- 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.
- a high corrugation 6 further comprises, at each cross 3, a concave recess 10 on either side of the fold 4.
- a concave recess 10 has its concavity turned towards the inner face 2 of the plate 1 and has a double curvature.
- a first curvature visible in FIG. 1 is around an axis perpendicular to the mean plane of the plate 1.
- a second curvature visible in FIG. 5 is around an axis perpendicular to the plane of FIG. 5.

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.

- 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.
