Description

L'invention concerne généralement une structure de support d'équipements industriels, qui peut servir d'une part de barge flottante permettant de transporter ces équipements industriels de leur lieu de fabrication jusqu'à leur site d'utilisation, et d'autre part de fondation dans le sol quand ces équipements sont implantés sur leur site d'utilisation.The invention generally relates to a support structure for industrial equipment, which can be used on the one hand as a floating barge for transporting this industrial equipment from its place of manufacture to its site of use, and on the other hand foundation in the ground when these equipments are installed on their site of use.

Il est déjà connu dans la technique actuelle de monter des équipements industriels sur une structure porteuse qui peut servir également de barge de transport par mer. Ces structures connues présentent des inconvénients divers : elles doivent avoir une rigidité et une résistance mécaniques importantes, car elles doivent pouvoir naviguer en haute mer et supporter des contraintes très grandes sans se déformer de façon importante. Il en résulte donc un poids élevé et un tirant d'eau important. Comme ces structures doivent être échouées sur le site d'utilisation des équipements industriels, leur poids et leur tirant d'eau importants obligent à de gros travaux de génie civil sur le site d'utilisation. Quand ces structures sont enfouies dans le sol pour servir de fondation, elles sont soumises à une corrosion importante. De plus, pour le transport en mer, elles doivent être compartimentées et équipées de systèmes de ballastage.It is already known in the current technique to mount industrial equipment on a load-bearing structure which can also serve as a barge for transport by sea. These known structures have various drawbacks: they must have significant rigidity and mechanical strength, because they must be able to navigate on the high seas and withstand very large constraints without significantly deforming. This therefore results in a high weight and a large draft. As these structures must be stranded at the site of use of industrial equipment, their significant weight and draft require major civil engineering work at the site of use. When these structures are buried in the ground to serve as a foundation, they are subject to significant corrosion. In addition, for transport in at sea, they must be compartmentalized and equipped with ballast systems.

La présente invention a précisément pour but essentiel d'éviter les inconvénients précités tout en simplifiant et en réduisant de façon très importante le prix de revient d'une telle structure.The main object of the present invention is precisely to avoid the aforementioned drawbacks while simplifying and considerably reducing the cost price of such a structure.

Elle propose donc une structure de support d'équipemerts industriels, destinée à servir d'une part de barge flottante pour le transport desdits équipements, et d'autre part de fondation dans le sol quand les équipements sont implantés sur leur site d'utilisation, caractérisée en ce qu'elle est constituée essentiellement d'un ensemble unitaire de compartiments creux adjacents à fond ouvert, fermés de façon étanche à leur partie supérieure.It therefore proposes a support structure for industrial equipment, intended to serve on the one hand as a floating barge for the transport of said equipment, and on the other hand as a foundation in the ground when the equipment is installed on their site of use, characterized in that it essentially consists of a unitary set of adjacent hollow compartments with an open bottom, sealed in their upper part.

La structure selon l'invention est du type alvéolaire, fermée de façon étanche à sa partie supérieure, mais à fond ouvert, et qui peut donc flotter en raison de l'air qui est emprisonné dans les compartiments précités.The structure according to the invention is of the cellular type, sealed in its upper part, but with an open bottom, and which can therefore float due to the air which is trapped in the above-mentioned compartments.

La structure selon l'invention est beaucoup plus légère que les structures connues du même type, et elle .a également un prix de revient beaucoup moins élevé, pour un même matériau.The structure according to the invention is much lighter than known structures of the same type, and it also has a much lower cost price, for the same material.

L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés, donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels :

  • La figure 1 est une vue schématique en perspective d'une structure porteuse d'équipements industriels selon l'invention; la figure 2 est une vue partielle en perspective avec arrachement partiel de cette structure; la figure 3 est une vue en coupe longitudinale schématique d'une structure selon l'invention, servant de barge flottante; la figure 4 est une vue partielle schématique en coupe montrant la fixation d'un tube de réglage de poussée hydrostatique dans un compartiment d'une structure selon l'invention; la figure 5 représente schématiquement la division de cette structure en différentes zones correspondant à la répartition des charges sur ladite structure; et les figures 6 et 7 représentent schématiquement deux modes de fixation d'une charge sur la structure porteuse selon l'invention.
The invention will be better understood, and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings, given solely by way of example illustrating an embodiment of the invention and in which:
  • Figure 1 is a schematic perspective view of a supporting structure of industrial equipment according to the invention; Figure 2 is a partial perspective view with partial cutaway of this structure; Figure 3 is a schematic longitudinal sectional view of a structure according to the invention, serving as a floating barge; Figure 4 is a schematic partial sectional view showing the attachment of a hydrostatic thrust adjustment tube in a compartment of a structure according to the invention; FIG. 5 schematically represents the division of this structure into different zones corresponding to the distribution of the loads on said structure; and FIGS. 6 and 7 schematically represent two methods of fixing a load on the support structure according to the invention.

On a donc représenté schématiquement en figure 1 une structure porteuse selon l'invention, désignée généralement par la référence 10, et les équipements industriels 11 qu'elle supporte sur sa face supérieure. A titre d'exemple, et pour fixer les idées, on précisera que la structure porteuse 10 selon l'invention a ici une forme rectangulaire avec une longueur d'une centaine de mètres environ, une largeur d'une trentaine de mètres, et une hauteur de 1,5 à 2 mètres.There is therefore shown diagrammatically in FIG. 1 a support structure according to the invention, generally designated by the reference 10, and the industrial equipment 11 that it supports on its upper face. By way of example, and to fix the ideas, it will be specified that the supporting structure 10 according to the invention has here a rectangular shape with a length of about a hundred meters, a width of about thirty meters, and a height of 1.5 to 2 meters.

Comme on le voit plus clairement en figure 2, cette structure 10 est constituée essentiellement par un réseau de poutres rigides horizontales 12, qui se croisent perpendiculairement les unes les autres, et qui définissent entre elles les compartiments rectangulaires 13. Ces poutres 12 ont une section transversale sensiblement en T renversé, comprenant une âme verticale et une semelle inférieure 14.As can be seen more clearly in FIG. 2, this structure 10 consists essentially of a network of horizontal rigid beams 12, which intersect each other perpendicularly, and which define between them the rectangular compartments 13. These beams 12 have a section transverse substantially in inverted T, comprising a vertical core and a bottom sole 14.

Elles sont avantageusement pourvues de pattes verticales de raidissement 15 solidaires des âmes des poutres 12.They are advantageously provided with vertical stiffening lugs 15 integral with the webs of the beams 12.

Les compartiments 13 adjacents, définis par les pou- très 12 longitudinales et transversales, sont fermés de façon étanche à leur partie supérieure par une plaque mince 16 de matériau approprié, tandis que leur partie inférieure ou leur fond reste ouvert.The adjacent compartments 13, defined by the longitudinal and transverse powders 12, are sealed in their upper part by a thin plate 16 of suitable material, while their lower part or their bottom remains open.

La structure 10 ainsi constituée est donc du type alvéolaire, comportant un très grand nombre de compartiments 13 adjacents, isolés les uns des autres, fermés de façon étanche à leur partie supérieure par la plaque mince 16, et qui sont à fond ouvert. La plaque supérieure 16 sert uniquement de peau d'étanchéité. Pour fixer les idées, on peut préciser, à titre d'exemple non limitatif, que les compartiments 13 ont des dimensions de l'ordre de 3 x 6 m, et que la plaque mince supérieure 16 a une épaisseur de l'ordre de 0,7 à 1 mm, quand elle est en acier.The structure 10 thus formed is therefore of the cellular type, comprising a very large number of adjacent compartments 13, isolated from each other, sealed in their upper part by the thin plate 16, and which are open bottom. The upper plate 16 only serves as a sealing skin. To fix the ideas, it can be specified, by way of nonlimiting example, that the compartments 13 have dimensions of the order of 3 x 6 m, and that the upper thin plate 16 has a thickness of the order of 0 , 7 to 1 mm, when it is made of steel.

La structure 10 selon l'invention diffère donc essentiellement des structures connues de la technique antérieure en ce qu'elle ne comprend pas de fond et en ce qu'elle présente un poids beaucoup moins important pour un même matériau. On peut admettre de façon générale que les poids, et les prix de revient, d'une structure selon l'invention et d'une structure selon la technique antérieure sont dans un rapport de 1:4 ou 1:3.The structure 10 according to the invention therefore essentially differs from the structures known from the prior art in that it does not include a bottom and in that it has a much less weight for the same material. It can be generally accepted that the weights, and the cost prices, of a structure according to the invention and of a structure according to the prior art are in a ratio of 1: 4 or 1: 3.

Dans les figures 3 et 4, on a représenté de façon schématique les moyens utilisés selon l'invention pour régler dans les compartiments 13, quand la structure est utilisée en barge flottante, la poussés hydrostatique en fonction de la charge supportée au niveau des divers compartiments.In Figures 3 and 4, there is shown schematically the means used according to the invention for adjusting in the compartments 13, when the structure is used in floating barge, the hydrostatic thrust as a function of the load supported at the various compartments .

On sait que, en théorie, la poussée hydrostatique exercée sur une structure compartimentée ou alvéolaire, doit être proportionnelle à la charge en chaque point de la structure. A l'endroit où une charge maximum est'appliquée, la poussée hydrostatique doit être maximum; dans un endroit ne supportant pas de charges, la poussée hydrostatique doit être nulle, et dans un endroit supportant une charge moyenne, la poussée hydrostatique doit être moyenne.We know that, in theory, the hydrostatic thrust exerted on a compartmentalized or alveolar structure must be proportional to the load at each point of the structure. At the point where a maximum load is applied, the hydrostatic thrust must be maximum; in a place with no load, the hydrostatic thrust must be zero, and in a place with a medium load, the hydrostatic thrust must be average.

Selon la présente invention, les compartiments 13 ne comprennent pas de fond, et on règle la poussée hydros- . tatique dans chaque compartiment, en laissant pénétrer l'eau jusqu'à une certaine hauteur à l'intérieur de ces compartiments. Cette caractéristique de l'invention est représentée schématiquement en figure 3. Dans cette figure, la structure 10 est représentée flottant sur un plan d'eau. Les compartiments 13a, 13c, 13d et 13e sont représentés pourvus de moyens faisant communiquer sélectivement l'intérieur de ces compartiments avec l'atmosphère extérieure. Ces moyens sont constitués par des tubes 17 qui traversent de façon étanche la plaque mince supérieure 16. Chacun de ces tubes s'étend sur une certaine hauteur à l'intérieur du compartiment associé 13, et cette hauteur est déterminée en fonction de la charge qui est supportée par la structure au niveau du compartiment considéré. C'est en effet la hauteur du tube 17 à l'intérieur d'un compartiment 13 qui détermine la hauteur jusqu'à laquelle l'eau va pouvoir monter dans ce compartiment lorsque la structure est mise à l'eau. En effet, tant que le niveau de l'eau n'atteint pas l'extrémité inférieure du tube 17 dans un compartiment 13, l'air contenu dans ce compartiment peut s'échapper à l'extérieur par le tube 17. Quand l'eau atteint l'extrémité du tube 17, l'air contenu dans le compartiment 13 ne peut plus s'échapper à l'extérieur. L'eau continue cependant à monter très légèrement dans le compartiment, en raison de la compressibilité de l'air, et elle monte à l'intérieur du tube 17 jusqu'au niveau de la surface libre de l'eau autour de la structure 10, selon le principe des vases communicants.According to the present invention, the compartments 13 do not include a bottom, and the hydros- thrust is adjusted. static in each compartment, allowing water to penetrate to a certain height inside these compartments. This characteristic of the invention is shown schematically in Figure 3. In this figure, the structure 10 is shown floating on a body of water. The compartments 13a, 13c, 13d and 13e are shown provided with means making selectively communicate the interior of these compartments with the external atmosphere. These means consist of tubes 17 which pass tightly through the upper thin plate 16. Each of these tubes extends over a certain height inside the associated compartment 13, and this height is determined as a function of the load which is supported by the structure at the level of the compartment considered. It is in fact the height of the tube 17 inside a compartment 13 which determines the height to which the water will be able to rise in this compartment when the structure is launched. Indeed, as long as the water level does not reach the lower end of the tube 17 in a compartment 13, the air contained in this compartment can escape outside through the tube 17. When the water reaches the end of the tube 17, the air contained in the compartment 13 can no longer escape to the outside. However, the water continues to rise very slightly in the compartment, due to the compressibility of the air, and it rises inside the tube 17 to the level of the free surface of the water around the structure 10, according to the principle of communicating vessels.

On voit en figure 3 que le compartiment 13b est dépourvu de tube 17. Ce compartiment est celui au niveau duquel la charge supportée est la plus importante. Pour équilibrer cette charge, la poussée hydrostatique au niveau du compartiment 13b doit être maximum. L'eau pénètre donc dans ce compartiment uniquement en raison de la compressibilité de l'air qui y est enfermé Inversement, la structure 10 ne supporte aucune charge au niveau du compartiment 13e, et pour cette raison, le tube 17 associé s'étend à l'intérieur du compartiment 13e sur une hauteur correspondant au niveau de la surface libre extérieure de l'eau. La poussée hydrostatique est nulle au niveau du compartiment 13e.It can be seen in FIG. 3 that the compartment 13b has no tube 17. This compartment is the one at which the load supported is the greatest. To balance this load, the hydrostatic thrust at compartment 13b must be maximum. Water therefore enters this compartment only due to the compressibility of the air which is enclosed therein Conversely, the structure 10 does not support any load at the level of compartment 13e, and for this reason, the associated tube 17 extends to inside the compartment 13e over a height corresponding to the level of the free exterior surface of the water. The hydrostatic thrust is zero at the level of compartment 13e.

Les compartiments 13a, 13c et 13d correspondent à des emplacements où la charge supportée est à une valeur intermédiaire, les hauteurs sur lesquelles les tubes 17 s'étendent à l'intérieur de ces compartiments étant sensiblement proportionnelles à la charge supportée.The compartments 13a, 13c and 13d correspond to locations where the supported load is at an intermediate value, the heights over which the tubes 17 extend inside these compartments being substantially proportional to the supported load.

On comprend bien entendu que la représentation de la figure 3 est schématique et illustre uniquement le principe de l'invention. En effet, la structure 10 comprend un très grand nombre de compartiments 13, par exemple au nombre de 140 dans l'exemple représenté en figure 5, et dont la plupart doivent être pourvus d'un tube 17 réglé à une hauteur appropriée. La hauteur des tubes 17 est préalablement déterminée en fonction de la charge calculée supportée par la structure 10 au niveau des compartiments. Mais on a constaté qu'il n'était pas nécessaire de régler la hauteur des tubes 17 dans les compartiments 13 individuellement, et qu'il suffisait de grouper les compartiments en sous-ensembles dans chacun desquels la poussée hydrostatique est réglée à une valeur unique, c'est-à-dire que les tubes 17 des compartiments formant un même sous-ensemble sont réglés à la même hauteur, ces compartiments pouvant communiquer entre eux.It is understood of course that the representation of Figure 3 is schematic and illustrates only the principle of the invention. Indeed, the structure 10 includes a very large number of compartments 13, for example 140 in the example shown in Figure 5, and most of which must be provided with a tube 17 adjusted to an appropriate height. The height of the tubes 17 is determined beforehand as a function of the calculated load supported by the structure 10 at the level of the compartments. But we found that it was not necessary to adjust the height of the tubes 17 in the compartments 13 individually, and that it was sufficient to group the compartments into sub-assemblies in each of which the hydrostatic thrust is adjusted to a single value, that is to say to say that the tubes 17 of the compartments forming a same sub-assembly are adjusted to the same height, these compartments being able to communicate with each other.

La figure 5 représente un exemple de répartition des 140 compartiments en 13 sous-ensembles définis transversalement en I, II, III, IV et V et longitudinalement en A, B, C.. Le sous-ensemble II ne comprend pas de tubes plongeurs. Par contre, les compartiments 13 des sous-ensembles A, D et C des autres groupes I, III, IV et V sont tous équipés d'un tube plongeur. Dans chaque sous-ensemble, les tubes sont réglés à la même hauteur, et cette hauteur varie d'un sous-ensemble à l'autre en fonction de la charge supportée.FIG. 5 represents an example of distribution of the 140 compartments in 13 sub-assemblies defined transversely in I, II, III, IV and V and longitudinally in A, B, C .. The sub-assembly II does not include dip tubes. On the other hand, the compartments 13 of the sub-assemblies A, D and C of the other groups I, III, IV and V are all fitted with a dip tube. In each sub-assembly, the tubes are adjusted to the same height, and this height varies from one sub-assembly to another depending on the load supported.

On a représenté schématiquement en figure 4 un mode de fixation d'un tube plongeur 17 dans un compartiment 13.FIG. 4 schematically shows a method of fixing a dip tube 17 in a compartment 13.

L'extrémité supérieure du tube 17 est soudée sur la face supérieure de la plaque 16, comme indiqué en 18, et sous la plaque 16, le tube 17 est soudé en deux zones 19 sur une patte verticale 15 de raidissement solidaire d'une poutre 12.The upper end of the tube 17 is welded to the upper face of the plate 16, as indicated in 18, and under the plate 16, the tube 17 is welded in two zones 19 on a vertical tab 15 of stiffening secured to a beam 12.

Dans les figures 6 et 7, on a représenté schématiquement.deux modes de fixation des équipements industriels sur la structure 10.In FIGS. 6 and 7, two methods of fixing industrial equipment to the structure 10 are shown schematically.

Un équipement 11a, ayant un poids relativement peu important, est porté par deux berceaux 20 qui sont fixés directement sur .la face supérieure de la plaque mince 16, comme représenté en figure 6.Equipment 11a, having a relatively low weight, is carried by two cradles 20 which are fixed directly to the upper face of the thin plate 16, as shown in FIG. 6.

Un équipement 11b, ayant un poids plus important, est porté également par des berceaux 21 qui sont fixés sur des plaques ou semelles 22 de répartition de charge, elles-mêmes fixées sur la face supérieure de la plaque mince 16, avantageusement au niveau des poutres 12 ou de renforts appropriés. Quand la plaque mince 16 est en acier, la fixation se fait bien entendu par soudure.An equipment 11b, having a greater weight, is also carried by cradles 21 which are fixed on plates or plates 22 of load distribution, themselves fixed on the upper face of the thin plate 16, advantageously at the beams 12 or suitable reinforcements. When the thin plate 16 is made of steel, the fixing is of course done by welding.

La structure 10 peut être réalisée en tout matériau approprié..Dans un mode de réalisation préféré, elle sera réalisée en acier, mais elle peut également être réalisée en béton, en fibre de verre, ou en matériaux différents (une partie en béton, l'autre en acier),etc.The structure 10 can be made of any suitable material. In a preferred embodiment, it will be made of steel, but it can also be made of concrete, fiberglass, or different materials (one part in concrete, one other steel), etc.

Cette structure selon l'invention est mise en oeuvre de la façon suivante.This structure according to the invention is implemented in the following manner.

Elle est construite et assemblée en un endroit approprié, à terre, les équipements industriels 11 étant fixés à demeure sur la structure 10 par exemple de la façon décrite dans les figures 6 et 7. Les tubes 17 sont montés dans les compartiments 13, par exemple de la façon représentée en figure 4, en s'étendant dans chaque compartiment sur une hauteur appropriée fonction de la charge supportée au niveau du compartiment. La structure 10 portant les équipements 11 est ensuite mise à l'eau, dans un plan d'eau calme. Les poussées hydrostatiques différentes exercées au niveau des différents compartiments 13 ou des différents sous-ensembles de compartiments, permettent d'éviter des déformations verticales relatives importantes de la structure 10. Celle-ci est ensuite chargée sur un porte-barge semi-submersible, ou sur tout autre engin approprié de navigation, d'une façon connue en soi, et est transportée jusqu'au site d'utilisation, où elle est déchargée de sur le porte-barge ou engin,ou analogue dans un plan d'eau calme, avant d'être finalement échouée sur le site d'utilisation.It is constructed and assembled in a suitable place, on the ground, the industrial equipment 11 being permanently fixed to the structure 10 for example as described in FIGS. 6 and 7. The tubes 17 are mounted in the compartments 13, for example as shown in Figure 4, extending in each compartment to an appropriate height depending on the load supported at the compartment. The structure 10 carrying the equipment 11 is then launched into a calm body of water. The different hydrostatic thrusts exerted at the level of the various compartments 13 or of the various subsets of compartments make it possible to avoid significant relative vertical deformations of the structure 10. The latter is then loaded onto a semi-submersible barge carrier, or on any other suitable device required for navigation, in a manner known per se, and is transported to the site of use, where it is unloaded from on the barge or machine carrier, or the like in a body of calm water, before being eventually failed on the site of use.

La structure 10 est destinée par exemple à être enterrée, et à constituer les fondations dans le sol des équipements industriels 11 qu'elle supporte. Pour cela, les compartiments 13 sont avantageusement remplis de béton ou de tout autre matériau approprié. Ainsi, même si la structure 10 est soumise à une corrosion, sa détérioration ou sa disparition n'aura pas grande importance, le béton coulé dans les compartiments 13 constituant lui-même une fondation insensible à la corrosion.The structure 10 is intended for example to be buried, and to constitute the foundations in the ground of the industrial equipment 11 that it supports. For this, the compartments 13 are advantageously filled with concrete or any other suitable material. Thus, even if the structure 10 is subjected to corrosion, its deterioration or disappearance will not be of great importance, the concrete poured into the compartments 13 itself constituting a foundation insensitive to corrosion.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et représenté qui n'a été donné qu'à titre d'exemple. En particulier, elle comprend tous les moyens constituant des équivalents techniques des moyens décrits ainsi que leurs combinaisons, si celles-ci sont exécutées suivant son esprit et mises en oeuvre dans le cadre des revendications qui suivent.Of course, the invention is in no way limited to the embodiment described and shown which has been given only by way of example. In particular, it includes all the means constituting technical equivalents of the means described as well as their combinations, if these are carried out according to the spirit and implemented in the context of the claims which follow.
