Description

Facade system, assembly process and a glass support system

The present invention relates to a facade system according to the preamble of patent claim 1, an assembly method according to patent claim 11 and a glass support system according to the preamble of patent claim 15.

Technological background

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 façade is designed to support all or part of its own weight and does not provide alternative load paths for a building's structural loads. In addition, facades carry wind loads that act on the building, which include suction forces or pressure forces, but can also carry snow loads. The facade profiles of the facade system support the weight of the filling elements, which are usually transparent, translucent or opaque, with the help of certain fastening elements such as glass support systems or other fastening systems. These fastening elements serve as a flat base for the filling elements and transfer their weight to the facade profile by being subjected to shear and/or tension and/or bending. The fasteners are typically positioned into the profile channel and connected to the facade profile either by screwing, hammering or in some cases welding. In some special configurations, the fastener is docked in the channel and holds itself in place due to its geometric shape, eliminating the need for additional screws, welds, etc.

WO9618778 A1 is known from the prior art. A profile system with thermal break means intended for glazed facades consists of intersecting internal elongated structural profile elements which are provided on their outwardly facing side with a longitudinally extending groove for receiving heads of lugs for closing window panes against the structural profile elements hold. Rubber sealing strips are arranged between the inner structural profile elements and the adjacent window panes. The sealing strips have no interruptions and are designed with a web part mounted in the grooves of the structural profile elements and with a flange part on both sides of the web part, the flange parts resting between the components on both sides of the groove and the adjacent window panes and being pressed together in a sealing manner. KR 2020/0068834 A is known from the prior art. This discloses a mounting structure for a glass beam of a curtain wall in which an insulating material is inserted between an inner frame and the forwardly projecting glass beam 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 together in a knurling process.

The disadvantage of the known solutions is that the thermal insulating materials are inserted prefabricated into the grooves of the facade profiles during the production of the facade systems.

DE 101 44 551 A1 is known from the prior art. This reveals a post and beam framework with fire protection elements for a building. The fire protection elements have a core element which is surrounded by a heat-insulating filling compound and a casing, namely a metal profile. A screw channel is arranged in the core profile. The fire protection element has a cover strip, which is attached to the core profile with a fastening screw. Components can be clamped between the cover strip and the front side of the casing of the fire protection element, with the cover strip pressing on the clampable components when the fastening screw is screwed into the screw channel of the screw channel seated in the filling compound. During assembly of the clampable components, only the fastening screw is screwed into the firmly positioned core profile until a desired clamping force acts on the clampable components.

The disadvantage of the known solution is that the interior of the casing is completely filled with filling compound and completely accommodates the core profile. The filling compound is poured into the cladding during the production of the fire protection elements and only serves as a fire protection compound.

GB 2551 55 13 A is known from the prior art. This reveals a facade system with a metal facade profile and a plastic support. The facade profile has a channel-shaped receptacle for receiving the plastic support in sections, the channel-shaped receptacle extending at least along the longitudinal extent of the facade profile. The plastic support is inserted into the channel-shaped holder. The plastic support has support lips and the channel-shaped receptacle has projections. The channel-shaped receptacle is filled with a foam material that flows at least at times, the foam material completely filling the channel-shaped receptacle in the hardened state. After filling, the foam material expands in the entire channel-shaped receptacle and hardens so that the supporting lips of the plastic support are pressed against the projections in the channel-shaped exception.

The disadvantage of the known solution is that the plastic support must be pulled in, pushed in or inserted along the longitudinal extent of the channel-shaped receptacle. In addition, the entire cavity of the channel-shaped receptacle must be filled with the foam material and a quasi-permanent pressure must act on the plastic support in order to prevent the plastic support from slipping relative to the facade profile.

KR 2014 0015873 A1 is known from the prior art. This discloses a multi-part glass support system for arrangement on a channel-shaped receptacle of a facade profile. There are at least a connecting element, a cover and a support element, the support element serving to receive a cover fastening screw.

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

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

The disadvantage of the known solution is that the connecting element itself is not load-bearing when it is suspended at the bottom of the channel-shaped receptacle of the facade profile. The glass support plate suspended at the top of the façade profile exerts a horizontal pressure force on the connecting element at the top, which stabilizes the glass support system. Vertical loads cannot be absorbed by the connecting element alone.

Presentation of the invention

An 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 transfer behavior for a fastener is improved. In addition, an improved assembly method is to be created, with which in particular the rigidity and load transfer behavior for a fastening element on an existing facade system is improved, and an improved glass support system with improved rigidity and improved load transfer behavior is to be created. This task is solved by the features of the independent patent claims. Advantageous further developments are set out in the figures and in the dependent patent claims.

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 receiving the first fastening element at least in sections or is connected to at least one channel-shaped receptacle for receiving the first fastening element at least in sections, the at least a 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 in sections, with an at least temporarily flowing support means, the support means supporting the first fastening element at least in sections in the hardened state in the at least one channel-shaped receptacle.

The at least one channel-shaped receptacle on the facade profile can be filled with the at least temporarily flowing support agent during production as well as during final assembly of the first fastening element of the facade system, with the at least one channel-shaped receptacle being designed or shaped to hold the temporarily flowing support agent in the liquid state to hold the intended support position locally in the at least one channel-shaped receptacle, so that the support means in the solid, hardened state supports the first fastening element directly or indirectly, thereby increasing the rigidity, the strength and the load distribution behavior in the connection between the at least one channel-shaped receptacle and the first Fastening element in the facade profile is improved. An initially pressureless 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, for example, into the at least one channel-shaped receptacle, for example an injection tool, for example an injection tool, being usable. This makes precise filling possible. This means that the load distribution behavior between load-bearing and load-removing components in the facade system is greatly improved. The support means, which flows at least temporarily, has a finite rigidity and strength in the solid state. The facade system can be a metallic or non-metallic facade profile and include aluminum, steel, wood or plastic. The thick weld seam connections known from the prior art between the facade profiles and the first fastening element can be dispensed with, so that the facade profile has 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. The temporarily flowing support means in the channel-shaped receptacle causes at least a doubling of the nominal load capacity of the first fastening element in the hardened state and, in particular, a doubling of the rigidity in the connection with the first fastening element, so that the load transfer behavior is improved. The maximum deformation of the first fastening element is typically limited, since the first fastening element would otherwise lower under load to such an extent that it would rest on a facade filling element, for example on the lower glazing of the facade. Therefore, in the embodiment according to the invention, an increase in the rigidity in the connection leads to an increase in the usable load capacity in the first fastening element.

Reducing the weld seam thickness on the facade profile not only reduces the manufacturing time and assembly time, but also improves the aesthetics of the facade.

In a preferred embodiment, the at least temporarily flowing support means is arranged on the outside of the facade profile in the at least one channel-shaped receptacle. This means that the inside of the facade profile can, for example, either be filled with a fire protection compound or simply remain empty.

The facade profile can have a regular or irregular cross section. The at least one channel-shaped receptacle can be arcuate in order 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 screwed 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 screwed to the facade profile.

The at least one channel-shaped receptacle can be in the form of a circular, triangular, conical, trapezoidal, open or closed polygonal, partially curved shape, or have a regular geometry with several non-parallel surfaces, or have an irregular geometry. The at least one channel-shaped receptacle can only consist 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 means and the first fastening element. The at least one channel-shaped receptacle can be, for example, a screw channel for receiving a screw. The at least one channel-shaped receptacle preferably has at least one limiting element. The limiting element forms a barrier for the at least temporarily flowing support means, so that it cannot spread undesirably along the channel-shaped receptacle. This means that in the hardened state, the supporting agent only acts in the designated area in the channel-shaped receptacle. The limiting element advantageously consists of an unfoamed or foamed shaped piece, such as LDPE (low-density polyethylene). Such limiting elements are easy to produce and can be easily mounted in the at least one channel-shaped receptacle.

In particular, the first fastening element comprises at least one glass carrier plate. Glass support plates or glass supports are used so that facade filling elements rest on facades and can therefore be attached to the facade. Such fastening elements have a load-bearing effect. As a rule, the facade glass is additionally fixed to the facade with glazing beads or connecting buttons. The aforementioned facade system with a glass support plate as the first fastening element improves the load transfer in the facade system. The horizontal and vertical load transfer and stabilization of inclined and horizontal glazing elements are also improved with the glass support plate. In particular, the first fastening element can 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.

Preferably, the first fastening element can be inserted and positioned into the at least one channel-shaped receptacle in the direction perpendicular to the longitudinal extent of the facade profile. The first fastening element therefore does not have to be retracted, pushed in or inserted along the longitudinal extent of the channel-shaped receptacle, as is known. This enables simple assembly, in particular on a construction site, whereby the first fastening element can be positioned precisely in the at least one channel-shaped receptacle from the outside towards 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 means . Retrofitting existing facade systems with fasteners is simplified.

Preferably, a second fastening element is present, which is inserted and positioned in the at least one channel-shaped receptacle, the support means directly supporting the second fastening element at least in sections in the hardened state. This increases the strength and rigidity in the connection between the at least one channel-shaped receptacle and the first fastening element in the facade system.

The second fastening element preferably accommodates the first fastening element at least in sections. The second fastening element supports the first fastening element, so that there is a further improvement in the rigidity in the facade system. In addition, larger load capacities, for example heavy glazing, can be carried by the fastening elements. For example, the second fastening element is a clamping foot or a sliding block, clamping button or the like, and the first fastening element is a glass support plate or a support plate. The glass carrier plate can be inserted into the clamping foot so that it is received in sections by the clamping foot. The clamping foot enables the glass support plate or the support plate to be supported in terms of area along the edge of the at least one channel-shaped receptacle, so that larger load capacities and rigidities in load transfer are possible.

Preferably, at least one of the two fastening elements has at least one fastening sleeve for receiving a fastener, the fastening sleeve penetrating at least sections into the at least one channel-shaped receptacle. In this case, a fastening sleeve is also a receiving opening for receiving a fastener, for example for a bolt, for a screw or the like. This means that at least one of the two fastening elements can be positioned in the at least one channel-shaped receptacle using a point contact or several point contacts.

In particular, in the hardened state, the support means directly supports the fastening sleeve and/or the fastening means in sections, so that the rigidity and strength in the connection between the at least one channel-shaped receptacle and the fastening sleeve and/or the fastening means in the facade system is improved. The hardened support means presses on the fastening sleeve and/or on the fastening means, so that they cannot be pulled out of the at least one channel-shaped receptacle. This prevents the occurrence of localized plastic zones, so that the rigidity and strength is further improved and the connection becomes more compact overall.

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 means. This means that the support means can be positioned precisely at the support position in the liquid or flowing state. An opening on the facade profile can also be designed as a fill level control opening, so that the amount of support agent that is to be filled and flows at least temporarily can be easily controlled. An opening on the first fastening element can serve to allow the support medium to flow at least temporarily position and at the same time use the opening as a fastening opening for a fastener.

Preferably, at least one of the fastening elements has an external surface structuring, so that the connection between at least one of the fastening elements and the support means is improved in the hardened state. The support means can adapt to the external surface structure in the flowing state, so that a relative movement between the support means in the hardened state and the external surface structure is prevented due to the static friction or positive locking or mechanical locking or toothing that occurs.

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

Alternatively or additionally, at least one fastening sleeve has an inner and/or an outer surface structuring, so that the connection between the fastening sleeve and a fastening means or the support means is improved in the hardened state. When flowing, the support means can adapt to the external surface structure, so that relative movement between the fastening sleeve or the support means in the hardened state is prevented due to the static friction/positive fit that occurs. The internal surface structuring improves the strength between the fastening sleeve and the fastener or fastener.

The fastening elements can have tribological internal and/or external surface structures, such as grooves, wavy 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.

In this case, a fastening element is a component that is supported directly or indirectly by the support means in the hardened state, such as a load-bearing element, such as a glass support plate and/or a clamping foot, a sliding block 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. Preferably, the at least one channel-shaped receptacle has an internal surface structuring, so that the connection between the at least one channel-shaped receptacle and the support means is improved in the hardened state. The supporting means can adapt to the internal surface structuring in the flowing state, so that a relative movement between the supporting means in the hardened state and the internal surface structuring 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-shaped 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.

Preferably, the support means is arranged in the at least one channel-shaped receptacle, wherein the support means can already be present in the hardened state or is present in an intermediate state in that it only develops its full support stability with a time delay. The contact surfaces of the first fastening element, without supporting means, 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 hardened state, the support means causes a surface and/or surface-shaped support contact, so that the rigidity and strength are improved. Furthermore, an increase in the pull-out capacity of the first fastening element in inclined facade profiles can be observed. The support agent can, for example, be a filler without adhesive properties, with the filling volume in the at least one channel-shaped receptacle being increased. The filler should 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 the second fastening element in the facade system.

A preferred support means is an at least temporarily flowing mortar which is injected or introduced during the fastening process between the first fastening element and a cavity in the at least one channel-shaped receptacle. This flowing mortar fills the free space around the touching surfaces and has a finite stiffness and strength after hardening. The additional volume of the mortar makes the joint more compact and provides better load distribution around the parts in contact. As a result, the entire connection behaves relatively stiffer and can withstand heavier loads with relatively less deformation. This is generally an advantage if the manufacturer uses the fastener for infill loads that are close to its final load capacity or deformation limit. The mortar can also act as an enabler of heat flow depending on its thermal properties (density, specific heat and thermal conductivity, microstructure, etc.). Preferred are mortars that provide thermal insulation or high thermal resistance to heat flow, as well as mortars that are fire resistant and flame retardant. The same applies to mortars, which can also be used for sound insulation and/or vibration insulation.

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

The at least temporarily flowing support agent advantageously comprises an adhesive component. The support means, which flows at least at times, thus acts not only as a mechanical support, but also as an adhesive which creates a cohesive connection between the first fastening element and the at least one channel-shaped receptacle. In the hardened 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, ie there is no relative sliding during the injection or later in the final state. The adhesive component can include an adhesion improver, which works particularly well on oiled or powder-coated facade profiles. Alternatively or additionally, the supporting agent comprises a hardening agent, so that the time course from the liquid state to the hardened state is shortened and the assembly or production of the facade system is therefore accelerated. Alternatively or additionally, the proppant comprises a solvent. The solvent causes the support agent to flow for a sufficiently long time so that it can be placed in the at least one channel-shaped receptacle in a precise position on the support surfaces. Typically, the solvent evaporates during the curing process of the proppant. The support means is advantageously designed in such a way that it only forms a cohesive connection with the material of the at least one channel-shaped receptacle and only supports the first fastening element. This means that the first fastening element can still be positioned after assembly. The at least temporarily flowing proppant can have a high viscosity, for example a cement-based mortar, which has a high consistency and a high flow resistance. Such a viscous support agent can be injected into a horizontal or vertical facade profile channel with plastic or metal plugs as limiting elements at the ends in order to fix the at least temporarily flowing support agent before and after attaching the fastening element.

Preferably, the at least temporarily flowing proppant comprises fibers. The fibers can be made from various materials, such as plastic, glass, metal wool, or the like. include and/or have different shapes - for example straight, wavy, cranked. 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 to bridge cracks or carry loads even after moderate cracks have formed in the hardened proppant, so that the improved strength remains.

Preferably, at least one ventilation opening is present, so that the hardening of the at least temporarily flowing proppant is improved. The ventilation opening can be arranged on the first fastening element or on the facade profile and, if necessary, can only be indicated as a marking in order to subsequently open this ventilation opening using a tool if necessary.

Preferably, the facade system comprises a further facade profile, wherein the further facade profile has at least one further channel-shaped receptacle for receiving the first fastening element in sections 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 at least in sections in the channel-shaped Recording of the further facade profile is arranged. This can be used, for example, to produce corner connectors to connect 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 facade profile to the corner connector may be uneven or the load may be concentrated in a specific area. A support means enables better and/or more uniform load transfer and increased stiffness. This means that manufacturing tolerances do not play a critical role in the assembly or functioning of the connection. 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) introducing at least a 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) at least partially filling the at least one channel-shaped receptacle with a temporarily flowing support agent; e) curing the support means to support the at least one first fastening element.

The at least temporarily flowing support means can then spread at least in sections in the at least one channel-shaped receptacle and, in the hardened state, support the first fastening element directly or indirectly 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-removing components in the facade system is greatly improved in such facade systems. The thick weld seam connections known from the prior art between the facade profiles and the first fastening element can be dispensed with, so that the barrel has less material in its entirety and can therefore be built more easily. Reducing the weld seam thickness on the facade profile not only reduces the manufacturing time and assembly time, but also improves the aesthetics of the facade. Furthermore, an increase in the pull-out capacity of the first fastening element in inclined facade profiles can be observed.

The method described here is generally advantageous if the manufacturer uses the fastener for infill loads that are close to its final load capacity. Such a method can also be used when retrofitting existing facades where thicker and heavier infills are required after renovation, maintenance or modernization. Such a procedure can also improve the load-bearing capacity of an incorrectly installed fastener. The proppant can also act as an enabler for heat flow depending on its thermal properties (density, specific heat and thermal conductivity, microstructure, etc.). In particular, the assembly method is used on a previously described facade system.

In particular, before step b), at least one limiting element is inserted into the at least one channel-shaped receptacle. The limiting element prevents undesirable distribution of the at least temporarily flowing support means along the channel-shaped receptacle.

Preferably, the at least one first fastening element is inserted into the channel-shaped receptacle in the direction perpendicular to the longitudinal extent of the facade profile. The first fastening element therefore does not have to be retracted, pushed in or inserted along the longitudinal extent of the channel-shaped receptacle, as is known. This enables simple assembly, with the first fastening element being able to be positioned precisely in the at least one channel-shaped receptacle from the outside towards the support position in the at least one channel-shaped receptacle. Retrofitting existing facade systems is simplified.

Preferably, before step b) or simultaneously with step b), a second fastening element is introduced into the at least one channel-shaped receptacle. The second fastening element can accommodate the first fastening element at least in sections and thus supports the first fastening element, so that there is a further improvement in the rigidity and strength in the facade system. For example, the second fastening element is a clamping foot and the first fastening element is a glass support plate or a support plate. The clamping foot enables surface support of the glass support 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 the direction perpendicular to the longitudinal extent of the facade profile.

A glass support system according to the invention for arranging on a channel-shaped receptacle of a facade profile comprising a glass support plate and a clamping foot, the glass support plate being connectable to the clamping foot. There is a support plate that supports the glass support plate, so that the strength, rigidity and load distribution behavior in the glass support system is improved.

In particular, the support plate penetrates the clamping foot in order to engage at least in sections in a channel-shaped receptacle of a facade profile. The support plate can spread the clamping foot in the area of its contact opening in order to improve the clamping function of the clamping foot. A facade profile is preferably present, with at least the clamping foot and the support plate penetrating in sections 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 means during production as well as during final assembly of the facade system, the channel-shaped receptacle being designed or shaped, the temporarily flowing support means in the liquid state at the intended support position to be held locally so that the support means supports the support plate directly or indirectly in the solid, hardened state, which improves the strength, rigidity and load distribution behavior in the facade profile.

Implementation of the invention

The following embodiments of the facade system, some of which are shown schematically, can be used for various different applications, such as vertical facades, horizontal facades, overhead facade elements, sloping, curved or double-curved facades, glazing, internal partitions, external partitions, public meeting rooms (e.g. stadium facades , airport facades, airport glass canopies, etc.), facades or supporting 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.

1 to 4 show a first embodiment of a facade system 20 made of steel with a facade profile 21 and with a glass support plate 25 as a fastening element, the facade profile 21 having a channel-shaped receptacle 30 for receiving at least sections the glass support plate 25 has. The channel-shaped receptacle 30 extends along the longitudinal extent of the facade profile 21 and the glass support plate 25 can be inserted and positioned into the channel-shaped receptacle 30. The glass support plate 25 is part of a glass support system 24, which includes 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 support plate 25 in the assembled state. The support plate 27 spreads the clamping foot 28 in the area 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 foot 28 has receiving openings 29a in order to receive and guide 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 support plate 25 can be inserted and positioned into the channel-shaped receptacle 30 in the direction perpendicular to the longitudinal extent of the facade profile 21 - this also applies to the following ones Embodiments.

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 support plate 25 or the glass support system 24. The channel-shaped receptacle 30 can be filled with an at least temporarily flowing support means 40, at least in sections via the channel opening 33, the at least temporarily flowing support means 40 in the hardened state in the channel-shaped receptacle 30, the clamping foot 28, the fastening bolts 26, 26a and a support plate 27 in sections supports. The clamping foot 28 and the support plate 27 penetrate in sections into the channel-shaped receptacle 30 of the facade profile 21, with the clamping surfaces 29 being pressed from 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 means 40 during production as well as during final assembly of the facade system 20 - see Fig. 3.

The supporting means 40 in the first embodiment shown is a temporarily flowing mortar, which is injected with an injection tool 45 between the clamping foot 28, the fastening bolts 26, 26a and a support plate 27 and the channel-shaped receptacle 30 during the fastening process. This flowing mortar fills the free space around the touching surfaces 32 and has a finite strength after hardening. The additional volume of the mortar makes the joint more compact and provides better load distribution around the parts in contact. As a result, the entire joint behaves relatively stiffer and can withstand heavier loads with relatively less deformation. 4 shows the facade system 20 in a finally assembled state, the glass support system 24 being arranged in the facade profile 21, two facade glasses 22, 22a being arranged on the glass support system 24 and a pressure strip 23 and a cover profile 23a pressing against the facade glasses 22, 22a.
