Heating elements are attached using loops (16). When heating structure is laid down, structure is stretched along arrow (E), i.e. in direction perpendicular to heating elements. Stretching factor of heating structure can reach 200%, or even 400%. An Independent claim is also included for the manufacturing method of the under floor heater.

Description

La présente invention concerne une structure chauffante électrique, notamment pour le chauffage par le sol. The present invention relates to an electric heating structure, in particular for underfloor heating.

Il est connu de fabriquer des planchers chauffants en disposant sur le sol avant coulage d'une chape ou d'une dalle un grillage en matière plastique et en fixant sur ce dernier une structure électrique comprenant des éléments chauffants destinés à être parcourus par un courant électrique. It is known to manufacture heated floors by placing on the ground before pouring a screed or a slab of plastic mesh and by fixing on the latter an electrical structure comprising heating elements intended to be traversed by an electric current. .

La pose de la structure électrique sur le grillage en matière plastique une operation assez longue et coûteuse en main d'oeuvre, car les éléments chauffants doivent être répartis sur le sol en fonction de la puissance de chauffe requise par unité de surface, laquelle n'est pas la même selon les pièces d'une habitation, étant d'une manière genérale plus faible dans une salle de bains que dans un couloir par exemple. The installation of the electrical structure on the plastic mesh is a fairly long and labor-intensive operation, since the heating elements must be distributed over the floor according to the heating power required per unit area, which does not is not the same according to the rooms of a house, being generally weaker in a bathroom than in a corridor for example.

La présente invention vise à proposer une structure chauffante électrique permettant de simplifier l'opération de pose. The present invention aims to provide an electric heating structure to simplify the laying operation.

Un autre objet de la présente invention est de proposer une structure chauffante électrique permettant de réaliser plus aisément un plancher chauffant ayant puissance surfacique déterminée. Another object of the present invention is to provide an electric heating structure making it easier to produce a heating floor having a determined surface power.

La structure chauffante selon l'invention est du type comportant une structure électrique comprenant des éléments chauffants destinés à être parcourus par un courant électrique, fixés à un support, et se caractérise par le fait que le support est déformable dans au moins une direction et la structure électrique déformable dans cette direction de manière à accompagner les déformations du support, la structure électrique étant agencée le support de telle sorte que sa déformation entraine une modification de l'écartement entre les éléments chauffants, d'où une puissance surfacique modulable. The heating structure according to the invention is of the type comprising an electrical structure comprising heating elements intended to be traversed by an electric current, fixed to a support, and is characterized in that the support is deformable in at least one direction and the deformable electrical structure in this direction so as to accompany the deformations of the support, the electrical structure being arranged the support so that its deformation causes a modification of the spacing between the heating elements, hence a modular surface power.

Ainsi, la pose de la structure chauffante s'effectue aisément car suffit d'étirer le support à la longueur voulue pour que les éléments chauffants s'écartent d'une manière sensiblement homogène, plus ou moins en fonction du facteur d'allongement du support. Thus, the installation of the heating structure is carried out easily because it suffices to stretch the support to the desired length so that the heating elements deviate in a substantially homogeneous manner, more or less depending on the elongation factor of the support .

La structure chauffante selon l'invention peut être posée par exemple à l'état étiré sur le sol d'une salle de bains, tandis qu'elle est posée en étant étirée au maximum sur le sol d'un couloir, générant ainsi une puissance surfacique adaptée. The heating structure according to the invention can be placed, for example, in the stretched state on the floor of a bathroom, while it is laid by being stretched as much as possible on the floor of a corridor, thus generating a power adapted surface.

Dans une réalisation particulière, le support comporte une structure réticulaire en matière plastique à mailles de forme losange. Une telle structure peut être réalisée aisément par extrusion, de façon connue en soi. In a particular embodiment, the support comprises a reticular structure in plastic material with diamond-shaped meshes. Such a structure can be easily produced by extrusion, in a manner known per se.

Dans une autre réalisation particulière, le support comporte une feuille pourvue de fentes disposées en quinconce. In another particular embodiment, the support comprises a sheet provided with slots staggered.

Cette feuille peut être étirée dans une direction perpendiculaire aux fentes. Les éléments chauffants sont avantageusement orientés transversalement à la direction dans laquelle le support s'allonge. This sheet can be stretched in a direction perpendicular to the slits. The heating elements are advantageously oriented transversely to the direction in which the support elongates.

L'invention a également pour objet un support destiné à la réalisation d'une structure chauffante telle que définie plus haut. The invention also relates to a support intended for the production of a heating structure as defined above.

L'invention a encore pour objet un procédé de réalisation d'un plancher chauffant, caractérisé par le fait qu'il comporte les étapes consistant à - poser sur le sol une structure chauffante comportant une structure électrique destinée à être parcourue par un courant électrique et un support déformable sur lequel ladite structure 'lectrique est fixée, cette dernière étant déformable de manière à accompagner les déformations du support, - étirer le support, - maintenir support à l'état étiré et le fixer, et - couler chape ou une dalle dessus. The invention also relates to a method of producing a heated floor, characterized in that it comprises the steps consisting in - placing on the ground a heating structure comprising an electrical structure intended to be traversed by an electric current and a deformable support on which said electrical structure is fixed, the latter being deformable so as to accompany the deformations of the support, - stretch the support, - maintain support in the stretched state and fix it, and - pour screed or a slab on it .

Avantageusement, on détermine le facteur d'allongement à donner au support en répartissant la structure chauffante de façon homogène sur la surface de la pièce. D'autres caractéristiques et avantages de la présente invention ressortiront à la lecture de la description détaillée qui va suivre, d'exemples de réalisation non limitatifs de l'invention, et à l'examen du dessin annexé sur lequel - la figure est une vue schématique de dessus d'une structure chauffante électrique conforme à premier exemple de mise en oeuvre de l'invention, et - la figure 2 une vue schématique de dessus d'une structure chauffante électrique conforme à un deuxième exemple de mise en oeuvre de l'invention. Advantageously, the elongation factor to be given to the support is determined by distributing the heating structure evenly over the surface of the part. Other characteristics and advantages of the present invention will emerge on reading the detailed description which follows, of nonlimiting exemplary embodiments of the invention, and on examining the appended drawing in which - the figure is a view schematic from above of an electric heating structure according to first example of implementation of the invention, and - Figure 2 a schematic view from above of an electric heating structure according to a second example of implementation of the invention.

La structure chauffante 10 représentée sur la figure 1 comporte un support 11 constitué par un materiau réticulaire en matière plastique, à mailles de forme losange. The heating structure 10 shown in FIG. 1 comprises a support 11 constituted by a reticular material of plastic material, with diamond-shaped meshes.

Les mailles sont allongées dans la direction d'extrusion. The meshes are elongated in the direction of extrusion.

La structure chauffante 10 comporte également une structure électrique 12 comprenant une pluralité d'éléments chauffants rectilignes 13 sensiblement parallèles, reliés à leurs extrémités par des boucles 16. The heating structure 10 also includes an electrical structure 12 comprising a plurality of substantially parallel rectilinear heating elements 13, connected at their ends by loops 16.

Chaque élément chauffant 13 est fixé au support 11 plusieurs points de sa longueur, au niveau des entrecroisements des brins de matière plastique constituant le support 11, au moyen d'attaches telles que des agrafes 14 par exemple. Each heating element 13 is fixed to the support 11 at several points along its length, at the intersections of the strands of plastic material constituting the support 11, by means of fasteners such as staples 14 for example.

La structure chauffante 10 est représentée sur figure 1 dans une configuration non étirée. The heating structure 10 is shown in Figure 1 in an unstretched configuration.

Elle est livrée aux utilisateurs en bandes de 2 m de longueur par exemple. It is delivered to users in strips of 2 m in length for example.

Au moment de l'utilisation, la structure chauffante 10 est posée sur le sol, puis maintenue par bord et étirée par l'autre bord dans le sens de la flèche E sur la figure 1, c'est-à-dire dans une direction perpendiculaire à la direction d'extrusion et aux éléments chauffants 13. At the time of use, the heating structure 10 is placed on the ground, then held by edge and stretched by the other edge in the direction of arrow E in FIG. 1, that is to say in one direction perpendicular to the direction of extrusion and the heating elements 13.

Si surface à couvrir est plus étendue que la surface couverte par la structure chauffante 10 à l'état d'étirement maximal, plusieurs bandes sont utilisées en étant juxtaposées. If the surface to be covered is larger than the surface covered by the heating structure 10 in the state of maximum stretching, several strips are used in being juxtaposed.

Le facteur d'allongement de la structure chauffante peut atteindre 200 % voire 400 %. The elongation factor of the heating structure can reach 200% or even 400%.

Lors de l'étirement de la structure chauffante 10, les boucles 16 reliant les éléments chauffants 13 se déploient pour accompagner l'extension du support 11, les éléments chauffants 13 restant sensiblement parallèles. When stretching the heating structure 10, the loops 16 connecting the heating elements 13 deploy to accompany the extension of the support 11, the heating elements 13 remaining substantially parallel.

On obtient, après étirement de la structure chauffante 10, des éléments chauffants 13 ayant un écartement plus important. After stretching the heating structure 10, heating elements 13 having a greater spacing are obtained.

Une chape ou une dalle est ensuite coulée pour recouvrir la structure chauffante. A screed or slab is then poured to cover the heating structure.

Le support 11 maintient les éléments chauffants 13 sensiblement dans un plan, de manière à permettre à la chape ou la dalle de recouvrir toute la structure chauffante 10. The support 11 keeps the heating elements 13 substantially in a plane, so as to allow the screed or the slab to cover the entire heating structure 10.

On comprend que l'on obtient grâce à l'invention un écartement sensiblement régulier entre les éléments chauffants 13, quel que soit le degré d'étirement du support 11. It will be understood that, thanks to the invention, a substantially regular spacing is obtained between the heating elements 13, whatever the degree of stretching of the support 11.

La structure électrique 12 est ainsi répartie de façon sensiblement homogène sur la surface couverte par le support 11, ce qui permet de disposer d'une puissance surfacique constante. The electrical structure 12 is thus distributed in a substantially homogeneous manner over the surface covered by the support 11, which makes it possible to have a constant surface power.

On a représenté sur la figure 2 une structure électrique chauffante 20 qui diffère de celle précédemment décrite par le fait que le support 21 est constitué ici par une feuille de matière plastique pourvue de fentes 25 parallèles disposées en quinconce. FIG. 2 shows an electric heating structure 20 which differs from that previously described in that the support 21 is constituted here by a sheet of plastic material provided with parallel slots 25 arranged in staggered rows.

Une structure électrique en spires à plat 12 est fixée sur la feuille 21 par tout moyen approprié, les spires ayant des portions rectilignes constituant des éléments chauffants 13 parallèles aux fentes 25. An electrical structure in flat turns 12 is fixed to the sheet 21 by any suitable means, the turns having rectilinear portions constituting heating elements 13 parallel to the slots 25.

La feuille 21 peut être étirée dans une direction perpendiculaire aux fentes 25. Bien entendu, l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits. The sheet 21 can be stretched in a direction perpendicular to the slots 25. Of course, the invention is not limited to the exemplary embodiments which have just been described.

On peut notamment utiliser d'autres supports extensibles.One can in particular use other extensible supports.
