Description

[0001] The present invention relates to a glass support system according to the preamble of claim 1. Technological background

[0002] Building facades consist of facade profiles with a regular or irregular geometric cross-section. These facade profiles form the load-bearing part of a facade system. The facade is designed to support its own weight, in whole or in part, and does not offer alternative load paths for a building's structural loads. In addition, facades bear wind loads acting on the building, which include suction forces or compressive forces, but can also transfer snow loads. The facade profiles of the facade system support the weight of the infill elements, which are usually transparent, translucent, or opaque, with the help of specific fastening elements such as glass support systems or other fastening systems. These fastening elements serve as a flat base for the infill elements and transfer their weight to the facade profile by subjecting them to shear, tensile, and / or bending stresses.The fasteners are typically positioned within the profile channel and connected to the façade profile either by screwing, hammering, or, in some cases, welding. In some special configurations, the fastener is docked into the channel and holds itself in place due to its geometric shape, eliminating the need for additional screws, welds, etc.

[0003] WO9618778 A1 is known from the prior art. A profile system with thermal break means, intended for glazed facades, consists of intersecting inner elongated structural profile elements, which are provided on their outward-facing side with a longitudinally extending groove for receiving lug heads to hold window panes against the structural profile elements. Rubber sealing strips are arranged between the inner structural profile elements and the adjacent window panes. The sealing strips have no interruptions and are formed with a web portion mounted in the grooves of the structural profile elements and with a flange portion on either side of the web portion. The flange portions rest between the structural elements on either side of the groove and the adjacent window panes and are pressed together to form a seal.

[0004] KR 2020 / 0068834 A is known from the prior art. This discloses a mounting structure for a glass support of a curtain wall, in which an insulating material is inserted between an inner frame and the forward-projecting glass support to support glass or to be positioned at an edge of the glass in a horizontal beam and a vertical beam of the curtain wall. The frame and the insulating material are automatically mechanically coupled to each other using a knurling process.

[0005] The disadvantage of the known solutions is that the thermal insulation materials are prefabricated and inserted into the grooves of the facade profiles during the production of the facade systems.

[0006] DE 101 44 551 A1 is known from the prior art. This discloses a post-and-beam framework with fire protection elements for a building. The fire protection elements have a core element surrounded by a thermally insulating filler and a cladding, namely a metal profile. A screw channel is arranged in the core profile. The fire protection element has a cover strip which is fastened to the core profile with a fastening screw. Components can be clamped between the cover strip and the end face of the cladding of the fire protection element, whereby the cover strip presses on the clampable components when the fastening screw is screwed into the screw channel located in the filler. During installation of the clampable components, only the fastening screw is screwed into the fixedly positioned core profile until a desired clamping force acts on the clampable components.

[0007] The disadvantage of the known solution is that the cladding is completely filled with filler on the inside, completely accommodating the core profile. The filler is poured into the cladding during the production of the fire protection elements and serves only as a fire protection compound.

[0008] GB 2551 55 13 A is known from the prior art. This discloses a facade system with a metal facade profile and a plastic support. The facade profile has a channel-shaped receptacle for partially receiving the plastic support, wherein the channel-shaped receptacle extends at least along the longitudinal extent of the facade profile. The plastic support is inserted into the channel-shaped receptacle. The plastic support has support lips and the channel-shaped receptacle has projections. The channel-shaped receptacle is filled with an at least temporarily flowing foam material, wherein the foam material, when cured, completely fills the channel-shaped receptacle. After filling, the foam material expands throughout the channel-shaped receptacle and hardens, so that the support lips of the plastic support are pressed against the projections in the channel-shaped recess.

[0009] The disadvantage of the known solution is that the plastic support must be pulled, pushed, or inserted along the length of the channel-shaped support. Furthermore, the entire cavity of the channel-shaped support must be filled with the foam material, and a virtually permanent pressure must be exerted on the plastic support to prevent it from slipping relative to the facade profile.

[0010] KR 2014 0015873 A1 is known from the prior art. This discloses a multi-part glass support system for mounting on a channel-shaped support of a facade profile. It includes at least one connecting element, a cover, and a support element, with the support element serving to accommodate a cover fastening screw.

[0011] The disadvantage of the known solution is that the support element only transmits horizontal forces to serve as an anchor for the cover fastening screw.

[0012] KR 101 630 197 B1 is known from the prior art. This discloses a glass support system for mounting on a channel-shaped receptacle of a facade profile. The glass support system comprises at least one glass support plate, a connecting element, and a thermal bridge arranged in the channel-shaped receptacle.

[0013] The disadvantage of the known solution is that the connecting element itself is not load-bearing when it is suspended at the bottom in the channel-shaped holder of the facade profile. The glass support plate suspended at the top in the facade profile exerts a horizontal compressive force on the connecting element, which stabilizes the glass support system. The connecting element alone cannot absorb vertical loads. Description of the invention

[0014] One object of the invention is to avoid at least one of the disadvantages of the prior art and to create a facade system in which the rigidity and load-bearing behavior of a fastening element is improved. Furthermore, an improved assembly method is to be created, with which, in particular, the rigidity and load-bearing behavior of a fastening element on an existing facade system is improved, as well as an improved glass support system with improved rigidity and load-bearing behavior.

[0015] This problem is solved by the features of the independent claims. Advantageous further developments are set forth in the figures and in the dependent claims.

[0016] A facade system according to the invention comprises at least one facade profile and at least one first fastening element, wherein the at least one facade profile has at least one channel-shaped receptacle for at least partially receiving the first fastening element or is connected to at least one channel-shaped receptacle for at least partially receiving the first fastening element, wherein the at least one channel-shaped receptacle extends at least along the longitudinal extent of the at least one facade profile, and wherein the first fastening element is inserted and positioned in the at least one channel-shaped receptacle. The at least one channel-shaped receptacle can be filled, at least partially, with an at least temporarily flowing support agent, wherein the support agent, in the cured state, supports the first fastening element at least partially in the at least one channel-shaped receptacle.

[0017] The at least one channel-shaped receptacle on the facade profile can be filled with the at least temporarily flowing support agent during manufacture as well as during final assembly of the first fastening element of the facade system, wherein the at least one channel-shaped receptacle is designed or formed to hold the temporarily flowing support agent in the liquid state locally at the intended support position in the at least one channel-shaped receptacle, such that the support agent in the solid, cured state directly or indirectly supports the first fastening element, thereby improving the rigidity, strength and load distribution behavior in the connection between the at least one channel-shaped receptacle and the first fastening element in the facade profile. In this case, an initially pressure-free abutment is created which acts against rotation of the first fastening element in the channel-shaped receptacle relative to the facade profile.The at least temporarily flowing support agent can be injected into the at least one channel-shaped receptacle, for example, using an injection tool, such as a spraying tool. This enables precise filling. This greatly improves the load distribution behavior between load-bearing and load-dissipating components in the facade system. The at least temporarily flowing support agent has a finite stiffness and strength in its solid state. The facade system can be a metallic or non-metallic facade profile and comprise aluminum, steel, wood, or plastic. The thick welded seams between the facade profiles and the first fastening element, known from the prior art, can be dispensed with, so that the facade profile uses less material and is therefore lighter in construction and less labor-intensive.In the case of powder-coated facade profiles, subsequent welding is not desired.

[0018] The temporarily flowing support agent in the channel-shaped receptacle, when cured, at least doubles the nominal load-bearing capacity of the first fastening element and, in particular, doubles the rigidity of the connection to the first fastening element, thereby improving load-bearing performance. The maximum deformation of the first fastening element is typically limited, since otherwise the first fastening element would sink so far under load that it would rest on a facade filler element, for example, on the lower glazing of the facade. Therefore, in the embodiment according to the invention, an increase in the rigidity of the connection leads to an increase in the usable load-bearing capacity of the first fastening element.

[0019] Reducing the weld thickness on the facade profile not only reduces manufacturing and installation time, but also improves the aesthetics of the facade.

[0020] In a preferred embodiment, the at least temporarily flowing support material is arranged on the outside of the facade profile in the at least one channel-shaped receptacle. This allows the facade profile to be filled inside, for example, with a fire protection compound or simply left empty.

[0021] The facade profile can have a regular or irregular cross-section. The at least one channel-shaped receptacle can be curved to complement a tubular facade profile with a circular cross-section. This also applies to configurations in which the at least one channel-shaped receptacle is welded or bolted to an open profile such as a C- or U-shaped profile or similar configurations. The at least one channel-shaped receptacle can have non-parallel surfaces or partially curved or straight surfaces and can be welded or bolted to the facade profile.

[0022] The at least one channel-shaped receptacle can be circular, triangular, conical, trapezoidal, open or closed polygonal, partially curved, or have a regular geometry with multiple non-parallel surfaces, or have an irregular geometry. The at least one channel-shaped receptacle can consist solely of a groove formed from two parallel surfaces. The at least one channel-shaped receptacle can be irregularly shaped, or have a fractal geometry to improve adhesion, or contain regular and irregular patterns that ensure better interaction with the at least temporarily flowing support medium and the first fastening element. The at least one channel-shaped receptacle can, for example, be a screw channel for receiving a screw.

[0023] Preferably, the at least one channel-shaped receptacle has at least one limiting element. The limiting element forms a barrier for the at least temporarily flowing support agent, preventing it from undesirably spreading along the channel-shaped receptacle. Thus, in the cured state, the support agent acts only in the designated area of ​​the channel-shaped receptacle. Advantageously, the limiting element consists of a non-foamed or foamed molded piece, such as LDPE (low-density polyethylene). Such limiting elements are easy to manufacture and easy to install in the at least one channel-shaped receptacle.

[0024] In particular, the first fastening element comprises at least one glass carrier plate. Glass carrier plates or glass supports are used to allow facade infill elements to rest on facades and thus be attached to the facade. Such fastening elements have a load-bearing effect. Typically, the facade glass is additionally fixed to the facade with glazing beads or connecting studs. The aforementioned facade system with a glass carrier plate as the first fastening element improves load transfer within the facade system. The horizontal and vertical load transfer and stabilization of inclined and horizontal glazing elements are also improved with the glass carrier plate.In particular, the first fastening element may be made of steel, stainless steel, bronze, magnesium alloys, aluminum or non-metallic materials such as thermoplastics, high-strength polymers, or organic materials such as bamboo, wood, conditioned / unconditioned wood or composite materials such as fiber-reinforced polymers.

[0025] Preferably, the first fastening element can be inserted and positioned into the at least one channel-shaped receptacle in a direction perpendicular to the longitudinal extent of the facade profile. The first fastening element therefore does not have to be pulled, pushed, or inserted along the longitudinal extent of the channel-shaped receptacle, as is known. This enables simple assembly, particularly on a construction site, wherein the first fastening element can be positioned with pinpoint accuracy in the at least one channel-shaped receptacle from the outside toward the support position in the at least one channel-shaped receptacle, in order to be stabilized in a subsequent step with the at least temporarily flowing support medium. Retrofitting existing facade systems with fastening elements is simplified.

[0026] Preferably, a second fastening element is provided, which is inserted and positioned in the at least one channel-shaped receptacle, wherein the support means, in the cured state, directly supports the second fastening element at least in sections. This further improves the strength and rigidity of the connection between the at least one channel-shaped receptacle and the first fastening element in the facade system.

[0027] Preferably, the second fastening element accommodates the first fastening element at least in sections. The second fastening element supports the first fastening element, thus further improving the rigidity of the facade system. Furthermore, greater load-bearing capacities, for example heavy glazing, can be carried by the fastening elements. For example, the second fastening element is a clamping foot or a T-nut, clamping knob or the like, and the first fastening element is a glass carrier plate or a support plate. The glass carrier plate can be inserted into the clamping foot so that it is accommodated in sections by the clamping foot. The clamping foot enables surface support of the glass carrier plate or the support plate along the edge of the at least one channel-shaped receptacle, thus enabling greater load-bearing capacities and rigidities in the load transfer.

[0028] Preferably, at least one of the two fastening elements has at least one fastening sleeve for receiving a fastening means, wherein the fastening sleeve penetrates at least partially into the at least one channel-shaped receptacle. In this case, a fastening sleeve is also a receiving opening for receiving a fastening means, for example, for a bolt, a screw, or the like. Thus, at least one of the two fastening elements can be positioned in the at least one channel-shaped receptacle using one or more point contacts.

[0029] In particular, the support means, in the cured state, directly supports the fastening sleeve and / or the fastening means in sections, thereby improving the rigidity and strength of the connection between the at least one channel-shaped receptacle and the fastening sleeve and / or the fastening means in the facade system. The cured support means presses on the fastening sleeve and / or the fastening means, preventing them from being pulled out of the at least one channel-shaped receptacle. This prevents the occurrence of localized plastic zones, further improving the rigidity and strength, and making the connection more compact overall.

[0030] Preferably, at least one of the fastening elements and / or the at least one facade profile has at least one opening for filling the at least temporarily flowing support agent. This allows the support agent to be precisely positioned at the support position in the liquid or flowing state. An opening in the facade profile can also be designed as a fill level control opening, so that the amount of at least temporarily flowing support agent to be filled can be easily controlled. An opening in the first fastening element can serve to position the at least temporarily flowing support agent and simultaneously use the opening as a fastening opening for a fastening element.

[0031] Preferably, at least one of the fastening elements has an external surface structure, so that the connection between at least one of the fastening elements and the support means is improved in the cured state. The support means can adapt to the external surface structure in the flowing state, so that relative movement between the support means in the cured state and the external surface structure is prevented due to the resulting static friction or form-fitting or mechanical locking or interlocking.

[0032] Alternatively or additionally, at least one of the fastening elements has an internal surface structure, so that the connection between at least one of the fastening elements and a fastening means or the support means is improved in the cured state. The support means can adapt to the internal surface structure in the flowing state, so that relative movement between a fastening means or the support means in the cured state and the internal surface structure is prevented due to the resulting static friction, positive locking, or mechanical interlocking.

[0033] Alternatively or additionally, at least one fastening sleeve has an inner and / or outer surface structure, so that the connection between the fastening sleeve and a fastening means or the support means is improved in the cured state. The support means can adapt to the outer surface structure in the flowing state, so that relative movement between the fastening sleeve or the support means in the cured state due to the resulting static friction / positive fit is prevented. The inner surface structure improves the strength between the fastening sleeve and the fastening means or the fastening element.

[0034] The fastening elements can have tribological internal and / or external surface structures, such as grooves, wave-like shapes, rough textures, crater-shaped depressions, patterns with depressions and elevations or other shapes with tribological advantages that lead to better contact with the support material.

[0035] A fastening element in this case is a component that is directly or indirectly supported by the support means in the cured state, such as a load-bearing element, such as a glass carrier plate and / or a clamping foot, a T-nut and / or a screw, a bolt and / or a sleeve and / or a T-connector and / or a corner connector and / or a cross connector for connecting facade profiles or the like.

[0036] Preferably, the at least one channel-shaped receptacle has an internal surface structure so that the connection between the at least one channel-shaped receptacle and the support means is improved in the cured state. The support means can adapt to the internal surface structure in the flowing state so that relative movement between the support means in the cured state and the internal surface structure in the at least one channel-shaped receptacle is prevented by static friction and / or by positive locking or mechanical interlocking. The at least one channel-shaped receptacle can have tribological surface structures such as grooves, wave-like shapes, rough textures, crater-shaped depressions, patterns with depressions and elevations, or other shapes with tribological advantages that lead to better contact with the support means.

[0037] Preferably, the support means is arranged in the at least one channel-shaped receptacle, wherein the support means can already be present in the cured state or be present in an intermediate state in which it only develops its full support stability with a time delay. Without support means, the contact surfaces of the first fastening element generally do not have uniform contact in the at least one channel-shaped receptacle over the embedded channel length and therefore have individual support points. In such cases, localized plastic zones can form on the connecting parts and the connection as a whole has limited stiffness and strength. This leads to an uneven load distribution between the contact surfaces of the connection. In the cured state, the support means effects a surface and / or surface-like support contact, thus improving stiffness and strength.Furthermore, an increase in the pull-out capacity of the first fastening element in inclined facade profiles can be observed. The support material can, for example, be a filler without adhesive properties, whereby the filling volume in the at least one channel-shaped receptacle is increased. The filler is intended to increase the strength of the connection in the at least one channel-shaped receptacle, fill the volume around the first fastening element, and increase the compactness and overall rigidity as well as the strength of the connection. This results in an increase in the directional load-bearing capacity of the first fastening element or also of the second fastening element in the facade system.

[0038] A preferred support means is an at least temporarily flowing mortar that is injected or introduced during the fastening process between the first fastening element and a cavity of the at least one channel-shaped receptacle. This flowing mortar fills the free space around the contacting surfaces and, after curing, exhibits a finite stiffness and strength. The additional volume of the mortar makes the connection more compact and ensures better load distribution around the contacting parts. As a result, the entire connection is relatively stiffer and can withstand heavier loads with relatively less deformation. This is generally advantageous if the manufacturer uses the fastening element for infill loads that are close to its ultimate load-bearing capacity or deformation limit.Depending on its thermal properties (density, specific heat and thermal conductivity, microstructure, etc.), the mortar can also act as a facilitator for heat flow. Mortars that provide thermal insulation or high thermal resistance to heat flow, as well as mortars that are fire-resistant and flame-retardant, are preferred. The same applies to mortars that can also be used for sound insulation and / or vibration insulation.

[0039] The mortar is advantageously in powder or granular form as a support agent, which can be processed by mixing it with organic or inorganic binders / universal solvents, such as water. In this state, the flowing or viscous mortar can be poured into any desired shape and reaches a final strength after hardening. The mortar can comprise a hydraulic binder, be cement-based, gypsum-based, lime-based, a polymer-based, or rubber-based resin, or contain fiber-reinforced cement mortars, fiber-reinforced resins, self-curing binders, UV-curing binders, or naturally occurring binders, and can be organic or inorganic.

[0040] Advantageously, the at least temporarily flowing support agent comprises an adhesive component. The at least temporarily flowing support agent therefore acts not only as a mechanical support, but also as an adhesive, which creates a material-to-material connection between the first fastening element and the at least one channel-shaped receptacle. In the cured state, this creates a non-slip connection with the surrounding surfaces in the at least one channel-shaped receptacle of the facade profile and the fastening element, i.e. there is no relative sliding during injection or later in the final state. The adhesive component can comprise an adhesion promoter, which is particularly effective in the case of oiled or powder-coated facade profiles. Alternatively or additionally, the support agent comprises a hardener, so that the time course from the liquid state to the cured state is shortened, thus simplifying assembly and installation.the manufacture of the facade system is accelerated. Alternatively or additionally, the support means comprises a solvent. The solvent ensures that the support means remains fluid for a sufficiently long time so that it can be precisely positioned on the support surfaces in the at least one channel-shaped receptacle. The solvent typically evaporates during the curing process of the support means. Advantageously, the support means is designed such that it only forms a material bond with the material of the at least one channel-shaped receptacle and only supports the first fastening element. The first fastening element can therefore still be positioned after assembly.

[0041] The at least temporarily flowing support material can have a high viscosity, e.g., a cement-based mortar, which has a high consistency and high flow resistance. Such a viscous support material can be injected into a horizontal or vertical facade profile channel with plastic or metal plugs as limiting elements at the ends to secure the at least temporarily flowing support material before and after the fastening element is applied.

[0042] The at least temporarily flowing proppant preferably comprises fibers. The fibers can comprise various materials, such as plastic, glass, metal wool, or the like, and / or have various shapes—for example, straight, corrugated, or bent. The at least temporarily flowing proppant can also contain other fillers, such as inert fillers (e.g., sand), reactive fillers, staggered two-stage hardening, or accelerated hardening of the fillers. The fibers do not change their shape and geometry, even after moderate cracking in the cured proppant, bridging cracks or bearing loads, so that the improved strength is maintained.

[0043] Preferably, at least one ventilation opening is provided to improve the curing of the at least temporarily flowing support material. The ventilation opening can be located on the first fastening element or on the facade profile and, if necessary, can also be indicated only as a marking, allowing this ventilation opening to be opened subsequently using a tool if necessary.

[0044] The facade system preferably comprises a further facade profile, wherein the further facade profile has at least one further channel-shaped receptacle for partially receiving the first fastening element, and wherein the at least one further channel-shaped receptacle extends at least along the longitudinal extent of the further facade profile, and the first fastening element is arranged at least partially in the channel-shaped receptacle of the further facade profile. This allows, for example, corner connectors to be produced for connecting the horizontal and vertical profile elements of traditional facade systems. These transfer horizontal and vertical loads from the horizontal (first) facade profile to the vertical (further) facade profile in a facade system.Due to manufacturing tolerances, the load transfer from the horizontal or vertical façade profile to the corner connector may be uneven, or the load may be concentrated in a specific area. A support system enables better and / or more even load transfer and increased stiffness. This means that manufacturing tolerances are not critical to the assembly or functioning of the connection.

[0045] An assembly method according to the invention for mounting a first fastening element in a channel-shaped receptacle of a facade profile of a facade system comprising at least the following assembly steps, in particular in the following order: a) providing a facade profile with at least one channel-shaped receptacle; b) inserting at least one first fastening element into the at least one channel-shaped receptacle; c) positioning the at least one first fastening element in the at least one channel-shaped receptacle; d) filling at least one channel-shaped receptacle, at least in sections, with a temporarily flowing support medium; e) curing the support means to support the at least one first fastening element.

[0046] The at least temporarily flowing support agent can then spread at least partially in the at least one channel-shaped receptacle and, when cured, directly or indirectly support the first fastening element via its support surfaces in the channel-shaped receptacle and on the first fastening element. In particular, the load distribution behavior between load-bearing and load-dissipating components in the facade system is greatly improved in such facade systems. The thick weld seam connections between the facade profiles and the first fastening element known from the prior art can be dispensed with, so that the facade profile has less material and can therefore be built more easily. Reducing the weld seam thickness on the facade profile not only reduces manufacturing and assembly time but also improves the aesthetics of the facade.Furthermore, an increase in the extraction capacity of the first fastening element in inclined facade profiles can be observed.

[0047] The method described here is generally advantageous when the manufacturer uses the fastener for infill loads close to its ultimate load-bearing capacity. This method can also be applied to retrofitting existing facades where thicker and heavier infills are planned following renovation, maintenance, or modernization. This method can also improve the load-bearing capacity of an incorrectly installed fastener. Depending on its thermal properties (density, specific heat and thermal conductivity, microstructure, etc.), the support material can also act as a heat flow façade enabler.

[0048] In particular, the assembly method is applied to a previously described facade system.

[0049] In particular, prior to step b), at least one limiting element is inserted into the at least one channel-shaped receptacle. The limiting element prevents undesired distribution of the at least temporarily flowing support agent along the channel-shaped receptacle.

[0050] Preferably, the at least one first fastening element is inserted into the channel-shaped receptacle in a direction perpendicular to the longitudinal extension of the facade profile. The first fastening element therefore does not need to be pulled, pushed, or inserted along the longitudinal extension of the channel-shaped receptacle, as is conventional. This enables simple installation, with the first fastening element being precisely positioned in the at least one channel-shaped receptacle from the outside to the support position in the at least one channel-shaped receptacle. Retrofitting existing facade systems is simplified.

[0051] Preferably, before step b) or simultaneously with step b), a second fastening element is inserted into the at least one channel-shaped receptacle. The second fastening element can receive the first fastening element at least in sections and thus supports the first fastening element, thus further improving the rigidity and strength of the facade system. For example, the second fastening element is a clamping foot and the first fastening element is a glass carrier plate or a support plate. The clamping foot enables surface support of the glass carrier plate or the support plate along the edge of the at least one channel-shaped receptacle. The second fastening element is preferably inserted into the channel-shaped receptacle in a direction perpendicular to the longitudinal extent of the facade profile.

[0052] A glass support system according to the invention for mounting on a channel-shaped receptacle of a facade profile, comprising a glass support plate and a clamping base, wherein the glass support plate can be connected to the clamping base. A support plate is provided that supports the glass support plate, thereby improving the strength, rigidity, and load distribution behavior of the glass support system.

[0053] In particular, the support plate penetrates the clamping foot to engage, at least in part, a channel-shaped receptacle of a facade profile. The support plate can spread the clamping foot in the area of ​​its contact opening to improve the clamping function of the clamping foot.

[0054] Preferably, a facade profile is provided, wherein at least the clamping foot and the support plate partially penetrate into a channel-shaped receptacle of a facade profile. The at least one channel-shaped receptacle on the facade profile can be filled with the previously disclosed, at least temporarily flowing support agent during manufacture as well as during final assembly of the facade system. The channel-shaped receptacle is designed or formed to locally hold the temporarily flowing support agent in the liquid state at the intended support position, so that the support agent, in the solid, cured state, directly or indirectly supports the support plate, thereby improving the strength, rigidity, and load distribution behavior in the facade profile.

[0062] The following, partly schematically illustrated embodiments of the facade system can be used for a variety of different applications, such as vertical facades, horizontal facades, overhead facade elements, sloped, curved or double-curved facades, glazing, interior partitions, exterior partitions, public assembly spaces (e.g. stadium facades, airport facades, airport glass canopies, etc.), facades or support structures for billboards or advertising walls, facades on which visual elements such as paintings, banner boards, symbols, logos, emblems or visual / electronic elements such as lights, signs, solar panels, etc. are suspended or attached.

[0063] Fig. 1 to Fig. 4 shows a first embodiment of a facade system 20 made of steel with a facade profile 21 and with a glass carrier plate 25 as a fastening element, wherein the facade profile 21 has a channel-shaped receptacle 30 for at least partially receiving the glass carrier plate 25. The channel-shaped receptacle 30 extends along the longitudinal extent of the facade profile 21, and the glass carrier plate 25 can be inserted into and positioned in the channel-shaped receptacle 30. The glass carrier plate 25 is part of a glass support system 24, which comprises a clamping foot 28, fastening bolts 26, 26a, and a support plate 27. The support plate 27 extends through the clamping foot 28 to support the glass carrier plate 25 in the assembled state. The support plate 27 spreads the clamping foot 28 in the region of its contact opening 28a in order to improve the clamping function of the clamping foot 28 in the channel-shaped receptacle 30.The clamping base 28 has receiving openings 29a for receiving and guiding the fastening bolts 26, 26a. When the glass support system 24 is assembled, the fastening bolts 26, 26a press against the inside of the clamps 28b. The glass support system 24 or the glass carrier plate 25 can be inserted and positioned in the channel-shaped receptacle 30 in a direction perpendicular to the longitudinal extension of the facade profile 21—this also applies to the following embodiments.

[0064] The channel-shaped receptacle 30 is part of the facade profile 21, has a polygonal cross-section, and is open on one side to accommodate the glass carrier plate 25 or the glass support system 24. The channel-shaped receptacle 30 can be filled with an at least temporarily flowing support medium 40, at least in sections, via the channel opening 33. The at least temporarily flowing support medium 40, in the cured state, partially supports the clamping foot 28, the fastening bolts 26, 26a, and a support plate 27 in the channel-shaped receptacle 30. The clamping foot 28 and the support plate 27 penetrate partially into the channel-shaped receptacle 30 of the facade profile 21, with the clamping surfaces 29 being pressed against the channel surface 31 of the channel-shaped receptacle 30.The channel-shaped receptacle 30 on the facade profile 21 can be filled with the previously disclosed at least temporarily flowing support agent 40 during manufacture as well as during final assembly of the facade system 20 - see . Fig. 3.

[0065] In the first embodiment shown, the support means 40 is a temporarily flowing mortar, which is injected with an injection tool 45 during the fastening process between the clamping foot 28, the fastening bolts 26, 26a, a support plate 27, and the channel-shaped receptacle 30. This flowing mortar fills the free space around the contacting surfaces 32 and, after hardening, exhibits a finite strength. The additional volume of the mortar makes the connection more compact and ensures better load distribution around the contacting parts. As a result, the entire connection is relatively stiffer and can withstand heavier loads with relatively less deformation.

[0066] Fig. Figure 4 shows the facade system 20 in its final assembled state, with the glass support system 24 arranged in the facade profile 21, two facade panes 22, 22a arranged on the glass support system 24, and a pressure strip 23 and a cover profile 23a pressing against the facade panes 22, 22a. The glass support system 24 is supported in the facade profile 21 with a hardened mortar as a support means 40.

[0067] Fig. 5 shows a further embodiment of a facade system 120 according to the facade system 20 from the Fig. 1 to Fig. 4, wherein a glass carrier plate 125 is arranged as a fastening element in the channel-shaped receptacle 130 of the facade profile 121. A clamping foot 28, as in Fig. 1 to Fig. 4, can optionally be present. Arranged in the channel-shaped receptacle 130 is an at least temporarily flowing support means 140, which additionally comprises an adhesive component 141. Thus, the support means 140 acts not only as a mechanical support, but also as an adhesive, which creates a material-to-material connection between the glass carrier plate 125 and the channel-shaped receptacle 130. In the cured state, the support means 140 is configured such that it only forms a material-to-material connection with the material of the at least one channel-shaped receptacle 130 and merely supports the glass carrier plate 125. The glass carrier plate 125 has a contact surface 126, which presses against the contact surface 131 of the channel-shaped receptacle 130.

[0068] Fig. 6 shows a further embodiment of a facade system 220 according to the facade system 120 from the Fig. 5, wherein the glass carrier plate 225 has a first and a second contact surface 226, 227, which press against the contact surfaces 231, 232 of the channel-shaped receptacle 230. The support means 240 is designed such that, in the cured state, it forms a materially bonded connection with the channel-shaped receptacle 230 and with the glass carrier plate 225.

[0069] Fig. 7 and Fig. 8 show a further embodiment of a facade system 320 according to the facade system 20 from the Fig. 1 to Fig. 4, wherein a glass carrier plate 325 is arranged as a fastening element in sections in the channel-shaped receptacle 330 of the facade profile 321. A clamping foot 28, as in Fig. 1 to Fig. 4, may be optionally present. A hardened mortar in powder or granular form is present in the channel-shaped receptacle 330 as the support agent 340, which has been processed by mixing with organic or inorganic binders / universal solvents, such as water. The glass carrier plate 325 has an opening 326 in which a screw 327 is arranged, which is screwed through the support agent 340 and into the facade profile 321. The channel-shaped receptacle 330 has non-parallel surfaces 331 and straight surfaces 332 against which the support agent 340 rests.

[0070] Fig. 9 shows a further embodiment of a facade system 420 according to the facade system 320 from the Fig. 7 and Fig. 8, wherein a glass carrier plate 425 is arranged as a fastening element entirely in the channel-shaped receptacle 430 of the facade profile 421 and touches the channel-shaped receptacle 430 at the front. In addition to a first screw 427, which is also screwed through the opening 426, there is a further screw 428 which penetrates the glass carrier plate 425 and the cured support means 440 perpendicular to the opening 426.

[0071] Fig. 10 shows a further embodiment of a facade system 520 according to the facade system 20 from the Fig. 1 to Fig. 4, wherein a glass carrier plate 525 is arranged as a fastening element in sections in the channel-shaped receptacle 530 of the facade profile 521. A clamping foot 28, as in Fig. 1 to Fig. 4, may be optionally present. The glass support plate 525 has three openings 526, wherein the central opening serves as a filling opening 527 for injecting or filling the at least temporarily flowing support agent 540. The two outer openings 526 serve to receive a fastening means, as previously described in Fig. 7 and Fig. 8. The channel-shaped receptacle 530 has limiting elements 550. The limiting elements 550 form a barrier for the at least temporarily flowing support agent 540, preventing it from undesirably spreading along the channel-shaped receptacle 530.

[0072] Fig. 11 shows a further embodiment of a facade system 620 according to the facade system 520 from the Fig. 10, wherein an opening 622 is provided on the facade profile 621, which is designed as a fill level control opening 655, so that the amount of the at least temporarily flowing proppant 640 to be filled can be easily controlled. A ventilation opening 656 is provided, so that the curing of the at least temporarily flowing proppant 640 is improved. The proppant 640 can have a high viscosity, e.g., a Portland cement-based mortar, which has a high consistency and high flow resistance. Such a viscous proppant can be injected into a horizontal or vertical facade profile channel with plastic or metal plugs at the ends in order to fix the proppant 640 before and after the attachment of the glass carrier plate 625. The aforementioned proppant 640 has fibers that do not change their shape and geometry even after moderate cracking in the cured proppant 640.Such a support means can also be used in the other embodiments of the facade system described here.

[0073] Fig. 12 shows a further embodiment of a facade system 720 according to the previously shown facade systems 20, 120, 220, 320, 420, 520, 620, wherein a glass carrier plate 725 with a fastening sleeve 780 for receiving a fastening means 727, such as a screw or a bolt, is provided, wherein the fastening sleeve 780 penetrates at least partially into the at least one channel-shaped receptacle 730. The support means 740, in the cured state, directly supports the fastening sleeve 780, thus improving the rigidity of the facade system 720. The cured support means 740 presses on the fastening sleeve 780, preventing it from being pulled out of the at least one channel-shaped receptacle 730. For this purpose, the fastening sleeve 780 has an external surface structuring 782 so that the connection between the fastening sleeve 780 and the support means 740 is improved in the cured state.The support means 740 adapts to the outer surface structuring 782 in the flowing state, so that a relative movement between the support means 740 in the cured state and the outer surface structuring 782 is prevented due to the interlocking.

[0074] Fig. 13 shows a further embodiment of a facade system 820 according to the facade system 720 from the Fig. 12, wherein a fastening sleeve 880 has an inner surface structuring 883 and an outer surface structuring 882, so that the connection between the glass carrier plate 825 and a fastening means 827 and the support means 840 is improved in the cured state.

[0075] Fig. 14 shows a further embodiment of a facade system 920 according to the facade system 820 from the Fig. 13, wherein a fastening sleeve 980 has a further inner surface structuring 983 and an outer surface structuring 982, so that the connection between the glass carrier plate 925 and a fastening means 927 and the support means 940 is improved in the cured state.

[0076] The previously illustrated fastening sleeves 780, 880, 980 have tribological internal and / or external surface structures, such as grooves, wave-like shapes, rough textures, crater-like depressions, patterns with depressions and elevations, which lead to better contact with the support material 740, 840, 940. The support material 740, 840, 940 can be cement-based, polymer-based resin, or rubber-based, or can comprise fiber-reinforced cement mortars, fiber-reinforced resins, self-curing binders, UV-curing binders, and naturally occurring binders, and can be organic or inorganic.

[0077] Alternatively or additionally, the channel-shaped receptacle may also have tribological internal and / or external surface structures, such as grooves, wave-like shapes, rough textures, crater-shaped depressions, patterns with depressions and elevations, which lead to better contact with the support means 740, 840, 940 and / or with the fastening means 26, 26a, 327, 427, 428, 528, 727, 827, 927, according to the previously shown embodiments.

[0078] Fig. Figure 15 shows a further embodiment of a facade system 1020 with a horizontal facade profile 1021 and a vertical facade profile 1121, wherein the previously shown embodiments of the facade systems 20 to 920 are particularly suitable here. Both facade profiles 1021, 1121 each have a channel-shaped receptacle 1030, 1130 for partially receiving a glass carrier plate 1025 as a fastening element. The channel-shaped receptacle 1030 of the vertical facade profile 1021 extends along the longitudinal extent of the vertical facade profile 1021, and the channel-shaped receptacle 1130 of the horizontal facade profile 1121 extends along the longitudinal extent of the horizontal facade profile 1121. The glass carrier plate 1025 is L-shaped and is a corner connector for connecting the horizontal and vertical facade profiles 1021, 1121.A support means 1040, as previously described in the embodiments, is arranged in the channel-shaped receptacles 1030, 1130.

[0079] Fig. Figure 16 shows channel-shaped receptacles A, B, C, and D of various shapes, including circular, triangular, conical, trapezoidal, open or closed polygonal, partially curved, regular, or irregular geometry with multiple non-parallel surfaces. The at least one channel-shaped receptacle D can consist of only a groove formed by two parallel surfaces. These channel-shaped receptacles A, B, C, and D can each be welded individually to a closed or open facade profile.
