Description

The invention relates to a clamping holder which serves for the secure fastening of plate-shaped components, in particular solar modules, to profile carriers.Plate-shaped components are frequently mounted on profile carriers. For example, solar modules are arranged to form a composite having as large a surface area as possible, wherein the individual rectangular solar module plates are arranged along their edges. The solar modules are mounted on the profile carriers and are spaced apart from one another by profile clamps seated on the profile carriers between the individual solar modules. A module clamp which engages over two adjacent solar module edges in each case is mounted on the profile clamps by means of a screw which is screwed from above into a thread of the profile clamp. For the edge regions of the composite there are module clamps with only one leg which engages over an edge solar module and which is likewise fixed from above by means of a screw.The aforementioned panel-shaped components can be mounted both on level, on facades, on flat roofs and on sloping roofs. So-called insertion systems have proven to be particularly successful for sloping roofs, which allow lateral displacement of the individual solar modules during assembly. The need to hold the solar modules manually until they are finally fastened by means of fixing screws is also dispensed with. When mounting on sloping roofs, it has proved to be advantageous to arrange the profile beams directly carrying the module composite in a ridge-parallel manner and to mount the individual solar module panels downwards starting from the ridge. For this purpose, for example, module clamps are attached to the profiled beams parallel to the ridge, which have a U-shaped cross section, wherein a clamping leg is bent outwards from the ends of the U legs, one of which extends over the ridge-side edge of a solar module and the other extends over the ridge-side edge of a further solar module. The bottom of the U has a dimension from leg to leg which is smaller than the width of the profile carrier and is designed wide enough to provide the head of the fixing screw with a hold between the legs, which is guided with its bolt through a corresponding bore in the bottom of the U and is screwed into a thread of the profile carrier. The U-legs each form a stop for the end face of a solar module. The solar module then rests with the underside on the profile support, with the end face on the stop of the module clamp, and with the upper face on the leg of the module clamp, at least with its edge region, which has an underside, an end face and an upper face, which leg presses on the upper face when the fixing screw is tightened, wherein the head of the fixing screw of the module clamp rests and the threaded bolt of the fixing screw is guided through the module clamp and screwed into the screw thread of the profile support.During assembly, the ridge-side edge region of the solar module is first pushed under the run-side leg of an upper module clamp which is mounted on the upper profile carrier. The ridge-side edge region of the solar module lies on the upper profile carrier. The front edge region of the solar module is then placed on the lower profile carrier and is still spaced apart from the stop of a lower module clamp mounted on the lower profile carrier to such an extent that the clamping leg of the lower module clamp does not yet engage over the upper side of the front edge region. This is only done in that the solar module slides against the stop of the lower module clamp in a gravity-assisted manner and is thereby spaced apart from the stop of the upper module clamp, but without coming out of the overlap by its upstream clamping limb or slipping off from the upper profile carrier. The solar module is thus floatingly laid.Due to wind load-induced movements of the entire roof over time, solar modules mounted in this way can undesirably move laterally out of their original position. In order to prevent this, on the one hand, the fixing screws of the module clamps are tightened in order to achieve clamping of the solar module edge regions, and on the other hand end caps are screwed laterally onto the ends of the profile beams, which end caps are usually made of metal in order to resist the lateral forces of the floating solar modules.In the case of all the advantages which the above-described or similar insertion system entails in the inclined roof mounting of solar modules, it is in the meantime problematic, owing to the increased dimensions of the solar modules compared to previously customary sizes, to tighten the fixing screws of the module clamps from above, since the solar modules can reach lengths along the roof inclination of up to 1.72 metres. Mounting persons standing below the mounting area on the sloping roof are therefore required to bridge distances of two metres and more manually and at the same time to exert pressure from above on the screw head to be tightened. This makes the assembly more time-consuming and thus more costly, but also unreliable if individual screws are not tightened with the correct torque because of poor accessibility, with the result that screwing together of the metallic end caps is considered to be necessary as an additional measure against lateral slipping of the solar modules.Against this background, the object to be achieved is to provide clamping holders which can replace the conventional module clamps of insertion systems for the inclined roof mounting of solar modules or, generally, plate-shaped components without losing functionality, can be fixed in a simple, accessible and more reliable manner and permit metallic end caps and their screw connection to be dispensed with.This object is achieved by a clamping holder according to claim 1, a mounting rail according to claim 9 and a mounting system according to claim 13, wherein advantageous embodiments result from the respective dependent claims.The proposed clamping holder has a web with an underside and a support leg with an inside, an outside and a free end, which is provided to be supported on a profile carrier, wherein the web has on the one end a clamping jaw with a clamping surface bounded by a terminal clamping front edge and on the other end a holding jaw with a contact surface bounded by a terminal holding front edge, between which the support leg and a tension connection are each arranged transversely to the underside of the web. The tension connection is positioned on the underside between the clamping jaw and the inner side of the support limb, has an end remote from the web and is operatively connected to an actuator arranged at least partially on the outer side of the support limb. Similar to the previously described module clamp with the U-shaped cross section having respective bent portions on the U-legs, in which the bent portion on the top side engages over the upper edge of a solar module and the bent portion on the top side engages over the lower edge thereof, this function is fulfilled here by the holding jaw and the clamping jaw. By actuating the actuator on the outer side of the support leg, the tension connection can be subjected to a tension force which moves the web and thus also the clamping jaw in the direction of the end remote from the web.In a simple embodiment, the tension connection can be, for example, a wire cable section which is fastened on one end side between the clamping jaw and the inner side of the support limb to the underside of the web and is anchored on the other end side to the actuator, which can be designed, for example, as a handle with latching notches, wherein the handle is guided completely or partially preferably by the half of the support limb which is farther from the web on the outer side thereof and can be fixed there by means of the latching notches in positions which project to different extents from the outer side. Of course, instead of notches, the handle can also have, for example, an external thread, by means of which the handle can be screwed into an internal thread of the support limb and can also be at least partially unscrewed again, in the opposite direction, in order to increase the tension on the wire cable section and to move the web and thus also the clamping jaws in the direction of the end remote from the web, wherein the actuator can also be designed as a threaded bolt with a bore for fastening the wire cable section on the inner side of the support limb and a screw head on the outer side of the support limb. During assembly, the support leg sits on the profile carrier and is preferably protected, for example by corresponding bent portions from the upper side of the profile carrier, from slipping off or lifting off from the upper side. A plate-shaped component can then be placed on the side of the clamping jaw on the profile carrier, wherein the contact surface is preferably bounded by a stop and the clamping surface engages over the plate-shaped component. The clamping holder is then still free on the side of the holding jaw and the actuator is not yet covered by a further plate-shaped component to be mounted. Thus, the actuator can be actuated during assembly, with the result that the web is subjected to tension via the tension connection and together with the web also the clamping surface of the clamping jaw is moved and thereby exerts pressure on the plate-shaped component overlapped by it.The pull connection is preferably designed as a claw, wherein the end of this claw remote from the web is part of an obtuse bend in the direction of the support angle, which is provided to be pulled closer to the carrier top side by means of the actuator against a flange projecting obliquely from the carrier top side. The claw is dimensioned such that, with the support leg placed on the profile carrier, it extends from the underside of the web of the clamping holder as far as the profile carrier and can thus slide with the obtuse bevel along a flange or even shoe arranged obliquely on the carrier upper side as soon as the claw is subjected to tension by means of the actuator. Apart from the obtuse bevel, the claw is preferably aligned approximately parallel to the supporting leg. If the claw is now pulled laterally on this part parallel to the support leg by means of an actuator, the tensile force is split into a first force vector, which runs in the direction of the direction of the pulling direction, i.e. laterally to the support leg, and a second force vector, which runs parallel to the support leg and ensures that the web and thus also the clamping jaw are pulled in the direction of the support surface, by sliding the obtuse bevel along a parallel oblique counterpart on the support top, preferably on an oblique flange or on the inner side of a shoe-like pocket structure.The connection of the tension connection to the web is preferably designed articulated, since in the case of a rigid connection or fastening, undesired material fatigue would have to be expected due to the tensile force acting. In the case of a tension connection configured as a cable cable section, the connection can be configured to be rotatable, at least pivotable in the case of a tension connection configured as a claw, wherein the pivot axis should preferably be oriented parallel to the clamping front edge.When the tension connection is designed as a claw, it is advantageous if the actuator has a threaded screw with a threaded bolt and a screw head. The screw head is here that part of the actuator which is positioned on the outer side of the support bracket. The threaded bolt is guided through the support bracket, preferably through a matching bore, in order to then be able to be turned into an inner winch of the claw. The internal thread is advantageously arranged in a molded part of the tension connection. In this case, the part of the claw which is approximately parallel to the support limb can be provided with an internal thread and therefore itself constitutes the shaped part, but it can also have, for example, a receptacle for a shaped part having the internal thread. It is advantageous if the molded part is the nut matching the threaded screw and is held in a rotationally fixed manner in a receptacle of the approximately support leg-parallel part of the claw, since threaded screws with matching nuts are produced in large quantities and are thus likely to be more advantageous in purchase than the costs for cutting a matching internal thread directly into the approximately support leg-parallel part of the claw.A similar embodiment, such as that in which the tension element is designed as a thread-carrying claw and the actuator is designed as a matching threaded screw, results if the screw head is not hexagonal, as is customary, but additionally or instead has a cam lever, such as in a quick-action clamping device, which are known to the person skilled in the art, for example, of bicycles of relatively high quality with a plug-in axle. This makes it possible to premount the clamping holder on the profile carriers in such a way that the relaxed quick-action clamping device, which projects with the cam lever at an angle from the outer side of the support limb, only has to be placed into the clamped state during the mounting on site, after positioning of the plate-shaped component, for example a solar module, between the clamping jaw of the clamping holder and the corresponding support of the profile carrier, by the cam lever being brought from its angular-projecting position into a position parallel to the outer side of the support limb, that is to say being folded, in order to apply the claw with the required tension, which brings about sufficient clamping of the plate-shaped component in order to prevent lateral movements of the component. The folding of the cam lever can be effected by means of a further plate-shaped component which is pushed between the retaining jaws of the clamping holder and the corresponding support of the profile carrier. The fixing of a plate-shaped component can thus be carried out in one operation with the positioning of an adjacent plate-shaped component between the retaining jaw and the corresponding support of the profile carrier. It is therefore advantageous to configure the screw head as a cam lever.In order to enable the support leg to be supported on the carrier surface in such a way that the support leg cannot slip, it is advantageous for the free end of the support leg to be part of a structure, such as a right-angled chamfer, for example, which points in the direction of the tension connection and is connected in a form-fitting manner to a formation of the carrier surface, for example a matching groove, for example the chamfer thus engages behind the groove. Thus, displacements in the direction of the tension connection can be prevented, while displacements in the opposite direction which go beyond the desired tension function are prevented, for example, by the flange for the obtuse beveling of the claw functioning as the tension connection.In order that a correct positioning of the plate-shaped components on the clamping jaw can be ensured in a simple manner, it is advantageous if the clamping surface, which is bounded on the one hand by the clamping front edge, is bounded on the other hand by a stop oriented orthogonally to the clamping surface, also referred to here as clamping jaw stop. On the side of the holding jaw, a leg oriented orthogonally to the contact surface, also referred to here as holding jaw leg, can analogously delimit the contact surface opposite the holding front edge. It is thereby expedient to form the retaining jaw limb as a section of the support limb.As already partially described above, at least one clamping holder interacts with a profile carrier which has a carrier top side. A profile carrier having at least one clamping holder is referred to here as a mounting rail, which is provided for plate-shaped components, such as solar modules, for example. The carrier top side of the mounting rail lies, at least in plan view, between two supports for the plate-shaped components arranged longitudinally along the profile carrier, on the one hand a support referred to here as a clamping support and on the other hand a support referred to here as a holding support. In this case, the clamping support and the holding support can be arranged next to the carrier top side without offset or else somewhat below the carrier top side on the respectively adjacent side surface of the profile carrier. The latter embodiment has the result that the side surfaces projecting beyond the supports can be used as stops. Therefore, the profile carrier should preferably have a box profile with a box-shaped base body. The support leg of the clamping holder is supported with its free end at least on the carrier top side and is advantageously releasably anchored to the latter. The clamping holder of the mounting rail is positioned such that the clamping surface of the clamping jaw partially covers the clamping support and the contact surface of the holding jaw at least partially covers the holding support. The tension connection is arranged completely or partially between the underside of the web of the clamping holder and the carrier top side. The clamping support, which interacts with the clamping holder, advantageously has a stop for the plate-shaped components. At least the clamping jaw stop should preferably be aligned with the corresponding stop of the clamping support on the profile carrier, since the plate-shaped component is in contact with the profile carrier in an insertion system for assembly with the first achievable stop when using the clamping holder, in order to be gripped as completely as possible by the clamping surface of the clamping jaw. It is therefore advantageous if these two stops are aligned with one another and thus both can be in contact with the plate-shaped component together. The situation is different for the retaining jaw leg, which can also be positioned further in the direction of the clamping jaw side of the web compared to the stop of the retaining support, since the plate-shaped component is only inserted into between the retaining jaw and the retaining support of the profile carrier, in order then to be spaced apart again a little from the stop of the retaining support when the same plate-shaped component is inserted between the clamping jaw and the clamping support. A stop on the holding support is not absolutely necessary, but has the advantage that the alignment of the profile carrier is possible on both sides if the clamping support and the holding support are each embodied with the stops in mirror image form with respect to one another.The mounting rail is advantageously pre-assembled in such a way that the support leg of the clamping holder is supported on the carrier top side and the traction connection, insofar as it is designed as a claw whose end remote from the web is, as described above, part of a blunt bent portion, partially covers a flange arranged obliquely on the carrier top side with the blunt bent portion. During the assembly of the plate-shaped components, complete overlapping of the flange can then take place. In addition, the pre-assembly of the mounting rail, insofar as it is present in the relevant embodiment, should also already take place so far that the structure which has the free end of the support leg and which points in the direction of the tension connection forms a positive fit with the corresponding formation on the carrier top side. If the clamping holder has a clamping jaw stop and a holding jaw leg, it is advantageous for the assembly system, which can be formed by means of the assembly rails, if the clamping front edge is arranged closer to the clamping jaw stop than the holding front edge on the holding jaw leg, since as a result, a plate-shaped component can be initially inserted between the holding jaws and the holding support and, nevertheless, a placement of the same component on the region of the clamping placement of the further profile carrier that is not covered by the clamping surface of a clamping holder arranged on a further profile carrier is possible.A mounting system can now be provided with a plurality of mounting rails, which mounting system has at least two mounting rails, namely at least a first and a second mounting rail, which are spaced apart from one another for the purpose of inserting plate-shaped components, in particular solar modules. In this case, the distance from a first boundary line between the clamping support of a first clamping holder and the carrier top side of the associated profile carrier of the first mounting rail to a second boundary line between the holding support of a second clamping holder and the carrier top side of the associated profile carrier of the second mounting rail should be the edge length of the respective plate-shaped component measured from the first in the direction of the second mounting rail plus the distance from the clamping front edge to the clamping jaw stop of one of the clamping holders.The mounting system may thus have a mounting state characterized by:a plate-shaped component, in particular a solar module, rests on the retaining support of the profile carrier of the second mounting rail.the plate-shaped component is covered by the contact surface of the second clamping holder.The plate-shaped component rests on the clamping support of the profile carrier of the first mounting rail.The plate-shaped component is not covered by the clamping surface of the first clamping holder.the tension connection of the first clamping holder is tension-free.In a final state, the mounting system deviates from the mounting state as follows:the plate-shaped component is spaced further from the retaining jaw limb of the second clamping holder than in the assembled state.the plate-shaped component is covered by the clamping surface of the first clamping holder.the tension connection of the first clamping holder is subjected to tension.The clamping surface of the first clamping holder presses the plate-shaped component onto the clamping support of the profile carrier of the first mounting rail.The mounting system is preferably to be mounted on surfaces which are part of an inclined or perpendicular plane and have a lower side and an upper side parallel to one another, such as for example on inclined roofs, in such a way that the mounting rails are arranged on the surface, wherein the profile beams are aligned parallel to one another and parallel to the lower and the upper side of the surface and the holding front edges of the clamping holders parallel to the profile beams face the lower side of the surface and the clamping front edges of the clamping holders parallel to the profile beams face the upper side of the surface. If the surface is an inclined roof, the profile beams are thus oriented parallel to the ridge and the holding front edges point in the direction of the ridge, while the clamping front edges point in the direction of the eaves. For example, plate-shaped components, such as solar modules, can be advantageously mounted from top to bottom. In this case, a suitably configured panel is first positioned and fixed along the uppermost profile carrier between the clamping jaw and the clamping support by actuating the parts of the actuators arranged on the outer sides of the support legs pointing in the direction of the eaves, preferably screw heads of threaded screws which act on tension connections configured as claws. Particularly preferably, the screw heads are designed as cam levers known from quick-action clamps, so that the actuation of the actuators can be effected by folding the cam levers projecting at an angle from the outer sides of the support legs by means of the upper edge of a solar module, which is pushed between the retaining jaw and the retaining support of the clamping holders with the panel to be fixed. As soon as the panel is fixed, the solar module can slide with its lower edge with gravity assistance between the clamping jaws and the clamping support of the next mounting rail. The fixing of the lower edge then takes place analogously to the fixing of the aperture. After the mounting of the lowermost solar module, a cover is again used, wherein here a fixing of the lowermost solar module by actuating the actuators must be ensured beforehand. Also conceivable are those lower panels which have a configuration by means of which the protruding pre-mounted cam levers can be folded against the outer sides of the supporting legs in a similar manner to the upper edges of the solar modules.It is optically advantageous to cover the lateral ends of the profile carriers of the assembly system with covers, wherein the covers, in contrast to the otherwise customary end caps, do not have to fulfil a static function and can therefore be manufactured cost-effectively from nonmetallic material and the profile carriers can be placed on in a manner facilitating assembly, merely in a friction-locking or latching manner, without further fastening means such as screws having to be used. During assembly, care must be taken to attach the covers before the upper edge of the subsequent solar module is inserted, so that work does not have to be carried out over already mounted solar modules, which would be significantly more complicated and difficult with the already mentioned increased dimensions of the solar modules.The clamping holder, the mounting rail and the mounting system are explained in more detail below by way of example with reference to drawings.Legend:1 Clamping holder 1 afirst clamping holder 1 bsecond clamping holder 2 plate-shaped components 3 web 4 underside of web 5 support leg 6 inside of support leg 7 outside of support leg 8 free end of support leg 9 profile carrier 9 aprofile carrier of first mounting rail 9 bprofile carrier of second mounting rail 10 clamping jaws 11 clamping front edge 12 clamping surface 12 aclamp surface of first clamping holder 13 holding jaws 14 holding front edge 15 contact surface 15 bcontact surface of second clamping holder 16 tension connection 16 a tension connection of first clamping holder 17 end of tension connection 18 actuator 19 obtuse beveling 20 carrier top side 20 acarrier top side of first mounting rail 20 bcarrier top side of second mounting rail 21 flange 22 molded piece 23 threaded screw 24 threaded bolt 25 26 Screw head 27 Structure 28 Formation 29 Clamping jaw stop 30 Holding jaw limb 30 b Halte jaw limb of the second clamping holder 31 Mounting rail 31 aFirst mounting rail 31 bSecond mounting rail 32 Clamping support 32 a Klemm support of the first mounting rail 33 Holding support 33 b Halte support of the second mounting rail 34 Box profile 35 Base body 36 Mounting system 37 First boundary line 38 Second boundary line 39 Profile carrier end M Mounting state E Final stateFig. 1 shows a preferred embodiment of the clamping bracket (1) from the side. The tension connection (16) is designed as a claw, which is oriented almost parallel to the support leg (5) and is attached to the underside (4) of the web (3) so as to be pivotable about the pivot axis (26). The web (3) has a clamping jaw (10) on one end with a clamping front edge (11), a clamping surface (12), which is plugged off here with thin auxiliary lines, and a clamping jaw stop (29) orthogonal to the clamping surface (12). On the other side, the web (3) has a holding jaw (13) with a holding front edge (14), a contact surface (15), which is likewise plugged off here by thin auxiliary lines, and a holding jaw leg (30), which is at least partially orthogonal to the contact surface (15), as part of the supporting leg (5). The support leg (5) serves as an abutment for the actuator (18), which is designed here as a threaded screw (23), the screw head (25) of which abuts the outer side (7) of the support leg (5). The threaded bolt (24) of the threaded bolt (23) is guided through the support leg (5) and engages in the shaped part (22), which has an internal thread (not shown here) matching the external thread of the threaded bolt (24). The shaped piece (22) is designed here as a nut which is mounted in a rotationally fixed manner in a receptacle of the tension connection (16) designed as a claw. In addition, a prestress is generated here around the threaded bolt (24) by means of a double conical helical spring (not numbered), said prestress spacing the tension connection (16) from the supporting limb (5) and simultaneously pressing the screw head (25) against the outer side (7) of the supporting limb (5). The traction connection (16), which is designed as a claw, has an end (17), which is remote from the web and is part of a blunt bent portion (19) of the traction connection (16). The bevel (19) is provided to cooperate with a flange (FIGS. 2, 21) on the carrier top side (FIGS. 2, 20) of a profile carrier (FIGS. 2, 9). FIG. 2 shows a preferred embodiment of a mounting rail (31) in side view, consisting of a clamping holder (1) and a profile carrier (9). The interaction of these two components of the mounting rail (31) takes place on the upper side (20) of the profile carrier (9), which here has a box profile (34), the carrier upper side (20) of which has a flange (21) projecting obliquely from the latter and a groove-shaped formation (28), the edge of the groove wall and the flange (21) pointing away from one another and being spaced apart from one another in a similar manner to the blunt chamfer (19) of the tension connection (16) from the structure (17) of the support limb (5) which has its free end (8). The structure (27) engages in the formation (28) and the obtuse bevel (19) abuts the flange (21) and can slide a certain distance along it. This occurs when the traction connection ( 16) is subjected to traction by means of the actuator (FIGS. 1, 18 ). As a result, the clamping jaw ( 10) approaches the clamping support ( 32) of the profile carrier ( 9) with the result that the clamping surface ( 12), here plugged off with thin auxiliary lines, presses on a plate-shaped component ( FIGS. 4 and 5, 2 ) arranged therebetween. In contrast to the clamping jaw (10), the holding jaw (13) with the contact surface (15), here likewise plugged off by means of thin auxiliary lines, remains unmoved, regardless of whether the tension connection (16) arranged between the underside (4) of the web (3) and the carrier top side (20) is tension-free or tension-loaded. The distance between the contact surface (15) and the holding support (33) of the profile carrier (9) thus remains the same. FIG. 3 again shows the mounting rail ( 31), this time obliquely from above. The two components of the mounting rail (31), namely the clamping holder (1) and the profile carrier (9), can be seen in turn. The profile carrier end ( 39) is to be seen in the foreground and is suitable for fastening a lateral aperture (not shown) to it in a frictionally locking or latching manner for optical reasons. The clamping holder ( 1) is placed on the base body ( 35) of the profile carrier ( 9). Space for plate-shaped components (FIGS. 4 and 5, 2), such as solar modules, is in each case between the clamping support (32) and the clamping jaw (10) and between the holding support (33) and the holding jaw (13), wherein the clamping jaws (10) and the holding jaws (13) are parts of the web (3). The clamping jaw (10) here has a clamping jaw stop (29). The parts of the clamping holder ( 1) already shown in FIG. 2 are depicted here in perspective, such as, for example, the screw head ( 25), the supporting leg ( 5), the tension connection ( 16), the blunt bent portion ( 19) and the flange ( 21). FIG. 4 shows the mounting system ( 36) in the mounting state (M), which has a first mounting rail ( 31 a) and a second mounting rail ( 31 b), between which a plate-shaped component ( 2), namely a solar module, is arranged, the full extent of which is illustrated here in a shortened manner, indicated by an oblique double line. The mounting system ( 36) is arranged here with the profile beams ( 9 a, 9 b) on an inclined roof (not shown), the surface of which is part of an inclined plane. Here, the first lower mounting rail (31a) is arranged closer to the eaves of the inclined roof than the second upper mounting rail (31b) is arranged closer to the ridge. In the mounting state (M) shown here, the solar module (2) is pushed as far as possible between the contact surface (15b) of the second clamping holder (1b) and the holding support (33b) of the profile carrier (9b) of the second mounting rail (31b), with the result that the solar module (2) rests on the tramp side of the clamping support (32a) of the profile carrier (9a) of the first mounting rail (31a), but is not covered by the clamping surface (12a) of the first clamping holder (1a). The first clamping surface (12a) is defined on the one hand by the clamping front edge (11) and on the other hand by the first boundary line (37) between the clamping support (32a) and the carrier top side (20a) of the profile carrier (9a) of the first mounting rail (31a) in terms of its extent, while this is effected on the second contact surface (15b) on the one hand by the holding front edge (14) and on the other hand by the second boundary line (38) between the holding support (33b) and the carrier top side (20b) of the profile carrier (9b) of the second mounting rail (31b). The tension connection ( 16 a) of the first clamping holder ( 1 a) is thereby tension-free. The solar module ( 2) is spaced apart from the clamping jaw stop ( 29) of the first clamping holder ( 1 a). FIG. 5 shows the mounting system ( 36) in the final state (E). In contrast to the assembled state (FIG. 4, M), the plate-shaped component ( 2), here a solar module, lies here completely on the clamping support ( 32 a) of the first mounting rail ( 31 a) and is pressed by the entire clamping surface ( 12 a) of the first clamping holder ( 1 a) onto the clamping support ( 32 a) of the first mounting rail ( 31 a), since the first tension connection ( 16 a) is tensioned here. On the ridge side, the solar module (2) nevertheless lies on the second holding support (33b) and is partially still covered by the second contact surface (15b) of the second clamping holder (1b). The solar module is thus protected, on the one hand, from lifting off due to wind forces or falling downwards onto the roof surface. Undesired lateral movements of the solar module ( 2) are prevented by the clamping between the first clamping surface ( 12 a) and the first clamping support ( 32 a). Otherwise, this figure shows further features of the mounting rails (31) constituting the mounting system (36), namely the first, upstream mounting rail (31a) and the second, first mounting rail (31b), namely the first boundary line (37), the second boundary line (38), the holding front edge (14), the clamping front edge (11), the clamping jaw stop (29) of the first clamping holder (1a), the profile carrier (9a) of the first mounting rail (31a) with the first carrier surface (20a) and the profile carrier (9b) of the second mounting rail (31b) with the second carrier surface (20b). The solar module ( 2) abuts the clamping jaw stop ( 29) of the first clamping holder ( 1 a).
