Abstract

The invention relates to a floor (1, 2, 17, 19, 23, 28, 40) that can be used as a heat storage mass for a heating or cooling system and comprises a concrete layer (3, 32) penetrated by a pipe by means of grinding.

Description

floor ceiling

The invention relates to a floor slab which comprises a concrete layer and can be used as a heat storage mass of a heating or cooling system.

In the so-called "concrete core activation", the heat storage mass of the concrete layer of a floor slab is used to heat and cool rooms in a building. In the central height range of the concrete layer to heat carrier pipe loops are attached. In an exemplary typical mode of operation, the pipe loops are run through with cool water at night to cool the concrete. During the day, the cooled floor slab counteracts the daily warming in the room below and can thus relieve or replace an air conditioning system. The pipe loops are usually formed by a relatively stable plastic hose. In the usual method of production, pipe loops are clamped to the previously arranged steel reinforcement and then the arrangement is cast in situ concrete. An example shows the document DE 10312844 B3. An advantage of this design are the low material costs. Disadvantages are the extreme inertia of the heating or cooling effect and the low heating or cooling capacity.

CH 387258 A and CH 414994 A show plate-like elements which can serve as lost lower formwork of in-situ concrete slabs and on their underside - ie where there is no concrete as intended - have channels in which pipes run for a heat transfer fluid. In the ceilings thus formed, the heat storage mass of the concrete core of the ceiling is not used, so they have no concrete core activation; Instead, like ceiling heating systems or ceiling cooling systems, which are arranged on a suspended ceiling, they are more thermally dynamic and also more efficient.

The AT 414000 B shows the use of a retaining rail system for pipe grinding of a solid concrete floor. Even in a factory pipe loops and retaining strips are joined together so that flat lattice mats are formed in which the pipes are predominantly normal to the retaining strips. To form a ceiling such mesh mats are placed on the building site from above on the slab formwork, the pipe loops of each grid mats connected together, and then surrounded the entire assembly with concrete. Through the use of many such support rails can be achieved that the pipe loops are kept in rather small, well-defined distance to the bottom surface of the ceiling. Due to the arrangement of i Pipe grinding in the lower height range of the ceiling instead of in the middle height range when used as a ceiling heating or ceiling cooling, the thermal inertia is lower and the performance per ceiling area higher. Disadvantages are relatively high costs related to the use - in particular caused for the work on the construction site - and difficulties in small or crooked areas to equip a high proportion of the ceiling surface with pipe loops.

The object of the invention is based on a floor slab, which has a concrete layer which is traversed by grinding a heat transfer fluid pipe and is intended to serve as a heat storage mass of a heating or cooling system to perform so improved that the design for Ziegeleinhängdecken is applicable that compared to the design with mid-level pipe loops per time, a higher amount of heat can be stored or supplied, and that compared to the construction according to AT 414000 B, the amount of work for the production is reduced, in particular less effort for bonding incurred by pipe sections.

For solving the problem is based on the known construction, in which runs in the concrete of the ceiling a heat transfer fluid pipe. As an improvement according to the invention, it is proposed that, in addition to the said pipe, a heat conduction profile is covered by the concrete layer, the heat conduction profile being parallel to the ceiling plane and parallel to the pipe and lying flat against the outer surface thereof and projecting radially away from the profile surface regions.

The heat conduction profile greatly increases the area over which heat is transferred to and from the concrete layer. This achieves faster heat transfer between the heat transfer fluid and the concrete layer. Due to the heat conduction also ensures that the construction of the heat transfer fluid pipe no longer must be completely enveloped with in-situ concrete. As a result, particularly simple constructions can be realized, in which the heat carrier fluid-carrying pipe is arranged very close to the lower surface of the floor slab. Above all, pipes which have a comparatively very large diameter can thus be arranged very close to the lowest surface of the floor slab. There are also smaller sections between adjacent pipe sections feasible. This results even if the specific thermal conductivity of the material of the Wärmeleitprofils is lower than that of the concrete layer, a better heat exchange between the space to be heated or cooled and the pipe carrying heat-transfer fluid, as would be possible without a heat-conducting profile.

In a preferred embodiment, the heat-conducting profile protrudes with a part of its lateral surface on or over the lower surface of the concrete layer.

Thus, heat can be quickly exchanged between the under the ceiling located to be heated or cooled space on the one hand and the guided in the pipe heat transfer fluid on the other hand bypassing the concrete view. This allows the temperature in the room located under the floor ceiling to be adjusted more quickly. The effect is stronger, the more surface of the Wärmeleitprofils protrudes from the concrete layer and the better heat-conducting properties has the Wärmeleitprofil.

In a preferred embodiment, the Wärmeleitprofil a Rohraufnahmut, which has approximately the cross-sectional shape of a circular section, and in which the pipe of the pipe loops can be clamped.

In a particularly preferred embodiment, the heat-conducting profile protrudes with a part of its lateral surface on or over the lower surface of the concrete layer and has the Wärmeleitprofil a Rohraufnahmut whose open cross-sectional area side is above.

This enables particularly efficient work on the construction site. The Wärmeleitprofile can be placed on top of the lower slab formwork, - or even be used as slab formwork (or part thereof) -, and then can be easily pressed from above the pipe for the pipe loops in the Rohraufnahmut. The pipe can run "endlessly". In the longitudinal region between two tube receiving grooves, it only needs to be curved from the front end of a tube receiving groove to the frontal "beginning" of the next tube receiving groove. This eliminates separate coupling points between pipe sections.

The invention is illustrated by means of drawings:

1 shows a vertical sectional view through a first exemplary floor slab 1 according to the invention.

FIG. 2: shows, in the same view as FIG. 1, a second exemplary floor slab 2 according to the invention. 3 shows a side view of a partial profile of the heat conduction profile used in the floor slab 2 of FIG. 2.

FIG. 5 shows, in the same view as FIG. 1, a fourth exemplary floor slab 19 according to the invention.

FIG. 6: shows, in the same view as FIG. 1, a fifth exemplary floor slab 23 according to the invention.

FIG. 7: shows a vertical sectional view of the lower parts of a sixth exemplary floor slab 28 according to the invention, with a viewing direction parallel to the profile direction of the heat conduction profiles.

FIG. 8: shows, in the same view as FIG. 1, a seventh exemplary floor slab according to the invention.

FIG. 9: shows, in the same view as FIG. 1, an eighth exemplary floor slab 40 according to the invention.

The floor slabs 1, 2 according to FIG. 1 and FIG. 2 have a concrete layer 3 which is reinforced by two layers of reinforcement 4 (structural steel mesh). The viewing direction in Fig. 1 and Fig. 2 is in each case parallel to the longitudinal direction of the loops in which that tube 5 is placed, which in normal operation by a heat transfer fluid - typically water - flows through. The tube 5 is typically a plastic tube.

The example of FIG. 1, the loops of the tube 5 run along the bottom of the lower layer of the reinforcement 4 along. In each case two mutually adjacent strands of the tube 5 are held by the same Wärmeleitprofil 6, each by a strand is held in one of two tube receiving grooves 7 of the Wärmeleitprofils 6.

The cross-sectional shape of the Rohraufnahmut 7 is approximately a circle portion, wherein the associated center angle is slightly larger than 90 °, so that therefore the maximum width of the Rohraufnahmut 7 is greater than the width of their opening area. The tube 5, whose cross-sectional area has a circular outer contour, is clamped in the tube receiving groove 7. In order for a tube 5 to be able to be introduced into the tube receiving groove 7, the two groove flanks have to be temporarily bent so far - or the tube 5 is temporarily deformed somewhat oval - that the width of the opening surface of the pipe receiving groove 7 is sufficiently large that the tube 5 can be squeezed through. In the elastically undeformed state, the outer diameter of the tube 5 is ideally slightly larger than the inner diameter of the Rohraufnahmut 7. This ensures that the tube 5 is fully applied after assembly under slight pressure to the boundary surfaces of the Rohraufnahmenut 7 and thus facilitates loose heat transfer to each other becomes.

In order to be able to comply with its purpose of heat transfer, the material of which the heat-conducting profile 6 consists-in the construction according to FIG. 1 and FIG. 2-a better specific thermal conductivity than the concrete of the concrete layer 3. If the pipes 5 are rather far inside (high) lie in the concrete layer is the Wärmeleitprofil 6 typically made of steel or aluminum. In addition to the two areas of the Wärmeleitprofils 6, each comprising a Rohraufnahmenut 7, the Wärmeleitprofil 6 has two connecting webs 8, and a protruding from the concrete layer 3 plate 9, whose plane is parallel to the floor of the floor 1, and which above all the Heat exchange with the adjacent to the bottom of the floor ceiling 1 space serves.

The connecting webs 8 each connect a region comprising a tube receiving groove 7 to the plate 9.

In the example sketched in FIG. 1, the lower surface of the concrete layer 3 in the region between adjacent heat-conducting profiles 6 still springs back upwards. In concrete-free space between two adjacent two Wärmeleitprofilen 6 a strip 10 is clamped from sound-absorbing material 10, the free surface is flush with the plates 9 of the Wärmeleitprofile 6.

Ideally, both Wärmeleitprofile 6 and the sound-absorbing material 10 are placed on the construction site on top of the slab formwork, then the tube 5 is clamped in the Rohraufnahmenuten 7, then the probation 4 is arranged, and finally in-situ concrete is poured which cures to the concrete layer 3 ,

2, the tube 5 is in the height range between the two layers of the reinforcement 4. The Wärmeleitprofil 11 is assembled in this case of three individual sub-profiles, namely an outer sub-profile 12 and two plugged thereon inner sub-profiles 13th The outer partial profile 12 is essentially a U-profile whose base surface is flat and in this case is flush with the lower surface of the concrete layer 3. The two flanks of the outer sub-profile 12 projecting from the base surface into the concrete layer 3 are interrupted by a grid of slots 14 (FIG. 3) which, in cross-sectional view, protrude from the free ends to the base surface. The slots 14 are required so that rods of the lower layer of the latticed reinforcement 4, whose plane intersects the flanks of the outer sub-profile 12, may pass therethrough.

The two inner sub-profiles 13 each have a pipe receiving groove 7 again. Furthermore, they have a slim narrow groove 15, in which the free ends of the flanks of the outer sub-profile 12 are inserted and hold force-fit therein.

The construction of the floor slab 2 according to FIG. 2 is somewhat more complex than that of the floor slab 1 of FIG. 1. However, it is more advantageous in that the heat storage capacity of the entire concrete layer 3 is better utilized, and that the pipe 5 is better protected against damage by drilling is. However, the dynamics are slower and the performance in terms of heating or cooling effect to the lying under the ceiling 2 space down.

The floor slab 2 according to FIG. 2 has, on its underside, a thin cover layer 16 which is advantageous for optical reasons and which covers both the concrete layer 3 and the base surface of the outer sub-profile 12. The cover layer 16 is typically formed by gluing a net and filling.

Fig. 4 shows a floor slab 17 according to the invention with Wärmeleitprofilen 18 which typically consist of sheet steel, and are below the lower level of the reinforcement 4 and can form a support for this in construction. The pipe receiving groove 7 in this case is so deep that the pipe 5 lies very close to the lowest surface of the concrete layer 3. In order for a fairly rapid heat transfer between the heat transfer fluid in the pipe 5 and the lower surface of the concrete layer 3 is achieved and also a good cooling or heating power. In the laterally bounded by the distance between two adjacent Wärmeleitprofilen 18, downwardly open groove, in turn, a strip 10 is held from sound-absorbing material. Both the strip 10 and the Wärmeleitprofile 18 can be placed on the construction of the formwork for the ceiling before in-situ concrete is poured. Fig. 5 shows a floor slab 19 according to the invention with Wärmeleitprofilen 20 which typically consist of concrete, preferably fiber concrete or high-density concrete, and are below the lower level of the reinforcement 4 and can form a support for this in construction. In this case, the tube receiving groove 7 is so deep that the tube 5 is flush with the bottom surface of the concrete layer 3 - which is covered by the heat conducting 20 - lies. Despite the fact that the material of the Wärmeleitprofile 20 is not as good heat conducting as a purely metallic material - and in extreme cases may even have a lower thermal conductivity than the concrete layer 3 -, thus a fairly rapid heat transfer between the heat transfer fluid in the pipe 5 and the lower Surface of the concrete layer 3 and a good heating or cooling performance achieved.

The Wärmeleitprofile 20 thus form spacers between the lower surface of the floor slab 19 and the heat transfer fluid-carrying pipe 5. By this spacer, it is possible very well defined the tube 5 very close to the lower surface of the floor slab 19. Without the use of a thermally conductive profile arranged on the side of a layer of in-situ concrete, the pipe 5 would have to be arranged much higher above the lower surface of the floor slab, which would in any case significantly lower heat transfer between lower ceiling surface and pipe 5.

The lateral, mutually contacting edge regions of adjacent Wärmeleitprofile 20 are formed as entanglement between an extension 21 and a projection 21 from above encompassing hooks 22. The arrangement of Wärmeleitprofilen 20 thus formed may itself already serve as a lower formwork of a poured from in-situ concrete floor slab.

By the Wärmeleitprofile 20 itself consist of concrete or a comparable bound by cement material, there is a particularly good connection with the concrete layer 3 and advantageous properties of the lower surface of the floor ceiling 19th

Preferably, the material of the heat conducting profiles 20 contains additives, such as e.g. metallic fibers or iron filings, which improve the thermal conductivity compared to a purely mineral design.

More preferably, the material of the Wärmeleitprofile 20 is highly compressed. Compared to porous material, the specific thermal conductivity is thus improved. Also, Fig. 6 shows a floor slab 23 according to the invention with Wärmeleitprofilen 24 typically made of concrete, preferably fiber concrete, preferably compacted, and are below the lower level of the reinforcement 4 and can form a support for this in construction. The pipe receiving in turn is so deep that the tube 5 is flush with the bottom surface of the concrete layer 3, which is covered by the heat conduction 24.

The lateral, mutually contacting edge regions of adjacent Wärmeleitprofile 24 are formed in this case as interlocking teeth. Also, this arrangement of Wärmeleitprofilen 24 can even serve as a lower formwork poured from in-situ concrete floor slab.

The Wärmeleitprofile 24 have downwardly open channels, in which strips 10 are arranged from sound-absorbing material.

Fig. 7 shows in addition to tubes 5 and brackets 26 very flat Wärmeleitprofile 27 which in turn preferably from a cementitiously bonded material such as concrete, preferably fiber concrete, preferably containing metallic additives exist. The lateral, typically metallic elastic clamps 26 connect adjacent, laterally abutting Wärmeleitprofile 27 by clasping from these upwardly projecting extensions from above. By protrude upward projections with "overhanging" wall areas, in addition to the adhesive bond also results in a positive connection with a aufzuschießenden to the heat-conducting 27 Ortbetonschicht.

Fig. 8 shows a floor slab 28 according to the invention, which is formed as Ziegeleinhängdecke.

The statically essential elements are a ceiling support 29, suspended thereon ceiling tile 30, a reinforcement 31 and a concrete layer 32nd

As with conventional brick curbs, work on the site includes the following stages: - Laying the ceiling beams 29 on the bounding walls so that the ceiling beams 29 are parallel to each other in a predetermined by the dimensions of the ceiling tile 30 distance.

- Laying ("hanging") of the ceiling tiles 30 on the ceiling beams 29 from above, so that a ceiling tile 30 bridged the distance between adjacent ceiling beams 29 arranged parallel to each other and fed with each of its two Einhängvorsprünge 33 on each one of two adjacent ceiling beams 29 above rests.

- Arranging the reinforcement 31 above the ceiling beams 29 and the ceiling tile 30th

- pouring in situ concrete on the arrangement formed in the previous stages, so that the in-situ concrete envelops the reinforcement 31 and forms the concrete layer 32 after it has hardened.

According to the invention, a heat-conducting profile 34 extends in the floor slab 28, wherein the heat-conducting profile 34 is at least partially covered by the concrete layer 32, wherein the heat-conducting profile 34 rests flat against the outer jacket surface of the heat carrier pipe 5 and protrudes radially away from the latter with profile surface areas.

The tube 5 extends in loops above the ceiling beams 29 parallel to these and then around the end faces of rows of ceiling tiles 30 around. Ideally, it is pressed before attaching the reinforcement 31 in the already laid ceiling support 29.

Wärmeleitprofil 34 and tube 5 are connected to each other in surface contact and mechanically connected by the tube 5 sections in the Rohraufnahmenut 7 of the Wärmeleitprofils 34 runs.

In order to be able to meet its purpose of heat transfer, the heat-conducting profile 34 is typically made of steel or aluminum. In addition to the area comprising Rohraufnahmut 7 it has connecting web 35, and a plate 36, which is a lower outer surface of the raw - ie unpainted, uncovered - floor ceiling 28, and whose plane is parallel to the floor 28 level. The plate 36 serves primarily to heat exchange with the adjacent to the underside of the floor ceiling 28 space. The connecting web 35 connects the pipe receiving groove 7 of the Wärmeleitprofils 34 comprehensive area with the plate 36 of the Wärmeleitprofils 34. The connecting web 35 conducts heat to the plate 36, but also in the adjacent material of the concrete layer 32 and the ceiling support 29th

In the example shown in FIG. 1, the floor slab 28 has a lower cover layer 37, which evenly covers the ceiling slab 30 and ceiling support 29 downwards. The cover layer 37 is typically formed by adhering a mesh, filling and applying a plaster layer.

In the illustrated, particularly preferred construction of the ceiling support 29 is a composite support, which consists of at least two sub-profiles. The one part profile is the metallic heat conduction profile 34, the second part profile 38 is made of concrete.

The Wärmeleitprofil 34 by itself forms in cross-sectional view a trough, from the bottom center of the connecting web 35 projects up to well above the tub edges upwards and ends at its upper end in the tube receiving groove 7 comprehensive profile walls. For producing the composite support forming the ceiling support 29, said tank is simply filled with liquid concrete and allowed to harden in the tank so that it forms the partial profile 38. As outlined, the sub-profile 38 may also include reinforcing bars 39; These must be entered into the tub before pouring with concrete.

In order to achieve a good mechanical connection between the heat-conducting profile 34 and the concrete layer 32 or the partial profile 38 consisting of concrete, it is advisable to form the heat-conducting profile 34 perforated at least in regions and / or to form embossings, ie elevations or depressions, with respect to surrounding surface areas. wherein different embossed areas are to lie behind each other in the profile direction. Relative movement between the heat-conducting profile 34 and adjacent regions of the concrete layer or of the sub-profile 38 is thus positively locked in parallel to the profile direction.

FIG. 9 likewise shows a floor slab 40 according to the invention, which is formed as a brick suspension ceiling. The Wärmeleitprofil 41 is typically formed of a cementitiously bonded material. It has about the U-profile of the underlying base next to the two edge webs and two central profile webs are upstanding, which include between them the Rohraufnahmenut 42, in which the heat transfer fluid carrying pipe is located. Together with reinforcing bars 43 and a concrete filling 44, the heat-conducting profile 41 forms the ceiling support 45.

The Rohraufnahmenut 42 is in this case so deep that the tube 5 comes to lie so close to the lower surface of the floor slab 40, even if the thermal conductivity of the Wärmeleitprofils 41 is rather low (in extreme cases, even lower than that of in-situ concrete formed concrete layer 32), a good heat transfer between the tube 5 and the lower surface of the floor slab 40 comes to conditions.

To generalizations to the previously written is briefly noted:

The Wärmeleitprofile 6, 11, 18, 20, 24, 27, 34, 41 may be composed in itself of different material areas, so represent composite profiles of several sub-profiles or partial profile sections, for example, a partial profile of cementitiously bonded material and a metallic part profile or metallic partial profile sections. By a clever combination of materials can be compared to a self-homogeneous design possibly material and labor costs are reduced and still good surface and heat transfer properties can be achieved.

Those profile walls of a Wärmeleitprofiles 6, 1 1, 18, 20, 24, 27, 34, 41 which limit the Rohraufnahmut 7, 42 may also be missing at individual longitudinal regions of the Wärmeleitprofiles, for example, be milled away. Thus, an elegant way is created not only at the ends of the Wärmeleitprofile arches of the course of the heat transfer fluid-carrying tubes 5 form. It is thus gained flexibility with respect to the pipe courses.

In order to determine if necessary after the completion of the floor slab still quickly and safely the position of the heat transfer fluid pipes, in addition to the pipe - which is usually made of electrically non-conductive plastic - an electrical conductor, such as a wire o in the respective Rohraufnahmenuten a foil strip, to be entered. Thus, the position of the tubes by means of ordinary metal detector remains detectable.
