Abstract
Description
La présente invention a pour objet un boisseau en terre cuite pour la réalisation de conduits de fumées.The subject of the present invention is a terracotta bushel for the construction of flues.
Un conduit de fumée selon le préambule de la
revendication 1 est connu du document EP-A-0 353 658.A flue according to the preamble of the
Il est fréquent d'utiliser, pour la réalisation de conduits de fumées, notamment de chaudières, des boisseaux alvéolés en terre cuite, qui sont superposés et assemblés les uns aux autres par un mortier de liaison.It is frequent to use, for the realization of conduits of fumes, in particular from boilers, plugged bushels in terracotta, which are superimposed and joined to each other by a mortar of link.
Avec une chaudière classique, les fumées de sortie de la chaudière sont à une température de l'ordre de 200 à 300°C, de telle sorte qu'il s'agit de fumées sèches, la condensation résultant de l'évacuation de ces fumées étant très faible et pouvant se produire uniquement en partie haute de la cheminée, après traversée du toit.With a conventional boiler, the exhaust fumes from the boiler are at a temperature of the order of 200 to 300 ° C, such so that it is dry smoke, the condensation resulting from the evacuation of this smoke being very weak and being able to occur only in the upper part of the chimney, after crossing the roof.
Au cours de ces dernières années, se sont développées les chaudières à haut rendement et à basse température, fonctionnant au fioule et au gaz, dans lesquelles la température de sortie des fumées est de l'ordre de 140 à 180°C. Compte tenu de la température relativement basse de ces fumées, il se produit une condensation importante à l'intérieur du conduit de fumées, pouvant conduire, pour une chaudière domestique, à une condensation de plusieurs litres par jour. Outre le fait qu'il convient d'évacuer le condensat en pied du conduit de fumées, il convient de réaliser ce conduit afin qu'il résiste aux attaques acides des condensats.In recent years, the high efficiency and low temperature boilers, operating at fuel and gas, in which the smoke outlet temperature is in the range of 140 to 180 ° C. Given the relatively low temperature low of these fumes, there is significant condensation at the interior of the flue, which can lead, for a boiler domestic, to a condensation of several liters per day. Apart from the fact that that the condensate should be removed at the bottom of the flue pipe, there this duct should be made so that it resists acid attacks by condensates.
De façon connue, les conduits de fumées peuvent être réalisés en terre cuite, en béton, ou en métal.In known manner, the flues can be made in terracotta, concrete, or metal.
Un conduit de fumées en terre cuite nécessite que la face intérieure du conduit soit munie d'un revêtement, par exemple en céramique émaillée. Toutefois, il se pose toujours le problème du joint, le mortier ne résistant pas aux attaques acides. Les boisseaux en béton ne conviennent pas pour les chaudières à basse température. Dans la mesure où du métal doit être utilisé, il convient de mettre en oeuvre de l'acier inoxydable, qui résiste à la corrosion mais qui est d'un prix de revient très élevé.A terracotta flue requires that the face interior of the duct is provided with a coating, for example in glazed ceramic. However, there is still the problem of the joint, the mortar not resistant to acid attack. Concrete bushels do not not suitable for low temperature boilers. Insofar where metal should be used, steel should be used stainless, which resists corrosion but which is very cost effective Student.
Le but de l'invention est de fournir un boisseau de cheminée qui soit polyvalent, c'est-à-dire convienne tout aussi bien pour les chaudières hautes températures que pour les chaudières basses températures, en résistant à la fois aux condensats et à la corrosion résultant de ceux-ci, et aux hautes températures, dans la mesure où la cheminée est associée à une chaudière haute température.The object of the invention is to provide a bushel that is versatile, that is to say equally suitable for high temperature boilers only for low boilers temperatures, resisting both condensate and corrosion resulting from these, and at high temperatures, to the extent that the chimney is associated with a high temperature boiler.
Le but est atteint par un conduit de fumée tel que
défini dans la revendication 1.The goal is reached by a smoke pipe such as
defined in
Il faut tout d'abord noter que dans ce boisseau, il y a une dissociation de fonction entre le matériau de jointoiement imperméable et résistant à la température, qui est situé du côté de l'intérieur du conduit et qui résiste à la corrosion, et le mortier d'assemblage qui, servant uniquement à l'assemblage, n'est pas en contact avec les condensats, dans la mesure où il est situé du côté de l'extérieur du conduit. En outre, par les dimensions respectives des emboítures situées du côté de l'intérieur, et destinées à recevoir le matériau de jointoiement, et des emboítures situées à l'extérieur et destinées à recevoir le mortier de liaison, l'opérateur est certain, s'il prend les précautions minimales requises, qu'il existe une bonne étanchéité au niveau des emboítures intérieures, c'est-à-dire celles au niveau desquelles se trouve le matériau de jointoiement.It should first be noted that in this bushel there is a dissociation of function between the waterproof jointing material and temperature resistant, which is located on the inside of the duct and which resists corrosion, and the assembly mortar which, serving only during assembly, is not in contact with condensates, as long as it is located on the outside of the duct. In addition, by the respective dimensions of the sockets located on the side of inside, and intended to receive the jointing material, and sockets located outside and intended to receive the mortar of connection, the operator is certain, if he takes the minimum precautions required, that there is a good seal at the sockets interior, i.e. those at which the material is located jointing.
Suivant une forme avantageuse d'exécution de l'invention, du côté intérieur du boisseau, l'emboíture disposée à l'extrémité inférieure est une emboíture mâle et l'emboíture disposée à l'extrémité supérieure est une emboíture femelle.According to an advantageous embodiment of the invention, the inner side of the plug, the socket arranged at the lower end is a male socket and the socket arranged at the upper end is a female socket.
Suivant une forme d'exécution de l'invention, la hauteur de l'emboíture mâle située du côté intérieur à une extrémité du boisseau est de l'ordre de 13 mm, tandis que la hauteur de l'emboíture femelle située du côté intérieur à l'autre extrémité du boisseau est de l'ordre de 6 à 7 mm.According to an embodiment of the invention, the height of the male socket located on the inside at one end of the plug is about 13 mm, while the height of the female socket located from the inner side to the other end of the plug is in the range of 6 to 7 mm.
Conformément à une caractéristique avantageuse de l'invention, le matériau de jointoiement intérieur est un mastic silicone résistant aux hautes températures.In accordance with an advantageous characteristic of the invention, the interior jointing material is a silicone sealant resistant to high temperatures.
Suivant une autre caractéristique de l'invention, la paroi intérieure du boisseau est recouverte d'un revêtement de résine à base de polyuréthanne stable jusqu'à 400°C.According to another characteristic of the invention, the wall inside of the bushel is covered with a resin coating based on polyurethane stable up to 400 ° C.
Ce revêtement intérieur peut également être constitué par un émaillage, une vitrification, ou un engobage.This interior coating can also be constituted by a enameling, vitrification, or engobing.
De toute façon, l'invention sera bien comprise à l'aide de la
description qui suit, en référence au dessin schématique annexé
représentant, à titre d'exemples non limitatifs plusieurs formes d'exécution
de ce boisseau :
La figure 1 représente deux boisseaux 2 superposés, coupés
longitudinalement, réalisés en terre cuite, et présentant une paroi
extérieure 3 de forme générale rectangulaire, et une paroi intérieure 4 de
section générale circulaire, les deux parois 3 et 4 étant reliées par des
cloisons intermédiaires 5 délimitant des alvéoles 6. La paroi intérieure 4 est
revêtue d'un matériau imperméable, et résistant à la corrosion, tel qu'un
revêtement de résine à base de polyuréthanne stable jusqu'à 400°C.Figure 1 shows two overlapping
Dans la forme d'exécution représentée aux figures 1 et 2,
chaque boisseau 2 comporte, à son extrémité inférieure, et du côté de la
paroi intérieure 4, une emboíture mâle 7, et du côté extérieur, une
emboíture femelle 8, l'emboíture mâle 7 et l'emboíture femelle 8 étant
reliées l'une à l'autre par une surface 9 inclinée.In the embodiment shown in Figures 1 and 2,
each
Chaque boisseau comporte, à son extrémité supérieure, et du
côté de la paroi intérieure, une emboíture femelle 10, et du côté extérieur
une emboíture mâle 12 reliées par une surface inclinée 13. Each bushel has, at its upper end, and
side of the inner wall, a
Il doit être noté que la différence de hauteur entre l'emboíture
mâle 7 et l'emboíture femelle 8 est de l'ordre de 13 mm, alors que la
différence de hauteur entre l'emboíture femelle 10 et l'emboíture mâle 12
est de l'ordre de 6 à 7 mm. Pour réaliser l'assemblage de deux boisseaux,
un joint de mastic 14 est déposé du côté intérieur, dans l'emboíture
femelle 10, et un joint de mortier 15 est déposé sur l'emboíture mâle 12,
avant mise en place du boisseau disposé directement au-dessus.It should be noted that the difference in height between the socket
male 7 and the
Compte tenu des dimensions respectives des différentes
emboítures, l'emboíture mâle 7 se trouve plus près de l'emboíture femelle
10 que l'emboíture mâle 12 ne se trouve de l'emboíture femelle 8,
assurant ainsi que le joint 14 de mastic silicone résistant aux hautes
températures est parfaitement comprimé et garantissant par là même
l'étanchéité de l'intérieur du conduit et sa résistance à la corrosion.Taking into account the respective dimensions of the different
sockets, male socket 7 is closer to the
Les figures 3 et 4 représentent des variantes d'exécution des
emboítures du boisseau. La figure 3 est une variante d'exécution très
similaire à la figure 2, dans laquelle les mêmes éléments sont désignés par
les mêmes références que précédemment affectées de l'indice a. Dans ce
cas, seules changent les zones de raccordement entre les emboítures
extérieures et intérieures, qui ne sont plus constituées par des zones
inclinées, mais par des surfaces rectangulaires 16, 17.Figures 3 and 4 show alternative embodiments of
bushel sockets. Figure 3 is an alternative embodiment very
similar to Figure 2, in which the same elements are designated by
the same references as previously assigned to the index a. In this
only change the connection areas between the sockets
external and internal, which are no longer constituted by zones
inclined, but by
La figure 4 représente une autre variante d'exécution, dans
laquelle chaque boisseau comporte à son extrémité inférieure deux
emboítures mâles, à savoir une emboíture mâle 7b située du côté intérieur
et une emboíture mâle 18 située du côté extérieur, l'extrémité supérieure
de chaque boisseau comportant deux emboítures femelles, une emboíture
femelle 10b située du côté intérieur et une emboíture femelle 19 située du
côté extérieur. La distance entre l'emboíture mâle 7b et l'emboíture
femelle 10b est inférieure à la distance entre l'emboíture mâle 18 et
l'emboíture femelle 19. Les deux emboítures mâles 7b et 18 sont séparées
par un évidement rectangulaire 20, tandis que les emboítures femelles 10b
et 19 sont séparées par une nervure rectangulaire 22.FIG. 4 represents another alternative embodiment, in
which each bushel has at its lower end two
male sockets, namely a male socket 7b located on the inner side
and a
Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce boisseau, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes d'exécution. C'est ainsi notamment que la forme et le nombre des emboítures pourraient être différents, l'essentiel étant que le jeu entre les emboítures mâles et femelles au niveau de l'intérieur du boisseau soit inférieur au jeu entre les emboítures mâles et femelles prévues plus à l'extérieur et destinées au logement du mortier.It goes without saying that the invention is not limited only to embodiments of this bushel, described above by way of examples, on the contrary, it embraces all variants of execution. This is how in particular that the shape and the number of sockets could be different, the main thing being that the play between the male sockets and females inside the bushel is less than the clearance between the male and female sockets provided more outside and intended for mortar housing.
