The resilient part comprises a plate, piece made from wire, or a dish-shaped profile.

Description

Technical field

The present invention relates to a facade construction according to the preamble of claim 1.

In the case of facades, a large number of plate-shaped components, which form the facade surface in the final state, are usually fastened to a lattice structure made of so-called posts and transoms, which form the supporting structure. For this purpose, the plate-shaped elements, for example metal or glass plates, are enclosed in suitable frames or provided with support profiles, on which sections are formed, via which the attachment to the support structure takes place.

State of the art

Such a facade construction is known from DE 42 06 345 A1 and has several glass panes, the edge of which is encompassed by a holding profile. The holding profile is, for example, in engagement with the chamfered edge of the glass pane by a bevel and is fastened to a support structure in a direction perpendicular to the panes by a plurality of fastening elements. In particular, the fastening elements engage in a suitably designed section of the holding profile, so that by means of of the holding profile, the glass panes are fixed to the supporting structure.

It is known in the art to glue the holding profile to the edge of the glass pane, but this is comparatively complex. If, on the other hand, such an adhesion is not provided, there is a risk that the holding profile will come loose from the edge of the glass pane when the structure is moving or thermally caused deformations. This can only be prevented by the comparatively complex gluing of the holding profile to the glass pane. If in this case the fastening is carried out by means of the fastening element in such a way that no movement is permitted for the glass pane, then this is subject to constraints and the like as a result of the building movements mentioned. At the same time, a largely loose fastening of the glass pane is likewise not expedient and does not meet the safety requirements, so that known facade constructions are in need of improvement in this regard.

From DE 41 26 918 A1 an arrangement of mounting profiles for fastening a glass pane is known, by means of which rotary movements of the edge of the glass pane about an axis parallel to the edge as a result of wind suction forces which act on the glass pane can be absorbed.

Furthermore, a frame for a window is known from EP 0 576 867 B1, in which the edge of the respective glass pane is gripped by a holding profile.

The German laid-open specification 42 06 345 describes a facade construction with a holding profile which lies against the bevelled edges of the glass panes. Sealing strips are additionally arranged between the holding profile and the bevelled surfaces. The holding profile is rigid and can be a relative movement of the adjacent Do not catch the glass panes away from each other so that the glass panes can slide out.

The German utility model 296 01 640 shows a spring part that is temporarily attached when the facade construction is being assembled. The spring part is only used on one side using a bearing to support the glass pane.

US 4,854,098 describes a facade construction with a holding profile which surrounds the edge of two glass panes arranged adjacent to one another. A holder is biased into an engagement position by an elastic element so that it engages behind the inner edge of the plate-shaped component. The elastic element made of metal can be anchored in the metal profile. In this case, however, the fastening element for holding the glass pane and the spring element are one and the same component, while in the other embodiments of US Pat. No. 4,854,098 these tasks are performed by different components. The spring element only acts on one of the two adjacent glass panes. US 4,854,098 represents the closest prior art.

Presentation of the invention

The invention has for its object to provide a facade construction that is simple, and in which plate-shaped components, in particular glass panes, are fixed to a support structure via holding profiles such that both a reliable absorption of the wind forces and the dead weight of the glass panes, as well secure attachment in a direction parallel to the pane surface is possible.

This object is achieved by the facade construction specified in claim 1.

Accordingly, the facade construction according to the invention is characterized in that a fastening element has a spring element which is designed to be resilient parallel to the plane of the plate-shaped components, in particular glass panes. The spring element is designed in such a way that the holding profile is held and fixed in the effective direction of the spring element, that is to say parallel to the disk surface, with a prestress under a permanently maintained contact pressure. In other words, the spring element always presses the holding profile onto the edge of the glass panes. For this reason, the holding profile can be made particularly small, so to speak miniaturized. Furthermore, the holding profile according to the invention does not necessarily have to be glued to the edge of the glass panes. Rather, what is described provides

Spring element so that the holding profile cannot slip off the edge of the pane. For this reason, it can be made particularly small. The comparatively large design of the holding profile, which is usually required for a firm connection to the edge of the pane, is advantageously avoided. Therefore, the holding profiles are held securely on the edge of the glass pane in a simple manner and also during building movements and other deformations.

Because of the prestress acting between the spring element and the holding profile, the retention of the holding profile on the edge of the glass panes is also ensured in the event that the glass panes "want" to be removed from the holding profile as a result of structural movements or deformations. The bias acting in the spring element according to the invention ensures that the holding profile follows the movement of each glass pane, in particular in the direction away from the spring element, and remains securely on the edge of the glass pane.

In addition to this advantageous effect of the pre-tension formed between the spring element according to the invention and the holding profile, the spring element also has the advantage that movements of the glass pane in the opposite direction, that is to say in the direction of the holding profile, can also be compensated for. As mentioned, in the constructions known in the prior art, there may be constraints if the glass pane is fixed rigidly in a direction parallel to the pane surface. In contrast, the spring element according to the invention is able to cushion such movements, so to speak, so that no constraining forces arise in the glass panes. The construction described is simply constructed in that a comparatively small, narrow frame can be used as the holding profile, which, in the case of a facade element made of glass, only has two glass panes arranged at a distance from one another the outer pane must be inserted. The spring element provided according to the invention, which serves to absorb movements in directions parallel to the disk surface, can also be made extremely simple in all of the preferred embodiments described below.

The fixing of the glass panes via the small holding profiles in the direction perpendicular to the pane surface takes place in a conventional manner by means of suitable fastening elements which are in engagement with a section of the holding profile. For this purpose, part of the frame is provided with a section by means of which it can be fixed in a direction perpendicular to the pane surface. According to the invention, a spring element is additionally provided which, as mentioned, is flexible in a direction parallel to the disk surface. It should be noted that the fastening element and the spring element can be integrated into a single component.

Preferred embodiments of the facade construction according to the invention are described in the further claims.

For an advantageous sealing of the entire construction, it is preferred that a sealing material is arranged between the holding profile and the edge of the glass pane.

Although it is not necessary for the implementation of the basic idea of the invention, the holding profile can be glued to the edge of the glass pane. This is advantageous in certain applications, but according to the invention the prestressing acting between the spring element and the holding profile already ensures that the holding profile remains securely on the edge of the glass pane. In the area of contact between the holding profile and the edge of the glass pane, all that is required is an intermediate or Introduce sealing material that prevents the ingress of dirt.

For the engagement between the holding profile and the edge region of the disc, it has proven to be advantageous to form the edge of the disc at an angle, so that a section on the holding profile is designed in a corresponding manner at an angle, so that thereby a secure engagement with the Edge of the glass pane and a secure mounting of the glass pane is achieved.

Similarly, it is conceivable to provide the edge of the glass sheet with a step or a groove which is formed on the outermost edge and parallel to this, so that a largely U-shaped section of the holding profile can grip around the edge of the glass sheet and on Because of the groove or the step on the front surface of the glass pane can be arranged flush. This offers advantages with regard to the appearance of the glass facade and can be combined in particular with a black anodized holding profile in such a way that the holding profile hardly stands out visually from the glass pane.

It has proven to be advantageous for the spring element to have a disk-shaped design. The spring element can basically consist of a suitable resilient material, for example metal or plastic. Particularly good properties result for a disk-shaped spring element if it is provided with at least one recess in the edge area, so that it has the required spring properties in the edge areas adjacent to the holding profiles. The contour of such a recess can for example run parallel to the edge, so that a resilient eyelet is formed to a certain extent. In particular for the use of metal for the fastening and spring element, it is preferred that the recesses together with the edges of the Define spring fasteners. In other words, the recess extends along the edge in the resilient sections to within a few millimeters of the edge, so that, according to this preferred embodiment, a resilient metal bracket remains in the edge area, which can absorb the movements and expansions.

For the spring element, an embodiment has also proven to be advantageous in which it is made of wire and is provided with resilient eyelets by suitable shaping of the wire. The resilient eyelets bear against the holding profile under pretension in such a way that the holding profile remains securely at the edge of the glass pane and a resilient mounting of the glass element in the direction of the pane surface is achieved.

The spring element can also be designed as an elongated profile, which has a largely trough-shaped cross section, and whose free legs are resilient on the central section.

The design of the resilient sections can be achieved in a particularly favorable and simple manner in that recesses are formed in the combined fastening and spring element in those areas which are in contact with sections of the plate-shaped components. These recesses are designed depending on the material used. The connection between the respective material, for which both metal, in particular stainless steel or aluminum, and high-strength plastic is possible, with suitably designed recesses defines the properties of the respective spring section. For example, when using high-strength plastic for the combined fastening and spring element, the recesses can be designed in such a way that a wall thickness in the range of approximately 1 cm remains between a respective recess and the edges of the component, so that for the resulting one Spring section in view of the elastic modulus of plastic, which is a fraction of that of metal, favorable spring properties can be achieved.

Particularly soft spring properties can be obtained by providing a slot from a recess formed to the edge of the component, so that a resilient bracket is formed on the fastening and spring element.

Both this embodiment and the formation of resilient eyelets can be achieved by shaping a stainless steel wire into a suitable shape.

Plastic and metal have proven to be favorable as materials for both the fastening element and the spring element. The two elements can each consist of only one of the two materials, with high-strength plastic, stainless steel and aluminum being preferred. In the case of a combination of materials, a metal insert is preferred as a fastening element in a spring element made of rubber.

In order to meet fire protection requirements, the fastening arrangement according to the invention can advantageously be supplemented by a washer made of metal, which provides a fireproof fuse in particular when using high-strength plastic or stainless steel wire for the fastening and spring element.

Finally, to simplify the construction, it is preferred that the spring element described and the fastening element, which ensures the fixing in the direction perpendicular to the glass pane, are formed in one piece. In other words, the integrated fastening and spring element firstly secures the glass pane by engaging with a section of the holding profile on the support structure in the direction perpendicular to the glass pane. The one-piece fastening and spring element is on the other hand designed in a novel manner in the direction parallel to the glass pane, so that on the one hand compensating movements are possible in this direction and on the other hand the holding profile is held securely on the edge of the glass pane.

Detailed description of preferred embodiments of the invention

Fig. 1 shows in section the area between two glass elements 10 of a facade, which are fixed by a common fastening element 12 on a (not shown) support structure. Of the support structure, only one screw channel 14 is indicated in FIG. 1, which is formed on a facade profile which, together with other profiles, forms the support structure. A fastening screw 16 is screwed into the screw channel such that the fastening element 12 is fastened to the (not shown) profile of the supporting structure with the interposition of an intermediate element 18.

The glass elements 10 are fastened in that the disk-shaped fastening element 12 engages in a U-shaped section 20 of a holding profile 22. The holding profile 22 is largely S-shaped and encompasses a portion 24, which is formed obliquely in the embodiment shown, the edge of the respective glass sheet 26. This is the outer glass sheet 26 of the respective glass element 10. As in the Fig. 1 is also indicated, between the portion 24 of the retaining profile 22 encompassing the glass pane edge and the edge of the glass pane, a sealing material 28 which largely prevents the passage of steam and water between the inside and outside of the facade.

It should be noted that, in addition to the seal 28, no gluing of the respective pane edge to the holding profile 22 is required. Rather, the fastening element 12 is designed to be resilient in such a way that the respective holding profile 22 is always pressed against the edge of the glass pane 26 even without gluing. This is in the embodiment shown achieved in that a recess 30 is provided in each of the two lateral edge regions of the fastening element 12, that is to say in the regions which extend into the U-shaped section 20 of the holding profile 22. In a plan view, the fastening element accordingly has, for example, a single larger cutout in the two sections mentioned, the contour of which follows the lateral edge of the fastening element 12, so that 12 spring lugs are thereby defined on both sides of the fastening element.

The two glass panes 26 are attached via the holding profiles 22 in such a way that the spring eyelets of the spring-shaped fastening element 12 are prestressed under pressure. As a result, the resilient fastening element 12 applies a compressive force to each of the two holding profiles 22 arranged laterally therefrom, which points in the direction of the glass pane 26 held in each case, so that the holding profile remains securely on the glass edge even without any adhesive bond being formed towards it. This applies in particular also in the event that building movements occur in which the glass elements 10 move away from the attachment point shown. The resilient fastening element 12 pushes the respective holding profile 22 to a certain extent following such a movement of the glass element 10 in the same direction.

If, on the other hand, building movements occur in which the glass elements 10 move in the direction of the fastening point, this does not result in any constraining forces in the glass elements 10 either. Rather, the resilient fastening element 12 can yield in its edge regions in a direction parallel to the disk surface, that is to say from right to left and vice versa, as shown in FIG. 1, so that constraining forces are avoided even in this direction of movement.

2 shows a further embodiment of the invention, which is varied both with regard to the design of the holding profiles 22 and the resilient fastening element 12. As in the embodiment of FIG. 1, the holding profile 22 is initially provided with a U-shaped section 20. In the embodiment of FIG. 2, this section 20 is followed by a further U-shaped section 32 such that the upper leg of section 20 (as shown in FIG. 2) coincides with the lower leg of section 32, so that there is an overall S-shape for the holding profile 22. This S-shape can be seen for the holding profile 22 shown on the right in FIG. 2, while the holding profile 22 shown on the left has the mirror-image shape.

In accordance with the design of the U-shaped section 32 instead of the bevel 24 of the embodiment from FIG. 1, in the embodiment from FIG. 2 the respective glass pane 26 is not bevelled in its edge region, but rather is provided with a groove 34 which extends up to extends to the edge of the respective glass pane 26, so that a step is formed to a certain extent in the edge region. 2, the upper leg of the U-shaped section 32 engages in such a way that a largely flush surface results. As in the embodiment of FIG. 1, sealing material 28 is arranged between the respective holding profile 22 and the edge of the glass pane 26. By means of the resilient fastening element 12 described below, the respective holding profile 22 is always held firmly on the edge of the glass pane 26 even in this embodiment, even if these two elements are not glued to one another.

For this purpose, the resilient fastening element 12 in the embodiment shown in FIG. 2 is designed as a wire element, of which only individual sections can be seen in the sectional illustration. In essence it is Wire element formed around the screw 16 in a loop, and from this middle loop two spring lugs formed from the wire extend to the left and right as shown in FIG. 2. The design of such a spring element follows from FIGS. 6 to 15 and the associated description.

Due to the design of the lateral spring eyelets, the respective outermost lateral edge section bears against the middle leg of the U-shaped section 20 which runs vertically as shown in FIG. 2. As mentioned, the attachment is provided such that it takes place with the effect of a prestress between the resilient fastening element 12 and the respective holding profile 22, so that this is always reliably pressed onto the edge of the glass pane 26, and any movements of the glass pane 20 in the direction of the Fastening screw 16 can not lead to constraining forces, but are resiliently received by the fastening element 12. In the embodiment of FIG. 2, an additional disk 36 is also provided for better holding of the fastening element 12 formed from wire. In accordance with the embodiment shown in FIG. 1, the fastening screw 16 extends through an intermediate element 18 into the screw channel 14 of the support profile 38 of the facade construction indicated in FIG. 2.

This structure also applies to the embodiment of the invention shown in FIG. 3, in which case the holding profile 22 only corresponds to the previously described embodiments with regard to the U-shaped section 32 encompassing the edge of the glass pane 26. The glass panes 26 are fixed in a direction perpendicular to their surface in the embodiment of FIG. 3 via respective webs or projections 40, which extend parallel to the two free legs and opposite to the two free legs on the holding profiles 22 are provided. In the embodiment of FIG. 3, these sections 40 are held by the screw 16 by means of a fastening element 42, which has the trough-shaped or U-shaped cross-section which can be seen in FIG. 3 and has resilient lateral legs and extends perpendicular to the plane of the drawing. As can be seen in the drawing, the central leg of the U-shaped profile 42, which runs horizontally in FIG. 3, holds the two projections 40 to the profile 38 via the intermediate element 18. This attachment serves to absorb loads that extend perpendicularly to the pane surface in a direction away from it, as is the case, for example, in the case of wind suction forces.

The two lateral legs 44 of the profile 42 are designed to be resilient in such a way that movements are possible in a direction parallel to the glass pane surface. In this embodiment too, the attachment is carried out by means of the profile 42 in such a way that a prestress acts between the resilient legs 44 and the two holding profiles 22, which ensures that the two holding profiles 22 remain securely on the edges of the glass pane 26. The resilient design of the legs 44 also has the effect that, as has already been described in the previous embodiments, movements of the glass panes 26 can be absorbed parallel to their glass pane surface and in the direction of the fastening element 42, so that in the glass panes 26 also Movements in the building or other deformations can be avoided.

This also applies to the embodiment shown in FIG. 4. The fastening profile 42 is shown in the upper part of FIG. 4 in the initial state. As can be seen for this profile 42, in the initial state the two lateral legs 44 extend further outwards than the two holding profiles 22 shown in the lower part of FIG. 4 Facade construction with their inner sections are spaced apart. This means that when the profile 42 is pressed in between the two holding profiles 22 in the direction of arrow A, the two laterally formed legs 44 each pivot inwards, so that they are pretensioned in the attachment state shown in the lower part of FIG. 4 apply the two holding profiles 22. Similar to the embodiments of FIGS. 2 and 3, these encompass the respective edge of the glass pane 26, which in the case of FIG. 4 has no groove. Thus, in the embodiment of FIG. 4 there is no step from the holding profile 22 in the direction of the glass pane surface.

In addition to the prestressed and resilient fastening of the glass plates 26 in a direction parallel to the glass surface, in the embodiment of FIG. 4 the attachment is carried out in a direction perpendicular to the glass surface by respective largely S-shaped profiles 48, which have the U-shaped sections the holding profiles 22 are optionally connected in one piece. A section of each of the profiles 48 (corresponding to section 40 according to FIG. 3) extends inwards so that it can be fixed in a direction perpendicular to the glass pane surface by means of screw 16 holding profile 42 via a further intermediate element 50 the inwardly extending sections of the profiles 48 and an intermediate element 18 are fixed to the screw channel 14.

In addition to this definition in the direction perpendicular to the glass pane surfaces for receiving the wind loads, the attachment is carried out in a resilient manner parallel to the glass pane surfaces in the direction of the indicated arrows B, the preload acting between the fastening profile 42 and the two holding profiles 22 for a secure retention of the holding profiles 22 the respective edge of the glass pane 26 provides. The mounting arrangement consisting of the elongated fastening profile 42, which extends perpendicular to the plane of the drawing, and the plurality of fastening screws 16 are finally covered by a profile 52. It should also be mentioned that the formation of the profile 48 with a section extending inwards in the direction of the fastening screw 16 means that no stepped glass has to be used for the two glass elements 10, that is to say that the outer glass pane 26 extends as far as that inner glass pane 54 extends in the direction of the fastening screw 16. This considerably simplifies production.

This advantage also applies to the embodiment shown in FIG. 5, which results from the embodiment shown in FIG. 4 by a combination of the fastening profile 42 and the intermediate element 50, which ensures the fixing in a direction perpendicular to the glass pane. As indicated in the upper part of Fig. 5, it also applies to the one-piece resilient fastening profile that the lateral legs 44 extend further outwards in the initial state than the distance between the two holding profiles 22, so that these legs after the insertion of the fastening profile in the direction of arrow A resiliently and under tension on the two holding profiles 22. In contrast to the embodiment shown in FIG. 4, the fastening profile has, in addition to the U-shaped region with the two resiliently designed legs 44, two sections 56 which extend largely perpendicular to the glass surfaces and which, as in the embodiment shown in FIG Fix the inwardly extending portions of the profiles 48 worry. Here, the fastening screw 16 extends, as in the previously described embodiments, into a screw channel (not shown in FIG. 5).

The embodiment of FIG. 5 results in a particularly simple design of a resilient fastening profile, on the one hand by means of the sections 56, which are angled at the lower edge according to FIG. 5, provides for fastening the glass elements 10 in a direction perpendicular to their glass surfaces, while the glass elements are fixed in the direction parallel to their glass surfaces by the resilient legs 44, so that in this Movements in the direction are possible in order to avoid constraining forces in the glass elements 10, at the same time the prestressing of the resilient legs 44 acting on the holding profiles 22 ensures that these holding profiles 22 remain securely on the edge of the respective glass pane.

In FIG. 7 it can be seen which measure in the areas 126 results in an attachment of the plate-shaped components in the direction of the facade surface. For this purpose, the combined fastening and spring element 12 is shown in a top view. It is understood that, as can be seen in FIG. 6, it is designed in the form of a plate or disk and has a thickness of approximately 0.5 mm to a few millimeters, depending on the material. According to the orientation of the fastening element 12 shown in FIG. 7, in the final state it rests with its left and right spring sections 126 on sections of the plate-shaped components to be fastened or their profiles. The spring sections 126 are designed to a certain extent as "ears" which result from the formation of two respective comparatively large, for example oval, cutouts 130 in the edge regions. The edges of the fastening element 12 are at least partially adapted to the shape of the cutouts 130, so that a resilient metal bracket formed on the side results as the respective spring section 126. In this embodiment, the combined fastening and spring element 12 can be produced in one piece as a stamped part, for example made of stainless steel or aluminum.

As will be explained in more detail below, the fastening takes place in a direction perpendicular to the facade surface via the area 132 within the resilient sections 126 due to the above-mentioned overlap, while the resilient areas 126 are in contact with the plate-shaped components in such a way that movements parallel to the facade surface ( can be recorded in the direction of arrow C). It should also be noted that the central recess 134 is used for the passage of a fastening screw, and that a recess 136 is provided on the upper and on the lower edge of the fastening element 12, which allows a tool to be attacked. The tool serves to rotate the fastening element 12 about an axis which, as shown in FIG. 7, extends perpendicular to the plane of the drawing in order to bring it into its final state shown in FIG. 6, in which the area 132 has the sections 120 on the profiles 22 covered.

As shown in FIG. 8, the spring clip 126 formed laterally in this embodiment can also be provided with a slot 138, so that a softer spring characteristic results. In this embodiment too, the fastening and spring element 12 can be produced in one piece as a stamped part.

FIG. 9 shows a section through a section of a facade system using the fastening and spring element 12 according to FIG. 7. In an arrangement comparable to the illustration in FIG. 6, a plate-shaped component 112 is attached to a support profile (not shown) via a profile 22 through the fastening element 12 according to the invention with the aid of a fastening screw 16. As can be seen in the sectional view of FIG. 9, between the head of the fastening screw 16 and the fastening element 12 there is additionally a washer 140 made of metal, which is the Receiving an elastic cover profile 142 is used. With the interposition of this washer 140, the fastening screw 16 presses the combined fastening and spring element 12, which is in engagement with a leg 120 of the profile 22, to the left, as shown in FIG. 9, against the support profile (not shown). As a result, the fastening described is achieved in a direction perpendicular to the surface of the plate-shaped component 112.

As can also be seen from FIG. 9, the fastening and spring element 12 is by no means rigid due to the formation of the recess 130 in its edge region in the direction parallel to the surface of the plate-shaped component 112, but rather allows the spring clip 126 to spring in the direction of the Arrow C movements in this direction. As a result, the plate-shaped component 112 can expand or move in this direction, and the flexibility of the spring section 126 permits such changes in position so that no undesirable stresses can arise in the components. Finally, the arrangement is covered by a silicone profile 142. Furthermore, both the embodiment of the invention shown in FIG. 9 and all of the embodiments discussed above and below allow the application of a pretension to the glass holding frame 22. This pretensioning ensures that the glass holding frame 22 also during the described movements of the plate-shaped component 112 in The direction of arrow C remains securely on the edge of the component, that is, on the edge of the glass pane in the case shown. This remaining is ensured by the prestressing, even if the frame 22 is not glued to the edge of the glass pane, but rather only the seal (shown in black) is arranged between these two elements. Otherwise, with regard to the pretension acting between the frame 22 and the spring element in the attached state and with regard to the effects thereby achieved, the explanations given above in connection with FIGS. 1 to 5.

FIG. 10 shows a top view of an embodiment of the combined fastening and spring element similar to the first embodiment, but which is made of high-strength plastic. For the fastening element 12 made of plastic, it is fundamentally conceivable that it has sufficient spring properties completely without recesses 130 in order to absorb the expansions and movements described. With regard to its shape, the fastening element 12 shown as an example is, however, similar to the embodiment of FIG. 6. In the example shown, recesses 130 are provided which are smaller than those of the embodiment shown in FIG. 6 made of metal. In the embodiment of FIG. 10, a significantly larger wall thickness remains between the respective recess 130 and the edge of the fastening and spring element, so that due to the significantly lower elastic modulus of plastic than that of metal, suitable spring properties are achieved due to the larger recesses. In this case, too, the resilient eyelets 126 can be provided with the required spring properties by a suitable choice of the recess 130. Furthermore, the fastening and spring element 12 shown in FIG. 10 is also made in one piece from plastic. The additionally provided metal washer 140 indicated in FIG. 10 prevents the facade elements from falling out in the event of a fire.

The embodiment of the combined fastening and spring element shown in plan view in FIG. 11 is designed as a suitably shaped stainless steel wire. In this embodiment too, the fastening element 12 has, as it were, laterally formed “ears” which define the spring sections 126. Since in this case the fastening element 12 covers the area between two components to be fastened only to an extremely small extent 10, a metal washer 140 is additionally provided, as in the case of the embodiment of FIG.

As can be seen in particular from the sectional view of FIG. 12, the arrangement of fastening element 12 and washer 140 can additionally be covered by a silicone profile 142, which can also be seen in FIG. 9. The stainless steel wire shown in FIGS. 11 and 12 is of a suitable material thickness and suitably shaped, so that in this embodiment, too, plate-shaped elements are securely fastened in a direction perpendicular to the facade surface, while the lateral spring clips 126 compensate for movements in parallel to the facade surface is possible.

FIG. 6 additionally shows a modification of the embodiment from FIG. 11. Here, a stainless steel wire is shaped in such a way that there are two lateral spring clips 126, each having a free end, so that the overall configuration corresponds to the slotted cutout according to FIG. 8. In the area of the fastening screw 16, the fastening element 12 is shaped into an eyelet in the form of the stainless steel wire, so that the fastening by means of the screw 16 and the plate 140, which is also placed in this case, is made possible as a washer.

13 shows a combined fastening and spring element 12 in a two-part variant. On the one hand, this consists of the spring element 126, whose outer contour is comparable to the element shown in FIG. 10. The spring element 126 is made of rubber or high-strength plastic and has no cutouts in the case shown. With a suitable choice of material, it is designed to be resilient in particular in its edge regions (arranged laterally according to the illustration in FIG. 13).

In this case, the fastening element is formed by a metal insert 154, which to a certain extent corresponds to the area 132 (see FIG. 7) that does not recess and in the final state covers the sections 120. The metal insert 154 is provided with a suitable width B for this purpose. A resilient area remains over a width b between the respective edge of the metal insert 154 and the respective lateral edge of the spring element 126. The width B of the metal insert 154 is in particular selected such that even components 112 that have migrated to the outside are covered in the edge regions described by the metal insert 154, so that both the loads resulting from wind suction and the requirements with regard to fire protection can be met is done.

14 additionally shows that the metal insert 154 has a smaller material thickness than the spring element 126 made of rubber, and that it is completely covered by the spring element 126 on both surfaces. This embedding leads to handling advantages for the resulting combined fastening and spring element. However, the two components could also be formed separately, or the metal insert 154 could be flush with one of its surfaces in the spring element 126.
