Description

The invention relates to a support device for a wall or ceiling covering with supports that can be attached to the wall or ceiling at a lateral spacing and supporting elements attached thereto for a lower plate edge of a wall or ceiling covering plate that runs perpendicular to the longitudinal axis of the support, and holding elements for a parallel, in particular upper plate edge, the holding elements, at least are essentially held immovably on their carrier or are fastened to it and each support element is held in a displaceably fixed manner on its carrier at a distance corresponding to the plate height from its element associated with its holding element associated with the same plate, and each plate is assigned at least two parallel carriers. The brackets can be attached directly or indirectly to the wall or ceiling. For direct installation, for example, dowels and screws are suitable. The addressed, in particular lower, plate edge, which runs perpendicular to the longitudinal axis of the beam, of course also extends approximately parallel to the wall or ceiling. "Lower" refers to a wall covering and the same applies to the "upper panel edge" mentioned. In the case of ceiling mounting, one could speak of a front and rear panel edge. For the sake of simplicity, only the wall cladding is considered below in order to avoid misunderstandings, but this is in no way intended to be restrictive and should not be interpreted in this way.

Analogously, "panel height" means the height of a cladding panel measured in the vertical direction. The plate length therefore extends in the horizontal direction if rectangular plates are placed underneath, which corresponds to a normal version. At least two parallel supports are assigned to each plate. These run in a vertical direction during wall mounting. They are usually assigned to the lateral longitudinal areas of the plate. There are also two such parallel vertical beams several plates or plate pairs arranged one above the other attached. Furthermore, it is assumed in the entire IP documents that one and the same support serves to support, for example, the left edge of a plate and the associated right edge of a plate attached laterally next to it. Instead, such a carrier could also be divided lengthways, in which case its individual halves are then screwed on separately, but this is not normally justifiable for reasons of expediency, in particular also for reasons of cost. This aspect is also to be understood as the training according to the invention, insofar as it relates to its holding grooves.

In a known carrying device of this type, relatively simple support and holding elements are used, which basically form lower and upper hooks. Each plate is supported at its lower edge in two such hooks, which each encompass the lower plate area. In the same way, the upper edge of the plate is encompassed by two such hooks, for example. A fastening leg, which expediently extends transversely to the plane of the plate, serves to fasten these hooks to the carrier. If we are talking about two upper and lower hooks, it was assumed that each plate is held on two parallel supports. If a third support is assigned to the middle panel area, three upper and three lower hooks are of course used.

Each of the hooks is attached to the carrier with two fastening elements. With at least four required hooks, this means eight fastening points, the hooks being pre-punched, but the brackets must be punched accordingly. In addition, eight fasteners, such as rivets, screws and the like. needed. In addition, these hooks are only suitable for a very specific plate thickness and an adaptation to a different plate thickness is at least not possible with simple means.

The object of the invention is therefore to develop a device of the type mentioned in such a way that the assembly effort, in particular in terms of time, can be reduced. This inevitably also reduces the installation costs for the suspended ceiling or the clad wall.

To achieve this object, it is proposed according to the invention that the carrying device is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. In the first variant of this carrying device, it is sufficient if two holding elements are attached to two adjacent supports per plate. The support elements also holding this plate are only pluggably connected to the carrier and they do not require any special fastening elements such as screws, rivets and the like. Overall, the assembly effort is reduced to half even if one of them assumes that the known hooks only require a fastening hole and a fastening element. The simplification of the assembly naturally results in cost savings and a reduction in the assembly time due to the reduced assembly time.

The free groove edges can directly form attachments for the panels with their edges or surfaces facing the back of the panel. In the case of sensitive plates, it is useful if the plates keep a certain distance from the groove edges and the support is not completely rigid.

The "clear groove width" is measured in the case of wall cladding and thus in the case of vertical beams in the horizontal direction, namely parallel to the wall or plate plane. Accordingly, "the clear distance from the groove base to the longitudinal strips or the like." also in the horizontal direction, but measured perpendicular to the wall. The "total thickness" of the two fastening legs of a holding element and a support element directly assigned to it is measured in the direction of the clear distance, that is to say in the horizontal direction perpendicular to the wall plane. It is determined so that after fastening the holding element to the carrier, the fastening element of the support element directly associated with this holding element for the plate located above it can be easily pushed into the holding groove from above (without any play) (in the case of a wall covering).

From the above it has also become clear that one speaks of a "holding element located below" only in the case of wall cladding. For a ceiling cladding one could speak of "in front" and "behind". As in the known prior art, the retaining tabs of the two elements are of course assigned to the front of the panel, i.e. the visible panel side, i.e. the holding element and the support element encompass the upper and lower edge of the plate, so that a total of four holding tabs are visible with four elements.

The support elements and the holding elements engage with their fastening legs in the associated holding groove of their wearer. This means that both the support element and the holding element extend through the constriction between the two longitudinal strips to such an extent that their retaining tab is at a distance corresponding to or slightly greater than the thickness of the support from the support of the wearer. At least in the area of the two longitudinal strips, the holding element and the supporting element must be narrower in the horizontal direction and measured parallel to the plate plane than the fastening leg measured in the direction parallel to this.

For the bottom plate, a complete holding element is not required per se, rather an element can be used that is similar to a holding element, but has no holding tab. This is first on the assigned holding groove of his Carrier attached, in particular riveted. A support element is supported on this with an upward-pointing retaining tab. The bottom plate can then already be installed with two such support elements. Then you insert a holding element from above into each carrier, which includes the corresponding upper edge of this plate. After the two or all of the holding elements to be assigned to this plate are fastened to their associated support, a supporting element is placed on each holding element, and then the second plate can then be mounted, etc. Of course, all supports have been correctly aligned and fastened beforehand.

The second variant differs from the first one essentially in that the holding element is not firmly connected to the carrier, for example riveted, but is merely mounted thereon in a displaceable manner. In order to be able to transmit the forces from the wall or ceiling cladding to the beams and thus the wall or ceiling, a transmission element is used at each joint - horizontal joint for wall cladding - in the area of a pair of elements consisting of a support element and a holding element. This is firmly connected to the carrier. It forms a stop member and an element for power transmission for a support element. The holding element which is directly associated with the latter can also rest against it or be at a short distance corresponding to the usual play or thermal expansion. Forces arising from the holding element, for example due to suction, are immediate transferred to the carrier and forwarded by the latter directly or indirectly to the wall or ceiling. In contrast, the weight of the plate and possibly an additional force that occurs are transferred via the support element to the transmission element, which transmits it to the carrier. The attachment of the transmission element to the carrier is possible in the same way as that of the holding element on the carrier of the first variant. In this respect, there is no higher assembly effort. Furthermore, the support elements can be attached as easily as with the other variant. The latter also applies to the holding element and the transmission element. Compared to the first variant, an additional effort therefore only consists in the use of a further part and the attachment of three parts compared to two parts in the first embodiment. On the other hand, this nevertheless brings advantages overall, which lie, for example, in the fact that, in the second embodiment, wind suction forces can be dissipated directly onto the carrier by positive locking and thus an axial tensile force on the fastening element, in particular on the rivet, is eliminated. Furthermore, a particularly favorable transfer of the weight to the support element is possible if the same plate sizes and weights are used in both variants. Finally, the possibility of a technically flawless and particularly simple design of the profile joints should also be mentioned, which is particularly important if a plate extends beyond a joint of adjacent beams. Adjacent beams must not be directly connected to each other, rather a small longitudinal distance is required.

A further embodiment of the invention provides that, when the holding element is fastened to the carrier, the clear distance from the groove base to the longitudinal strips or the like. corresponds approximately to the total thickness of a fastening leg of a holding and a supporting element. After the fastening of the holding element on the carrier, there is still enough space in the groove that the fastening leg of the supporting element can be pushed in front of that of the holding element, in which case both fill the groove together. In the case of a wall cladding, the support element is pushed down until its fastening leg is supported on the support member of the holding element, which overlaps the upper edge of the plate. The inserted support element then engages under the lower edge of the next higher plate. "Clear groove width" is understood to mean the groove width measured parallel to the plate planes and perpendicular to the longitudinal axis of the beam.

A further development of the invention provides that the support member is formed by a middle piece of the essentially Z-shaped holding element. In this case, "Z-shaped" means that the holding element has two parallel legs which are connected via a leg which is in particular perpendicular thereto, one parallel leg forming the holding tab and the other parallel leg forming the fastening leg of the holding element. The middle connecting tab is the mentioned support member. Furthermore, it should be expressly noted at this point that, of course, also the lowest holding element, which is only used to support the supporting element located above it is needed, can be designed exactly like any holding element fastened above. The unnecessary retaining tab of the lowest retaining element is normally not disturbing from a technical point of view and is therefore without disadvantage.

A preferred embodiment of the invention is characterized in that the longitudinal strips at the same time form the systems for wall or ceiling cladding panels or are at least directly assigned to them. Accordingly, each holding groove has a Z-shaped cross section.

Another variant of the invention is characterized in that the fastening leg of the holding element has at least one fastening hole for a fastening element, in particular a rivet or the like. having. This fastening bore is preferably assigned to the longitudinal center plane of the holding element. It is assumed here that the holding element has a longitudinal plane of symmetry, and this preferably also applies to the support element. For the rest, a further embodiment of the invention provides that the support element has an essentially Z-shaped shape, that is to say also consists of two parallel legs and a connecting leg which is in particular perpendicular thereto.

A further development of the invention consists in the fact that the fastening leg of the support element extends in the longitudinal direction of the carrier and is open towards the bottom of the retaining groove Has groove in the area of the mounting hole of an associated holding element. This enables the support element to be lowered onto its holding element largely without play even when the fastening element for the holding element, for example a rivet head, protrudes against the wall cladding panel. This open groove can be provided in the form of a bead on the fastening leg of the support element, the bead having to be dimensioned such that it can protrude through the opposing longitudinal strips of the retaining groove, at least between these longitudinal strips.

A preferred variant of the invention is characterized by an at least partially strip-shaped pressing element, which is held in the retaining groove in a resilient manner and projects slightly beyond the outside. The wall cladding panel can therefore only rest on the pressure element but not on the system of the holding groove or its longitudinal strips. This pressing element can be a part whose length corresponds approximately to the plate height. Instead, several short pressing elements are also possible, with one and the same plate being assigned on both sides, for example two or three pressing elements arranged one above the other. However, an embodiment is preferred, which is characterized in that each pressing element extends approximately from a support element to the holding element assigned to the same plate. If the pressure element as well as the support element from top to bottom in the holding groove is inserted, a pressing element is mounted after each holding element and then the support element with the plate. It is more expedient, however, if the pressure elements are designed such that they can be sprinkled into the holding groove from the front, so to speak, perpendicular to the plane of the plate.

This is particularly possible if, according to another embodiment of the invention, the pressing element made of elastic plastic, rubber or the like. exists and has an approximately arc-shaped or tubular cross-section, the tubular cross-section being connected to a retaining strip.

As already indicated, each plate, in particular with its two vertical longitudinal regions, lies against a pressure element or a pressure element group. These press the plate against the holding tabs of their holding and supporting elements. In addition, a sufficiently large friction arises on the back of the plate in the area of each pressing element, so that lateral displacement of the plates can be reliably prevented, at least under normal stress. As a result, the plates can be held not only in the vertical, but also in the horizontal direction at the intended lateral distance. For the rest, a particular advantage of this carrying device can also be seen in the fact that, in the case of ceramic plates, for example, but also in the case of a whole series of other plates, one inevitably or even in a desired manner Column does not see the support device located behind. This means that the lateral plate edges project laterally in the horizontal direction over their holding groove or, in other words, that the gap between adjacent vertical edges is smaller, in particular is considerably smaller than the distance between adjacent holding grooves of one and the same carrier measured in the same direction.

A further variant of the invention is characterized in that the transmission element has a fastening leg which engages in a groove depression of the groove base of the holding groove which corresponds approximately to its thickness. This makes it possible to move the support element past it after mounting the transmission element or its attachment to the carrier, the mounting leg of which, in contrast to the first variant, fills the holding groove alone at this point. The assembly of the support element is complete when it has hit the support leg of the transmission element. The plate can then be placed on the support element or elements. The latter transfer the plate weight, as already explained, or the like via the support legs of the transmission element and its fastening rivets. on the carrier. As soon as the holding element is mounted on the carrier, this plate is held securely.

An advantageous development of the invention is characterized in that the height of the fastening leg of the support element and the holding element is approximately the clear width between the longitudinal strips corresponds to the holding grooves or may also be somewhat smaller. During assembly, the holding element as well as the support element is held in a position offset by 90 ° relative to its position of use, and after its fastening leg has passed through the space between the two longitudinal strips, it is rotated by 90 °, so that the lateral ends of each fastening leg each have one Reach behind the longitudinal bar. In order to be able to make this 90 ° rotation, it may be expedient to round off these free ends of the fastening leg accordingly.

As already explained, there is at least two pairs of elements, each consisting of a support element and a holding element, in a wall covering on each horizontal joint between two plates arranged one above the other, with a transmission element in particular also being used. Of course, at least two supporting elements are required at the lower edge of each lowermost plate, while only at least two holding elements are required at the upper edge of each uppermost plate. In the second embodiment of the invention, a transmission element can be dispensed with at the lower edge of the lowermost plates if instead, based on the first variant, each support element is directly connected to the carrier, for example riveted. It may be expedient if the design of such a support element deviates somewhat from that in the area of horizontal joints, if necessary. However, it is at the top of the top plate useful if you keep the use of a transmission element, although no further support element is supported on this. However, it can perform its function as a protection against displacement for the holding element overlapped above. It may be expedient if the fastening leg of these uppermost transmission elements is chosen to be shorter or possibly shortened. It is particularly advantageous if a corresponding predetermined breaking point is provided on the fastening leg so that it can be slightly shortened, in particular halved.

If the fastening leg of the support element expediently a receptacle, in particular a bead-like bulge, or the like for gripping over a rivet head. of the transmission element, this can make assembly by a 90 ° rotation impossible, as in the embodiment of the drawing. On the other hand, such a support element can be of particular importance in the area of a joint between two beams mounted one above the other because it can easily bridge this gap between the beams. Furthermore, such a support element can also be used successfully at the lower end of a wall covering or at the beginning end of a ceiling covering if it is to support the lower edge of the lowermost panel and extend downward beyond the lower end of the beam. In the latter application, it is very advantageous if there is a fastening hole on the fastening leg of this support element, the receptacle being located between the fastening hole and the support member of the support element, in particular extends to the latter. This favors use in the area of a beam joint or may make it possible in the first place.

A preferred embodiment of the transmission element is characterized in that it carries a support leg at both ends of its fastening leg, at least the support leg which engages between a holding element and an adjacent support element is angled again in opposite directions to form a spacer. This means that even with a relatively thin starting material, in particular sheet metal, a comparatively wide joint can be created between adjacent panels or one above the other with the aid of this transmission element. It is particularly advantageous if there is a spacer at both ends of the transmission element, that is to say each of the two support legs is angled again in opposite directions and the spacers are of different heights. This transmission element can be mounted, in particular riveted, in two positions offset by 180 ° and one can then use the spacers of different heights to optionally create a larger or smaller joint between adjacent or stacked plates. The aforementioned height of the transmission element is measured in the longitudinal direction of the carrier or in the direction of the joint width. The length of the support legs, measured transversely to the plane of the plate, is preferably of the same size, but can be different. The longer you choose the support leg, the wider the support element undermined and the cheaper this is for the burden of the latter. By using the transmission element, one obtains a shortened lever arm of the load application and thus a relief in the area of the corner at the transition from the fastening leg of the support element to its support member which engages under the lower plate edge.

Further refinements and associated advantages of these carrying devices result from the claims and the following description of two exemplary embodiments.

In the following, only a support device for a wall covering is explained in more detail, although the support device can of course also be used analogously for a ceiling covering.

In the embodiment of FIGS. 1 to 3, several beams 2 - in this embodiment indirectly - are fastened to the wall 1 to be covered, these beams all extending in the vertical direction and their lateral spacing - calculated from the center of the beam to the center of the beam - approximately the width of a wall cladding panel in the horizontal direction measured corresponds. As can be seen indirectly from FIG. 2, each wall cladding panel 3 is supported on its lower longitudinal edge by two support elements 5, each of which is assigned to one of the lower corner regions. The upper corner areas are accordingly assigned two holding elements 6, with all the supporting elements and holding elements of a left and also a right edge area of all the covering panels arranged one above the other being arranged along an imaginary vertical. As mentioned, the support elements 5 encompass the lower edge region of their cladding panel 3, while the holding elements 6 grip around and hold the upper edge region of the cladding panel 3. The weight of the plate is transferred from the support elements 5 to the carrier 2, specifically indirectly via the holding element 6 arranged under each support element, which is firmly connected to the carrier. For this purpose, a mounting hole 8 is attached to the upwardly projecting fastening leg 7 of the holding element 6. A fastening element, for example a rivet 11, is inserted through this and a hole located behind it on the strip 9 or 10 of the carrier 2. The exemplary embodiment is a so-called blind rivet which enables riveting from one side, namely from the front.

According to the present invention, each carrier has two holding grooves 12 and 13 which are arranged at a lateral distance and run in their longitudinal direction and are open towards the plate plane. Each serves to hold holding elements 6 and supporting elements 5, the exact number depending on the number of plates 3 arranged one above the other and assigned to each carrier. As can be seen particularly clearly from FIG. 3, the retaining grooves 12 and 13 are narrowed outward by longitudinal strips 15 and 16, which are arranged opposite one another and spaced from the groove base 14 (FIG. 1). In the embodiment, these longitudinal strips 15 and 16 are located at the free ends of the lateral U-legs 17 and 18, so that each holding groove 12 or 13 with its longitudinal strips 15 and 16 together has a C-shaped cross section. As can be seen from FIG. 1, however, this C-shaped cross section is only a left and a right partial area of the carrier 2, which is designed as an drawn aluminum profile, for example.

The clear width of each retaining groove 12 or 13, that is, the lateral distance between the two U-legs 17 and 18 corresponds approximately to the width of the fastening leg 7, the holding element 6 and the fastening leg 19 of the support element 5. In addition, the clear distance corresponds to the two longitudinal strips 15 and 16 taken from the bottom of the groove, ie the inner surface of the crosspiece 20, the total thickness of one fastening leg 7 and 19 of a holding element 6 and a supporting element 5. The Thickness of the fastening leg 19 of the support element 5 is denoted by 21 in FIG. 3. The thickness of the fastening leg 7 of the holding element 6 is measured in the same way. If both are the same thickness, fill in the retaining groove 12 or 13, measured half perpendicular to the plate plane.

The middle part of the cross-sectionally Z-shaped holding element 6 forms a support member 22. When the holding element 6 is fastened, in particular riveted to the crosspiece, and then a support element 5 is inserted into the relevant holding groove 12 or 13 in the direction of arrow 23 (FIG. 3) , this insertion movement ends when the lower end of the fastening leg 19 has hit the support member 22 of the holding element 6. For this reason, the weight applied to the center piece 24 of the support element or the corresponding proportion by weight is applied to the support member 22 via the fastening leg 19. From there, the load on the mounting leg 7 and the rivet 11 or the like. transferred to the carrier 2. The holding tab 25 of the holding element 6 or 26 of the support element 5 only serves to press the assigned cladding panel 3 against the carrier 2.

According to a particularly preferred embodiment of the invention, however, the plates 3 do not lie directly on the supports or the outer surfaces of the longitudinal strips 15 and 16, but rather on pressing elements 27. The central region thereof is above the outer surface of the support of the carrier or the longitudinal strips 15 and 16 in front. This is achieved in particular by means of an arcuate cross section of the pressing elements 27. They are preferably made of rubber or flexible plastic, so that sufficient friction is generated between the back surface of the plate and the pressing element 27. The latter thus ensure the position of each plate seen in the horizontal direction, so that the lateral plate distance 28 (Fig. 2) is maintained at the usual loads. The vertical plate spacing 29 is determined by the height of the fastening leg 19 of the support element 5 measured in the vertical direction.

A bead-like groove 30 is attached to the fastening leg 19 of the support element 5. It also enables the support element 5 to be pushed in in the direction of the arrow 23 when a rivet head protrudes beyond the surface of the fastening leg 7 pointing towards the plate 3. Measured in the horizontal direction, the outer width of the groove 30 is less than the clear width between the two longitudinal strips 15 and 16.

As already explained, each carrier 2 has an essentially U-shaped cross section, the retaining grooves 12 and 13 being attached to the free U-legs, in particular being integrally formed. Two inwardly facing strips 31 and 32 create a channel 33 for inserting a tubular connecting piece 34. It is held in a suitable manner, for example by friction, and in the exemplary embodiment of FIG. 2 projects upwards, so that a further carrier 2 can be plugged onto the projecting end, which extends the carrier shown upwards. Otherwise, the two U-legs 35 and 36 merge directly into the inner leg of each retaining groove 12 or 13.

In the exemplary embodiment, each carrier 2 is fastened to the wall 1 with at least two holders 37 arranged one above the other, preferably U-shaped in cross section. For example, such a holder 37 is assigned to each upper and lower carrier end. In the case of longer supports, at least one additional holder can be provided between the upper and lower holders. The clear width of the two legs 38 and 39 of each holder 37 is dimensioned so that the U-cross section of the carrier 2 can be inserted exactly fitting. Each holder 37 is fastened, for example, with the aid of two screws 40 which are screwed into dowels 41. The usual spacer rings are also provided.

At the free U-leg edges 42 and 43 you can create the backs of the cross-sectionally C-shaped holding grooves 12 and 13. In the area of each free leg end of the holder 37 there are elongated holes 44 and bores 45. Self-tapping screws 46 are rotated through these, for example, in order to thereby establish the connection with the carrier 2. If you use the holes 45 or at least part of it, there is a rigid connection with the holder 37 and thus also the wall 1. If instead the screws are passed through the elongated holes, then there is a vertical displacement movement of the carrier in the holder 37 within the dimensions of the or Elongated holes possible. In this way, a carrier can be attached to the wall 1 with a fixed and at least one displaceable bearing. It is also possible to fasten two mutually extending supports 2 in the area of a holder 37.

The two holding grooves 12, 13 can also be manufactured separately and connected in a suitable manner to the holder 37 or the wall 1.

Also in the second embodiment according to FIGS. 4 to 9 is a wall covering. On the wall, not shown, several carriers 2 are mounted one above the other. In this exemplary embodiment, there are two beams one above the other in order to be able to demonstrate the upper end of the covering, a joint between adjacent beams and the lower end of the covering. However, it can easily be a plurality of carriers extending from one another. In addition, each wall cladding panel 3 is supported on at least two such beams or pairs of beams mounted at a lateral distance. For example, in FIG. 4 the upper plate protruding to the right extends beyond the gap 47 between successive supports 2. Such gaps are necessary according to the usual assembly instructions. They require special training and assembly of the support element in this area.

If one looks at the left half of FIG. 4 with the wall cladding panel 3 projecting to the left, it can be seen that its upper edge area is overlapped by a holding element 48 and thereby held. 5, this holding element is shown in perspective and somewhat enlarged. The transmission element 49 shown in detail and also enlarged in FIG. 6 is fastened, in particular riveted, to the groove base 14 of the holding groove 12 or 13. For this purpose, it has at least one fastening hole 50 and 51 in the exemplary embodiment for the reasons mentioned below. The fastening is carried out with the aid of a rivet, in particular a blind rivet 52 (FIG. 4). The width 53 of the transmission element 49 is selected so that it can be pushed between the longitudinal strips 15 and 16 and then riveted to the groove base. The transmission element is made of a thin sheet of metal. The material thickness and thus the thickness of its mounting leg 54 is selected so that it can be accommodated completely in a groove 74. Its outward-facing surface then runs approximately flush with the groove base 14. A support leg 55 or 56 connects to the upper and lower end of the fastening leg 54. The free end of each support leg is angled in opposite directions, so that spacers 57 and 58 are formed. Measured in the longitudinal direction of the carrier 2 or the fastening leg 54, the Height of the spacers 57, 58 different. In the exemplary embodiment, the height of the spacer 57 is approximately twice that of the spacer 58. The latter is 4 mm, for example. This makes it possible to mount the spacer optionally in one of two positions offset by 180 ° and thereby achieve different joint widths 59.

The distance between the two support legs 55 and 56 of the transmission element 49 is selected so that between them there is space for the mounting leg 60 of a support element 61 rotated by 90 ° relative to its position of use. In this position of the support element (61 a) shown in FIG. 4, the latter can be pushed through the gap between the two longitudinal strips 15 and 16. After a 90 ° rotation in the direction of arrow 62 (FIG. 4), the lateral, preferably rounded ends of the fastening leg 60 of the support element 61 engage in the associated holding groove 12 or 13, that is to say they engage behind the outer longitudinal strips 15 and 16. In the embodiment of Fig. 6, the mounting holes 50 and 51 are also mounted so that the support member 61 can be mounted in the manner described without hindrance by the above fastening rivet or rivet head. This means that the width 63 of the mounting leg 60 of the support element 61 is less than the distance of the mounting hole 50 from the support leg 55. The same applies to the mounting hole 51 and the support leg 56.

After the support element 61 has been inserted and rotated, its outwardly projecting horizontal leg or the support member 64 rests on the associated support leg 55 or 56 of the transmission element 49. A wall cladding panel 3 can now be inserted in at least two support elements 61 which are laterally spaced apart. Their weight is transferred from the support member 64 to the support leg 55 and from there via the rivet 52 to the carrier 2. From the latter, the weight load is passed on to the wall to which it is attached. The same applies analogously to the other forces occurring, for example wind pressure, suction, etc. The upwardly projecting free leg 65 of the support element 61 secures the plate against lifting off from the carrier 2. After the plate 3 has been supported in this way, it is pushed above its upper edge a holding element 48 into the groove 12 or 13. In the exemplary embodiment, this is shaped and dimensioned the same as the support element 61. It is mounted according to FIG. 4 in a corresponding manner, namely inserted in a position offset by 90 ° relative to the position of use and then rotated in the direction of arrow 66. In this case, the rotation takes place clockwise, while the support element 61 is rotated counterclockwise according to FIG. 4. As a result, the free leg 65 of the holding element 48 then projects downward. 4, it overlaps the upper edge of the plate 3.

The next transmission element 49 is then attached or riveted. This can be downward-pointing Spacer 57 abut the leg or support member 64 of the holding element 48 located thereunder or have a small distance therefrom. However, this must be so large that rotation of the assembled holding element 48 into its disassembled position is prevented. Only a small game is planned there.

To hold the upper plate edge of the uppermost plate, the lower fastening hole 51 of the transmission element 49 can be used in the position of use. Here, a short, in particular half, transmission element 49 is sufficient, as the upper end of FIG. 4 shows. In order to be able to halve the transmission element 49, in the exemplary embodiment it is equipped with a predetermined breaking point 66.

Half a transmission element 49 is also sufficient in the region of a joint or a gap 47 between supports 2 arranged one above the other. However, because the head of the fastening member 66 protrudes into the holding groove 12 or 13 and it can hinder the lowering of the support element 61 located above it, a modified support element 67 is used in the area of such a joint. The height of its fastening leg 68 is preferably greater than that of the fastening leg 60 of the support element 61. As a result, it cannot be installed by an insertion and subsequent rotary movement, but only by a sliding movement in the direction of arrow 69. In order to be able to be pushed past the rivet head mentioned , is also a receptacle on the mounting leg 69 of this modified support member 67 70, in particular a bead-like bulge, is provided. As a result, this support element can also be lowered until it rests on the associated support leg of the transmission element 49. It remains to be added that the height 71 of the fastening leg 60 of the support element 61 or of the holding element 48 is somewhat less than the clear width between the longitudinal strips 15 and 16.

The lower end of a cladding panel 3 can also be supported at the lower end of each support 2 with the aid of a modified support element 67. No transmission element 49 is then required at this point. For this purpose, however, the support element 67 must be connected directly to the carrier, i.e. riveted to these. This is done with the aid of a rivet, in particular a blind rivet 72, which penetrates a corresponding fastening hole 73 of the support element 67 and a correspondingly drilled hole on the groove base 14 or the groove recess 74.

FIG. 8 shows another embodiment of the pressing element 27. It differs from that of FIG. 2 by a changed cross-sectional shape, but it is held in the same way in the holding groove 12 or 13 of the carrier 2, in particular pushed in. It is located between a holding element and a supporting element supporting the same plate. As a result, its length is somewhat less than that of a panel 3. It also creates a flat visible surface of the facade panels by compensating for panel thickness tolerances and the panels in each case presses away from the wall against the free legs 65. At the same time, a lateral displacement of the panels is prevented, so that the lateral joint spacing or panel spacing 28 is also reliably maintained. This also eliminates rattling noises. The longitudinal edges of its retaining strip 57 engage in the grooves 12 and 13, that is, they engage behind the longitudinal strips 15 and 16 of each retaining groove, while the part 76 of tubular cross section passes between the longitudinal strips 15 and 16 to the outside and directly or, as in the exemplary embodiment 8, with externally attached support strips 77, 78 abuts the back of the plate.

Regarding the second variant, it should also be noted that wind suction forces do not produce any axial tensile force on the rivets. By supporting the support element on the support leg of the transmission element, there is a shortened lever arm of the load application, which has a positive effect on the load and thus also the stability of the support element. For the rest, a plastic coating, in particular powder coating, reduces or eliminates stress corrosion at the bending edges. By simply screwing in the holding elements, the facade panel used is immediately held without the need for simultaneous riveting or the like. The overlapping of a gap or a gap between successive beams 2 without a connection of forces from profile to profile is also to be emphasized positively.
