    专利说明:

    The invention relates to a support structure for holding at least one row of vertically arranged PV modules, comprising spaced in the row direction vertical posts which are attached to support feet with which the support structure can be mounted on a substructure, with successive Post in a row, a PV module can be mounted directly on the post and / or on at least one horizontal bar running between the posts.
    Conventionally, photovoltaic (PV) modules are mounted in an inclined position, whereby they are mostly oriented to the south. Such PV modules are unifacial, i.e. only have an active surface on the top.
    In bifacial PV modules, which have an active surface on both sides, the assembly takes place vertically, often in a north-south orientation, so that the power peaks are reached in the morning and evening. A vertical arrangement of, preferably bifacial, PV modules can also advantageously be provided in snowy areas.
    A support structure of the type mentioned for vertical mounting of PV modules emerges from WO 2018/115120 A2. The vertical posts are anchored here in particular in the ground, with C-profiles, which form support feet for the vertical posts, being introduced into the ground.
    [0005] If vertically arranged PV modules are to be set up on flat roofs, the roof skin should not be penetrated. As a substructure to which support feet of the supporting structure are attached, corrugated plastic sheets can be provided here, onto which a bed is applied. In this case, parallel rails can be provided between the support feet and the corrugated plastic sheets, which are also attached to the corrugated plastic sheets. Such a type of substructure leads to building tolerances in the position of the mounting points for the support feet, including the fact that flat roofs are usually not completely flat and also have a certain incline.
    Such support structures must be able to withstand large wind loads due to the flat design of the vertically arranged PV modules.
    Due to the thermal dilation, which the support structure is exposed to, such support structures for vertically oriented PV modules generally after a few modules arranged separation points to minimize the effects of thermal dilation in the row direction, or consist of separate units that contain only one module or only a few modules (usually 1-6). Particularly in the case of vertically arranged PV modules, individual modules would tend to deviate from an essentially straight row due to constraining forces.
    The object of the invention is to provide a support structure of the type mentioned, with which vertically arranged PV modules can be mounted in an advantageous manner, whereby a recording of thermal dilatations is made possible in the horizontal direction. According to the invention, this is achieved by a supporting structure with the features of claim 1.
    In the supporting structure according to the invention, at least the posts lying between the other posts of the at least one row, ie the posts not lying at the two ends of the at least one row, each have a first and a second sub-post, the first and second Partial posts have mobility against each other in the row direction. The PV module located on one side of this post and / or the at least one horizontal bar located on one side of the post can be fastened to the first partial post. The PV module on the other side of this post and / or the at least one horizontal bar on the other side of this post can be fastened to the second partial post.
    Due to the design according to the invention, thermal dilatations can be recorded on a respective post. As a result, a continuous row with a plurality of PV modules, preferably more than five, particularly preferably ten or more PV modules, can be formed in an advantageous manner.
    A support structure according to the invention is particularly suitable for arrangement on a flat roof.
    A possible embodiment of the invention provides that the two sub-posts are each movably mounted relative to the support foot associated with this post, so that the two sub-posts are movable independently of one another relative to the support foot in the row direction (in a certain area). In principle, it would also be conceivable and possible for such a movable mounting relative to the support foot to be carried out for only one of the two sub-posts, while the other sub-post is rigidly connected to the support base.
    Another possibility is that the support feet are designed to be elastically deformable, so that at least one of the two sub-posts can be moved in the row direction by elastic deformation of the support foot. Both partial posts are preferably movable independently of one another in the row direction by a respective deformation of a different part of the support foot. The partial posts can be rigidly connected to the respective support foot. A particularly advantageous embodiment provides that the support feet are also formed by two separate components, the first support foot part being rigidly connected to the first partial post and the second support foot part rigidly connected to the second partial post. During the assembly of the supporting structure on the substructure, the relative position of the two support foot parts can be adapted to the existing construction tolerances, for example by means of elongated holes in the support foot parts through which screws pass. A particularly large adaptability to structural tolerances can thereby be achieved.
    Mutual mobility of the two sub-posts in the row direction can also be made possible in that the first sub-post is rigidly connected to a first support foot part and the second sub-post is rigidly connected to a second support foot part, with at least one of the two support foot parts being separate components represent, preferably both support foot parts is or are movably mounted with respect to the substructure.
    In an advantageous embodiment of the invention, the two partial posts of a respective post each have a base web and, at the two ends of the base web, side legs projecting from this in the direction of the other partial post. The side legs of the two partial posts overlap here over sections adjoining their free ends. As a result, the two partial posts can be pushed into one another to a greater or lesser extent. The space completely surrounded by the two partial posts can be used, for example, to guide cables. In particular, the two partial posts are U-profiles which can be pushed into one another at right angles to the direction of their longitudinal extension.
    In an advantageous embodiment of the invention, the support feet on which the posts lying between the other posts of the at least one row are attached, preferably all support feet, at least one base web attachable to a substructure and upwardly protruding from this first and second fastening webs , between which a lower end portion of the post protrudes. The fastening webs are advantageously at right angles to the row direction. In one possible embodiment of the invention, the at least one bottom web can have elongated holes which extend parallel to the row direction and through which screws can be passed through for fastening to a substructure.
    An advantageous embodiment of the invention provides that the first sub-post is rigidly connected to the first fastening web and the second sub-post is rigidly connected to the second fastening web and the fastening webs in the connection area with the sub-post have an elastic flexibility parallel to the row direction. Here, the at least one bottom web can be removed in a middle area of the respective support foot in relation to the direction perpendicular to the row direction, this area extending in both directions perpendicular to the row direction beyond the extensions of the partial posts in this direction.
    If the support feet are formed in two parts in an advantageous embodiment of the invention, a first support foot part can have the first fastening web, which is rigidly connected to the first sub-post and a second support foot part have the second fastening web, which is rigidly connected to the second sub-post is, wherein the two support foot parts can be attached to the substructure in different mutual positions relative to the direction at right angles to the row direction. Each of the support foot parts can advantageously have at least one bottom web, from which the respective fastening web protrudes upward, the bottom webs being attachable to the substructure in a more or less large mutual overlap.
    Due to the relative freedom of positioning of the two support leg parts over a certain range in relation to the row direction in connection with the mutual mobility of the two sub-posts, an adaptation to structural tolerances is made possible, which can advantageously be relatively large.
    A respective post is advantageously designed overall in the form of a hollow profile. This is preferably formed by the two partial posts together.
    The invention further relates to a PV system with at least one row of vertically arranged PV modules that are attached to such a support structure. The supporting structure is in particular attached to a substructure which has panels, preferably corrugated plastic sheets, which are covered by a bed.
    Further advantages and details of the invention are explained below with reference to the accompanying drawing. 1 shows an oblique view of three rows of PV modules mounted vertically in a supporting structure, according to an exemplary embodiment of the invention; 2 shows an enlarged section in the area of a support foot; 3 shows an enlarged detail in the upper edge area of a post (from a different viewing direction); Fig. 4 is a plan view; FIG. 5 shows an enlarged detail from FIG. 4 in the area of a vertical post; FIG. 6 shows one of the rows in view; FIG. 7 shows an enlarged detail from FIG. 6 in the area of a support foot; FIG. 8, 9 oblique views of the support foot parts from different viewing directions; 10 shows an oblique view of the supporting structure mounted on a modified substructure; 11 shows an oblique view of a further exemplary embodiment of the invention; FIG. 12 shows an enlarged detail from FIG. 11 in the area of a support foot; FIG. 13 shows an enlarged detail of a view of one of the rows in the area of a support foot; 14 shows an oblique view of a further exemplary embodiment of the invention; FIG. 15 shows an enlarged detail from FIG. 14.
    A first embodiment of the invention is explained below with reference to FIGS. 1 to 9. Vertically arranged PV (photovoltaic) modules 1 are mounted on a supporting structure according to the invention. 1 shows three rows of vertically arranged PV modules 1, three PV modules 1 being contained in each row. In practice, significantly more PV modules can be arranged in a row, for example ten or more.
    The support structure has in the row direction (= in the longitudinal direction of the row of PV modules 1) spaced vertical posts 3. The posts 3 are attached to support feet 4, which in turn are mounted on a substructure. The substructure comprises panels arranged at a distance on the subsurface, in particular a flat roof, which are formed, for example, from corrugated plastic sheets 5, and rails 6 mounted on these panels, which run parallel to one another and at right angles to the row direction 2. A bed is preferably applied over the corrugated plastic sheets 5 (not shown in the figures). The support feet 4 of the various rows are arranged above the rails 6 and rigidly connected to them, preferably by screw connections.
    Horizontal bars 7, 8 run between the posts 3. The PV modules 1 are each held between a lower bar 7, on which they rest, and an upper bar 8.
    Those posts 3 that are not at one end of the respective row (= middle post) each have a first and a second sub-post 3a, 3b, which are separate components.
    The two sub-posts 3a, 3b extend in the exemplary embodiment over the same height.
    The two sub-posts 3a, 3b can be designed as shown in the form of U-profiles and each have a base web 9, 10 and at the two ends of the base web 9, 10 from this in the direction of the other sub-post protruding side legs 11, 12 on. The distance between the side legs 11 of the first partial post 3a is greater than the distance between the side legs 12 of the second partial post 3b. The two partial posts 3a, 3b can thus be inserted more or less far into one another in the direction at right angles to their longitudinal extension with side legs 11, 12 facing each other, with the side legs 11, 12 of the two partial posts 3a, 3b overlapping over sections adjoining their free ends . A channel-like intermediate space 13 is thus formed, surrounded on all sides by the partial posts 3a, 3b, through which, for example, cables for making electrical contact with the PV modules 1 can be passed (not shown in the figures). The sub-posts 3a, 3b thus together form a hollow profile.
    The posts 3 'arranged at the two edges of a respective row can be formed by only one of the two sub-posts 3a, 3b, which have the central posts 3.
    Those support feet 4 that are not at one end of the respective row (= middle support feet) each have in this embodiment a first and a second support foot part 4a, 4b, which are separate components. Each of the two support foot parts 4a, 4b has a bottom web 14, 15 which is removed in a central region of the support foot part 4a, 4b in relation to the direction perpendicular to the row direction 2, that is to say, one could also say that there are for each support foot part 4a, 4b two bottom webs lying in one plane and spaced apart from one another in the direction at right angles to the row direction 2 are present.
    If there are construction tolerances, so for example if the rails 6 have slightly larger or slightly smaller distances from one another than intended, the sub-posts 3a, 3b can be pushed into one another at different distances during assembly of the supporting structure, so that the bottom webs 14, 15 of the Support foot parts 4a, 4b overlap to different extents, wherein the support foot parts 4a, 4b can be screwed to the rails 6 in the corresponding position.
    The lower horizontal bars 7 running below the PV modules 1 each have an elongated base body (which extends at least substantially over the entire length of the bar 7) and fastening tabs protruding upwards and downwards at the two ends of the base body 7a, 7b. In the exemplary embodiment, the base body is designed as a whole as a hollow body (which can consist of several partial profiles), as is preferred. This enables cables to be routed through a respective lower latch.
    The fastening tabs 7a, 7b each rest on a fastening web 16, 17 of a respective support foot part 4a, 4b. In the exemplary embodiment, the fastening tabs 7a, 7b are riveted to the relevant sub-post 3a, 3b together with the fastening web 16, 17 in between (the figures only show the holes 19, 20 for the rivets, but the rivets themselves for the sake of simplicity not). Other types of rigid connection of the fastening webs 16, 17 and the bolts 7 to the partial posts 3a, 3b are also conceivable and possible, for example by means of screw connections or welds. In the area of their lower ends, the sub-posts 3a, 3b are also connected to the fastening webs 16, 17, for example by riveting (for the sake of simplicity, only the holes 21, but not the rivets, are shown in the figures).
    As shown in the exemplary embodiment, at least one fastening point of the respective fastening web 16, 17, with which it is fastened to the respective sub-post 3a, 3b, can be provided, which is above the base body of the respective lower horizontal bolt 7, which is also on this part post 3a, 3b is fastened, for example via fastening tabs 7a, 7b or in some other way.
    A fastening web 16, 17 protrudes upward from the bottom web 14, 15 of the respective support foot part 4a, 4b.
    The fastening webs 16, 17 are aligned at right angles to the row direction 2 and taper upwards.
    The fastening web 16 of the first support foot part 4a is rigidly connected to the first partial post 3a and the fastening web 17 of the second support foot part 4b is rigidly connected to the second partial post 3b. The bottom webs 14, 15, which lie on top of one another and overlap one another, have overlapping elongated holes 14a, 15a which extend in the row direction 2 and are penetrated by screws 18 with which the support feet 4 on the substructure, in the exemplary embodiment on the rails 6 are attached.
    The support feet 4 'arranged on the two edges of a respective row can be formed by only one of the two support foot parts 4a, 4b, which have the middle support feet 4.
    The PV modules 1 are connected to the lower bars 7 by means of holders 22. The holders 22 can be U-profiles, for example, which are connected to the top of the lower bar 7 in the area of their base web, for example by riveting, screwing or welding. In these U-profiles, which are preferably made of metal, rubber-elastic holding parts with a U-shaped cross section can be inserted, on which the PV modules 1 rest with their lower edges (not visible in the figures).
    The upper bars 8 running above the PV modules 1 between the posts 3 hold the PV modules 1 in the region of their upper edges. For this purpose, the upper bolts 8 in the exemplary embodiment are designed in the form of downwardly open U-profiles. In this cross-section, rubber-elastic holding parts are inserted into which the PV modules protrude in the area of their upper edges (not visible in the figures). The two ends of the upper bars 8 are connected to the respective sub-posts 3a, 3b, between which they run. In the exemplary embodiment, the sub-posts 3a, 3b have openings 23 into which the ends of the upper bolts 8 are inserted, a groove being formed on the underside of the upper bolt 8 in which the upper end of the base web 9, 10 of the respective sub-post 3a, 3b is added. In order to prevent the grooves from being pulled out upwards, for example split pins can be inserted into the openings 23 of the sub-posts 3a, 3b above the ends of the upper bolts 8 (not shown in the figures). Other types of attachment of the upper bolt 8 to the post 3 are conceivable and possible.
    The fastening webs 16, 17 of the support feet 4 have an elastic bendability in the row direction in the areas in which they are connected to the sub-posts 3a, 3b. In the exemplary embodiment, this is achieved in particular in that the bottom webs 14, 15 of the support foot parts 4a, 4b are removed in a central area of the respective support foot 4 in relation to the direction perpendicular to the row direction, this area extending in both directions at right angles to the row direction via the in this direction of the present extension of the respective sub-post 3a, 3b also extends. This enables movements of the sub-posts 3a, 3b parallel to the row direction and independently of one another, with elastic deformation of the fastening webs 16, 17.
    Starting from central positions in which the fastening webs 16, 17 have no elastic deformations, each sub-post 3a, 3b is advantageously by at least 2 mm, preferably by at least 4 mm in and against the row direction 2 with elastic deformation of the respective fastening web 16, 17 movable.
    If changes in length occur due to different thermal expansions at different temperatures, here in particular the lower bar 7, such changes in length can thus be absorbed by the supporting structure. Nevertheless, the construction is very stable against wind loads that act at right angles to the row direction.
    The support foot parts can have recesses 31 for the passage of cables, which can also be omitted.
    To assemble the PV system, modular units can advantageously first be formed, which can then be assembled as a whole. Such a modular unit can be formed by a lower bar 8 together with a support foot part 4a or 4b and part posts 3a or 3b attached to a respective end. These modular units can then be continuously connected to one another and to the substructure by means of the screws 18 in order to form the respective row. The PV modules 1 can then be used. For this purpose, a respective PV module 1 is inserted into the holder 22 with its lower edge. As a result, the upper bolt 8 is inserted into the opening 23 of one of the sub-posts 3a, 3b delimiting this assembly area, the upper bolt 8 initially being inclined and then being folded down so that the upper edge of the PV module is received. Furthermore, the upper bolt 7 is inserted into the opening 23 of the opposite partial post 3a, 3b and the upper bolt 8 is fixed in the openings 23, for example by inserting split pins.
    The assembly described above could also be modified in such a way that the assembly of the PV modules 1 already takes place in the formation of the modular units and the already assembled PV modules 1 comprehensive modular units in the sequence to the respective rows be put together and connected to the substructure.
    Different modifications of this exemplary embodiment are conceivable and possible without departing from the scope of the invention as defined in the claims.
    For example, it would be conceivable and possible to design the support feet 4 in one piece. A common bottom web could then be present, which is removed in the middle area (based on the direction at right angles to the row direction). Absorption of thermal expansions by elastic bending of the fastening webs 16, 17 would then also be possible. An adaptability to building tolerances, albeit a smaller one, could be made possible by elongated holes in the base web.
    The attachment of the PV modules 1 could also take place in a different way than described.
    To enable the mobility of the post 3a, 3b in the row direction 2, instead of elastic bending of parts of the support legs 4 or in addition to this, it would also be conceivable and possible that the two support leg parts 4a, 4b or at least one of the support leg parts 4a, 4b in Row direction 2 is movably connected to the substructure. This could be achieved, for example, in that the elongated holes in the bottom webs 14, 15 are not jammed with respect to the screws 18, but rather a mobility with respect to the screws 18 is given. This could also be the case for only one of the support leg parts 4a, 4b.
    Support feet which have separate support foot parts, one of which is rigidly connected to the first partial post 3a and the other to the second partial post 3b and of which at least one is movable in the row direction, could also be designed differently than shown. For example, one of the support foot parts could also be rigidly connected to the substructure and the other support foot part could be mounted movably in the row direction 2 on one support foot part.
    The fastening of the lower bolt 7 to the fastening webs 16, 17 could also be done in another way and the fastening of the fastening webs 16, 17 to the sub-posts 3a, 3b could also be done in another way.
    The lower bars 7 could also be attached directly to the sub-posts 3a, 3b above the fastening webs 16, 17.
    The lower latch 7 could also be fastened to the respective sub-post in a manner other than by means of fastening tabs 7a, 7b, so that the fastening tabs 7a, 7b could also be omitted.
    The posts, support feet and bars (if any) can each consist entirely or partially of metal, preferably folded sheet metal, composite materials, machined extruded profiles, plastic or wood, or combinations thereof.
    The support structure shown in FIG. 10 is of the same design as the support structure shown in FIGS. 1 to 8. The only difference is the substructure. This is formed here only by plates, for example corrugated plastic sheets 5, to which the support feet 4 are attached directly. For example, a separate plate can be provided for each support leg 4. The plates are again covered by a bed, not shown.
    A second embodiment of the invention is shown in FIGS. Apart from the differences described below, the design corresponds to that of the first exemplary embodiment and the description of the first exemplary embodiment and the modifications thereto can be used analogously in this respect.
    In contrast to the embodiment described above, the mobility of the sub-posts 3a, 3b parallel to the row direction 2 is made possible here by a connection to the respective support foot 24 that is movable parallel to this direction. The support feet 24 are preferably formed in one piece. They have a bottom web 25 and fastening webs 26, 27 protruding upward therefrom. The fastening webs 26, 27 are aligned at right angles to the row direction 2 and taper towards the top. The lower ends of the sub-posts 3a, 3b protrude into the space between the fastening webs 26, 27. Connecting bolts 28 extend between the fastening webs 26, 27 and pass through holes in the sub-posts 3a, 3b. The connecting bolts 28 are parallel to the row direction 2 and the sub-posts 3a, 3b can be moved independently of one another with respect to the connecting bolts 28 parallel to the row direction 2.
    For example, the connecting bolts 28 can be designed as shoulder bolts as shown, i.e. a bolt head connects to a shaft of such shoulder bolts on one side and a thread with a thinner diameter onto which a nut is screwed on the other side.
    The mobility of the sub-posts 3a, 3b parallel to the row direction is limited in one direction by the maximum telescoping ability of the sub-posts 3a, 3b, and in the other direction in the extended state by contact with the fastening webs 26, 27.
    To additionally enable adaptation to mounting tolerances, the screws 18, with which the support feet 24 are connected to the substructure, pass through elongated holes aligned parallel to the row direction 2 in the base web 25, these elongated holes in position and shape corresponding to those of the elongated holes 14a, 15a the bottom webs 14, 15 of the first embodiment may correspond. Instead, round holes can also be provided.
    In the fastening webs 26, 27 and / or in the sub-posts 3a, 3b, openings for the connecting bolts 28, which are arranged at different heights, can be present, which enables the post 3 to be adjusted in height.
    There are at least two vertically spaced connecting bolts 28.
    The lower bars 7 are above the fastening webs 26, 27 and are directly rigidly connected to the respective sub-post 3a, 3b. For fastening, the lower bars can in turn have protruding fastening straps which are riveted to the respective partial posts 3a, 3b. The attachment can also take place in another way, for example by screwing.
    The mobility of the sub-posts 3a, 3b in the row direction 2 with respect to the fastening webs 26, 27 could also be designed in a different manner. For example, support feet could be provided with opposite fastening webs aligned parallel to the row direction, between which the lower ends of the respective sub-posts 3a, 3b protrude, the sub-posts 3a, 3b being guided by means of guide bolts in elongated holes extending parallel to the row direction 2.
    The fastening webs could then be connected on opposite sides of the post 3 by connecting webs extending at right angles to the row direction in order to provide sufficient stability in this direction.
    Another embodiment of the invention is shown in FIGS. The differences from the first exemplary embodiment are explained below. Otherwise, the description of the first exemplary embodiment and the modifications described can be used in an analogous manner.
    In this exemplary embodiment, the PV modules 29 have frames 30. The PV modules can be fastened to the partial posts 3a, 3b directly on the vertical frame legs 30a, 30b, for example by means of rivets or screw connections. This means that the lower and upper bolts 7, 8 can be omitted. The partial posts 3a, 3b then do not have to extend over the entire height of the PV modules.
    The support feet 4 are shown in FIG. 15 designed in the same way as in the first exemplary embodiment (but without recesses 31). The support feet thus have first and second support foot parts 4a, 4b, the fastening webs 16, 17 of which are rigidly connected to the respective sub-post 3a, 3b, for example by riveting, in a manner analogous to the first exemplary embodiment (the fastening tabs 7a, 7b of the lower bolts 7 not applicable).
    In addition, a lower and / or upper horizontal bolt could also be provided, to which the lower and / or upper horizontal frame leg 30c, 30d could possibly also be attached.
    The support feet 4 could, however, also be designed in a different manner, for example in a manner analogous to that shown in the second exemplary embodiment.
