PATENTAMT.PATENT OFFICE.
Durch die amerikanische Patentschrift 389951 sind Träger bekannt geworden, welche aus mehreren neben einander liegenden Lamellen bestehen, die durch Schraubenbolzen zu einem einzigen Träger verbunden sind und durch Stehbolzen in einem gewissen Abstand von einander gehalten werden.By American patent 389951 carriers have become known, which consist of several lamellas lying next to each other exist, which are connected by bolts to form a single carrier and through Stud bolts are kept at a certain distance from each other.
Vorliegende Erfindung bezieht sich auf derartige Lamellenträ'ger und hat die Innenversteifung derselben ohne besondere Vergröfserung des Gewichtes zum Zweck. Diese Innenversteifung wird dadurch erzielt, dafs die die einzelnen Lamellen verbindenden Schraubenbezw. Stehbolzen durch im Wesentlichen in der Längsrichtung des Trägers laufende Zugorgane mit einander verbunden werden, d. h. dafs diese Stehbolzen als Stütz- oder Angriffspunkte für ein nach der ganzen Länge des Trägers, und zwar abwechselnd oberhalb und unterhalb der Bolzen geführtes und an den Endstehbolzen festgelegtes Zugorgan dienen.The present invention relates to such lamellar carriers and has the internal stiffening the same without any particular increase in weight for the purpose. This inside stiffener is achieved by the fact that the screws and bolts connecting the individual lamellae. Stud bolts through tension members running essentially in the longitudinal direction of the girder be connected to each other, d. H. that these studs serve as points of support or attack for one after the entire length of the carrier, namely alternately above and below the bolt and led to the End studs serve as a fixed tension member.
Um die bei einer Durchbiegung des Trägers in den Zugorganen auftretenden Spannungen nicht zu grofs werden zu lassen, werden diese Zugmittel vortheilhaft im Zickzack geführt.About the stresses that occur in the tension members when the beam is bent In order not to allow them to become too large, these traction means are advantageously zigzagged guided.
Die beiliegende Zeichnung zeigt solche Träger, und zwar inThe accompanying drawing shows such carriers, namely in
Fig. ι als Bauglieder einer Dach- und Deckenconstruction, währendFig. Ι as structural members of a roof and ceiling construction, while
Fig. 2 einen Deckenträger im Querschnitt veranschaulicht.Fig. 2 illustrates a ceiling beam in cross section.
Jeder Träger besteht, wie bekannt, aus einer Anzahl Lamellen 1, welche durch Schraubenbolzen 2 mit Hülfe der als Stehbolzen dienenden geflantschten Hülsen 3 zu einem Ganzen verbunden sind.Each carrier consists, as is known, of a number of lamellas 1, which by screw bolts 2 with the help of the flanged sleeves 3 serving as studs to one Whole are connected.
Die Innenversteifung der Träger erfolgt durch Zugorgane 10, wie Stäbe, Drähte, Drahtseile und dergl., welche entweder, wie dies die Zeichnung zeigt, abwechselnd oberhalb und unterhalb der Schraubenbolzen 2 oder der Stehbolzen 3 geführt und an den Endbolzen festgelegt sind, oder diese Bolzen unmittelbar mit einander verbinden.The internal stiffening of the carrier is carried out by tension members 10, such as rods, wires, wire ropes and the like. Which either, as the drawing shows, alternately above and guided below the screw bolts 2 or the stud bolts 3 and attached to the end bolts are set, or connect these bolts directly with each other.
Der Zeichnung nach (Fig. 1) sind die Schraubenbolzen 2 in einer auf- und absteigenden Linie, also gegen einander versetzt angeordnet, so dafs das zwischen den Lamellen befindliche Zugorgan 10 im Zickzack läuft und dadurch die auf es wirkende Zugcomponente verkleinert wird.According to the drawing (Fig. 1), the screw bolts 2 are in an ascending and descending order Line, thus arranged offset from one another, so that that between the lamellae located tension member 10 runs in zigzag and thereby the tension component acting on it is reduced.
Die Schraubenbolzen 2 können bei der dargestellten Dachconstruction auch dazu dienen, die Träger 7 mit dem Sparren 5 durch Zugorgane 9, sowie die Träger 7 unter einander zu verbinden, im letzteren Falle zu dem Zwecke, um seitliche Verschiebungen' oder Schwankungen zu verhindern.The screw bolts 2 can also be used in the roof construction shown to the carrier 7 with the rafter 5 by tension members 9, and the carrier 7 with each other to connect, in the latter case for the purpose of lateral displacements' or To prevent fluctuations.
Auch die Pfetten 6 sind als Lamellenträger, und zwar als zweitheilige ausgebildet. In der Mitte des linken Dachsparrens ist dessen Querschnitt eingezeichnet.The purlins 6 are also designed as lamellar carriers, specifically as two-part. In the The cross-section of the left rafter is shown in the middle.
Für die Decke ist ein dreitheiliger Lamellenträger 7 gedacht, welcher oben und unten
durch Auflagen 4 abgedeckt ist und den
Bretterboden 8 trägt.A three-part lamellar support 7 is intended for the ceiling, which is above and below
is covered by conditions 4 and the
Wooden floor 8 carries.
