Definitions
- the present invention relates to a fastening device for facade elements, in particular for glass facades of buildings, which are to be fastened to a frame construction or to a shell construction of the building.
- the invention relates in particular to such fastening devices for facade elements, which are provided with a metal frame or supporting elements, which can be mounted as a kind of prefabricated product together with the plate-shaped facade elements, glass panes, metal sheets or the like on the buildings via fastening means corresponding to the production of the building facade .
- Such fastening devices are used in particular for the assembly of prefabricated glass facade parts.
- such fastening devices are also used for the assembly of other facade elements of buildings, in order to realize the respective facade elements to close off the weather side over a large area as an outer skin of the building on the shell or on a prefabricated frame construction of the building.
- the glass facades or other facade elements must be attached to the building in a sufficiently secure and stable manner.
- the fastening devices must have sufficiently high strength values in terms of flexural rigidity and stability, even with strong wind forces or the like, in order to meet the static specifications for such building constructions.
- fastening devices for facade elements represent direct cold bridges in the construction of the facades at the points of the frame parts, which are usually made of aluminum profiles. Even if highly insulated glass surfaces with, for example, triple glazing are used, it is the case that the fastening devices locally increase the heat transfer between the outside of the facade and an interior of the building due to the metal frame parts required for stability.
- fastening devices for facade elements have been proposed in the past, in which a metal frame or metal profile element was used as the basic element of the fastening device and which are provided with a substantially L-shaped holding element with reduced thermal conductivity, which Outside of the facade parts, such.
- glass surfaces as disclosed for example in EP 2438 248 B1.
- the object of the present invention to provide a fastening device for such facade elements, in particular glass facades of buildings, with which high-energy materials (e.g. aluminum) can be combined with low-energy or CO2-neutral materials in terms of climate protection (e.g. wood) can be replaced or supplemented and the static requirements with regard to the bending stiffness and strength of such facade attachments are still met.
- the fastening device according to the invention is intended to provide a fastening device that is optimized in terms of environmental aspects and sustainability, which allows cost-efficient production and simple assembly on the construction site. This object is achieved with a fastening device having the features of claim 1 and claim 15.
- a fastening device for facade elements with a metal frame with an essentially L-shaped holding element that overlaps the facade elements to the outside and is made of a material that reduces heat conduction and is detachably fastened to the metal frame using fastening means
- the metal frame is formed with at least one hollow chamber and comprises a facade holding section as well as a support section pointing inwards from the facade element from a facade outside essentially perpendicularly to the plane of the facade elements
- the fastening device being characterized in that on the support section of the metal frame, a beam module made of non-metallic material is attached by positive locking at at least two attachment points provided at a distance from one another, which extends over the entire length of the respective metal frame ns or metal frame part extends continuously and which is coupled to the metal frame on an inside of the facade element in such a way that it is statically effective in the installed state of the fastening device through the form fit to increase the bending stiffness and tors
- the metal frame according to the fastening device according to the invention is therefore no longer a pure metal frame, but has on the support section provided on the inside of the facade a beam module made of a second material, a non-metallic material such as wood, plastic or the like, which is used for the support function, Statics and stability of the fastening device and thus the facade as a whole is designed and constructed.
- the fastening device is thus provided with a non-metallic bar module on the inside of the facade elements, which is fastened to the support section of the metal frame by a form fit in such a way that it is itself effectively integrated into the structure for the statics.
- the beam module which can be a wooden beam, for example, is attached to the at least two attachment points of the metal frame by a simple positive fit.
- the attachment is such that the at least two attachment points are provided at a distance from each other, so that the rigidity and in particular the flexural strength of the frame part of the attachment device is significantly increased with the beam module in order to achieve a required total flexural strength of the facade attachment, which is required for facade elements of this type is prescribed to reach together with the metal part of the support section of the metal frame.
- the positive connection type takes into account the specific properties of the individual materials and at the same time leads to a statically effective combination effect, which means that the project requirements with regard to the bending and tensile strength of such facade attachments can be met.
- the different materials are specifically used or arranged within the construction.
- the resulting long-term usability leads to an extremely effective sustainability of the fastening device, since the structure can be dismantled into its individual parts, recycled or reused without great effort even at the end of the usage phase.
- a wide variety of aesthetic aspects with regard to the surface design of the material combinations as well as ecological and economic requirements can be met with the fastening device according to the invention.
- the thermal insulation value of the fastening device is significantly improved compared to purely metallic fastening devices of this type.
- a non-metallic material such as wood, plastic or other such materials, which has a significantly lower coefficient of thermal conductivity
- the entire thermal insulation property can be further optimized in the critical areas of the frame parts of such facade attachments, known as thermal bridges.
- thermal bridges Significantly better thermal insulation properties can be achieved, which play a role in particular with highly insulated multiple glazing.
- the energy efficiency and the thermal insulation properties of the building are further significantly improved with the invention.
- the fastening device according to the invention can be implemented relatively easily due to the form fit, for example by including the beam modules and corresponding counter-fastening points on the metal frame in the mold corresponding grooves or recesses are provided, so that a secure and statically effective connection of the elements, namely the beam module and the metal frame of the fastening device, is achieved through a pure form fit without the need for additional fastening methods such as gluing, screwing etc.
- other fastening means for the beam modules on the metal frame can also be provided in addition to the pure form fit.
- the fastening device according to the invention also has significant advantages with regard to fire protection requirements. Due to the hybrid structure, more fire-hazardous elements such as the wooden beam modules can be positioned completely inwards from the outside, and only metal elements can also be used in the connection points to the building ceilings. No materials that are dangerous in this respect, such as wood or plastic, are necessary at the transition between the floors of buildings, which is critical for fire.
- the beam modules can be easily separated from the metal frame.
- the respective materials can be disassembled again in recycling without any problems arising when disposing of such building materials.
- the fastening device according to the invention offers good and thermally highly insulated sealing of the weather side inwards with improved thermal insulation overall for the entire building at the points on the frame parts that are usually critical as thermal bridges.
- the invention also allows the beam modules to be used in different types and shapes, as well as sizes and dimensions, without costly modifications, so that there is great variability in the construction of the fastening devices for facade elements. Different shapes, sizes or materials can be used so easily, without the basic construction and thus the actual manufacturing process of the fastening device and the assembly having to be modified by the positive fit in a costly manner.
- a beam module i. H. an element consisting essentially of a solid material, such as a wooden beam or a beam made of another non-metallic material, is provided, which is firmly connected to the fastening device and its metallic components at at least two points by the form fit with the supporting section of the metal frame in the assembled state is.
- the beam module acts as a statically supporting part in addition to the supporting metal frame, which as a result has to have a less pronounced construction and shape.
- Relatively filigree facades can thus be realized.
- the fastening device nevertheless has a sufficiently high flexural strength and is provided with material properties that are significantly improved in terms of thermal insulation thanks to the non-metallic beam module.
- the at least two fastening points for the beam module on the support section of the metal frame are preferably provided in a section lying parallel to the facade surface and in a section of the metal frame projecting at right angles to the inside of the facade. With such a crossed arrangement of the fastening points, an even better rigidity of the facade fastening as a whole is achieved.
- the support section of the metal frame essentially has an L-shape in cross section corresponding to a shape and width of the beam module for receiving it on the metal frame in a manner corresponding to the shape. up.
- the beam module thus rests flat on the side surfaces of the support section of the fastening device in at least two planes, so that an even better statically effective connection to increase the stability of the construction at the connection points of the facade elements in two directions, namely in the direction of the plane of the facade element and once at right angles to the direction of the façade element.
- a high degree of flexural rigidity and torsional strength of the fastening device is achieved with the solution according to the invention.
- the L-shape does not have to be an exact L-shape and can vary according to the shape of the respective beam module that is attached to the attachment points:
- the respective width and side surface of the beam module can be taken into account in such a way that complete coverage towards the inside into the interior is achieved through the beam module.
- the beam module is provided with correspondingly shaped recesses or grooves corresponding to a shape of holding webs or fixing projections of the fastening points on the metal frame or on the supporting section of the metal frame for pushing or plugging on the beam module.
- the recesses or grooves which can easily be milled into a wooden beam, for example, are provided essentially over the entire longitudinal extension of the respective beam module and in a shape corresponding to the respective holding webs or fixing projections of the projections or attachment points on the metal frame. In this way, by simply pushing on the beam modules, the modules can be attached to the support section of the metal frame in a form-fitting and flush manner.
- Production is therefore relatively simple and not very expensive, and it can also be easily prefabricated in a production process away from the installation site. Last but not least is It is also possible to reuse the individual elements for recycling, since the type-free disposal of different materials is possible by simply removing the beam modules from the metal frame parts.
- the beam module essentially has an L-shape in cross section with an L-leg that covers the metal frame on the inside of the facade.
- the Baiken module can completely cover the metal frames towards the inside of the facade (inside of the building) on several levels and in several directions. This means that the metal base construction of the fastening device is no longer necessarily visible from the inside.
- the overlapping with the beam modules also has the advantage that the contact surfaces between the beam module and the metal frame are provided on several levels and in several directions perpendicular and longitudinal to the façade plane, which in turn increases the rigidity, bending strength and torsional rigidity of the assembled fastening device.
- the fastening device is thus even more stable than before, despite the significantly improved values in terms of thermal insulation, sustainability (C0 2 neutrality) and the possibility of recycling the individual, unmixed elements.
- the beam module is a wooden beam or a beam made of a wood material, in particular a wood composite material.
- the beam module can thus advantageously be formed from a wooden beam, for example from solid wood, or from a material realized by layers of wood or wood chips, such as. B. chipboard, MDF or similar.
- the beam module can also be a wood composite material in which several layers of wood or wooden sticks are glued together to ensure the longevity of the beam module. Heating materials with, for example, plastic parts can also be used as a composite material.
- a beam module formed in this way has the advantages of a wooden material, in particular a significantly improved thermal insulation value, sustainability in production, easy processing for the production of the bond with the metal frame and overall lightness compared to other materials such as metallic materials .
- the use of different materials such as wood for the Baiken module also has the advantage that with regard to the design of the Interior further options and freedom in the construction are offered. Different rooms with differently designed fastening devices and differently formed bar modules can also be easily realized in this way, since individual elements can be exchanged without any problems simply by attaching the bar modules. A complete module construction for the facade assembly is thus provided.
- the beam module is arranged at a distance from a weather-side seal of the fastening device in the direction of the outside of the facade. This ensures that the beam module does not come into direct contact with external weather influences such as moisture, cold or heat.
- the outside of the facade and the fastening device for the facade is essentially realized by parts that are not critical to the weather, namely the facade retaining element, an L-shaped retaining element made of plastic with reduced heat conduction and the glass elements themselves as facade elements.
- the statically effective beam module itself which can be a wooden module, is arranged at a distance from the seal to the outside between these elements and the inside of the building, so that no adverse effects from moisture, moisture or weather conditions can arise here on the beam module .
- the beam module is arranged at a distance from the facade element itself by a section in the form of a hollow chamber of the metal frame.
- the beam module is arranged essentially directly adjacent to the facade element or to a seal of the facade element.
- the construction of the metal frame can be completely covered to the inside by the beam module. This results in larger statically effective areas of the form-fitting connection between the facade element and the beam module, in several levels. This further increases the stability and flexural rigidity of the entire fastening device.
- only the beam module itself can be seen as a visible element on the inside, and the structure of the metal frame underneath is completely covered by the beam module. This increases the choice of material for an interior design.
- At least one of the fastening points of the fastening device serving for the form fit is realized in the form of a kind of dovetail connection.
- the dovetail connection can be realized, for example, in such a way that in the support section of the metal frame there is a projecting web that widens conically outwards and that a corresponding groove widening conically inwards is milled into the beam module.
- the beam module can be fixed simply by plugging it on, and with such a fixing point in the form of a dovetail connection, fixing is not only achieved in one direction (perpendicular to the plane of the facade element), but in two directions, i.e. also in a parallel direction reached to the level of the facade element.
- the dovetail connection thus increases the stability of the connection and the stability of the fastening device overall with regard to the flexural rigidity, which is an essential point for facade elements of this type.
- At least one of the attachment points serving for the form fit is realized in the form of a tongue and groove connection.
- This type of connection for the positive fit between the beam module and the metal frame has the advantage that a secure plug-in connection can be achieved by simply milling a straight groove over the entire longitudinal extent of the beam module and by providing a simple, protruding, straight web on the support section of the metal frame is achieved by plugging in or pushing in.
- the form fit can thus be ensured with relatively simple means.
- the two attachment points can also have alternative configurations with regard to a positive fit, as long as they enable a positive connection and fixation to increase the flexural rigidity.
- the facade element comprises multiple glass insulating glazing with at least two, preferably three panes of glass. This further increases the insulating effect of the facade elements.
- the fastening device for the facade element, together with the high thermal insulation properties of the glazing has an overall improved thermal insulation value, so that it does not, particularly in the critical corner areas of the frame parts, which normally have a lower temperature than the plastic parts or seals due to the metal to critical areas with moisture, condensation, etc.
- the facade element can also include other elements that are attached to facades, for example metal or stone slabs, individual elements or the like.
- the fastening device according to the invention has the advantage that due to the beam module on the inside of the fastening device, it has a significantly better thermal insulation value than other conventional fastening devices of this type with a frame construction made of essentially metallic elements.
- the L-shaped holding element on the outside of the fastening device consists of a plastic or a plastic composite material and is detachably fastened to the metal frame by means of screws that can be countersunk inside the holding element.
- the facade elements can be prefabricated in a factory together with the beam module, the metal frame and the facade element (glazing) and then easily fixed in place using the holding elements. This allows a fully automated prefabrication to be implemented, which is too clear leads to lower costs than assembling the individual elements, support elements, facade elements, sealing elements and holding elements, etc. on site.
- sealing seals are provided on the beam module or on the support section of the metal frame towards the inside of the fastening device.
- the seals prevent the ingress of dust, moisture or the like.
- the seals enable vibrations or movements between the individual elements of the fastening devices to be supported and cushioned on the inside, in particular in conjunction with the beam module. They also prevent the cold from penetrating into the interior of the building.
- retaining clips made of metal or spring steel are provided between the metal frame and the facade element, which have a first leg for overlapping the facade element on its front side or outside and a second leg for engaging with or for Have applying to the holding portion of the metal frame.
- the holding clamps formed in this way serve to cushion and secure the fastening device on the facade elements. This absorbs the sometimes very high compressive forces, lateral forces and movements of the individual elements of a building facade and effectively cushions them through the elasticity of the retaining clips.
- the fastening device has an even more secure strength, high stability and flexural rigidity with nevertheless the best possible cushioning of forces and movements of the construction elements that occur.
- the retaining clips are a type of statically effective link between the facade element and the retaining structure. The mechanical security improved in this way guarantees that the glass panels are safe from falling.
- the invention is also directed to a fastening device for facade elements according to claim 15.
- the fastening device which is used in particular for assembling and fixing glass facades on buildings, has a metal frame and an L-shaped holding element which, on the outside, surrounds the facade elements, for example the window panes, with the metal frame having at least one Hollow chamber is provided and a facade holding section as well has a support section pointing inwards from the facade element from a facade outside essentially perpendicularly to the plane of the facade elements, the fastening device being characterized in that on the inside of the support section a fastening point is attached by positive locking at at least two spaced apart fastening points Beam module or a cover profile made of at least partially non-metallic material is provided, which extends at least in sections over the length of the respective metal frame and which is coupled to the metal frame on an inner side of the facade element in such a way that it is in the installed state of the fastening device by the Form-fitting or by the fixation at the at least two attachment
- connection elements such as beam modules, profiles or similar by means of a form fit at the two spaced attachment points, so that an increase in bending and torsional rigidity is possible even with such a combined use of different materials for the beam modules, the cover profiles etc. is given.
- a beam module consisting of a wooden beam can also be attached to a central metal frame of such a fastening device according to the invention on the one hand by the two attachment points via form-fitting connections, while a cover profile made of aluminum profile is attached to the opposite second side. via one and the same attachment points and fasteners.
- the various individual components can also be modified and rebuilt on site as required.
- the modular design also makes it possible to easily repair individual elements after damage or after a conversion.

- screw channels are provided on the support section of the metal frame of the fastening device at the same fixed positions and in identical shapes for flexible and modular mounting and accommodation of beam modules, cover profiles, fixing elements or end profiles.
- the end profiles and the beam modules can thus be easily fixed and attached to the respective screw channels on the metal frame of the fastening device. It is not necessary to use different metal frames or extra fixings such as screws, depending on whether beam modules, aluminum cover profiles or connection profiles for further connection elements or technical equipment are to be provided on the corresponding insides of the fastening devices.
- end profiles for example, profiles can be used in the screw channels, which are used to accommodate lighting devices such. B. LED strips etc., or other technical functional elements are used.

- the beam module 4 is preferably a beam module 4 made of wood or a wood-based material, but can also contain other non-metallic materials.
- the beam module 4 is connected to the support section 13 of the metal frame 1 via a positive fit at at least two attachment points 7, 8, ie by the elements and recesses of the beam module that correspond to the shape! 4 at the respective fastening points 7, 8, the beam module is mounted on the metal frame 1 by simply pushing or plugging it.
- the positive connection is ensured in such a way that the beam module 4 also rests against the surfaces of the essentially L-shaped support section 13 in a corresponding shape and configuration in two mutually perpendicular planes.
- the beam module 4 in this exemplary embodiment is also essentially L-shaped, so that it slightly overlaps the metal frame 1 at the end section on the inside of the facade element 2 .
- the beam module 4 is also formed in such a way that it also protrudes in the direction of the facade element 2 in the form of the three glass panes 3 up to the glass panes 3 or a seal from them—that is to say a double -L-shape for a flat form fit. In this way, an even larger surface of the form fit between the beam module 4 and the metal frame 1 and thus a higher static effectiveness of the beam module 4 is achieved.
- the metal frame 1 is made from a metal material such as aluminum using an extrusion process
- the additional stability and flexural strength of the fastening device 10 is achieved with a bar module 4 made from a non-metal material and attached via a form fit.
- a better thermal insulation property can be achieved with a sufficiently high flexural strength, which is an essential factor for facade elements or fastening devices 10 of this type.
- the flexural rigidity is ensured in that the beam module 4 is mounted with the support section 13 of the metal frame 1 in a form-fitting manner at at least two fastening points 7, 8 provided at a distance from one another.
- the fastening point 7 is realized with a form fit in the manner of a dovetail connection, in that on the metal frame 1 there is an outwardly widening holding web (FIG. 1) or a conically widening holding web made of solid material (FIG. 2 and FIG. 3) and a groove corresponding to the shape is provided on the beam module 4.
- a simple tongue/groove connection is provided at the fastening point 8 between the bayen module 4 and the support section 13 of the metal frame 1 . This can be produced in that a continuous groove extending over the entire length is machined in the beam module 4 in accordance with the shape and dimensions of the protruding web at the attachment point 8 of the metal frame 1 .
- the shapes and the type of different possible positive connections at the attachment points 7, 8 can vary according to the invention. Also can more than two attachment points 7, 8 can be provided between the metal frame 1 and the beam module 4, as long as the connection and assembly takes place via a positive fit.
- the beam modules 4 are implemented as wooden elements, for example, so that they offer a high level of sustainability, CO2 neutrality and very good thermal insulation properties in addition to the thermal insulation provided by the L-shaped holding element 5 made of non-thermally conductive material for the fastening device 10 as a whole. An improved thermal insulation value can thus also be achieved on the inside of the building, as was previously not possible with purely metallic frames 1 of this type of fastening devices 10 .
- the invention offers further advantages in terms of improved recyclability.
- unmixed materials such as e.g. B. wood for the beam module 4 and aluminum for the metal frame 1
- the individual parts of the fastening device 10 can be easily recycled in an environmentally friendly manner when disposed of without great effort.
- the sustainability of using wood as a material for the Baiken module 4 is also very high, and CO2 neutrality, which is also becoming more and more relevant in the construction industry, can be significantly improved.
- the fastening device according to the invention nevertheless has the strength values required for such glass facades, in particular high torsional rigidity and flexural strength.
- the beam modules 4 do not have to have other expensive separate fastening elements, such as e.g. B. screws or adhesives, are mounted on the metal frame 1.
- the use of screws as fasteners would in any case lead to an undesired weakening of the material and the core of the beam modules 4, which in turn are bad for an assembly of, for example, comparatively thin wooden elements as beam modules 4 the indoor rooms of such buildings significantly increased.
- Different shapes of beam modules can be used as required, without using fasteners such as screws from the inside, for example to create wooden interiors in the building.
- the beam module 4 designed in the form of wood can also completely cover the metal frame 1 on the inside up to adjacent to the facade element 2 .
- the metal part of the metal frame 1 is almost completely covered from the inside and is therefore invisible.
- other elements can also be attached to the beam modules 4, which was not easily possible with previous fastening devices 10 consisting of pure metal.
- additional functions and components or elements can easily be attached to the inside of the beam module 4 without requiring complex screw connections or the like.
- the fastening device 10 according to the invention is produced by simply milling out grooves in the beam module 4 that correspond in shape to the fastening points 7, 8 and by extrusion or continuous casting of metal profiles made of aluminum, for example, for the metal frame 1 in the corresponding form of the form-fit connection elements on the fastening points 7, 8. Then the beam module 4 can be firmly mounted in the appropriate length to the metal frame 1 simply by sliding it onto the fastening device 10 and is immediately ready for use and statically effective in the finished building.
- the fastening devices 10 according to the invention can thus be prepared very well in series in a manufacturing process and then only have to be assembled on site in the conventional manner, namely by mounting and fixing to a frame of the shell construction or to the shell of the building itself.
- the beam module 4 is arranged at a distance from the inside of the facade element 2 by a section of the facade holding section 12 in the form of a hollow chamber 14 .
- This spacing can prevent any residual moisture, which frequently occurs in the corner areas of glass facades of facade elements 2, from reaching the beam modules 4, which are realized in the form of wood, for example. This ensures long-term durability and strength of the material of the beam modules 4 performs.
- the beam modules 4 can also be made of materials other than wood or wood composites: for example, beams made of plastic, stone, glass or other recycled products can be used to vary the interior design of the building as required.
- the beam modules 4 are preferably made of a material with better thermal insulation properties compared to metal and are made, for example, of a plastic or of wood, for example solid wood. Beam modules 4 of this type can easily be attached to the support sections 13 of the metal frames 1 by means of a form fit with corresponding tongue and groove connections, dovetail joints or other form-fitting connection methods.
- a retaining clip 15 is also attached to the facade hat section 12 of the metal frame 1 on the side of the facade element 2, the latter being overlapped on the outside by the retaining clip 15 and a spring effect on one side of the metal frame 1 or the retaining element 5 offers.
- the brackets 15 have a slightly bent V-shape on us z. B. realized as stainless steel leaf springs. As a result, the forces can be better absorbed even in strong gusts of wind or the like, and the strength and stability of the fastening device 10 is further increased. This additional mechanical safeguard also ensures that the façade parts are safe from falling.
- the holding element 5, which is essentially L-shaped in cross section and which is attached to the metal frame 1 with countersunk screws 11 on the outside of the facade element 2, is preferably made of plastic.
- Plastic has a lower thermal conductivity than metal, so that the formation of thermal bridges is also prevented here and an even better thermal insulation property can also be offered in the area of the fastening device 10 .
- FIGS. 4 to 10 represent further exemplary embodiments according to the invention to illustrate the high degree of modularity and diversity in the adjustment options of the fastening device 10 according to the invention with different beam modules 4 or cover profiles 16 and different shapes of metal frame 1.
