EP3767053B1 - Device for applying plate-shaped facade elements to a subsurface fixed to a building side or a substructure fixed to a building side, facade with plate-shaped facade elements - Google Patents

Description

The invention relates to a device for attaching panel-shaped facade elements to an on-site subsurface or to a substructure which is fastened to an on-site subsurface. The plate-shaped facade elements can in particular be plates made of ceramic, natural stone or artificial stone. Furthermore, facade elements made from glass panes can be attached to an on-site subsurface or to a substructure fastened to an on-site subsurface with the aid of the proposed device. The invention also relates to a facade with panel-shaped facade elements.

Devices of the type mentioned above are used in particular for the formation of curtain-type, rear-ventilated facades (VHF). In the case of a curtain-type, rear-ventilated facade, panel-shaped facade elements are hung in front of a wall construction with the formation of an air layer serving for rear ventilation, which is usually insulated on the outside for structural reasons. Since no panel-shaped facade elements can be attached to the outside insulation or insulation layer, a substructure is to be provided which is in the plane of the insulation layer and to which the panel-shaped facade elements can be attached. They are attached with the help of devices which, after they have been attached to the substructure, enable the panel-shaped facade elements to be inserted, pushed in or hooked in, and preferably in such a way that the device itself is not visible. For this purpose, mounts are known from the prior art which have a mandrel that can be brought into engagement with a recess of a facade element or a web section that can be brought into engagement with a groove of a facade element.

From the EP 0 428 487 A1 For example, a mounting device for a curtain cladding made of panel-shaped facade elements emerges, which enables both a mandrel holder and a groove holder for plate-shaped facade elements. For this purpose, the assembly device comprises at least one support bracket which is held vertically displaceably in a vertically running support profile which is indirectly attached to a building structure via a spacer which is likewise vertically running. The vertically displaceable support bracket has a horizontally running groove into which a slide holder of the assembly device can be inserted horizontally displaceably. Depending on whether a mandrel holder or a groove holder is to be implemented, the sliding holder has a mandrel that can be brought into engagement with a lateral cutout of a facade element or at least one flange that can be brought into engagement with a groove on the face of a facade element. The vertical displaceability of the support bracket and the horizontal displaceability of the sliding bracket enable the panel-shaped facade elements to be adjusted in the facade plane. In this way, any laying tolerances can be compensated for while the facade elements are being installed. In addition, an adjustment perpendicular to the facade level can be achieved using the spacer.

From the EP 0 272 658 A2 a substructure for facade cladding of vertical walls is known, in which the cladding elements are held in point form by fastening means. The fastening means comprise an intermediate part with a guide flange, which is received vertically displaceably in a guide channel of a support profile. The guide flange and the guide channel are provided with interlocking serrated strips which are shown in Standing engagement prevent a vertical displacement of the intermediate part with respect to the mounting rail.

Starting from the prior art mentioned above, the present invention is based on the object of further simplifying the attachment and adjustment of panel-shaped facade elements.

To achieve the object, the device with the features of claim 1 and the facade with the features of claim 12 are proposed. Advantageous further developments of the invention can be found in the respective subclaims.

The proposed device is used to attach panel-shaped facade elements to a subsurface provided by the customer or to a substructure fastened to a subsurface provided by the customer. The device comprises a supporting profile and a sliding holder, the sliding holder having a plate-shaped section that can be inserted into a guide of the supporting profile, so that the sliding holder can be displaced in a first direction x with respect to the supporting profile. According to the invention, the sliding holder has a plate-shaped section which can be inserted into a guide of the supporting profile and which has a profile on the rear consisting of webs and / or grooves running parallel to the first direction, which can be brought into engagement with an oppositely designed profile of the supporting profile, so that the sliding holder can be offset in a second direction perpendicular to the first direction. According to the invention, the plate-shaped section of the slide holder has a profile on the rear side, which consists of several webs and / or grooves running parallel to the first direction x and can be brought into engagement with an oppositely designed profile of the support profile, so that the slide holder is perpendicular to the first direction x extending second direction y is displaceable.

The sliding holder of the proposed device can thus be shifted or offset relative to the support profile in two mutually perpendicular directions. This means that only the sliding holder has to be shifted or displaced in order to carry out an adjustment, in particular a fine adjustment, which leads to the desired joint pattern of the panel-shaped facade elements to be attached. Construction and / or assembly tolerances can thus be compensated for in a simple manner. Neither the support profile nor any existing substructure needs to be moved again after it has been attached to the subsurface.

According to the invention, the support profile of the proposed device is attached to the on-site subsurface or to a substructure attached to the on-site subsurface in such a way that the guide of the support profile is aligned horizontally and, when the slide holder is inserted, enables the slide holder to be displaced relative to the support profile in the horizontal direction (direction x) . The oppositely designed profiles of the sliding holder and the supporting profile enable in this case an offset of the sliding holder with respect to the supporting profile in the vertical direction (direction y). The two directions x and y are preferably in a plane that runs parallel to the subsurface on site.

Using the profiling provided according to the invention on the slide holder and on the support profile, in particular the height of the slide holder can be adjusted. Since the profiles in the direction x, that is, form horizontally extending webs and / or grooves, they also allow a displacement of the sliding holder with respect to the support profile in the direction x or in the horizontal direction.

According to a preferred embodiment of the invention, the profiling of the sliding holder and / or the support profile forms a plurality of teeth in cross section. With the help of the teeth, which engage in oppositely designed interstices of the respective joining partner, a form fit can be achieved which prevents a relative movement of the sliding holder with respect to the support profile in the y-direction, but allows it in the x-direction. This means that the profiling enables a separate adjustment according to directions, which simplifies the adjustment. First the position of the slide holder is specified in one direction, then in the other direction. Preferably, the height of the slide holder is first determined and the slide holder is fixed in this height position by the form fit. The slide holder can then - if necessary - be moved horizontally.

Furthermore, the teeth are preferably shaped asymmetrically. The asymmetrical shape helps to improve the form fit between the slide holder and the support profile. In particular, the teeth can have tooth flanks that are inclined to different degrees. With the help of a particularly steep or perpendicular tooth flank, an optimized support surface can be created. In this case, the force is introduced essentially perpendicular to the support surface. In contrast, the other tooth flank is designed to run obliquely, so that the tooth has a large width at its base, since the forces introduced into the tooth add up towards the base, increased mechanical stability of the toothing can be achieved in this way.

To increase the stability, it is also proposed that the slide holder and the support profile are made of a metallic material, for example steel, in particular galvanized steel, stainless steel or aluminum. Manufacture from a high-strength composite material would also be conceivable, provided that it meets the relevant fire protection requirements.

According to the invention, the device comprises a terminal strip which can be inserted at least in sections into the guide of the support profile, so that the slide holder is held in the guide in a force-fitting and form-fitting manner. With the help of the clamping strip, a clamping force can be exerted on the sliding holder, which presses the sliding holder against the support profile, specifically in such a way that the opposing profiles optimally mesh with one another. The sliding holder is accordingly held in the guide of the support profile on the one hand by a form fit with the support profile and on the other hand by a force fit with the clamping profile. The terminal strip is accordingly arranged on the side of the slide holder facing away from the profiling.

The terminal strip or the section of the terminal strip inserted into the guide of the support profile fills a guide play that is necessary to move the slide holder in the y direction. The guide play corresponds at least to the depth of the profiling of the sliding holder in order to be able to release the engagement with the profiling of the support profile if necessary. The terminal strip accordingly has at least one section, the width of which essentially corresponds to the guide play in the guide. This ensures that, in the event of an unfavorable load on the slide holder, the form fit between the slide holder and the support profile is not unintentionally canceled and the slide holder experiences a change in position.

Preferably, the terminal strip can be connected to the support profile, preferably to a profile section of the support profile that delimits the guide, in a non-positive and / or form-fitting manner. The force fit and / or form fit with the support profile prevents the terminal strip from slipping out of the guide. In this way, the slide holder also remains securely fixed in its position. The terminal strip can be made from a metallic material or from plastic, for example from polytetrafluoroethylene (PTFE). PTFE has a very low coefficient of friction, so that the subsequent insertion, in particular pushing in, of the terminal strip is simplified.

Furthermore, the terminal strip is preferably designed to be essentially U-shaped in cross section, so that the terminal strip, after being inserted, in particular pushed into the guide of the support profile, engages around the profile section of the support profile that delimits the guide. The dimensioning of the U-shaped terminal strip can be selected in such a way that the two parallel legs of the terminal strip each rest against the profile section of the support profile under a bias. In this way, a frictional connection can be achieved. As an alternative or in addition, it is proposed that the terminal strip form at least one tongue which engages in a groove in the profile section of the support profile or vice versa. This means that the at least one tongue is formed on the profile section of the support profile and the terminal strip has at least one groove for receiving the tongue. In this way, a form fit is achieved.

In addition, it is proposed that the support profile forms a further guide for the slide holder running parallel to the guide, so that when the slide holder is inserted, the support profile engages around the plate-shaped section of the slide holder on two opposite sides. The further guidance stabilizes the slide holder, since it can be supported on two opposite sides of the support profile.

To hold the plate-shaped facade elements, the sliding holder can form a holding section or have a holding part. The slide holder can accordingly be made in one or more parts. The one-piece design makes assembly easier because fewer parts need to be assembled. The multi-part design extends the adjustment options by changing the position of the parts in relation to one another.

The holding section of the sliding holder is preferably T-shaped in cross-section and can be brought into engagement with grooves on the face of the panel-shaped facade elements. This means that a groove holder can be implemented with the aid of the holding section.

If, instead of a holding section, the sliding holder has a holding part, that is to say a separate part, for holding the panel-shaped facade elements, this is preferably screwed into a threaded hole in the sliding holder. The longitudinal axis A of the threaded hole extends in a third direction z running perpendicular to the first direction x and perpendicular to the second direction y.

An adjustment in the third direction or in the z-direction can thus be carried out via the screw-in depth of the holding part, which is the direction running perpendicular to the subsurface on site. In this way, the position of the panel-shaped facade elements can be changed with the help of the sliding holder alone in such a way that a flat facade surface is created.

The holding part preferably has a recess into which a mandrel is inserted, preferably screwed or pressed. A mandrel holder can be realized in this way. The formation of the mandrel as a separate part enables the use of different mandrels, so that a mandrel can be selected that is optimally adapted to the panel-shaped facade elements.

According to a further preferred embodiment, the holding part has at least one receiving section for receiving a facade element, the receiving section preferably being L-shaped or U-shaped and / or engaging around the edge of the facade element. The facade element can also be held in a form-fitting manner via the at least one receiving section. For example, a rear leg of the receiving section can engage in an edge-side groove of the facade element. In this case, the holding part is not visible. The leg can, however, also jump in front of the facade element and encompass it at the edge so that the retaining element is visible and can be used to design the facade. In order to hold two facade elements lying one above the other in a form-fitting manner, the holding part can have two U-shaped receiving sections which, lying back to back, lead to an H-shaped cross section. However, a spacer located back for forming a shadow gap can also be arranged between the two receiving sections.

The sliding holder is advantageously designed with mirror symmetry in cross section and the plate-shaped section has two at the rear opposite sides each have a profile, so that the orientation of the slide holder when it is inserted into the support profile is irrelevant. In this way, the assembly can be further simplified.

To solve the aforementioned problem, a facade with rear-ventilated panel-shaped facade elements is also proposed, which are attached to an on-site substrate or to a substructure attached to an on-site substrate with the aid of a device according to the invention. The use of a device according to the invention for attaching the facade elements enables adjustment, in particular fine adjustment, to compensate for construction and / or assembly tolerances.

According to the invention, the support profile of the device is oriented in such a way that the first direction x runs horizontally, the second direction y runs vertically and the third direction z runs perpendicular to the plane of the subsurface on site. The joint pattern can be corrected by adjusting the device in the x and y directions. An adjustment in the direction z creates a flat facade.

The one in the Fig. 1 The device shown comprises a support profile 2 and a sliding holder 3, which is inserted into the support profile 2 in sections. For this purpose, the sliding holder 3 has a plate-shaped section 5 which engages on the one hand in an upper guide 4 and on the other hand in a lower guide 11 of the support profile 2. The plate-shaped section 5 has a profile 6 on the rear (see also Figures 5a, 5b and 5c ). In the Fig. 1 If the profiling 6 is in engagement with a profiling 7 of the support profile 2, which is configured in opposite fashion, the sliding holder 3 is thus held in the guide 4 of the support profile 2 in a form-fitting manner. In addition, a frictional connection is achieved between a terminal strip 9 inserted into the guide 4 and the sliding holder 3, so that the sliding holder 3 is fixed in position. The terminal strip 9 fills a guide play remaining between the sliding holder 3 and a profile section 10 of the supporting profile 2 that delimits the guide 4, so that the form fit between the sliding holder 3 and the supporting profile 2 is secured. This is because the terminal strip 9 is also connected to the support profile 2 in a non-positive and form-fitting manner via a tongue 18 which engages in a groove 19 of the profile section 10 of the support profile 2.

In the present case, the terminal strip 9 has an essentially U-shaped cross section, so that the terminal strip 9 engages around the profile section 10 of the support profile 2 that delimits the guide 4. On the two parallel legs 20, a flange 21 is formed at each end, which causes a stiffening of the terminal strip 9 (see Figures 6a and 6b ).

The support profile 2 is in the Figures 4a and 4b presented in isolation. The cross section of the Figure 4a clearly shows that the guide 11 is designed differently from the guide 4. In particular, the guide 11 lacks a "rear wall". Instead, a support wall 22 is provided, which is located in front of the actual guide 11. Like in the Fig. 9 shown, the sliding element 3 is first inserted into the guide 11 and pivoted around the support wall 22 in the support profile 2, so that then the sliding element 3 upwards into the Guide 4 can be inserted. The height of the sliding element 3 can be varied as desired, since the profile 6 can be brought into engagement with the profile 7 of the support profile 2 at any height. After the height position has been determined by moving the sliding holder 3 in a first direction y, the sliding holder 3 can be moved horizontally with respect to the support profile 2, that is, in a second direction x (see FIG Fig. 3 ) to make the required adjustment. For the final fixing of the position of the sliding holder 3, the terminal strip 9 is then inserted into the guide 4 or pushed in laterally.

In the device of the Fig. 1 the slide holder 3 has a separate holding part 13 which is screwed into a threaded hole 15 of the slide holder 3. The longitudinal axis A of the threaded hole 15 defines a third direction z, which extends perpendicular to the plane of an on-site subsurface (not shown).

The device of the Fig. 1 therefore allows adjustment in all three spatial directions, i.e. in the directions x, y and z. For this purpose, only the slide holder 3 has to be moved in whole or in part. The support profile 2 remains unchanged after its assembly. The same applies with regard to a possibly existing substructure (not shown), via which the support profile 2 of the device is indirectly attached to the subsurface provided by the customer.

To accommodate plate-shaped facade elements 1, the holding part 13 of the in the Fig. 1 The slide holder 3 shown has a recess 16 into which a mandrel 17 can be inserted. The mandrel 17 can be brought into engagement with a recess 23 of a plate-shaped facade element 1, as exemplified in FIG Fig. 10 shown. The mandrel 17 is held centrally in the recess 16 of the holding part 13, so that it can be brought into engagement with a further recess 16 of a further facade element 1. The holding part 13 therefore comes to rest in particular in a joint between two facade elements 1.

Another (second) preferred embodiment of a device according to the invention is that Fig. 2 refer to. The support profile 2 and the terminal strip 9 are designed in the same way as the support profile 2 and the terminal strip 9 of the embodiment described above. Only the slide holder 3 is modified. In the present case, the sliding holder 3 is made in one piece and has no holding part 13. Instead, the sliding holder 3 forms a holding section 12 which is T-shaped in cross section (see FIG Fig. 8 ) and can be brought into engagement with grooves 14 arranged at the end of two plate-shaped facade elements 1, as exemplified in FIG Fig. 11 shown. At the other end, the slide holder 3 also has a plate-shaped section 5, which is designed analogously to the plate-shaped section 5 of the slide holder 3 of the embodiment described above, so that the slide holder 3 can be "swiveled" into the support profile 2 and positioned in an analogous manner (see FIG Fig. 9 ). For this purpose, the plate-shaped section 5 of the sliding holder 3 has a profiling 6 on the rear side, which can be brought into engagement with a profiling 7 of the support profile 2 which is configured in opposite directions (see FIG Figures 7a and 7b ).

The rear profile 6 of the plate-shaped section 5 of the sliding holder 3 of a device according to the invention has several webs 6.1 and grooves 6.2 running parallel to the first direction x (see FIG Figure 5b and Figure 7b ). This means that even when the profiling 6 is in engagement with the profiling 7 of the support profile 2, a displacement of the sliding holder 3 in the direction x is possible. The position of the sliding holder 3 in the x direction is only achieved when the terminal strip 9 is inserted or pushed in.

As exemplified in the Fig. 5d shown forms the rear profiling 6 of the plate-shaped section 5 of the slide holder 3 of a device according to the invention in cross section teeth 8 which have tooth flanks 8.1, 8.2 which are inclined to different degrees. The tooth flank 8.1 is essentially perpendicular led to the plate-shaped section 5 of the slide holder 3, while the tooth flank 8.2 slopes down towards the base. The essentially vertically guided tooth flank 8.1 optimizes the form fit with the oppositely designed profiling 7 of the support profile 2, since the teeth 8 are optimally supported against one another. The inclined tooth flank 8.2 widens the base of the tooth 8 and thus leads to increased mechanical stability. With the aid of the device, particularly heavy panel-shaped facade elements 1, such as panels made of ceramic, natural stone or artificial stone, can be attached to an on-site substrate or to a substructure.

Another (third) preferred embodiment of a device according to the invention is that Fig. 12 refer to. The support profile 2, the sliding holder 3 and the terminal strip 9 are identical to the embodiment of Fig. 1 executed. In this respect, the description for Fig. 1 to get expelled. The device of the Fig. 12 furthermore comprises a holding part 13 which is screwed into a threaded bore 15 of the slide holder 3. The longitudinal axis A of the threaded hole 15 also defines a third direction z here, which extends perpendicular to the plane of a subsurface (not shown) on site. Analogous to the device of Fig. 1 therefore also enables the device of Fig. 12 an adjustment in all three spatial directions, i.e. in the directions x, y and z. The slide holder 3 is moved for adjustment in the spatial directions x and y. For adjustment in the spatial direction z, the screw-in depth of the holding part 13 in the threaded hole 15 is changed.

That in the Fig. 12 The holding part 13 shown has two receiving sections 24 which are each U-shaped so that they each encompass a facade element 1 of a corresponding width at the edge. In this way, a form fit is brought about, which holds the facade elements 1 securely. At the same time, a leg 25, which protrudes from the respective facade element 1, can be used to design the facade (see FIG Fig. 13 ).
