Definitions

  • the invention relates to a sealing corner element, a combination of two hollow chamber seals and a sealing corner element and methods for producing a combination.
  • corner pieces are currently manufactured individually for each type of corner and either vulcanized separately or cut to size with great effort. In some cases, such corner pieces are then additionally glued. However, cutting and gluing in particular also represent potential weak points in the seal.
  • a sealing corner element for connecting two hollow chamber seals.
  • the sealing corner element has a wall on a first side which is shaped essentially the same as a wall of the corresponding side of the hollow chamber seals.
  • the sealing corner element has no further wall on a second side opposite the first side, at least in one bending area, wherein the bending area extends over the entire height of the sealing corner element and wherein at least one stabilizing element which can be plastically deformed by bending is arranged in the bending area.
  • the invention is based on the knowledge that a one-sided recess in the wall of a hollow chamber profile allows a simple bending of the hollow chamber profile, with which almost any bending angle can be set.
  • the invention includes the knowledge that a plastically deformable stabilizing element allows such a bending angle to be stabilized and thus provides a sealing corner element that can be used in a variety of different corners or angles and ensures both good sealing by accommodating the wall of the hollow chamber profile on one side and dimensional stability.
  • the sealing corner element according to the invention can be easily and tightly connected to a corresponding hollow chamber seal by continuing the hollow chamber profile of a hollow chamber seal on at least one side.
  • the sealing corner element has a hollow chamber area corresponding to at least one hollow chamber of the hollow chamber seals and at least one connection area. This can be used, for example, in receptacles of the facade elements.
  • the wall on the second side is therefore recessed over the entire width of the sealing corner element, which makes it easier to set acute angles.
  • the at least one stabilizing element can be arranged outside the hollow chamber area.
  • two stabilizing elements outside the hollow chamber area are preferred.
  • the at least one stabilizing element preferably comprises a metal plate, in particular a plate with prefabricated recesses, in particular with recesses that serve to facilitate plastic deformation.
  • Metal plates are simple and inexpensive to produce and, in particular with prefabricated recesses, offer easy deformability with good dimensional stability.
  • the at least one stabilizing element can be vulcanized or glued in, for example.
  • the sealing corner element can also have holding elements for the at least one stabilizing element.
  • the at least one stabilizing element can be vulcanized or inserted into these so that it is held in them by force and/or form locking.
  • the holding elements have an outer shape that essentially corresponds to the outer shape of a corresponding area of the hollow chamber seals.
  • This embodiment has the advantage that the shape of the hollow chamber seals is also continued in the holding elements and the sealing effect can thus be further improved via the continuous shape.
  • the invention relates to a combination of two hollow chamber seals and a sealing corner element according to the first aspect of the invention.
  • the combination comprises two hollow chamber seals, each with at least one hollow chamber and at least one sealing base for fastening to a facade element, and a sealing corner element with a hollow chamber region corresponding to the at least one hollow chamber of the hollow chamber seals and at least one connection region corresponding to the sealing base.
  • a stabilizing element is preferably arranged in the at least one connection region.
  • the hollow chamber seals comprise at least two sealing strips spaced apart from one another, forming a hollow chamber between them, which are each connected at the edge to a common sealing base designed for attachment to facade elements, wherein the sealing base is designed to accommodate is formed in profile grooves of the facade elements facing each other on the opening side, wherein each sealing strip is designed to be elastically deformable in the transverse direction of the profile in order to change its height and is connected by its edge in an articulated manner to the sealing base, wherein in particular at least one of the two sealing strips has a curved shape when viewed in cross-section and the sealing strips are connected to one another via a connecting web and wherein in particular the bulge is directed towards the side facing away from the other sealing strip and wherein this other sealing strip is designed in an accordion shape, wherein the accordion-shaped sealing strip is formed by an even number of sealing strips which are each connected to one another in an articulated manner, wherein the connecting web is arranged centrally on the sealing strips and wherein the sealing corner element has a
  • This design allows different distances between the facade elements to be compensated for by the sealing strips alone, while the sealing feet and connection areas remain completely within the profile grooves of the facade elements. On the one hand, this ensures better sealing of the sealing feet and connection areas in the profile grooves, and on the other hand, a more uniform visual appearance is achieved, since the deformations in a top view of the sealing strips always give a uniform appearance.
  • the hollow chamber seals each comprise two sealing feet and the sealing corner element contains two stabilizing elements, each of which is arranged in a connection area corresponding to the sealing feet. This gives the combination in the corner areas improved stability and sealing.
  • the wall of the sealing corner element corresponds to the shape of the accordion-shaped sealing strip. This allows further improved flexibility to be achieved.
  • the invention relates to a method for producing a combination according to the second aspect of the invention, in which the sealing corner element is manufactured separately, for example injection-molded, printed, cast or extruded, and in a further step is connected to the hollow chamber seals, for example by gluing.
  • the sealing corner element can be vulcanized onto the hollow chamber seals and at least one stabilizing element can be introduced during vulcanization or subsequently inserted or glued on.
  • the sealing corner element can be produced by cutting a hollow chamber sealing profile and inserting at least one stabilizing element.
