Abstract

The C-profile for dividing walls, planked on both sides, has two profile flanges (2) linked by a profile base (3). Both profile flanges (2) have a number of parallel beadings (7), projecting outwards, for the wall shells (9,10) to lie against them. The profile base (3) can be smooth, or given one or more longitudinal beadings (6) to give a membrane effect and prevent noise transmission.

Description

Die Erfindung betrifft ein C-Profil aus Blech für beidseitig beplankte Trennwände, mit zwei Profilflanschen und einem davon abgewinkelten, die Profilflansche verbindenden Profilboden, wobei die beiden Profilflansche mehrere parallele, längsverlaufende Sicken aufweisen.The invention relates to a C-profile made of sheet metal for both sides paneled partitions, with two profile flanges and one angled from it, connecting the profile flanges Profile floor, the two profile flanges several have parallel, longitudinal beads.

Derartige, im Querschnitt im wesentlichen U-förmige oder C-förmige C-Profile sind in zahlreichen Ausführungsformen bekannt. Sie werden u.a. als Ständerprofile oder Rahmenprofile für beidseitig beplankte Trennwände eingesetzt, wobei die beiden beispielsweise aus Gipskartonplatten bestehenden Wandschalen an den Profilflanschen angeschraubt sind. Der Zwischenraum zwischen den beiden Wandschalen kann mit Isoliermaterial ausgefüllt sein, um die Luftschallübertragung zwischen den beiden Wandschalen weitgehend zu unterbinden. Die Schallisolationswirkung solcher Trennwände wird daher im wesentlichen durch die Körperschallübertragung durch die C-Profile begrenzt.Such, in cross-section essentially U-shaped or C-shaped C-profiles come in numerous designs known. Among other things, you will as stand profiles or frame profiles used for partition walls clad on both sides, whereby the two, for example made of plasterboard Wall shells are screwed to the profile flanges. The Gap between the two wall shells can with Insulating material must be filled in order to transmit airborne sound largely to prevent between the two wall shells. The sound insulation effect of such partitions is therefore in essentially through the structure-borne noise transmission through the C-profiles limited.

Zur Verminderung der Körperschallübertragung im Bereich der Trennwandständer ist es deshalb bekannt, die Trennwandständer zweiteilig auszuführen. Zwei verhältnismäßig schmale C-Profile sind jeweils nur mit einer der beiden Wandschalen verbunden; zwischen den beiden schmalen C-Profilen befindet sich eine Isolierschicht. Der Herstellungsaufwand für solche zweiteiligen Ständerprofile ist verhältnismäßig hoch.To reduce structure-borne noise transmission in the area of Partition stand it is therefore known, the partition stand to be carried out in two parts. Two relatively narrow C profiles are only with one of the two wall shells connected; between the two narrow C-profiles an insulating layer. The manufacturing effort for such two-piece stand profiles is relatively high.

Es ist auch bekannt, C-Profile mit längsverlaufenden Sicken auch im Profilboden auszuführen. Dadurch werden die Eigenschaften hinsichtlich der Körperschallübertragung aber praktisch nicht beeinflusst.It is also known to have C-profiles with longitudinal beads to be carried out in the profile floor. This will make the Properties with regard to structure-borne noise transmission, however practically not affected.

Bei einem bekannten CD-Profil aus Blech (DE 34 42 355 C1, Fig. 3) sind in den beiden vom Profilboden abgewinkelten Profilflanschen längsverlaufende Sicken vorgesehen, die zum Inneren des C-Profils vorspringen. Wenn an einem solchen CD-Profil eine Beplankung seitlich angebracht wird, so liegt die Beplankung im wesentlichen flächig an der Außenseite der Profilflansche an, so daß eine ungehinderte Körperschallübertragung erfolgen kann. C-Profile mit jeweils nach innen vorspringenden, längsverlaufenden Sicken in den Profilflanschen und im Profilboden sind in unterschiedlichen Ausführungsformen bekannt (DE 44 46 227 A1, DE 43 22 631 C2).In a known CD profile made of sheet metal (DE 34 42 355 C1, Fig. 3) are angled in the two from the profile floor Profile flanges longitudinal beads provided for Project inside the C-profile. If on such a CD profile a planking is attached to the side, so the Planking essentially flat on the outside of the Profile flanges on, so that an unimpeded structure-borne noise transmission can be done. C-profiles with each inside projecting, longitudinal beads in the profile flanges and in the profile floor are in different embodiments known (DE 44 46 227 A1, DE 43 22 631 C2).

Bei einer bekannten Montageschiene (DE 196 12 275 A1, Fig. 6) sind in den Seitenwänden längsverlaufende, hinterschnittene Montagenuten vorgesehen. Solche Montageschienen sind nicht dazu vorgesehen und bestimmt, beidseitig eine Beplankung aufzunehmen.In a known mounting rail (DE 196 12 275 A1, Fig. 6) are longitudinal, undercut in the side walls Installation grooves provided. Such mounting rails are not provided and determined for this purpose, planking on both sides to record.

Aufgabe der Erfindung ist es daher, ein C-Profil der eingangs genannten Gattung so auszubilden, daß mit verhältnismäßig geringem Mehraufwand bei der Herstellung und insbesondere nur verhältnismäßig geringem Mehraufwand an Material eine wesentliche Verringerung der Schallübertragung über das C-Profil erreicht wird. The object of the invention is therefore a C-profile of the beginning mentioned genus so that with a relative little additional effort in the production and in particular only relatively little additional material substantial reduction in sound transmission through the C profile is reached.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die längsverlaufenden Sicken der Profilflansche nach außen vorspringen. Dadurch wird der Oberflächenkontakt der Profilflansche mit den aufliegenden Wandschalen um bis zu 80 - 95% vermindert, und dadurch die Körperschalleinleitung aus den Wandschalen in das C-Profil wesentlich herabgesetzt.This object is achieved in that the longitudinal beads of the profile flanges to the outside project. This will make the surface contact Profile flanges with the overlying wall shells by up to 80 - 95% reduced, and thereby the structure-borne noise significantly reduced from the wall shells into the C-profile.

Gemäß einer Ausgestaltung des Erfindungsgedankens ist vorgesehen, daß der Profilboden mindestens eine Längssicke aufweist, die als verformbare Membran wirkt. Diese Längssicke kann außermittig zu einem der beiden Profilflansche hin versetzt sein. Dadurch verbleibt im Profilboden ausreichend Platz für Einstanzungen oder Durchbrechungen, beispielsweise für Kabeldurchführungen. Der Profilboden kann mehrere Längssicken aufweisen, die gemeinsam als verformbare Membran wirken.According to an embodiment of the inventive concept provided that the profile floor at least one longitudinal bead has, which acts as a deformable membrane. This longitudinal bead can go off-center to one of the two profile flanges be offset. This leaves enough in the profile floor Space for punching or perforations, for example for cable entries. The profile floor can have several Longitudinal beads, which together as a deformable membrane Act.

Die durch die Längssicken erzielte Membranwirkung führt dazu, daß der eingeleitete Schall ein Vibrieren der membranartigen Längssicken verursacht, wodurch es zu einem Energieabbau kommt. Die Schallenergie wird dadurch auf ihrem Weg über den Profilboden durch die Membranwirkung der schwingenden Längssicken zu einem wesentlichen Teil oder sogar vollständig vernichtet und dadurch eine Schallübertragung unterbunden oder doch wesentlich reduziert.The membrane effect achieved by the longitudinal beads leads to that the sound introduced is a vibration of the membrane-like Longitudinal beads caused, which leads to energy loss is coming. The sound energy is thereby on its way over the Profile floor due to the membrane effect of the vibrating Longitudinal beads to a large extent or even completely destroyed, thereby preventing sound transmission or significantly reduced.

Bei mehreren Längssicken ist der Profilboden nach Art eines Faltenbalgs mit längsverlaufenden Falten gestaltet. Dadurch wird zusätzlich der Übertragungsweg für den Körperschall gegenüber einer flachen oder nur mit verhältnismäßig niedrigen Längssicken versehenen Profilbodenwand wesentlich erhöht, so daß zusätzlich die Körperschallübertragung erheblich vermindert wird. Hierzu trägt auch die Tatsache bei, daß wegen der im Winkel zueinander verlaufenden Profilwandstreifen die Laufrichtung des Körperschalls mehrfach umgelenkt wird, was ebenfalls zu einer Verminderung der Körperschallübertragung führt.If there are several longitudinal beads, the profile floor is like one Bellows designed with longitudinal folds. Thereby is also the transmission path for structure-borne noise compared to a flat or only with proportionate low longitudinal beads provided profile floor wall essential increased so that in addition the structure-borne noise transmission is significantly reduced. The fact also contributes to this at that because of the angle to each other Profile wall strips the direction of the structure-borne noise is deflected several times, which also leads to a reduction the structure-borne sound transmission.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand weiterer Unteransprüche.Further advantageous refinements of the inventive concept are the subject of further subclaims.

Nachfolgend werden Ausführungsbeispiele der Erfindung näher erläutert, die in der Zeichnung dargestellt sind.Exemplary embodiments of the invention are described in more detail below explained, which are shown in the drawing.

  • Fig. 2 is a partial section through a partition paneled on both sides with a partition stand made of the C-profile shown in Fig. 1 and
  • 3 - 10 each in section and in spatial representation modified embodiments of C-profile rails.

    • Das in Fig. 1 und 2 dargestellte, aus Blech bestehende C-Profil 1 weist zwei parallele, im Abstand zueinander angeordnete Profilflansche 2 und einen dazu abgewinkelten, die beiden Profilflansche 2 verbindenden Profilboden 3 auf.The one shown in Figs. 1 and 2, consisting of sheet metal C-profile 1 has two parallel, spaced from each other arranged profile flanges 2 and an angled, the profile floor 3 connecting the two profile flanges 2.

    Der Profilboden 3 besteht überwiegend aus längsverlaufenden Profilwandstreifen 4, die jeweils im Querschnitt im Winkel zur Profilbodenebene 5 gerichtet sind, die in Fig. 1 mit strichpunktierten Linien angedeutet ist. Der Profilboden 3 ist im Querschnitt angenähert zickzackförmig nach Art eines Faltenbalgs mit in Profillängsrichtung verlaufenden Falten gestaltet. Jeweils zwei benachbarte, im Winkel zueinander angeordnete Profilwandstreifen 4 bilden eine im Querschnitt V-förmige Längssicke 6, die in das Innere des C-Profils 1 vorspringt. Der Profilboden 3 weist mehrere Längssicken 6 auf, die gemeinsam als verformbare Membran wirken.The profile floor 3 consists predominantly of longitudinal ones Profile wall strips 4, each in cross section at an angle are directed to the profile floor level 5, which in Fig. 1 with dash-dotted lines is indicated. The profile floor 3 is approximately zigzag in cross section like a Bellows with folds running in the longitudinal direction of the profile designed. Two adjacent ones at an angle to each other arranged profile wall strips 4 form a cross section V-shaped longitudinal bead 6, which in the interior of the C-profile 1 protrudes. The profile floor 3 has a plurality of longitudinal beads 6 that work together as a deformable membrane.

    Aus den beiden Profilflanschen 2 springen mehrere parallele längsverlaufende Sicken 7 nach außen vor. Eine der aus dem Profilflansch nach außen vorspringenden längsverlaufenden Sicken 7 liegt im Abstand zur Verbindungskante 8 zwischen dem Profilboden 3 und dem anschließenden Profilflansch 2. Alle Sicken 7 des Profilflanschs 2 laufen über die Flanschlänge ununterbrochen durch.Several parallel jump out of the two profile flanges 2 longitudinal beads 7 outwards. One of the Profile flange protruding outwards Beading 7 is at a distance from the connecting edge 8 between the Profile floor 3 and the subsequent profile flange 2. All Beads 7 of the profile flange 2 run over the flange lengths continuously through.

    Das beschriebene C-Profil bildet ein Rahmenprofil oder Ständerprofil der in Fig. 2 im Querschnitt gezeigten Trennwand, die zwei Wandschalen 9, 10 aufweist. Im Zwischenraum zwischen den beiden Wandschalen 9, 10 sind Isoliermatten 11 eingelegt.The described C-profile forms a frame profile or Stator profile shown in cross section in FIG. 2 Partition wall, which has two wall shells 9, 10. In the gap there are insulating mats between the two wall shells 9, 10 11 inserted.

    Die eine Wandschale 9 ist mittels Schnellbauschrauben 12 an dem einen Profilflansch 2 angeschraubt. Die andere Wandschale 10 ist ebenfalls mittels Schnellbauschrauben 12 an dem anderen Profilflansch 2 angeschraubt. Die beiden Wandschalen 9, 10 liegen dabei jeweils mit ihrer Innenseite 9a bzw. 10a von außen an den Sicken 7 an. Die den Profilboden 3 begrenzenden Verbindungskanten 8 liegen somit im Abstand zur benachbarten Innenfläche 9a bzw. 10a der anschließenden Wandschale 9 bzw. 10. Der von einer der beiden Wandschalen 9 bzw. 10 auf das C-Profil 1 übertragene Schalldruck wirkt sich somit nicht unmittelbar in Richtung des Profilbodens 3 aus, sondern wird nur durch eine Biegebeanspruchung des zwischen der Verbindungskante 8 und der benachbarten Sicke 7 liegenden, wandparallelen Blechstreifens 12 übertragen. Bereits dadurch erfolgt eine Verringerung der Körperschalleinleitung in den Profilboden 3.One wall shell 9 is attached by means of drywall screws 12 screwed to a profile flange 2. The other wall bowl 10 is also by means of drywall screws 12 on the screwed another profile flange 2. The two wall bowls 9, 10 each lie with their inside 9a or 10a from the outside on the beads 7. The profile floor 3 delimiting connecting edges 8 are thus at a distance from adjacent inner surface 9a or 10a of the adjoining Wall shell 9 or 10. The one of the two wall shells 9 or 10 sound pressure transmitted to the C-profile 1 has an effect thus not directly in the direction of the profile floor 3, but is only caused by a bending stress between the the connecting edge 8 and the adjacent bead 7 lying, wall-parallel sheet metal strip 12 transferred. This alone reduces the emission of structure-borne noise in the profile floor 3.

    Die Längssicken 6 im Profilboden 3 wirken gemeinsam als verformbare Membran. Bei der Schalleinleitung führt das Vibrieren der Längssicken 6 zu einem Energieabbau im Bereich des Profilbodens 3.The longitudinal beads 6 in the profile floor 3 act together as deformable membrane. This leads to the introduction of sound Vibrating the longitudinal beads 6 to reduce energy in the area of the profile floor 3.

    Fig. 3 zeigt eine Ausführungsform eines C-Profils, bei dem der Profilboden 3 eben und ununterbrochen ausgeführt ist. Alle Sicken 7 der Profilflansche 2 laufen über die Flanschlänge ununterbrochen durch.Fig. 3 shows an embodiment of a C-profile, in which the profile floor 3 is flat and continuous. All beads 7 of the profile flanges 2 run over the flange lengths continuously through.

    Abweichend hiervon ist beim Ausführungsbeispiel nach Fig. 4 im Profilboden 3 eine einzige, außermittig zu einem der beiden Profilflansche 2 hin versetzte Längssicke 6 vorgesehen. Dadurch verbleibt im Profilboden ausreichend Platz für Einstanzungen oder Durchbrechungen, beispielsweise für für eine H-Einstanzung 3a, aus der durch Umbiegen einer Lasche eine Öffnung im Profilboden 3 für eine Kabeldurchführung geschaffen werden kann.The embodiment of FIG. 4 differs from this in the profile floor 3 a single, off-center to one of the two flanges 2 offset longitudinal bead 6 provided. This leaves enough space for Punches or perforations, for example for an H-punching 3a, from which by bending a tab an opening in the profile floor 3 for a cable entry can be created.

    Beim Beispiel nach Fig. 5 ist der Profilboden 3 ebenso wie beim Beispiel nach Fig. 3 eben ausgeführt; er weist jedoch zwei gegeneinander versetzte Längsreihen von Schlitzen 13 auf. Diese gegeneinander versetzten Schlitze 13 dienen zur Verringerung der Schallübertragung im Profilboden 3. In the example according to FIG. 5, the profile floor 3 is the same as in the example of Figure 3 just executed. however, he points two mutually offset longitudinal rows of slots 13 on. These mutually offset slots 13 are used for Reduction of sound transmission in the profile floor 3.

    Beim Beispiel nach Fig. 6 ist jeder der beiden gemeinsam die Längssicke 6 im Profilboden 3 bildenden Profilwandstreifen 4 jeweils mit einer Längsreihe von Schlitzen 13 versehen, die gegeneinander versetzt sind.In the example according to FIG. 6, each of the two is common Longitudinal bead 6 in the profile base 3 forming profile wall strips 4 each provided with a longitudinal row of slots 13 which are offset from each other.
