed between the upper insulating blocks 33 and the support leg 10 by means of four corner blocks 40 and four medial blocks 41, the inner side of which in each case follows the rounded contour of the primary plate 24 and the 28. These blocks 40 and 41 are also shown on the left part of FIG.
- two closure plates 45 are disposed around the primary plate 24 and sealed thereto over its entire periphery.
- the plates 45 are cut in a semicircle at their inner edge 46, while their outer edge 47 defines a square of dimension slightly greater than the window 25 formed in the corrugated waterproof plates 11.
- the two closure plates 45 are superimposed at the level of areas 48 where they are welded together.
- FIG. 8 An exemplary embodiment of an end piece 50 is shown in FIG. 8.
- the end piece 50 comprises a two-part sole 51 and 52 intended to be welded in a sealed manner respectively on the closure plate 45 and on the plate 11, and a shell 54 intended to be welded sealingly to the end of the corrugation 20 or 21.
- a recess 53 between the parts 51 and 52 of the sole has an amplitude substantially equal to the thickness of the plate waterproof 11.
- the cutting of the insulating blocks and other prefabricated elements shown in Figures 2, 4, 6 and 7 to form the secondary insulation barrier, the secondary sealing barrier and the primary insulation barrier is purely illustrative. Similar elements can be cut and prefabricated in other forms so that the mounting of the vessel wall involves a higher or lower number of elementary parts.
- the four L-shaped corner panels 30 are replaced by two U-shaped panels or a single panel in the form of a square frame.
- the support foot considered above requires a window size approximately equal to twice the spacing 55 between two corrugations 15 or 16, which are here equidistant. For this, two waves of each series were interrupted.
- this arrangement of the support foot and the vessel wall in its vicinity may be adapted to other dimensions of the support foot.
- the corresponding window may interrupt a larger number of corrugations in one or each series, for example three or four or more corrugations.
- FIG. 9 elements identical or similar to those of FIG. 3 bear the same reference numeral increased by 100.
- the transverse dimension of the support foot 110 being greater, for example greater than or equal to approximately three times the spacing 155 between the corrugations 115 or 116, the window 125 formed in the corrugated metal membrane for the passage of the foot 110 interrupts in this case the guidelines of four respective undulations in each series.
- this embodiment provides for interrupting two corrugations 120, respectively 121, of each series as in the previous embodiment, while the other two corrugations 158, respectively 159 of each series are locally offset at a distance from the support foot 110 from their original guideline, but finally are not interrupted.
- the sealing barrier 106 is modified at two concentric square windows 125 and 160.
- the sealing barrier 106 consists of sealed plates 111 carrying longitudinal corrugations 115 and transverse 116 distributed equidistantly.
- the sealing barrier 106 is continued with other corrugated sealing plates, that is to say two generally C-shaped plates 161 in the present case, which carry distributed corrugations. differently, that is to say less spaced in the present case.
- the corrugations of the plates 161 constitute in particular a central segment 162, respectively 163, offset at a distance from the support leg 110, for each of the corrugations 158, respectively 159.
- the structure of the sealing barrier 106 at the level of the window 125 and inside thereof is similar to the embodiment of Figure 3.
- deflection parts 170 are used.
- the deflection piece 170 comprises a soleplate in two parts 171 and 172 intended to be welded in a sealed manner respectively on a plate 111 or 161 of the barrier. sealing 106 and on an adjacent deviating member 170, and an angled corrugation 174 whose guideline forms a chosen angle, for example 135 °.
- the bent corrugation 174 is intended to be sealingly connected to the adjacent end of the corrugation 158 or 159 and to the bent undulation of the adjacent deviation piece.
- a recess 173 between the parts 171 and 172 of the soleplate has an amplitude substantially equal to the thickness of the sheet used to make the sealing plates 111 or 161 or the deflecting parts 170.
- a sheet of the same thickness is used for these different pieces.
- all the corrugations whose window interrupts the guideline for example two corrugations of each series as in Figure 3, are extended through the window according to a staggered path, similarly to the corrugations 158 and 159 of FIG. 9.
- the flexibility of the membrane can be improved since no ripple is finally interrupted by an end piece at the foot of FIG. support.
- the primary sealing barrier is made of sheet metal having two sets of mutually perpendicular corrugations.
- other types of corrugated metal membranes with less or more corrugations and / or a different arrangement of the corrugations can be similarly employed.
