Electrically operable wall heating plate for use in a wall structure of a building space

The invention relates to an electrically operable wall heating plate for use in a wall structure of a building space according to the preamble of claim 1.

Wall heating panels for use in a sidewall construction of a building room in the manner of electrically operable panel heating elements are well known. In addition to the demands for a simple and inexpensive production, good handling and an effective heating operation, there is in connection with the installation, in particular the requirement for a simple and reliable connection and connection of connecting cables to a control and power supply unit. In the case of the generally known wall heating plates, however, their contacting and connection for connecting cables to locally remote power supply units is usually inconvenient and can only be carried out with little reliability.

Object of the present invention is therefore to propose an electrically operable Wandheizplatte for use in a wall structure of a building space, in particular in the developments of the dependent claims a simple, convenient and secure electrical and mechanical connection with connecting cables is feasible, especially in Connection with a simple, cost-effective production and installation of the wall heating plate.

According to the invention, an electrically operable wall heating plate is proposed, which has a first rectangular building board as a base surface part, which z. B. when laying in conjunction with a side wall structure to the building wall out and with a lower narrow side edge to the building floor. The Wandheizplatte also has a second rectangular building board as a front surface part, which lies in the laying to the room interior and which has approximately the same width as the first building board, but z. B. is shorter in length by an edge offset at a non-square plate. As a third element, the wall heating plate has an electrically activatable thin heating layer, in particular a heating foil, in which an electrically activatable radiation heating coating is applied to a carrier foil in at least one heating field, with flat conductor strips, preferably copper strips with electrical contact, on both sides on the at least one heating field are attached to the radiant heater coating.

The wall heating plate is designed as a sandwich surface part in that the first building board and the second building board are connected to the heating layer or heating foil as an intermediate layer. In this case, the heating layer or heating foil can be embedded between the two building boards in such a way that it runs flush with the lower narrow side of the first building board, the two line strips on the heating film with line strip ends and connecting elements there being led into this area. The second building board, however, in any case, taking advantage of the edge offset so towards the first building board edge, z. B. in length, offset that in the region of one of the front or narrow sides of the wall heating a return edge with an accessibility of the heating layer or their contacting, in particular of line strip ends and local connection elements is formed. Reason- In addition, such a return edge could also be formed on two opposite end or narrow sides. However, the formation of the return edge on a single end face or narrow side is preferred, in particular in terms of easier installation. The term narrow side is basically understood to mean a shorter side than a longitudinal side of the plate; in the case of a quadrangular or square design of the respective plate, however, the narrow side is then only one of four end faces. Below is often spoken of a narrow side to illustrate the preferred case of a rectangular, but not square plate design example closer. Furthermore, the term wall construction here is understood to mean both a bottom wall and a side wall as well as a ceiling wall.

Nevertheless, here the wall heating is designed as a sandwich plate with an embedded heating foil, a contact and electrical and mechanical connection of connection cables can be easily and reliably installed in the accessible area of the return edge. The return area can be covered easily and optionally again detachably by a correspondingly high floor strip after complete installation of the wall heating. Suitably, the skirting board has a recess to the side wall, in which the connection cables can run concealed and protected. The wall heating plate according to the invention can also be easily and inexpensively manufactured.

In a particularly preferred embodiment, the building boards are plasterboard or gypsum fiber boards. In such embodiments, there are wall heating plates that have good stability and can be easily combined with non-heating gypsum board or gypsum fiberboard to complete a side wall. With the features of claim 5 preferred dimensions of a Wandheizplatte are claimed, which are convenient for convenient installation, good stability and combination with other panels.

Preferably, the return edge to the z. B. lower sides of a used or designed for the side wall construction heating plate over the entire width at a height at which the line strip ends with the local connection elements on the one hand are conveniently accessible and on the other hand, the cover of the Rücksprungrands by a commercially available cover strip, in here Example case by a baseboard is possible.

More preferably, the connection elements at the strip strip ends sub-elements fertilize conventional plug-in connections and / or Lötverbin- and / or terminal connections for connection cables, said sub-elements are electrically and mechanically connected to the line strip ends. For these compounds known measures can be used.

Appropriately, the surface of the heating foil is selected approximately corresponding to the surface of the first building board and the flat strip of conductors attached continuously from one narrow side to the other. The width of the line strips is preferably in the order of 15 mm.

For example, an electrically operable heating field or the sum of Teilheizfelder the Wandheizplatte or their Strahlungsheizungsbe- coating with a safe non-critical low voltage, preferably a safety extra low voltage of less than 42 volts, in particular 24 volts AC and a power of 100 watts to 300 watts, preferably operated from 120 watts to 200 watts and more preferably of 150 watts. Due to the second building panel in the sandwich arrangement of the wall heating plate, the surface pattern of the heating foil from Teilheizfeldern and line strips is covered and no longer visible. It is therefore proposed to apply on the visible side a laminating film and / or paper web on which such a surface pattern is modeled as a warning pattern with a warning that not nailed in the area of the surface pattern and / or not screwed and / or not be drilled so that Heating panels should not be damaged or short-circuited. In addition, an installation instruction can also be printed on such a laminating film and / or paper web.

Wandheizplatten, especially using plasterboard, z. B. by gluing and / or screws and / or rivets are connected to a wall surface.

Furthermore, insulating material for thermal insulation and / or sound insulation and / or heat storage material can be attached to the back of wall heating panels.

Reference to a drawing, a concrete embodiment of the invention is explained in more detail by way of example. Show it:

1 is a plan view of a side wall of a building space with two side by side laid Heizheizplatten,

2 is an exploded view of a wall heating plate to illustrate the sandwich structure,

3 is a plan view of a heating foil used,

Fig. 4 is an enlarged view of the area A of Fig. 1, and 5 is a side view of the area A of FIG .. 4

FIG. 2 shows a wall heating plate 1 according to the invention in an exploded view. The Wandheizplatte consists in a sandwich arrangement of a first plasterboard 2 - in the installed state at the back - and a second plasterboard 3 - in the installed state, for example, on the front side. Between the two plasterboard 2, 3, a heating foil 4 is embedded. In the finished production state, therefore, the first gypsum board 2, the heating foil 4 and the second gypsum board 3 are firmly joined together. The plasterboard 2, 3 each have a thickness of 3 mm, while the heating foil 4, however, is very thin, so that the overall result is a Wandheizplattenstärke of slightly more than 6 mm.

In Fig. 3 is a plan view of the heating foil 4 is shown, from which give more details. The dimensions given refer to preferred sizes.

The heating foil 4 and thus the entire wall heating plate have a length of 2500 mm and a width of 900 mm. The heating foil 4 consists of a carrier foil 5, on which an electrically operable heating field, consisting of six stacked Teilheizfeldern 6a to 6f is attached. The Teilheizfelder 6a to 6f consist of a radiant heater coating with a rectangular area of 750 mm in the transverse direction and of 260 mm in the high direction. The partial heating fields 6a to 6f are each separated by a non-heating transverse strip 7a to 7e with a width extension in the vertical direction of 40 mm.

The lowermost Teilheizfeld 6a is of a narrow side edge 8, which forms the lower narrow side edge 8 after a stationary installation of Wandheizplatte 1, by a non-heating space 9 by 600 mm upwards added. In the illustrated arrangements of Teilheizfelder 6a to 6f results in an upper non-heating space 10 with a height of 140 mm. In addition, with a width-wise arrangement of the partial heating fields 6a to 6f, a non-heating longitudinal strip 11a, 11b with a width of 75 mm in each case results on both sides.

The Teilheizfelder 6a to 6f have a thin-walled coating of an electrically activatable radiant heater coating, which may contain, for example graphite and carbon black and preferably emits a high proportion of infrared in the non-visible spectrum. On both sides of the Teilheizfelder 6a to 6f flat strip strip run as a copper strip 12a, 12b continuously from the lower narrow side edge 8 to an upper narrow side edge, said at the lower narrow side edge 8 on the copper strip 12a, 12b at line strip ends 17a, 17b connecting elements 18a, 18b as a connector Mounting parts or clamp connection parts are attached to the connection for connection cable 19 a, 19 b to a control and power supply unit, not shown. The copper strips are very flat and have a width of 15 mm. The Teilheizfelder 6a to 6f are designed so that they can be operated with a safety extra low voltage of less than 42 volts, in particular 24 volts AC and, for example, with a total power of 150 watts. With a power supply unit (power supply unit) for 24 volts AC and a maximum power of 300 watts, two such wall heating plates can be connected in parallel.

In the preferred use or laying in conjunction with a side wall structure, the wall heating plate 1 is placed with the lower narrow side edge 8 on the floor 13, as shown by two already laid wall heating plates 1, 1 'in Fig. 1. For further attachment to a side wall 14 of a building space, for example by drilling and screwing, the areas 9, 10 and the transverse strips 7a to 7e and the longitudinal strips 11a, 11b in which no radiation heating coatings are lie. On the visible side of the plasterboard 3 (not shown), the surface pattern corresponding to the underlying Teilheizfeldern 6a to 6f and copper strips 12a, 12b together with warnings that may not be screwed or nailed in the area of the surface pattern, printed.

The area dimensions of the lower first plasterboard 2 and the heating foil 4 are the same. The second plasterboard 3, however, is shorter by an edge offset 15. The second plasterboard 3 is offset from the lower narrow side edge 8 of the first plasterboard 2 upwards, so that a freely accessible return edge 16 is formed on the heating foil 4, with a free accessibility of the line strip ends 17a, 17b of the copper strip 12a, 12b. At the line strip ends 17a, 17b connecting elements 18a, 18b are attached.

For better clarification, the lower edge area A of FIG. 1 is shown enlarged in FIGS. 4 and 5 in a plan view and a side view. From Fig. 5 it can be seen that the lower portion can be covered with the return edge 16 after laying and the electrical connection simply by a (dashed line) skirting or skirting 20 corresponding height, in a wall-side recess of the skirting 20, the connection cable 19a, 19b and possibly other cables can be safely and concealed recorded.
