Abstract
Description
Die Erfindung beziehtsich auf ein als Leichtbauprofil ausgebildetes Ständerprofil mit zwei in Parallellage im Abstand voneinander verlaufenden, durch einen gemeinsamen Steg miteinander verbundenen Profilschenkeln, insbesondere auf ein C-förmiges Ständerprofil mit sich an den vom Steg entfernten Längskanten der Profilschenkel entlangerstreckenden, nach innen gerichteten Randflanschen.The invention relates to a stand profile designed as a lightweight construction profile with two profile legs running at a distance from one another in a parallel position and connected to one another by a common web, in particular to a C-shaped stand profile with inwardly directed edge flanges extending along the longitudinal edges of the profile legs remote from the web.
Ständerprofile dieser Art, insbesondere C-förmige Ständerprofile, sind allgemein bekannt und finden vornehmlich im Trockenbau Verwendung, etwa beim Aufbau von leichten Trennwänden.Column profiles of this type, in particular C-shaped column profiles, are generally known and are used primarily in drywall construction, for example when building light partition walls.
Bei derartigen Trennwänden stehen die Stege der Ständerprofile senkrecht zu den Wandebenen und mit den Profilschenkeln sind beidseitig angeordnete Leichtbauplatten verschraubt. 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 sog. Fischhaut-Profilierungen versehen.In partition walls of this type, the webs of the upright profiles are perpendicular to the wall planes, and lightweight construction panels arranged on both sides are screwed to the profile legs. As a rule, screws with self-tapping threads are used as fastening screws. To screw in screws with self-tapping To facilitate threading, the profile legs of such stand profiles are normally provided on the outside with so-called fish skin profiles.
Naturgemäß haben die einzusetzenden Leichtbauplatten nur begrenzte Flächenausdehnungen, so daß beim Aufbau von Trennwänden notwendig Platten unter Ausbildung von Stoßstellen stirnseitig aneinander angrenzend angeordnet werden müssen. Derartige Stoßstellen werden längs eines Profilschenkels in der Weise ausgebildet, daß je ein Randstreifen der benachbarten Leichtbauplatten mit demselben Profilschenkel eines Ständerprofils verschraubt wird. Das Verschrauben des Randstreifens der sich stegseitig vom Ständerprofil forterstreckenden Leichtbauplatte bereitet dabei in aller Regel keine Schwierigkeiten. Hingegen können beim Verschrauben des Randstreifens einer sich nach der anderen Seite von der Stoßstelle forterstreckenden Leichtbauplatte Probleme insofern auftreten, als die Befestigungsschrauben in größeren Abständen von dem die Profilschenkel des Ständerprofils miteinander verbindenden Steg am betreffenden Profilschenkel angreifen und infolge der beim Eindrehen aufzuwendenden Kraft die Profilschenkel in den vom unverformten Ständerprofil umschlossenen Profilhohlraum hinein ausweichen, wobei in den Verbindungsbereichen zwischen den Profilschenkeln und dem Steg die Elastizitätsgrenze des Materials überschritten werden und mithin bleibende Verformungen auftreten können. Dies führt zu einem höchst unerwünschten Versatz zwischen benachbarten Leichtbauplatten, der nur durch zeit- und kostenaufwendiges Auftragen von Spachtelmasse ausgeglichen werden kann.Naturally, the lightweight panels to be used have only limited surface areas, so that when partitions are built, panels must be arranged adjacent to one another on the end face to form butt joints. Such joints are formed along a profile leg in such a way that one edge strip of the adjacent lightweight building boards is screwed to the same profile leg of a stand profile. The screwing of the edge strip of the lightweight board extending from the stator profile on the web side generally does not cause any difficulties. On the other hand, problems can arise when screwing the edge strip of a lightweight building board extending to the other side from the joint, insofar as the fastening screws engage at greater distances from the web connecting the profile legs of the stand profile to the relevant profile leg and, as a result of the force to be applied when screwing in, the profile legs in dodge the profile cavity enclosed by the undeformed stator profile, the elastic limit of the material being exceeded in the connection areas between the profile legs and the web, and permanent deformations can therefore occur. This leads to a highly undesirable offset between adjacent lightweight building boards, which can only be compensated for by time-consuming and costly application of filler.
Um insoweit Abhilfe zu schaffen, ist schon vorgeschlagen worden, die Steifigkeit derartiger Ständerprofile zu erhöhen, etwa durch das Einprägen von Quersicken in die Profilschenkel und Stege, die sich zwischen letzteren übereck erstrecken. Durch diese Maßnahme konnte zwar die Gefahr des "Durchfederns" der Profilschenkel über den elastischen Bereich hinaus reduziert werden, aber bei Trennwänden, die unter Verwendung so versteifter Ständerprofile aufgebaut sind, zeigte sich eine erhöhte Schalldurchlässigkeit.In order to remedy this, it has already been proposed to increase the rigidity of such stand profiles, for example by embossing transverse beads into the profile legs and webs which extend between the latter in a corner. With this measure, the risk of "springing" of the profile legs beyond the elastic range could be reduced, but an increase in sound permeability was shown in the case of partition walls which were constructed using stiffened stand profiles.
Die der Erfindung zugrundeliegende Aufgabe besteht daher in der Verbesserung des eingangs angegebenen Ständerprofils dahingehend, daß dieses einerseits die Anbringung von Leichtbauplatten auch im Bereich von Stoßstellen ohne merklichen Plattenversatz, der kostenaufwendige Ausgleichsarbeiten erfordert, und andererseits den Aufbau von Trennwänden ohne erhöhte Schalldurchlässigkeit ermöglicht.The object on which the invention is based is therefore to improve the stator profile specified at the outset in such a way that on the one hand this enables the attachment of lightweight panels in the area of joints without noticeable panel offset, which requires costly compensation work, and on the other hand enables the construction of partition walls without increased sound permeability.
Gelöst ist diese Erfindungsaufgabe dadurch, daß bei einem Ständerprofil nach dem Oberbegriff des Patentanspruchs 1 die Profilschenkel über als Federabschnitte mit geringer transversaler Federhärte ausgebildete Verbindungsbereiche, die sich in Profillängsrichtung erstrecken, beigeweich an den Steg angeschlossen sind, und daß die federnde Bewegbarkeit der sich von den Federabschnitten forterstreckenden Bereiche der Profilschenkel in den vom unverformten Ständerprofil umschlossenen Profilhohlraum hinein durch Anschläge begrenzt ist.This object of the invention is achieved in that, in the case of a stand profile according to the preamble of claim 1, the profile legs are connected to the web via connecting regions which are designed as spring sections with a low transverse spring hardness and which extend in the longitudinal direction of the profile, and that the resilient mobility of the Areas of the profile legs that extend toward the spring sections are limited by stops in the profile cavity enclosed by the undeformed stator profile.
Der Erfindung liegt die inzwischen durch Versuche bestätigte Erkenntnis zugrunde, daß bei vorgegebener Beplankung einer Trennwand eine Verringerung der Schallübertragung durch Verminderung der transversalen Federsteife des Ständerprofils erreicht werden kann.The invention is based on the knowledge, which has now been confirmed by tests, that with a given planking of a partition, a reduction in sound transmission can be achieved by reducing the transverse spring stiffness of the stator profile.
Bei dem erfindungsgemäßen Ständerprofil wird die im Vergleich zu Ständerprofilen nach dem Stande der Technik durchaus erwünschte Verminderung der transversalen Federhärte dadurch erreicht, daß die Verbindungsbereiche zwischen den Profilschenkeln und dem Steg als Federabschnitte ausgebildet sind. Naturgemäß weichen bei dem so ausgebildeten Ständerprofil die Profilschenkel unter der Wirkung senkrecht zu den Flächenerstreckungen der Profilschenkel angreifender Kräfte, wie sie beim Eindrehen selbstschneidender Schrauben auftreten, leichter aus als die Profilschenkel herkömmlicher Ständerprofile. Diesen Ausweichbewegungen werden aber durch die erfindungsgemäß vorgesehenen Anschläge enge Grenzen gesetzt, indem die Profilschenkel beim Durchfedern in den vom unverformten Ständerprofil umschlossenen Profilhohlraum hinein bereits nach dem Zurücklegen kleiner Federwege, die im elastischen Bereich der Federabschnitte liegen auf diese Anschläge auftreffen. Bei sachgerechter bestimmungsgemäßer Verwendung des erfindungsgemäßen Ständerprofils können somit in den als Federabschnitte ausgebildeten Verbindungsbereichen zwischen den Profilschenkeln und dem Steg keine bleibenden Verformungen auftreten. Nach dem Wegfall der das Durchfedern der Profilschenkel bewirkenden Kräfte federn die Profilschenkel mithin in ihre Ursprungslagen zurück, womit der bei herkömmlichen Ständerprofilen im Bereich von Stoßstellen zu beobachtende Plattenversatz vermieden ist.In the upright profile according to the invention, the reduction in the transverse spring hardness which is quite desirable in comparison to upright profiles according to the prior art is achieved in that the connecting regions between the profile legs and the web are designed as spring sections. Naturally, in the stand profile formed in this way, the profile legs dodge more easily than the profile legs of conventional stand profiles under the action of forces acting perpendicularly to the surface extensions of the profile legs, such as occur when self-tapping screws are screwed in. However, these evasive movements are limited by the stops provided according to the invention, in that the profile legs spring into the profile cavity enclosed by the undeformed stator profile even after covering small spring paths which lie in the elastic region of the spring sections and strike these stops. If the stator profile according to the invention is used correctly and in accordance with the intended purpose, no permanent deformations can thus occur in the connection areas formed as spring sections between the profile legs and the web. After the forces causing the profile limbs to cease to spring, the profile limbs spring back into their original positions, thus avoiding the plate offset that can be observed in the area of butt joints in conventional column profiles.
Eine zweckmäßige Ausgestaltung der Erfindung sieht vor, daß die als Federabschnitte ausgebildeten Verbindungsbereiche zwischen den Profilschenkeln und dem Steg von letzterem nach der von den Profilschenkeln entfernten Seite -im Querschnitt gesehen- haarnadelartig geformte Materialstreifen sind, die in Randstreifen der Profilschenkel übergehen.An expedient embodiment of the invention provides that the connection areas, designed as spring sections, between the profile legs and the web are, from the latter, towards the side removed from the profile legs, as seen in cross section, strips of material shaped like a hairpin, which merge into edge strips of the profile legs.
Bei einem so gestalteten Ständerprofil sind die Profilschenkel besonders "weich" an den Steg angeschlossen und angesichts der dadurch bedingten geringen transversalen Federhärte des Ständer-profils zeichnet sich dieses durch ein im Vergleich zu Ständerprofilen nach dem Stande der Technik besonders hohes Schalldämmaß aus.In the case of a stand profile designed in this way, the profile legs are connected to the web in a particularly "soft" manner and, in view of the resulting low transverse spring hardness of the stand profile, this is characterized by a particularly high sound insulation in comparison to stand profiles according to the prior art.
Die zur Begrenzung des Durchfederns der Profilschenkel in Richtung auf den vom unverformten Ständerprofil umschlossenen Profilhohlraum gemäß der Erfindung vorzusehenden Anschläge, auf welche die Profilschenkel vor dem Überschreiten der Elastizitätsgrenze des Materials in den Verbindungsbereichen auftreffen, können grundsätzlich in beliebiger Form ausgebildet sein. Eine insoweit besonders vorteilhafte Ausgestaltung der Erfindung ist jedoch dadurch gekennzeichnet, daß die äußeren Längskanten des Steges, von denen sich die haarnadelartig nach der von den Profilschenkeln entfernten Seite geformten Federabschnitte forterstrecken, Anschläge bilden, an denen sich die Profilschenkel abstützen, wenn die sich vom Steg forterstreckeneden Bereiche der Profilschenkel im Rahmen der elastischen Federeigenschaften der Federabschnitte um ein vorbestimmtes Maß in den vom ungeformten Ständerprofil umschlossenen Profilhohlraum hineingeformt sind.In order to limit the deflection of the profile legs in the direction of the profile cavity to be provided by the undeformed stator profile according to the invention, which the profile legs hit in the connection areas before the elastic limit of the material is exceeded, they can in principle be designed in any shape. A particularly advantageous embodiment of the invention, however, is characterized in that the outer longitudinal edges of the web, from which the hairpin-like spring sections extend to the side shaped away from the profile legs, form stops on which the profile legs are supported, when they extend from the web forward-stretching areas of the profile legs within the framework of the elastic spring properties of the spring sections by a predetermined amount in the unshaped stator profile enclosed profile cavity are formed.
Es handelt sind mithin bei dieser Ausgestaltung darum, daß der Abstand zwischen den längslaufenden Kanten des Steges, an welche die haarnadelartig ausgebildeten Federabschnitte angeformt sind, und den Profilschenkeln so bemessen ist, daß die Profilschenkel beim Durchfedern in den vom unverformten Ständerprofil umschlossenen Hohlraum hinein, also beispielsweise beim Eindrehen selbstschneidender Schrauben, auf die Längskanten des Steges auftreffen und dadurch an einem weiteren Ausweichen in Richtung des Profilhohlraums gehindert werden. Dadruch ist die Bewegbarkeit der Profilschenkel in Richtung des unverformten Profilhohlraums auf den elastischen Bereich der Federabschnitte beschränkt und sichergestellt, daß die Profilschenkel aus den beim Befestigen von Leichtbauplatten auftretenden Verformungslagen in ihre Ursprungslagen zurückfedern.It is therefore in this embodiment that the distance between the longitudinal edges of the web, to which the hairpin-shaped spring sections are formed, and the profile legs is dimensioned such that the profile legs during deflection into the cavity enclosed by the undeformed stator profile, that is For example, when screwing in self-tapping screws, hit the longitudinal edges of the web and are thereby prevented from evading further in the direction of the profile cavity. This means that the mobility of the profile legs in the direction of the undeformed profile cavity is limited to the elastic region of the spring sections and ensures that the profile legs spring back into their original positions from the deformation positions that occur when fastening lightweight building boards.
Gemäß einer Weiterbildung der zuletzt genannten Ausgestaltung sind in die Profilschenkel quer zu ihrer Längserstreckung verlaufende Versteifungssicken von den Außenseiten in Richtung auf den Profilhohlraum hineingeformt, die sich über die vom Steg aufgespannte Ebene hinaus und bis in die den Anschluß and die Federabschnitte vermittelnden Randstreifen der Profilschenkel hineinerstrecken. Diese Quersicken vermitteln einerseits eine vergleichsweise hohe Flächensteifigkeit der Profilschenkel und andererseits im Zusammenwirken mit den als Anschläge dienenden Längskanten des Steges eine präzise Begrenzung der Federwege der Profilschenkel in Richtung des vom unverformten Ständerprofil umschlossenen Profilhohlraums.According to a further development of the last-mentioned embodiment, stiffening beads extending transversely to their longitudinal extension are formed from the outer sides in the direction of the profile cavity, which extend beyond the plane spanned by the web and into the edge strips of the profile legs which mediate the connection and the spring sections . These transverse beads impart on the one hand a comparatively high surface rigidity of the profile legs and, on the other hand, in cooperation with the longitudinal edges of the web serving as stops, a precise limitation of the spring travel of the profile legs in the direction of the profile cavity enclosed by the undeformed stator profile.
