Description

The present invention relates to a module mounting system for mounting modules on a lightweight construction hall, which has a framework structure made of framework profiles and a membrane as a roof cover.Various mounting systems for sloping roofs are available on the market for mounting energy modules. However, none of these systems is suitable for lightweight halls, made of metal or wood frameworks and membranes, for example. If a commercially available system were used for such membrane roofs, these systems would have to be modified and fastened by means of fixing elements which penetrate the membrane.It is an object of the present invention to provide a module mounting system for a lightweight construction shop, which permits the mounting of a module as far as possible without penetration through the membrane.This object is achieved by a module mounting system according to claim 1. Advantageous embodiments and various exemplary embodiments and a lightweight construction shop with a module mounting system are described in the dependent claims.According to the present invention, a module mounting system is provided with at least one fastening element and at least one holding means attached to the outside of the membrane in order to be able to connect a module carrier preferably in a quick and uncomplicated manner. The module carrier is, for example, part of a module carrier system for mounting energy modules in the form of photovoltaic modules and / or thermal solar modules. The holding means can be attached to the outside of the membrane without penetration. For example, the holding means is free of a screw penetrating the membrane.The module mounting system has, for example, pockets, flaps, cords and / or fixation points which are open on one side and can be respectively attached to the positions of the framework, to which a fastening element, for example a profile which is particularly suitable for this purpose, is respectively fastened, which is held by means of holding means. Module supports, for example special profiles, are then fastened to these fixed profiles, which are supported in a cantilevered or minimal manner up to the next truss part. The grid of the latticework parts can have different distances. In addition to the fixing of the module carrier systems, crash safety systems, service route systems and / or cable trays can also be integrated.On the membrane, which can be rolled or folded, for example, the mounting points are connected mechanically, thermally or chemically with a certain strength. The mounting points are ideally adapted in size according to the system variant in such a way that, for example, base profiles can be fixed without problems. During assembly, the profiles to be mounted thereon are brought onto the membrane after completion of the lightweight shop and are fastened mechanically, thermally or chemically.The module mounting system can be designed in such a way that it allows simple and rapid fixing of a module carrier, reduces the assembly effort at the mounting location, is simple to handle and enables variable positioning of the modules. Crash systems, service paths and cable conduits can also be integrated.In a first variant, the fixing is effected by means of pockets and push-in profiles mounted on the membrane, wherein the pocket can be tensioned by an additional profile which is fastened in a depression in the push-in profile. The module profile as a carrier for a module is then fastened on the insert profile.In another variant, the fixation is effected by means of pockets and push-in profiles mounted on the membrane, wherein the pocket can be tensioned by an additional profile which is placed above it. The module profile is then fastened on the insert profile.In a further variant, it is also possible to prestress the insert profiles via the module carriers, for example module profiles. In this version, the insert profiles are held in place by means of a temporary holding system until the module carriers are finally mounted.According to yet another embodiment variant, plastic strings are attached to the membrane, on which base profiles are pushed or clamped. A base profile provides a base for a module carrier, e.g. module profile, which is mountable thereon.A further embodiment variant provides membrane strips attached to the membrane, wherein a base profile is pushed on and / or clamped to it in order to form a base for mounting the module carriers, e.g. module profiles.An additional variant provides fixation points which are attached to the membrane to which base profiles, rods and / or wire cables are fastened. The module carriers, e.g. module profiles, can then be mounted thereon.A mechanical holding system without pockets can also represent a further variant. Under this, a membrane can be envisaged which has one or more pre-assembled fastening elements in the form of pads which enable the module carriers, e.g. module mounting profiles, to be mounted. These pads may constitute the mechanical fixation. These pads need not necessarily be incorporated into the membrane. They can also be part of the profiles.In addition to the above-mentioned solutions, other variants are also possible which are not explicitly mentioned in this document.The membrane, which may be rolled or foldable, for example, can be prefabricated on large surfaces. During installation, the pieces to be laid can be cut to size beforehand from storage or else at the installation site. The pieces to be laid are positioned and tensioned on the framework structure. Fine tuning can be performed when installing the components, such as stop points of the crash safety device or the module mounting system.The module mounting system can be used for mounting an energy module system or a plurality of energy module systems having a plurality of energy modules which are arranged on module carriers, wherein an energy module system having straight profiles can also be foldable. The module mounting system is suitable for all types of flat or also flexible, bent energy modules, in particular for photovoltaic modules and thermal solar modules.The invention is illustrated by several embodiments. The individual technical features of one embodiment variant can also be used in combination with another embodiment variant having the advantages set forth.

The module carriers can also be designed differently and serve for carrying other modules, in particular power modules.FIG. 1 shows a possible complete construction of a module mounting system for lightweight halls. The truss profile 1 belongs to the truss structure of the hall on which the diaphragm 2 is laid. The pocket variant is shown here, in which the insert profiles 4 are held via the membrane pockets 3 attached. The respective membrane pocket 3 is formed by a membrane tab which is connected to the membrane 2 on two sides. Clamps 5, which are fixed by a self-drilling screw 8, hold the collector profiles 6 serving as module carriers. The respective insert profile 4 serves as a fastening element to which a module carrier 6 can be fastened. In this variant, the collectors 7 are inserted into the collector profiles 6. However, there are also other mounting profile solutions for mounting modules.FIG. 2 shows a first embodiment variant of the module mounting system for lightweight halls with an additional clamping profile 9. The truss profile 1 belongs to the truss structure of the hall on which the diaphragm 2 is pulled. Initially, membrane pockets 3 are applied at the positions of the truss profiles 1, into which the insert profiles 4' are pushed after completion of the hall. These are then fixed by means of inner clamping profile 9 and self-drilling screw 10, as a result of which the membrane pockets 3 are clamped. For this purpose, an insert profile 4' has a depression 4a into which the clamping profile 9 can be inserted.As soon as all the insert profiles 4' are securely fastened, the collector profiles 6 can be mounted and the collectors 7 fitted.FIG. 3 shows a further embodiment variant of the module mounting system for lightweight halls with an additional clamping profile 11. The truss profile 1 belongs to the truss structure of the hall on which the diaphragm 2 is pulled. Initially, membrane pockets 3 are applied at the positions of the truss profiles 1, into which the insert profiles 4 are pushed after completion of the hall. These are then fixed by means of an outer clamping profile 11 and self-drilling screw 10, as a result of which the membrane pockets 3 are clamped. As soon as all the insert profiles 4 are securely fastened, the collector profiles 6 can be mounted and the collectors 7 fitted.FIG. 4 shows a further embodiment variant of the module mounting system for lightweight halls with a plastic cord 13. The truss profile 1 belongs to the truss structure of the hall on which the diaphragm 2 is pulled. Previously, plastic cords 13 are attached to the positions of the truss profiles 1 by means of membrane flaps 12, onto which a round cord base profile 14 is then attached in each case. This can be done by means of the drawing-in process or as a clamping variant. Once all the cord base profiles 14 have been securely fastened, the commutator profiles 6 can be mounted and the commutators 7 fitted. A round cord base profile 14 serves as a fastening element for a module carrier 6 and has a planar upper side here.FIG. 5 shows a further embodiment variant of the module mounting system for lightweight halls with a double membrane tab 15. The truss profile 1 belongs to the truss structure of the hall on which the diaphragm 2 is pulled.

The base clamping profiles 16 and the clamping block 17 are fixed onto these double membrane flaps 15 by means of clamping screw 18. In the case of two pieces, as shown here, the respective membrane flap 15 is connected to the membrane 2 only on one side, so that a free membrane flap section is formed, to which the fastening element 16 can be fastened. If only one piece is provided, this is preferably connected to the membrane 2 on two sides, so that a membrane flap middle part is provided therebetween for fastening the fastening element 16. Once all base clamping profiles 16 have been securely fastened, the collector profiles 6 can be mounted and the collectors 7 fitted.FIG. 6 shows a further embodiment variant of the module mounting system for lightweight construction halls with fixation points 20.
