Definitions

• the invention relates to a guideway girder, in particular for a magnetic levitation railway, to form a guideway through a plurality of girders which follow one another in the direction of travel, with at least one upper girder section, in particular an upper chord and at least one support section arranged below the upper girder section, in particular a web.
• Such guideway girders have large areas. It is an object of the present invention to develop such a guideway girder in such a way that a simple yet highly efficient use of free areas on the guideway girder is realized.
• This object is achieved in the guideway girder of the type mentioned at the beginning by means of solar cells and / or solar collectors arranged in the region of the upper girder section and / or the at least one support section.
• the invention also proposes the use of solar cells and / or solar collectors for attachment in the region of a guideway girder which is arranged or can be arranged essentially above ground and has an upper girder section and at least one support section.
• the advantages of the invention lie in particular in the fact that solar cells and / or solar collectors used in this way permit a sensible use of the free support surfaces.
• the product produced by the solar cells graced electricity can be used, for example, to supply monitoring systems for the driveway or vehicles.
• measuring devices can be supplied with the current, for example temperature and humidity measuring devices.
• the current can alternatively or additionally be used for a system which controls the temperature of the carrier material. For example, if the carrier material is concrete, it can be heated in winter by means of embedded metal wires.
• the heat generated by the solar collectors can be used to heat water, also to generate electricity and to heat buildings, including parts of the guideway girders themselves. Cooling of buildings is also possible with the help of heat pumps.
• solar cell types can be used in the context of the invention, for example thin-film solar cells with a high power-to-weight ratio.
• flexible support materials for the solar cells e.g. made of plastic, also lends itself, since in this case the solar cells can be rolled up and large areas of the guideway girder can be covered in a simple manner.
• a further advantage of the use of the solar cells and / or solar collectors according to the invention in a guideway girder of the type mentioned at the outset is that, in particular, solar cells and / or solar collectors attached to the upper side protect the girder itself from direct sunlight and thereby an uneven relation to the girder cross section Warming and the associated deformation tion is avoided or reduced. Tighter tolerances can thus be maintained on the wearer.
• the route can also be designed as a bivalent route, on which, for example, both a magnetic levitation train and - with a much smaller track width - conventional trains can travel.
• the guideway girder - in particular when used for a magnetic levitation railway - has a hollow design in cross section.
• two opposite support sections or webs are preferably provided, which are connected to one another by means of the upper support section or upper belt.
• a lower support section or lower flange expediently closes the cavity at the bottom.
• the support sections can have inclined sections facing the sun, so that solar cells or solar collectors attached to them efficiently supply electricity or heat.
• the guideway girder In the case of, for example, relatively small curve radii, it is advisable for the guideway girder to have a full cross section, so that there is only one support section below the upper girder section. Solar cells and / or solar collectors are then arranged, for example, on one or both sides of the support section.
• the guideway girder is preferably mounted on one or more pillars embedded in the ground. This division allows a constructionally favorable processing of the carrier during manufacture as well as a relatively simple installation at the construction site.
• the space below the guideway girder can also be used.
• the solar cells and / or solar panels mounted on the guideway girder high above the earth are relatively protected against unauthorized access by third parties.
• the individual guideway supports are preferably arranged one behind the other in such a way that the distance between the successive support sections is small or negligible. In extreme cases, this results in a continuous support sequence in which the support sections form a kind of wall in the direction of travel, to which the solar cells and / or solar collectors can be attached. In this way, a large number of solar cells and / or solar panels can be accommodated on the guideway girder.
• the solar cells and / or solar collectors are preferably attached directly to free outer surfaces of the carrier.
• the solar cells and / or solar collectors accordingly cover these surfaces, which means that stronger winds in particular have hardly any contact surfaces for tearing the solar cells and / or solar collectors out of their attachment to the carrier.
• a guideway girder can have relatively large dimensions, it is advantageous for reasons of better manageability to arrange a plurality of smaller fields of solar cells and / or solar panels next to one another in the direction of travel of the guideway. This arrangement also makes it easier to replace damaged individual fields.
• the carrier is designed in such a way that the sunlit surfaces and / or masses of the carrier on the first and second belts are similar to one another, it is particularly advantageously achieved that a low temperature gradient will be present within the carrier.
• At least parts of the outside of the carrier have a heat absorbing or reflecting surface. In this way, for example, different solar irradiation of the individual parts of the carrier can be compensated for, so that the carrier is expanded evenly.
• the heat absorbing and / or reflecting surface can be applied to the carrier in the form of a paint. As a result, the different thermal properties of the carrier can be obtained very easily.
• a low temperature gradient of the carrier can also be obtained by this measure.
• the operating properties of the carrier can thus be adjusted to a wide variety of sun rays.
• means for heat compensation in particular for heat exchange, are provided between the first belt and the second belt or second belts. If the carrier is heated differently by, for example, solar radiation, it would deform undesirably due to the temperature gradient that arises as a result. The precisely aligned add-on parts would no longer have the required accuracy, so that the operation of a magnetic levitation train, for example, could not be guaranteed. Due to the arrangement of heat compensation or heat exchange means, it is now possible that, for example in the case of a more strongly warmed first belt, the heat generated in this way is fed to the second belt, whereby this is also heated and expands in a similar manner to the first belt.
• the heat can be directed specifically into the areas of the carrier which are likely to be heated less or which have a higher mass and would therefore require a longer time for heating.
• Lines with heat transfer fluid, in particular oil, have proven to be a means of heat compensation. The heat is transported from more heated areas of the carrier to less heated areas of the carrier via these lines.
• Cooling and / or heating elements are advantageous as active means for heat compensation. These cooling and / or heating elements, which can be operated, for example, via solar cells, can also keep the temperature gradient inside the carrier low when required and thus largely avoid deformation of the carrier.

• the solar cells 8 are not pulled up to the top chord 12, but close off at the top edge below the magnetic levitation train 100. Since the solar cells 8 have only a small diameter, it is of course also possible to also attach solar cells 8 to the web sections directly opposite the magnetic levitation railway 100.

• solar cells 20 are arranged on the web 4 '.
• the web 13 is more exposed to solar radiation than the web 14. It is to be expected that the side of the web 13 heats up more and would therefore lead to a deformation of the carrier 2 if no heat equalization took place , This heat compensation is effected with the help of the solar cells 20 and a line 21 connected to them.
• the line 21 conveys a heat transfer fluid from the sunlit side to the side of the support 2 lying in the shade.
• the web 14 and the lower flange 15 are also heated. This in turn leads to the fact that the thermal expansion on both sides of the carrier 2 is similar and the deformation of the carrier 2 is therefore within a tolerable range.

• the setting can be carried out in a particularly sensitive and precise manner by using temperature-dependent controlled presses which tighten the relevant tendons 19 to a greater or lesser extent to compensate for the deformation of the carrier 1 by one-sided heating.
