" Heatable and coolable structural layer" .

The invention relates to a heatable and coolable structural layer, those arranged on a solid construction substrate, e.g. a concrete layer, and on one or more above the construction substrate Layers for thermal insulation as well as for moisture barrier is to be applied, the building structure layer being one of a water set Includes pipe system to be flown through on all sides.

All previously known structural layers of the above type had the disadvantage that their pipe system was only able to heat the structural layer linearly, which had to be dampened by a correspondingly large layer thickness above the pipes to achieve a reasonably uniform surface heating. However, this in turn resulted in considerable thermal inertia in the building layer for the heating operation, which in turn meant that impairments to the degree of comfort were unavoidable. Furthermore, such thick structural layers were expensive, due to their high weight, disadvantageously compressed the thermal insulation layers underneath and also increased the construction costs of the entire subsurface, which accordingly had to be dimensioned larger ₀

The invention has now set itself the task at completely to create a building structure layer of the aforementioned type with a uniform surface temperature, which with a thin layer

thick has such high flexural, breaking and compressive strengths that it is possible to use a layer thickness above the pipes which was previously prescribed by the standard with at least 35 now will get by with just 35 mm and less

According to the invention, this object is achieved in that the pipeline system is attached to a reinforcement mat and the reinforcement mat is embedded on all sides in the structural layer by means of spacers to the subsurface. In this way be obtained even at a stigkeiten including Ge layer thickness of 50 mm such a high Fe-W, that the thus constituted structure layer can meet all the requirements.

It should be mentioned at this point that there is already a structural layer is known with a welded wire mat, on which a heating cable system consisting of resistance wires is used for heating is attached, which is embedded in a screed layer. Here, the welded wire mesh is applied after a certain screed layer thickness that has not yet set in several places with short, jerky luffing movements into the building structure pulled j whereby on the one hand an uneven embedding the reinforcement mat and the heating cable system in GDR screed layer and, on the other hand, damage to the cable system was inevitable large thickness of the building structure layer, which is necessary for heat storage, does not have a reinforcement function, but only a mounting template for the radiator system.

The building layer is heated or cooled advantageously by means of a pipeline system that consists of a

known spiral pipe or pipe coil, preferably from There is plastic, whose flow channels of equal size are parallel are arranged to each other and are to flow through in the counter flow of a hot or Kühlwassersatζ, the flow channels of the flow and return have a common area for direct heat exchange over their entire length. This creates a completely uniform surface temperature of the building structure layer achieved and thus ensures a uniform thermal expansion of the entire layer, creating cracks within the building structure layer be avoided. At the same time, the building structure is now thermal with a completely uniform surface temperature considerably more flexible than all known structural layers that are also provided with a pipe system.

The spacers for the welded wire mesh are advantageously made by several noses or lugs bent out of the welded wire mesh. Formed webs, which are preferably provided with pressure plates «As a result of the complete embedding of the welded wire mesh achieved in this way in the building structure it has an effective reinforcement function. It also needs to fix the piping system no longer cumbersome and time-consuming by means of appropriately designed pipe clamps, straps or the like Work to be raised. Another advantage of this arrangement is that now the welded wire mesh, in particular if they are used to dampen local overheating - insofar as this can occur at all with the aforementioned pipe system - should serve, no longer in direct contact with the layers below it for thermal insulation and moisture barrier stands, but now by a thin and thermally conductive, However, in a certain way, the insulating building structure layer is also separated from it.

The building structure layer reinforcement can be reinforced on all sides by a second reinforcement above the pipeline system embedded reinforcement mesh «, an increase in strength and an avoidance of shrinkage cracks can also be achieved be that the structural layer is provided on its surface with cut joints, which are preferably those in the Structural layer embedded pipes cross or by the fact that the structural layer, especially if they are laid outdoors wwrden, on their surface with embossed stiffening ornaments is provided.

It has proven to be particularly advantageous technically and economically a building structure with a total height of less than 65 mm exposed, in the heating or cooling pipes with an outer diameter from 20 - 22 mm and a reinforcement mat with a wire diameter between 2 - 5 mm is embedded, with the lower level the reinforcement mat arranged below the pipes is at a distance of at least 3 mm from the underside of the building structure.

In Fig. 2, the material layers 6, 7 and 8 are common Layer 9 summarized, either connected to the structural layer 1 to form a compact structural layer or can be separate from it. It is essential that this layer 9 has good properties both in terms of impact sound and thermal insulation as well as vapor and moisture barrier as well as the compressive strength. In Fig. 2 there is also a cut joint 1 'in the structural layer. indicated, which can be pulled into the still damp screed, for example, by means of a trowel tip.
