Description

Die Erfindung bezieht sich auf eine Unterkonstruktion für gewölbte Abhängedecken aus entsprechend geformten Deckenbekleidungsplatten, insbesondere aus der geforderten Deckenwölbung entsprechend gebogenen Gipskartonplatten, mit an einer Baukörperdecke, etwa einer Rohbaudecke, befestigten Tragelementen zum Anbringen der Decken­bekleidungsplatten.The invention relates to a substructure for curved suspended ceilings made of appropriately shaped ceiling cladding panels, in particular from the required ceiling curvature correspondingly bent plasterboard, with supporting elements attached to a structural ceiling, such as a structural ceiling, for attaching the ceiling cladding panels.

Insbesondere im Innenausbau, aber auch im Bereich von Arkaden in Fußgängerzonen, gewinnen gewölbte Abhängedecken zunehmend Bedeutung.Häufig handelt es sich dabei um an entsprechend gestalteten Unterkon­struktionen angebrachte Gipskartonplatten als Decken­verkleidungen, die vor ihrer Anbringung an derartigen Unterkonstruktionen auf speziell angefertigten Schablonen durch Biegen in die gewünschte Form gebracht und damit der geforderten Wölbung einer Unterdecke ange­paßt worden sind.Vaulted ceilings are becoming increasingly important, particularly in interior fittings, but also in the area of arcades in pedestrian zones. Often, these are plasterboard panels attached to appropriately designed substructures as ceiling cladding, which before being attached to such substructures on specially manufactured templates by bending into the desired ones Formed and thus the required curvature of a false ceiling have been adjusted.

Bei gewölbten Abhängedecken herkömmlicher Art werden die der gewünschten Deckenwölbung entsprechend ge­bogenen Deckenverkleidungsplatten an Tragelementen befestigt, die ihrerseits in vorbestimmten Abständen voneinander quer zur Gewölbelängserstreckung aufgehängt bzw. in geeigneter Weise am Verankerungsgrund, bei dem es sich vornehmlich um Baukörperdecken handelt, angebracht und unterseitig dem Konturenverlauf der Deckenwölbung entsprechend gestaltet sind. Als Trag­elemente sind bisher am Verankerungsgrund verdübelte Holzkonstruktionen eingesetzt worden, die sich aller­dings als sehr kostenaufwending erwiesen haben, und zwar insbesondere dann, wenn im Zwischenraum zwischen der abgehängten Unterdecke und der Baukörperdecke zu verlegende Kabel, Leitungen oder sonstigte Installationen zu berücksichtigen und demgemäß die Tragelemente mit entsprechenden "Fensterausnehmungen" zu versehen waren.In the case of arched suspended ceilings of a conventional type, the ceiling cladding panels bent in accordance with the desired ceiling curvature are fastened to supporting elements, which in turn are suspended at predetermined distances from one another transversely to the longitudinal vault extension or in a suitable manner on the anchoring base, which is primarily structural ceilings, attached and on the underside of the contour course of the Ceiling curvature are designed accordingly. So far dowelled wooden constructions have been used as supporting elements, which have proven to be very costly, however, especially if cables, lines or other installations to be laid in the space between the suspended false ceiling and the structural ceiling have to be taken into account and the supporting elements accordingly corresponding "window recesses" had to be provided.

Vor diesem Hintergrund besteht die der Erfindung zugrundeliegende Aufgabe in der Schaffung einer im Aufbau einfacheren, insbesondere kostengünstigeren Unterkonstruktion für den vorgenannten Zweck, die beispielsweise auch das unproblematische Verlegen von Installationen im Zwischenraum zwischen einer abgehängten Unterdecke und einem letztere tragenden Verankerungsgrund zuläßt.Against this background, the object on which the invention is based is to provide a substructure which is simpler in construction, in particular less expensive, for the aforementioned purpose and which, for example, also allows unproblematic laying of installations in the space between a suspended false ceiling and anchoring base supporting the latter.

Gelöst ist diese Erfindungsaufgabe durch den Aufbau der Unterkonstruktion aus quer zur Gewölbelängser­streckung in vorbestimmten Abständen voneinander abgehängten, der Deckenwölbung entsprechend gebogenen Querträgern, und aus unterseitig an den gebogenen Querträgern in vorbestimmten Abständen voneinander in Gewölbelängsrichtung verlaufend befestigten Decken­trageschienen zum unterseitigen Anbringen der Decken­bekleidungsplatten.This task of the invention is solved by the construction of the substructure from transverse beams suspended at predetermined intervals from one another transversely to the longitudinal vault extension, and from the underside on the curved crossbeams which are curved in accordance with the ceiling curvature Cross beams at predetermined intervals from each other in the vault longitudinal direction attached ceiling support rails for attaching the ceiling cladding panels.

Bei der Erfindung handelt es sich somit darum, daß abweichend vom Stande der Technik als Unterkonstruktion ein Traggerüst aus Querträgern, die der geforderten Wölbung entsprechend gebogen und an der Baukörper­decke abgehängt sind, und an diesen Querträgern unter­seitig befestigten Längsträgern in Form von Decken­trageschienen, an denen die Deckenbekleidungsplatten zu befestigen sind, geschaffen worden ist. Eine derartige Unterkonstruktion ist einerseits einfach herstellbar und daher kostengünstig, andererseits aber auch im Hinblick auf die Nutzung des Zwischenraums über der abgehängten Unterdecke vorteilhaft, weil für diese Abhängung lediglich platzsparende und bei abgehängten Unterdecken bekannte Hängedrähte oder jedenfalls nur solche Befestigungsmittel erforderlich sind, die den Zwischenraum zwischen der Unterkonstruktion und dem Verankerungsgrund nicht wesentlich verbauen.The invention is therefore that, in contrast to the prior art as a substructure, a support structure made of cross members, which are bent according to the required curvature and are suspended from the structural ceiling, and on these cross members underside fixed longitudinal beams in the form of ceiling support rails on which the Ceiling cladding panels are to be attached, has been created. Such a substructure is easy to manufacture and therefore inexpensive, but also advantageous with regard to the use of the space above the suspended ceiling, because for this suspension only space-saving hanging wires known for suspended ceilings or in any case only those fasteners are required that cover the space not significantly obstruct between the substructure and the anchoring base.

Vorteilhafte Ausgestaltungen der Erfindung sind in den nachgeordneten Patentansprüchen angegeben.Advantageous embodiments of the invention are specified in the subordinate claims.

So sieht die Ausgestaltung gemäß Patentanspruch 2 vor, daß die Querträger aus zwei übereinanderliegenden und schubfest miteinander verbindbaren Bändern bestehen. Der Vorteil einer solchen Ausbildung der Querträger besteht darin, daß zwei übereinanderliegende Bänder in einfacher Weise gebogen und mithin der gewünschten Gewölbekontur angepaßt sowie nach dem Biegen in der gewünschten Wölbungsform fixiert werden können, indem einfach die beiden aufeinanderliegenden Bänder durch geeignete Mittel schubfest so miteinander verbunden werden, daß sich die einzelnen Querschnitte nicht mehr gegeneinander verschieben können. Zum schub­festen Verbinden können kraft- oder formschlüssige Mittel eingesetzt werden, so beispielsweise Verbindungs­schrauben, die sich durch entsprechende Lochungen in den beiden Bändern hindurcherstrecken und in der Fixationslage diese Bänder gegeneinander verspannen.Thus, the embodiment according to claim 2 provides that the cross members consist of two superimposed and shear-resistant interconnectable bands. The advantage of such a design of the crossbeams is that two strips lying one above the other are bent in a simple manner and therefore the desired one The contour of the arch can be adapted and, after bending, fixed in the desired shape by simply connecting the two strips lying on top of one another in a shear-proof manner by suitable means so that the individual cross-sections can no longer be shifted against each other. For shear-resistant connection, non-positive or form-fitting means can be used, for example connecting screws which extend through corresponding perforations in the two bands and brace these bands against one another in the fixation position.

Eine andere kostengünstige Maßnahme besteht darin, daß eines der Bänder des Querträgers als Tragprofil und das andere als mit dem Tragprofil schubfest ver­bindbares Deckband ausgebildet ist, wobei das Deckband lediglich dem Zwecke dient, nach dem Biegen des Trag­profils dieses in der gewünschten Wölbungslage zu fixieren und ein etwaiges Rückfedern zu verhindern.Another cost-effective measure is that one of the bands of the cross member is designed as a support profile and the other as a cover band that can be connected to the support profile in a thrust-resistant manner, the cover band only serving the purpose of fixing it in the desired curvature position and bending it after the support profile has been bent to prevent any springback.

An sich können beim Aufbau der erfindungsgemäßen Unterkonstruktion Deckentrageprofile beliebiger Art eingesetzt werden. Als besonders zweckmäßig hat sich indessen die Verwendung bekannter C-Profile mit nach unten weisenden Stegen erwiesen, an denen eine unter­seitige Beplankung beispielsweise aus gebogenen Gips­kartonplatten in einfacher Weise anbringbar ist und auch die Ausbildung von Stößen zwischen aneinander­grenzenden Deckenbekleidungsplatten gelingt.As such, ceiling support profiles of any type can be used in the construction of the substructure according to the invention. However, the use of known C-profiles with webs pointing downwards has proven to be particularly expedient, on which underside planking, for example made of bent plasterboard, can be attached in a simple manner and also the formation of joints between adjoining ceiling cladding panels is successful.

Bei der Verwendung C-förmiger Deckentrageschienen gelingt auch eine besonders einfache Verbindung dieser Deckentrageschienen mit den Querträgern, indem U-förmige Kreuzverbinder mit zwei sich in Parallellage zueinander erstreckenden und durch einen Steg miteinander ver­bundenen Halteschenkelneingesetzt werden, die mit ihren Stegen die Querträger oberseitig übergreifen und deren Halteschenkel zwischen den nach oben gerichteten Tragschienenschenkeln der Deckentrageschienen hinein­ragen und die sich an den freien Enden der Tragschienen­schenkel entlangerstreckenden Halteflanschen der Deckentrageschienen formschlüssig hintergreifen.When using C-shaped ceiling support rails, a particularly simple connection is also possible Ceiling support rails with the crossbeams by using U-shaped cross connectors with two mutually parallel holding legs that are connected to each other by a web the positive ends of the holding flanges of the ceiling support rails which extend along the free ends of the support rail legs.

An embodiment of the invention will be explained below with reference to the accompanying drawings. Schematic views show:
  • 1 shows a partial cross section through an arched ceiling, which is suspended by means of a substructure according to the invention from a ceiling of the building which is only indicated,
  • 2 is a perspective view of a section of a cross member, which consists of a support profile and a cover band attached to it, which are bent according to the desired curvature and are connected to one another after bending in a shear-resistant manner,

Die Unterkonstruktion 10 der in Fig. 1 in einem Teil­querschnitt gezeigten Unterdecke 11 besteht aus in vor­bestimmten Abständen voneinander quer zur Gewölbe­längserstreckung angeordneten Querträgern 12 und unter diesen in vorbestimmten Abständen voneinander in Gewölbelängsrichtung verlaufend befestigten Decken­trageschienen 13. Die Querträger 12 sind der gewünsch­ten Gewölbeform entsprechend gebogen und mittels hier nicht weiter interessierender Abhängevorrichtungen 14 bekannter Art an der Baukörperdecke abgehängt.The substructure 10 of the partial ceiling 11 shown in FIG. 1 in a partial cross-section consists of cross members 12 arranged at predetermined distances from one another transversely to the longitudinal vault extension, and below these ceiling support rails 13 fastened at predetermined distances from one another in the longitudinal vault direction suspended from the ceiling of the building by means of suspension devices 14 of a known type that are not of further interest here.

Die in Fig. 2 veranschaulichte Ausführungsform eines Querträgers 12 besteht aus einem Tragprofil 16 und einem Deckband 17, das in einer en Querschnitts­abmessungen des Deckbandes angepaßten Profilvertiefung des Tragprofils aufgenommen ist. Das Tragprofil 16 und das Deckband 17 sind mit im gleichen Teilungsmaß gehaltenen Langlöchern 18 versehen, die einerseits einen einfachen Anschluß der in Fig. 1 nur angedeuteten Abhängevorrichtungen 14 ermöglichen und anderseits für die Aufnahme von Spannschrauben 19 dienen, um nach dem Biegen entsprechend der gewünschten Wölbung einer zu erstellenden Unterdecke das Deckband 17 schubfest mit dem Tragprofil zu verbinden und dadurch den Querträger 12 in der durch das Biegen erzeugten Wölbungsform zu fixieren.The embodiment of a cross member 12 illustrated in FIG. 2 consists of a support profile 16 and a cover band 17 which is received in a profile recess of the support profile which is adapted to the cross-sectional dimensions of the cover band. The support profile 16 and the shroud 17 are provided with elongated holes 18 held at the same pitch, which on the one hand allow easy connection of the suspension devices 14 only indicated in FIG. 1 and on the other hand serve for receiving clamping screws 19 in order to bend according to the desired curvature a shroud to be created to connect the shroud 17 with the support profile in a shear-resistant manner and thereby to fix the cross member 12 in the arch shape produced by the bending.

Bei den Deckentrageschienen 13 handelt es sich, wie insbesondere Fig. 4 zeigt, um bekannte C-Profile mit zwei durch einen Steg 20 miteinander verbundenen Profilschenkeln 21, 21ʹ und sich an den vom Steg entfernten Längskanten der Profilschenkel entlanger­streckenden, einwärts abgekanteten Halteflanschen 22, 22ʹ. Diese Deckentrageprofile 13 sind, wie Fig. 1 zeigt, in vorbestimmten Abständen voneinander und in Wölbungslängsrichtung verlaufend mit nach unten weisenden Stegen 20 an den quer zur Gewölbelängs­erstreckung an der Baukörperdecke abgehängten Quer­trägern 12 befestigt. Die Längskanten der Profil­schenkel 21, 21ʹ, an denen sich die nach innen gekan­teten Halteflanschen 22, 22ʹ entlangerstrecken, ver­laufen dann unterseitig im Abstand von den Querträgern 12.The ceiling support rails 13 are, as shown in particular in FIG. 4, known C-profiles with two profile legs 21, 21ʹ connected to one another by a web 20 and extending inwardly bent retaining flanges 22, 22ʹ on the longitudinal edges of the profile legs remote from the web . These ceiling support profiles 13, as shown in FIG. 1, are fastened at predetermined intervals from one another and in the longitudinal direction of the curvature with webs 20 pointing downwards to the cross members 12 suspended transversely to the longitudinal vault extension on the structural ceiling. The longitudinal edges of the profile legs 21, 21ʹ, on which the holding flanges 22, 22ʹ bent inward extend, then run on the underside at a distance from the cross members 12.

Zum Verbinden der Deckentrageschienen 13 mit den Querträgern 12 sind U-förmige Kreuzverbinder 24 mit zwei parallel zueinander verlaufenden und durch einen gemeinsamen Steg 25 miteinander verbundenen Halte­schenkeln 26, 26ʹ eingesetzt. In der Montagelage übergreifen diese Kreuzverbinder die der Wölbungs­form entsprechend gebogenen Querträger 12 und die Halteschenkel 26, 26ʹ erstrecken sich in die C-Profile hinein und hintergreifen deren nach innen abgekantete Halteflanschen 22, 22ʹ mit speziellen Halteabschnitten 27, 27ʹ formschlüssig. Soweit erforderlich, können die Kreuzverbinder 24 gegen unerwünschte Verschiebungen auf den gebogenen Querträgern 12 gesichert werden, beispielsweise mittels die Stege der Kreuzverbinder und die Querträger durchdringender Halteschrauben, was aber nicht gezeigt ist.To connect the ceiling support rails 13 to the cross members 12, U-shaped cross connectors 24 with two mutually parallel and connected by a common web 25 holding legs 26, 26 'are used. In the assembly position, these cross-connectors overlap the crossbeams 12 which are curved in accordance with the shape of the curvature and the holding legs 26, 26ʹ extend into the C-profiles and engage behind the holding flanges 22, 22ʹ bent inwards with special holding sections 27, 27ʹ in a form-fitting manner. If necessary, the cross connectors 24 can be secured against undesirable displacements on the curved cross members 12, for example by means of retaining screws penetrating the webs of the cross connectors and the cross members, but this is not shown.

Es ist somit eine äußerst einfach und kostengünstig herstellbare Unterkonstruktion für gewölbte Abhänge­ decken geschaffen worden, bei der die nach unten weisenden Stege 20 der an den Querträgern 12 be­festigten Deckentrageschienen 13 auf einer der ge­forderten Gewölbeform entsprechenden Bahnkurve liegen. Die der Gewölbeform entsprechend gebogenen Decken­bekleidungsplatten 28 werden dann von unten an den Stegen der Deckentrageschienen 13 angelegt und an den Deckentrageschienen befestigt, indem beispielsweise Befestigungsschrauben mit selbstschneidenden Gewinden durch die geformten Deckenbekleidungsplatten, bei denen es sich um Gipskartonplatten handeln kann, hindurch in die Stege der Deckentrageschienen ein­geschraubt werden. Diese Art der Anbringung von Gips­kartonplatten an den Stegen von Deckentrageschienen ist bekannt und bedarf keiner Erläuterung. Bekannt ist auch, daß im Bereich derartiger Decken­trageschienen unproblematisch Stoßstellen zwischen aneinandergrenzenden Deckenbekleidungsplatten ver­wirklicht werden können.It is therefore an extremely simple and inexpensive to manufacture substructure for curved slopes ceilings have been created in which the downward webs 20 of the ceiling support rails 13 fastened to the cross members 12 lie on a path curve corresponding to the required arch shape. The ceiling cladding panels 28 which are curved in accordance with the shape of the vault are then placed from below on the webs of the ceiling support rails 13 and fastened to the ceiling support rails, for example by fastening screws with self-tapping threads through the shaped ceiling cladding panels, which may be plasterboard panels, into the webs of the ceiling support rails be screwed in. This type of attachment of plasterboard to the webs of ceiling support rails is known and requires no explanation. It is also known that in the area of such ceiling support rails, joints between adjacent ceiling cladding panels can be realized without problems.
