- a corrugated metal plate 1 has on its inner face 2, a first series of so-called low parallel corrugations 5 and a second series of so-called high parallel corrugations 6, the respective directions are perpendicular.
- the terms "high” and “low” here have a relative meaning and mean that the first series of corrugations 5 has a height less than the second series of corrugations 6.
- the low undulation 5 is discontinuous, that is to say that it is interrupted by a fold 4 which extends the crown edge 7 of the high corrugation 6 protruding above the vertex edge 8 of the low corrugation 5. This form is best seen in Figure 5.
- the crown edge 7 of the high corrugation 6 comprises a pair of concave corrugations 9 whose concavity is turned towards the internal face and which are arranged on either side of the vertex edge 8 of the low corrugation 5.

- the plate 1 is made of stainless steel sheet or aluminum and has a thickness of about 1.2 mm and can be shaped by stamping. Other metals or alloys and other thicknesses are possible, knowing that a thickening of the plate 1 causes an increase in its cost and generally increases the rigidity of the corrugations. In the case of application of sealed membranes for cold liquid, a certain flexibility of the plate 1 is required to allow its thermal contraction without risk of rupture of the seal.
- the corrugated metal plate 1 is well adapted to form a tight membrane of a tank of large capacity, for example for a cold liquid product.
- the hydrostatic pressure exerted by the product contained in the tank can cause large plastic deformations of the corrugations and in particular crushing of the lateral faces of the high corrugations 6 at a distance from the crossings 3.
- the wave movements of the liquid gas against the side walls of the tank during transport may further cause dynamic pressure surges such that the corrugations also undergo significant plastic deformations.
- deformations can lead to degradation of the mechanical strength of the plates, which are subjected to significant thermal contractions, for example when they receive liquid methane, and thus adversely affect the sealing of the plates, especially in the weld zones. at the junction between the different plates of the waterproof wall. Reinforcement pieces are described below intended to avoid or limit such plastic deformations.
- a reinforcing member 15 adapted to be inserted into a high corrugation 6 on the side of the outer face of the plate 1 is shown.
- the reinforcing piece 15 has a profiled geometry with a constant cross section, which makes it possible to easily obtain a piece of the desired length by cutting a profiled body of great length.
- Such a profiled body can in particular be manufactured by extrusion.
- the part 15 has a thin semi-elliptical dome shaped upper wall 16 substantially adapted to the shape of the high corrugation 6 and intended to be turned towards the plate 1. If the reinforcing piece 15 is made of a material having a different thermal behavior of the plate 1, its dimensioning must take into account this difference to effectively withstand the wall of the corrugation at the temperature of use, for example -162 ° C for LNG.
- the bottom wall 17 of the part 15 intended to be turned away from the plate 1 has a generally flat shape to be able to bear on a support surface, formed for example by the inner surface of a thermal insulation barrier in the case of a tank for LNG
- a groove 18 of rectangular section is hollowed longitudinally in the bottom wall 17 in the middle.
- the part 15 is hollow and comprises only thin support ribs, namely two oblique ribs 19 intersecting at a core 22 and each extending between a connecting angle 20 of the walls 16 and 17 and a point located substantially at half the height of the opposite portion of the wall 16, and a short rib 21 connecting the core 22 to the bottom of the groove 18.
- a reinforcing member 115 adapted to be inserted into a low corrugation 5 on the side of the outer face of the plate 1 is shown.
- the elements similar or identical to those of the reinforcing piece 15 have the same reference number increased by 100.
- the reinforcing piece 115 differs from the part 15 essentially by the absence of flat bottom wall. The piece 115 is thus open between the two angles 120 and the groove 118 is formed under the core 122 by two parallel longitudinal ribs 121 which extend on either side of the median plane of symmetry of the piece parallel thereto. .
- a cruciform anchor 30 can be used to fix reinforcing pieces 15 and 115 in the corrugations 6 and 5 of the plate 1.
- the anchoring piece 30 comprises a central body 31 shaped of hollow cylindrical section with a generally rectangular section, the four outer faces of which respectively bear four arms extending substantially perpendicular to the axis of the body 31 and each capable of cooperating with a reinforcing piece to retain or contribute to retaining the reinforcement piece in a corresponding corrugation of the plate 1, as will be explained below.
- Two rods 32 are connected to the two short sides 37 of the body 31 and extend from the upper face of the body 31 forming a slight angle inclined towards the axis of the body so as to be closer to one another without joining.
- the rods 32 have a beveled shape towards their end remote from the body 31.
- the ends of the rods 32 are connected by a rod 33 extending perpendicularly to the axis of the body 31 and having a wider section than the end of the rods 32, for example substantially equal to the width of the rods 32 at their base.
- the rod 33 forms a fixing head capable of being wedged elastically in the undercut of the fold 4 at a cross 3 of the plate 1, described above.
- the rod 33 is dimensioned with a slightly wider section than the narrowest part of the fold 4.
- the anchor 30 may be made by molding a plastic resin.
- FIG. 5 shows the anchoring piece 30 thus attached to the plate 1.
- the anchoring piece 30 is first arranged so that the rod 33 is applied against the inlet portion 11 of the fold 4, the rods 32 perpendicular to the plate 1 and the arms of the anchor 30 respectively arranged to the right of the four segments of corrugation that meet at the crossing 3. Then a force is applied on the anchor 30 perpendicularly towards the plate 1, for example manually, so that the rod 33 resiliently crosses the inlet portion 11 and the narrow portion of the fold 4 to be housed in the bottom portion 12 where it is retained firmly by return In the attached state, the axis of the body 31 is substantially perpendicular to the mean plane of the plate 1.
- the rod 33 has a recessed section in the middle by a slot 38 extending longitudinally between the two ends of the rod 33 where the rods 32 are connected.
- the shape of the slot 38 may be a rhombus or other elongate shape.
- the slot 38 facilitates the elastic crushing of the rod 33 during its insertion in the narrow part
- the two inclined faces 34 located on the sides of the rod 33 which slide against the inner surface of the fold 4 during this insertion movement also facilitate elastic crushing.
- the rod 33 is able to deform elastically to adapt to the precise shape of the inside of the fold 4, which may slightly vary from a cross 3 to another of the same plate 1 due to tolerances
- the same anchoring piece 30 is adapted to be used in all crossings 3 of a corrugated plate of the type of the plate 1 and even in different plates of this type having a slight dispersion. in their manufacturing ribs.
- two longer arms 40 are connected to the short sides 37 of the body 31 and two shorter arms 140 are connected to the long sides 36 of the body 31.
- the arms 40 engage in both segments of the body. high ripple 6 adjacent crossing 3 where the anchor 30 is attached.
- the arms 140 engage in both segments of the corresponding low ripple.
- An arm 40 has a generally rectangular section and a general direction slightly inclined relative to the plane perpendicular to the axis of the body 31, that is to say inclined relative to the mean plane of the plate 1 in the attached state, this inclination being in a direction opposite to the rods 32.
- the arm 40 ends with a positioning plate 41 substantially parallel to the axis of the body 31, this plate 41 taking a position perpendicular to the axis of the high corrugation 6 in the attached state of the part 30, as visible in FIG.
- the width and shape of the lateral sides 42 of the plate 41 are substantially adapted to the inner section of the high corrugation 6, with a slight clearance, so that the lateral sides 42 can cooperate with the inner surface of the high corrugation 6. to stabilize the plate 41 in its position perpendicular to the axis of the high corrugation 6 in the attached state of the piece 30.
- the shape of the plateau 41 gradually widening downwards makes it possible to slide one or each lateral side 42 against the leaves 13 at the base of the high corrugation 6 during the installation of the anchoring piece 30, in order to easily guide the arm 40 to a substantially centered position within the high corrugation 6.
- a retaining tab 44 is connected to the front surface 43 of the plate 41, at a position centered laterally relative to the plate 41 and adjacent to the lower edge 45 of the plate 41, that is to say to the right of the connection point of the arm 40 with the plate 41.
- the tab 44 extends perpendicularly to the axis of the body 31, that is to say parallel to the axis of the high corrugation 6 in the attached state of the
- the tab 44 has a generally rectangular section of width slightly smaller than the groove 18 to slide in, except at a thickening forming a cylindrical pin 46.
- the portion 48 of the tab 44 situated beyond the pin 46 can engage in a sliding manner. in the entrance of the groove 18 of a reinforcing piece 15 to stop the piece 15 in the direction perpendicular to the plate 1.
- the leg portion 48 may be slightly tapered to facilitate this engagement.
- the reinforcing piece 15 is able to swing relative to the tab 44 if the second end of the reinforcing piece 15 is not retained.
- This mode of cooperation therefore presupposes the use of an anchor piece 30 or similar means at each end of the piece 15, as can be seen in FIG. 6 where a second anchor piece 130 is sketched.
- a first anchor piece 30 is installed at a first intersection. Then a reinforcing piece 15 is installed between this crossing and the second crossing, by engaging the leg portion 48 of the first anchor piece in one end of the groove 18. Then a second anchor piece 130 is installed at the second crossing by engaging the leg portion 48 of the second anchor in the other end of the groove 18.
- two identical anchoring parts 30 and 130 are attached respectively in the two crossings 3, so that each has an arm 40 which extends in a respective end portion of segment 14, in opposite directions.
- the reinforcing piece 15 of length less than or equal to the distance separating the two lugs 46 from the two arms 40 facing each other is thus retained in the segment 14 in the position shown in FIG. 6.
- the two ends of the reinforcement piece 15 are supported respectively by the leg portions 48 of the two anchoring pieces 30 and 130, so that the reinforcing piece 15 is retained at the plate 1 in the direction perpendicular to the plate 1 and can not rock .
- the lugs 46 provide in each direction a stop capable of cooperating with the end surface 49 of the reinforcing piece 15 at the entrance of the groove 18 to stop the reinforcing piece 15 in the longitudinal direction of the high corrugation 6.
- an arm 40 offers another possible mode of cooperation with a reinforcement piece 15.
- the reinforcing piece 15 is forcibly engaged on the tab 44 until to elastically wedge the lug 46 in the groove 18, which is narrower than this.
- it can be made with an inner recess 50, for example of cylindrical shape, as shown in Figure 7.
- the reinforcing piece 15 is pushed to put the longitudinal end surface 49 bears against the front surface 43 of the plate 41, which makes it possible to accurately position the reinforcing piece 15 with respect to the anchoring piece 30, and thus with respect to the plate 1.
- the reinforcing piece 15 is firmly retained on the plate 1 by the sole effect of the anchoring piece 30.
- the method of attachment can be used to retain a reinforcing piece 15 in an end segment 51 of the high corrugation 6 extending between an edge 52 of the plate 1 and the crossing 3 adjacent to this edge.
- the reinforcing piece 15 thus fixed has a length greater than the segment 51 to protrude from the edge of the plate 1 and be able to engage under a second adjacent plate, as will be explained below.
- the establishment of the reinforcing piece 15 at this position may be effected for example by a sharp blow of the hand on the end of the reinforcing piece 15 protruding from the plate 1.
- This implementation is simplified by the fact that the reinforcing piece 15 is guided axially in the corrugation 6 by the support of its upper wall 16 against the plate 1 inside the corrugation 6, and that the support of the lateral sides 42 of the plate 41 against the plate 1 inside the corrugation 6 holds the retaining tab 44 at a laterally centered position in the corrugation 6 at a height corresponding to that of the groove 18.
- the beveled shape of the leg portion 48 also facilitates guiding the retaining tab 44 in the entrance of the groove 18.
- an anchoring piece 30 can cooperate with two reinforcing pieces 15 and two reinforcing pieces 115 for retaining, alone or with the aid of other adjacent anchoring pieces, the four reinforcing pieces in the four ripple segments meeting at the crossing 3 where the anchor 30 is attached.
- a plate 1 having high corrugations 6 identical to each other and regularly spaced and low corrugations 5 identical to each other and evenly spaced it is therefore possible to equip all the corrugation segments of the plate 1 with pressure reinforcement pieces using only three sets of pieces, namely mutually identical anchoring pieces 30, mutually identical reinforcing pieces, having a length adapted to the distance between two low ripples 5, and mutually identical reinforcing pieces 15 having a length adapted to the distance between two high ripples 6.
- the plate 1 is turned over and supported against a support by For example, a wall, so that its outer face is visible and the high undulations 6 are substantially horizontal, the low undulations 5 being almost vertical.
- the alphabetical order of the reference letters shown in Figure 14 indicates the order of assembly of the parts.
- a first anchoring piece is placed in a cross located at a lower left corner of the plate 1.
- a reinforcing piece 15 and an anchoring piece 30 are placed sequentially following the high horizontal ripple (letters B to Q), so that the reinforcing pieces are each time in the support mode with the two adjacent anchors.
- Reinforcing pieces 115 are then placed in the low corrugation segments adjacent to the high corrugation which has just been equipped, each time making the lower end of the reinforcement piece 115 interact with the arm 140, the piece of reinforcement.
- underlying anchorage in the support mode (letters R).
- the next high corrugation is then carried out in the same manner as for the first upper corrugation, ensuring that each added anchor piece 30 retains a reinforcement piece 115 added to step R in the first corrugation mode. support (letters S, T, U, V, etc.).
- the end segments 51 of the high corrugations 6 and the end segments 83 of the low corrugations 5 are not equipped with reinforcement pieces.
- the method described with reference to FIG. 8 can be used to equip reinforcing pieces with the end segments located along one edge or several edges of the plate 1.
- the three batches of parts used in this method can be provided in the form of a reinforcing device in kit form for metal plates of the plate type 1.
- the mounting of such a reinforcing device on the plate 1 can be realized by hand in a quick and easy way by exerting relatively moderate manual efforts.
- Such a reinforcement kit is therefore also adapted to a corrugated metal plate having dimensions and numbers of corrugations different from those shown in FIG.
- corrugations of the corrugated metal plate to be equipped are unevenly distributed, the production of several batches of reinforcing pieces 15 or 115 having different lengths is easy, since these can be cut in a profile. of great length.
- the plate 1 and equipped with reinforcing pieces 15 and / or 115 retained by anchors 30 can be used as a modular wall structure to manufacture a pressure-resistant sealing membrane by assembling several of these structures.
- the interface between two of these structures can be made according to Figure 9.
- FIG. 9 shows schematically the interface between two corrugated metal plates 54 and 55 similar to the plate 1 of Figure 1, which are juxtaposed so that their respective undulations are aligned.
- FIG. 9 is a sectional view in the median plane of a high corrugation 6 which extends through the two plates 54 and 55.
- Each of the two plates 54 and 55 is equipped with the reinforcement device described above, to reinforce all the corrugations of the plates or a subset of them.
- these reinforcing devices are very partially represented, namely by a respective anchor 30 attached to each of the plates 54 and 55 at the crossing 3 of the high corrugation 6 which is closest to the edge 52 of the respective plate, and by a reinforcing piece 15 which is arranged in the high corrugation 6 partially under the plate 54 and partially under the plate 55.
- the reinforcing piece 15 thus reinforces the high corrugation 6 at the level of the interface between the two plates 54 and 55.
- To set up the plates 54 and 55 one can proceed as follows.
- the plate 54 already equipped with the reinforcing device is first placed on the support surface 60 on which the sealing membrane is to be mounted.
- the support surface 60 may consist of the upper plate of a thermal insulation barrier known elsewhere.
- the plate 54 carries the reinforcing piece 15 fixed to the anchoring piece 30 so as to protrude from the edge 52 of the plate 54 by a certain distance.
- the second plate 55 already equipped with the reinforcing device is then brought above the support surface 60 next to the plate 54 in a state parallel to the plate 54, so that the edge 52 of the plate 55 finally has to overlap the plate 54 is in height.
- the high corrugation 6 of the plate 55 does not include a reinforcement piece.
- This insertion set 58 may exist without it being necessary to make the reinforcing piece 15 to a different size from the other reinforcing pieces used inside the plates 54 and 55. If the plates 54 and 55 are dimensioned so that all the low corrugations 5 are finally equidistant, both within each of the plates 54 and 55 and at the interface between the two plates 54 and 55, taking into account their overlap, the reinforcing piece 15 of a length adapted to this uniform spacing is both capable of being supported on two retaining tabs 44 in the support mode illustrated in FIG. 6, and at the same time capable of being fixed to a single retaining tab 44 in the attachment mode illustrated in Figures 8 and 9, leaving the clearance 58 relative to the other retaining tab 44. .
- FIG. 13 represents a reinforcing piece 15 retained in a high corrugation 6 between two anchoring pieces 30. representation of plate 1 was completely omitted for clarity. The represented odds indicate:
- the two plates 54 and 55 may be sealingly welded at the marginal portion 56.
- the combination of several wall structures which has just been described with reference to FIG. 9 can be carried out similarly to all the high corrugations 6 of the plates 54 and 55. In addition, similar measurements can be used in the direction of the low corrugations 5.
- the retaining tab 44 provides two modes of cooperation between the parts 30 and 15: a type of support-type cooperation shown in FIG. 6 and a type of attachment-type cooperation mode shown in FIG. 8. As a variant these two modes of cooperation could be obtained using two separate parts of the anchor.
- the plate 41 provides both a positioning member of the arm 40 in the high corrugation 6 and an abutment member for the reinforcing piece 15 in the fixed state. Alternatively, these two functions could be fulfilled by separate elements.
- the technique described above for producing a waterproofing membrane can be used in various types of tanks, for example to form the primary waterproofing membrane of an LNG tank in a land installation or in a floating structure such as a ship LNG carrier or other.
- a cutaway view of a LNG tank 70 shows a sealed and insulated tank 71 of generally prismatic shape mounted in the double hull 72 of the ship.
- the wall of the tank 71 comprises a primary sealed barrier intended to be in contact with the LNG contained in the tank, a secondary sealed barrier arranged between the primary waterproof barrier and the double hull 72 of the ship, and two insulating barriers arranged respectively between the primary watertight barrier and the secondary watertight barrier and between the secondary watertight barrier and the double hull 72.
- loading / unloading lines 73 arranged on the upper deck of the ship can be connected, by means of appropriate connectors, to a marine or port terminal to transfer a cargo of LNG from or to the tank 71.
- FIG. 10 shows an example of a marine terminal including a loading and unloading station 75, an underwater pipe 76 and an onshore installation 77.
- the loading and unloading station 75 is a off-shore fixed installation comprising a movable arm 74 and a tower 78 which supports the movable arm 74.
- the movable arm 74 carries a bundle of insulated flexible pipes 79 that can be connected to the loading / unloading pipes 73.
- the movable arm 74 is adjustable. suitable for all models of LNG carriers.
- a connection pipe (not shown) extends inside the tower 78.
- the loading and unloading station 75 enables the loading and unloading of the LNG tank 70 from or to the shore facility 77.
- the underwater line 76 allows the transfer of the liquefied gas between the loading or unloading station 75 and the onshore installation 77 over a large distance, for example 5 km, which makes it possible to keep the tanker vessel 70 at great distance from the coast during the loading and unloading operations.
- pumps on board the ship 70 and / or pumps equipping the shore installation 77 and / or pumps equipping the loading and unloading station 75 are used.
