Description

The invention relates to a facade or roof cladding with cladding elements that are fixed with fastening elements to a substructure with slats running along a row of cladding elements.

It has long been known that a facade or a roof of a building can be covered with many cladding elements arranged next to one another, with the individual cladding elements being fixed to a substructure. The substructure usually has a number of slats running parallel to one another, with the individual cladding elements each being fastened to at least one of these slats. In order to be able to completely cover a facade or a roof with the cladding elements, a row of cladding elements is usually arranged and fixed along each slat. The spacing of the slats is expediently specified in relation to the dimensions of the cladding elements such that a lower edge of the cladding elements of a row of cladding elements arranged higher overlaps an upper edge of a row of cladding elements which are fixed to a slat arranged below. In this way, for example, rear-ventilated facades or roof coverings can be produced.

The cladding elements may be planar slabs of natural material such as slate. Facade elements or roofing tiles are also known from practice which have a complex shape and thereby facilitate attachment of the individual cladding elements to the substructure or enable positive engagement with cladding elements arranged adjacent to one another.

In order to be able to fix the individual cladding elements to the slats of the substructure, various fastening systems are known. For example, in DE 196 17 269 C2 or in AT 001 970 U1 Fastening brackets are shown and described, which can be fixed to the substructure and engage around an edge region of a cladding element with clamp-like projections in order to be able to fix the cladding element to the substructure. In the case of such fastening clamps, it can be regarded as a disadvantage that the individual clamp sections, which grip the cladding elements, remain visible when the facade or roof cladding is finished and impair the overall visual impression of the facade or roof cladding.

For example in DE 20 2011 101 655 U1 or in DE 202 14 938 U1 Fastening systems are described in which horizontal support profiles are attached to the substructure and the individual cladding elements have shapes adapted to these support profiles on their rear side facing the substructure so that they can be inserted either horizontally or vertically into the support profiles and fixed to them. With such Fastening systems, it is felt to be disadvantageous that the dimensions of the support profiles and the shapes adapted to them in the cladding elements must be specified with great precision and adapted to one another and, in addition, the individual support profiles must be attached to the substructure as precisely as possible at a predetermined distance and parallel to one another, to enable the individual cladding elements to be fastened to the substructure without any gaps. The manufacturing and assembly costs required for this are considerable.

In DE 203 17 588 U1 describes a facade or roof covering with rectangular panels that are attached to a substructure by means of clamping hooks. The individual clamping hooks can be hung on the slats running along a row of cladding elements and each encompass a head region of a lower cladding element projecting from below onto the slat and a foot region of an upper cladding element extending upwards. A disadvantage of this fastening system is the minimum distance, which is predetermined by the width of the clamping elements, between two cladding elements which are arranged next to one another along a row of cladding elements and are separated from one another by the clamping hook fixed between them on the slat. In addition, an end section of the clamping hook gripping the foot area of a cladding element is visible and impairs the overall aesthetic impression of such a facade or roof cladding.

It is therefore considered an object of the present invention to design a facade or roof cladding with cladding elements in such a way that the individual cladding elements can be fixed to the substructure with fastening elements, the fastening elements should be able to be produced inexpensively and the individual cladding elements should be mounted on the substructure should be able to be carried out quickly and easily on site.

This object is achieved according to the invention in that each cladding element has a head region along an upper edge running along the row of cladding elements with a slat support leg extending from an outside of the facade or roof cladding in the direction of the substructure for supporting the head region on an upper side of the slat and along a along the lower edge running along the row of cladding elements has a foot region with an engagement recess, and that the fastening element has a slat engagement section at a first end, which extends along a rear side of the slat opposite the outside of the facade or roof cladding from an upper slat edge to a lower slat edge and on one of the top opposite underside of the slat abuts that the fastener has a head holding portion with which the slat support leg of a first covering ngselements is held on top of the slat, and that the fastener at an opposite end of the slat rear engagement portion has a foot engagement portion in a Engagement recess engages in the foot portion of a second trim element and presses the foot portion of the second trim element against the head portion of the first trim element and both together towards the slat. The shape of the head area of the cladding element with the batten support leg extending in the direction of the substructure makes it possible in a simple manner for the head area of the cladding element to rest and be supported on the upper side of the associated slat. The only thing that needs to be achieved with the fastening element is that the head region of the cladding element can no longer unintentionally become detached from the upper side of the slat. The weight of the trim member is transferred to the batten via the batten support leg of the trim member, and the trim member is supported and carried directly by the batten. Consequently, the fastening element does not have to be able to absorb and dissipate any significant weight of the cladding element fixed to the slat with the fastening element.

By designing the cladding element in the foot area with an engagement recess and a foot engagement section of the fastening element adapted thereto, which can engage in the engagement recess in the foot area of the cladding element and thereby press the foot area of the cladding element in the direction of the substructure and in this way fix it to the substructure , In a simple manner, a form-fitting determination of the cladding elements in the respective head area on a first upper slat and in the respective foot area on a second slat running underneath.

It is considered particularly advantageous here that each cladding element is fixed in a form-fitting manner to a slat of the substructure both with its head area and with its foot area. The risk of undesired detachment of individual cladding elements from the composite of the facade or roof cladding is thus reduced to the greatest extent possible, as is the risk of undesired loosening of individual cladding elements, which could then move and rattle, for example, when the wind blows against the facade or roof cladding.

The fastening element is designed in such a way that the fastening element with the slat gripping section can be reliably fixed to a slat and thereby positively engage behind a rear side of the slat. In the installed position, the fastening element fixes a head region of a first cladding element to the slat and also grips a foot region of a second cladding element in a form-fitting manner, which is arranged in a cladding element row arranged above it. With the fastening element, the foot area of the second cladding element is pressed against the head area of the first cladding element and both together in the direction of the slat. Due to the overlapping arrangement of the rows of cladding elements arranged one above the other, the foot region of the second cladding element, which is arranged above the first cladding element, overlaps the head region of the first cladding element and thereby also covers the fastening element, which is arranged in the head region of the first covering element. Since this fastening element engages in the foot area of the second cladding element arranged above it from a rear side facing the substructure, the fastening element is not visible from an outside of the facade or roof cladding.

The substructure of the facade or roof cladding can be made of wood or metal, for example. It is also possible that the substructure is made of different materials. The slats can also be made of either wood or metal. A metallic slat can be, for example, a hollow profile or a solid profile made of aluminum or another suitable metal.

In order to erect the facade or roof cladding according to the invention on site, it is expedient to start with a bottom row of cladding elements and place a row of cladding elements with their respective head area on a bottom batten. Each cladding element is then expediently fixed to the bottom batten with at least one fastening element, with the fastening element being fixed from a rear side of the bottom slat to its underside and the head holding section of the fastening element encompassing the head region of the cladding element, so that the head region of the cladding element is fixed to the bottom batten is. A row of cladding elements arranged above this can then be arranged and fixed to a slat running above it. This is what each Covering element in the row arranged above it is inserted with its engagement recess arranged in the foot area into the foot engagement section of the associated fastening element on the bottom slat and then brought up with its head area to the slat arranged above and supported with the slat support leg on the slat arranged above it. The row of cladding elements arranged above it can then be fixed again with fastening elements on the slat assigned to this row. Following this, a further row of cladding elements arranged again above it can be fixed to a further slat arranged above it until the complete facade or roof cladding is completed.

In the case of the facade or roof cladding according to the invention, it is also possible for a single, for example defective, cladding element to be detached from the assembly at any position within the facade or roof cladding and replaced by a newly inserted cladding element. For this purpose, after the defective cladding element has been detached, the upper cladding element arranged above the relevant cladding element must be grasped in its foot region and pivoted slightly away from the substructure against the retaining effect of the fastening element. The head area of the upper paneling element, the foot area of which is gripped and pivoted, remains connected to the slat arranged above it with the fastening element arranged there. As soon as the foot area of the upper trim element extends sufficiently outwards has been pivoted, the slat assigned to this foot area is accessible for the paneling element to be newly inserted. The head area of the cladding element to be newly inserted can then be inserted between the slightly outwardly pivoted foot area of the upper cladding element and the slat, coming from below. The head area of the lining element to be newly inserted and in particular the slat support leg protruding in the direction of the slat is guided along the front side of the slat until the slat support leg grips the top of the slat and the head area of the newly inserted lining element is in the intended end position with the slat support leg on the top supporting the bar. The slightly outwardly pivoted foot area of the upper cladding element can then be released again and the upper cladding element pivoted back into its original position.

In order to enable such a replacement of an individual cladding element in a combination of cladding elements of a facade or roof cladding, the fastening element in the area of the foot-engaging section and optionally also in the area of the head-retaining section only has to be sufficiently elastic or deformable to allow the pivoting of a to allow the panel member in engagement with the fastener in question away from the substructure. The required elasticity or deformability can be made possible by a suitable choice of material or by suitable shaping of the fastening element. If the individual cladding elements in consecutive rows of cladding elements are offset relative to one another, it may be necessary to remove a single cladding element by bending open the two cladding elements located in the row of cladding elements arranged above and overlapping the cladding element to be detached in order to make the head area of the cladding element to be detached accessible from the outside.

A configuration of the head area that is advantageous for the manufacture and assembly of a cladding element provides that the slat support leg has a straight course up to an end area of the slat support leg that faces the slat. The slat support limb then rests on the upper side of the slat with an end edge of the slat support limb facing the slat.

According to a further embodiment of the idea of the invention, it is provided that the slat support leg of the cladding element has, at an end region facing the slat, an angled support end section directed in the direction of the top side of the slat, with an end face facing the top side of the slat, which is adapted in this way to an inclination of the cladding element relative to a cladding level is adapted so that the supporting end section rests flat on the upper side of the slat. Since the foot area of a cladding element rests from the outside on the head area of a cladding element arranged underneath, the foot area of the cladding element is at a greater distance from the substructure than the head area of the relevant one cladding element. The cladding element is therefore arranged at an angle relative to the cladding plane, which is defined by the substructure or by the outwardly directed outer sides of the slats arranged at a distance from one another. In order to enable a large contact surface for the slat support leg on the upper side of the slats, the end face of the bearing end section of the slat section leg resting on the upper side of the slat is designed with a corresponding inclination, so that the end face rests over the entire surface on the upper side of the slat and the weight of the covering element lying on it the entire face is removed onto the batten. The angled support end section, which is directed towards the top of the slat from above, can also make it more difficult for the slat support leg to move laterally on the surface of the slat, thereby supporting the arrangement and fixing of the head region of the covering element on the associated slat.

In order to enable the foot engagement section of a fastening element to engage in a form-fitting manner in the foot area of an associated cladding element, one embodiment of the concept of the invention provides for the engagement recess in the foot area to be formed by an engagement pocket, which is formed between an outer surface of the cladding element and an engagement leg which parallel to the outer surface in the direction of the substructure, spaced therefrom and aligned in the direction of the head section. This engagement leg is along a lower edge of the Trim element connected to the outer surface of the trim element and extends towards the head area. In this way, a pocket-shaped recess, or the insertion pocket, is formed in the foot area between the outer surface of the lining element and the engagement leg formed at a distance therefrom. The access pocket is freely accessible from the head area of the covering element. In order to be able to mount the cladding element for the façade or roof cladding, the cladding element only has to be brought up to a head section of a cladding element already fixed to the substructure from below and brought up to the foot engagement section of the fastening element encompassing the head region of the already assembled cladding element such that the foot engagement section of the Fastener is pushed into the pocket. The dimensions of the foot engagement section of the fastening element already fixed to the substructure are expediently specified in such a way that the cladding element to be newly fastened can be pushed with its slat support leg in the head area over a slat assigned to this head area when the foot engagement section of the fastening element in the foot area of the cladding element is completely in the hand pocket is pushed in.

The lower edge of the cladding element can, for example, be V-shaped or arc-shaped in order to transition from the outer surface of the cladding element into the engagement leg, which is again directed in the direction of the head section. It is optionally possible that the header area of the cladding element and/or the foot region of the cladding element are U-shaped in cross section. The bearing end section angled from the slat support leg in the head area and the engaging leg of the lining element arranged in the foot area can each be aligned parallel to an outer surface of the lining element. The configuration of the head area and/or the foot area, which is U-shaped in cross section, can be designed either with rounded edges or with comparatively angular edge areas, depending on the desired appearance of the facade or roof cladding.

With regard to an aesthetically pleasing configuration of the facade or roof cladding, it is expedient, regardless of the respective shape of the head region and the foot region of a cladding element, for the outer side of the cladding element to be flat. The individual cladding elements can have a rectangular basic shape and outer surface. The cladding elements can be made of a natural material such as clay or wood. The cladding elements can also be made of a material such as stoneware or ceramic or concrete. It is also conceivable that the cladding elements are made of plastic or of a composite material made up of different components.

In order to be able to fix the head area of a cladding element as reliably as possible to the associated slat of the substructure, it is optionally considered advantageous that the head holding section has a Top of the slat support leg of the first cladding element abutting slat support leg section and an angled and in the head region of the first cladding element on the outside abutting head clamping section, with which the head region of the first cladding element is pressed against the slat. The slat support limb section of the fastening element prevents the head region of the cladding element resting on the slat from being displaced upwards, or the slat support limb from being able to be spaced apart from the upper side of the slat. The head clamping section, which bears against the outside of the head area, prevents the head area of the covering element from being pulled outwards from the slat and thereby being able to be removed from the outside of the slat. In principle, it is possible for the fastening element not to have a head clamping section and for the head region of the first cladding element to be pressed onto the slat solely by pressing the overlapping foot region of a second cladding element, with the second cladding element being arranged above the first cladding element and the fastening element being in the Foot area of the second paneling element arranged above engages and presses this foot area against the head area of the first paneling element and both paneling elements together against the slat. However, in addition to a separate fixation of the head area of the lining element in question, the head clamping section can support and facilitate the arrangement and fixing of the fastening element, which is thereby attached to the head area of the Covering element and is fixed to the underside of the associated slat in the intended mounting position. The fastening element can be fixed in this position during assembly without the need for the foot engagement section of the fastening element to subsequently engage in the engagement recess of a further connecting element which is fixed in a row of connecting elements arranged above it.

According to one embodiment of the inventive idea, it is provided that the foot engagement section runs at a distance from the outer surface of the first cladding element in its head area, directed from the top of the slat to its underside and engages in a form-fitting manner in the engagement recess in the foot area of the second cladding element, so that the foot area of the second Covering element can be inserted from the underside of the slat upwards with the engagement recess in the foot engaging portion of the fastening element until the head region of the second covering element can be supported on an upper side of a slat arranged above it. With such a configuration of the foot area of the cladding element and in particular the engagement recess in the foot area of the cladding element which is open towards the head area, a particularly simple and reliable assembly of the cladding element is facilitated. Before a second cladding element can be arranged and fastened on an upper slat, a first cladding element must first be fixed to a slat arranged underneath. The header of the first Trim panel is secured to the bottom batten with a single fastener or multiple fasteners where appropriate. The foot engaging portions of the fasteners secured to the bottom slat protrude slightly from the respective outer surface of the first trim member secured thereto and are oriented from the top of the bottom slat to the bottom thereof. The second cladding element to be fastened is placed with its foot area against the head area of the first and already fastened cladding element and pushed from below with the engagement recess open at the top into the protruding foot engagement section of the fastening element until the foot engagement section is completely inserted into the engagement recess and the head area of the second cladding element can be pushed over the top slat and fixed with the slat support leg on top of the top slat.

The foot engagement section of the fastening element can have a curved course and an engagement end directed to the outside or away from the substructure. In this way, the insertion of the engagement leg in the foot area of the cladding element into the foot engagement section can be facilitated. At the same time, a spring effect or a spring force acting in the direction of the substructure can be generated by the curved shape of the foot engagement section and exerted on the engagement leg or on the foot region of the cladding element.

It is optionally provided that the section that engages behind the slat has a U-shaped end section, so that an end face of an end leg of the fastening element that faces the slat rests on the underside of the slat. A spring effect can be generated by the U-shaped end section, and the section that engages behind the slat can be reliably fixed to the rear side and the underside of the slat. The end face of the end leg can be sharp-edged along a peripheral edge, so that the end leg resting with the end face on the underside of the slat can cant and claw on the underside of the slat. It is also conceivable that the end face of the end leg has one or more conically tapering points in order to promote a stronger clawing effect of the end leg on the underside of the slat.

It is preferably provided that the fastening element can be produced in one piece by folding from a planar sheet metal blank. In this way, the fastening element can be manufactured particularly inexpensively.

According to a particularly advantageous embodiment of the idea of the invention, it is alternatively provided that the fastening element is produced in one piece by folding from a piece of wire. Such a fastening element can be produced very cost-effectively with little material expenditure. The space required for transporting or storing such fasteners is extremely small.

A fastening element produced in one piece either from a planar sheet metal blank or from a piece of wire can be easily handled during assembly and reliably fixed around the head region of a cladding element on the associated slat. The protruding foot engagement section of the fastening element can be designed in a simple manner in such a way that the insertion of a foot region of a further covering element is possible in a particularly simple manner.

Optionally, it can be provided that the cladding element has at least one hole in its head area for a separate fixing of the head area with a screw or with a nail on a slat. In many cases it is expedient that a lowermost row of cladding elements is fixed only to a slat that is arranged and runs in the head area of this row of cladding elements. The foot area of the cladding elements fixed to this bottom slat cannot then be fixed and fixed in the usual way with further fastening elements. Such a bottom row of cladding elements can instead be additionally secured and fixed by a screw or a nail on the batten in question. It is also conceivable that, if necessary, further cladding elements that are fixed to slats arranged further up are also fixed and secured to the associated slat with a suitable fixing element through the bore.

An exemplary embodiment of the concept of the invention is explained in more detail below with the aid of schematic illustrations. It shows:

• figure 1 a sectional view of a slat of a substructure with a head area of a first cladding element attached thereto and a foot area of a second cladding element attached to this slat with a fastening element,
• figure 2 a sectional view of a cladding element designed according to the invention,
• figure 3 a side view of a fastener, wherein the fastener in figure 3 for the sake of clarity, not to scale in relation to the covering element in figure 2 , but is shown larger,
• figure 4 a perspective view of a facade cladding with several cladding elements that are fixed to a substructure,
• figure 5 a sectional view according to FIG figure 1 with paneling elements that have a differently designed head area, and
• figure 6 a sectional view of a facade cladding with several cladding elements, the head area of which is similar to that in figure 5 cladding elements shown is designed, wherein a second cladding element is pulled away with its foot area something from the substructure to a head portion of a first arranged underneath Being able to subsequently insert the cladding element accessible between the foot area of the second cladding element and the slat assigned to the head area.

In the figure 1 The sectional view shown shows a section of a facade or roof covering 1 according to the invention in the area of a horizontally running slat 2, which is part of an in figure 1 not shown substructure of the facade cladding 1 is. A first cladding element 4 and a second cladding element 5 are fixed to this slat 2 with a fastening element 3 . In figure 2 a sectional view through the structurally identical first and second cladding elements 4, 5 is shown. The facade or roof cladding 1 can consist of a number of structurally identical cladding elements 4.5, as shown in figure 2 are shown as examples, are constructed and manufactured. In figure 3 is the fastener 3 in front of its in figure 1 assembly shown on the batten 2 shown.

The cladding element 4, 5 has a planar outer side 6 and a figure 2 The sectional view shown has an approximately U-shaped head area 7 and a likewise approximately U-shaped foot area 8 . The head area 7 has a slat support leg 9 extending from the outside 6 in the opposite direction with an end area 10 facing the slat 2 in the assembled state, with a slat support leg 9 angled in this end area 10 and directed towards an upper side 11 of the slat Support end portion 12 has. An end face 13 of the support end section 12 facing the slat 2 runs obliquely or is designed with an inclination which is adapted to an inclination of the first covering element 4 fastened to the slat 2 in such a way that the end face 13 of the support end section 12 rests flat on the upper side 11 of the slat 2 . In figure 1 the head region 7 of the first cladding element 4 is shown as an example, which is supported on the upper side 11 of the slat 2 via the slat support leg 9 and the angled support end section 12 formed thereon. The outer side 6 of the first cladding element 4 fixed to the batten 2 as intended in the facade or roof cladding 1 has an inclination relative to a cladding plane, which in figure 1 corresponds to a front side 14 facing the outside 6 of the first cladding element 4 or to a rear side 15 facing the building (not shown) and opposite the front side 14 of the slat 2 with a rectangular cross section.

The head area 7 of the first cladding element 4 is connected to the in figure 3 Fastening element 3 shown on its own and in a relaxed state is fixed to the slat 2. For this purpose, the fastening element 3 has a slat engagement section 16 at a first end, which is located in the figure 1 shown assembled state along the back 15 of the slat 2 from an upper slat edge 17 to a lower slat edge 18 and the lower slat edge 18 surrounds. Here, the slat rear engagement portion 16 of the fastener 3 has a U-shaped end portion 19, so that an end face 20 of an underside 21 of the slat 2 facing end leg 22 of the end portion 19 at the Underside 21 of the slat 2 is present. The end face 20 of the end leg 22 can be sharp-edged along its peripheral edge or provided with a conically tapering tip or a profiled surface in order to support the end leg 22 clawing on the underside 21 of the slat 2 . Due to the U-shaped design of the end section 19, a spring effect can be generated which supports and improves a reliable and permanent fixing of the fastening element 3 to the slat 2.

In a central region of the fastening element 3, the slat gripping section 16 merges into a head holding section 23, which is located in the figure 1 shown mounted state, the head region 7 of the first cladding element 4 with the slat support leg 9 and the angled support end section 12 surrounds it. The head region 7 of the first paneling element 4 is pressed onto the top side 11 of the slat 2 with a slat support limb section 24 resting on an upper side of the slat support limb 9 . After the slat support leg section 24, the fastening element transitions into a head clamping section 25 which is angled therefrom and rests in the head region 7 of the first lining element 4 on its outside 6. The head region 7 of the first cladding element 4 is pressed in the direction of the rear side 15 of the slat 2 with the head clamping section 25 of the fastening element 3 . In this way, the first cladding element 4 resting on the slat 2 is fixed with the fastening element 3 . There is the first cladding element 4 with its own weight over the slat support leg 9 and the support end section 12 on the upper side 11 of the slat 2 is supported and the weight is carried away via it, the dead weight of the first cladding element 4 no longer has to be absorbed by the fastening element 3 and transferred to the substructure or to the slat 2 . The fastening element 3 can consequently be produced in a material-saving and cost-effective manner.

The fastening element 3 merges into a foot engagement section 26 at an end opposite the slat engagement section 16 . The foot engagement section is spaced apart from the outside 6 of the first cladding element 4 in its head area 7 offset parallel to the head holding section 23 and aligned from the top 11 of the slat 2 to the bottom 21 of the slat 2 . The foot engagement section 26 has a slightly curved course with an engagement end 27 directed away from the slat 2 .

In order to produce a facade or roof cladding 1 with the cladding elements 4, 5 designed according to the invention and the fastening elements 3, a first cladding element 4 must first be arranged with its head area 7 on the batten 2 in a lower row of cladding elements and with the fastening element 3 gripped around it and on the slat 2 be determined. The foot engagement section 26 of the fastening element 3 then protrudes slightly from the outside 6 in the head region 7 of the first cladding element 4 . A second lining element 5 to be arranged in a row of lining elements running above it can then be introduced with its foot region 8 into the foot engagement section 26 . For this purpose, the foot area 8 of the second paneling element 5 has an access pocket 28 that is open and accessible from above or from the head area 7 of the second paneling element 5, which is located between the outside 6 of the second paneling element 5 and an engaging leg 29 that is directed parallel to the outside 6 in the direction of the head area 7 of the second paneling element 5 is trained. The foot region 8 of the second covering element 5 lying on the outside 6 of the first covering element 4 can be introduced from below with the insertion pocket 28 into the foot engaging section 26 of the fastening element 3 until the foot engaging section 26 has been completely inserted into the insertion pocket 28 . In this position the in figure 1 No longer shown head region 7 of the second cladding element 5 over the top of a likewise not shown and above the figure 1 shown slat 2 pushed arranged further slat and fixed and supported on this further slat. In the fully assembled state, the foot engagement section 26, which is curved and thus designed with a spring effect, presses the engagement leg 29 lying against it and thus the foot area 8 of the second lining element 5 on the outside 6 of the head area 7 of the first lining element 4 and consequently the foot area 8 of the second lining element 5 together with the head area 7 of the first cladding element 4 to the slat 2. Due to the form-fitting engagement of the foot engagement section 26 of the fastening element 3 in the engagement pocket 28 formed in the foot area 8 of the second cladding element 5, the second cladding element 5 is attached both to the in figure 1 illustrated footer 8 as well as with the in figure 1 no longer Head area 7 shown positively and reliably fixed to the substructure formed by several slats 2.

In this way, an in figure 4 Façade or roof cladding 1 shown in more detail in a perspective view can be erected. where is in figure 4 a facade cladding 1 of an outer wall 30 of a building is shown as an example. A plurality of horizontally running slats 2 are also fixed to a plurality of vertically aligned fastening slats 31 which are arranged at a distance from one another. In the figure 4 Façade cladding 1 shown is erected starting with a bottom row 32 of cladding elements. For this purpose, the cladding elements with the head area 7 are arranged on the bottom slat 2 on the bottom slat 2 . In the bottom row of cladding elements 32 , the cladding elements 4 arranged on the lowest slat 2 are fixed to the lowest slat 2 with additional fastening screws 33 . The fastening screws 33 are passed through bores 34 or recesses arranged in the head region 7 of the cladding elements 4 of the lowermost cladding row 32 and are screwed into the lowermost slat 2 coming from the outside. The head area 7 of the cladding elements 4 of the bottom row of cladding elements 32 is additionally fixed to the bottom slat 2 with one or two or possibly more fastening elements 3 in order to insert the foot area 8 of the cladding elements 5 of a second row of cladding elements 35 arranged above them into the respective foot engagement section 26 of the fastening elements 3 and thereby the footer 8 of the second To be able to press the cladding elements 5 arranged in the cladding element row 35 against the head area 7 of the cladding element 4 arranged in the lowermost cladding element row 32 . The head region 7 of the cladding elements 5 in the second row 35 of cladding elements is then supported on a slat 2 arranged above the lowest slat 2 . The complete façade cladding 1 can be erected by repeated arrangement and fixing of further cladding elements 5 on an overlying third row of cladding elements 36 and optionally further rows of cladding elements. With the exception of the fastening screws 33 to be screwed into the bottom row of cladding elements 32, only a corresponding number of fastening elements 3 are required for fixing the cladding elements 4, 5 to the slats 2. However, a separate tool is not required. This is how the establishment of the in figure 4 exemplified facade cladding 1 particularly simple.

In figure 5 1 shows an example of a section of a facade or roof cladding 1 according to the invention in the area of a horizontally running slat 2, with the cladding elements 4, 5 having a head region 7 of a different configuration. The slat support leg 9 directed away from the outside 6 runs in a straight line up to its end region 10. Deviating from the cladding elements 4, 5, which are in the figures 1 , 2 and 4 are shown, the slat support leg 9 has no angled support end section 12 . A front edge 34 of the slat support leg 9 facing the upper side 11 of the slat 2 forms a support edge for the form-fitting installation of the cladding elements 4, 5 on the upper side 11 of the slat 2.

In figure 6 only schematically shows the possibility that exists with the facade or roof cladding 1 according to the invention that a single defective cladding element 4 can be detached from the composite of the cladding elements 4, 5 of the facade or roof cladding 1 and replaced by a new cladding element 4. A defective cladding element can be removed from the associated slat 2 and detached from the composite of the cladding elements 4, 5 without neighboring cladding elements 5 or fastening elements 3 being damaged as a result. In order to insert a new cladding element 4 in place of the damaged and removed cladding element in the assembly, the foot area 8 of the cladding element 5 arranged above the new cladding element 4 and overlapping it from above must first be pivoted slightly outwards from the slat 2 . The fastening element 3, with which the foot area 8 of the pivoted cladding element 5 was originally pressed and supported on the head area 7 of the cladding element arranged underneath and removed in the meantime, is reversibly deformed and bent open. The pivoted cladding element 5 is held at least in its head region 7 with a fastening element 3 that is hardly noticeably deformed on the slat 2 arranged above it.

The lining element 4 to be newly inserted can be introduced from below into the foot engagement section 26 of the fastening element 3 located underneath and with its The head area 7 can be pushed upwards along the front side 14 of the slat 2 between the slightly outwardly pivoted foot area 8 of the cladding element 5 arranged above it and pivoted until the head area 7 of the cladding element 4 to be newly inserted again overlaps the top side 11 of the slat 2 and is fixed to it can. The paneling element 5 that is located above it and pivoted can then be pivoted back again and the facade and roof paneling 1 can be closed. The fastening element 3 embraces the newly introduced head area 7 of the lining element 4 and returns to its original starting position, in which it engages with the foot area 8 of the lining element 5 arranged above and presses its foot area 8 against the head area 7 of the newly introduced lining element 4, and at the same time the foot area 8 of the upper paneling element 5 and the head area 7 of the newly introduced paneling element 4 resting thereon against the slat 2 . In figure 6 a state of the facade or roof cladding 1 during the insertion of the new cladding element 4 is shown shortly before the slat 2 reaches behind with the slat support leg 9 . The cladding element 5 arranged above it is pivoted slightly outwards in its foot area 8 . The cladding element 5 arranged underneath is not changed in its position or orientation during the insertion of the cladding element 4 and is fixed unchanged by the associated fastening element 3 on the batten 2 in question.
