Abstract

The device has a stop positioned along a longitudinal direction, and a heating conductor placed in a thermal conductive protection cover including a cover zone and laterally spaced wings (12, 13). The stop is clutched by preformed walls (20, 21) whose lengths are higher that that of the stop in the longitudinal direction. The heating conductor is presented under the form of a double conductor. The walls respectively include folds passed towards the conductor and are perpendicular to a plane in which the wings are placed.

Description

La présente invention concerne un dispositif de câble chauffant électrique doté d'un conducteur chauffant disposé dans une enveloppe de protection thermoconductrice présentant une zone d'enveloppe et des ailes écartées latéralement ainsi qu'au moins une interruption dans la direction longitudinale.The present invention relates to an electric heating cable device having a heating conductor disposed in a thermally conductive protective envelope having an envelope area and laterally spaced wings and at least one interruption in the longitudinal direction.

Un dispositif de câble chauffant de ce type est par exemple connu d'après le document EP 0 369 915 B1 . Le dispositif de câble chauffant est utilisé pour former un chauffage par le sol. Le dispositif de câble chauffant est enrobé à cet effet dans une chape ou dans un autre couvre-sol. Le conducteur chauffant est alimenté en courant pendant le fonctionnement et se réchauffe. La chaleur est transmise à la chape par l'enveloppe de protection. Le dispositif de câble chauffant repose par les ailes sur le sous-plancher sur lequel a été appliquée la chape. L'interruption est prévue pour pouvoir guider le dispositif de câble chauffant non seulement le long d'une droite, mais aussi le long d'une courbe.A heating cable device of this type is for example known from the document EP 0 369 915 B1 . The heating cable device is used to form underfloor heating. The heating cable device is coated for this purpose in a screed or other groundcover. The heating conductor is energized during operation and warms up. The heat is transmitted to the screed by the protective envelope. The heating cable device rests by the wings on the subfloor on which the screed has been applied. The interruption is intended to guide the heating cable device not only along a line, but also along a curve.

On connaît un autre dispositif de câble chauffant d'après le document US 4 769 529 . La zone d'enveloppe est fendue ici. Afin de poser le dispositif de câble chauffant dans une courbe, les fentes doivent être prolongées de sorte qu'elles séparent également les ailes. Les ailes se chevauchent ensuite partiellement lorsque le dispositif de câble chauffant est posé en forme d'arc.Another heating cable device is known from the document US 4,769,529 . The envelope area is split here. In order to lay the heating cable device in a curve, the slots must be extended so that they also separate the wings. The wings then partially overlap when the heating cable device is arc-shaped.

Dans les deux cas, la pose n'est pas sans poser de problème. La séparation entraîne la formation d'arêtes vives qui peuvent endommager le conducteur chauffant dans certaines conditions défavorables. Il y a également un certain risque de blessure pour le monteur.In both cases, the pose is not without problems. Separation results in sharp edges that can damage the heating conductor under certain adverse conditions. There is also some risk of injury to the fitter.

Le but de l'invention est de garantir la protection du conducteur chauffant lors de la pose.The object of the invention is to guarantee the protection of the heating conductor during laying.

Ce but est atteint dans le cas d'un dispositif de câble chauffant électrique du type indiqué en introduction, par le fait que l'interruption est pontée par une paroi préformée dont la longueur est supérieure à celle de l'interruption dans la direction longitudinale.This object is achieved in the case of an electric heating cable device of the type indicated in the introduction, in that the interruption is bridged by a preformed wall whose length is greater than that of the interruption in the longitudinal direction.

La paroi préformée se raccorde à la zone d'enveloppe dont elle ne doit néanmoins pas suivre toute la périphérie. Etant donné que la paroi préformée est plus longue que l'interruption, elle peut être déformée relativement facilement. Cette paroi permet d'éviter une arête vive pouvant endommager le conducteur chauffant lorsque le dispositif de câble chauffant est guidé dans un tracé en forme d'arc.The preformed wall connects to the envelope area, but it must not follow the entire periphery. Since the preformed wall is longer than the interruption, it can be deformed relatively easily. This wall avoids a sharp edge that can damage the heating conductor when the heating cable device is guided in an arcuate pattern.

De préférence, la paroi présente au moins un pli tournant le dos au conducteur chauffant. Ce pli peut être à arêtes vives. Il peut néanmoins également présenter un passage arrondi. La formation de la paroi avec un pli permet d'obtenir une articulation dans laquelle la paroi peut se déformer lorsque le dispositif de câble chauffant est guidé en forme d'arc. Sur la face intérieure de l'arc, la paroi est ensuite pliée alors qu'elle est légèrement étirée sur la face extérieure de l'arc. Etant donné que la paroi présente une plus grande longueur que l'interruption, cela est aisément possible.Preferably, the wall has at least one fold turning the back to the heating conductor. This fold can be sharp-edged. It can nevertheless also have a rounded passage. The formation of the wall with a fold makes it possible to obtain a joint in which the wall can be deformed when the heating cable device is guided in the form of an arc. On the inner face of the arc, the wall is then folded while it is slightly stretched on the outer face of the arc. Since the wall has a greater length than the interruption, this is easily possible.

De préférence, la paroi est perpendiculaire à un plan dans lequel sont disposées les ailes. Cela facilite le guidage du dispositif de câble chauffant selon un arc. La paroi se déforme ensuite le long de la ligne arquée.Preferably, the wall is perpendicular to a plane in which the wings are arranged. This facilitates the guidance of the heating cable device in an arc. The wall then deforms along the arcuate line.

De préférence, la zone d'enveloppe présente une paroi latérale disposée, au moins dans un segment raccordé à l'interruption perpendiculaire à l'aile correspondante. On obtient ainsi une transition lisse entre la zone d'enveloppe et la paroi qui fait un pontage sur l'interruption.Preferably, the envelope zone has a lateral wall disposed, at least in a segment connected to the interruption perpendicular to the corresponding wing. This provides a smooth transition between the envelope area and the wall that bridges the gap.

De préférence, la paroi latérale est plane. Elle a donc un profil constant sur toute la longueur de l'enveloppe de protection. Cela facilite la production et permet d'éviter des imperfections.Preferably, the side wall is flat. It therefore has a constant profile over the entire length of the protective envelope. This facilitates production and avoids imperfections.

De préférence, l'aile se raccorde par un segment de transition à la paroi latérale, lequel segment est déformé vers l'intérieur en direction du conducteur chauffant. L'enveloppe de protection présente ainsi un profil en forme de Ω, permettant de supporter également le conducteur chauffant vers le bas. Le conducteur chauffant est ainsi maintenu de manière fiable dans l'enveloppe de protection. Le segment de transition est courbé en forme d'arc de manière appropriée afin d'empêcher des arêtes vives.Preferably, the wing is connected by a transition segment to the side wall, which segment is deformed inwardly towards the heating conductor. The protective casing thus has a profile in the form of Ω, to also support the heating conductor down. The heating conductor is thus reliably held in the protective casing. The transition segment is arcuate curved appropriately to prevent sharp edges.

De préférence, la zone d'enveloppe est sensiblement réalisée sous forme de profil rectangulaire. Un profil rectangulaire peut être fabriqué simplement et peut être relié à la paroi. La notion de « rectangle » n'est pas ici à prendre au sens mathématique strict. Des coins arrondis du profil sont possibles. Il est également possible que les parois divergent légèrement.Preferably, the envelope zone is substantially formed as a rectangular profile. A rectangular profile can be made simply and can be connected to the wall. The notion of "rectangle" is not here to be taken in the strict mathematical sense. Rounded corners of the profile are possible. It is also possible that the walls diverge slightly.

On préfère ici que le conducteur chauffant présente une coupe transversale ronde, de sorte qu'il forme plusieurs sections de contact avec la zone d'enveloppe. Plusieurs sections de contact conçues de manière linéaire suffisent à la transmission de la chaleur du conducteur chauffant à l'enveloppe de protection. Dans la pratique, les sections de contact présentent également une certaine largeur de sorte qu'une surface suffisante est disponible pour le passage de la chaleur.It is preferred here that the heating conductor has a round cross section, so that it forms a plurality of contact sections with the envelope area. Several linearly designed contact sections are sufficient for the transmission of heat from the heating conductor to the protective jacket. In practice, Contact sections also have a certain width so that a sufficient area is available for the passage of heat.

Le conducteur chauffant est réalisé de préférence en tant que conducteur double.
Il peut ainsi remplir correctement la coupe transversale libre d'un profil rectangulaire.The heating conductor is preferably made as a double conductor.
It can thus correctly fill the free cross section of a rectangular profile.

De préférence, la déformation est continue. Une « force de serrage » constante s'exerce ainsi sur le conducteur chauffant. Une surface continue dans laquelle la chaleur peut passer du conducteur chauffant à l'enveloppe de protection est également disponible.Preferably, the deformation is continuous. A constant "clamping force" is thus exerted on the heating conductor. A continuous surface in which heat can pass from the heating conductor to the shroud is also available.

Dans le cas d'un dispositif de câble chauffant du type indiqué en introduction pouvant également présenter une ou plusieurs des caractéristiques susmentionnées, au moins une aile présente au moins un élément de fixation, dont la base est reliée à l'aile et est flexible depuis le plan de l'aile. Cet élément de fixation peut également être prévu dans le cas d'un dispositif de câble chauffant pour lequel l'interruption n'est pas pontée par la paroi.In the case of a heating cable device of the type indicated in the introduction which may also have one or more of the above-mentioned characteristics, at least one wing has at least one fixing element, the base of which is connected to the wing and is flexible since the plane of the wing. This fixing element can also be provided in the case of a heating cable device for which the interruption is not bridged by the wall.

Lors du montage du dispositif de câble chauffant, l'enveloppe de protection doit être fixée sur le plancher (ou à une paroi ou un plafond). A cet effet, on utilise habituellement des agrafes qui traversent les ailes et qui sont enfoncées dans le sous-plancher. Ces agrafes sont fréquemment perdues ou ne sont pas disponibles en nombre suffisant. Dans de nombreux cas, l'installateur a également du mal à déterminer l'endroit où il doit placer une agrafe pour garantir une fixation fiable. Si on place désormais dès le départ l'élément de fixation sur l'aile, ce problème est résolu. L'aile est formée à partir d'une matière plane, par exemple d'une tôle métallique. On peut désormais prévoir dans le plan de cette aile l'élément de fixation de manière à ce qu'il ne soit pas davantage gêné lors du transport. Lorsque l'élément de fixation doit être utilisé, il est plié simplement à partir du plan de l'aile, par exemple à angle droit vers le bas. Lors du montage du dispositif de câble chauffant, il peut ensuite être entraîné directement dans le sous-plancher.When mounting the heating cable device, the enclosure must be attached to the floor (or wall or ceiling). For this purpose, staples that pass through the wings and are pushed into the subfloor are usually used. These staples are frequently lost or are not available in sufficient numbers. In many cases, the installer also has difficulty determining where to place a clip to ensure reliable fastening. If we now place the fastening element on the wing from the start, this problem is solved. The wing is formed from a flat material, for example a metal sheet. It is now possible to provide in the plane of this wing the fastening element so that it is not further hampered during transport. When the fastener is to be used, it is simply folded from the plane of the wing, for example at a right angle downward. When mounting the heating cable device, it can then be driven directly into the subfloor.

Il est ici préférable que l'élément de fixation soit entouré par une zone de séparation, séparant l'élément de fixation de l'aile, sur au moins la moitié de sa périphérie. L'élément de fixation est donc disposé par la surface à l'intérieur de l'aile de manière à ne pas gêner davantage lors du transport. La zone de séparation peut également être conçue sous forme de ligne. Il est néanmoins également possible de concevoir la zone de séparation en tant qu'intervalle clairement identifiable entre l'élément de fixation et le reste de l'aile.It is preferable here that the fastening element is surrounded by a separation zone, separating the fastening element from the wing, on at least half of its periphery. The fastening element is thus disposed by the surface inside the wing so as not to interfere further during transport. The separation zone can also be designed as a line. It is nevertheless also possible to design the separation zone as a clearly identifiable gap between the fastening element and the rest of the wing.

La zone de séparation est de préférence estampée, emboutie ou poinçonnée.
L'emboutissage est un procédé relativement simple pour créer l'élément de fixation.The separation zone is preferably stamped, stamped or stamped.
Stamping is a relatively simple process for creating the fastener.

De préférence, l'élément de fixation présente une pointe et une tige qui se termine à la base, la pointe présentant une largeur supérieure à la tige. On peut ensuite utiliser la pointe en tant qu'ardillon ce qui permet d'empêcher l'élément de fixation de se détacher du fond. Dans de nombreux cas, le fond ou le sous-plancher sur lequel est monté le dispositif de câble chauffant est formé par une mousse devant assurer par ailleurs une isolation vers le bas. L'élément de fixation peut être légèrement enfoncé dans cette mousse synthétique pouvant exister sous forme de plaques.Preferably, the fastener has a tip and a shank that terminates at the base, the tip having a width greater than the shank. The tip can then be used as an abutment to prevent the fastener from becoming detached from the bottom. In many cases, the bottom or subfloor on which the heating cable device is mounted is formed by a foam to further provide insulation downwards. The fastener may be slightly sunken into this synthetic foam which may exist in the form of plates.

Il est ici particulièrement privilégié que la pointe présente un profil de crochet.
La pointe peut ensuite s'accrocher dans le sous-plancher ce qui permet d'améliorer encore davantage la fixation.It is particularly privileged here that the tip has a hook profile.
The tip can then hook into the subfloor which further improves the attachment.

De manière préférée, la pointe et/ou la tige présente(nt) une ouverture de passage. Ceci est aussi une mesure pour améliorer la fixation. Dans l'ouverture, on peut introduire une matière du sous-plancher, par exemple lorsqu'une chape est appliquée sur une mousse synthétique.Preferably, the tip and / or the rod has (s) a passage opening. This is also a measure to improve fixation. In the opening, it is possible to introduce a subfloor material, for example when a screed is applied to a synthetic foam.

De préférence, l'élément de fixation peut être plié à partir de l'aile autour d'une ligne de pliage qui est orientée sensiblement perpendiculairement au conducteur chauffant. Dans le cas d'une largeur limitée des ailes, des longueurs suffisantes peuvent ainsi être obtenues pour l'élément de fixation.Preferably, the fastener may be folded from the flange about a fold line that is oriented substantially perpendicular to the heating conductor. In the case of a limited width of the wings, sufficient lengths can thus be obtained for the fixing element.

L'enveloppe de protection présente de préférence un segment rectiligne dans lequel l'aile est réalisée en continu et la zone d'enveloppe est interrompue au moins une fois. Dans de nombreux cas, un chauffage par le sol se compose de plusieurs segments rectilignes reliés entre eux par des segments arqués. On peut ensuite utiliser le segment rectiligne de l'enveloppe de protection pour les segments rectilignes. Lorsque des modifications de direction devraient néanmoins être requises ici, on peut les effectuer là où la zone d'enveloppe est interrompue, c'est-à-dire là où elle présente un intervalle. Le cas échéant, on doit alors encore séparer et/ou traverser l'aile dans la zone de l'intervalle.The protective envelope preferably has a rectilinear segment in which the wing is made continuously and the envelope area is interrupted at least once. In many cases, underfloor heating consists of several straight segments interconnected by arcuate segments. The rectilinear segment of the protective envelope can then be used for the rectilinear segments. Where changes of direction should nevertheless be required here, they may be made where the envelope zone is interrupted, ie where it has an interval. If necessary, then we must still separate and / or cross the wing in the area of the gap.

Un dispositif de câble chauffant 1, tel qu'il est représenté sur la Fig. 1, présente un segment rectiligne 2 aux deux extrémités duquel se rattache respectivement un segment arqué 3, 4. On peut élargir ce dispositif de câble chauffant quasiment à l'infini en raccordant un autre segment rectiligne 2 à un segment arqué ou aux deux 3, 4 et en y raccordant à nouveau un segment arqué 3, 4, etc. Le dispositif de câble chauffant sert à former un segment électrique d'un chauffage par le sol. A cet effet, le dispositif de câble chauffant est posé sur un sous-plancher et y est fixé tel que l'explique la description ci-dessous en association avec la Fig. 6. Une chape ou un autre revêtement recouvrant également le dispositif de câble chauffant 1 est appliqué ensuite sur le sous-plancher pouvant être formé par exemple de plaques isolantes.A heating cable device 1, as shown in FIG. Fig. 1 , presents a rectilinear segment 2 at both ends of which an arcuate segment 3, 4 is respectively attached. This heating cable device can be expanded almost infinitely by connecting another rectilinear segment 2 to an arcuate segment or to both of them 3, 4 and again connecting an arcuate segment 3, 4, and so on. The heating cable device serves to form an electrical segment of underfloor heating. For this purpose, the heating cable device is placed on a subfloor and is fixed as explained in the description below in association with the Fig. 6 . A screed or other covering also covering the heating cable device 1 is then applied to the subfloor which may be formed for example of insulating plates.

Afin de pouvoir fabriquer les segments arqués 3, 4, le dispositif de câble chauffant présente plusieurs segments 5, 6 entre lesquels est disposée une interruption. Un autre segment de ce type est décrit sur les Figs. 4 et 5, la Fig. 4 étant un premier mode de réalisation et la Fig. 5 un deuxième mode de réalisation.In order to be able to manufacture the arcuate segments 3, 4, the heating cable device has a plurality of segments 5, 6 between which an interruption is arranged. Another segment of this type is described on the Figs. 4 and 5 , the Fig. 4 being a first embodiment and the Fig. 5 a second embodiment.

Le segment présente une zone d'enveloppe 8 avec deux parois latérales 9, 10 et un plafond 11. Une aile 12, 13 se raccorde à chaque paroi latérale 9, 10, un segment de transition 14 étant disposé entre l'aile 12 et la paroi latérale 9, et un segment de transition 15 étant disposé entre l'aile 13 et la paroi latérale 10. Les segments de transition 14, 15 sont légèrement courbés en demi-cercle et font saillie dans une zone comprise entre les deux parois latérales 9, 10. La zone d'enveloppe 8 présente donc un profil sensiblement rectangulaire qui entoure une cavité 16 dans laquelle sont disposés des conducteurs chauffants 17. Les conducteurs chauffants 17 sont entourés par une isolation 18 qui isole le conducteur chauffant 17 respectivement électriquement du segment 5, mais permet une conduction thermique du conducteur chauffant 17 au segment 5. Un caloduc correspondant est naturellement également disponible dans le segment rectiligne 2 et dans les autres segments 5, 6. Les conducteurs chauffants 17 forment un conducteur double qui remplit la coupe transversale de la zone d'enveloppe 8. On peut également utiliser un conducteur ovale ou rectangulaire. Un conducteur double peut être légèrement recourbé lorsque les deux conducteurs chauffants sont disposés l'un sur l'autre.The segment has an envelope zone 8 with two side walls 9, 10 and a ceiling 11. A wing 12, 13 is connected to each side wall 9, 10, a transition segment 14 being disposed between the wing 12 and the side wall 9, and a transition segment 15 being disposed between the flange 13 and the side wall 10. The transition segments 14, 15 are slightly curved in a semicircle and project in an area between the two side walls 9 10. The envelope zone 8 thus has a substantially rectangular profile which surrounds a cavity 16 in which heating conductors 17 are arranged. The heating conductors 17 are surrounded by an insulation 18 which isolates the heating conductor 17 respectively electrically from the segment 5, but allows thermal conduction of the heating conductor 17 to the segment 5. A corresponding heat pipe is naturally also available in the straight segment 2 and in the other segments 5, 6. The heating conductors 17 form a double conductor that fills the cross section of the envelope zone 8. It is also possible to use an oval or rectangular conductor. A double conductor may be slightly curved when the two heating conductors are arranged one on the other.

Le contact entre les conducteurs chauffants 17 via l'isolation 18 avec les parois latérales 9, 10 et le plafond 11 ainsi qu'avec les deux segments de transition 14, 15 s'effectue pratiquement le long d'une ligne qui a naturellement une certaine largeur. Un contact linéaire de ce type suffit néanmoins à permettre une transmission de chaleur suffisante entre le conducteur chauffant 17 et le segment 5.The contact between the heating conductors 17 via the insulation 18 with the side walls 9, 10 and the ceiling 11 and with the two transition segments 14, 15 is practically along a line which naturally has a certain width. A linear contact of this type is nevertheless sufficient to allow sufficient heat transfer between the heating conductor 17 and the segment 5.

Pour le montage, le profil 5 peut être légèrement courbé au niveau de son extrémité ouverte. En d'autres termes, les segments de transition 14, 15 sont légèrement espacés l'un de l'autre. Le conducteur chauffant 17 peut alors être posé. Lorsqu'on laisse les deux segments de transition 14, 15 et/ou les parois latérales 9, 10 revenir élastiquement dans leur position initiale, le conducteur chauffant 17 est maintenu dans le profil 5.For mounting, the profile 5 can be slightly curved at its open end. In other words, the transition segments 14, 15 are slightly spaced apart from each other. The heating conductor 17 can then be laid. When the two transition segments 14, 15 and / or the side walls 9, 10 are allowed to spring back to their initial position, the heating conductor 17 is held in the profile 5.

La Fig. 5 illustre un mode de réalisation modifié du segment 5 correspondant à celui de la Fig. 4. Une différence essentielle consiste en ce que seul un conducteur chauffant 17 est prévu. Dans ce cas, on peut bloquer le conducteur chauffant 17 entre les deux parois latérales 9, 10 de manière à ce qu'il soit comprimé contre le plafond, et ainsi une transmission de chaleur suffisante est également garantie du conducteur chauffant 17 au segment 5.The Fig. 5 illustrates a modified embodiment of segment 5 corresponding to that of the Fig. 4 . An essential difference is that only a heating conductor 17 is provided. In this case, it is possible to block the heating conductor 17 between the two side walls 9, 10 so that it is compressed against the ceiling, and thus a sufficient heat transmission is also guaranteed from the heating conductor 17 to the segment 5.

Le conducteur chauffant 17 présente une coupe transversale circulaire. C'est une solution très économique pour fabriquer le conducteur chauffant 17. Il est néanmoins également possible d'envisager d'autres coupes transversales, par exemple une coupe transversale rectangulaire adaptée au contour de la cavité 16.The heating conductor 17 has a circular cross section. It is a very economical solution to manufacture the heating conductor 17. It is nevertheless also possible to envisage other cross sections, for example a rectangular cross section adapted to the contour of the cavity 16.

Comme on peut le voir notamment sur les Figs. 2 et 3 (on ne peut pas y voir le conducteur chauffant 17), l'interruption 7 interrompant également les ailes 12, 13 est pontée par respectivement une paroi 20, 21. La paroi 20, 21 présente respectivement une longueur supérieure à celle de l'interruption 7 dans la direction longitudinale. La direction longitudinale est la direction dans laquelle s'étend le conducteur chauffant. Chaque paroi 20, 21 présente un pli 22, 23. La paroi 20, 21 est donc respectivement préformée. Elle se raccorde également aux segments 5, 6 par un coude, de sorte que les coudes et les plis 22, 23 forment pour ainsi dire des articulations au niveau desquelles une déformation de la paroi respective 20, 21 est facilitée.As can be seen in particular on Figs. 2 and 3 (It is not possible to see the heating conductor 17), the interruption 7 also interrupting the wings 12, 13 is bridged by a wall 20, 21, respectively. The wall 20, 21 has a length greater than that of the interruption respectively. 7 in the longitudinal direction. The longitudinal direction is the direction in which the heating conductor extends. Each wall 20, 21 has a fold 22, 23. The wall 20, 21 is respectively preformed. It is also connected to the segments 5, 6 by a bend, so that the bends and the folds 22, 23 form, so to speak, joints at which a deformation of the respective wall 20, 21 is facilitated.

Lorsqu'on modifie alors l'orientation angulaire de deux segments 5, 6 l'un par rapport à l'autre, comme le montrent par exemple les Figs. 2 et 3, la paroi 21 intérieure à la courbe est légèrement écrasée ou davantage repliée et la paroi 20 extérieure à la courbe est légèrement allongée ou dépliée de manière à ce que le revêtement latéral du conducteur chauffant soit également garanti dans l'interruption. Les parois 20, 21 se raccordent aux segments 5, 6. On empêche ainsi des arêtes vives qui pourraient endommager l'isolation 18 du conducteur chauffant 17 ou le conducteur chauffant 17 à proprement parler. Comme on peut le voir sur les Figs. 4 et 5, les parois 20, 21 sont perpendiculaires à un plan dans lequel sont disposées les ailes 12, 13. Les parois 20, 21 font saillie latéralement vers l'extérieur, c'est-à-dire s'écartent du conducteur chauffant 17.When the angular orientation of two segments 5, 6 is then changed with respect to each other, as shown, for example, by Figs. 2 and 3 the wall 21 inside the curve is slightly crushed or further folded and the outer wall of the curve is slightly elongated or unfolded so that the side coating of the heating conductor is also guaranteed in the interruption. The walls 20, 21 are connected to the segments 5, 6. This prevents sharp edges that could damage the insulation 18 of the heating conductor 17 or the heating conductor 17 itself. As can be seen on the Figs. 4 and 5 , the walls 20, 21 are perpendicular to a plane in which the flanges 12, 13 are arranged. The walls 20, 21 project laterally outwards, that is to say away from the heating conductor 17.

Le profil du segment rectiligne 2 correspond à celui des segments 5, 6, c'est-à-dire que le segment rectiligne 2 présente également deux ailes 12, 13 et une zone d'enveloppe 8.The profile of the rectilinear segment 2 corresponds to that of the segments 5, 6, that is to say that the rectilinear segment 2 also has two wings 12, 13 and an envelope zone 8.

Comme on peut le voir sur la Fig. 1, plusieurs éléments de fixation 24, que l'on peut mieux voir dans la représentation agrandie de la Fig. 6, sont placés dans les ailes 12, 13.As can be seen on the Fig. 1 , several fixing elements 24, which can be better seen in the enlarged representation of the Fig. 6 , are placed in the wings 12, 13.

Chaque élément de fixation présente une base 25 reliée à l'aile 12. A la liaison s'étend une ligne de pliage 26, au niveau de laquelle l'élément de fixation 24 peut être plié à partir du plan de l'aile 12, de manière préférée vers le bas, c'est-à-dire en s'écartant de la zone d'enveloppe 8. La ligne de pliage 26 s'étend ici sensiblement perpendiculairement à la direction longitudinale du conducteur chauffant 17. Lorsqu'on prévoit une deuxième ligne de pliage 19 au milieu de l'élément de fixation 24, alors on peut replier également vers le haut l'élément de fixation 24 à la première ligne de pliage 26 et dans la direction opposée à la deuxième ligne de pliage 19, avant de poser le dispositif de conducteur chauffant. Une pression exercée sur l'élément de fixation 24 faisant saillie vers le haut permet de l'introduire ensuite dans une sous-couche.Each fastening element has a base 25 connected to the wing 12. At the connection extends a fold line 26, at which the fastening element 24 can be folded from the plane of the wing 12, preferably downwardly, that is to say away from the envelope zone 8. The fold line 26 extends here substantially perpendicular to the longitudinal direction of the heating conductor 17. When expected a second fold line 19 in the middle of the fastening element 24, so that the fastening element 24 can also be folded up to the first fold line 26 and in the opposite direction to the second fold line 19, before installing the heating conductor device. Pressure exerted on the fastening element 24 projecting upwards then makes it possible to introduce it into an underlayer.

La base 25 est formée par une zone d'une tige 27 de l'élément de fixation 24, qui est à proximité de la ligne de pliage 26. Sur le côté de la tige opposé à la ligne de pliage 26, est placée une pointe 28 dotée de deux ardillons 29, 30, c'est-à-dire présentant un profil de crochet.The base 25 is formed by an area of a rod 27 of the fastener 24, which is close to the fold line 26. On the side of the rod opposite the line of folding 26, is placed a point 28 with two barbs 29, 30, that is to say having a hook profile.

Une zone de séparation 31, formée en tant que zone de dégagement et pouvant par exemple être perforée par estampage, poinçonnage ou emboutissage, se trouve entre l'aile 12 et l'élément de fixation 24, en dehors de la ligne de pliage 26. La zone de séparation 31 peut également être formée par une ligne. Mais, il est plus approprié de prévoir un certain intervalle pour qu'un monteur puisse plus facilement accéder à l'élément de fixation 24 afin de pouvoir le plier à partir de l'aile 12.A separation zone 31, formed as a clearance zone and capable of being perforated by stamping, punching or stamping, is located between the wing 12 and the fastening element 24, outside the fold line 26. The separation zone 31 may also be formed by a line. But, it is more appropriate to provide a certain interval so that an assembler can more easily access the fastening element 24 in order to be able to bend it from the wing 12.

La pointe 28 présente une plus grande largeur que la tige 27, de sorte que la pointe 28 peut s'accrocher dans un fond, par exemple dans une plaque isolante, lorsque le dispositif de câble chauffant est posé sur la sous-couche.The tip 28 has a greater width than the rod 27, so that the tip 28 can catch in a bottom, for example in an insulating plate, when the heating cable device is placed on the underlayer.

La pointe 28 de l'élément de fixation et la tige 27 peuvent présenter des ouvertures de passage 33, 34. Dans ces ouvertures de passage 33, 34, on peut insérer de la matière du fond lorsqu'elle convient à cet usage. Dans ce cas, la capacité de retenue des éléments de fixation 24 est encore améliorée.The tip 28 of the fastener and the rod 27 may have through-holes 33, 34. In these through-openings 33, 34, bottom material may be inserted when suitable for this purpose. In this case, the retaining capacity of the fasteners 24 is further improved.

Des éléments de fixation 24 correspondants peuvent bien évidemment être également prévus dans les ailes 12, 13 des segments 5, 6.Corresponding fasteners 24 may of course also be provided in the wings 12, 13 of the segments 5, 6.

Comme on peut le voir par ailleurs sur la Fig. 1, le segment rectiligne 2 présente un intervalle 32 dans une position dans laquelle les ailes 12, 13 sont conçues en continu comme on peut le voir sur la Fig. 7. Dans certains cas, il faut procéder à de légères corrections de direction dans le segment rectiligne 2. Dans ce cas, on peut séparer, par exemple découper, les ailes 12, 13 ou une des ailes 12, 13 et plier ensuite légèrement le segment rectiligne 2.As can be seen elsewhere on the Fig. 1 the rectilinear segment 2 has a gap 32 in a position in which the wings 12, 13 are continuously designed as can be seen in FIG. Fig. 7 . In some cases, it is necessary to make slight steering corrections in the rectilinear segment 2. In this case, it is possible to separate, for example cut, the wings 12, 13 or one of the wings 12, 13 and then slightly bend the rectilinear segment. 2.

Plusieurs intervalles de ce type, par exemple à une distance de 30 à 50 mm, peuvent également être prévus, d'une manière non représentée.Several such gaps, for example at a distance of 30 to 50 mm, may also be provided, in a manner not shown.

On peut prévoir, de manière également non représentée, de numéroter les différents segments 2 ou de les pourvoir d'un autre repérage. Une numérotation de ce type permet à l'installateur de poser plus facilement le dispositif de câble chauffant d'une manière prévue.It is also possible, not shown, to number the different segments 2 or to provide them with another location. Such a numbering makes it easier for the installer to install the heating cable device in a planned manner.

Un dispositif de câble chauffant 1 est habituellement livré d'un seul bloc sur le chantier, les différents segments parallèles 2 étant reliés les uns aux autres par des rubans adhésifs. Un installateur doit alors séparer les rubans adhésifs à certains endroits pour obtenir différents segments qu'il pourra poser dans la pièce. Une numérotation permet à l'installateur de décider plus facilement de l'endroit où il doit séparer les rubans adhésifs.A heating cable device 1 is usually delivered as a single unit on site, the different parallel segments 2 being connected to each other by adhesive tapes. An installer must then separate the adhesive tapes at certain locations to obtain different segments that he can put in the room. A numbering makes it easier for the installer to decide where to separate the adhesive tapes.

Le repérage des différents segments se fait de préférence sur les ailes 12, 13 de manière à ce que les numéros ou les repérages soient clairement visibles. On peut poinçonner ou frapper par exemple les repérages. On peut également les imprimer. Dans chaque cas, on peut établir un lien direct avec un schéma de montage grâce à la numérotation ou au repérage. L'installateur peut ainsi s'orienter plus facilement.The identification of the different segments is preferably done on the wings 12, 13 so that the numbers or the marks are clearly visible. One can punch or hit for example the markings. They can also be printed. In each case, it is possible to establish a direct link with an assembly diagram by means of numbering or marking. The installer can thus orient himself more easily.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation ci-dessus décrits et représentés, à partir desquels on pourra prévoir d'autres modes et d'autres formes de réalisation, sans pour autant sortir du cadre de l'invention.Of course, the invention is not limited to the embodiments described above and shown, from which we can provide other modes and other embodiments, without departing from the scope of the invention. .
