Description

[0001] Carrier system

[0002] The invention relates to a carrier system according to the preamble of patent claim 1.

[0003] A support system is known from the prior art, comprising a plurality of photovoltaic modules and support elements. The support elements are arranged at a distance from one another and are each connected to a soil surface in a force-fitting and / or form-fitting manner. The support elements are each connected to a bearing element for supporting at least one of the photovoltaic modules, wherein the respective bearing element has at least a first bearing section for supporting at least the first photovoltaic module and a second bearing section for supporting at least the second and / or one further photovoltaic module. The respective support element is positively connected to at least one soil connection element, wherein the soil connection element rests on the soil surface.Furthermore, the ground connection element has at least one first recess for the passage of the support element, wherein the support element is designed as a fastening element which is connected to the ground surface and / or the ground in a force-fitting and / or form-fitting manner. Problems with these support systems arise when, for example, the ground is less stable, in particular when it is very soft, fine-grained and sandy. In this case, there is a possibility that the fastening elements designed as support elements can no longer ensure stable mounting of the support system because they could sink into the ground on their own due to the load of the photovoltaic modules. For example, during a storm, the support system, in particular its support elements, could become detached from the ground and change the location and position of the support system.This is very disadvantageous because the photovoltaic modules could then be shifted in such a way that they are at a bad angle with respect to the sun's radiation, thus impairing their energy production.

[0004] For this reason, in the prior art, tubular guide elements are welded to the floor connection elements, which are designed to loosely support additional fastening elements that serve to additionally fasten and secure the support system. The additional welding of the tubular guide elements is very cost-intensive and leads to increased labor during the production of the support system. The weld seams must also be protected against corrosion, which creates further additional labor during the production of the support system. Therefore, the object of the invention is to provide a cost-effective and structurally simplified support system that ensures a stable position of the photovoltaic modules regardless of external environmental influences.

[0005] The problem is solved by patent claim 1, in particular by the characterizing part of patent claim 1. A support system is provided which comprises at least two photovoltaic modules and at least two support elements, wherein the support elements are arranged at a distance from one another and are each connected in a force-fitting and / or form-fitting manner to a floor surface of a floor and / or to the floor, wherein the support elements are each connected to a bearing element for supporting at least one of the photovoltaic modules, wherein the respective bearing element has at least a first bearing section for supporting at least the first photovoltaic module and / or a second bearing section for supporting at least the second and / or a further photovoltaic module, wherein the respective support element is connected in a form-fitting and / or force-fitting and / or material-fitting manner to at least one floor connection element,wherein the floor connection element rests on the floor surface or is at least partially or completely arranged within the floor, wherein the floor connection element has at least one first recess for the passage of the support element, wherein the support element is designed as a fastening element which is connected to the floor surface and / or the floor in a force-fitting and / or positive-locking manner, wherein the floor connection element comprises at least one second recess spaced from the first recess for the passage of an additional fastening element, wherein the additional fastening element is connected to the floor connection element in a force-fitting and / or positive-locking manner and is connected to the floor surface and / or the floor in a force-fitting and / or positive-locking manner.

[0006] The first recess and / or at least the second recess of the floor connection element can be designed as an opening. This first recess and / or at least the second recess can, for example, already be formed during manufacture of the floor connection element by designing the appropriate tool for forming the first recess and / or at least the second recess. Subsequent reworking of the floor connection element for the storage and passage of the additional fastening elements can thus become obsolete and can therefore reduce the manufacturing costs of the support system. The transport and storage of the floor connection elements can also be carried out in a much more space-saving manner, as there is no need for extremely protruding elements from the floor connection element, which would prevent the floor connection elements from being stacked on top of one another in a space-saving manner, for example in a truck or in a Lagarhall©.Since the floor connecting elements can already be made of a corrosion-resistant material, the visible edge areas of the first recess and / or second recess can also be made corrosion-proof.

[0007] Preferably, the at least second recess is arranged in the floor connection element such that the floor connection element has a flat surface, in particular a plane surface. This ensures easy passage of the additional fastening element through the floor connection element, and the flat surface also reduces the risk of injury to a worker during assembly of the additional fastening elements.

[0008] Furthermore, it has been advantageously shown that the insertion and / or storage of the respective additional fastening elements in the respective second recesses of the floor connection element is sufficient to ensure stable support of the entire support system. Particularly due to the increased material costs and particularly with regard to the materials or metals to be processed, it is very important to design the overall structure as cost-effectively as possible. The additional fastening elements can, for example, have a length of 30 cm to 120 cm. Preferably, each support element is longer than each additional fastening element in order to provide a cost-effective construction of the support system.

[0009] It is also conceivable that the diameter of the first recess is always larger than the diameter of at least the second recess, in particular of all recesses on the floor connecting element.

[0010] It is also possible for the diameter of the support element to always be larger than the diameter of the at least second recess designed to pass through the additional fastening element. This advantageously prevents the support element from being mistakenly used as an additional fastening element. This can be particularly useful if the support element and the additional fastening element have different strengths and constructions. Furthermore, the support element and / or the additional fastening element can be designed, for example, as a rod, which at least partially has a corrugation on its outer side, which extends, for example, in a spiral shape on the support element designed, for example, as a rod and / or the additional fastening element. The corrugation can additionally serve to ensure a firm, secure, and stable hold of the support element and / or the additional fastening element.

[0011] Alternatively, the at least one additional fastening element can be structurally substantially identical to the support element arranged in the floor connection element. This allows the number of variants of the support system components to be reduced, which in turn reduces the manufacturing costs.

[0012] According to a preferred embodiment of the support system, the at least one additional fastening element and / or the support element can be pointed at at least one of its ends. This ensures simple and secure installation of the support system. Due to at least one pointed end of the additional fastening element, it can be easily and precisely guided into and / or through the second recess and anchored within the floor with less effort. The at least one pointed end of the additional fastening element and / or the support element can therefore be designed as a guide element. Likewise, due to its pointed end, the support element can be anchored within the floor, in particular by hammering, with less effort.

[0013] According to a further preferred embodiment of the support system, the floor connection element can be designed as an at least three-sided, preferably four-sided pyramid, which comprises at least three side planes, preferably four side planes, wherein the pyramid has a truncated pyramid which is designed to accommodate the first recess and is designed to pass through the support element, wherein the second recess for passing through the additional fastening element is arranged in at least one side plane. The truncated pyramid can, for example, be designed as a hollow cylinder. The hollow cylinder can advantageously serve for the secure mounting of the support element. Alternatively, the truncated pyramid can be designed merely as a simple opening which is designed as the first recess.

[0014] Preferably, a recess for the respective additional fastening element can be formed in each side plane of the pyramid. Due to the pyramid-shaped design of the ground connection element, water, for example, can flow more effectively down the inclined side planes into the ground or onto the ground surface. This minimizes the accumulation of water on the ground connection element, which could reduce the service life of the ground connection element and / or the support element and / or the at least one additional fastening element. Furthermore, the inclined side planes of the pyramid, in conjunction with the respective additional fastening element, have a positive effect because the angle for inserting the additional fastening elements into the ground can be automatically predetermined due to the inclined side planes. This ensures stable fastening and anchoring of the support system even in softer soils.Incorrect assembly of the additional fastening elements by the worker can thus be advantageously prevented. In addition, the pyramid-shaped design of the floor connection element ensures stable mounting of the at least one additional fastening element and / or the support element. The pyramid-shaped floor connection element allows the structure to be made more rigid, allowing for better compensation of the forces acting on the floor connection element. This can be particularly important when at least one additional fastening element is used, as it could result in improved force distribution on the floor connection element.

[0015] According to a further preferred embodiment of the support system, a limiting element can be provided which is connected to the additional fastening element in a materially bonded and / or form-fitting and / or friction-locking manner. The limiting element arranged on the additional fastening element can advantageously simplify the assembly of the additional fastening element to the floor connection element. Likewise, penetration of the additional fastening element into the floor can be prevented, in which case, in an extreme case, the additional fastening element is arranged completely beneath the floor connection element after assembly, thus providing little or no additional anchoring of the support system to the floor and / or the floor surface. The limiting element can therefore rest on the floor connection element after assembly, thus advantageously improving the stability of the entire support system.It is also conceivable that the boundary element is arranged at a distance from the floor connection element after assembly.

[0016] According to a further preferred embodiment of the support system, it can be provided that the limiting element arranged on the additional fastening element, particularly in the assembled state, is not designed to be passable through the first and / or second recess. The limiting element can thus be designed as a safety element to prevent the additional fastening element from completely penetrating the floor connection element. Incorrect assembly of the additional fastening element with the floor connection element by the worker can thus be advantageously prevented.

[0017] The construction of the support system can be very simple and cost-effective if the limiting element is crimped and / or glued and / or welded and / or screwed to the additional fastening element. This measure can reduce the manufacturing costs for the support system and make assembly easier for the worker. Crimping the fastening element to the additional fastening element can ensure a robust and secure connection that can withstand high forces when the worker hammers the additional fastening element into the ground. Crimping the fastening element to the additional fastening element can be carried out cost-effectively directly during the manufacture of the additional fastening element. It is also conceivable for the crimping to take place at a later date, after the additional fastening element has been manufactured.This can be particularly useful if the support element and the additional fastening element have essentially identical structural design.

[0018] The construction of the support system can be very cost-effective and simple if the limiting element is designed as a hollow cylinder and has a larger outer diameter than the diameter of at least the second recess. This prevents the additional fastening element from penetrating the second recess. The hollow cylinder designed as a limiting element can also be crimped to the limiting element in a simple and cost-effective manner, in which case the geometric shape of the hollow cylinder can then change after crimping. The support system can be arranged very firmly and stably in the ground, in particular anchored, if the support element is arranged essentially vertically within the ground, with the additional fastening element being arranged at an angle beta of 5 to 45 degrees to the support element.It may be advantageous if the respective side planes of the pyramid-shaped floor connection element also have an angle of 5 to 45 degrees, in particular to the floor surface and / or to a base area of ​​the pyramid-shaped floor connection element.

[0019] Especially for very heavy photovoltaic modules, it can be very advantageous if the ground connection element comprises at least two, preferably four, second recesses, with an additional fastening element arranged in each second recess. This ensures a secure arrangement and connection of the support system to the ground and / or the ground surface.

[0020] According to a further preferred embodiment of the support system, it can be provided that the support element is non-positively and / or materially connected to a cutting element which is arranged at a distance from the ground connection element and, when the support system is assembled, is arranged within the ground. The cutting element can ensure easy insertion of the support element into the ground if objects, such as roots, are arranged at deeper levels of the ground, which can hinder easy insertion of the support system, in particular the support elements and / or the additional fastening elements, into the ground. Preferably, the additional fastening element should only be guided into the ground after the support element has been inserted into the ground, since objects and / or a more solid level of the ground and / or roots have already been broken down by the cutting element of the support element.The cutting element can be a significant advantage during the installation of the support system, particularly when additional fastening elements are used. The additional fastening elements should preferably not be provided with similar cutting elements, because they would then not be able to pass through the second recess due to the limited diameter of an already installed support system. Therefore, in the present support system according to the invention, the addition of the cutting element to the support element can be of great importance depending on the soil conditions. According to a further preferred embodiment of the support system, it should therefore also be provided that the end of the additional fastening element arranged within the soil is spaced apart and arranged above the cutting element in the installed state.

[0021] This advantageously ensures that the cutting element and / or the additional fastening element cannot damage each other during installation, particularly when driving the additional fastening element into the ground. Therefore, the distance between the ground surface and the cutting element should be greater than the distance between the end of the additional fastening element, which is preferably arranged within the ground, and the ground surface. Furthermore, it can be advantageous for crushing objects if the cutting element has sharp edges at its outer edge. It is also conceivable for the cutting element to be designed as a spiral ramp.

[0022] Alternatively, it is also possible for the support element to touch at least one, preferably all, additional fastening elements within the floor in order to further improve the stability of the support system.

[0023] The photovoltaic module can be stored simply, stably and safely if the respective storage element has a base section which is adjacent to the first storage section and / or second storage section, wherein the base section has a base fastening section which is designed for arranging the support element.

[0024] The energy generation can be significantly improved if the support system comprises at least the first and the second support element, wherein the distance of the bearing element of the first support element to the ground surface is longer than the distance of the bearing element of the second support element to the ground surface, wherein the first bearing section and the second bearing section of the bearing element of the first support element are arranged at an angle alphaf of greater than or equal to 180 degrees to one another and the first bearing section and the second bearing section of the bearing element of the second support element are arranged at an angle alpha2 of less than or equal to 180 degrees to one another.

[0025] The stability of the support system can be further improved if the support elements of the support system are at least partially connected to one another with at least one cross strut. The support system can be designed very cost-effectively if only the outer support elements of the support system are connected to one another by means of several cross struts. Furthermore, at least one cross strut connecting element can be arranged on the support element, which is connected to the support element in a force-fitting and / or form-fitting and / or butt-fitting manner. The cross strut connecting element can have an opening and / or recess designed to allow the passage of a fastening means, for example a pin or a screw, in order to connect the cross strut to the cross strut connecting element. The fastening means can be supported on the floor connecting element, in particular on the truncated pyramid.

[0026] The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show particularly preferred embodiments of the invention, but the invention is not limited thereto.

[0035] Figure 6a shows the support element, which is connected to a floor connection element, in which additional fastening elements are arranged, wherein the support element is provided with a cutting element in a side view, and

[0036] Figure 6b shows a side view of the support element, which is connected to a cross brace and to a floor connection element, in which additional fastening elements are arranged, wherein the support element is provided with a cutting element. Figure 1 shows a support system 1 according to the invention, which comprises several photovoltaic modules 3 and several support elements 4 designed as fastening elements, wherein the support elements 4 are arranged at a distance from one another and are each connected in a force-fitting and / or form-fitting manner to a floor surface 5 of a floor 2 and / or the floor 2, wherein the floor 2 is shown in a sectional view. The support elements 4 each have a floor connection element 6, preferably designed as a four-sided pyramid 8, which is preferably supported on the floor surface 5 (see Figure 1).Figure 2 shows a section of the support system 1 in more detail, with the structural design of the support system 1 being illustrated in more detail in Figure 2. The support system 1 here comprises four photovoltaic modules 3a-3d and nine floor connection elements 6, of which five floor connection elements 5a-8e can be seen in Figure 2, wherein the respective support element 4 is connected to at least one floor connection element 6 in a force-fitting and / or form-fitting and / or material-fitting manner. The floor surface 5 is not shown in more detail in Figure 2, but the respective floor connection element 6a-6e can rest on the floor surface 5 or, alternatively, can be arranged at least partially or completely within the floor 2, wherein the respective floor connection element 6a-5e has at least one first recess 14 for the passage of the support element 4.

[0037] Preferably, each support element 4 is assigned exactly one single floor connection element 6. Furthermore, the support system 1 in Figure 2 comprises nine support elements 4, of which

[0038] § of which seven support elements 4a-4f, 4h can be seen. Each of the nine support elements 4 is assigned a bearing element 7 for supporting the photovoltaic modules 3a-3d. In the present exemplary embodiment, for example, the distance of the bearing element 7d of the support element 4d to the floor surface 5 is longer than the distance of the bearing element 7c or 7e of the support element 4e or 4e to the floor surface 5, not shown in detail in Figure 2. This arrangement can also be designed analogously to the other support elements 4 and bearing elements 7 of the support system 1, so that, for example, a wave-shaped arrangement of the photovoltaic modules 3 is achieved, as can be seen in the side view of the support system 1 in Figure 1. Figure 3 shows a bearing element 7 which can be arranged, for example, in the carrier system 1, as shown, for example, in Figures 1 and 2.The bearing element 7 has a first bearing section 9, for example, for supporting the first photovoltaic module 3a and the second photovoltaic module 3b, and further has a second bearing section 10 for supporting the third photovoltaic module and the fourth photovoltaic module, which are not shown in detail in Figure 3. The respective photovoltaic module, in particular here the photovoltaic modules 3a, 3b, are each formed with a frame element 11a, 11b, each of which comprises a frame section 12a, 12b. In the present exemplary embodiment, the first bearing section 9 and the second bearing section 10 each comprise two stop elements 13a, 13b and 13c, 13d, respectively. The respective stop element 13a, 13b, 13c, 13d can, for example, be designed as a retaining lug which protrudes from the respective bearing section 9, 10 of the bearing element 7.

[0039] In Figure 3, only the two photovoltaic modules 3a, 3b are shown in simplified form. The first bearing section 9 shown in Figure 3 and the second bearing section 10 of the bearing element 7 of the carrier element 4 in question are arranged at an angle alpha2 of less than or equal to 180 degrees to one another. This corresponds, for example, to the bearing elements 7a, 7b, 7c, 7e, 7f, 7g shown in Figure 2. The first bearing section 9 and the second bearing section 10 of the bearing elements 7d, 7h, 7i (Figure 2) are arranged at an angle alpha1 of greater than or equal to 180 degrees to one another.

[0040] Furthermore, the bearing element 7 has a base section 15, which adjoins the first bearing section 9 and the second bearing section 10, wherein the base section 15 has a base fastening section 16, preferably designed as a circular or round-shaped hole, which is designed for the arrangement of the support element 4, which here, for example, has at least partially a corrugation on its outer side, which extends, for example, spirally on the support element 4. On the first bearing section 9 and the second bearing section 10, a clamp fastening section 17a, 17b is provided for the arrangement of a clamp element (not shown in detail), which, for example, connects at least the first photovoltaic module 3a and the second photovoltaic module 3b to one another in a force-fitting and / or form-fitting manner.Figures 4a and 4b show the support element 4 as it could be used, for example, in Figures 2 and 3. For the sake of simplicity, the corrugation on the outside of the support element 4, which extends, for example, spirally on the support element 4, has been omitted in the figures used here except for Figure 3. Therefore, the respective support element 4 of the support system 1 can have a smooth outer surface, depending on the given boundary conditions, or the support element 4 can have the corrugation on the outside according to the figure.

[0041] 3. Furthermore, the floor connecting element 6 has a first recess 14 for the passage of the support element 4. The floor connecting element 6 comprises four second recesses 18 spaced from the first recess 14 for the passage of an additional fastening element 19, wherein the respective additional fastening element 19 is positively and / or non-positively connected to the floor connecting element 6 and non-positively and / or positively connected to the floor surface 5 and / or the floor 2, as can be seen, for example, in Figures 5a, 5b and 6a, 6b, wherein the floor 2 is shown in a sectional view in Figures 5a, 5b and 5a, 6b. Furthermore, for reasons of simplified representation, as already described above, in Figures 5a, 5b and 6a, 6b, the corrugation on the outside of the support element 4 is omitted, which is, for example, spiral-shaped on the support element

[0042] 4. The support element 4 is arranged substantially vertically within the floor 2, wherein the respective additional fastening elements 19 are arranged at an angle Beta of

[0043] 5 to 45 degrees to the support element 4.

[0044] The floor connection element 6, which can be used for the support system 1, for example, is designed as a four-sided pyramid 8 comprising at least four side planes 20. The pyramid 8 has a truncated pyramid 21, which is designed to accommodate the first recess 14 and to pass through the support element 4, with at least one second recess 18 for the passage of the respective additional fastening element 19 being arranged in at least one side plane 20. The truncated pyramid 21 is designed as a hollow cylinder in the present embodiment. Alternatively, the truncated pyramid 21 can be configured merely as a simple opening, which is designed as a first recess 14. Furthermore, a limiting element 22 can be provided for each additional fastening element 19, which is connected to the respective additional fastening element 19 in a materially bonded and / or form-fitting and / or force-fitting manner.Furthermore, the respective limiting element 22 can be crimped and / or glued and / or welded and / or screwed to the respective additional fastening element 19. The limiting element 22, which is preferably fastened to the additional fastening element 19, cannot, particularly in the assembled state, be passed through the first recess 14 and / or the second recess 18. The limiting element 22 can be designed as a hollow cylinder and have a larger outer diameter than the diameter of the at least second recess 1§.

[0045] As can be clearly seen, for example, in Figures 5a, 5b, 6a, 6b, the respective additional fastening elements 19 are pointed at their respective ends, which are arranged within the base 2. Figures 5a and 6b further show that the support element 4 is non-positively and / or materially connected to a cutting element 23, which is arranged at a distance from the base connection element 6 and, in the assembled state of the support system 1, is arranged within the base 2. The end arranged within the base 2, in particular the pointed end of the additional fastening element 19, is spaced apart in the assembled state and arranged above the cutting element 23.The distance between the floor surface 5 and the cutting element 23 should be larger than the distance between the, in particular pointed, end of the additional fastening element 19, which is arranged within the floor 2, and the floor surface 5.

[0046] The support elements 4 of the support system 1 can be at least partially connected to one another by at least one cross strut 24, 24a, 24b. In Figures 4b, 5b, and 6b, the respective support element 4 of the support system 1 is connected to at least one cross strut 24, 24a, 24b. As can be clearly seen in Figures 4b, 5b, and 6b, preferably several cross strut connecting elements 25, 25a, 25b can be arranged on the respective support element 4, which are connected to the support element 4 in a force-fitting and / or form-fitting and / or material-fitting manner. The respective cross strut connecting elements 25, 25a, 25b each have an opening 26, 26a, 26b, which is designed for the passage of fastening means not shown in detail, for example pins and / or screws, in order to connect the respective cross strut 24, 24a, 24b with the respective cross strut connecting element 25, 26a, 25b.

[0047] The configurations of the support system 1 and its components shown in the figures, in particular different configurations of the support elements 4, can be combined with one another in a convenient manner. In particular, the ribbing shown in Figure 3 on the outside of the support element 4, which extends, for example, spirally on the support element 4, can be provided for at least one support element 4 of the support system 1, preferably for all support elements 4 of the support system 1. The ribbing can also be arranged on the additional fastening element 19. It is also conceivable for the support element 4 to touch at least one, preferably all, additional fastening elements 19 within the base 2.
