State of the art

Devices for fixing solar and photovoltaic modules on roofs are known in various forms and by various manufacturers, in particular for elevation and as an accessory for solar modules ( DE 10 2005 033 780 A1 ).

The devices relate in the majority to universal mounting systems or special solutions for special applications such as shelters and carports. Self-supporting structures are known as a mounting system of beams, beams and transverse stiffeners in lightweight construction ( DE 20 2007 008 614 U1 ; DE 20119629 U1 ; DE 20 2008 014 274 U1 ) which are mounted on the buildings and roofs and / or before or afterwards provided with the solar and photovoltaic modules or are.

In these cases, a suitable load-bearing roof construction and / or extensive installation on the buildings and roofs is necessary.

task

The present invention has for its object to make self-supporting module support with functional modules of regenerative energy production as finished units with few load transfer points on buildings and roofs, which can be done with little installation effort and optionally also a relief of the roof and / or a gain of Roof construction consists in the static.

The aim is also to make hitherto poorly suitable roofs for energy production usable, which would have previously reached only after additional static or other structural reconstructions of the suitability. Self-supporting in this context means the partial or total overvoltage of roofs and buildings. Furthermore, the possibility should exist that on the self-supporting module supports ( 1 ) with function modules ( 2 ) and their supporting structures and / or rails ( 4 ) additional components are attached to extend the positive overall characteristics. This concerns additional components for the installation, inspection, securing, maintenance, cleaning and care of the system as well as anti-theft devices and locks.

embodiment

Self-supporting module carriers for functional modules of regenerative energy generation, in particular for solar and photovoltaic systems, are an arrangement for the structural design of power generation systems which are installed on roofs or buildings or in the open field.

Based on the goal to make hitherto poorly suitable roofs for energy production, which would have reached the suitability only after additional static or other structural reconstructions, an embodiment is described, which is suitable for static undersized pitched roofs with too weak rafter design or too little static reserve for additional application of a solar system, or have too little static reserves in the wind load to make usable.

Static reserve means the possibility of additional loads being applied to the existing roof or building. The possibility of applying additional loads, load points and load types can be provided by a stability check with static calculation of the existing roof or building.

The selected embodiment for pitched roof describes a self-supporting module carrier ( 1 ), top with carrying structures and rails ( 4 ) on the roof ridge and on the bottom of supporting structures and rails ( 4 ), which provide an optimal load transfer directly to the outer wall ( 1 ).

Self-supporting in this context means the partial or total overvoltage of roofs and buildings without the roof surface is loaded statically between or outside the load transfer points. In addition to the attachment points, roof and building dimensions, the self-supporting module carrier ( 1 ) also have projections to the sides and thus increase the usable area. Typically, the module carrier also extends beyond the roof ridge or increases the bottom or side roof overhang.

The upper supporting structures and rails ( 4 ) on the roof ridge consist of a support structure, which may be formed as a U-profile and has load-bearing properties for roof reinforcement and load distribution. The support structure can be fixed by screws on stanchions ( 7 ), which under the roof over tabs ( 8th ) can be connected to the rafters on both sides. This connection can be used as bilateral load dissipation into the rafters or as a base for load distribution downwards. On the support structure are the upper mounting rails, which can also be designed as angle rail or quick-mounting device. On these mounting rails are the self-supporting module carrier ( 1 ) also optionally laterally movable and movable. The height of the support points can be designed variably so that there is an improvement in the reception angle or a particularly good cooling by an enlarged air space with better circulation properties among the functional modules ( 2 ) consists.

The lower support structures and rails ( 4 ), on or on building walls or in static Lastableitender connection to support walls or load dissipation points, consist of mounting rails, which may be formed as an angle profile and can have properties for roof reinforcement and load distribution roof fastening elements. The mounting rails can be fastened to the roof or building via roofing or screws. On these mounting rails are the self-supporting module carrier ( 1 ) also optionally laterally movable and movable.

During production and pre-assembly, the finished self-supporting module carriers ( 1 ) already with brackets and fasteners for the functional modules ( 5 ) and the functional modules ( 2 ) and their interconnection. Brackets for transport, application and for quick assembly of the module carrier complete the arrangement and are designed so that the finished self-supporting module carrier can be moved on the roof. Due to the displaceability, it is sufficient if the application of the finished self-supporting module carrier ( 1 ) on the roof or building in one place is possible.

In the described embodiment, the one or more finished self-supporting module carrier ( 1 ) with the applied function modules ( 2 ) with a lift or crane on the roof or building and in the rails ( 9 ) hung on top of the ridge and down over the outer wall and fastened with anti-theft devices. The one or more module carriers are conveniently scaled in advance to the dimensions of the roof size and can be applied in a mounting passage on the creek or building. In the described embodiment, several finished self-supporting module carriers are applied to the roof or building. This spans and covers a larger area.

In the described embodiment, the finished self-supporting module carrier ( 1 ) with the holders for the modules ( 5 ) equipped in such a way that they are rails, are inserted in the fitting screws for attaching the function modules and they are fitted with quick-fit fitting nuts and anti-theft devices and / or in the function modules ( 2 ) are inserted directly.

In the described embodiment, useful additional components are fixed, movable or optionally arranged.

On the self-supporting module carriers ( 1 ) and the functional modules ( 2 ) their supporting structures and / or rails ( 4 ) and / or the load transfer points ( 3 ) ducts and pipes for supply lines, cables and other components are mounted in such a way that in the pre-assembly partially or the entire installation is applied, connected and put into operation.

In the described embodiment is on the upper support structures ( 4 ) a catwalk ( 10 ) mounted along the roof ridge, which is laterally offset downwards and has particularly good on-board characteristics, since it is delimited on the ridge side by the superior functional modules like a railing. On the side turned away from the ridge are optionally raised rails ( 11 ) for safety lines ( 12 ) and brackets ( 13 ) for an optional railing ( 14 ) appropriate.

In the described embodiment, on the self-supporting module supports ( 1 ) and on the supporting structures ( 4 ) Junction boxes and switchgear ( 18 ) for maintenance and activation of the functional modules ( 2 ) available. For cleaning and care facilities, optionally adapted guide rails ( 15 ) on which the devices or devices are held by hooks, trolleys or other guide means and are movable over the surfaces of the functional modules.

In the described embodiment, on the self-supporting module supports ( 1 ) and / or on the supporting structures ( 4 ) movable devices that have an automatic drive ( 17 ). Snow guards and / or vibrators are designed in their functionality, which is the controllability of the protection against falling snow and at the same time the targeted shaking of the snow cover.

Further modifications of the description will be apparent to those skilled in the project related art. The description shall describe the relevant principles of the protection claim and represent the main applications.
