Description

The invention relates to a fastening system for fastening panel-shaped facade elements with at least one holding element fastened to one edge of a facade element, a method for assembling plate-shaped facade elements and a facade for a building with at least partially integrated, plate-shaped facade elements.

The WO02 / 084038 describes a fastening system for fastening panel-shaped facade elements according to the preamble of claim 1.

The DE2539318 describes a fastening system in which trim parts are inserted directly into a slide that is mounted on a holding element.

The U.S. 3,838,546 describes a fastening system in which a locking element is located between two trim parts, the locking element being received by mutually facing grooves in the trim parts.

The EP 0 428 487 discloses a mounting device for fastening facade panels with sliding brackets inserted in support brackets, each of which engages with an upper and a lower flange in corresponding grooves in the end faces of facade panels.

Disadvantages of this design are the complex preparation of the facade elements with the necessary creation of frontal grooves, and overall complex handling. A facade panel can be replaced at a later date, but a facade panel still has to be provided with a cutout. This is ruled out with high-quality functional facade elements.

The DE 10 2010 046 376 A1 discloses a fastening system with an insert profile rail with an upwardly directed support receptacle with a short holding web and a downwardly directed holding receptacle with a long holding web.

This system is quite easy to handle, but the visible elements have to be anodized in a complex process, which makes the system more expensive. In addition, it is not possible to achieve a uniform facade appearance, as the connected upper and lower retaining bars are much wider than the lateral module spacings, so that unequal horizontal and vertical spacings result, which can be annoying under certain circumstances. In particular, in the case of large display areas, which can also be interconnected from a number of several display panels, the facade elements should have a spacing that is as small and uniform as possible on all sides.

In contrast, the invention is based on the object of creating a cost-effective and easy-to-use fastening system with which a homogeneous facade image can be built up.

A further object of the invention is to provide a method for assembling panel-shaped facade elements and a facade for a building with at least partially integrated, panel-shaped facade elements, with which a homogeneous facade image can be built up in a cost-effective manner.

The Figure 1 shows a side view of an embodiment of a fastening system 100 according to the invention.

For the fastening of facade elements 130, a plurality of vertically arranged base supports 120 are generally attached to the outer surfaces of a building 110.

A horizontally arranged mounting profile 140 is fastened to a base support 120. The mounting profile 140 has an essentially vertically aligned mounting section 150 in the installed state, which extends along the base support 120 and is fastened to the latter by being screwed onto the latter. In particular, it can be provided that the assembly section 150 is clamped to the base support 120 with a correspondingly shaped clamping iron 151 and a screw 152. The mounting portion 150 can, as in FIG Figure 1 shown, be bar-shaped or plate-shaped.

The Figure 2 shows a side view of an embodiment of the mounting profile 140, which has the fastening section 150 and a cantilever profile 160. The fastening section 150 is followed by the cantilever profile 160, which extends in particular transversely to it and, for example, protrudes essentially perpendicularly from the vertical fastening section 150. The cantilever profile 160 preferably extends essentially horizontally in the installed state. The cantilever profile 160 is connected at a first end to the mounting section 150 and has a second end, located opposite the first end and configured as a free end, so that an intermediate section 170 is located between the first and the second end, which is located in a distancing direction D away from the mounting portion 150 or the first end.

The free end of the cantilever profile 160 can be shaped as a holding section 180 in such a way that it has a crank 181 in the further course and in particular from the first end, following the intermediate section. A cranking, also cranking or cranked construction designates a short projection on a component, that is, a change in direction of a course axis.

The intermediate section 170 is shaped and dimensioned in accordance with the holding elements 200 provided for arrangement thereon such that it provides a support surface 171 on a first side S1 of the mounting profile 140. A holding element 200 located on the first side or above the cantilever profile (160) or above the intermediate section 170 is located on the support surface 171, the support surface 171 supporting and carrying the holding element 200. The rear side of the holding element 200, which is directed opposite to the distancing direction D and faces the fastening section 150, rests against a contact device or stop lip 173 ( Figure 2 ). The contact device can be formed by a surface section which is directed away from the fastening section 150.

The contact device or stop lip 173 is formed or arranged on a stop web 172 which extends transversely to the intermediate section 170 or the cantilever profile 160 and which is connected to the intermediate section 170 or the cantilever profile 160. The contact device or stop lip 173 can in particular be designed or arranged horizontally on a stop web 172 attached vertically to the cantilever profile 160 ( Figure 2 ). The stop web 172 extends on the first side of the mounting profile 140. The coordinated dimensions or depths (ie lengths in the distancing direction D) of the holding element 200 and the depth of the contact device or stop lip as well as the positioning of the stop web 172 on the cantilever profile ensure precise alignment of the holding element 200 is achieved relative to the holding section 180 of the mounting profile 140, in particular in the distancing direction D.

In particular, it can be provided that the fastening section 150, the cantilever profile 160 and the stop web 172 are produced as one piece or in one piece is.

In particular, an embodiment of the stop web 172 can also be provided in which this is formed on the first side as high as the holding element, so that the stop lip 173 engages around the profile of the holding element 200 at the top on the outer edge of the holding element 200 facing the first side S1 in a hook shape and secure against moving away from the cantilever on the first side. ( Figure 3 )

The Figure 4 shows in a side view how the free end of the cantilever profile 160 or the holding section 180 can be inserted at least partially into the groove 210 of a holding element 200 arranged below the cantilever profile 160 or on a second side S2 located opposite the first side S1 of the mounting profile 140 or that the groove 210 of a holding element 200 arranged below the cantilever profile 160 at least partially engages around the holding section 180. The groove 210 can in particular be designed as a groove that is open towards the first side of the mounting profile 140. The holding section 180 and the groove 210 are dimensioned such that the top of the holding element 200 facing the first side S1 on the underside of the cantilevered profile 160 facing the second side S2 and the inside of the groove 210 on the outside or the outside surface of the holding section 180 and the The rear side of the holding element 200 directed opposite to the distancing direction D rests at least partially against a stop web or stop profile 174 which is attached below the cantilever profile 160, is vertical or transversely to the intermediate section 170.

In particular, it can be provided that the fastening section 150, the cantilever profile 160, the stop web 172 and the stop web or the stop profile 174 are manufactured as one piece or in one piece.

The Figure 5 shows that the cross section of the holding section 180 adjoining the intermediate section has a guide 183 open towards the first side of the mounting profile 140 or towards the top for receiving an end section of a bolt 240. The cross section of the guide 183 and the cross section of the end section of the bolt 240 are matched to one another in such a way that the bolt 240 is in the guide 183 horizontally or in or along the distancing direction D, that is to say in the plan view of the Figure 5 in the depth or to the second side of the mounting profile 140, in the installed position horizontally in the facade plane to the left and right, has little or no play in its distance from the building in or along the spacing direction D.

The guide 183 can in particular be designed as a groove that is open towards the first side of the mounting profile 140.

The outside of the holding section 180 opposite the guide 183 has a rounded outer profile or rounded edges. Thus, a holding element 200 that is initially attached at an angle can still be rotated and aligned with the holding section 180 engaging in the groove 210 ( Figure 6a ).

The outer edge of the holding section 180 has a lower level in relation to the extent of the mounting section 150 and in relation to the installation state with regard to the direction of gravity, i.e. a different level in the direction from the first to the second side than the upper side of the cantilever profile 160 or on the first side. a level difference (dN) in order to enable a holding element 200 arranged above the cantilever profile to be pivoted in without problems. Furthermore, the holding section 180 can have a slight incline 190 in the area of the crank in order to be able to lift a pivoting holding element 200 easily and efficiently to the level of the support surface 171 of the cantilever profile 160 in order to then mount it on the support surface 171 ( Figure 6b ).

The Figure 7 shows a side view of a vertically arranged facade element 130 with two holding elements 200 attached to vertically opposite edges of a facade element 130, for example by gluing, screwing, riveting, etc. The holding profiles 200 include the facade element 130 on the edge and partially on the front.

In principle, however, other embodiments of a holding element are also possible, in which a facade element is held only on the edge without being surrounded on the front side or is only held on the rear side.

The Figure 8a shows an embodiment of a holding element 200 in profile. As a rule, extruded aluminum profiles are used to produce such profiles. Extrusion is a particularly suitable forming process for aluminum for the production of irregularly shaped profiles, i.e. elongated components with a cross section that is the same over the length, in which a compact is pressed through a die.

The holding element 200 produced in this way has a cross section with an in particular essentially rectangular basic shape with thin-walled webs or web sections 202, 203, 204, 215, 221, 222, 223 and a channel 230 or a cavity partially open to the outer contour of the holding element 200 230. A groove 210 which is open towards the outer contour of the holding element is also formed by correspondingly vertically arranged webs. The holding element 200 with the web sections 202, 203, 204, 215, 221, 222, 223 can be produced as one or in one piece. In the state of the retaining element 200 arranged on the cantilever profile 160, the groove 210 is open to the open side of the open guide 183 ( Figure 1 ).

Façade elements are usually thin cuboid or plate-shaped objects with a front side that will later form a façade in the installed position in combination with other elements, a rear side facing a building in the installed position and circumferential side surfaces or edges that bend at right angles and connect the front and rear sides .

The facade element extends in the room in one plane, whereby in the installed position the entirety of all installed facade elements form a facade plane, whereby from a design point of view not all facade elements have to actually lie in one plane. In Figure 8a the vertical course of this facade plane FE is indicated in the middle of the facade element 130. In particular, it can be provided that, in the case of a row of facade elements 130 arranged next to one another, the facade plane results from the longitudinal extensions of the row of facade elements 130 arranged one against the other.

To fasten facade elements, the holding element 200 has a fastening section 220 for fastening a facade element 130 to the Holding element 200 and a functional section 201 for fastening the holding element to the outer surface of a building.

In the illustrated embodiment, the fastening section 220 has a support web 211, an edge web 222 and a facade web 223, which form an enclosure that engages around a rear side, an edge surface and a front side of a facade element 130 when the end portion of a facade element 130 is received by the enclosure is. The support web 211, the edge web 222 and the facade web 223 together form an essentially U-shaped border, which opens transversely to the spacing direction D when the retaining element 200 is installed.

In the case of a holding element 200 located on the first side S1 of the mounting profile 140 in the assembled state, the U-shaped enclosure opens in a direction opposite to the direction of gravity, so that the enclosure absorbs the weight of the facade element received. In the case of a retaining element 200 located on the second side S2 of the mounting profile 140 in the assembled state, the U-shaped enclosure opens in the direction of gravity, so that the enclosure receives an upper edge section of the facade element in relation to the direction of gravity.

A facade element 130 is inserted into the enclosure formed by the webs or a holding element with this enclosure is pushed onto the edge of a facade element and e.g. glued.

At least one holding element 200 is mounted at least on the opposing edges of a facade element 130, which are located transversely to the spacing direction D or vertically spaced apart, or a correspondingly long profile is used as a profile frame surrounding the facade element 130 (not shown here).

In the functional section 201 of a holding element 200, in a remote from the facade plane FE, parallel to the facade plane FE and set back towards the distancing direction D or in the installation position towards the building A groove 210 which runs essentially parallel to the rear side of a facade element 130 and is open towards the edge region of a facade element is arranged in another plane. The groove 210 is formed from two side webs running parallel to the first side or extending essentially vertically, and a horizontal web that attaches to one end of the side webs and connects them.

In the exemplary embodiment, the groove 210 is formed by a vertically running support web 211, a horizontal base web 215 and a vertical channel web 203.

The width and depth of the groove 210 are dimensioned such that a holding section 180 of a mounting profile 140 can at least partially be introduced. The holding section 180 is essentially U-shaped and can be inserted with its closed part into the groove 210, so that the opposite outer surfaces of the legs of the holding section 180 are located between facing surfaces of the groove 210, in particular on these can concern.

The functional section 201 also has the channel 230, which is formed from two side webs 203, a support web 202 and an interrupted cover web 204 and contributes to stiffening while at the same time saving material. In the assembled state, the channel 230 extends transversely to the distancing direction and along the extent of the border of the fastening section 220. The channel 230 can be open in sections or designed to be closed in the circumferential direction. Using angles inserted in such a channel 230, e.g. Connect two holding elements at a corner and it can be used to produce circumferential profile frames (not shown).

The Figure 8b shows the side view of a further embodiment of a holding element 200 with two smaller channels 230; wherein a channel 230 adjoins the fastening section 220 and thus one outer wall of which is the support web 221, and the groove 210 is arranged centrally between the channels 230.

The Figure 8c shows the side view of a further embodiment of a Holding element 200 with again only one channel 230, the channel 230 being arranged adjacent to the fastening section 220 and the groove 210 in the end of the holding element 200 opposite the fastening section

The Figure 8d shows a further embodiment of a holding element 200. For this purpose, a holding profile 265, which is already used for framing solar modules, is supplemented with a clip 260, so that conventionally framed solar modules can be modified for use with the holding system according to the invention.

For this purpose, the clip 260 has in its profile a cover web 261 and an angled cantilever web 262 arranged on the cover web 261.

For assembly, the cantilever web 262 is inserted through the opening 231 into the channel 230 so that the cover web 204, which partially closes the channel 230, is covered by the cantilever web 262 ( Figure 8e ).

The clip 260 is moved further until the cantilever bar hits the inner wall of the channel 230 ( Fig. 8f ).

In this position, the locking web 263 snaps into the opening 231 of the channel 230, whereby the clip 260 is positively connected to the retaining profile 200 ( Fig. 8g ). In addition, to further secure a built-in clip, a locking element can also be inserted axially into the channel 230, which locks the cantilever element 262 in its position resting against the inner wall of the channel and thus prevents the clip from being released from the retaining element (not shown).

A composite of retaining profile 265 and clip 260 produced in this way together forms a retaining element 200 with a fastening section 220 for receiving a facade element 130 and a functional section 201 for fastening to buildings. The groove 210 required for this is formed from a side surface of the retaining profile 265 and the groove web 215 as well as the side web 203 of the offset and angled profile of the clip 260 ( Figure 8h ).

The Figure 9a shows a further embodiment of a holding element 200 with a modified fastening section 220 which does not have a front facade web has, but supports a facade element 130 only on a rear side with a support web 221 and laterally on the edge with an edge web 222. A facade assembled with retaining elements designed in this way would have a very uniform appearance, since only the facade elements 130 and the edge webs 222 would be visible on the facade.

Figure 9b FIG. 11 shows a further embodiment of a holding element 200 with a modified fastening section 220 which, based on FIG Fig. 8 b also no longer has an edge web, but a facade element is only connected to a support web 221 on a rear side. A facade assembled with holding elements designed in this way would have a very compact and uniform appearance, since no holding elements would be visible and the facade elements could practically be installed end to end or with only minimal expansion joints. In particular, the facade elements could be mounted with their edges protruding over the holding elements (not shown here).

Figure 9c FIG. 4 shows a further embodiment of a holding element 200 with a modified fastening section 220, which, based on FIG Figure 8c has an enlarged edge web 221 and thus provides a larger area for fastening a facade element and so larger or heavier elements can also be securely fastened.

The height of the cantilever profile on which an upper facade element is placed with a holding element and the lowering of the holding section by the cranking of the cantilever profile towards the underside of the cantilever profile cause a distance between vertically adjacent facade elements. In order to keep this distance as a visible gap small, a holding element can be provided with an offset so that the edge of a facade element or its surround protrudes over the support surface of the holding element and thus bridges the distance or reduces a gap ( Figure 10a ).

The Figure 10b shows the profile view of two holding elements in comparison, on the right in the picture with an offset V, in that the support web 202 is set back with respect to the outer contour of the holding element or the edge web 222, so that the edge web 222 protrudes with its outer edge above the level of the support web 202.

The Figure 10c shows the profile view of two holding elements in comparison, on the right in the picture with an offset V, in that the groove web 215 is set back in relation to the outer contour of the holding element or the edge web 222 in the direction of extent of the facade element 130, so that the edge web 222 is lower with its outer edge than a Holding element without such an offset.

The Figures 11a to 11d shows an example of the assembly of a facade element 130.

For this purpose, two mounting profiles 140 are attached to a base support 120 running horizontally at a corresponding distance from one another. A facade element 130 with two holding elements 200 fastened to vertically opposite edges of the facade element 130 is inserted between these assembly profiles 140.

In a first step ( Figure 11b ) the facade element 130 is pivoted with respect to the facade plane (FE) and thus moved slightly obliquely to an upper mounting profile 140, the holding element 200 with the groove 210 being placed on the holding section 180 or placed on the holding section 180 with the groove side surface 212 on the facade element.

In a further step ( Figure 11c ) the facade element 130 is lifted slightly upwards so that the holding section 180 is at least partially inserted into the groove 210 or the holding element 200 easily engages on the holding section 180.

Then the facade element 130 is pivoted back into the facade plane FE until it rests with the rear side of the lower retaining element 200 facing the assembly profile on the vertical stop web 172 or the horizontal stop lip 173 of the lower assembly profile 140 and is vertically aligned ( Figure 11d ). The lower holding element 200 is supported with its underside on the support surface 171) of the lower mounting profile 140.

Finally, a bolt 240 is inserted into the guide 183 of the holding section 180 of the lower mounting profile 140 and pushed horizontally in the facade plane FE into the groove 210 of the holding element 200 ( Figure 11e ).

As shown in FIG. 11i, the latch 240 has an L-shaped cross section with a long leg 241 and a short leg 242, the L being upside down. The long leg 241 is held by the guide 183 of the holding element 200 and points upwards. The leg 241 is so long that it extends from the guide 183 of the holding section 160 to the groove base 215 of the groove 210. The short end (242 points away from the facade element 130 in the direction of the building and is so long that it reaches as far as the building-side inner side 212 of the groove (210), so that the holding element 200 is clamped between the bolt 240 and a stop surface 173 of the mounting profile 140 is or is mounted opposite the structure, since it is now fixed vertically between the cantilever arms of the two mounting profiles 140 and the holding section 180, holding element 200 and bolt 240 cannot be released due to the positive locking.

The bolt 240 can be moved in the guide 183 either to the middle or to the opposite side of the facade element 130 and further bolts 240 can be inserted. In an embodiment not shown here, the bolt 240 in the guide 183 can be secured against unintentional displacement, for example with a worm screw.

Another embodiment of a fastening system is shown in FIGS Figures 12a to 12e .

The Figure 12a shows a modified mounting profile 140 in a side view, in which the holding section 180 has a hook-shaped crank 181. A horizontally running spacer web 182 is arranged in the area of the crank. At approximately the same material thickness as the wall of the holding element 200 from the cranked portion 181, there is a vertical stop web 172 which runs parallel to the cranked, vertical holding portion 180 and is arranged above the cantilevered profile 160.

According to the profile of the mounting element, a holding element 200 is used in which the channel 230 is arranged centrally between the fastening section 220 and the groove 210 and the groove 210 is arranged directly on the end of the holding element 200 opposite the fastening section 220 ( Figure 12b ).

In a first step ( Figure 12c ) the facade element 130 is pivoted with respect to the facade plane FE and thus moved slightly obliquely to a lower mounting profile 140 of two correspondingly spaced mounting profiles, the lower holding element 200 with the groove 210 on the hook-shaped holding section 180 of the cantilever 160 or with the groove 210 the holding section 180 is placed.

The facade element 130 is then pivoted into the facade plane FE, so that the outer side wall of the groove 210 or the lower holding element 200 is held between the free end of the hook-shaped holding section 180 and the stop web 172 of the lower mounting profile 140, the lower holding element 200 is supported downwards on the support surface 171 of the cantilever profile 160. Fig. 12 d) , and the upper holding element with its rear side facing the upper mounting profile 140 rests against a vertical stop profile 174 projecting downward from the upper mounting profile 140 Figure 12e ).

In a next step ( Fig. 12 e) a further facade element 130 is set in the facade plane FE below the first facade element 130, in such a way that the rear side of the upper retaining element 200 of the additional facade element 130 facing the mounting profile 140 is located on a lower stop web 172 of the now in the middle between the two facade elements 130 Mounting profile 140 rests and the grooves 210 of the two now opposing holding elements 200 face one another and are aligned. The upwardly open groove 210 of the lower holding element takes on the task of receiving and guiding the bolt 240).

Finally ( Figure 12f ) an L-shaped bolt 240 is inserted into the vertically aligned grooves 210 with facing openings of the two opposing retaining elements 200, the long leg 241 extending from the groove base 215 of the lower groove 210 to the groove base 215 of the upper groove 210 and the inside of the long leg 241 rests on the spacer web 182 of the holding section 180, the outside of the L-shaped bolt 240 on the inside 211 of the grooves 210 of the two on the inside 211 of the facade element opposite holding elements 200 rests. The outside of the short leg 242 rests against the groove base 215 of the lower holding element 200 and points away from the facade element 130 in the direction of the structure. With its end face it presses the lower holding element 200 against a vertically running stop profile 174) arranged below the cantilever profile 160, in that the end face of the short leg 242 presses on the building-side inner side 212 of the groove 210 of the lower holding element 200.

The cross-section of the L-shaped bar 240 can also be varied in such a way that the width of the long limb 241 and short limb 242 are increased so that the insides of the long and short limbs 241, 242 lie directly against the crank 181 of the holding section 180 . In this case, the holding section 180 does not have a spacer web 182 ( Fig. 13 ). The inserted bolt 240 thus fixes an upper holding element 200 in the normal to the facade plane FE and a lower holding element in the vertical. Since both corresponding facade elements are each connected on the opposite side with also locked retaining elements, the facade elements are mounted and locked in this way.

A modified latch or bracket is suggested to complete a last row of facade elements.

The Fig. 14 shows the profile of a bolt 240, in which a hook-shaped profile 243 is arranged on the long leg 241, which engages from above behind the cranked area 181 of the holding section 180 of the corresponding mounting profile 140 and locks in a form-fitting manner.

Alternatively, the use of a clamp 250 is proposed, which is placed on the long leg 241 of the bolt 240 and grips from above behind the cranked area 181 of the holding section 180 of the corresponding mounting profile 140 and locks in a form-fitting manner ( Fig. 15 )

The Fig 16 FIG. 4 shows an example of a fastening device, the holding elements 200 shown being made from conventional solar module frames and clips 260 are joined together. Again, several horizontally arranged rows of facade elements are provided here, which are arranged vertically one above the other. In the side view, however, only two adjacent rows are shown with a mounting profile 140 arranged between these rows and extending over the entire width of a building.

The crank 181 of the holding section 180 of a first mounting profile 140 is executed here vertically above the cantilever profile 160 and on the outside forms an angular contour. A first facade element 130 with its vertically lower edge and the holding element 200 arranged there is placed obliquely on this crank 181 and pivoted into the facade plane until the groove 210 sits snugly on the crank 181 and is positively fixed. After the opposite edge of the element has been pivoted into the facade plane, a bolt 240 is used to fix the facade element 130 laterally, i.e. parallel to the facade plane, in the vertically upwardly open groove 210 and the vertically downwardly open guide 183 of the crank 181 of a further mounting profile 140 inserted. The bolt fits largely without play in the guide 183 and has a corresponding height to fix a facade element in the vertical. In order to also fill the groove 210 of the holding element 200 of the facade element to be fixed and thus fix it at right angles to the facade plane without play, spacer lips 244 are provided laterally outside the guide 183, each extending to the lateral groove inner surfaces.

The Figure 17 Figure 3 shows another example of a fastening device. The mounting profile 140 has in its fastening section 180 a hook-shaped crank with a hook pointing vertically upwards.

A first facade element 130 with its vertically lower edge and the holding element 200 arranged there is placed obliquely on this hook or crank 181 and pivoted into the facade plane until the groove 210 rests on the crank 181. For better mounting, the holding section has a spacer web 182, so that the width of the groove 210 is bridged and the holding element 200 is mounted largely free of play.

After the opposite edge of the element has been pivoted into the facade plane, a bolt 240 is inserted laterally into the vertically upwardly open groove 210 of the upper retaining element 200 to fix the facade element 130 there, i.e. parallel to the facade plane. In this exemplary embodiment, the bolt is cranked so that it is pivoted outside the groove and rests vertically from below on the fastening section 180 of the mounting profile and engages behind the fastening section 180 on the building side and so that the facade element 130 is fixed vertically and in the facade plane.

The bolt can also be fixed by yourself, e.g. via a steel pin 245, which is inserted via vertical joints.

The Fig. 18 schematically shows a facade of a building 110 with vertically running base beams 120, horizontally arranged mounting profiles 140 and a facade element 130 inserted between two mounting profiles 140, which is connected to a bolt 240 inserted in a guide 183 or placed on a lower mounting profile 140 by horizontally moving the bolt 240 is locked in the groove 210 of the lower holding element 200 of the facade element 130. The bar or bars preferably have a total length of approximately 1/20 to 1/2 the width of a facade element 130, particularly preferably 1/4. One or more bars can be used.

An inserted latch is moved with a thin tool from the front or the side to the desired position. There it can, if necessary, be secured against further, unintentional displacement, e.g. with a worm screw. Possibly. further bolts are inserted and pushed in accordingly.

A possibly desired unlocking can be achieved by using a flat tool to push the bolt out of the engagement area of the holding element of a facade element horizontally to the left or right in the facade plane.

The mounting elements as shown can also be mounted rotated by 180 ° with a facade structure that is then appropriately adapted.
