Description

field of invention

The present invention relates to a device for holding facade glass, a connection node for connecting such devices, a module for holding facade glass, and a system.

background

Façade glasses are known in principle from the prior art. They are used in commercial buildings and modern residential buildings. Facade glass is used, among other things, to close large openings or to create entire facade surfaces. The facade glass is held by a supporting structure. So-called mullion-transom constructions consisting of vertical mullions and horizontal bars are mostly used. The mullion and transom constructions are only suitable to a limited extent for creating surfaces with different angles of inclination of the facade glasses to each other (e.g. a free-form surface, a honeycomb pattern with a sinusoidal shape, etc.).

In this context, it has now emerged that there is a need to provide an improved supporting structure for facade glazing, and in particular there is a further need to provide a robust and geometrically flexible supporting structure for facade glazing. It is therefore an object of the present invention to provide an improved supporting structure for facade glazing provide, in particular, it is the object of the present invention to provide a supporting structure for facade glass that is as robust and geometrically flexible as possible.

These and other objects that may be mentioned or recognized by a person skilled in the art upon reading the following description are solved by the subject matter of the independent claims. The dependent claims develop the central idea of the present invention in a particularly advantageous manner.

Summary of the Invention

A device according to the invention for receiving facade glass comprises: at least one carrier element; at least one first interface at a first end of the carrier element, the first interface being set up to receive a connection element for connection to a connection node; at least one second interface for receiving a fastener that is set up to receive facade glass; wherein the first interface comprises at least one thread for fastening the connecting element, and wherein the thread is aligned in the longitudinal direction of the carrier element.

The term receptacle is to be understood broadly in the present case and includes elements and assemblies that are set up to store, spatially align and fix other elements. The term carrier element is to be understood broadly here and means mechanical construction elements that are set up to absorb loads (e.g. weight load of the facade glass, environmental loads (wind, vibrations)) and to be connected to other carrier elements to form a structure. In the present case, the supporting structure serves to accommodate facade glass. The carrier element can consist of a metallic material. For example, the carrier element consists of aluminum, construction steel, an alloy, a metal with a coating (for example to prevent corrosion). The carrier element is, for example, a hollow profile with a square, rectangular, round, oval or polygonal cross section. The carrier element can be a solid body, for example. The carrier element can be, for example, a hollow body with internal ribs, struts, or foam for reinforcement. The carrier element can be a composite body made of different materials, for example. The carrier element preferably has a constant cross-section over its length. The carrier element preferably has both End faces each have an interface for receiving a respective connecting element. The carrier element is produced, for example, by extrusion, cold forming, welding or gluing. For example, the base body is extruded down to the ends and the interfaces for accommodating the connecting elements are integrated into the carrier material by welding. In the present case, the term interface is to be understood broadly and means an area that is set up to accommodate a mechanical component (eg a connecting element). The interface can accommodate the mechanical component in a force-fitting, form-fitting, force-fitting and form-fitting manner, as well as materially. For example, a force-fit connection takes place via a press fit, a form-fit connection via a dovetail connection, a force-fit and form-fit connection via a screw connection, a riveting process, pinning, a material-locking connection via gluing, welding, etc. The term connection element is to be understood broadly in the present case and includes mechanical elements that are set up to create a mechanical connection between a carrier element and a connection node. The connecting element can be connected to the connection node and/or the carrier element in a form-fitting, material-fitting, force-fitting, form-fitting and force-fitting manner. For example, the connecting element is connected to the connecting node via a press fit, a dovetail connection, a screw connection, a riveting process, a pinning operation, a welding operation, or an adhesive bond. The connecting element can, for example, be connected to the carrier element via the interface of the carrier element in a form-fitting, material-bonding, non-positive manner, or in a form-fitting and non-positive manner. The term connection node is to be understood broadly in the present case and means a mechanical element that is set up to mechanically connect two or more carrier elements to one another. The connection node is used to transmit power from one carrier element to the next carrier element. The connection node has, for example, two or more interfaces that are set up to be connected to two or more connection elements in order to create a connection between two or more carrier elements. The term fastening means is to be understood broadly in the present case and means a means that is set up to fix or fasten and align a facade glass. For example, the fastening means is a clamping device, a bearing with an associated adhesive layer for fixing the facade glass, a lever. The fastening means can, for example, accommodate two facade glass elements. The fastener can, for example, the facade glass at a certain angle, so-called angle of inclination, for Align support element. The fastening means can, for example, when two façade glasses converge on the carrier element, align one façade glass at a first angle to a carrier element and align a second façade glass at a second angle to the carrier element, with the first angle and the second angle being different.

The invention is based on the finding that conventional mullion-transom constructions for accommodating facade glass do not allow any shapes (e.g. free forms or sinusoidal honeycomb shapes), but only flat facades in which the vertical mullions and horizontal bars are arranged perpendicular to one another or only at an angle to one another 0 to 45° inclined mullions and transoms. The connection between the mullion and transom is then usually made using transom connectors. The transom connectors include, for example, two corresponding rail elements that engage in one another and thus form a form-fitting connection via the undercut and, if necessary, are additionally connected in a force-fitting manner with a bracing screw. The first rail element is attached to the transom on the end face in the longitudinal direction. The second rail element is attached to the lateral surface of the post perpendicular to the longitudinal direction of the post. This principle means that only essentially level cross joints or T-joints can be implemented in mullion-transom constructions or joints with. A contact joint in which the bars run in one plane at an angle other than 90° to the contact joint cannot be realized with conventional bars to a limited extent, since neither the bar connectors nor the bars are suitable for this. The same applies to mullion-transom connections in which the transoms do not run parallel to the plane that a mullion spans (usually only one plane) to the transom. The vertical posts serve to transfer the load or absorb the forces, but the horizontal bars do not.

The device according to the invention solves this problem by providing a carrier element that can be used universally. The carrier element has at least one interface with a thread that extends in the longitudinal direction of the carrier element. By arranging the thread in the longitudinal direction, the force can advantageously be better introduced into the carrier element compared to a thread arranged orthogonally to the longitudinal direction of the carrier element. The connection implemented in this way advantageously withstands higher loads. By screwing using several screws of the connecting element with the carrier element, a standardized and load-bearing connection in all directions can be made possible with a connection node. This means that there is no longer a need to differentiate between mullions and transoms, since supposedly horizontally arranged support elements can also absorb loads. The creation of any shape of the glass facade then only requires the adjustment of the connection node, in particular the number of interfaces for receiving the connection elements and their arrangement (translational position and spatial orientation) on the connection node. Because there is no need to differentiate between load-bearing and non-load-bearing support elements, they can advantageously be arranged at any desired angles or alignments with respect to one another. For example, angles between the carrier elements between −10° and +55° in one plane and/or outside the plane are possible with the present invention. Overall, the device is characterized by increased geometric design freedom of the supporting structure, increased load-bearing capacity of the supporting structure and the omission of non-load-bearing crossbars. Furthermore, due to the standardization of the interfaces of the carrier elements, a cost-effective, efficient manufacture of the carrier elements can be made possible.

The thread is preferably arranged in the interior of the carrier element in a solid material area. Due to the arrangement of the thread in the solid material area of the carrier element, higher loads can advantageously be absorbed. The solid material area can be inserted into the carrier element, for example by welding, gluing, press fitting, or pinning. Alternatively, a threaded bushing can also be arranged in the carrier element, for example using one of the joining methods mentioned above. For example, four threads are arranged in the solid material. The solid material can be made of the same material as the carrier element, for example made of mild steel or aluminum. The solid material can, for example, consist of a different material than the carrier element itself. For example, solid material can consist of tool steel and the carrier element can consist of structural steel. The thread is an internal thread. Diameter and pitch can be varied according to the application. Preferably, the diameter and pitch are selected to default to the maximum allowable load of the device with a safety margin. For example, the thread is an M12 thread. The carrier element preferably comprises four threads per end face for receiving a connecting element. The threads are formed, for example, in the solid material by means of a tap, by screw drilling, by thread forming or created by circular milling. For example, the carrier element is designed as a hollow profile and is produced by extrusion, with the solid material region extending over the entire length of the carrier element. For example, the threads are distributed at equal intervals over the circumference of the cross section of the carrier profile.

The carrier element is preferably a hollow profile. The hollow profile has, for example, a rectangular, square, round, oval or polygonal cross section. The hollow profile has, for example, a rectangular cross-section with dimensions of 50mm and 60mm and consists of rolled strip steel that was subsequently formed into a rectangle and welded. The hollow profile can also be produced, for example, by means of extrusion and a corresponding die. The wall thickness of the hollow profile is in the range of 1 to 4 mm, for example. The hollow profile can have any length. The hollow profile consists, for example, of one of the following materials: aluminium, aluminum EN AW 6060 T, steel 235, steel 355 or mild steel.

The device preferably also comprises a first receptacle and a second receptacle, which are each set up to receive a seal, with the first receptacle and the second receptacle being arranged on the carrier element in the longitudinal direction. The first and second receptacles can each be a groove, for example, into which the seal is inserted, pressed or glued. The groove can have an undercut, for example, such that a corresponding seal with a corresponding geometric cross-section leads to a form-fitting and/or force-fitting connection when it is placed in the groove. When inserting, the seal would first be elastically deformed or compressed and relieved again after reaching the end position, so that there is a positive and/or non-positive connection between the receptacle (ie groove with undercut here) and the seal. The seal serves to seal between the carrier element and the facade glass. The seal consists of a silicone or EPDM, which preferably meets the requirements for UV resistance, tear resistance, notch resistance and temperature fluctuations. Furthermore, the seal is preferably compatible with the facade glass. The seal is compressed when the facade glass is installed, which creates the sealing effect between the facade glass and the supporting element. Due to the deformability of the seal, a large number of different angles of the facade glass to the supporting elements can advantageously be realized with the same seal. All you need to do is use the fasteners for the facade glass can be exchanged accordingly. Through the first and second receptacles, two facade glasses that converge on a carrier element can advantageously be sealed towards the inside in a simplified manner. The seals are preferably arranged continuously over the connection node of a first support element in a further support element. The connecting node then has a receptacle for the seal, with the receptacle at the ends of the connecting node opposite the receptacle of the carrier element, preferably touching, so that there is a continuous receptacle from the carrier element to the connecting element. This has an advantageous effect on the sealing of the device.

Preferably, the first receptacle is at an acute angle to the second interface; and the second socket is disposed at the second interface at the acute angle opposite the first socket. By choosing an acute angle between the first receptacle and the second interface and between the second receptacle and the second interface, i.e. an angle between 0° and 90°, a large number of angles of inclination between the facade glass and the carrier element can advantageously be made possible when using the same geometry of a seal.

Preferably the acute angle is 45° or is an average angle between certain glass panes of a free-form construction, the average angle being between -10° and +55°.

The second interface is preferably also set up to accommodate a thermal insulator. The thermal insulator advantageously increases the U-value of the facade glass. The thermal insulator consists, for example, of a plastic, preferably PLA or ABS. The thermal insulator can be constructed in one or more parts. The thermal insulator can be arranged on the fastening means for receiving the facade glass. The thermal insulator is set up to prevent temperature equalization at the second interface to the environment. The thermal insulator can, for example, reduce the thermal conduction due to its material and also the thermal convection due to its geometric shape. The geometric shape of the thermal insulator is designed, for example, in such a way that it prevents air circulation between the spaces between the two or more layers of facade glass. The thermal insulator is, for example, designed geometrically so that it allows air exchange between the Gaps in a multi-layer facade glass are prevented. The thermal insulator has, for example, a branch-shaped structure or a V-shaped structure which extends over the length of the support element. The thermal insulator is connected, for example, via a plug connection, an adhesive connection, a press fit to the second interface or the fastening means for receiving the facade glass. The second interface has, for example, a groove with or without an undercut for mounting the thermal insulator.

The carrier element preferably has a water drainage channel. Due to temperature differences and naturally occurring humidity, condensation can form on single-layer, double-layer or triple-layer facade glass. The condensate can lead to the formation of harmful cultures and must therefore be removed. The condensate formed is advantageously transported out of the glass facade or the device for receiving the facade glass via the water drainage channel integrated into the carrier element. In this way, the humidity in the device for holding facade glass can be regulated with passive elements, ie without additional ventilation or heating. The water drainage channel is, for example, a continuous groove which extends along the upper side of the carrier element and drains the condensate out of the device at a removal point. The water drainage channel can be arranged, for example, between the seat for the seal and the second interface for receiving the fastener. The water drainage channel can, for example, have a closed, hollow-cylindrical contour that allows condensate to flow in from the facade glass at one or more points and allows the condensate to drain off from the device at one or more points. The water drainage channel is arranged, for example, between the seat of the seal and the thread and extends essentially over the length of the carrier element. The water drainage channel has, for example, a circular cross section, a triangular cross section, a polygonal cross section. The water drainage channel is produced, for example, by means of extrusion and a corresponding element in the die directly during the production of the carrier element. The water drainage channel can be set up, for example, in order to be continuously connected to a further water drainage channel of a further carrier element via the connection node. As a result, a large, multi-part facade glass construction can be efficiently drained, since then only on a few Points of individual carrier elements of a supporting structure for the facade glass water must be removed and not at all carrier elements.

The carrier element is preferably made of aluminum. Aluminum is characterized by its low density compared to steel, with otherwise good mechanical properties such as a high modulus of elasticity and high tensile strength. This can have an advantageous effect on the geometric design freedom, since lower dead loads act on the structure. For example, the carrier element also includes composite materials, for example fiber-reinforced composite materials. For example, the carrier element consists of wood.

A further aspect relates to a connecting node for connecting devices for holding facade glass, comprising: a base body; at least one first interface, which is set up to receive a first connection element for connection to a first device described in more detail above; at least one second interface, which is set up to receive a second connection element for connection to a second device described in more detail above; wherein the first interface and the second interface are arranged on the base body; at least one water drainage channel; at least one receptacle configured to receive a seal; wherein the water drainage channel and the socket are additively manufactured on the base body in order to enable a continuous transition of the water drainage channel and the socket to the corresponding water drainage channels and sockets of the first and second device. To create complex free-form glass facades, the connection nodes that align two or more support elements with each other are indispensable. Through the connection node, support elements are arranged and loads are transferred from one support element to the other. The connection node also serves to arrange seals and to provide a water drainage channel. Both are important functional requirements for large, complex glass facades. When using essentially standardized devices described in more detail above, the generation of any free-form surfaces requires the specific setting of the free-form surface via the connecting nodes, which differ only in their lengthwise extent. A promising option that offers complete freedom of design for this is the additive manufacturing of the complete connection node. However, this possibility is characterized by increased production costs. Through hybrid manufacturing, ie Conventional processes such as machining or casting, in conjunction with additive manufacturing processes, the manufacturing costs can be advantageously reduced. This is made possible by the definition of one or more base bodies, which allow a large range of different angles when arranging the two or more devices for holding facade glass relative to one another. The base body is produced, for example, by archetypes (e.g. casting process, aluminum die-casting) or by a machining production process (e.g. milling). The interfaces for accommodating the interfaces for accommodating the connecting element can be produced, for example, by likewise machining from the base body or by additive manufacturing. For example, the additive manufacturing process is Selective Laser Sintering (SLS), Electron Beam Melting (EBM), Direct Metal Laser Sintering (DMLS) or Selective Laser Melting (SLM). The material of the base body preferably corresponds to the material of the additively produced interfaces for receiving the connecting elements, since these have to carry the load. The additive manufacturing of the water drainage channel and the seat of the seal can be made of the same material as that of the base body or a different material. By choosing a different material, costs can be reduced, for example, since there are no special strength requirements for the water drainage duct and for receiving the seal. For example, the material properties of the same material (e.g. aluminum) in the additively manufactured areas for the drainage channel, seat for the seal and interface for the connecting element can be varied according to the mechanical requirements. For example, the maximum density can be created in the interface for the connector, a moderate density for the seal housing and the water drainage channel. It should be pointed out at this point that the density correlates with the mechanical properties such as tensile strength, and this can be specifically adjusted in additive manufacturing processes. The hybrid production of the connecting node allows the advantages of mass production to be used for the base body and the advantages of individualization for accommodating the seal, drainage channel and, if appropriate, interfaces for the connecting element. This enables a cost-effective, sustainable, flexible production of connection nodes with any geometry. The hybrid production also enables an optimization of the connection element to the load paths of the supporting structure for accommodating the facade glass. This optimization of the connection node requires a mathematical load path calculation, which is part of a topology optimization of the component CAD programs can be carried out. For example, the connection node is roughly pre-modeled, the desired angles of the support elements to be connected are specified, and loads and load directions are entered. From this, for example, the topology optimization algorithm determines the necessary material distribution for the connection node. From this, for example, an STL file or a STEP file is derived, which can be used for conventional production and additively to generate a control program for the production machine. For example, there are hybrid milling machining centers that are equipped with a build-up welding unit and can produce both by cutting and by additive manufacturing.

A further aspect relates to a module for accommodating facade glass, comprising: at least one device described in more detail above; at least a first seal and a second seal; at least one fastener configured to accommodate facade glass; at least one thermal isolator; at least a facade glass. The following steps, for example, are carried out as part of the assembly: First, a device described in more detail above is equipped with a first and a second seal. For this purpose, the seal, for example an elongate EPDM seal, is pressed into a receptacle, for example a groove, of the device, as a result of which a non-positive connection is established. In the next step, a fastener, for example a lever element, is screwed into the second interface of the carrier element in a pre-assembly position and a thermal insulator is also clicked into the second interface of the carrier element. A facade glass, for example a two-layer facade glass with a mounting pocket, is then arranged on the lever element, the lever element being brought into engagement with the mounting pocket of the glass facade. The lever element is then turned or screwed into the end position, which causes a clamping effect between the lever element and the facade glass. This clamping effect is used to fix the facade glass to the device for receiving facade glass. For example, several fasteners can be attached at regular or irregular intervals in the case of larger dimensions of facade glass. The fastening means is designed, for example, to accommodate two opposing facade glasses. For example, the fastening means is designed with two lever elements, each lever element being able to hold a facade glass and the lever elements being aligned in opposite directions. The fastening means can be a fastening strap or a fastening hook, for example. The fastener can For example, a two-sided clamping device (base plate and counter plate) that clamps a facade glass in between using a quick-release fastener or screw connection.

The fastening means is preferably set up in order to enable different angles of inclination when the facade glass is being accommodated. In the present case, the term angle of inclination means the angle between the carrier element and the facade glass, with the carrier element accommodating the facade glass. The different angles of attack can be realized, for example, by different embodiments of a fastening means. For example, there are fastening means for specific angles of attack that only allow this one angle of attack. For example, there are fasteners that allow multiple angles gradually or continuously adjustable. For example, the mounting point of the fastener for the glass facade can be pivoted (e.g. using a hinge with a lock). For example, the mounting point of the fastener is height-adjustable (e.g. screw connection with lever element). This can have an advantageous effect on the geometric design freedom.

The façade glass is preferably in one, two or three layers. The facade glass can have any shape, size and thickness. The facade glass preferably has a rectangular surface, a triangular surface and/or a polygonal surface. The facade glass can achieve a better U-value through a large number of layers. This can have a beneficial effect on the insulation of the glass facade.

Another aspect relates to a system, comprising: at least a first and a second module described in more detail above; at least one connection node for connecting devices for holding facade glass. The connecting node can be manufactured conventionally, ie using archetypes, subtractive manufacturing processes, or additive manufacturing processes, or a combination thereof. The system is assembled as follows, for example. First, a first preassembled module is connected to the connection node, then a second preassembled module to the connection node. The connection between the first module and connection node is made, for example, via the corresponding connection elements (eg a snap-in connection, preferably a dovetail snap-in connection) attached to the module and connection node. Thereafter, a first seal in a recording in the first module, the connection node, the second module arranged by plugging. The water drainage duct of the first module is connected to the water drainage duct of the second module via the connection node, which also contains a water drainage duct. The facade glass is then arranged in the fastening means of the individual modules that have been brought together. By assembling a large number of modules, which are connected to one another via connecting nodes, a glass façade is created that can be scaled as required.

The connection node of the system is preferably a connection node described in more detail above.

figure 1 shows a detail of a device 10 for receiving facade glass of a first embodiment. The device 10 comprises a carrier element 11. The carrier element 11 is shown in a plan view. The carrier element 11 is a hollow body with a rectangular cross section. The carrier element 11 consists of aluminum. In the present case, the carrier element 11 has been produced using an extrusion process. The carrier element 11 comprises a first interface 12 at a first end of the carrier element 11, which is set up as a connection element (cf figure 9 ) to connect to a connection node (cf figure 14 ) record. In the present case, the first interface 12 comprises four threads 13, 14, 15 and 16. The connection node is connected to the carrier element 11 via a screw connection. The four threads 13, 14, 15 and 16 are arranged at the respective corners of the carrier element 11. The four threads 13, 14, 15 and 16 run parallel in the longitudinal direction of the carrier element 11. The four threads 13, 14, 15 and 16 are each arranged in a solid material area 17, 18, 19 and 20. The main body of the four threads 13, 14, 15 and 16 is also produced, for example, by the extrusion process. This means that the die that is used in the pressing process is used to produce both the hollow profile of the carrier element and the base body of the thread. In a further step, a thread is then cut into the base body using a tap. Alternatively, the carrier element can also consist of an extruded main area without a base body for threads (ie solid material area) and, for example, welded-on end areas that contain the four threads. The solid material area can be inserted into the carrier element as an alternative to extrusion, for example by welding, gluing, press fitting, or pinning. Alternatively, a threaded bushing can also be arranged in the carrier element 11, for example by one of the joining methods mentioned above. Diameter and pitch can be varied according to the application. Preferably, the diameter and pitch are selected according to the maximum allowable load of the device with a safety margin. For example, the thread is an M12 thread. The carrier element 11 also includes a second interface 21 for receiving a fastener (cf figure 7 ), which is set up to protect facade glass (cf. on this figure 10 ) record. In the present case, the second interface 21 is designed as a screw connection in the form of an external thread onto which the fastening means (eg a clamping device) is screwed. Alternatively, the second interface 21 could also have a plug connection, interference fit, or a clamp connection pick up fasteners. The second interface 21 can, for example, be subsequently welded to the extruded carrier element or produced directly during the extrusion process (eg with a plug-in connection). For example, only the base body of the second interface can be produced in the extrusion process and, for example, a thread can be cut into the base body in a subsequent processing step. The second interface 21 can, for example, extend over the entire length of the carrier element 11 or only be at the ends, or arranged at regular intervals. In the present case, the second interface 21 is arranged at regular intervals over the carrier element 11 . Furthermore, the device 10 comprises a first receptacle 22 and a second receptacle 23, which are each set up with a seal (cf figure 6 ) record, wherein the first receptacle 22 and the second receptacle 23 are arranged on the support member 11 in the longitudinal direction. The seal serves to seal between the carrier element 11 and the facade glass (cf figure 10 ). In the present case, the first receptacle 22 and the second receptacle 23 are each a continuous groove that is produced directly via the extrusion process. In the present case, the receptacles 22 and 23 have an undercut such that a corresponding seal (cf figure 6 ) with a corresponding geometric cross-section when inserted into the groove leads to a form-fitting and, if necessary, force-fitting connection. In the present case, the first receptacle 22 and the second receptacle 23 are arranged at an acute angle to one another in relation to the first interface 21 . The acute angle is 45°. By choosing an acute angle between the first receptacle 22 and the first interface 21 and between the second receptacle 23 and the first interface 21, i.e. an angle between 0° and 90°, a large number of angles between the facade glass and the carrier element 11 make possible. In the present case, the second interface 21 is also set up to form a thermal insulator (cf figure 4 ) record. The receptacles 22 and 23 are further adapted to be engaged with the connection node such that the seals can be continuously placed from one support member through the connection node to the next support member. In the present case, the device 10 further comprises two water drainage channels 24 and 25 which are arranged on the carrier element 11 . In the present case, the water drainage channels 24 and 25 have been produced directly via the extrusion process. The water drainage channels 24 and 25 are used to remove condensate that forms on the surface of the facade glass, for example as a result of temperature differences. The water drainage channels 24 and 25 point at certain points Removal points in the carrier element 11 (eg through hole), through which the condensate of the device 10 can be removed. This prevents, for example, fogging of the facade glass or mold formation due to moisture. The water drainage channels 24 and 25 are set up in the present case in order to be able to flow via the connection node (cf figure 14 ) to be continuously connected to a further water drainage channel of a further carrier element. As a result, a large area of a large number of individual facade glasses can advantageously be drained efficiently, since water then only has to be removed from a few points of individual support elements of a supporting structure or composite and not from all support elements.

figure 2 shows a detail of a device 30 for receiving facade glass of a second embodiment. The description of the embodiment in figure 2 is limited to the differences to the in figure 1 embodiment shown. In contrast to the in figure 1 Device 10 shown, the device 30 has a carrier element 31 with a round cross section. The carrier element 31 was also produced from aluminum by extrusion. The first interface 35 for receiving the connection element for connection to the connection node has three threads 32, 33 and 34 in the present case. The threads 32, 33 and 34 are distributed over the circumference of the round cross section of the carrier element 31 at 120° intervals from one another. The threads 32, 33 and 34 are arranged in parallel in the longitudinal direction of the carrier element 31 in solid material. The threads 32, 33 and 34 have been produced in two stages. First, the base body of the thread was produced using the extrusion process and then the threads were cut into the base body using tapping. In contrast to the embodiment in FIG figure 1 a second interface 36 for receiving a fastener, which is designed as an internal thread. The second interface 36 could also be designed identically to the interface 21 . A clamping device, for example, is screwed into the internal thread of the second interface 36 as a fastening means.

figure 3 shows a detail of a device 40 for receiving facade glass of a third embodiment. The description of the embodiment in figure 3 is limited to the differences to the in Figure 1 and 2 embodiments shown. In contrast to the in Figure 1 and 2 embodiments shown, the support member 41 a semi-arch shape. In the present case, the carrier element 41 is set up in order to be brought into engagement with a further carrier structure 42, in this case a tube made of steel. The carrier element 41 functions here as a so-called attachment profile. The intervention takes place, for example, via gluing, welding, a snap connection and/or fastening pins.

figure 4 one shows a selection of thermal isolators. The thermal insulator serves to increase the U-value. The thermal insulator can, for example, reduce the thermal conduction due to its material and also the thermal convection due to its geometric shape. The geometric shape of the thermal insulator is designed, for example, in such a way that it prevents air circulation between the spaces between the two or more layers of facade glass. In the present case, the thermal insulator is designed in several parts. It consists of a base body to which the thermal insulation body is attached. The base body 50 and 51 differ in size. The base bodies 50 and 51 each have a connection point 54, 55, which is set up with the second interface of the carrier element (cf figure 10 ) to be engaged. The connection points 54 55 are snap-in connections in the present case. However, the connection points can also be designed as screw connections, for example internal or external threads. The base bodies 50 and 51 consist of PLA or ABS, for example. In the present case, the base bodies 50 and 51 each have a second connection point 56 and 57 for mounting a second base body 53 . The second base body 53 also has a second connection point 63 for fastening a seal (cf figure 5 ) on. The second connection point 56 and 57 is a plug connection in the present case. The thermal insulator 64 has a base body 52 onto which a thermal insulation body 58 is mounted by sliding. In the present case, the thermal insulation body 58 consists of ABS. The thermal insulation body 58 has a branch-like structure, each with two branches that are set up to reach into gaps in the facade glass in order to prevent air circulation. The thermal insulator 60 comprises a two-part base body comprising the base bodies 61 and 62, which are connected to one another via a plug connection. The thermal insulator 60 further comprises a thermal insulation body 59 which is arranged over the base bodies 61 and 62 . In the present case, the thermal insulation body 59 has three branches compared to the thermal insulation body 58 .

figure 5 Figure 12 shows exemplary gaskets of one embodiment configured to be attached to the body of the thermal isolators. The seals 70, 71 and 72 in this case consist of EPDM and differ from one another in terms of their size. The seals 70, 71 and 72 each have an interface area 73, 74 and 75 which is designed to be brought into engagement with the second connection point 56, 57 of the first base body or the second connection point 63 of the second base body via a force-fitting and form-fitting connection will. The seals 70, 71 and 72 are used to seal two adjacent glass façade areas (cf. figure 10 ) and the prevention of air circulation.

figure 6 Figure 8 shows a seal 80 of one embodiment. In the present case, the seal 80 consists of PLA, EPDM or silicone. The seal 80 has a complex corrugated arcuate cross-sectional surface 85 with an interface 81 adapted to be engaged with one of the first receptacle and the one second receptacle of a support member (see FIG figure 1 and figure 10 ). The seal 80 also has cavities 82, 83 and 84 which allow compression of the seal. The corrugated arcuate cross-sectional area 85 is designed to be used as a seal for any inclination angle of the facade glass. This is achieved by the arcuate cross-sectional area 85 and the cavities 82, 83 and 84, which are correspondingly deformed when they come into contact with the carrier element and the facade glass and thus rests sealingly, regardless of the angle of inclination.

figure 7 shows six different fasteners 90, 91, 92, 93, 94 and 95, which are set up to fasten a facade glass (cf figure 10 ) to hold or fix. The fasteners 90, 91, 92, 93, 94 and 95 are made of aluminum with increased strength. In the present case, the fastening means 90, 91, 92, 93, 94 and 95 have the same basic structure and differ only in the dimensioning of the individual areas. The fastening means 90 is described below as representative of the fastening means 91 to 95 . The fastening means 90 has a receptacle 96 which is designed to be connected to a second interface of a carrier element (cf figure 10 ). The receptacle 96 is, for example, a snap-in connection in the present case, which is attached to the corresponding counterpart of the second interface of the carrier element (cf figure 10 ) is inserted. The fastener 90 further includes a centerbody 98 characterized by the centerbody height. The fastening body 90 further comprises a lever element 97 which is set up to clamp the facade glass. The lever element 97 is defined by a lever length and characterizes the inclination of the lever. Furthermore, in the lever element 97 there is an interface 99 for receiving a seal, for example the one in figure 5 described seal arranged. The levers 90 to 95 differ only in the middle body height, lever length and lever inclination, in such a way that different angles of inclination of the facade glass can be made possible. For example, fasteners 90 and 93 allow an angle of attack between -10° and 10°, fasteners 91 and 94 allow an angle of attack between 10° and 20°, and fasteners 92 and 95 allow an angle of attack between 30° and 50°.

figure 8 12 shows a plan view of a glass carrier 100 which is set up to accommodate three-layer facade glass and a glass carrier 101 which is set up to accommodate two-layer facade glass. The glass supports 100 and 101 are designed in such a way that they can bear the weight of the facade glass. The glass carriers 100 and 101 each have a base body 104 and 105 . In the present case, the base bodies 104 and 105 are made of aluminum, preferably extruded. The glass supports 100 and 101 each have a shaped cushion 102 and 103, each of which is defined for a specific angle of inclination of the facade glass relative to the support element. The facade glass is arranged on one or more mold cushions. Molded pads 102 and 103 are made of EPDM or plastic. The shaped pads are milled or deflected from a profile.
