Description

Flexible HeizmatteFlexible heating mat

Die Erfindung betrifft eine flexible Heizmatte, welche in ihren verschiedenen Ausführungsformen entweder zur Unterlage unter einen Fußbodenbelag, wie zum Beispiel Teppich, Linoleum, Auslegware, in Wohnwagen, Booten, Fahrzeugen und anderen Räumlichkeiten dient bzw. in einer weiteren Ausführungsform zum Einkleben in Dünnbett oder Estrich, unter Fliesen, Terrazzo und Marmor oder anderen Fußbodenbelägen ausgeführt ist.The invention relates to a flexible heating mat, which in its various embodiments is used either as a base under a floor covering, such as carpet, linoleum, carpeting, in caravans, boats, vehicles and other rooms, or in a further embodiment for gluing in thin bed or screed , under tiles, terrazzo and marble or other floor coverings.

Bekannt sind diverse Heizmattensysteme und Verfahren zu ihrer Verlegung, wie zum Beispiel DE 41 12 565. Dabei handelt es sich um eine Heizmatte, welche aus einem flexiblen Träger besteht, bei dem ein Heizleiter integriert ist. Der Träger ist aus einer porösen Struktur und bildet eine Vielzahl von Durchtrittsöffnungen. Es wird nachfolgend eine Dämmschicht aus Hartschaum, die auf ihrer Oberseite mit einer Feuchtigkeitssperre versehen ist, aufgelegt und mit Estrich bedeckt. Wie aus der Beschreibung erkennbar ist, handelt es sich hierbei um eine Heizmatte, welche als eine klassische Fußbodenheizung in den Fußboden unflexibel eingearbeitet wird. Zu dieser Problematik sind weitere Lösungen bekannt, wobei jeweils immer der Nachteil anhaftet, daß eine unflexible Verlegung der Heizmatte gegeben ist und eine Einarbeitung in ein Fußbodensystem durchgeführt wird und somit eine Verlegung unter einen Fußbodenbelag ohne Einbindung in einen Estrich oder andere Bindemittel durchgeführt ist.Various heating mat systems and methods for their laying are known, such as DE 41 12 565. This is a heating mat which consists of a flexible carrier in which a heating conductor is integrated. The carrier is made of a porous structure and forms a variety of Openings. Subsequently, an insulation layer made of hard foam, which is provided with a moisture barrier on its top, is placed on top and covered with screed. As can be seen from the description, this is a heating mat which is inflexibly incorporated into the floor as a classic underfloor heating. Further solutions to this problem are known, each with the disadvantage that there is an inflexible laying of the heating mat and incorporation into a floor system is carried out and thus a laying under a floor covering without incorporation into a screed or other binding agent is carried out.

Ziel der Erfindung ist es, eine flexible Heizmatte zu schaffen, welche in ihrer Ausführungsform entweder als Unterlage unter einem Fußbodenbelag, wie zum Beispiel Teppich, Linoleum, Auslegware, in Wohnwagen, Booten, Fahrzeugen oder anderen Räumlichkeiten ausgeführt ist und weiterhin eine Verlegung zum Einkleben in Dünnbett oder Estrich unter Fliesen, Terrazzo, Marmor und anderen Fußbodenbelägen stattfindet, wobei die flexible Heizmatte je nach Anwendungsfall operativ verlegbar ausgeführt ist.The aim of the invention is to provide a flexible heating mat, which is designed in its embodiment either as a base under a floor covering, such as carpet, linoleum, carpeting, in caravans, boats, vehicles or other rooms and also a laying for gluing in Thin bed or screed takes place under tiles, terrazzo, marble and other floor coverings, whereby the flexible heating mat can be surgically installed depending on the application.

Der Erfindung liegt die Aufgabe zugrunde, eine flexible Heizmatte, insbesondere zur Unterlage unter einem Fußbodenbelag, wie zum Beispiel Teppich, Linoleum, Auslegware, in Wohnwagen, Booten, Fahrzeugen oder anderen Räumlichkeiten bzw. zum Einkleben in Dünnbett oder Estrich unter Fliesen, Terrazzo, Marmor und anderen Fußbodenbelägen zu realisieren, wobei eine flexible Heizmatte je nach Anwendungsfall in ihrer Größe variabel ausführbar ist und durch den spezielle Aufbau eine hohe Stabilität aufweist.The invention has for its object a flexible heating mat, in particular for underlaying a floor covering, such as carpet, linoleum, carpeting, in caravans, boats, vehicles or other rooms or for gluing in thin beds or screed under tiles, Realize terrazzo, marble and other floor coverings, whereby a flexible heating mat can be varied in size depending on the application and has a high stability due to the special structure.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß eine flexible Heizmatte gemäß des Patentanspruches 1 und seinen Unteransprüchen ausgeführt wird.According to the invention the object is achieved in that a flexible heating mat is executed according to claim 1 and its subclaims.

Dabei wird eine flexible Heizmatte zur Lösung der aufgabengemäßen Realisierung so ausgeführt, daß ein Heizleiter, welcher in gerader Form oder in mäanderförmiger Weise verlegt ist und dabei oberhalb und unterhalb der Heizleiter mit einem Glasfasergittergewebe umschlossen ist. Dieser Aufbau aus dem Glasfasergittergewebe und dem beinhalteten Heizleiter wird nun mit einem PUR-Kunststoff oder ähnliches vergossen, wobei eine Matte von ca. 1,5 bis 2,0 mm Stärke entsteht. Somit wird der gesamte Aufbau dauerhaft verbunden, die Anschlüsse elektrisch isoliert und die Wärme vom Heizleiter über die Fläche gleichmäßig verteilt. Durch diese flexible Heizmatte ist es möglich, dem Anwender ohne größere Probleme die entsprechenden Maße nach Bedarf zurechtzuschneiden. Die Einspeisung des Heizleiters erfolgt über entsprechende Sammelleiter, welche mit dem Heizleiter an den entsprechenden Punkten verbunden sind. Dabei wird vorzugsweise mit einer Schutzkleinspannung von 48 Volt gearbeitet. An den jeweiligen Enden der Sammelleiter wird die Speiseleitung angeschlossen. Der Vorteil der Erfindung liegt darin begründet, daß auf Grund der Stärke von 1,5 bis 2,0 mm die flexible Heizmatte ohne Probleme eine Verlegung unter einem vorhandenen Fußbodenbelag (Teppich, Linoleum, Auslegware) in Einsatzgebieten, wie Wohnwagen, Booten, Fahrzeugen oder anderen Räumlichkeiten gestattet. Wichtig ist dabei zu betrachten, daß durch die geringe Stärke der flexiblen Heizmatte keine weiteren Maßnahmen bei der Auslage des gegebenen Fußbodenbelages notwendig ist.A flexible heating mat to solve the task is carried out so that a heating conductor, which is laid in a straight form or in a meandering manner and is enclosed above and below the heating conductor with a glass fiber mesh. This structure made of the glass fiber mesh and the included heat conductor is now cast with a PUR plastic or the like, creating a mat of approx. 1.5 to 2.0 mm thick. The entire structure is thus permanently connected, the connections are electrically insulated and the heat from the heating conductor is evenly distributed over the surface. This flexible heating mat makes it possible for the user to cut the appropriate dimensions as required without major problems. The heating conductor is fed in via appropriate busbars, which are connected to the heating conductor at the corresponding points. A protective low voltage of 48 volts is preferably used. The feed line is connected to the respective ends of the busbars. The advantage of the invention is based on the fact that, due to the thickness of 1.5 to 2.0 mm, the flexible heating mat can easily be laid under an existing floor covering (carpet, linoleum, carpeting) in areas of application such as caravans, boats, vehicles or other premises allowed. It is important to consider that the low thickness of the flexible heating mat means that no further measures are required when laying out the given floor covering.

Des weiteren wird eine flexible Heizmatte aufgabengemäß in der erfinderischen Ausführungsform so ausgeführt, daß ein Heizleiter, welcher in gerader Form oder mäanderförmiger Weise verlegt ist und dabei oberhalb und unterhalb der Heizleiter mit einem Glasfasergittergewebe umschlossen ist. Dieser Aufbau des Glasfasergittergewebes und dem beinhalteten Heizleiter, welcher an bestimmten Lötpunkten mit einem Sammelleiter verbunden ist, wird nun mit einem Kunststoff, insbesondere PUR-Kunststoff oder ähnlichen Kunststoffen, vergossen, wobei jeweils nur der Sammelleiter mit den Lötpunkten des Heizleiters und den Wendepunkten des Heizleiters mit dem entsprechenden Kunststoff vergossen ist. Der weitere Bestandteil der Heizmatte im inneren Bereich bleibt mit dem oberen Glasfasergittergewebe und dem unteren Glasfasergittergewebe mit dem beinhalteten Heizleiter ohne einen Kunststoffverguß . Die Stärke der Matte weist dabei eine Höhe von ca. 1,5 bis 2,0 mm Stärke an den Außenrändern auf. Durch diese Außenummantelung mit PUR-Kunststoff wird der Aufbau dauerhaft verbunden und die Anschlüsse elektrisch isoliert, wobei die Wärme vom Heizleiter über die Flächen der nachfolgenden Einklebung bzw. des aufgetragenen Estrichs oder andere Verbundmittel übertragen wird.Furthermore, a flexible heating mat is carried out according to the task in the inventive embodiment in such a way that a heating conductor which is laid in a straight form or in a meandering manner and is enclosed above and below the heating conductor with a glass fiber mesh fabric. This structure of the glass fiber mesh and the included heating conductor, which is connected to a busbar at certain soldering points, is now cast with a plastic, in particular PUR plastic or similar plastics, only the busbar with the soldering points of the heating cable and the turning points of the heating cable is potted with the appropriate plastic. The other part of the heating mat in the inner area remains with the upper fiberglass mesh and the lower fiberglass mesh with the included heat conductor without a plastic potting. The thickness of the mat is about 1.5 to 2.0 mm thick on the outer edges. Through this outer sheathing The structure is permanently connected with PUR plastic and the connections are electrically insulated, whereby the heat is transferred from the heating conductor to the surfaces of the subsequent gluing or the applied screed or other composite materials.

Damit ist es möglich, die flexible Heizmatte zum Einkleben in Dünnbett oder Estrich unter Fliesen, Terrazzo, Marmor oder anderen Fußbodenbelägen einzuarbeiten. Dabei wird der mittlere Bereich, welcher nicht mit Kunststoff ausgefüllt ist, zur Durchdringung des Klebers bzw. Estrichs oder ähnliches genutzt. Des weiteren sind Markierungen zur Quertrennung der Matte vorhanden, wobei der Anwender die Möglichkeit besitzt, die entsprechende flexible Heizmatte für seinen Anwendungsbereich in verschiedene Längen zu schneiden. Die Einspeisung des Heizleiters erfolgt über entsprechende Sammelleiter, welche mit dem Heizleiter an den entsprechenden Punkten verbunden sind. Dabei wird vorzugsweise mit einer Schutzkleinspannung von 48 Volt gearbeitet. An den jeweiligen Enden der Sammelleiter wird die Speiseleitung angeschlossen. Die flexible Heizmatte kann von einer Rolle für die entsprechenden Längenmaße je nach Anwendungsfall zugeschnitten und in eine Unterbettung für entsprechende Anwendungsfälle, wie zum Beispiel Dünnbett, Estrich, Fliesen, Terrazzo, Marmor oder andere Fußbodenbeläge verlegt werden. Durch die beiderseitige Umschließung des Heizleiters mit seinen Lötpunkten und dem Sammelleiter mit dem PUR-Kunststoff sowie die Umschließung des Heizleiters mit dem Glasfasergittergewebe oberhalb und unterhalb ist die unvergossene Heizmatte vor und nach dem Verguß mechanisch stabiler als herkömmliche Heizmattensysteme. Ein weiterer Vorteil der Erfindung ist darin begründet, daß auf Grund der Stärke von 1,5 bis 2,0 mm der flexiblen Heizmatte ohne Probleme eine Verlegung oder ein Einkleben in ein Dünnbett oder Estrich unter Fliesen, Terrazzo, Marmor oder anderen Fußbodenbelägen stattfinden kann und somit eine kostensparende Wand- bzw. Fußbodenheizung möglich ist .This makes it possible to incorporate the flexible heating mat for gluing in a thin bed or screed under tiles, terrazzo, marble or other floor coverings. The middle area, which is not filled with plastic, is used to penetrate the adhesive or screed or the like. Furthermore, there are markings for cross-cutting the mat, whereby the user has the option of cutting the corresponding flexible heating mat into different lengths for his area of application. The heating conductor is fed in via appropriate busbars, which are connected to the heating conductor at the corresponding points. A protective low voltage of 48 volts is preferably used. The feed line is connected to the respective ends of the busbars. The flexible heating mat can be cut from a roll for the appropriate length dimensions depending on the application and laid in an underbedding for corresponding applications, such as thin bed, screed, tiles, terrazzo, marble or other floor coverings. By enclosing the heating conductor on both sides with its soldering points and the busbar with the PUR plastic and enclosing the heating conductor with the Glass fiber mesh fabric above and below the non-encapsulated heating mat before and after casting is mechanically more stable than conventional heating mat systems. Another advantage of the invention is that, due to the thickness of 1.5 to 2.0 mm of the flexible heating mat, laying or gluing into a thin bed or screed under tiles, terrazzo, marble or other floor coverings can take place without problems and thus a cost-saving wall or floor heating is possible.

Figur 1 zeigt den Aufbau einer flexiblen Heizmatte, wobei ersichtlich ist, daß hierbei der Heizleiter (3) mäanderförmig verlegt ist. Um diesen Heizleiter (3) wird oberhalb und unterhalb ein Glasfasergittergewebe (1 und 2) angeordnet, welches als Traggewebe dient und die mechanische Schutzfunktion erfüllt. Dieser komplette Aufbau aus Heizleiter (3) und Glasfasergittergewebe (1 und 2) wird nun mit einem speziellen PUR-Kunststoff (4) ausgegossen, womit eine flexible Heizmatte von ca. 1,5 bis 2,0 mm Stärke entsteht. Es handelt sich bei dieser flexiblen Heizmatte um eine elektrische flexible Fußbodenheizmatte, welche direkt unter den Fußbodenbelag, wie zum Beispiel Teppich, Linoleum und Auslegware, gelegt werden kann. Der Betrieb der Heizmatte erfolgt mit einer Schutzkleinspannung von 48 Volt. Der Vorteil der flexiblen Heizmatte liegt in seiner einfachen Anwendung. Diese flexible Heizmatte bedarf keiner Einbettung, wie zum Beispiel Estrich oder Kleber. Die Mattenlänge kann nach Bedarf auf die benotigten Maße vom Kunden oder vom Verleger ohne Sonderwerkzeuge geschnitten werden. Dadurch ergibt sich die Möglichkeit der problemlosen Umrüstung von Räumlichkeiten auf Fußbodenheizung oder als Ergänzung in Problemzonen. Des weiteren ergeben sich völlig neue Anwendungsgebiete, welche für Fußbodenheizung im herkömmlichen Sinne nicht realisierbar waren, insbesondere der Einsatz in Wohnwagen, Booten, Fahrzeugen oder anderen räumlichen Gestaltungsformen. Die Vorder- und Rückseite der flexiblen Heizmatte besteht aus Glasfasergittergewebe, welches als Traggewebe dient und die mechanische Schutzfunktion erfüllt. In der Ober- und Unterseite der flexiblen Heizmatte findet sich der obere und der untere Sammelleiter (5) . Die beiden Sammelleiter (5) ziehen sich über die gesamte Länge der Heizmatte hin. Der Sammelleiter (5) besteht aus Flachkupferlitze oder einem anderen elektrischen leitfähigen Material. Die Aufgabe der beiden Sammelleiter (5) ist es, die dazwischen liegenden Heizleiter (3) mit der entsprechenden Energie zu versorgen. Der Heizleiter (3) besteht aus teflonisolierter Heizlitze. Das eine Ende des Heizleiters (3) ist am oberen Sammelleiter (5) und das andere Ende des Heizleiters (3) ist mit dem unteren Sammelleiter (5) elektrisch verbunden, vorzugsweise gelötet bzw. geschweißt. Der Heizleiter (3) kann gerade durchgeführt oder einige Lagen mäanderförmig verlegt sein. Der Heizleiterabstand beträgt ca. 1 cm. Dieser komplette Aufbau wird mit einem speziellen PUR-Kunststoff oder ähnliches von einer ca. 1,5 bis 2,0 mm starken Matte vergossen. Somit wird der gesamte Aufbau dauerhaft verbunden, die Anschlüsse elektrisch isoliert und die Wärme vom Heizleiter (3) über die Fläche gleichmäßig verteilt. Die Einspeisung der Matte erfolgt über die beiden Sammelleiter (5) . An den Enden der beiden Sammelleiter (5) wird eine Speiseleitung angeschlossen. Ein anderes Ende der flexiblen Heizmatte wird durch ein Kunststoffprofil abgeschlossen.Figure 1 shows the structure of a flexible heating mat, it being apparent that the heating conductor (3) is laid in a meandering manner. A glass fiber mesh fabric (1 and 2), which serves as a supporting fabric and fulfills the mechanical protective function, is arranged above and below this heating conductor (3). This complete structure consisting of the heating conductor (3) and glass fiber mesh (1 and 2) is now cast with a special PUR plastic (4), creating a flexible heating mat of approx. 1.5 to 2.0 mm thick. This flexible heating mat is an electrically flexible one Floor heating mat, which can be placed directly under the floor covering, such as carpet, linoleum and carpeting. The heating mat is operated with a protective low voltage of 48 volts. The advantage of the flexible heating mat is that it is easy to use. This flexible heating mat does not require embedding, such as screed or glue. As required, the mat length can be cut to the required dimensions by the customer or by the installer without special tools. This results in the possibility of easily converting rooms to underfloor heating or as a supplement in problem areas. Furthermore, there are completely new areas of application which were not feasible for underfloor heating in the conventional sense, in particular the use in caravans, boats, vehicles or other spatial designs. The front and back of the flexible heating mat consists of glass fiber mesh, which serves as a supporting fabric and fulfills the mechanical protective function. The top and bottom busbars (5) are located in the top and bottom of the flexible heating mat. The two busbars (5) extend over the entire length of the heating mat. The busbar (5) consists of flat copper wire or another electrically conductive material. The task of the two busbars (5) is to supply the heating conductors (3) between them with the appropriate energy. The heating conductor (3) consists of Teflon-insulated heating wire. One end of the heating conductor (3) is on the upper busbar (5) and the other end of the heating conductor (3) is with the lower busbar (5) electrically connected, preferably soldered or welded. The heating conductor (3) can be straight or some layers can be laid in a meandering shape. The heating conductor distance is approx. 1 cm. This complete structure is cast with a special PUR plastic or similar from an approx. 1.5 to 2.0 mm thick mat. The entire structure is thus permanently connected, the connections are electrically insulated and the heat from the heating conductor (3) is evenly distributed over the surface. The mat is fed in via the two busbars (5). A feed line is connected to the ends of the two busbars (5). Another end of the flexible heating mat is closed by a plastic profile.

Ein weiteres Beispiel wird in der Figur 2 beschrieben. Dabei zeigt die Figur 2 den Aufbau einer flexiblen Heizmatte, wobei ersichtlich ist, daß hierbei der Heizleiter (3) mäanderförmig verlegt ist. Um diesen Heizleiter (3) wird oberhalb und unterhalb ein Glasfasergittergewebe (1 und 2) angeordnet, welches als Tragegewebe dient und die mechanische Schutzfunktion erfüllt. Dieser komplette Aufbau des Heizleiters (3) und Glasfasergittergewebes (1 und 2) wird nun mit einem speziellen PUR-Kunststoff (4) dahingehend ausgegossen, daß hierbei nur die Ränder mit dem Sammelleiter (5), den Wendenschleifen des Heizleiters (3) und die Lötpunkte des Heizleiters (3) mit dem Sammelleiter (5) vergossen sind. Dabei wird eine Vergußstärke von ca. 1,5 bis 2,0 mm an den Außenrandern ausgeführt. In der Ober- und Unterseite der flexiblen Heizmatte befinden sich der obere und untere Sammelleiter (5) . Die beiden Sammelleiter (5) ziehen sich über die gesamte Länge der Heizmatte hin. Der Sammelleiter (5) besteht aus Flachkupferlitze oder anderen elektrischen leitfähigen Materialien. Die Aufgabe der beiden Sammelleiter ist es, die dazwischen liegenden Heizleiter (3) mit der entsprechenden Energie zu versorgen. Der Heizleiter (3) besteht aus teflonisolierten Heizlitzen. Das eineAnother example is described in FIG. 2. 2 shows the structure of a flexible heating mat, it being evident that the heating conductor (3) is laid in a meandering manner. A glass fiber mesh fabric (1 and 2), which serves as a supporting fabric and fulfills the mechanical protective function, is arranged above and below this heating conductor (3). This complete structure of the heating conductor (3) and fiberglass mesh (1 and 2) is now poured out with a special PUR plastic (4) such that only the edges with the busbar (5), the spiral loops of the heating conductor (3) and the Soldering points of the heating conductor (3) are cast with the busbar (5). A casting thickness of approx. 1.5 to 2.0 mm is applied to the Outside edges executed. The upper and lower busbars (5) are located in the top and bottom of the flexible heating mat. The two busbars (5) extend over the entire length of the heating mat. The busbar (5) consists of flat copper wire or other electrically conductive materials. The task of the two busbars is to supply the heating conductors (3) between them with the appropriate energy. The heating conductor (3) consists of Teflon-insulated heating strands. The one

Ende des Heizleiters (3) ist am oberen SammelleiterThe end of the heating conductor (3) is on the upper busbar

(5) und das andere Ende des Heizleiters (3) ist mit dem unteren Sammelleiter (5) elektrisch verbunden, vorzugsweise gelötet bzw. geschweißt. Diese Lötpunkte bzw. Schweißpunkte sind jeweils in der Einbettung des Randvergusses mit dem PUR-Kunststoff eingebettet. Der Heizleiter (3) kann gerade durchgeführt oder einige Lagen mäanderförmig verlegt sein. Der Heizleiterabstand beträgt ca. 1 cm. Die Möglichkeit des Benutzers besteht nun auf Grund seines Anwendungsfalles anhand der Lötpunkte einen Zuschnitt der flexiblen Heizmatte durchzuführen und somit eine anwendungsbedingte Länge zu bestimmen. An dem Sammelleiter (5) , welcher mit dem Heizleiter an den entsprechenden Punkten verbunden ist, wird vorzugsweise eine Schutzkleinspannung von 48 Volt angeschlossen. An den jeweiligen Enden der Sammelleiter (5) wird die Schutzspeiseleitung angeschlossen. Diese flexible Ausführung der Einspeisung der flexiblen Heizmatte bedarf keiner besonderen Kenntnisse. Durch diese spezielle Ausführung ist es nun möglich, die in Figur 2 beschriebene flexible Heizmatte insbesondere zum Einkleben in Dünnbett oder Estrich unter Fliesen, Terrazzo, Marmor oder anderen Fußbodenbelägen zu benutzen. Dabei wird durch den Außenrandverguß mit PUR-Kunststoff eine Stabilität der flexiblen Heizmatte gewährt. Die Heizmatte kann nun von einer Rolle auf das entsprechende Längenmaß geschnitten werden. Dadurch kann durch den Anwender oder Lieferanten bedeutend schneller und kostengünstig auf bauliche Anforderungen reagiert werden. Durch die beiderseitige Umschließung des Heizleiters (3) mit dem Glasfasergittergewebe (1 und 2) ist die unvergossene Heizmatte vor und nach dem Verguß mechanisch stabiler als herkömmliche Systeme. Durch die am Außenrand vergossene flexible Heizmatte mit PUR-Kunststoff wird der gesamte Aufbau dauerhaft verbunden, die Anschlüsse elektrisch isoliert und die Wärme von dem Heizleiter (3) über die vergossene Fläche gleichmäßig verteilt. Die Einspeisung der Matte erfolgt über die beiden Sammelleiter (5) . Das andere Ende der flexiblen Heizmatte wird durch ein Kunststoffprofil nach Zuschnitt der entsprechenden Länge elektrisch abgeschlossen.(5) and the other end of the heating conductor (3) is electrically connected to the lower busbar (5), preferably soldered or welded. These soldering points or welding points are embedded in the embedding of the edge encapsulation with the PUR plastic. The heating conductor (3) can be straight or some layers can be laid in a meandering shape. The heating conductor distance is approx. 1 cm. The user now has the option of cutting the flexible heating mat based on the soldering points and thus determining an application-related length. A protective low voltage of 48 volts is preferably connected to the busbar (5), which is connected to the heating conductor at the corresponding points. The protective feed line is connected to the respective ends of the busbars (5). This flexible design of the feeding of the flexible heating mat does not require any special knowledge. Due to this special design, it is now possible to achieve the Use the described flexible heating mat especially for gluing in a thin bed or screed under tiles, terrazzo, marble or other floor coverings. The outer edge potting with PUR plastic ensures the stability of the flexible heating mat. The heating mat can now be cut from a roll to the appropriate length. This means that the user or supplier can respond to construction requirements significantly faster and at lower cost. Because the heating conductor (3) is enclosed on both sides with the glass fiber mesh (1 and 2), the non-encapsulated heating mat is mechanically more stable before and after casting than conventional systems. The flexible heating mat encapsulated on the outside with PUR plastic permanently connects the entire structure, the connections are electrically insulated and the heat from the heating conductor (3) is evenly distributed over the encapsulated surface. The mat is fed in via the two busbars (5). The other end of the flexible heating mat is electrically closed by a plastic profile after cutting the appropriate length.

Wie in den beiden Ausführungsbeispielen beschrieben, ergeben sich wesentliche Vorteile des erfindungsgemäßen Aufbaus der flexiblen Heizmatte. Je nach spezieller Ausführungsform ist es möglich, einen entsprechenden Anwendungsfall mit oder ohne Einfügen in eine bestimmte Bedeckungsschicht auszuführen. Wesentlich ist dabei die geringe Dicke der flexiblen Heizmatte von 1,5 bis 2,0 mm. Die Flexibilität und Stabilität ist auf Grund der Umschließung des Heizleiters (3) mit dem Glasfasergittergewebe (1 und 2) oberhalb und unterhalb und die elektrische Isolierung durch den Vollguß mit dem PUR-Kunststoff bzw. dem Randverguß mit dem PUR-Kunststoff gewährt. As described in the two exemplary embodiments, there are significant advantages of the construction of the flexible heating mat according to the invention. Depending on the specific embodiment, it is possible to carry out a corresponding application with or without insertion into a specific covering layer. The small thickness of the flexible heating mat of 1.5 to 2.0 mm is essential. The flexibility and Stability is guaranteed due to the encasing of the heating conductor (3) with the glass fiber mesh (1 and 2) above and below and the electrical insulation through the full casting with the PUR plastic or the edge casting with the PUR plastic.
