ADJUSTABLE HOLDING ELEMENT FOR ROOFS WITH TRAPPY PROFILE

The present invention relates to a support member for fixing a bracket to a roof member having a multi-bead profile, the support member being attachable to the roof member, comprising a base member having a connection device for connecting the base member to the bracket and one to the base member arranged fastening device with two fastening elements for connection of the holding element with the roof element, wherein the fastening elements face each other and the fastening device in the attached to the Dacheiement state of the Haiteelementes surrounds one of the beads.

Roofs of houses, industrial plants or halls are often provided with roof elements that have a multi-corrugated profile. In this case, trapezoidal sheets are often used, wherein the beads are formed in a trapezoidal profile. Trapezoidal sheets with different trapezoidal shapes are available on the market. The trapezoidal shapes vary in the angle of the two side parts of the trapezium as well as in the width of the base side of the trapezoid.

It is often attempted to make sensible use of the unused roof surface of buildings by, for example, arranging solar modules on them and thus allowing a space-saving arrangement of the solar modules. The solar modules can be, for example, photovoltaic modules or thermal solar collectors. In the arrangement of such technical systems on roofs, which are formed of roof elements with a profile having several beads, there is the difficulty to reliably attach the technical equipment to the roof elements. One possibility is to screw the direct screwing of brackets of technical equipment on the upper, parallel to the roof surface extending surfaces of the roof element. In tra ezförmigen roof elements these upper surfaces form the base of the trapezoid. Furthermore Haiteeiemente are known, which are placed on the beads and embrace the beads. In this case, the holding elements usually have a base element with a Verbtndungsvorrichtung for connecting the holder of a technical system and a fastening device for fixing the holding element on the roof element. BasiseSement and fastening device are integrally formed. Known retaining elements in this case have bent from the base element fastening elements which bear laterally against the bead.

There are currently more than 20 different trapezoidal profiles available on the market. In practice, therefore, samples of the trapezoidal profiles to be used are shipped to the manufacturers of the holder elements and individual holding elements are produced for the profile to be used. The production of the holding elements is therefore relatively expensive due to small quantities and the individual adaptation. In addition, the known Haiteeiemente due to the one-piece design and the associated Abkantungsvorgänge consuming in the production.

In addition, the profiles of the Dacheiemente may have inaccuracies, so that the adapted for a bead Haiteeiemente may fit only insufficiently on the profile.

In particular, in the attachment of photovoltaic modules brackets are also used, which consist of several meters long rails and must be secured with several retaining elements. Due to the inaccuracies of the profiles of the roof elements, it may therefore happen that the Haiteeiemente can not be sufficiently aligned with each other, so that there may be problems with the connection of the holder to the holding elements,

It is therefore an object of the present invention to provide a holding element of the type mentioned, which is flexibly connectable to different roof elements. In this case, the retaining element can be constructed simply and inexpensively manufactured. The invention should also allow in a development that inaccuracies of the roof elements when using brackets can be compensated with a plurality of holding elements.

The invention is characterized in that at least one of the fastening elements is movably mounted on the base element, wherein the fastening device can be adapted to the bead by a movement of the fastening element. Due to the movable mounting of one of the fastening elements of the fastening device, an adaptation of the fastening device to different bead profiles is possible. In addition, inaccuracies of the beads of a profile can be compensated by the movable mounting of the fastener.
