D'autres caractéristiques et avantages de l'invention apparaítront au cours de la description détaillée suivante de deux de ses formes de réalisation, données à titre d'exemples non limitatifs, en regard des dessins annexés sur lesquels :

  • la figure 6 est une vue en coupe longitudinale du système de la figure 5.
Other features and advantages of the invention will become apparent from the following detailed description of two of its embodiments, given by way of non-limiting examples, with reference to the accompanying drawings, in which:
  • Figure 1 is a general schematic view of an offshore platform comprising cables anchored by connection systems according to the present invention;
  • Fig. 2 is a perspective view of a first embodiment of one of the connection systems of Fig. 1 according to the present invention;
  • Figure 3 is an exploded perspective view of the only plates of the system of Figure 2;
  • Figure 4 is a longitudinal sectional view of the system of Figure 2;
  • Fig. 5 is a perspective view of a second embodiment of one of the connection systems of Fig. 1 according to the present invention; and
  • FIG. 6 is a longitudinal sectional view of the system of FIG. 5.

La structure d'ouvrage de construction 1 représentée à la figure 1 et dans laquelle sont intégrés plusieurs systèmes de connexion selon la présente invention, prend par exemple la forme d'une plate-forme offshore. Cette plate-forme comporte classiquement une partie supérieure 2 qui est généralement située au dessus du niveau de la mer et qui est ancrée dans le fond 3 de la mer par des séries 4, 5 de câbles 6.The structure of construction work 1 represented in Figure 1 and in which are integrated several connection systems according to the present invention, takes by example the form of an offshore platform. This platform classically comprises an upper part 2 which is generally above sea level and which is anchored in the bottom 3 of the sea by series 4, 5 of cables 6.

Chaque câble est tendu entre un élément constitutif 7 de la plate-forme 1, par exemple à des poutres de la partie supérieure 2, et un massif d'ancrage situé au fond 3 de la mer au moyen de systèmes de connexion 10 qui vont être décrits ci-après. Chaque câble est soumis à des efforts de traction importants tout en étant très résistants à la fatigue et à la corrosion.Each cable is stretched between a constituent element 7 of the platform 1, for example to the beams of the upper part 2, and an anchor at the bottom 3 of the sea by means of connection systems 10 that are going to be described below. Each cable is subject to traction while being very resistant to fatigue and corrosion.

Chaque câble 6 est constitué, de manière connue en soi, d'un faisceau de plusieurs brins qui sont eux-mêmes réalisés à partir d'une série de fils élémentaires 9. Le lecteur appréciera dans la suite que chaque câble peut être réduit à un brin ou même à un fil élémentaire.Each cable 6 is constituted in a manner known in self, of a bundle of several strands that are themselves made from a series of elementary threads. reader will appreciate in the following that each cable can be reduced to a strand or even an elementary wire.

Comme cela est plus particulièrement visible sur les figures 2 et 4, chaque brin est constitué d'un ensemble de fils 9 qui sont par exemple parallèles entre eux au niveau de leurs extrémités. Le brin ainsi formé peut être réuni à d'autres brins pour former le câble 6.As this is particularly visible on Figures 2 and 4, each strand consists of a set of son 9 which are for example parallel to each other at the level from their ends. The strand thus formed can be joined to other strands to form the cable 6.

Chaque fil 9 est réalisé en matériau métallique ou en matériau composite composé de fibres unidirectionnelles noyées dans une matrice de résine. Les fibres unidirectionnelles sont de préférence en carbone et peuvent être des fibres à haute résistance ou des fibres à haut module qui sont noyées dans une matrice époxyde réticulée, obtenue par exemple par un procédé de pultrusion.Each wire 9 is made of metallic material or made of composite material composed of unidirectional fibers embedded in a resin matrix. Fibers unidirectional are preferably carbon and can be high strength fibers or high fibers module that are embedded in a crosslinked epoxide matrix, obtained for example by a pultrusion process.

Avantageusement, les fils 9 sont de forme cylindrique à base circulaire et sont des fils pleins. Ils peuvent être également de tout autre profil, tel qu'un profil carré ou hexagonal.Advantageously, the threads 9 are of shape cylindrical with circular base and are solid wires. They can also be of any other profile, such as a square or hexagonal profile.

Le système de connexion 10 selon la présente invention comprend un dispositif de serrage 11 qui est lié à l'élément de structure 7 et un dispositif de transmission d'efforts 12. Ce dispositif de transmission est soumis aux forces de serrage exercées uniformément par le dispositif de serrage 11 et transmet ces forces aux fils 9 du brin qui sont ainsi fermement serrés.The connection system 10 according to the present invention comprises a clamping device 11 which is connected to the structural element 7 and a transmission device 12. This transmission device is subject to the clamping forces exerted uniformly by the tightening 11 and transmits these forces to the wires 9 of the strand which are thus firmly tightened.

Le dispositif de transmission 12 consiste, dans le premier mode réalisation, en un certain nombre de plaques 15 entre lesquelles sont logés les fils 9.The transmission device 12 consists, in the first embodiment, in a number of plates 15 between which are housed the threads 9.

Chacune des plaques 15 est sensiblement de forme rectangulaire et possède une face supérieure 16, une face inférieure 17 sensiblement plane et des bords longitudinaux 18, pris suivant l'épaisseur de la plaque, de forme courbe de manière à ce que l'ensemble des plaquettes 15, une fois superposées les unes aux autres, forment un cylindre à base circulaire. Ainsi, chaque plaquette 15 constitue en quelque sorte une tranche longitudinale d'un cylindre qui est de faible épaisseur par rapport à sa longueur.Each of the plates 15 is substantially shaped rectangular and has an upper face 16, one face substantially flat bottom 17 and longitudinal edges 18, taken according to the thickness of the plate, of curved form so that all platelets 15, once superimposed on each other, form a base cylinder circular. Thus, each wafer 15 constitutes in so a longitudinal slice of a cylinder that is of thin compared to its length.

Chacune des faces supérieure 16 et inférieure 17 des plaquettes 15 possède un canal 20. La section transversale des canaux 20 est voisine de la demi-section transversale des fils 9.Each of the upper faces 16 and lower 17 of the pads 15 has a channel 20. The cross section channels 20 is close to the cross sectional half wires 9.

Les canaux 20 d'une face supérieure 16 d'une plaquette 15 sont en regard des canaux 20 d'une face inférieure 17 de la plaquette 15 suivante. Les canaux 20 définissent ainsi deux à deux des passages 21 dont la section transversale est complémentaire de celle des fils 9.The channels 20 of an upper face 16 of a plate 15 are facing the channels 20 of a face lower 17 of the next wafer. The channels 20 thus define two by two passages 21 whose cross-section is complementary to that of the wires 9.

Les plaquettes 15 sont réalisées en matériau métallique ou en matériau composite ou organique. The pads 15 are made of material metal or composite or organic material.

Le dispositif de serrage 11 est constitué d'un mors 25 et de moyens 26 qui prennent ici la forme d'un fourreau pour mettre en compression le mors 25.The clamping device 11 consists of a jaw 25 and means 26 which here take the form of a sheath to compress the bit 25.

Le mors 25 possède plusieurs clavettes 27. L'ensemble des clavettes 27 définissent un cylindre à base annulaire possédant une extrémité proximale 28 et une extrémité distale 29. Le diamètre intérieur de ce cylindre est proche du diamètre de l'empilement cylindrique des plaquettes 15. L'épaisseur de la paroi au niveau de l'extrémité proximale 28 est supérieure à l'épaisseur de la paroi au niveau de l'extrémité distale 29. L'extrémité proximale est l'extrémité sur laquelle font saillie les extrémités des fils 9 tandis que l'extrémité distale est celle à partir de laquelle s'étendent les fils en direction du reste de l'ouvrage de construction.The jaw 25 has several keys 27. The set of keys 27 define a cylinder based ring having a proximal end 28 and a distal end 29. The inner diameter of this cylinder is close to the diameter of the cylindrical stack of The thickness of the wall at the level of the proximal end 28 is greater than the thickness of the wall at the distal end 29. The end proximal is the end on which the ends of the wires 9 while the distal end is the one from which the wires extend in the direction from the rest of the construction work.

Ainsi, chaque clavette 27 possède une face intérieure 30 en appui sur les plaquettes 15 et une face extérieure 31 convergente en direction de la face intérieure 30.Thus, each key 27 has a face 30 inside bearing on the pads 15 and one face outer 31 converges towards the inner face 30.

Le fourreau 26 est un cylindre à base annulaire dont la paroi intérieure 32 est de forme complémentaire de celle de la paroi extérieure du cylindre défini par les clavettes 27. Ainsi, le manchon 26 possède une première extrémité ou extrémité distale 33 dont l'ouverture est de diamètre inférieur à l'ouverture de la deuxième extrémité ou extrémité proximale 34 de ce manchon.The sheath 26 is a cylinder with an annular base the inner wall 32 is of complementary shape to that the outer wall of the cylinder defined by the keys 27. Thus, the sleeve 26 has a first end or distal end 33 whose opening is of diameter less than the opening of the second end or proximal end 34 of this sleeve.

Par conséquent, la paroi intérieure 32 du fourreau est de forme tronconique et est complémentaire de la forme extérieure, elle-même tronconique, du cylindre défini par l'ensemble des clavettes 27. Le diamètre de l'ouverture de l'extrémité 33 est légèrement supérieur au diamètre du cylindre défini par l'empilement des plaquettes 15. Therefore, the inner wall 32 of the sheath is frustoconical in shape and is complementary to the shape exterior, itself frustoconical, of the cylinder defined by the set of keyways 27. The diameter of the opening of the end 33 is slightly larger than the diameter of the cylinder defined by stacking platelets 15.

Pour réaliser le système de connexion 10 précédemment décrit, de la colle est appliquée dans chacun des canaux 20 des plaquettes 15, puis les fils 9 sont mis en place dans ces canaux et les plaquettes 15 sont empilées les unes sur les autres. L'empilement ainsi réalisé est alors inséré dans les clavettes 27. L'ensemble est ensuite enfilé dans le fourreau 26 par l'extrémité proximale 34, dont l'ouverture est de grand diamètre. Les clavettes 27 sont mises en compression par effet de coin entre leur surface extérieure et la face intérieure du fourreau 26 de sorte qu'une force de serrage prédéterminée est appliquée sur les plaquettes 15 et est transmise aux fils 9. Il suffit ensuite de procéder au séchage de la colle.To realize the connection system 10 previously described, glue is applied in each channels 20 of the plates 15, then the wires 9 are set place in these channels and the pads 15 are stacked the on each other. The stack thus produced is then inserted into the keys 27. The assembly is then threaded in the sheath 26 by the proximal end 34, of which the opening is of large diameter. The keys 27 are put in compression by corner effect between their surface outer and the inner face of the sleeve 26 so that a predetermined clamping force is applied to the platelets 15 and is transmitted to the son 9. Then it suffices to proceed to the drying of the glue.

La force de serrage prédéterminée sur les fils 9 est fonction de la pente de chacune des faces inclinées des clavettes et du fourreau et de la force avec laquelle les clavettes 27 sont insérées dans le fourreau 26.The predetermined clamping force on the wires 9 is function of the slope of each of the inclined faces of keys and sheath and the force with which the keys 27 are inserted into the sheath 26.

Ainsi, chaque fil 9 d'un brin est fermement ancré pour résister par exemple à des forces de traction.Thus, each wire 9 of a strand is firmly anchored to resist, for example, tensile forces.

Dans le mode de réalisation précédemment décrit, les plaquettes 15 du dispositif de transmission d'efforts occupent tout le volume intérieur du cylindre défini par les clavettes 27.In the embodiment previously described, the plates 15 of the force transmission device occupy the entire interior volume of the cylinder defined by the keys 27.

Dans le deuxième mode de réalisation représenté aux figures 5 et 6, le système de connexion 50 ne diffère de celui précédemment décrit que par la forme du dispositif de transmission d'efforts 52, les autres éléments constitutifs sont semblables et portent des références numériques identiques.In the second embodiment shown in Figures 5 and 6, the connection system 50 differs from that previously described only by the shape of the device of transmission of effort 52, the other constituent elements are similar and carry numerical references identical.

Le dispositif de transmission 52 n'occupe plus tout le volume intérieur du cylindre défini par les clavettes 27 du mors 25. Ce dispositif consiste en une pluralité de manchons métalliques 55 par exemple réalisés en aluminium. Les manchons 55 sont de diamètre intérieur sensiblement identique au diamètre des fils 9 de manière à emmancher de force ces fils dans les manchons. Le diamètre extérieur des manchons est faible par rapport au diamètre intérieur du cylindre délimité par les clavettes 27.The transmission device 52 no longer occupies any the interior volume of the cylinder defined by the keys 27 of the jaws 25. This device consists of a plurality of metal sleeves 55 for example made of aluminum. The sleeves 55 are of substantially internal diameter identical to the diameter of the wires 9 so as to forces these wires into the sleeves. The outside diameter of sleeves is small compared to the inner diameter of the cylinder delimited by the keys 27.

Les fils 9 sont en outre collés à l'intérieur des manchons 55. Ces manchons sont réalisés en matériau à limite élastique basse, possédant une certaine plasticité.The threads 9 are furthermore glued inside the 55. These sleeves are made of boundary material low elastic, with a certain plasticity.

Le montage du système de connexion 50 est sensiblement identique au montage du système du premier mode de réalisation. Les manchons 55 sont tangents les uns aux autres à l'intérieur des clavettes, chacun des manchons 55 étant en contact avec les manchons adjacents ou une clavette selon trois génératrices. En fait, lors du serrage, les manchons sont légèrement écrasés de sorte que chaque manchon est en contact suivant trois surfaces. Seule une partie d'entre eux, les manchons périphériques, sont en contact avec les clavettes.The mounting of the connection system 50 is substantially identical to the assembly of the first mode system of realization. The sleeves 55 are tangent to each other other inside the keys, each sleeve 55 being in contact with adjacent sleeves or a key according to three generators. In fact, when tightening, the sleeves are slightly crushed so that each sleeve is in contact along three surfaces. Only a part of them, the peripheral sleeves, are in contact with the keys.

En variante, les manchons peuvent être collés entre eux en comblant les interstices existant entre les manchons.Alternatively, the sleeves can be glued between they fill in the gaps between the sleeves.

Dans encore une autre variante, les manchons 55 sont en section transversale, de forme extérieure non circulaire mais voisine d'un losange ou autre de manière à juxtaposer aisément les manchons.In yet another variant, the sleeves 55 are in cross-section, of non-circular outer shape but close to a rhombus or other so as to juxtapose easily the sleeves.
