Description

Background of the invention

[0001] The invention relates to a manufacturing method for a foundation. The invention also relates to an assembly method for a solar module roofing with a foundation. The invention further relates to a solar module roofing.

[0002] The use of solar modules, such as photovoltaic modules or collector modules, is becoming increasingly important in the construction of roofing structures. The solar modules are typically used to create a roof surface that serves as a shelter for equipment, people, and / or vehicles. This can provide weather protection for the equipment, people, and / or vehicles while simultaneously generating heat and / or electricity through the solar modules.

[0003] However, with the expanded use of solar modules for roof construction, the requirements for the overall construction are increasing.

[0004] This increases the demands placed on the weather resistance and weatherproofness of such roofs. Even small roofs with a small roof area can be exposed to high wind loads, which must be taken into account in the design. Larger roofs, such as parking lots, which are usually built unprotected in open spaces, are often exposed to extreme wind loads. To prevent damage or destruction to the roof, which could endanger objects, vehicles, and people underneath, large foundations are constructed to anchor the roofs, in addition to the construction of high-strength support systems. However, this significantly increases the costs of such roofs. Object of the invention

[0005] It is an object of the invention to provide a solar module roofing that can withstand high loads and at the same time can be erected cost-effectively and quickly at a destination. Description of the invention

[0006] This object is achieved according to the invention by a manufacturing method for a foundation having the features of patent claim 1. The object is also achieved by an assembly method having the features of patent claim 5. The object is further achieved by a solar module roofing having the features of patent claim 7. The subclaims represent preferred embodiments of the invention.

[0007] The invention provides a manufacturing method. This manufacturing method is especially suitable for creating a foundation for a solar module roof.

[0008] A roof can be understood as a device with a roof surface spaced from a ground surface, which allows the shelter of equipment, persons and / or vehicles for protection against weather conditions and / or solar radiation.

[0009] The term "subsoil" can refer to the natural or artificial soil or ground in which the foundation is constructed. The subsoil provides the basis for the foundation and significantly influences the stability and load-bearing capacity of the foundation and any solar module roofing erected on it. The subsoil can include a surface reinforcement or an artificially created surface, such as asphalt or concrete.

[0010] According to the invention, the manufacturing process comprises at least the following process steps: Step a) of the method involves forming a foundation recess in the subsurface of the solar module system. In other words, this step describes the process by which a suitable depression is created in the ground. This depression serves to accommodate the foundation structure and must typically be dimensioned and shaped such that the foundation can be formed within it according to the technical requirements of the solar module system.

[0011] A foundation recess is typically an excavated area in the ground intended to accommodate the foundation of a building or, in this case, a solar module system. The size and shape of the recess is typically tailored to the requirements placed on the foundation. For example, the size of the foundation increases with the size of the roof area of ​​the solar module roof. Furthermore, the size of an individual foundation can decrease with the increasing number of foundations created for a solar module roof. Furthermore, for example, a foundation depth can exceed the usual frost line in the subsoil at the foundation construction site and / or be adapted to the nature of the subsoil.

[0012] A further method step b) involves inserting at least one ramming profile into the subsoil beneath the foundation recess. Preferably, two or more ramming profiles are inserted into a single foundation recess. This can further increase the strength of the foundation.

[0013] According to the invention, the piling profile is inserted into the subsoil via the already formed foundation recess. Furthermore, the piling profile is inserted into the subsoil of the foundation recess in such a way that the piling profile protrudes from the subsoil into the foundation recess. In other words, the piling profile is not fully inserted into the subsoil, leaving a non-inserted protrusion in the foundation recess. This enables the piling profiles to be particularly securely and firmly embedded in the foundation. This creates a strong connection between the foundation and the subsoil, improving the structural safety and durability of the entire system.

[0014] The at least one piling profile is typically driven into the ground using a piling mechanism. This allows the piling profiles to be firmly anchored in the subsoil without prior removal of additional excavated material.

[0015] To enable the piling profile to be inserted deeply into the subsoil and the foundation excavation, a piling extension can be used. The piling extension can be temporarily attached to the piling profile to facilitate driving. This allows conventional piling mechanisms to be used, simplifying and reducing the cost of creating the foundation.

[0016] A ramming profile can be understood as an elongated element, usually made of metal, which is permanently driven into the ground to form and / or strengthen the foundation.

[0017] A further process step f) involves at least partially filling the foundation recess with concrete. In other words, the foundation recess is filled with concrete, although it does not necessarily have to be completely filled. The concrete encloses the ramming profile protruding into the foundation recess and hardens into a solid block that serves as a stable foundation for the solar module system.

[0018] According to the invention, concrete is to be understood as a building material which is produced by hardening a mixture of aggregates, water and a binding agent, in particular cement.

[0019] The at least one ramming profile preferably has a C-shaped profile cross-section. The ramming profile is particularly preferably designed as a hat profile. Alternatively or additionally, ramming profiles with other profiles can be used. However, a C-shaped profile cross-section or a hat profile has proven particularly suitable for easier driving into the subsoil. Furthermore, such a profile cross-section has a large contact area with the concrete, thereby increasing the hold in the concrete block.

[0020] The length of the piling profile can be adapted to the requirements of the foundation. In other words, the driving depth and thus the anchoring can be easily adjusted as needed. This allows the foundation excavation to remain unchanged, reducing planning and construction costs.

[0021] In summary, the invention proposes a manufacturing method for a foundation which, in addition to forming a concrete block, provides for the driving of one or more ramming profiles into the subsoil. The ramming profiles are initially anchored independently in the subsoil and, upon completion of the manufacturing process, are permanently bonded to the concrete block. The finished foundation thus comprises a combination of concrete foundation and ramming profile. By using at least one ramming profile, a deep anchoring of the foundation in the subsoil can be created without the need for a complex, deep foundation recess. In addition, the stability and resistance to loads occurring on the foundation is considerably increased. In addition, the concrete foundation can be produced using a smaller amount of concrete, which further reduces material costs and the costs for excavating the foundation recess.

[0022] The manufacturing method according to the invention thus enables the formation of high-strength and cost-effective foundations that can withstand the static and dynamic loads of solar module roofs and thus extend the life cycle and maintenance intervals of solar module roofs.

[0023] In a preferred embodiment, the manufacturing method comprises the additional method step c), which involves lining the foundation recess with a foundation textile. A foundation textile typically represents a foundation formwork to prevent concrete from flowing out of the foundation recess until the concrete hardens or sets. A foundation textile represents a particularly cost-effective and safe way of lining the foundation recess. The foundation textile can be manufactured inexpensively and transported to the foundation production site. Furthermore, the foundation textile is particularly flexible in adapting to structural conditions. For example, the foundation textile can be adapted to the foundation recess by cutting or folding.

[0024] The lining of the foundation recess can be carried out before or after the insertion of at least one ramming profile.

[0025] The foundation textile is preferably formed in one piece. Alternatively or additionally, the foundation textile is preferably designed to line the foundation recess wall, in particular the entire wall, and / or the foundation recess base. Particularly preferably, the foundation textile is designed in a sack-like manner and adapted to the shape of the foundation recess. The foundation textile can, for example, be cuboid-shaped.

[0026] In a further preferred embodiment, the manufacturing method comprises the additional method step d), which provides for the arrangement of reinforcing bars in the foundation recess. The reinforcing bars are arranged in the foundation recess, in particular as a reinforcing cage or in the form of several reinforcing cages. Reinforcing cages can be manufactured in preparation for the manufacturing process and shorten the duration of the manufacturing process at the foundation construction site. The introduction or arrangement of reinforcing bars in the foundation recess further increases the stability of the foundation. Furthermore, when reinforcing bars are used, an eccentric load on the foundation can be absorbed particularly reliably by the foundation. This allows the foundation to be flexibly adapted to structural conditions and / or tolerances.

[0027] Preferably, the reinforcement bar is arranged around the projection of the at least one ramming profile protruding into the foundation recess. In other words, the at least one ramming profile can, in particular, protrude into the reinforcing bar arranged in the foundation recess. This can achieve a particularly high strength and bond between the ramming profile and the concrete, which has a favorable effect on the loads that the foundation can absorb.

[0028] A further preferred embodiment of the manufacturing method provides the additional method step e), in which at least one support post of a support system of the solar module roof is partially arranged in the foundation recess. In other words, a portion of the support system is arranged in the foundation recess before the foundation is completed and subsequently enclosed by the concrete. This allows the support system to be attached to the foundation in a particularly resilient manner.

[0029] A mounting bracket can be used to position and / or align the support post in the foundation recess.

[0030] The mounting bracket is suitable and designed for aligning the support system, in particular the support post. The mounting bracket preferably has a bracket base for supporting or distributing loads. The bracket base is preferably designed to project beyond a foundation recess. In other words, the bracket base rests on an edge of the foundation recess.

[0031] The console base is preferably U-shaped or designed in the form of a rectangular frame. This allows the console base, and thus the entire mounting bracket, to be robust and lightweight.

[0032] The mounting bracket preferably has a holding device for holding the support system, in particular the support post. The holding device is typically designed to hold the support system in a predetermined position. The holding device serves to releasably fasten the support system for assembly purposes and can subsequently be detached from the support system. Typically, the holding device is designed to clamp the support system or the support post.

[0033] Alternatively or additionally, the mounting bracket can have a height adjustment mechanism designed to adjust the distance between the holding device and the bracket base. This allows for particularly flexible adjustment of the mounting position of the support system or support post and / or the holding position of the holding device on the support system or support post. The height adjustment mechanism can have threaded rods that enable the entire height adjustment and / or tilting of the mounting bracket.

[0034] Using the mounting bracket, the position of the support system or support post can be aligned with the foundation. Any tolerances can be compensated for during foundation construction, allowing the solar module roof to be installed without any further adjustments. This simplifies and speeds up the installation of the solar module roof.

[0035] The mounting bracket described above and below and shown in the figures represents an independent inventive aspect and as such can exist independently of the described features of the manufacturing method, the assembly method and the solar module roofing.

[0036] In particular, a mounting bracket with a bracket base for arranging the mounting bracket at an edge of a depression in the ground, in particular a foundation recess, and a holding device for aligning an elongated profile structure, in particular a support post, represents a separate aspect of the invention. The aspect of the invention can be combined with the expedient features of the manufacturing method, the assembly method and / or the solar module roofing described above and below.

[0037] The underlying invention is also solved by an assembly method.

[0038] The assembly method is designed and suitable for constructing a solar module roof. In particular, the solar module roof to be constructed comprises a support system and at least two solar modules. The solar module roof is preferably a solar module roof with two or more solar modules, as described above and below.

[0039] The assembly process includes at least the following assembly steps: An assembly step a) of the assembly method provides for the formation of at least one foundation. Typically, the assembly method provides for the formation of two or more, in particular a plurality of, foundations. The foundations are formed according to the manufacturing method for a foundation described above and below. A further assembly step b) of the assembly process involves mounting the support system to the foundation. In other words, the support system is attached to the foundation. The support system can be modular. This allows for particularly rapid construction and thus the cost-effective construction of large-area roofs, such as parking lot roofs. Furthermore, the assembly step can include the installation or fastening of the components described above and below, such as the insertion system, of the support system.

[0040] In a particularly preferred embodiment of the assembly step, the support system is attached to the foundation during the construction of the foundation, according to the manufacturing process. This creates a particularly resilient connection between the support system and the foundation.

[0041] A further step in the assembly process involves mounting the solar modules to the support system. Mounting the solar modules typically involves forming the roof surface of the solar module canopy. This eliminates the need for additional roofing.

[0042] In a preferred embodiment of the mounting method, the solar modules are mounted by sliding them into a slide-in system formed on the support system. This allows for particularly quick and secure fastening. Furthermore, a slide-in system increases the stability of the solar module roofing.

[0043] The underlying task is further solved by a solar module roof.

[0044] The solar module roofing is suitable for creating freestanding shelters, especially vehicle shelters. In other words, the solar module roofing is suitable for creating large-area, continuous roofing. Furthermore, the solar module roofing is particularly robust and specifically designed for the freestanding construction of shelters.

[0045] The solar module roofing has at least one foundation. Typically, the solar module roofing comprises two or more, in particular a plurality of, foundations. The at least one, in particular each, foundation is designed or constructed according to a manufacturing method described above and below. This allows the solar module roofing to be particularly resilient and robust.

[0046] The solar module roofing also has a support system arranged on the at least one foundation. The support system serves to create a gap between the ground and the roof of the solar module roofing, thereby providing a covered area for sheltering equipment, people, and / or vehicles. Typically, the distance between the roof and the ground is more than two meters, preferably more than three meters, and particularly preferably more than four meters. The support system preferably forms a support frame for the solar modules.

[0047] The solar module roof comprises at least two solar modules. Typically, the solar module roof comprises two or more, in particular a plurality of, solar modules. The solar modules are attached directly and / or indirectly to the support system.

[0048] A solar module can be understood above and below as a photovoltaic module and / or a collector module, or a solar thermal module. The size and / or performance characteristics of solar modules can vary.

[0049] The at least two solar modules form at least part of the roof of the solar module canopy. In other words, the solar modules serve a dual function. On the one hand, the solar modules serve to generate electricity and / or heat, and on the other hand, they provide a weather-protected shelter.

[0050] In a preferred embodiment of the solar module roofing, the support system comprises at least one vertical support post, a cross member, and at least two longitudinal members attached to the cross member for arranging the solar modules. The support post is attached to the foundation at a first post end and to the cross member at a second, or free, post end. The components of the support system are attached to one another essentially perpendicularly and form a support frame for the solar modules that is spaced from the ground. The solar module roofing can thus be installed in a module-oriented or modular manner, which significantly shortens assembly times.

[0051] In a preferred embodiment of the solar module roof, the roof is designed as a butterfly roof or a pent roof. Both roof types offer a particularly favorable ratio between the roof area and the required number of support posts. This allows for a large roof area for electricity or heat generation, as well as for weather-protected shelter, with a small number of support posts. Furthermore, these roof types can drain liquids via a central drainage system, further reducing costs.

[0052] In a preferred embodiment of the solar module roofing, the support system comprises a slide-in system attached to the longitudinal beams. The slide-in system is designed for arranging the solar modules on the support structure by sliding them into the slide-in system. By sliding the solar modules into the system, a particularly quick and secure arrangement of the solar modules on the support system can be ensured. Furthermore, a slide-in system can increase the tightness of the roof surface and reduce the amount of water penetrating between the solar modules. This allows for a sheltered area to be designed with even greater weather protection.

[0053] A further preferred embodiment of the solar module roofing system is one in which the insertion system comprises at least two insertion profiles arranged parallel to one another. The insertion profiles can be designed as extruded profiles. The insertion profiles are preferably hollow, which allows for a reduction in material, weight, and costs.

[0054] Typically, the insertion system comprises several, particularly a large number of, insertion profiles. This allows for the insertion or arrangement of a large number of solar modules, thereby increasing the roof area and the utilization rate of the solar module roof.

[0055] The insertion profiles each have at least one guide section for guiding the solar modules. The guide sections typically form a holding frame for holding the solar modules. In other words, the guide sections encompass the solar modules on at least two opposite sides. Furthermore, the guide sections preferably overlap an edge area of ​​the solar modules not used by the solar modules for power and / or heat generation. This allows for particularly secure holding and further enhances the sealing against liquids.

[0056] In a particularly preferred embodiment of the solar module roofing, at least two opposing guide sections of two adjacent insertion profiles have a substantially U-shaped profile cross-section. In other words, two adjacent insertion profiles with the guide sections form an insert that encompasses the solar modules arranged at the front and rear. This can further improve the retention of the solar modules.

[0057] A further preferred embodiment of the solar module roofing system is one in which the insertion profiles have a drainage section formed below the guide section for draining liquid. In other words, the drainage section is formed vertically below the guide section when the insertion profile is arranged. The drainage section typically borders the guide section. The drainage section is essentially channel-shaped. In other words, the drainage section is only open at the top.

[0058] A further preferred embodiment of the solar module roofing system is one in which the at least two solar modules are arranged one behind the other between the insertion profiles in the guide sections of the insertion profiles. According to the embodiment, a sealing profile is arranged between the solar modules, forming a collecting section for collecting and draining seepage water. The collecting section opens into the drainage section of at least one of the insertion profiles. Preferably, a sealing profile designed to collect seepage water is arranged between all solar modules inserted one behind the other, between two insertion profiles.

[0059] The sealing profile preferably has a head section designed to rest on a front side of the solar modules, or on a side facing away from the covered area. The head section preferably forms a sealing contact with the solar modules, thus preventing liquid from penetrating between the solar modules.

[0060] The sealing profile preferably has a neck section arranged between the solar modules. The neck section can be designed as a spacer between the solar modules. Typically, the neck section lies tightly against the adjacent solar modules. The neck section can have one or more sealing lamellas that prevent further penetration of liquid. This can prevent liquid from seeping through between the solar modules.

[0061] The sealing profile particularly preferably includes a collecting section. The collecting section is typically designed to rest on the underside of the solar modules. Leaking liquid can be collected via the collecting section and prevented from dripping into the shelter area. The collecting section is typically designed to drain liquids into a corresponding drainage system.

[0062] The sealing profile is preferably formed in one piece. Particularly preferably, the sealing profile is made of an elastomer, particularly a UV-resistant one. This allows a particularly long-lasting sealing effect.

[0063] As solar panel roofs grow larger, significant amounts of liquid, particularly rainwater, must be drained away from the solar panel roofs. This results in significant water seepage, particularly in the area where the solar panels are mounted and at the points where they meet, into the solar panel shelter. Water penetrating the roof can cause water damage to objects and vehicles underneath, which must be prevented.

[0064] The use of a sealing profile and / or a slide-in system described above and below meets the requirements imposed by the extended use of roofs as weather-protected shelters for objects, people, and / or vehicles. The described sealing profile and / or the slide-in system thus meets the requirements for extended protection.

[0065] The insertion system described above and below and shown in the figures represents an independent inventive aspect and as such can exist independently of the described features of the manufacturing method, the assembly method and the solar module roofing.

[0066] In particular, a slide-in system with at least two parallel slide-in profiles for arranging solar modules, wherein the slide-in profiles each have at least one guide section on facing sides, represents a separate aspect of the invention. This aspect of the invention can be combined with the expedient features of the manufacturing method, the assembly method, the sealing profile, and / or the solar module roof described above and below. Particularly preferably, the slide-in system comprises a sealing profile as described above and below.

[0067] The sealing profile described above and below and shown in the figures represents an independent inventive aspect and as such can exist independently of the described features of the manufacturing method, the assembly method and the solar module roofing.

[0068] In particular, a sealing profile for arrangement between two solar modules, comprising a head section designed for sealing engagement with the upper side of the solar modules, a neck section designed for sealing arrangement between the solar modules, and a collecting section designed for collecting seepage water below the solar modules, represents a separate aspect of the invention. This aspect of the invention can be combined with the expedient features of the manufacturing method, the assembly method, the insertion system, and / or the solar module roof described above and below. The sealing profile is particularly preferably designed for use in the insertion system described above and below.

[0069] Further advantages of the invention will become apparent from the description, the claims, and the drawings. Likewise, the above-mentioned and further-described features can be used individually or in combination in any suitable manner. The embodiments shown and described are not intended to be exhaustive, but rather are exemplary in nature for describing the invention.

[0070] The manufacturing process 10 is for creating a foundation 12 (see Fig. 3, Fig. 8) is suitable and designed. In particular, the manufacturing method 10 is for creating and forming a foundation 12 for a solar module roofing 14 (see Fig. 3, 10-12) suitable and trained.

[0071] Typically, the manufacturing method 10 is suitable and designed for forming several, in particular a plurality of, foundations 12. In particular, the manufacturing method 10 is suitable for forming foundations 12 for large-area solar module roofing 14, for example, solar power lines and / or parking shelters.

[0072] The manufacturing process 10 comprises at least the following process steps: In a first method step 16 of the manufacturing method 10, the formation of a foundation recess 18 (see Fig. 4-8) in a subsurface 20 (see Fig. 3-8) of the solar module roof 14.

[0073] The formation of the foundation recess 18 may involve the removal or excavation of excavation 22 (see Fig. 4-8), for example, soil, gravel and / or stone. This list is not intended to be exhaustive. In addition, the formation of the foundation recess 18 may require the cutting of an existing surface reinforcement 24 (see Fig. 4-8), for example a concrete and / or asphalt surface.

[0074] The creation of the foundation recess 18 is typically carried out using commonly known tools. For example, but not limited to, cutting and / or excavation tools and / or machines may be used.

[0075] The foundation dimensions, in particular a foundation depth of 26 (see Fig. 4), a foundation width of 28 (see Fig. 4) and / or a foundation length of 30 (see Fig. 4) are preferably adapted to the solar module roofing 14 to be constructed. In particular, the foundation dimensions are adapted or coordinated to the expected load on the foundation 12 from the installed solar module monitoring system 14.

[0076] A further method step 32 of the manufacturing method 10 provides for the introduction of at least one ramming profile 34 (see Fig. 3, 5-8) into the subsurface 20. Typically, at least two ramming profiles 34 are introduced into the subsurface 20. According to the invention, the at least one ramming profile 34 is introduced into the subsurface 20 via the created foundation recess 18.

[0077] The insertion of the ramming profile 34 is typically carried out up to a ramming depth of 36 (see Fig. 3, Fig. 5). The driving depth 36 is typically measured between the foundation recess 18 and the part of the driving profile 34 furthest from the foundation recess 18. The driving depth 36 may exceed the foundation depth 26. In a special embodiment, the driving depth 36 may be at least twice, in particular at least three times, the foundation depth 26.

[0078] According to the invention, the ramming depth 36 is less than a ramming profile length 38 (see Fig. 5) of the ramming profile 34. In other words, the ramming profile 34 is not fully inserted into the subsoil 20. The ramming profile 34 protrudes with a projection 40 (see Fig. 5) into the foundation recess 18. This ensures that the ramming profile 34 is secured to the remaining foundation 12.

[0079] Typically, the insertion or ramming of the ramming profile 34 is carried out using suitable machines (not shown). For ramming the ramming profile 34, the use of a ramming extension 42 (see Fig. 5). The driving extension 42 is typically releasably attached to the driving profile 34 as an extension of the driving profile 34. After driving is complete, the driving extension 42 can be separated from the driving profile 34 and reused. The use of a driving extension 42 enables the use of conventional driving devices (not shown), thereby saving costs.

[0080] The ramming profile 34 can be inserted perpendicular to the surface fastening 24. This simplifies ramming. Furthermore, it can be provided that the ramming profile(s) 34 are inserted at an incline relative to the surface fastening 24. This allows the foundation strength to be optimized for a load caused by the solar module roofing 14. Furthermore, the at least one ramming profile 34 can be inserted into the subsurface 20 through a foundation recess base 44 or through a foundation recess wall 46. This allows the construction of the foundation 12 to be kept particularly flexible.

[0081] A further process step 48 of the manufacturing process 10 provides for at least partial filling of the foundation recess 18 with concrete 50 (see Fig. 3, Fig. 8). Typically, the foundation recess 18 is filled with the ramming profile 34 inserted. Further typically, the foundation recess 18 is filled with liquid concrete 50, which then sets to form a solid structure. After the concrete 50 sets or hardens, the foundation 12 is created and can be used, for example, to secure a solar module roof 14.

[0082] A possible process step 52 of the manufacturing process 10 involves lining or attaching a foundation formwork 54 (see Fig. 4). A foundation formwork 54 prevents the flow of concrete 50 when filling the foundation recess 18, whereby the required amount of concrete 50 can be minimized. The attachment of the foundation formwork 54 typically takes place after the removal or excavation of the foundation recess 18. The foundation formwork 32 can be created, for example, using formwork boards (not shown). Preferably, the formation of the foundation formwork 54 takes place by lining the foundation recess 18 with a foundation textile 56 (see Fig. 4).

[0083] A further possible process step 58 of the manufacturing process 10 involves arranging reinforcing bars 60 (see Fig. 6, Fig. 7) in the foundation recess 18. In particular, the arrangement of reinforcing bars 60 in the form of at least one reinforcement cage 62 (see Fig. 6, Fig. 7). By arranging reinforcing bars 60, the strength of the foundation 12 can be significantly increased and enables the off-center attachment of the solar module roof 14 to the foundation 12. This allows structural tolerances to be taken into account.

[0084] Typically, reinforcing bars 60 are arranged after the foundation recess 18 has been completely removed. Further preferably, reinforcing bars 60 are arranged after a possible lining of the foundation recess 18 with a foundation formwork 54.

[0085] More preferably, the arrangement of reinforcing iron 60 takes place after the introduction of the at least one ramming profile 34. Particularly preferably, the at least one ramming profile 34 projects into the reinforcing iron 60. This can result in a particularly high strength of the foundation 12.

[0086] In a particular embodiment, the manufacturing method 10 provides for a possible method step 64 in which a partial arrangement of at least one support post 66 (see Fig. 3, Fig. 7, Fig. 8, Fig. 11) from a carrier system 68 (see Fig. 3, Fig. 7, Fig. 8, Fig. 10, Fig. 11) of the solar module roofing 14 in the foundation recess 18. The arrangement typically occurs before the foundation recess 18 is filled with concrete 50. In other words, the support post 66 is arranged in the foundation recess 18 before filling and is then enclosed by the concrete 50 used to fill the foundation recess 18. This allows for a particularly strong attachment of the support system 68 to the foundation 12 after the concrete 50 has set.

[0087] For arranging the support post 66 in the manufacturing recess 18, it can be provided that a mounting bracket 70 described above and below (see Fig. 7, Fig. 9). This ensures that the support post 66 is fixed in a predetermined position and orientation within the manufacturing recess 18 until the concrete 50 hardens.

[0088] Fig. 2 schematically shows an assembly method 72 according to the invention.

[0089] The assembly method 72 is for creating a solar module roof 14 (see Fig. 3, 10-12). The solar module roofing 14 typically comprises at least one foundation 12 (see Fig. 3, Fig. 8), a carrier system 68 (see Fig. 3, Fig. 10, Fig. 11) and at least two solar modules 74 (see Fig. 3, 10, 13-15).

[0090] In particular, the assembly method 72 is suitable for creating and forming a large-area solar module roof 14, for example a solar route and / or a parking shelter.

[0091] The assembly method 72 comprises at least the following assembly steps: A first assembly step 76 of the assembly method 72 provides for the formation of at least one foundation 12. According to the invention, the foundation 12 is produced according to the manufacturing method 10 described above and below (see Fig. 1). This allows for a particularly cost-effective yet high-strength foundation 12 to be provided.

[0092] Typically, multiple foundations 12 are constructed according to the manufacturing method 10 described above and below. This allows the assembly method 72 to be extended to larger solar module roofings 14.

[0093] A further assembly step 78 of the assembly method 72 provides for mounting the support system 68 on the foundation 12. The mounting of the support system 68 is typically carried out by attaching at least one support post 66 (see Fig. 3, Fig. 7, Fig. 8, Fig. 11) to at least one foundation 12. Furthermore, it can be provided that several support posts 66 are attached to several, in particular spatially spaced, foundations 12. The attachment can be achieved, for example, by screwing the support post(s) 66 to the respective foundation 12.

[0094] Preferably, the support post 66 is secured to the foundation 12 by arranging the support post 66 during the construction of the foundation 12. In this case, it can be provided that the support post 66 is arranged in the foundation recess 18 provided for forming the foundation 12 and is then cast with concrete 50. This allows the support post 66 to be secured particularly reliably.

[0095] Typically, mounting the support system 68 further includes attaching additional components of the support system 68 to the support post 66. In other words, the assembly method 72 may include mounting the support system 68 as such.

[0096] In a further assembly step 80 of the assembly method 72, the solar modules 74 are mounted on the support system 68. The solar modules 74 can be mounted on the support system 68 directly and / or indirectly. For example, the solar modules 74 can be attached to the support system 68 using retaining clips.

[0097] Typically, the mounting method 72 provides for the mounting of a plurality of solar modules 74, whereby large-area roofing can be formed.

[0098] In a preferred embodiment of the assembly method 72, the solar modules 74 are inserted into a slide-in system 82 formed or arranged on the carrier system 68 (see Fig. 3, 10-15) are mounted. Fig. 3 shows a solar module roof 14.

[0099] The solar module canopy 14 is suitable for forming freestanding shelters, in particular vehicle shelters. In other words, a roof 84 of the solar module canopy 14 is arranged at a canopy distance 86 from the ground 20, thereby enabling the sheltering and / or parking of objects (not shown), vehicles (not shown), and / or people (not shown).

[0100] The solar module roofing 14 comprises, as shown, several, here three, foundations 12. The foundations 12 are constructed according to the manufacturing method 10 for creating a foundation 12. In other words, the foundations 12 each have at least one ramming profile 34, here two ramming profiles 34, which are inserted vertically from the space occupied by the concrete 50 into the subsurface 20. In other words, the concrete portion of the foundation 12 is relieved by the anchoring effect of the ramming profiles 34. This can keep the load on the foundation 12 high and / or reduce the material consumption of concrete 50.

[0101] As shown, the foundations 12 can be arranged equally spaced from one another and arranged in a row. This can facilitate the installation of the solar module roofing 14 and reduce costs by using a larger proportion of system components.

[0102] According to the illustrated embodiment of the solar module roofing 14, a support system 68 is attached to the foundations 12 by means of several vertically arranged support posts 66. This allows the load to be distributed across several foundations 12 and the solar module roofing 14 to be scaled as needed. For reasons of clarity, only one support post 66 is identified by a reference numeral.

[0103] As shown, the support system 68 also comprises several, here three, cross beams 88, of which only two are shown in Fig. 3 are visible. The crossbeams 88 are attached to a free end 90 of the respective support post 66. For reasons of clarity, only one free end 90 of a support post 66 is provided with a reference symbol. In a vertical view from above of the solar module roof 14, the crossbeams 88 extend perpendicular to the arrangement of the foundations 12. This enables the formation of large-area roofs using fewer support posts 66 and thus increases the area available for parking below the roof 84.

[0104] The carrier system 68 comprises, as shown in Fig. 3 shows several, here six, longitudinal beams 92, which are attached to the cross beams 88 perpendicular to the cross beams 88. For reasons of clarity, only one longitudinal beam 92 is designated by a reference numeral. The longitudinal beams 92 enable the solar modules 74 to be arranged directly and / or indirectly on the support structure 68.

[0105] As shown, the solar modules 74 are arranged or attached to the support system 68 by means of a slide-in system 82 described previously and subsequently. The slide-in system 82 is attached to the longitudinal beams 92 of the support system 68 and is designed to arrange the solar modules 74 on the support system 68 by sliding them into the slide-in system 82.

[0106] The insertion system 82 has at least two insertion profiles 94 arranged parallel to one another for arranging the solar modules. As shown, the insertion system 82 has a plurality of insertion profiles 94, with two adjacent insertion profiles 94 each designed for inserting one or more solar modules 74 arranged one behind the other. For reasons of clarity, only two insertion profiles 94 are provided with a reference symbol.

[0107] The roof 84 can be formed by inserting the solar modules 74 between the insertion profiles 94. As shown, the roof 84 is completely covered by solar modules 74 after all solar modules 74 have been inserted.

[0108] According to the illustrated embodiment, the solar module roofing 14 has a roof 84 designed as a butterfly roof. This allows a single central drainage system 96 to be provided in the center of the roof 84 for drainage.

[0109] Fig. 4 shows a first manufacturing state 98 of a foundation 12 (see Fig. 3, Fig. 8) with a foundation recess 18 formed in the subsoil 20.

[0110] As shown, the foundation recess 18 is essentially cuboid-shaped, which means that the costs for excavating the foundation recess 18 can be kept low.

[0111] Further, as shown, the foundation recess 18 is lined with a foundation formwork 54. The foundation formwork 54 is designed as a foundation textile 56. A foundation textile 56 can be particularly advantageously unfolded from a folded state in the foundation recess 18. The formation of a complex foundation formwork 54 made of boards can be dispensed with. Furthermore, a foundation textile 56 has a low dead weight and can therefore be delivered inexpensively and quickly to a manufacturing site of the foundation 12.

[0112] The foundation formwork 54, in particular the foundation textile 56, can have one or more, here two, profile openings 100. The profile openings 100 can be used to facilitate the passage of the ramming profiles 34 (see Fig. 3, 5-8). This also prevents the foundation textile 56 from shifting or wrinkling when the ramming profiles 34 are inserted into the subsoil 20.

[0113] Fig. 5 shows a second manufacturing state 102 of the foundation 12 (see Fig. 3, Fig. 8) with ramming profiles 34 projecting into the foundation recess 18.

[0114] In other words, Fig. 5 a manufacturing state 102 with ramming profiles 34 inserted into the subsoil 20. The ramming profiles 34 are shown through the profile openings 100 (see Fig. 4) of the foundation textile 56 are inserted into the subsoil 20 to a ramming depth 36 and protrude with the overhang 40 into the foundation recess 18.

[0115] According to the illustrated state, the ramming extensions 42 are arranged on the ramming profiles 34.

[0116] The ramming profiles 34 can have a U-shaped or C-shaped cross-sectional profile. As shown, the ramming profiles 34 are designed as a hat profile. This facilitates the insertion or driving of the ramming profiles 34 and their embedding in the concrete 50.

[0117] Fig. 6 shows a third manufacturing state 104 of the foundation 12 (see Fig. 3, Fig. 8) with reinforcing bars 60 or a reinforcement cage 62 arranged in the foundation recess 18.

[0118] As shown, the two ramming profiles 34 extend into the foundation recess 18 and into the reinforcing bars 60. In other words, the reinforcing bars 60 surround the sections of the ramming profiles 34 to be enclosed by the concrete 50. This allows the strength of the foundation 12 to be further increased.

[0119] Fig. 7 shows a fourth manufacturing state 106 of the foundation 12 (see Fig. 3, Fig. 8) with support post 66 of the support system 68 arranged in the foundation recess 18.

[0120] In other words, Fig. 7 shows the manufacture of the foundation 12, in which a part of the support system 68, here the support post 66, is permanently attached to the foundation 12. Typically, the support post 66 is concreted in when filling the foundation recess 18.

[0121] As shown, it can be provided that a mounting bracket 70, described above and below, is used to fix the support post 66 in the foundation recess 18. Typically, the mounting bracket 70 is designed to be supported on the substrate 20 or on the surface fastening 24 next to the foundation recess 18 and projects beyond the foundation recess 18 in at least one direction of extent. Furthermore, the mounting bracket 70 is typically designed to hold and align the support post 66 in a predetermined position. In a preferred embodiment, the mounting bracket 70 is designed to hold the support post 66 until the concrete 60 hardens (see Fig. 3, Fig. 8) to be positioned floating in the foundation recess 18. This allows the support post 66 and thus the support system 68 to be positioned particularly precisely.

[0122] Fig. 8 shows a fifth manufacturing state 108 of the foundation 12 (see Fig. 3, Fig. 8) with a foundation recess 18 filled with concrete 50.

[0123] In other words, Fig. 8 a foundation 12 formed by the manufacturing process 10. The foundation recess 18 is, as shown, filled with concrete 50 essentially up to the surface fixing 24. The concrete 50 fixes the ramming profiles 34, the support post 66 and possible reinforcing bars 60 (see Fig. 6, Fig. 7) in their alignment to each other.

[0124] As shown, a surface renewal 110 of the surface reinforcement 24 may be provided. Typically, the surface renewal 110 is performed in a process step following the filling and curing of the concrete 50 in order to counteract damage to the surface reinforcement 24 resulting from shrinkage of the concrete 50.

[0125] Fig. 9 shows a mounting bracket 70 in a perspective view.

[0126] The mounting bracket 70 is used to align a support post 66 (see Fig. 3, Fig. 7, Fig. 8, Fig. 11) in a foundation recess 18 (see Fig. 4-8) suitable and trained.

[0127] The mounting bracket 70 may have a bracket base 112 for supporting the mounting bracket 70 on a base 20 (see Fig. 3-8) next to a foundation recess 18. The console base 112 is preferably at least U-shaped, in particular rectangular.

[0128] The mounting bracket 70 may further include a holding device 114 for holding the support post 66 (see Fig. 3, Fig. 7, Fig. 8, Fig. 11) in a predetermined orientation relative to the foundation recess 18. The holding device 114 is preferably designed to clamp the support post 66.

[0129] The mounting bracket 70 can also have a height adjustment 116 designed to adjust a distance between the holding device 114 and the bracket base 112. As shown, the height adjustment 116 can be achieved by threaded rods 118. For clarity, only one threaded rod 118 is provided with a reference symbol.

[0130] The height adjustment 116 can comprise two separately arranged adjustment profiles 120, each of which is arranged on the console base 112 via two threaded rods 118. This allows the inclination of the holding device 114 relative to the console base 112 to be adjusted. This allows for the compensation of an inclination of the subsurface 20 and thus the vertical arrangement of the support profile 66 on slight slopes.

[0131] Fig. 10 shows a partial section of the solar module roofing 14 from Fig. 3 with the insertion system 82 arranged on the support system 68.

[0132] The insertion system 82 comprises, as shown, a plurality of insertion profiles 94, which are equally spaced and attached to the support system 68 in parallel. The insertion profiles 94 each have at least one guide section 122 for arranging a solar module 74 on the sides facing the adjacent insertion profiles 94. For reasons of clarity, only two guide sections 122 are provided with a reference numeral.

[0133] In other words, two adjacent insertion profiles 94 with the mutually facing guide sections 122 form a holding frame 124 into which at least one solar module 74 can be inserted along the guide sections 122.

[0134] The guide sections 122 can have a substantially U-shaped profile cross-section. This enables particularly secure guidance during insertion along the guide sections 122. Furthermore, movement perpendicular to the insertion direction can be effectively prevented, thereby simplifying the fixing of the solar modules 74.

[0135] As shown, the insertion system 82 of the solar module roofing 14 can provide for two solar modules 74 to be arranged one behind the other in the guide sections 122 of two adjacent insertion profiles 94. Preferably, the insertion system 82 has a sealing profile 126 arranged between the solar modules 74.

[0136] Fig. 11 shows a further section of the solar module roofing 14 from Fig. 3.

[0137] The insertion profiles 94 of the insertion system 82 can have a drainage section 128 formed below the guide section 122 for draining liquid, in particular rainwater. The drainage section 128 is preferably substantially channel-shaped, with drainage taking place along a profile extension 130 of the respective insertion profile 94. For reasons of clarity, only one guide section 122, one drainage section 128, and one profile extension 130 are provided with a reference symbol.

[0138] The insertion profiles 94 preferably have an inclination that ensures a controlled drainage of liquids via the drainage sections 128 in a predetermined direction. Typically, the drainage sections 128 of the insertion profiles 94 open into a main drainage channel 132 of the support system 68 or the solar module roofing 14. The main drainage channel 132 can be connected to a downpipe 134. This ensures a controlled drainage of the liquids onto the roof 84 (see Fig. 3) the solar module roofing 14 is protected from liquids, especially rainwater.

[0139] Fig. 12 shows a detailed view of the drainage sections 128 of the insertion profiles 94 leading into the main drainage channel 132 of the solar module roofing 14 Fig. 11.

[0140] The solar modules 74 (see Fig. 3, 10, 13-15) can be collected via the drainage sections 128 and drained in the direction of the profile extension 130. The liquids are initially transferred from the respective drainage section 128 into the main drainage channel 132 along the exemplary drainage path 136 and from there drained via the downpipe 134.

[0141] Fig. 13 shows a partial section of the insertion system 82 of the solar module roofing 14 from Fig. 10 with the sealing profile 126 arranged on an insertion profile 94.

[0142] As shown, the sealing profile 126 can form a collecting section 138 for collecting and draining seepage water. Preferably, the collecting section 138 opens into the drainage section 128 of the insertion profile 94. The drainage of the seepage water can be carried out according to an exemplary drainage path 140, after which the seepage water, after flowing into the drainage section 128, is drained along the profile extension 130.

[0143] Fig. 14 shows a partial sectional view of the insertion system 82 from Fig. 10 with the sealing profile 126 arranged between the solar modules 74.

[0144] The sealing profile 126 has a head section 142 for engagement with a top side of the solar modules 74. The head section 142 reduces the penetration of seepage water between the solar modules 74.

[0145] Furthermore, the sealing profile 126 has a neck portion 144 arranged between the solar modules 74. The neck portion 144 can comprise one or more sealing lamellas 146, which, when the sealing profile 126 is arranged between the solar modules 74, rest against the end faces of the adjacent solar modules 74. This can further reduce the penetration of seepage water.

[0146] The sealing profile 126 can further include the collecting section 138. The collecting section 138 preferably rests against the undersides of the adjacent solar modules 74 in an arranged state. Particularly in the case of an angular offset between the adjacent solar modules 74, a leakage gap can occur at the head section 142 and the neck section 144, allowing seepage water to penetrate. Penetrating seepage water can be collected and drained away via the collecting section 138. This reliably prevents the seepage water from dripping into the covered area below the solar module roofing 14.

[0147] Fig. 15 shows a partial sectional view of the insertion system 82 onto an end section of an insertion profile 94.

[0148] The insertion system 82 may include a clamping block 148 that is arranged within the guide sections 122 to secure the solar modules 74. Typically, the clamping block 148 is inserted into the respective guide section 122 and brought into contact with the solar module 74.

[0149] A profile end 150 can then be arranged, in particular screwed, on the insertion profile 94.

[0150] Typically, the clamping block 148 and / or the profile end 150 are arranged at both profile ends of an insertion profile 94. This allows the solar modules 74 to be fixed particularly securely.

[0151] The clamping block 148 may include a mounting nipple 152, which enables particularly easy mounting of the clamping block 148. The mounting nipple 152 serves to hold the clamping block 148 when attaching the profile end cap 150. The mounting nipple 152 typically protrudes through an opening in the profile end cap 150 and can be gripped with a tool or by hand and held in position on the solar module 74 until the profile end cap 150 is secured.
