Abstract

The method involves arranging a covering layer (9) in water permeable support layers (2, 8), and applying asphalt layers at a processing temperature for forming the support layers. Cooling pipes (3) are inserted into the asphalt layers, and the covering layer is applied on the support layers after hardening the asphalt layers. Coolant permanently flows through the cooling pipes at preset pressure and flow speed for producing defined heat transmission between the asphalt layers and the cooling pipes when the cooling pipes are inserted into the asphalt layers and made of plastic. An independent claim is also included for a sports flooring comprising a covering layer arranged in water permeable support layers.

Description

Die vorliegende Erfindung betrifft einen Spartboden, der mehrschicntig aufgebaut ist, und insbesondere ein Verfahren zur Herstellung eines solchen Sportbodens, dem eine definierte Absorberfähigkeit für eine bedatfsabhängige Erzeugung einer Eisschicht innewohnt.The present invention relates to a Spartboden, which is constructed mehrschicntig, and more particularly to a method for producing such a sports floor, which has a defined absorptive capacity for a subject-dependent generation of an ice sheet.

Im Freien liegende Sportflächen, wie beispieisweise Fußbalifelder, Tennisplätze, Hockeyplätze oder sonstige Ballsportplätze, können lediglich während den Sommermonaten bzw. bei entsprechenden Witterungsverhältnissen genutzt werden, Um zu verhindern, dass diese Flächen während der Winterzeit brach liegen, ist es mittlerweile vor allem in touristisch erschlossene Gebieten üblich, derartige Freiplätze mit einer Kunsteisbahn zu versehen. Hierdurch wird die Möglichkeit geschaffen, die freien Sportplätze auch im Winter für sportliche Betätigungen, wie Eiskunstlauf, Eishockey oder dergleichen zur Verfügung zu stellen.Outdoor sports surfaces, such as football fields, tennis courts, hockey courts or other ball sports fields, can only be used during the summer months or in the corresponding weather conditions. In order to prevent these areas being fallow during the winter, it has meanwhile become touristically developed Areas common to provide such outdoor courts with an artificial ice rink. This creates the opportunity to provide the free sports fields in the winter for sporting activities, such as figure skating, ice hockey or the like.

Um eine solche Kunsteisbahn auf entsprechenden Sportbefägen auszubilden, ist es bekannt, auf dem jeweiligen Sportbelag eine portable Absorberfläche mittels ausrollbaren Eismatten anzuordnen, die aus mehreren, in der Regel parallel verlaufenden flexiblen Kühlrohren bestehen. Eine entsprechende Eisfläche wird dann dadurch erzeugt, dass die Eismatten mit einem Kühlmittel durchströmt werden und gleichzeitig Wasser auf die Eismatten aufgesprüht wird, welches dann über einen bestimmten Zeitraum zu einem Eispanzer erstarrt.In order to form such an artificial ice rink on corresponding sports mounts, it is known to arrange on the respective sports surface a portable absorber surface by means of rollable ice mats, which consist of several, usually parallel flexible cooling tubes. A corresponding ice surface is then generated by flowing the ice mats with a coolant and at the same time water is sprayed onto the ice mats, which then solidifies over a certain period of time to an ice sheet.

Derartige Lösungen sind jedoch mit dem Nachteil behaftet, dass die Eismatten jeweils zu Beginn und zum Ende der Wintersaison auf- bzw. abgebaut und transportiert sowie während der Sommerzeit gelagert werden müssen, was die Betriebskosten derartiger künstlicher Eisflächen erheblich erhöht.Such solutions, however, have the disadvantage that the ice mats each at the beginning and end of the winter season up or dismantled and transported and stored during the summer time, which significantly increases the operating costs of such artificial ice.

Um einen solchen logistischen Aufwand gering zu halten, ist es auch bekannt, derartige Eismatten stationär auf den Jeweiligen Fralplätzen vorzusehen. In einer Ausführungsform werden derartige Elsmatten in einer im Randbereich des Sportplatzes angeordneten Versorgungskammer gelagert und bei Bedarf auf der Fläche des Sportplatzes ausgeroilt, um einen Eisbetrieb zu ermöglichen.In order to keep such a logistic effort low, it is also known to provide such ice mats stationary on the respective Fralplätzen. In one embodiment, such Elsmatten be stored in a arranged in the edge region of the sports field supply chamber and, if necessary, ausgeoilt on the surface of the sports field to allow ice operation.

Hierbei entfällt lediglich der Transportaufwand, nichtsdestotrotz ist eine Montage und Demontage der Absorberftäche notwendig. Darüber hinaus ist zusätzlicher Bauraum für die Versorgungskammer zur Aufnahme der Eismatten während der Sommermonate von Nöten.This only eliminates the transport effort, nevertheless, an assembly and disassembly of Absorberftäche is necessary. In addition, additional space for the supply chamber for receiving the ice mats during the summer months is needed.

in einer anderen Ausführungsform sind derartige Eismatten bereits stationär im Bereich des Sportbodens installiert. Die durch Kühlrohre in der Eismatte gebildeten Absorberbahnen sind hierzu auf einer in der Regel wasserdurchlässigen Asphalt-oder Betontragschicht flächig angeordnet, wobei die Zwischenräume zwischen den einzelnen Kühlrohren gegebenenfalls mit einem Quarzsand oder ähnlichem Material ausgebettet sind. Auf der durch die Absorberbahnen gebildeten Eismattentage wird dann abschließend ein Kunstrasen oder sonstiger, für die jeweilige Nutzung des Freiplatzes vorgesehener Sportbelag permanent aufgebracht und fixiert. Dem so gebildeten Sportboden wohnt also bereits die Fähigkeit zur Kühlabsorption inne.In another embodiment, such ice mats are already installed stationary in the area of the sports floor. For this purpose, the absorber webs formed by cooling tubes in the ice matting are arranged flat on a generally water-permeable asphalt or concrete wearing course, wherein the interspaces between the individual cooling tubes are optionally embretted with a quartz sand or similar material. Finally, an artificial turf or other sports covering provided for the respective use of the free space is permanently applied and fixed on the ice mat days formed by the absorber webs. The sports floor thus formed already has the capacity for cooling absorption.

Jedoch ist eine derartige Lösung unter anderem mit dem Nachteil behaftet, dass die Absorberschicht einer entsprechenden dynamischen Gewichtsbelastung ausgesetzt ist, was sich negativ auf die Haltbarkeit der Kühlrohre auswirkt. Des Weiteren führen unterschiedliche thermische Längenausdehnungen zwischen der Absorberschicht und der den Sportbetag bildenden Oberschicht, beispielsweise dem Kunstrasenbelag, auf der einen Seite sowie der darunter liegenden Asphalt- oder Betontragschicht auf der anderen Seite zu einem erhöhten Verschleiß der Kühlrohre, Es hat sich gezeigt, dass derartige, stationär vorgesehene und innerhalb des Sportbodens permanent vorliegende Absorberschichten eine Nutzungsdauer von 5 bis 10 Jahren nicht überschreiten.However, such a solution has, among other things, the disadvantage that the absorber layer is exposed to a corresponding dynamic weight load, which has a negative effect on the durability of the cooling tubes. Furthermore, different thermal length expansions between the absorber layer and the top layer forming the sports floor, for example the artificial turf covering, on one side as well as the underlying asphalt or concrete wearing layer on the other side lead to increased wear of the cooling tubes. It has been shown that such , stationary and provided within the sports floor permanently present absorber layers do not exceed a useful life of 5 to 10 years.

Aus der DE 44 43 403 C2 ist es bekannt, Kühlrohre eines Kühlsystems in einen Sportboden zu integrieren, der einen Tennenbelag bestehend aus Ziegelsand aufweist. Das aus Kühtrohren bestehende Kühlsystem wird hierbei entweder auf dem Tennenbelag aufgelegt oder in diesen integriert, so dass der Ziegelsand die Kühlrohre urngibt, Auch hier zeigt sich das Problem eines erhöhten Verschlelβes auf Grund der mechanischen Belastung der Kühlrohre.From the DE 44 43 403 C2 It is known to integrate cooling pipes of a cooling system in a sports floor, a Tennenbelag consisting of brick sand having. The existing of cooling pipes cooling system is hereby either placed on the Tennenbelag or integrated into it, so that the brick sand turns the cooling tubes, Again, there is the problem of increased Verschlelβes due to the mechanical stress of the cooling tubes.

Ausgehend von den vorhergehend geschilderten Nachteilen aus dem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, einen Sportbaden zur Verfügung zu stellen, der sich einerseits durch eine längere Haltbarkeit auszeichnet und andererseits einen einwandfreien Eisbetrieb einer Sommersportfläche realisiert. Darüber hinaus soll der Montage- und Wartungsaufwand eines solchen Sportbodens gering gehalten werden.Based on the previously described disadvantages of the prior art, it is an object of the present invention to provide a sports bathing, which is characterized on the one hand by a longer shelf life and on the other hand, a perfect ice operation of a summer sports surface realized. In addition, the installation and maintenance of such a sports floor should be kept low.

Gelöst wird diese Aufgabe mit einem Verfahren zur Herstellung eines Sportbodens mit einer Absorberfähigkeit für eine bedarfsabhängige Erzeugung einer Eisschicht nach Anspruch 1 sowie mit einem Sportboden jeweils nach Anspruch 9 und Anspruch 10.This object is achieved with a method for producing a sports floor with an absorber capability for demand-dependent production of an ice sheet according to claim 1 and with a sports floor according to each of claim 9 and claim 10.

Der Sportboden weist dabei zumindest eine wasserdurchlässige Tragschicht und eine auf dieser angeordnete oberste Belagschicht auf. Da es sich hierbei um Freiplätze handeln soll, ist es zwingend notwendig, dass die Tragschicht wasserdurchlässig ausgestaltet sein muss, damit Regenwasser abfließen kann. Damit einhergehend ist jedoch die Problematik verbunden, dass in die Tragschicht prinzipiell keine Kühlrohre aus Stahl eingelegt werden können, da diese mittelfristig rosten würden. Um zu verhindern, dass Kühlrohre rosten, könnten diese aus einem Edelstahlmaterial hergestellt werden, was jedoch erhebliche Kosten erzeugen würde.The sports floor has at least one water-permeable support layer and an uppermost covering layer arranged thereon. Since these are to be free spaces, it is imperative that the base layer must be permeable to water, so that rainwater can drain. Along with this, however, the problem is connected that in principle no cooling tubes made of steel can be inserted into the support layer, since they would rust in the medium term. To prevent cooling tubes from rusting, they could be made from a stainless steel material, but this would generate significant costs.

Ausgehend davon ist es daher eine Überlegung, auf welcher die Erfindung aufbaut, die Kühlrohre aus Kunststoff herzustellen. Dies birgt jedoch die Gefahr, dass beim Bau eines solchen Sportbodens der heiße Asphalt für die Tragschicht zu einer Aufweichung der Kunststofffohre mit der Gefahr von Wärmerissen oder sonstigen thermischen Verformungen führen würde, was grundsätzlich der Anordnung von aus Kunststoff hergestellten Kühlrohren innerhalb einer aus Asphalt oder ähnlichem Werkstoff bestehenden Tragschicht entgegen steht.Based on this, it is therefore a consideration on which the invention is based to produce the cooling pipes made of plastic. However, this entails the risk that in the construction of such a sports floor the hot asphalt for the base layer would lead to a softening of the plastic pipes with the risk of heat cracks or other thermal deformations, which basically the arrangement of cooling pipes made of plastic within an asphalt or the like Material existing support layer opposes.

Dieses Montagehindemis räumt das Verfahren gemäß der Erfindung vollständig aus, indem während des Einbringens der Kühlrohre in die heiße, in der Regel in einem Temperaturbereich von 120 - 160 °C vorliegende Asphaltschicht die Kühlrohre permanent von einer entsprechenden Kühtflüssigkeft durchströmt werden.This Montagehindemis completely clears the method according to the invention by the cooling tubes are permanently traversed by a corresponding Kühtflüssigkeft during the introduction of the cooling tubes in the hot, usually in a temperature range of 120 - 160 ° C present asphalt layer.

Die Kühltemperatur des Kühlmittels, welches Wasser sein kann, liegt hierzu vorzugsweise in einem Temperaturbereich von ca, 20 - 70 °C.The cooling temperature of the coolant, which may be water, for this purpose is preferably in a temperature range of ca, 20 - 70 ° C.

Um eine einwandfreie Kühlung der Kühlrohre während der Herstellung des mehrschichtigen Sportbodens zu gewährleisten, wodurch die Ausbildung von Wärmespannungen oder sonstigen thermischen Verformungen in den Kühlrohren verhindert wird, ist es gemäß der Erfindung vorgesehen, die Kühflüesigkeit mit einem definierten Druck und mit einer definierten Durchströmgeschwindigkeit durch die Kühlrohre zu schicken, so dass stets ein solcher Wärmeübergang, der die negativen thermischen Auswirkungen ausschließt, zwischen der Asphaltsehicht und den Kühlrohren vorherrscht. Der Druck und die Durchströmgeschwindigkeit ergeben sich beispielsweise aus dem Durchäussquerschnitt der zum Einsatz kommenden Kühlrohre, der Anzahl der Kühlrohre pro Fläche, dem Material der Kühlrohre, der Wandstärke der Kühlrohre sowie der entsprechenden Temperaturverhäftnisse beim Aufbringen des heißen und flüssigen Asphalts.In order to ensure proper cooling of the cooling tubes during the production of the multilayer sports floor, whereby the formation of thermal stresses or other thermal deformations in the cooling tubes is prevented, it is provided according to the invention, the Kühflüesigkeit with a defined pressure and with a defined flow rate through the To send cooling tubes, so that always such a heat transfer, which excludes the negative thermal effects prevails between the Asphaltschauicht and the cooling tubes. The pressure and the flow rate result, for example, from the Durchdurchussquerschnitt the cooling tubes used, the number of cooling tubes per surface, the material of the cooling tubes, the wall thickness of the cooling tubes and the corresponding Temperaturverhäftnisse when applying the hot and liquid asphalt.

Idealerweise kann hierbei gemäß der Erfindung noch eine Steuerung vorgesehen sein, die derart konzipiert ist, dass der Druck, die Durchströmgeschwindigkeit und die Temperatur der Kühlflüssigkeit über den gesamten Zeitraum des Aushärtens des Asphalts entsprechend auch der Abnahme der Temperatur des Asphalts über die Zeit variiert und angepasst wird, um stets den günstigsten, d.h. den für eine Unversehrtheit der Kühlrohre stabilisierendsten Wärmeübergang zu schaffen.Ideally, according to the invention, a control may be provided, which is designed such that the pressure, the flow rate and the temperature of the cooling liquid over the entire period of curing of the asphalt and the decrease in the temperature of the asphalt varies over time and adjusted accordingly is always the cheapest, ie to create the most stable for an integrity of the cooling tubes heat transfer.

Ist die Asphaltschicht zur Ausbildung der wasserdurchlässigen Tragschicht mit den dann integrierten Kühlrohren einmal ausgehärtet, kann abschließend die entsprechende Belagschicht für den jeweils vorgesehenen Sportbelag aufgebracht werden.Once the asphalt layer has hardened to form the water-permeable support layer with the then integrated cooling tubes, the corresponding lining layer can finally be applied to the respectively provided sports lining.

Für den Winterbelrieb können dann die Kühlrohre mit einer entsprechenden Kühfflüssigkeit, beispielsweise einem Frostschutz-/Wassergemisch durchströmt werden, das von einer Kältemaschine mit einer Temperatur von beispielsweise -7 bis -10°C stammt. Auf die Belagschicht, beispielsweise einem Kunstrasen, wird dann Wasser aufgesprüht, das dann zu Eis erstarrt. Die Kältemaschine, welche idealerweise mobil ist, wird elnfach bei Bedarf an die Kühlrohre in dem Sportboden über entsprechende Anschlusselemente angeschlossen.For the winter lining then the cooling tubes can be flowed through with a corresponding Küheflüssigkeit, such as an antifreeze / water mixture, which comes from a chiller with a temperature of for example -7 to -10 ° C. On the covering layer, such as an artificial turf, then water is sprayed, which then solidifies into ice. The chiller, which is ideally mobile, is simply connected as required to the cooling tubes in the sports floor via corresponding connecting elements.

Somit kann eine für den Sommerbetrieb vorgesehene Sportfläche, die gemäß der Ertlndung Kühlrohre integriert aufweist, rasch auf einen Kunsteisbetrieb umgestellt werden, ohne dass die Absorberschicht zusätzlich Installiert werden muss.Thus, a provided for summer operation sports surface, which integrates cooling pipes according to the Ertlndung be quickly converted to an artificial ice operation without the absorber layer must be additionally installed.

In einer bevorzugten Ausführungsform des Verfahrens gemäß der Ereindung werden in der aufgebrachten Asphaitschicht entsprechende Kanäle ausgeformt, die der Aufnahme der Kühlrohre dienen. Vorzugsweise werden die Kühlrohre hierbei in eine entsprechende Gussmasse eingebettet, die als zusätzliches Dichtungsmittel, Dämpfungsmittel und Mittel zum Ausgleich von unterschiedlichen Längendehnungs-Koefflzienten zwischen den unterschiedlichen angrenzenden Materialien dienen kann.In a preferred embodiment of the method according to the invention corresponding channels are formed in the applied Asphaitschicht, which serve to accommodate the cooling tubes. Preferably, the cooling tubes are thereby embedded in a corresponding casting compound, which can serve as additional sealing means, damping means and means for compensating for different longitudinal expansion coefflient between the different adjacent materials.

Der vorgesehene Sportbelag kann dann unmittelbar auf die Asphaltschicht und die in der Gussmasse eingebetteten Kühlrohre aufgelegt werden.The intended sports surface can then be placed directly on the asphalt layer and embedded in the casting compound cooling tubes.

Alternativ kann jedoch auch eine zweite Asphaltschicht auf die erste Asphaltschicht unter Einschluss der Kühlrohre aufgetragen werden.Alternatively, however, a second asphalt layer can also be applied to the first asphalt layer, including the cooling tubes.

Unterhalb der Tragschicht können noch, je nach Art des Sportbodens, diverse Stabilisierungsschichten, Schotterschichten und Bodenschichten vorliegen. Ebenso können zwischen der obersten Asphattschicht und der den Sportbelag ausbildenden Belagschicht Dämpfungsmatten oder ähnliches vorgesehen werden.Depending on the type of sports floor, various stabilization layers, gravel layers and soil layers may still be present below the base course. Likewise, damping mats or the like may be provided between the uppermost Asphattschicht and the covering layer forming the sports covering.

Der Kern des erfindungsgemäßen Verfahrens liegt demzufolge darin, dass während der gesamten Aushärtedäuer der Asphaltschichten, bei welcher diese mit einer für das Material der Kühlrohre kritischen erhöhten Temperatur vorliegen, die Kühlrohre, die für den späteren Einsatz für einen Eisbetrieb vorgesehen sind, mit einer Kühlflüsslgkeit durchströmt werden,The core of the method according to the invention therefore lies in the fact that during the entire curing dehydration of the asphalt layers, in which they are present with an elevated temperature which is critical for the material of the cooling tubes, the cooling tubes, which are intended for later use for an ice operation, are flowed through by a Kühlflüsslgkeit,

Der erfindungsgemäße Sportboden zeichnet sich demzufolge dadurch aus, dass in seiner Tragschicht Kühlrohre vorgesehen sind, die dem mehrschichtigen Sportboden eine Absorberfähigkeit für eine bedarfsabhängige Erzeugung einer Elsschicht auf dem Sportboden verleihen.The sports floor according to the invention is therefore characterized by the fact that cooling tubes are provided in its support layer, which give the multi-layer sports floor an absorptive capacity for a demand-dependent generation of a Elsschicht on the sports floor.

Gemäß der Erfindung sind die Kühlrohre hierbei als in die Tragschicht permanent integrierte Kunststoffrohre ausgebildet. Die Kunststoffrohre können hierbei idealerweise faserverstärkt sein. Als Querschnitt eignen sich Durchmesser von 15 bis 30 mm, wobei die Wandstärke zwischen 2 bis 3 mm liegen kann. Bevorzugtes Kunststoffmaterial soll hierbei Polyethylen sein.According to the invention, the cooling tubes are formed here as permanently integrated into the support layer plastic pipes. The plastic pipes can ideally be fiber-reinforced. As a cross section diameter of 15 to 30 mm, the wall thickness can be between 2 to 3 mm. Preferred plastic material is intended to be polyethylene.

Prinzipiell wäre es gemäß einem Aspekt der Erfindung auch ausreichend, dass die in der Tragschicht integrierten Kühlrohre den gleichen Längenausdehnungs-Koeffizienten aufweisen wie der Asphalt für die Tragschicht. Dies ermöglicht prinzipiell den Einsatz von Kühlrohren aus Stahl oder Edelstahl. Werden die Kühlrohre hierbei zusätzlich in einer entsprechenden Gussmasse eingebettet, lässt sich beim Einsatz von Stahl als Werkstoff auch ein Rosten verhindern.In principle, according to one aspect of the invention, it would also be sufficient for the cooling tubes integrated in the supporting layer to have the same coefficients of linear expansion as the asphalt for the base layer. This allows in principle the use of cooling tubes made of steel or stainless steel. If the cooling tubes are additionally embedded in a corresponding casting compound, rusting can also be prevented when steel is used as the material.

Es wird deutlich, dass der gemäß der Erfindung vorgeschlagene Sportboden und das zu seiner Herstellung vorgeschlagene Verfahren geeignet sind, bei Bedarf einen Kunsteisbetrieb ohne größeren Aufwand zu reallsieren. Da die Kühlrohre permanent in die Tragschicht integriert sind, und insbesondere für den Fall der Verwendung von Kunststoff als Material für die Kühlrohre, die dann in der Tragschicht, gegebenenfalls eingebettet in eine Gussmasse, permanent fixiert sind, ohne dass Druck- oder Witterungsbelastungen von außen einen Einfluss zeigen können, wird der Wartungsaufwand einer solchen funktional mehrfach nutzbaren Sportfläche gering gehalten. Der Sportboden zeichnet sich auch durch eine sehr hohe Lebensdauer aus; selbst bei einem Wechsel der obersten Belegschicht müssen die in der Tragschicht vorliegenden Kühlrohre nicht ausgetauscht werden.It becomes clear that the sports floor proposed according to the invention and the method proposed for its production are suitable for realizing an artificial ice operation if required without much effort. Since the cooling tubes are permanently integrated into the support layer, and in particular in the case of using plastic as a material for the cooling tubes, which are then permanently fixed in the base layer, optionally embedded in a casting material, without pressure or weather loads from the outside one Influence, the maintenance of such a functionally multiple usable sports surface is kept low. The sports floor is also characterized by a very long service life; even with a change of the top slip layer present in the support layer cooling tubes do not need to be replaced.

Weitere Vorteile und Merkmale ergeben sich aus den anhand der beiliegenden Zeichnungen dargestellten Ausführungsbeispielen.Further advantages and features will become apparent from the embodiments illustrated with reference to the accompanying drawings.

FIG. 1
schematically a cooling arrangement for a sports floor according to the invention;
FIG. 2
schematically a cross section through a sports floor, as it is in summer operation; and
FIG. 3
schematically a cross section through this floor in Kunsteisbetrieb.

Figur 1 zeigt schematisch ein Schaltbild für die Anordnung einer Kühlanordnung während der Herstellung des erfindungsgemäßen Sportbodens. FIG. 1 schematically shows a circuit diagram for the arrangement of a cooling arrangement during the manufacture of the sports floor according to the invention.

Während der Herstellung wird eine für den Sportboden vorgesehene Fläche 1 mit einer ersten Asphaltschicht 2 ausgekleidet. Während der Asphalt noch in seiner heißen Verarbeitungstemperatur vorliegt, werden idealerweise in einer parallelen Anordnung mehrere Kühlrohre 3 in die Asphaltschicht 2 eingebracht.During production, an area 1 provided for the sports floor is lined with a first asphalt layer 2. While the asphalt is still in its hot processing temperature, a plurality of cooling tubes 3 are ideally introduced into the asphalt layer 2 in a parallel arrangement.

Die Kühlrohre 3 slnd dabei über entsprechende, hier nicht näher dargestellte Anschlüsse mit einem Kühlsystem verbunden, welches aus einem Kälteaggregat 4 besteht, beispielsweise einem Kühlturm oder einem Luftkühler, und einer Pumpe 5, die über entsprechende Leitungen 6 eine Kühlflüssigkeit in dem System zirkulieren lässt.The cooling tubes 3 slnd connected via corresponding, not shown here connections with a cooling system consisting of a refrigeration unit 4, for example, a cooling tower or an air cooler, and a pump 5, which circulates via corresponding lines 6, a cooling liquid in the system.

Das Kälteaggregat 4 und die Pumpe 5 sind dabei mobil, beispielsweise auf einem LKW, angeordnet.The refrigeration unit 4 and the pump 5 are mobile, for example, on a truck arranged.

Während des Aushärtens der Asphaltschicht 2 zirkuliert die Kühlflüssigkeit durch die Kühlrohre 3 mit einer solchen Temperatur, dass sich der heiße Asphalt der Asphaltschicht 2 nicht negativ auf die Materialeigenschaften der Kühlrohre 3 auswirkt.During the curing of the asphalt layer 2, the cooling liquid circulates through the cooling tubes 3 at a temperature such that the hot asphalt of the Asphalt layer 2 does not adversely affect the material properties of the cooling tubes 3.

Hierdurch wird es möglich, Insbesondere aus Kunststoff hergestellte Kühlrohre 3 in einer solchen Asphaltschicht 2 enzuordnen, die dann zu einem späteren Zeitpunkt zur Erzeugung einer Elsschicht genutzt werden können.This makes it possible to enzuordnen especially made of plastic cooling tubes 3 in such an asphalt layer 2, which can then be used at a later time to produce a Elsschicht.

Für diesen Einsetzweck werden die Kühlrohre 3 dann ebenfalls an ein Kälteagaregat mit einer Pumpe und entsprechenden Leitungen angeschlossen, wobei jedoch dann in dem Kühlsystem ein entsprechendes Kühlmittel mit einer Temperatur unterhalb von 0°C zirkuliert.For this Einsetzweck the cooling tubes 3 are then also connected to a Kälteagaregat with a pump and corresponding lines, but then circulates in the cooling system, a corresponding coolant at a temperature below 0 ° C.

Figur 2 zeigt im Querschnitt einen erfindungsgemäßen Sportboden in mehreren Schichten. FIG. 2 shows in cross section a sports floor according to the invention in several layers.

In der darin gezeigten Ausführungsform sind die Kühlrohre 3 in einer ersten Asphaltschicht 2 in Kanälen 7 aufgenommen. Theoretisch könnten die Kühlrohre auch in die heiße und daher noch verformbare Masse des Asphalts eingedrückt werden, Jedoch ist es zur besseren Stabflisierung und Führung der Kühlrohre 3 in Parallelanordnung vorteilhafter, entsprechende Kanäle 7 in der ersten Asphaltschicht 2 auszubilden.In the embodiment shown therein, the cooling tubes 3 are received in channels 7 in a first asphalt layer 2. Theoretically, the cooling tubes could also be pressed into the hot and therefore still deformable mass of the asphalt, However, it is more advantageous for better Stabflisierung and leadership of the cooling tubes 3 in parallel arrangement to form corresponding channels 7 in the first asphalt layer 2.

Derartige Kanäle 7 schaffen auch die Möglichkeit, dass die Kühlrohre 3 noch mit einer entsprechenden, hier nicht dargestellten, Gussmasse umhüllt werden, die die thermischen und Dämpfungseigenschaften der Kühlrohre 3 verbessern kann.Such channels 7 also create the possibility that the cooling tubes 3 are still enveloped with a corresponding, not shown here, casting compound, which can improve the thermal and damping properties of the cooling tubes 3.

Auf die erste Asphaltschicht 2 mit den darin integrierten Kühlrohre 3 wird eine zweite Asphaltschicht 8 aufgetragen.A second asphalt layer 8 is applied to the first asphalt layer 2 with the cooling tubes 3 integrated therein.

Beim Aushärten der beiden Asphaftschichten 2 und 8 werden die Kühlrohre 3 permanent von der Kühlflüssigkeit durchströmt, wobei sich hierfür Wasser in einem Temperaturbereich zwischen 20 und 70°C eignet.When curing the two Asphaftschichten 2 and 8, the cooling tubes 3 are constantly flowed through by the cooling liquid, with this water in a temperature range between 20 and 70 ° C is suitable.

1st dann auch die oberste, zweite Asphaltschicht 8 vollständig ausgehärtet, lässt sich die für den jeweiligen Einsatzzweck vorgesehene Belagschicht 9, beispielsweise ein Kunstrasenbelag für Fußball oder ein Teppichbelag für Tennis, gegebenenfalls unter Zwischenlage von weiteren Schichten, auftragen und entsprechend befestigen, bspw. durch Kleben.Is then the top, second asphalt layer 8 completely cured, can be provided for the particular purpose coating layer 9, for example, an artificial turf for football or a carpet for tennis, optionally with the interposition of other layers, apply and attach accordingly, eg. By gluing ,

Figur 3 zeigt exempfarisch den erfindungsgemäßen Sportboden im Kunsteisbetrieb. FIG. 3 shows exempfarisch the sports floor according to the invention in Kunsteisbetrieb.

Durch die Kohlrohre 3 kann dann ein entsprechendes Kühlmittel geleitet werden, während auf die obere Belagschicht 9 Wasser aufgesprüht wird, welches dann entsprechend aneist und eine Kunsteisschicht 10 ausbildet, die dann für Wintersportarten genutzt werden kann.Through the cabbage tubes 3, a corresponding coolant can then be passed while sprayed onto the upper lining layer 9 water, which then aneist accordingly and forms a Kunsteisschicht 10, which can then be used for winter sports.
