BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a heated floor construction comprising a supporting or existing floor construction, a number of components of a sheet material, at least one heat dissipating means in the form of an electrical heating cable, and a device for regulating the heat dissipation of the heating cable, said heating cable being disposed in at least one channel between the different sheet components, said channel or channels having a width which is adapted to the largest diameter of the electrical heating cable, and said sheet components having a width which approximately corresponds to the predetermined cable spacing (cc-distance) minus the greatest diameter of the heating cable, the corners of the sheet components at those ends where the heating cable changes direction, being bevelled or cut-off.
BACKGROUND OF THE INVENTION
Heated floors are previously known in a number of different forms, for example a plaster netting can be laid on top of the supporting structure and be fixed to the surface of the floor structure by glueing, for example. The electrical heating cable is then fixed to the plaster netting, first being laid out in a loop pattern and then being fixed by hot melt adhesive to the plaster netting. When the electrical heating cable has been completely laid out, it is covered with a plastering material in such a manner as to cover completely. The covering plaster is then allowed to dry and is then provided with an adhesive for laying, so-called clinker. The disadvantages of these methods are the risk of having the wrong cc-distance between the heating cables, a too small bending radius which involves the risk of cable breakage in addition to the fact that laying, drying and curing take a long time before the electrical heating cable can be used, usually one month. Similar constructions are also available where the electrical heating cable has been replaced by water pipes, for example PEX-piping.
The purpose of the present invention is to create a heated floor construction which is simple to install both for new construction and renovation.
An additional purpose of the invention is to provide a heated floor construction which is suitable for laying on a floor with a high moisture content, e.g. a concrete slab which absorbs ground moisture.
SUMMARY OF THE INVENTION
The heated floor construction according to the invention is characterized in that the channel or channels are limited below by the supporting or existing floor construction, that the sheet components consist of transverse sheet components and/or longitudinal sheet components, which are laid out and fixed to the supporting or existing floor construction in such a manner that the heating cable can be laid directly in the channel or channels as a single loop or be divided into a plurality of different loops, that the sheet material has a thickness, which approximately corresponds to the greatest diameter of the heating cable, and that a surface material is disposed on the upper surface of the sheet components.
The heated floor construction according to the invention makes possible more rapid, more effective and simpler laying and immediate use, since no time is required for drying of any component material. The floor construction makes it possible to make the applied heated layer relatively thin, i.e. suitably 18 mm and thicker. A relatively thin applied layer provides relatively low thermal inertia, which can be increased by placing spacer material in the floor construction which would then serve as an extra heat depot.
The construction comprises transverse sheet components and longitudinal sheet components which, depending on the shape of the room, can form either a right angle or another angle. Channels are formed between the sheet components, in which an electrical heat cable is laid. The sheet components are bevelled or rounded at the corners, where the heat cable changes direction and the heat cable is guided around the corner with the aid of a corner piece placed radially outside the corner, which
