Definitions
- the invention relates to an extruded window or door hollow chamber profile according to the preamble of claim 1.
- a hollow chamber profile can preferably have an integrated stiffener ex works and includes at least one fastening area for fastening the hollow chamber profile to or for connecting the hollow chamber profile to an external component , which fastening area is designed and provided for receiving a fastening means profiled on the edge.
- the hollow chamber profile has an intermediate region which is designed as a reinforcement chamber to accommodate a preferably metallic reinforcement.
- the hollow chamber profile has at least one fastening channel in the fastening area, which is oriented perpendicular to an extrusion longitudinal direction of the hollow chamber profile.
- the fastening channel has a channel longitudinal axis, is closed at its ends perpendicular to the channel longitudinal axis by an outer wall of the hollow chamber profile and is laterally delimited parallel to the channel longitudinal axis by channel side walls.
- the invention also relates to claim 13, a system consisting of an extruded window or door hollow chamber profile according to the invention and at least one fastening means profiled on the edge, preferably a screw.
- the invention further relates to a frame for a door or a window, which is formed from several sections of hollow chamber profiles according to the invention which are connected to one another in connection areas, preferably welded.
- a generic hollow chamber profile is, for example, from DE 10 2014 104 190 A1 , the DE 10 2020 108 412.9 , the EP 2 079 895 B1 or the DE 43 38 181 C1 known. From this prior art there is a hollow chamber profile known with a continuous fastening channel, which fastening channel can be interrupted by intermediate webs.
- Window profiles known on the market or generally hollow chamber profiles of the type mentioned must be stiffened accordingly depending on the existing requirements and the expected loads.
- Conventional window profiles have specially sized hollow chambers.
- Metal profiles are inserted into these chambers and screwed together to increase the stability of the window or door.
- Such chambers are called reinforcement chambers.
- fiber-reinforced materials or thermally separated metal reinforcements are increasingly being used, which can already be integrated into the profile at the factory.
- the windows are usually attached to the masonry at defined distances using mounting or fastening devices, such as standoff mounting screws (reveal) of the building or connected to any other external components.
- mounting or fastening devices such as standoff mounting screws (reveal) of the building or connected to any other external components.
- the screw connection penetrates the reinforcement chamber so that the profile is attached to the masonry via the reinforcement.
- the required screw retention in the profile is achieved, for example, with the help of screw channels.
- a frame is the part of a window or door frame that is firmly connected to the masonry.
- the movable part of the window or door is called the sash or sash frame.
- adjacent hollow chambers of the profile can then be stiffened.
- the drilling and screwing positions must be offset in order to connect the bracing to the masonry. This is difficult to implement in terms of control and production technology.
- the invention is therefore based on the object of developing a hollow chamber profile of the type mentioned in such a way that a fiber-reinforced profile can be realized into which a metal stiffener can be inserted if necessary.
- the drilling axes for assembly should be placed or able to be placed in such a way that the same drilling and drilling axes can be achieved without and with metal reinforcement Screw axle can be used for assembly.
- suitable bracing can then be used.
- an extruded window or door hollow chamber profile preferably with reinforcement integrated ex works, with at least one fastening area for fastening the hollow chamber profile to or for connecting the hollow chamber profile to an external component, in particular to a masonry (structure), which fastening area is for receiving a fastening means profiled on the edge is designed and provided, which hollow chamber profile has an intermediate region which is designed as a reinforcement chamber for receiving a preferably metallic reinforcement, which hollow chamber profile has at least one fastening channel in the fastening area, which is oriented perpendicular to an extrusion longitudinal direction of the hollow chamber profile, which fastening channel has a Channel longitudinal axis, is closed at its ends perpendicular to the channel longitudinal axis by an outer wall of the hollow chamber profile and is laterally limited parallel to the channel longitudinal axis by channel side walls, the fastening channel between the two outer walls in at least two partial fastening channels (or screw chambers) is divided, which partial fastening channels are spaced apart from one another in the direction of
- the fastening means is inserted into the fastening channel along the longitudinal axis of the channel and is introduced into the partial fastening channels, the external component being arranged or to be arranged in an extension of the channel's longitudinal axis; and/or that the fastening means is introduced transversely to the channel longitudinal axis in at least one of the partial fastening channels, the external component being arranged or to be arranged laterally spaced apart from the channel longitudinal axis in the region of an end face of the hollow chamber profile that is different from the two outer walls; wherein preferably an outer diameter of the fastening means is larger than a clear cross section of the partial fastening channels or of at least one of the partial fastening channels.
- a frame according to the invention for a door or a window which is formed from several sections of hollow chamber profiles according to the invention which are connected to one another in connection areas, preferably welded, it is provided that in at least one of the connection areas a preferably metallic connecting element, preferably a connection angle, is connected in two to one another connected hollow chamber profile sections are introduced in the area of the respective fastening channel; and/or that a preferably metallic reinforcing element is inserted into the at least one intermediate region or into at least one of the intermediate regions.
- the proposed construction is designed in such a way that the screw hold in the profile is sufficiently dimensioned for standard loads even without additional reinforcement due to the partial fastening channels or screw chambers provided according to the invention.
- a comparable level of rigidity to solutions with a continuous screw channel could be determined, particularly for mounting devices loaded with shear forces (fastening screws). Transverse forces result from loads that typically occur on windows due to wind loads.
- a (metallic) reinforcement can also be inserted into the profile in the intermediate area mentioned.
- the mounting holes advantageously remain on the same axis and position.
- the screw connection then penetrates the material accumulations in the profile, which are preferably present in the area of the partial fastening channels or screw chambers (or are formed by the screw chambers themselves), and the stiffening equally.
- the profile can be specifically and partially stiffened without having to change the production process for the holes and screw connections. The reinforcement effect can therefore be dimensioned particularly efficiently.
- screw chamber preferably means that the chambers in question (in a cross section through the profile) are surrounded or enclosed all around by profile material (webs).
- profile material webs.
- the screw chambers themselves represent accumulations of material in the profile, which increases stability.
- a special development of the hollow chamber profile according to the invention provides that the channel side walls are at a greater distance from one another in the intermediate region than in an area of the partial fastening channels. In this way, sufficient space can be created in the intermediate area for the introduction of a suitably sized reinforcement profile.
- the channel side walls recede in the intermediate region at least to such an extent that there is no longer any interaction with the mounting/fastening means.
- the hollow chamber profile according to the invention provides that an accumulation of material or a thickening, in particular of the relevant outer wall, is provided within the partial fastening channels, preferably on at least one of the two outer walls.
- the holding effect already mentioned can be improved even further.
- the partial fastening channels themselves also represent certain accumulations of material, as has already been pointed out. This effect can be further improved by the additional material accumulations or thickenings mentioned
- the channel side walls have projections on their inside which delimits at least one of the partial fastening channels.
- Such projections can interact mechanically with a fastener introduced into the channel in order to improve the fastening effect.
- a maximum clear distance is provided between projections that extend from different channel side walls in a transverse direction transverse to the channel longitudinal axis, which maximum clear distance is preferably 2 mm does not exceed; and/or that a maximum distance is provided between two projections adjacent in a longitudinal direction along the channel longitudinal axis, which maximum distance is preferably 2 mm or less; and/or that a maximum distance of preferably 2 mm or less is provided between a projection and a channel side wall opposite the projection.
- the specified values have proven to be particularly suitable.
- projections emanating from different channel side walls are offset in the longitudinal direction along the channel longitudinal axis or are arranged at the same height. This allows the fastening effect to be adapted to different requirements.
- the projections extend at an angle with respect to the relevant channel side walls, which angle is preferably either 90° or deviates from 90° and is preferably between 30° and 60° , most preferably 45°, with projections arranged at the same height preferably having the same angles. This can also contribute to an improved fastening effect.
- the intermediate region is designed as a reinforcement chamber for receiving a preferably metallic reinforcement.
- the design has already been explained in detail above.
- This can in particular mean that the intermediate region is designed to be sufficiently large in order to be able to accommodate a statically effective reinforcement. This can imply that in the direction of the channel longitudinal axis there is a significant distance between the partial fastening channels or screw chambers or that the channel side walls in the intermediate region stand back significantly compared to the partial fastening channels.
- the reinforcement chamber can have typical dimensions between 20 and 50 mm in height and width.
- the screw chambers can have a width of preferably 6 to 8 mm (chamber width) and a height of 3 to 10 mm.
- the channel side walls are laterally supported in the area of at least one partial fastening channel at least on one side, preferably on both sides, transversely to the longitudinal direction of extrusion. This improves the stability of the partial fastening channels when a fastener is inserted and thus increases the holding effect.
- At least one channel side wall is supported at an angle of 90 degrees with respect to the longitudinal axis of the channel. In practice, this results in a particularly good stabilization effect.
- At least one channel side wall is supported at an angle other than 90 degrees with respect to the channel longitudinal axis. This can have particular advantages with regard to the use of material required in the production of the hollow chamber profile.
- hollow chamber profile provides that at least one partial fastening channel is designed as an attachment to a continuous transverse web of the hollow chamber profile, preferably in the assembly direction below or outside the relevant crossbar.
- a design has proven to be particularly robust in practice.
- the crossbar in question can create a thermally effective additional insulating chamber within the profile, which brings corresponding energetic advantages.
- the fastening channel is at least partially filled with a solid or pasty material, preferably with a thermally effective insulating material and/or a fastening material, in particular an insulating foam or injection mortar. This allows both the thermal insulation properties and the holding effect to be further improved.
- Figure 1 shows a cross section through a conventional window profile or hollow chamber profile 1 according to the prior art with steel reinforcement 2 and with a mounting means 3 (fastening screw) for attaching the window profile 1 to a building or structure 4.
- FIG. 2 shows a cross section through a hollow chamber profile 1 according to the invention.
- the hollow chamber profile 1 has, at reference number 5, a factory-integrated stiffener, in particular made of a fiber composite material.
- the hollow chamber profile 1 at reference number 6 has a fastening area which is used to fasten the hollow chamber profile 1 to or for connecting the hollow chamber profile 1 to an external component, in the present case with the structure 4, which is below or outside the hollow chamber profile in the assembly direction (screwing direction). 1 is arranged.
- the fastening area 6 is designed and provided to accommodate a fastening means profiled on the edge, namely the fastening screw 3, as can easily be seen from the illustration.
- the hollow chamber profile 1 has a fastening channel 7 in the fastening area 6, which is oriented perpendicular to a longitudinal extrusion direction 8 of the hollow chamber profile 1, which longitudinal extrusion direction 8 extends into the plane of the drawing.
- the fastening channel 7 has a channel longitudinal axis 9, which is in Figure 2 is shown as a dashed line. Furthermore, the fastening channel 7 is closed at its ends perpendicular to the channel longitudinal axis 9 by an outer wall of the hollow chamber profile 1. These outer walls are in Figure 2 provided with the reference numbers 1a or 1b. Parallel to the channel longitudinal axis 9, the fastening channel 7 is laterally delimited by channel side walls 7a, 7b. However, these channel side walls 7a, 7b are not designed to be smooth and continuous, but rather have various special features according to the invention:
- the fastening channel 7 is namely divided between the two outer walls 1a, 1b into two partial fastening channels 7.1 and 7.2, which partial fastening channels 7.1, 7.2 (here also referred to as screw chambers) in the direction of the channel longitudinal axis 9 through at least one intermediate region 10 from each other are spaced apart.
- the intermediate area 10 is sufficient large dimensions so that additional reinforcement can be inserted into it (compare reference numeral 2 in Figure 1 and Figure 3 ).
- the channel side wall 7a initially forms the left boundary of the (upper) partial fastening channel 7.1, then extends parallel to the outer wall 1a further to the left, away from the channel longitudinal axis 9, then bends downwards parallel to the channel longitudinal axis 9 and then merges into the outer wall 1b.
- the channel side wall 7b initially forms the right boundary of the (upper) partial fastening channel 7.1, then extends obliquely upwards towards the outer wall 1a and is then formed by the (right) stiffener 5 or by the outer wall 1b.
- the fastening channel 7 only has defined channel side walls in the area of the partial fastening channels 7.1, 7.2 mentioned.
- the intermediate area 10 mentioned or possibly in other intermediate areas there is therefore no channel side wall in the narrower sense, although of course there are continuous structures within the hollow chamber profile 1 parallel to the channel longitudinal axis 9.
- the fastening means 3 traverses or can traverse the hollow chamber profile 1 without interacting with any structures within the hollow chamber profile 1.
- screw chamber is well expressed by the alternatively or synonymously used term “screw chamber” because it suggests that the partial fastening channels are (closed) closed structures within the hollow chamber profile 1.
- the upper screw chamber or the partial fastening channel 7.1 is arranged between the outer wall 1a and a parallel to the outer wall 1a Crossbar 11 is formed.
- the lower screw chamber or partial fastening channel 7.2 is designed, so to speak, as an approach below the hollow chamber profile 1 (below the (profile) outer wall 1b).
- the outer wall 1a has a thickening or accumulation of material 12 within the hollow chamber profile 1, while projections 13 are provided on the channel side walls within the partial fastening channel 7.2, which extend approximately transversely to the longitudinal axis 9 of the channel.
- a clear distance between the channel side walls 7a, 7b or the projections 13 in the area of the screw chambers is coordinated with the mounting or fastening means 3 in such a way that this engages with its edge profile 3a in the channel side walls or the projections 13.
- the fastening means 3 can also be screwed into the screw chambers 7.1, 7.2 in the longitudinal extrusion direction 8 of the hollow chamber profile 1, for example in order to fasten additional elements, such as fittings or the like, to the hollow chamber profile 1. This also applies to the screw chambers explained below Figures 4 to 7 .
- Figure 3 shows the same hollow chamber profile 1 as in Figure 2 , but with metallic reinforcement 2 introduced into the intermediate area 10 mentioned. In comparison with Figure 2 It follows that the channel longitudinal axis 9 and the insertion direction of the mounting or fastening means 3 have remained unchanged.
- FIG. 4 Further embodiments of a hollow chamber profile 1 according to the invention are now shown in cross section, each without reinforcement, structure or assembly means. Only the essential differences to the hollow chamber profile 1 according to the Figures 2 and 3 discussed in more detail:
- the hollow chamber profile 1 has three partial fastening channels or screw chambers 7.1 to 7.3.
- the upper screw chamber 7.1 and the lower screw chamber 7.3 are identical to the screw chambers 7.1, 7.2 according to Figure 2 educated.
- the hollow chamber profile 1 according to Figure 4 in comparison with the hollow chamber profile Figure 2 in the lower area there are additional hollow chambers 14.1 to 14.3, which form an additional profile level.
- the screw chamber 7.2 is provided, which, similar to the screw chamber 7.3, is designed as an approach below a crossbar 15 and also has projections 13. All screw chambers 7.1 to 7.3 are aligned along the channel longitudinal axis 9 and are separated from one another along the channel longitudinal axis 9 (namely by the intermediate regions 10, 10 ').
- Figure 5 shows a variant of the design according to Figure 4 , in which a further crossbar 15 'is provided in the assembly direction below the crossbar 15, which extends parallel to the crossbar 15 and runs at the level of the lower end (in the assembly direction) of the partial fastening channel (screw chamber) 7.2.
- the intermediate region 10' is correspondingly formed between the lower crossbar 15' and the outer wall 1b of the hollow chamber profile 1, as shown.
- the middle screw chamber 7.2 is not designed as an extension below the transverse web 15, but rather is formed at a right angle to a vertical intermediate web 18 via two short transverse webs 16.1, 16.2, which form a further hollow chamber 17 between them, which intermediate web 18 has a lateral (right ) Limitation of the middle hollow chamber 14.2 forms.
- the screw chamber 7.2 is arranged with an approximately square contour essentially in the middle of the hollow chamber 14.2, with an oblique connecting web 16' extending from each corner of the screw chamber 7.2 into a corresponding corner of the hollow chamber 14.2.
- Figure 8 a section in or parallel to a glazing plane through a frame 20 for a door or a window, in particular a frame, which consists of several sections 1.1-1.4 of hollow chamber profiles 1 according to the invention (cf. Figures 2 to 7 ) is formed.
- the hollow chamber profile sections 1.1-1.4 are connected to one another in pairs in connection areas 21, preferably welded.
- connection areas 21 preferably welded.
- a preferably metallic connecting element 22 in the form of an L-shaped connecting angle with its two legs 23 (designated only for one connecting element 22) in two interconnected hollow chamber profile sections 1.1-1.4 in the area of the respective Intermediate area 10 (dash-dotted line) introduced. It can be held therein in a clamping, force-fitting manner or in some other way (eg materially bonded) in order to reinforce the connection areas 21.
- This embodiment is not limited in terms of the type and number of connecting elements 22.
- the frame 20 can be connected to external components via the hollow chamber profile sections 1.1-1.4 in the manner described, for example with a soffit surrounding or receiving the frame (structure 4, not shown here, cf. Figure 2 ).
- a reinforcement or a reinforcement element is introduced into one of the intermediate areas 10 at reference number 2, as described above with reference to Figure 3 already described in detail.
- the other intermediate areas 10 can also be used in accordance with Figure 8 take up the appropriate reinforcements 2.
- the reinforcements 2 can also extend into the connection areas 21, which in Figure 8 is not shown.

Ein gattungsgemäßes Hohlkammerprofil ist beispielsweise aus der
Marktbekannte Fensterprofile bzw. allgemein Hohlkammerprofile der genannten Art müssen abhängig von den vorliegenden Anforderungen und den zu erwarteten Belastungen entsprechend ausgesteift werden. Konventionelle Fensterprofile weisen speziell dafür dimensionierte Hohlkammern auf. In diese Kammern werden Metallprofile eingeschoben und verschraubt, um die Stabilität des Fensters oder der Tür zu erhöhen. Solche Kammern werden als Armierungskammern bezeichnet. Obwohl vorstehend teilweise nur von Fenstern die Rede war, gilt dieselbe Problematik auch für Türprofile, weswegen nachfolgende auch einfach von "Hohlkammerprofilen" oder kurz von "Profilen" die Rede ist.Window profiles known on the market or generally hollow chamber profiles of the type mentioned must be stiffened accordingly depending on the existing requirements and the expected loads. Conventional window profiles have specially sized hollow chambers. Metal profiles are inserted into these chambers and screwed together to increase the stability of the window or door. Such chambers are called reinforcement chambers. Although we only talked about windows above, the same problem also applies to door profiles, which is why the following is simply referred to as “hollow chamber profiles” or “profiles” for short.
Alternativ kommen vermehrt auch faserverstärkte Materialien oder thermisch getrennte Metallaussteifungen zum Einsatz, die bereits ab Werk im Profil integriert sein können.Alternatively, fiber-reinforced materials or thermally separated metal reinforcements are increasingly being used, which can already be integrated into the profile at the factory.
Metalle haben eine hohe thermische Leitfähigkeit. Die Armierungen führen deshalb zu einer Verschlechterung der Wärmedämmung innerhalb der Konstruktion. Neuartige Konstruktionen mit faserverstärkten Anteilen, oder mit thermisch getrennten Aussteifungen, können die Wärmedämmung zwar erheblich verbessern. Aufgrund der stark variierenden Belastungen je nach Einbauort und Anwendungsfall ist eine passgenaue Dimensionierung der ab Werk im Profil integrierten Aussteifungen aber nur sehr unpräzise. Die Aussteifung ist deshalb je nach Anwendungsfall oftmals über- oder unterdimensioniert. In einigen Anwendungsfällen ist eine zusätzliche Aussteifung aus Metall deshalb vorteilhaft oder sogar erforderlich.Metals have high thermal conductivity. The reinforcements therefore lead to a deterioration in the thermal insulation within the construction. Innovative constructions with fiber-reinforced components or with thermally separated stiffeners can significantly improve thermal insulation. However, due to the greatly varying loads depending on the installation location and application, it is very imprecise to dimension the stiffeners integrated into the profile ex works. The stiffening is therefore often over- or under-dimensioned depending on the application. In some applications, additional metal reinforcement is therefore advantageous or even necessary.
Die Fenster werden üblicherweise mit Montage- oder Befestigungsmitteln, wie z.B. Abstandsmontageschrauben, in definierten Abständen mit dem Mauerwerk (Laibung) des Baukörpers oder mit beliebigen anderen externen Komponenten verbunden. Die Verschraubung durchdringt bei konventionellen Lösungen die Armierungskammer, sodass das Profil über die Armierung an dem Mauerwerk befestigt wird. Bei faserverstärkten Profilen wird der erforderliche Schraubenhalt im Profil beispielsweise mit Hilfe von Schraubkanälen erzielt.The windows are usually attached to the masonry at defined distances using mounting or fastening devices, such as standoff mounting screws (reveal) of the building or connected to any other external components. In conventional solutions, the screw connection penetrates the reinforcement chamber so that the profile is attached to the masonry via the reinforcement. In the case of fiber-reinforced profiles, the required screw retention in the profile is achieved, for example, with the help of screw channels.
Das Vorsehen eines durchgehenden Schraubkanals gemäß dem genannten Stand der Technik hat allerdings den prinzipiellen Nachteil, dass keine zusätzliche Armierung in diesem Bereich mehr eingesetzt werden kann. Dadurch wird der Anwendungsbereich entsprechend ausgestalteter Blendrahmenprofile stark eingegrenzt. Bei einem Blendrahmen handelt es sich um denjenigen Teil eines Fenster- oder Türrahmens, der fest mit dem Mauerwerk verbunden ist. Der bewegliche Teil des Fensters oder der Tür wird dagegen als Flügel oder Flügelrahmen bezeichnet.However, the provision of a continuous screw channel according to the prior art mentioned has the fundamental disadvantage that additional reinforcement can no longer be used in this area. This greatly limits the area of application of appropriately designed frame profiles. A frame is the part of a window or door frame that is firmly connected to the masonry. The movable part of the window or door, on the other hand, is called the sash or sash frame.
In manchen Konstruktionen können dafür dann benachbarte Hohlkammern des Profils ausgesteift werden. Allerdings müssen bei einer solchen Aussteifung von benachbarten Hohlkammern die Bohr- und Schraubpositionen versetzt werden, um die Aussteifung mit dem Mauerwerk zu verbinden. Das ist steuerungs- und fertigungstechnisch nur erschwert umsetzbar.In some constructions, adjacent hollow chambers of the profile can then be stiffened. However, with such bracing of adjacent hollow chambers, the drilling and screwing positions must be offset in order to connect the bracing to the masonry. This is difficult to implement in terms of control and production technology.
Zusammenfassend lässt sich festhalten: Konventionelle Fensterprofile mit nachträglicher Metallarmierung besitzen die Nachteile einer schlechten Wärmedämmung und eines hohen Gewichts. Fensterprofile mit ab Werk integrierter Aussteifung sind schwierig zu dimensionieren; eine zusätzliche Armierung ist nur erschwert möglich, insbesondere ist keine einheitliche Schraubposition bei zusätzlicher Armierung gegeben. Je nach Einsatzzweck und Belastung müssen heutzutage Fenster- oder Türkonstruktionen unterschiedlich dimensioniert werden. Beim Einsatz von Stahlarmierungen ist daher nachteiliger Weise eine versetzte Montageachse notwendig.In summary: Conventional window profiles with subsequent metal reinforcement have the disadvantages of poor thermal insulation and high weight. Window profiles with factory-integrated bracing are difficult to dimension; Additional reinforcement is difficult to achieve; in particular, there is no uniform screw position with additional reinforcement. Depending on the intended use and load, window or door constructions nowadays have to be dimensioned differently. When using steel reinforcements, an offset assembly axis is therefore disadvantageously necessary.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Hohlkammerprofil der eingangs genannten Art dahingehend weiterzubilden, dass damit ein faserverstärktes Profil realisierbar ist, in das bei Bedarf eine Metallaussteifung eingeschoben werden kann. Die Bohrachsen für die Montage sollen so platziert oder platzierbar sein, dass ohne und mit Metallaussteifung die gleiche Bohr- und Schraubachse für die Montage zur Anwendung kommen kann. Abhängig von den vorliegenden Anforderungen kann dann eine entsprechende, geeignete Aussteifung zum Einsatz kommen.The invention is therefore based on the object of developing a hollow chamber profile of the type mentioned in such a way that a fiber-reinforced profile can be realized into which a metal stiffener can be inserted if necessary. The drilling axes for assembly should be placed or able to be placed in such a way that the same drilling and drilling axes can be achieved without and with metal reinforcement Screw axle can be used for assembly. Depending on the existing requirements, appropriate, suitable bracing can then be used.
Die Aufgabe wird erfindungsgemäß gelöst durch ein extrudiertes Fenster- oder Tür-Hohlkammerprofil mit den Merkmalen des Anspruchs 1, durch ein System mit den Merkmalen des Anspruchs 13 sowie durch einen Rahmen mit den Merkmalen des Anspruchs 14.The object is achieved according to the invention by an extruded window or door hollow chamber profile with the features of
Vorteilhafte Weiterbildungen des Erfindungsgegenstands sind in den Unteransprüchen definiert.Advantageous developments of the subject matter of the invention are defined in the subclaims.
Erfindungsgemäß ist ein extrudiertes Fenster- oder Tür-Hohlkammerprofil, vorzugsweise mit ab Werk integrierter Aussteifung, mit mindestens einem Befestigungsbereich zur Befestigung des Hohlkammerprofils an einer oder zum Verbinden des Hohlkammerprofils mit einer externen Komponente, insbesondere mit einem Mauerwerk (Baukörper), welcher Befestigungsbereich zur Aufnahme eines randseitig profilierten Befestigungsmittels ausgebildet und vorgesehen ist, welches Hohlkammerprofil einen Zwischenbereich aufweist, der als Armierungskammer zur Aufnahme einer vorzugsweise metallischen Armierung ausgebildet ist, welches Hohlkammerprofil in dem Befestigungsbereich mindestens einen Befestigungskanal aufweist, der senkrecht zu einer Extrusionslängsrichtung des Hohlkammerprofils orientiert ist, welcher Befestigungskanal eine Kanal-Längsachse aufweist, an seinen Enden senkrecht zu der Kanal-Längsachse durch jeweils eine Außenwandung des Hohlkammerprofils verschlossen ist und parallel zu der Kanal-Längsachse seitlich durch Kanal-Seitenwände begrenzt ist, wobei der Befestigungskanal zwischen den beiden Außenwandungen in wenigstens zwei Teil-Befestigungskanäle (oder Schraubkammern) unterteilt ist, welche Teil-Befestigungskanäle in Richtung der Kanal-Längsachse durch wenigstens den Zwischenbereich voneinander beabstandet sind und entlang der Kanal-Längsachse fluchten.According to the invention, an extruded window or door hollow chamber profile, preferably with reinforcement integrated ex works, with at least one fastening area for fastening the hollow chamber profile to or for connecting the hollow chamber profile to an external component, in particular to a masonry (structure), which fastening area is for receiving a fastening means profiled on the edge is designed and provided, which hollow chamber profile has an intermediate region which is designed as a reinforcement chamber for receiving a preferably metallic reinforcement, which hollow chamber profile has at least one fastening channel in the fastening area, which is oriented perpendicular to an extrusion longitudinal direction of the hollow chamber profile, which fastening channel has a Channel longitudinal axis, is closed at its ends perpendicular to the channel longitudinal axis by an outer wall of the hollow chamber profile and is laterally limited parallel to the channel longitudinal axis by channel side walls, the fastening channel between the two outer walls in at least two partial fastening channels (or screw chambers) is divided, which partial fastening channels are spaced apart from one another in the direction of the channel longitudinal axis by at least the intermediate region and are aligned along the channel longitudinal axis.
Bei einem erfindungsgemäßen System aus einem erfindungsgemäßen extrudierten Fenster- oder Tür-Hohlkammerprofil und wenigstens einem randseitig profilierten Befestigungsmittel, vorzugsweise Schraube, ist vorgesehen, dass das Befestigungsmittel entlang der Kanal-Längsachse in den Befestigungskanal und in die Teil-Befestigungskanäle eingebracht ist, wobei die externe Komponente in Verlängerung der Kanal-Längsachse angeordnet oder anzuordnen ist; und/oder dass das Befestigungsmittel quer zu der Kanal-Längsachse in wenigstens einer der Teil-Befestigungskanäle eingebracht ist, wobei die externe Komponente seitlich beabstandet von der Kanal-Längsachse im Bereich einer von den beiden Außenwandungen verschiedenen Stirnseite des Hohlkammerprofils angeordnet oder anzuordnen ist; wobei vorzugsweise ein Außendurchmesser des Befestigungsmittels größer ist als ein lichter Querschnitt der Teil-Befestigungskanäle oder des wenigstens einen der Teil-Befestigungskanäle.In a system according to the invention consisting of an extruded window or door hollow chamber profile according to the invention and at least one edge-profiled fastening means, preferably screw, it is provided that the fastening means is inserted into the fastening channel along the longitudinal axis of the channel and is introduced into the partial fastening channels, the external component being arranged or to be arranged in an extension of the channel's longitudinal axis; and/or that the fastening means is introduced transversely to the channel longitudinal axis in at least one of the partial fastening channels, the external component being arranged or to be arranged laterally spaced apart from the channel longitudinal axis in the region of an end face of the hollow chamber profile that is different from the two outer walls; wherein preferably an outer diameter of the fastening means is larger than a clear cross section of the partial fastening channels or of at least one of the partial fastening channels.
Bei einem erfindungsgemäßen Rahmen für eine Tür oder ein Fenster, der aus mehreren miteinander in Verbindungsbereichen verbundenen, vorzugsweise verschweißten, Abschnitten von erfindungsgemäßen Hohlkammerprofilen gebildet ist, ist vorgesehen, dass in wenigstens einem der Verbindungsbereiche ein vorzugsweise metallisches Verbindungselement, vorzugsweise ein Verbindungswinkel, in zwei miteinander verbundene Hohlkammerprofil-Abschnitte im Bereich des jeweiligen Befestigungskanals eingebracht ist; und/oder dass in den wenigstens einen Zwischenbereich oder in wenigstens einen der Zwischenbereiche ein vorzugsweise metallisches Armierungselement eingesetzt ist.In a frame according to the invention for a door or a window, which is formed from several sections of hollow chamber profiles according to the invention which are connected to one another in connection areas, preferably welded, it is provided that in at least one of the connection areas a preferably metallic connecting element, preferably a connection angle, is connected in two to one another connected hollow chamber profile sections are introduced in the area of the respective fastening channel; and/or that a preferably metallic reinforcing element is inserted into the at least one intermediate region or into at least one of the intermediate regions.
Die vorgeschlagene Konstruktion ist so gestaltet, dass der Schraubenhalt im Profil aufgrund der erfindungsgemäß vorgesehenen Teil-Befestigungskanäle bzw. Schraubkammern auch ohne eine zusätzliche Armierung für standardmäßige Belastungen ausreichend dimensioniert ist. Insbesondere bei auf Querkraft belasteten Montagemitteln (Befestigungsschrauben) konnte ein vergleichbares Niveau an Steifigkeit zu Lösungen mit durchgehendem Schraubkanal ermittelt werden. Querkräfte resultieren etwa durch Belastungen, die am Fenster typischerweise durch Windbelastungen vorkommen.The proposed construction is designed in such a way that the screw hold in the profile is sufficiently dimensioned for standard loads even without additional reinforcement due to the partial fastening channels or screw chambers provided according to the invention. A comparable level of rigidity to solutions with a continuous screw channel could be determined, particularly for mounting devices loaded with shear forces (fastening screws). Transverse forces result from loads that typically occur on windows due to wind loads.
Für besondere Belastungen, etwa bei Einsatz einer Absturzsicherung oder bei einem französischen Balkon, kann zusätzlich in den genannten Zwischenbereich eine (metallische) Armierung in das Profil eingeschoben werden. Die Montagebohrungen verbleiben hierbei vorteilhafter Weise auf derselben Achse und Position.For special loads, such as when using fall protection or a French balcony, a (metallic) reinforcement can also be inserted into the profile in the intermediate area mentioned. The mounting holes advantageously remain on the same axis and position.
Die Verschraubung durchdringt die vorzugsweise im Bereich der Teil-Befestigungskanäle bzw. Schraubkammern vorhandenen (oder durch die Schraubkammern selbst gebildeten) Materialanhäufungen im Profil und die Aussteifung dann gleichermaßen. So kann in Anwendungsbereichen, bei der eine Metallarmierung erforderlich ist, das Profil gezielt und partiell ausgesteift werden, ohne den Fertigungsablauf der Bohrungen und Verschraubung ändern zu müssen. Die Armierungswirkung kann somit besonders effizient dimensioniert werden.The screw connection then penetrates the material accumulations in the profile, which are preferably present in the area of the partial fastening channels or screw chambers (or are formed by the screw chambers themselves), and the stiffening equally. In areas of application where metal reinforcement is required, the profile can be specifically and partially stiffened without having to change the production process for the holes and screw connections. The reinforcement effect can therefore be dimensioned particularly efficiently.
Der Begriff "Schraubkammer" beinhaltet bevorzugt, dass die betreffenden Kammern (bei einem Querschnitt durch das Profil) ringsum von Profilmaterial (Stegen) umgeben bzw. eingeschlossen sind. Die Schraubkammern stellen somit bereits für sich genommen Materialanhäufungen im Profil dar, was die Stabilität erhöht.The term “screw chamber” preferably means that the chambers in question (in a cross section through the profile) are surrounded or enclosed all around by profile material (webs). The screw chambers themselves represent accumulations of material in the profile, which increases stability.
Eine spezielle Weiterbildung des erfindungsgemäßen Hohlkammerprofils sieht vor, dass die Kanal-Seitenwände in dem Zwischenbereich einen größeren Abstand zueinander aufweisen als in einem Bereich der Teil-Befestigungskanäle. Auf diese Weise kann in dem Zwischenbereich ausreichend Platz zum Einbringen eines geeignet dimensionierten Armierungsprofils geschaffen werden. Insbesondere treten die Kanal-Seitenwände in dem Zwischenbereich zumindest soweit zurück, dass keine Wechselwirkung mit dem Montage-/Befestigungsmittel mehr auftritt.A special development of the hollow chamber profile according to the invention provides that the channel side walls are at a greater distance from one another in the intermediate region than in an area of the partial fastening channels. In this way, sufficient space can be created in the intermediate area for the introduction of a suitably sized reinforcement profile. In particular, the channel side walls recede in the intermediate region at least to such an extent that there is no longer any interaction with the mounting/fastening means.
Eine andere Weiterbildung des erfindungsgemäßen Hohlkammerprofils sieht vor, dass innerhalb der Teil-Befestigungskanäle, vorzugsweise an wenigstens einer der beiden Außenwandungen, eine Materialanhäufung oder eine Verdickung, insbesondere der betreffenden Außenwandung, vorgesehen ist. Dadurch kann die bereits angesprochene Haltewirkung noch verbessert werden. Allerdings stellen auch die genannten Teil-Befestigungskanäle selbst gewisse Materialanhäufungen dar, worauf bereits hingewiesen wurde. Durch die genannten zusätzlichen Materialanhäufungen bzw. Verdickungen kann diese Wirkung noch verbessert werdenAnother development of the hollow chamber profile according to the invention provides that an accumulation of material or a thickening, in particular of the relevant outer wall, is provided within the partial fastening channels, preferably on at least one of the two outer walls. As a result, the holding effect already mentioned can be improved even further. However, the partial fastening channels themselves also represent certain accumulations of material, as has already been pointed out. This effect can be further improved by the additional material accumulations or thickenings mentioned
Bei einer wieder anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist vorgesehen, dass die Kanal-Seitenwände an ihrer wenigstens einen der Teil-Befestigungskanäle begrenzenden Innenseite Vorsprünge aufweisen.In yet another development of the hollow chamber profile according to the invention, it is provided that the channel side walls have projections on their inside which delimits at least one of the partial fastening channels.
Solche Vorsprünge können mit einem in den Kanal eingebrachten Befestigungsmittel mechanisch zusammenwirken, um die Befestigungswirkung zu verbessern.Such projections can interact mechanically with a fastener introduced into the channel in order to improve the fastening effect.
Um diesen Effekt noch zu erhöhen, kann bei entsprechender Weiterbildung des erfindungsgemäßen Hohlkammerprofils vorgesehen sein, dass zwischen Vorsprüngen, die von verschiedenen Kanal-Seitenwänden ausgehen, in einer Querrichtung quer zu der Kanal-Längsachse ein lichter Höchstabstand vorgesehen ist, welcher lichte Höchstabstand vorzugsweise 2 mm nicht übersteigt; und/oder dass zwischen zwei in einer Längsrichtung entlang der Kanal-Längsachse benachbarten Vorsprüngen ein Höchstabstand vorgesehen ist, welcher Höchstabstand vorzugsweise 2 mm oder weniger beträgt; und/oder dass zwischen einem Vorsprung und einer dem Vorsprung gegenüberliegenden Kanal-Seitenwand ein Höchstabstand von vorzugsweise 2 mm oder weniger vorgesehen ist. Auf diese Weise lässt sich insbesondere sicherstellen, dass ein in den Kanal eingebrachtes Befestigungsmittel mit den genannten Vorsprüngen zusammenwirkt. Die angegebenen Werte haben sich aus Sicht der Anmelderin als besonders gut geeignet erwiesen.In order to further increase this effect, with a corresponding development of the hollow chamber profile according to the invention, it can be provided that a maximum clear distance is provided between projections that extend from different channel side walls in a transverse direction transverse to the channel longitudinal axis, which maximum clear distance is preferably 2 mm does not exceed; and/or that a maximum distance is provided between two projections adjacent in a longitudinal direction along the channel longitudinal axis, which maximum distance is preferably 2 mm or less; and/or that a maximum distance of preferably 2 mm or less is provided between a projection and a channel side wall opposite the projection. In this way, it can be ensured in particular that a fastening means introduced into the channel interacts with the projections mentioned. From the applicant's point of view, the specified values have proven to be particularly suitable.
In diesem Zusammenhang kann weiterhin noch vorgesehen sein, dass von verschiedenen Kanal-Seitenwänden ausgehende Vorsprünge in Längsrichtung entlang der Kanal-Längsachse versetzt oder auf gleicher Höhe angeordnet sind. Hierdurch lässt sich die Befestigungswirkung an unterschiedliche Anforderungen anpassen.In this context, it can also be provided that projections emanating from different channel side walls are offset in the longitudinal direction along the channel longitudinal axis or are arranged at the same height. This allows the fastening effect to be adapted to different requirements.
Bei wieder einer anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils kann vorgesehen sein, dass wenigstens einige der Vorsprünge sich unter einem Winkel bezüglich der betreffenden Kanal-Seitenwände erstrecken, welcher Winkel bevorzugt entweder 90° beträgt oder von 90° abweicht und bevorzugt zwischen 30° und 60° beträgt, höchst vorzugsweise 45°, wobei vorzugsweise auf gleicher Höhe angeordnete Vorsprünge gleiche Winkel aufweisen. Auch dies kann zu einer verbesserten Befestigungswirkung beitragen.In yet another development of the hollow chamber profile according to the invention, it can be provided that at least some of the projections extend at an angle with respect to the relevant channel side walls, which angle is preferably either 90° or deviates from 90° and is preferably between 30° and 60° , most preferably 45°, with projections arranged at the same height preferably having the same angles. This can also contribute to an improved fastening effect.
Bei dem erfindungsgemäßen Hohlkammerprofil ist vorgesehen, dass der Zwischenbereich als Armierungskammer zur Aufnahme einer vorzugsweise metallischen Armierung ausgebildet ist. Auf die besonderen Vorteile einer solchen Ausgestaltung wurde weiter oben bereits detailliert hingewiesen. Hiermit kann insbesondere verbunden sein, dass der Zwischenbereich hinreichend groß dimensioniert ausgebildet ist, um darin eine statisch wirksame Armierung aufnehmen zu können. Dies kann implizieren, dass in Richtung der Kanal-Längsachse ein deutlicher Abstand zwischen den Teil-Befestigungskanälen oder Schraubkammern existiert bzw. dass die Kanal-Seitenwände in dem Zwischenbereich deutlich zurückspringen, verglichen mit den Teil-Befestigungskanälen.In the hollow chamber profile according to the invention it is provided that the intermediate region is designed as a reinforcement chamber for receiving a preferably metallic reinforcement. On the special advantages of such The design has already been explained in detail above. This can in particular mean that the intermediate region is designed to be sufficiently large in order to be able to accommodate a statically effective reinforcement. This can imply that in the direction of the channel longitudinal axis there is a significant distance between the partial fastening channels or screw chambers or that the channel side walls in the intermediate region stand back significantly compared to the partial fastening channels.
In der Praxis kann die Armierungskammer typische Abmessungen zwischen 20 bis 50 mm in Höhe und Breite aufweisen. Die Schraubkammern können eine Breite von vorzugsweise 6 bis 8 mm (Kammerlichte) und eine Höhe von 3 bis 10 mm aufweisen.In practice, the reinforcement chamber can have typical dimensions between 20 and 50 mm in height and width. The screw chambers can have a width of preferably 6 to 8 mm (chamber width) and a height of 3 to 10 mm.
Bei noch einer anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils kann vorgesehen sein, dass die Kanal-Seitenwände im Bereich wenigstens eines Teil-Befestigungskanals zumindest einseitig, vorzugsweise beidseitig, quer zur Extrusionslängsrichtung seitlich abgestützt sind. Dies verbessert die Stabilität der Teil-Befestigungskanäle beim Einbringen eines Befestigungsmittels und erhöht somit die Haltewirkung.In yet another development of the hollow chamber profile according to the invention, it can be provided that the channel side walls are laterally supported in the area of at least one partial fastening channel at least on one side, preferably on both sides, transversely to the longitudinal direction of extrusion. This improves the stability of the partial fastening channels when a fastener is inserted and thus increases the holding effect.
Bei wieder einer anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils kann vorgesehen sein, dass die Abstützung wenigstens einer Kanal-Seitenwand unter einem Winkel von 90 Grad bezüglich der Kanal-Längsachse erfolgt. In der Praxis ergibt sich so eine besonders gute Stabilisierungswirkung.In another further development of the hollow chamber profile according to the invention, it can be provided that at least one channel side wall is supported at an angle of 90 degrees with respect to the longitudinal axis of the channel. In practice, this results in a particularly good stabilization effect.
Zusätzlich oder alternativ kann bei einer anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils jedoch auch vorgesehen sein, dass die Abstützung wenigstens einer Kanal-Seitenwand unter einem Winkel abweichend von 90 Grad bezüglich der Kanal-Längsachse erfolgt. Dies kann insbesondere Vorteile hinsichtlich des benötigten Materialeinsatzes bei der Fertigung des Hohlkammerprofils haben.Additionally or alternatively, in another development of the hollow chamber profile according to the invention, it can also be provided that at least one channel side wall is supported at an angle other than 90 degrees with respect to the channel longitudinal axis. This can have particular advantages with regard to the use of material required in the production of the hollow chamber profile.
Eine andere, vorteilhafte Weiterbildung des erfindungsgemäßen Hohlkammerprofils sieht vor, dass wenigstens ein Teil-Befestigungskanal als Ansatz an einen durchgängigen Quersteg des Hohlkammerprofil ausgebildet ist, vorzugsweise in Montagerichtung unterhalb bzw. außerhalb des betreffenden Querstegs. Eine solche Ausgestaltung hat sich in der Praxis als besonders widerstandsfähig erwiesen. Außerdem kann durch den betreffenden Quersteg eine thermisch wirksame zusätzliche Isolierkammer innerhalb des Profils geschaffen werden, was entsprechende energetische Vorteile mit sich bringt.Another advantageous development of the hollow chamber profile according to the invention provides that at least one partial fastening channel is designed as an attachment to a continuous transverse web of the hollow chamber profile, preferably in the assembly direction below or outside the relevant crossbar. Such a design has proven to be particularly robust in practice. In addition, the crossbar in question can create a thermally effective additional insulating chamber within the profile, which brings corresponding energetic advantages.
Schließlich kann bei einer Weiterbildung des erfindungsgemäßen Hohlkammerprofils noch vorgesehen sein, dass der Befestigungskanal zumindest teilweise mit einem festen oder pastösen Material gefüllt ist, vorzugsweise mit einem thermisch wirksamen Dämmstoff und/oder einem Befestigungsmaterial, insbesondere einem Dämmschaum oder Injektionsmörtel. Hierdurch lassen sich sowohl die thermische Isoliereigenschaften als auch die Haltewirkung nochmals verbessern.Finally, in a further development of the hollow chamber profile according to the invention, it can also be provided that the fastening channel is at least partially filled with a solid or pasty material, preferably with a thermally effective insulating material and/or a fastening material, in particular an insulating foam or injection mortar. This allows both the thermal insulation properties and the holding effect to be further improved.

Der Befestigungskanal 7 ist nämlich zwischen den beiden Außenwandungen 1a, 1b in vorliegend zwei Teil-Befestigungskanäle 7.1 und 7.2 unterteilt, welche Teil-Befestigungskanäle 7.1, 7.2 (vorliegend auch als Schraubkammern bezeichnet) in Richtung der Kanal-Längsachse 9 durch wenigstens einen Zwischenbereich 10 voneinander beabstandet sind. Der Zwischenbereich 10 ist ausreichend groß dimensioniert, dass darin eine zusätzliche Armierung einbringbar ist (vergleiche Bezugszeichen 2 in
Dadurch ergibt sich mit Blick auf die genannten Kanal-Seitenwände 7a, 7b folgendes Bild: die Kanal-Seitenwand 7a bildet zunächst die linke Begrenzung des (oberen) Teil-Befestigungskanals 7.1, erstreckt sich dann parallel zu der Außenwandung 1a weiter nach links, weg von der Kanal-Längsachse 9, knickt anschließend parallel zur Kanal-Längsachse 9 nach unten ab und geht dann in die Außenwandung 1b über. Die Kanal-Seitenwand 7b bildet dagegen zunächst die rechte Begrenzung des (oberen) Teil-Befestigungskanals 7.1, erstreckt sich dann schräg nach oben in Richtung der Außenwandung 1a und wird dann gebildet durch die (rechte) Aussteifung 5 bzw. durch die Außenwandung 1b.This results in the following picture with a view to the
In dem Zwischenbereich 10 stehen die Befestigungsschraube 3 und die Kanal-Seitenwände 7a, 7b nicht in Wechselwirkung.In the
Alternativ ließe sich auch formulieren, dass der Befestigungskanal 7 nur im Bereich der genannten Teil-Befestigungskanäle 7.1, 7.2 behauptet definierte Kanal-Seitenwände aufweist. In dem genannten Zwischenbereich 10 bzw. gegebenenfalls in weiteren Zwischenbereichen (siehe unten) existiert demnach überhaupt keine Kanal-Seitenwand im engeren Sinne, obwohl natürlich innerhalb des Hohlkammerprofils 1 durchgängige Strukturen parallel zu der Kanal-Längsachse 9 existieren. Letztendlich kommt es also darauf an, dass entlang der Kanal-Längsachse 9 zumindest zwei fluchtende Teil-Befestigungskanäle 7.1, 7.2 existieren, die nicht zusammenhängend ausgebildet sind. Dazwischen befindet sich der genannte Zwischenbereich 10, in dem das Befestigungsmittel 3 das Hohlkammerprofil 1 durchquert bzw. durchqueren kann, ohne mit irgendwelchen Strukturen innerhalb des Hohlkammerprofils 1 in Wechselwirkung zu treten. Dies wird durch den alternativ bzw. synonym verwendeten Begriff "Schraubkammer" gut zum Ausdruck gebracht, weil hierbei anklingt, dass es sich bei den Teil-Befestigungskanälen um (ab-)geschlossene Strukturen innerhalb des Hohlkammerprofils 1 handelt. Dies ergibt sich insbesondere auch aus den Figuren und gilt für alle beschriebenen und gezeigten Ausgestaltungen der Erfindung.Alternatively, it could also be formulated that the
Die obere Schraubkammer bzw. der Teil-Befestigungskanal 7.1 ist zwischen der Außenwandung 1a und einem parallel zu der Außenwandung 1a angeordneten Quersteg 11 ausgebildet. Die untere Schraubkammer bzw. Teil-Befestigungskanal 7.2 ist gewissermaßen als Ansatz unterhalb des Hohlkammerprofils 1 (unterhalb der (Profil-)Außenwandung 1b) ausgebildet. Die Außenwandung 1a besitzt innerhalb des Hohlkammerprofils 1 eine Verdickung bzw. Materialanhäufung 12, während innerhalb des Teil-Befestigungskanals 7.2 Vorsprünge 13 an den Kanal-Seitenwänden vorgesehen sind, die sich etwa quer zur Kanal-Längsachse 9 erstrecken. Ein lichter Abstand der Kanal-Seitenwände 7a, 7b bzw. der Vorsprünge 13 im Bereich der Schraubkammern ist derart auf das Montage- bzw. Befestigungsmittel 3 abgestimmt, dass dieses mit seiner randseitigen Profilierung 3a in die Kanal-Seitenwände bzw. die Vorsprünge 13 eingreift.The upper screw chamber or the partial fastening channel 7.1 is arranged between the
Grundsätzlich kann das Befestigungsmittel 3 auch in der Extrusionslängsrichtung 8 des Hohlkammerprofils 1 in die Schraubkammern 7.1, 7.2 eingeschraubt werden, beispielsweise um zusätzliche Elemente, wie Beschläge oder dergleichen, an dem Hohlkammerprofil 1 zu befestigen. Dies gilt auch für die Schraubkammern gemäß den weiter unten erläuterten
