Abstract

The pillar profile, for light construction, is in a C-shape with two parallel legs linked by a common member (11) between them with at least one spring section (20) along its longitudinal line. It is shaped to give a lower lateral spring hardness where it is formed from the plane of the center member (11), to give a movable bond for the legs (13,13'). The spring section (20) is bent from the center member (11) at its center and it is symmetrical to the longitudinal center line. Supporting bodies are placed within the hollow of the profile, especially of rock wool or other insulating materials.

Description

Die Erfindung bezieht sich auf ein als Leichtbauprofil ausgebildetes Ständerprofil mit zwei in Parallellage im Abstand voneinander verlaufenden, durch einen gemeinsamen Profilsteg miteinander verbundenen Profilschenkeln. Insbesondere bezieht sich die Erfindung auf ein C-förmiges Ständerprofil mit sich an den vom Profilsteg entfernten Längskanten der Profilschenkel entlangerstreckenden, nach innen gerichteten Randflanschen.The invention relates to a formed as a lightweight profile Stand profile with two in parallel position at a distance diverging, by a common Profile web interconnected profile legs. In particular The invention relates to a C-shaped stand profile with itself on the longitudinal edges removed from the profile web the profile leg extending, inside directed edge flanges.

Ständerprofile dieser Art, insbesondere C-förmige Ständerprofile, sind allgemein bekannt und finden vornehmlich im Trockenbau Verwendung, etwa beim Aufbau von leichten Trennwänden.Stand profiles of this type, in particular C-shaped stand profiles, are generally known and are mainly found in Drywall use, for example when building light partition walls.

Bei derartigen Trennwänden stehen die Profilstege der Ständerprofile senkrecht zu den Wandebenen und mit den Profilschenkeln sind beidseitig angeordnete Leichtbauplatten verschraubt, bei denen es sich beispielsweise um Gipskartonplatten handeln kann. Als Befestigungsschrauben dienen in aller Regel Schrauben mit selbstschneidenden Gewinden. Um das Eindrehen von Schrauben mit selbstschneidenden Gewinden zu erleichtern, sind die Profilschenkel derartiger Ständerprofile normalerweise außenseitig mit sogenannten Fischhaut-Profilierungen ausgerüstet.In such partition walls, the profile webs of the upright profiles are perpendicular to the wall levels and with the profile legs lightweight panels are screwed on both sides, which are, for example, plasterboard can act. Serve as fastening screws in generally screws with self-tapping threads. Around screwing in screws with self-tapping threads to facilitate, the profile legs of such stand profiles usually on the outside with so-called fish skin profiles equipped.

Trennwände dieser Art, bei denen es sich um Zweischalensysteme handelt, müssen vorgegebenen Forderungen hinsichtlich Schallschutz und gegebenenfalls auch im Hinblick auf Feuerschutz genügen. Insoweit sind schon mehrlagige Beplankungen vorgeschlagen worden. Für den Schallschutz bilden bei derartigen Trennwänden die eingesetzten Ständerprofile den Schwachpunkt.Partitions of this type, which are clamshell systems acts, must meet the specified requirements Sound insulation and possibly also with regard to fire protection are enough. In this respect there are already multi-layer planking been proposed. For soundproofing form such Partitions the used stand profiles Weak point.

Aus der DE 36 19 398 C1 ist bereits ein für den Aufbau von Zweischalensystemen bestimmtes Ständerprofil vorbekannt, bei dem die Profilschenkel jeweils über einen sich in Profillängsrichtung erstreckenden Verbindungsbereich, der als Federabschnitt ausgebildet ist, biegeweich an den Profilsteg angeschlossen sind. Die Verbindungsbereiche stehen dabei nach der von den Profilschenkeln wegweisenden Seite randseitig vom Profilsteg vor und bestehen aus in der Art von Haarnadelfedern ausgebildeten duchlaufenden Materialstreifen. Die federnde Bewegbarkeit der Profilschenkel in den vom unverformten Ständerprofil umschlossenen Profilhohlraum hinein ist durch Anschläge begrenzt.From DE 36 19 398 C1 is already one for the construction of Two-shell systems, certain stand profiles are already known, in which the profile legs each have a lengthwise profile extending connection area, which as Spring section is formed, flexible to the profile web are connected. The connection areas are there to the side pointing away from the profile legs in front of the profile web and consist of Art continuous material strips formed by hairpin feathers. The resilient mobility of the profile legs in the profile cavity enclosed by the undeformed stand profile inside is limited by stops.

Die vorbekannte Profilgestaltung stützt sich auf die durch Versuche belegte Erkenntnis, daß bei vorgegebener Beplankung einer Trennwand durch Ständerprofile mit geringer transversaler Federsteife eine Reduzierung der Schalldurchlässigkeit erreicht werden kann.The known profile design is based on the Experiments proved that with the given planking a partition wall with stand profiles with low transverse spring stiffness a reduction in sound permeability can be achieved.

Das vorbekannte Ständerprofil hat sich bewährt, ist aber in der Herstellung recht teuer und erscheint auch unter Schallschutzgesichtspunkten noch verbesserungsbedürftig. Demgemäß besteht die der Erfindung zugrundeliegende Zielsetzung in der Schaffung eines einfach herstellbaren Ständerprofils der vorgenannten Zweckbestimmung, das den Aufbau von Trennwänden mit reduzierter Schalldurchlässigkeit ermöglicht.The previously known stand profile has proven itself, but is in the production quite expensive and also appears under Noise protection aspects still need improvement. Accordingly, the objective underlying the invention is in the creation of an easily manufactured stand profile the aforementioned purpose, which is the construction partition walls with reduced sound permeability.

Gelöst ist diese Erfindungsaufgabe dadurch, daß bei dem Ständerprofil nach dem Oberbegriff des Patentanspruchs 1 der Profilsteg wenigstens einen in Profillängsrichtung verlaufenden Federabschnitt geringer transversaler Federhärte aufweist, der aus der vom Profilsteg aufgespannten Ebene herausgeformt ist und quer zur Profillängserstreckung eine biegeweiche Verbindung der Profilschenkel vermittelt.This invention task is solved in that Stand profile according to the preamble of patent claim 1 the profile web at least one extending in the longitudinal direction of the profile Spring section of low transverse spring hardness has, from the level spanned by the profile web is formed and a transverse to the longitudinal profile flexible connection of the profile legs mediated.

Bei dem erfindungsgemäßen Ständerprofil wird die erwünschte Verminderung der transversalen Federhärte dadurch erreicht, daß der Profilsteg von wenigstens einem längslaufenden Federabschnitt unterbrochen ist und somit das Ständerprofil aus zwei nicht starr, sondern über den genannten Federabschnitt miteinander verbundenen Teilen besteht, die in Abhängigkeit von den Federungseigenschaften des Federabschnittes begrenzt gegeneinander bewegbar sind. In the stand profile according to the invention, the desired Reduction in transverse spring hardness achieved that the profile web of at least one longitudinal spring section is interrupted and thus the stand profile of two not rigid, but over the spring section mentioned interconnected parts that are dependent from the suspension properties of the spring section are limited movable against each other.

Unter Verwendung so ausgebildeter Ständerprofile gelingt der Aufbau von biegeweichen Zweischalensystemen, deren Schalldurchlässigkeit gegenüber Zweischalensystemen mit Ständerprofilen nach dem oben beschriebenen Stande der Technik merklich reduziert ist.Successful using stand profiles designed in this way the construction of flexible double shell systems, their Sound permeability compared to clamshell systems with Stand profiles according to the prior art described above Technology is noticeably reduced.

Für die Minderung der Schalldurchlässigkeit ist es belanglos, nach welcher Seite der Federabschnitt aus der vom Profilsteg aufgespannten Ebene herausgeformt ist. Im Interesse eines leichten Anschlusses beispielsweise an Bauwerkswände ist es jedoch von Vorteil, wenn der Federabschnitt in Richtung der vom Profilsteg vorstehenden Profilschenkel in den Profilinnenraum hineingeformt ist.It is irrelevant for the reduction of the sound permeability, to which side the spring section from that of the profile web spanned plane is formed. In interest easy connection, for example to building walls However, it is advantageous if the spring section in the direction the profile leg protruding from the profile web into the Profile interior is molded.

Selbstverständlich kann der Profilsteg auch anstelle eines längslaufenden Federabschnittes mit mehreren parallel zueinander verlaufenden Federabschnitten ausgerüstet sein, die zweckmäßigerweise untereinander gleich ausgebildet sind.Of course, the profile web can also be used instead of one longitudinal spring section with several parallel to each other extending spring sections, which expediently have the same design as one another are.

Wenn nur ein längslaufender Federabschnitt vorgesehen ist, sollte dieser etwa in der Mitte der Breitenerstreckung des Profilstegs angeordnet und vorzugsweise symmetrisch zu einer Mittellinie des Profilstegs ausgebildet sein.If only one longitudinal spring section is provided, should this be approximately in the middle of the latitude of the Profile web arranged and preferably symmetrical to one Center line of the profile web should be formed.

Während bei dem Ständerprofil nach dem oben erläuterten Stande der Technik die Profilschenkei über als geschlossene haarnadelartige Federabschnitte ausgebildete Verbindungsbereiche biegeweich an den Profilsteg angeschlossen sind, handelt es sich bei dem erfindungsgemäßen Ständerprofil darum, daß der Federabschnitt mit voneinander beabstandeten Lochungen, Schlitzungen oder sonstigen Ausnehmungen versehen ist und demgemäß die sich beidseitig des Federabschnittes erstreckenden Teile des Ständerprofils nur über schmale Materialstege miteinander verbunden sind.While in the stand profile according to the above State of the art about the Profilschenkei as closed hairpin-like spring sections formed connection areas are flexibly connected to the profile web, is the stand profile according to the invention that the spring portion with spaced apart Provide perforations, slits or other recesses is and accordingly on both sides of the spring section extending parts of the stand profile only over narrow Material webs are connected to each other.

Als besonders zweckmäßig hat sich erwiesen, wenn die voneinander beabstandeten Ausnehmungen des Federabschnittes als in Profillängsrichtung verlaufende Schlitzungen ausgebildet sind, desgleichen, daß die Schlitzungen des Federabschnittes gegeneinander versetzt angeordnet sind.It has proven to be particularly useful if the one another spaced recesses of the spring section formed as slits running in the longitudinal direction of the profile are, likewise, that the slits of the spring section are mutually offset.

Eine gleichfalls wichtige Weiterbildung sieht vor, daß die Schlitzungen des Federabschnittes jeweils in benachbarten Reihen und innerhalb jeder Reihe jeweils unter Belassung der genannten schmalen Materialstege angeordnet sind, derart, daß sich über die Materialstege zwischen in Längsrichtung aufeinander folgenden Schlitzen seitlich davon angeordnete Schlitze hinweg erstrecken.An equally important further training provides that the Slits of the spring section in each case in adjacent Rows and within each row with each left said narrow material webs are arranged, such that over the webs of material between in the longitudinal direction successive slots laterally arranged therefrom Extend slots.

Zweckmäßigerweise sind, ebenfalls gemäß einer Weiterbildung der Erfindung, die Schlitzungen des Federabschnittes hinsichtlich Länge und Breite untereinander gleich ausgebildet.Are expedient, also according to a further training of the invention, the slits of the spring section with respect The length and width are the same.

Gemäß einer anderen wichtigen Weiterbildung handelt es sich bei den Schlitzungen des Federabschnittes nicht um Ausstanzungen, sondern um Durchprägungen mit nach einer Seite hochgestellten Schlitzrändern, die zweckmäßigerweise in den Profilinnenraum vorstehen.According to another important training the slits in the spring section are not punched out, but about embossing with to one side raised slit edges, which are conveniently in the Project the interior of the profile.

Derartige Durchprägungen sind in einfacher Weise mittels geeigneter Rollwerkzeuge herstellbar.Such embossings are simple suitable rolling tools can be produced.

Naturgemäß führt die erfindungsgemäß verwirklichte Unterbrechung des Profilstegs durch einen in Profillängsrichtung verlaufenden Federabschnitt geringer transversaler Federhärte dazu, daß die vom Profilsteg bei unverformtem Ständerprofil in Parallellage vorstehenden Profilschenkel beim Eindrehen selbstschneidender Schrauben zwecks Anbringung von Leichtbauplatten aufeinander zu durchfedern können, was logischerweise die Beplankung der Ständerprofile erschwert.The interruption realized according to the invention naturally leads of the profile web by one in the longitudinal direction of the profile running spring section of low transverse spring hardness to ensure that the profile web with undeformed stand profile in parallel projecting profile leg at Screw in self-tapping screws for attachment of lightweight panels to bounce each other what logically the planking of the column profiles is difficult.

Um hier Abhilfe zu schaffen, sieht eine abermalige Weiterbildung der Erfindung vor, daß zwischen den Profilschenkeln Stützelemente aufgenommen sind, die Zusammendrückungen der Profilschenkel unterbinden. Bei diesen Stützelementen kann es sich zweckmäßigerweise um im wesentlichen formfeste Isolierstoffkörper handeln, die etwa aus Steinwolle bestehen und im Profilinnenraum aufgenommen sind. Der Einsatz derartiger Isolierstoffkörper aus Steinwolle führt auch zu einem verbesserten Feuerschutz so aufgebauter Trennwände.To remedy this, see a further training the invention that between the profile legs Support elements are added, the compressions of the Prevent the profile leg. With these support elements can it is expediently essentially dimensionally stable insulating material body act, which consist of stone wool and are included in the profile interior. The use of such Stone wool insulating material body also leads to a improved fire protection of partition walls constructed in this way.

Sofern es auf verbesserten Feuerschutz nicht ankommt, können auch Isolierstoffkörper in Form von Ausspritzungen des Profilinnenraums vorgesehen sein. In Betracht kommen beispielsweise Polyurethanschäume. Sofern derartige Stützelemente sich über die genannte Länge der Ständerprofile erstrecken, erfahren diese Profile auch eine aus Gründen der Stabilität durchaus erwünschte Verbesserung der Längssteifigkeit.Unless improved fire protection is important, you can also insulating body in the form of extrusions of the Profile interior can be provided. Consider, for example Polyurethane foams. If such support elements extend over the stated length of the stand profiles, experience these profiles also for the sake of Stability desired improvement in longitudinal rigidity.
