Definitions

• the present invention relates to a tank for the storage of cryogenic fluid, for example liquefied natural gas (LNG).
• cryogenic fluid for example liquefied natural gas (LNG).
• the document FR 2 912 385 describes a land tank for LNG.
• This tank has a concrete support structure, at least one sealed barrier and at least one thermally insulating barrier.
• the thermally insulating barrier can be made by a plurality of adjacent panels. Each panel must be attached to the concrete support structure. For this, it is known to use studs anchored in the concrete carrying structure and penetrating the concrete. Usually, for a panel of rectangular section, the studs are arranged at each corner of the panel, and possibly along the sides of the panel.
• the number of studs to be anchored in the concrete is therefore high.
• the position of the studs is imposed by the position of the panels, which can be problematic when the concrete does not allow anchoring in the desired position. Such an impossibility can come for example from a failed drilling or a local malfunction of the concrete.
• the document FR 1 546 524 describes a solution in which two adjacent panels are connected to the concrete wall by a tie rod anchored in the concrete and connected to a plate bearing on brackets secured to the panels.
• a tie rod is common to two adjacent panels, the number of anchors to be made in the concrete is limited. However, the tie rod must pass between the two adjacent panels. Thus, it is necessary to provide a minimum distance between two adjacent panels. This distance can not be arbitrarily low or even zero.
• a problem that the present invention proposes to solve is to provide a tank for the storage of cryogenic fluid, which does not have at least some of the aforementioned drawbacks of the prior art.
• an object of the invention is to reduce the number of anchors required in concrete.
• Another object of the invention is to be able to position the anchor points in the concrete more freely.
• Another object of the invention is to be able to position two adjacent panels as close to each other as desired.
• the solution proposed by the invention is a tank for the storage of cryogenic fluid, comprising a concrete carrier structure, at least one sealed barrier and at least one thermally insulating barrier, wherein the thermally insulating barrier comprises a plurality of panels fixed to said carrier structure, wherein said panels comprise at least two adjacent first panels fixed to the supporting structure by a common fastener, characterized in that said fastener comprises a plate, a first stud which extends from a first side of the plate and at least a second stud and a third stud extending from a second side of the plate, the first stud being anchored in the bearing structure, the second stud and the third stud being each anchored in a said first respective panels.
• said panels comprise at least two adjacent second panels, the fastener further comprising a fourth stud and a fifth stud, the fourth stud and the fifth stud being each anchored in one of said respective second panels.
• said first panels and said second panels each have a rectangular section, the fastener being located at four adjacent corners of said first panels and said second panels.
• said first panels each have a rectangular section, the fastener being disposed along two adjacent edges of said first panels and said second panels.
• said first panels are in contact with each other.
• said first stud is closer to the second stud than to the third stud.
• the anchoring of the first stud can be deported.
• FIG. 1 is a perspective view of a fastener of a tank according to one embodiment of the invention
• FIG. 2 is an exploded view of the fastener of FIG. 1.
• a vessel according to one embodiment of the invention is a land tank for LNG.
• the vessel comprises a concrete support structure, a sealed barrier and a thermally insulating barrier.
• the tank may also comprise, on a part or all of its walls, a second sealed barrier and a second thermally insulating barrier.
• the thermally insulating barrier is made with adjacent panels fixed to the supporting structure.
• a panel has a rectangular section and comprises a block of foam disposed on a plywood plate.
• Figures 1 and 2 show a vertical wall 1 concrete and a fastener.
• the wall 1 is part of the bearing structure of the tank.
• the fixing member comprises a metal plate 2, a first stud 3, a second stud 4, a third stud 5, a fourth stud 6 and a fifth stud 7.
• the plate 2 is rectangular and disposed facing the wall 1.
• the stud 3 extends on the side of the plate 2 facing the wall 1, perpendicularly to the plate 2. It is anchored in an orifice 8 pierced in the wall 1 and is fixed to the plate 2 by bolting, passing through a hole 9 formed in the plate 2.
• the stud 3 comprises a cup
• the cup 10 which delineates the portion of the stud 3 inserted in the orifice 8 and that which serves for attachment to the plate 2.
• the cup 10 allows the restoration of the seal between the stud 3 and the vapor barrier of the concrete.
• the studs 4, 5, 6 and 7 extend on the side of the plate 2 opposite the wall 1, perpendicular to the plate 2. They are respectively welded to the four corners of the plate 2.
• the thermally insulating barrier are arranged with four respective corners next to each other, in front of the fastener.
• Each of the studs 4, 5, 6 and 7 is anchored in the corner of one of the four respective panels.
• the fastener makes it possible to connect four corners of four adjacent panels to the support structure, by realizing only one anchoring point for the stud 3.
• the adjacent panels can be as close as one of the other as desired, for example in contact with each other.
• the stud 3 is located in the center of the plate 2. However, if the center of the plate 2, which is positioned taking into account the arrangement of the panels, is not a suitable place to drill the orifice 8, the stud 3 can be positioned differently. For this, during assembly, the hole 9 and the orifice 8 are made in a suitable position.
• the stud 3 is not necessarily at the same distance from the studs 4, 5, 6 and 7. Thus, the fastener allows to deport the anchor point with respect to the position of the panels, if necessary.
• the fastener could comprise a different number of studs on the opposite side to the wall 1.
• two studs are sufficient .
