Description

The The present invention relates to a retaining element, in particular for Placing on a roof skin and / or holding at least one Energy generation module, preferably a photovoltaic module, a solar collector or the like, and an arrangement comprising a variety of energy harvesting modules that are used in a variety of Holding elements are held.

The hitherto conventional holding elements, often designed as photovoltaic module holders, prevent lifting of the photovoltaic modules by wind suction either by frictional connection with the roof structure or by heavy mounts that with sufficient weight held the suction. The DIN 1055 Part 4 prescribes a suction load by wind.

The bolted retaining elements, usually made of aluminum or steel profiles are manufactured at defined points with the roof construction over the roof cladding bolted non-positively.

The Heavy holding elements are molded parts made of concrete or other materials or they are tubs or profiles made with sand, gravel, water or concrete slabs filled and weighted.

The screwed holding elements have the disadvantage that they are the sensitive Penetrate roof skin and thus create weak points in the roof skin. The thermal insulation must be for the support points be interrupted, so that additional thermal bridges arise with the risk of condensation. The penetration points need regular maintenance. The Support points must be especially in wooden and steel roof structures be aligned exactly to the support grid of the roof and are thus restricted in their possible arrangement.

The Heavy holding elements bring additional load on the Roof and thereby require a statically more complex roof construction. The laying is complicated by the distribution of large ones Masses and increases the risk of a roof skin damage through the assembly process. In case of a leak search need these masses are cleared with effort. The location of heavy holding elements is especially in wooden and steel roof structures limited in their possible arrangement, since to take account of the carrier layers.

The holding elements are preferably positively connected to the energy harvesting modules and thereby form a coherent structure.

The Holding means may, for. As steel, plastic or other materials be prepared.

The Holding means, as already mentioned, not just one Lift-off protection available, but also a slipping or positional securing, which is the entire arrangement of holding elements and energy recovery modules slipping (in essence horizontal direction). That in turn allows a placement of the arrangement not only on flat, but also on slightly inclined wings, such. B. slightly inclined Roofs.

The Aerodynamics of the whole arrangement is extreme advantageous because the energy harvesting modules with at least 1 cm Distance in the direction of passage to the adjacent power generation module be moved. This arrangement reduces the resulting wind suction clear. Furthermore, prevent the closed side walls submerging the energy harvesting modules. The front ends an energy recovery module series but not be formed closed.
