Definitions
- the present invention relates to electric heating cables with heat diffuser and, more particularly, to prefabricated networks formed with such cables.
- Electric heating cables with heat diffusing tape are described in document EP-A-225 835.
- the tape a good conductor of heat, has a longitudinal groove in which is housed and maintained the electric cable which is in intimate contact with the internal face of the throat of the ribbon.
- This one has regularly spaced transverse slots, which give the whole a certain flexibility and allow its winding on a reel.
- the slots constitute sorts of pre-cuts that the cable installer can finish to allow rotations in the general plane of the ribbon.
- the cable provided with its ribbon is placed in successive parallel segments by making it perform a 180 ° change of direction at the ends of each segment.
- Direction change bends are made on site by cutting parts of the edges of the tape near the slots in the affected areas.
- transverse metal strips on which the segments are stapled as and when they are laid It therefore takes appreciable time to equip a surface. For example, to equip a 40 m2 room, it takes between two and three hours.
- An object of the present invention to provide a network arrangement of a ribbon diffuser cable to facilitate installation and make it significantly faster.
- Claim 1 attached, indicates how this object, as well as others, is achieved and shows a configuration characteristic of the invention.
- the electric heating cable with heat diffusing tape of FIG. 1 is in the form of a sinuous line with parallel rectilinear segments connected by rounded elbows.
- the sinuous line is formed by a series of identical cycles, where each cycle comprises a rectilinear segment 1a, followed by a bend 2a in the shape of a semicircle, followed by a segment 1b, - even followed by a bend 2b in the shape of a semicircle.
- the rectilinear segments 1a and 1b are parallel and equal.
- the concavity of the elbow 2a is opposite to that of the elbow 2b.
- the diameter of the semicircles of the elbows 2a and 2b defines the distance between the straight segments 1a and 1b.
- Figs. 1 and 2 the cable of the invention is shown seen from above, which means that we see the back of the diffuser tape, with a central part enclosing more than 180 ° of the electric cable 3, and two side wings which lie on a plane before wrapping the cable.
- the diffusing tape is, all along, in one piece, with simply its ends cut, not perpendicular to the general direction of the segment, but at an angle such that the edges of the two wings of the ribbon make an angle less than 180 °.
- the wings of the ribbon are notched so as to form, in the example described, six sections each comprising a back 4 and wings 5a and 5b.
- Each wing, such as 5a has a general isosceles trapezoidal shape, with the small base on the outside and the large base on the inside, near the electric cable 3.
- the angle made, with the axis of symmetry of the trapezoid, the lateral sides of the trapezium is around 20 °. It will be noted that, in the case where there are six sections in a bend, this angle must be greater than 15 ° to avoid, inside the bend, the systematic superpositions of wings of adjacent sections.
- Fig. 2 also shows that, under the large base, each wing is extended inward by a rectangular part, that is to say whose edges are perpendicular to the electric cable.
- Fig. 3 shows that between two successive sections, a notch between two wings extends along the lateral part of the ribbon, up to about halfway up the electrical cable 3, the back 4 of the ribbon not being cut. As a result, by its back 4, the ribbon remains uninterrupted, whether on the straight segments or on the elbows. In this way, the cable 3 is never stripped up and the ribbon continues to fully play its role as a heat diffuser, even in the elbows, avoiding any hotter point.
- the straps 6 and 7 are inextensible. They can be, for example, made up of two ribbons of resistant plastic material glued one against the other between the segments, and the two faces of the rectilinear segments being respectively glued one under the upper ribbon and the other on the lower ribbon.
- Small holes such as 8, can be punched in the wings of the tape, to allow the installation of thumbtacks, the rod of which hangs in the insulating layer below the cable, after the cable has been laid.

Abstract
Description
La présente invention concerne des câbles électriques chauffants à diffuseur de chaleur et, plus particulièrement, des réseaux préfabriqués formés avec de tels câbles.The present invention relates to electric heating cables with heat diffuser and, more particularly, to prefabricated networks formed with such cables.
Des câbles électriques chauffants à ruban diffuseur de chaleur sont décrits dans le document EP-A-225 835. Dans ce document, le ruban, bon conducteur de la chaleur, présente une gorge longitudinale dans laquelle est logé et maintenu le câble électrique qui est en contact intime avec la face interne de la gorge du ruban. Celui-ci présente des fentes transversales, régulièrement espacées, qui donnent à l'ensemble une certaine souplesse et permettent son enroulement sur un touret. Par ailleurs, les fentes constituent des sortes de prédécoupes que le poseur de câble peut terminer pour permettre d'effectuer des rotations dans le plan général du ruban.Electric heating cables with heat diffusing tape are described in document EP-A-225 835. In this document, the tape, a good conductor of heat, has a longitudinal groove in which is housed and maintained the electric cable which is in intimate contact with the internal face of the throat of the ribbon. This one has regularly spaced transverse slots, which give the whole a certain flexibility and allow its winding on a reel. In addition, the slots constitute sorts of pre-cuts that the cable installer can finish to allow rotations in the general plane of the ribbon.
Pour équiper une plancher chauffant, on dispose le câble muni de son ruban en segments parallèles successifs en lui faisant effectuer aux extrémités de chaque segment un changement de direction à 180°. Les coudes de changement de direction sont réalisés sur le chantier en découpant des parties des bords du ruban au voisinage des fentes dans les zones concernées. Par ailleurs, pour maintenir les segments parallèles pendant la pose, il faut prévoir transversalement des bandes métalliques sur lesquelles on agrafe les segments au fur et à mesure de leurs poses. Il faut donc un temps appréciable pour équiper une surface. A titre d'exemple, pour équiper une pièce de 40 m², il faut entre deux et trois heures.To equip a heated floor, the cable provided with its ribbon is placed in successive parallel segments by making it perform a 180 ° change of direction at the ends of each segment. Direction change bends are made on site by cutting parts of the edges of the tape near the slots in the affected areas. Furthermore, to keep the segments parallel during installation, it is necessary to provide transverse metal strips on which the segments are stapled as and when they are laid. It therefore takes appreciable time to equip a surface. For example, to equip a 40 m² room, it takes between two and three hours.
Le document US-A-3 209 128 décrit un câble chauffant conformé en ligne sinueuse dont chaque cycle comprend un coude dans un premier sens, suivi d'un premier segment rectiligne, suivi d'un coude, dans le second sens, suivi d'un second segment rectiligne, les cycles étant connexes et le câble électrique proprement dit étant ininterrompu.Document US-A-3,209,128 describes a heating cable shaped as a sinuous line, each cycle of which comprises a bend in a first direction, followed by a first rectilinear segment, followed by a bend in the second direction, followed by a second rectilinear segment, the cycles being connected and the electric cable proper being uninterrupted.
Un objet de la présente invention consiste à prévoir un arrangement en réseau d'un câble à diffuseur en ruban permettant de faciliter la pose et de la rendre sensiblement plus rapide.An object of the present invention to provide a network arrangement of a ribbon diffuser cable to facilitate installation and make it significantly faster.
La revendication 1, ci-jointe, indique comment sont atteints cet objet, ainsi que d'autres, et fait apparaître une configuration caractéristique de l'invention. Les revendications dépendantes, également jointes, font apparaître d'autres caractéristiques d'exemples de réalisation de l'invention.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront 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:
- la Fig. 1 est une vue de dessus d'une portion d'un réseau de câbles chauffants préfabriqué suivant l'invention,
- la Fig. 2 est une vue de dessus, à plus grande échelle, de la structure d'un coude du réseau de la Fig. 1, et
- la Fig. 3 est une vue de côté d'une partie du coude de la Fig. 2.
- Fig. 1 is a top view of a portion of a network of prefabricated heating cables according to the invention,
- Fig. 2 is a top view, on a larger scale, of the structure of an elbow of the network of FIG. 1, and
- Fig. 3 is a side view of part of the elbow of FIG. 2.
Le câble électrique chauffant à ruban diffuseur de chaleur de la Fig. 1 se présente sous la forme d'une ligne sinueuse avec des segments rectilignes parallèles reliés par des coudes arrondis. En pratique, on peut considérer que la ligne sinueuse est formée d'une suite de cycles identiques, où chaque cycle comprend un segment rectiligne 1a, suivi d'un coude 2a en forme de demi-cercle, suivi d'un segment 1b, lui-même suivi d'un coude 2b en forme de demi-cercle. Les segments rectilignes 1a et 1b sont parallèles et égaux. La concavité du coude 2a est inverse de celle du coude 2b. Le diamètre des demi-cercles des coudes 2a et 2b définit la distance entre les segments rectilignes 1a et 1b.The electric heating cable with heat diffusing tape of FIG. 1 is in the form of a sinuous line with parallel rectilinear segments connected by rounded elbows. In practice, we can consider that the sinuous line is formed by a series of identical cycles, where each cycle comprises a
Aux Figs. 1 et 2, le câble de l'invention est représenté vu de dessus, ce qui veut dire que l'on voit le dos du ruban diffuseur, avec une partie centrale enserrant plus de 180° du câble électrique 3, et deux ailes latérales qui reposent sur un plan avant l'enrobage du câble.In Figs. 1 and 2, the cable of the invention is shown seen from above, which means that we see the back of the diffuser tape, with a central part enclosing more than 180 ° of the
Dans les segments rectilignes 1a et 1b, le ruban diffuseur est, tout du long, d'une seule pièce, avec simplement ses extrémités coupées, non perpendiculairement à la direction générale du segment, mais suivant un angle tel que les bords des deux ailes du ruban fassent un angle inférieur à 180°.In the
Dans les coudes 2a et 2b, comme le montre mieux la Fig. 2, les ailes du ruban sont encochées de manière à former, dans l'exemple décrit, six tronçons comportant chacun un dos 4 et des ailes 5a et 5b. Chaque aile, telle que 5a, a une forme générale trapézoïdale isocèle, avec la petite base à l'extérieur et la grande base à l'intérieur, près du câble électrique 3. L'angle que font, avec l'axe de symétrie du trapèze, les côtés latéraux du trapèze est de l'ordre de 20°. On notera que, dans le cas où il y a six tronçons dans un coude, cet angle doit être supérieur à 15° pour éviter, à l'intérieur du coude, les superpositions systématiques d'ailes de tronçons adjacents.In the
La Fig. 2 fait également apparaître que, sous la grande base, chaque aile est prolongée vers l'intérieur par une partie rectangulaire, c'est-à-dire dont les bords sont perpendiculaires au câble électrique. La Fig. 3 montre qu'entre deux tronçons successifs, une encoche entre deux ailes se prolonge le long de la partie latérale du ruban, jusqu'à mi-hauteur environ du câble électrique 3, le dos 4 du ruban n'étant pas découpé. Il en résulte que, par son dos 4, le ruban reste ininterrompu que ce soit sur les segments droits ou sur les coudes. De cette manière, le câble 3 n'est jamais dénudé vers le haut et le ruban continue à jouer totalement son rôle de diffuseur de chaleur, même dans les coudes, en évitant tout point plus chaud.Fig. 2 also shows that, under the large base, each wing is extended inward by a rectangular part, that is to say whose edges are perpendicular to the electric cable. Fig. 3 shows that between two successive sections, a notch between two wings extends along the lateral part of the ribbon, up to about halfway up the
Comme le montre encore la Fig. 1, deux lanières 6, perpendiculaires aux segments rectilignes 1a et 1b, sont accrochées auxdits segments. Les lanières 6 et 7 s'étendent sur l'ensemble de la ligne sinueuse du câble. Les points d'attache des lanières aux segments sont espacés d'une distance égale au diamètre d'un coude 2a ou 2b, de manière à maintenir les segments rectilignes parallèles. En pratique, les lanières 6 et 7 sont inextensibles. Elles peuvent être, par exemple, constituées de deux rubans en matière plastique résistante collés l'un contre l'autre entre les segments, et les deux faces des segments rectilignes étant respectivement collées l'une sous le ruban supérieur et l'autre sur le ruban inférieur.As still shown in FIG. 1, two
Dans la pratique, pour réaliser le câble de l'invention, on part d'un câble électrique chauffant revêtu d'un ruban continu diffuseur de chaleur, on découpe en des endroits prédéterminés des encoches de manière à réaliser les tronçons des coudes, puis on replie les segments dans un sens ou dans l'autre alternativement en respectant la forme des coudes, et enfin on pose en continu les rubans adhésifs formant les lanières.In practice, to produce the cable of the invention, one starts with an electric heating cable coated with a continuous heat-diffusing tape, notches are cut at predetermined locations so as to produce the sections of the elbows, then fold the segments in one direction or the other alternately, respecting the shape of the elbows, and finally the adhesive tapes forming the strips are applied continuously.
Selon la puissance thermique désirée par unité de surface, on prévoit des encoches plus ou moins rapprochées dans les coudes pour faire varier leurs diamètres, de façon à faire varier la distance mutuelle entre les segments rectilignes.Depending on the desired thermal power per unit area, more or less closely spaced notches are provided in the elbows to vary their diameters, so as to vary the mutual distance between the straight segments.
Bien entendu, si ayant étendu dans un sens un réseau tel que celui de la Fig. 1, on désire continuer à l'étendre mais dans l'autre sens, il suffit au point de changement de direction de redresser manuellement un coude pour aligner deux segments successifs. A noter que le réseau de la Fig. 1 peut être livré enroulé sur un touret dans le sens des rubans 6 et 7.Of course, if having extended in a direction a network such as that of FIG. 1, we want to continue to extend it but in the other direction, it is enough at the point of change of direction to manually straighten an elbow to align two successive segments. Note that the network in Fig. 1 can be supplied wound on a reel in the direction of
De petits trous, tels que 8, peuvent être poinçonnés dans les ailes du ruban, pour permettre de poser des punaises dont la tige s'accroche dans la couche isolante au-dessous du câble, après la pose de ce dernier.Small holes, such as 8, can be punched in the wings of the tape, to allow the installation of thumbtacks, the rod of which hangs in the insulating layer below the cable, after the cable has been laid.
