Description

The invention relates to a fastening device for fastening a facade cladding element to a building facade.

It is known to disguise the facades of buildings with cladding elements. Here, for example, aluminum, glass or natural stone slabs can be used. Sheets of other materials are also possible. It is important that a stable attachment of the cladding elements takes place on the facade, so that they are not torn by external influences, such as strong winds or air turbulence, from the building. Furthermore, it is important to allow easy installation of the cladding elements on the facade. Furthermore, it is desirable to allow easy alignment of the cladding elements on the facade, which must be compensated inter alia tolerances of the facade.

DE 296 02 472 U1 describes a fastening device for facade panels with two engaging behind hook elements.

The object of the invention is to provide a fastening device for fastening a facade cladding element to a building facade, by which a simple and secure attachment of the facade cladding element is made possible.

The object is achieved according to the invention by the features of claim 1.

The fastening device according to the invention comprises a base profile which can be fastened to the building facade. This can be done for example by screws, which are passed through recesses in the base profile. Before the facade cladding element is installed on the facade of the building, the base profile is fastened to the building facade.

The fastening device according to the invention further comprises a cladding element profile, which has a connecting element for connecting to the cladding element. The joining of the cladding element profile with the cladding element can be done for example by gluing, so that the connecting element can be easily formed as an adhesive surface on the cladding element profile. A connection by screws or other fastening methods is also possible.

According to the invention, the base profile has a spring element which can be pressed in through the cladding element profile or the cladding cladding element in the direction of the base profile. Alternatively or additionally, the cladding element profile may have a spring element which can be pressed in through the base profile or the building facade in the direction of the cladding element profile. By this depressed spring element, a force on the cladding element profile or facade cladding element away from the base profile can be applied. In other words, the panel element profile and the facade cladding element connected to it are pushed away from the base element by the spring element. This is of course only with a depressed spring element, d. H. if the spring element has a bias.

According to the invention, the base profile has a first hook element and the lining element profile has a second hook element. The first and second hook elements are by a movement of the cladding element profile relative to the base profile in a direction parallel to the plane of the facade cladding element hooked into each other. In this movement, the first and the second hook element are moved towards each other. This movement takes place in the longitudinal direction of the base profile. As a longitudinal direction of the base profile thus that direction is defined in which to move the first and second hook element when hooking on each other. According to the invention, interlocking of the first and second hook element is only possible if the distance between the base profile and the covering element profile in the region of the first and second hook element is less than a predetermined maximum distance. In other words, interlocking is possible only if the trim element profile is close enough to the base profile. The base profile and the cladding element profile can be moved closer to each other in the region of the first and second retaining element only by a depression of the spring element, as determined by the predetermined maximum distance. In other words, it is necessary to press the cladding element profile against the spring force of the spring element in the direction of the base profile in order to achieve a distance between the base profile and the cladding element profile, which is smaller than the predetermined maximum distance.
When mounting the facade cladding element on the building façade this is thus pressed against the spring force of the spring element in the direction of the building facade and the associated base profile, so that the predetermined maximum distance between the base profile and the cladding element profile is exceeded. Then it is possible to move the first and second hook element in a direction parallel to the plane of the facade cladding element toward each other, so that the two hook elements are hooked into each other. The intertwining can be a telescoping of the two hook elements, with a gripping behind the two hook elements into each other. After the first and second hook element have been pushed into one another or interlocked, the facade cladding element is no longer pressed against the spring force of the spring element in the direction of the building facade. The spring element thus pushes the cladding element again a piece of the building facade away. By pushing away this, the engagement of the two hook elements takes place. The fastening device according to the invention has the advantage that it can be quickly and easily installed and yet allows a secure attachment of the facade cladding element to the building facade. For mounting, it is only necessary to press the cladding element with the cladding element profile against the spring force in the direction of the base profile and, for example, in a vertical facade in the pressed state a small piece to move down so that the two hook elements can interlock. For this purpose, a vertical displacement of a few mm is sufficient. This very small vertical displacement makes it possible, for example, to replace individual panels in a building facade, so that the surrounding panels not have to be removed. The required vertical stroke of a few mm can already be provided by the gap dimensions surrounding a facade cladding panel. Usually, a gap of a few mm width is provided around each cladding panel. Nevertheless, it can be ensured by the hook elements according to the invention that the cladding element remains securely connected to the building facade. According to the invention, the two hook elements are designed to engage behind the respective other hook element. This is done by one of the two hook elements having a region which is spaced from the cladding element profile, or the base profile, depending on which profile of this hook element is formed. At this spaced portion of the hook element is followed by a Hintergreifansatz, z. B. 3.5 - 4 mm in the direction of the cladding element profile or the base profile. The other of the two hook elements has a Hintergreifausnehmung or a second Hintergreifansatz. The Hintergreifansatz the first hook element can reach into a Hintergreifausnehmung the other hook element. Alternatively, the other hook element may have a second engagement lug behind which the first lug approach can engage.
By this engagement behind the base profile and the cladding element profile in a direction parallel to the plane of the facade cladding element can no longer be pulled apart. Thus, a release of the entanglement of the first and second hook element is prevented by pushing apart of the first and second hook member. A release of the entanglement is only possible by reducing the distance between the base profile and the cladding element profile in the region of the first and second hook element and by compressing the spring element. The yield of the Spring element here is preferably selected such that accidental compression of the spring element, for example, by a gust of wind is not possible. The embodiment just described is particularly suitable for fastening cladding elements on a horizontally extending building wall. Such a wall is also understood in the context of the invention as a building facade. In a horizontally extending building wall telescoping the two hook elements can not be guaranteed by gravity. Thus, it is necessary to prevent by other measures, a release of the cladding elements of the building wall. This can be done by the just described embodiment of the hook elements with the Hintergreifansatz.

It is further preferred that the first and second hook element are elongated and are displaceable relative to each other in the installed state along its longitudinal direction. This results in a displacement of the facade cladding element relative to the building facade along a first axis. A vertical building facade may be a horizontal axis. This first axis is perpendicular to the longitudinal direction of the base profile. The longitudinal direction of the first and second hook element thus also extends perpendicular to the longitudinal direction of the base profile.

Furthermore, it is preferred that the first and second hook element in the installed state in a direction perpendicular to its longitudinal direction and parallel to the plane of the cladding element relative to each other are displaced without the entanglement of the first and second hook element is solved by the displacement. Thus, a displacement of the cladding element takes place relative to the building facade along a second axis. A vertical building facade may be a vertical axis. The second axis is parallel to the longitudinal direction of the base profile.

In a further preferred embodiment, the base profile and / or the cladding element profile has a vertical stop element. This serves to limit a pushing together of the first and second hook element perpendicular to its longitudinal direction and parallel to the plane of the facade cladding element. In the case of a vertical façade, the pushing together along a vertical axis in the direction of gravity downwards takes place here. The first and / or the second hook element preferably form the vertical stop element.

Furthermore, it is preferred that the base profile and the cladding element profile have an adjusting device. In particular, this adjusting device has an adjusting screw and serves to limit a pushing together of the first and second hook element perpendicular to its longitudinal direction and parallel to the plane of the facade cladding element. Again, in a vertical building facade, limiting collapse along a vertical axis in the direction of gravity downward. The adjusting device can be formed, for example, in that one profile has an adjusting screw and the other profile has a shoulder against which the screw is pressed, provided that it is screwed into its thread. A particular embodiment of such an adjusting screw may be the adjusting screw described in the third embodiment of the present application. All the features described in the present application in connection with the third embodiment may also find application in the first invention.

By adjusting the adjusting device, the facade cladding element is aligned relative to the building facade. For a vertical building façade, alignment takes place along the vertical axis. Preferably, the vertical stop element does not limit the telescoping of the first and second hook elements vertically to their longitudinal direction and parallel to the plane of the cladding element, provided that alignment is performed by the adjusting device. Therefore, if the adjusting device is used for aligning, the vertical stop element preferably has no function.

The adjusting screw is preferably not used solely for the alignment of the facade cladding element relative to the building facade. In addition, it can also be used to fix the trim element profile relative to the base profile. For this purpose, the adjusting screw is screwed in so far that it is pressed against the approach in the opposite profile or possibly even screwed easily into this approach. A substantial height adjustment does not yet take place at this point. However, it is ensured by the contact of the adjusting screw with the approach of the opposite profile that the cladding element profile is no longer movable in a direction perpendicular to the longitudinal direction of the hook elements relative to the base profile. In the case of a vertical building façade, a vertical fixation of the facade cladding elements thus takes place through the adjusting screw. Furthermore, the adjustment screw prevents lateral displacement, d. H. a displacement of the trim element profile relative to the base profile along its longitudinal direction. In addition to the above-mentioned fixation in the vertical direction, limiting the displaceability perpendicular to the longitudinal direction of the hook elements takes place by the vertical stop element, provided that the adjusting screw is not tightened or for any other reason allows no fixation. The same applies to the horizontal stop elements described below for a displacement in the horizontal direction.

It is further preferred that the base profile and / or the cladding element profile have a horizontal stop element, by means of which the extent of displacement of the first and second hook element along its longitudinal direction relative to each other can be limited. This can To avoid that a mounted cladding element dissolves by a lateral displacement of the building facade.

According to a second embodiment, which does not belong to the invention, the second hook element of the cladding element profile is T-shaped. The second embodiment may have all the features of the first invention. In this case, a first part of this second hook element extends at a right angle away from the cladding element profile. Starting from the end of this first part, which faces away from the cladding element profile, a second and third part of the second hook element each extend in the opposite direction at a right angle to the first part, namely parallel to the cladding element profile. In the case of a vertical alignment of the cladding element and the cladding element profile associated therewith, the second hook element thus has the shape of a large T located on the side. In this case, the second and third part of this second hook element form those components which engage in the first hook element or a corresponding recess of the base profile in order to connect the base profile to the cladding element profile. The cladding element profile together with the cladding element can thus be rotated by 180 ° and be reconnected to the base profile without further changes. If, for example, in the first position a hooking together of the first hook element with the second part of the second hook element takes place after the 180 ° rotation, a hooking together of the first hook element with the third part of the second hook element. This offers the advantage that the same cladding element profile can be used for a plurality of orientations of the cladding element. The cladding element profile can thus be produced more cheaply.

According to the second embodiment, it is preferred that the T-shaped second hook element is formed by a double-layered sheet, which is folded at the end facing away from the cladding element profile end of the second hook element. This allows a greater stability of the second

Hook element can be achieved. In particular, it can be prevented that the second hook element bends along the longitudinal direction of the base profile. In this direction occur in most applications, the largest forces, so that here the greatest stability is required. In other words, the second hook element is formed as a double-layered T which is folded at its transverse top. The T-shaped second hook element is preferably flat.

It is further preferred that the T-shaped second hook element and in particular the second and third part of the second hook element extend in a plane which runs perpendicular to the cladding element profile along the longitudinal direction of the base profile.

Furthermore, it is preferred that the second and third part of the second hook element are configured for engaging behind the first hook element. This is achieved in that the second and third part of the second hook element each have a Hintergreifansatz extending in the direction of the cladding element profile. The first hook element has a Hintergreifausnehmung or a second Hintergreifansatz, in or behind which can reach into the first Hintergreifansatz.

Preferably, the T-shaped second hook element is formed symmetrically in the longitudinal direction of the base profile, so that depending on the orientation of the cladding element profile in relation to the base profile of either the second or the third part of the second hook element engages in the first hook element.

A third embodiment, which does not belong to the invention, also relates to a fastening device for fastening a facade cladding element to a building facade. Except for the T-shaped Forming the second hook member, this third embodiment has the same features as the second embodiment. All features related to

of the second embodiment can also be applied to the third embodiment. The third embodiment relates to a particular embodiment of an adjusting screw for aligning the facade cladding element relative to the building facade and in particular to its vertical orientation.

According to the third embodiment, the base profile or the cladding element profile has an opening into which an eccentric screw is screwed transversely to the longitudinal direction of the base profile and parallel to the cladding element profile. When the eccentric screw is rotated, the eccentric element of the eccentric screw abuts on a stop element of the other profile from the base profile and the cladding element profile. Thus, if the opening for the eccentric screw is formed in the base profile, the eccentric screw strikes against a stop element of the cladding element profile during its rotation. If the opening for the eccentric screw is formed on the trim element profile, the eccentric screw strikes against a stop element of the base profile during its rotation. This ensures that, by rotating the eccentric screw, the lining element profile is displaced relative to the base profile along the longitudinal direction of the base profile, preferably in the vertical direction. By twisting the eccentric screw thus the cladding element can be aligned with respect to the building facade. Preferably, the eccentric screw is arranged in an edge region of the facade cladding element, so that it can be easily reached and adjusted with a tool that is guided between two adjacent cladding elements. This tool is preferably a wrench, wherein the eccentric screw, for example, a screw head with a External hexagon can, which is positively connected with a corresponding wrench.

Under an eccentric screw according to the invention a screw understood that has an eccentric element which is eccentric in the radial direction of the screw. When the screw is turned, the radial extent of this eccentric element thus changes. This eccentric element is preferably in the region of the screw head, e.g. arranged directly below the hexagon socket.

In a preferred embodiment, the opening in the second hook element of the cladding element profile is formed, so that the first hook element of the base profile serves as a stop for the eccentric screw. The opening may, for example, be formed in the first part of the T-shaped second hook element described in the second embodiment, so that it is arranged in the immediate vicinity of the first hook element of the base profile.

Furthermore, it is preferred that the eccentric screw has at its eccentric element a projection which prevents further rotation of the eccentric screw beyond its position with the maximum eccentricity. If the eccentric screw were turned further beyond this position, this would lead to a sudden reduction in the eccentricity of the eccentric element, so that the base profile and the cladding element profile approach each other abruptly again. Such an undesirable effect can be prevented by the said projection in the eccentric element. Furthermore, it is preferred that the cladding element profile is glued to the cladding element. This is made possible in particular by the T-shaped configuration of the second hook element, since this ensures that the cladding element profile does not come off the cladding element.

In the following, preferred embodiments of the invention will be explained with reference to figures.

In Fig. 1a the fastening device according to the invention is shown in a partially sectioned side view. Here, only the part of the fastening device 10 in the region of the first and second hook element 24, 26 is visible.

In Fig. 1a the fastening device 10 is shown during assembly. This means that the hook elements 24, 26 are not yet engaged, but that the cladding element 12 is still a few mm above its intended end position. In Fig. 1 a is visible that during assembly, the cladding element 12 is pressed together with the cladding element profile 18 against the spring element 22 in the direction of the facade 14. The spring element 22 is in this case by a raised 42, which is formed in the cladding element profile 18, pressed.

In Fig. 2a is the cladding element profile 18, in the installed position. This means that the two hook elements 24, 26 are pushed into one another. In Fig. 2a the standard position is shown, ie the position in which no vertical adjustment by the adjusting device 36 has been made. A sliding down of the cladding element profile 18 is in this case prevented by the two stop elements 34, 35. The first stop element 34 is formed by a region of the second hook element 26 extending substantially perpendicular to the cladding element 12 and by a corresponding region of the first hook element 24 that is essentially parallel thereto. These areas are located in the Fig. 2a shown position on each other, so that the cladding element 12 can not be moved further down.

In Fig. 2a a fixing of the cladding element 12 takes place in the vertical and horizontal directions by screwing the adjusting screw 38 so that it is pressed against the projection 44 and thus prevents a vertical or horizontal movement of the cladding element profile 18 relative to the base profile 16.

However, the adjusting screw 38 is not screwed so far into the thread that the cladding element 12 is pushed upwards.

If the cladding element 12, for example, to compensate for tolerances in the facade or in the fastening device to be moved up, the screw 38, as in Fig. 3a shown, further screwed into the thread provided for this purpose of the cladding element profile 18, so that a force is applied to the projection 44, which is formed in the base profile 16 by this. This projection 44 has a substantially horizontally extending short end portion 46 and a sloping curved upper portion 48. These two Sections are in the FIGS. 4a and 4b to recognize more clearly. Due to the curved configuration of the section 48, the lug 44 can accommodate larger loads. This allows the base profile to be made of a low-strength material. Preferably, the base profile 16 and the trim element profile 18 are made of stainless steel having a thickness of 1 mm or less, preferably 0.9 mm or 0.8 mm.

By screwing in the screw, as in Fig. 3a Thus, the cladding element 12 has been moved upwards by a few mm relative to the facade 14, so that the two lugs 30 and 32 of the first and second hook element 24, 26 touch.

As in the FIGS. 1b . 2 B and 3b illustrated, the spring element 22 is preferably formed as a spring lip, which is wider at its profile-side end and tapers in the direction of its free end. The spring lip is thus trapezoidal. The sloping trapezoidal edge allows the installation of prefabricated panel corners, the corner profiles according to Fig. 4b can be used. In this case, a simultaneous hooking of the hook elements 24 and 26 takes place on both sides of the corner during assembly. This in Fig. 4b shown base corner profile in this case has no horizontal stop member to allow lateral displacement during corner mounting.

As in the FIGS. 1c . 2c and 3c illustrated, the base profile further comprises two in particular vertically extending horizontal stop members 40a, 40b. Between these stop elements, the covering element profile 18, a further Horitzontalanschlagelement 40 c is formed. This is designed as a substantially triangular bulge in the cladding element profile 18 and at the same time serves to stiffen the profile 18 in this area, in which a bonding preferably takes place with the cladding element 12. The cladding element 12 may be, for example, an aluminum, glass or natural stone slab.

The base profile 16 may for example have a length of 3 m. The cladding element profiles 18 can be glued, for example, in duplicate, each on a cladding panel 12. The adhesive bonding is in this case preferably carried out at each lateral end of the plate 12. A base profile 16 and a cladding element profile 18, each with a length of 3 m, can, for example, have one above the other 4 times the fastening device 10, which in the FIGS. 1 to 3 is shown. Thus, a stable attachment of very large and heavy plate elements are made possible on a building facade. The vertical distance between two hook elements 24 or 26 may be, for example, 800 mm.

This in Fig. 4a illustrated basic profile is used on straight sections of a facade 14 while the in Fig. 4b shown base corner 16 is attached to corners of a facade. Usually, a cladding panel 12 has a right and a left cladding element profile 18, in particular a plate profile. The right plate profile is here in Fig. 5b shown, while the left plate profile is designed to mirror this. For particularly wide cladding panels 12 may additionally in Fig. 5a represented plate profile are used for center support. This center profile can also be found in narrow plate strips 12 use.

In Fig. 6a a fastening device according to the second embodiment is shown in a partially sectioned side view. Here, only the part of the fastening device 10 in the region of the first and second hook element 24, 26 visible, wherein the cladding element profile 18 according to Fig. 6a has two vertically arranged one above the other second hook elements 26. The same applies to the first hook elements 24 of the base profile 16.

In the illustrated FIGS. 6 to 9 is both the T-shaped configuration of the second hook member 26 according to the second embodiment as also shown an eccentric screw 36.

In Fig. 6a the fastening device 10 is shown during assembly. This means that the hook elements 24, 26 do not yet engage in one another, but that the facade cladding element 12 is still arranged a few mm above its intended end position. In Fig. 6a is visible that during assembly, the cladding element 12 is pressed together with the cladding element profile 18 against the spring element 22 in the direction of the facade 14. The spring element 22 is in this case pressed in by the second hook element.

In Fig. 7a is the cladding element profile 18, in the installed position. This means that the two hook elements 24, 26 are pushed into one another. In Fig. 7a the standard position is shown, ie the position in which no vertical adjustment was made by the eccentric screw 36. A sliding down of the cladding element profile 18 is in this case prevented by the two stop elements 34, 35. The first and second stop elements 34, 35 are formed by a region of the second hook element 26 extending essentially perpendicular to the cladding element 12 and by a corresponding region of the first hook element 24 that is essentially parallel thereto. These areas are located in the Fig. 7a shown position on each other, so that the cladding element 12 can not be moved further down.

In Fig. 7a can a fixation of the cladding element 12 in the vertical and horizontal directions by screwing the eccentric screw 36 so that it is pressed against the projection 35 and thus prevents a vertical or horizontal movement of the cladding element profile 18 relative to the base profile 16. However, the eccentric screw 36 becomes not turned so far that the cladding element 12 is pushed upwards.

If the cladding element 12, for example, to compensate for tolerances in the facade or in the fastening device to be moved up, the screw 36, as in Fig. 8a shown further screwed into the space provided for this purpose threaded opening of the cladding element profile 18, so that a force is applied to the first hook member 24 by this. Preferably, the base profile 16 and the trim element profile 18 are made of stainless steel having a thickness of 1 mm or less, preferably 0.9 mm or 0.8 mm.

By screwing in the screw 36, as in Fig. 8a Thus, the cladding element 12 has been moved upwards by a few mm relative to the facade 14, so that the two lugs 30 and 32 of the first and second hook element 24, 26 touch. As in Fig. 8a Visible, the eccentric screw 36 has been rotated counterclockwise so far that the projection 100 abuts against the stop element 35 of the first hook member 24, so that further rotation of the adjusting screw counterclockwise is no longer possible. The eccentric element 36a of the eccentric screw 36 has thus reached its maximum eccentricity, so that the cladding element profile 18 can not be further moved by the eccentric screw 36 from the base profile 16 away. At the same time it can be prevented that the eccentric screw 36 is rotated too far and the cladding element profile falls in the direction of gravity back down.

As in the FIGS. 6b . 7b and 8b illustrated, the spring element 22 is preferably formed as a spring lip, which is wider at its profile-side end and tapers in the direction of its free end. The spring lip is thus trapezoidal.

The cladding element 12 may be, for example, an aluminum, glass or natural stone slab.

As in Fig. 9 is visible, the eccentric screw 36 is located in the edge region of the cladding element 12 and can therefore be easily reached and adjusted by a laterally guided past the cladding element wrench. Furthermore, in Fig. 9 in each case two stiffening elements 102a, 102b, which are formed in the outer lower region of the first hook element 24. These are each formed by a bead-shaped thickening in this first hook element 24, so that this hook element can absorb higher loads.

In Fig. 10a various embodiments of an adhesive variant of the cladding element profile 18 are shown. In cross-section, this cladding element profile 18 is L-shaped, wherein that leg in which the hook element 26 is formed, is formed by a folded sheet double-layered.

Depending on the length, depending on the length of the facade cladding element 12 to be fastened, the cladding element profile can have different lengths, whereby depending on the length, a different number of hook elements 26 per cladding element profile 18 can be provided. The bonding of the cladding element profile 18 with the cladding element 12 takes place on the second leg of the L-shaped profile 18th

Again Fig. 9 can be removed, the cladding element profile 18 on a first leg 18a which extends substantially parallel to the cladding element, and a substantially perpendicular thereto extending second leg 18b. By the second leg 18b of the first leg 18a at a distance of a few millimeters, for example 3 mm, held by the cladding element 12. In the resulting space between adhesive 23 can be applied, through which a bond the cladding element profile 18 with the cladding element 12 takes place. This can ensure that a consistent amount of adhesive is always used.

In order to ensure a sufficient supply of air to the adhesive, the second leg 18b on its side facing the cladding element 12 side recesses 19. Further recesses 21 may be formed on the first leg 18a. This is particularly advantageous when using two-component adhesive. The recesses allow this the necessary access of the second component, which may be, for example, humidity or UV light. Furthermore, the recesses allow a visual inspection and / or a machine control of the order of the adhesive. The use of liner is no longer necessary.

The recesses may for example have a width of 1.5 mm. Due to a small width of the recesses, the exit of a viscous adhesive can be limited approximately to the outer edge of the cladding element profile 18.

Fig. 10b shows another embodiment of a trim element profile 18, which can be connected via a bolt with the cladding element 12. In this case, far the cladding element profile 18 a bulge 104, which is directed in the direction of the cladding element 12. This bulge 104 engages with mounted trim element profile 18 in a corresponding recess, not shown in the cladding element 12 and thus prevents rotation of the cladding element profile 18 relative to the cladding element 12. Such twisting must be prevented because 26 introduced forces on the side of the profile 18 hook element which would cause a twisting of the profile 18.

In the FIGS. 11a to 11d different views of an embodiment of the eccentric screw 36 are shown. The eccentric screw 36 has an eccentric element 36a, which is formed directly below the hexagon socket 104 on the screw head. The thread 108 does not immediately start below the screw head. Rather, an intermediate region 106 is provided which has no thread and which preferably extends over a length of 3 mm. As in Fig. 11a visible, this intermediate portion 106 is at an eccentric screw 36 which is screwed into the L-shaped cladding element profile 18, in the region of the recess 37, while the thread 108 is already on the in Fig. 6a right side of the cladding element profile 18 is located. The thread preferably has a pitch of 45 °. The opening 37 in the trim element profile 18 may have a diameter of 5 mm.

The base profile 16 may for example have a length of 3 m. The cladding element profiles 18 can be glued, for example, in duplicate, each on a cladding panel 12. The adhesive bonding is in this case preferably carried out at each lateral end of the plate 12. A base profile 16 and a cladding element profile 18, each with a length of 3 m, can, for example, have one above the other 4 times the fastening device 10, which in the FIGS. 6 to 8 is shown. Thus, a stable attachment of very large and heavy plate elements are made possible on a building facade. The vertical distance between two hook elements 24 or 26 may be, for example, 800 mm.

FIGS. 12a to 12e illustrate a displacement assurance element 110 that may be used in a preferred embodiment of the invention. Again Fig. 12c can be removed, this shift securing element 110 and its pointing away from the base profile 16 leg between the two legs of the double-layered in this section cladding element profile 18 is arranged. Preferably, the Leg held here clamped. The displacement securing element 110 is preferably pushed between the two legs of the cladding element profile 18 before the plate assembly, after which the cladding element can now be aligned horizontally and, if necessary, vertically aligned, for example by the illustrated eccentric screw 36. The angular displacement securing element 110 is now fixed to the base profile 16, for example with a self-tapping screw. The cladding element is thus fixed at least in the horizontal direction. Thus, there can be no horizontal displacement of the cladding element profile 18 relative to the base profile 16, ie no displacement perpendicular to the longitudinal direction of the base profile 16.

Depending on the height in which the displacement securing element 110 is inserted into the cladding element profile 18, a vertical fixation of the cladding element profile 18 may further take place, so that a release of the entanglement of the two hook elements 24, 26 can be avoided. This situation is in Fig. 12d shown in that is visible that the displacement securing element 110 abuts a shoulder of the cladding element profile 18, so that a displacement of the cladding element profile 18 in Fig. 12d to the top is no longer possible.

According to Fig. 12e The displacement securing element 110 can also be arranged slightly higher. For example, it may have a vertical distance of 10 mm to said approach of the cladding element profile 18, so that a vertical displacement of the cladding element profile 18 relative to the base profile 16 is still possible. In this case, only one horizontal fixation, ie a fixation perpendicular to the longitudinal direction of the base profile 16, takes place by means of the displacement securing element 110 Fig. 12e Thus, the entanglement of the two hook elements 24, 26 could still be solved. The illustrated anti-slip element is particularly suitable for horizontal building facades or ceilings, as there is a simple and secure fixation of the cladding element on the facade allows. Possibly. Here, a plurality of displacement securing elements 110 can be used.
