Definitions

  • the present invention relates to a composite profile for doors, windows or facade elements according to the preamble of claim 1.
  • Such composite profiles for doors, windows and other facade elements are known from the prior art. So will in the DE 20 2013 105 101 U1 discloses a composite profile that has a first and a second metallic outer profile, each with at least one hollow chamber. A middle profile made of a metallic material is arranged between the two outer profiles. The metallic central profile is connected to the first outer profile via one or more spaced insulating bars and to the second outer profile also via at least one or more spaced insulating bars, so that good thermal insulation is achieved and relatively long protection against flame transmission in the event of a fire is achieved.
  • a preferred - but not mandatory - field of application of such composite profiles, which have more than two metallic profile sections, is the use as door profiles in the interior of buildings with special fire protection requirements.
  • shear stresses occur between the components of the composite profile when the temperature increases or decreases on one side, as occurs with seasonal changes. Due to the shear strength of the composite profile structure, the shear stresses result in deformations of the composite profile, resulting in a curvature towards the warmer side of the composite profile. Such deformations can impair the function of the door or window frame constructed from the composite profile.
  • the temperature-related deformation of the composite profiles has a negative effect on the function of the seals and locking systems, particularly in the case of relatively long composite profiles that are used as door frame members.
  • an insulating strip has at least two or more insulating strip sections or parts that can be moved relative to one another and are connected to one another via webs, the webs being designed in such a way that the two insulating strip parts of the insulating strip can be moved relative to one another to a limited extent in such a way that adjacent webs and the insulating strip parts can be pivoted into a parallelogram shape during movement.
  • a disadvantage of the solutions of the prior art is that a relatively low moment of inertia results from a shear-flexible or shear-free design of the insulating strips between the profiles.
  • a composite profile with non-shearing or shear-resistant insulating bars results in a smaller glazing area and less incidence of light than a composite profile with shear-resistant insulating bars with the same wall opening area.
  • the thermal insulation properties of the composite profiles with shearless or shear-flexible insulating strips according to the prior art are poorer than those of such composite profiles according to the prior art which have more than two metallic profile sections.
  • the invention therefore has the object of specifying a generic composite profile for doors, windows or the like, which at least reduces these problems.
  • the present invention solves this problem by the subject matter of claim 1.
  • the invention also provides a window or a door or a facade element with at least one or more composite profiles according to the claim relating thereto.
  • Advantageous refinements of the invention are specified in the dependent claims.
  • the two insulating strip zones have different shear strengths orthogonally to the cross-sectional plane of the composite profile. This can be achieved in particular by creating a shear-resistant connection between all of the elements connected to one another in the first insulating strip zone (this includes one-piece insulating strips or multi-part insulating strips with their insulating strip sections and the adjoining metal profiles, i.e. the middle metal profile and the associated outer metal profile or outer profile) is provided or designed, whereas in the second insulating strip zone the shear strength of the elements connected to each other in the second insulating strip zone (insulating strips, metal profiles or insulating strip sections) is in any case partially or in sections lower than in the first insulating strip zone.
  • the invention creates such a composite profile for doors, windows or the like, which ensures deformation of the profile under the influence of temperature due to different shear strengths of the insulating strip zones and preferably in particular a shear-free or shear-flexible design of an insulating strip zone. This results in a surprisingly high rigidity of the composite profile despite the reduced shear design of one of the two insulating bar zones.
  • the reduction in shear strength in one of the two insulating bar zones can be implemented in various ways. Reference should first be made to the essential basic principles of reduced shear strength EP 0 829 609 A2 . Variants of the thought of this writing show the DE 10 2004 038 868 A1 , the DE 10 2013 204 693 A1 the EP 1 004 739 B1 and the DE 199 62 964 A1 .
  • the zone with reduced shear strength can be designed as in these documents. So it can be designed as a sliding guide, which is formed between the insulating profile and one or both adjacent metal profiles. However, the sliding guide can also be formed between two insulating profile sections. The friction in the sliding guide does not have to be close to zero.
  • shear strength here should be lower overall over the length of the composite profile (based on a unit length, e.g. 1 m) than in the other insulating strip zone.
  • the two insulating bar sections can also consist of different materials and/or be connected to one another with limited mobility via transverse bars or the like. Combinations of these measures and other shear-reducing measures relative to a shear-resistant connection are also conceivable.
  • the shear strength is higher than in the other insulating bar zone.
  • This connection is preferably even shear-resistant, ie within the meaning of this document, suitable measures and means are used to prevent relative movement of the elements to be connected in the insulating strip zone "insulating strips” or “Bar sections or parts” and “metal profiles” prevented in this zone as a result of expansion. This can easily be achieved by rolling metal profile webs onto the heads or end sections of the insulating strips and by additional measures such as wires with variable thickness in the longitudinal direction or a knurled wire or the like in the rolling area.
  • a shear-free bond - occasionally also referred to as a shear-flexible bond - allows a relative movement of the adjoining elements "insulating strips” or “insulating strip sections or parts” and “metal profiles" in this insulating strip zone that are to be connected to one another as a result of dilatation in any case limited to.
  • the composite profile has one or more insulating bars that have thickened end sections, wherein the respective end section can have a trapezoidal or triangular or wedge-shaped or L-shaped cross section and the respective end section engages in a groove of a metal profile.
  • the insulating bars of the composite profile have an end section for realizing a type of sliding guide, which has a substantially welt-like cross section, which engages in a groove of a metal profile.
  • the insulating bars of the composite profile are made of two insulating bar sections or parts, the two parts of the insulating bars being positively connected to one another in the direction of cross-sectional expansion of the composite profile by a piping connection. This also serves to implement a sliding guide.
  • the keder connection has a keder bead and a keder flap, which engages in a groove with a corresponding cross-sectional geometry.
  • the friction-minimizing means can be applied easily, as is the case with a co-extruded film that is applied to the welt bead of the welt connection.
  • the film of the co-extruded film, which is connected to the groove has a particularly low coefficient of friction in this case, so that a connection that is virtually shear-free in a direction orthogonal to the cross-sectional plane of the composite profile is created.
  • the composite profile has at least one or more hollow chambers, with at least one thermal insulation strip being inserted into one or more of these hollow chambers. As a result, the thermal insulation properties of the composite profile are improved even further in a simple and advantageous manner.
  • fire protection strips are arranged in place of the thermal insulation strips or additionally in other hollow chambers.
  • the fire protection properties of the composite profile are additionally improved even further in a simple and advantageous manner. It is particularly advantageous if the fire protection strips are each made of a material which has the property of causing an endothermic reaction on combustion, as is advantageously the case when the fire protection strips are made of a material containing water of crystallization.
  • a composite profile 1 according to the invention is shown.
  • This composite profile 1 can be used as a casement profile as part of a casement or window frame for doors, windows or other facade elements, so that the following description relates equally to casement profiles and window frame profiles.
  • the composite profile 1 has a first metal profile, a metal outer profile 2, in which at least one hollow chamber 3 is formed, and a second metal outer profile 4, in which at least one hollow chamber 5 is also formed. Between the two metal profiles 2 and 4 there is a third metal profile, a metal middle profile 6, in which at least one hollow chamber 7 is also formed.
  • the metallic profiles 2, 4, 6 can also be designed without pronounced hollow chambers 3, 5, 7 or have several hollow chambers.
  • the first metal outer profile 2 is connected to the metal middle profile 6 via at least one or more first insulating bars (here parallel) 8 . These insulating strips 8 between the first metallic outer profile 2 and the metallic central profile 6 form a first insulating strip zone I or level.
  • the second metal outer profile 4 is also connected to the metal middle profile 6 via at least one or more second (here parallel) insulating webs 9 . The insulating strips 9 between the second metallic outer profile 4 and the metallic central profile 6 form a second insulating strip zone II or plane.
  • the first and second insulating bars 8, 9 have here - purely by way of example - no hollow chamber.
  • the insulating bars 8, 9 can also have one or more hollow chambers, or the respective first or the respective second insulating bars can be combined by transverse bars to form a type of superordinate insulating profile.
  • the insulating bars 8, 9 of the insulating bar zones I, II are here - purely by way of example - in one plane. Alternatively, it is also possible for the insulating strips 8, 9 of the insulating strip zones I, II to be offset vertically and/or horizontally with respect to one another.
  • the first and second metal outer profiles 2 and 4 and the metal middle profile 6 are preferably produced as extruded aluminum profiles. Alternatively, production from a different material such as steel and/or a different manufacturing process is also possible.
  • the insulating webs 8 and 9 are made of a material that reduces the passage of heat, preferably a plastic material such as polyurethane, so that an extensive thermal separation between the metal profiles 2, 4, 6 is achieved in each case.
  • metallic insulating bars with reduced heat transmission can also be used, which can be provided with interruptions or recesses to reduce heat transmission (e.g. in EP 0 717 165 A2 disclosed).

  • the respective end section 10 preferably has a trapezoidal or triangular or wedge-shaped or L-shaped or rectangular cross-section.
  • the respective groove 11 accordingly has a cross section with a corresponding cross section in each case.
  • the second insulating strip zone II has the second insulating strips 9, the respective end sections 10 of which are positively and non-positively connected to the respective groove 11, so that one in each case is also in the z-direction (cf. coordinate system in 1 ) or in a direction orthogonal to the cross-sectional plane of the composite profile 1 results in a shear-resistant connection between the second insulating bars 9 and the outer and middle metal profiles adjacent to them.
  • This connection is also referred to below as a shear-resistant design of one of the two - here the second - insulating strip zones. It provides shear resistance against the forces occurring due to dilatation on a window or door or the like.
  • the shear strength of the other - here the first - insulating bar zone I is in all variants lower than that of the first insulating bar zone II. It is selected in such a way that a displacement of at least two elements in the insulating bar zone relative to each other as a result of dilatation is possible.
  • Insulating strip zone I with lower shear strength when installed is preferably on a window or door on the outside of a building, since the temperature differences here are greater than on the inside of the building, so that the lower shear strength is particularly important here to compensate for dilatation effects is.
  • the insulating strip zone with increased shear strength is preferred. This variant of the invention is particularly advantageous. However, it is also conceivable to provide the insulating strip zone with higher shear strength towards the outside of the room.
