Description

Profile and method for producing a profile

The invention relates to a profile for frames of wall elements, doors or windows and a method for producing the profile with the features of the preamble of the independent claims.

Such profiles should in particular also serve to ensure thermal insulation for the frame construction. Another application is in fire protection.

EP 0 802 300 A2, for example, shows a composite profile with two metal profiles and these connecting metal strips, whereby three inner chambers are formed. The metal strips have punched holes, which form webs, to reduce the heat flow of the composite profile. EP 0 802 300 A2 further shows that the metal strips are positively connected to metal profiles having guide grooves. Such a composite profile is relatively difficult to manufacture and expensive by the relatively complicated construction and in particular by the nature of the connection of the central part with the two metal profiles.

DE 195 26 795 describes a composite profile of two spaced metal profiles and an insulating material located between them, wherein the two profiles are each connected to the outside, approximately U-shaped profiles by welding metal webs to the respective side surfaces of the profiles are interconnected. A metal web can also be formed as a plurality of openings having side wall. However, the metal webs or side walls must have an excess length, that is, the height of the metal webs must be greater than the distance between the two profiles. This sidewall can only be laterally attached to the profiles can only be attached laterally to the profiles, so that at least a part of the side wall protrudes. The handling and use of such a profile can be difficult. The outer lying of the side walls also has a disadvantage for a cladding of the side walls. Such a composite profile is also from an optical point of view - the application in the context of wall elements, doors or windows little suitable.

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

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

The profile essentially consists of three components: upper part, lower part and these connecting side walls. Top and bottom each contain an end wall. These components consist of metallic materials, preferably of steel, which have relatively high heat conduction. In order to reduce the heat conduction through the profile, from the upper part to the lower part, the side walls are provided with oblique webs. Due to the oblique arrangement of the webs, the webs are formed based on the distance from the upper part and lower part long. As a result, the heat transfer is reduced by the side walls due to heat conduction through the webs, or improves the thermal insulation of the frame. The greater the inclination or the longer the webs are formed, the higher will be the thermal insulation in principle. The side walls are welded to the upper part and / or to the lower part. The height of the side walls is less than or equal to the distance between the end walls of the upper part and lower part. Thus, a profile with good thermal insulation and good static properties is easy and inexpensive to produce. Such a profile is also characterized by the fact that it can be used for fire protection or burglary protection.

Particularly advantageously, the upper part and / or the lower part has at least one angled section running parallel to a side wall to form a contact surface with a side wall. In the area of the contact surface, the upper part or the lower part is then welded to the side walls. Such an arrangement substantially simplifies welding. Since the bend rests parallel to a side wall and flat against a side wall, the side walls can be easily connected to the upper part or lower part by means of laser welding methods. The manufacturing cost of a profile can be significantly reduced. This embodiment is particularly well suited for a rational, automatic series 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. On the inside, in this context, means that the side walls are arranged on the side facing the chamber. This has the particular advantage that the profile with respect to the side wall has no protruding parts. Since at least a part of the side wall is "hidden", one meets such profile higher aesthetic requirements. In addition, a side member, such as a plastic strip or fire protection strip easier to attach to the side wall, because the side wall is arranged inside the profile, for example, side elements can be mounted flush with the bends on the side walls.

It is advantageous if the side walls have parallel guide grooves. A guide groove can serve as a stop for a second or adjacent profile. However, two mutually parallel guide grooves can also be used for receiving side elements, such as a plastic strip or fire bars.

The invention can be implemented particularly easily if at least one side wall has in each case laterally arranged, preferably U-shaped holders for receiving a side element. Such a holder can be made in a simple manner by a two-sided Abwinkein the side wall such that in each case in the upper part and the lower part of the profile side facing a U-shaped bracket is formed. A recording of a page element is thus easy and cheap to produce. A web can have a running in the longitudinal direction of the web bead. In general, the bead is designed in the form of an inwardly directed indentation. It is advantageous that the profile withstands higher static requirements.

The webs may advantageously be formed as one or more rows of approximately V-shaped arrangements. A series of approximately V-shaped arrangements of webs is achieved, for example, by providing openings in the side walls in the form of mutually offset triangles or trapezoids. be brought. Several rows of approximately V-shaped arrays of ridges form a cross-shaped or X-shaped arrangement. However, the webs do not necessarily have to be created only by attaching openings in the side walls. So it is quite possible to weld the bars individually with the upper part and with the lower part. The basically about V-shaped arrangement of the webs has the advantage that the profile has good thermal insulation and good static properties. An additional advantage is that a significant weight saving is possible.

On the side walls panels may be appropriate. Such a cladding has the advantage that the side wall can be covered easily and inexpensively. Coverings can also have different colors.

If the upper part and the lower part have bends, it is advantageous if inwardly directed end faces are arranged on the bends at their end region. The side walls of the profile are welded in the region of the end faces with the upper part and the lower part. The end faces are preferably provided with a stop for a side wall, which defines the end of an upper or lower 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 a depression is created by the inwardly directed end faces on the profile, in which elements such as fire protection or cover strips can be attached in an advantageous manner. The profile thus generally has no laterally projecting parts. The respectively opposite, preferably parallel to the bends extending stops of the end faces of an upper part and a lower part form bearing surfaces for each a Sei- tenwand. Next could be in a simple way and. Way in the chamber of the profile each upper part and / or in the lower part in the area defined by the end faces of thermal insulation panels, or in particular also fire protection plates are added.

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

Particularly advantageous form an inwardly directed end face and a stopper a groove for receiving side elements. With upper and lower parts made of sheet metal, for example, the groove can be produced particularly easily by Abkantprozesse. The groove forms an approximately U-shaped holder for the side elements, wherein the width and depth of the groove depend on the particular intended use of the profile. If sheets of metal are used for the upper and lower part, they can be produced in a simple manner by a bending or roll forming process.

Particularly advantageously, the side walls are welded to the end faces of the bends. A weld can be done relatively easily from the outside.

Alternatively, the side walls can be encrypted with the preferably short parallel stops of the end faces. 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. Particularly advantageously, the welds are designed as stitching.

It is advantageous if the upper part and lower part made of steel and the side walls made of stainless steel. Due to the different types of steel, the profile has particularly good thermal insulation properties, as stainless steel conducts heat less well than ordinary steel. The profile can still be produced relatively inexpensively.

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

Another aspect of the invention relates to a profile for frames of wall elements, doors or windows having a top and a bottom and connecting side walls having openings. On the side walls deformable cams for fixing insulating material are provided in the region of the openings inwardly. Depending on the intended use, one or a plurality of cams may be provided per opening. The shape of the cams is arbitrary, but they should be relatively easy to deform inwardly. With the help of the cam, a profile, in the chamber insulation material is arranged, characterized by an advantageous fixation of the insulation material. In particular, with respect to the longitudinal direction of the profile, the insulating material sits firmly in the chamber and slipping is impossible. By the cams and insulation material, which only partially fills the chamber of the profile and in particular is arranged centrally in the region of the side walls, are fixed in a simple manner. Advantageously, the insulation material by the cam force and / or positively held in the chamber of the profile. For example, the insulating material can ring by plastic deformation of the insulating material in this. But it is also conceivable that the insulation material has preformed corresponding Ausspaarungen for receiving the inwardly deformable cams. It is also conceivable that the cams additionally have inwardly directed claw-like elevations.

Preferably, a cam is arranged approximately centrally in the region of the base of an opening. Base forms thereby de that part of the opening, which runs in the longitudinal direction of the profile. An advantage of this arrangement of cams is that the cams are located in a statically favorable location and the cams can be pressed rationally and easily.

Insulation material can be arranged in the region of the side walls, whereby an upper and lower chamber is formed. The insulating element is preferably approximately rectangular in cross section. These two chambers can also be filled depending on the application with insulation material, fire protection elements or the like. 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 an upper part, a lower part and connecting side walls, wherein the side walls have webs for improving the thermal insulation properties of the profile and cams for fixing insulating material. For fixing the isola- tion material, which is arranged in the chamber of the profile, the cams are pressed inwards. This can be done by rolling, rolling and / or pressing. The inwardly deformable cams are provided in the region of the openings formed by the webs of the side walls. The described method for fixing insulation material can also be applied to profiles which have no webs or openings.

Preferably, the cams are pressed into the insulating material or pushed inwards in such a way that they engage in a form-fitting manner into the insulating material by plastic deformation of the insulating material. Of course, it is conceivable that - instead of insulating material - other materials or elements, such as fire protection elements are fixed in a profile by this method.

A further aspect of the invention relates to a method for producing a profile for frames of wall elements, doors or windows, comprising an upper part, a lower part and connecting side walls, the side walls having webs. By means of a punching or cutting process, in particular a laser cutting process, openings are made in the side walls. If the profile should have cams, they are preferably punched or cut out of the side walls in the same step. Thereafter, the side walls are 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 can be deformed in a simple manner such that preferably on both sides about right-angled bends and arranged thereon, facing inward ends with a stop arise.

As shown in FIG. 1, a profile designated as a whole by 1 consists essentially of three components: an upper part 16, a lower part 2 and the side elements 5. The components consist of metallic materials, for example wise steel, stainless steel or aluminum. Figure 1 shows a rectangular cross-sectional profile. The respective components are designed as flat profiles. Of course, the shape and geometry in the cross section of a profile 1 can be made more complicated. The individual components, that is, the upper part 16, the lower part 2 and the side walls 5 need not necessarily be formed flat, but may for example be configured even U- or T-shaped. As is apparent from Fig. 1, the profile is elongated. The side walls 5 and the upper part 16 and the lower part 2 are each arranged parallel to each other. The side walls 5 shown in Figure 1 serve as spacers for spacing the parallel extending upper part 16 and lower part 2. The upper part 16, the lower part 2 and the side walls formed chamber 13 may serve to accommodate insulation or fire protection material.

The side walls 5 are each connected by welding to the upper part 16 and to the lower part 2. The weld seam 15 extends 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 are integrally connected and each having an L-shape in cross section. These two L-profiles are joined together and welded together, creating a rectangular profile. FIG. 2b shows a plan view of a planar profile consisting of the lower part 2 and the side wall 4, which is intended for use in the profile 1 according to FIG. 2a. In this case, this profile is deformed with respect to the edge line 14 to an L-profile according to Figure 2a, rolled or folded. The weld seam 15 is arranged in the region of the corners of the profile 1. For profiles 1, which are exposed to higher static loads, for example, a V or I seam would be provided. For this purpose, for example, the upper part 16 or the lower part 2 would have an additional bend, whereby the upper part 16 and the lower part 2 would be flush in the region of the intended seam.

FIG. 2 b further shows the obliquely extending webs 5, which are applied by the application of openings 11 in the side wall 4. The webs 5 are inclined relative to the longitudinal axis of the profile at an angle of 45 °. Of course, other inclination angles are conceivable, for example, inclination angle between preferably 30 ° to 90 °. Of course, the webs 5 could also be arranged perpendicular to the longitudinal axis. The webs 5 and the openings 11 are usually arranged centrally in a side wall 4. The web distance a can vary depending on the required thermal insulation or static requirement for a profile of frames for doors, windows or wall panels. The length of the webs 5 depends on the web distance a and on the inclination angle of the webs. Such an obliquely formed web 5 reduced by its length in relation to the web distance a the heat transfer due to heat conduction. If the heat conduction, for example, be small, so in particular the web distance a (in relation to the distance between the upper part 16 and lower part 2) is selected, however, if the profile 1 hold high static and eventual dynamic loads withstand, so a smaller land distance is selected. The openings 11 are as Figure 2b shows, in the form of a trapezoid. The openings 11 are cut out, for example, by a laser cutting method. Figure 3 shows an approximately U-shaped profile consisting of the two side walls 3 and 4 and 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. In this case, in contrast to Figure 3, the upper part 16 angled, whereby the upper part is also 16 U-shaped. Thereby, the upper part 16 can be connected to the side walls 3 and 4 via a roll seam or a row 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. The contact forms a contact surface 7, as a result of which the side walls 3, 4 can be welded to the upper part 16 or lower part 2 in a simple manner. The welding can be done for example by a laser welding process. Of course, an outer side 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, this is done with the aid of a plate Forming bending that forms a U-shaped bracket 8 on both sides of the sheet. 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 ^Λ . For example, Figure 8a shows that the webs 5 and 5 are arranged in several rows V-shaped. As a result, the webs 5 and 5 intersect, thereby creating an X-like course of the webs. Evidently, the openings 11 'and 11 ^{λ are designed} as triangles and rhombuses. FIG. 8b further shows a hexagonal opening II ^, FIG.

FIG. 9 shows a profile 1 in which the side walls 3 and 4 are arranged offset inwards. The recess thus formed is particularly well suited for receiving side parts such as cover strips, fire protection strips or center seals. These go from the bends 6 of the upper and lower parts 16 and 2 respectively inwardly directed end faces, such as in the form of offsets. An end face 22 has as a conclusion to a stop 23, which runs parallel to the bend 6 and thus parallel to the side walls 3 or 4. The stops 23 of the end faces 22 form bearing surfaces for the side walls 3 and 4. As shown in Figure 9, the oblique end faces 22 are angled such that the angle α between the end face 22 and 6 angulation is about 60 °. Preferred for angle α is a range of 20-80 °. Depending on the In other applications of the end face 22 are conceivable application. However, the angle α is greater than 5 ° and less than about 170 °. In Figure 10, the end faces 22 are at right angles (= 90 °) from the bends. The stopper 23 is designed to be relatively short. The side walls 3 and 4 are welded in the region of the end face 22 with the upper part 16 and lower part 2. In the present exemplary embodiment, the side walls 3 and 4 are welded directly to the oblique front side sections 22 with the aid of a fillet weld 15. Instead of as shown in Figure 9, in which both sides inwardly directed end faces 22 are arranged, the profile 1 may have only on one side end faces 22 and depressions. The other opposite side could for example be designed as shown in Figures 6 and 7.

Figure 11 shows a variant of a profile 1 with end faces 22. The side wall 3 is bent or deep-drawn, thereby forming a further depression. As can be seen from FIG. 11 (as well as from FIGS. 9 or 10), the side walls are arranged on the outside. It is also conceivable, of course, an internal arrangement of the side walls. The side walls could, for example, be connected to the sections 23 by welding by means of roll seams or row welding seams 15. At best, it would also be conceivable (not shown in a figure) that the side walls 3 and 4 would be configured such that the side walls are welded by butt joint respectively with the ends of the parallel portions 23 of the bend 21.

A profile 1 in fire protection design is shown in FIG. By the end faces 22 areas are defined, in which in a simple manner fire protection elements 24 can be inserted. Of course, the chamber 13 of the profile 1 could be completely filled with fire protection materials. The Fire protection elements 24 or fire protection materials consist for example of energy-consuming materials such as alum, glass wool or gypsum. The above-mentioned fire protection elements could be replaced by corresponding heat-insulating materials for profiles 1, which are provided exclusively for thermal insulation. In the recesses formed by the end faces 22 side elements 9 are arranged. The side elements 9 could be designed as a fire protection strip of heat-inflating material. A side member 9 is flat on the side walls 3 or 4 and is preferably secured by gluing. Other types of fastening, for example by means of screws, are conceivable. Due to the particular embodiment of the Abköpfungen 21 is also conceivable (especially at a preferred angle 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 inwardly directed end faces 22 and the stop 23 form a groove 25 which receives the side wall. Through the groove 25, a space can be created in which in a simple way side elements, such as cover elements for the side walls or fire protection strips can be arranged. If sheets of metal are used for the upper and lower part, the approximately U-shaped grooves 25 of the side walls 3 and 4 can be produced in a simple manner by a Abkant- or roll forming process. To produce the profile 1, the preformed upper and lower parts 16 and 2 are spaced from each other in a predefined position. The side walls 3 and 4 are laterally inserted through the upper and lower grooves 25 and then welded. Furthermore, it can be seen in FIGS. 13 and 14 that a web 5 of the side wall 3 has an inwardly directed bead 26. In Figure 13, the bends 6 of the top and bottom 16 and 2 are about the same height, the side wall 3 is arranged approximately centrally with respect to the profile 1. In Figure 14, the side wall 3 is arranged on one side. In comparison to the profile according to FIG. 13, the side wall 3 is lengthened in profile 1 according to FIG. 14 and the angled portion 6 'of the lower profile is correspondingly shortened. This lengthens the bars and the profile 1 has a higher thermal insulation performance. Of course, the upper part 16 or both parts could be shortened accordingly.

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

Figure 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 webs 5 also have a bead extending in the longitudinal direction of the web. The beads 26 are preferably made by a stamping, rolling or other method. Approximately centrally with respect to an opening 11, a cam 27 is arranged on the base 29. The cam 27 is integrally connected to the side wall and is preferably made by a punching or laser cutting process. This also relatively complicated cam shapes can be produced. Evidently the cam 27 towards the base 29 towards a taper 34, whereby the cam 27 is deformed easier and with less effort inwardly. Of course, other shapes are conceivable, for example, the cam 27 may be rectangular, triangular or trapezoidal. FIG. 17 shows a cam 27 in a pressed-in or deformed state. Evidently engages here the cam 27 in the insulating material 28 (with an arrow is the impression direction indicated). This ensures that the insulation material, in particular in the axial or in the longitudinal direction of the profile 1 has a tight fit.
