Definitions

  • the present invention relates to a composite profile, preferably a thermally insulated composite profile, in particular in a fire protection version, according to the preamble of claim 1 as well as a sash or window frame for a door, a window or a facade element and a method for producing the composite profile.
  • Smoke protection doors according to DIN 18095 are self-closing doors that largely prevent the passage of smoke when installed and closed.
  • a fire protection barrier on the other hand, has the additional task of protecting openings in walls against the passage of fire.
  • the profiles or sections of profiles which are usually produced by an extrusion process or an extrusion process or a roll forming process, as well as the connecting webs each have joining surfaces in the form of a tongue-and-groove connection, which are used to join profiles, in particular metal profiles. and from insulating webs designed as connecting webs to composite profiles.
  • the respective joining surfaces of the profiles and the connecting bars must be provided with coordinated tolerances so that the profiles and the connecting bars can be pushed into one another during assembly.
  • a profile area that can be plastically deformed - usually a web-like projection, hereinafter also referred to as a foot - is then plastically deformed by a so-called rolling process in such a way that a positive and non-positive connection is achieved - i.e. a shear-resistant composite - is created between the respective profiles and connecting webs and a composite profile is formed.
  • the profiles and connecting webs to be connected to one another can be made from different materials, such as metal or plastic or combinations of materials.
  • At least two profiles are used, which form a composite profile, but composite profiles are known that consist of more than two individual profiles.
  • a preferred embodiment, particularly for fire protection structures consists of two light metal, in particular aluminum, profiles, which are connected to one or more connecting webs or insulating webs.
  • two light metal profiles, in particular aluminum profiles are connected to one or more connecting webs made of plastic, whereby the plastic webs can be provided with metallic bridge sections.
  • the bridge sections from a more heat-resistant plastic than the remaining connecting webs, which can then be made of polyamide, for example.
  • the webs then preferably have recesses.
  • outer functional grooves and inner grooves for receiving external threads mean that the relative length of the connecting webs, which essentially defines the width of the space between the metallic profiles, is limited or relatively short.
  • the state of the art with regard to connecting devices and connecting methods for composite profiles includes: DE 30 25 706 A1 , the EP 0 311 850 A2 , the EP 2 163 719 A2 as well as the WO8403326A1 .
  • the DE 30 25 706 A1 shows a device for rolling or connecting profiles and connecting webs.
  • the DE 30 25 706 A1 further shows that the roller tools for forming the deformation bars - require a considerable amount of space. This means it is not possible to get above the hammers - so Arrange further functional grooves in the area in which the roller tools are used when assembling the composite profile.
  • Such functional grooves can therefore only be positioned laterally next to the space required for the roller tools. This limits the width of the connecting webs or the entire composite profile must be made wider in order to integrate connecting webs with a longer cross-section, which would have improved thermal insulation properties.
  • the hammers are in the EP 0 311 850 A2 pressed or rolled approximately at right angles onto the connecting bars.
  • a hammer is rolled in the same plane or parallel to the connecting bar.
  • the EP 2 163 719 A2 describes a common and well-proven assembly method for composite profiles.
  • several pairs of rollers each with different roller diameters, are used.
  • the rollers are used in pairs so that each can apply an appropriate counterforce.
  • three, four or five of these pairs of rollers are arranged directly one behind the other on an assembly device.
  • This method is pronounced of a rolling process on a rolling train with several rolling stands, in which each rolling stand of the rolling train contributes a defined, discrete amount to the desired overall thickness reduction of the rolling stock.
  • the rollers usually have a structure on their circumference, for example a corrugation, in order to be able to transmit feed forces to the composite profile in addition to the forming forces.
  • the parts of the composite profile are connected to one another in one operation and pushed or pulled through the assembly tools.
  • rollers often have a shoulder so that they can roll over existing side grooves without undesirably deforming and thus damaging the profile or grooves.
  • a paragraph otherwise has no further function for the composite profiles.
  • the WO8403326A1 discloses that the hammer can also have a web with a structured cross-sectional geometry, so that this hammer not only presses on the connecting web at a 90 ° angle, but additionally forces are also applied in the direction parallel to the connecting web. Also reveals the WO8403326A1 that the rollers can have beveled peripheral sides, so that in addition to radial forces, axial forces also become effective on the roller circumference during the rolling process.
  • DE2755669B1 discloses a composite profile for a frame or a casement of a window, a door or a facade element.
  • DE202007016649U1 also discloses a composite profile.
  • FR2411950A1 and EP0765989A1 disclose a method for producing a composite profile.
  • the object of the present invention is to create a preferably thermally insulated composite profile, in particular in a fire protection version, for the production of casement and/or frames for doors, windows or facade elements, which at least partially overcomes the disadvantages of the prior art.

  • the first groove wall can be designed as a side wall or as a longitudinal leg of the preferably U-shaped first groove.
  • the second groove has a groove opening which is arranged above or below the foot of the insulating bar when the insulating bar is imaginary horizontally aligned.
  • the insulating bar can also be aligned vertically in a composite profile, depending on the orientation, for example in the window or door frame.
  • the horizontal alignment of the composite web discussed here therefore only refers to an imaginary installation position and serves to define the position of the groove opening in relation to the composite web in this exemplary installation position.
  • the first groove wall or the second groove wall has at least one projection or a series of projections. This projection protrudes into the first groove.
  • the projection should therefore not be confused with the edge of the groove opening.

  • the change, preferably reduction, of the cross section or the width or width of the groove opening of the first groove can take place until a contour of the final composite profile according to the invention is reached, in which the foot and thus the insulating web can no longer be removed from the first groove. In this way, a tongue-and-groove connection is easily formed, which lies directly below another groove.
  • the respective foot of the insulating web (also known as a connecting web) can be fastened in this way, although it also lies directly below a second groove.

  • a disadvantage of the methods mentioned in the prior art is that complex profile geometries could not be deformed using the previously known methods. Most of the time, relatively simple hammers are used that have no other functions besides their actual function as a deformable connecting and holding element.
  • the present method allows the relative width of the connecting webs to be increased in relation to the overall width of the respective composite profile.
