Description

The subject matter of the invention is a roof construction with at least two panel supports for supporting self-supporting panels, for example insulating panels, underneath a roof covering which is profiled in cross-section, for example corrugated, which in turn is part of the roof construction.

Roof coverings profiled in the transverse direction, for example corrugated sheet metal or roof coverings made from other materials with such a shape or also trapezoidal sheets, are used in the same way as other roof coverings profiled in the transverse direction in connection with inexpensive roof constructions. Such roof constructions are found, for example, in hall construction or in buildings erected in the agricultural sector, such as stables, barns and the like. Such roof coverings are transversely profiled by an alternation of support sections supported directly or indirectly on purlins and by high sections located between each two support sections. The high sections are not supported on the purlins of the roof structure being spaced from them. However, the high sections can be used to fasten such a roof covering to the purlins, for example by means of screws, which is also possible in the support sections.

If, in addition to such a roof covering, insulation is required as part of the roof construction, it is placed below the purlins and, if present, the rafters. The reason for fastening is the purlins or rafters, to which insulating panels are connected using screw fasteners. The assembly of such insulation is complicated, since such an insulating panel must be placed in the desired fastening position on the supporting structure of the roof—the rafters or purlins—and screwed to it in this position. At least two, typically even more than two people are required for this.

According to another embodiment of an insulated roof for such buildings, self-supporting sandwich panels are used as finished insulation panels. The outer sandwich layer is typically made of metal and profiled in the transverse direction. A rigid insulating compound is adhesively connected to this outer sandwich layer. The underside of such a panel is in turn formed by a generally unstructured plate. An assembly of such an already insulated roof covering takes place from the outside and is therefore easier in terms of assembly than the subsequent installation of under-roof insulation, as described above, in which insulating panels have to be fastened to the roof structure from below. The problem with such a roof construction is that the roof has to be opened from the outside for repair work.

Proceeding from this discussed state of the art, the invention is based on the object of proposing a roof construction in which the installation of under-roof insulation, ie panels to be attached underneath a profiled roof covering, is simplified.

• Einen Tragarm mit einem oberen Ende und einem unteren Ende und
• ein Tragmittel an dem unteren Ende des Tragarms, die in zumindest einer Querrichtung (x-Richtung und/oder y-Richtung) von dem Tragarm abragt und deren zu dem oberen Ende des Tragarms weisende Seite ein Auflager zum Tragen einer Paneele ist,

wobei die Tragmittel der Paneelträger unterhalb der Pfetten befindlich sind und ein selbsttragendes Paneel auf die Tragplatten mehrerer Paneelträger aufgelegt ist.This problem is solved by a roof construction with panel supports for supporting self-supporting panels underneath a roof covering as part of the roof construction, which roof covering is profiled in its transverse direction (y-direction), in which roof construction the roof covering is attached to purlins extending in the transverse direction (in y-direction) extend to the longitudinal extent of its profile, which profile of the roof covering is formed by an alternation of support sections supported on the purlins and high sections, which high sections of the roof covering together with the side of a purlin pointing to the roof covering in the longitudinal extent of the profile (x -direction) form open hollow chambers, which panel supports include the following elements:

• A support arm having an upper end and a lower end and
• a support means at the lower end of the support arm, in at least one transverse direction (x-direction and / or y-direction) of protrudes from the support arm and whose side facing the upper end of the support arm is a support for supporting a panel,

wherein the support means of the panel girders are located below the purlins and a self-supporting panel is placed on the supporting plates of a plurality of panel girders.

To solve the problem arising from the prior art, a roof construction with panel supports as mounting means for holding or supporting self-supporting panels below the roof covering and thus below the roof substructures formed by purlins and, if present, the rafters is proposed. Such a panel support is characterized in that it provides a support means arranged below the purlins or the rafters, on the upper side of which, i.e. the side that faces the roof covering or the upper end of the support arm, a self-supporting panel can be placed . Such a support means can be a support plate which, in the narrower sense, has a plate-like extension. However, this term also includes those suspension means that have a support for at least one self-supporting panel. These support means can be, for example, a support profile, typically extruded, which has one or two legs following its longitudinal extension and protruding from a central section. In such a configuration, the legs represent the support legs. Such a support means is typically designed to be connected to the support arm of a panel support. Typically, four panel supports are used to support such a panel, the panel supports with their support arms typically being arranged at least in the corner areas of the panels. In the concept according to the invention, the panel supports are first brought into position with their support plates, and are therefore attached to the roof substructure. The panels are then placed on the tops of the support plates, each of which forms a support for such a panel. Both the attachment of the panel support and the subsequent placement of the panel or panels can be carried out by a single person.

Such a panel carrier has a support arm, the longitudinal extent of which follows the direction of the height of the roof structure, typically a purlin. The support arm of such a panel support has connecting means for connecting it to the substructure, typically a purlin, of the roof structure. The carrying means already mentioned is located at the lower end of the carrying arm. This protrudes from the support arm in at least one transverse direction (transverse direction in relation to the longitudinal extent of the support arm; x-direction and/or y-direction). These areas of the support means that protrude over the support arm of the panel support form the support for one or more self-supporting panels.

The term self-supporting panels used in this embodiment includes all plate-like objects that are self-supporting due to their material properties and/or their design, for example if they are designed in multiple layers, and are therefore dimensionally stable without additional stiffening means.

The panel supports of the roof construction thus serve to provide a support for self-supporting panels, for example insulating panels, to be attached underneath the roofing, as these are known per se. The panels are thus supported by the support formed by the support means of the panel supports. The provision of panel supports makes it considerably easier to install such panels under the roof. In a first step, the panel supports are attached to the roof construction. The support means of the panel supports are spaced apart from one another in at least one direction, specifically at such a distance that a panel can be inserted between two support means and placed on top of the support means. An installation of under-roof insulation can thus be carried out by a single person using these panel supports.

Since the panels are only placed on the support means serving as a support after the panel carrier has been installed, a subsequent Such a panel can easily be exchanged for another. At the same time, access to the underside of the roof covering can easily be provided in this way, should this be necessary for repair work, for example, without having to open the roof from the outside. If desired, the panels placed on the support means can also be fixed with fasteners.

The self-supporting panels to be arranged or arranged on the suspension means can be panels that provide a decorative surface on their underside. It can also be insulating panels that achieve thermal and/or acoustic insulation. Such panels and/or the support plate of such a panel support can be equipped with additional components or designed to accommodate additional components. Such additional components can be lighting inserts, for example. According to one embodiment, in such a case such a self-supporting panel or also the panel support has a corresponding recess into which a lamp insert can be inserted on the underside.

The spacing of the insulation from the underside of the roof covering also ensures the necessary rear ventilation.

In a first embodiment, the support arm can be connected to the roof structure, typically a purlin, by means of screw fasteners.

In a preferred embodiment, a hook element is connected to the upper end of the support arm, which protrudes from the support arm in the direction of the longitudinal extension of the profile of the roof covering (in the x-direction). This hook element is intended to engage in a hollow chamber formed by a high section of the profiled roof covering of the roof construction with the upper side of the purlin. The hook element is held within such a hollow chamber provided by the roof construction by a pretension acting on the inner wall of the hollow chamber through the outside of the hook element. The hook element is thus in a position provided by the roof construction Hollow chamber held frictionally in the longitudinal direction of the profiling (x-direction) of the roof covering. The hook element as a connecting element for connecting the panel carrier to the roof structure is designed with regard to its shape in such a way that it is typically accommodated without play in the transverse direction (y-direction) in such a hollow chamber. The assembly of such a panel support is very simple. All that is required for this is that its hook element is pushed into such a hollow chamber provided by the roof construction. The use of fasteners and the carrying of additional tools and fasteners to attach the panel supports and the entire sub-roof insulation is not necessary with this panel support.

The prestress required for such a design of a panel support typically results from the material properties of the hook element itself. Typically, a plastic material such as a thermoplastic material, such as polyamide (PA), polyvinyl chloride, is used to form the hook element and the support arm typically molded onto it as an integral part (PVC), polyurethane (PU), polypropylene (PP) or any other thermoplastic polymer or block copolymer. The material properties are designed either through the design of the geometry of the hook element (material quality, material thickness and the like) or through the reinforcement elements incorporated therein, so that it can absorb the forces and exert the desired prestress for fixing such a panel support to the roof structure.

The deformability of the hook element can be provided by the compressibility of the material of the hook element. In a preferred embodiment, the prestressing is achieved by the provision of two deformable clamping arms which, in their non-use position in which the hook element is not yet inserted into a hollow chamber of a roof structure, are oversized in terms of hollow cross-sectional area. In this exemplary embodiment, the prestressing results from the elastic deformation of these clamping arms when the hook section is inserted into such a hollow chamber. the Depending on their design, clamping arms then act in a direction transverse to the longitudinal axis of the profile and thus in the y-direction and/or in the z-direction or with a corresponding vectorial component in these directions against the underside of the roof covering. The oversize of the clamping arms in the direction of their elastic adjustability depends on the desired force to be applied by the prestressing and can, for example, be 2 to 20% greater in the direction of adjustability than the relevant free cross-sectional area of the hollow chamber geometry. In this exemplary embodiment, the elastic adjustability of the clamping arms is based on the elasticity of the material used. It is also quite possible that the oversizing of the hook element to provide the desired frictional connection when inserted into a hollow chamber of the roof construction can be less than 2%. An oversizing of 0.5% can already be sufficient. It is also possible that the clamping arms act against a spring element. With such an arrangement, the clamp arms themselves can be rigid.

In order to make it easier to insert such a hook element into a hollow chamber, a preferred embodiment provides that the radial lateral surface of such a hook element is tapered in the direction of its front side pointing away from the support arm, specifically at least in the sections which are oversized compared to the cross-sectional area of the hollow space and which are elastic to be adjusted or deformed. In such a configuration, the area of the front side of the hook element is somewhat smaller than the clear width of such a hollow chamber in this regard. Such a tapering acts as an adjusting bevel, so that when the hook section is pushed into the cavity, the clamping arms are automatically adjusted.

The clamping arms typically extend over the entire length of the hook element (x-direction). The two clamping arms typically run parallel to one another and are spaced apart from one another by a gap at their free ends. The gap width is sufficiently large so that the desired adjustability is possible and the clamping arms can be guided past fasteners, through which the roof covering is fastened to a purlin in the area of its high sections, typically in the area of its apex in the case of a corrugated profile, by means of fasteners.

According to one exemplary embodiment, the support arm is a plate-shaped element that carries the support means at its lower end. The support means can be an integral part of the support arm, ie it can be made in one piece with it. In another embodiment, it is provided that the support means are engaged with the support arm by mechanical connecting means, specifically in a form-fitting manner in the direction of the longitudinal extension of the support arm (z-direction).

Such a form fit between the support arm and its support means can be achieved, for example, in that an undercut groove is introduced into the side of the support arm pointing downwards. With regard to the cross-sectional geometry, the suspension element carries a complementary connecting web. In this case, the support arm has a female connector contour and the support means has a male connector contour. It goes without saying that the connector contours can also be exchanged, so that the support arm has a male connector contour and the support means has a female connector contour. The cross-sectional geometry of these connector contours is T-shaped, for example, but can have any cross-sectional geometries, with the undercut of the groove and the formation of the complementary connecting web preferably being undercut on both sides, as is the case with a T-shaped configuration.

In one exemplary embodiment, it is provided that with such a design of the support arm and support means, the support means is a support plate with a connecting web that carries the connecting means for connecting the support plate to the support arm.

The support means can also be connected to the support arm in a different way, for example with a hook system. In a further development of such a hook-like or claw-like engagement position of the support arm and Support means is provided that the support means carries a hook, which engages with the free end of its hook portion with a precise fit in a corresponding receptacle of the complementary hook assigned to the support arm or a hook receptacle. In this way, an undesired pivotability of such a suspension element, designed for example as a profile, in the x-direction is prevented. Such a hook connection can also be designed in a latching manner, through which latching a user receives haptic feedback when the carrying means is mounted on the carrying arm as intended. It is also entirely possible to design the support means so that they are molded onto the support arm and then connected to a connecting element for connecting the panel support to the roof structure, for example the hook element, by means of a mechanical connection, for example a hook system. It is also entirely possible to use different connection systems between the support means and the respective support arms in a roof construction. For example, it may be advisable to basically connect the support means to the support arms with complementary connector contours and to connect support means that are mounted last to the respective support arm with hook connectors, for example.

The support arm can have one or more feed-through channels following its width (y-direction). These can be used for the passage of electrical cables, so that no additional brackets are required if electrical cables are to be laid outside of the panels to be supported.

The support arm can be designed in one piece. An embodiment in which the support arm is composed of two or more support arm parts is also entirely possible. A combination of two or more support arm parts enables the length of the support arm to be adjusted to that required in the application. For example, an adjustment of the length of a support arm may be necessary if the roof construction has, in addition to the purlins, also rafters running transversely thereto and consequently the panels to be arranged are to lie below the rafters. same for also for purlins of different thicknesses, since these have a different thickness (height) depending on the size of the roof construction. Such support arm parts can preferably be connected to one another in the same way as is described above for the connection of the support arm to a support means. The connector contours are expediently identical, so that a second support arm part or a support means can optionally be connected to the lower end of a support arm as the first support means.

The support arm and the support means of such a panel support can be made of the same material as those described above for the hook elements.

If two panel supports arranged at a distance from one another are attached to one purlin or to two adjacent purlins, the support arms of these panel supports can be connected by an additional support. This achieves a certain degree of reinforcement of the panel support structure. Such an additional support is of particular advantage if it is H-shaped, with the openings following the longitudinal extent of the profile pointing in the transverse direction of the profile (x-direction) and thus in the direction of the profiling of the roof covering. This geometry of the additional carrier not only causes it to be stiffened. Rather, the open U-shaped receptacles can be used to insert an edge section of a panel therein. In this way, the side surfaces of such a panel that engage therein are at the same time protected against the effects of moisture, for example. Typically, the side legs enclosing such an opening have inwardly protruding barb-like elements that make it difficult to pull out the edge section of a panel inserted therein.

As already mentioned above, a support profile can also serve as the support means. According to one embodiment, this is an extruded profile. According to one embodiment, such a profile has a central section. This is the section on which the mechanical connection means, for example a hook, is formed. from Projecting from the central section, depending on the design of the support means, support legs are provided on one or both sides as a support for a self-supporting panel. The central section can be equipped with a mounting channel that follows the longitudinal extent of the support profile. The assembly channel can be used for wiring or for the installation of electrical/electronic components, such as the accommodation of lighting. Such a mounting channel can also be used to connect additional elements that protrude from the underside of the support means, such as pendant lights or the like. For the assembly of such objects or also for the integration of lighting, the wall of the assembly channel is preferably equipped with clamping structures, for example protruding ribs, to which objects to be assembled can be fixed, for example by a snap-in connection. Stiffening profile segments can also be located in the mounting channel. With such a support means, projections can be formed on the profile walls delimiting the supports for a self-supporting panel, which are located at a certain distance from the support surface of the support legs. This creates a receptacle in which an object inserted therein, for example a self-supporting panel or a panel connection profile, engages with its end section and is held therein in a form-fitting manner in the z-direction. In this way, a panel resting on or supported by such a support leg is secured against being lifted by drafts or wind.

In addition to the roof construction described above, one aspect of the invention is also a panel support, as described in the context of this embodiment, even without the associated roof construction.

In the exemplary embodiment illustrated in the figures, a panel support 1 comprises a support arm 2, at the upper end of which a hook element 3 is connected as a head part for connecting the panel support 1 to a roof structure. The hook element 3 has been manufactured in one piece with the support arm 2 . The support arm 2 is a plate-shaped element whose height in the z-direction, its width in the y-direction and its Material thickness runs in the x-direction. A feed-through channel 4 is introduced into the support arm 2 . The longitudinal extension of the feed-through channel 4 follows the width and thus the y-extension of the support arm 2. The feed-through channel 4 can be used to feed electrical lines, for example.

At the lower end of the support arm 2, a support plate 5 is connected as a support means. The support plate 5 protrudes over the width and the transverse direction of the support arm 2 and thus in the x-direction and y-direction over it. The support plate 5 is connected to the support arm 2 by means of connector contours 6, 7 which are designed to complement one another and engage with one another. in the illustrated embodiment in cross-section T-shaped groove 8 as female connector contour 6. The support plate 5 carries a top side as a complementary male connector contour 7 a connecting web 9. The connecting web 9 is designed in cross-section complementary T-shaped. In the exemplary embodiment shown, it is provided that the two connector contours 6 , 7 are engaged with one another by pushing the connecting web 9 into the undercut groove 8 . Due to the double-sided undercut, T-shaped contour of the mutually engaged connector contours 6, 7, these have a form-fitting effect in the direction of the height of the support arm 2 (in the z-direction). In the figure 1 The support plate 5 shown has a tongue 10 on its narrow side. A support plate adjoining it, held by a second panel support, has on its complementary end face a groove designed to complement the tongue 10, so that two support plates adjoining the end faces in the y-direction are connected by a tongue and groove -connection can be engaged with each other.

The hook element 3 arranged at the upper end of the support arm 2 is designed to be inserted into a hollow chamber 24 of a roof structure 17 . The hook element 3 has two clamping arms 11, 11.1 (see also figure 3 ). The contour of the outside of the clamping arms 11, 11.1 is adapted to the contour of such a hollow chamber 24. The two Clamping arms 11, 11.1 are separated from one another by a gap 12. The hook element 3 protrudes from the support arm 2 in the x-direction and engages with this section in a hollow chamber of the roof construction, as is described in more detail below, when connected to a roof construction. The front side 13 of the hook element 3 protruding from the support arm 2 in the x-direction is tapered, as shown in figure 2 is recognizable. The tapering is identified therein by the reference numeral 14 and is limited to that area of the hook element 3 which is oversized compared to the clear width of a hollow chamber (see explanations below).

Each clamping arm 11, 11.1 comprises a clamping section 15 (see figure 3 ) and a clamp arm base 16. The clamp arms 11, 11.1 are elastically deformable, as shown in figure 3 indicated by the arrows, namely in its clamping section 15. The clamping arm base 16, on which the respective clamping arm section 15 is formed, is stiffer than the respective clamping section 15 and therefore does not react to a deformation of the respective clamping section 15 in the x and y directions .

The support arm 2 and its hook element 3 are made of a plastic that can withstand the required load-bearing forces, namely a polyurethane in the exemplary embodiment shown. The elastic deformability of the clamping arms 11, 11.1 results from the figure 3 recognizable cross-sectional geometry and the properties of the material used.

figure 4 shows a roof construction 17. The roof construction 17 comprises a roof covering 18 which is profiled in a wavy manner in the transverse direction (y-direction) in the manner of corrugated sheet metal. The structures of the profiling extend in the x-direction. The roof covering 18 is supported on a substructure 19 . In the illustrated embodiment, the substructure 19 consists only of horizontally running purlins arranged at a distance from one another, of which figure 4 a purlin 20 is shown. The roof covering 18 is fastened to the purlin 20 by means of fasteners 21 .

The wavy profile of the roof covering 18 is formed from an alternation of support sections 22 and high sections 23 located between two support sections 22 in each case. The support sections 22 are supported on top of the purlin 20 . In the illustrated embodiment, the fasteners 21 pass through the crests of the risers 23 to connect the roof covering 18 to the purlin 20.

In the figure 4 The roof structure shown is, for example, one of a stable or a barn.

In order to insulate the roof structure 17, insulation is installed underneath it. Several or a large number of panel supports 1 are used for this. Each panel support is inserted with its hook element 13 into a hollow chamber 24 provided by the roof construction 17 (see Figures 5 and 6 ). Such a hollow chamber 24 is provided by the undersides of the raised sections 23 of the roof covering 18 and the upper side of the purlin 20. The dimensioning of the hook element 3 of such a panel support 1 is oversized in relation to the clear width provided by a hollow chamber 24, namely in relation to its elastically deformable clamping arms 11, 11.1 or their clamping sections 15. The relevant oversizing is in figure 5 shown. In contrast, the cross-sectional area of the front side 13 has such a cross-sectional geometry that it fits into a hollow chamber 24 . When such a panel support 1 is installed, the taper 14 thus serves as an adjusting bevel in order to insert the hook element 3 into a hollow chamber 24 . In the course of this insertion, the clamping sections 15 of the clamping arms 11, 11.1 are moved toward one another and in the direction of the respective clamping arm base 16. This mobility is in figure 3 indicated by arrows. figure 6 shows the panel support 1 connected to the roof structure 17 looking towards the front side 13 of the hook element 3. The hook section 3 of the panel support 1 inserted into the hollow chamber 24 acts by the elastic restoring force in its clamping sections 15 against the inner contour of the high section 23 of the roof covering 18. The Clamping effect in the illustrated Embodiment acts primarily in the z-direction. In this way, such a panel support 1 is connected to the roof structure 17 in a frictionally engaged manner in the x-direction. If the hook element 3 is inserted into a hollow chamber 24 and acts with its clamping arms 11 , 11 . In the direction transverse to the longitudinal extent of the hollow chamber 24, as shown in FIG Figures 5 and 6 recognizable, the hook section 3 was received in a form-fitting manner within such a hollow chamber 24 .

figure 6 shows the panel support 1 connected to the roof structure 17, on the support plate 5 of which a self-supporting insulating panel 26 is placed. The insulating panel 26 of the exemplary embodiment shown is a commercially available insulating panel, for example with a core made of rigid polyurethane foam or rigid polyisocyanurate foam, which is laminated on both sides with a gas-tight aluminum layer.

For a better visualization of the arrangement of the insulating panel 26 on the support plate 5 of the panel support 1, this support arrangement is shown without a roof structure figure 7 shown.

The longitudinal extent of such an insulating panel (extension in the y-direction) is generally significantly longer than the corresponding extent of a support plate 5. Such a panel 26 is therefore typically supported on a purlin by at least two or more panel supports 1. It goes without saying that further panel carriers are connected in the same way to another purlin spaced apart from the purlin 20 in the x-direction, on whose supporting plates the panel 26 is placed with its other end region and is thus supported by these supporting plates.

To protect the side surfaces of two adjacent insulating panels 26, these can be connected to one another by an H-shaped profiled connecting profile 27, as is shown schematically in FIG figure 8 is shown. The edge of such a panel 26, 26.1 is inserted into the opposing receptacles 28, 28.1. The recording 28, 28.1 forming On the inside, legs carry barb elements 29, 29.1 that are elastically adjustable in the direction of the depth of such a receptacle 28, 28.1 (marked with reference numbers only for the receptacle 28), so that a panel 26, 26 inserted into such a receptacle 28, 28.1 is held there against being pulled out is.

Such a connector profile 27 can be used as a carrier in that it is connected to two support arms 2 arranged adjacent to one another, each of a panel carrier 1 . The construction of the panel support 1 can be reinforced by such a measure.

In an embodiment of a support plate of such a panel support, not shown in the figures, it is provided that this has a recess on the underside that follows its longitudinal extension (y-direction). If desired, such a recess serves to accommodate additional functional components, such as lighting inserts, such as LED lighting. Such a lighting insert comprises a multiplicity of light sources arranged in the manner of a grid. In this way, such a panel support 1 can be used at the same time, for example to integrate lighting into its support plate. Cabling can be done on the upper side, for example also using the feed-through channels 4 present in the support arms 2 of the panel carrier 1. The self-supporting panels can also be used for this purpose in a corresponding manner, which then have such a receptacle on the underside. The fact that the panels can be handled even after they have been installed also allows such a lighting device to be retrofitted as an example of a functional component. If no functional module is to be integrated when such support plates or panels are used, the receptacle can be closed with a cover. If additional components are to be installed, these can of course also be mounted as add-on modules on the underside of such a panel. The advantages with regard to cabling that may be required on the upper side can also be used with such a design.

figure 9 shows another panel carrier 1.1 for or as part of a roof construction, as has been described in the preceding figures. The panel carrier 1.1 comprises a hook element 3.1, which corresponds to that of the exemplary embodiment in the preceding figures and thus to the hook element 3. The relevant statements thus apply equally to the hook element 3.1. Molded onto the hook element 3.1 is a support arm 2.1. The support arm 2.1 of the illustrated embodiment extends in the z-direction. The support arm 2.1 has a hook receptacle 30 on the underside for connecting a support means. The hook receptacle 30 has a receptacle extension 31 through which the hook receptacle 30 is located in that area in which the free end of a complementary hook of the suspension element is arranged. A support profile 32 is connected to the panel support 1.1 as a support means via the hook receptacle 30 in the exemplary embodiment shown. In the exemplary embodiment shown, the support profile 32 is an extruded aluminum profile made from an aluminum alloy suitable for this purpose. The support profile 32 comprises a central section 33. The central section 33 is designed to be approximately U-shaped in terms of profiling, with the opening pointing downwards. Two support legs 35, 35.1 are formed on the legs 34, 34.1, projecting outwards and thus in the y-direction. The upper side of the supporting legs 35, 35.1 forms the support for the panels to be supported by the panel carrier 1.1. Such a self-supporting panel 36 is shown as an example on the supporting leg 35 .

A hook 37 is formed on the central section 33 for connecting the support profile 32 to the support arm 2.1 of a panel support 1.1. The hook 37 is designed to complement the hook or the hook receptacle 30 of the support arm 2.1. The free end of the hook element of the hook 37 dips into the receiving extension 31 of the hook receptacle 30 . In the illustrated embodiment, the connection of the support profile 32 to the support arm 2.1 is secured by a latch. For this purpose, there is a locking projection 38 on the upper side of the support profile 32, which engages in a complementary locking groove in the area of the lower end of the support arm 2.1 of the panel support 1.1.

The hollow space formed by the U-shaped design of the support profile 32 represents a mounting channel 39. This can be used for different purposes. For example, the mounting channel 39 can be used as a cable routing channel. In addition to or instead of using the mounting channel 39 in this way, there is also the possibility of using it to connect objects protruding from the support profile 32 . These can be lamps, for example. Lamps in the form of light strips can also be mounted inside the mounting channel 39. For the purpose of clamping objects to be inserted in the assembly channel 39, there are projecting clamping ribs on the sides of the legs 34, 34.1 which point towards one another. These can also be used to close the lower opening of the mounting channel 39 with a cover part.

The support profile 32 is connected to the roof structure with several panel supports 2.1.

A holding leg 40, 40.1 is located on the outside of each leg 34, 34.1. In this exemplary embodiment, the retaining legs 40, 40.1 extend parallel to the respective support legs 35 or 35.1. Thus, each supporting leg 35 or 35.1 and the holding leg 40 or 40.1 associated therewith provide a receptacle open in the y-direction. This can be used to insert the edge area of a panel or a connector profile 41 with its end section. Such a connector profile 41 is in figure 9 shown embodiment used in the supporting leg 35 associated with this recording. The longitudinal extension of the connector profile 41 runs in the y-direction. The connector profile 41 is a double-T connector into which adjacent panels 36 engage with an edge section. In this way, the panel 36 and the adjacent panels in the x-direction are secured against undesired lifting, for example caused by wind suction. At the in figure 9 In the exemplary embodiment shown, this securing takes place via the engagement of the panel connector 41 in this securing recess.

The support profile 32 is designed asymmetrically with respect to the alignment of the walls enclosing the mounting channel 39 . This has the advantage that in order to cover the upper side facing the support arm 2.1 with a panel, only one of the two panels to be supported by the support profile 32, here: the panel 36, has to have a corresponding cutout. The representation in the figure 9 makes it clear that a panel to be positioned on the supporting leg 35.1 does not have to have such a cutout as is required for the panel 36 for overlapping the profile sections enclosing the mounting channel 39.

figure 10 shows another support profile 32.1, which corresponds in principle to the support profile 32. In the case of the support profile 32.1, one support leg 35.2 is angled relative to the other support leg. The same applies to the holding leg 40.2 assigned to it. By using such a support profile 32.1, changes in the inclination of the roof structure can be compensated. It is understood that instead of the in figure 10 shown angle between the support legs such a support profile can also have a different angular arrangement of its legs to each other. A typical use of such support profiles 32.1 is also the area of the roof construction below the ridge.

The invention is described with reference to the figures using exemplary embodiments. Without departing from the scope of the applicable claims, a person skilled in the art will have numerous further implementation options without having to explain them in detail within the scope of these statements. <b>Reference List</b> 1, 1.1 panel support 33 central section 2, 2.1 Beam 34, 34.1 leg 3, 3.1 hook element 35, 35.1, 35.2 carrying leg 4 conduction channel 36 panel 5 support plate 38 rest extension 6 connector contour 39 mounting channel 7 connector contour 40, 40.1, 40.2 holding leg 8th groove 41 panel connector 9 connecting bridge 10 feather 11, 11.1 clamping arm 12 gap 13 front 14 rejuvenation 15 clamping section 16 clamp arm base 17 roof construction 18 roof covering 19 substructure 20 purlin 21 fastener 22 support section 23 high section 24 hollow chamber 25 front 26, 26.1 insulating panel 27 H-shaped connector profile 28, 28.1 admission 29, 29.1 barb element 30 hook pickup 31 recording extension 32, 32.1 support profile
