Description

[0001] Roof construction for a carport or shelter with longitudinal and transverse struts that are directly or indirectly connected to each other in the corner areas of the roof.

[0002] WO 2015 / 028174 A1 discloses a roof construction with a supporting structure. Pivoting louvers are attached to the supporting structure, forming a continuous roof surface when closed. When opened, with the louvers pivoted, spaces are created between the louvers. The louvers are equipped with photovoltaic modules. The pivoting position of the louvers allows for the ideal allocation to the solar radiation. Furthermore, the open position of the louvers allows ventilation of the area below the roof.

[0003] A similar roof construction is also known from DE 10 2016 117 772 A1

[0004] The object of the invention is to provide a roof structure of the type mentioned above, equipped with photovoltaic modules, which has a simple design and enables good power yield even with different solar radiation angles on the roof surface. In particular, the object of the invention is also to provide a roof structure that, while maintaining a flat appearance, offers effective drainage of the roof surface and also allows for self-cleaning.

[0005] This object is achieved with the features of claim 1. Accordingly, it is provided that the longitudinal struts are coupled to one another via support struts which extend at least partially between the longitudinal struts, wherein at least one support strut has surface elements connected to opposite sides thereof, which form part of the roof surface and which are at an angle to one another to form a roof slope for draining rainwater such that the surface elements run inclined to the horizontal in the direction of the support strut and the upper sides of the surface elements are arranged in a V-shape relative to one another, wherein the support strut has a gutter into which the upper sides of the surface elements drain and which extends in the longitudinal direction of the support strut up to at least one of the longitudinal struts, and wherein the surface elements are equipped with photovoltaic elements which are covered with a light-permeable pane,The panes form, at least in part, the upper surface of the surface elements. This pane can be, for example, a glass pane or a plastic pane,

[0006] In this roof construction, the surface elements are set at alternating angles to one another in the direction of the longitudinal extension of the longitudinal struts. The included angle between two adjacent surface elements can preferably be selected in the range between 3 and 15 degrees. This results in a zigzag-shaped structure for the surface elements. In particular, this structure can be such that an adjacent ascending surface element is connected to one side of a surface element and an adjacent descending surface element is connected to the opposite side. This results in a kit-like construction that can be varied as desired depending on the size of the roof. As a result of the surface elements being set at an angle to one another, some of the surface elements are not ideally aligned with the sun, but the remaining surface elements are positioned particularly advantageously towards the sun.The roof structure is kept simple and drainage can be carried out reliably and without high structural effort.

[0007] According to an advantageous embodiment of the invention, the surface elements can be supported on their sides facing away from the support strut on additional support struts, with the support points of the additional support struts being offset from the support points of the support struts, counter to the direction of gravity, in order to form the slope. This simple measure allows the roof structure to be erected quickly and easily with minimal component costs.

[0008] A visually appealing and compact design can be achieved particularly by having at least one of the support struts have spaced-apart side walls connected by a base, and by holding the channel in the area between the side walls and connecting them to them. A high section modulus against bending can be achieved via the side walls, especially when they are arranged vertically. The channel is visually integrated into the area surrounded by the support strut.

[0009] In particular, it can be provided that connecting pieces are coupled to the side walls, which extend into the area between the side walls, that the two connecting pieces support the gutter, and that at least one section of the connecting pieces is inclined at a gradient toward the gutter. The connecting pieces form the supply areas to the gutter and thus ensure the reliable introduction of water coming from the roof surface into the gutter. This prevents water from accidentally dripping into the roof installation area.

[0010] To reduce the parts and assembly effort, the gutter can be designed as a hollow profile and connected in one piece to the side walls via the connecting pieces.

[0011] In a preferred variant of the invention, the channel has two spaced-apart edges that run in the longitudinal direction of the profile and between which an inlet area is formed into the pipe area enclosed by the channel. The edges can, in particular, form drip edges to ensure reliable drainage.

[0012] One conceivable alternative invention is for the gutter to be covered by a cover profile extending in the longitudinal direction of the support strut, and for the cover profile to form or delimit passages that create a spatial connection between the channel section of the gutter and a supply section of the support strut leading to the gutter. The support profile prevents the gutter from becoming dirty, for example, with leaves. The passages can be dimensioned so that water is reliably directed into the gutter while preventing the gutter from becoming clogged with coarse debris.

[0013] A simple design for the cover profile is achieved if the cover profile has a cover wall to which two spaced-apart side parts are connected, and if the side parts have recesses in the area facing away from the cover wall to form the openings. It is also conceivable for the side parts to have locking elements in the area facing away from the cover wall, by means of which the cover profile can be releasably locked to the support strut. The locking elements allow the cover profile to be securely connected to the support strut. For cleaning purposes, for example, when the gutter needs to be cleaned, the cover profile can be easily removed and reinstalled after cleaning.

[0014] To achieve high power yield, the roof area covered by photovoltaic modules must be maximized as much as possible. To meet this requirement, the invention can provide for the surfaces of the panel elements adjoining the support strut to extend up to the top wall of the cover profile, maintaining a gap, with the panel elements overlapping the underlying support strut in the area of ​​their sides facing the cover profile. The gap can be selected to be particularly small, taking into account the thermal expansion of the panel elements and / or the mechanical play of the panel elements in the surface of the roof plane. The construction described above has the additional advantage that the sides of the panel elements facing the cover profile form drip edges to enable reliable drainage and prevent capillary effects.

[0015] If the supporting strut(s) are designed as extruded profiles, preferably extruded aluminum profiles, complex component geometries for the supporting strut can be implemented easily and cost-effectively. Using extruded aluminum profiles results in a particularly lightweight construction. Extruded profiles can be easily cut to the desired length from a profile strip, further simplifying the modular construction of the roof structure.

[0016] To improve the modular design, it can additionally or alternatively be provided that the support struts are connected to one another by means of connecting profiles. The connecting profiles directly or indirectly support the edges of two surface elements arranged next to one another in the longitudinal direction of the support strut. The connecting profile forms a conduit area that runs at a gradient between two adjacent support struts and drains into the gutter of one of the support struts. In this way, the modular design can be extended not only in the direction of the longitudinal extension of the longitudinal struts, but also in the direction of the longitudinal extension of the transverse struts.

[0017] A roof construction according to the invention can be designed such that the longitudinal ends of the support strut(s) are covered with cladding elements, wherein outlets are provided in the area of ​​the cladding elements through which the duct area formed by the gutter is transferred into a duct area of ​​the longitudinal strut or a duct area associated with the longitudinal strut. The cladding elements can be used to create a uniform finish for the longitudinal ends of the support struts in a visually appealing manner.

[0018] The invention is explained in more detail below with reference to an embodiment illustrated in the drawings. They show: Fig. 1 in perspective view a carport, Fig. 2 the carport according to Fig. 1 with partially open roof, Fig. 3 the carport according to the Fig. 1 and Fig. 2 in a partial representation and in a partially assembled state, Fig. 4 the carport according to the Fig. 1 to 3 in a partially assembled state and in partial representation as well as in view of the long side of the carport, Fig. 5 one of the Fig. 4 taken detail, Fig. 6 another detail of the carport, Fig. 7 the representation according to Fig. 6 in enlarged partial view and Fig. 8 a sectional view of the carport in the roof area.

[0019] Fig. 1 shows a carport. However, the following explanations apply not only to carports, but also to other shelters. Accordingly, the Fig. The construction shown in 1 to 8 can be used for any type of shelter.

[0020] How Fig. As shown in Figure 1, a roof structure is provided that is supported by four posts 10. Of course, more or fewer posts 10 can also be provided. The posts 10 are anchored to the ground in the area of ​​their base 12. The head 11 of the posts 10, facing away from the base 12, is connected to the roof structure, preferably by screwing.

[0021] One or all posts 10 may be equipped with downpipes 13 for drainage.

[0022] The roof structure comprises two parallel transverse struts 20 that run in the transverse direction of the roof structure. Furthermore, the roof structure comprises two parallel longitudinal struts 30 that run in the longitudinal direction of the roof structure.

[0023] The cross braces 20 and the longitudinal braces 30 meet in pairs in the corner area of ​​the roof structure and are connected to each other there. Furthermore, a post 10 is connected to each of these corner areas.

[0024] A receiving area is created in the area surrounded by the transverse struts 20 and the longitudinal struts 30. A plurality of surface elements 40 are installed in this receiving area. The surface elements 40 have solar panels 42 covered with a light-permeable pane 41, preferably a thermally or chemically tempered glass pane. The panes 41 form the cover surface and thus the upper side of the surface element 40.

[0025] In the present embodiment, two surface elements 40 are arranged in a row along the longitudinal extension of the cross struts, with the surface elements 40 being aligned with each other. For larger shelters or carports, more than two surface elements 40 may be arranged in a row along the cross struts 20.

[0026] Four surface elements 40 are arranged in a row in the direction of the longitudinal extension of the longitudinal struts 30. As Fig. 1, the surface elements 40 are arranged in a zigzag shape relative to one another in the direction of the longitudinal extension of the longitudinal struts 30.

[0027] In the zigzag arrangement, the discs 41 of the surface elements 40 directly adjacent to the cross struts 20 are, for example, inclined downwards from the cross struts 20. These surface elements 40 are preferably followed by another surface element 40 in the direction of the longitudinal extension of the longitudinal struts 30, which is inclined in the opposite direction, i.e., inclined upwards. Accordingly, an included angle of <180°, measured from the top side, results between these two surface elements 40. In other words, the two surface elements 40 are arranged in a V-shape relative to one another.

[0028] The ascending surface element 40 is followed by a descending surface element 40. The discs 41 of these adjacent surface elements 40 accordingly enclose an angle greater than 180°, measured from the top side.

[0029] Particularly preferably, this angle is chosen in the range between 3 and 15 degrees within the scope of the invention, thereby achieving an optimal power yield for different angles of incidence of the sun.

[0030] In Fig. Figure 2 shows a partial assembly position in which four surface elements 40 have been removed. As this illustration shows, the longitudinal struts 30 are connected to one another by means of support struts 50, 60. In particular, the support struts 50, 60 can run parallel to one another and parallel to the transverse struts 20.

[0031] The support struts 50,60 are attached to the longitudinal struts 30, in particular screwed.

[0032] Connecting profiles 70 are provided in the area where two surface elements 40, arranged in a row along the longitudinal extension of the cross struts 20, meet. These connecting profiles 70 connect two parallel and adjacent support struts 50, 60.

[0033] The connecting profiles 70 have a drainage channel and support sections for the edges of the adjacent surface elements 40.

[0034] Water flowing laterally from the surface of the surface elements 40 can enter the drainage channel of the connecting profiles 70.

[0035] By means of the support sections, the edges of the surface elements 40, which extend on the row side in the direction of the longitudinal struts 30, can be underpinned and supported.

[0036] The drainage channels of the connecting profiles 70 are laid with a gradient, as for example Fig. 3. This gradient allows the water in the drainage channel to be directed toward the support struts 60. For example, the surface elements 40 can also be placed on the connecting profiles 70 with sealing profiles interposed. These sealing profiles can be made of an elastic material, for example, in particular a plastic profile. In such a case, drainage can also occur past the sealing profiles and into the connecting profiles 70.

[0037] The following is based on reference to Fig. 5 explains the structure of the support struts 50. As this drawing shows, the support struts 50 have parallel side walls 51 that are connected to each other by a base 52. On the side facing away from the base 52, the side walls 51 merge into connecting pieces 54. Screw channels 53 can be provided in the transition area between the side walls 51 and the connecting pieces 54. The longitudinal axes of the screw channels 53 then extend in the direction of the longitudinal axis of the support strut 50.

[0038] The connecting pieces 54 are connected to a gutter 55 facing away from the side walls 51. The connecting pieces 54 form an acute angle with the facing side walls 51, so that the connecting pieces 54 slope downwards relative to the horizontal to enable drainage.

[0039] The channel 55 has a channel bottom 57. From this channel bottom 57, channel walls 56 rise, arranged at a distance from one another. Retaining elements 58 are connected to the channel walls 56, facing away from the channel bottom 57. These retaining elements 58 project inward and face one another. A spaced area is provided between the ends of the retaining elements 58.

[0040] A cover profile 90 can be used to cover the channel 55. The cover profile 90 serves to cover the inlet area into the channel 55.

[0041] How Fig. As shown in Figure 5, the cover profile 90 can be configured to have a cover wall 91. Two side parts 92 are connected to the cover wall 91, and the side parts 92 protrude toward the channel 55. The free ends of the side parts 92 are equipped with locking elements 93. The locking elements 93 are designed to engage with the retaining elements 58 of the channel 55 to form a locking connection. Accordingly, the cover profile 90 can be placed onto the channel 55 from above and locked thereto.

[0042] Fig. Figure 5 shows that the side parts 92 can be provided with passages 94. The passages 94 can, for example, be designed in the form of recesses formed in the free edges of the side parts 92. The passages 94 create a water-conducting connection between the conduit area surrounded by the channel 55 and the upper side of the connecting pieces 54. Additionally or alternatively, the connecting pieces 54 can also be provided with passages.

[0043] How Fig. 6 and Fig. 7 show, in addition to the support struts 50, further support struts 60 are installed. The support struts 60 essentially have the same structure as the support struts 50. In contrast to the support struts 50, the overall height of the side walls 61 of the support struts 60 is selected to be greater than the overall height of the side walls 51 of the support struts 50. The statements made above with regard to the support struts 50 therefore also apply equally to the support struts 60. To avoid repetition, reference will be made to the above statements. Accordingly, the support struts 60 have side walls 61, a base 62, screw channels 63 and connecting pieces 64. The channel 65 is again connected in one piece to the connecting pieces 64. The channel 65 has a channel base 67 and channel walls 66. Furthermore, holding elements 68 are provided.

[0044] The support struts 50,60 can be designed as extruded profiles

[0045] The support struts 50, 60 are installed in the roof structures so that the bases 52, 62 of the support struts 50, 60 are arranged at the same height or approximately at the same height. Due to the different component heights of the side parts 52, 62, the transition areas between the side walls 51 and the connecting pieces 54, 64 of the support struts 50, 60 are arranged at different heights. The connecting profiles 70 are supported in these areas. The inclination of the connecting profiles 70 is determined by the height difference and the spacing of the support struts 50, 60.

[0046] Two adjacent surface elements 40 can be supported accordingly on two connecting profiles 70 arranged at a distance from one another.

[0047] However, it is also conceivable, as for example in Fig. 5 shows that the edge-side surface elements 40 of the roof structure are supported on panels 80 in their areas facing the cross struts 30. The panels 80 have a wall element 81 from which a support section 85 is bent. A bend 86 is bent back from the support section 85. The surface elements 40 can be supported on the support section 85 at the edges in the area of ​​the cross struts 30.

[0048] The wall elements 81 of the panels 80 can extend vertically up to the undersides of the support struts 50,60, as Fig. 5. This creates a visual finish. Bolts 82 are provided on the cross struts 30 for fastening the panels 80. The panels 80 have suspension receptacles 84 at their longitudinal ends, forming a hook 83. The hooks 83 allow the panels 80 to be hung on the bolts 82, thus enabling quick and easy installation.

[0049] How Fig. As shown in Figure 3, cladding elements 31 can be placed on the front sides of the longitudinal ends of the support struts 50, 60. The cladding elements 31 can be designed as wall elements that extend vertically and have a beveled fastening wall 33 at their upper edge. For fastening the support struts 50, 60, fastening receptacles 34 are provided, which can be arranged in alignment with the screw channels 53, 63 of the support struts 50, 60. The cladding elements 31 can be securely connected to the support struts 50, 60 by means of fastening screws that are passed through the fastening receptacles 34 and screwed into the screw channels 53, 63.

[0050] To connect to the cross brace 30, the fastening wall 33 is placed on a support section of the cross brace 30. As Fig. As can be seen in Figure 3, the mounting walls 33 are equipped with several screw receptacles. Mounting screws can be passed through these screw receptacles and screwed into the cross braces 30. In this way, the support braces 50, 60 can be connected to the cross braces 30.

[0051] The cladding elements 31 have openings 32. These openings 32 adjoin the guide area defined by the connecting pieces 54. Thus, water flowing through the connecting pieces 54 can flow not only through the openings 94, but also toward the cross brace 30. The water is then collected in a separate collecting channel in the area of ​​the cross brace 30 and directed toward the posts 10. At the posts 10, the water is then drained into the downpipe 13.

[0052] The water which is drained through the gutter 55,65 also flows via end outlets 59 of the gutter into the separate collecting gutter of the cross member 30 and is fed to the downpipe 13.

[0053] This creates a roof structure that enables reliable drainage. Water accumulating on the upper surfaces of the surface elements 40 is either drained directly into the gutters 55, 65 or channeled into the gutters 55, 65 via the connecting profiles 70. At the longitudinal ends of the gutters 55, 65, the water is then directed to the cross braces 30 and, from there, via a separate collecting channel, to the downpipes 13 of the posts 10.

[0054] The cover profile 90 prevents coarse debris, such as leaves, from entering the gutters 55, 65. To clean the gutters 55, 65, the cover profile 90 can be easily removed. The gutters 55, 65 can then be cleaned with a brush. The cover profile 90 can then be snapped back on.

[0055] In order to prevent uncontrolled dripping of water in the area of ​​the longitudinal struts 20, as Fig. As shown in Figure 8, additional profiles 23 are attached to the cross struts 20. The additional profiles 23 are attached to the inside of the cross strut 20, facing away from the outer side 21. The additional profiles 23 have a bottom chamber wall 23.1 and adjoining lateral chamber walls 23.2. The chamber wall 23.2 merges into a beveled groove 23.3. The additional profile 23 encloses a channel 23.4.

[0056] The free end of the channel 23.3 is again equipped with locking elements. The chamber wall 23.2 also has such locking elements. Cover profiles 90 can be locked into place with these locking elements. The cover profiles 90 are preferably identical in construction to the cover profiles 90 described above. The design of the cover profiles 90 can be such that a cover wall 22 of the cross strut 20 merges flush with the cover wall 91 of the cover profile 90.

[0057] The water draining from the transverse sides of the surface elements 40, which run parallel to the cross braces 20, can reach the area of ​​the additional profile 23. The water then flows through the gutter 23.3 and into the channel 23.4. The channel 23.4 is again drained towards the downpipes 13.

[0058] How Fig.As shown in Figure 8, a fastening piece 23.5, which can be designed as an extruded profile, is provided for connecting the channel 23.3. The fastening piece 23.5 is connected to the cross brace 20 via connecting pieces 23.6.

[0059] The roof structure described above is suitable for a carport or any other type of shelter. The roof structure comprises longitudinal and transverse struts 20, 30 that are directly or indirectly connected to one another in the corner areas of the roof. The longitudinal struts 30 are coupled to one another via support struts 50, 60 that extend at least partially between the longitudinal struts 30. The support struts 50, 60 can preferably be arranged at the same distance from one another to realize a modular design.Connected to at least one of the support struts 50 on opposite sides are surface elements 40 which form part of the roof surface and which are at an angle to one another in order to form a roof slope for draining rainwater. The surface elements 40 run inclined to the horizontal in the direction of the support strut 50 and the upper sides of the surface elements 40 are arranged in a V-shape relative to one another. The support strut 50 has a gutter 55 into which the upper sides of the surface elements 40 drain and which extends in the longitudinal direction of the support strut 50 as far as at least one of the longitudinal struts 30. According to the invention, the surface elements 40 have photovoltaic elements. They can be covered with a pane 41 which is permeable to UV radiation, the panes 41 forming the upper side of the surface elements 40 at least in some regions. QUOTES CONTAINED IN THE DESCRIPTION
