Description

Description

The invention relates to a bridge construction with built-in solar cell elements - for generating electricity - and solar concentrators - for thermal use - of solar energy. In addition to the functionality of solar collectors, concentrators and solar cells, a sensible installation and integration of these solar units into bridge constructions is provided.

The invention is based on the task of creating a device that uses solar heat in temperature ranges of over 100 degrees to heat the roadway and, using solar cells, generates electricity for roadway lighting. The advantages of this device, which is mainly intended for use in bridge construction, are the full or partial utilization of the bridge superstructure

to generate solar energy. Valuable land areas are saved using this construction, which on the one hand are needed to set up solar generators and on the other hand make a complex power supply unnecessary when building bridges outside built-up areas.

In built-up areas, the solar panels are preferably fitted with sound-absorbing elements in accordance with DBGM No. 29501345. The costly, disfiguring retrofitting of some award-winning bridges would also be eliminated.

By tilting the main beam, the sky is reflected in the solar units, so that the viewer’s eye is presented with a delicate, slightly airy bridge structure. For cable-stayed bridges, the solar units are connected to one another in a force-locking manner on the stay cables.

This system would also be ideal for structures that provide rain and sun protection for stands. On the one hand for supplying hot water to the sanitary facilities and on the other hand for heating the lawn.

The illustrations show some examples of implementation, which show a range of design options without restricting the freedom of design.

Figure 10

shows the possibility of retrofitting (N) to existing bridge structures K. The suspended structure (N) is force-fitted to the main beam (1) and serves as a supporting structure for the installation of the solar units (3) with the associated solar equipment (G). Sound-absorbing elements (4) are arranged on the roadway side. Solar cells supply bridge and street lighting B via power storage, solar collectors heat the road surface H, for example via heat exchangers.
