Description

The present invention relates to a flat prefabricated element that can be used or mounted as an exterior, interior or apartment partition or as a ceiling element for the expansion or construction of prefabricated houses and halls, etc.

Flat prefabricated elements are prefabricated in a factory and thus delivered to a respective construction site shielded against the influences of weather and seasons. On the construction site, flat prefabricated elements are assembled directly as ready-to-install external, internal or apartment partitions or as roof or ceiling elements. In a very short time, an extension within an existing building, an extension or even the construction of an entire building in the form of a house or a hall on a prepared substructure can be realized using dry construction.

Flat prefabricated elements are either made of wood, residential concrete, brick or a hybrid or composite material made from the above or other materials, such as two corrugated sheet metal layers with plastic foam fixed in between, in solid or lightweight construction. Wood is the most widely used material for constructing a prefab element and is usually used as solid wood in the form of so-called cross-laminated timber, in technical jargon called Cross Laminated Timber, or CLT for short, or referred to as cross-layer wood or KLH . The wooden slats glued crosswise or connected with nails combine practical advantages such as fast, dry and precise construction with positive living characteristics and ecological unique selling points of a generally regional and binding large amounts of CO ₂ with comparatively low Environmental pollution of renewable raw materials with each other. They enable previously unknown constructive possibilities in timber construction with high energy efficiency and durability.

In a corresponding manner, flat prefabricated construction elements made of residential concrete, brick or a composite material, e.g. made of the materials mentioned, also meet all static, building physics and fire protection requirements and, due to their thickness or material strength or insulation that has already been applied, have high values for thermal insulation and also acoustic decoupling. In a production process, flat prefabricated elements, which are usually completely brought into a final contour, are delivered to a construction site complete and complete, including cut-outs for windows, doors and installations. Windows, doors, shutters, etc. can also be installed ready for use in the respective sections. A flat prefabricated element already has everything "in itself" and only has to be set up or built in and finally assembled at a destination and thus finally connected with a view to the prepared installations.

The object of the present invention is to provide a planar prefabricated element that can be used or installed as an exterior, interior or apartment partition or as a roof or ceiling element, with further improved properties, and that regardless of whether it is made of wood, Residential concrete, brick or a composite material.

This object is achieved according to the invention by the features of claim 1. Accordingly, a planar prefabricated element according to the invention has at least one planar recess on a surface oriented towards an interior in a final installation position, which recess is designed to accommodate a heating and/or cooling device.

A degree of standardization is rather low in the case of flat prefabricated elements, since individually designed prefabricated houses and tailor-made halls are generally desired on the market. Integrated digital planning on the basis of an image of a building to be erected in the computer today allows the so-called building data modeling or Building Information Modeling, BIM for short. BIM describes a working method for computer-aided, networked planning, construction and subsequent management of buildings and other structures. All relevant building data is digitally modeled, combined with each other and recorded in a uniform manner, so that a building can also be visualized geometrically as a virtual model. This approach optimizes the entire process chain within the planning and construction of buildings in a location and time-independent cooperation across all trades, which ensures more transparency, reliability and efficiency. At the same time, new scope for flexible design is created, especially in the construction of prefabricated houses, since the effects of plan changes can now be implemented and displayed or visualized in all plans without delay. For example, completely new positions for heating or cooling can be found on the basis of modeling of a room climate.

For reasons of better efficiency and aesthetics, but also to improve the use of space and a room climate, there has been an increasing shift away from conventional heating systems using radiators over the past few years. A modern heating system is progressively relocated into a wall or ceiling in order to invisibly perform heating and cooling tasks from there. While conventional radiators or heaters work with convection, i.e. use the air as a medium for heat transport, Wall heaters work with radiant heat. It is not the air that is heated, but the human body or objects in the room in a much more energetically efficient manner. In addition to significantly lower heating costs and freer room planning, there are other advantages of wall heating that, compared to radiators, heat that is perceived as more pleasant and comfortable is generated with significantly less dust raising.

Currently, when installing wall heating, corresponding recesses in walls and/or ceilings are usually only made by hand after installation of a prefabricated element by chiselling and/or milling. In addition to high levels of noise and dust, this method is time-consuming and consequently also expensive and the dimensions are rather inadequate and/or imprecise. A flat recess that is already provided at the factory on a surface in a prefabricated element that is oriented towards an interior space in a final installation position and is designed to accommodate a heating and/or cooling device increases the degree of prefabrication with high precision in the design increased significantly with optimum use of space. In this way, an assembly time for the installation and assembly of such a prefabricated element on site at a respective construction site with subsequent installation of surface heating or cooling and its connection is reduced even further. These specifications and optimizations can be implemented flexibly in a building data modeling with BIM networking from planning to production in the form of a flat prefabricated element according to the present invention.

On the basis of the respective requirements for a flat prefabricated element, the specialist must decide whether and how a flat recess or recess is to be provided during production for a planned heating and/or cooling device, with supply and discharge lines with connections etc. without further mention are always taken into account. Particularly in the case of concrete and brick construction, a recess can easily be realized during manufacture in the course of constructing the relevant planar prefabricated element as close as possible to the final contour, in order to reduce the scope of subsequent machining work steps. Irrespective of these considerations of a particular production practice, within the scope of the present invention, only a planar recess is spoken of without limitation.

Advantageous developments are the subject of the subclaims. Accordingly, the flat recess is designed to accommodate a heat-conducting profile, with the heat-conducting profile having a receptacle for the automatic fixing of an air-conditioning tube. In this case, a pipe guide bend is provided at one end of each parallel section of a continued, meandering course of the air-conditioning pipe adjoining a heat-conducting profile. In practice, several intervals consisting of a heat-conducting profile and a pipe guide bend are then repeated adjacent to one another until a predetermined planar recess is filled to achieve a planned heating and/or cooling capacity.

The heat-conducting profile preferably has an approximately omega-shaped receptacle for fixing an air-conditioning pipe, which will carry fluid in later use, on the surface oriented toward an interior space. Adjacent to the receptacle, the heat-conducting profile terminates in planar side surfaces which form a plane with one another or together.

From the DE 20 2010 011 801 U1 a wall and ceiling cladding with a heating and/or cooling device in the form of an air-conditioning pipe through which a correspondingly temperature-controlled fluid flows is known. The air-conditioning tube is automatically fixed in a spring-elastic heat-conducting profile, which in turn has several heat-conducting profiles arranged parallel to one another in a vertical is fastened to the heat-conducting profile running bracket, which is hung on end pieces between two parallel mounting rails. The support rails are attached to parallel support beams at constant intervals and form a substructure fixed to a wall or ceiling, as is generally known to the person skilled in the art as so-called stud frame from drywall construction. Cladding panels are attached to a plane formed by the support rails and the heat-conducting profiles, in particular in the form of plasterboard panels.

DE 20 2018 103 991 U1 discloses a modification of this structure by providing a mounting rail as a system rail with connecting elements integrated therein as one piece, which are designed as stamped and bent parts for latching in heat-conducting profiles provided with corresponding latching lugs. These mounting rails are suitable for direct mounting on a mounting surface, i.e. a wall or a ceiling. This mounting rail, as well as the heat-conducting profiles, are made of roll-formed sheet steel strips.

The disclosure of previously published Austrian utility model AT 17597 U1 and AT 17598 U1 the applicant is fully referred to.

An automatic fixation of the air-conditioning tube after the installation of the heat-conducting profile in the area of the approximately omega-shaped, spring-elastic clamping mount is always sufficient to ensure a defined and secure mounting of a air-conditioning tube. This means that an air-conditioning pipe is flexible once the other assembly work can be fixed in the heat-conducting profile itself with an individually freely selectable length of the air-conditioning pipe. For example, in a meandering form, any length of an air-conditioning pipe that can be selected can be laid over heat-conducting profile sections that are fixed parallel to one another to cover any conceivable surface shape.

The thermally conductive profiles known above all from the above-mentioned prior art can be used in an adapted manner within the scope of the present invention, with the carriers or brackets required according to the prior art for fixing the thermally conductive profiles being not required here, since according to one embodiment of the invention At least one latching element in the form of a latching arm or a latching lug is provided in an outer area of the heat-conducting profile, which is designed for at least punctiform latching engagement in the flat recess of the flat prefabricated element, in particular in a groove and/or an undercut in the recess. It is therefore not necessary to form a continuous latching, several point or line-shaped latchings have been recognized as sufficient fixation of the heat-conducting profiles in the recess.

An arrangement of two latching elements of the types mentioned is preferably provided symmetrically to the approximately omega-shaped receptacle on the heat-conducting profile. A use of similar latching elements is preferred. When selecting the type of locking elements, a respective form of manufacture of the heat-conducting profiles is taken into account, ie roll forming or extrusion.

In an alternative embodiment of the invention, at least one layer for adhesively fixing the heat-conducting profile to the flat prefabricated element is provided in the flat recess, which is provided as an alternative to a locking arm or a locking lug. Preferably in the flat recess two layers provided with two self-adhesive surfaces.

According to an essential development of the invention, each of the above-mentioned layers consists of a thermally insulating material in the form of a double-sided adhesive tape. In this way, thermal resistance between the heat-conducting profile and the flat prefabricated element is increased by appropriate material properties and also appropriate thicknesses of such a layer, so that heat transport between the heat-conducting profile with the air-conditioning tube fixed therein to the interior in question is improved, and this both in heating as well as cooling operation.

In an advantageous embodiment of the invention, the planar recess of the planar prefabricated element is defined by an outer frame which is fixed to the planar prefabricated element made of solid wood, residential concrete or clinker. A groove and/or an undercut is preferably formed in the recess, e.g. by profile strips, which form the outer frame and preferably other webs within the flat recess.

Preferably, the planar recess of the planar prefabricated element is closed with a drywall panel or a covering layer, for example made of plaster, which fills the planar recess and is designed to be flush with an adjacent outer surface. In this case, the plane formed by the planar side surfaces of the heat-conducting profile is covered in particular by an outer planking. This planking is preferably formed by a gypsum plaster board with a proportion of graphite to improve heat conduction to an interior space.

Alternatively, the flat recess is designed as permanent formwork in a flat prefabricated element made of concrete. The flat recess is preferably designed as a shaped body, e.g. made of silicone, that can be removed from the relevant prefabricated concrete element after the concrete has hardened and can therefore generally be reused. The solutions specified above for forming a planar recess in a planar prefabricated element further reduce the scope of post-processing work on the recess before installing a heating and/or cooling device in the recess.

The same reference symbols are always used below for the same elements across the various figures and exemplary embodiments. Without restricting the invention to this application, only a planar prefabricated element made of solid wood or cross-laminated timber is shown in the drawing as it is currently used most widely for prefabricated houses. The person skilled in the art is familiar with adaptations to lightweight constructions as well as to flat prefabricated elements made of residential concrete, bricks or other building materials.

figure 5 shows a perspective view of an intermediate step in a subsequent installation of a heating and / or cooling wall 1 in an outer wall 2 of a building not shown. To do this, the solid outer wall 2 had to be pried open over a minimum area A down to a predetermined depth t in order to create a defined recess 3 . An area B bordered by dashed lines indicates a flat thermal insulation additionally introduced into the area A of the recess 3, on which in mutually parallel pipe fastening systems 4, which are designed here as grid rails screwed in the wall 2, then a climate pipe 5 with a meandering course is inserted in a fixed manner. Then the recess 3 is filled with a layer of gypsum again in order to finally provide a smooth outer surface of the heating and/or cooling device 6 formed by the air-conditioning pipe 5 meandering in the pipe fastening systems 4 with wallpaper or wall paint. As a rule, this method can only be carried out largely by hand, which means that it is not only very dusty but also time-consuming and therefore expensive and the dimensions of the recess 3 are inaccurate. Nevertheless, this procedure is currently also used in prefabricated house construction in order to heat a room based on thermal radiation and thus very efficiently in terms of energy, while avoiding the even greater expense of installing underfloor heating. One The use of thermally insulating rigid foam panels towards an outer wall is also known, these carrying a fixed grid for laying the air-conditioning tube 5 in the form of polystyrene or wood fiber panels, for example, and making any additional tube fastening system 4 superfluous close. This, however, limits an individually optimized adaptability to an individual case, without significantly reducing the effort involved in installing a heating and/or cooling device 6 on site.

In order to reduce precisely this known effort when installing a heating and / or cooling device 6 and also to increase efficiency during construction with the aim of reducing costs, a prefabricated element 7 is described with reference to the figures described below, regardless of whether it made of wood or laminated wood, residential concrete, brick or a composite material has improved properties. figure 1 shows a top view of a first embodiment of a flat prefabricated element 7 made of cross laminated timber, in which a recess 3 has already been introduced at the factory. As will be explained below, grooves 8 are additionally provided in this recess 3, in each of which at least part of a heat-conducting profile 9 is arranged in a fixed manner, which in turn only accommodates the air-conditioning pipe 5 after the planar prefabricated element 7 has been installed. After the air-conditioning pipe 5 has been connected on site, the entire recess 3 is then usually only closed flush with an adjacent outer surface 10 . This can be done by filling it with wall plaster or by covering it with a drywall panel 11, each of which has a higher proportion of graphite for heat conduction.

A particular advantage of this flat prefabricated element 7 is that, according to the invention, a high degree of prefabrication has been deliberately shifted to production with the final contour so in a factory. Here, in the production of such flat prefabricated elements 7 in this exemplary embodiment with an advantageous connection to a BIM system, all customer-specific wishes are taken into account, so that each flat prefabricated element 7 delivered to a construction site for direct installation on site not only has prepared recesses and/or or installation shafts, e.g. for water, gas and electrical lines as well as empty pipes, but now also a perfectly prepared room for a highly efficient, space-saving and also invisible heating and/or cooling device 6.

As in the figure of figure 1 indicated, the heat-conducting profiles 9 can also have very different lengths, here by way of example lengths L ₁ , L ₂ , L ₃ , L ₄ . This means that not only openings for windows etc. can be provided within a heating and cooling device 6 without any problems, but also a slope running at an angle α in a flat prefabricated element 7, as can be seen through a roof or, in this exemplary embodiment, a staircase can result, are continuously provided in a defined manner with an air-conditioning tube 5. Complex surface shapes for a heating and/or cooling device 6 can therefore also be implemented very efficiently over a surface of a prefabricated element 7, as this exemplary embodiment of a heating and cooling wall 1 shows as an example.

When laying the air-conditioning pipe 5, minimum radii r and a minimum distance d within the meandering course of the air-conditioning pipe 5 must be observed. For this purpose, as an advantageous option, a pipe guide bend 9a is used at one end of each parallel route section or at a heat-conducting profile 9 directly. Such pipe guide bends 9a are implemented as cold-formed heat/cold baffles, so that in the course of the laying work within a continued meandering course of the air-conditioning pipe 5, a minimum radius r, as well as a minimum distance d to adjacent sections can be reliably maintained if two sections of the air-conditioning pipe 5 running parallel to one another are formed by two heat-conducting profiles 9 that are independent of one another, as provided in this exemplary embodiment. For alternatives, reference is made to the disclosure of the publications cited at the outset.

The course of individual heat-conducting profiles 9 and pipe guide bends 9a as sections arranged in a row is similar to that in figure 1 Insertion of the air conditioning tube 5 illustrated as a "slot car" route. A fixing of at least directly adjoining heat-conducting profiles 9 and pipe guide bends 9a to and with each other is not shown in this exemplary embodiment. However, such measures can easily be implemented in a manner recognizable to a person skilled in the art, for example by means of snap-in tabs or pin-hole pairings on adjacent components.

figure 2 shows a sectional view of the flat prefabricated element 7 according to FIG figure 1 in a level II-II. Here, an air-conditioning pipe 5 has already been inserted or pressed into the lined-up sections of heat-conducting profiles 9 and pipe guide bends 9a. At least the heat-conducting profiles 9 have a cross-section in which the air-conditioning tube 5 is accommodated and thereby automatically fixed, so that they have an approximately omega-shaped receptacle 12 for automatically clamping the air-conditioning tube 5 in it. A clamping enclosure of the air-conditioning pipe 5 is therefore not absolutely necessary for the pipe guide bends 9a. Due to the inherent rigidity of the climate tube 5, fixing it in the heat-conducting profiles 9 is basically sufficient. However, it is desirable for the air-conditioning pipe 5 to rest more than linearly on a respective pipe guide bend 9a for reasons of good heat transfer.

In any case, a receptacle 12 is arranged in the heat-conducting profiles 9 and possibly also in the pipe guide bends 9a in the installation position, oriented toward an interior space. The receptacle 12 runs out at least at the heat-conducting profiles 9 in planar side surfaces 13 which form a plane 14 . According to the present exemplary embodiment, a flat prefabricated element 7 is delivered to a construction site with heat-conducting profiles 9 and pipe guide bends 9a already fixed in the recess 3 . After the planar prefabricated element 7 has been inserted there and fixed mechanically, generally only the air-conditioning pipe 5 is inserted and fully connected on site.

A fixation of the heat-conducting profiles 9 in the area of the grooves 8 of the recess 3 of the flat prefabricated element 7 is shown in the exemplary embodiment figure 2 effected by double-sided adhesive tape 15. This double-sided adhesive tape has a layer 15 with two self-adhesive surfaces 16. The layer 15 is advantageously designed as thermal insulation with a thickness of 1 to 10 mm, preferably approx. 3 to approx . As a result, a flow of heat is oriented in the direction of the surface 10 and thus towards an interior space.

At the section of the planar prefabricated element 7 made up of layered plywood, the plane 14 is covered by a dry construction panel 11 to cover the recess 3 with a flush finish with the outer surface 10 . In this exemplary embodiment, the drywall panel 11 is fixed to the planar side surfaces 13 of the heat-conducting profiles 9 by gluing or screwing. Alternatively, this covering can also be realized with a smoothed or sprayed layer of plaster. In any case, a higher proportion of graphite is advantageously used in the cover to improve a Heat flow between the outer surface 10 and the heat-conducting profiles 9 and the climate tube 5 is provided.

In an exemplary embodiment that is not shown in more detail in the drawing, the use of a molded part and in particular a correspondingly shaped so-called lost formwork panel to form the planar recess 3 in a planar prefabricated element 7 subsequently produced from residential concrete with an in figure 2 illustrated and provided by numerous grooves etc. generated profiling. After completion of a concreting process, the lost formwork panel is an integral part of the planar prefabricated element 7. A cement-bonded wood fiber panel is preferably used as a molded part for this purpose. After installation of this flat prefabricated element 7 made of concrete composite material, the flat recess 3 formed by the lost formwork panel is planked with heat-conducting profiles 9 and sheets 9a, which are cut to length beforehand. That can, unlike in the figures 1 and 2 shown, also happen with a free choice of the grooves, so that areas within the flat recess 3 can also be used for other installations, eg for electricity, data lines, water or empty piping.

In a further alternative exemplary embodiment, for the factory prefabrication of a flat prefabricated element 7 with a suitably shaped recess 3, correspondingly shaped shaped bodies are placed in a formwork in a concrete plant. After the concrete has hardened, these shaped bodies are removed from the prefabricated concrete element 7, the shaped bodies, which can generally be reused, being made of silicone, for example. This leaves recesses in the finished flat prefabricated element 7, in which subsequently cut to length heat-conducting profiles 9 with thermal insulation etc. are fixed in the manufacturing plant. After a fixing installation at a destination then climate pipes 5 are inserted into the heat-conducting profiles 9 and room-side covers are attached, as already described above.

Special forms of fixing a heat-conducting profile 9 in a flat recess 3 are described below. The illustrations of Figures 3a to 4b show alternative versions of a fixation of a heat-conducting profile 9 in a recess 3 by locking elements 17. These locking elements 17 are in the embodiments of Figures 3a, 3b provided on an outer area of the heat-conducting profile 9 in the form of latching arms 17a arranged at different positions with spring-elastic hooks. These latching arms 17a are designed for an at least punctiform latching engagement in each case with an associated undercut 18 of the planar recess 3 . A layer 15 as thermal insulation is indicated between the locking arms 17a.

The illustrations of Figures 4a and 4b show further alternative embodiments of a fixation of a heat conducting profile 9 in a recess 3 by locking elements 17, which are designed here in the form of locking lugs 17b and are formed in the region of the omega-shaped recess 12 of the heat conducting profile 9. In the exemplary embodiments described above, an arrangement of two latching elements 17 of the same type is provided symmetrically to the approximately omega-shaped receptacle 12 on the heat-conducting profile 9 . The symmetrical structure of the locking elements 17 was shown in the illustrations Figures 3a, 3b, 4a, 4b used to be able to show two exemplary embodiments in two halves of an image.

In the embodiments of Figures 1 to 4b the recess 3 is realized in the planar prefabricated element 7 formed by cross-laminated timber in that a corresponding shaped outer frame 19 with the depth t is fixed on a thinner flat prefabricated element 7, so that milling work to form the recess 3 and to introduce grooves for the heat-conducting profiles 9 and, if necessary, their latching to undercuts 18 are omitted or only to a very small extent scope are to be carried out. The in figure 2 Areas bordered with a dotted line have been realized by further shaped or profile strips 20 with corresponding cross-sectional areas, which are fixed to the cross-laminated timber by gluing, gluing and/or stapling, nailing or screwing. A groove 8 is formed here by parallel profile strips 20 and not by milling or in any other way.

This means that, over a number of exemplary embodiments, a structure of a flat prefabricated element 7 that can be quickly and flexibly adapted to changeable technical specifications and/or wishes of builders with a heating and/or cooling device 6 that is almost completely prepared for direct installation on site and consists of a BIM-based planning has been described, which can be implemented very economically and can be installed on site with clear advantages in terms of time expenditure.
