The bearings of the pinion can be mounted on sleeves which are displaceable on the rod and z. B. can be fixed by means of grub screws. Thus, the chains are tensioned in a cost effective manner. If the chains wear, they can be re-tensioned. However, since the chains only have to perform a few rounds and since only maximum load occurs with certain rare wind loads, this will only rarely or possibly not be required. In addition, a comparatively large game is allowed anyway, since at a slightly lower mass of the counterweight than required, the elevation drive is biased as it were and since the lever arm is very long.

Furthermore, it may be provided that a side of the filling material facing away from the functional layer is flat in a finished state of the molded part and, in particular, rests flat against the carrier element.

The filling material is in particular a foam material or foamed material.

The filling material is in particular a hardening or already hardened material which stabilizes the functional position in its shape.

In particular, the filler stabilizes the functional layer in the form in which it rests on the shaping element.

The core may for example have a web structure.

The carrier element, in particular the carrier plate, is preferably placed on the filler material, while this is not fully cured.

In particular, this makes it possible to produce a large-area connection between the filler material and the sandwich element, for example a cohesive connection.

The filling material thus forms, in particular, an adhesive for bonding the functional layer to the sandwich element.

In particular, the filling material can compensate for and / or fill up inequalities and inaccuracies in the intermediate space between the functional position and the carrier element.

The support plate may for example comprise or be formed from a steel sheet, in particular galvanized steel sheet, for example with a thickness of approximately 0.5 mm.

The filling material may be, for example, an expanded or extruded plastic material, in particular polymer material.

Carrier-shaped sandwich elements are, in particular, stiffening ribs or stiffening webs, which are arranged and / or formed, for example, on a side of the filling material facing away from the solar element or the functional layer or a carrier plate arranged on the filling material.

It may be favorable if the carrier element comprises both a sandwich element extending over the entire extent of the solar element and / or the functional layer and additionally carrier-shaped sandwich elements. The sandwich element extending over the entire extent of the functional layer and / or of the solar element can then be made lighter and thus more material-saving by the use of additional carrier-shaped sandwich elements.

In particular, coated materials may be provided to prevent or reduce corrosion or other adverse weather conditions.

It can be provided that one or more cover layers and / or a sandwich core of one or more carrier-shaped sandwich elements have different material thicknesses, so that they can overlap one another in particular at a crossing point in the center of the carrier element and can be designed to be uninterrupted.

In particular, for the production of very large moldings, which in particular have surfaces of more than 5 square meters, for example at least about 10 square meters, the provision of the required shaping element can be very costly.

The present invention therefore also relates to a method for producing a forming element.

The shaping element preferably has a parabolic or spherical section shape.

Accordingly, the functional layer and / or the solar element preferably has a parabolic shape or spherical segment shape.

In particular, the above-described method of manufacturing a forming element can be used to provide very large forming elements for the manufacture of solar devices.

In particular, large heliostat data fields can thereby be manufactured cost-effectively.

In one embodiment of the invention can be provided that a support plate is provided, on which a filler, in particular a hard foam, such as foam boards, glued or otherwise attached.

The solar element 102 is preferably not directly on the sandwich element 116 established.

Rather, between the solar element 102 and the sandwich element 116 a gap 122 formed, which with a filler 124 is filled.

The filling material 124 is in particular a foam material, for example a plastic foam material.

By using the filling material 124 between the solar element 102 and the carrier element 114 can preferably on the one hand an optimal shape of the solar element 102 and on the other hand, a cost-effective design of the support element 112 be enabled.

In the 1 illustrated embodiment of the solar device 100 , in particular the carrier device 104 including the solar element arranged thereon 102 , is preferably produced as follows:
For shaping the solar element 102 becomes a very large shaping element 126 needed.

Such a shaping element 126 For example, it can be produced simply and inexpensively as follows:
First, a base material 128 For example, lean clay provided.

The base material is provided in particular as a pile or as a bed.

Approximately in the middle of the base material 128 becomes a central staff 130 anchored. This central staff 130 forms a rotary load 132 around which a turning bar 134 is rotatable.

The turning bar 134 is in particular movable in a substantially horizontal plane.

At a lower end of the turnstile 134 is preferably a peel-off template 136 or a negative mold slide arranged.

In particular, the peel-off template 136 or the negative mold slide 138 formed as a shaped metal sheet.

By rotation of the rotary bar 134 including the negative mold slide arranged thereon 138 or the peel-off template 136 around the central staff 130 becomes the base material 128 brought into a desired shape.

In particular, the base material is obtained 128 at its upper upper side with respect to the direction of gravity, a rotationally symmetrical shape whose cross-section is a negative form of the Abziehschablone 136 or the negative mold slide 138 equivalent.

In particular, this is the base material 128 provided with a parabolic shape or spherical section shape.

The central staff 130 , the turning bar 134 and the thereon Abziehschablone 136 or the negative mold slide arranged thereon 138 in particular form a puller 140 for removing the base material 128 ,

At an outer edge of the base material 128 For example, a border 142 be provided.

The border 142 is in particular formed annular and prevents unwanted removal of the base material 128 from one by means of the puller 140 detectable area.

After shaping the base material 128 by means of the puller 140 (please refer 2 ) becomes the base material 128 solidified.

This solidification can be achieved in particular by curing the base material 128 respectively.

Alternatively or additionally, it can be provided that the base material 128 covered with a (not shown) film and subjected to a negative pressure.

This also results in a solidification of the base material 128 , The solidified base material 128 in the given form finally forms the shaping element 126 ,

As 3 it can be seen, the shaping element 126 be used for shaping, in particular a functional position 144 on the shaping element 126 is hung up.

The functional position 144 forms in particular the solar element 102 ,

In a next step, the filler material 124 on the functional position 144 applied.

The filling material 124 is in particular a foam material, which on the functional position 144 is sprayed on and then cured.

In particular, before complete curing of the filling material 124 this is done with a carrier element 112 covered.

The filling material 124 is thus on the one hand by the functional position 144 and on the other hand from the carrier element 112 limited (see 5 ).

After complete curing of the filling material 124 is the solar element 102 by means of the filling material 124 reliable on the support element 112 established.

The unit of support element 112 , Filling material 124 and solar element 102 can then from the forming element 126 be removed.

The shaping element 126 then stands in particular for the production of further solar elements 102 together with associated carrier elements 112 to disposal.
