FACADE CONSTRUCTION AND METHOD FOR ASSEMBLING A FACADE CONSTRUCTION

Description

[0001] The present invention relates to a facade construction with two vertical mullion profiles, on each of which at least one protruding transom connector is fixed on the facing side, and a transom profile which is held on opposite sides on each of the transom connectors, wherein the transom profile is designed as an open hollow profile which is pushed onto the transom connectors, wherein the transom profile is pushed onto the transom connectors in a horizontal direction and the transom profile is butted at the end sides and has a flat end face, and a method for assembling a facade construction.

[0002] US Patent 3,266,210 discloses a facade construction in which glass panes can be installed between mullion and transom profiles by inserting them into a groove at their edges and then pivoting them. The transoms of the mullion-transom construction are machined at their ends to engage with a groove in the mullion profiles. This type of machining and assembly of the transom profiles is complex, even though the subsequent installation of the glass panes is highly efficient.

[0003] EP 3 464 748 B1 discloses a facade wall in which the transom profiles are provided with a milled contour at their ends so that the transom profiles are first positioned and pivoted between two mullion profiles, and then fixed by a further rotational movement around the longitudinal axis. Here, too, the machining of the transom profiles at their ends is comparatively complex, and jamming can occur during assembly. BE 1006822A7 also discloses a facade construction in which the transom profiles are formed with a stepped profile at their ends by milling, so that they can then be mounted at their ends in a recess on a mullion.

[0004] KR 101 353 351 B1 discloses a post-and-beam construction made of T-shaped profiles in cross-section. Beam connectors are fixed to the posts, onto which the beams are then slid from the inside. This creates a frame on the outside formed by inwardly projecting webs. A similar construction is also shown in KR 10 2011 0011154, in which cuboid hollow profiles are used instead of T-shaped profiles, with the beam profiles being provided with a slot-shaped recess for sliding onto a beam connector.

[0005] US 2022 / 0290430 A1 discloses a facade construction in which recesses are provided in the mullions into which a mullion connector mounted on a mullion profile is inserted.

[0006] It is therefore an object of the present invention to provide a facade construction and a method for assembling a facade construction which enables effective assembly of a transom profile to two post profiles.

[0007] This problem is solved by a facade construction having the features of claim 1 and a method having the features of claim 11.

[0008] In the facade construction according to the invention, a transom profile is held on opposite sides by a transom connector on a vertical mullion profile, wherein the transom profile is designed as an open hollow profile that is slid onto the transom connectors. This allows the transom profile to be mounted and fixed onto the transom connectors by a simple sliding motion, which simplifies assembly and ensures stable support of the transom profile. In the assembled position, the transom connectors are each arranged in a hollow chamber of the transom profile.

[0009] According to the invention, the transom profile is slid onto the transom connectors in a horizontal direction. The transom profile is slid onto the transom connectors from an outer side, relative to the facade construction. Due to the horizontal sliding movement, the transom profile is butted at the ends, resulting in a flat end face, thus avoiding time-consuming milling work.

[0010] For stable support, the transom profile can have a plate-shaped hollow chamber, bounded on both the top and bottom by a profile wall. The hollow chamber can have a height of between 5 mm and 50 mm, particularly between 8 mm and 30 mm, to enable stable support with a narrow visible width. The transom profile can be fixed to the transom connector using fasteners such as screws. The transom connector can be made of metal or plastic and is also screwed to the post profile or fixed by other fasteners.

[0011] In a preferred embodiment of the facade construction, an insulating glass unit is arranged between two mullion profiles and two transom profiles, and is clamped in place using glazing beads. The glazing beads are preferably located on an inner side of the facade construction, which simplifies assembly. In the assembled position, the glazing beads are preferably flush with the inner or outer surface of the mullion or transom profile.

[0012] The mullion profiles can incorporate a protruding retaining strip to support the insulating glass unit. This protruding retaining strip covers an edge of the insulating glass unit, for example with an integrated seal, to clamp the unit in place. Additional retaining strips can be provided on the mullion profiles, so that the insulating glass unit is directly supported on one outer side by the retaining strips on the mullion and transom profiles.

[0013] Preferably, the open hollow chamber of the bar profile is closed via a cover profile, so that the bar profile is visually appealing and the unit consisting of bar profile and cover profile can be easily cleaned.

[0014] The transom profile is preferably formed, at least partially, from an extruded profile that is cut vertically to the required length. The transom profile can have at least one insulating web, for example made of plastic, arranged between two metal profiles. Such multi-part transom profiles can be easily prefabricated and cut to the desired length, depending on the distance between the two mullion profiles. The mullion profile can also be designed with two metal profile sections for high thermal insulation, with at least one insulating web between them.

[0015] The mullion profile preferably has a groove for inserting an edge of an insulating glass unit. This allows the insulating glass unit to be installed using a "shuffle" method, by first inserting an edge of the insulating glass unit into the groove and then pivoting it so that the insulating glass unit can then be moved and received in the groove on opposite sides.

[0016] In the inventive method for assembling a facade structure, two vertical mullion profiles are first erected, each having a protruding transom connector on its facing side. A transom profile in the form of an open hollow profile with an outwardly open hollow chamber is then provided and slid onto the transom connectors on the mullion profiles, with the transom connectors being inserted into the hollow chamber of the transom profile. The transom profile is then secured to the transom connectors. This enables the efficient construction of a mullion-transom structure with a multitude of panels for receiving plate-shaped infill elements, in particular insulating glass units.

[0017] Preferably, at least two horizontal transom profiles are mounted on the two vertical mullion profiles, with an insulating glass unit being inserted into a circumferential groove on the two mullion profiles and the two transom profiles. The insulating glass unit can then be fixed in the groove by glazing beads, which are fixed to the two mullion profiles and the two transom profiles. Preferably, the glazing beads are fixed to an inner surface of the facade construction, which simplifies installation. For a visually appealing appearance, the glazing beads could be arranged flush with the inner surface of the mullion or transom profile in the installed position.

[0018] The invention is explained in more detail below with reference to an exemplary embodiment and the accompanying drawings. These show: Figures 1 to 3 show several views of the first steps in the assembly of a facade construction with two mullion profiles and transoms; Figures 4 to 6 show further views of the assembly of a facade construction during the installation of insulating glass units; Figures 7 to 9 show further views of the assembly of a facade construction before and during completion; Figure 10 shows a view of the facade construction during the installation of an insulating glass unit; Figure 11 shows a sectional view through two mullion profiles of the assembled facade construction; and Figure 12 shows a sectional view through two transom profiles of the assembled facade construction.

[0019] For the assembly of a facade structure, two post profiles 2 are first fixed vertically to a substrate. The post profiles 2 have projecting crossbar connectors 3 on their facing sides, which are fixed to a wall of the post profiles 2 by fasteners, for example, screws. The crossbar connectors 3 are essentially plate-shaped and can project, for example, between 10 mm and 100 mm from the post profile 2.

[0020] In Figure 2Several transom profiles 4 are shown before assembly. Each transom profile 4 is designed as an open hollow profile and comprises a hollow chamber 43 that is open on one longitudinal side of the transom profile 4. The transom profile 4 has a widened outer section with retaining strips 40, which is arranged on an outer surface of the facade construction. Insulating webs 41 made of a material with low thermal conductivity, for example, plastic, are provided between the outer section with the retaining strips 40 and a section containing the hollow chamber 43. The hollow chamber 43 is essentially cuboid in shape and is bounded on a top and a bottom by a profile wall 42. The height of the hollow chamber 43 can, for example, be between 5 mm and 50 mm.

[0021] For the installation of the transom profiles 4, these are slid onto the transom connectors 3 in a horizontal direction at opposite end faces. The installed position is in Figure 3shown, and the bar profiles 4 are flush with the post profiles 2 on one outside.

[0022] In a further step, the transom profiles 4 are fixed to the transom connectors 3 by means of fasteners 5, whereby screws are preferably used as fasteners 5, which are screwed into the profile walls 42 and the transom connectors 3 from a top and / or a bottom. Figure 4 Several bar profiles 4 are fixed between the two post profiles 2, and it is shown that glass supports and glazing elements 6 are arranged on the bar profiles 4, which serve to support the insulating glass panes yet to be installed.

[0023] In Figure 5The facade construction is shown not from an exterior but from an interior during the installation of insulating glass units 7. Each insulating glass unit 7 is first inserted into a groove on one of the mullion profiles 2 and then pivoted about a vertical axis. Once the edge of the insulating glass unit 7 is positioned in the area of ​​a groove on the second mullion profile 2, the insulating glass unit 7 can be moved towards the second mullion profile 2. This allows the insulating glass unit 7 to be inserted into a groove of a mullion profile 2 at opposite vertical edges (shuffle technique).

[0024] In Figure 6The fixing of the insulating glass panes 7 is shown. In a first step, glazing beads 8 are mounted, which are inserted into the two mullion profiles 2 to clamp the insulating glass panes 7 in place. The insulating glass panes 7 are each held between elastic sealing profiles, which are provided on the mullion profiles 2 and the glazing beads 8.

[0025] In Figure 7 Additional glazing beads 9 are mounted and attached to the mullion profiles 4. One glazing bead 9 is mounted on the top and one on the bottom of each mullion profile 4.

[0026] In Figure 8The assembly step for fixing a cover profile 10 is shown. The inwardly open hollow chamber 43 of the transom profiles 4 is closed on the inside by cover profiles 10, for example by means of a snap-fit ​​connection. This results in a closed design of the facade construction 1, which in the fully assembled position in Figure 9 shown.

[0027] In Figure 10Two mullion profiles 2 are shown in cross-section during the installation of an insulating glass unit 7. Each mullion profile 2 comprises a widened support section 20, a tapered central web 21, and an outer, wider retaining section 23. A groove 24 is formed between the support section 20 and the wider retaining section 23, with the groove bottom formed by the central web 21. The central web 21 is not a continuous metal profile but has at least one insulating web 22 made of a poorly thermally conductive material, such as plastic. The tapered central web 21 is not arranged centrally on the support section 20 but in Figure 10offset to the right side, so that the groove on the left side has a greater depth than the one on the opposite side. This allows the insulating glass pane 7 to be inserted with one edge into the groove 24 on the right mullion profile 2, and then pivoted on the opposite left side until the edge of the insulating glass pane 7 is also positioned in a groove 26 on the opposite side of the groove 24.

[0028] An elastic sealing profile 25 is fixed to the widened retaining section 23, so that the insulating glass pane 7 is supported on opposite sides by an elastic sealing profile 25.

[0029] In Figure 11The facade construction 1 is shown in the area of ​​the mullion profiles 2 in the assembled position. The insulating glass unit 7 is supported on the outside by the widened retaining section with the sealing profiles 25. Glazing beads 8 are mounted on an inside side of the insulating glass unit 7, each supported by a web 80 on retaining webs on the central web 21. The glazing beads 8 are provided with an elastic sealing profile 25 that rests against an inside side of the insulating glass unit 7. The at least one insulating web 22 in the area of ​​the central web 21 is arranged in the plane of the insulating glass units 7, thus optimizing the thermal insulation in this area.

[0030] In Figure 12The facade construction 1 is shown in section in the area of ​​the transom profiles 4 and transom connectors 3. The transom connectors 3 are hollow profiles with a truss structure, for example made of metal or plastic, and have screw channels so that screws can be screwed into the mullion profiles to fix the transom connectors 3. The transom connector 3 is surrounded on the top and bottom by a profile wall 42, the profile walls 42 being fixed by upper and / or lower fasteners 5 in the form of screws. The transom connector 3 extends on the outside to the area of ​​the insulating webs 41 on the transom profiles 4. On the outside, the transom profile 4 is provided with retaining strips 40, into which elastic sealing profiles 25 are inserted.The glazing beads 9 project from the top or bottom of the mullion profiles 4 and, together with the mullion profile 4, form a groove for receiving the edge of the insulating glass unit 7. The glazing beads 9 can be supported on the mullion profile 4 by one or more webs. Installation is preferably carried out by a pivoting motion to clamp the insulating glass unit between two sealing profiles 25. The mullion profiles 4 are arranged above a floor 12 of a building, with a support 13 fixed to the floor 12, onto which a mullion profile 2 is attached. The mullion profile 2 can also be fixed to a floor 12 by other fastening methods. A cover 14 is mounted on the outside of the floor 12, which is fixed to a mullion profile 4 above and below the floor 12. Reference symbol list
