Description

[0001] Roof construction, first roof construction pair, construction extension and building system

[0002] The present invention relates to a roof structure comprising a substantially rectangular frame-shaped support unit and two support groups, a first roof structure pair comprising a roof structure according to the invention and a further roof structure according to the invention, a structural extension and a building system comprising at least one roof structure according to the invention and / or at least one first roof structure pair according to the invention.

[0003] Available land, particularly in densely populated areas like cities, must be used as efficiently as possible, especially with regard to creating opportunities for alternative energy sources, particularly photovoltaics or solar thermal energy. This can be achieved, for example, by installing photovoltaic or solar thermal systems on the roofs of covered areas, such as car parks. Ideally, the energy generated by these systems can be used directly to charge the batteries of electric vehicles.

[0004] Roof structures are known from the prior art that feature a multitude of support groups for carrying a carrier unit on which a photovoltaic or solar thermal system can be mounted. When these roof structures are combined into a building system, the space formed between the carrier unit and a mounting surface is hardly usable by cars due to the large number of support groups and their relative arrangement; overall, the use of space is inefficient. US 10,554,167 B2 discloses a carport with solar modules and an associated support structure, the latter being tiltable about a hinge fixed to the ground. This support structure has a substantially rectangular frame carrier unit, which in turn has two crossbeam elements and at least two longitudinal beam elements.Furthermore, the carport features two support groups designed as triangular components, each with a first and a second end section. The first end section, due to its connection to the joint, is also designed for attachment to a mounting surface in the usable position. The support groups have three struts extending between the end sections.

[0005] The present invention is therefore based on the objective of proposing an easy-to-manufacture and cost-effective roof construction which makes the space enclosed by the roof construction easily accessible and thus makes its use particularly versatile.

[0006] The problem is solved by a roof structure comprising a substantially rectangular frame-shaped support unit, itself having two crossbeam elements and at least two longitudinal beam elements, further comprising two support groups, wherein the two support groups each have a first end region and a second end region, wherein the first end regions of the two support groups are each designed for attachment to a mounting surface in the service position, wherein the second end region of a first support group is attached off-center to a first of the two crossbeam elements and the second end region of the second support group is attached off-center to the second of the two crossbeam elements, wherein each support group comprises at least two support columns extending between the first end region and the second end region.wherein all support columns of a support group are arranged eccentrically in the same direction from the respective centers of the first and second crossbeam elements, wherein a roof angle of less than or equal to 45° is formed between the mounting surface in the operating position and the first crossbeam element and between the mounting surface in the operating position and the second crossbeam element, wherein a total support angle is formed between the at least two support columns of a support group, wherein all total support angles are less than or equal to 40°.

[0007] The crossbeam and longitudinal beam elements of the support unit preferably have an identical cross-section, particularly in the form of a double-T. All crossbeam elements preferably have the same length, and all longitudinal beam elements preferably have the same length. The crossbeam and longitudinal beam elements are made of steel, particularly by continuous casting. The crossbeam elements have retaining plates between the indentations formed by the double-T beam shape, particularly for fastening the longitudinal beam elements. Furthermore, the two crossbeam elements have end plates at their respective ends that cover the double-T cross-section completely. The rectangular frame shape of the support unit is formed by the two crossbeam elements and by the outermost of the at least two longitudinal beam elements. The first and second end regions of the support groups are formed, in particular, by the support columns.Another advantageous variant is one in which a plate-shaped support plate is arranged at the second end of each support column, allowing it to be securely fastened, particularly by means of screw connections, to the respective crossbeam elements and a mounting surface during use. The support columns of a support group preferably each share a common support plate at their second end. The off-center arrangement of all support columns of the same support group, pointing in the same direction from the respective centers of the first and second crossbeam elements, allows for particularly good accessibility to a space at least partially enclosed by the roof structure.The support columns of a support group are preferably arranged in the first end region such that they touch each other and / or are spaced apart such that the distance between any two immediately adjacent support columns in the first end region is a maximum of 10 cm, preferably a maximum of 5 cm, and particularly preferably a maximum of 3 cm. The compact design of the support groups according to the invention advantageously provides a stable roof structure that simultaneously restricts access to a space arranged within the roof structure as little as possible. All support columns advantageously have an identical cross-section, so that they can be manufactured, in particular, by a continuous casting process and easily cut to the required lengths. In a particularly advantageous manner, the mounting surface in the operating position is formed by a foundation.Furthermore, it is advantageous if the second end sections are attached to the first and second crossbeam elements at the same off-center position. Accordingly, the second end section of the first support group is the same distance from a center point of the first crossbeam element as the second end section of the second support group is from a center point of the second crossbeam element. Moreover, the second end sections are each offset in the same direction from the respective centers of the first and second crossbeam elements. The roof structure is thus mirror-symmetrical with respect to the first and second transverse planes.

[0008] The invention thus represents an optimized combination of solar energy use and function as a building.

[0009] In an advantageous embodiment of the invention, each support group comprises at least three support columns extending between the first end region and the second end region, each column having a substantially vertically oriented vertical support and at least two transverse supports. A first support angle is formed between each of the transverse supports of a support group and the vertical support of the same support group, with all first support angles being less than or equal to 20°. The vertical support and the at least two transverse supports of each support group preferably each have a common support bearing in the second end region. The off-center arrangement, in conjunction with the design of one vertical support and at least two transverse supports, advantageously allows for extensive access to the space within the roof structure.The mounting surface in its operating position provides an alternative and equivalent reference point for defining the roof angle, as do the respective vertical supports of the first and second support groups. The vertical supports are oriented essentially perpendicular to the mounting surface in its operating position. The roof angle formed between the mounting surface in its operating position and the first crossbeam element, and between the mounting surface in its operating position and the second crossbeam element, is the complement of an angle formed between the vertical support of the first support group and the first crossbeam element, and between the vertical support of the second support group and the second crossbeam element. In a particularly advantageous embodiment, all first support angles are less than or equal to 10°, preferably less than or equal to 5°.The smaller the initial support angle between the vertical column and all transverse columns, the less the accessibility of the space / area beneath the roof structure is restricted. However, sufficient stability must always be ensured, even in storms and similar environmental conditions. Particularly advantageous initial support angles represent the best possible compromise between these requirements.

[0010] In an advantageous embodiment of the invention, the vertical support of the first support group lies in a common, substantially vertically oriented first transverse plane with the at least two transverse supports of the first support group, and the vertical support of the second support group lies in a common, substantially vertically oriented second transverse plane with the at least two transverse supports of the second support group, wherein the first transverse plane and the second transverse plane are oriented parallel to each other. Advantageously, bending forces arising from the load-bearing capacity of the support unit are thus absorbed by the first and second support groups. The vertical support is preferably arranged between the at least two transverse supports of each support group.

[0011] In a further development of the invention, it is provided that the two support groups each comprise at least one support column designed as a longitudinal support, wherein a second support angle is formed between all longitudinal supports of a support group and the vertical support of the same support group, wherein all second support angles are less than or equal to 20°, preferably less than or equal to 10°, and particularly preferably less than or equal to 5°. In a particularly advantageous embodiment, the support columns of a support group are arranged in the first end region such that they touch the immediately adjacent support column. The longitudinal supports ensure a further increase in the strength of the roof structure. Such a selected second support angle allows for minimal restriction of access to the space within the roof structure while maintaining sufficient stability of the entire roof structure.

[0012] In a particularly advantageous embodiment of the invention, the at least one longitudinal support and the vertical support of the same support group lie in a common, substantially vertically oriented, longitudinal plane; preferably, all longitudinal and vertical supports of the two support groups lie in a common, substantially vertically oriented, longitudinal plane, wherein the longitudinal plane is oriented orthogonally to the first and second transverse planes. The accessible space within the roof structure is reduced upwards by the design of the first and second support brackets. Depending on the height of the roof structure, this has no effect on the most common uses, such as walking or driving on the roof structure, but contributes significantly to the strength and stability of the roof structure itself.

[0013] In a further development of the invention, the support columns are provided with a cavity, wherein at least one of the cavities contains pipes and / or at least one of the cavities is designed as a downpipe and / or the roof structure includes a downpipe. The support columns are particularly advantageously designed as rectangular tubes. For the arrangement of pipes, in particular pipes of a solar or photovoltaic system mounted on the support unit, within at least one support column, a through-hole is provided in the first end region and / or in the second end region, so that the pipe can be inserted into the at least one support column or led out of it at the other end region without having to position the pipes in such a way that they can be easily damaged.In a particularly advantageous embodiment, the vertical support is designed as a downpipe, with through-holes advantageously provided in the upper and lower end regions of the vertical support to allow water to enter and exit. The through-hole in the upper end region is preferably connected to a drainage channel of the roof structure such that rainwater is transported from the drainage channel via the downpipe to the ground. In a further embodiment, the roof structure can include a downpipe next to the support columns, the downpipe preferably being a rectangular tube or a tube with a circular cross-section. The downpipe is advantageously arranged at an edge of the support unit closest to the first end region in order to utilize the advantages of the slope, preferably formed by the roof pitch, to easily and quickly transport the rainwater away.Furthermore, the downpipe is advantageously positioned as close as possible to one of the support groups, so that the area within the roof structure that cannot be driven on or walked on is minimized as much as possible.

[0014] In an advantageous embodiment of the invention, an end of the crossbeam elements located further away from the two support groups projects beyond a rectangle formed by the longitudinal beam elements and crossbeam elements. The longitudinal beams are positioned along the longitudinal plane between the crossbeams. The projection of the more distant end is particularly advantageous because it facilitates connection between the more distant ends of several adjacent roof structures by providing better access. It is especially advantageous if the longitudinal beam element located closer to the more distant end is set back by at least 1.5% of the length of the crossbeam element, preferably by at least 3%, and most preferably by at least 5%.

[0015] In a further development of the invention, it is provided that the two support groups each have at least one base plate, wherein at least the vertical support and at least two transverse supports are each attached to the base plate. The support columns are fully welded or bolted to the base plates, thus creating a reliable and durable connection. The base plate advantageously has at least two through holes by means of which the roof structure can be connected to a mounting surface, for example, by screws or bolts, when in use. The base plate is designed such that it covers as small an area as possible of the mounting surface in a usable position, so that the drivable and walkable space within the roof structure is not restricted.Advantageously, the at least one longitudinal support of a support group is attached to the same base plate as the vertical support and the at least two transverse supports in the first end area. Alternatively, the at least one longitudinal support of a support group can be attached to a separate base plate, which is advantageously positioned directly adjacent to the base plate on which the vertical support and the at least two transverse supports are attached. Depending on the design of the roof structure and the need for additional strength from the at least one longitudinal support, this support can be added modularly. The separate base plate of the longitudinal support is functionally and structurally identical to the base plate on which the vertical support and the at least two transverse supports are formed. All base plates are positioned in the first end area.An advantageous embodiment of the invention provides that the support unit comprises stiffening elements, wherein the stiffening elements comprise round steel elements. The stiffening elements advantageously have smaller dimensions than the crossbeam and longitudinal beam elements, so that the weight of the support unit is minimized by the stiffening elements, while its strength is increased as much as possible. The stiffening elements, in particular the round steel elements, are advantageously arranged parallel to the first and second transverse planes or at an angle to the first and second transverse planes and lie in a common plane with the crossbeam and longitudinal beam elements. In a particularly advantageous manner, the crossbeam elements, longitudinal beam elements, and stiffening elements form a truss structure to provide the most stable support unit possible.The stiffening elements advantageously comprise, in addition to the round steel elements, fixing elements which are welded or bolted to a crossbeam element or a longitudinal beam element and, in particular, are welded or bolted to the round steel elements. In a particularly advantageous embodiment, the stiffening elements, especially the round steel elements, have tensioning elements by means of which the absolute length of the stiffening elements can be adjusted, so that, for example, in summer and at warmer temperatures, when the material expands, or in winter and at colder temperatures, when the material contracts, the length can be adjusted such that the stress between stiffening elements, crossbeam elements, and longitudinal beam elements is always essentially constant.

[0016] In a further development of the invention, the support unit comprises at least one trapezoidal sheet and / or connecting sheet profiles. The at least one trapezoidal sheet is preferably oriented such that a trapezoidal cross-section of the at least one trapezoidal sheet is parallel to the longitudinal plane, so that, for example, rainwater falling on the roof structure flows off via gutters formed by the trapezoidal sheet. The roof pitch preferably forms a slope, thus enhancing the drainage of rainwater through the gutters. The trapezoidal sheet is advantageously connected to at least one crossbeam element and / or at least one longitudinal beam element by means of a force-fit connection, in particular via a screw connection. The trapezoidal sheet rests against the at least one crossbeam element and / or at least one longitudinal beam element on a side of the crossbeam elements and longitudinal beam elements opposite the support groups.The at least one trapezoidal sheet thus covers the crossbeams, longitudinal beams, and support assemblies of the roof structure, protecting them from rain, snow, and other environmental influences. The connecting sheet profiles are advantageously L-shaped, U-shaped, or V-shaped, so that they incorporate an outer edge of the at least one trapezoidal sheet and protect users and other objects from injury or damage caused by an edge of the at least one trapezoidal sheet. The connecting sheet profiles are preferably force-fit, in particular via screw connections, to the trapezoidal sheet or to the trapezoidal sheet and at least one crossbeam and / or at least one longitudinal beam. In a plan view, the connecting sheet profiles form the outer edge of the support element and thus of the roof structure.

[0017] The present problem is further solved by a first pair of roof structures comprising a roof structure according to the invention, wherein a further roof structure according to the invention is arranged parallel to a longitudinal plane of the roof structure and mirror-symmetrically adjacent to the roof structure. This allows the area to be roofed and the space within the roof structure to be advantageously expanded without restricting access to the space within the roof structure or the pair of roof structures. The roof structure and the further roof structure are advantageously connected to each other at their farther ends and together form a gable roof. The off-center arrangement of the support groups according to the invention is particularly advantageous because this arrangement allows the pair of roof structures to be accessed from all four sides, in particular making them accessible by vehicle and on foot.A connection of the roof structures at an end of the support unit opposite the more distant end is also advantageous, since the off-center arrangement of the support groups means that the first support groups and the second support groups are arranged in such a way as to form a support group composite.

[0018] In a further development of the first roof structure pair, it is provided that a drainage channel and / or connecting sheet metal profiles are arranged between the roof structure and the further roof structure and / or that the first roof structure and the further roof structure are directly connected to each other.

[0019] Furthermore, the present problem is solved by a structural extension which is identical in construction to the roof structure according to the invention, with the proviso that the structural extension has one fewer second support group and one fewer second crossbeam element than the roof structure, wherein the structural extension is arranged parallel to a first transverse plane and mirror-symmetrically adjacent to the roof structure. Advantageously, the roof structure can be extended along the longitudinal plane by the structural extension to form a second pair of roof structures. Particularly advantageously, a second support group and a second crossbeam element of the structural extension are formed by the second support group and the second crossbeam element of the roof structure.

[0020] Finally, the problem is further solved by a building system comprising at least one roof structure according to the invention and / or at least one first pair of roof structures according to the invention. In a further development of the invention, it is provided that the building system comprises at least one structural extension, wherein at least one structural extension is arranged on at least one of the at least one roof structure and / or the at least one first pair of roof structures. The building system has a modular design and can be expanded or reduced as needed, depending on the application, which allows for versatile use.

[0029] Figure 1A shows a perspective view of a first embodiment of a roof structure 1, comprising a support unit 2 and a first support group 5a and a second support group 5b. The support unit 2 includes a first crossbeam element 3a, which is positively connected to a second end region 7 of the first support group 5a by means of concealed screws. The support unit 2 further includes a second crossbeam element 3b, which is arranged parallel to and spaced apart from the first crossbeam element 3a and is positively connected to a second end region 7 of the second support group 5b by means of concealed screws. Three longitudinal beam elements 4 are arranged between the first crossbeam element 3a and the second crossbeam element 3b, each of which is oriented orthogonally to the two crossbeam elements 3a and 3b.The two outermost longitudinal beam elements 4 and the two crossbeam elements 3a, 3b together form the rectangular frame shape of the beam unit 2. Both the crossbeam elements 3a, 3b and the longitudinal beam elements 4 are designed as I-beams. The longitudinal beam elements 4 are bolted to the crossbeam elements 3a, 3b and have an identical cross-section. Furthermore, the longitudinal beam elements 4 are spaced from one end 16, which is further away from the two support groups 5a, 5b, such that the more distant ends 16 of the crossbeam elements 3a, 3b project beyond a rectangle formed by the longitudinal beam elements 4 and the crossbeam elements 3a, 3b. Likewise, the ends of the crossbeam elements 3a, 3b opposite the more distant ends 16 also project beyond the rectangle formed by the longitudinal beam elements 4 and the crossbeam elements 3a, 3b. The first and second support groups 5a, 5b each have two support columns 8.The two support columns of the first and second support groups 5a, 5b are welded to a common base plate 17 at a first end region 6 of the respective support groups 5a, 5b. The support columns 8 have an identical cross-section and are rectangular tube-shaped. The two support columns 8 of the first support group 5a and the second support group 5b are each welded to a support bearing 25 at the second end region 7. The support bearing 25 has concealed through-holes for connection by means of screws to the first crossbeam element 3a and the second crossbeam element 3b. The support bearing 25 is arranged parallel to the first and second crossbeam elements 3a, 3b. Thus, a first transverse plane 11 is defined by the support columns 8 and the support bearing 25 of the first support group 5a, and the first crossbeam element 3a is also located in the first transverse plane 11.A second transverse plane 12 is defined by the support columns 8 and the support bearing 25 of the second support group 5b, with the second crossbeam element 3b also located in the second transverse plane 12. A roof angle is defined between the mounting surface (not shown) and the first crossbeam element 3a, as well as between the mounting surface (not shown) and the second crossbeam element 3b, and between a first horizontal axis 26 oriented parallel to the mounting surface in the operating position and the first crossbeam element 3a, and between a second horizontal axis 27 oriented parallel to the mounting surface in the operating position and the second crossbeam element 3b. <p ausgebildet. Zwischen sämtlichen Stützsäulen 8 der ersten Stützgruppe 5a und zwischen sämtlichen Stützsäulen 8 der zweiten Stützgruppe 5b ist jeweils ein Gesamtstützwinkel y von kleiner gleich 40° ausgebildet.

[0030] Figure 1B shows a perspective view of a roof structure 1 according to a second embodiment, comprising a support unit 2 and a first support group 5a and a second support group 5b. The support unit 2 includes a first crossbeam element 3a, which is positively connected to a second end region 7 of the first support group 5a by means of concealed screws. The support unit 2 further includes a second crossbeam element 3b, which is arranged parallel to and spaced apart from the first crossbeam element 3a and is positively connected to a second end region 7 of the second support group 5b by means of concealed screws. Three longitudinal beam elements 4 are arranged between the first crossbeam element 3a and the second crossbeam element 3b, each of which is oriented orthogonally to the two crossbeam elements 3a and 3b.The two outer longitudinal beam elements 4 and the two crossbeam elements 3a, 3b together form the rectangular frame shape of the beam unit 2. Both the crossbeam elements 3a, 3b and the longitudinal beam elements 4 are designed as I-beams, with end plates 23 at their ends. The longitudinal beam elements 4 are bolted to the crossbeam elements 3a, 3b and have an identical cross-section. Furthermore, the longitudinal beam elements 4 are spaced from an end 16 furthest from the two support groups 5a, 5b, such that the furthest ends 16 of the crossbeam elements 3a, 3b project beyond a rectangle formed by the longitudinal beam elements 4 and the crossbeam elements 3a, 3b. Likewise, the ends of the crossbeam elements 3a, 3b opposite the furthest ends 16 also project beyond the rectangle formed by the longitudinal beam elements 4 and the crossbeam elements 3a, 3b.The first and second support groups 5a, 5b each have four support columns 8, namely one vertical column 9, two transverse columns 10, and one longitudinal column 13. The vertical column 9 is oriented essentially perpendicular to a mounting surface (not shown) and is framed by the transverse columns 10 and the longitudinal column 13. The vertical column 9 and the two transverse columns 10 of the first and second support groups 5a, 5b are welded to a common base plate 17 at a first end region 6 of the respective support groups 5a, 5b. This base plate 17 has through holes 24 for mounting the roof structure 1 to a mounting surface (not shown) in use, in particular using screws or bolts (not shown). The longitudinal column 13 is welded to a further base plate 17, which is located directly next to the base plate 17 of the vertical column 9 and transverse columns 10.The additional base plate 17 also has through holes 24 for fastening it to the mounting surface (not shown) during use. The support columns 8 have an identical cross-section and are rectangular tubes. The vertical support 9 and the two transverse supports 10 of the first support group 5a and the second support group 5b are each welded to a support bracket 25 at their second end region 7. The support bracket 25 itself has through holes (not visible) for connecting it to the first crossbeam element 3a and the second crossbeam element 3b by means of screws. The support bracket 25 is arranged parallel to the first and second crossbeam elements 3a and 3b. Thus, the vertical support 9, the two transverse supports 10, and the support bracket 25 of the first support group 5a define a first transverse plane 11, in which the first crossbeam element 3a is also located.A second transverse plane 12 is defined by the vertical support 9, the two transverse supports 10, and the support bearing 25 of the second support group 5b, with the second crossbeam element 3b also located in the second transverse plane 12. A longitudinal plane 14 is defined by the vertical supports 9 and the longitudinal supports 13 of the first and second support groups 5a, 5b, which is oriented orthogonally to the first transverse plane 11 and the second transverse plane 12. The beam element 2 additionally includes bracing elements 18 in the form of round steel elements, spanning within the rectangle formed by the longitudinal beam elements 4 and the two transverse beam elements 3a, 3b. A roof angle is located between the mounting surface (not shown) and the first crossbeam element 3a, and between the mounting surface (not shown) and the second crossbeam element 3b. <p ausgebildet.Between all transverse supports 10 of a support group 5a, 5b and the vertical support 9 of the same support group 5a, 5b a first support angle a is formed and between all longitudinal supports 13 of a support group 5a, 5b and the vertical support 9 of the same support group 5a, 5b a second support angle ß is formed.

[0031] Figure 2 of the second embodiment shows a second perspective view of the roof structure 1, wherein the support unit 2 has a trapezoidal sheet 20, the ends of which are covered by connecting sheet profiles 21. The trapezoidal sheet 20 is essentially rectangular and projects beyond all sides of the rectangular frame formed by the crossbeam elements 3a, 3b and longitudinal beam elements 4, so that the crossbeam elements 3a, 3b and the longitudinal beam elements 4 are at least partially protected from environmental influences. Furthermore, the roof structure 1 has a downpipe 19 at the end of the crossbeam elements 3a, 3b opposite the more distant end 16, which is arranged essentially parallel to the vertical support 9 of the first support group 5a. The downpipe 19 serves for the controlled drainage of rainwater.Figure 3 of the second embodiment shows a perspective view of a first roof structure pair 100, wherein the first roof structure pair 100 comprises two roof structures 1, 1' which are arranged symmetrically to each other parallel to a longitudinal plane 14, which is defined by the orientation of the vertical supports 9 and longitudinal supports 13 of the roof structure 1. In this embodiment of the first roof structure pair 100, the ends opposite the more distant ends 16 of the roof structures 1, 1' abut each other and are connected to form the first roof structure pair 100 by means of concealed screws. Due to the off-center arrangement of the partially visible support groups 5a, 5a', 5b, 5b' of the roof structures 1, 1', access to a space within the first roof structure pair 100 is only minimally restricted.The roof structures 1 , 1 ' have a drainage channel 101 at their line of contact, which is connected to the downpipe 19 arranged between the first support groups 5a, 5a', so that rain can be drained in a controlled manner.

[0032] Figure 4 of the second embodiment shows a perspective view of a second roof structure pair 200, wherein the second roof structure pair 200 comprises, in addition to the roof structure 1, a structural extension 201, parallel to a first transverse plane 11 defined by transverse supports 10 and vertical supports 9 of the first support group 5a, and mirror-symmetrically adjacent to the roof structure 1. The structural extension 201 is identical in construction to the roof structure, with the exception of the missing second support group 5b and the second crossbeam element 3b. Rather, in this embodiment, the second support group 5b and the second crossbeam element 3b are formed by the second support group 5b and the second crossbeam element 3b of the roof structure 1, which are shown schematically here.The roof structure 1 and the structural extension 201 thus share the second support group 5b and the second crossbeam element 3b, wherein the shared support group 5b comprises a vertical support 8 (not shown), two transverse supports 10 (not shown), and two longitudinal supports 13 (not shown). In this embodiment, the vertical support 8 is alternately surrounded by the two transverse supports 10 and the two longitudinal supports. Accordingly, the roof structure 1 and the structural extension 201 are connected to the second roof structure pair 200 via screw connections. The trapezoidal sheets 21 of the roof structure 1 and the structural extension 201 are connected to each other in such a way that they accommodate a drainage channel 101 between them.

[0033] Figure 5 of the second embodiment shows a perspective view of a building system 300, wherein the building system 300 comprises two first roof structure pairs 100 and four roof structures 1 of the two first roof structure pairs 100 corresponding to supplementary structural extensions 201. These components are arranged relative to one another such that they together form a building system 300 which at least partially protects a space located within the building system 300 from environmental influences, wherein the corresponding support groups 5a, 5b of the roof structures 1 and the structural extensions 201 are arranged relative to one another such that a car can drive through at least between every second support group 5a, 5b. A plurality of photovoltaic systems 301 are arranged on the building system 300. In this advantageous embodiment, a mounting surface of the building system 300 is formed by a foundation 302.
