Description

La présente invention est relative aux dispositifs d'ancrage pour fixer des câbles de structure à des éléments de construction.The present invention relates to the devices anchor for fixing structural cables to elements of construction.

En particulier, l'invention est appliquée chaque fois qu'il est nécessaire de fixer un câble soumis à des efforts de traction, pour équiper des éléments de construction tels que des ponts haubanés, suspendus ou autres, en reliant les sommets des pylônes de ces ponts à leurs tabliers et à leurs massifs d'ancrage.In particular, the invention is applied each it is necessary to fix a cable subject to tensile forces, to equip elements of such as cable-stayed bridges, suspended or others, by connecting the tops of the pylons of these bridges to their aprons and their anchor beds.

Les câbles habituellement rencontrés dans de tels éléments de construction comprennent une pluralité de brins qui comportent chacun des fils métalliques eux-mêmes enveloppés ensemble dans une gaine de protection, chacune de ces gaines de protection étant interrompue au niveau d'une tranche terminale de sorte que les brins possèdent chacun un tronçon d'extrémité dénudé.The cables usually encountered in such construction elements include a plurality of strands which each include wires themselves wrapped together in a protective sheath, each of these protective sheaths being interrupted at a level of terminal slice so that the strands each have a bare end section.

Les dispositifs d'ancrage habituellement rencontrés, et notamment dans le EP-A-0 323 285 comprennent :

  • un bloc perforé sur lequel sont ancrés individuellement les tronçons d'extrémité dénudés des différents brins,
  • une portée qui est solidaire de l'élément de construction et contre laquelle est en appui axial le pourtour du bloc perforé,
  • un tube auquel est raccordé le bloc perforé du côté de la portée, le tube délimitant transversalement une chambre à l'intérieur de laquelle sont situées les tranches terminales des brins et qui est remplie d'une matière assurant la protection des tronçons d'extrémité dénudés présents dans la chambre, et
  • un presse-étoupe qui ferme de façon étanche la chambre, à l'opposé du bloc d'ancrage, et qui est traversé de manière étanche par les brins gainés, le presse-étoupe comprenant :
    • au moins deux plaques perforées dont l'une dite intérieure est disposée du côté de la chambre et l'autre dite extérieure est disposée à l'opposé du bloc perforé par rapport à la plaque intérieure, et
    • au moins un coussin d'étoupe qui est interposé entre les plaques intérieure et extérieure.
The anchoring devices usually encountered, and in particular in EP-A-0 323 285, include:
  • a perforated block on which are individually anchored the stripped end portions of the different strands,
  • a bearing which is integral with the construction element and against which is axially supported the periphery of the perforated block,
  • a tube to which is connected the perforated block on the bearing side, the tube transversely delimiting a chamber inside which are located the end slices of the strands and which is filled with a material ensuring the protection of the bare end sections present in the room, and
  • a stuffing box which sealingly closes the chamber, opposite the anchor block, and is sealed through the sheathed strands, the stuffing box comprising:
    • at least two perforated plates, one of which is said to be internal on the side of the chamber and the other of which is said to be outside the perforated block with respect to the inner plate, and
    • at least one packing cushion which is interposed between the inner and outer plates.

Dans les modes de réalisation connus des presse-étoupe rencontrés dans les dispositifs d'ancrage du genre en question, la plaque intérieure du presse-étoupe est fixe tandis que la plaque extérieure est mobile et est entraínée vers la plaque fixe au moyen de tiges filetées traversant le bloc perforé et mises en traction. Ces tiges sont à la fois vissées dans la plaque extérieure et dans un écrou en butée contre le bloc perforé.In the known embodiments of the cable glands encountered in anchoring devices of the kind in question, the inner plate of the cable gland is fixed while the outer plate is movable and is driven to the fixed plate by means of threaded rods running through the perforated block and put in traction. These stems are both screwed into the outer plate and into an abutment nut against the perforated block.

Afin d'assurer une bonne étanchéité du dispositif d'ancrage, il est possible de comprimer à nouveau le coussin du presse-étoupe en exerçant une traction sur la plaque extérieure si cela s'avère nécessaire. Toutefois, les extrémités des tiges filetées vissées dans la plaque extérieure sont situées du côté des câbles et ne sont donc pas accessibles à l'opérateur sans démonter l'ensemble du dispositif d'ancrage.To ensure a good seal of the device anchoring it is possible to compress the cushion again of the cable gland by pulling on the plate outside if necessary. However, ends of the threaded rods screwed into the plate are located on the cable side and are therefore not not accessible to the operator without dismantling the entire anchoring device.

Un tel dispositif d'ancrage nécessite donc des opérations de maintenance importantes et coûteuses puisque les parties mécaniquement sollicitées sont situées dans des endroits difficilement accessibles. Such an anchoring device therefore requires important and costly maintenance operations since mechanically solicited parts are located in hard to reach places.

La présente invention a pour but de remédier aux inconvénients précités en fournissant un dispositif d'ancrage facilitant les opérations de maintenance.The present invention aims to remedy aforementioned drawbacks by providing a device Anchoring makes maintenance easier.

A cet effet, selon l'invention, un dispositif d'ancrage du genre en question est caractérisé en ce que la plaque extérieure est fixe par rapport à la chambre et en ce que le dispositif comprend des moyens d'appui sur la plaque intérieure.For this purpose, according to the invention, a device anchor of the kind in question is characterized in that the outer plate is fixed by to the chamber and in that the device includes support means on the inner plate.

Ainsi, grâce à ces dispositions, tous les éléments constitutifs du presse-étoupe sont protégés contre la corrosion et les éléments qui permettent de mettre en compression le coussin d'étoupe sont accessibles depuis le côté du dispositif d'ancrage opposé au côté à partir duquel s'étendent les câbles et n'impliquent donc pas de démontage coûteux.Thus, thanks to these provisions, all the elements components of the cable gland are protected against corrosion and the elements that make it possible to compression the gland cushion are accessible since the side of the anchoring device opposite the side from which extend the cables and therefore do not involve disassembly expensive.

Dans des modes de réalisation préférés du dispositif d'ancrage selon la présente invention, on a recours en outre à l'une et/ou à l'autre des dispositions suivantes :

  • les moyens d'appui sur la plaque intérieure comportent une tige de compression dont une extrémité est en butée sur la plaque intérieure et dont l'autre extrémité traverse un trou ménagé dans le bloc perforé et est actionnable depuis le côté du bloc perforé qui est opposé à la portée solidaire de l'élément de construction ;
  • la tige de compression est une tige filetée et le trou est taraudé, la tige étant actionnable par vissage;
  • la tige de compression est en butée contre une plaque d'interposition montée adjacente à la plaque intérieure ;
  • les moyens d'appui comprennent une butée qui est solidaire du tube et qui est située à l'intérieur du tube à une distance de la face extérieure de la plaque extérieure sensiblement égale à l'épaisseur du presse-étoupe et dans lequel ledit au moins un coussin d'étoupe est perforé par des passages de diamètre inférieur au diamètre des brins gainés ;
  • le presse-étoupe est placé dans une gorge ménagée à l'intérieur du tube et la butée est définie par le ressaut entre la gorge et la partie courante du tube ;
  • la plaque extérieure est en butée contre un manchon d'arrêt rapporté par vissage à l'extrémité du tube ;
  • la plaque extérieure est en butée contre une plaque perforée rapportée à l'extrémité du tube ;
       la matière de protection est en compression dans la chambre ; et
  • un capot est monté de manière étanche sur le bloc perforé, délimitant une chambre dans laquelle font saillie les tronçons d'extrémité dénudés des brins, la chambre étant remplie de ladite matière de protection.
In preferred embodiments of the anchoring device according to the present invention, one or more of the following provisions are also used:
  • the support means on the inner plate comprise a compression rod, one end of which is abutting on the inner plate and the other end of which passes through a hole formed in the perforated block and is operable from the side of the perforated block which is opposite. within the integral scope of the construction element;
  • the compression rod is a threaded rod and the hole is tapped, the rod being operable by screwing;
  • the compression rod is in abutment with an interposing plate mounted adjacent to the inner plate;
  • the support means comprise a stop which is integral with the tube and which is located inside the tube at a distance from the outer face of the outer plate substantially equal to the thickness of the gland and in which said at least a packing bag is perforated by passages of diameter less than the diameter of the sheathed strands;
  • the gland is placed in a groove inside the tube and the stop is defined by the projection between the groove and the current part of the tube;
  • the outer plate is in abutment against a stop sleeve reported by screwing at the end of the tube;

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 a suspension bridge whose cables are immobilized by anchoring devices according to the present invention;
  • Figure 2 is a cross-sectional view of a cable of Figure 1;
  • Figure 3 is an enlarged sectional view of one of the strands constituting the cable of Figure 2;
  • Figure 4 is a longitudinal sectional view of a first embodiment of the anchoring device of the cable of Figures 2 and 3;
  • Figure 5 is a longitudinal sectional view of a second embodiment of the anchoring device for fixing the cable of Figures 2 and 3; and
  • FIG. 6 is an enlarged sectional view of the gland of the anchoring device of FIG. 5.

L'élément de construction 1 représenté à la figure 1 est par exemple un pont suspendu. Ce pont comporte classiquement un tablier 2, deux piliers ou pylônes 3, deux câbles porteurs parallèles 4, un seul étant visible sur la figure, et une pluralité de suspentes 4a qui sont accrochées aux câbles 4 et qui portent le tablier 2.The construction element 1 shown in FIG. is for example a suspension bridge. This bridge comprises conventionally an apron 2, two pillars or pylons 3, two parallel carrying cables 4, only one being visible on the figure, and a plurality of hangers 4a that are hooked to the cables 4 and which carry the apron 2.

Les câbles porteurs 4 sont tendus entre deux massifs d'ancrage au sol 9 situés aux deux extrémités du pont, et ils sont soutenus par les deux pylônes 3.The carrying cables 4 are stretched between two beds ground anchor 9 located at both ends of the bridge, and they are supported by the two pylons 3.

Comme le montre plus particulièrement la figure 2, le câble 4 considéré est composé d'une pluralité de brins individuels 5.As shown more particularly in Figure 2, the cable 4 considered is composed of a plurality of strands individual 5.

Chaque brin 5 est lui-même formé, comme le montre la figure 3, d'une pluralité de fils élémentaires 6, par exemple au nombre de sept. Ces fils peuvent être parallèles ou torsadés et sont par exemple réalisés en acier galvanisé ou galfanisé. L'ensemble de ces fils est entouré par une gaine de protection 7 qui est apte à protéger ceux-ci au cours de toute leur vie contre la corrosion due aux intempéries ou autre agression extérieure, et notamment à l'humidité et aux manutentions. Cette gaine est par exemple réalisée en une matière plastique, telle que le polyéthylène ou une polyamide, ou en un métal tel que l'aluminium ou l'acier inoxydable. La gaine est directement rapportée sur le faisceau de fils par extrusion. Each strand 5 is itself formed, as shown in FIG. FIG. 3, of a plurality of elementary wires 6, by example to the number of seven. These wires can be parallel or twisted and are for example made of galvanized steel or galfanized. All of these threads are surrounded by a protective sheath 7 which is able to protect them at life course against corrosion due to bad weather or other external aggression, and in particular humidity and handling. This sheath is for example made of a plastic material, such as polyethylene or a polyamide, or a metal such as aluminum or stainless steel. The sheath is directly reported on the wire bundle by extrusion.

La gaine en question peut également être constituée par tout autre revêtement désirable du faisceau de fils 6, par exemple par une peinture époxy enduite sur celui-ci.The sheath in question may also be constituted by any other desirable coating of the wire bundle 6, for example by an epoxy paint coated on it.

Les intervalles compris entre les fils 6 et la gaine 7, s'ils existent, peuvent être comblés ou non par une substance protectrice 8 telle que, par exemple, un brai résineux de type époxy ou une cire ou polybutadiène.The intervals between the wires 6 and the sheath 7, if they exist, can be filled or not by a protective substance 8 such as, for example, a pitch resinous epoxy type or a wax or polybutadiene.

Les brins gainés 5 ainsi définis, sont tous identiques entre eux, sont autonomes et le demeurent pendant toute la durée de la vie du câble 4 qu'ils constituent.The sheathed strands 5 thus defined, are all identical to each other, are autonomous and remain so for the entire life of the cable 4 they constitute.

Les brins gainés 5 du câble 4 sont mis en tension individuellement, de manière connue en soi, sur le pont 1. Par exemple, le montage est assuré à l'aide de manchons filés ou encore, comme représenté aux figures 4 et 5, par serrage des extrémités des brins 5 dans des mors fendus 10.The sheathed strands 5 of the cable 4 are put in tension individually, in a manner known per se, on the bridge 1. For example, the assembly is ensured by means of sleeves spun or, as shown in FIGS. 4 and 5, by tightening the ends of the strands 5 in split jaws 10.

Pour cela, chacune des gaines de protection 7 des brins 5 est interrompue au niveau d'une tranche terminale T de sorte que chaque brin 5 possède un tronçon d'extrémité 11 dénudé.For this, each of the protective sheaths 7 of the strands 5 is interrupted at a terminal slice T so that each strand 5 has an end portion 11 bare.

Les tronçons d'extrémité dénudés 11 sont serrés dans les mors fendus 10 qui présentent chacun d'une part, un trou cylindrique taraudé propre à entourer jointivement l'extrémité du brin à ancrer et d'autre part, une surface extérieure tronconique propre à coopérer avec un logement complémentaire ménagé dans un bloc d'ancrage perforé 15.The denuded end sections 11 are tight in the split jaws 10 which each have, on the one hand, a hole cylindrical threaded clean to surround contiguously the end of the strand to anchor and secondly, a surface outer frustoconical clean to cooperate with housing complementary formed in a perforated anchor block 15.

Chaque brin 5 est ainsi mis en tension entre par exemple, un pilier 3 du pont 1 et le bloc perforé 15 solidaire, par exemple, de l'un des massifs d'ancrage 9 de ce pont.Each strand 5 is thus tensioned between for example, a pillar 3 of the bridge 1 and the perforated block 15 solidary, for example, of one of the anchoring beds 9 of this bridge.

Le bloc perforé 15 possède deux faces opposées : une face extérieure 16 et une face intérieure 17. La face extérieure 16 est tournée à l'opposé des brins 5. Les extrémités 12 des tronçons d'extrémité 11 font saillie sur cette face. La face intérieure 17 est tournée du côté des brins 5.The perforated block 15 has two opposite faces: a outer face 16 and an inner face 17. The face 16 is turned away from the strands 5. ends 12 of the end sections 11 protrude from this face. The inner face 17 is turned towards the strands 5.

Afin de protéger les tronçons d'extrémité 11 des brins 5 contre la corrosion, les tranches terminales T de chacun de ces brins sont situées à l'intérieur d'une chambre 20 délimitée :

  • à une première extrémité axiale, par la face intérieure 17 du bloc perforé 15,
  • transversalement, par un tube rigide 22 qui est par exemple de forme cylindrique à base circulaire et qui est vissé ou soudé à l'une de ses extrémités pour être réglable ou fixe par rapport à la face intérieure 17 du bloc perforé 15 ;
  • et à l'extrémité axiale opposée au bloc 15, par un presse-étoupe 25 qui est traversé de façon étanche par les brins gainés 5 et qui est pressé de façon étanche contre la face intérieure 23 du tube 22 sous l'effet d'une compression axiale.
In order to protect the end sections 11 of the strands 5 against corrosion, the end slices T of each of these strands are located inside a delimited chamber 20:
  • at a first axial end, by the inner face 17 of the perforated block 15,
  • transversely, by a rigid tube 22 which is for example cylindrical in shape with a circular base and which is screwed or welded at one of its ends to be adjustable or fixed relative to the inner face 17 of the perforated block 15;
  • and at the axial end opposite the block 15, by a stuffing box 25 which is penetrated in a sealed manner by the sheathed strands 5 and which is pressed sealingly against the inner face 23 of the tube 22 under the effect of a axial compression.

Le presse-étoupe 25 est constitué, de manière connue en soi, de trois plaques perforées 26, 27 et 28 entre lesquelles sont interposés deux coussins 29 et 30 réalisés en matériau élastomère ou analogue.The gland 25 is constituted, in a known manner in itself, three perforated plates 26, 27 and 28 between which are interposed two cushions 29 and 30 made of elastomeric material or the like.

Les plaques perforées 26 à 28 sont des plaques rigides en matériau plastique et l'ensemble des plaques et des coussins s'étend transversalement aux brins 5 pour être traversé par ceux-ci. La plaque 26 est une plaque extérieure située au niveau de l'extrémité du tube 22 tournée vers la partie courante du câble c'est-à-dire, du côté à partir duquel les brins 5 s'étendent en direction du pylône 3. Cette plaque est maintenue en position fixe par rapport à la chambre 20 en étant en butée contre un retour 32 ménagé à l'extrémité du tube 22.Perforated plates 26 to 28 are plates rigid plastic material and the set of plates and cushions extends transversely to the strands 5 to be crossed by them. The plate 26 is an outer plate located at the end of the tube 22 turned towards the current part of the cable that is to say, from the side from which the strands 5 extend towards the pylon 3. This plate is held in a fixed position relative to the chamber 20 abutting against a return 32 formed to the end of the tube 22.

Les plaques 26 à 28 maintiennent les coussins 29,30 en compression pour faire gonfler les bords des coussins et assurer l'étanchéité désirée. A cet effet, des moyens d'appui 35 coopèrent avec la plaque 28 la plus proche de la chambre 20, encore appelée plaque intérieure.The plates 26 to 28 hold the cushions 29,30 in compression to inflate the edges of the cushions and ensure the desired sealing. For this purpose, means 35 cooperate with the plate 28 closest to the room 20, also called inner plate.

Dans le premier mode de réalisation représenté à la figure 4, les moyens d'appui 35 consistent en une plaque d'interposition 36 qui est perforée et qui est appliquée contre la plaque intérieure 28 et en des tiges filetées 37 (une seule étant représentée sur la figure 4). Les tiges filetées prennent la forme de vis chacune munie d'une tête 38.In the first embodiment shown in 4, the support means 35 consist of a plate interposition 36 which is perforated and which is applied against the inner plate 28 and threaded rods 37 (only one being shown in Figure 4). The stems threaded take the form of screws each provided with a head 38.

Une première extrémité de la tige filetée ou vis 37 est en appui contre la plaque d'interposition 36 tandis que la deuxième extrémité de la tige 37 traverse un trou taraudé ménagé dans le bloc perforé 15, de sorte que la tête 38 fasse saillie sur la face extérieure 16 de ce bloc. La tige filetée 37 est actionnable au moyen de la tête 38 pour être vissée au travers de le trou taraudé.A first end of the threaded rod or screw 37 is resting against the interposition plate 36 while the second end of the rod 37 passes through a threaded hole formed in the perforated block 15, so that the head 38 protrudes on the outer face 16 of this block. The stem threaded 37 is operable by means of the head 38 to be screwed through the threaded hole.

La plaque intermédiaire 36 est repoussée par vissage des tiges filetées ou vis 37. Au cours de cette compression, la plaque d'interposition 36 déplace la plaque intérieure 28 en la rapprochant de la plaque extérieure 26 qui, elle, reste fixe.The intermediate plate 36 is pushed back by screwing Threaded rods or screws 37. During this compression, the interposition plate 36 moves the inner plate 28 by bringing it closer to the outer plate 26 which, she remains fixed.

Afin d'immobiliser le bloc perforé 15 par rapport au massif d'ancrage 9, un tube de réglage 40 est monté solidaire de la face extérieure du tube 22, au voisinage de l'extrémité de ce tube adjacente au bloc perforé 15 tandis qu'une bague 41 est rapportée par vissage sur un filetage complémentaire ménagé sur le tube de réglage 40. Cette bague est en appui axial contre une portée annulaire 42 faisant partie du massif d'ancrage 9. Le tube de réglage 40 est par exemple soudé ou vissé sur le tube 22 tandis que le bloc perforé 15 est vissé sur le tube de réglage au moyen de vis 43 accessibles depuis la face extérieure 16 de ce bloc.In order to immobilize the perforated block 15 with respect to solid anchor 9, an adjustment tube 40 is mounted secured to the outer face of the tube 22, in the vicinity of the end of this tube adjacent to the perforated block 15 while that a ring 41 is attached by screwing on a thread complemented on the adjustment tube 40. This ring is in axial support against an annular bearing surface 42 part of the anchoring mass 9. The adjustment tube 40 is example welded or screwed on the tube 22 while the block perforated 15 is screwed on the adjustment tube by means of screws 43 accessible from the outer face 16 of this block.

Par ailleurs, un capot 45 est monté de manière étanche sur la face extérieure 16 du bloc perforé 15 et est maintenu sur celui-ci au moyen de vis 46. Ce capot délimite une chambre 47 dans laquelle sont situées les extrémités 12 des tronçons d'extrémité dénudés 11 des brins 5 et qui contient une matière de protection souple contre la corrosion de ces extrémités.Furthermore, a hood 45 is mounted so sealed on the outer face 16 of the perforated block 15 and is held on it by means of screws 46. This hood defines a chamber 47 in which are located the ends 12 stripped end sections 11 of the strands 5 and which contains a flexible protective material against corrosion of these ends.

La chambre 47 est remplie en matière de protection contre la corrosion au travers d'un orifice qui est ensuite fermé par un bouchon 48. La chambre 47 communique avec la chambre 20 par des passages ménagés dans le bloc perforé 15 (non représentés).Chamber 47 is filled with protection against corrosion through an orifice which is then closed by a plug 48. The chamber 47 communicates with the chamber 20 by passages in the perforated block 15 (not shown)

Après avoir mis en tension les brins 5 et avoir exercé une compression sur la plaque d'interposition 36 avec les tiges filetées ou vis 37, l'ensemble des deux chambres 20 et 47 est rempli avec la matière protégeant contre la corrosion les tronçons dénudés des brins 5.After straining the strands 5 and having exerted a compression on the interposition plate 36 with the threaded rods or screws 37, all of the two chambers 20 and 47 is filled with the material protecting against corrosion stripped sections of strands 5.

Grâce à ce montage, chaque brin 5 est autonome sur toute sa longueur et peut être tendu ou détendu indépendamment de ses voisins. Les extrémités 12 de ces brins sont facilement accessibles depuis la face extérieure 16 du bloc perforé 15.With this arrangement, each strand 5 is autonomous on all its length and can be stretched or relaxed regardless of its neighbors. The 12 ends of these strands are easily accessible from the outside 16 of the perforated block 15.

De même, les coussins 29 et 30 peuvent être périodiquement facilement remis en compression pour maintenir une bonne étanchéité grâce au vissage des têtes 38 des vis qui sont facilement accessibles depuis la face extérieure 16 du bloc 15. L'opérateur n'a pas à démonter certaines pièces constitutives du dispositif d'ancrage décrit précédemment pour accéder à des pièces masquées.Similarly, the cushions 29 and 30 can be periodically easily put back into compression for maintain a good seal thanks to the screwing of the heads 38 screws that are easily accessible from the face 16 of the block 15. The operator does not have to disassemble certain constituent parts of the anchoring device previously described to access hidden parts.

Le deuxième mode de réalisation représenté aux figures 5 et 6 diffère du précédent mode de réalisation uniquement par la forme des moyens d'appui 35, du diamètre des passages ménagés dans les coussins 29 et 30, et de l'extrémité du tube opposée au bloc d'ancrage.The second embodiment shown in Figures 5 and 6 differs from the previous embodiment only by the shape of the support means 35, the diameter passages in the cushions 29 and 30, and the end of the tube opposite to the anchor block.

Les brins 5 sont insérés dans les coussins 29 et 30 au travers de passages 50 qui ont un diamètre légèrement inférieur à celui de la gaine 7 des brins 5. De plus, une gorge 51 est ménagée à l'extrémité du tube 22 qui est opposée au bloc d'ancrage 15. Le tube 22 possède ainsi à son extrémité un tronçon de diamètre intérieur qui est supérieur au diamètre intérieur du reste du tube. Un ressaut 52 est défini par ce changement de diamètre. Les trois plaques perforées 26 à 28 et les coussins 29 et 30 sont insérés dans cette gorge 51 par l'extrémité du tube 22. Les plaques et les coussins sont en butée contre le ressaut 52 et sont maintenus en compression les uns contre les autres au moyen d'un manchon d'arrêt 53. Ce manchon est rapporté à l'extrémité du tube 22 et est maintenu au moyen d'un filetage 54 qui coopère avec un taraudage ménagé à l'intérieur de la portion d'extrémité du tube.The strands 5 are inserted into the cushions 29 and 30 through passages 50 which have a diameter slightly less than that of the sheath 7 of the strands 5. In addition, a 51 is formed at the end of the tube 22 which is opposite to the anchoring block 15. The tube 22 thus has its end a segment of inner diameter that is greater to the inside diameter of the rest of the tube. A jump 52 is defined by this change of diameter. The three plates perforated 26 to 28 and the cushions 29 and 30 are inserted in this groove 51 by the end of the tube 22. The plates and the cushions abut against the projection 52 and are held in compression against each other by means of a stop sleeve 53. This sleeve is referred to the end of the tube 22 and is maintained by means of a thread 54 which cooperates with a tapped thread to inside the end portion of the tube.

En variante, une plaque perforée remplace le manchon d'arrêt et est vissée à l'extrémité du tube 22. Cette plaque contient autant de perforations que de brins à insérer dans le presse-étoupe.Alternatively, a perforated plate replaces the sleeve stop and is screwed to the end of the tube 22. This plate contains as many perforations as strands to insert into the cable gland.

Lorsque les brins 5 sont insérés dans le presse-étoupe, la matière supplémentaire des coussins 29 et 30 due au diamètre réduit des passages 50 est comprimée contre la gorge 51, ce qui assure une très bonne étanchéité. When the strands 5 are inserted into the gland, the extra material of the cushions 29 and 30 due the reduced diameter of the passages 50 is compressed against the groove 51, which ensures a very good seal.

L'étanchéité est encore améliorée lorsque des inserts sont rapportés et insérés dans le presse-étoupe de sorte que la matière des coussins en encore plus repoussée. A cet effet, la plaque perforée est munie de perforations en nombre supérieur au nombre de brins.Sealing is further improved when inserts are reported and inserted into the cable gland of so that the material cushions even more repelled. For this purpose, the perforated plate is provided with perforations in number greater than the number of strands.

Dans encore une autre variante, la matière de la chambre 20 est mise en compression de sorte que la plaque intérieure 25 du presse-étoupe est repoussée en direction de la plaque extérieure qui elle, reste fixe. Les coussins 29, 30 sont ainsi comprimés plus fortement, renforçant l'étanchéité.In yet another variant, the material of the chamber 20 is put in compression so the plate inside the stuffing box is pushed back towards the outer plate which remains fixed. The cushions 29, 30 are thus compressed more strongly, strengthening sealing.
