Description

The invention relates to a profile for frames of wall elements, Doors or windows as well as a method of manufacturing the profile having the features of the preamble of the independent claims.

Such profiles are also intended to serve a particular Thermal insulation to ensure the frame construction. A Another possible use is in fire protection.

For example, EP 0 802 300 A2 shows a composite profile two metal profiles and these connecting metal strips, thereby three inner chambers are formed. The metal strips have About cutouts, which form webs, to the reduction the heat flow of the composite profile. EP 0 802 300 A2 further shows that the metal strips having guide grooves Metal profiles are positively connected. Such Composite profile is due to the relatively complicated design and in particular by the nature of the connection of the middle part relatively difficult with the two metal profiles produce and expensive.

DE 195 26 795 describes a composite profile of two spaced metal profiles and one between them located insulating material, wherein the two profiles respectively outwardly directed, approximately U-shaped profiles Welding of metal webs on the respective side surfaces the profiles are interconnected. A metal bridge can thereby also having as a plurality of openings Be formed sidewall. The metal bars or side walls However, they must have an excess length, that is the height of the Metal bars must be larger than the distance between the two Be profiles. This sidewall can only be laterally attached to the profiles can only be attached laterally to the profiles, so at least a part of the side wall protrudes. The handling and the Using such a profile can be difficult. The outside lying the side walls also has a negative effect on one Cover the side walls. Such a composite profile is also from an optical point of view for use with frames of wall elements, doors or windows little suitable.

It is therefore an object of the present invention that To avoid disadvantages of the known, in particular a device and to provide a method of the type mentioned above, which in particular can be created in a simple manner and the production requires as few steps as possible. The profile should on the one hand the lowest possible heat conduction or ensure good thermal insulation and should on the other hand a have high static and dynamic stability. The profile intended as a base profile for profiles and composite profiles for frames wall elements, windows or doors of various applications Find use.

According to the invention, this object is achieved with a profile of the features of the characterizing part of the independent claims.

The profile basically consists of three components: Lower part and these connecting side walls. Top and bottom each contain an end wall. These components exist made of metallic materials, preferably of steel, which have relatively high heat conduction. To the heat conduction through the profile, from the top to the bottom to reduce the side walls are provided with sloping webs. Due to the oblique arrangement of the webs, the webs are covered formed long on the distance from the upper part and lower part.

As a result, the heat transfer through the side walls due Thermal conduction over the webs reduced, or the thermal insulation of the Frame improved. The larger the inclination or the longer the Webs are formed, the higher is always the thermal insulation fail. The side walls are with the top and / or welded to the base. The height of the side walls is less than or equal to the distance between the end walls of the top and bottom. Thus, a profile with a good thermal insulation and with good static properties easy and inexpensive to produce. Such a profile draws Also characterized by it for fire protection or Burglary protection can also be used.

Particularly advantageous, the upper part and / or the lower part at least one parallel to a side wall extending bend for forming a contact surface with a side wall. In the area of the contact surface then the upper part or the lower part welded to the side walls. Such an arrangement makes welding much easier. Because the bend is parallel to a side wall and flat on a side wall rests, The sidewalls can be easily made by laser welding process be connected to the upper part or lower part. The manufacturing costs for a profile can be significantly reduced. This embodiment is particularly well suited for a rational, automatic serial production of a profile.

Preferably, the side walls are arranged inside. The Upper part, the lower part and the connecting side walls form a chamber. Inside is in this context, that the side walls disposed on the side facing the chamber are. This has the advantage that the profile in With respect to the side wall has no protruding parts. There at least part of the side wall is "hidden", meets a such profile higher aesthetic requirements. In addition leaves a side element, such as a plastic strip or simply attach a fire strip to the sidewall, because the side wall is arranged inside the profile, can e.g. Side elements flush with the bends on the side walls be attached.

It is advantageous if the side walls over parallel Have guide grooves. A guide groove can as Serve stop for a second or adjacent profile. Two But parallel to each other running grooves can also for receiving side elements, for example a plastic strip or fire bars are used.

The invention can be realized particularly simply if at least a side wall over each laterally arranged, preferably U-shaped brackets for receiving a side member feature. Such a holder can be about simple Way by a two-sided bending of the side wall be prepared in such a way that in each case to the top and the Lower part of the profile facing sides a U-shaped bracket arises. A shot of a page element is thereby easy and cheap to produce. A bridge can be a longitudinal direction have the bead extending bead. In general, that is Beading designed in the form of an inwardly directed indentation. It is advantageous that the profile higher static Withstand requirements.

The webs may be advantageous as one or more rows of be formed about V-shaped arrangements. A series of about For example, V-shaped arrays of ridges become characterized achieves that in the side walls openings in the form of alternately staggered triangles or trapezoids attached become. Several rows of approximately V-shaped arrangements of webs form a crosswise or X-shaped arrangement. The However, bars do not necessarily have to be attached only arise from openings in the side walls. That's the way it is possible, the bars individually with the top and with the To weld lower part. The basically about V-shaped arrangement The webs has the advantage that the profile is a good one Thermal insulation and good static properties. One additional advantage is that a significant weight saving is possible.

On the side walls panels may be appropriate. A Such cladding has the advantage that the side wall is simple and can be covered inexpensively. Disguises can also have different colors.

If the upper part and the lower part have bends, is It is beneficial if at the bends at its end are arranged inwardly directed end faces. There are the side walls of the profile in the area of the front sides with the Welded upper part and the lower part. The faces are preferably provided with a stop for a side wall, which defines the end of a top or bottom part. The advantageous right-angled or approximately right-angled bends are usually mounted on both sides and run parallel to the side walls. It is important that through the inward End faces on the profile a depression is created in the advantageous manner elements such as fire or cover strips can be attached. The profile thus points in usually no laterally protruding parts. The respectively opposite each other, preferably parallel to the bends extending stops of the front sides of a shell and a lower part form bearing surfaces for each side wall. Next could easily be in the Chamber of the profile respectively upper part and / or in the lower part in the area defined by the faces thermal insulation panels, or in particular fire protection boards are added.

The angle between an end face and a bend of a Upper part or lower part is between 5 ° and 170 °, preferably between 5 ° and 135 °, more preferably between 20 ° and 90 °. By the preferred embodiment and in particular by the particular preferred embodiment of 90 ° or about 90 ° becomes a advantageous recess for receiving side parts such as cover strips or fire protection strips created.

Particularly advantageous form an inwardly directed end face and a stopper a groove for receiving side elements. For upper and lower parts made of sheet metal, for example, the groove particularly easy to be produced by Abkantprozesse. The Groove forms an approximately U-shaped holder for the side elements, where width and depth of the groove of the respective purpose depend on the profile. If for the upper and lower part sheets can be used in metal, so these can easily and manner produced by a bending or roll forming process become.

Particularly advantageous are the side walls with the end faces welded the bends. A weld can thus relatively simply done from the outside.

Alternatively, the side walls with the preferably short welded parallel stops the front sides. The Stops form bearing surfaces for placing the side walls. Due to the welding in the area of the flat bearing surface the welding remains relatively distortion free. Especially advantageous the welds are designed as stitching.

It is advantageous if the upper part and lower part made of steel and the side walls are made of stainless steel. Through the different Steel types, the profile has particularly good thermal insulation properties on, because stainless steel heat is less good than ordinary Steel conducts. The profile is still proportionate inexpensive to produce.

A web of a side wall may be a longitudinal direction of the web have running bead. The bead is as preferably after inside directed, in cross-section approximately semicircular indentation designed. A profile with a bead arrangement points improved static properties.

Another aspect of the invention relates to a profile for frames of wall elements, doors or windows with a shell and a lower part and these connecting side walls, the openings exhibit. On the side walls are in the area of the openings inwardly deformable cams for fixing insulating material intended. Depending on the intended use, one can be used per opening or a plurality of cams may be provided. The shape of the Cam is arbitrary, but they should be proportionate just be deformed inward. With the help of the cams a profile is formed in whose chamber insulation material is arranged, by an advantageous fixation of the insulation material out. Especially with regard to the longitudinal direction of the profile, the insulation material sits firmly in the chamber and Slipping is impossible. Through the cams can also Insulation material, which the chamber of the profile only partially fills and arranged in particular centrally in the region of the side walls is to be fixed in a simple way.

The insulating material is advantageous through the cams positive and / or positive fit in the chamber of the profile held. For example, the insulation material by plastic deformation of the insulating material in this ring mature. But it is also conceivable that the insulation material preformed corresponding Ausspaarungen for recording having inwardly deformable cams. imaginable is also that the cams in addition, inwardly directed claw-like Surveys.

Preferably, a cam is approximately in the middle of the base of a Opening arranged. Basis forms the part of the Opening which runs in the longitudinal direction of the profile. Advantageous with this arrangement of cams, the cams are up in a statically favorable location and the cams are efficient and can be easily pushed in.

Insulation material can be arranged in the area of the side walls be, whereby an upper and lower chamber is formed. The Insulation element is preferably approximately rectangular in cross section. These two chambers may also vary depending on the application with insulation material, fire protection elements or similar be filled. The approximately central arrangement of the insulation material leads to particularly good thermal insulation properties of the Profile.

Another aspect of the invention relates to a method for Producing a profile for frames of wall elements, doors or windows with a top, a bottom and these connecting Sidewalls, where the sidewalls webs to improve the thermal insulation properties of the profile and cams for fixing of insulation material. For fixing the insulation material, which is arranged in the chamber of the profile is, the cams are pressed inwards. This can be done by a rolling, rolling and / or pressing done. The inside deformable cams are in the area of the webs provided openings of the side walls. The described Method for fixing insulating material may also be used Profiles are applied, which no webs or openings exhibit.

Preferably, the cams are pressed into the insulating material or pressed in such a way that this through plastic deformation of the insulating material in a form-fitting manner the insulation material intervene. Of course, it is conceivable that - instead of insulation material - other materials or Elements, such as fire protection elements according to this method be fixed in a profile.

Another aspect of the invention relates to a method for Producing a profile for frames of wall elements, doors or windows, with a top, a bottom and these connecting side walls, wherein the side walls have webs. With the help of a punching or cutting process, in particular one Laser cutting process, be openings in the side walls appropriate. If the profile should have cams, be These preferably in the same step from the side walls punched out or cut. After that, the side walls become welded to the upper part and the lower part.

Advantageously, the upper and lower parts are made of a metal sheet. By a Abkant- and / or Rollformverfahren the Sheets are easily deformed in such a way that preferably on both sides about right-angled bends and arranged thereon, inwardly facing end faces with a Stop arise.

As shown in Figure 1, there is a total designated 1 Profile made up of three main components: a top 16, a lower part 2 and the side elements 5. The components consist of metallic materials, for example Steel, stainless steel or aluminum. FIG. 1 shows an im Cross-section rectangular profile. The respective components are designed as a flat profile. Of course, the shape and geometry in the cross section of a profile 1 designed more complicated be. The individual components, that is the top part 16, the lower part 2 and the side walls 5 do not have to necessarily be flat, but for example itself be configured U- or T-shaped. How out Fig. 1 shows, the profile is elongated. The Side walls 5 and the upper part 16 and the lower part 2 are respectively arranged parallel to each other. The illustrated in Figure 1 Side walls 5 serve as spacers for spacing the parallel upper part 16 and lower part 2. The of Upper part 16, the lower part 2 and formed by the side walls Chamber 13 can accommodate the insulation or fire protection material serve.

The side walls 5 are each by welding to the upper part 16 or connected to the lower part 2. The weld 15 runs while in the longitudinal direction. Instead of a continuous seam interrupted seams (stitching) are conceivable.

Figure 2 shows a profile in which the upper part 16 with the Side wall 3 and the lower part 2 with the side wall 4 in one piece are connected and each having an L-shape in cross section. These two L-profiles are put together and with each other welded, creating a rectangle profile. The figure 2b shows a plan view of a planar profile consisting of the Lower part 2 and the side wall 4, which is for use is provided in the profile 1 according to Figure 2a. This will be this Profile with respect to the edge line 14 to an L-profile according to Figure 2a deformed, rolled or folded.

The weld seam 15 is arranged in the region of the corners of the profile 1. For profiles 1, which have higher static loads For example, a V or I seam would be provided. For this example, the upper part 16 or the lower part would have 2 have an additional bend, which the upper part 16 and the lower part 2 in the area provided Seam would be flush.

FIG. 2b further shows the obliquely extending webs 5, which applied by the application of openings 11 in the side wall 4 become. The webs 5 are based on the longitudinal axis of the profile inclined at an angle of 45 °. Of course are other inclination angles conceivable, for example, inclination angle between preferably 30 ° to 90 °. Of course the webs 5 could also be arranged perpendicular to the longitudinal axis be. The webs 5 and the openings 11 are generally centered arranged in a side wall 4. The web distance a can thereby depending on the required thermal insulation or static requirement for a profile of frames for doors, windows or wall elements vary. The length of the webs 5 depends on the web distance a and from the angle of inclination of the webs. Such a diagonally trained Bridge 5 reduced by its length in relation to the bridge distance a the heat transfer as a result of heat conduction. Should the heat conduction For example, be small, so in particular the Web distance a (in relation to the distance between upper part 16 and Lower part 2) is selected, however, the profile 1 high static and to withstand any dynamic loads a smaller bridge distance chosen. The openings 11 are as figure 2b shows, in the form of a trapezoid. The openings 11 are for example, cut out by a laser cutting process.

Figure 3 shows an approximately U-shaped profile consisting of the two Side walls 3 and 4 as well as from the lower part 2. The upper part 16 is welded to the U-profile with the side walls 3 and 4. The weld 15 is formed as a fillet weld.

Figure 4 shows an alternative to Figure 3 profile. It is in the In contrast to Figure 3, the upper part 16 angled, whereby the Upper part is also 16 U-shaped. This can do that Upper part 16 with the side walls 3 and 4 via a roller seam or a series weld.

FIG. 5 shows a further profile 1. The upper part 16 and the lower part 2 protrude with respect to the side walls 3 and 4 in each case, with which the welded seam 15 are in each case fillet welds. The side walls 3 and 4 serve as spacers (evidently, the height h is equal to the distance A between the upper part 16 and lower part 2) for the upper part 16 and the lower part 2. They each have two parallel guide grooves 10, between which a side member 9 is arranged is. The guide grooves 10 serve in particular also for clamping the side elements 9 to the side walls 3 and / or 4. Such a side member 9 may for example consist of a fire protection element, such as a fire protection strip, a plastic cover strip for covering the webs 5 and the openings 11 or a Center seal exists. Depending on the individual purpose, for example, different thickness tops 16 or bottoms 2 can be used, which, among other things, opens up a variety of applications for the profile 1.
Further exemplary embodiments of the profiles according to the invention are shown in FIGS. 6 and 7. These figures show side walls 3 and 4, the height h is smaller than the distance A between the upper part 16 and lower part 2.

The upper part 16 and the lower part 2 each have parallel to the side wall 3 and 4 extending bends 6, on which the side wall 3 and 4 abut surface. Preferably, the side walls 3 and 4 on the inside, as shown in Figures 6 and 7, attached. By the concern, a contact surface 7, whereby the side walls 3, 4 can be welded to the upper part 16 and lower part 2 in a simple manner. The welding can be done for example by a laser welding process. Of course, an external attachment of the side walls 3 and 4 is also conceivable. By attaching the side walls 3 and 4 on the inside, however, it is possible, for example, to attach side elements 9 to the side walls 3 or 5 between upper part 16 and lower part 2 in such a way that they are approximately flush with respect to the upper parts or lower parts 16 and 2 , Of course, the thickness may vary depending on the intended use of a side member 9. Possible side elements are, for example, fire protection strips, seals or fittings for windows or doors. On a side wall can further, as shown in Figure 6, a further panel 12 are attached. The attachment takes place for example by gluing. The lower part 2 also has a lateral part 17, for example in the form of a flap, in particular a crimp, which arises, for example, by bending and / or folding a sheet. This lateral part 17 can be used for the assembly of a frame for doors or windows as a stop element with respect to adjacent profiles, eg a sash, (not shown in the drawing).
As can be seen from FIG. 7, the side walls 3 and 4 have holders 8. These are U-shaped and serve, in particular, for receiving the side element 9. For example, starting from a metal sheet, it is shaped by means of a bending process in such a way that the two Pages of the sheet a U-shaped bracket 8 is formed. Preferably, the side member 9 is arranged on the sheet before bending, whereby after bending the sheet is positively secured in the U-shaped brackets 8. The resulting side wall 3 and 4 is then welded in the region of the bend 6 of the upper part 16 and the lower part 2. The side element 9 according to FIG. 7 is provided centrally with a T-shaped cam 18. The cam 18 is used in particular for the positive reception of fittings or center seals.

Figures 8a and 8b show variants of arrangements of webs 5, 5 '. For example, FIG. 8a shows that the webs 5 or 5 'are arranged in several rows V-shaped. Thereby the webs 5 and 5 'intersect, thus creating an X-like Course of the bridges. Evidently, the openings 11 'and 11 '' designed as triangles and rhombuses. In Figure 8b will continue a hexagonal opening 11 '' 'shown.

FIG. 9 shows a profile 1 in which the side walls 3 and 4 are arranged offset inwards. The depression thus formed is particularly suitable for receiving side panels such as For example, cover strips, fire protection strips or center seals. These go from the bends 6 of the upper and lower parts 16 or 2 in each case inwardly directed end faces, for example in the form of offsets. An end face 22 has as Completing a stop 23, which parallel to the angulation 6 and thus also parallel to the side walls 3 or 4 runs. The stops 23 of the end faces 22 form bearing surfaces for the side walls 3 and 4. As can be seen from Figure 9, are the oblique end faces 22 angled such that the angle α between end face 22 and bend 6 is about 60 °. Prefers for angle α becomes a range of 20-80 °. Depending on the application are also other embodiments of the front side 22nd imaginable. However, the angle α is greater than 5 ° and smaller as about 170 °. In Figure 10, the end faces 22 are perpendicular (α = 90 °) from the bends. The stopper 23 is relatively short designed. The side walls 3 and 4 are in Area of the end face 22 with the upper part 16 and lower part. 2 welded. In the present embodiment, the side walls 3 and 4 with the help of a fillet 15 directly with the oblique end-side sections 22 welded. Instead of as in Figure 9, in which on both sides inwardly directed end faces 22 are arranged, the profile 1 can only on one side Have end faces 22 and recesses. The other opposite Side could, for example, as in Figures 6 and 7 may be configured.

FIG. 11 shows a variant of a profile 1 with end faces 22. The side wall 3 is bent or deep drawn, resulting in forms a further depression. As shown in Figure 11 (as well from Figures 9 or 10), the side walls are arranged outside. Of course it is also conceivable inside arrangement of the side walls. The side walls could for example, by roll seams or series welds 15 be connected to the sections 23 by welding. imaginable would be at most also (not shown in a figure), that the side walls 3 and 4 would be designed such that the side walls by butt joint each with the ends of the parallel portions 23 of the bend 21 are welded.

A profile 1 in fire protection design is shown in FIG. By the end faces 22 areas are defined, in which In a simple way fire protection elements 24 inserted are. Of course, could also the chamber 13 of the profile. 1 completely filled with fire protection materials. The Fire protection elements 24 or fire protection materials, for example from energy-consuming materials such as alum, glass wool or plaster. The mentioned fire protection elements could for Profiles 1, which are intended exclusively for thermal insulation, be replaced by appropriate heat insulating materials. In the recesses formed by the end faces 22 are Side elements 9 arranged. The side elements 9 could as Fire protection strip made of heat-inflating material be designed. A side member 9 is flat against the Sidewalls 3 or 4 and is preferably secured by gluing. Other types of fastening, for example with the help of Screws are conceivable. Due to the special design of the Abriebungen 21 is also conceivable (especially in a preferred angle α between 20 ° and 90 °) that side elements 9 are connected by clamping or latching with the profile 1.

Figures 13 and 14 show a profile 1, in which the inward directed end faces 22 and the stopper 23 form a groove 25, which picks up the side wall. Through the groove 25 can also a space can be created in which in a simple way Side elements, for example cover elements for the side walls or fire protection strips can be arranged. Provided be used for the upper and lower part metal sheets, can the approximately U-shaped grooves 25 of the side walls 3 and 4 on simple way by a Abkant- or Rollformverfahren getting produced. To produce the profile 1, the preformed Upper and lower parts 16 and 2 in a predefined Position spaced apart. The side walls 3 and 4 are inserted laterally through the upper and lower grooves 25 and then welded. It can also be seen in FIGS. 13 and 14 a web 5 of the side wall 3 has an inwardly directed bead 26 has.

In FIG. 13, the bends 6 are from the top and bottom 16 or 2 about the same height, the side wall 3 approximately in the middle in With respect to the profile 1 is arranged. In Figure 14, the side wall 3 arranged on one side. Compared to the profile according to FIG. 13 extends the side wall 3 in profile 1 according to FIG and the bend 6 'of the lower profile accordingly shortened. This lengthens the webs and the profile. 1 has a higher thermal insulation performance. Of course could also shortened the upper part 16 or both parts accordingly become.

FIG. 15 shows a profile 1 in which, in the middle in the region of Side walls 3 and 4 a rectangular in cross-section insulation element 28 is fitted. The insulating material 28 is preferably fixed by cams (see below the figures 16 and 17). Due to the central arrangement of the insulation material 28, upper and lower chambers 30 and 31 are formed. It is quite conceivable that in the cavities of the Chambers 30 and / or 31 insulation or fire protection material arranged can be. Cables could also pass through these chambers become.

FIG. 16 shows a side view of a side wall (3 or 4), the inclined webs 5 are arranged in a V-shape, whereby approximately triangular openings 11 are formed. The bridges 5 also have a bead in the longitudinal direction of the Stegs runs. The beads 26 are preferably formed by a stamping, Roll or other method produced. Approximately centered on an opening 11 is at the base 29, a cam 27th arranged. The cam 27 is integral with the side wall connected and is preferably by a punching or Laser cutting process produced. With that too can relatively complicated cam shapes are produced. Evidently, the cam 27 toward the base 29 towards a the cam 27 towards the base 29 toward a taper 34, whereby the cam 27 easier and with less effort inwardly deformable. Of course, there are others too Shapes conceivable, for example, the cam 27 rectangular, be triangular or trapezoidal. FIG. 17 shows a Cam 27 in pressed or deformed state. Evidently engages the cam 27 in the insulation material here 28 (with an arrow the direction of depression is indicated). This ensures that the insulation material in particular in the axial or in the longitudinal direction of the profile 1 a has a firm seat.
