Definitions

  • the invention relates to a metal profile with the features of the preamble of claim 1.
  • the metal profile should be particularly suitable for producing a composite profile that can be used in the construction sector as a window, door or façade profile.
  • the invention relates to a composite profile with such a metal profile and a method for producing the metal profile.
  • metal profiles for the production of windows, doors or facade construction is well known.
  • Metal profiles, especially steel profiles, have the advantage that they have a high dimensional stability and consequently can absorb high loads.
  • the relatively high thermal conductivity of the material metal proves to be disadvantageous. Therefore, measures must be taken to ensure the required thermal protection.
  • One measure may be to provide a thermal break.
  • the thermal separation is usually effected via an insulating profile made of plastic, which is arranged between two metal profiles.
  • plastic has a much lower thermal conductivity compared to metal.
  • thermally separated profiles are also called composite profiles, as at least one metal profile and an insulating profile are non-positively and / or positively connected. The connection must be such that a sufficiently stable bond is ensured.
  • the profile sections forming the lateral boundaries of the fastening groove are connected via further profile sections which describe a profile loop which comprises profile sections adjoining each other at least in one region and are connected with each other in the area of their adjacency.
  • these are profile sections of the profile loop, which adjoin directly to the profile sections forming the lateral boundaries of the fastening groove.
  • the connection is preferably by means of a weld.
  • the present invention seeks to provide a metal profile, the non-positive and / or positive fit with an insulating profile for producing a composite profile is connectable and ensures a stable bond in this arrangement. Furthermore, the metal profile should be simple and inexpensive to produce.
  • the proposed metal profile has been produced from a sheet metal by forming, in particular by roll forming.
  • the metal sheet may in particular be a sheet of steel, stainless steel, copper or a copper alloy.
  • the metal profile has a groove forming a profile cross-section.
  • the groove is bounded by profile sections, connect to which profile sections that lie in a common contact area to each other. According to the invention, it is provided that the profile sections lying on top of one another, outside their contact area, delimit a gap open towards the groove.
  • the gap which is open towards the groove, creates a free space which has several advantages.
  • the free space promotes the removal of media, in particular oils, which are used regularly before and / or during the forming to protect the surfaces of the workpiece and / or the tools.
  • the metal profile produced by forming according to the invention thus tends less to "bleed" and can be further processed accordingly faster.
  • the clearance created by the gap can be used to receive a weld or an adhesive to connect the two gap-limiting profile sections.
  • the dimensional stability of the metal profile can be increased.
  • the risk of undesired bending of the groove is reduced, so that a permanently stable bond between the metal profile and an insulating profile is ensured.
  • the clearance created by the gap facilitates the setting of the weld seam. Because the accessibility is improved by the gap. Furthermore, a weld arranged in the gap can more easily vent, thus counteracting the risk of the formation of voids. This improves the quality of the weld.
  • connection of the gap limiting profile sections should be effected by a bond, created by the gap clearance for receiving the adhesive can be used, the introduction of the adhesive, especially when using a low-viscosity liquid adhesive, both before and after the force - And / or positive connection of the metal profile can be done with an insulating profile.
  • the subsequent bonding of the gap limiting profile sections also has several advantages.
  • a first advantage is the fact that the gap - until the introduction of the adhesive - expands the groove.
  • the production of a non-positive and / or positive connection of the metal profile with an insulating profile can thus be effected with less effort.
  • the profile sections delimiting the gap extend the lever arm, which is formed by the groove-limiting profile sections arranged on both sides of the groove, so that the force required for deformation is lower according to the law of levers. In this way, the gap facilitates the production of a non-positive and / or positive connection between the metal profile and an insulating profile.
  • Another advantage is the fact that the space created by the gap allows "overpressing" at least one groove-limiting profile section to produce a non-positive and / or positive connection between the metal profile and the insulating profile.
  • the at least one groove-limiting profile section is deformed beyond the extent required for producing the positive and / or positive-locking connection. If, subsequently, due to an additional elastic deformation, the profile section partially returns, the partial return is harmless for the force and / or positive connection to be achieved. Because of the partial provision causing elastic deformation component is compensated by the initial "overpressure".
  • the gap which is open towards the groove therefore initially lowers the dimensional stability of the metal profile.
  • the initially lower stiffness can - as described above - have an advantage.
  • a permanently stable bond between the metal profile and the insulating profile should be ensured by the highest possible dimensional stability of the metal profile.
  • the profile sections delimiting the gap are connected, preferably welded or glued, in the region of the gap. Because the connection of the two profile sections leads to the desired high dimensional stability of the metal profile. In particular, it counteracts an undesirable bending of the groove after the force and / or positive connection has been made with an insulating profile.
  • a weld seam for connecting the profile sections delimiting the gap is arranged.
  • the weld can be a laser weld, since laser welds can be carried out particularly precisely.
  • the gap also facilitates the setting of the weld. This applies in particular if - as proposed - the weld is arranged in the region of the groove towards the open end of the gap. Because this area is easily accessible via the groove. That is, the weld is preferably disposed in a region forming a groove bottom of the groove. With a corresponding arrangement of the weld also a particularly effective protection against undesired bending of the groove is effected.
  • the sheet thickness of the metal sheet from which the metal profile is made, at least in the region of a gap limiting profile section is reduced.
  • the area with reduced thickness can then be used to form the gap.
  • training the gap brought two areas with reduced sheet thickness in coverage, so that a larger gap width can be achieved.
  • the regional reduction of the sheet thickness is preferably achieved by plastic deformation, in particular by stretching, of the metal sheet.
  • stretching a possible coating of the metal sheet, such as serving as a rust-proof zinc coating, basically preserved, so that further effective rust protection is guaranteed.
  • the sheet thickness of the metal sheet for the production of the metal profile is 1-3 mm, further preferably 1-2 mm, for example 1.5 mm.
  • the sheet metal thickness of the metal sheet is reduced by at least 10%, at least in the area of a profile section delimiting the gap. Because this allows the formation of a sufficiently wide gap. If, for example, a metal sheet with a sheet thickness of 1.5 mm is used to produce the metal profile, the gap width is preferably at least 0.4 mm.
  • the groove is formed symmetrically in cross section.
  • the required for producing a composite profile non-positive and / or positive connection of the metal profile with an insulating profile can be effected in this case by uniform pressing or compression of the groove-limiting profile sections.
  • the groove has a substantially triangular, trapezoidal or rectangular cross-sectional shape.
  • the groove preferably widens in the direction of the opening to facilitate the insertion of an insulating profile into the groove.
  • the cross-sectional shape of the groove can change.
  • an originally trapezoidal groove may subsequently have a rectangular cross-sectional shape.
  • the cross-sectional shape of the groove of a metal profile according to the invention essentially depends on whether a positive and / or positive connection with an insulating profile has already been produced or not.
  • the groove have laterally delimiting profile sections at their free ends a curl or a fold.
  • a higher rigidity of the free ends of the groove laterally limiting profile sections is achieved because here the material is double or at least has a stiffening profiling.
  • the region of the curl or the fold simplifies the production of a positive connection, since it can be laid around an outer contour of an insulating profile such that it engages behind it.
  • At least one profile section delimiting the groove has a groove-side surface which is provided at least in regions with a structuring, for example in the form of a knurling.
  • the structuring counteracts a relative movement of the insulating profile received in the groove in relation to the metal profile in the transverse and / or longitudinal direction (thrust direction). Such relative movements are undesirable because they affect the bond between the metal profile and the insulating profile and reduce the mechanical strength of the composite profile as a result.
  • the gap defining profile sections form a web, which is preferably arranged centrally with respect to the groove.
  • the bridge gives the metal profile a greater depth and consequently a higher dimensional stability in the depth direction. The depth is measured perpendicular to the length and width of the metal profile.
  • the profile-limiting profile sections are preferably connected via further profile sections.
  • the further profile sections form at least one flange, which is furthermore preferably arranged perpendicular to the web.
  • a flange can serve the formation of a stopper, which is to be formed regularly on a window or door profile.
  • a flange can be used to form a lateral groove into which a sealing profile or the like can be inserted.
  • the further profile sections can also lie on one another at least in regions in the area of a flange. Alternatively, however, the further profile sections can also delimit a cavity, as a result of which the dimensional stability of the metal profile, in particular due to the greater depth, is increased again.
  • the metal profile according to the invention primarily serves to produce a composite profile
  • a composite profile with at least one metal profile according to the invention is also proposed.
  • the proposed composite profile also includes an insulating profile, which is partially received in the groove of the metal profile and non-positively and / or positively connected to the metal profile.
  • the proposed composite profile is characterized by a stable bond and a high dimensional stability. Both are due to the use of at least one metal profile according to the invention.
  • the composite profile comprises at least two metal profiles according to the invention, which are thermally separated by the insulating profile.
  • the insulating profile is arranged for this purpose between the two metal profiles.
  • the cross-sectional shape of the two metal profiles may be formed differently, but both metal profiles have a groove forming a profile cross-section for receiving the insulating profile.
  • the insulating profile preferably has at least one end on an outer contour, which allows engaging behind a profile section of a metal profile.
  • a method for producing a metal profile according to the invention in which the metal profile is produced by forming, in particular roll forming, from a metal sheet.
  • the method is characterized in that the plate thickness of the metal sheet before forming, in particular roll forming, is reduced in at least one area in order to form the gap.
  • a metal sheet having at least two different sheet thicknesses is used to produce the metal profile.
  • the use of such a metal sheet simplifies the formation of the gap open towards the groove, since the sheet thickness reduction automatically acts gap-forming when two profile sections are laid one on top of the other. This is especially true if not only a gap-limiting profile section partially has a reduced sheet thickness, but both have opposite to the gap profile sections a sheet thickness reduction.
  • the areas with reduced sheet thickness of the respective profile sections during forming, in particular roll forming need only be brought into overlap.
  • the sheet thickness of the metal sheet which is preferably 1-3 mm, more preferably 1-2 mm, for example, 1.5 mm, is reduced by plastic deformation, in particular by stretching, in at least one area.
  • plastic deformation in particular by stretching, in at least one area.
  • any existing coatings of the metal sheet for example, serving as a rust-proof zinc coating, largely retained, so that further an effective rust protection is guaranteed.
  • stretching involves a reduction in coating thickness, in the case of a zinc coating, this has the advantage that it no longer needs to be removed to set a weld.
  • the method for producing a metal profile according to the invention can be further simplified.
  • a metal sheet which is provided with a zinc coating, it is preferably a continuous hot dip coated (previously: strip galvanized) steel sheet.
  • the sheet thickness of the metal sheet is reduced in at least a range by at least 10%. Based on the above-mentioned preferred sheet thicknesses, therefore, the reduced sheet thickness is between 0.9 and 2.7 mm or between 0.9 and 1.8 mm. With a starting sheet thickness of, for example, 1.5 mm, the reduced sheet thickness can be 1.3 mm.
  • the sheet thickness reduction can be formed both symmetrical and asymmetrical.
  • Metal profile 1 shown in cross section has been produced by forming from a metal sheet and has a substantially T-shaped profile cross-section.
  • the two ends of the metal sheet thereby form lateral boundaries of a groove 3, which in the present case is trapezoidal in cross section.
  • the trapezoidal cross-section of the groove 3 facilitates the insertion of an insulating profile 2 in order to form a composite profile according to the Fig. 3 or the Fig. 4 to get.
  • the groove 3 laterally bounding profile sections 3.1, 3.4 are folded at their ends to form a groove-side fold 6.
  • the fold 6 facilitates the production of a positive connection between the metal profile 1 and an insulating profile 2, since the region of the fold 6 can be placed around an end-side outer contour of the insulating profile 2, that the fold 6 engages behind the outer contour.
  • the groove 3 limiting profile sections 3.1, 3.2, 3.3, 3.4 in the Fig. 1 illustrated metal profiles 1 have on their nut rocken surface structuring 7 in the form of a knurl (see dashed line, which should clarify the range of knurling).
  • the knurling counteracts relative movements of a groove 3 received and non-positively and / or positively connected with the metal profile 1 insulating profile 2 against the metal profile 1.
  • the groove 3 limiting profile sections 3.1, 3.2, 3.3, 3.4 include the profile sections 3.2, 3.3, which form a groove bottom of the groove 3.
  • the regions, namely in a common contact area 4 lie on each other and thus form a web 5.
  • the profile sections 5.1, 5.2 delimit a gap 8, which is open to receive a weld seam 10 towards the groove 3 (in FIGS Fig. 1 and 2 the metal profile 1 is already shown with set weld 10).
  • profile sections 5.1, 5.2 close to further profile sections 9.1, 9.2, 9.3, which form a flange 9, which are arranged perpendicular to the web 5.
  • profile sections 9.1, 9.2, 9.3 are also adjacent to each other, so that a high dimensional stability is achieved by the double-lying material.
  • the metal sheet of the metal profile 1 in the region of the gap 8 limiting profile sections 5.1, 5.2 a reduced sheet thickness S 'on.
  • the sheet thickness reduction automatically leads to the formation of the gap 8.
  • the sheet thickness S is 1.5 mm.
  • the metal sheet has a sheet thickness S 'of 1.3 mm. Since the sheet thickness reduction has been carried out asymmetrically, it benefits entirely the gap formation, so that the width B of the gap 8 is 0.4 mm.
  • the length L of the gap 8 is presently 4 mm.
  • the Fig. 2 is still clearly apparent in the gap 8 arranged weld 10.
  • the arrangement of the weld 10 takes place in the region of the groove bottom of the groove 3, so that the weld 10 is particularly effective counteracts undesirable bending of the groove 3.
