Description

construction and method for producing an electrical floor and / or Wall heating, in particular for concrete floors.

There are already known methods for building and manufacturing an electrical floor and wall heating. So will in the DE 10 2006 004 755 A1 a method for building an electric underfloor heating, fixing mat and floor structure described. In this case, in order to keep the assembly time for the formation of a floor structure with integrated electric floor heating low, a Fixiermatte having an upper support surface and not over the support surface protruding fixing elements for receiving a heating wire, laid on a bare floor over the entire surface. Subsequently, the heating wire is fixed in the desired heating areas on the fixing elements. Finally, the floor covering, in particular a tile or Steinplattenbelag applied. Tiling can be done without waiting immediately after placing the Fixiermatte and the laying of the heating wire. An application of a leveling compound is not required. In the DE 44 47 407 A1 a method for producing a mechanically strong, flexible composite layer is described as a low-voltage heating element for sheet-shaped temperature radiator and for a sheet-like flexible heating element. The object of this invention is to provide a flexible sheet as a heat radiating heating element in which electrical energy is converted into heat, to develop with a defined mechanical strength using fibrous or filamentary carbon modifications and with a resistance which does not change during use, wherein the supplied electric energy is converted into long-wave infrared radiation with only slight warming. This is inventively achieved by a method for producing a flexible laminar structure in that after designing a sheet-like dielectric textile support layer on this mechanically limited resilient fiber web consisting of electrically conductive fibers with a disordered arrangement of fibers in the form of a carbon fiber fleece and then another dielectric, consisting of a textile fiber web cover layer is applied and these are then needled together and thereby mechanically bonded together. The field of application lies in the production of a radiant energy converting to electrical energy, which is predominantly used as a floor covering. Furthermore, the describes DE 42 21 454 A1 a heating element made of electrically conductive fiber fabrics and a method for its production. This invention relates to a heating element of electrically conductive fibrous webs embedded in a curable synthetic resin and connected at opposite ends to a power source, the fibers being flattened at the fiber crossing points and the resulting fibrous web conductively connected via the web structure and points of contact is, as well as processes for its preparation by impregnating a fiber fabric with a curable synthetic resin, with a compression pressure of 100-1000 N / cm ² , preferably 500 N / cm ² , applied, the resin cures and optionally provides the resulting heating element with cover layers , The DE 24 35 594 A1 describes a heatable road surface with a heat-insulating base layer, an intermediate layer in which a heating element is embedded and with a surface forming the top layer, the heating element is a heating foil and provided with arranged at opposite edges contact bands and laid in adjacent tracks, said Heizfolienbahnen share the intermediate layer in a lower layer and a top layer and the evenly distributed on the intermediate layer surface interlayer sections are present, in which the upper layer is directly in contact with the lower layer.

task The invention is an electric floor and / or wall heating and the associated manufacturing process in particular to create concrete floors.

The Floor and wall heating according to the invention consists from a layer structure of an epoxy resin layer or polyurethane layer and an electrically conductive Heizleitschicht. The choice of Materials enable the use for soil construction as well as for the wall construction. In dependency of to be applied operating voltage is the thickness of the base and cover layer individually determined. By the invention Building up in layers results in the possibility of this Build up to complete more layers by adding in another Layer a visual design element on the electrical Heizleitschicht is applied. This layer is completed by a final Epoxy resin layer or polyurethane layer sealed. Thus, can effectively a floor and wall design done, which through the seal against external influences is largely protected. The comparatively small Effort of implementing the method allows the application as well on roads also later. The process can do this also be applied directly on the roadway. The scattering of Quartz sand ensures that for a roadway necessary grip of the vehicle wheels especially at Wet.

Advantageous embodiments of the structure the floor and wall heating are shown in claims 2 to 9. Advantageous embodiments of the method are shown in claims 11 to 14. Claim 15 as a secondary claim of the method also allows the heating of lanes, which can be used in particular application to underground car park applications. According to claim 2, the electrical Heizleitschicht can also be applied according to a continuous pattern. Thus, material is saved for the Heizleitschicht and it can be heated individually specific areas. In the development according to claim 3, the electrical Heizleitschicht consists of one layer and / or more layers and / or partially distributed multiple layers, also thereby different areas can be heated differently. According to claim 4 electrical contact points are provided at any point for electrical contacting. This also serves for the individual heating of special floor or wall areas. In the development according to claim 5, a visual design image is provided under the top cover layer. This image serves as well as the thermochromic admixture in drawing or image form according to claim 6 special advertising effects. The use of Bodeneinlässe or wall distributions according to claim 7 simplifies the electrical installation. According to claim 8 cardboard, films or plates can be prefabricated with an electrical Heizleitschicht that allows quick installation of floor or wall heating. According to claim 9 can be used as operating voltage, a low voltage or the normal household voltage and this as AC voltage or DC voltage.

at The development of the method according to claim 11 in step 2 on the entire area or partially distributed more applied electrical Heizleitschichten, wherein after each application of a a further layer of curing, which is characterized by the different thicknesses partially and horizontally different electrical Heizleitschichtdichten and thus different resistance values result and thereby different power outputs thermal Energy and thus different temperatures result. An area is thus in areas of low warming and in areas higher Warming divisible and with at least one energy source operated. With the development according to claim 12 are in step 2 before applying the electrical Heizleitschicht a self-adhesive Foil with an uninterrupted, cut pattern on the in step 1 on a ground applied epoxy resin layer or Polyurethane layer applied and the electrical Heizleitschicht applied flat on the self-adhesive film. With the Pattern becomes the area in areas of higher and lower electrical Heizleitschicht divided and thereby short or long Heizleitschichtlängen formed. Consequently the resistance value is varied according to length and density and it can thereby be personalized on the surface distributes different power outputs of thermal energy and thus different temperatures can be achieved. In the training According to claim 13, the electrical Heizleitschicht covering Epoxy resin layer or polyurethane layer with a thermochromic Added in the form of characters or images. hereby result in visual design options on walls and floors and also an indication of the function of the electric Heater. A similar object is achieved according to claim 14, in which on the Heizleitschichtmaterial a visually design Element is applied, which still by an epoxy resin layer or polyurethane layer is sealed.

The electrical heating conductive layer 3 becomes flat on the self-adhesive foil 7 with the pattern cut out 5 After that, the self-adhesive film is applied 7 removed again and thus are on the epoxy resin layer 2 only structures as tracks 4 from Heizleitschichtmaterial left over. After curing of the tracks 4 become the contact points 5 positioned and in distribution points 6 merged. In step 3 becomes the electrical Heizleitschicht 3 So the tracks 4 covering epoxy resin layer 2 or polyurethane layer 2 applied and cured.

In particular, desired advertising effects, the electrical Heizleitschicht 3 covering epoxy resin layer 2 or polyurethane layer 2 be provided with a thermochromic admixture in the form of characters or images.
