Description

STRUCTURE CYLINDRIQUE COMPOSÉE D'ÉLÉMENTS RECTANGULAIRES CYLINDRICAL STRUCTURE COMPOSED OF RECTANGULAR ELEMENTS
La présente invention se rapporte à une structure cylindrique dont la paroi verticale et la paroi de fond comprennent une pluralité d'éléments rectangulaires adjacents, et en particulier à une cuve étanche et thermiquement isolée.The present invention relates to a cylindrical structure whose vertical wall and the bottom wall comprise a plurality of adjacent rectangular elements, and in particular to a sealed and thermally insulated tank.
Le document FR 1 457 617 décrit une cuve terrestre pour le stockage de gaz naturel liquéfié. Cette cuve comprend une membrane étanche composée de tôles métalliques ondulées. Dans un mode de réalisation, la paroi de fond circulaire est recouverte par une pluralité de tôles rectangulaires réparties par secteurs symétriques, et par des tôles de liaison entre secteurs. Cette disposition permet de recouvrir une grande partie de la surface de la paroi de fond avec des tôles rectangulaires. Toutefois, comme la paroi de fond est circulaire, il est nécessaire de prévoir des tôles spéciales non-rectangulaires entre les bords droits des tôles rectangulaires et la circonférence de la paroi de fond. Le nombre de tôles différentes nécessaire pour recouvrir toute la paroi de fond est donc élevé.The document FR 1 457 617 describes a tank for the storage of liquefied natural gas. This tank comprises a waterproof membrane made of corrugated metal sheets. In one embodiment, the circular bottom wall is covered by a plurality of rectangular sheets distributed by symmetrical sectors, and by connecting plates between sectors. This arrangement makes it possible to cover a large part of the surface of the bottom wall with rectangular sheets. However, since the bottom wall is circular, it is necessary to provide special non-rectangular sheets between the straight edges of the rectangular sheets and the circumference of the bottom wall. The number of different sheets needed to cover the entire bottom wall is high.
Le document FR 2 739 675 décrit une cuve dont la paroi de fond est recouverte par une pluralité de tôles ondulées. Les tôles ondulées présentent des bords radiaux. La découpe de ces tôles est donc plus compliquée que dans le cas de tôles rectangulaires, et peut entraîner une quantité importante de chute, ce qui est particulièrement indésirable quand les tôles sont réalisées dans un matériau coûteux. De plus, différents types de tôles à bords radiaux sont nécessaires pour recouvrir toute la paroi de fond.The document FR 2 739 675 describes a vessel whose bottom wall is covered by a plurality of corrugated sheets. Corrugated sheets have radial edges. The cutting of these sheets is more complicated than in the case of rectangular sheets, and can cause a significant amount of drop, which is particularly undesirable when the sheets are made of an expensive material. In addition, different types of sheets with radial edges are required to cover the entire bottom wall.
Le document FR 2 398 961 décrit une cuve dont la paroi de fond est recouverte par une pluralité de virures rectangulaires toutes parallèles entre elles. Cela implique des difficultés de raccordement au niveau de l'intersection de la paroi de fond avec la paroi verticale de la cuve. De plus, la découpe des virures entraîne une quantité importante de chute.The document FR 2 398 961 describes a vessel whose bottom wall is covered by a plurality of rectangular strakes all parallel to each other. This involves connection difficulties at the intersection of the bottom wall with the vertical wall of the tank. In addition, the cutting strakes causes a significant amount of falling.
Le problème que la présente invention cherche à résoudre est de proposer une structure cylindrique ou une cuve, qui ne présente pas au moins certains des inconvénients précités de l'art antérieur, et en particulier qui puisse être réalisée avec un nombre réduit de formes pour les pièces.The problem that the present invention seeks to solve is to propose a cylindrical structure or a vessel, which does not exhibit at least some of the aforementioned disadvantages of the prior art, and particular that can be achieved with a reduced number of forms for parts.
La solution proposée par l'invention est une structure cylindrique comprenant une paroi verticale et une paroi de fond, ladite paroi de fond présentant une pluralité de secteurs images les uns des autres par rotation, chaque secteur comprenant une pluralité d'éléments rectangulaires adjacents, caractérisée par le fait que ladite paroi de fond a la forme d'un polygone régulier dont chaque côté correspond à un desdits secteurs, les bords des éléments rectangulaires d'un secteur étant respectivement perpendiculaires et parallèles au côté du polygone correspondant audit secteur.The solution proposed by the invention is a cylindrical structure comprising a vertical wall and a bottom wall, said bottom wall having a plurality of image sectors of each other by rotation, each sector comprising a plurality of adjacent rectangular elements, characterized in that said bottom wall has the shape of a regular polygon, each side of which corresponds to one of said sectors, the edges of the rectangular elements of a sector being respectively perpendicular and parallel to the side of the polygon corresponding to said sector.
Grâce à ces caractéristiques, une grande partie de la paroi de fond peut être composée d'éléments rectangulaires. De plus, les éléments rectangulaires de la paroi de fond peuvent s'étendre jusqu'aux côtés rectilignes de la paroi de fond, et dans ce cas aucun élément spécial n'est nécessaire entre les éléments rectangulaires et les côtés. Les éléments rectangulaires de la paroi de fond peuvent également s'étendre jusqu'à une faible distance des côtés rectilignes de la paroi de fond, et présenter des bords parallèles aux côtés. Dans ce cas la paroi de fond peut être complétée facilement par des éléments rectilignes qui s'étendent le long des côtés de la paroi de fond, par exemple des cornières d'angles. Dans les deux, cas, seul un nombre limité d'éléments différents est nécessaire pour former toute la paroi de fond.Thanks to these characteristics, a large part of the bottom wall can be composed of rectangular elements. In addition, the rectangular elements of the bottom wall can extend to the rectilinear sides of the bottom wall, and in this case no special elements are needed between the rectangular elements and the sides. The rectangular elements of the bottom wall may also extend to a short distance from the straight sides of the bottom wall, and have edges parallel to the sides. In this case the bottom wall can be completed easily by rectilinear elements which extend along the sides of the bottom wall, for example corner angles. In both cases, only a limited number of different elements are needed to form the entire bottom wall.
De préférence, ladite paroi de fond comprend une pluralité d'éléments de liaison polygonaux identiques reliant deux secteurs adjacents.Preferably, said bottom wall comprises a plurality of identical polygonal connecting elements connecting two adjacent sectors.
Ainsi on limite le nombre d'éléments différents nécessaire. Les éléments de liaison peuvent par exemple être des quadrilatères ou des octogones. Avantageusement, ladite paroi verticale comprend une pluralité d'éléments rectangulaires adjacents, lesdits éléments rectangulaires de la paroi verticale étant identiques aux éléments rectangulaires de la paroi de fond.Thus we limit the number of different elements necessary. The connecting elements may for example be quadrilaterals or octagons. Advantageously, said vertical wall comprises a plurality of adjacent rectangular elements, said rectangular elements of the vertical wall being identical to the rectangular elements of the bottom wall.
Dans ce cas, le nombre d'éléments différents nécessaire pour former la paroi de fond et la paroi verticale est limité. L'invention propose également une cuve étanche et thermiquement isolée, comprenant une barrière d'étanchéité et une barrière thermiquement isolante, caractérisée par le fait qu'elle comprend une structure cylindrique selon l'invention ci-dessus. Dans ce cas, les éléments rectangulaires peuvent êtres des éléments de la barrière étanche et/ou de la barrière thermiquement isolante. Par exemple lesdits éléments rectangulaires comprennent des tôles ondulées formant la barrière d'étanchéité ou des virures métalliques à bords relevés formant la barrière d'étanchéité. On peut aussi prévoir que lesdits éléments rectangulaires comprennent des panneaux en matériau thermiquement isolant formant la barrière thermiquement isolante.In this case, the number of different elements necessary to form the bottom wall and the vertical wall is limited. The invention also proposes a sealed and thermally insulated tank, comprising a sealing barrier and a thermally insulating barrier, characterized in that it comprises a cylindrical structure according to the invention above. In this case, the rectangular elements may be elements of the sealed barrier and / or the thermally insulating barrier. For example, said rectangular elements comprise corrugated sheets forming the sealing barrier or metal strakes with raised edges forming the sealing barrier. It can also be provided that said rectangular elements comprise panels of thermally insulating material forming the thermally insulating barrier.
De préférence, ladite paroi de fond comprend une pièce centrale à laquelle les éléments rectangulaires les plus centraux de chaque secteur sont reliés.Preferably, said bottom wall comprises a central piece to which the most central rectangular elements of each sector are connected.
Selon un mode de réalisation particulier, la cuve comprend une cornière d'angle rectiligne agencée le long d'un côté de ladite paroi de fond, ladite cornière d'angle comprenant une latte horizontale à laquelle sont reliés les éléments rectangulaires les plus excentrés d'un secteur et une latte verticale à laquelle sont reliés des éléments rectangulaires de la paroi verticale.According to a particular embodiment, the vessel comprises a rectilinear angle bracket arranged along one side of said bottom wall, said corner angle comprising a horizontal lath to which are connected the most eccentric rectangular elements of a sector and a vertical lath to which are connected rectangular elements of the vertical wall.
Une telle cornière permet de facilement relier les éléments de la paroi de fond à ceux de la paroi verticale.Such an angle makes it easy to connect the elements of the bottom wall to those of the vertical wall.
L'invention sera mieux comprise, et d'autres buts, détails, caractéristiques et avantages de celle-ci apparaîtront plus clairement au cours de la description suivante de plusieurs modes de réalisation particuliers de l'invention, donnés uniquement à titre illustratif et non limitatif, en référence aux dessins annexés.

Sur les figures 6 et 7, on a représenté la membrane étanche d'une cuve terrestre 1 pour le stockage de gaz naturel liquéfié (GNL). La cuve 1 comprend également une structure porteuse en béton et une barrière thermiquement isolante située entre la membrane étanche et la structure porteuse, qui ne sont pas représentées.Figures 6 and 7, there is shown the sealed membrane of a tank 1 for the storage of liquefied natural gas (LNG). The vessel 1 also comprises a concrete support structure and a thermally insulating barrier located between the waterproof membrane and the supporting structure, which are not shown.
La membrane étanche de la cuve 1 est une structure cylindrique qui comprend une paroi de fond 2 et une paroi verticale 3. La paroi de fond 2 a la forme d'un polygone régulier, à vingt côtés 6 dans l'exemple représenté sur les figures 6 et 7. Toutefois l'invention concerne d'autres types de polygones, notamment à cinq côtés ou plus.The sealed membrane of the tank 1 is a cylindrical structure which comprises a bottom wall 2 and a vertical wall 3. The bottom wall 2 has the shape of a regular polygon, with twenty sides 6 in the example shown in the figures 6 and 7. However, the invention relates to other types of polygons, in particular with five or more sides.
La paroi de fond 2 présente une pluralité de secteurs 4 correspondant chacun à un côté 6. Les secteurs 4 sont images les uns des autres par rotation. La paroi verticale 2 est composée d'une pluralité de pans 5 verticaux correspondant chacun à un côté 6. La paroi de fond 2 et la paroi verticale 3 sont composées d'une pluralité de tôles métalliques reliées entre elles par soudage, et qui présentent des ondulations permettant la contraction des tôles lors des variations de température. La fixation et le soudage des tôles ainsi que la formation des ondulations peuvent se faire selon des techniques connues dans le domaine des cuves de stockage ou de transport de GNL.The bottom wall 2 has a plurality of sectors 4 each corresponding to one side 6. The sectors 4 are images of each other by rotation. The vertical wall 2 is composed of a plurality of vertical sections 5 each corresponding to one side 6. The bottom wall 2 and the vertical wall 3 are composed of a plurality of metal sheets joined together by welding, and which have corrugations allowing the contraction of the sheets during the variations of temperature. The fixing and welding of the sheets and the formation of the corrugations can be done according to techniques known in the field of LNG storage tanks or transport.
Sur la paroi de fond 2, les tôles métalliques comprennent des tôles rectangulaires 8 de longueur L et de largeur 1, représentées sur la figure 3, ainsi que des tôles de liaison 9 en forme de quadrilatère symétrique, présentant deux côtés de longueur L et deux côtés de longueur 1/2, représentées sur la figure 2. La figure 1 montre comment les tôles rectangulaires 8 sont disposées pour recouvrir un secteur 4 de la paroi de fond 2. Une pluralité de tôles rectangulaires 8 sont disposées selon trois rangées, avec leur largeur parallèle au côté 6. D'une rangée à l'autre, les tôles rectangulaires 8 sont agencées en quinconce et il y a chaque fois une tôle 8 de moins au fur et à mesure qu'on se rapproche du centre. Bien entendu, en fonction des dimensions de la paroi de fond 2 et des tôles rectangulaires 8, il pourra y avoir plus ou moins de trois rangées. Par exemple dans le mode de réalisation de la figure 7 il y a dix rangées. Grâce à la disposition des tôles rectangulaires 8 décrite ci- dessus, l'espace laissé libre entre une tôle 8 située à l'extrémité d'une rangée d'un premier secteur et la tôle 8 située à l'extrémité d'une rangée correspondante d'un deuxième secteur adjacent, présente toujours une forme identique de quadrilatère symétrique. Tous ces espaces de forme identique peuvent donc être occupés par une pluralité de tôles de liaison 9.On the bottom wall 2, the metal sheets comprise rectangular plates 8 of length L and width 1, represented in FIG. 3, as well as symmetrical quadrilateral connecting plates 9 having two sides of length L and two sides of length 1/2, shown in Figure 2. FIG. 1 shows how the rectangular plates 8 are arranged to cover a sector 4 of the bottom wall 2. A plurality of rectangular plates 8 are arranged in three rows, with their width parallel to the side 6. From one row to the other other, the rectangular sheets 8 are arranged in staggered rows and there is each time a sheet 8 less as one gets closer to the center. Of course, depending on the dimensions of the bottom wall 2 and the rectangular plates 8, there may be more or less than three rows. For example in the embodiment of Figure 7 there are ten rows. With the arrangement of the rectangular sheets 8 described above, the space left free between a sheet 8 located at the end of a row of a first sector and the sheet 8 at the end of a corresponding row. of a second adjacent sector, always presents an identical form of symmetrical quadrilateral. All these spaces of identical shape can therefore be occupied by a plurality of connecting plates 9.
Ainsi, comme dans l'exemple représenté sur la figure 1, la largeur des tôles rectangulaires 8 les plus extérieures est confondue avec le côté 6, la paroi de fond 2 peut être entièrement composée avec une pluralité de tôles rectangulaires 8 identiques, une pluralité de tôles de liaison 9 identiques, et une pièce centrale 13, qui peut éventuellement être formée par des tôles de liaison 9 comme le montre la figure 7. La paroi de fond 2 est donc composée de deux ou, au plus, de trois types de tôles différentes. Dans un mode de réalisation non représenté, le petit côté des tôles rectangulaires 8 les plus extérieures n'est pas confondu avec le côté 6, mais s'en trouve à faible distance, par exemple 10 cm. Une cornière d'angle rectiligne à section en forme de L est disposée le long du côté 6. La cornière d'angle comprend une latte horizontale à laquelle sont reliées les tôles rectangulaires 8 les plus excentrées, par leur largeur. La cornière d'angle comprend également une latte verticale à laquelle sont reliées les tôles de la paroi verticale. La cornière d'angle n'est qu'un exemple de liaison entre la paroi de fond 2 et la paroi verticale 3. Cette liaison peut être réalisée selon d'autres techniques, par exemple de manière similaire aux anneaux de raccordement utilisés dans le domaine de cuve de transport de GNL. Quelle que soit la technique choisie, comme il s'agit de réaliser une liaison entre deux parois perpendiculaires composées principalement de tôles rectangulaires dont les bords sont parallèles et perpendiculaires à l'arrête d'intersection, cette liaison est relativement simple et ne nécessite qu'un nombre limité de pièces. La paroi verticale 3 est composée de tôles métalliques rectangulaires. Dans un mode de réalisation, il s'agit des mêmes tôles rectangulaires 8 que celles de la paroi de fond 2, ce qui permet de limiter le nombre de types de tôles nécessaire. Au niveau des côtés 6, les ondulations longitudinales 7 de la paroi de fond 2 peuvent être reliées aux ondulations longitudinales 7 correspondantes de la paroi verticale 3, ce qui permet de limiter les contraintes dues à la contraction thermique.Thus, as in the example shown in FIG. 1, the width of the outermost rectangular plates 8 coincides with the side 6, the bottom wall 2 can be entirely composed with a plurality of identical rectangular plates 8, a plurality of 9 identical connecting plates, and a central piece 13, which may optionally be formed by connecting plates 9 as shown in Figure 7. The bottom wall 2 is composed of two or, at most, three types of sheets different. In an embodiment not shown, the short side of the outermost rectangular plates 8 is not coincident with the side 6, but is at a short distance, for example 10 cm. A rectilinear corner angle L-shaped section is disposed along the side 6. The corner angle comprises a horizontal slat to which are connected the rectangular plates 8 the most eccentric, by their width. The corner angle also comprises a vertical slat to which are connected the sheets of the vertical wall. The corner angle is only an example of connection between the bottom wall 2 and the vertical wall 3. This connection can be made according to other techniques, for example in a manner similar to the connecting rings used in the field. of LNG transport tank. Whatever technique you choose, as it is a link between two perpendicular walls composed mainly of rectangular sheets whose edges are parallel and perpendicular to the intersection stop, this connection is relatively simple and requires only a limited number of parts. The vertical wall 3 is composed of rectangular metal sheets. In one embodiment, it is the same rectangular sheets 8 as those of the bottom wall 2, which limits the number of types of metal required. At the sides 6, the longitudinal corrugations 7 of the bottom wall 2 can be connected to the corresponding longitudinal corrugations 7 of the vertical wall 3, which limits the constraints due to thermal contraction.
Comme dit précédemment, les tôles présentent des ondulations permettant leur contraction lors des variations de température. Plus précisément, les tôles rectangulaires 8 présentent deux ondulations longitudinales 7 et une pluralité d'ondulations transversales 10. Les ondulations longitudinales 7 sont située à une distance a des bords longs et à une distance b = 2a l'une de l'autre. Comme on peut le voir sur la figure 1 notamment, les ondulations 7 et 10 des tôles rectangulaires 8 sont reliées entre elles. Les tôles de liaison 9 présentent également des ondulations reliées aux ondulations des tôles rectangulaires 8 adjacentes. Dans l'exemple de la figure 4, la tôle de liaison 9 comprend des ondulations terminales 11 reliées à des ondulations longitudinales 7, et des ondulations de liaison 12 reliées aux ondulations transversales 10 des tôles rectangulaires 8 adjacentes. D'autres dispositions des ondulations sur les tôles de liaison 9 sont envisageables et un exemple est représenté sur la figure 6.As said before, the sheets have corrugations allowing their contraction during temperature variations. More precisely, the rectangular plates 8 have two longitudinal corrugations 7 and a plurality of transverse corrugations 10. The longitudinal corrugations 7 are located at a distance from long edges and at a distance b = 2a from one another. As can be seen in FIG. 1 in particular, the corrugations 7 and 10 of the rectangular plates 8 are interconnected. The connecting plates 9 also have corrugations connected to the corrugations of the adjacent rectangular plates 8. In the example of Figure 4, the connecting plate 9 comprises end corrugations 11 connected to longitudinal corrugations 7, and connecting corrugations 12 connected to the transverse corrugations 10 adjacent rectangular plates 8. Other provisions of the corrugations on the connecting plates 9 are conceivable and an example is shown in FIG.
La figure 5 représente un agencement différent des tôles de la paroi de fond 2. Dans ce mode de réalisation il y a, au niveau de chaque tôle de liaison 9, deux tôles rectangulaires 8' de moins au fur et à mesure qu'on se rapproche du centre. Dans ce mode de réalisation, au lieu d'utiliser des tôles rectangulaires 8 qui présentent toutes la même longueur L correspondant à la longueur d'un côté des tôles de liaison 9, on peut utiliser des tôles rectangulaires 8' de longueurs différentes, qui s'étendent par exemple depuis le côté 6 de la paroi de fond jusqu'à un petit bord d'une tôle de liaison. Ces tôles rectangulaires 8' peuvent par exemple des virures à bords relevés, dont la fabrication et la fixation sur des supports de soudure sont connues dans le domaine des cuves de stockage ou de transport de GNL. De telles virures peuvent être réalisées en matériau à faible coefficient de dilatation, par exemple en Invar, et ne sont pas pourvues d'ondulations. La barrière thermiquement isolante de la cuve 1 n'a pas été représentée. Elle peut être composée d'une pluralité de panneaux isolants. Dans un mode de réalisation, les panneaux de la paroi de fond comprennent des panneaux rectangulaires et des panneaux de liaison agencés de manière similaire aux tôles rectangulaires 8 et aux tôles de liaison 9, respectivement.FIG. 5 shows a different arrangement of the sheets of the bottom wall 2. In this embodiment, there is, at each connecting plate 9, two rectangular sheets 8 'less as one goes closer to the center. In this embodiment, instead of using rectangular plates 8 which all have the same length L corresponding to the length of one side of the connecting plates 9, it is possible to use rectangular plates 8 'of different lengths, which are extend for example from the side 6 of the bottom wall to a small edge of a connecting plate. These rectangular sheets 8 'may for example strakes with raised edges, the manufacture and fixing on soldering supports are known in the field of LNG storage or transport tanks. Such strakes can be made of low coefficient of expansion material, for example Invar, and are not provided with corrugations. The thermally insulating barrier of the vessel 1 has not been shown. It can be composed of a plurality of insulating panels. In one embodiment, the panels of the bottom wall comprise rectangular panels and connecting panels arranged similarly to the rectangular plates 8 and the connecting plates 9, respectively.
On a décrit des tôles de liaison 9 en forme de quadrilatère, deux tôles 9 se touchant uniquement au niveau de sommets respectifs comme on peut le voir sur les figures 1 et 5. Dans un autre mode de réalisation représenté sur la figure 8, les tôles de liaison 9' présentent une forme de quadrilatère à sommet coupé, formant ainsi un hexagone, et deux tôles de liaison 9' adjacentes sont en contact au niveau de deux côtés.Quadrilateral-shaped connecting plates 9 have been described, two plates 9 touching only at respective vertices, as can be seen in FIGS. 1 and 5. In another embodiment shown in FIG. link 9 'have a cut-off quadrilateral shape, thereby forming a hexagon, and two adjacent connecting plates 9' are in contact at two sides.
La présente invention n'est pas limitée aux cuves. Au contraire elle concerne toute structure cylindrique comprenant une paroi de fond polygonale composée d'éléments rectangulaires répartis en secteurs et d'éléments de liaison entre secteurs.The present invention is not limited to tanks. On the contrary, it concerns any cylindrical structure comprising a polygonal bottom wall composed of rectangular elements distributed in sectors and connecting elements between sectors.
Bien que l'invention ait été décrite en liaison avec plusieurs modes de réalisation particuliers, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention. Although the invention has been described in connection with several particular embodiments, it is obvious that it is not limited thereto and that it comprises all the technical equivalents of the means described and their combinations if they are within the scope of the invention.
