Abstract

The hollow box profile (1) has a steel strip which is reshaped roughly into a cuboid. The strip has stamped holes, and has longitudinal edges which are connected to one another. The edges of the strip butt against one another without overlapping, and the four edges (6) of the profile are rounded and stiffened. The rounding and stiffening may be achieved by hollow mouldings or crimps on the edges. At least the broad sides (2,2') of the profile may have crimps (8) which bulge outwards, and which run parallel to the edges.

Description

Die Erfindung betrifft ein Hohlkastenprofil, das insbesondere für in Modulbauweise herstellbare und leicht wieder versetzbare Raumtrennwandsysteme vorgesehen und geeignet ist und das aus im wesentlichen quaderförmig umgeformtem, mit Lochstanzungen versehenem Bandstahl besteht.The invention relates to a hollow box profile, which is provided and suitable in particular for modular partitioning and easily replaceable room partition systems, and which consists of essentially cuboid-shaped steel strip provided with punched holes.

Raumtrennwandsysteme der hier in Rede stehenden Art bestehen im allgemeinen aus einer tragenden Pfosten-Riegel-Konstruktion, wobei das genannte Hohlkastenprofil sowohl als Pfosten wie auch als Riegel eingesetzt werden kann, und aus Wand-, Fenster- und Türmodulen, die an der tragenden Konstruktion vorzugsweise lösbar befestigt sind, wobei die einzelnen Module aus Holz, Kunststoff, Holzverbundwerkstoffen, Metall oder Glas bestehen können. Dem für die Errichtung der tragenden Konstruktion verwendeten Hohlkastenprofil kommt dabei eine entscheidende Bedeutung zu, sowohl hinsichtlich der mechanischen Stabilität, insbesondere der Verwindungssteifigkeit, als auch hinsichtlich der Brand- und Schallschutzerfordernisse, denen diese hauptsächlich im gewerblichen Bereich eingesetzten Raumtrennwandsysteme entsprechen müssen.Room partition systems of the type in question here generally consist of a load-bearing mullion-transom construction, the hollow box profile mentioned being able to be used both as a mullion and a transom, and of wall, window and door modules, which are preferably attached to the load-bearing construction are releasably attached, whereby the individual modules can be made of wood, plastic, wood composite materials, metal or glass. The box girder profile used for the construction of the load-bearing structure is of crucial importance, both with regard to the mechanical stability, in particular the torsional rigidity, as well as with regard to fire and noise protection requirements, which these room partition systems mainly used in the commercial sector must meet.

Unter Verwendung von Hohlkastenprofilen der eingangs genannten Gattung herstellbare Raumtrennwandsysteme sind beispielsweise aus dem Gebrauchsmuster G 87 17 904 und dem Gebrauchsmuster G 88 16 913 bekannt. Die dort beschriebenen Profilständer besitzen paarweise angeordnete Hohlkammern, deren Seitenwände über einen zentralen Verbindungssteg einstückig miteinander verbunden sind. Die den Wandplatten zugewandten Außenwände der Hohlkammern sind mit Lochstanzungen in Form von Rasteröffnungen versehen, die der Aufnahme von an der Rückseite der Wandplatten befestigten Einhängeorganen dienen oder als Einhängeöffnungen für zusätzliche vorzuhängende Teile wie zum Beispiel Regalkonsolen, Hängeschränke oder dergleichen ausgebildet sind.Room partition wall systems that can be produced using hollow box profiles of the type mentioned at the outset are known, for example, from utility model G 87 17 904 and utility model G 88 16 913. The profile stands described there have hollow chambers arranged in pairs, the side walls of which are integrally connected to one another via a central connecting web. The outer walls of the hollow chambers facing the wall panels are provided with punched holes in the form of grid openings, which serve to accommodate hanging members attached to the rear of the wall panels or are designed as opening openings for additional parts to be curtained, such as shelf consoles, wall cabinets or the like.

Die bekannten Hohlkastenprofile wurden einstückig aus einem Stahlstreifen durch Walzen umgeformt, wobei die beiden Endabschnitte des Bandstahls flächig mit benachbarten Wandabschnitten des Profils durch Schweißen oder Durchsetzfügen ("Verclinchen") verbunden worden sind.The known hollow box profiles were formed in one piece from a steel strip by rolling, the two end sections of the steel strip being connected flatly to adjacent wall sections of the profile by welding or clinching ("clinching").

Obwohl die bekannten Hohlkastenprofile ausreichend verwindungssteif waren und sehr gute Brand- und Schallschutzeigenschaften hatten, konnten sie in ästhetischer Hinsicht nicht alle Wünsche erfüllen, was sich insbesondere bei Glastrennwänden mit Wandpaneelen aus Glas und mit Ganzglastüren negativ bemerkbar machte. Bei Glastrennwänden soll die tragende Konstruktion möglichst zierlich und schlank sein, um die verglaste Fläche nicht mehr als unbedingt nötig zu verringern und um das optische Erscheinungsbild der Trennwand nicht zu stören. Gleichzeitig muß aber die mechanische Stabilität, insbesondere die Verwindungssteifigkeit, des Hohlkastenprofils eher größer sein als bei den bekannten, verhältnismäßig groben und groß dimensionierten Konstruktionen, weil das Gewicht der Ganzglasmodule in der Regel größer ist als dasjenige zweischaliger Trennwände aus Holzpaneelen oder Faserplatten.Although the well-known box girder profiles were sufficiently torsion-resistant and had very good fire and noise protection properties, they could not meet all of the wishes from an aesthetic point of view, which had a particularly negative effect on glass partitions with wall panels made of glass and with all-glass doors. In the case of glass partitions, the supporting structure should be as delicate and slim as possible in order not to reduce the glazed area more than is absolutely necessary and in order not to disturb the visual appearance of the partition. At the same time, however, the mechanical stability, in particular the torsional stiffness, of the hollow box profile must be rather greater than in the known, relatively coarse and large-sized constructions, because the weight of the all-glass modules is usually greater than that of double-skin partition walls made of wood panels or fiberboard.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Hohlkastenprofil zu schaffen, das besonders für Raumtrennwandsysteme in Modulbauweise geeignet ist, deren Module ganz oder überwiegend aus Glas bestehen, wobei das Hohlkastenprofil gleichermaßen als Pfosten und als Riegel verwendbar sein soll und einerseits eine vergleichsweise zierliche Optik, andererseits aber eine mindestens gleich große, vorzugsweise größere Verwindungssteifigkeit als die bisher bekannten gröberen Profile aufweisen soll.The invention is therefore based on the object of creating a box girder profile which is particularly suitable for modular modular partition systems whose modules consist entirely or predominantly of glass, the box girder profile being intended to be used equally as a post and a transom and, on the one hand, a comparatively delicate appearance, on the other hand, it should have at least the same, preferably greater torsional stiffness than the previously known coarser profiles.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Längskanten des im wesentlichen quaderförmig umgeformten, mit Lochstanzungen versehenen Bandstahls, aus dem das Hohlkastenprofil besteht, auf Stoß, ohne Überlappung, miteinander verbunden sind und daß die Kanten des Hohlkastenprofils gerundet und versteift sind.This object is achieved in that the longitudinal edges of the substantially cuboid formed, punched band steel, from which the hollow box section is made, butt-jointed, without overlap, and that the edges of the box section are rounded and stiffened.

Durch die Verbindung der Längskanten des Bandstahls auf Stoß ergibt sich vorzugsweise eine quaderförmige Hohlkastenform, die die bisherige paarweise Anordnung von Hohlkammern und den bisher erforderlichen Verbindungssteg zwischen diesen Kammern, der in bezug auf die Verwindungssteifigkeit des Gesamtprofils eine Schwachstelle war, überflüssig macht. Dadurch kann das erfindungsgemäße Profil nicht nur einfacher, sondern vor allem auch schlanker, zierlicher und mit kleineren Dimensionen hergestellt werden, als dies bisher der Fall war. Die optisch in Erscheinung tretenden Schmalseiten des Hohlkastenprofils brauchen nur noch etwa halb so breit zu sein wie die Halteschenkel oder Halteschenkelpaare der bekannten Profilständer. Außerdem läßt sich das erfindungsgemäße Hohlkastenprofil sowohl als Ständer bzw. Pfosten als auch als Riegel bzw. Deckenanschluß-, Bodenanschluß- oder Wandanschlußprofil verwenden.The connection of the longitudinal edges of the steel strip in a butt joint preferably results in a cuboid box shape, which makes the previous paired arrangement of hollow chambers and the previously required connecting web between these chambers, which was a weak point in terms of the torsional rigidity of the overall profile, superfluous. As a result, the profile according to the invention can not only be manufactured more simply, but above all also more slenderly, more delicately and with smaller dimensions than was previously the case. The narrow sides of the hollow box profile, which appear optically, need only be about half as wide as the holding legs or pairs of holding legs of the known profile stands. In addition, the box girder profile according to the invention can be used both as a stand or post as well as a transom or ceiling connection, floor connection or wall connection profile.

Die Rundung und Versteifung der Kanten des erfindungsgemäßen Hohlkastenprofils verbessert zusätzlich die mechanische Festigkeit, insbesondere die Verwindungssteifigkeit.The rounding and stiffening of the edges of the hollow box profile according to the invention additionally improves the mechanical strength, in particular the torsional rigidity.

Vorzugsweise sind die Kanten des Profils durch Hohlprägen oder Sicken gerundet und versteift.The edges of the profile are preferably rounded and stiffened by hollow embossing or beads.

Bei einer bevorzugten Ausführungsform der Erfindung weisen mindestens die Breitseiten des Profils zusätzliche, nach außen gewölbte Sicken auf, die parallel zu den gerundeten und versteiften Kanten verlaufen und gemeinsam mit den Kanten in Längsrichtung verlaufende Versteifungsrippen bilden, die gleichzeitig als Führungsleisten für aufsteckbare Befestigungsorgane dienen können.In a preferred embodiment of the invention, at least the broad sides of the profile have additional, outwardly curved beads which run parallel to the rounded and stiffened edges and together with the edges form longitudinal stiffening ribs which can simultaneously serve as guide strips for attachable fastening elements.

Vorzugsweise weisen die Breitseiten des Profils je einen nach innen abgekröpften Wandbereich auf, wodurch eine in Längsrichtung verlaufende breite Nut entsteht, die wiederum Befestigungsorgane aufnehmen kann, wie zum Beispiel Glashalter oder Verbindungswinkel für die Verbindung von Pfosten und Riegeln, ohne insgesamt die schlanke Optik des Hohlkastenprofils zu beeinträchtigen.Preferably, the broad sides of the profile each have an inwardly angled wall area, which creates a longitudinal groove that can accommodate fastening elements, such as glass holders or connecting brackets for connecting posts and transoms, without the overall slim appearance of the box girder profile to affect.

Die Längskanten des Bandstahls sind vorzugsweise auf Stoß miteinander verschweißt oder verlötet.The longitudinal edges of the steel strip are preferably butt welded or soldered together.

Bei einer weiteren bevorzugten Ausführungsform der Erfindung sind Lochstanzungen sowohl in den Breitseiten als auch in den Schmalseiten des Profils vorgesehen, die jeweils in einem vorgegebenen Abstand als Rasteröffnungen ausgebildet sind. Diese Rasteröffnungen können als Einhängeöffnungen zum Einhängen geeigneter Einhängeorgane wie zum Beispiel von Winkeln, Haken oder dergleichen, oder als Montageöffnungen für Schrauben, Nieten, Klammern, Bolzen oder dergleichen oder zum Durchführen elektrischer Leitungen, Computerkabeln, Telefonleitungen usw. verwendet werden.In a further preferred embodiment of the invention, punched holes are provided both in the broad sides and in the narrow sides of the profile, which are each designed as grid openings at a predetermined distance. These grid openings can be used as hook-in openings for hooking in suitable hook-in elements such as, for example, angles, hooks or the like, or as mounting holes for screws, rivets, clamps, bolts or the like or for passing through electrical lines, computer cables, telephone lines, etc.

Die Rasteröffnungen in den beiden Breitseiten liegen einander vorzugsweise deckungsgleich gegenüber, um die Durchführung von Leitungen oder Kabeln zu erleichtern. Auch die Rasteröffnungen in den beiden Schmalseiten können einander deckungsgleich gegenüberliegen. Bevorzugt wird jedoch, daß die Rasteröffnungen in den beiden Schmalseiten zwar auf jeder Seite untereinander denselben Rastabstand besitzen, aber bezüglich der Öffnungen auf der jeweils gegenüberliegenden Seite um den halben Rastabstand gegeneinander versetzt sind. Diese versetzte Anordnung der Rasteröffnungen in den beiden Schmalseiten hat den Vorteil, daß von der einen Seite in die Lochstanzungen hineinragende Einhängeorgane oder Befestigungsmittel mit den von der gegenüberliegenden Schmalseite in das Innere des Hohlkastenprofils ragenden Befestigungsorganen nicht in Berührung kommen und daß die Montage auf der einen Seite nicht durch die Montage auf der gegenüberliegenden Seite gestört wird.The grid openings in the two broad sides preferably lie congruently opposite one another in order to facilitate the passage of lines or cables. The grid openings in the two narrow sides can also be congruent. It is preferred, however, that the grid openings in the two narrow sides have the same catch spacing on each side, but are offset by half the catch spacing with respect to the openings on the opposite side. This staggered arrangement of the grid openings in the two narrow sides has the advantage that hanging elements or fasteners projecting into the punched holes from one side do not come into contact with the fastening elements protruding from the opposite narrow side into the interior of the hollow box profile, and that assembly on one side is not disturbed by the assembly on the opposite side.

Die in den Schmalseiten befindlichen Lochstanzungen weisen vorzugsweise eine im wesentlichen quadratische oder rechteckige Form auf. Besonders bevorzugt ist es jedoch, wenn diese Lochstanzungen in den Schmalseiten in mindestens zwei ihrer einander gegenüberliegenden Randbegrenzungen jeweils eine teilkreisförmige Erweiterung zur Führung einer Montageschraube oder eines ähnlichen Verbindungsmittels aufweisen. Besonders vorteilhaft ist eine Ausführungsform, bei der sich der Teilkreis dieser teilkreisförmigen Erweiterungen über mehr als 180° erstreckt, weil sich dann Schrauben oder ähnliche Verbindungsmittel in die durch die teilkreisförmige Erweiterung gebildete Öffnung einstecken lassen, ohne bei der Montage, vor der eigentlichen Befestigung, wieder herauszufallen.The punched holes in the narrow sides preferably have an essentially square or rectangular shape. However, it is particularly preferred if these punched holes in the narrow sides each have a part-circular extension in at least two of their mutually opposite edge boundaries for guiding an assembly screw or a similar connecting means. An embodiment is particularly advantageous in which the pitch circle of these part-circular extensions extends over more than 180 °, because screws or similar connecting means can then be inserted into the opening formed by the part-circular extension, without assembly, before the actual fastening fall out.

Bei einer anderen vorteilhaften Ausführungsform der Erfindung sind die Schmalseiten und Teile der Breitseiten des Hohlkastenprofils durch ein- oder mehrteilige Verschalungen ganz oder teilweise abgedeckt. Dadurch läßt sich eine in Modulbauweise errichtete Raumtrennwand optisch jedem gewünschten Design anpassen. Die Verschalungen sind vorzugsweise mittels geeigneter Verbindungsmittel wie zum Beispiel Klammern durch die Lochstanzungen hindurch an dem Profil befestigt. Die Verbindungsmittel können Rastnasen oder -zungen oder sonstige hintergreifende Teile aufweisen, die sich beispielsweise mittels einer Sollbruchstelle bei Überschreiten einer vorbestimmten Kraft ohne besonderen Aufwand wieder entfernen oder lösen lassen. Die Verschalungen können aus Holz, Holzverbundwerkstoff, Aluminium oder anderen Metallen oder aus Kunststoff bestehen.In another advantageous embodiment of the invention, the narrow sides and parts of the broad sides of the hollow box profile are completely or partially covered by one- or multi-part cladding. This allows a room partition built in modular design to be optically any desired Customize the design. The formwork is preferably fastened to the profile by means of suitable connecting means, for example clips, through the punched holes. The connecting means can have locking lugs or tongues or other engaging parts which can be removed or released again, for example, by means of a predetermined breaking point when a predetermined force is exceeded without any particular effort. The cladding can be made of wood, wood composite material, aluminum or other metals or of plastic.

Bei einer weiteren Ausführungsform des erfindungsgemäßen Hohlkastenprofils weisen die Schmalseiten zusätzlich zu den bereits erwähnten Lochstanzungen Rasteröffnungen auf, die als Einhängeöffnungen zum Einhängen von Regalkonsolen, Möbelteilen oder dergleichen ausgebildet sind, so daß vor eine damit hergestellte Raumtrennwand weitere Teile vorgehängt werden können.In a further embodiment of the box girder profile according to the invention, the narrow sides have, in addition to the hole punchings already mentioned, grid openings which are designed as hook-in openings for hooking in shelf consoles, furniture parts or the like, so that further parts can be hung in front of a room partition produced therewith.

Bei einer besonders vorteilhaften Ausführungsform der Erfindung ist der Innenraum des Hohlkastenprofils in mehrere voneinander getrennte Kammern unterteilt. Diese Unterteilung führt einerseits zu einer weiteren mechanischen Versteifung des Profils und dichtet andererseits die einzelnen Kammern gegen den Durchtritt von Wärme und Schall ab und verringert im Falle eines Brandes die Feuerausbreitungsgeschwindigkeit von einer Seite der Trennwand zur anderen.In a particularly advantageous embodiment of the invention, the interior of the hollow box section is divided into several separate chambers. This subdivision leads on the one hand to a further mechanical stiffening of the profile and on the other hand seals the individual chambers against the passage of heat and sound and, in the event of a fire, reduces the rate of fire spread from one side of the partition to the other.

Die Unterteilung in mehrere Kammern kann beispielsweise durch mindestens ein in Längsrichtung verlaufendes Schott erfolgen. Vorzugsweise weist das Hohlkastenprofil zwei Schotten auf, die aus Stahlblechstreifen bestehen, die einander gegenüberliegende Sicken stegartig miteinander verbinden. Die Stahlblechstreifen können als getrennte Teile eingezogen und eingeklemmt oder durch Kleben, Verlöten oder Verschweißen befestigt sein oder sie können U-förmig gebogen und unter Spannung in das Profil eingesetzt sein.The division into several chambers can be carried out, for example, by at least one bulkhead running in the longitudinal direction. The hollow box profile preferably has two bulkheads which consist of sheet steel strips which connect opposing beads to one another in a web-like manner. The steel sheet strips can be drawn in and clamped as separate parts or fastened by gluing, soldering or welding, or they can be bent into a U-shape and inserted into the profile under tension.

Die U-förmig gebogenen und unter Spannung in das Profil eingesetzten Stahlblechstreifen werden vorteilhaft so in das Profil eingesetzt, daß ihre freien Schenkel in im Bereich der Kanten und Sicken im Inneren des Profils gebildete Stempelrinnen eingreifen.The steel sheet strips bent into a U-shape and inserted under tension into the profile are advantageously inserted into the profile in such a way that their free legs engage in stamp grooves formed in the region of the edges and beads in the interior of the profile.

Die Unterteilung in mehrere Kammern erfolgt bei anderen bevorzugten Ausführungsformen der Erfindung durch mindestens eine in Längsrichtung verlaufende Zwischenwand, die ein- oder mehrlagig durch Umformung des Bandstahls einstückig mit dem Profil gebildet ist. Hierbei wird die mindestens eine Zwischenwand als integraler Bestandteil des Profils mitgeformt. Wenn die Zwischenwand aus zwei aufeinanderliegenden Lagen des einstückig umgeformten Bandstahls gebildet ist, bleibt die äußere Form eines im wesentlichen geschlossenen Quaders erhalten.In other preferred embodiments of the invention, the division into several chambers is carried out by at least one longitudinally extending intermediate wall which is formed in one or more layers by forming the steel strip in one piece with the profile. Here, the at least one partition is formed as an integral part of the profile. If the intermediate wall is formed from two layers of the strip steel which are formed in one piece, the outer shape of a substantially closed cuboid is retained.

Bei weiteren Ausführungsformen der Erfindung können zwei voneinander getrennnte Kammern aber auch dadurch gebildet sein, daß mindestens eine Breitseite des Hohlkastenprofils eine U-förmige Nut aufweist, deren Boden entweder an der gegenüberliegenden Breitseite oder aber am Boden der gegenüberliegend angebrachten U-förmigen Nut anliegt. In diesem Falle ist die Zwischenwand jeweils einlagig durch Umformung des einstückigen Bandstahls gebildet, wobei eine im Querschnitt symmetrische oder asymmetrische "Hundeknochen"-Struktur entsteht, die im Sinne der Erfindung ebenfalls "im wesentlichen quaderförmig" ist, da sie durch ein- oder beidseitiges Einbringen U-förmiger Nuten in die Breitseiten eines streng quaderförmigen Profils entstanden ist.In further embodiments of the invention, two separate chambers can also be formed in that at least one broad side of the hollow box section has a U-shaped groove, the bottom of which lies either on the opposite broad side or on the bottom of the opposite U-shaped groove. In this case, the intermediate wall is in each case formed in one layer by reshaping the one-piece steel strip, a cross-sectionally symmetrical or asymmetrical “dog bone” structure being created which, in the sense of the invention, is also “essentially cuboid” since it can be introduced on one or both sides U-shaped grooves in the broad sides of a strictly cuboid profile was created.

Eine oder mehrere der durch die Schotten gebildeten Kammern oder U-förmigen Nuten können bei Bedarf mit wärmeisolierendem, schallisolierendem und/oder feuerhemmendem Material ausgefüllt sein, beispielsweise mit Fasermattenstreifen, Gipskartonstreifen, Schaumkunststoff, Blähgraphitstäben und dergleichen. Auch ein Teil des Profilquerschnittes selbst kann mit diesen Materialien ausgefüllt oder durch ein eingeschobenes Hohlprofil ausgefüllt und/oder verstärkt sein.One or more of the chambers or U-shaped grooves formed by the bulkheads can, if required, be filled with heat-insulating, sound-insulating and / or fire-retardant material, for example with fiber mat strips, plasterboard strips, foam plastic, expandable graphite rods and the like. A part of the profile cross-section itself can be filled with these materials or by an inserted one Hollow profile filled and / or reinforced.

Das Hohlkastenprofil 1 (Fig. 1, Fig. 2) ist einstückig aus mit Lochstanzungen 11, 12a, 12b, 13, 14 versehenem Bandstahl hergestellt, der so umgeformt worden ist, daß sich eine im wesentlichen quaderförmige Hohlkastenform ergibt. Die Längskanten des Bandstahls sind auf Stoß, ohne Überlappung, durch Verschweißen miteinander verbunden (Schweißnaht 5, Fig. 4). Das Hohlkastenprofil 1 weist zwei einander gegenüberliegende Breitseiten 2, 2' und zwei einander gegenüberliegende Schmalseiten 3, 3' auf. Die vier Kanten 6 des Hohlkastenprofils 1 sind durch Hohlprägen oder Sicken gerundet und versteift. Die Breitseiten 2, 2' weisen je zwei nach außen gewölbte Sicken 8 auf, die parallel zu den Kanten 6 verlaufen. Außerdem besitzen die Breitseiten 2, 2' je einen nach innen abgekröpften Wandbereich 10. Beim Hohlprägen oder Sicken der Kanten 6 sind im Inneren des Hohlkastenprofils 1 Stempelrinnen 7 gebildet worden, beim Einbringen der Sicken 8 entsprechende Stempelrinnen 9 (Figur 4).The hollow box section 1 (Fig. 1, Fig. 2) is made in one piece from band steel provided with punched holes 11, 12a, 12b, 13, 14, which has been reshaped so that an essentially cuboid hollow box shape results. The long edges of the steel strip are joined together by welding without overlap (weld 5, Fig. 4). The hollow box section 1 has two opposite broad sides 2, 2 'and two opposite narrow sides 3, 3'. The four edges 6 of the hollow box section 1 are rounded and stiffened by hollow embossing or beads. The broad sides 2, 2 'each have two beads 8 which are curved outwards and run parallel to the edges 6. In addition, the broad sides 2, 2 'each have an inwardly angled wall region 10. When hollow embossing or beading of the edges 6, stamp grooves 7 have been formed in the interior of the hollow box profile, corresponding stamp grooves 9 have been formed when the beads 8 are introduced (FIG. 4).

Sämtliche Lochstanzungen 11, 12a, 12b und 13 in den Breitseiten 2, 2' und die Lochstanzungen 14 in den Schmalseiten 3, 3' sind als Rasteröffnungen ausgebildet, wobei die Lochstanzungen 14 in jeder der beiden Schmalseiten 3, 3' untereinander denselben Rastabstand x haben. Die Lochstanzungen 14 der einen Schmalseite 3 sind jedoch gegenüber den Lochstanzungen 14 der anderen Schmalseite 3' um den halben Rastabstand x/2 versetzt angeordnet, während die Rasteröffnungen 11, 12a, 12b und 13 in den beiden Breitseiten 2, 2' einander deckungsgleich gegenüberliegen.All punched holes 11, 12a, 12b and 13 in the broad sides 2, 2 'and the punched holes 14 in the narrow sides 3, 3' are designed as grid openings, the punched holes 14 in each of the two narrow sides 3, 3 'having the same locking distance x from one another . However, the punched holes 14 on one narrow side 3 are offset by half the latching distance x / 2 relative to the punched holes 14 on the other narrow side 3 ', while the grid openings 11, 12a, 12b and 13 in the two broad sides 2, 2' are congruent with one another.

Die im wesentlichen rechteckigen Lochstanzungen 14 in den Schmalseiten 3, 3' weisen in ihren einander gegenüberliegenden Randbegrenzungen 15 jeweils eine teilkreisförmige Erweiterung 16 zur Führung bzw. Aufnahme einer Montageschraube auf. Da sich der Teilkreis dieser teilkreisförmigen Erweiterungen 16 über mehr als 180° erstreckt, kann eine durch die Erweiterung 16 gesteckte Schraube nicht herausfallen, obwohl die Erweiterung 16 zur Lochstanzung 14 hin offen ist. Aufgrund der Versetzung um den halben Rastabstand x/2 befinden sich die Erweiterungen 16 der einen Schmalseite 3 im Register mit den Erweiterungen 16 der gegenüberliegenden Schmalseite 3', so daß Schrauben oder sonstige Befestigungsmittel waagerecht durch das gesamte Hohlkastenprofil 1 durchgesteckt werden können, obwohl die Lochstanzungen 14 selbst nicht einander diametral gegenüberliegen.The essentially rectangular punched holes 14 in the narrow sides 3, 3 'each have a part-circular extension 16 for guiding or receiving an assembly screw in their mutually opposite edge boundaries 15. Since the partial circle of these partial circular extensions 16 extends over more than 180 °, a screw inserted through the extension 16 cannot fall out, although the extension 16 is open towards the punched hole 14. Due to the offset by half the locking distance x / 2, the extensions 16 of one narrow side 3 are in register with the extensions 16 of the opposite narrow side 3 ', so that screws or other fasteners horizontally through the entire box section 1 can be inserted, although the punched holes 14 themselves are not diametrically opposed to each other.

Bei der in Figur 4 dargestellten Ausführungsform ist der Innenraum des Hohlkastenprofils 1 durch zwei in Längsrichtung verlaufende Schotten in drei voneinander getrennte Kammern A, B, C unterteilt. Die Schotten bestehen aus Stahlblechstreifen 35, die vorzugsweise keine Lochstanzungen aufweisen. Die Schotten sind im Inneren des Hohlkastenprofils 1 in die dort bei der Ausbildung der Sicken 8 zurückgebliebenen Stempelrinnen 9, die den Konturen der bei der Herstellung verwendeten Profilwalzen entsprechen, eingeschoben und dort entweder durch Verrastung festgelegt oder einfach verklemmt oder aber verklebt, verschweißt oder verlötet. Auf diese Weise sind die einander gegenüberliegenden Sicken 8 stegartig miteinander verbunden, wobei die gegeneinander abgeschotteten Kammern A, B, C mit wärmeisolierendem, schallisolierendem und/oder feuerhemmendem Material (in der Zeichnung nicht dargestellt) ausgefüllt sein können.In the embodiment shown in FIG. 4, the interior of the hollow box section 1 is divided into three separate chambers A, B, C by two bulkheads running in the longitudinal direction. The bulkheads consist of sheet steel strips 35, which preferably have no punched holes. The bulkheads are inserted inside the hollow box section 1 into the stamp grooves 9 left there during the formation of the beads 8, which correspond to the contours of the profile rolls used in the manufacture, and either fixed there by latching or simply jammed or glued, welded or soldered. In this way, the opposing beads 8 are connected to one another in a web-like manner, and the chambers A, B, C which are sealed off from one another can be filled with heat-insulating, sound-insulating and / or fire-retardant material (not shown in the drawing).

Die Verwendung des erfindungsgemäßen Hohlkastenprofils als Profilständer (Pfosten) in der tragenden Konstruktion einer Glastrennwand wird durch die Figuren 5 und 6 erläutert: die Schmalseiten 3, 3' und Teile der Breitseiten 2, 2' des Hohlkastenprofils 1 (Figur 5) sind durch entsprechend genutete Verschalungen 17, 18 aus Holz, Holzverbundwerkstoff oder Kunststoff abgedeckt. Die Verschalungen 17, 18 sind mit Hilfe von Verbindungsklammern 20 am Hohlkastenprofil 1 befestigt, wobei die Verbindungsklammern 20 einerseits am Grund der Nuten 36 der Verschalungen 17, 18 angeschraubt oder angeheftet und andererseits durch die Lochstanzungen 14 in den Schmalseiten 3, 3' des Profils 1 verrastend hindurchgesteckt sind.The use of the hollow box profile according to the invention as a profile stand (post) in the load-bearing structure of a glass partition is illustrated by FIGS. 5 and 6: the narrow sides 3, 3 'and parts of the broad sides 2, 2' of the hollow box profile 1 (FIG. 5) are grooved accordingly Cladding 17, 18 made of wood, wood composite material or plastic covered. The casings 17, 18 are fastened to the box girder section 1 with the aid of connecting brackets 20, the connecting brackets 20 being screwed or tacked to the bottom of the grooves 36 of the casing 17, 18 and on the other hand through the punched holes 14 in the narrow sides 3, 3 'of the section 1 are inserted through it.

Ein Glashalter 32 in Form einer U-förmig gebogenen Schiene aus Metall oder Kunststoff ist mittels geeignet ausgeformter Haltelaschen (nicht dargestellt) in die Lochstanzungen 12a im abgekröpften Wandbereich 10 einer der beiden Schmalseiten 2, 2' eingehängt, um die Glasscheibe 28 des Glastrennwandelementes zu halten. In den Verschalungen 17, 18 sind Dichtungsnuten 30 vorgesehen, in die dauerelastische Dichtungsprofile 29 eingesetzt sind, welche an der Glasscheibe 28 anliegen.A glass holder 32 in the form of a U-shaped rail made of metal or plastic is inserted into the punched holes 12a in the cranked wall area 10 of one of the two narrow sides by means of suitably shaped holding tabs (not shown) 2, 2 'hooked in order to hold the glass pane 28 of the glass partition element. Sealing grooves 30 are provided in the formwork 17, 18, into which permanently elastic sealing profiles 29 are inserted, which bear against the glass pane 28.

Auf der gegenüberliegenden Breitseite 2 ist im abgekröpften Wandbereich 10 eine Türzarge 21 aus Holz befestigt, die ebenfalls eine Dichtungsnut 31 zur Aufnahme der dauerelastischen Türdichtung 27 aufweist. Eine Holztüre 23 ist über Türbänder 25 in der Verschalung 17 drehbar befestigt.On the opposite broad side 2, a wooden door frame 21 is fastened in the cranked wall area 10, which also has a sealing groove 31 for receiving the permanently elastic door seal 27. A wooden door 23 is rotatably fastened in the casing 17 via door hinges 25.

Bei der in Figur 6 dargestellten Glastrennwand ist die Glasscheibe 28 in (nicht dargestellten) Boden- und Deckenanschlußprofilen gehalten, so daß auf den Glashalter 32 verzichtet werden konnte. Auf der gegenüberliegenden Seite des Hohlkastenprofils 1 ist im abgekröpften Wandbereich 10 eine Türzarge 22 befestigt, in deren Dichtungsnut 31 ein dauerelastisches Dichtungsprofil 27 befestigt ist. Anstelle einer Holztüre ist hier eine Ganzglastüre 24 mit Hilfe der Türbänder 26 an einem Spezialbeschlag 33 befestigt, der wiederum mit geeigneten Befestigungsmitteln am Profil 1 befestigt ist. Während die Seite des Hohlkastenprofils 1, an der die Ganzglastüre 24 angeschlagen ist, mit einer Holzverschalung 17 verkleidet ist, ist die gegenüberliegende Seite des Profils 1 mit einer dreiteiligen Verschalung 19a, 19b, 19c aus Aluminiumprofilen abgedeckt, wobei die mittlere Verschalung 19b mit Hilfe von Einhängeorganen 34 in zusätzliche Lochstanzungen auf der Schmalseite des Profils 1 eingehängt ist und bei Bedarf jederzeit wieder ausgehängt werden kann.In the glass partition shown in FIG. 6, the glass pane 28 is held in floor and ceiling connection profiles (not shown), so that the glass holder 32 could be dispensed with. On the opposite side of the hollow box section 1, a door frame 22 is fastened in the cranked wall area 10, in the sealing groove 31 of which a permanently elastic sealing section 27 is fastened. Instead of a wooden door, an all-glass door 24 is fastened here by means of the door hinges 26 to a special fitting 33, which in turn is fastened to the profile 1 with suitable fastening means. While the side of the hollow box section 1, on which the all-glass door 24 is hinged, is clad with a wooden casing 17, the opposite side of the section 1 is covered with a three-part casing 19a, 19b, 19c made of aluminum profiles, the middle casing 19b using Hanging organs 34 is suspended in additional punched holes on the narrow side of the profile 1 and can be removed at any time if necessary.

Die in den Figuren 7 und 8 dargestellten Ausführungsformen des erfindungsgemäßen Hohlkastenprofils zeichnen sich durch Schotten aus U-förmig gebogenen Stahlblechstreifen 37, 38 aus, die unter Spannung in das Profil 1 eingesetzt sind, und zwar vorteilhafterweise so, daß ihre freien Schenkel 39, 40 in die Stempelrinnen 7, 9 eingreifen, die im Inneren des Profils 1 im Bereich der Kanten 6 und Sicken 8 gebildet sind. Durch Einsetzen eines Stahlblechstreifens 37 (Figur 7) entstehen zwei unterschiedlich große, voneinander getrennte Kammern A und H. Würde man symmetrisch dazu einen zweiten U-förmig gebogenen Stahlblechstreifen in das Profil gemäß Figur 7 einsetzen, was ohne weiteres möglich ist, würden drei voneinander getrennte Kammern entstehen, ähnlich den Kammern A, B, C der Ausführungsform gemäß Figur 4. Bei Einsetzen eines Stahlblechstreifens 38 der in Figur 8 dargestellten Form, wird der Innenraum des Profils 1 in drei Kammern A, B, C unterteilt.The embodiments of the hollow box profile according to the invention shown in Figures 7 and 8 are characterized by bulkheads made of U-shaped steel sheet strips 37, 38, which are inserted into the profile 1 under tension, advantageously so that their free legs 39, 40 in the punch grooves 7, 9 engage, which are formed in the interior of the profile 1 in the region of the edges 6 and beads 8 are. By inserting a sheet steel strip 37 (FIG. 7), two differently sized, separate chambers A and H are formed. If a symmetrical U-shaped sheet steel strip were inserted into the profile according to FIG. 7, which is readily possible, three separate ones would be provided Chambers are created, similar to the chambers A, B, C of the embodiment according to FIG. 4. When a sheet steel strip 38 of the shape shown in FIG. 8 is inserted, the interior of the profile 1 is divided into three chambers A, B, C.

Bei den Ausführungsformen des erfindungsgemäßen Hohlkastenprofils gemäß den Figuren 9 bis 11 sind zwei oder drei voneinander getrennte Kammern D, G; D, E, F durch eine oder zwei in Längsrichtung verlaufende Zwischenwände 42 gebildet, welche beim Umformen des Bandstahls als integraler Bestandteil des Profils 1 mitgeformt werden. Die Zwischenwände 42 sind jeweils zweilagig, entstanden durch Zurückbiegen des Bandstahls um 180°, entweder ausgehend von einer Breitseite (Figur 10) oder aber ausgehend von beiden, einander gegenüberliegenden Breitseiten (Figur 9). Bei diesen Ausführungsformen bleibt die im wesentlichen geschlossene Quaderform des Hohlkastenprofils erhalten.In the embodiments of the hollow box section according to the invention according to FIGS. 9 to 11, two or three separate chambers D, G; D, E, F are formed by one or two longitudinal walls 42 which are formed as an integral part of the profile 1 when the steel strip is formed. The intermediate walls 42 are each in two layers, formed by bending the steel strip back through 180 °, either starting from one broad side (FIG. 10) or starting from both opposite broad sides (FIG. 9). In these embodiments, the essentially closed cuboid shape of the hollow box profile is retained.

Bei anderen Ausführungsformen wiederum (Figuren 12 und 13) können die Zwischenwände 41, 41' einlagig durch Umformen des einstückigen Bandstahls gebildet sein, wobei zwei voneinander getrennte Kammern D, F durch mindestens eine in eine Breitseite 2, 2' des Profils 1 eingebrachte U-förmige Nut 43, 44 entstehen, deren Boden 45 entweder an der gegenüberliegenden Breitseite 2' (Figur 13) oder aber am Boden 45' der gegenüberliegend angebrachten U-förmigen Nut 44 (Figur 12) anliegt. Auch die Ausführungsformen gemäß den Figuren 12 und 13 werden erfindungsgemäß unter den Begriff "im wesentlichen quaderförmig" subsumiert, weil die einseitig asymmetrisch eingebrachte Nut 43 (Figur 13) und die symmetrisch beidseitig eingebrachten Nuten 44 (Figur 12) aus der streng quaderförmigen Ausführungsform eine "genutete Quaderform" machen. Auch diese Ausführungsformen besitzen eine gegenüber dem Stand der Technik verbesserte Verwindungssteifigkeit, weil beide Blechstreifen, die den jeweiligen Nutgrund bilden, auf Stoß, ohne Überlappung, miteinander verbunden sind, vorzugsweise nahtlos miteinander verschweißt sind, so daß es keinen Abschnitt gibt, in welchem die Verbindung zwischen den beiden voneinander getrennten Kammern D, F nur aus einem einlagigen Blechstreifen bestehen würde.In other embodiments, in turn (FIGS. 12 and 13), the intermediate walls 41, 41 'can be formed in one layer by reshaping the one-piece steel strip, two separate chambers D, F being formed by at least one U-shaped part 2, 2' of the profile 1. Shaped groove 43, 44 arise, the bottom 45 of which rests either on the opposite broad side 2 '(FIG. 13) or on the bottom 45' of the opposite U-shaped groove 44 (FIG. 12). The embodiments according to FIGS. 12 and 13 are also subsumed according to the invention under the term “essentially cuboid”, because the groove 43 (FIG. 13) introduced asymmetrically on one side and the grooves 44 introduced symmetrically on both sides (FIG. 12) from the strictly cuboid embodiment form a " grooved cuboid shape " do. These embodiments also have a torsional stiffness which is improved over the prior art, because the two metal strips which form the respective groove base are connected to one another in a butt joint without overlap, preferably welded seamlessly to one another, so that there is no section in which the connection between the two separate chambers D, F would only consist of a single-layer sheet metal strip.

Figur 14 schließlich zeigt eine Ausführungsform, bei der ein Teil des Querschnitts des Profils 1 mit wärmeisolierendem, schallisolierendem und/oder feuerhemmendem Material 46 ausgefüllt ist. Dadurch können die Schall- und Brandschutzeigenschaften sowie die wärmeisolierenden Eigenschaften des Hohlkastenprofils deutlich verbessert werden. Beispielsweise können so die durch das eingeschobene Material 46 selbst gebildeten, voneinander getrennten Kammern A, C thermisch voneinander getrennt werden. Das Material 46 kann aus geschäumtem oder nichtgeschäumtem Kunststoff, beispielsweise Polystyrol, Polyurethan oder Silikon, aus Fasermattenzuschnitten, zum Beispiel aus Glasfasern, oder auch aus speziellen Brandschutzmaterialien wie zum Beispiel Blähgraphit enthaltenden Fasermatten oder Polymeren bestehen. Auch Streifen von Gipskartonplatten oder andere herkömmliche Hohlprofile können in das Innere des Hohlkastenprofils 1 eingesetzt oder eingeschoben werden.FIG. 14 finally shows an embodiment in which a part of the cross section of the profile 1 is filled with heat-insulating, sound-insulating and / or fire-retardant material 46. This can significantly improve the sound and fire protection properties as well as the heat-insulating properties of the box girder profile. For example, the separated chambers A, C formed by the inserted material 46 can be thermally separated from one another. The material 46 can consist of foamed or non-foamed plastic, for example polystyrene, polyurethane or silicone, from fiber mat blanks, for example from glass fibers, or also from special fire protection materials such as fiber mats or polymers containing expandable graphite. Strips of plasterboard or other conventional hollow profiles can also be inserted or inserted into the interior of the hollow box profile 1.

Die Erfindung ist selbstverständlich nicht auf die gezeichneten Ausführungsbeispiele beschränkt. So können beispielsweise die auf das Hohlkastenprofil beidseitig aufgebrachten Verschalungen außen in beliebiger Weise profiliert sein. Diese Verschalungen können aus Massivholz, aus furnierten mitteldichten Faserplatten (MDF-Platten) oder aus Aluminiumblenden hergestellt sein.The invention is of course not limited to the illustrated exemplary embodiments. For example, the formwork applied to the hollow box profile on both sides can be profiled in any manner on the outside. This formwork can be made of solid wood, veneered medium density fibreboard (MDF) or aluminum panels.

Die Verglasungen der Glastrennwand-Module können als Einfach- oder Mehrfachverglasungen, auch in besonderen Schallschutz- und Brandschutzausführungen, eingesetzt werden.The glazing of the glass partition wall modules can be used as single or multiple glazing, also in special soundproofing and fire protection designs.

Die als Querriegel und als Pfosten verwendeten Hohlkastenprofile können durch Metallwinkel miteinander verbunden werden, wobei die Materialstärke der Metallwinkel besonders vorteilhaft in den breiten Nuten Platz findet, die durch die abgekröpften Wandbereiche in den Breitseiten der Profile gebildet sind.The box girder profiles used as crossbeams and posts can be connected to each other by metal brackets, the material thickness of the metal brackets being particularly advantageously found in the wide grooves formed by the bent-off wall areas in the broad sides of the profiles.

Das Hohlkastenprofil kann so dimensioniert werden, daß die Breitseiten etwa 50 bis 60 mm, die Schmalseiten etwa 18 bis 22 mm lang sind, so daß die sichtbaren Teile der Verschalungen nur etwa 45 bis 55 mm breit sind.The hollow box profile can be dimensioned so that the broad sides are about 50 to 60 mm, the narrow sides are about 18 to 22 mm long, so that the visible parts of the casing are only about 45 to 55 mm wide.

Die Gesamtkonstruktion kann so ausgelegt werden, daß die Bedingungen der Brandschutzklasse F30 erfüllt werden.The overall construction can be designed so that the conditions of fire protection class F30 are met.

Das Hohlkastenprofil ist höhennivellierbar; durch die als Rasteröffnungen ausgebildeten Lochstanzungen lassen sich Querriegel in beliebiger Höhe, entsprechend dem Rastabstand, einsetzen.The box girder profile is height-adjustable; Due to the perforations, which are designed as grid openings, cross bolts can be used at any height, depending on the locking distance.

Im Inneren des Hohlkastenprofils ist die Führung von Kabeln möglich.Cables can be routed inside the hollow box section.

Türbänder können direkt am Stahlkern des Hohlkastenprofils über Befestigungsplatten fixiert werden.Door hinges can be fixed directly to the steel core of the box girder profile using fastening plates.

Das erfindungsgemäße Hohlkastenprofil ist somit universell einsetzbar und gestattet die Realisierung architektonisch und optisch besonders ansprechender, feingliedriger Glastrennwände mit ausgezeichneter mechanischer Stabilität und insbesondere verbesserter Verwindungssteifigkeit, wobei sich das Profil einfacher und günstiger herstellen läßt als die bisher bekanntgewordenen Lösungen.The box girder profile according to the invention is thus universally applicable and allows the realization of architecturally and optically particularly appealing, delicate glass partition walls with excellent mechanical stability and, in particular, improved torsional rigidity, the profile being easier and cheaper to manufacture than the previously known solutions.
