Abstract
Description
Die Erfindung betrifft ein Montagebauelement für eine vereisungsfähige Bodenkonstruktion mit integrierter Kühlfläche. Es besteht aus einer oberen gekühlten Nutzfläche und einer unteren Deckplatte mit für das Zusammenfügen der Bauelemente geeigneten Randausbildungen und mit Anschlüssen für den Transport der Kühlmedien. Weiterhin beinhaltet die Lösung ein Verfahren zur Herstellung dieses Montagebauelements für eine vereisungsfähige Bodenkonstruktion mit integrierter Kühlfläche.
Derartige technische Lösungen werden bei der Errichtung von Wintersporteinrichtungen, beispielsweise für die Sportarten Eislauf, Skilauf und Rodeln, benötigt.The invention relates to a mounting component for an iceable floor construction with integrated cooling surface. It consists of an upper cooled working surface and a lower cover plate with suitable for the assembly of the components edge formations and with connections for the transport of the cooling media. Furthermore, the solution includes a method for producing this mounting component for an icable floor construction with integrated cooling surface.
Such technical solutions are needed in the construction of winter sports facilities, for example for the sports skating, skiing and tobogganing.
Für die Gestaltung von Boden-, Wand- und Deckenkonstruktionen werden Sandwichelemente eingesetzt, wie sie in der
Ebenfalls bekannt sind Wärmeübertrager mit kleinem hydraulischen Durchmesser der Strömungsquerschnitte, wie sie als Minichannels in der Zeitschrift KI Luft- und Kältetechnik, Heft 2/2004 auf den Seiten 47 - 53 beschrieben werden.
Nachteile der bekannten technischen Lösungen bestehen insbesondere darin, dass diese als Bodenkonstruktionen für hohe dynamische Belastungen, wie sie zum Beispiel auf einer Bobbahn auftreten, und durch die Wirkung des Eises an den Fugen zwischen den Montagebauelementen nicht geeignet sind.Also known are heat exchangers with a small hydraulic diameter of the flow cross sections, as they are described as Minichannels in the journal AI Air and Refrigeration,
Disadvantages of the known technical solutions are, in particular, that they are not suitable as floor constructions for high dynamic loads, as they occur, for example, on a bobsleigh track, and by the effect of the ice at the joints between the mounting components.
Bekannt sind auch Bodenkonstruktionen aus Beton mit integrierter Kühlfläche zur Bildung einer Eisschicht und für hohe mechanische Belastungen, wie sie beim Wintersport auftreten. Bei diesen Bodenkonstruktionen sind die Kühlrohrregister im Beton eingegossen. Die hohe Belastbarkeit der Bodenkonstruktionen wird durch ebenfalls in den Beton eingebrachte stabilisierende Bewehrung gesichert. Derartige Bodenkonstruktionselemente kommen mit Dicken von mindestens 200 mm als schwere Bauelemente vorwiegend in stationären Anlagen zum Einsatz. Die Kühlung erfolgt entweder durch den Transport von Kühlsole oder durch Verdampfung eines Kältemittels, vorzugsweise Ammoniak, im jeweiligen Kühlregister. Zur Vermeidung von Rissen in der Eisfläche infolge von Temperaturunterscheiden werden in bekannter Weise in den Fugen elektrische Heizstäbe eingebracht, um durch das Freischmelzen der Fugen Spannungen und damit Risse im Eis zu vermeiden. Nachteile dieser technischen Lösung sind der durch die schwere Bauweise nahezu ausgeschlossene Einsatz für mobile Sportanlagen. Weiterhin ist als Nachteil die ungenügende Wärmeleitung durch den Beton zur Eisfläche sowie die unzureichende Wärmedämmung durch den Beton zur unteren Auflagefläche zu bezeichnen. Infolge der benötigten hohen Kälteleistung und der geforderten Festigkeit werden große Rohrdurchmesser für die Kälteträgermittel und die dadurch begünstigte Eisbildung in den Fugen sowie der zusätzliche Energieaufwand für die Vermeidung von Eisrissen an den Fugen der Montagebauelemente als Nachteile erkannt.Also known are concrete floor constructions with integrated cooling surface for forming an ice layer and for high mechanical loads, such as occur in winter sports. In these floor constructions, the cooling tube registers are cast in the concrete. The high load-bearing capacity of the floor constructions is ensured by stabilizing reinforcement also inserted into the concrete. Such floor construction elements come with thicknesses of at least 200 mm as heavy components mainly used in stationary equipment. The cooling takes place either by the transport of brine or by evaporation of a refrigerant, preferably ammonia, in the respective cooling coil. To avoid cracks in the ice surface due to temperature differences electrical heating rods are introduced in a known manner in the joints in order to avoid tensions and thus cracks in the ice by the free melting of the joints. Disadvantages of this technical solution are the almost impossible due to the heavy construction use for mobile sports facilities. Furthermore, to denote the disadvantage of insufficient heat conduction through the concrete to the ice surface and the insufficient thermal insulation by the concrete to the lower bearing surface as a disadvantage. As a result of the required high cooling capacity and the required strength large pipe diameters for the refrigerant and thus favored ice formation in the joints and the additional energy required for the prevention of ice cracks at the joints of the mounting components are recognized as disadvantages.
Es ist deshalb Aufgabe der Erfindung eine technische Lösung zu schaffen, mit deren Hilfe die Mängel des bekannten Standes der Technik überwunden werden. Insbesondere geht es um die Entwicklung eines vorfertigungsfähigen plattenförmigen und selbsttragenden Montagebauelementes in leichter Bauweise für die Herstellung von vereisungsfähigen Boden- und Wandkonstruktionen. In diesen Montagebauelementen sollen die Kühlflächen in den oberen Nutzbereich integriert sein, wobei die obere Nutzfläche den aus dynamischen und durch Stöße entstehenden Belastungen der wintersportlichen Nutzung standhält. Mit Hilfe kleiner Rohrleitungsdurchmesser für das Kühlmedium und guter Wärmeleitung zur Eisschicht sowie mittels hoher Dämmwerte für die Wärmeleitung zur unteren Begrenzungsfläche soll in Verbindung mit besonderen Fugengestaltungslösungen eine Rissbildung im Eis vermieden werden.It is therefore an object of the invention to provide a technical solution by which the deficiencies of the prior art are overcome. In particular, it is about the development of a prefabricated plate-shaped and self-supporting assembly component in a lightweight design for the production of iceable floor and wall constructions. In these assembly elements, the cooling surfaces should be integrated into the upper working area, the upper usable area withstands the dynamic and shock loads resulting from winter sports use. With the help of small pipe diameters for the cooling medium and good heat conduction to the ice layer as well as high insulation values for the heat conduction to the lower boundary surface, cracks in the ice are to be avoided in connection with special joint design solutions.

In dieser oberen Nutzplatte sind ein oder mehrere Strömungskanäle mit als Kühl- oder Verdampferflächen dienenden Hohlräumen angeordnet.
Zwischen der oberen Nutzplatte und der unteren Deckplatte sind an den Rändern des Montagebauelementes Plattenrandprofile angeordnet.
Wenigstens Teile der äußeren Flächen der Plattenrandprofile des Montagebauelementes sind zur Lagefixierung einer dort anzuordnenden Fugendichtung konkav ausgebildet. In den konkav ausgebildeten Plattenrandprofilen sind Rillen angeordnet, die dem Ablauf eindringenden Wassers dienen.
Zwischen der oberen Nutzplatte und der unteren Deckplatte und den Plattenrandprofilen ist ein aushärtender lagefixierender und stabilisierender Isolierkern angeordnet.
Für das Zusammenfügen der Bauelemente in ausgewählten Randbereichen sind Verrieglungsvorrichtungen angeordnet, die der lösbaren kraftschlüssigen Schnellverbindung dienen.The object is achieved by the features of
Thereafter, there is a mounting component for an iceable floor construction of an upper cooled floor space and a lower cover with suitable for the assembly of the components edge formations and with connections for the supply and discharge of the cooling media. The upper cooled usable area consists of a top good heat conducting mechanically and dynamically highly loadable upper useful plate. In this upper utility plate one or more flow channels are arranged with serving as cooling or evaporator surfaces cavities.
Between the upper useful plate and the lower cover plate plate edge profiles are arranged at the edges of the mounting component.
At least parts of the outer surfaces of the plate edge profiles of the mounting component are concave for fixing the position of a joint seal to be arranged there. In the concave plate edge profiles grooves are arranged, which serve the drain penetrating water.
Between the upper useful plate and the lower cover plate and the plate edge profiles, a hardening position-fixing and stabilizing insulating core is arranged.
For the assembly of the components in selected edge areas Verrieglungsvorrichtungen are arranged, which serve the releasable non-positive quick connection.
Ein derartig gestaltetes Montagebauelement kann kostengünstig und in kurzer Zeit bei minimalen Ansprüchen an die Standortvorbereitung zur Herstellung von vereisungsfähigen Boden- und Wandflächen, von vereisungsfähigen Bahnen und von vereisungsfähigen Kanälen genutzt werden. Es ist ebenfalls möglich, solche Montagebauelemente in sogenannten Skitunneln einzusetzen. Ein besonderer Vorteil der erfindungsgemäßen Lösung besteht in der leichten Montier- und Demontierbarkeit und der hohen Stabilität der Elemente, die trotz geringer Eigenmassen wegen des Einsatzes der stabilisierenden Isolierkerne erreicht wird.Such a designed mounting component can be used inexpensively and in a short time with minimal demands on site preparation for the production of iceable floor and wall surfaces, icing-capable webs and icing channels. It is also possible to use such assembly components in so-called ski tunnels. A particular advantage of the solution according to the invention consists in the ease of assembly and disassembly and the high stability of the elements, which is achieved despite low intrinsic masses due to the use of stabilizing insulating cores.
Bevorzugt ist der aushärtende lagefixierende und stabilisierende Isolierkern ein im Druckschäumungsverfahren hergestellter Kunststoffschaum, vorzugsweise ein Polyurethanschaum.Preferably, the thermosetting layer-fixing and stabilizing insulating core is a plastic foam produced in the pressure foaming process, preferably a polyurethane foam.
Es ist auch möglich, die obere Nutzplatte aus zwei Teilplatten zusammen zu setzen, zwischen denen die erforderlichen Strömungskanäle eingearbeitet sind. Beide Teilplatten werden dabei miteinander kraftschlüssig unlösbar verlötet, verschweißt oder verklebt. Diese Ausführungsform erlaubt es, für die obere Nutzplatte verschiedene Materialien einzusetzen. Bevorzugt wird die obere Teilplatte aus einem Werkstoff mit guter Wärmeleitfähigkeit hergestellt, während die untere teilplatte der oberen Nutzplatte aus einem Werkstoff mit erhöhten Wärmedämmeigenschaften bestehen kann.It is also possible to put the upper useful plate of two partial plates together, between which the required flow channels are incorporated. Both partial plates are non-releasably soldered, welded or glued together. This embodiment makes it possible to use different materials for the upper useful plate. Preferably, the upper part plate is made of a material with good thermal conductivity, while the lower part of the upper plate upper plate may consist of a material with increased thermal insulation properties.
Die obere Nutzplatte wird vorzugsweise als extrudiertes Aluminiumflachprofil ausgebildet. Dadurch wird die Wärmeleitung zur vereisungsfähigen Fläche begünstigt, wobei gleichzeitig eine hohe mechanische Belastbarkeit gewährleistet wird.The upper useful plate is preferably formed as extruded aluminum flat profile. As a result, the heat conduction is promoted to icing surface, at the same time a high mechanical strength is ensured.
Die Strömungskanäle in der oberen Nutzplatte können mit hydraulischen Durchmessern ausgeführt sein, die denen üblicher Minichannels entsprechen.The flow channels in the upper plate can be designed with hydraulic diameters, which correspond to those of conventional Minichannels.
Zur Vermeidung von Verschleißerscheinungen kann die Nutzfläche der oberen Nutzplatte durch besondere Oberflächenbehandlungsmaßnahmen mit erhöhten Festigkeitseigenschaften ausgestattet werden, beispielsweise durch den Einsatz thermischer Verfahren oder durch Oberflächenbeschichtungsmaßnahmen.In order to avoid signs of wear, the useful surface of the upper useful plate can be equipped by special surface treatment measures with increased strength properties, for example by the use of thermal processes or surface coating measures.
Die Anschlussstutzen für die Zufuhr und für die Abfuhr des Kühlmediums sind mit der oberen Nutzplatte kraftschlüssig unlösbar verlötet, verschweißt oder verklebt und in beliebige Richtungen aus dem Montagebauelement herausführend angeordnet.
Weiterhin enthalten die Plattenrandprofile und die untere Deckplatte Ausschnitte, so dass die Anschlussstutzen für die Zu- und Abfuhr des Kühlmediums auch nach unten aus dem Montagebauelement herausführend angeordnet sein können.The connecting pieces for the supply and for the discharge of the cooling medium are positively non-detachably soldered, welded or glued to the upper support plate and arranged in any direction from the mounting component leading out.
Furthermore, the plate edge profiles and the lower cover plate contain cutouts, so that the connecting pieces for the supply and removal of the cooling medium can also be arranged leading out of the mounting component.
Die Fugendichtung wird vorzugsweise als hohle Randdichtung mit hoher elastischer Verformbarkeit ausgebildet, beispielsweise als Hohlprofil aus Gummi. Am äußeren Unfang der hohlen Randdichtung können Rillen zum Ablauf eindringenden Wassers angeordnet sein. Bei einem behinderten Wasserablauf kommt es im Falle der Vereisung nicht zu erhöhten Spannungen zwischen den Montagebauelementen, sondern zur Verformung der hohlen Randdichtung.The joint seal is preferably formed as a hollow edge seal with high elastic deformability, for example as a hollow profile made of rubber. At the outer periphery of the hollow edge seal grooves may be arranged to drain water entering. In case of obstruction of the water flow, there is no increased tension between the assembly components in the case of icing, but deformation of the hollow edge seal.
Das Herstellen des Montagebauelementes für vereisungsfähige Bodenkonstruktionen mit integrierter Kühlfläche erfolgt durch lagegenaues Anordnen von oberer Nutzplatte, unterer Abdeckplatte, den Randprofilen sowie die erforderlichen Sammler- und Anschlussstutzen für die Zufuhr des Kühlmediums, worauf anschließend diese Bauelemente dauerhaft fixiert werden. Dabei werden zunächst der Anschlussstutzen für die Zufuhr des Kühlmediums und der Anschlussstutzen für die Abfuhr des Kühlmediums mit der oberen Nutzplatte kraftschlüssig unlösbar verlötet, verschweißt oder verklebt. Anschließend werden die untere Deckplatte, die Plattenrandprofile und die die obere Nutzplatte enthaltende Baugruppe in eine die Bauteile fixierende Vorrichtung eingelegt. Danach werden die Bauteile des Montagebauelementes durch Einbringen eines unter Druck aushärtenden Schaumes, vorzugsweise Polyurethanschaum, dauerhaft lagefixiert und stabilisiert.
Der unter Druck aushärtende Schaum bildet dabei zugleich den erforderlichen Isolierkern, mit dessen Hilfe die in das Montagebauelement eingetragene Kälteenergie in erster Linie an die obere Nutzfläche herangeführt wird, ohne an die untere Deckplatte abgeleitet zu werden.The production of the mounting component for iceable floor constructions with integrated cooling surface is carried out by precise positioning of upper useful plate, lower cover plate, the edge profiles and the required collector and connecting pieces for the supply of cooling medium, whereupon these components are permanently fixed. Here, first, the connection piece for the supply of the cooling medium and the connection piece for the discharge of the cooling medium with the upper plate benefit non-releasably soldered, welded or glued. Subsequently, the lower cover plate, the plate edge profiles and the upper useful plate containing assembly are placed in a component fixing device. Thereafter, the components of the mounting component are permanently fixed in position and stabilized by introducing a pressure-curing foam, preferably polyurethane foam.
The pressure-curing foam at the same time forms the necessary insulating core, with the help of which registered in the mounting component cooling energy is primarily brought to the upper effective area, without being derived to the lower cover plate.
In einer besonderen Variante des Herstellungsverfahrens werden die Anschlussstutzen für die Zu- und Abfuhr des Kühlmediums beim Einlegen der die obere Nutzplatte enthaltenden Baugruppe durch die Plattenrandprofile und die untere Deckplatte mittels trichterförmiger Hilfsvorrichtungen eingeführt.In a particular variant of the manufacturing method, the connecting pieces for the supply and removal of the cooling medium when inserting the upper useful plate containing assembly by the plate edge profiles and the lower cover plate are introduced by means of funnel-shaped auxiliary devices.
Die Vorzüge der Erfindung bestehen zusammengefasst in der nun verfügbaren technischen Lösung für die Herstellung und Bereitstellung von leicht handhabbaren und gegenüber den bekannten technischen Lösungen bezüglich der Anforderungen an den Baugrund anspruchslosen Montagebauelementen für die Gestaltung von vereisungsfähigen Boden- und Wandflächen, Bahnen und/oder Kanälen. Hinzu kommt die hierdurch ermöglichte Anwendung von Montagehilfen in Form von Verriegelungsvorrichtungen, die der lösbaren kraftschlüssigen Schnellverbindung der Montagebauelemente dienen. Damit ist auch die vielfache Wiederverwendbarkeit ein markanter Vorteil der vorgeschlagenen Lösung. In dem für die obere Nutzfläche, den stabilisierenden Isolierkern und die untere Deckplatte Materialien mit unterschiedlichen Werkstoffeigenschaften zum Einsatz gebracht werden, lässt sich die einzutragende Kälteleistung mit hohem Wirkungsgrad auf die vereisungsfähige Nutzfläche übertragen und dabei zugleich auf ein technisches Minimum reduzieren.The advantages of the invention are summarized in the now available technical solution for the production and provision of easily manageable and compared to the known technical solutions with respect to the requirements of the ground undemanding assembly components for the design of iceable floor and wall surfaces, tracks and / or channels. In addition, this makes possible the use of mounting aids in the form of locking devices, which serve the releasable non-positive quick connection of the mounting components. Thus, the multiple reusability is a significant advantage of the proposed solution. In the materials used for the upper floor space, the stabilizing insulating core and the lower cover plate with different material properties are used, the input refrigeration capacity can be transferred to the iceable usable area with high efficiency and at the same time reduce to a technical minimum.
Das Reduzieren der einzusetzenden spezifischen Kälteleistung ist auch die Voraussetzung für minimierte Querschnitte der vorzusehenden Strömungskanäle für das Kühlmedium und für den minimierten Einsatz des zu handhabenden Kühlmediums.Reducing the specific cooling capacity to be used is also the prerequisite for minimized cross sections of the flow channels to be provided for the cooling medium and for the minimized use of the cooling medium to be handled.
