Abstract

A fastening system for a plate-shaped structural element on a pitched roof is provided. The plate-shaped structural element is bordered in a water-tight manner in a frame and fully replaces the roof covering, and the eaves-side and ridge-side cross beams of the frame which run transversely to the ridge-eaves direction have profiles which are matched to each other and engage in each other. The top side of the eaves-side cross beam has a mounting that surrounds the edge of the plate-shaped structural element, and the bottom side thereof has a support for fastening to the roof structure. The support includes a web that extends from the mounting to the support, a protrusion extending beneath the mounting and receives an extension that extends from the ridge-side cross beam thereof.

the support comprising a web that extends from a lower limb of the mounting and leads to the support, a protrusion that extends beneath the mounting from a side of the web so that a channel is defined by the mounting, the web, and the protrusion, and

the ridge-side cross beam having an extension that can be inserted into the channel of the eaves-side cross beam of the adjacent module,

wherein the ridge-side cross beam has an angled-off portion that rests on the support of the eaves-side cross beam of the adjacent module.

2. The fastening system as claimed in claim 1, wherein the support protrudes in an eaves direction.

3. The fastening system as claimed in claim 2, further comprising screw holes provided in the support.

4. The fastening system as claimed in claim 1, further comprising ventilation openings in the eaves-side cross beam and the ridge-side cross beam.

5. A fastening system for a plate-shaped structural element on a pitched roof having a roof covering, comprising:

a frame of profiled beams configured to border, in a water-tight manner, the plate-shaped structural element to form a module, the module being configured to fully replace the roof covering of the pitched roof,

the frame of profiled beams including an eaves-side cross beam and a ridge-side cross beam, each of the eaves-side cross beam and ridge-side cross beam having profiles that match each other and engage each other, the profiles forming a rain-proof joint such that an adjacent module partially overlaps in the longitudinal direction only in the region of the eaves-side and ridge-side cross beams,

the eaves-side cross beam having a top side provided with a mounting that surrounds an edge of the plate-shaped structural element in a U-shaped manner, and having a bottom side provided with a support for fastening to the roof structure,

the support comprising a web that extends from a lower limb of the mounting and leads to the support, a protrusion that extends beneath the mounting from a side of the web so that a channel is defined by the mounting, the web, and the protrusion, and

the ridge-side cross beam having an extension that can be inserted into the channel of the eaves-side cross beam of the adjacent module,

wherein the extension of the ridge-side cross beam has a bottom side that is provided with a water channel open in a ridge direction and into which the protrusion from the web of the eaves-side cross beam of the adjacent module protrudes.

6. The fastening system as claimed in claim 5, further comprising a bead spaced apart from the web and protruding into the channel in the direction of the protrusion, the bead being provided on a bottom side of the lower limb.

7. The fastening system as claimed in claim 6, further comprising a lip on a top side of the extension of the ridge-side cross beam, the lip of the module bearing against the bead of the adjacent module.

8. A fastening system for plate-shaped structural element on a pitched roof having a roof covering, comprising:

a first watertight module having an eaves-side cross beam with a bottom side and a top side, the bottom side including a support, the top side including a U-shaped mounting for surrounding an edge of a first plate-shaped structural element, the U-shaped mounting having a base, a lower limb, and an upper limb, the upper limb being adhesively joinable to the edge of the first plate-shaped structural element, the lower limb having a web extending from the U-shaped mounting to the support, the web having a downwardly curved protrusion defining a channel between the mounting, the web, and the protrusion, wherein the lower limb further includes a bottom side having a first bead protruding into the channel in the direction of the protrusion; and

a second watertight module having a ridge-side cross beam, the ridge-side cross beam having an upper girder and a base, the base including an angled-off portion resting on the support of the eaves-side cross beam of the first watertight module, the upper girder for covering and adhesively joining to an edge of a second plate-shaped structural element, the upper girder including an extension inserted into the channel of the eaves-side cross beam of the first watertight module so that the extension rests on the protrusion of the eaves-side cross beam of the first watertight module, the upper girder further including a water channel into which the protrusion from the web of the eaves-side cross beam of the first watertight module protrudes, wherein the extension includes a lip on a top side of the extension, the lip bearing against the first bead of the eaves-side cross beam of the first watertight module.

9. The fastening system as claimed in claim 8, wherein the water channel of the second watertight module includes a bottom side that is angled obliquely upward.

10. The fastening system as claimed in claim 8, wherein the first bead comprises an open loop pointing toward the web.
