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 already have an integrated reinforcement ex works and comprises 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 at the edge.
- the hollow chamber profile has at least one fastening channel, which is oriented perpendicular to a longitudinal direction of extrusion 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 with claim 14 to a system made up 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 that are connected to one another in connection areas, preferably welded.
- a generic hollow profile is, for example, from DE 10 2020 108 412.9 , the EP 2 079 895 B1 or the DE 43 38 181 C1 known.
- a hollow chamber profile with a continuous fastening channel is known from this prior art, 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 reinforced depending on the existing requirements and the expected loads.
- Conventional window profiles have specially dimensioned hollow chambers.
- Metal profiles are inserted and screwed into these chambers to increase the stability of the window or door.
- Such chambers are referred to as reinforcement chambers.
- reinforcement chambers Although only windows were mentioned 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.
- 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 connected to the masonry (reveal) of the building or to any other external components at defined intervals using assembly or fastening means, such as spacer assembly screws.
- assembly or fastening means such as spacer assembly screws.
- the screw 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 with the help of screw channels, for example.
- a window frame is that part of a window or door frame that is firmly connected to the masonry.
- the moving part of the window or door is called the sash or sash frame.
- neighboring hollow chambers of the profile can then be reinforced.
- the drilling and screwing positions have to be offset in order to connect the stiffening to the masonry. This is difficult to implement in terms of control and production technology.
- the invention is therefore based on the object of further developing a hollow chamber profile of the type mentioned at the outset in such a way that a fiber-reinforced profile can be realized with it, into which a metal stiffener can be inserted if necessary.
- the drilling axes for assembly should be placed or placeable in such a way that the same drilling and screwing axis can be used for assembly with and without metal reinforcement. Depending on the requirements at hand, a corresponding, suitable reinforcement 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 masonry (structure), which fastening area is to be accommodated a fastening means profiled on the edge is formed and provided, which hollow chamber profile has at least one fastening channel in the fastening area, which is oriented perpendicularly to a longitudinal direction of extrusion of the hollow chamber profile, which fastening channel has a longitudinal channel axis, at its ends perpendicular to the longitudinal channel axis through an outer wall in each case of the hollow chamber profile is closed and is laterally delimited parallel to the longitudinal axis of the channel by channel side walls, characterized in that the fastening channel between the two outer walls in at least between ei partial fastening channels (or screw chambers), which partial fastening channels are spaced apart from one another in the direction of the longitudinal channel axis by at least one intermediate area
- a fastening means is introduced along the longitudinal axis of the channel into the fastening channel and into the partial fastening channels, the external component being arranged or to be arranged in an extension of the longitudinal axis of the channel; and/or that the fastening means is inserted transversely to the longitudinal axis of the channel in at least one of the partial fastening channels, the external component being arranged or to be arranged at a lateral distance from the longitudinal axis of the channel in the area of an end face of the hollow chamber profile that is different from the two outer walls; wherein an outer diameter of the fastening means is preferably larger than a clear cross section of the partial fastening channels or of the at least one of the partial fastening channels.
- a frame according to the invention for a door or a window which consists of several interconnected in connection areas, preferably welded, sections of hollow chamber profiles according to the invention is formed, it is provided that in at least one of the connection areas preferably a metallic connecting element, preferably a connecting angle, is introduced into two interconnected hollow chamber profile sections in the area of the respective fastening channel; and/or that a preferably metallic reinforcement 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 in the case of assembly means (fastening screws) subjected to transverse forces. Lateral forces result, for example, from loads that typically occur on the window due to wind loads.
- a (metallic) reinforcement can also be pushed 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 accumulations of material in the profile, which are preferably present in the area of the partial attachment channels or screw chambers (or formed by the screw chambers themselves), and the stiffening in the same way.
- the profile can be selectively and partially stiffened without having to change the production process for drilling and screwing. The reinforcement effect can thus be dimensioned particularly efficiently.
- screw chamber preferably means that the relevant chambers (in the case of a cross section through the profile) are surrounded or enclosed on all sides by profile material (webs). The screw chambers therefore already 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 a region of the partial fastening channels. In this way, sufficient space can be created in the intermediate area for introducing a suitably dimensioned reinforcement profile.
- the channel side walls in the intermediate area recede at least to such an extent that there is no longer any interaction with the assembly/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 further improved.
- the partial fastening channels mentioned 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 inner side, which delimits at least one of the partial fastening channels. Such projections can mechanically interact with a fastener introduced into the channel to improve the fastening effect.
- a maximum clear distance is provided between projections that emanate from different channel side walls in a transverse direction transverse to the longitudinal channel axis, which maximum clear distance is preferably 2 mm does not exceed; and/or that a maximum distance is provided between two adjacent projections in a longitudinal direction along the longitudinal axis of the channel, which maximum distance is preferably 2 mm or less; and/or that between a projection and a channel side wall opposite the projection Maximum distance of preferably 2 mm or less is provided.
- 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.
- projections originating 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 preferably arranged at the same height having the same angle. This too can contribute to an improved fastening effect.
- the intermediate area is designed as a reinforcement chamber for receiving a preferably metallic reinforcement.
- the intermediate area is dimensioned to be sufficiently large in order to be able to accommodate a statically effective reinforcement therein. This can imply that in the direction of the longitudinal axis of the channel there is a clear distance between the partial fastening channels or screw chambers or that the channel side walls in the intermediate region are set back significantly compared to the partial fastening channels.
- the armor chamber can have typical dimensions of between 20 and 50 mm in height and width.
- the screw chambers can have a width of preferably 6 to 8 mm (chamber clearance) and a height of 3 to 10 mm.
- the channel side walls in the area of at least one partial fastening channel are laterally supported at least on one side, preferably on both sides, transverse to the longitudinal direction of extrusion. This improves the stability of the partial fastening channels when introducing a fastening means and thus increases the holding effect.
- At least one channel side wall is supported at an angle of 90 degrees with respect to the channel longitudinal axis. In practice, this results in a particularly good stabilization effect.
- the hollow chamber profile can also be provided that at least one side wall of the duct is supported at an angle deviating from 90 degrees with respect to the longitudinal axis of the duct.
- this can have advantages with regard to the required use of material 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 crosspiece of the hollow chamber profile, preferably below or outside the relevant crosspiece in the assembly direction.
- a thermally effective additional insulating chamber can be created within the profile by the transverse web in question, which entails corresponding energetic advantages.
- the fastening channel is at least partially filled with a solid or pasty material, preferably with a thermally active insulating material and/or a fastening material, in particular an insulating foam or injection mortar.
- a solid or pasty material preferably with a thermally active insulating material and/or a fastening material, in particular an insulating foam or injection mortar.
- 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 fastening the window profile 1 to a structure or building 4.
- a mounting means 3 fastening screw
- FIG 2 shows a cross section through a hollow chamber profile 1 according to the invention.
- the hollow chamber profile 1 has a reinforcement integrated ex works, in particular made of a fiber composite material, at reference number 5 .
- the hollow chamber profile 1 has a fastening area at reference number 6, which is used to fasten the hollow chamber profile 1 to or to connect the hollow chamber profile 1 to an external component, in the present case with the structure 4, which is arranged in the assembly direction (screw direction) below or outside of the hollow chamber profile 1.
- the fastening area 6 is designed and provided for receiving a fastening means profiled on the edge, namely the fastening screw 3, as can be easily seen from the figure.
- the hollow chamber profile 1 has in the fastening area 6 a fastening channel 7 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 figure 2 is drawn as a dashed line. Furthermore, the fastening channel 7 is closed at its ends perpendicular to the longitudinal channel axis 9 by an outer wall of the hollow chamber profile 1 in each case. These outer walls are in figure 2 are provided with the reference numerals 1a and 1b, respectively. Parallel to the longitudinal axis 9 of the channel, the fastening channel 7 is delimited laterally by channel side walls 7a, 7b.
- the fastening channel 7 is divided between the two outer walls 1a, 1b in the present case into two partial fastening channels 7.1 and 7.2, which partial fastening channels 7.1, 7.2 (also referred to here as screw chambers) are separated from one another in the direction of the longitudinal channel axis 9 by at least one intermediate area 10 are spaced.
- the intermediate area 10 is dimensioned sufficiently large that an additional reinforcement can be introduced into it (compare reference number 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 parallel to the channel longitudinal axis 9 down 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 in the direction of the outer wall 1a and is then formed by the (right) reinforcement 5 or by the outer wall 1b.
- the fastening channel 7 only has defined channel side walls in the area of the named partial fastening channels 7.1, 7.2.
- intermediate area 10 or possibly in further intermediate areas (see below) there is therefore no channel side wall in the narrower sense, although of course continuous structures parallel to the channel longitudinal axis 9 exist within the hollow chamber profile 1 .
- the upper screw chamber or the partial fastening channel 7.1 is formed between the outer wall 1a and a transverse web 11 arranged parallel to the outer wall 1a.
- the lower screw chamber or part-fastening channel 7.2 is designed to a certain extent as a projection 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 side walls of the channel within the part-fastening channel 7.2, which extend approximately transversely to the longitudinal axis 9 of the channel.
- a clearance between the channel side walls 7a, 7b and the projections 13 in the area of the screw chambers is matched to the mounting or fastening means 3 in such a way that it engages in the channel side walls or the projections 13 with its edge-side profile 3a.
- the fastening means 3 can also be screwed into the screw chambers 7.1, 7.2 in the extrusion longitudinal direction 8 of the hollow chamber profile 1 are, for example, to attach additional elements such as fittings or the like to the hollow chamber profile 1. This also applies to the screw chambers according to those explained below Figures 4 to 7 .
- figure 3 shows the same hollow chamber profile 1 as in figure 2 , but with introduced into said intermediate region 10 metallic reinforcement 2.
- the longitudinal axis 9 of the channel has remained unchanged, so that the direction of introduction of the mounting or fastening means 3 has also remained unchanged.

Die Erfindung betrifft ein extrudiertes Fenster- oder Tür-Hohlkammerprofil gemäß dem Oberbegriff des Anspruchs 1. Ein solches Hohlkammerprofil kann vorzugsweise bereits ab Werk eine integrierte Aussteifung aufweisen und umfasst mindestens einen Befestigungsbereich zur Befestigung des Hohlkammerprofils an einer oder zum Verbinden des Hohlkammerprofils mit einer externen Komponente, welcher Befestigungsbereich zur Aufnahme eines randseitig profilierten Befestigungsmittels ausgebildet und vorgesehen ist. Das Hohlkammerprofil weist in dem Befestigungsbereich mindestens einen Befestigungskanal auf, der senkrecht zu einer Extrusionslängsrichtung des Hohlkammerprofils orientiert ist. Der Befestigungskanal besitzt eine Kanal-Längsachse, ist an seinen Enden senkrecht zu der Kanal-Längsachse durch jeweils eine Außenwandung des Hohlkammerprofils verschlossen und ist parallel zu der Kanal-Längsachse seitlich durch Kanal-Seitenwände begrenzt.The invention relates to an extruded window or door hollow chamber profile according to the preamble of
Die Erfindung betrifft außerdem mit dem Anspruch 14 ein System aus einem erfindungsgemäßen extrudierten Fenster- oder Tür-Hohlkammerprofil und wenigstens einem randseitig profilierten Befestigungsmittel, vorzugsweise Schraube.The invention also relates with claim 14 to a system made up 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.
Mit dem Anspruch 15 betrifft die Erfindung weiterhin einen Rahmen für eine Tür oder ein Fenster, der aus mehreren miteinander in Verbindungsbereichen verbundenen, vorzugsweise verschweißten, Abschnitten von erfindungsgemäßen Hohlkammerprofilen gebildet ist.With
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 reinforced depending on the existing requirements and the expected loads. Conventional window profiles have specially dimensioned hollow chambers. Metal profiles are inserted and screwed into these chambers to increase the stability of the window or door. Such chambers are referred to as reinforcement chambers. Although only windows were mentioned 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 structure. New constructions with fiber-reinforced components or with thermally separated stiffeners can improve the thermal insulation considerably. Due to the strongly varying loads depending on the installation location and application, a precise dimensioning of the reinforcements integrated in the profile ex works is very imprecise. The stiffening is therefore often oversized or undersized 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 connected to the masonry (reveal) of the building or to any other external components at defined intervals using assembly or fastening means, such as spacer assembly screws. With conventional solutions, the screw 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 with the help of screw channels, for example.
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 no additional reinforcement can be used in this area. This will the area of application of correspondingly designed blind frame profiles is severely limited. A window frame is that part of a window or door frame that is firmly connected to the masonry. The moving 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, neighboring hollow chambers of the profile can then be reinforced. However, with such a stiffening of adjacent hollow chambers, the drilling and screwing positions have to be offset in order to connect the stiffening 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, it can be said that conventional window profiles with subsequent metal reinforcement have the disadvantages of poor thermal insulation and high weight. Window profiles with factory-integrated reinforcement are difficult to dimension; additional reinforcement is only possible with difficulty, in particular there is no uniform screw position with additional reinforcement. Depending on the application and load, window or door constructions have to be dimensioned differently today. When using steel reinforcements, an offset mounting 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 further developing a hollow chamber profile of the type mentioned at the outset in such a way that a fiber-reinforced profile can be realized with it, into which a metal stiffener can be inserted if necessary. The drilling axes for assembly should be placed or placeable in such a way that the same drilling and screwing axis can be used for assembly with and without metal reinforcement. Depending on the requirements at hand, a corresponding, suitable reinforcement 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 14 sowie durch einen Rahmen mit den Merkmalen des Anspruchs 15.The object is achieved according to the invention by an extruded window or door hollow chamber profile having the features of
Vorteilhafte Weiterbildungen des Erfindungsgegenstands sind in den Unteransprüchen definiert.Advantageous developments of the subject of the invention are defined in the dependent claims.
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 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, dadurch gekennzeichnet, dass 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 einen Zwischenbereich voneinander beabstandet sind.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 masonry (structure), which fastening area is to be accommodated a fastening means profiled on the edge is formed and provided, which hollow chamber profile has at least one fastening channel in the fastening area, which is oriented perpendicularly to a longitudinal direction of extrusion of the hollow chamber profile, which fastening channel has a longitudinal channel axis, at its ends perpendicular to the longitudinal channel axis through an outer wall in each case of the hollow chamber profile is closed and is laterally delimited parallel to the longitudinal axis of the channel by channel side walls, characterized in that the fastening channel between the two outer walls in at least between ei partial fastening channels (or screw chambers), which partial fastening channels are spaced apart from one another in the direction of the longitudinal channel axis by at least one intermediate area.
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 fastening means profiled on the edge, preferably a screw, it is provided that the
fastening means is introduced along the longitudinal axis of the channel into the fastening channel and into the partial fastening channels, the external component being arranged or to be arranged in an extension of the longitudinal axis of the channel; and/or that the fastening means is inserted transversely to the longitudinal axis of the channel in at least one of the partial fastening channels, the external component being arranged or to be arranged at a lateral distance from the longitudinal axis of the channel in the area of an end face of the hollow chamber profile that is different from the two outer walls; wherein an outer diameter of the fastening means is preferably larger than a clear cross section of the partial fastening channels or of the 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 consists of several interconnected in connection areas, preferably welded, sections of hollow chamber profiles according to the invention is formed, it is provided that in at least one of the connection areas
preferably a metallic connecting element, preferably a connecting angle, is introduced into two interconnected hollow chamber profile sections in the area of the respective fastening channel; and/or that a preferably metallic reinforcement 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 in the case of assembly means (fastening screws) subjected to transverse forces. Lateral forces result, for example, from loads that typically occur on the window 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 pushed into the profile in the intermediate area mentioned. In this case, 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 accumulations of material in the profile, which are preferably present in the area of the partial attachment channels or screw chambers (or formed by the screw chambers themselves), and the stiffening in the same way. In areas of application where metal reinforcement is required, the profile can be selectively and partially stiffened without having to change the production process for drilling and screwing. The reinforcement effect can thus 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 relevant chambers (in the case of a cross section through the profile) are surrounded or enclosed on all sides by profile material (webs). The screw chambers therefore already 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 a region of the partial fastening channels. In this way, sufficient space can be created in the intermediate area for introducing a suitably dimensioned reinforcement profile. In particular, the channel side walls in the intermediate area recede at least to such an extent that there is no longer any interaction with the assembly/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 further improved. However, the partial fastening channels mentioned 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. Solche Vorsprünge können mit einem in den Kanal eingebrachten Befestigungsmittel mechanisch zusammenwirken, um die Befestigungswirkung zu verbessern.In yet another further development of the hollow chamber profile according to the invention, it is provided that the channel side walls have projections on their inner side, which delimits at least one of the partial fastening channels. Such projections can mechanically interact with a fastener introduced into the channel 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 further development of the hollow chamber profile according to the invention, it can be provided that a maximum clear distance is provided between projections that emanate from different channel side walls in a transverse direction transverse to the longitudinal channel axis, which maximum clear distance is preferably 2 mm does not exceed; and/or that a maximum distance is provided between two adjacent projections in a longitudinal direction along the longitudinal axis of the channel, which maximum distance is preferably 2 mm or less; and/or that between a projection and a channel side wall opposite the projection Maximum distance of preferably 2 mm or less is provided. 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 originating 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 preferably arranged at the same height having the same angle. This too can contribute to an improved fastening effect.
Bei einer äußerst vorteilhaften Weiterbildung des erfindungsgemäßen Hohlkammerprofils 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 an extremely advantageous development of the hollow chamber profile according to the invention, it is provided that the intermediate area is designed as a reinforcement chamber for receiving a preferably metallic reinforcement. The particular advantages of such an embodiment have already been pointed out in detail above. In particular, this can mean that the intermediate area is dimensioned to be sufficiently large in order to be able to accommodate a statically effective reinforcement therein. This can imply that in the direction of the longitudinal axis of the channel there is a clear distance between the partial fastening channels or screw chambers or that the channel side walls in the intermediate region are set 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 armor chamber can have typical dimensions of between 20 and 50 mm in height and width. The screw chambers can have a width of preferably 6 to 8 mm (chamber clearance) 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 in the area of at least one partial fastening channel are laterally supported at least on one side, preferably on both sides, transverse to the longitudinal direction of extrusion. This improves the stability of the partial fastening channels when introducing a fastening means 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 yet another 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 channel longitudinal axis. 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 side wall of the duct is supported at an angle deviating from 90 degrees with respect to the longitudinal axis of the duct. In particular, this can have advantages with regard to the required use of material 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 crosspiece of the hollow chamber profile, preferably below or outside the relevant crosspiece in the assembly direction. Such a configuration has proven to be particularly robust in practice. In addition, a thermally effective additional insulating chamber can be created within the profile by the transverse web in question, which entails 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 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 active insulating material and/or a fastening material, in particular an insulating foam or injection mortar. As a result, both the thermal insulating properties and the holding effect can 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
The
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 of the mentioned
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 stated 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 formed 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
