Mounting system for mounting a solar module on a roof of a building

The invention relates to a mounting system for mounting a solar module on a 5 roof of a building, wherein the roof has at least two trusses, preferably parallel to each other, at least two preferably parallel aligned purlins spaced apart from each other on top of the trusses, as well as a roof covering on the top lying on the purlins.

Solar modules are attached to the purins by means of known mounting : systems. It is disadvantageous in this respect that purlins — in particular in the case of hall roofs, the roof covering of which is usually made of corrugated metal sheet, or another relatively light material — are not designed to be sufficiently strong. In addition, high wind loads can act on solar modules and must also be absorbed by the purlins in addition to the weight loads.

The object of the invention is to avoid the aforementioned disadvantages and to specify a mounting system by means of which solar modules are securely fastened even in buildings with large roof surfaces and also in the case of high wind loads.

This object is achieved in that the mounting system for mounting at least one solar module above the roof covering has at least one mounting element which is fixable to the truss and that the mounting system further comprises a . oC fastening element whose one end interacts with the mounting element and is located opposite the other one, wherein the fastening element is guided fo @

= through a recess in the roof covering so that at least one solar module can at = least be attached to the truss. In the assembly system according to the " invention, the mounting element is arranged under the roof. At least one " mounting element can be fixed laterally to the truss, for example by means of a = bolted connection. Of course, other ways of fixing the mounting element to the o truss are also possible. For interaction with the mounting element, one end of = the fastening element can, for example, have a bolted connection. Through the o mounting system according to the invention, the weight force of the solar - modules and also-occurring high wind loads are introduced directly into the truss, which is regularly significantly larger and thus dimensioned stronger in this respect than the purlins arranged thereon.

At least one mounting element and at least one fastening element can be designed in one piece.

At least one mounting element and at least one fastening element can be designed in two parts. In such a configuration, the mounting element can first be fastened to the truss, for example. The roof covering can then be applied.

Alternatively, it is also possible for the roof covering to be initially placed on the purlins and fixed thereon, and then the mounting elements mounted on the trusses. In a next working step, the solar module is fastened to the mounting element and thus to the truss by means of the fastening element.

At least one fastening element can be designed as a hanger bolt. There are different types of hanger bolts. Usually, a hanger bolt has a thread, preferably a self-cutting one at one end, so that this end of the hanger bolt can, for example, be screwed into wood, in sheet metal or the like. A further, usually metric, thread is provided at the other end of the hanger bolt. An object can be fastened at a distance from a further component, in the present case the truss, by means of a hanger bolt.

The height of at least one mounting element can correspond approximately to the height of at least one adjacent purlin, preferably of two adjacent purlins.

Such a configuration is conceivable for roof coverings which have a certain

-3- ~. [i @ pr malleability, such as sheet metal. If the height of the mounting element is less he than the height of at least one adjacent purlin, the roof covering is displaced further downwards by the mounting in the region of the relevant mounting o element. If, on the other hand, the height of the mounting element is greater = 5s than the height of at least one adjacent purin, the roof covering is slightly @ raised in the region of the relevant mounting element. o

It is, of course, also possible for the height of at least one mounting element to ~ correspond to the height at least of one adjacent purlin, preferably of two adjacent purlins. Thus, the upper side of the purlins and the upper side of the mounting element form a plane.

At least one mounting element can be provided with at least one support surface, preferably horizontally oriented, interacting with the top side of the truss, at least one top surface, preferably a horizontal mounting surface, and at least one mounting surface.

At least one mounting element can have a square cross-section. In this case, the mounting element has two connecting regions which connect the support surface and the mounting surface to one another.

At least one mounting element can rest on the upper side of the truss in the mounted state. This results in a larger contact area between the mounting element and the truss, so that the weight of, among other things, the solar modules can be applied to the truss over a larger area.

At least one truss can have a horizontally oriented top side. For example, the truss may be in the form of an upright T-beam, or as a double T-girder.

The supporting surface of at least one mounting element can protrude laterally on the side of the truss on at least one side, preferably on both sides, and at least one recess for passing through a bolt for a clamping fastening of the mounting element on the side of the truss can be provided.

Corresponding reference characters are used for identical or similar components in all the figures.

Fig. 1 shows a plan view of a roof constructed as a gabled roof. The gabled roof consists of two roof halves which are aligned at an angle to one another and interact along a roof ridge. In the execution example shown, the roof structure in each roof half has two trusses 1 which are orthogonal to the roof ridge. The corresponding trusses 1 of the two roof halves abut one another in the roof ridge region. Of course, other roof shapes, such as flat roofs or roof structures that are only inclined to one side, are also possible.

On the upper side, three purlins 2 are arranged on the trusses 1 in the execution example. Each purlin 2 can extend from one side to the other side of the roof and can thus be designed as a single part. However, it is also quite possible that the purlins 2 are arranged in the region of a truss 1, as shown in fig. 1 — abutting flush against one another. Other arrangements of the purlins 2 on the trusses 1 are, of course, also possible. For example, the purlins 2 can be arranged overlapping one another on the trusses 1, for example. The purlins 2 are fastened on the upper side of the truss 1 by means of suitable fastening elements.

In fig. 2, various profiles of a purlin 2 are shown, while fig. 3 shows different profiles of a truss 1. As shown in figs. 2 and 3, the purlins 2 and/or the trusses

Pod 1 can, for example, have the form of a T-profile or a double girder. Of course, both profiles can also have a rectangular cross-section. ”

As shown in fig. 1, a mounting element 3, which in the shown execution = : example has a square cross-section, is located adjacent to a purlin 2. Such a = mounting element 3 is shown in detail in fig. 11. In the execution example a shown, the mounting element 3 has a horizontally oriented bearing surface 4 br interacting with the underside of truss 1, a mounting surface 5 arranged on the ~ upper side and two connecting areas 6 which are laterally connected to the support surface 4 on the lower side and the mounting surface 5 on the top side. In the execution example shown, the height of the mounting element 3 corresponds to the height of the adjacent purlin(s) 2 so that the upper side of the mounted purlins 2 and the mounting surfaces 5 of the assembled mounting elements 3 lie in one plane.

The bearing surface 4 of mounting element 3 is dimensioned in terms of its size so that the bearing surface 4 protrudes laterally over truss 1 on both sides in the assembled state. In each laterally protruding portion 7, two recesses 8 are provided for the passage of a bolt 9 for a clamping fastening of the mounting element 3 to truss 1. Such a clamping fastening is shown in fig. 10.

In the execution example shown, truss 1 is designed as a standard [-beam.

In the assembly of mounting element 3, two clamping brackets 10 are fastened on both sides of truss 1 by means of the bolts 9 in such a way that the clamping jaws 10 engage behind the lower edge of the upper side of truss 1 in the edge region. Bolts 9 are secured by means of nuts 11.

Fig. 4 shows the roof without roof covering 12 in plan view. The three purlins 2 are clearly visible. Two transverse rails 13 running parallel to the purlins 2 are also visible that, as shown in fig. 7, are fastened to mounting element 3 by means of a profile 14 via a fastening element 15.
