Description

The Innovation relates to a stand of a solar module accordingly the preamble of claim 1.

Generic stands are also known as so-called solar pans and example in the DE 10 2006 026 297 B3 disclosed. The solar tubs have a circumferential obliquely rising from the front to the rear frame, which forms the support surface for receiving a solar module.

at the generic stand is disadvantageous that additional strivings are needed between the solar module and the stand are arranged, which the Assembly effort for the completion of a raised Solar module increases and also due to additional Material costs the elevated solar panel economically disadvantageous affected. Furthermore, it is disadvantageous that the generic Stand due to its trough-like design comparatively large volume occupies. When as a solar module a photovoltaic module is used, is also still disadvantageous that the trough-like closed configuration of the stand ventilation of the solar module difficult, which is warmer Weather adversely affect the efficiency of the solar module can.

Of the Innovation is the object of a generic Stand to improve so that this as possible is designed inexpensively, a possible low storage space, and with as simple as possible and inexpensive means within a short time the assembly of the Solar module as an elevated solar module allows.

These Task is characterized by a stand with the characteristics of Claim 1 solved.

The Innovation suggests in other words, the elevation of the solar module and its oblique to the horizontal running To allow alignment by a holding surface which is designed as a surface element and opposite the horizontal can be arranged obliquely, where they from its upper part then by means of a support surface supported at the bottom. Because of the support surface and the support surface as two sections of the same surface element are configured, the surface element can first be transported as a flat plate. The angling between Holding surface and support surface provided is in place during installation on easy Way thereby allowing that between these two sections a bend line is provided.

The Installation of the holding surface in its oblique arrangement is thus very simple and time-saving feasible. In that, similar to a pitched roof two oblique are provided to each other arranged surfaces, namely the holding surface on the one hand and the support surface On the other hand, a space below these two becomes angled created to each other arranged surfaces, the air flow below the solar module allows, so this either cooled by wind or by a self-adjusting thermals can be and therefore the best possible efficiencies also may have in hot weather.

The Support surface can be specially adapted to the format of the Solar module adapted, but it can also be smaller or larger modules are mounted, for example by slotted rails or C-shaped profiled support rails be used.

Advantageous can also be the bottom as a section of the same surface element be designed as the holding surface and the supporting surface, so that overall the entire stand as a single Plate can be designed. Here are dividing lines, such. B. Stamping lines between the ground and the holding surface and provided the support surface, so that, for example the floor can be aligned lying flat and in contrast the Holding surface and the support surface erect and each aligned obliquely to the horizontal running can be.

While the dividing line a mobility of the separated sections allow the surface element independently, are the fold lines as lines of weakness. designed, along which still the sections of the surface element remain connected, which, however, the bending stiffness reduce the surface element along these fold lines, so that these different sections with a low resistance can be angled against each other. Because of this low Resistance is less than the bending resistance of the surface element outside the fold lines, can by means of the fold lines be precisely defined as the individual against each other bent portions of the surface element shaped and should be measured.

preferably low transport costs and the simplest possible and thus time-saving assembly is advantageously effected by that configured the surface element as a lightweight composite panel is. Such a composite plate has an upper and a lower Cover layer on and an interposed intermediate layer, for reasons of weight saving cavities having.

there the intermediate layer can advantageously have nubs, which are created by a so-called knobbed ge. Such a knobbed plate has a plate surface or base surface, from which protrudes a variety of nubs. For example can such a studded plate made of plastic and in Deep drawing process can be produced. It can either be a single Knob plate between the two cover layers of the composite panel be provided or it can be provided two studded plates be. in both cases it is provided that the plate surface the nubbed plate with a cover layer of the surface element is firmly connected. If two studded plates are provided, extend the nubs are not each up to an opposite Top layer, but to each other Noppenplatte and are firmly connected with this, while when used only a nubbed the nubs of this one nubbed plate with a the two outer layers are firmly connected. As a solid connection is to look at a bond or a weld, for example, as they can be achieved for example by means of ultrasonic welding is.

There the proposed stand as lying flat Blank can be transported and erected only at the installation site is, the maximum transport capacity of a transport vehicle can be optimal be exploited, especially if due to the lightweight construction of the used for the stand area element the storage space of the transport vehicle also in terms of permissible Transport weight can be fully utilized.

Especially can be advantageously provided, the flat surface elements already assemble with the solar modules, so that at the site when erecting the stand automatically the solar modules be aligned correctly and not afterwards attached to the initially erected stands Need to become. For example, like a foil flat modules are glued directly to the support surface.

at larger layer thicknesses of the solar modules or the Laminates may be advantageously provided in the support surface to provide an impression with a layer thickness, the is less than the usual layer thickness of the surface element and in particular the holding surface. The imprint may for example be designed as a rectangle, namely rectangular Solar modules are used and is particular in terms of their Dimensions adapted to the dimensions of the solar module such that the solar module in the impression of the holding surface can be used.

there may be provided in particular that not only the area dimensions the imprint, so for example length and Width of the imprint, for the inclusion of the solar module are suitably designed, but that in particular the depth the imprint is chosen such that the solar module completely immersed in the holding surface, so flush with the surface of the support surface can. In this way you can not without loss of storage space only the stands themselves as space-saving as possible but it can be prefabricated at the factory, provided with solar modules stand in the form initially flat surface elements save space be transported, with the pre-assembly of the stand with the solar modules the reliable fixing of the solar modules ensures, as this packaging, for example, weatherproof can be done in a factory building. When setting up the stands are then only the electrical connections of the solar modules to connect with each other.

These above-described assembly of the stand with the solar modules may be provided in particular when electrical, ie photovoltaic solar modules Use, because these can be called so-called laminates be made with a relatively small layer thickness, for example with a layer thickness of about 6 to 7 mm. The surface elements the stand can by contrast, for example have a layer thickness of about 10 mm, and especially when the surface elements are made of plastic, can the indentations in a simple way by means of a heated Stamp are introduced into the surface element. The by the impression made compaction of the surface element advantageously causes a reduction of the thermal insulation effect, so that the desired cooling effect for the back of the Solar module is favored by this, also can in the area of impression also recesses in the form of Breakthroughs may be provided, for example, in the Imprinted to be in this way a Air duct directly to the back of the solar module to enable.

The Surface element can advantageously be configured in such a way that it has a frame-like bottom portion, so that this embodiment surrounds a recess as a frame of the bottom. This recess is, for example, by the above-mentioned Dividing lines defined, which simplifies an approximately U-shaped Course can have. This way will be within the bottom formed a very large tab, which means a bend line can connect to the ground and in turn by another crease line in the holding surface on the one hand and the support surface is divided on the other hand.

Advantageously, the support surface in turn again in the obliquely upwards to the support surface extending support portion on the one hand and be divided into a flat-lying latching portion, said latching portion and the bottom cooperate with each other in such a way that the latching portion is held in a certain position on the ground and thus the obliquely upright position of the support surface and the To maintain the support section. For this purpose, the interaction between locking portion and the ground may be provided by means of a toothing, which is formed by mutually engaging behind jumps on the latching portion on the one hand and on the ground on the other. In this case, recesses in the bottom are designed such that the latching section allows on the one hand a flat arrangement of the entire surface element, ie a flat arrangement of the support surface and the support surface, and wherein the bottom further comprises recesses into which the projections of the latching portion can engage when in a so-called functional position of the surface element, the holding surface and the support surface are placed so that then rest the projections of the support surface second projections of the soil.

Advantageous The floor can not only be designed as a frame and inside have projections, so to the mentioned Lug out, the holding surface and the support surface but the ground can also protrude at one of its outer edges and on an opposite outer edge have complementary indentations, so that two similar designed and juxtaposed stand with these Projections and recesses can form a composite. That way, a bunch of uprights can coexist or in a row and by the formation of a Composite allow a safe as possible, For example, against contrasting forces at appropriate Wind loads to be secured.

there Advantageously, the projections can be a regular one Undercut form so that the adjacent and interconnected Stands can not be pulled apart, but only in one direction across the undercuts be separated from each other.

alternative to such a composite, directly by the corresponding molded stand can be an indirect Composite of two stands created by this mitein connected by specially provided connecting means mitein other be, for example, by metal profiles such. B. aluminum rails, which are screwed with two stands each.

apart from the fact that the neighboring stands are connected to each other can be a backup against lifting forces be done by, for example, that the bottom of the stand is complained of, for example with stone slabs o. The like., Like this in itself also from the generic solar tubs is known that with a ballast material, such as gravel o. The like. can be filled. A particularly big one Support surface for such weighting material can be advantageously formed by the holding surface is designed substantially U-shaped, for example by a U-shaped parting line, which remain a tab leaves, which can be expected to the ground when the U-shaped Holding surface is placed at an angle. This remaining So-called bottom flap can on the one hand with ballast material be complained, so a particularly stable hold of the stand to ensure on the ground, and second places Make sure that much of the solar module is not back covered by the holding surface, so that accordingly a good ventilation of the solar module and a accordingly good cooling of the solar module is possible.

If Reliable protection of the solar modules and the stands can be given against lifting wind loads, a side cover be provided for the stand, which is the penetration of wind under the support surface and the support surface difficult. With mounted holding and support surface results in a lateral triangle opening of the stand, which can be covered with the help of this side cover. there can be provided, the side cover is not complete windproof or completely windproof to the holding and To connect support surfaces, so that through the side cover, although the wind speeds significantly reduces who else, who are otherwise below the support and support surfaces but could still adjust the air circulation below the support and support surfaces is made possible so that, for example, a heat accumulation below the solar modules avoided can be.

One significant advantage proposed by the stand is that as a flat, foldable blank from a Semi-finished products are made in the form of a plate and thus without larger Tool investment costs the manufacture in different Allow sizes. For example, you can Metallic stands by comparatively simple reprogramming a laser cutting system in different sizes getting produced. If the stands are made of plastic studded plates are formed, which are manufactured as semi-finished and with little tool wear on the desired dimension can be cut, is also easily the production of different sized Stand possible.

One Embodiment of the innovation is based on the purely schematic Illustrations explained in more detail below. there shows

1 a perspective view of a stand in its functional position,

2 the stand of 1 in the same perspective, but equipped with a solar module,

3 the stand of 2 seen from the back, and

4 similar in a perspective 2 a series of several stands, each equipped with a solar module.

In the drawings is with 1 in each case a total of a stand called, for receiving a solar module 2 serves. The stand is made entirely from a surface element in the form of a lightweight composite panel, this surface element is divided by crease lines and parting lines into several different sections:
A frame-like, flat lying on the ground floor 3 not only forms the actual frame, but also a bottom flap 4 out, and is over two crease lines 5 with a total of approximately U-shaped holding surface 6 connected, due to their U-shaped configuration, the bottom flap 4 surrounds.

The holding surface 6 is at the erected in functional position stand 1 at an angle from the bend lines 5 oriented upward and adjacent to another crease line 7 to a support surface 8th which slopes downwards from the crease line 7 downwardly extending support section 9 and an adjoining, resting flat on the ground resting section 10 having. The resting section 10 closes to the support section 9 also over a bend line 11 at.

The resting section 10 has lateral projections 12 on, which with corresponding indentations 14 and projections 15 at the frame 3 interact. In this way, the latching section 10 safe to move within the frame 3 set so that the obliquely upright arrangement of the support surface 6 and the support section 9 the support surface 8th be reliably maintained. Alternatively, it may be provided, the latching section 10 at the frame 3 by additional connecting means such. B. tabs set, in particular metallic tabs, both at the locking portion 10 as well as on the frame 3 are attached. However, such tabs can also in addition to that by the projections 12 , the indentations 14 and the projections 15 created composite may be provided as security elements, so that the composite can not accidentally come loose.

Out 3 it can be seen that the support section 9 the support surface 8th forms a windbreak, so that from behind against the solar module 2 flowing wind does not move unhindered under the solar module 2 and can lead to undesirable large contrasting forces, which the stability of the elevated solar module 2 could endanger.

In the 2 and 3 is a solar module 2 shown, which laterally across the width of the support surface 6 extends out and which at least up to the upper edge of the support surface 6 So up to the break line 7 extends. In contrast, in 4 shown that solar modules 2 can be mounted, extending neither to the lower crease line 5 the holding surface still up to the upper bend line 7 the holding surface 6 extend and therefore in a particularly simple manner by means of approximately S-shaped or Z-shaped tabs 16 at the holding surface 6 can be attached.

Out 4 is also evident that on the outer edges of the frame 3 provided, complementary projections 17 and indentations 18 are provided so that two adjacent, similar stand 1 create a real network and also the formation of a network of more than just two stands 1 enable. projections 17 expand outward so that they form undercuts which prevent two connected stands 1 can be pulled apart horizontally.
