Definitions

  • the present invention relates to a metal profile with at least one cross-section determining bend, in particular for the production of frame structures for window, door partition or facade elements, according to the preamble of claim 1. Furthermore, the present invention relates to a method for producing such a metal profile.
  • frame structures are used for the bordering of panel or glass elements, for example to form casements or to serve as part of a facade.
  • frame structures of interest here usually consist of metal profiles, preferably steel or a light metal is used.
  • the metal profile is usually formed by forming a homogeneous flat profile; Occasionally, the metal profile made of steel is also produced as a welded construction.
  • the metal profile is made of a light metal, it is usually produced by extrusion (extrusion).
  • the window, door or façade elements of interest here are used at the boundary point inside to outside on a building, it is not only necessary that the insert elements are thermally insulated; Also, the metal profile itself is to be designed so that this prevents heat transfer inside to outside or vice versa as possible.
  • thermally insulated metal profile which consists essentially of an inwardly directed upper part, an outwardly directed lower part and connecting these side walls. Overall, results in an approximately rectangular cross-sectional shape.
  • the side walls have inclined webs. Furthermore, the side walls are designed such that their height is less than or equal to the distance between the end walls of the upper part and lower part. Furthermore, the side walls are welded here with the upper part and the lower part.
  • the top and bottom parts to be formed are first to be produced, after which the side walls can be attached thereto by welding, so that overall the rectangular cross-sectional shape is created.
  • the production of this known metal profile proves to be quite expensive. In particular, the individual components to be machined in the initial production steps are then quite expensive to assemble by means of welding devices and the like.
  • the object is achieved on the basis of a metal profile according to the preamble of claim 1 in conjunction with its characterizing features.
  • the invention includes the technical teaching that the cross-section of the metal profile determining at least one bend is formed by cold forming a flat composite profile strip, which consists in cross section of several interconnected by form or material connection sections of different materials and / or different thicknesses.
  • the advantage of the solution according to the invention lies, in particular, in the fact that, for example, a frame profile of the form explained above with reference to the prior art can be produced by means of a single forming step sequence and joining technique without the need for subsequent other production steps.
  • the metal profile according to the invention is angled several times such that preferably the relatively thick portions form the upper and lower part of the metal profile, whereas the relatively thin portions form the side walls of the metal profile.
  • the relatively thick portions form the upper and lower part of the metal profile
  • the relatively thin portions form the side walls of the metal profile.
  • they may additionally consist of other materials or stainless steel and the like. Since stainless steel has a higher strength than the structural steel normally used, so different thickness ratios can be compensated by different choice of materials. If the side walls of the metal profile are now made of stainless steel, they also have a lower thermal conductivity per se because of the smaller thickness per se.
  • the invention with regard to an additional reduction of the thermal conductivity improving measure is provided that are provided on at least one of the outer surfaces, according to the above-described embodiment, on both side walls, punched openings.
  • These breakthroughs may for example have the shape of a parallelogram, triangle, slot and the like and are preferably produced by non-cutting punching.
  • the composite profile strip 1 which is flat in the initial shape, is composed of individual sections 2a-2e in such a way that a continuous surface results on the one side 3.
  • the sections 2a, 2c and 2e of greater thickness here consist of structural steel, whereas the others here are alternate sections 2b and 2d made of stainless steel.
  • the connection of the individual sections 2a-2e with each other is done by a material fit by welding. Overall, a mechanical stable composite material results.
  • the composite profile strip 1 is processed in a first manufacturing step prior to forming in a non-cutting manufacturing process.
  • openings 4 are introduced into the section 2e by punching.
  • the metal forming is then carried out to the metal profile shown here, in which the composite profile strip 1 is shaped by cold forming in such a way that the desired profile results.
  • Cold forming takes place here by roll forming.
  • the openings 4 are used in this metal profile minimizing the thermal conductivity.
  • the invention is not limited to the preferred embodiment described above. On the contrary, modifications are conceivable which are encompassed by the scope of protection of the following claims.
  • embossing, deep drawing and the like to the sections of the composite profile strip, in addition to or instead of the openings, preferably before forming.
  • the composite profile strip can also consist of other suitable material combinations, provided that they can be joined together in a form-fitting or material-locking manner in such a way that no cracking or material breakage as a result of forming is to be feared.
  • the profile according to the invention is suitable for producing a variety of frame structures for civil engineering applications, in which it depends in particular on a minimum thermal conductivity combined with high static strength.
