Definitions

  • the invention relates to a track segment for a sports track, in particular an ice rink, such as a toboggan run or bobsleigh track.
  • the WO 2013/062244 A1 describes a bobsled track that is constructed on site using shaped rebar and a concrete support framework.
  • the bobsleigh track contains embedded coolant lines to cool the track.
  • the EP 3243956 A1 describes a reinforced sports field surface with coolant lines, in particular for an ice rink.
  • the invention creates a track segment for a sports track with a curved track surface, which track segment is designed to be assembled at the front with other track segments to form the sports track.
  • Each track segment has a concrete shell with a first side facing the track surface and a second side facing away from the track surface.
  • a reinforcement and at least one coolant line extending over a large part of the surface of the track segment are arranged in the concrete shell.
  • the coolant line is preferably designed as a flexible hose and transports the thermal energy to the first side of the concrete shell, which forms the web surface, via a heating/cooling medium.
  • the reinforcement used can either consist of the usual structural steel or stainless steel, carbon and textile. Each of these types of reinforcement has its specific advantages and disadvantages, such as workability, price and service life.
  • the at least one coolant line is spaced at least toward the first side of the concrete shell to be below the surface of the concrete shell.
  • the coolant line is preferably as close as possible to the surface of the concrete shell, so that the cooling effect towards the track is optimized and, on the other hand, enough thickness of the material of the concrete shell remains towards the track to ensure stability during operation.
  • a track segment of this type can therefore be prefabricated extremely easily in the factory and assembled at the construction site to form a complete sports track, in particular an ice rink or bobsled track.
  • the assembly work at the installation site is significantly reduced, which also enables the track to be set up in places that are difficult to access.
  • the overall construction costs are significantly lower. Individual track courses can be put together as desired using appropriately prefabricated track segments for straight courses and curves.
  • the track segments only have to be connected at the front and anchored to the floor. Since the track segments are prefabricated in the factory under controlled conditions, the quality of the produced sports track much better overall than the on-site construction. This new type of artificial ice track construction therefore makes it possible to produce better quality, faster, more effectively and more cost-effectively. Setting up a production line in a precast plant and reusing formwork for each runway segment reduces costs.
  • the first side of the concrete shell can form the track surface.
  • the first side can also be coated with a protective layer, e.g. made of a polymer, in order to protect the concrete shell against the effects of the weather, for example.
  • concrete shell means the shaped, hardened, usually curving, concrete layer of the track segment that forms the structurally significant component of the track segment.
  • the concrete shell has nothing to do with formwork in the manufacturing sense.
  • inorganic building materials based on Portland cement are very well suited to transporting energy in the form of heat.
  • the track segment has a level standing section on its underside, so that it can be easily connected to a substructure or foundation produced on site.
  • the track segments can be fastened to the concrete substrate or foundation, for example with a connecting layer made of a polymer adhesive.
  • the standing section of the track segment alternatively/additionally has steel anchors for connection to a concrete substructure or foundation for the concrete shell, so that the track can be securely and quickly anchored to the subsoil.
  • the steel anchors then protrude downwards and have attachment means, such as bores, threads or the like, which can be connected to corresponding counter-anchors in the foundation.
  • a solid concrete foundation with a smooth surface is preferably made on site according to the slope of the sports track.
  • the above-mentioned steel anchors which can be anchored either in the track segment or in the foundation, are used as connecting elements to the track segments.
  • a connecting layer of high-performance mortar or epoxy resin can preferably be arranged between the track segments and the foundation.
  • the insulating layer represents part of a lost formwork for casting the concrete shell.
  • the insulating layer thus also functions as part of the casting mold when the track segment is produced in the factory. This reduces the amount of production waste and, on the other hand, ensures a close connection of the concrete of the concrete shell with the insulating layer, in particular when the insulating layer has roughness and/or porosity towards the concrete shell.
  • the at least one cooling line preferably extends in a meandering manner in the concrete shell, which ensures uniform and effective cooling of the web surface.
  • the track segment has connecting flanges on the face side for the coolant line.
  • the coolant lines of the adjacent track segments are preferably automatically connected to one another.
  • the risk of human error when connecting the coolant lines is minimized.
  • External connections of the coolant lines preferably protrude to the second side of the track segment, preferably in the area of the standing surface from the track segment and allow connection to corresponding cooling devices or coolant distribution devices.
  • the concrete of the concrete shell is shrinkage-compensated, which allows the production dimensions of the web segment to be chosen to be equal to the final dimensions, which in turn simplifies production and makes it less prone to errors.
  • a protective layer made of polymer, concrete or polymer concrete can preferably also be formed on the back of the insulating layer in order to protect the insulating layer from injuries during assembly and/or during operation.
  • the coolant line is also spaced toward the second side of the concrete shell to force cold delivery toward the first side.
  • the distance of the coolant line to the first side is much smaller than to the second side, so that the cooling effect is released near the surface of the web, where an ice layer is to be built up.
  • the spacing ratio is thus preferably between 1:2 and 1:10, in particular between 1:3 and 1:5. The cooling effect is thus optimized, especially since the second side is also insulated by the insulating layer.
  • the coolant line is preferably arranged at a small distance of 1 to 10 cm, in particular 1 to 5 cm, from the first side of the track segment forming the track surface—and at the same time the concrete shell.
  • the concrete shell preferably has a thickness of between 5 and 30 cm, preferably between 10 and 20 cm. It is thus rigid and strong enough for the intended use, e.g. by four-man bobs.
  • the strength of the concrete shell can be kept lower than with on-site assembly, since the manufacturing conditions of the track segments are defined in the company and the strength values of the concrete shell are better than with on-site construction, e.g. less air inclusions.
  • the thinner, prefabricated track segments can be transported by truck to the destination station of the sports track, while the comparatively low weight of the concrete shell means that they can be transported to the construction site along the course of the track, for example by helicopter.
  • the insulating layer has a thickness of between 10 and 20 cm. This strength results in effective thermal insulation, directing the cooling effect of the coolant lines to the first side of the web. In addition, the track segment does not become unwieldy in construction due to the insulating layer.
  • the track segment preferably has a length from end to end of 1 to 5 m, preferably between 2 and 3 m. Such a length represents a good compromise between transportability of the individual track segments (e.g. transport by helicopter), which favors short track segments and the Minimizing the effort involved in assembling the track segments, which favors long track segments.
  • the cooling lines are preferably fixed to the reinforcement, which has the advantage in terms of production technology that the cooling medium line does not have to be fixed from the outside, which in turn would result in defects in the concrete shell. In this way, a concrete segment with an optimized route for the coolant line can be easily produced without impairing the quality of the concrete shell.
  • the cooling lines are profiled, in particular corrugated, e.g. in the form of corrugated cooling hoses.
  • this leads to better "hooking" of the coolant line in the concrete of the concrete shell.
  • the heat transfer to the concrete shell is improved by the correspondingly enlarged surface of the coolant line.
  • the invention also relates to a sports track, in particular an ice rink, such as a toboggan run or a bobsled track, which comprises a number of track segments of the type described above that are placed end to end, the abutting ends of adjacent track segments being connected to one another.
  • the connection can be made by cementing over the front-side gap between two web segments, e.g. using a calcareous or organic binding agent or alternatively or additionally using a polymer-based sealant.
  • the track segments are thus connected to form a coherent, seamless sports track.
  • a polymer seal can preferably be arranged between the track segments, which allows a certain play and thus represents a buffer for seasonal thermal expansions of the track segments, which would add up in a one-piece track.
  • the coolant lines can preferably be connected to one another automatically by connecting flanges on the face side when connecting the track segments. In this case, however, the coolant lines of all adjacent track segments are connected to one another with a front connecting flange.
  • the coolant line of each track segment can therefore be led out at the rear and connected to a coolant distribution device, which connects the coolant lines of the individual track segments to one another, but which also allows the coolant line(s) of individual track segments to be shut off, which makes it possible to replace the corresponding web segment without having to drain the coolant of all web segments.
  • connection flanges would then be provided on the face side between the track segments of the same route section and the outermost track segments of the route section would be connected to a coolant distribution device.
  • flow of coolant through individual track segments or route sections can be adjusted via the coolant distribution devices.
  • coolant line instead of one coolant line, several coolant lines can be arranged in the track segment, which would have the advantage that the cooling capacity can be regulated simply by switching off coolant lines. In this way, for example, the cooling capacity can be adjusted to the outside temperature.
  • FIG. 1 shows a vertical section through a track segment 10 of a sports track 12, which consists of track segments 10 connected to one another at the front.
  • Each track segment 10 consists of a concrete shell 14 in which a reinforcement 16 and a coolant line 18 which is connected to the reinforcement 16 is arranged.
  • the coolant line 18 is arranged at a small distance of 1 to 10 cm, in particular 1 to 5 cm, from the first side 20 of the concrete shell 12 forming the web surface.
  • An insulating layer 22 is arranged on the rear side 24 of the concrete shell 14 and is already connected to the concrete shell 14 in a precast plant. Since the track segments 10 are completely prefabricated in the factory, they can be manufactured in a production-optimized manner under defined conditions. In this way, a low porosity of the concrete shell is achieved as well as a good connection between the concrete shell 14 and the insulating layer 22. This applies above all if the insulating layer 22 represents a lost formwork in the casting or manufacturing process of the concrete shell 14.
  • a protective layer made of a hard polymer, concrete or polymer concrete can optionally be arranged on the back of the insulating layer 22 in order to protect the insulating layer 22 during the assembly and use of the sports track.
  • the track segment rests on a site made foundation 26 of conventional structural concrete.
  • a connecting layer 30 made of a high-performance mortar or an epoxy resin is arranged between the foundation 26 and the level standing section 28 of the track segment 10, in which the track segment 10 is fixed to the concrete foundation 26, for example glued.
  • Connection layer 30 are also manufacturing tolerances, inaccuracies in the flatness between track segment 10 and concrete foundation 26 compensated.
  • concrete anchors 32 can be arranged in the standing section 28, which can be connected to counter-anchors 34 in the concrete foundation 26, e.g. via screw connections.
  • FIG. 2 shows the supervision according to II 1 with three web segments 10 connected to one another, which are connected to one another at their end face 36, the connection region of the end faces 36 of adjacent web segments facing one another being closable via a calcareous bonding agent and/or a polymer with sealing properties.
  • FIG. 3 shows the meandering course of the coolant line 18 in each concrete formwork 14, the concrete formwork being folded out here into the plane of the drawing.
  • the coolant lines 18 of adjacent web segments 10 can be connected to one another via connecting flanges 38, 40, which optionally automatically seal off tightly with one another when the adjacent web segments 10 are connected to one another.
  • the connecting flanges 38, 40 facing one another can have a diameter that is somewhat larger than that of the coolant lines 18, which enables the use of a sealing sleeve without impairing the free flow diameter for the coolant.
