Definitions

- a so-called sealed combustion heater does not draw air from its direct environment but at a distance from where it is installed.
- the air is generally taken near the place, for example the exterior of a building, where the fumes produced by combustion can be exhausted. That’s why he has been proposed, in the case of heaters with remote combustion air source to use a double walled pipe with concentric pipes in which a pipe inside conveys the smoke to be evacuated and an outside pipe conveys the combustion air to the heater using the annular space between the walls of the pipe inside and outside pipe.
- Today's double-walled flues are designed to so that a termination part is, for example, on the roof of a building extends vertically, the inner pipe leading upwards to allow the evacuation of combustion gases.

- the smoke flue may also include a bell attached above the pipe opening outside so that the air sucked in through the annular opening between the inner pipe and the outside pipe enters from below the bell.
- a first problem posed by known double-walled flues comes from the fact that the combustion gas discharged upwards through the opening of the pipe interior can nevertheless mix with the aspirated oxidant gas. This mixture can occur even if the oxidant gas is sucked under a bell.
- a second problem with known double-walled flues comes from the fact that the humidity present in the relatively hot gases evacuated by the inner pipe can condense and freeze when these gases are suddenly cooled when arriving outside. When the temperature is low, a heap of ice can form on the duct. On the one hand, such a mass of ice can hinder the operation of the duct, for example by preventing air from entering the duct, and, on the other hand, create other problems like falling ice.
- the present invention particularly relates to a double flue wall to solve the problems that have just been mentioned.

- said second bell element is fitted onto said pipe outside.
- said second bell element is fixed by crimping simultaneous of its wall and the wall of said outer pipe.
- said smoke outlet means is surmounted by a means forming an anti-refoulement cap comprising a ferrule surrounding said smoke outlet means and a helmet disposed above said ferrule so that smoke escapes between the upper end of said ferrule and the periphery of said helmet.
- said helmet comprises a lower wall of shape tapered tapering towards the bottom which is opposite said outlet means fumes.

- a conduit is made up of several conduit elements placed end to end. end.
- the present invention relates to the terminal duct element, a part of which provided with smoke outlet and combustion air inlet means is located outside the building.
- a terminal duct element 1 comprises overall an inner pipe 2 open at its upper end forming means of smoke outlet 3, an outer coaxial pipe 4 provided with an air inlet means 5 located in an air intake area located some distance below the smoke outlet zone, a bell 6 fixed to the periphery of the outer pipe 4 at the level of the air intake zone, a bell 16 fixed to the periphery of the inner pipe to close the gap between the interior and exterior pipes from above, and a set 8 covering the smoke outlet zone forming an anti-repression cap consisting of a ferrule 33 surmounted by a helmet 35.
- the inner 2 and outer 4 pipes are each of generally cylindrical shape circular.
- the outer pipe 4 has a diameter greater than the diameter of the pipe interior 2 so as to leave an annular space 9 between the interior pipe 2 and the external pipe 4 sufficient to allow the supply of combustion air to the heater.
- the inner pipe 2 is longer than the outer pipe 4 and exceeds the latter in the lower part of the terminal duct element 1 which facilitates the nesting of the latter on the flue.

- Two ways to fixing with nuts 7 crimped at the same height, diametrically opposite, on the pipe 4 allow the terminal duct element 1 to be fixed to a roof flashing 45, as can be seen in FIG. 5.
- a combustion air inlet means 5 consists of a plurality of holes formed around the outer pipe 4. This set of peripheral holes defines an air intake means or air intake 5 which is at a certain distance from the upper end of the terminal duct element 1.

- the fixing of the bell 16 on the inner pipe is done by fitting the inner pipe 2 in the bell 16 so that the outer wall of the pipe is pressed against the inner surface of the cylindrical part 20, then by expansion of the pipe inside.
- the expansion is carried out by means of a tube expansion device that we introduce into the pipe.

Abstract
Description
La présente invention concerne un dispositif de terminaison pour conduit de fumée à double paroi.The present invention relates to a termination device for double wall smoke.
Un conduit de fumée à double paroi est destiné à évacuer les gaz de combustion, d'une part, et à alimenter en air comburant, d'autre part, un ou plusieurs appareils de chauffage dits à combustion étanche, à combustible liquide ou gazeux.A double-walled flue is intended to evacuate the combustion gases, on the one hand, and to supply combustion air, on the other hand, one or more heating said to be sealed combustion, with liquid or gaseous fuel.
Un appareil de chauffage dit à combustion étanche ne prélève pas de l'air dans son environnement direct mais à distance de l'endroit où il est installé. L'air est généralement prélevé à proximité de l'endroit, par exemple l'extérieur d'un bâtiment, où les fumées produites par la combustion peuvent être évacuées. C'est pourquoi il a été proposé, dans le cas d'appareils de chauffage à source d'air comburant distante d'utiliser un conduit à double paroi à tuyaux concentriques dans lequel un tuyau intérieur véhicule les fumées à évacuer et un tuyau extérieur véhicule l'air comburant vers l'appareil de chauffage en utilisant l'espace annulaire entre les parois du tuyau intérieur et du tuyau extérieur.A so-called sealed combustion heater does not draw air from its direct environment but at a distance from where it is installed. The air is generally taken near the place, for example the exterior of a building, where the fumes produced by combustion can be exhausted. That’s why he has been proposed, in the case of heaters with remote combustion air source to use a double walled pipe with concentric pipes in which a pipe inside conveys the smoke to be evacuated and an outside pipe conveys the combustion air to the heater using the annular space between the walls of the pipe inside and outside pipe.
Les conduits de fumée à double parois existant à l'heure actuelle sont conçus de manière à ce qu'une partie de terminaison se trouvant, par exemple, sur le toit d'un bâtiment s'étende verticalement, le tuyau intérieur débouchant vers le haut pour permettre l'évacuation des gaz de combustion. Le tuyau extérieur débouche également vers le haut, mais son ouverture se trouve en dessous de l'ouverture du tuyau extérieur, de sorte que l'espace annulaire formant bouche d'arrivée d'air se trouve en dessous de l'ouverture du tuyau intérieur formant orifice d'évacuation des gaz de combustion. Le conduit de fumée comprend généralement un chapeau de protection installé au dessus de l'ouverture du tuyau intérieur, de manière à protéger cette ouverture tout en permettant l'évacuation des gaz de combustion. Le conduit de fumée peut également comprendre une cloche fixée au dessus de l'ouverture du tuyau extérieur de sorte que l'air aspiré par l'ouverture annulaire entre le tuyau intérieur et le tuyau extérieur entre par dessous la cloche.Today's double-walled flues are designed to so that a termination part is, for example, on the roof of a building extends vertically, the inner pipe leading upwards to allow the evacuation of combustion gases. The outer pipe also opens upwards, but its opening is below the opening of the pipe outside, so that the annular space forming the air intake opening is in below the opening of the inner pipe forming a gas exhaust port combustion. The flue generally includes a protective cap installed above the opening of the inner pipe, so as to protect this opening while allowing the evacuation of combustion gases. The smoke flue may also include a bell attached above the pipe opening outside so that the air sucked in through the annular opening between the inner pipe and the outside pipe enters from below the bell.
Un premier problème que posent les conduits de fumée à double paroi connus provient du fait que le gaz de combustion rejeté vers le haut par l'ouverture du tuyau intérieur peut néanmoins se mélanger avec le gaz comburant aspiré. Ce mélange peut se produire même si le gaz comburant est aspiré sous une cloche.A first problem posed by known double-walled flues comes from the fact that the combustion gas discharged upwards through the opening of the pipe interior can nevertheless mix with the aspirated oxidant gas. This mixture can occur even if the oxidant gas is sucked under a bell.
Un second problème que posent les conduits de fumée à double paroi connus provient du fait que l'humidité présente dans les gaz relativement chauds évacués par le tuyau intérieur peuvent se condenser puis geler lorsque ces gaz sont brutalement refroidis en arrivant à l'extérieur. Lorsque la température est basse, un amas de glace peut se former sur le conduit. Un tel amas de glace peut, d'une part, gêner le fonctionnement du conduit, par exemple en empêchant l'arrivée d'air dans le conduit, et, d'autre part, créer d'autres problèmes comme des chutes de glace.A second problem with known double-walled flues comes from the fact that the humidity present in the relatively hot gases evacuated by the inner pipe can condense and freeze when these gases are suddenly cooled when arriving outside. When the temperature is low, a heap of ice can form on the duct. On the one hand, such a mass of ice can hinder the operation of the duct, for example by preventing air from entering the duct, and, on the other hand, create other problems like falling ice.
La présente invention a notamment pour objet un conduit de fumée à double paroi permettant de résoudre les problèmes qui viennent d'être évoqués.The present invention particularly relates to a double flue wall to solve the problems that have just been mentioned.
La présente invention concerne un dispositif de terminaison de conduit de fumée à double paroi pour appareil de chauffage, ledit conduit de fumée comprenant un tuyau intérieur véhiculant les fumées à évacuer et un tuyau extérieur véhiculant l'air comburant vers l'appareil de chauffage en utilisant l'espace annulaire entre les parois du tuyau intérieur et du tuyau extérieur, caractérisé en ce que ledit dispositif de terminaison comprend un tuyau intérieur et un tuyau extérieur concentriques, prolongeant respectivement ledit tuyau intérieur et ledit tuyau extérieur dudit conduit, en ce que ledit tuyau intérieur débouche vers le haut de sorte que son extrémité supérieure forme moyen de sortie des fumées, en ce que ledit tuyau extérieur entoure ledit tuyau intérieur sur sensiblement toute la hauteur de ce dernier, et en ce qu'un moyen d'entrée d'air comburant est ménagé sur la périphérie dudit tuyau extérieur à une hauteur telle que ledit moyen d'entrée d'air se trouve en dessous et à distance dudit moyen de sortie des fumées.The present invention relates to a flue termination device double-walled heater, said flue comprising a inner pipe conveying the smoke to be evacuated and an outer pipe conveying air oxidizer to the heater using the annular space between the walls inner pipe and outer pipe, characterized in that said device termination includes an inner pipe and an outer concentric pipe, respectively extending said inner pipe and said outer pipe of said conduit, in that said inner pipe opens upwards so that its end upper form of smoke outlet, in that said outer pipe surrounds said inner pipe over substantially the entire height of the latter, and in that a combustion air inlet means is provided on the periphery of said external pipe to a height such that said air inlet means is below and at a distance of said smoke outlet means.
La distance entre les moyens d'entrée d'air et de sortie des fumées étant la plus importante possible, on limite grandement les risques de mélange entre les flux de gaz de combustion et d'air comburant. Etant donné que, par ailleurs, le tuyau extérieur continue à entourer le tuyau intérieur au dessus du moyen d'entrée d'air jusqu'au moyen de sortie des fumées, l'espace annulaire entre les parois de ces tuyaux peut servir de compartiment isolant permettant d'isoler thermiquement le conduit interne de l'air extérieur.The distance between the air intake and smoke outlet means being the most significant possible, the risks of mixing between the gas flows are greatly limited combustion and combustion air. Since, on the other hand, the outer pipe continues to surround the inner pipe above the air inlet means until smoke outlet means, the annular space between the walls of these pipes can serve as an insulating compartment allowing thermal insulation of the internal duct outside air.
Avantageusement, une couronne vient obstruer l'espace annulaire entre lesdits tuyaux intérieur et extérieur au dessus dudit moyen d'entrée d'air comburant.Advantageously, a crown obstructs the annular space between said inner and outer pipes above said combustion air inlet means.
Cette couronne ou anneau d'obturation permet d'orienter le flux d'air vers le bas et d'éviter les remontées d'air.This crown or obturation ring allows the air flow to be directed downwards and to avoid air rises.
Avantageusement, un premier élément en cloche vient obstruer l'espace annulaire entre lesdits tuyaux intérieur et extérieur au niveau de l'extrémité supérieure dudit tuyau extérieur.Advantageously, a first bell element obstructs the space annular between said inner and outer pipes at the upper end of said outer pipe.
Avantageusement, ledit premier élément en cloche est fixé par emboítement avec ledit tuyau intérieur.Advantageously, said first bell element is fixed by interlocking with said inner pipe.
Avantageusement, ledit premier élément en cloche est fixé par sertissage simultané de sa paroi et de la paroi dudit tuyau intérieur.Advantageously, said first bell element is fixed by crimping simultaneous of its wall and the wall of said inner pipe.
Avantageusement, l'espace annulaire entre lesdits tuyaux intérieur et extérieur est rempli d'un isolant thermique dans une zone commençant au dessus dudit moyen d'entrée d'air comburant et allant jusqu'à son extrémité supérieure.Advantageously, the annular space between said interior and exterior pipes is filled with thermal insulation in an area starting above said means combustion air inlet and going to its upper end.
Avantageusement, ledit moyen d'entrée d'air est constitué d'une pluralité de trous ménagés sur la périphérie dudit tuyau extérieur.Advantageously, said air inlet means consists of a plurality of holes made on the periphery of said outer pipe.
Avantageusement, un second élément en cloche est fixé par sa partie supérieure à la périphérie dudit tuyau extérieur, juste en dessus dudit moyen d'entrée d'air, de manière à ce que ledit second élément en cloche s'étende autour du tuyau extérieur en regard dudit moyen d'entrée d'air.Advantageously, a second bell element is fixed by its upper part at the periphery of said outer pipe, just above said air inlet means, so that said second bell member extends around the outer pipe in look of said air inlet means.
Ainsi, le moyen d'entrée d'air est protégé, l'air aspiré par le moyen d'entrée d'air rentrant par le dessous de la cloche.Thus, the air inlet means is protected, the air sucked in by the inlet means of air entering from below the bell.
Avantageusement, ledit second élément en cloche est emboíté sur ledit tuyau extérieur. Advantageously, said second bell element is fitted onto said pipe outside.
Avantageusement, ledit second élément en cloche est fixé par sertissage simultané de sa paroi et de la paroi dudit tuyau extérieur.Advantageously, said second bell element is fixed by crimping simultaneous of its wall and the wall of said outer pipe.
Selon un autre aspect de la présente invention, ledit moyen de sortie de fumée est surmonté d'un moyen formant chapeau anti-refouleur comprenant une virole entourant ledit moyen de sortie de fumée et un casque disposé au dessus de ladite virole de manière à ce que la fumée s'échappe entre l'extrémité supérieure de ladite virole et la périphérie dudit casque.According to another aspect of the present invention, said smoke outlet means is surmounted by a means forming an anti-refoulement cap comprising a ferrule surrounding said smoke outlet means and a helmet disposed above said ferrule so that smoke escapes between the upper end of said ferrule and the periphery of said helmet.
Avantageusement, ledit casque comprend une paroi inférieure de forme tronconique se rétrécissant vers le bas qui se trouve en regard dudit moyen de sortie des fumées.Advantageously, said helmet comprises a lower wall of shape tapered tapering towards the bottom which is opposite said outlet means fumes.
Avantageusement, une paroi de forme tronconique se rétrécissant vers le haut est ménagée autour de la partie supérieure dudit tube intérieur, l'angle d'inclinaison de cette paroi étant opposé à l'angle d'inclinaison de ladite paroi inférieure de forme tronconique dudit casque.Advantageously, a frustoconical wall narrowing upwards is formed around the upper part of said inner tube, the angle of inclination of this wall being opposite the angle of inclination of said lower shaped wall frustoconical of said helmet.
La disposition de ces deux parois tronconiques qui interviennent de part et d'autre de la virole, permet de former un ensemble aérodynamique facilitant la sortie des fumées tout en empêchant ces dernières de redescendre dans le conduit de cheminée par refoulement.The arrangement of these two frustoconical walls which intervene on both sides and on the other side of the shell, makes it possible to form an aerodynamic assembly facilitating the exit fumes while preventing them from going down into the flue discharge chimney.
Avantageusement ledit casque est constitué d'une paroi supérieure et d'une paroi inférieure, un compartiment vide ou rempli d'un isolant thermique étant ménagé entre ces deux parois.Advantageously, said helmet consists of an upper wall and a lower wall, an empty compartment or filled with thermal insulation being provided between these two walls.
Ce compartiment isolant contribue à éviter la formation de condensation sous le casque du chapeau.This insulating compartment helps prevent condensation from forming under the hat helmet.
Avantageusement, ledit casque est d'une taille telle que la périphérie dudit casque constitue la partie dudit dispositif de terminaison la plus éloignée de l'axe dudit dispositif de terminaison.Advantageously, said helmet is of a size such that the periphery of said helmet constitutes the part of said termination device furthest from the axis of said termination device.
Ainsi, les gouttelettes de condensation qui peuvent éventuellement se former au niveau de la périphérie du casque ou les gouttes d'eau provenant des eaux de pluie tombant sur le haut du casque sont suffisamment éloignées des zones qu'il convient de protéger d'une éventuelle formation de glace.Thus, the condensation droplets that can eventually form at the level of the periphery of the helmet or drops of water from rainwater falling on the top of the helmet are far enough away from the areas that should be protect from possible ice formation.
Les caractéristiques de l'invention mentionnées ci-dessus ainsi que d'autres
apparaítront plus clairement à la lecture de la description suivante d'un exemple de
réalisation, ladite description étant faite en relation avec les dessins joints, parmi
lesquels :
Dans l'exemple de réalisation représenté sur les Figs. 1 à 5, la présente invention s'applique à un conduit de fumée à double paroi pour appareil de chauffage à combustion à source d'air comburant distante. Un tel conduit comprend un tuyau intérieur véhiculant les fumées vers l'extérieur d'un bâtiment, l'air destiné à alimenter l'appareil de chauffage circulant, lui, de l'extérieur du bâtiment vers l'appareil de chauffage, dans l'espace annulaire créé entre le tuyau intérieur et le tuyau extérieur. Généralement, un tel conduit est constitué de plusieurs éléments de conduit mis bout à bout. La présente invention concerne l'élément de conduit terminal dont une partie pourvue de moyens de sortie des fumées et d'entrée d'air comburant se trouve à l'extérieur du bâtiment.In the embodiment shown in Figs. 1 to 5, the present invention applies to a double-walled flue for a space heater distant combustion air source combustion. Such a conduit includes a hose interior conveying smoke to the exterior of a building, the air intended to supply the heater circulating from the outside of the building to the heater heating, in the annular space created between the inner pipe and the outer pipe. Generally, such a conduit is made up of several conduit elements placed end to end. end. The present invention relates to the terminal duct element, a part of which provided with smoke outlet and combustion air inlet means is located outside the building.
En référence à la Fig. 1, un élément de conduit terminal 1 comprend
globalement un tuyau intérieur 2 ouvert à son extrémité supérieure formant moyen de
sortie de fumée 3, un tuyau extérieur coaxial 4 pourvu d'un moyen d'entrée d'air 5 se
trouvant dans une zone d'entrée d'air située à une certaine distance au dessous de la
zone de sortie des fumées, une cloche 6 fixée à la périphérie du tuyau extérieur 4 au
niveau de la zone d'entrée d'air, une cloche 16 fixée à la périphérie du tuyau intérieur
pour clore par le haut l'intervalle entre les tuyaux intérieur et extérieur, et un ensemble
8 coiffant la zone de sortie des fumées formant chapeau anti-refouleur constitué d'une
virole 33 surmontée d'un casque 35. With reference to FIG. 1, a terminal duct element 1 comprises
overall an
Les tuyaux intérieur 2 et extérieur 4 sont chacun de forme générale cylindrique
circulaire. Le tuyau extérieur 4 est d'un diamètre supérieur au diamètre du tuyau
intérieur 2 de manière à laisser un espace annulaire 9 entre le tuyau intérieur 2 et le
tuyau extérieur 4 suffisant pour permettre l'amenée d'air comburant à l'appareil de
chauffage.The inner 2 and outer 4 pipes are each of generally cylindrical shape
circular. The
Ainsi qu'on le voit bien sur la Fig. 1, le tuyau intérieur 2 est plus long que le
tuyau extérieur 4 et dépasse ce dernier en partie basse de l'élément de conduit terminal
1 ce qui facilite l'emboítement de ce dernier sur le conduit de fumée. Ce tuyau
intérieur 2 comprend à son extrémité inférieure un bord rentrant 21. L'extrémité
supérieure du tuyau intérieur 2 débouchant vers le haut forme la zone de sortie des
fumées 3.As can be seen in FIG. 1, the
Le tuyau extérieur 4 présente à son extrémité inférieure un bord rentrant 10 au
dessus duquel est ménagé un jonc 11 en saillie vers l'extérieur. Ce jonc 11 est destiné
à servir d'appui sur lequel vient porter l'extrémité supérieure du tuyau extérieur du
conduit de fumée, la partie située entre le jonc 11 et le bord rentrant 10 étant adaptée à
venir s'emboíter dans ce tuyau extérieur du conduit de fumée. Deux moyens de
fixation à écrous 7 sertis à la même hauteur, opposés diamétralement, sur le tuyau 4
permettent la fixation de l'élément de conduit terminal 1 sur un solin de toiture 45,
ainsi qu'on peut le voir sur la Fig. 5.The
Un moyen d'entrée d'air comburant 5 est constitué d'une pluralité de trous
ménagés en périphérie du tuyau extérieur 4. Cet ensemble de trous périphériques
définit un moyen d'entrée d'air ou prise d'air 5 qui se trouve à une certaine distance
de l'extrémité supérieure de l'élément de conduit terminal 1. Cette distance est prévue
pour que la zone d'entrée d'air 5 se trouve le plus loin possible de la zone de sortie des
fumées 3. Ainsi qu'on le voit bien sur la Fig. 5, lorsque l'élément de conduit terminal
1 est monté sur le toit d'un bâtiment, traversant une jupe tronconique 48 d'un solin de
toiture 45, la zone d'entrée d'air 5 se trouve à proximité de l'extrémité supérieure de
la jupe tronconique 48, dans la position la plus basse possible permettant une
aspiration d'air extérieure.A combustion air inlet means 5 consists of a plurality of holes
formed around the
Au dessus du moyen d'entrée d'air comburant 5 est ménagé un jonc en
renfoncement vers l'intérieur 12. Ce jonc 12 a deux fonctions. Tout d'abord, il sert au
sertissage de la cloche 6 sur le tuyau extérieur 4 ainsi qu'on le verra par la suite.
Ensuite, il sert de support à une couronne 19 permettant l'obturation de l'espace
annulaire 9 au dessus du moyen d'entrée d'air comburant 5. Above the combustion air inlet means 5 is formed a rod in
indentation inwards 12. This
Sur la partie supérieure du tuyau 4 est ménagé un jonc en saillie vers l'extérieur
servant de support à la cloche 16 adaptée à venir obstruer l'espace annulaire 9 entre
les tuyaux intérieur et extérieur au dessus du tuyau extérieur.On the upper part of the
Avantageusement, l'espace annulaire 9 entre les tuyaux intérieur et extérieur est
rempli d'un isolant thermique dans la zone située entre l'anneau 19 et l'extrémité
supérieure du tuyau extérieur 4 recouvert par la cloche 16.Advantageously, the
La cloche 6 comprend en son sommet une première partie cylindrique de
diamètre légèrement supérieur au diamètre du tuyau extérieur 4 de manière à
permettre un emboítement de la cloche sur ce dernier puis, vers le bas, un évasement
de forme tronconique 14 puis une seconde partie cylindrique 15 sur laquelle est
ménagé un jonc en renfoncement vers l'intérieur permettant d'empêcher l'intrusion de
volatiles dans le moyen d'entrée d'air et de rigidifier la cloche au niveau de son
extrémité basse. La partie cylindrique supérieure permet, comme il est décrit ci-dessous,
la fixation de la cloche à la périphérie du tuyau extérieur, juste en dessus de
la zone d'entrée d'air, de manière à ce que la seconde partie cylindrique 15 s'étende
autour du tuyau extérieur en regard des trous d'entrée d'air 5, à une distance suffisante
pour permettre le passage de l'air par dessous la cloche.The
La fixation de la cloche 6 sur le tuyau extérieur se fait par emboítement du tuyau
extérieur 4 dans la cloche 6 de sorte que la paroi extérieure du tuyau est plaquée
contre la surface intérieure de la partie cylindrique supérieure de la cloche, puis par
sertissage de cette partie cylindrique dans le jonc 12. Le sertissage est conduit au
moyen d'un dispositif de sertissage de tube adapté à venir entourer le tuyau.The fixing of the
Ainsi qu'on le voit bien sur la Fig. 2, la cloche 16 comprend en son sommet une
première partie cylindrique 20 de diamètre légèrement supérieur au diamètre du tuyau
intérieur 2 de manière à permettre un emboítement de la cloche sur ce dernier, puis,
vers le bas, un évasement de forme tronconique 18 puis une seconde partie cylindrique
17 qui prend appui sur le jonc 13 du tuyau extérieur. L'inclinaison vers le haut de la
paroi 18 contribue à améliorer les performances aérodynamiques du chapeau anti-refouleur.As can be seen in FIG. 2, the
La fixation de la cloche 16 sur le tuyau intérieur se fait par emboítement du
tuyau intérieur 2 dans la cloche 16 de sorte que la paroi extérieur du tuyau est plaquée
contre la surface intérieure de la partie cylindrique 20, puis par expansion du tuyau
intérieur. L'expansion est conduite au moyen d'un dispositif d'expansion de tube
qu'on introduit dans le tuyau. La Fig. 2 montre l'assemblage du tuyau intérieur et de
la cloche avant expansion et la Fig. 2bis montre cet assemblage après expansion. Ainsi
qu'on le voit sur la Fig. 2bis, après expansion, le tuyau intérieur 2 comprend de haut
en bas un premier bord évasé 25 vers l'extérieur puis une partie cylindrique 26 de plus
grand diamètre que cette même partie avant expansion puis une partie en saillie vers
l'extérieur formant intérieurement une gorge trapézoïdale 27. La déformation du tuyau
intérieur 2 entraíne une déformation correspondante de la partie cylindrique 20 de la
cloche 16, de sorte qu'est formée une clé mécanique entre le tuyau intérieur 2 et la
cloche 16 permettant la fixation de cette dernière.The fixing of the
L'ensemble coiffant la zone de sortie des fumées forme un chapeau anti-refouleur.
En référence à la Fig. 3, ce chapeau comprend globalement un cylindre de
fixation 28, une virole 33 entourant la zone de sortie de fumées et un casque de
chapeau 35 disposé au-dessus de ladite virole de manière à ce que la fumée s'échappe
entre l'extrémité supérieure de ladite virole et la périphérie dudit casque, l'ensemble
étant maintenu cohérent au moyen de pattes de liaison 32 soudées à ces différents
éléments.The assembly covering the smoke outlet zone forms an anti-repression cap.
With reference to FIG. 3, this hat generally comprises a cylinder of
Le cylindre 28 a un diamètre sensiblement inférieur au diamètre de la partie
supérieure du tuyau intérieur 2 après expansion ce qui permet l'emboítement du
cylindre dans ce tuyau. Il est bien entendu ouvert, prolongeant en pratique le tuyau
intérieur 2 de manière à laisser sortir les fumées au niveau de son extrémité
supérieure. L'extrémité inférieure du cylindre 28 est pourvue d'un bord rentrant vers
l'intérieur 29 tandis que au niveau de l'extrémité supérieure de ce cylindre est ménagé
un jonc en saillie vers l'extérieur 30 destiné à prendre appui sur le bord évasé 25 de
l'extrémité supérieure du tuyau intérieur 2. Par ailleurs, une patte de fixation par
enclipsage 24 est ménagée sur ce cylindre 28, cette patte étant destinée à venir en prise
avec la gorge trapézoïdale 27 du tuyau intérieur 2. Le jonc 30 en appui sur le bord
évasé 25 et la patte 24 en prise avec la gorge trapézoïdale 27 constituent une clé
mécanique immobilisant le chapeau anti-refouleur sur le tuyau intérieur. Pour
démonter le chapeau anti-refouleur, il faut repousser la patte 24 ce qui est possible au
moyen d'un objet allongé comme un tournevis introduit à travers un percement 23
ménagé à cet effet sur la partie supérieure de la cloche 16, au niveau de la gorge
trapézoïdale 27, ainsi qu'on peut le voir sur la Fig. 2bis.The
Sur les parois intérieures du cylindre 28, au niveau de l'extrémité supérieure de
ce dernier, sont soudées les pattes de liaison 32 préalablement formées de manière à
servir de distanceur entre le cylindre 28 et la virole 33. On the inner walls of the
La virole 33 est de forme cylindrique et s'étend suivant l'axe de l'ensemble de
l'élément de conduit terminal 1. Elle est d'un diamètre légèrement supérieur au
diamètre extérieur de la cloche 16 et par conséquent au diamètre du tuyau extérieur 4.
Des joncs 42 sont ménagés au niveau d'une partie inférieure et d'une partie supérieure
de la virole 33. Ces joncs font saillie vers l'extérieur. La virole 33 entoure l'orifice de
sortie des fumées, l'extrémité supérieure du cylindre 28 se trouvant entre les deux
joncs 42, légèrement plus proche du jonc inférieur. Les pattes de liaison 32, venant du
cylindre 28, remontent le long de la paroi intérieure de la virole à laquelle elles sont
soudées. Cette virole forme corps du chapeau anti-refouleur. Elle est notamment
destinée à protéger la sortie des fumées des rafales de vent et des entrées de pluie dans
le tuyau intérieur 2.The
Le casque 35 est composé d'une pièce inférieure et d'une pièce supérieure
assemblées par soudure par point. La pièce inférieure 34 comporte, du centre vers la
périphérie, un méplat horizontal 39, une partie tronconique 38 inclinée vers le haut
puis, à la périphérie, un bord plat 37 légèrement incliné vers le bas formant une goutte
d'eau. La pièce supérieure 36 est un disque dont la périphérie suit le bord descendant
de la pièce inférieure 34.The
La partie tronconique 38 décrit un angle identique à celui que décrit la partie
tronconique 18 de la cloche 16 dans le sens opposé. Ces deux parties tronconiques
opposées associées à la virole 33 forment un ensemble aérodynamique facilitant la
sortie des fumées tout en empêchant ces dernières de redescendre dans le conduit de
cheminée par refoulement.The
Entre les deux pièces 34 et 36 est ménagé un compartiment 40 vide ou rempli
d'un isolant thermique. Ce compartiment isolant contribue à éviter la formation de
condensation sous le casque du chapeau.Between the two
Le casque 35 est maintenu au dessus de la virole 33 au moyen des pattes 32
soudées à la périphérie de la partie tronconique 38. Le diamètre de ce casque est
supérieur au diamètre de la cloche 6 de façon à éloigner de l'ensemble de l'élément de
conduit terminal les eaux de pluie tombant sur la pièce supérieure de ce casque.The
Pour une meilleure compréhension, les dispositifs décrits aux Fig. 2bis et Fig.3
sont représentés de manière assemblée à la Fig. 4. Sur cette Fig., on remarque que le
bord évasé 25 vient en contact avec le jonc 30 et que la patte 24 s'enclipse dans la
gorge trapézoïdale 27. Ainsi, la virole 33 est solidement liée à la cloche 16. For a better understanding, the devices described in Figs. 2bis and Fig. 3
are shown assembled in FIG. 4. In this Fig., We notice that the
flared
La Fig. 5 représente l'installation de l'élément de conduit terminal 1 associé à
un dispositif d'étanchéité sur le toit d'un bâtiment. Un système étanche de traversée de
toiture 44 comprend un solin de toiture 45 formé d'une plaque d'embase 46 équipée
d'une bavette souple ou malléable 47 à sa partie basse puis d'une jupe tronconique 48
soudée sur la plaque d'embase 46, d'un jonc 52 en renfoncement vers l'intérieur et de
deux pattes 49 situées en regard l'une de l'autre de part et d'autre de la partie
supérieure de la jupe tronconique, ces pattes étant percées chacune d'un orifice 50.Fig. 5 shows the installation of the terminal duct element 1 associated with
a sealing device on the roof of a building. A waterproof crossing system of
roof 44 comprises a roof flashing 45 formed by a
Les orifices 50 permettent la fixation par vissage de l'élément de conduit
terminal 1 par l'intermédiaire des écrous 7 de cet élément 1. Ce système de fixation
autorise un réglage angulaire suivant les différentes pentes du toit, le blocage définitif
de l'élément de conduit étant assuré lors de l'emboítement des éléments de conduit
inférieurs. Le réglage angulaire du solin 45 est effectué par pivotement de la jupe
tronconique 48 autour de l'axe de l'orifice 50 qui est situé dans un plan parallèle à
celui du toit et dans une direction perpendiculaire à la direction de plus grande pente
du toit. Ainsi, le solin 45 prend place sur le toit de manière ajustée.The
Au dessus du solin 45, un larmier 51 formant une rejetée d'eau est serré sur le
corps de l'élément de conduit terminal entre le solin 45 et la cloche de prise d'air 6.
Ce larmier 51 évite l'entrée d'eau ou de volatiles à l'intérieur du solin 45.Above the flashing 45, a
