Definitions

  • the invention relates to a sealing arrangement for sealing the transition between facade elements of an element facade.
  • the invention also relates to an element facade with such a sealing arrangement.
  • elemental facades consist of modular facade elements that can be completely prefabricated in the factory and assembled on site.
  • the individual prefabricated facade elements can be easily assembled on the construction site from bottom to top and can be sealed against each other using suitable seals.
  • DE 101 53 071 A1 discloses a sealing profile and a sealing connection for a post and transom arrangement. To form a sealing connection between a horizontal and a vertical sealing profile, a stainless steel plate is inserted into the front of one of the sealing profiles, with a projection of the stainless steel plate protruding from the sealing profile being inserted into a central slot on the side flank of the other sealing profile. Therefore revealed DE 101 53 071 A1 the features of the preamble of claim 1.
  • DE 10 2011 011 055 A1 further discloses a pressure strip seal for contact with facade elements.
  • the object of the invention is to create a sealing arrangement for sealing the transition between facade elements of an element facade and an element facade with such a sealing arrangement, which enable quick and safe assembly with improved sealing.
  • the sealing arrangement according to the invention for sealing the transition between facade elements of an element facade comprises a saddle seal for sealing the horizontal transition between the facade elements and a coupling seal which can be connected to the saddle seal for sealing the vertical transition between the facade elements, the coupling seal being a co-extruded seal with a softer outer jacket and a harder core that can be inserted into an opening in the saddle seal and bonded to the saddle seal.
  • the coupling seal has a protrusion of the harder core at its upper and lower ends relative to the outer jacket for engagement in the opening of the saddle seal.
  • the protrusion of the hard core can expediently be produced by cutting the softer sheath at a desired location up to the harder core, as with a power cable, and pulling it off from the core.
  • the core can have a Shore hardness between 70 and 95 and the jacket can have a Shore hardness between 30 and 60.
  • the opening in the saddle seal provided for receiving the core of the coupling seal can be designed as a cutout in a cover arranged above a receiving channel of the saddle seal and molded onto it.
  • the cover can be provided with appropriate separating slots on its edges.
  • the saddle seal can contain an elastically flexible sealing body provided with an adhesive area for sealing the transition between horizontal frame elements of two horizontal facade elements arranged one above the other.
  • the adhesive area can be formed by a groove on the top of the sealing body.
  • the saddle seal can also have a web, which is expediently designed to engage in internal profiles of two horizontal facade elements arranged one above the other.
  • the web of the saddle seal can have a groove for receiving a support bracket.
  • the saddle seal can be fixed using the support bracket.
  • the saddle seal can also contain a nose for mounting in an outer profile of a horizontal facade element.
  • the invention also relates to an element facade in which the horizontal and vertical transitions between the facade elements formed with horizontal and vertical frame elements are sealed via a sealing arrangement described above.
  • FIG 1 is a horizontal section and in Figure 2 a vertical section of a transition area or element joint of two facade elements of an element facade formed with vertical frame elements 1 and horizontal frame elements 2 is shown.
  • An element facade is usually formed by several facade elements arranged next to one another and one above the other. These facade elements can be completely prefabricated in the factory and assembled on site.
  • the lower facade elements are first attached to a supporting structure. Further facade elements are then placed on the lower facade elements and connected to each other using sealing elements. This means that large-scale facades can be installed easily.
  • the vertical and horizontal frame elements 1 and 2 forming a frame of the facade elements are a wood-metal construction with a support 3 or a cross member 4 made of wood and holding elements 5 attached thereto for fastening glass panes, panels or other facade elements 6 executed.
  • the supports 3 and cross members 4 form a support frame made of wood to which the holding elements 5 are attached.
  • the holding elements 5 are designed as composite profiles with an inner profile 7 and an outer profile 9 connected to it via insulating webs 8.
  • the support frame formed from the vertical supports 3 and the horizontal cross members 4 is made of wood in the embodiment shown, but can also be made of metal, plastic or another suitable material.
  • the inner profile 7 and outer profile 9 are preferably made of aluminum, while the insulating webs 8 are preferably made of hard plastic.
  • the composite profile is attached to the support 3 or the cross member 4 by means of screws 10 and 11 via the inner profile 7, which is preferably made of aluminum.
  • the inner profile 7 also contains a screw channel 15 for a fastening screw 16 for fastening a pressure strip 17 on its front end facing away from the support 3 or the cross member 4.
  • the side facing the frame elements 1 and 2 of the next facade element is used as the outside of the inner profile 7 and the outer profile 9 and the side facing the facade element is used as the inside 6 pointing side designated.
  • the pressure strip 17, which is fastened to the inner profile 7 via the fastening screw 16, has two mutually parallel receiving grooves 21 for receiving two outer seals 22.
  • a cover 23 is attached to the press bar 17 via a clip connection.
  • Figure 1 For sealing the vertical transition between the two successive vertical frame elements 1 of two facade elements arranged next to one another in the two receiving channels 12 of the inner profiles 7 arranged next to one another, one is also in Figure 3 shown and in Figure 4 vertical coupling seal 24 shown separately is used.
  • Figure 2 The horizontal transition shown between the two horizontal frame elements 2 arranged one above the other of two facade elements arranged one above the other also serves in Figure 3 shown and in Figure 5 saddle seal 25 shown separately, which can be connected to the coupling seal 24.
  • the coupling seal 24 is designed as a co-extruded seal with a harder core 26 and a softer outer jacket 27.
  • the outer jacket 27 for example, has a Shore hardness of 50 and the harder core has a Shore hardness of 90.
  • the strip-shaped coupling seal 24 contains a core 26 with a rectangular cross-section and a jacket 27 surrounding it, on which outwardly projecting sealing lips 28 and 29 are provided for sealing contact with the inner walls of the receiving channels 12.
  • the softer jacket 27 can be cut and removed at a desired location up to the harder core 26, so that a desired projection 30 of a rectangular hard part of the core 26 is left on the top and bottom of the coupling seal 24 for positive engagement with the Saddle seal 25 remains.
  • the saddle seal 25 has a rear web 31 for engaging in the two recesses 12 of two inner profiles 7 arranged one above the other on the upper and lower horizontal frame elements 2 of two facade elements arranged one above the other.
  • the saddle seal 25 also contains a cover 32 projecting forward from the web 31, which projects over the inner profile 7, the upper insulating web 8 and the outer profile 9 of a holding element 5 on a horizontal frame element 2 of the lower facade elements and at its front end over a molded one Nose 33 is held in a receiving channel 18 of the outer profile 9.
  • an upwardly projecting, elastically flexible sealing body 34 is formed on the side of the cover 32 facing away from the nose 33.
  • the saddle seal is additionally fixed via a support bracket 36 which engages in a groove 35 in the web 31 and can be fastened to the cross member 4 by means of the screw 11.
  • the sealing body 34 designed as a hollow body, is used to rest on a flat seal 37, which is arranged on the outer profile 9 of a holding element 5 on a horizontal frame element 2 of an upper facade element.
  • the saddle seal 25 seals the horizontal distance between facade elements arranged one above the other.
  • the saddle seal 25 on the top and bottom of the web 31 each has a receiving groove 39 closed by means of a cover 38 for receiving the projection 30 of the coupling seal 24.
  • the cover 38 is included on its edges Separating slots 40 are provided to form a separating contour. As a result, the cover 38 can be easily separated at certain points and the receiving groove 39 can be exposed there for connection to the coupling seal 24.
  • the contour of the receiving groove 39 is matched to the contour of the harder core of the coupling seal 24, so that the projection fits exactly into the receiving groove 39.
  • the receiving groove 39 has a width corresponding to the thickness of the core.
  • the sealing body 34 contains an adhesive area 41 on its upper side facing the flat gasket 37 for a firm connection to the flat gasket 37. In the embodiment shown, the adhesive area 41 is designed as a groove for introducing an adhesive.
