Description

La présente invention concerne un dispositif d'étanchéité pour le bâtiment, en particulier pour un toit, et un procédé pour sa fabrication.The present invention relates to a sealing device for the building, in particular for a roof, and a method for its manufacture.

Les toits des bâtiments, notamment les dalles plates de toits, présentent des passages traversants qui sont prévus pour l'écoulement des eaux de pluie ou le passage de cheminées. Les conduits d'écoulement ou de cheminée doivent être reliés de façon étanche aux étanchéités aménagées sur les dalles.The roofs of buildings, in particular the flat slabs of roofs, have through passages which are provided for the flow of rainwater or the passage of chimneys. The drains or chimneys must be connected in a watertight manner to the seals provided on the slabs.

Le brevet EP-B1-1 710 365 décrit un dispositif d'étanchéité qui comprend un conduit muni à une extrémité d'une membrane souple radiale. La membrane présente une portion annulaire axiale prise entre une portion d'extrémité du conduit et une bague de montage intérieure.The patent EP-B1-1 710 365 describes a sealing device which comprises a duct provided at one end with a radial flexible membrane. The membrane has an axial annular portion caught between an end portion of the duct and an inner mounting ring.

Ce dispositif d'étanchéité a pour inconvénient majeur de nécessiter l'utilisation d'une bague de montage intérieure rapportée.This sealing device has the major drawback of requiring the use of an attached inner mounting ring.

Une telle solution à bague rapportée présente des inconvénients notamment en termes d'étanchéité et de résistance mécanique.Such an attached ring solution has drawbacks, particularly in terms of sealing and mechanical strength.

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

L'invention concerne un dispositif d'étanchéité pour le bâtiment comprenant un conduit et un organe de liaison monté autour et solidaire du conduit.The invention relates to a sealing device for the building comprising a conduit and a connecting member mounted around and secured to the conduit.

Selon une caractéristique générale, le conduit comprend une portion principale axiale autour de laquelle est monté l'organe de liaison, un bourrelet radial formé sur la portion principale et s'étendant radialement vers l'extérieur, et une portion distale d'extrémité prolongeant radialement vers l'extérieur la portion principale et qui est axialement en vis-à-vis du bourrelet pour former entre eux une fente de montage annulaire ouverte radialement vers l'extérieur. La portion distale d'extrémité s'étend radialement au-delà du bourrelet.According to a general characteristic, the duct comprises an axial main portion around which the connecting member is mounted, a radial bead formed on the main portion and extending radially outwards, and a distal end portion extending radially outwardly the main portion and which is axially facing the bead to form between them an annular mounting slot open radially outwards. The distal end portion extends radially beyond the bead.

Selon une autre caractéristique générale, la portion principale, la portion distale d'extrémité et le bourrelet du conduit sont réalisés en une seule pièce.According to another general characteristic, the main portion, the distal end portion and the bead of the duct are made in one piece.

Selon une autre caractéristique générale, l'organe de liaison est monté dans la fente de montage et enserré axialement entre le bourrelet et la portion distale d'extrémité du conduit.According to another general characteristic, the connecting member is mounted in the mounting slot and clamped axially between the bead and the distal end portion of the duct.

Selon une autre caractéristique générale, la portion distale d'extrémité du conduit comprend au moins une déformation locale s'étendant du côté de l'organe de liaison et engagée dans ledit organe de liaison.According to another general characteristic, the distal end portion of the duct comprises at least one local deformation extending from the side of the connecting member and engaged in said connecting member.

Ainsi, la fixation de l'organe de liaison est obtenue uniquement par le conduit qui est réalisé en une seule pièce. Il n'est pas nécessaire de prévoir l'utilisation de pièce additionnelle et rapportée pour réaliser cette fixation de l'organe de liaison.Thus, the attachment of the connecting member is obtained only by the conduit which is made in one piece. It is not necessary to provide for the use of additional and added parts to achieve this fixing of the connecting member.

La prévision d'un bourrelet s'étendant radialement vers l'extérieur permet l'obtention d'un dispositif d'étanchéité qui soit robuste et fiable dans le temps en limitant le risque d'apparition d'amorces de rupture qui peuvent exister avec un bourrelet s'étendant obliquement.The provision of a bead extending radially outwards makes it possible to obtain a sealing device which is robust and reliable over time by limiting the risk of the appearance of incipient fractures which may exist with a bead extending obliquely.

En outre, la réalisation de la portion distale d'extrémité qui s'étend radialement au-delà du bourrelet permet de limiter son décollement vers le haut lorsqu'une couche extérieure d'étanchéité est appliquée par thermo-soudure sur cette portion distale d'extrémité lors de l'installation du dispositif d'étanchéité sur une dalle de toit.In addition, the realization of the distal end portion which extends radially beyond the bead makes it possible to limit its upward detachment when an outer sealing layer is applied by heat-welding on this distal portion of end when installing the waterproofing device on a roof slab.

On limite ainsi le risque d'infiltrations d'eau entre la portion distale du conduit et l'organe de liaison, ainsi qu'un déchirement de cette couche extérieure d'étanchéité appliquée.This limits the risk of water infiltration between the distal portion of the duct and the connecting member, as well as a tearing of this outer layer of sealing applied.

Au surplus, la ou les déformations locales prévues sur la portion distale d'extrémité du conduit assurent une fonction de blocage de l'organe de liaison qui empêche son glissement radial, notamment si la portion distale d'extrémité vient à se décoller légèrement lorsqu'est appliquée par thermo-soudure la couche extérieure d'étanchéité. Ceci limite encore le risque d'infiltrations d'eau.Moreover, the local deformation or deformations provided on the distal end portion of the duct provide a blocking function of the connecting member which prevents its radial sliding, in particular if the distal end portion comes off slightly when is applied by thermo-welding the outer waterproofing layer. This further limits the risk of water infiltration.

Par ailleurs, la fabrication du dispositif d'étanchéité est réalisée avec un faible nombre d'opérations de déformations plastiques du conduit. En outre, compte tenu de l'orientation radiale de la fente de montage, l'organe de liaison peut présenter une forme simple, par exemple plate.Furthermore, the manufacture of the sealing device is carried out with a small number of plastic deformation operations of the pipe. In addition, given the radial orientation of the mounting slot, the connecting member may have a simple shape, for example flat.

Ladite déformation locale de la portion distale d'extrémité du conduit peut par exemple être décalée radialement vers l'extérieur par rapport au bourrelet.Said local deformation of the distal end portion of the duct can for example be offset radially outwards with respect to the bead.

Ladite déformation locale de la portion distale d'extrémité du conduit est avantageusement engagée dans un évidement complémentaire de l'organe de liaison. Cet évidement peut être obtenu par déformation de l'organe de liaison elle-même formée par ladite déformation locale de la portion distale d'extrémité du conduit.Said local deformation of the distal end portion of the duct is advantageously engaged in a complementary recess of the connecting member. This recess can be obtained by deformation of the connecting member itself formed by said local deformation of the distal end portion of the duct.

Dans un mode de réalisation, l'extrémité libre de la portion distale d'extrémité du conduit est pliée du côté de l'organe de liaison et forme ladite déformation locale.In one embodiment, the free end of the distal end portion of the duct is bent on the side of the connecting member and forms said local deformation.

Alternativement ou en combinaison, il pourrait être possible de prévoir d'autres types de déformation(s) locale(s) s'engageant dans l'organe de liaison, par exemple des nervures ou bourrelets axiaux. De tels bourrelets peuvent être situés sur la portion distale du conduit de sorte à être décalés vers l'extérieur par rapport au bourrelet ou être formés sur la zone de la portion distale située dans le prolongement axial du bourreletAlternatively or in combination, it could be possible to provide other types of local deformation(s) engaging in the connecting member, for example ribs or axial beads. Such beads can be located on the distal portion of the duct so as to be offset towards the outside with respect to the bead or be formed on the zone of the distal portion located in the axial extension of the bead

De préférence, ladite déformation locale de la portion distale d'extrémité du conduit est annulaire. Ceci favorise encore l'obtention d'un accrochage sur l'organe de liaison. Alternativement, la portion distale d'extrémité du conduit pourrait comprend une pluralité de déformations espacées les uns par rapport aux autres dans le sens circonférentiel.Preferably, said local deformation of the distal end portion of the duct is annular. This further promotes obtaining an attachment on the connecting member. Alternatively, the distal end portion of the duct could comprise a plurality of deformations spaced apart from each other in the circumferential direction.

Avantageusement, la dimension radiale de la portion distale d'extrémité du conduit est au moins égale à une fois et demi la dimension radiale du bourrelet. Un tel dimensionnement limite le risque de décollement vers le haut de la portion distale d'extrémité du conduit lors de l'application de la couche extérieure d'étanchéité. La dimension radiale de la portion distale d'extrémité du conduit peut être au moins égale à deux fois la dimension radiale du bourrelet.Advantageously, the radial dimension of the distal end portion of the duct is at least equal to one and a half times the radial dimension of the bead. Such dimensioning limits the risk of the distal end portion of the duct detaching upwards during application of the outer sealing layer. The dimension radial dimension of the distal end portion of the duct may be at least equal to twice the radial dimension of the bead.

Préférentiellement, l'organe de liaison est enserré axialement entre le bourrelet et la portion distale d'extrémité du conduit sur au moins une zone radiale annulaire. Ceci favorise encore l'obtention d'une bonne étanchéité entre l'organe de liaison et le conduit.Preferably, the connecting member is clamped axially between the bead and the distal end portion of the duct over at least one annular radial zone. This further promotes obtaining a good seal between the connecting member and the duct.

Dans un mode de réalisation, le bourrelet est formé par une portion proximale et par une portion intermédiaire de la portion principale qui sont reliées entre elles par un pli annulaire, la portion intermédiaire étant axialement en vis-à-vis de la portion distale d'extrémité et située axialement entre la portion distale et la portion proximale. La fente de montage annulaire peut alors être formée entre la portion distale d'extrémité et la portion intermédiaire du bourrelet.In one embodiment, the bead is formed by a proximal portion and by an intermediate portion of the main portion which are interconnected by an annular fold, the intermediate portion being axially opposite the distal portion of end and located axially between the distal portion and the proximal portion. The annular mounting slot can then be formed between the distal end portion and the intermediate portion of the bead.

L'organe de liaison comprend une platine. Dans un mode de réalisation particulier, l'organe de liaison comprend en outre une plaque de renfort montée autour de la portion principale du conduit et engagée dans la fente de montage, la plaque de renfort étant enserrée axialement entre le bourrelet du conduit et la platine.The connecting member comprises a plate. In a particular embodiment, the connecting member further comprises a reinforcing plate mounted around the main portion of the duct and engaged in the mounting slot, the reinforcing plate being clamped axially between the bead of the duct and the plate .

  • une étape de compression axiale de la portion distale d'extrémité et du bourrelet de la portion principale du conduit pour sertir axialement entre eux l'organe de liaison à l'intérieur de la fente de montage. La portion distale d'extrémité du conduit s'étend radialement au-delà du bourrelet.
The invention also relates to a method of manufacturing a sealing device for the building comprising a conduit and a connecting member, the method comprising the following steps:
  • a step of mounting the connecting member around the duct,
  • a step of deforming a main axial portion of the duct to form at least in part a radial bead extending radially outwards,
  • a step of bending a distal end portion of the duct in the direction of the bead to form between them at least partly an annular mounting slot open radially outwards and inside which is located partly the liaison body, and
  • a step of axially compressing the distal end portion and the bead of the main portion of the duct to crimp the connecting member axially between them inside the slot disassembly. The distal end portion of the duct extends radially beyond the bead.

Le procédé comprend également une étape de déformation de la portion distale d'extrémité du conduit pour former au moins une déformation s'étendant du côté de l'organe de liaison et engagée dans ledit organe de liaison.The method also comprises a step of deforming the distal end portion of the duct to form at least one deformation extending from the side of the connecting member and engaged in said connecting member.

L'étape de montage de l'organe de liaison autour du conduit peut être réalisée avant l'étape de déformation de la portion principale du conduit pour former au moins en partie le bourrelet, ou en variante après cette étape de déformation.The step of mounting the connecting member around the duct can be carried out before the step of deforming the main portion of the duct to form at least part of the bead, or alternatively after this deformation step.

L'invention concerne encore un autre procédé de fabrication d'un dispositif d'étanchéité pour le bâtiment comprenant un conduit et un organe de liaison, le procédé comprenant les étapes suivantes :

  • une étape de montage de l'organe de liaison autour du conduit pourvu d'un bourrelet radial préformé,
  • une étape de pliage d'une portion distale d'extrémité du conduit en direction du bourrelet radial préformé pour former entre eux au moins en partie une fente de montage annulaire ouverte radialement vers l'extérieur et à l'intérieur de laquelle est situé en partie l'organe de liaison, et
  • une étape de compression axiale de la portion distale d'extrémité et du bourrelet radial préformé de la portion principale du conduit pour sertir axialement entre eux l'organe de liaison à l'intérieur de la fente de montage. La portion distale d'extrémité du conduit s'étend radialement au-delà du bourrelet.
The invention relates to yet another method for manufacturing a sealing device for the building comprising a conduit and a connecting member, the method comprising the following steps:
  • a step of mounting the connecting member around the duct provided with a preformed radial bead,
  • a step of bending a distal end portion of the duct in the direction of the preformed radial bead to form between them at least partly an annular mounting slot open radially outwards and inside which is located partly the liaison body, and
  • a step of axial compression of the distal end portion and of the preformed radial bead of the main portion of the duct to crimp the connecting member axially between them inside the mounting slot. The distal end portion of the duct extends radially beyond the bead.

Le procédé comprend également une étape de déformation de la portion distale d'extrémité du conduit pour former au moins une déformation s'étendant du côté de l'organe de liaison et engagée dans ledit organe de liaison.The method also comprises a step of deforming the distal end portion of the duct to form at least one deformation extending from the side of the connecting member and engaged in said connecting member.

Dans un mode de mise en œuvre particulier, le procédé comprend en outre, simultanément à l'étape de pliage de la portion distale d'extrémité de la portion principale, une étape de déformation radiale du bourrelet du conduit. L'étape de pliage de la portion distale d'extrémité du conduit peut comprendre une première phase durant laquelle uniquement la portion distale d'extrémité est déformée par pliage en direction du bourrelet, et une deuxième phase successive durant laquelle le pliage de la portion distale d'extrémité en direction du bourrelet se poursuit et durant laquelle est réalisée simultanément l'étape de déformation radiale du bourrelet du conduit.In a particular mode of implementation, the method further comprises, simultaneously with the step of bending the distal end portion of the main portion, a step of radially deforming the bead of the duct. The step of bending the distal end portion of the conduit may comprise a first phase during which only the distal end portion is deformed by folding in the direction of the bead, and a second successive phase during which the folding of the distal end portion in the direction of the bead continues and during which the deformation step is carried out simultaneously radial of the bead of the duct.

Dans un mode de mise en œuvre particulier, le procédé comprend, durant l'étape de montage de l'organe de liaison autour du conduit, le montage autour dudit conduit d'une platine et d'une plaque de renfort axialement en-dessous de la platine.In a particular mode of implementation, the method comprises, during the step of mounting the connecting member around the duct, the mounting around said duct of a plate and of a reinforcement plate axially below platinum.

Dans un mode de mise en œuvre particulier, durant l'étape de déformation de la portion distale d'extrémité du conduit, l'extrémité libre de ladite portion distale est pliée du côté de l'organe de liaison pour former ladite déformation locale.In a particular mode of implementation, during the step of deforming the distal end portion of the duct, the free end of said distal portion is bent on the side of the connecting member to form said local deformation.

Sur les figures 1 et 2 est représenté un dispositif d'étanchéité, référencé 10 dans son ensemble qui comprend un conduit 12, d'axe X-X', et une platine 14 de liaison solidaire du conduit. Le dispositif 10 est représenté dans un position supposée verticale.On the figure 1 and 2 is shown a sealing device, referenced 10 as a whole, which comprises a conduit 12, of axis X-X', and a connecting plate 14 secured to the conduit. The device 10 is shown in an assumed vertical position.

Le conduit 12 comprend successivement une portion principale 16 axiale annulaire et une portion distale 18 d'extrémité radiale annulaire. La portion distale 18 délimite l'extrémité libre du conduit 12. La portion distale 18 prolonge radialement vers l'extérieur la portion principale 16. La portion distale 18 prolonge l'extrémité supérieure de la portion principale 16. La portion principale 16 du conduit est ici de forme cylindrique. En variante, il pourrait être possible d'avoir une portion principale 16 présentant en section droite une autre forme que circulaire, par exemple polygonale.The conduit 12 successively comprises a main annular axial portion 16 and a distal portion 18 of annular radial end. Distal portion 18 delimits the free end of conduit 12. Distal portion 18 extends main portion 16 radially outwards. Distal portion 18 extends the upper end of main portion 16. Main portion 16 of the conduit is here cylindrical in shape. As a variant, it could be possible to have a main portion 16 having in cross section a shape other than circular, for example polygonal.

Le conduit 12 comprend également un bourrelet 20 annulaire formé sur la portion principale 16 axialement à distance de la portion distale 18. Le bourrelet 20 s'étend radialement vers l'extérieur par rapport à la portion principale 16. La portion distale 18 s'étend radialement au-delà du bourrelet 20. De préférence, la dimension radiale de la portion distale 18 est au moins égale à une fois et demi la dimension radiale du bourrelet 20, et encore plus préférentiellement au moins égale à deux fois la dimension radiale du bourrelet 20.The duct 12 also comprises an annular bead 20 formed on the main portion 16 axially at a distance from the distal portion 18. The bead 20 extends radially outwards with respect to the main portion 16. The distal portion 18 extends radially beyond the bead 20. Preferably, the radial dimension of the distal portion 18 is at least equal to one and a half times the radial dimension of the bead 20, and even more preferably at least equal to twice the radial dimension of the bead 20.

Le bourrelet 20 est formé par une portion proximale 22 annulaire et par une portion intermédiaire 24 annulaire de la portion principale 16. Les portions proximale 22 et intermédiaire 24 s'étendent radialement chacune vers l'extérieur par rapport à la portion principale 16. Les portions proximale 22 et intermédiaire 24 sont reliées entre elles par un pli 26 annulaire. Le pli 26 présente une forme concave orientée radialement vers l'intérieur.The bead 20 is formed by a proximal annular portion 22 and by an intermediate annular portion 24 of the main portion 16. The proximal 22 and intermediate 24 portions each extend radially outwards with respect to the main portion 16. The portions proximal 22 and intermediate 24 are interconnected by an annular fold 26. The fold 26 has a concave shape oriented radially inward.

Les portions proximale 22 et intermédiaire 24 du bourrelet sont axialement en vis-à-vis et en contact axialement l'une contre l'autre. La portion intermédiaire 24 est située axialement entre la portion proximale 22 et la portion distale 18. La portion intermédiaire 24 est axialement en vis-à-vis de la portion distale 18 d'extrémité en étant axialement à distance de celle-ci.The proximal 22 and intermediate 24 portions of the bead are axially facing each other and in axial contact with each other. The intermediate portion 24 is located axially between the proximal portion 22 and the distal portion 18. The intermediate portion 24 is axially opposite the distal end portion 18 while being axially at a distance therefrom.

La portion distale 18 du conduit et la portion intermédiaire 24 du bourrelet 20 aménagent entre elles une fente 28 de montage annulaire ouverte radialement vers l'extérieur. La portion principale 16 forme le fond annulaire de la fente 28 qui est par conséquent borgne. Dans l'exemple de réalisation illustré, la fente 28 présente une section en forme de U orienté radialement.The distal portion 18 of the duct and the intermediate portion 24 of the bead 20 arrange between them an annular mounting slot 28 open radially outwards. The main portion 16 forms the annular bottom of the slot 28 which is therefore blind. In the illustrated embodiment, the slot 28 has a radially oriented U-shaped section.

Le conduit 12 est réalisé en une seule pièce, c'est-à-dire que la portion principale 18, la portion distale 20 et le bourrelet 20 sont venus de matière, i.e. monoblocs.The duct 12 is made in one piece, that is to say that the main portion 18, the distal portion 20 and the bead 20 are made in one piece, i.e. in one piece.

La platine 14 de liaison est pourvue d'une ouverture 14a traversante pour son montage sur le conduit 12. La platine 14 est montée autour de la portion principale 16 du conduit. Le diamètre intérieur de l'ouverture 14a est supérieur au diamètre extérieur de la portion principale 16. La platine 14 est engagée dans la fente 28 formée entre la portion distale 18 et le bourrelet 20. La platine 14 est prise ou enserrée axialement dans la fente 28 entre la portion distale 18 et le bourrelet 20. Ceci permet la solidarisation de la platine 14 au conduit 12. Les deux faces radiales opposées de la platine 14 définissant son épaisseur sont en contact contre la portion distale 18 et contre la portion intermédiaire 24 du bourrelet. La platine 14 est enserrée axialement à l'intérieur de la fente 28 entre la portion distale 18 et la portion intermédiaire 24 du bourrelet. La platine 14 s'étend radialement en saillie en-dehors de la fente 28.The connecting plate 14 is provided with a through opening 14a for its mounting on the duct 12. The plate 14 is mounted around the main portion 16 of the duct. The inside diameter of the opening 14a is greater than the outside diameter of the main portion 16. The plate 14 is engaged in the slot 28 formed between the distal portion 18 and the bead 20. The plate 14 is taken or clamped axially in the slot 28 between the distal portion 18 and the bead 20. This allows the attachment of the plate 14 to the conduit 12. The two opposite radial faces of the plate 14 defining its thickness are in contact against the distal portion 18 and against the intermediate portion 24 of the bead. The plate 14 is clamped axially inside the slot 28 between the distal portion 18 and the intermediate portion 24 of the bead. Plate 14 projects radially outside of slot 28.

La partie d'extrémité libre 29 annulaire de la portion distale 18 du conduit est pliée du côté de la platine 14 et s'engage dans la platine 14. La partie d'extrémité libre 29 s'étend ici obliquement du côté de la platine 14. Un pli 30 annulaire est formé entre la partie d'extrémité libre 29 de la portion distale 18 et le reste de la portion distale 18 qui s'étend radialement.The annular free end part 29 of the distal portion 18 of the duct is bent on the side of the plate 14 and engages in the plate 14. The free end part 29 here extends obliquely on the side of the plate 14 An annular fold 30 is formed between the free end portion 29 of the distal portion 18 and the remainder of the distal portion 18 which extends radially.

La partie d'extrémité libre 29 annulaire de la portion distale 18 s'engage dans la platine 14 en déformant localement la platine, en l'espèce en déformant localement la face radiale de la platine 14 en contact contre la portion distale 18. Un évidement (non référencé) complémentaire est formé sur cette face radiale à l'intérieur duquel s'engage la partie d'extrémité libre 29 annulaire de la portion distale 18. Cet évidement est formé par déformation locale de la face radiale de la platine 14. Le pli 30 forme un pli de rigidification de la portion distale 18 du conduit. La partie d'extrémité libre 29 forme une déformation locale de la portion distale 18.The annular free end part 29 of the distal portion 18 engages in the plate 14 by locally deforming the plate, in this case by locally deforming the radial face of the plate 14 in contact against the distal portion 18. A recess (not referenced) complementary is formed on this radial face inside which engages the annular free end part 29 of the distal portion 18. This recess is formed by local deformation of the radial face of the plate 14. The fold 30 forms a stiffening fold of the distal portion 18 of the duct. The free end part 29 forms a local deformation of the distal portion 18.

A titre d'exemple, le conduit 12 peut être réalisé en matière métallique, par exemple en tôle galvanisée ou en aluminium, ou encore en une matière plastique ou en toute autre matière adaptée. La platine 14 de liaison peut être en une matière bitumée, sous la forme d'une membrane souple, ou encore en matière métallique, par exemple en une tôle emboutie, ou encore en matière plastique ou en toute autre matière adaptée.By way of example, the duct 12 can be made of metallic material, for example galvanized sheet metal or aluminum, or else of a plastic material or any other suitable material. The connecting plate 14 can be made of a bituminous material, in the form of a flexible membrane, or even of metallic material, for example of stamped sheet metal, or even of plastic material or any other suitable material.

Selon une utilisation illustrée sur la figure 3, le dispositif d'étanchéité 10 peut être installé sur une dalle 31 d'un toit plat ou en pente pour constituer une liaison étanche, par exemple de la manière suivante.According to an illustrated use on the picture 3 , the sealing device 10 can be installed on a slab 31 of a flat or sloping roof to form a sealed connection, for example in the following manner.

Un trou 32 étant ménagé au travers de la dalle 31, on dépose une sous-couche 34 d'étanchéité sur la face supérieure de la dalle 31, jusqu'à proximité de ce trou 32.A hole 32 being made through the slab 31, a sealing sub-layer 34 is deposited on the upper face of the slab 31, up to the proximity of this hole 32.

On engage axialement du haut vers le bas la portion principale 16 du conduit 12 dans le trou 32, jusqu'à ce que la platine 14 repose sur la sous-couche 34 d'étanchéité et adhère à cette dernière.The main portion 16 of the duct 12 is engaged axially from top to bottom in the hole 32, until the plate 14 rests on the sealing sub-layer 34 and adheres to the latter.

Puis, on peut déposer une couche extérieure 36 d'étanchéité sur la sous-couche 34 et sur la platine 14, en laissant libre d'accès le passage vertical intérieur délimité par le conduit 12.Then, an outer layer 36 of sealing can be deposited on the underlayer 34 and on the plate 14, leaving free access to the interior vertical passage delimited by the conduit 12.

Lors de la pose ou postérieurement, l'extrémité inférieure de la portion principale 16 du conduit 12 est engagée dans l'extrémité supérieure d'un conduit d'évacuation 38.During installation or subsequently, the lower end of the main portion 16 of the duct 12 is engaged in the upper end of an evacuation duct 38.

La sous-couche 34 et la couche extérieure 36 d'étanchéité sont généralement en une matière bitumée, posées à chaud. Ainsi, la sous-couche 34 adhère à la dalle 31, la couche extérieure 36 adhère à la sous-couche 34 et la platine 14 adhère à la fois à la sous-couche 34 et à la couche extérieure 36.The underlayer 34 and the outer sealing layer 36 are generally made of a bituminous material, placed hot. Thus, the underlayer 34 adheres to the slab 31, the outer layer 36 adheres to the underlayer 34 and the plate 14 adheres to both the underlayer 34 and the outer layer 36.

Selon une variante d'utilisation, le dispositif d'étanchéité 10 peut être installé à l'envers, c'est-à-dire dans une position telle que la portion principale 16 du conduit 12 s'étend vers le haut en saillie vers le haut par rapport à la dalle 31, la platine 14 étant posée sur la dalle 31 entre les couches d'étanchéité 34 et 36.According to a variant of use, the sealing device 10 can be installed upside down, that is to say in a position such that the main portion 16 of the conduit 12 extends upwards projecting towards the high relative to the slab 31, the plate 14 being placed on the slab 31 between the sealing layers 34 and 36.

En référence aux figures 4 à 11, on va maintenant décrire un exemple de mise en œuvre du procédé de fabrication du dispositif d'étanchéité 10 permettant l'obtention du conduit 12 en une pièce et la solidarisation de la platine 14 au conduit.With reference to figures 4 to 11 , we will now describe an example of implementation of the method of manufacturing the sealing device 10 allowing the obtaining of the conduit 12 in one piece and the joining of the plate 14 to the conduit.

Dans cet exemple de fabrication, il est utilisé une machine 40 équipée d'une plaque 42 de maintien extérieure équipée d'un épaulement 44 formant butée pour l'extrémité inférieure du conduit 12. La plaque 42 délimite un passage 46 vertical à l'intérieur duquel est monté le conduit 12. Le passage 46 est équipé intérieurement d'une gorge 48 annulaire qui s'étend radialement dans la plaque au voisinage d'une face supérieure radiale de celle-ci. En variante, la gorge 48 pourrait déboucher sur la face supérieure de la plaque.In this manufacturing example, a machine 40 is used equipped with an outer retaining plate 42 equipped with a shoulder 44 forming a stop for the lower end of the conduit 12. The plate 42 delimits a vertical passage 46 inside which is mounted the conduit 12. The passage 46 is internally equipped with an annular groove 48 which extends radially in the plate in the vicinity of a radial upper face thereof. As a variant, the groove 48 could open onto the upper face of the plate.

Dans une première étape du procédé, on procède au montage du conduit 12 sur la machine 40. Comme illustré à la figure 4, on dispose initialement du conduit 12 présentant une forme rectiligne d'un bout à l'autre, que l'on place verticalement au travers du passage 46 de la plaque 42 et qu'on amène en appui contre l'épaulement 44. Le conduit 12 est engagé à l'intérieur du passage 46 avec un léger jeu radial.In a first step of the process, the pipe 12 is mounted on the machine 40. As illustrated in figure 4 , there is initially the conduit 12 having a rectilinear shape from one end to the other, which is placed vertically through the passage 46 of the plate 42 and which is brought into abutment against the shoulder 44. The conduit 12 is engaged inside the passage 46 with a slight radial play.

Le conduit 12 est disposé dans un position verticale telle qu'il s'étend axialement en saillie par rapport à la face supérieure de la plaque 42. Lors de cette étape ou précédemment, la platine 14 est montée avec un jeu radial autour du conduit 12. La platine 14 vient axialement en appui contre la face supérieure de la plaque 42.The conduit 12 is arranged in a vertical position such that it extends axially projecting relative to the upper face of the plate 42. During this step or previously, the plate 14 is mounted with radial play around the conduit 12 The plate 14 bears axially against the upper face of the plate 42.

La machine 40 comprend également un gabarit 50 cylindrique de maintien intérieur engagé à l'intérieur du conduit 12 avec un léger jeu radial. Le gabarit 50 est situé axialement en retrait de la gorge 48 de la plaque.The machine 40 also includes a cylindrical template 50 for internal support engaged inside the duct 12 with a slight radial play. The template 50 is located axially set back from the groove 48 of the plate.

Ensuite, lors de cette première étape du procédé, une plaque 52 de maintien supérieure est amenée axialement en appui contre la platine 14. La plaque 52 délimite un passage 54 vertical à l'intérieur duquel est montée la partie du conduit 12 en saillie hors de la plaque 42.Then, during this first step of the method, an upper retaining plate 52 is brought axially into abutment against the plate 14. The plate 52 delimits a vertical passage 54 inside which is mounted the part of the conduit 12 projecting out of the plate 42.

A ce stade, le conduit 12 est toujours formé uniquement de la portion principale 16.At this stage, conduit 12 is still formed solely of main portion 16.

Comme cela est illustré à la figure 5, la machine 40 comprend également un outil de déformation ou poinçon 56 qui est pourvu extérieurement d'un épaulement 58 annulaire.As illustrated in the figure 5 , the machine 40 also comprises a deformation tool or punch 56 which is externally provided with an annular shoulder 58.

Dans une deuxième étape du procédé, on procède à la déformation radiale vers l'extérieur de la portion principale 16 du conduit 12 axialement en-dessous de la platine 14.In a second step of the process, one proceeds to the radial outward deformation of the main portion 16 of the conduit 12 axially below the plate 14.

Pour ce faire, lors de cette étape, le poinçon 56 est introduit axialement à l'intérieur de la plaque 52 et à l'intérieur du conduit 12 avec un jeu radial, puis vient axialement en appui contre l'extrémité supérieure du conduit 12 par l'intermédiaire de l'épaulement 58 et continue de se déplacer axialement jusqu'à venir en appui contre le gabarit 50 comme cela est illustré à la figure 6.To do this, during this step, the punch 56 is introduced axially inside the plate 52 and inside the duct 12 with a radial clearance, then comes axially to bear against the upper end of the duct 12 by through the shoulder 58 and continues to move axially until it comes to rest against the template 50 as shown in figure 6 .

L'effort axial exercé par le poinçon 56 sur l'extrémité supérieure du conduit 12 provoque une déformation radiale vers l'extérieur de manière locale de la portion principale 16 du conduit 12 à l'intérieur de la gorge 48 de la plaque 42.The axial force exerted by the punch 56 on the upper end of the duct 12 causes local radial outward deformation of the main portion 16 of the duct 12 inside the groove 48 of the plate 42.

Cette deuxième étape du procédé permet de préformer le bourrelet 20 sur la portion principale 16 du conduit.This second step of the method makes it possible to preform the bead 20 on the main portion 16 of the duct.

Comme illustré à la figure 7, le poinçon 56 est ensuite extrait axialement vers le haut en dehors du conduit 12. Puis, le gabarit 50 est également retiré.As shown in figure 7 , the punch 56 is then extracted axially upwards outside the duct 12. Then, the template 50 is also removed.

Par la suite, dans une troisième étape du procédé, on procède au pliage de la partie de la portion principale 16 qui est située axialement au-dessus de la préforme du bourrelet 20 et de la platine 14 pour préformer la portion distale 18.Subsequently, in a third step of the method, the part of the main portion 16 which is located axially above the preform of the bead 20 and of the plate 14 is folded to preform the distal portion 18.

Lors d'une première phase de cette troisième étape, on commence par retirer la plaque 52 de la machine. Ensuite, comme cela est illustré à la figure 8, un outil de formage 60 de la machine qui est pourvu extérieurement d'une partie tronconique 62 est amené axialement à l'intérieur du conduit 12 jusqu'à ce que cette partie tronconique soit verticalement à la hauteur de la partie de la portion principale 16 qui est située axialement au-dessus de la platine 14.During a first phase of this third step, one begins by removing the plate 52 from the machine. Then, as shown in figure 8 , a forming tool 60 of the machine which is externally provided with a frustoconical part 62 is brought axially inside the duct 12 until this part tapered either vertically at the height of the part of the main portion 16 which is located axially above the plate 14.

Puis, comme cela est représenté à la figure 9, l'outil de formage 60 est actionné radialement vers l'extérieur afin de plier vers l'extérieur la partie de la portion principale 16 qui s'étend en saillie axialement au-dessus de la platine 14 en direction de la préforme du bourrelet 20 et de la platine 14. Ceci provoque la formation d'un pli 64 annulaire sur la portion principale 16 du conduit à partir duquel s'étend la préforme de la portion distale 18. A ce stade, la préforme de la portion distale 18 s'étend obliquement. Le pliage de la préforme de la portion distale 18 permet aussi de préformer la fente 28 entre celle-ci et la préforme du bourrelet 20.Then, as shown in figure 9 , the forming tool 60 is actuated radially outward in order to bend outward the part of the main portion 16 which projects axially above the plate 14 in the direction of the preform of the bead 20 and the plate 14. This causes the formation of an annular fold 64 on the main portion 16 of the conduit from which extends the preform of the distal portion 18. At this stage, the preform of the distal portion 18 extends obliquely. The folding of the preform of the distal portion 18 also makes it possible to preform the slot 28 between the latter and the preform of the bead 20.

Lorsque l'outil de formage 60 a atteint une position radiale intérieure prédéterminée, ici au voisinage de l'alésage du conduit 12, alors il est ramené dans sa position initiale avant d'être extrait axialement vers le haut.When the forming tool 60 has reached a predetermined internal radial position, here in the vicinity of the bore of the duct 12, then it is returned to its initial position before being extracted axially upwards.

Ensuite, dans une deuxième phase de la troisième étape, la plaque 42 horizontale est retirée, et une autre plaque 66 horizontale de la machine est utilisée comme cela est illustré à la figure 10. La plaque 66 est équipée d'un passage 68 vertical au travers duquel s'étend le conduit 12 avec un léger jeu radial.Then, in a second phase of the third stage, the horizontal plate 42 is removed, and another horizontal plate 66 of the machine is used as illustrated in figure 10 . Plate 66 is equipped with a vertical passage 68 through which conduit 12 extends with a slight radial play.

Le passage 68 de la plaque est équipé intérieurement d'une gorge 70 annulaire qui s'étend radialement dans l'épaisseur de la plaque et débouche sur une face supérieure radiale de celle-ci. L'alésage de la gorge 70 est prévu pour être légèrement supérieur au diamètre extérieur de la préforme du bourrelet 20. Cette préforme du bourrelet 20 vient axialement en appui contre l'extrémité supérieure du passage 68 à partir de laquelle est formée la gorge 70. La platine 14 est située axialement à distance de la face supérieure de plaque 66 horizontale.The passage 68 of the plate is internally equipped with an annular groove 70 which extends radially in the thickness of the plate and opens onto a radial upper face thereof. The bore of the groove 70 is designed to be slightly larger than the outer diameter of the preform of the bead 20. This preform of the bead 20 bears axially against the upper end of the passage 68 from which the groove 70 is formed. The plate 14 is located axially at a distance from the upper face of the horizontal plate 66.

Par la suite, dans une quatrième étape du procédé, un outil de sertissage 72 (figures 11 et 12) vient axialement en appui contre la préforme de la portion distale 18 du conduit, et est déplacé axialement vers le bas pour la rabattre axialement contre la platine 14 et pour comprimer axialement, contre la plaque 66 qui est maintenue fixe, l'empilement axial constitué de la portion distale 18 du conduit, de la platine 14 et du bourrelet 20 du conduit. La portion distale 18, la fente 28 et le bourrelet 20 sont définitivement formés lors de cette étape du procédé. Lors de cette quatrième étape, les portions proximale 22 et intermédiaire 24 du bourrelet viennent axialement en contact l'une contre l'autre. La platine 14 est également enserrée axialement par compression axiale dans la fente 28 entre la portion distale 18 et le bourrelet 20 du conduit.Subsequently, in a fourth step of the process, a crimping tool 72 ( figure 11 and 12 ) bears axially against the preform of the distal portion 18 of the duct, and is moved axially downwards to fold it axially against the plate 14 and to compress axially against the plate 66 which is held fixed, the axial stack consisting of the distal portion 18 of the duct, the plate 14 and the bead 20 of the duct. The distal portion 18, the slot 28 and the bead 20 are definitively formed during this step of the method. During this fourth step, the proximal 22 and intermediate 24 portions of the bead come into axial contact with one another. The plate 14 is also clamped axially by axial compression in the slot 28 between the distal portion 18 and the bead 20 of the duct.

Ce faisant, l'écartement axial entre la portion distale 18 et la portion intermédiaire 24 du bourrelet est réduit et la platine 14 est enserré axialement, de façon étanche, entre ces deux portions. Il en résulte un montage par sertissage de la platine 14 à l'intérieur de la fente 28 délimitée entre la portion distale 18 et le bourrelet 20 du conduit est monté par sertissage le montage est effectué par sertissage.In doing so, the axial separation between the distal portion 18 and the intermediate portion 24 of the bead is reduced and the plate 14 is clamped axially, in a sealed manner, between these two portions. This results in an assembly by crimping of the plate 14 inside the slot 28 delimited between the distal portion 18 and the bead 20 of the duct is mounted by crimping the assembly is carried out by crimping.

Dans cet exemple de mise en œuvre, l'outil de sertissage 72 comprend une protubérance 74 annulaire de forme tronconique pour obtenir simultanément, au sertissage de la platine 14, le pliage de la partie d'extrémité libre 29 annulaire de la portion distale 18 du côté de la platine. La partie d'extrémité libre 29 s'engage dans la platine 14 par déformation locale de ladite platine. L'évidement complémentaire à la partie d'extrémité libre 29 est formé par cette déformation locale.In this example of implementation, the crimping tool 72 comprises an annular protrusion 74 of frustoconical shape to simultaneously obtain, when crimping the plate 14, the bending of the annular free end part 29 of the distal portion 18 of the side of the plate. The free end part 29 engages in the plate 14 by local deformation of said plate. The recess complementary to the free end part 29 is formed by this local deformation.

Enfin, dans une cinquième et dernière étape du procédé, on retire l'outil de sertissage 72 et la plaque 66, et on obtient le dispositif d'étanchéité 10 décrit et illustré à la figure 1.Finally, in a fifth and final step of the method, the crimping tool 72 and the plate 66 are removed, and the sealing device 10 described and illustrated in FIG. figure 1 .

Dans l'exemple de mise en œuvre du procédé qui vient d'être décrit, la déformation locale de la portion distale 18 du conduit pour plier la partie d'extrémité libre 29 est réalisée simultanément au sertissage de la platine 14 à l'intérieur de la fente 28 délimitée entre la portion distale 18 et le bourrelet 20 du conduit. En variante, cette étape de déformation locale par pliage pourrait être réalisée successivement à l'étape de sertissage axial de la platine 14.In the example of implementation of the method which has just been described, the local deformation of the distal portion 18 of the conduit to bend the free end part 29 is carried out simultaneously with the crimping of the plate 14 inside the slot 28 delimited between the distal portion 18 and the bead 20 of the duct. As a variant, this step of local deformation by bending could be carried out successively to the step of axial crimping of the plate 14.

Par ailleurs, dans l'exemple de mise en œuvre du procédé qui vient d'être décrit, il est prévu une unique phase de pliage de la partie de la portion principale 16 qui est située axialement au-dessus de la platine 14 pour préformer la portion distale 18.Furthermore, in the example of implementation of the method which has just been described, there is provided a single phase of folding the part of the main portion 16 which is located axially above the plate 14 to preform the distal portion 18.

En variante, après la deuxième phase de la troisième étape, il est possible de prévoir une deuxième phase de pliage. Dans ce cas, un deuxième outil de formage de la machine qui est pourvu extérieurement d'une partie tronconique, de conicité supérieure à celle de l'outil de formage 60, vient appuyer axialement contre la préforme de la portion distale 18 du conduit pour poursuivre le pliage de celle-ci autour du pli 64 précédemment formé et en direction de la préforme du bourrelet 20. Lorsque cet outil de formage a atteint une position axiale prédéterminée, alors il est retiré axialement vers le haut. Lors de cette deuxième phase du pliage, la préforme de la portion distale 18 du conduit s'étend encore obliquement vers le haut.As a variant, after the second phase of the third step, it is possible to provide a second folding phase. In this case, a second forming tool of the machine which is externally provided with a frustoconical part, of greater conicity than that of the forming tool 60, presses axially against the preform of the distal portion 18 of the duct to continue the folding of the latter around the fold 64 previously formed and in the direction of the preform of the bead 20. When this forming tool has reached a predetermined axial position, then it is withdrawn axially upwards. During this second phase of bending, the preform of the distal portion 18 of the duct still extends obliquely upwards.

Simultanément à cette deuxième phase de pliage de la préforme de la portion distale 18, le conduit 12 peut être déplacé axialement vers le haut en direction de l'outil de formage.Simultaneously with this second phase of folding the preform of the distal portion 18, the conduit 12 can be moved axially upwards in the direction of the forming tool.

Comme indiqué précédemment, la platine 14 forme un organe de liaison permettant d'installer le dispositif sur le toit d'un bâtiment. Dans ce premier exemple, l'organe de liaison est ainsi formé uniquement par la platine 14.As indicated above, the plate 14 forms a connecting member allowing the device to be installed on the roof of a building. In this first example, the connecting member is thus formed solely by plate 14.

L'exemple de réalisation illustré à la figure 12, sur laquelle les éléments identiques portent les mêmes références, diffère du premier exemple décrit en ce que l'organe de liaison comprend en outre une plaque de renfort 80 montée autour de la portion axiale 16 du conduit et engagée à l'intérieur de la fente 28 formée entre la portion distale 18 et le bourrelet 20 du conduit. Dans ce deuxième exemple, l'organe de liaison est donc formé par la platine 14 et par la plaque de renfort 80.The embodiment illustrated in figure 12 , on which the identical elements bear the same references, differs from the first example described in that the connecting member further comprises a reinforcing plate 80 mounted around the axial portion 16 of the duct and engaged inside the slot 28 formed between the distal portion 18 and the bead 20 of the conduit. In this second example, the connecting member is therefore formed by the plate 14 and by the reinforcing plate 80.

La plaque de renfort 80 s'étend radialement en saillie en-dehors de la fente 28. La plaque de renfort 80 est pourvue d'une ouverture 80a traversante pour son montage sur le conduit 12. La plaque de renfort 80 est enserrée axialement entre la platine 14 et le bourrelet 20, plus précisément la portion intermédiaire 24 de celui-ci.Reinforcement plate 80 extends radially projecting outside of slot 28. Reinforcement plate 80 is provided with a through opening 80a for mounting it on conduit 12. Reinforcement plate 80 is clamped axially between the plate 14 and bead 20, more precisely the intermediate portion 24 thereof.

Le même procédé que celui décrit précédemment peut être mis en œuvre pour l'obtention du dispositif 10 de ce deuxième exemple, avec un montage de la plaque de renfort 80 sur le conduit 12 simultanément au montage de la platine 14.The same method as that described above can be implemented to obtain the device 10 of this second example, with a mounting of the reinforcement plate 80 on the conduit 12 simultaneously with the mounting of the plate 14.

Dans les exemples de mise en œuvre précédemment décrits, le montage sur le conduit 12 de la platine 14, ou de la platine 14 et de la plaque de renfort 80, s'effectue avant la déformation radiale de la portion principale 16 du conduit qui est réalisée pour préformer le bourrelet 20. Alternativement, il pourrait être possible de prévoir ce montage après déformation radiale de la portion principale 16 du conduit.In the examples of implementation previously described, the assembly on the duct 12 of the plate 14, or of the plate 14 and the reinforcement plate 80, is carried out before the radial deformation of the main portion 16 of the duct which is made to preform the bead 20. Alternatively, it could be possible to provide this assembly after radial deformation of the main portion 16 of the duct.

Dans une autre variante de réalisation, il est également possible de réaliser le montage de la platine 14, ou de la platine 14 et de la plaque de renfort 80, sur un conduit pourvu d'un bourrelet préformé sur un site de fabrication séparé.In another alternative embodiment, it is also possible to mount the plate 14, or the plate 14 and the reinforcement plate 80, on a conduit provided with a preformed bead on a separate manufacturing site.
