Abstract

The electrical heating cable is formed from a good heat-conducting strip having a longitudinal median groove in which the electrical cable (3) is housed and maintained. It is bent into a winding line each cycle of which comprises an elbow (2a) in a first direction, followed by a first rectilinear segment (1a), followed by an elbow (2b) in the second direction, followed by a second rectilinear segment (1b), parallel and equal to the first rectilinear segment, the cycles being allied and the electrical cable proper being uninterrupted. The elbows (2a, 2b) are produced by making suitable notches in the flat wings (5a, 5b) of the strip. The rectilinear segments (1a, 1b) are kept regularly spaced by a plurality of rectilinear latchets (6, 7) oriented perpendicularly to the segments. <IMAGE>

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 diffusers 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 coducteur 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 heat coder, 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. Furthermore, 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 in the vicinity of 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 they are laid. It therefore takes considerable time to equip a surface. For example, to equip a 40 m² room, it takes between two and three hours.

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.

Suivant une caractéristique de l'invention, le câble est conformé en une 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, parallèle et égal au premier segment recti­ligne, les cycles étant connexes et le câble électrique étant ininterrompu.According to a characteristic of the invention, the cable is shaped into a sinuous line, each cycle of which comprises a bend in a first direction, followed by a first straight segment, followed by a bend in the second direction, followed by a second rectilinear segment, parallel and equal to the first rectilinear segment, the cycles being connected and the electric cable being uninterrupted.

Suivant une autre caractéristique, les coudes sont pré­fabriqués en pratiquant des encoches adéquates dans les ailes planes du ruban.According to another characteristic, the elbows are prefabricated by making suitable notches in the flat wings of the ribbon.

Suivant une autre caractéristique, les segments rectilignes sont maintenus régulièrement espacés par une pluralité de lanières rectilignes orientées perpendiculairement aux segments.According to another characteristic, the rectilinear segments are kept regularly spaced apart by a plurality of rectilinear strips oriented perpendicular to the segments.

Suivant une autre caractéristique, une fois conformé, le câble est enroulé sur un touret dans sens des lanières pour être prêt à l'emploi.According to another characteristic, once shaped, the cable is wound on a reel in the direction of the straps to be ready for use.

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.
The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
  • 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 1a 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 la, 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 rectilinear segment la, followed by a bend 2a in the shape of a semicircle, followed by a segment 1b, it - 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.

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 electric cable 3, and two lateral wings which lie on a plane before wrapping the cable.

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 rectilinear segments 1a and 1b, the diffuser 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 °.

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 elbows 2a and 2b, as best shown in Fig. 2, 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 trapezoid 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.

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 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.

Comme le montrent encore les Figs. 1 et 2, 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 Figs. 1 and 2, two strips 6, perpendicular to the straight segments 1a and 1b, are hooked to said segments. The strips 6 and 7 extend over the entire winding line of the cable. The attachment points of the straps to the segments are spaced by a distance equal to the diameter of a bend 2a or 2b, so as to keep the straight segments parallel. In practice, the strips 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 straight segments being respectively glued one under the upper ribbon and the other on the lower ribbon.

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 make 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 ribbons 6 and 7.

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.
