DESCRIPTION:
BRIEF SUMMARY
Solar modules are constructed on large-surface substrates which are made of e.g. glass; such solar modules comprise large-surface solar cells or a plurality of individual solar cells that are directly produced on the substrate and which are optionally integrally connected. These solar cells are secured to the substrate, connected together and optionally designed to be weatherproof by means of a laminated cover.
To erect the solar modules, they are usually secured on a support which may be a separate trestle, the facade or roof of a building or any other natural or artificial support.
Solar modules may comprise a frame with prefabricated means for securing the solar modules to the support. Solar modules which comprise bores within the substrate for the purpose of attachment are also known.
Frameless solar modules may be secured to a support by means of suitable clamps. Such clamps are known for example from DE A 41 30 214 (=GR91P1452DE).
Solar modules having a frame suitable for attachment are not cheap to produce. The attachment of solar modules by means of clamps is a complex technical procedure and does not guarantee that the solar module is securely held within the clamp. The solar module and clamp have to be handled separately from one another. Solar modules with securing holes are not easy to produce, inter alia because there is also a risk of damaging the solar module when drilling the holes.
U.S. Pat. No. 4,373,783 describes a heliostat or a solar cell module having a U-shaped frame securing device. The first horizontal wall portion of the U-shaped frame securing device is connected by means of an adhesive to a backplate which contains an aluminum foil, while the vertical wall portion is disposed along the edges of the solar cell module. The second horizontal wall portion of the U-shaped frame securing device comprises holes for securing the frame to a load-bearing structure.
Japanese application JP 04-323006 A describes, e.g., a production process for an external wall panel by means of which a building's heat and moisture can easily escape. A z-shaped frame is essentially integrated into the external panel. The process is based on securing an essentially z-shaped frame to a solid mold by means of a flange and a pin. A pin is introduced into an aperture provided within the z-shaped support. The mold is then filled up, causing that part of the z-shaped profile which is opposite the flange to be embedded. The flange and the mold are then removed so that the securing frame projects from the solid mold.
The present invention's problem is therefore to design a means that can be easily and reliably used to attach solar modules and in general other flat plate-shaped bodies to a support.
In accordance with the invention, this problem is solved by a invention is a Z-shaped profile made from a sheet of metal and which is glued, along one edge, to the body to be secured. Through-bores for receiving securing means are provided in the second (lower) horizontal wall portion of the Z-shaped profile.
The body's stability with respect to warping and consequently with respect to rupture is increased by means of the glued metal profile member which is usually produced by bending, drawing or casting, since the metal profile member exhibits considerable stability to warping in its longitudinal axis.
The securing device can be glued to the body as a standard feature when producing or machining this body, thus enabling automated production or gluing. This reduces the effort involved in securing the body, thus allowing attachment work to be performed more quickly and easily than is e.g. the case with clamps. As compared to a securing frame, the securing device according to the invention enjoys advantages in terms of materials an d hence costs.
The securing device can be glued to the body such that the first vertical wall portion of the Z-shaped profile makes contact with an edge of the body. In this way, the body edge is additionally protected from damage, e.g. an impact. This protection is ensured after gluing the securin
