Description

The invention relates to a surface tempering element.

The invention relates to a surface tempering structure with a support layer, in which a Temperierungsleitung is integrated.

Such surface temperature control structures have been state of the art in the field of wall and floor heating for many years. There are numerous systems on the market, where various board materials (EPS insulation boards, screed, gypsum fiber boards, plasterboard, brick walls, etc.) are provided with grooves or depressions in general, in which Temperierungsleitungen are introduced. The lines are usually covered by a cover plate (plasterboard, gypsum fiber board, cement fiber board, porcelain stoneware, natural stone, screed elements, etc.) or a sealing compound (plaster, screed, thin screed, filler etc.). This serves on the one hand to achieve an attractive appearance, without seeing the lines, on the other hand, the heat must be transferred from the line to the surface structure, to which the heat conduction from solid to solid body is suitable.

In DE 20 2005 002 322 U1 such a system is shown. Depending on the application of the plate, z. B. in the field of flooring, it is important to the line at a defined location, eg. B. to fix at the bottom of the depression. Fixed there, the line after filling the groove by a defined coverage with filling material is protected (eg, before Stuhlrollenbelastung). In the described system, the fixation is provided by a constriction in the upper part of the groove. The groove with bottleneck is technically usually made with a router with appropriate tool, usually with diamond blades. Since the bottleneck must be designed with very tight tolerances, after tightening the tool, the constriction is too narrow for the line to fit through. Now you have to mill both flanks of the groove extra (milling two contours), which means twice the workload, or you have to equip the tool very often with new cutting, which is extremely expensive with diamond tools.

Furthermore, there is the risk of damage to the pipe when pressing the pipe through the bottleneck, especially in undersize. In practice, the pipe is partially hammered in, which can be very detrimental to the pipe and means a considerable installation effort. Many tubes have an oxygen barrier layer as the outermost layer, which can be damaged very quickly. In addition, pipes can fail due to scratches, which represent a notch on brittle fracture. The tube diameter and groove width also leave only a very narrow gap left and right free. When filling the groove with filling compound cavities can thus form next to and below the pipe, which negatively influence the mechanical stability, in particular to compressive stress (eg chair roller) and, in extreme cases, can lead to failure of the heat carrier. Cavities further prevent good heat conduction, since air gaps represent a significant thermal resistance here.

In EP 2 105 675 A2 is also shown such a system that is opposite to the system DE 20 2005 002 322 is improved. Thus, the diameter constancy of the tool for making the bottleneck is not required, there is no bottleneck for fixing the tube. Since the tube is mutually fixed by the flanks by a groove with undercut, executed in the form of an elongated offset geometry (serpentine line). But even for this system, a milling tool in special design (pear shape), usually with diamond sheath needed. Such special tools usually cost twice to three times a standard end mill / milling cutter. Also, the sharpening costs or repair costs (at cutting edge loss) are significantly higher, compared to standard tools. Another disadvantage of this system is the comparatively large free cross section of the groove. It is required for filling a lot of filler, which means on the one hand comparatively greater costs and also leads to more shrinkage, as with a smaller cross-section. This can mean additional rework and costs.

The invention is based on the problem of specifying an improved surface temperature control element on the other hand.

To solve the problem, a surface temperature control element is provided according to the invention, comprising a carrier layer with at least one introduced in the surface groove or groove-like depression for receiving a Temperierungsleitung in the recess via one or more, in the depression force and / or form-fitting fixed fasteners is fixed.

The present invention provides a surface temperature control element which is provided with a carrier layer and an integrated temperature control line. A surface tempering structure consists of a plurality of juxtaposed, mutually connected surface temperature control elements, the support layers complement each other and their grooves adjoin one another, so that the line can be laid over a large area. Each element has a planar milling geometry, which can be combined and so in the overall structure arbitrary circuit configurations, eg. B. the known laying in meandering, spiral, Doppelspirallayout, as well as their combination and different installation distances allows. Common here are elements that have a special design of the edge for exact positioning and connection. Numerous connection options such as groove-groove with foreign spring, tongue and groove, seam fold, butt-stump with flat dowel, dowel with dowels, etc. are state of the art. The formation of the edge is only of secondary importance for the surface tempering structure. The surface tempering structure no longer has the disadvantages of the systems presented above and leads to significantly lower costs with the same technical performance data, with regard to the core properties such as strength and thermal performance (heating capacity, cooling capacity).

By tempering is meant that the structure is used in particular for heating or cooling, d. H. Heat energy is supplied or removed via the heat transfer medium flowing through the inserted pipe, pipe, hose etc. The heat transfer medium is usually water, but may also be a water-glycol mixture, oil or another heat-transferring liquid.

Under depression is understood to mean a surface which is below the surface but accessible from the surface or back surface. This can be a groove, groove or generally a recess with a variety of cross-sectional configurations. However, this recess, hereinafter also generally described as a groove, is always made by a tool with a vertical or slightly deviating from the vertical axis of rotation, usually with a router.

In the carrier layer grooves are introduced, which receive the Temperierungsleitung. The formation of the recess can be made in the simplest case with a standard groove cutter. It then has three straight flanks, so for example has a square or rectangular shape.

In order to avoid stress peaks in the panel material and associated static disadvantages (reduction of strength, tendency to crack), it is recommended that the sharp-edged inner corners be rounded. This also reduces the consumption of filling compound with which, as an option, the groove can be poured out after inserting the temperature control line.

In the upper part of the groove, a small bulge can be attached, which is the only point of contact for this when inserting the tube. The process of insertion is thus positively influenced because in particular round, bulbous bulges reduce the resistance by friction and the usual hooking of the tube. Another aspect may be the reduction in fill mass consumption. For the fixation of the tube, this training is not important.

The groove can be formed deeper in the transition region between the individual surface elements. This has the advantage that any adhesive necessary for joining the individual elements, which emerges from the adhesive joint, does not influence the position of the pipe.

Likewise, the groove may have short offsets at certain intervals in the longitudinal direction in order to hold the tube in the center by the bulges formed in this way. The clear distance between the bulges is always greater than the pipe diameter in order to always insert this easily.

Central part of the patent is the attachment of the tube in the groove by explicitly attached fasteners. These can already be attached to the individual surface element before the insertion of the pipe, factory or on site. Likewise, an embodiment is possible in which the fastening elements after introduction of the pipe, then usually on site, are attached. Advantage of this solution is that the installation of fasteners z. As clips, springs, stirrups, brackets, etc. is significantly cheaper than the elaborate rework, as in the elements in the prior art, the case. Simple is also the assembly, since the fasteners are clipped into the groove or pressed only to fix them in particular by clamping and so set the line. Depending on how long the groove is on the respective surface tempering element, the number of fastening elements to be set is selected. Since the fasteners are fixed very firmly on the press fit or the force or positive interaction with the groove walls, relatively few fasteners per unit length of the line are required so that the groove is open over almost the entire length and if necessary with a filler can be completed without the cavities remain. The fasteners can be made of different materials, eg. As plastic, steel, spring steel, aluminum, wire, wood, etc. exist.

The groove with tube can be filled in certain cases with a liquid, hardening mass, in order to ensure the best possible heat transfer, but not necessarily. So the filling z. B. in subsequent application of covering layers (eg, stone, porcelain stoneware, etc.) omitted, since in this case the heat transfer through the adhesives for fixing these layers fulfills this task. Ie. a tile adhesive can as Heat bridge between tile and pipe act. Alternatively, the groove with tube can also be filled with stable, pasty, thixotropic or molten materials.

In order to be able to fully enclose the tube on both sides when using flowable filling compounds, evenly spaced gaps or openings, if necessary at repeating intervals, are favorable on both sides. Alternatively, you can form extensions to the left and right of the pipe, which incorporate a liquid filler mass. It may also be advantageous to form the groove with slight offsets at intervals in such a way that the tube is located relatively centrally in the groove due to the resulting lateral support points.

The connection of the line from the surface structure to the respective connection point, z. B. a manifold or Heizkreisverteiler can also be done in the area structure, in which case the groove leads to the connection point. For systems with available cavity below, behind or above, the connection via the Anbindeleitung located in the cavity offers. For this purpose, the groove is deepened so far punctually that a breakthrough to the other side arises. Ideally, the recess is arcuate, wherein the opening can be made to the other side, or a thin layer stops. So this version can be installed in several places and breaks this predetermined breaking point, where then actually the pipe should be performed. Advantage of the installation of Anbindeleitungen in the cavity is that when activating the heating or cooling not unwanted foreign surface sections become thermally active. Unintentional thermal influences as well as temperature stresses, which could lead to damage to the structure, are thus reliably avoided, as can component joints can be crossed easily.

As described above, the surface tempering structure consists of a plurality of adjacently arranged tempering elements of the type described above. The structure can be part of a floor, wall or ceiling tempering or construction, in particular floor, wall or ceiling heating and / or cooling ,

In this case, the structure can form a floor, which rests flat on a supporting layer. Alternatively, the structure may form a floor which rests on individual supports or linear bearings, so that an underlying cavity is formed.

When used in the wall and ceiling area, the element or the structure can form a wall, a wall panel or a ceiling element.

The Anbindeleitung the surface tempering structure may lie lying in this lying to the connection point or lead in the cavity below, behind or above the surface to the connection point.

The backing layer of each panel tempering element may be calcium sulfate screed, cement screed, gypsum board, gypsum fiber board, cement fiber board, dry hollow bottom board, chipboard, wood-based board, mineral bonded board, porous board with foamed inorganic components, plastic board, rigid foam board or similar board material suitable for wall, floor, ceiling. This list is not exhaustive.

The inner corners of the groove on the groove base may be rounded, which is readily possible when producing the groove by means of a milling cutter. The groove itself is designed to accommodate pipes with almost any diameter, especially for pipe diameters of 8 to 30 mm. The tube should be relative to the depth of the groove or the thickness of the material relatively close to the surface of the element or the structure, in particular 0 to 10 mm away from the surface.

Further, the groove in the upper region along a bulbous or angular shape have, which jump into the groove.

Finally, the groove can be closed after introduction of the line with a filling compound, in particular with a mortar, filler, wax or resin, and this list is not exhaustive.

In order to achieve an optimal product, the mentioned training features can be used in any combination.
