The invention relates to a fastening system for large-area roof coverings or wall claddings.

The object is to create a fastening system which is structurally simple, consists of few parts, is fast to install and is suitable for high negative wind loads.

Fastening is achieved within two upwardly projecting longitudinal ribs 2, which are formed by upwardly projecting sheet metal flanks 11. These sheet metal flanks 11 are bent up and provided with projections 13. According to the invention, T-shaped base bars 3 are disposed and fastened within the upwardly projecting longitudinal ribs 2, either continuously or only in some places. The horizontal wide limb of the T-shaped base bars 3, designated as foot limb 5, can be disposed upwardly or downwardly. The T-shaped base bar 3 has recesses 6 formed left and right in the vertical limb of the T-shaped base bar 3 and reaching into the foot limbs 5. Specially formed projections 13 of the sheet metal flanks 11 of the roof elements, sheet metal plates or sheet metal strips 1 engage in these recesses 6. These preformed projections 13 result in a form-fitting joint in conjunction with press plates 9 that can be disposed at or on the central limb 4. The press plates 9 are appropriately fastened with the base bar head 7 in a form-fitting manner or, for example, with screws. The press plates 9 are formed such that the press plates 9 span over the projections 13 of the sheet metal flanks 11 of the roof elements, sheet metal plates or sheet metal strips 1 positioned side by side. This creates a durable form-fitting joint by means of the T-shaped base bar 3 (or base element), central limb 4 and press plate 9. At the upper ends of the upwardly projecting lateral sheet metal flanks 11, the whole longitudinal rib is closed towards the top with a cover strip 12.

A structural panel system formed from a substrate (such as cement board or paper) and structural metal studs (such as lightweight galvanized steel members), where the metal studs are embedded within an insulating core that is formed onto the substrate, where the metal studs are gapped from the inner surface of the substrate to prevent thermal energy from transferring from the substrate to the metal stud or vice versa. In addition, parallel assembly slots may be formed in the gap at the top and bottom ends of each panel assembly to provide connective access to the top and bottom ends of the metal studs for structural connection to the foundation at the bottom or other overhead structure at the top via connective components. The connective components include a bottom U-channel member and a top U-channel member that are configured to fit into the parallel assembly slots.

A roof pan with raised ridges along lateral edges, where the raised ridges of one pan cooperate raised ridges of another pan to prevent water movement. A formed edge that is offset from the roof surface when the pan is installed on the roof allows a flashing to slide under the formed edge when the roof pan is installed on the roof surface.

A mounting device (10) is disclosed having a one-piece body (11). A slot (20) extends into this body (11), and is defined by a slot base (22) and a pair of spaced slot sidewalls (24a, 24b) that each extend from the slot base (22). The slot sidewalls (24a, 24b) are disposed in non-parallel relation to each other.

Building integrated photovoltaic (BIPV) systems provide for solar panel arrays that can be aesthetically pleasing and appear seamless to an observer. BIPV systems can be incorporated as part of roof surfaces as built into the structure of the roof, flush or forming a substantively uniform plane with roof panels or other panels mimicking a solar panel appearance. Pans supporting BIPV solar panels can be coupled by standing seams, in both lateral and longitudinal directions, to other photovoltaic-supporting pans or pans supporting non-photovoltaic structures, having both functional and aesthetic advantages. In some configurations, the appearance of BIPV systems can be particularly aesthetically pleasing and generally seamless to an observer.
