Description

La présente invention concerne le domaine des dispositifs d'étanchéité pour des conduits verticaux de traversée de parois de bâtiments telles que des toitures ou des toitures-terrasses.The present invention relates to the field of sealing devices for vertical ducts passing through walls of buildings such as roofs or flat roofs.

Actuellement, les conduits de traversée qui débordent au-dessus de la paroi sont rendus étanches par le fait que l'étanchéité du dessus de la toiture est prolongée vers le haut autour et contre les conduits, cette étanchéité étant en outre ramenée à l'intérieur de la partie supérieure des conduits. Du fait que les conduits de traversée sont cylindriques et que l'étanchéité doive faire un pli à 90 degrés au pied du conduit et un pli à 180 degrés en haut du conduit, une telle manière de faire est compliquée et requiert une attention particulière. Elle est en conséquence onéreuse et des risques de malfaçons sont possibles, voire inévitables.At present, the crossing ducts which project above the wall are rendered watertight by the fact that the watertightness of the top of the roof is extended upwards around and against the ducts, this sealing being further brought back inside. from the upper part of the ducts. Because the bushings are cylindrical and the seal should bend 90 degrees at the foot of the conduit and a 180 degree fold at the top of the conduit, such a procedure is complicated and requires special attention. It is consequently expensive and risks of defects are possible, even unavoidable.

Le document DE 297 04 756 décrit un montage d'étanchéité dans lequel un tube extérieur est relié à une étanchéité du toit et est solidaire d'un tube intérieur de façon à aménager un espace annulaire à l'intérieur duquel est engagée l'extrémité annulaire supérieure d'un tube de traversée, plus ou moins en fonction de la position relative finale de montage du tube extérieur par rapport au conduit de traversée lors de la mise en place de l'étanchéité.The document DE 297 04 756 discloses a sealing assembly in which an outer tube is connected to a roof seal and is integral with an inner tube so as to provide an annular space within which is engaged the upper annular end of a tube of crossing, more or less depending on the final relative position of mounting of the outer tube relative to the passage duct during the implementation of the seal.

Le tube peut être muni à son extrémité inférieure d'une collerette annulaire destinée à être intégrée dans une étanchéité aménagée sur ladite paroi.The tube may be provided at its lower end with an annular collar intended to be integrated into a seal provided on said wall.

Il est également proposé une paroi d'un bâtiment, telle qu'une toiture ou une toiture-terrasse, munie d'un conduit de traversée présentant une partie d'extrémité supérieure s'étendant à l'extérieur et équipée d'un dispositif d'étanchéité tel que proposé ci-dessus.It is also proposed a wall of a building, such as a roof or a roof terrace, provided with a conduit for crossing having an upper end portion extending to the outside and provided with a sealing device as proposed above.

Un dispositif d'étanchéité selon un mode de réalisation de la présente invention va maintenant être décrit à titre d'exemple non limitatif et illustré par le dessin sur lequel :

  • la figure 1 représente une coupe verticale d'un dispositif d'aération installé sur une dalle de toit d'un bâtiment ; et
  • la figure 2 représente une coupe verticale agrandie d'une partie du dispositif d'étanchéité.
A sealing device according to an embodiment of the present invention will now be described by way of nonlimiting example and illustrated by the drawing in which:
  • the figure 1 represents a vertical section of a ventilation device installed on a roof slab of a building; and
  • the figure 2 represents an enlarged vertical section of a portion of the sealing device.

Sur la figure 1 est représentée une paroi 1 d'un bâtiment, telle qu'une toiture ou une toiture-terrasse, en particulier une dalle, sur laquelle sont posés un isolant 2 et une étanchéité supérieure 3. Cette paroi 1 est équipée d'un conduit cylindrique de traversée 4 installé verticalement dans un trou 5 de la paroi 1 et qui traverse l'isolant 2 et l'étanchéité supérieure 3, de telle sorte que le conduit 4 présente une partie d'extrémité supérieure qui s'étend à l'extérieur.On the figure 1 is represented a wall 1 of a building, such as a roof or a roof terrace, in particular a slab, on which are placed an insulator 2 and an upper seal 3. This wall 1 is equipped with a cylindrical duct of passage 4 installed vertically in a hole 5 of the wall 1 and which passes through the insulator 2 and the upper seal 3, so that the conduit 4 has an upper end portion which extends to the outside.

Un dispositif d'étanchéité 6 comprend un tube cylindrique 7 disposé verticalement, avec un jeu, autour du conduit 4. L'extrémité inférieure du tube 7 est fixée à la paroi 1. Selon un exemple, l'extrémité inférieure du tube 7 porte une collerette annulaire 8 intégrée à des couches de l'étanchéité 3. Selon un autre exemple, l'extrémité inférieure du tube 7 peut être munie d'une membrane souple, selon le brevet européen N° 1 710 365 , intégrée dans l'étanchéité 3.A sealing device 6 comprises a cylindrical tube 7 arranged vertically, with a clearance, around the conduit 4. The lower end of the tube 7 is fixed to the wall 1. In one example, the lower end of the tube 7 carries a In another example, the lower end of the tube 7 may be provided with a flexible membrane, according to the patent. European No 1 710 365 , integrated in the seal 3.

Le tube 7 présente une longueur telle qu'il s'étend vers le haut au-delà de l'extrémité supérieure du conduit 4.The tube 7 has a length such that it extends upwards beyond the upper end of the duct 4.

Le dispositif d'étanchéité 6 comprend en outre une bague intérieure 9 disposée à l'intérieur du tube 7 et apte à coulisser dans ce dernier.The sealing device 6 further comprises an inner ring 9 disposed inside the tube 7 and slidable therein.

Selon l'exemple de réalisation illustré plus précisément sur la figure 2, la bague 9 comprend successivement, de haut en bas, une partie annulaire supérieure de guidage 10 apte à coulisser à l'intérieur du tube 7, une partie annulaire intermédiaire d'appui 11 et une partie inférieure annulaire 13 apte à pénétrer à l'intérieur du conduit de traversée 4.According to the embodiment illustrated more precisely on the figure 2 , the ring 9 comprises successively, from top to bottom, an upper annular guide portion 10 adapted to slide inside the tube 7, an annular intermediate bearing part 11 and a part annular bottom 13 adapted to penetrate inside the passage duct 4.

La partie supérieure de guidage 10 permet de guider la bague intérieure 9 à l'intérieur du conduit de traversée 4, avec un faible jeu ou avec frottement. La partie supérieure de guidage 10 peut être substantiellement cylindrique.The upper guide portion 10 guides the inner ring 9 inside the passage duct 4, with little play or friction. The upper guide portion 10 may be substantially cylindrical.

Selon un mode de réalisation particulier, la partie supérieure de guidage 10 peut être en forme de tronc de cône ouvert vers le haut, à faible angle de conicité, par exemple inférieur à dix degrés, et dimensionnée de telle sorte que son bord supérieur soit en contact avec la face intérieure du tube 7, tout en permettant un coulissement.According to a particular embodiment, the upper guide portion 10 may be in the form of an upwardly conical truncated cone with a small conical angle, for example less than ten degrees, and dimensioned so that its upper edge is contact with the inner face of the tube 7, while allowing sliding.

Selon un autre mode de réalisation, la partie supérieure de guidage 10 pourrait être cylindrique et présenter des déformations radiales en contact avec la face intérieure du tube 7 et engendrant un frottement.According to another embodiment, the upper guiding portion 10 could be cylindrical and have radial deformations in contact with the inner face of the tube 7 and causing friction.

Selon un autre mode de réalisation, la partie supérieure de guidage 10 pourrait être cylindrique et son bord supérieur pourrait être évasé ou présenter des déformations radiales, pour être en contact avec la face intérieure du tube 7 et engendrer un frottement.According to another embodiment, the upper guiding portion 10 could be cylindrical and its upper edge could be flared or have radial deformations, to be in contact with the inner face of the tube 7 and generate friction.

Selon un autre mode de réalisation, la partie annulaire d'appui 11 peut être en forme de tronc de cône ouvert vers le haut, au moins en partie, par exemple à grand angle de conicité, en particulier compris entre trente et soixante degrés. La partie annulaire d'appui 11 est munie sur sa face inférieure d'un joint annulaire 12.According to another embodiment, the annular support portion 11 may be in the form of a truncated cone open upwards, at least in part, for example at a large cone angle, in particular between thirty and sixty degrees. The annular support portion 11 is provided on its underside with an annular seal 12.

Selon un autre mode de réalisation, la partie inférieure annulaire 13, qui est optionnelle, peut être par exemple cylindrique.According to another embodiment, the annular lower portion 13, which is optional, may for example be cylindrical.

Pour la mise en place du dispositif 1, on peut procéder de la manière suivante.For the establishment of the device 1, one can proceed as follows.

On installe le tube 7 sur la paroi 1 en reliant son extrémité inférieure à l'étanchéité 3.The tube 7 is installed on the wall 1 by connecting its lower end to the seal 3.

On engage la bague 9 dans le tube 7 par l'extrémité supérieure de ce dernier, à moins qu'elle ait été engagée préalablement. Dans ce dernier cas, le tube 7 peut être muni ou peut présenter des portions en saillie à ses extrémités pour maintenir la bague intérieure 9 à l'intérieur du tube 7, lors du transport et des manipulations,The ring 9 is engaged in the tube 7 by the upper end of the latter, unless it has been previously engaged. In the latter case, the tube 7 may be provided with or may have portions in projecting at its ends to hold the inner ring 9 inside the tube 7 during transport and handling,

Puis, on fait coulisser la bague intérieure 9 à l'intérieur du tube 7, qui est guidée par sa partie supérieure de guidage 10, jusqu'à ce que le joint annulaire 12 porté par la partie annulaire d'appui 11 vienne en appui ou s'écraser sur le bord supérieur du conduit 4 et en appui ou s'écraser contre la face intérieure du tube 7. Le joint d'étanchéité 12 a alors atteint sa position finale.Then, the inner ring 9 is slid inside the tube 7, which is guided by its upper guide portion 10, until the annular seal 12 carried by the annular support portion 11 comes to bear or crashing on the upper edge of the duct 4 and bearing or crashing against the inner face of the tube 7. The seal 12 has then reached its final position.

Dans le cas où la partie supérieure de guidage 10 frotte contre la paroi intérieure du tube 7, on exerce une poussée axiale de haut en bas sur la bague intérieure 9 à l'encontre de ce frottement. Lorsque le joint d'étanchéité a atteint sa position finale, on cesse la poussée. Après relâchement, la bague intérieure 9 est maintenue dans sa position atteinte grâce au contact de la partie annulaire supérieure 10 contre la face intérieure du tube 7 grâce au contact ferme entre le bord supérieur. Le joint annulaire 12 est alors maintenu dans sa position finale atteinte grâce à l'appui de la partie annulaire 11 de la bague intérieure 9.In the case where the upper guide portion 10 rubs against the inner wall of the tube 7, it exerts an axial thrust from top to bottom on the inner ring 9 against this friction. When the seal has reached its final position, the thrust is stopped. After loosening, the inner ring 9 is held in its position reached by contact of the upper annular portion 10 against the inner face of the tube 7 through the firm contact between the upper edge. The annular seal 12 is then held in its final position reached thanks to the support of the annular portion 11 of the inner ring 9.

Dans la position atteinte, la partie inférieure 13 de la bague 9 est engagée à l'intérieur et à distance du conduit de traversée 4.In the position reached, the lower part 13 of the ring 9 is engaged inside and at a distance from the passage duct 4.

Après quoi, on peut installer un chapeau 14 à distance de l'extrémité supérieure du tube 7, ce chapeau 14 étant muni de pattes 15 dont les extrémités inférieures sont reliées à l'extrémité supérieure du tube 7 par exemple par des agrafes 16.After which, it is possible to install a cap 14 at a distance from the upper end of the tube 7, this cap 14 being provided with tabs 15, the lower ends of which are connected to the upper end of the tube 7, for example by staples 16.

Il résulte de ce qui précède que si un liquide tel que de l'eau de pluie, de la poussière ou de la neige pénètre dans le tube 7, ces matières sont déviées par la bague intérieur 9 vers l'intérieur du conduit 4.It follows from the above that if a liquid such as rainwater, dust or snow enters the tube 7, these materials are deflected by the inner ring 9 towards the inside of the duct 4.

Grâce à la bague intérieure 9 et au joint annulaire 12, une étanchéité est créée entre le bord supérieur du conduit 4 et le tube 7, empêchant toute matière de pénétrer entre le conduit 4 et le tube 7 et d'atteindre l'étanchéité 3 et la paroi 1 autour du conduit de traversée 4.Thanks to the inner ring 9 and the annular seal 12, a seal is created between the upper edge of the duct 4 and the tube 7, preventing any material from entering between the duct 4 and the tube 7 and reaching the seal 3 and the wall 1 around the crossing duct 4.

La partie annulaire d'appui 11 de la bague 9 et le joint annulaire 12 qu'elle porte peuvent présenter des diamètres intérieurs et extérieurs tels que le dispositif 1 peut être associé à des conduits de traversée 4 présentant des diamètres différents.The annular support portion 11 of the ring 9 and the annular seal 12 that it carries may have inner and outer diameters such that the device 1 may be associated with bushings 4 having different diameters.

Le conduit 4, le tube 7 et la bague 9 peuvent être métalliques.The conduit 4, the tube 7 and the ring 9 may be metallic.

Le joint d'étanchéité 12 peut être en une matière de préférence apte à fluer sous l'effet d'une pression, de préférence non élastique ou faiblement élastique. Par exemple, le joint d'étanchéité 12 peut être en une matière bitumée ou en une matière élasto-plastique connue sous l'abréviation EPDM ou une mousse de polyuréthane à cellules ouvertes caoutchoutée, imprégnée de latex.The seal 12 may be of a material preferably capable of flowing under the effect of a pressure, preferably inelastic or weakly elastic. For example, the seal 12 may be of a bitumen material or an elastoplastic material known as EPDM or a latex-impregnated rubberized open cell polyurethane foam.

Selon une variante de réalisation, la partie supérieure 10 de la bague intérieure 9 pourrait comprendre une pluralité de branches s'étendant vers le haut, dont les bords d'extrémité supérieures pourraient en appui contre la face intérieure du tube 7.According to an alternative embodiment, the upper part 10 of the inner ring 9 could comprise a plurality of upwardly extending branches whose upper end edges could bear against the inner face of the tube 7.

La présente invention ne se limite pas aux exemples ci-dessus décrits. Bien d'autres variantes de réalisation sont possibles, sans sortir du cadre de l'invention, tel que défini par les revendications.The present invention is not limited to the examples described above. Many other embodiments are possible, without departing from the scope of the invention, as defined by the claims.
