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 separation between two metal profiles.
the thermal separation is usually effected via an insulating plastic profile.
For 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 present invention is therefore based on the object of specifying a metal profile for producing a composite profile, which can be connected in a simple manner with an insulating profile non-positively and / or positively.
the metal profile should also ensure a stable bond between the metal profile and the insulating profile.
the proposed metal profile has been produced from a sheet metal by forming, in particular by roll forming.
the metal sheet may be, for example, 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, which lie on each other at least in a common contact area.
the metal sheet of the metal profile has a sheet thickness which is reduced at least in the region of a profile section delimiting the groove.
the area with reduced sheet thickness has a lower flexural rigidity, so that a predetermined bending point is created.
the predetermined bending point facilitates the production of a non-positive and / or positive connection of the metal profile with an insulating profile, since the force required for plastic deformation is less.
the deformation is controlled controlled feasible. Because the deformation is essentially limited to the region of the predetermined bending point, so that lying outside the predetermined bending areas areas no deformation, in particular no plastic deformation subject. Accordingly, a composite profile produced using a metal profile according to the invention has a high mechanical stability, since unwanted plastic and / or elastic deformations do not impair the force and / or form fit. Furthermore, such a composite profile produced by a high dimensional accuracy or dimensional accuracy is characterized.
the sheet metal thickness of the metal sheet is preferably reduced by at least 10%, at least in the area of a profile section delimiting the groove. By this measure, a clearly defined predetermined bending point is created. This applies in particular if subsequent groove-limiting profile sections have no sheet thickness reduction.
the sheet thickness of the metal sheet used to produce the metal profile is preferably 1-3 mm, more preferably 1-2 mm, for example, 1.5 mm. In the areas in which the sheet thickness is reduced by at least 10%, the metal sheet thus has a plate thickness which is between 0.9 and 2.7 mm and between 0.9 and 1.8 mm. For example, with a starting sheet thickness of 1.5 mm, the reduced sheet thickness may be 1.3 mm.
the sheet thickness of the metal sheet is preferably reduced at least in the area of a profile section forming a groove base.
the predetermined bending point is therefore preferably in the region of the groove bottom. That is, in an area furthest from the opening of the groove and / or facing the opening of the groove.
the predetermined bending point acts in this case as a kind of joint around which the adjoining groove-limiting profile sections, which serve primarily the lateral boundary of the groove, can be pivoted. This has the advantage that the predominantly the lateral boundary of the groove serving profile sections need not be deformed to produce the desired force and / or positive connection with an insulating profile.
the groove base may be formed from one or more profile sections.
the at least one profile section forming the groove base can have a reduced sheet thickness only in regions or over its entire length in order to form the predetermined bending point.
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. In a substantially triangular or trapezoidal cross-sectional shape expands preferably the groove in the direction of its opening to facilitate the insertion of an insulating profile in 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 non-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 adjoining the groove-limiting profile sections and at least in a common contact area superimposed profile sections are connected in at least one area, in particular welded or glued.
the connection in particular welding or Bonding, increases the stiffness 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.
the profile sections adjoining the groove-limiting profile sections and resting on one another at least in a common contact area delimit a gap open towards the groove outside their common contact area.
the gap open towards the groove has several advantages.
a first advantage is the fact that the gap facilitates the connection of the gap defining profile sections. If the connection is made by welding, the gap facilitates setting the weld. In addition, the weld seam is able to outgas more easily since it is largely surrounded by air. The lighter outgassing in turn counteracts the formation of voids, which can significantly affect the quality of a weld.
the gap can be used to receive the adhesive.
a low-viscosity liquid adhesive this can even be introduced into the gap, if the force and / or positive connection of the metal profile is already made with an insulating profile.
connection of the gap limiting profile sections is therefore preferably formed in the region of the gap, which further preferably has a gap width of at least 0.4 mm.
the gap can also be used to compensate for elastic deformation components. Because through the gap open towards the groove, a free space is created, which allows a "overpressure" of the groove-limiting profile sections in the production of the force and / or positive connection. In the case of "overpressing", the groove-limiting profile sections are beyond that for producing the non-positive and / or positive connection required amount deformed to compensate for the included elastic deformation component. If, after deformation due to the elastic deformation component, a partial return of the groove-limiting profile sections, this is harmless with regard to the desired force and / or positive connection.
Another advantage of the groove open to the groove is that it 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 profile sections delimiting the gap may also have a reduced sheet thickness in regions. This measure alone already has a gap-forming effect, so that the expense for producing the gap is low.
the sheet thickness reduction is preferably carried out in one operation with the sheet thickness reduction in the region of at least one groove-limiting profile section. Furthermore, these regions preferably adjoin one another, so that the expense for producing the gap is further reduced.
the profile sections adjoining the groove-limiting profile sections and resting on one another at least in a common contact region form a web which is arranged centrally with respect to the groove. If the profile sections further define a gap open towards the groove, this also is arranged centrally with respect to the groove.
the web gives the metal profile a greater depth and consequently a higher stiffness in the depth direction. The depth is measured perpendicular to the length and width of the metal profile.
the profile sections adjoining the groove-limiting profile sections and lying on one another at least in a common contact region are preferably connected via further profile sections.
the further profile sections form at least one flange, which is further 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 stiffness of the metal profile is increased even further.
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, in order to form a profile section delimiting the groove, the sheet thickness of the metal sheet prior to forming, in particular roll forming, is reduced at least in one area.
a metal sheet is used to produce the metal profile, the at least two different Has sheet thicknesses.
At least one groove-limiting profile section is formed from a region with a reduced sheet thickness, so that at least one predetermined bending point is created in the region of the groove or the groove-limiting profile sections.
the sheet metal thickness of the metal profile is reduced even before the forming, in particular roll forming, expensive post-processing steps for forming a predetermined bending point can be omitted. Furthermore, it is ensured that the metal profile produced by forming, in particular roll forming, subsequently experiences no undesirable deformation. Because this would affect the dimensional accuracy of the metal profile.
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 in at least one area by plastic deformation, in particular by stretching.
plastic deformation in particular by stretching.
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 the insulating profile 2, since the region of the fold 6 can be placed around an end outer contour of the insulating 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.
Fig. 2 can be seen, the metal sheet of the metal profile 1 in the region of the groove bottom forming profile sections 3.2, 3.3 a comparison with the sheet thickness S reduced sheet thickness S 'on.
the reduced sheet thickness S 'in the present case is 1.3 mm, while the sheet thickness S is 1.5 mm. Due to the areas with reduced sheet thickness S 'predetermined bending points are created, which facilitate a non-positive and / or positive connection of the metal profile 1 with an insulating profile 2. For one thing, the force required to produce the desired force and / or positive locking by plastic deformation decreases.
the plastic deformation can be essentially limited to the region of the predetermined bending points, so that the groove 3 laterally delimiting profile sections 3.1, 3.4 is not plastically deformed become.
a composite profile can be achieved, which has a high dimensional accuracy.
a reduced sheet thickness S ' also have the web 5 forming profile sections 5.1, 5.2 in the region of the gap 8. Since the gap 8 a weld 10 is arranged, which connects the two profile sections 5.1, 5.2, it is ensured that these two profile sections 5.1, 5.2 are not subject to deformation when the metal section 1 with an insulating profile 2 is non-positively and / or positively connected by plastic deformation. The weld 10 also prevents unwanted bending of the groove. 3
a preferred embodiment of a composite profile produced using a metal profile 1 according to the invention is the Fig. 3 refer to.
the composite profile comprises the metal profile 1 of Fig. 1 and a second metal profile 1, which differs from the first metal profile 1 only in that it has a flange 9 with a smaller width.
an insulating profile 2 is arranged between the two metal profiles 1. At its two ends, the insulating profile 2 each has an outer contour, which is received in the groove 3 of the respective metal profile 1 and connected to this force and / or positive fit.
a window or door element is exemplary in the Fig. 4 shown.
a filling element 12 which in the present case consists of a glass pane
sealing profiles 11 are provided for receiving a filling element 12, which in the present case consists of a glass pane.
the sealing profiles 11 are arranged in the region of the web 5 and supported on the flange 9.
Further sealing profiles 11 are placed on glass holding profiles 13, which are arranged on both sides of the second metal profile 1.
the glass retaining profiles 13 terminate substantially flush with the flange 9 of the second metal profile 1 and the width thereof is selected such that the face width of the second metal profile 1 including the glass retaining profiles 13 corresponds to the face width of the flange 9 of the first metal profile 1.
