Description

[0001] The present invention relates to a renovation facade with a support profile on which at least one groove for holding a sealing profile is formed on an outer side, and on which a plate-shaped infill element is held, wherein an adapter profile with a seal is fixed on the support profile, which at least partially covers the at least one groove on the support profile, and the infill element is clamped to the adapter profile at the seal, wherein only a single seal is fixed on the adapter profile, which has two spaced-apart sealing strips on which an edge of an infill element rests, and a method for producing a renovation facade.

[0002] In building renovations, it is known from EP 3 574 752 B1 to provide a window unit comprising a frame and a box, which is fixed to the building using fasteners, and to place a layer of thermal insulation between the box and the building. This improves the thermal insulation of retrofitted windows. However, such a measure is unsuitable for facades, as there is no building opening there for fixing such a unit.

[0003] When renovating facades, the infill panels, mullions, and transoms are usually completely removed in order to install a new facade. This approach is very expensive, and the removed material requires complex disposal. In some cases, it is possible to replace only the infill panels, i.e., the glazing. However, this requires replacing the existing seals before installing the new panels, which can be problematic if the corresponding seal contour is no longer available. Furthermore, it is impossible to assess the condition of the facade or identify any weaknesses in the old one.

[0004] From DE 10 2012 007 088 A1, a system for the renovation of building facades is known in which an adapter profile is mounted on a mullion profile, which is screwed to the mullion profile and has a new screw receptacle. The adapter profile is surrounded on one outer side by a sealing profile with two sealing strips, wherein a sealing lip covers part of the adapter profile on a side wall, so that a step is visible between the sealing lip and the side wall of the adapter profile.

[0005] DE 195 19 219 A1 discloses a wood-aluminum post-and-beam construction in which elastic sealing profiles rest on the posts and beams. A support piece is attached to the beam between the sealing profiles.

[0006] EP2820973A1 discloses a profile connection with a profile and a component having a groove.

[0007] It is therefore an object of the present invention to provide an improved renovation facade and a method for producing a renovation facade in which the mounting of infill elements on a supporting profile is enabled in an effective manner.

[0008] This problem is solved with a renovation facade having the features of claim 1 and a method having the features of claim 12.

[0009] The renovation facade according to the invention comprises a support profile on which at least one groove for holding a sealing profile is formed on an outer side, in particular an undercut groove with a tapered neck section, and on which a plate-shaped infill element is held. An adapter profile with at least one seal is fixed to the support profile, the adapter profile(s) at least partially covering the at least one groove on the support profile, and the infill element being clamped to the adapter profile at the seal. The additional provision of an adapter profile with a seal allows the outer side of the support profile to be covered during renovation, particularly also in the area of ​​the at least one groove for the old sealing profile, so that a new infill element, for example an insulating glass unit, can be fixed to the adapter profile.This allows for effective facade renovation, as only the old infill panels and sealing profiles need to be removed from the support profiles. The adapter profile and at least one seal are then attached to the support profile. The adapter profile can be attached to different support profiles, allowing for flexible application. The new sealing profiles completely seal the old facade, creating the new sealing layer. The renovation facade is designed as an add-on construction, where the adapter profiles and other components are attached to and fixed on the outer side of the support profile.

[0010] Preferably, the adapter profile is screwed to the support profile. The adapter profile can be supplied in the same length as the support profiles, for example, if the support profile is designed as a post or rail in a post-and-beam or rail-and-beam construction. In this case, at least one adapter profile can be screwed to each of several support profiles, allowing the adapter profiles to be arranged around the perimeter to form a frame. The support profiles and / or the seals compensate for the offset planes of the facade and create a new plane for the sealing profile. It is also possible for the attached profiles and seals to create a plane offset. The sealing profile can then be fixed to each adapter profile before or after installation, in order to then fix the infill elements to the at least one seal.

[0011] The adapter profile can be efficiently manufactured from metal or plastic, for example using extrusion. For particularly high thermal insulation, the adapter profile can at least include plastic or be made entirely of plastic.

[0012] In one embodiment according to the invention, the adapter profile has a narrower width than the support profile, with the adapter profile being enclosed by the seal on opposite sides. This means that only the seal is visible on the sides of the adapter profile, so that in the assembled position the adapter profile is concealed within a cavity between the support profile and the seal. Therefore, after assembly, only the seal and the support profile are visible to the user.

[0013] For efficient assembly, the adapter profile can have a screw groove that is arranged in a direction perpendicular to the plane of the infill element, extending from a screw groove on the support profile. This allows the fasteners, especially the screws, to be positioned centrally between two infill elements for easy installation. Openings, such as round or elongated holes, can also be provided for fasteners like screws or rivets, which define the spacing of the screws.

[0014] The adapter profile, including the seal, preferably has the same width as the support profile and the existing facade. This allows the support profile to be flush with the seal at the transition point, resulting in an aesthetically pleasing appearance. For efficient installation, only a single seal needs to be attached to the adapter profile. This seal is held, for example, by a screw groove in the adapter profile and features two spaced sealing strips, each supporting an edge of an infill element. The seal can then be mounted to the adapter profile in just a few steps, after which the entire assembly of adapter profile and seal is fixed to the support profile. Furthermore, the sealing strips preferably have a greater thickness than the connecting section between them.

[0015] Preferably, a strip-shaped insulating element is held in a screw groove of the adapter profile, engaging between two infill elements. This improves the thermal insulation of the newly installed facade construction, as the area between the two infill elements is better insulated.

[0016] A pressure profile is preferably provided on the outside of the infill element, which is screwed to the adapter profile. This prevents a thermal bridge from the pressure profile to the support profile, since the pressure profile is only screwed to the adapter profile and the adapter profile in turn to the support profile.

[0017] In a further embodiment, the adapter profile has at least one web that extends perpendicularly in cross-section to a plane of the infill element and is supported on the load-bearing profile. This improves the stability of the renovated facade, particularly if the adapter profile has two webs arranged on opposite sides of a screw groove in the load-bearing profile, so that the adapter profile is held against a stop or support web of the load-bearing profile.

[0018] In an inventive method for producing a renovated facade, old infill panels and old seals are first removed from a plurality of support profiles, with the old seals being removed from a groove in each support profile. The support profiles, for example in a post-and-beam construction, are then used, with an adapter profile having at least one seal being fixed to an outer side of the support profile, covering the at least one groove on the support profile. Then, at least one infill panel is fixed to the adapter profile at the at least one seal, for example by means of a pressure strip. Such a method enables a particularly effective renovation if the at least one seal is fixed to the adapter profile before the adapter profile is fixed to the support profile.The seal can be pre-attached, for example, by the metal fabrication company or the adapter profile manufacturer, allowing the adapter profile and seal unit to be installed as a single unit. The adapter profile with the seal simply needs to be cut to the required length and then mounted to the supporting profiles. Such a renovated facade can be designed as a post-and-beam construction, a unitized curtain wall, or another type of facade construction. By covering the existing building connections, a membrane or other material can be attached to the new sealing profile. This conceals these connections and eliminates any leaks.

[0019] The invention is explained in more detail below with reference to two exemplary embodiments and the accompanying drawings. These show: Figure 1 shows a sectional view through a first embodiment of a renovation facade according to the invention, and Figure 2 shows a sectional view through a second embodiment of a renovation facade according to the invention.

[0020] A renovation facade 1 comprises a support profile 2, which is designed, for example, as a mullion or transom of a mullion-transom construction. Transoms 3, shown schematically, are fixed to the support profile 2. Two support profiles 2 and two transoms 3 can form a continuous frame for fixing an infill element 4. The infill element 4 is shown here as an insulating glass unit, but it can also be formed by other plate-shaped infill elements. Two infill elements 4 are held on the support profile 2, although it is also possible to fix only a single infill element 4 to the support profile 2 or more than two infill elements 4 arranged side by side along the longitudinal direction of the support profile 2.

[0021] The support profile 2 can be fixed to a building and was part of a facade from which the old infill panels and seals had been removed. The support profile 2 includes a central screw groove 25 on one outer side and, on opposite sides of the screw groove 25, an undercut groove 22 with inwardly projecting webs for holding a base element of a removed seal. The groove 22 comprises an inner groove wall 23 and an outer groove wall 24, the outer groove wall 24 being an extension of a web 21 connected to a cuboid section of the support profile 2. The cuboid section of the support profile 2 includes a base 20 that is aligned parallel to the plane of the infill panels 4.

[0022] To mount the new infill elements 4 onto the existing support profile 2, an adapter profile 5 is provided, which is made, for example, of metal, plastic, or a composite material and is connected to the support profile 2 by screws 7. The screws 7 pass through a web 52 of the adapter profile 5, which is oriented essentially perpendicular to two groove walls 51 of a screw groove 50 of the adapter profile 5. In the mounted position, the screw groove 50 is oriented in a direction perpendicular to the plane of the infill elements 4, extending from the screw groove 25 of the support profile 2. Two angled retaining sections 53 are located on the web 52 of the adapter profile, which serve to fix a seal 6. The web 52 is supported on opposite sides against an outer surface of the inner groove wall 23 of the two grooves 22.

[0023] In this embodiment, the adapter profile 5 also includes optional support webs 54, which are arranged on both sides of the screw groove 25 of the support profile 2 and are supported on the base 20. The two screws 7 extend through the web 52 and the base 20 of the support profile 2 to fix the adapter profile 5 to the support profile 2. A plurality of screws 7 can be provided along the length of the adapter profile 5.

[0024] The seal 6 comprises a fastening section 60 that engages the angled retaining section 53, the two fastening sections 60 of the seal being connected to each other via a U-shaped connecting section 63. The connecting section 63 engages the screw groove 50 of the adapter profile 5 and optionally has a fastening rib 64 that engages in the screw groove 50. The seal 6 is preferably formed in one piece and can therefore be easily mounted on the adapter profile 5. The seal 6 further comprises two sealing strips 61, which are arranged on opposite sides of the screw groove 50 and on which an edge of a filling element 4 rests.

[0025] The adapter profile 5 has a narrower width perpendicular to the longitudinal direction than the support profile 2. The adapter profile 5 is enclosed on opposite sides at the angled retaining section 53 by the seal 6, with a lateral surface 62 of the seal being essentially flush with a lateral surface of the support profile 2 in the area of ​​the transition between the support profile 2 and the seal 6. As a result, after the installation of the renovation facade 1, the adapter profile 5 is concealed, and only the support profile 2 and the seal 6 are visible from the outside.

[0026] To increase thermal insulation, an insulating element 8 is held in the screw groove 50 of the adapter profile 5. This insulating element is strip-shaped and positioned in a gap between the two adjacent filling elements 4. The strip-shaped insulating element 8 can be made of a foamed material and may optionally have lateral sealing lips to improve thermal insulation.

[0027] The infill elements 4 are held on the support profile 2 by a pressure profile 9, the pressure profile 9 comprising two receptacles for sealing strips 10. These sealing strips rest against an edge of the respective infill element 4 and press the infill element 4 against the sealing strip 61 of the gasket 6. The pressure profile 9 is fixed to the adapter profile 5 by screws (not shown), which engage in the screw groove 50 of the adapter profile 5. This prevents direct heat transfer from the screws on the pressure profile 9 to the support profile 2. The pressure profile 9 is covered on the outside by a cover strip 11.

[0028] In Figure 2A modified renovation facade 1' is shown, in which a different support profile 2' is provided. As in the previous embodiment, the support profile 2' comprises two undercut grooves 22 with an inner groove wall 23 and an outer groove wall 24, the grooves 22 being arranged on opposite sides of a screw groove 25. An adapter profile 5' is fixed to the support profile 2', which is designed similarly to the previous embodiment, except for a groove in which the groove walls of the screw groove 25 of the support profile 2' are received. This improves the lateral fixation of the adapter profile 5' to the support profile 2'. Otherwise, the adapter profile 5' comprises, as in the previous embodiment, a screw groove 50 and two retaining sections 53 to which fastening sections 60 of the seal 6 are fixed. The seal 6, as well as the infill elements 4 and the pressure profile 9, are designed as in the previous embodiment.The support profile 2' has a significantly smaller extent perpendicular to the plane of the infill elements 4, so that shorter screws 7' are used for mounting the adapter profile 5'.

[0029] The adapter profiles 5 or 5' can be mounted on different support profiles 2 or 2', which may have different geometries on their outer surfaces. This allows the adapter profile 5 or 5' to be used flexibly with different support profiles 2 or 2'.

[0030] In a process for producing a renovation facade, old infill elements and old seals are first removed from the undercut grooves 22 of a large number of support profiles 2 or 2'. The old seals are pulled out of a groove 22 on the support profiles 2 or 2' and any other components are removed.

[0031] An adapter profile 5 and at least one seal 6 are then fixed to an outer side of the support profile 2, 2', in particular by means of screws 7, 7', whereby the at least one groove 22 on the support profile 2 or 2' is covered. At least one filling element 4 is then fixed to the at least one seal 6 on the adapter profile 5. Preferably, the seal 6 is mounted on the adapter profile 5 after its manufacture, and these are then delivered to the construction site as a unit so that the adapter profile 5 and seal 6 can be fixed together to the support profile 2 or 2'.

[0032] The support profile 2, 2' can, for example, be made of metal, in particular as an extruded aluminum profile. However, the support profile 2 can also be made of steel, wood, or various other materials. Reference symbol list
