Definitions

  • the present invention relates to a composite profile, in particular for facades, windows or doors, with a first profile and a second profile fixed to the first profile, which has a higher flexural strength than the first profile, the first profile having at least one profile on the second profile Fastening means is fixed in a shear-proof manner, as well as a frame and an element facade.
  • the EP 3 354 835 B1 discloses a composite profile for a facade, door or window, which has a plurality of profiles made of an aluminum alloy, which are fixed to one another in the longitudinal direction.
  • the third profile made of an aluminum alloy can absorb higher mechanical loads and is made of a different material than the other two profiles made of an aluminum alloy.
  • Such composite profiles have proven themselves, but there is a problem when the different materials have a different coefficient of thermal expansion. A change in temperature, for example due to solar radiation, then ensures a different length of the profiles and consequently a deflection, which is also referred to as the bimetal effect.
  • the composite profiles bend towards one another or away from one another from their connection point, which leads to deflection and associated problems or leaks during assembly or in the installation position.
  • the composite profile according to the invention has a first profile with higher flexural strength than a second profile, so that higher loads can be absorbed via the first profile.
  • the first profile is fixed in a shear-proof manner on the second profile via at least one fastening means, the first profile and the second profile being displaceable parallel to the longitudinal direction via a linear guide arranged at a distance from the at least one fastening means are held.
  • a shear-proof connection is established via the fastening means, while the linear guide enables the first profile to move relative to the second profile.
  • thermal stresses between the first and the second profile can thus be better balanced out, since a movement in the longitudinal direction between the two profiles is made possible via the linear guide.
  • the linear guide preferably enables the profiles to move relative to one another in the longitudinal direction, but blocks a movement perpendicular thereto, so that a relative movement between the first profile and the second profile is only permitted in the longitudinal direction.
  • the second profile is preferably U-shaped in cross-section or comprises a U-shaped section, the at least one fastening means for shear-proof fixation being provided on a first leg of the U and the linear guide being provided on the second leg.
  • each leg can be fixed or slidably held on the first profile.
  • a groove and at least one web engaging in the groove can be formed, both of which can be formed integrally with the first profile and the second profile.
  • a corresponding linear guide can also be provided by further components.
  • the linear guide can optionally have a guide element, for example a screw or a bolt, which engages in an elongated hole on the first or the second profile and thus effects a guide, but allows relative movement in the longitudinal direction through the elongated hole within certain limits.
  • a guide element for example a screw or a bolt
  • the at least one fastening means for the shear-proof fixing can reach through an opening in the first profile and an opening in the second profile.
  • the fastening means can be designed as a screw, bolt or rivet.
  • Mechanical fixation by clinching or other forming processes to produce a shear-proof fixation is also possible.
  • the fixation can also take place by welding, in particular spot welding.
  • the second profile preferably has an average wall thickness that is at least 20% greater than that of the first profile.
  • Both profiles can be designed as extrusion profiles, the first profile having a smaller average wall thickness and being more filigree, for example in order to produce grooves, webs and other filigree sections.
  • the second profile is intended to absorb higher static loads and is therefore designed to be thicker in wall thickness.
  • the second profile can also be made of a different material than the first profile, for example a different aluminum alloy or steel.
  • the first profile can be an extruded aluminum profile, but also an extruded plastic profile, for example with fillers.
  • the second profile preferably has a material with a different coefficient of thermal expansion than the first profile, so that there is a relative displacement between the first and the second profile in the event of temperature differences.
  • the composite profile according to the invention is preferably used in a frame which is used to produce a facade, a window or a door, at least one frame profile, in particular all frame profiles, being produced from the composite profile.
  • an insulating glass pane or a plate-shaped filling element can be fixed to an outside of the frame and held on the first profile, the second profile being arranged on a section of the first profile facing an inside.
  • the at least one fastening means for shear-proof fixation can be arranged closer to the outside than the linear guide.
  • a reinforcement of the first profile by the second profile on the section facing the inside can bring about a narrow but deep shape of the composite profile which, despite the narrow design, can absorb comparatively high loads.
  • An element facade comprises a multiplicity of elements, each of which has a frame, in particular with one or more infill elements, an adjacent element resting on at least one side of the frame. This allows facades to be produced in a modular manner, with the individual elements being sealed off relative to one another.
  • An element facade 50 comprises several elements with a surrounding frame, with at least one frame of an adjacent element being arranged on each element.
  • Each frame is formed by a composite profile 1 on at least one side, preferably on all sides.
  • the individual composite profiles 1 are fixed to one another in the miter area by corner connectors 3.
  • a carrier 4 with a T-shaped cross section can be arranged on at least one side of the frame, which carrier 4 forms a linear guide for at least two profiles of the composite profile.
  • the carrier 4 is fixed to one of the composite profiles 1 by means of screws 5.
  • FIG 2 a sectional view through two adjacent composite profiles 1 and 1 'is shown, which are assigned to two adjacent elements of an element facade 50.
  • the upper composite profile 1 has a first profile and a second profile 10 fixed to the first profile 2.
  • the lower profile 2 ′ does not have a second profile 10, but can optionally be constructed identically to the upper composite profile 1.
  • the profile 2 has a groove 20 for inserting a sealing profile 22, which rests against an edge of the filling element 6.
  • a screw groove 21 is formed which has fine corrugation on the inner sides and into which screws can be screwed for fixing a pressure strip 7.
  • An insulating strip 23 is located in the screw groove 21 inserted in order to bridge a distance between the profile 2 and the pressure strip 7.
  • the pressure strip 7 presses with a seal 24 against the outside of the filling element 6.
  • the pressure strip 7 is covered by a cover strip 25 so that no fastening means are visible.
  • a section of the composite profile 1 facing an inside is reinforced by a second profile 10, which has a higher flexural strength than the first profile 2. This is achieved, for example, in that the second profile 10 is formed with a significantly thicker wall thickness or made of a material with higher flexural strength.
  • the profile 2 is sealed on the outer circumference with respect to the adjacent profile 2 ′, a seal 8 being inserted in opposite grooves of the insulating strip 23 for this purpose.
  • Another sealing element 9 is inserted into mutually facing grooves of the profiles 2 and 2 '.
  • the second profile 10 is fixed to the first profile 2 in a shear-proof manner by means of a fastening means 11, in particular a bolt, a screw, a rivet or by other fastening means.
  • the second profile 10 is essentially U-shaped in cross section, the fastening means 11 being arranged on a bend of a first leg.
  • a linear guide is formed on the second leg so that a displacement in the longitudinal direction between the first profile and the second profile 10 can take place.
  • the linear guide is formed by a screw 12 which passes through an elongated hole in the first profile 2.
  • FIG 3 a section through the first profile 2 and the second profile 10 is shown without the other components. It can be seen that the first profile 2 has an average wall thickness that is significantly smaller, for example at least 30% thinner than the average wall thickness of the second profile 10.
  • the first profile 2 has integrally formed grooves 20, 26 and 27, which serve to accommodate various sealing profiles or other components.
  • the second profile 10 reinforces the first profile 2 on a section which faces the inside of the profile 2, while the filling element 6 is fixed on the outside.
  • the second profile 10 comprises a leg 19 on which the fastening means 11 is arranged in order to fix this leg 19 in a shear-proof manner on the first profile 2.
  • the second leg 19 'of the second profile 10 is connected to the first via a screw 12 Profile 2 held, wherein the screw 12 is screwed into the first profile 2 and an elongated hole 16 extends through the leg 19 '.
  • a screw head 14 is arranged on the elongated hole 16 via a washer 13, so that in the area of the elongated hole a relative displacement of the leg 19 ′ to the first profile 2 can take place in the longitudinal direction.
  • a bow-shaped central section 18 between the two legs 19 and 19 ' is connected to the T-shaped insert and also guided in the longitudinal direction.
  • FIG 4 a modified embodiment of the first profile 2 is shown, to which a second profile 10 is fixed.
  • the second profile 10 has a U-shaped section with a central section 30 and two legs 31 and 36. Integrally formed on the leg 31 is a web 32 which engages in a groove, in particular an undercut groove with inwardly protruding webs, on the first profile 2.
  • the first leg 31 is fixed to the first profile 2 in a shear-proof manner by means of a screw 11 ′.
  • a pipe 40 in addition to the second profile 10, is inserted in a hollow chamber between the second profile 10 and the first profile 2.
  • the leg 36 is held on the first profile 2 so as to be linearly displaceable.
  • a web 34 engages in a groove, in particular an undercut groove, on the first profile 2.
  • FIG. 5 A modified embodiment of a composite profile is shown in which the second profile 10 has two legs 31 and 36 as in the previous embodiment, the leg 31 being fixed to the first profile 2 by a screw 11 ′′.
  • the second leg 36 On the second leg 36 are integral Web 32 are formed which engage in an undercut groove on the first profile 2, which has hook-shaped webs 28.
  • the first profile 2 thus has an undercut groove on both sides, the screw 11 ′′ on the first leg 31 for shear-proof fixation and a clamping screw 33 is provided on the second leg 36, which provides for a displaceable guidance of the second leg 36 on the first profile 2.
  • FIG 6 Another embodiment of a first profile 2 is shown, in which a second profile 10 is fixed, which has a central section 30 and two legs 31 and 36.
  • the leg 31 engages with webs 32 in an undercut groove with angular webs 28, the webs 28 and 32 being pressed together in order to produce a shear-proof connection.
  • On the opposite side of the leg 36 is provided with webs 32 which engage in an undercut groove with hook-shaped webs 28, the leg 36 being displaceably guided on the groove.
  • Ribs 35 are formed integrally with the middle section 30 of the second profile 10 and position a tube 40 in the hollow chamber between the first profile 2 and the second profile 10.
  • the composite profile 1 according to the invention is preferably used as a frame profile in an element facade. It is of course also possible to use the composite profile in windows, doors or in post-and-beam constructions.
