STAND DER TECHNIKSTATE OF THE ART

Die Kederdachsysteme, die in dem Katalog "Layher Schutz-Systeme Komplettprogramm", Ausgabe 01.04.2010 beschrieben sind, können schnell und einfach für die unterschiedlichsten Anwendungen erstellt werden. Sie stellen ein leichtes und wirtschaftliches Wetterschutzdach dar. Derartige Kederdächer werden häufig bei Dachsanierung, Aufstockung, Brücken- und Autobahnbaustellen oder im Veranstaltungsbereich eingesetzt. Die einzelnen Bauteile des Kederdaches sind dabei insbesondere gewichtsmäßig so dimensioniert, dass das Kederdach in der Regel ohne Kran aufgebaut werden kann, das heißt, dass das Kederdach in Leichtbauweise erstellt werden kann.The keder roof systems used in the Catalog "Layher Protection Systems Complete Program", Edition 01.04.2010 can be quickly and easily created for a wide variety of applications. They provide a lightweight and economical weather protection roof. Such keder roofs are often used in roof renovation, rebuilding, bridge and highway construction sites or in the event area. The individual components of the Kederdaches are in particular so dimensioned in terms of weight, that the Keder roof can be constructed usually without a crane, that is, that the Keder roof can be created in lightweight construction.

Die Montage soll möglichst einfach und schnell erfolgen, was durch wenige unterschiedliche Bauteile ermöglicht wird, die einerseits hinsichtlich ihres Eigengewichts optimiert sind und andererseits bezüglich ihrer Traglast und Spannweiten unterschiedlichsten Einsatzfällen genügen.The assembly should be as simple and fast as possible, which is made possible by a few different components, which are optimized on the one hand in terms of their own weight and on the other hand meet a variety of applications with respect to their load and spans.

In der genannten Veröffentlichung ist ein Kederdachfirstträger beschrieben, der einen durchgehenden gekrümmten oder geknickten Obergurt und einen durchgehend geknickten Untergurt aufweist. In der Mitte ist zwischen den beiden Gurten ein Firststab eingeschweißt und jeweils rechts und links beabstandet zu dem Firststab ist ein Vertikalstab eingeschweißt.In the cited publication, a welted roof ridge support is described which has a continuous curved or kinked upper flange and a continuously folded lower flange. In the middle between the two straps a ridge bar is welded and each right and left spaced to the ridge bar a vertical rod is welded.

Auch die weiteren bekannten Kederdachfirstträger weisen keine Diagonalen auf, die dazu geeignet sind, die Abtragung der Biegung und Querkraft sicherzustellen. Daher treten relativ hohe Beanspruchungen insbesondere im Untergurt auf.The other known Kederdachfirstträger have no diagonal, which are suitable to ensure the removal of the bending and shear force. Therefore, relatively high stresses occur especially in the lower flange.

Aus der DE 10 2010 015 388 A1 ist ein Firstgelenk gemäß dem Oberbegriff von Anspruch 1 für ein Wetterschutzdach bekannt, das auch als Kederdach ausgebildet sein kann. Bei diesem Fistgelenk wird vornehmlich darauf abgezielt, dass im Bereich des Firstgelenkes zwei Knotenbleche vorhanden sind, die über eine Kulissenführung schwenkbar miteinander verbunden sind. Dadurch ist eine Neigungseinstellung des links und rechts ankommenden Obergurts bzw. des gesamten Fachwerkträgers möglich. Die ankommenden Untergurte sind über ein Zugglied miteinander verbunden, wobei eine Lasche verwendet wird. Somit ist ein Kederdachfirstträger mit Obergurt und Untergurt vorhanden, bei dem im Untergurtbereich ein Knotenblech angeordnet ist, um einen links und rechts ankommenden Untergurt anzuschließen, wobei allerdings ein Zugglied dazwischen geschaltet ist.From the DE 10 2010 015 388 A1 a ridge joint according to the preamble of claim 1 for a weather protection roof is known, which may also be designed as a keder roof. In this Fistgelenk is primarily intended that in the area of the ridge joint two gussets are present, which are pivotally connected to each other via a slotted guide. As a result, a tilt adjustment of the left and right incoming upper belt or the entire truss girder is possible. The incoming bottom straps are interconnected by a tension member using a tab. Thus, a Kederdachfirstträger with Obergurt and Untergurt is present, in which a gusset plate is arranged in the lower flange to connect a left and right incoming lower flange, but with a tension member is connected in between.

Die DE 35 42 610 A1 offenbart ein Schnell-Montage-Hallendach, bei dem es darum geht, dass die Obergurte der als Fachwerkträger ausgebildeten Dachbinder nach oben offene Profile aufweisen, in die von oben eingreifende Randleisten von Rahmenprofilen für die Dachhaut vorhanden sind. Es ist ganz allgemein beschrieben, dass unter anderem die Untergurte der Fachwerkträger über Knotenbleche miteinander verbunden sind. Die Ausführung speziell als Kederdach ist in dieser Druckschrift nicht beschrieben.The DE 35 42 610 A1 discloses a quick-assembly hall roof, which is concerned with the fact that the upper chords of the trusses trained roof trusses have upwardly open profiles are present in the engaging from above edge strips of frame profiles for the roof skin. It is generally described that inter alia, the lower chords of the truss girders are interconnected via gusset plates. The execution especially as a keder roof is not described in this document.

Die US 5,784,842 A offenbart ein Kederdachsystem mit Fachwerkträgern, ohne dass zur Verbindung der Fachwerkstäbe Knotenbleche eingesetzt werden. Vielmehr werden die Stäbe miteinander verschweißt.The US 5,784,842 A discloses a keder roof system with truss girders without the use of gussets for connecting the truss bars. Rather, the rods are welded together.

Aus der CA 2 241 715 A1 , FR 863 211 A , FR 863 582 A , GB 273 127 A und EP 1 227 203 A1 , die vornehmlich aus dem Bereich des klassischen Stahlbaus stammen, ist es schon seit sehr langer Zeit bekannt, die Fachwerkstäbe von Fachwerkträgern - unter anderem auch die Untergurte - mittels Knotenbleche miteinander zu verbinden.From the CA 2 241 715 A1 . FR 863 211 A . FR 863 582 A . GB 273 127 A and EP 1 227 203 A1 , which come primarily from the field of classic steel construction, it has been known for a very long time to connect the truss members of trusses - including the lower chords - using gusset plates together.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Ausgehend vom eingangs genannten Stand der Technik liegt auf der vorliegenden Erfindung die Aufgabe beziehungsweise das technische Problem zugrunde, einen Kederdachfirstträger beziehungsweise eine Kederdachträgereinrichtung der eingangs genannten Art anzugeben, der / die von der Beibehaltung einer einfachen und schnellen Montage und einer wirtschaftlichen Herstellung den statischen Erfordernissen genügt und insbesondere hohe Traglasten gewährleistet und mittels dem /derer große Spannweiten des Gesamtdaches erzielt werden können.Based on the above-mentioned prior art, the present invention has the object or the technical problem of specifying a Kederdachfirstträger or a Keder roof rack device of the type mentioned above, which satisfies the static requirements of maintaining a simple and quick installation and economic production and in particular ensures high payloads and by means of which / which large spans of the entire roof can be achieved.

Der erfindungsgemäße Kederdachfirstträger für eine Kederdachkonstruktion ist durch die Merkmale des unabhängigen Anspruchs 1 gegeben. Vorteilhafte Ausgestaltungen und Weiterbildungen sind Gegenstand der von dem unabhängigen Anspruch 1 direkt oder indirekt abhängigen Ansprüchen 1 bis 11.The Kederdachfirstträger invention for Keder roof construction is given by the features of independent claim 1. Advantageous embodiments and further developments are the subject of claims 1 to 11 directly or indirectly dependent on the independent claim 1.

Die erfindungsgemäße Kederdachträgereinrichtung ist durch die Merkmale des unabhängigen Anspruchs 12 gegeben. Vorteilhafte Ausgestaltungen und Weiterbildungen der Kederdachträgereinrichtung sind durch die Merkmale der von dem unabhängigen Anspruch 12 direkt oder indirekt abhängigen Ansprüche 13 und 14 gegeben.The Kederdachträgereinrichtung invention is given by the features of independent claim 12. Advantageous embodiments and further developments of the keder roof carrier device are given by the features of claims 13 and 14 directly or indirectly dependent on independent claim 12.

Der erfindungsgemäße Kederdachfirstträger ist demgemäß dadurch gekennzeichnet, dass das Knotenblech eine Grundplatte aufweist, an die jeweils in Längsrichtung der Untergurte eine Untergurtvorsprungeinheit angeformt ist und das Knotenblech in seinem oberen Wandbereich jeweils eine nach oben offene Ausnehmung aufweist, die an die Außenquerschnittskontur der Vertikalstäbe beziehungsweise Diagonalstäbe angepasst ist, so dass auf eine Schlitzung dieser Stäbe zum Anschluss an das Knotenblech verzichtet werden kann und diese direkt an das Knotenblech angeschlossen werden können, was eine Reduzierung der Herstellkosten ermöglicht.The Kederdachfirstträger according to the invention is accordingly characterized in that the gusset plate has a base plate, in each of which a Untergurtvorsprungeinheit is formed in the longitudinal direction of the lower straps and the gusset plate in its upper wall portion each having an upwardly open recess which is adapted to the outer cross-sectional contour of the vertical bars or diagonal bars is, so that can be dispensed with a slotting of these bars for connection to the gusset plate and they can be connected directly to the gusset plate, allowing a reduction in manufacturing costs.

Durch diese Verlängerung des Knotenblechs ist es möglich, die Schweißeinflusszone des Anschlusses der Untergurte an das Knotenblech besser zu verteilen, so dass die auftretenden Zugkräfte im Untergurt aufgenommen werden können. Dies ist insbesondere vorteilhaft bei der Verwendung von dem Material Aluminium. Des Weiteren werden einfache Anschlussmöglichkeiten gewährleistet.By this extension of the gusset plate, it is possible to better distribute the Schweißeinflusszone the connection of the lower straps to the gusset plate, so that the tensile forces can be absorbed in the lower flange. This is particularly advantageous in the use of the material aluminum. Furthermore, simple connection options are guaranteed.

Erfindungsgemäß ist der bekannte, durchgehende geknickte Untergurt, der hinsichtlich der Traglast als kritisch anzusehen ist, ersetzt worden durch zwei in diesem Bereich an ein Knotenblech angeschlossene Untergurte, wobei gemäß einer besonders bevorzugten Ausgestaltung an das Knotenblech und /oder die Untergurte jeweils ein rechter beziehungsweise ein linker Diagonalstab angeschlossen ist. Vorteilhaft ist gleichzeitig ein als zentraler, mittiger Firststab ausgebildeter Vertikalstab und jeweils ein rechts und links beabstandeter zum Firststab angeordneter weiterer Vertikalstab angeschlossen, so dass die Diagonalen insgesamt relativ nahe an den Knickpunkt herangeführt werden können und durch den Anschluss der Stäbe an das Knotenblech die Abtragung der Biegung und Querkraft sichergestellt ist, was im Ergebnis eine hohe Traglast zur Folge hat.According to the known, continuous kinked bottom flange, which is to be regarded as critical with regard to the load, has been replaced by two in this area connected to a gusset plate bottom straps, according to a particularly preferred embodiment of the gusset plate and / or the lower straps each a right or a left diagonal bar is connected. Advantageously, at the same time a trained as a central, central ridge rod vertical rod and in each case a right and left spaced to ridge staff arranged further vertical rod connected, so that the Overall, diagonals can be brought relatively close to the break point and the connection of the rods to the gusset plate, the removal of the bending and shear force is ensured, which has the result of a high load capacity.

Somit ist die Diagonalführung bei dem Kederdachfirstträger bezüglich der statischen Erfordernisse optimiert, wodurch relativ große Spannweiten des gesamten Daches erzielt werden können.Thus, the diagonal guide is optimized in the Kederdachfirstträger with respect to the static requirements, whereby relatively large spans of the entire roof can be achieved.

Eine besonders vorteilhafte Ausgestaltung zeichnet sich dadurch aus, dass der linke und rechte Untergurt einen durchgehenden Schlitz aufweist, durch den das Knotenblech hindurchgeführt ist.A particularly advantageous embodiment is characterized in that the left and right lower flange has a continuous slot through which the gusset plate is passed.

In diesem Zusammenhang ist es besonders vorteilhaft, dass das Knotenblech oberseitig der Untergurte einen Überstand aufweist, so dass genügend Platz vorhanden ist, eine Schweißnaht auszubilden.In this context, it is particularly advantageous that the gusset plate on the upper side of the lower chords has a projection, so that there is enough space to form a weld.

Die Bauteile des Kederdachfirstträgers beziehungsweise der Kederdachträgereinrichtung können beispielsweise aus Aluminium oder Stahl bestehen.The components of the Kederdachfirstträgers or the Keder roof rack means may for example consist of aluminum or steel.

Der mittige Firststab besitzt gemäß einer vorteilhaften Weiterbildung unterseitig einen nach unten offenen Schlitz, durch den hindurch das Knotenblech geführt ist, wodurch ein problemloser Schweißanschluss des Stabes an das Knotenblech ermöglicht wird.According to an advantageous further development, the central ridge bar has on the underside a downwardly open slot, through which the gusset plate is guided, whereby a problem-free welding connection of the bar to the gusset plate is made possible.

Eine besonders vorteilhafte konstruktive Ausgestaltung zeichnet sich dadurch aus, dass an das Knotenblech unterseitig eine überstehende Abspannvorsprungeinheit angeformt ist, mit Anschlussmöglichkeiten für Anschlussabspannmittel, insbesondere Seile. Die Anschlussmöglichkeiten können beipielsweise als geschlossene Ausnehmung, insbesondere als zwei beabstandete Ausnehmungen, insbesondere Löcher, ausgebildet sein. Damit ist auf der Unterseite des Kederdachfirstträgers ein Anschluss für Abspannungen vorhanden, was sich vorteilhaft für die Gesamtkonstruktion auswirkt, da bei größeren Spannweiten die Belastungsart Windsog bezüglich der Kederdachträgereinrichtung maßgebend werden kann und durch das Vorsehen einer Abspannung die in der Kederdachträgereinrichtung entstehenden Kräfte deutlich reduziert werden können. In einfacher Art und Weise bietet das über die Untergurte nach unten hinaus geführte Knotenblech die Abspannmöglichkeiten an, wobei das Knotenblech selbst in den geschlitzten Rohren des Untergurtes eingeschoben und angeschweißt ist.A particularly advantageous structural embodiment is characterized in that on the gusset plate on the underside a projecting Abspannvorsprungeinheit is formed, with connection possibilities for Anschlussabspannmittel, in particular ropes. The connection possibilities can be, for example, as a closed recess, in particular as two spaced recesses, in particular holes, be formed. This is on the underside of the Keder roof ridge support a connection for bracing available, which is advantageous for the overall design, as with larger spans the loading wind suction with respect to the Keder roof rack means can be decisive and by providing a bracing the resulting forces in the Keder roof rack means can be significantly reduced , In a simple manner, the gusset plate, which is guided downwards beyond the lower chords, offers the guying possibilities, with the gusset plate itself being inserted and welded in the slotted tubes of the lower chord.

Das Knotenblech trägt somit zur Traglasterhöhung bei, da bei der bekannten Ausführung mit einem durchgehenden Untergurt eine Biegung des Untergurts mit dem minimal möglichen Radius dazu führen würde, dass die entstehenden Umlenkkräfte zusätzliche Biegung mit der Möglichkeit des Versagens im Untergurt hervorrufen. Mit der erfindungsgemäßen Lösung unter Einsatz eines Knotenblechs mit schräg abgeschnittenen geschweißten Rohren ist dieser Nachteil nicht mehr gegeben.The gusset plate thus contributes to the increase in load, as in the known design with a continuous lower flange a bending of the lower flange with the minimum possible radius would cause the resulting deflection forces cause additional bending with the possibility of failure in the lower flange. With the solution according to the invention using a gusset plate with obliquely cut welded tubes, this disadvantage is no longer present.

Die erfindungsgemäße Kederdachträgereinrichtung ist dadurch gekennzeichnet, dass sie zumindest einen Kederdachfirstträger der oben genannten Art aufweist, wobei in beiden Endbereichen des Kederdachfirstträgers, insbesondere geradlinig verlaufende, Kederdachträger angeschlossen sein können. Durch den modularen Aufbau der Kederdachträgereinrichtung ist eine einfache Montage problemlos möglich. Die Kederdachträgereinrichtung kann auch allein durch mehrere Kederdachfirstträger gebildet werden zum Beispiel für ein sogenanntes Tonnendach.The Keder roof carrier device according to the invention is characterized in that it comprises at least one Keder roof ridge carrier of the above-mentioned type, wherein in both end regions of the Keder roof ridge carrier, in particular rectilinear, Keder roof carrier can be connected. Due to the modular design of Keder roof rack means a simple installation is easily possible. The Kederdachträgereinrichtung can also be formed solely by several Kederdachfirstträger for example, for a so-called tonneau roof.

Bevorzugt weist der Kederdachfirstträger und/oder die Kederdachträger und/oder die Kederdachtraufträger steigende und fallende Diagonalen auf, wobei jeweils zwischen einem steigenden und fallenden Diagonalenpaar ein Vertikalstab an den Ober- und Untergurt angeschlossen ist und der Abstand der Vertikalstäbe bevorzugt circa 1,0 m (Meter) beträgt. Dadurch kann die Aussteifung der Kederdachträgereinrichtungen innerhalb der Gesamtdachkonstruktion enger als bisher gewählt werden, was sich günstig auf das Traglastverhalten auswirkt.Preferably, the Kederdachfirstträger and / or the Keder roof carrier and / or KederDachtraufträger on rising and falling diagonals, each between a rising and falling falling diagonal pair a vertical rod is connected to the upper and lower belt and the distance of the vertical rods is preferably about 1.0 m (meters). As a result, the stiffening of the Keder roof carrier devices can be selected within the overall roof structure narrower than before, which has a favorable effect on the load capacity behavior.

WEGE ZUM AUSFÜHREN DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

In Fig. 1 ist in einer Perspektive schematisch ein Kederdach 10 dargestellt, das als Leichtbauwerk ausgebildet ist, das heißt, die Konstruktion des Kederdaches 10 ist so dimensioniert, dass das Dach in der Regel ohne Kran aufgebaut werden kann.In Fig. 1 schematically, a keder roof 10 is shown in a perspective, which is designed as a lightweight construction, that is, the construction of Kederdaches 10 is dimensioned so that the roof can be built usually without a crane.

Das Kederdach 10 weist die Form eines Satteldaches auf. Es sind parallel beabstandete Kederdachträgereinrichtungen 12 vorhanden, die als Fachwerkträger ausgebildet sind und in ihren Endbereichen auf speziellen Auflagerkonstruktionen 48 gelagert sind. Die Auflagerkonstruktionen 48 können über ein Spannseil 18 miteinander gekoppelt, das den Dachschub aufnimmt.The keder roof 10 has the shape of a saddle roof. There are parallel spaced keder roof support means 12 which are formed as truss girders and are mounted in their end regions on special support structures 48. The support structures 48 can be coupled together via a tensioning cable 18, which receives the roof thrust.

Die Kederdachträgereinrichtungen 12 sind über quer zu den Kederdachträgereinrichtungen 12 angeordneten Gitterträger 17 seitlich abgestützt, die eine eventuell horizontal auftretende Belastung zu einem zwischen zwei Kederdachträgereinrichtungen 12 angeordneten Diagonalenverband 19 ableiten.The keder roof support devices 12 are laterally supported by lattice girders 17 arranged transversely to the keder roof support devices 12, which derive a possibly horizontally occurring load to a diagonal connection 19 arranged between two keder roof support devices 12.

Die Kederdachträgereinrichtung 12 besteht aus folgenden Bauteilen: im Firstbereich ist ein Kederdachfirstträger 14 angeordnet, der einen Knick aufweist und an dessen Endbereichen jeweils ein Kederdachträger 16 angeschlossen ist. Im Endbereich jedes Kederdachträgers 16 ist ein Kederdachtraufträger 15 angeschlossen, der wiederum auf der Auflagerkonstruktion 48 gelagert ist.The Keder roof carrier device 12 consists of the following components: in the ridge region a Kederdachfirstträger 14 is arranged, which has a kink and at the end regions in each case a Keder roof carrier 16 is connected. In the end region of each keder roof carrier 16, a Kederdachtraufträger 15 is connected, which in turn is mounted on the support structure 48.

Der Kederdachfirstträger 14 ist in den Fig. 2 und 3 näher dargestellt. Er weist oberseitig einen durchgehenden Obergurt 42 auf, der im Bereich des Firstes gekrümmt ausgebildet ist. Unterseitig ist parallel beabstandet zum Obergurt ein linker und rechter Untergurt 44.1, 44.2 vorhanden. In der Mitte verläuft ein vertikaler Firststab 40 zwischen dem Obergurt 42 und den Untergurten 44.1,44.2. Rechts und links des Firststabes 40 sind geneigt zu dem Firststab 40 und senkrecht zu dem Obergurt 42 beziehungsweise jeweiligen Untergurt 44 jeweils ein rechter und linker Vertikalstab 36, 38 vorhanden. Im weiteren Verlauf des Kederdachfirstträgers 14 schließt sowohl im linken als auch im rechten Randbereich jeweils ein vom Untergurt 44.1 beziehungsweise 44.2 ansteigender rechter beziehungsweise linker Diagonalstab 32, 34 und daran anschließend einen weiteren rechten beziehungsweise linken Diagonalstab 33, 35 an. Il rechten beziehungsweise linken Endbereich des Kederdachfirstträgers 14 ist jeweils ein vertikal zum Obergurt 42 beziehungsweise Untergurt 44.1,44.2 verlaufender weiterer Vertikalstab 39 vorhanden. Desweiteren sind im Endbereich am Obergurt 42 und am Untergurt 44.1, 44.2 Anschlußeinheiten 52 beziehungsweise 54 vorhanden zum Anschluß eines Kederdachträgers 16.The Kederdachfirstträger 14 is in the FIGS. 2 and 3 shown in more detail. On the upper side, it has a continuous upper flange 42, which is curved in the region of the ridge. On the underside, a left and right lower flange 44.1, 44.2 is parallel to the upper flange available. In the middle, a vertical ridge bar 40 extends between the top flange 42 and the bottom straps 44.1, 44.2. Right and left of the ridge bar 40 are inclined to the ridge bar 40 and perpendicular to the top flange 42 and respective bottom flange 44 each have a right and left vertical bar 36, 38 available. In the further course of Kederdachfirstträgers 14 includes both in the left and in the right edge region in each case from the lower flange 44.1 and 44.2 increasing right or left diagonal bar 32, 34 and then a further right or left diagonal bar 33, 35 at. Il right or left end of the Keder Roof ridge carrier 14 is a vertically to the upper flange 42 and lower flange 44.1,44.2 extending further vertical rod 39 is present. Furthermore, in the end region on the top flange 42 and on the bottom flange 44.1, 44.2, connection units 52 and 54 are present for connecting a keder roof carrier 16.

Im Gegensatz zu dem bekannten Kederdachfirstträger weist der anmeldegemäße Kederdachfirstträger 14 somit insgesamt fünf Vertikalstäbe und zwei steigende und fallende Diagonalenpaare auf. Weiterhin ist im Firstbereich im Bereich der Untergurte 44.1, 44.2 ein Knotenblech 20 vorhanden, an dem sowohl der von links als auch der von rechts ankommende Untergurt 44.1,44.2, der Firststab 40, der linke und rechte Vertikalstab 36, 38 und der linke und rechte Diagonalstab 32, 34 angeschlossen ist (siehe Fig. 3). Der Anschluß sämtlicher Stäbe ist als Schweißanschluß ausgebildet. Sämtliche Bauteile bestehen im Ausführungsbeispiel aus Aluminium. Die geknickte Längsrichtung des Kederdachfirstträgers ist in Fig. 2 mit dem Bezugszeichen L angegeben.In contrast to the known Kederdachfirstträger of registration Kederdachfirstträger 14 thus has a total of five vertical bars and two rising and falling diagonal pairs. Furthermore, in the ridge region in the region of the lower chords 44.1, 44.2, there is a gusset plate 20 on which both the left and the right lower chords 44.1, 44.2, the ridge bar 40, the left and right vertical bars 36, 38 and the left and right Diagonal bar 32, 34 is connected (see Fig. 3 ). The connection of all rods is designed as a welding connection. All components are made in the embodiment of aluminum. The kinked longitudinal direction of the Keder roof ridge carrier is in Fig. 2 indicated by the reference L.

Die geometrische Form des Knotenblechs 20 ist in Fig. 4 dargestellt. Das Knotenblech 20 besitzt eine Grundplatte 46, die im oberen Bereich an den geknickten Verlauf angepasst ist, wobei die Längsachsen der anzuschließenden Untergurte 44.1, 44.2 mit U bezeichnet sind. In Richtungs der Achsen U ist an die Grundplatte 46 des Knotenblechs 20 jeweils eine Untergurtvorsprungseinheit 22.1 beziehungsweise 22.2 angeformt. Unterseitig ist an die Grundplatte 46 in Form einer wellenförmigen Aussenkontur eine Abspannvorsprungeinheit 24 angeformt, die zwei beabstandet angeordnete durchgehende Abspannausnehmungen 26 aufweist, so dass es in einfacher Art und Weise möglich ist, an den Abspannausnehmungen 26 jeweils ein Abspannelement, zum Beispiel ein Seil, anzuschließen, um die Dachkonstruktion gegen Windsog abzusichern.The geometric shape of the gusset plate 20 is in Fig. 4 shown. The gusset plate 20 has a base plate 46, which is adapted to the kinked curve in the upper region, wherein the longitudinal axes of to be connected lower straps 44.1, 44.2 are designated by U. In the direction of the axes U, a Untergurtvorsprungseinheit 22.1 and 22.2 is integrally formed on the base plate 46 of the gusset plate 20 respectively. On the underside of the base plate 46 in the form of a wave-shaped outer contour a Abspannvorsprungeinheit 24 is formed, which has two spaced Abspannausnehmungen 26 so that it is possible in a simple manner to connect to the Abspannausnehmungen 26 each a guy element, for example a rope to protect the roof structure against wind suction.

Die Achsen des Firststabes 40 sind in Fig. 2 mit F bezeichnet, die Achsen der Vertikalstäbe mit V und die Achsen der Diagonalstäbe mit D.The axes of the ridge bar 40 are in Fig. 2 denoted by F, the axes of the vertical bars with V and the axes of the diagonal bars with D.

Oberseitig besitzt das Knotenblech 20 im Bereich der Achsen V beziehungsweise D jeweils beidseitig eine erste und zweite nach oben offene Ausnehmung 28, 30, wobei beide Ausnehmungen 28, 30 bezüglich ihrer Breite an die Breite des anzuschließenden Vertikalstabes 36, 38 beziehungsweise Diagonalstabes 32, 34 angepaßt ist. Die Ausnehmungen 28, 30 besitzen eine Tiefe Ü. Um dieses Mass Ü steht das eingesetzte Knotenblech 20 über den Untergurt 44.1,44.2 über, was weiter unten beschrieben ist.On the upper side, the gusset plate 20 in the region of the axes V and D respectively on both sides a first and second upwardly open recess 28, 30, wherein both recesses 28, 30 adjusted with respect to their width to the width of the connected vertical bar 36, 38 and diagonal bar 32, 34 is. The recesses 28, 30 have a depth Ü. To this measure Ü is the used gusset plate 20 via the lower flange 44.1,44.2 on, which is described below.

Der geschweißte Anschluß der jeweiligen Stäbe beziehungsweise des Untergurts ist in Fig. 3 schematisch dargestellt.The welded connection of the respective bars or the lower chord is in Fig. 3 shown schematically.

Die Untergurte 44.1, 44.2 und der Firststab 40 weisen einen Schlitz auf, durch den das Knotenblech 20 hindurch geführt ist bis es um das Mass Ü über den Untergurt 44.1, 44.2 übersteht. In diesem eingesetzten Zustand ragt das Knotenblech 20 mit seiner Abspannvorsprungeinheit 24 unterseitig über die Untergurte 44.1 hinaus. Der Firststab 40 ist über das Niveau der Untergurte 44.1, 44.2 hinausgeführt, so dass die Untergurte 44.1, 44.2 aussenseitig an den Firststab 40 angeschlossen werden können.The lower straps 44.1, 44.2 and the ridge bar 40 have a slot through which the gusset plate 20 is passed through it to the measure Ü on the lower flange 44.1, 44.2 protrudes. In this inserted state, the gusset plate 20 projects beyond its lower girths 44.1 with its tensioning projection unit 24 on the underside. The ridge bar 40 is led beyond the level of the lower chords 44.1, 44.2, so that the lower chords 44.1, 44.2 can be connected to the ridge bar 40 on the outside.

Der rechte und linke Diagonalstab 32, 34 wird dann in die Ausnehmung 28 eingesetzt und mit dem Knotenblech 20 beziehungsweise dem Untergurt 44.1, 44.2 verschweißt. Entsprechend wird der rechte und linke Vertikalstab 36, 38 jeweils in die Ausnehmung 30 eingeführt und mit dem Knotenblech 20 und dem Untergurt 44.1, 44.2 verschweißt.The right and left diagonal bar 32, 34 is then inserted into the recess 28 and welded to the gusset plate 20 and the lower flange 44.1, 44.2. Accordingly, the right and left vertical bars 36, 38 are respectively inserted into the recess 30 and welded to the gusset plate 20 and the lower flange 44.1, 44.2.

Die Untergurtvorsprungeinheit 22.1,22.2, die bereichsweise um das Mass Ü über die Oberseite des Untergurts 44.1, 44.2 hinaussteht ist über eine Schweißnaht mit dem Untergurt 44.1, 44.2 verbunden. Dadurch, dass aufgrund der Untergurtvorsprungeinheit 22.1, 22.2 eine relativ große Länge zur Verfügung steht, kann die Schweißnaht nur einseitig angebracht werden, so dass eine Konzentration von Schweißnähten vermieden wird, was einem möglichen Verzug und oder einer negativen Materialbeeinflussung entgegenwirkt.The Untergurtvorsprungeinheit 22.1,22.2, the area by the measure Ü over the top of the lower belt 44.1, 44.2 out is connected via a weld with the lower flange 44.1, 44.2. Due to the fact that a relatively large length is available due to the lower flange projection unit 22.1, 22.2, the weld seam can be attached only on one side, so that a concentration of welds is avoided, which counteracts possible distortion and or negative material influencing.

Durch das Vorsehen der dargestellten Knotenblechkonstruktion wird gegegnüber dem bekannten durchgehenden, geknickten Untergurt die Traglast deutlich erhöht, so dass Dachkonstruktionen mit größeren Spannweiten möglich sind.By providing the gusset plate construction shown, the payload is significantly increased in comparison to the known continuous, kinked lower girder, so that roof constructions with larger spans are possible.
