Definitions

• the present invention relates to a composite profile for a window or a door or a facade element, a frame and a method for manufacturing a composite profile for a door or a window or a facade element, in particular with fire protection properties.
• State-of-the-art composite profiles typically consist of a first profile – usually an outer profile – and a second aluminum profile – usually an inner profile – which are connected by at least one heat-transfer-reducing element, such as an insulating profile, which may be made of a less conductive material like plastic.
• the composite profiles from the outside in – referring to an example installation situation in an exterior wall — have three or more aluminum profiles and two or more insulating profile zones.
• interior use — which is also conceivable – one space can be considered the exterior and the other the interior.
• an aluminium profile is a profile that has been manufactured from aluminium or an aluminium alloy.
• the composite profiles are particularly suitable – but not exclusively – for the manufacture of fire-resistant doors or windows, which are then preferably suitable for at least fire resistance class T30 or F30 according to DIN 4102-13 and DIN EN 16034 for exterior applications, i.e., for installation in external firewalls of fire resistance class EI 2 30-S a C2.
• they can also be used in doors, windows, or facade elements that are not intended for exterior applications.
• fire-resistant walls are designed and/or used in the interior of buildings.
• Fire protection structures made of thermally broken profile constructions have also been known for a long time.
• a fire-resistant profile system is described, consisting of an aluminum profile with a central section where heat flow to the outer areas is reduced by cutouts, such as punched holes.
• cutouts such as punched holes.
• a disadvantage of such fire-resistant constructions is that they can warp in the event of a fire (i.e., due to temperature differences between the inside and outside) (bimetallic effect).
• two aluminum profiles are generally provided, each having at least one (or more) undercut groove(s) in its main extension direction, into which corresponding foot sections of an insulating profile made of plastic can be inserted. After this insertion, an edge rib of the grooves of the aluminum profiles, usually called an anvil, is rolled onto the insulating profile.
• a composite profile is to be created that exhibits very good structural properties, preferably enabling its use in fire protection applications. Furthermore, the invention aims to simplify the corresponding manufacturing process as much as possible.
• the present invention solves this problem by means of the composite profile of claim 1. It also provides the frame of claim 14, the window or door according to claim 15 and the method of claim 16. Advantageous embodiments of the invention are specified in the dependent claims.

• the fastening areas are rolling areas. It is particularly advantageous, simple, and improves the statics that the rolling areas on the aluminum profile comprise grooves into which corresponding foot sections of the insulating profile engage.
• the statics are further positively influenced by the fact that the foot sections are fixed in the grooves perpendicular to the main direction of extension in a tensile-resistant manner. It can be advantageously provided that the grooves are fixed in the grooves perpendicular to the main direction of extension by at least one means that increases the tensile strength.
• the respective grooves are designed as undercut grooves into which the corresponding foot sections engage in a tongue-and-groove joint, wherein the grooves widen continuously or section by section from an opening area towards their base, and wherein the foot sections widen correspondingly towards their ends, so that the foot sections are fixed in the grooves perpendicular to the main direction of extension in a tensile-resistant manner by these means.
• the grooves in a section perpendicular to the main extension direction are open exactly or substantially in the opposite direction, and that the corresponding foot sections of the insulating profile, pointing exactly or substantially in opposite directions, engage in these grooves, wherein the foot sections are fixed in the grooves parallel to the main extension direction or in this main extension direction and against this direction in a shear-resistant manner.
• the foot sections are fixed in the grooves parallel to the main direction of extension by means of a means that increases shear strength.
• This means can, for example, be formed by a knurled wire or the like running parallel to the feet in the grooves, or by another means such as a projection on one of the groove webs (e.g., on the groove web called the anvil), which is pressed into the insulating profile when rolled against it.
• the aluminum webs run at least partially alongside the insulating profile, in particular parallel and transverse or oblique to the insulating profile. In this way, the static properties of the composite profile are particularly good. It can even be provided that the webs run at least partially parallel to the insulating profile and support it.
• the recesses are covered on one side by the insulating profile.
• the insulating profiles and the aluminum webs are at least partially corresponding in a c-shape and preferably lie adjacent to each other in sections.
• the preferred material is a prefabricated aluminum profile, simply designed as a one-piece extruded profile made of aluminum or an aluminum alloy, to which the single insulating profile is attached.
• the cutouts can be rectangular or trapezoidal, for example.
• good thermal insulation and good statics are further advantageous if the grooves are each supported by one or more wall sections of the aluminium profile, wherein one of these wall sections runs approximately perpendicular to the respective base wall of the respective groove and wherein the other of these wall sections runs approximately in extension of one side wall of the respective groove at an angle - preferably at an angle between 20° and 70°.
