Abstract

© Ein Blechprofilstab (1) weist gegenüberliegende Profil-Flanschflächen (3, 4) auf, die jeweils mit gegenüberliegenden Wandschalen (7, 8) einer zweischaligen Trennwand verbunden sind. Die beiden Profil-Flanschflächen (3, 4) sind miteinander durch eine Profil-Stegfläche (2) verbunden, die mehrere Längsreihen von Durchbrechungen (9) aufweist. Die Durchbrechungen (9) erstrecken sich in Profilstab-Längsrichtung und sind in den benachbarten Längsreihen gegeneinander versetzt. Dadurch entsteht ein Gitter von Materialstegen (10), die schräg zur Profilstab-Längsrichtung verlaufen. Die Profil-Stegfläche (2) ist in der Normalrichtung der Wandschalen (7, 8) elastisch, so daß die Schwingungsübertragung zwischen den Wandschalen (7, 8) gegenüber einer vollflächigen Stegfläche herabgesetzt ist. Außerdem ist die Wärmeübertragung zwischen den beiden Wandschalen (7, 8) wesentlich vermindert, weil der Querschnitt der Materialstege (10) gering ist und weil der von den Materialstegen (10) vorgegebene Weg für die Wärmeleitung verhältnismäßig lang ist.

© A sheet metal profile bar (1) has opposite profile flange surfaces (3, 4), each of which is connected to opposite wall shells (7, 8) of a double-skin partition. The two profile flange surfaces (3, 4) are connected to each other by a profile web surface (2), which has several longitudinal rows of openings (9). The openings (9) extend in the longitudinal direction of the profile bar and are offset from one another in the adjacent longitudinal rows. This creates a grid of material webs (10) which run obliquely to the longitudinal direction of the profile bar. The profile web surface (2) is elastic in the normal direction of the wall shells (7, 8), so that the vibration transmission between the wall shells (7, 8) is reduced compared to a full-surface web surface. In addition, the heat transfer between the two wall shells (7, 8) is significantly reduced because the cross section of the material webs (10) is small and because the path for heat conduction specified by the material webs (10) is relatively long.

Description

Die Erfindung betrifft einen Blechprofilstab für Traggerippe von zweischaligen Trennwänden, mit mindestens zwei jeweils mit gegenüberliegenden Wandschalen der Trennwand verbindbaren Profil-Flanschflächen, die durch eine Profil-Stegfläche miteinander verbunden sind, die in der Normalrichtung der Wandschalen elastisch ausgeführt ist.The invention relates to a sheet metal profile bar for supporting skeletons of double-skin partition walls, with at least two profile flange surfaces which can each be connected to opposite wall shells of the partition wall and which are connected to one another by a profile web surface which is designed to be elastic in the normal direction of the wall shells.

Für die Traggerippe von zweischaligen Trennwänden werden Blechprofilstäbe mit unterschiedlicher Profilgestalt verwendet. Häufig haben diese Blechprofilstäbe ein C-Profil oder ein U-Profil, wobei sich die Stegfläche jeweils zwischen den beiden Wandschalen erstreckt.und diese miteinander verbindet. Die Übertragung von Schwingungen, insbesondere Schallschwingungen, zwischen den beiden Wandschalen erfolgt zum allergrößten Teil durch diese Profil-Stegflächen.Sheet metal profile bars with different profile shapes are used for the support structure of double-skin partitions. Frequently, these sheet metal profile bars have a C-profile or a U-profile, the web surface extending between the two wall shells and connecting them to one another. The transmission of vibrations, in particular sound vibrations, between the two wall shells takes place for the most part through these profile web surfaces.

Um eine gute Schallisolierung der Trennwand zu erreichen, d. h. eine möglichst geringe Übertragung von Schwingungen zwischen den beiden Wandschalen, wurde bei einem bekannten Blechprofilstab der eingangs genannten Gattung (DE-PS 1 122 686) vorgesehen, die Profil-Stegfläche im Querschnitt stumpfwinklig auszuführen, so daß sie in Normalrichtung der Wandschalen wesentlich elastischer ist als eine sich geradlinig zwischen den beiden Wandschalen erstreckende Stegfläche.In order to achieve good sound insulation of the partition, ie the lowest possible transmission of vibrations between the two wall shells, was provided in a known sheet metal profile bar of the type mentioned (DE-PS 1 122 686) to make the profile web surface at an obtuse angle in cross-section, so that it is substantially more elastic in the normal direction of the wall shells than a straight line between the two Web surface extending wall surface.

Die Wärmeübertragung zwischen den beiden Wandschalen ist jedoch bei dieser im Querschnitt stumpfwinkligen Ausführung der Profil-Stegfläche unverändert gegenüber einem herkömmlichen C-Profil oder U-Profil. Zur Wärmedämmung werden zwar in den zwischen den beiden Wandschalen befindlichen Raum üblicherweise Wärmedämmplatten eingelegt. Die durch die Profil-Stegflächen gebildeten Wärmebrücken bzw. Kältebrücken bleiben jedoch bestehen und machen die Dämmwirkung der eingelegten Dämmplatten mindestens teilweise wieder unwirksam.However, the heat transfer between the two wall shells is unchanged compared to a conventional C-profile or U-profile in this design of the profile web surface which is obtuse in cross section. For thermal insulation, thermal insulation boards are usually inserted into the space between the two wall shells. However, the thermal bridges or cold bridges formed by the profile web surfaces remain and make the insulation effect of the inserted insulation panels at least partially ineffective again.

Aufgabe der Erfindung ist es daher, einen Blechprofilstab der eingangs genannten Gattung so auszubilden, daß ohne wesentliche Verringerung seiner Steifigkeit eine wesentliche Verringerung der Wärmeübertragung zwischen den beiden benachbarten Wandschalen unter gleichzeitiger Verbesserung der Schallisolierung erreicht wird.The object of the invention is therefore to design a sheet metal profile rod of the type mentioned in such a way that a substantial reduction in the heat transfer between the two adjacent wall shells is achieved without a significant reduction in its rigidity while at the same time improving the sound insulation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Profil-Stegfläche mehrere Längsreihen von sich im wesentlichen in Profilstab-Längsrichtung erstreckenden, gegeneinander versetzten Durchbrechungen aufweist.This object is achieved in that the profile web surface has a plurality of longitudinal rows of openings which extend essentially in the longitudinal direction of the profile bar and are offset with respect to one another.

Durch diese sich in Längsrichtung des Profilstabs erstreckenden Durchbrechungen wird nicht nur der Querschnitt der die Wärmeleitung bewirkenden Wärmebrücke zwischen den beiden Profil-Flanschflächen erreicht, sondern insbesondere auch eine Vergrößerung der wirksamen Länge der Wärmebrücke auf einen Wert, der das Mehrfache des Abstands der Profil-Flanschflächen beträgt. Beide Faktoren vermindern die Wärmeleitung zwischen den beiden Profil-Flanschflächen in erheblichem Umfang.These openings, which extend in the longitudinal direction of the profile bar, not only make the cross cut of the thermal bridge causing the thermal conduction between the two profile flange surfaces, but in particular also an increase in the effective length of the thermal bridge to a value which is a multiple of the distance between the profile flange faces. Both factors reduce the heat conduction between the two profile flange surfaces to a considerable extent.

Da die die Durchbrechungen begrenzenden Materialstege sich im wesentlichen in Profil-Längsrichtung erstrecken, werden sie bei in Normalrichtung der Wandplatten wirkenden Kräften, also auch durch Schwingungen der Wandplatten, nur auf Biegung beansprucht, so daß die Profil-Stegfläche in dieser Normalrichtung der Wandschalen sehr elastisch ist. Dadurch werden Schallschwingungen nur sehr wenig übertragen. Die Profil-Stegfläche stellt daher weder eine Wärmebrücke noch eine Schallbrücke dar.Since the material webs delimiting the openings essentially extend in the longitudinal direction of the profile, they are only subjected to bending under the forces acting in the normal direction of the wall panels, that is to say also by vibrations of the wall panels, so that the profile web surface is very elastic in this normal direction of the wall panels is. As a result, sound vibrations are transmitted very little. The profile web surface is therefore neither a thermal bridge nor a sound bridge.

Da die Steifigkeit der Profil-Stegfläche im wesentlichen durch die aufzunehmenden Schubbeanspruchungen bestimmt wird, wird diese Steifigkeit gegenüber einer vollflächigen Ausführung nur geringfügig herabgesetzt, da sich die verbleibenden Materialstege überwiegend in Richtung der Schubbeanspruchung erstrecken.Since the stiffness of the profile web surface is essentially determined by the shear stresses to be absorbed, this stiffness is only slightly reduced compared to a full-surface design, since the remaining material webs extend predominantly in the direction of the shear stress.

Als besonders günstig hat sich in dieser Hinsicht eine Ausführungsform der Erfindung erwiesen, bei der die Profil-Stegfläche als Streckmetallfeld ausgeführt ist. In einem solchen Streckmetallfeld sind die Durchbrechungen längliche Rauten, so daß die verbleibenden Materialstege schräg zur Profilstab-Längsrichtung verlaufen. Das aus diesen schrägverlaufenden Materialstegen gebildete Steggitter ist zur Aufnahme von Schubbeanspruchungen besonders geeignet, so daß eine hohe Steifigkeit der Profilstegfläche erhalten bleibt.An embodiment of the invention in which the profile web surface is designed as an expanded metal field has proven to be particularly favorable in this regard. In such an expanded metal field, the perforations are elongated diamonds, so that the remaining webs of material run obliquely to the longitudinal direction of the section bar. The web grating formed from these inclined material webs is for absorbing shear stresses particularly suitable, so that a high rigidity of the profile web surface is maintained.

Die Ausführung der Profilstegfläche als Streckmetallfeld hat den weiteren Vorteil, daß die Durchbrechungen ohne Materialabfall durch Aufreißen hergestellt werden, d. h. durch Einschneiden und Auseinanderziehen der Einschnittränder. Der für die Herstellung der Stegfläche benötigten Blechstreifen ist daher wesentlich schmaler als die daraus gebildete, durchbrochene Profil-Stegfläche.The design of the profile web surface as an expanded metal field has the further advantage that the perforations are made by tearing without waste of material, i. H. by cutting and pulling apart the cut edges. The sheet metal strip required for the production of the web surface is therefore considerably narrower than the openwork profile web surface formed therefrom.

Gemäß einer anderen Ausführungsform des Erfindungsgedankens können die Durchbrechungen der Profil-Stegfläche als Längsschlitze ausgeführt sein,According to another embodiment of the concept of the invention, the openings in the profile web surface can be designed as longitudinal slots,

Die Erfindung wird nachfolgend an Ausführungsbeispielen näher erläutert, die in der Zeichnung dargestellt sind. Es zeigt:

  • Fig. 1 in perspektivischer Darstellungsweise einen Abschnitt eines Blechprofilstabs mit C-förmigem Querschnitt zwischen zwei Wandschalen und
  • Fig. 2 in einer Darstellung entsprechend der Fig. 1 einen Blechprofilstab mit Trapezquerschnitt.
The invention is explained in more detail below using exemplary embodiments which are illustrated in the drawing. It shows:
  • Fig. 1 shows in perspective a section of a sheet metal profile bar with a C-shaped cross section between two wall shells and
  • Fig. 2 in a representation corresponding to FIG. 1, a sheet metal profile bar with a trapezoidal cross section.

Der in Fig. 1 gezeigte Blechprofilstab 1 mit C-Querschnitt weist eine Profil-Stegfläche 2 auf, von deren beiden Längsrändern sich Profil-Flanschflächen 3 und 4 rechtwinklig in derselben Richtung erstrecken. Die freien Ränder der Profil-Flanschflächen sind zu gegeneinander gerichteten Randstreifen 5 bzw. 6 abgewinkelt. Derartige Blechprofilstäbe 1 dienen zum Aufbau von Traggerippen für zweischalige Trennwände, wobei Wandschalen 7, 8 an den beiden Profil-Flanschflächen 3 bzw. 4 angebracht werden.The sheet metal profile bar 1 shown in FIG. 1 with a C cross section has a profile web surface 2, from the two longitudinal edges of which profile flange surfaces 3 and 4 extend at right angles in the same direction. The free edges of the profile flange surfaces are angled to mutually directed edge strips 5 and 6. Such Sheet metal profile bars 1 are used to build support ribs for double-skin partitions, wall shells 7, 8 being attached to the two profile flange surfaces 3 and 4, respectively.

Die Profil-Stegfläche 2 ist als Streckmetallfeld ausgeführt. Mehrere Längsreihen von sich im wesentlichen in Profilstab-Längsrichtung erstreckenden, angenähert rautenförmigen Durchbrechungen 9 sind durch Einschneiden und Aufreißen des Blechs im Bereich der Profil-Stegfläche 2 entstanden.The profile web surface 2 is designed as an expanded metal field. Several longitudinal rows of approximately diamond-shaped openings 9 extending essentially in the longitudinal direction of the profile bar have been created by cutting and tearing the sheet metal in the region of the profile web surface 2.

Die Durchbrechungen 9 benachbarter Längsreihen sind gegeneinander versetzt. Die zwischen den Durchbrechungen 9 stehengebliebenen Stege 10 verlaufen schräg zur Profilstab-Längsrichiung und bilden ein Gitter, das jedoch keine in Normalrichtung der Wandschalen 7, 8 verlaufenden und diese verbindenden Stege aufweist. Die Profil-Stegfläche 2 ist daher in dieser Normalrichtung sehr elastisch, so daß Schwingungen, beispielsweise Schallschwingungen, nur in sehr geringem Maße übertragen werden. Die Wärmeübertragung zwischen den beiden Profil-Flanschflächen 3 und 4 über die Profil-Stegfläche 2 ist dadurch stark vermindert, daß der Weg für die Wärmeübertragung durch den zick-zack-förmigen Verlauf der Stege 10 sehr groß ist. Außerdem ist der Materialquerschnitt der Stege 10 gering.The openings 9 of adjacent longitudinal rows are offset from one another. The webs 10 which have remained between the openings 9 run obliquely to the longitudinal direction of the section bar and form a grid which, however, has no webs running in the normal direction of the wall shells 7, 8 and connecting them. The profile web surface 2 is therefore very elastic in this normal direction, so that vibrations, for example sound vibrations, are only transmitted to a very small extent. The heat transfer between the two flange profile 3 and 4 via the profile web surface 2 is thereby greatly reduced, that the e W g is very large for the heat transfer through the zigzag-shaped course of the webs 10th In addition, the material cross section of the webs 10 is small.

Eine abgewandelte Ausführungsform ist als Blechprofilstab 11 in Fig. 2 dargestellt. Der Blechprofilstab 11 weist zwei gegenüberliegende, in einer gemeinsamen Ebene angeordneten Profil-Flanschflächen 13 als Randstreifen auf, die jeweils über eine schräg dazu verlaufende Profil- Stegfläche 12 mit einer gemeinsamen, in der Mitte des Blechprofilstabs 11 liegenden Profil-Flanschfläche 14 einstückig verbunden sind. Die beiden Profil-Flanschflächen 13 sind mit der einen Wandschale 17 und die andere Profil-Flanschfläche 14 ist mit der anderen Wandschale 18 verbunden.A modified embodiment is shown as a sheet metal profile bar 11 in FIG. 2. The sheet metal profile rod 11 has two opposing profile flange surfaces 13 arranged in a common plane as edge strips, which are each connected in one piece via an inclined profile web surface 12 to a common profile flange surface 14 lying in the middle of the sheet metal profile rod 11. The two profile flange surfaces 13 are connected to one wall shell 17 and the other profile flange surface 14 is connected to the other wall shell 18.

Die Profil-Stegflächen 12 weisen auch hierbei Durchbrechungen 19 auf, die als mehrere Längsreihen von gegeneinander versetzten Längsschlitzen ausgeführt sind. Zwischen den benachbarten Reihen von Längsschlitzen 19 bleiben Materialstege 20 bestehen, die sich in Profilstab-Längsrichtung erstrecken und bei der Übertragung von Kräften in Normalrichtung zu den Wandschalen 17, 18, insbesondere bei der Schwingungsübertragung, als elastische Biegebalken wirken. Ebenso wie beim Ausführungsbeispiel nach Fig. 1 ist auch hierbei der Weg für eine Wärmeübertragung zwischen den Profil-Flanschflächen 13 und 14 verhältnismäßig lang, während der hierfür zur Verfügung stehende Materialquerschnitt gering ist.The profile web surfaces 12 also have openings 19, which are designed as a plurality of longitudinal rows of mutually offset longitudinal slots. Between the adjacent rows of longitudinal slots 19 there remain material webs 20 which extend in the longitudinal direction of the profile bar and act as elastic bending beams when forces are transmitted in the normal direction to the wall shells 17, 18, in particular when transmitting vibrations. As in the embodiment of FIG. 1, the path for heat transfer between the profile flange surfaces 13 and 14 is also relatively long, while the material cross section available for this is small.

Beiden dargestellten Ausführungsbeispielen ist gemeinsam, daß durch die wesentliche Verringerung der Wärmeleitmöglichkeiten die Bildung von Wärmebrücken bzw. Kältebrücken im Bereich der Blechprofilstäbe des Traggerippes einer Trennwand verhindert wird. Zugleich wird dadurch die Brandschutzwirkung verbessert, weil sich die im Brandfall auf einer Seite der Trennwand auftretende hohe Temperatur nicht auf die andere Wandseite überträgt.Both of the exemplary embodiments shown have in common that the formation of thermal bridges or cold bridges in the area of the sheet-metal profile bars of the supporting structure of a partition wall is prevented by the substantial reduction in the heat-conducting possibilities. At the same time, the fire protection effect is improved because the high temperature that occurs in the event of fire on one side of the partition does not transfer to the other side of the wall.

Die beiden dargestellten Profilformen stellen nur zur Erläuterung herausgegriffene Beispiele aus zahlreichen Ausführungsmöglichkeiten dar. Es versteht sich, daß die Ausführung der Profil-Stegfläche als Streckmetallfeld, die in Fig. 1 gezeigt wurde, auch bei einem Profilquerschnitt nach Fig. 2 verwendet werden kann und umgekehrt. Auch sonstige Profilquerschnitte sind möglich, sofern diesen nur gemeinsam ist, daß sie eine die beiden Wandschalen verbindende Profil-Stegfläche aufweisen.The two profile shapes shown are only examples from numerous examples Possible designs. It goes without saying that the design of the profile web surface as an expanded metal field, which was shown in FIG. 1, can also be used with a profile cross section according to FIG. 2 and vice versa. Other profile cross sections are also possible, provided that they only have one thing in common that they have a profile web surface connecting the two wall shells.
