Description

La présente invention se rapporte à un procédé de réalisation d'un châssis pour une construction, notamment un châssis plus particulièrement adapté à une construction susceptible de flotter telle que décrite dans la demande de brevet WO-03.03173 2 .The present invention relates to a method for producing a frame for a construction, in particular a frame more particularly adapted to a construction that can float as described in the patent application. WO-03.03173 2 .

La demande de brevet WO-03.031732 propose une construction susceptible de se déplacer entre une première position en appui au sol et une seconde position flottante. Selon ce document, le châssis de la construction est constitué de poutrelles en acier galvanisé ou en aluminium par exemple, formant un maillage apte à recevoir le plancher isolé d'une construction. Ce maillage est nécessaire pour assurer la reprise de la charge et pour conserver plan ce plancher.The patent application WO 03.031732 proposes a construction capable of moving between a first position in support of the ground and a second floating position. According to this document, the frame of the construction consists of galvanized steel beams or aluminum for example, forming a mesh capable of receiving the insulated floor of a building. This mesh is necessary to ensure the recovery of the load and to maintain plan this floor.

Le châssis comprend également des moyens de flottaison sous forme de caissons emprisonnés dans le maillage de la structure métallique formée par les poutrelles.The chassis also comprises flotation means in the form of boxes trapped in the mesh of the metal structure formed by the beams.

Même si ce mode de réalisation procure une assise convenable pour la construction, il ne donne pas pleinement satisfaction pour les raisons suivantes :

  • En premier lieu, la structure métallique doit être traitée pour pouvoir résister à la corrosion, notamment si elle est utilisée comme châssis pour une construction telle que décrite dans la demande de brevet WO-03.031732 . Ce traitement conduit nécessairement à augmenter le coût de la structure. De plus, compte tenu de l'usage, ce traitement de surface a tendance à s'abîmer rendant nécessaire un entretien périodique.
  • En second lieu, la réalisation par mécano-soudage de la structure induit un grand nombre d'heures de main d'oeuvre conduisant à un prix de revient de la structure élevé. Ce prix est d'autant plus élevé que le prix de l'acier est lui-même relativement élevé.
Although this embodiment provides a suitable foundation for the construction, it does not give full satisfaction for the following reasons:
  • First, the metal structure must be treated to be able to resist corrosion, especially if it is used as a frame for a construction as described in the patent application. WO 03.031732 . This treatment necessarily leads to increase the cost of the structure. In addition, given the use, this surface treatment tends to deteriorate making necessary periodic maintenance.
  • Second, the mechanical welding of the structure induces a large number of hours of labor leading to a cost of the high structure. This price is all the higher as the price of steel is itself relatively high.

Par ailleurs, l'insertion des moyens de flottaison sous forme de caissons à l'intérieur de la structure métallique en forme de maillage est relativement longue et complexe à réaliser conduisant à augmenter le prix de revient du châssis.Furthermore, the insertion of the caisson-type flotation means inside the mesh-shaped metal structure is relatively long and complex to achieve, leading to an increase in the cost price of the chassis.

Enfin, il est nécessaire d'assurer une liaison mécanique résistante entre les moyens de flottaison et la structure métallique rendant encore plus complexe et donc plus coûteux le procédé de réalisation d'une telle structure.Finally, it is necessary to ensure a strong mechanical connection between the flotation means and the metal structure making the process of producing such a structure even more complex and therefore more expensive.

Le document US 6 199 502 décrit un module pour construction susceptible de flotter, ainsi qu'une méthode de construction d'un tel module.The document US 6,199,502 describes a floatable construction module and a method of constructing such a module.

Aussi, la présente invention vise à pallier les inconvénients de l'art antérieur en proposant un procédé de réalisation d'un châssis pour une construction, notamment un châssis pour une construction susceptible de flotter telle que décrite dans la demande de brevet WO-03.031732 , ledit procédé étant simple à mettre en oeuvre, permettant de réduire les coûts de production et d'obtenir une structure résistante d'un point de vue mécanique.Also, the present invention aims at overcoming the drawbacks of the prior art by proposing a method of producing a chassis for a construction, in particular a chassis for a construction that can float as described in the patent application. WO 03.031732 , said method being simple to implement, to reduce production costs and to obtain a mechanically resistant structure.

A cet effet, l'invention a pour objet un procédé de réalisation d'un châssis pour une construction susceptible de flotter caractérisé en ce qu'il comprend les étapes consistant à :

  • former des moyens de flottaison dont la partie supérieure comprend un réseau de gorges susceptibles de former des coffrages pour des poutres en béton ainsi que des puits, traversant lesdits moyens de flottaison, susceptibles de former des coffrages pour des colonnes de béton,
  • de manière avantageuse, disposer des ferraillages dans les coffrages et ajouter en périphérie un coffrage pour former une ceinture, et
  • couler le béton.
To this end, the subject of the invention is a method for producing a chassis for a floatable construction, characterized in that it comprises the steps consisting of:
  • forming flotation means whose upper part comprises a network of grooves capable of forming forms for concrete girders as well as wells, passing through said flotation means, capable of forming forms for concrete columns,
  • advantageously, having reinforcement in the formwork and adding a formwork at the periphery to form a belt, and
  • pour concrete.

La présente invention propose également un châssis obtenu selon le procédé précité ainsi qu'un module utilisé pour élaborer ledit châssis.The present invention also proposes a chassis obtained according to the aforementioned method and a module used to develop said chassis.

Sur la figure 1, on a représenté en 10 un châssis sur lequel peut être rapportée une construction non représentée. Ce châssis 10 est plus particulièrement adapté aux constructions mobiles entre deux positions, une première en appui au sol et une seconde flottante, telles que décrites dans la demande de brevet WO-03.031732 . Toutefois, ce châssis peut être utilisé pour d'autres types de constructions nécessitant un châssis formant une fondation hors sol.On the figure 1 , there is shown in 10 a frame on which can be reported a not shown construction. This frame 10 is more particularly adapted to mobile constructions between two positions, a first ground support and a floating second, as described in the patent application. WO 03.031732 . However, this frame can be used for other types of constructions requiring a chassis forming an above ground foundation.

Selon l' invention, le châssis comprend des moyens 12 de flottaison dont la partie supérieure comprend un réseau de gorges susceptibles de former des coffrages pour des poutres 14 en béton ainsi que des puits, traversant lesdits moyens 12 de flottaison, susceptibles de former des coffrages pour des colonnes 16 de béton.According to the invention, the chassis comprises means 12 for flotation whose upper part comprises a network of grooves capable of forming forms for concrete beams 14 and wells, passing through said means 12 for flotation, capable of forming forms for columns 16 of concrete.

Cet agencement permet d'obtenir un châssis résistant grâce au réseau de poutres 14, susceptible de recevoir une dalle ou un plancher pour une construction, ledit châssis étant susceptible de résister aux efforts de compression produits par la construction grâce aux colonnes 16.This arrangement makes it possible to obtain a resistant frame thanks to the network of beams 14, capable of receiving a slab or a floor for a construction, said frame being able to withstand the compressive stresses produced by the construction thanks to the columns 16.

Comme illustré sur la figure 1, le réseau est constitué d'une première série de poutres de préférence équidistantes et d'une seconde série de poutres, de préférence équidistantes, perpendiculaires aux premières poutres.As illustrated on the figure 1 , the network consists of a first series of beams preferably equidistant and a second series of beams, preferably equidistant, perpendicular to the first beams.

La section des poutres, la distance séparant les poutres ainsi que leur nombre sont déterminés par l'homme du métier en fonction notamment de la charge susceptible d'être appliquée sur le châssis 10. De même, la section des colonnes, leur nombre et leurs emplacements sont déterminés par l' homme du métier afin que le châssis résiste aux efforts de compression.The section of the beams, the distance separating the beams and their number are determined by those skilled in the art depending in particular on the load likely to be applied to the frame 10. Similarly, the section of the columns, their number and their locations are determined by those skilled in the art so that the chassis resists compression efforts.

De préférence, les poutres 14 et les colonnes 16 comprennent un ferraillage afin d'accroître les propriétés mécaniques du châssis.Preferably, the beams 14 and the columns 16 comprise a reinforcement in order to increase the mechanical properties of the frame.

Avantageusement, les colonnes 16 sont disposées au niveau des intersections des poutres 14.Advantageously, the columns 16 are disposed at the intersections of the beams 14.

Selon une autre caractéristique de l'invention, les poutres 14 relient les colonnes 16 entre elles, et ont une face inférieure en forme d'arche, comme illustré sur les figures 2A et 2B, afin d'augmenter les propriétés mécaniques desdites poutres 14.According to another characteristic of the invention, the beams 14 connect the columns 16 to each other, and have an arch-shaped lower face, as illustrated in the drawings. Figures 2A and 2B in order to increase the mechanical properties of said beams 14.

De préférence, les pieds des colonnes 16 comprennent des moyens 20 d'amortissement, venant en saillie par rapport à la surface inférieure des moyens de flottaison 12. Selon un mode de réalisation, ces moyens 20 d'amortissement sont obtenus à partir d'un insert 22 en caoutchouc, comme illustré sur la figure 7, disposé en partie inférieure des puits dans lesquels sont coulées les colonnes. Chaque insert 22 comprend en partie supérieure une collerette susceptible de prendre appui contre un épaulement ménagé en partie inférieure des puits. Cet agencement permet d'accroître la résistance du châssis et de la construction en cas de séisme en désolidarisant le châssis et la construction du sol. Cet agencement permet de conférer au châssis des qualités parasismiques.Preferably, the legs of the columns 16 comprise damping means 20 protruding from the lower surface of the Flotation means 12. According to one embodiment, these damping means 20 are obtained from a rubber insert 22, as shown in FIG. figure 7 disposed in the lower part of the wells in which the columns are cast. Each insert 22 comprises in the upper part a collar capable of bearing against a shoulder formed in the lower part of the wells. This arrangement makes it possible to increase the strength of the frame and the construction in the event of an earthquake by separating the frame and the construction of the ground. This arrangement makes it possible to confer chassis seismic qualities.

Selon une autre caractéristique de l'invention, le châssis 10 comprend au niveau de sa partie supérieure, en périphérie, une ceinture 24 de béton armé susceptible de former un chaînage. Selon un mode de réalisation préféré, le châssis comprend en périphérie un coffrage 26 en forme de goulotte en U dont une première branche 28 est accolée aux moyens 12 de flottaison. Des tirants 30 sont avantageusement prévus pour relier les extrémités supérieures des branches de la goulotte en U afin d'éviter la déformation de ladite goulotte lors du coulage du béton. Les tirants 30 sont répartis tout autour de la ceinture. Selon les variantes, le coffrage 26 peut être relié directement aux moyens 12 de flottaison et/ou les tirants 30 peuvent être reliés par tous moyens appropriés, tels que par exemple par soudage, aux ferraillages prévus pour les poutres 14.According to another characteristic of the invention, the frame 10 comprises at its upper part, at the periphery, a belt 24 of reinforced concrete capable of forming a chaining. According to a preferred embodiment, the frame comprises at the periphery a formwork 26 in the form of a channel U with a first branch 28 is contiguous to the means 12 for flotation. Tie rods 30 are advantageously provided for connecting the upper ends of the branches of the U-shaped chute in order to prevent deformation of said chute during pouring of the concrete. The tie rods 30 are distributed around the waist. According to the variants, the formwork 26 can be connected directly to the floatation means 12 and / or the tie rods 30 can be connected by any appropriate means, such as, for example, by welding, to the reinforcement provided for the beams 14.

Selon une variante simplifiée de l'invention, le procédé de réalisation d'un châssis pour construction comprend les étapes suivantes consistant à :

  • former des moyens 12 de flottaison dont la partie supérieure comprend un réseau de gorges susceptibles de former des coffrages pour des poutres 14 en béton ainsi que des puits, traversant lesdits moyens 12 de flottaison, susceptibles de former des coffrages pour des colonnes 16 de béton,
  • de manière avantageuse, disposer des ferraillages dans les coffrages et ajouter en périphérie un coffrage pour former une ceinture, et
  • couler le béton.
According to a simplified variant of the invention, the method of producing a frame for construction comprises the following steps:
  • forming flotation means 12 whose upper part comprises a network of grooves capable of forming forms for concrete beams 14 and wells, passing through said flotation means 12, capable of forming forms for concrete columns 16,
  • advantageously, having reinforcement in the formwork and adding a formwork at the periphery to form a belt, and
  • pour concrete.

Après séchage du béton, le coffrage utilisé pour couler le béton forme les moyens de flottaison. Grâce au réseau de poutres liées aux puits, on obtient une liaison mécanique solide entre la partie béton et les moyens de flottaison. Cette liaison peut être renforcée par tout moyen, tel que par exemple en augmentant la rugosité de la surface des moyens de flottaison formant coffrage.After drying the concrete, the formwork used to pour the concrete forms the means of flotation. Thanks to the network of beams connected to the wells, a solid mechanical connection is obtained between the concrete part and the flotation means. This connection can be reinforced by any means, such as for example by increasing the roughness of the surface of the flotation means forming formwork.

Selon une première variante, le châssis 10 ne comprend qu'un réseau de poutres en partie supérieure comme illustré sur la figure 1. Selon une autre variante, le châssis 10 est recouvert par une dalle en béton comportant en partie inférieure les poutres 14 et les colonnes 16.According to a first variant, the frame 10 comprises only a network of beams in the upper part as shown in FIG. figure 1 . According to another variant, the frame 10 is covered by a concrete slab comprising in the lower part the beams 14 and the columns 16.

Selon un mode de réalisation préféré, les moyens 12 de flottaison sont réalisés par l'assemblage de plusieurs modules 32 tels qu'illustrés sur les figures 2B, 3 à 9, lesdits modules étant réalisés par moulage de matière plastique. Selon une variante simplifiée, les moyens de flottaison peuvent être réalisés d'un seul tenant comme illustré par la figure 2A.According to a preferred embodiment, the flotation means 12 are made by assembling a plurality of modules 32 as illustrated in FIGS. Figures 2B , 3 at 9, said modules being made by plastic molding. According to a simplified variant, the flotation means can be made in one piece as illustrated by the Figure 2A .

Selon un mode de réalisation, un module 32 de forme sensiblement parallélépipédique est réalisé par rotomoulage.According to one embodiment, a module 32 of substantially parallelepiped shape is made by rotational molding.

La hauteur des modules 32 est ajustée en fonction de la charge supportée par le châssis afin que ce dernier puisse notamment flotter. En variante, on peut empiler des couches de modules 32 afin d'augmenter les capacités de flottaison du châssis. A cet effet, la face supérieure du module a une forme adaptée susceptible de coopérer avec la face inférieure du module supérieur.The height of the modules 32 is adjusted according to the load supported by the chassis so that the latter can in particular float. Alternatively, layers of modules 32 may be stacked to increase the floatation capabilities of the chassis. For this purpose, the upper face of the module has a suitable shape capable of cooperating with the lower face of the upper module.

Chaque module 32 comprend au niveau de sa face supérieure deux gorges 34 et 36, susceptibles de former un coffrage pour les poutres 14, lesdites gorges 34 et 36 étant de préférence sensiblement perpendiculaires et en position de médiatrice lorsque le module a une forme carrée ou rectangulaire.Each module 32 comprises at its upper face two grooves 34 and 36, capable of forming a formwork for the beams 14, said grooves 34 and 36 preferably being substantially perpendicular and in a mediating position when the module has a square or rectangular shape .

En complément, le module comprend un puits 38 susceptible de former un coffrage pour une colonne 16. Avantageusement, le puits 38 est disposé à l'intersection des gorges 34 et 36.In addition, the module comprises a well 38 capable of forming a formwork for a column 16. Advantageously, the well 38 is disposed at the intersection of the grooves 34 and 36.

De préférence, le fond des gorges 34 et 36 est incurvé et incliné vers le puits 38 de manière à former des arches lorsque les modules sont assemblés comme illustré sur la figue 2B.Preferably, the bottom of the grooves 34 and 36 is curved and inclined towards the well 38 so as to form arches when the modules are assembled as shown in Fig 2B.

Selon une variante, le procédé de réalisation consiste à assembler des modules 32 de manière à former les moyens de flottaison 12 avec en partie supérieure un réseau de gorges susceptibles de former des coffrages pour des poutres 14 en béton ainsi que des puits, traversant lesdits moyens 12 de flottaison, susceptibles de former des coffrages pour des colonnes 16 de béton, comme illustré sur la figure 4.According to one variant, the production method consists of assembling modules 32 so as to form the flotation means 12 with, at the top, a network of grooves capable of forming forms for concrete beams 14 and wells passing through said means. 12 flotation capable of forming forms for concrete columns 16, as illustrated in figure 4 .

Lorsque les modules sont assemblés, on peut alors couler le béton, après avoir de préférence, ajouté le ferraillage dans les coffrages ainsi qu'éventuellement le coffrage formant la ceinture périphérique.When the modules are assembled, it is then possible to pour the concrete, after having preferably added the reinforcement in the formwork as well as possibly the formwork forming the peripheral belt.

Comme illustré sur les figures 3 et 5, les gorges 34 et 36 définissent en partie supérieure du module quatre secteurs 40 avec chacun des formes en saillie 42 susceptibles de coopérer avec des formes en creux ménagées sous la face inférieure d'un module supérieur. Avantageusement, pour des gains de productivité, tous les modules sont identiques quelle que soit la couche. Ainsi, un même module comprend une face supérieure avec des éléments en saillie 42 et une face inférieure avec des formes en creux dont les formes sont adaptées à celles des éléments en saillie 42.As illustrated on figures 3 and 5 , the grooves 34 and 36 define in the upper part of the module four sectors 40 with each of the projecting shapes 42 capable of cooperating with recessed shapes formed under the underside of an upper module. Advantageously, for productivity gains, all modules are identical regardless of the layer. Thus, the same module comprises an upper face with projecting elements 42 and a lower face with recessed shapes whose shapes are adapted to those of the projecting elements 42.

Selon une autre caractéristique, comme illustré sur la figure 6, chaque module comprend en partie inférieure au moins un évidement 44, de préférence quatre au niveau de chaque secteur 40. Ces évidements 44 renforcent la résistance à la compression du module.According to another characteristic, as illustrated on the figure 6 each module comprises in the lower part at least one recess 44, preferably four at each sector 40. These recesses 44 reinforce the compressive strength of the module.

De manière avantageuse, les parois latérales du module comportent également des évidements 45 permettant également de renforcer la résistance à la compression du module.Advantageously, the side walls of the module also include recesses 45 also to enhance the compressive strength of the module.

Selon une autre caractéristique de l'invention, le châssis comprend des moyens 46 d'assemblage permettant de relier les différents modules 32 préalablement au coulage du béton et lors du séchage. Ces moyens 46 d'assemblage comportent une tige 48 avec à chaque extrémité une griffe 50. La longueur de la tige est adaptée pour qu'une première griffe 50.1 soit disposée au dessous des modules et qu'une seconde griffe 50.2 soit disposée au dessus des modules, comme illustré sur la figure 8. En complément, au moins un écrou est prévu pour coopérer avec un filetage ménagé sur la tige afin de plaquer les griffes 50 contre les modules et d'enserrer lesdits modules afin de les maintenir assemblés avant de couler le béton. De préférence, comme illustré sur les figures 8 et 9, les griffes 50 ont des extrémités 52 courbes susceptibles éventuellement de coopérer avec des formes en creux ménagées au niveau des modules afin de mieux agripper lesdits modules.According to another characteristic of the invention, the chassis comprises assembly means 46 for connecting the different modules 32 prior to pouring the concrete and during drying. These assembly means 46 comprise a rod 48 with at each end a claw 50. The length of the rod is adapted so that a first claw 50.1 is disposed below the modules and a second claw 50.2 is disposed above the modules, as illustrated on the figure 8 . In addition, at least one nut is provided to cooperate with a thread formed on the rod in order to press the claws 50 against the modules and to grip said modules in order to keep them assembled before pouring the concrete. Preferably, as illustrated on the Figures 8 and 9 , the claws 50 have curved ends 52 that may cooperate with recessed shapes formed at the modules to better grip said modules.

Selon les variantes, lorsque le châssis comprend plusieurs couches de modules, les tiges 48 s'étendent sur toute la hauteur du châssis ou des moyens de connexion 53 sont prévus pour relier les tiges des différents niveaux, comme illustré sur la figure 9.According to the variants, when the chassis comprises several layers of modules, the rods 48 extend over the entire height of the chassis or connection means 53 are provided to connect the rods of the different levels, as shown in FIG. figure 9 .

Avantageusement, les tiges 48 sont disposées au niveau de la zone de connexion de quatre modules adjacents. A cet effet, les modules comprennent au niveau de chaque angle, un décrochement 54 en quart de rond s'étendant sur toute la hauteur des parois latérales, comme illustré sur la figure 5. Lorsque quatre modules sont assemblés les quatre décrochements 54 en quart de rond adjacents forment un conduit 56 susceptible de loger une tige 48, comme illustré sur la figure 4. Selon un autre mode de réalisation, en plus des décrochements 54 en quart de rond, chaque module comprend au niveau de chaque paroi latérale, deux décrochements 58 en demi rond décalés par rapport au sommet, s'étendant sur toute la hauteur des parois latérales, comme illustré sur la figure 4. Lorsque deux modules sont assemblés les décrochements 58 en demi rond forment un conduit 60 susceptible de loger une tige 48. Ces décrochements 58 facilitent l'assemblage des modules disposés en périphérie.Advantageously, the rods 48 are disposed at the connection zone of four adjacent modules. For this purpose, the modules comprise at each corner, a recess 54 in quarter round extending over the entire height of the side walls, as shown in FIG. figure 5 . When four modules are assembled, the four adjacent quarter-round recesses 54 form a duct 56 capable of housing a rod 48, as illustrated in FIG. figure 4 . According to another embodiment, in addition to the recesses 54 in quarter round, each module comprises at each side wall, two recesses 58 half round offset from the top, extending over the entire height of the side walls, as shown in the figure 4 . When two modules are assembled, the half-round recesses 58 form a duct 60 capable of housing a rod 48. These recesses 58 facilitate the assembly of the peripherally disposed modules.

Le procédé de réalisation d'un châssis est aisé et grandement simplifié. Il suffit d'assembler un nombre adéquat de modules 32 en fonction de la superficie et des formes souhaitées du châssis. Pour les maintenir assemblés, les tiges 48 et les griffes 50 sont mises en place. Si nécessaire une seconde couche voire plusieurs couches de modules sont ainsi assemblées.The method of making a chassis is easy and greatly simplified. It is sufficient to assemble an adequate number of modules 32 according to the desired area and shapes of the chassis. To keep them assembled, the rods 48 and the claws 50 are put in place. If necessary a second layer or several layers of modules are thus assembled.

Ainsi comme précédemment, on obtient au niveau de la couche supérieure un réseau de gorges susceptibles de former des coffrages pour des poutres 14 en béton ainsi que des puits, traversant lesdits moyens 12 de flottaison, susceptibles de former des coffrages pour de colonnes 16 de béton, comme illustré sur la figure 4. Les modules étant tous identiques et étant disposés l'un sur l'autre, les puits de chaque couche coopèrent permettant d'obtenir des coffrages pour les colonnes 16 s'étendant sur toute la hauteur du châssis.Thus, as above, at the level of the upper layer, an array of grooves capable of forming forms for concrete beams 14 and wells passing through said float means 12, capable of forming forms for concrete columns 16, is obtained. as shown on the figure 4 . The modules being all identical and being arranged one on the other, the wells of each layer cooperate to obtain formwork for the columns 16 extending over the entire height of the frame.

Lorsque les modules sont assemblés, on peut alors couler le béton, après avoir de préférence, ajouté le ferraillage dans les coffrages ainsi qu'éventuellement le coffrage formant la ceinture périphérique.When the modules are assembled, it is then possible to pour the concrete, after having preferably added the reinforcement in the formwork as well as possibly the formwork forming the peripheral belt.

Selon le procédé de l'invention, on obtient de manière économique un châssis susceptible de supporter une construction.According to the method of the invention, a chassis capable of supporting a construction is economically obtained.

En effet, les modules peuvent être réalisés de manière industrielle ce qui conduit à abaisser les coûts de fabrication. Ces modules peuvent être ensuite assemblés in situ de manière rapide. Différentes tailles et formes de châssis peuvent être obtenues en assemblant des modules identiques selon l'invention. En fonction de la charge à supporter, on peut augmenter les caractéristiques du châssis en assemblant une ou plusieurs couches de modules.Indeed, the modules can be made industrially which leads to lower manufacturing costs. These modules can then be assembled in situ quickly. Different sizes and frame shapes can be obtained by assembling identical modules according to the invention. Depending on the load to be supported, one can increase the characteristics of the chassis by assembling one or more layers of modules.

En suivant, il suffit de couler le béton. Après séchage, on obtient directement le châssis.By following, just pour the concrete. After drying, the frame is obtained directly.

Comme indiqué précédemment, le châssis obtenu à partir de l'invention permet d'obtenir un châssis flottant susceptible de supporter une construction afin d'obtenir une construction flottante. Toutefois, le présent châssis pourrait être utilisé dans d'autres applications, notamment lorsqu'on souhaite obtenir une fondation hors sol, désolidarisée du sol, tel que par exemple pour une construction parasismique.As indicated above, the chassis obtained from the invention makes it possible to obtain a floating chassis capable of supporting a construction in order to obtain a floating construction. However, the present chassis could be used in other applications, especially when it is desired to obtain a foundation above ground, detached from the ground, such as for example for a seismic construction.

Avantageusement, le châssis 12 est destiné à une construction telle que décrite dans la demande de brevet WO-03.031732 .Advantageously, the frame 12 is intended for a construction as described in the patent application WO 03.031732 .

Dans ce cas, le châssis comprend au moins un conduit 62 traversant le châssis sur sa hauteur, pour permettre le passage d'un pieu le long duquel peut coulisser le châssis lorsque le niveau de l'eau monte et que le châssis 12 flotte.In this case, the frame comprises at least one duct 62 passing through the frame over its height, to allow the passage of a pile along which can slide the frame when the water level rises and the frame 12 floats.

De préférence, le châssis comprend plusieurs conduits 62 susceptibles de loger des pieux le long desquels peut coulisser le châssis 12.Preferably, the chassis comprises several ducts 62 capable of housing piles along which the chassis 12 can slide.

Selon un mode de réalisation, chaque conduit 62 est ménagé dans un module 64. Avantageusement, ce module 64 comprend des moyens 66 de renfort de préférence métallique, délimitant le conduit 62, susceptibles de renforcer le module et de limiter la déformation dudit conduit 62. De préférence, les moyens 66 de renfort sont reliés au réseau de poutres 14. Ainsi, ils peuvent être noyés au moins en partie dans le réseau de poutres en béton ou reliés aux ferraillages utilisés pour le réseau de poutres 14.According to one embodiment, each duct 62 is formed in a module 64. Advantageously, this module 64 comprises preferably metallic reinforcement means 66 delimiting the duct 62, capable of reinforcing the module and limiting the deformation of said duct 62. Preferably, the reinforcing means 66 are connected to the network of beams 14. Thus, they may be embedded at least in part in the network of concrete beams or connected to the reinforcement used for the network of beams 14.

Selon un mode de réalisation préféré et illustré sur la figure 10, le ou les module(s) 64 sont obtenus chacun à partir de deux demi-modules 64.1 et 64.2 symétriques selon un plan vertical médian 68. Dans ce cas, les moyens 66 de renfort sont réalisés en deux parties, une partie pour chaque demi-module 64.1 et 64.2. Selon un mode de réalisation, les demi-modules sont réalisés par moulage, les moyens 66 de renfort formant des inserts intégrés dans le moule et partiellement noyés dans la matière moulée.According to a preferred embodiment and illustrated on the figure 10 the module (s) 64 are each obtained from two half-modules 64.1 and 64.2 symmetrical in a median vertical plane 68. In this case, the reinforcement means 66 are made in two parts, one part for each half -module 64.1 and 64.2. According to one embodiment, the half-modules are made by molding, the reinforcing means 66 forming inserts integrated into the mold and partially embedded in the molded material.

Les moyens 66 de renfort comprennent pour chaque demi module un berceau 70 avec une section selon un plan vertical en forme de U, ledit berceau 70 étant obtenu par l'assemblage mécano soudé de profilés. Ainsi chaque, berceau comprend deux U, l'un disposé au niveau du plan supérieur du module et l'autre disposé au niveau du plan inférieur du module, des traverses reliant les U au niveau des extrémités des branches du U et de part et d'autre de la base du U, comme illustré sur les figures 11 et 12.The reinforcement means 66 comprise, for each half-module, a cradle 70 with a section along a U-shaped vertical plane, said cradle 70 being obtained by the mechanically welded assembly of profiles. Thus, each cradle comprises two U, one disposed at the level of the upper plane of the module and the other disposed at the lower plane of the module, cross members connecting the U at the ends of the branches of the U and of part and other of the base of the U, as shown in Figures 11 and 12 .

Lorsque les demi-modules sont disposés l'un contre l'autre les berceaux 70 sont disposés en vis-à-vis et forment un conduit 62 comme illustré sur la figure 10.When the half-modules are placed against each other the cradles 70 are arranged vis-a-vis and form a conduit 62 as shown in FIG. figure 10 .

Pour améliorer les caractéristiques mécaniques, les moyens 66 de renfort comprennent pour chaque demi-module un berceau en U et des jambages 72 etTo improve the mechanical characteristics, the reinforcing means 66 comprise for each half-module a U-shaped cradle and jambs 72 and

les demi-modules comprennent des gorges 74 dans le prolongement des gorges des modules adjacents, lesdits jambages étant disposés au niveau desdites gorges 74. Cet agencement permet de relier les moyens 66 de renfort au réseau de poutres 14. Selon un mode de réalisation préféré et illustré par les figures 10 et 12, un premier jambage 72 est prévu s'étendant perpendiculairement à la base du U du berceau 70 dans un plan sensiblement vertical, les autres jambages 72 s'étendant perpendiculairement aux branches du U à partir de leurs extrémités dans un plan vertical.the half-modules comprise grooves 74 in the extension of the grooves of the adjacent modules, said legs being arranged at said grooves 74. This arrangement makes it possible to connect the reinforcing means 66 to the network of beams 14. According to a preferred embodiment and illustrated by the Figures 10 and 12 , a first leg 72 is provided extending perpendicularly to the base of the U of the cradle 70 in a substantially vertical plane, the other legs 72 extending perpendicularly to the branches of the U from their ends in a vertical plane.

Comme précédemment, les demi-modules sont réalisés de préférence par rotomoulage.As before, the half-modules are preferably made by rotational molding.

Ils sont assemblés in situ aux autres modules 32 grâce aux moyens 46 d'assemblage. Une fois assemblés, les modules forment les moyens de flottaison 12 avec au niveau de la face supérieure un réseau de gorges susceptibles de former des coffrages pour des poutres 14 en béton ainsi que des puits, traversant lesdits moyens 12 de flottaison, susceptibles de former des coffrages pour des colonnes 16 de béton.They are assembled in situ to the other modules 32 by means 46 of assembly. Once assembled, the modules form the flotation means 12 with at the level of the upper face a network of grooves capable of forming forms for concrete beams 14 and wells, passing through said floating means 12, capable of forming forms for columns 16 of concrete.

Lorsque les modules sont assemblés, on peut alors couler le béton, après avoir de préférence, ajouté le ferraillage dans les coffrages ainsi qu'éventuellement le coffrage formant la ceinture périphérique.When the modules are assembled, it is then possible to pour the concrete, after having preferably added the reinforcement in the formwork as well as possibly the formwork forming the peripheral belt.

Selon ce mode de réalisation, une partie des jambages 72 est noyée dans le réseau de poutres 14 ce qui contribue à améliorer les propriétés mécaniques du châssis obtenu.According to this embodiment, part of the jambs 72 is embedded in the network of beams 14 which contributes to improving the mechanical properties of the frame obtained.

Bien entendu, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne les dimensions et les matériaux des différents éléments formant le châssis. Enfin, d'autres matériaux pourraient être utilisés à la place du béton pour être coulés dans les gorges et les puits et assurer la résistance mécanique au châssis.Of course, the invention is obviously not limited to the embodiment shown and described above, but covers all variants, especially with regard to the dimensions and materials of the various elements forming the frame. Finally, other materials could be used instead of concrete to be poured into the grooves and wells and ensure the mechanical strength to the chassis.
