Description

Diagonalenanschluß bei Dreigurtträgern Die Erfindung bezieht sich auf einen Dreigurtträger, bei dem ein Gurt durch ein einstegiges Profil oder durch ein nach der Momentenebene ausgerichtetes Blech gebildet wird. Vorzugsweise kommen Dreigurtträger in Betracht, deren Unter- oder Obergurt durch ein Doppel-T-Profil gebildet wird. Die Erfindung bezweckt, den Anschluß der Fachwerkscheiben des Dreigurtträgers an das Blech bzw. an den Steg des betreffenden Gurtes so zu gestalten, daß sich ein möglichst günstiger Kraftfluß ergibt. Dies wird erfindungsgemäß dadurch erreicht, daß an dem Blech beiderseits ein Formstück mit etwa keilförmigem Querschnitt befestigt ist, welches einen dünnen, in Richtung der geneigten Fachwerkscheibe verlaufenden Schenkel hat, an dem ein Knotenblech zum Anschließen von Fachwerkstäben stumpf angeschweißt ist.Diagonal connection in three-belt girders The invention relates to on a three-belt girder, in which a belt through a single-web profile or through a sheet is formed that is aligned with the plane of moments. Preferably come Three-chord girders are considered, the lower or upper chord through a double-T profile is formed. The aim of the invention is to connect the truss discs of the three-chord girders on the sheet metal or on the web of the belt in question to be designed so that the most favorable possible power flow results. According to the invention, this is achieved by that a shaped piece with an approximately wedge-shaped cross-section is attached to the sheet metal on both sides is, which is a thin, running in the direction of the inclined truss Has leg to which a gusset plate for connecting truss rods is butt welded is.

In der Zeichnung ist als Ausführungsbeispiel des Erfindungsgegenstandes der untere Teil eines Dreigurtträgers im Querschnitt dargestellt.In the drawing is an exemplary embodiment of the subject matter of the invention the lower part of a three-belt girder shown in cross section.

Der Untergurt des Dreigurtträgers besteht aus einem Doppel-T-Profil 1. An dem Steg dieses Trägers sind zwei Formstücke 2 aus Stahlguß angenietet. Jedes dieser Formstücke hat einen Schenkel 3, der sich in Richtung einer Fachwerkscheibe des Dreigurtträgers erstreckt. Die Anordnung ist so getroffen, daß sich die Mittelebenen 4, 5 der beiden Fachwerkscheiben im Schwerpunkt S des Doppel-T-Profils 1 schneiden. Die Schenkel 3 verjüngen sich auf die Dicke von Knotenblechen 6, die mit Schweißnähten 7 stumpf an die Schenkel 3 angeschweißt sind und an welche Fachwerkstäbe des Dreigurtträgers angenietet sind.The lower chord of the three-chord girder consists of a double-T profile 1. Two shaped pieces 2 made of cast steel are riveted to the web of this girder. Each of these shaped pieces has a leg 3 which extends in the direction of a truss disk of the three-chord girder. The arrangement is made in such a way that the central planes 4, 5 of the two half-timbered panels intersect in the center of gravity S of the double-T profile 1. The legs 3 taper to the thickness of gusset plates 6 which are butt welded to the legs 3 with welds 7 and to which truss rods of the three-chord girders are riveted.

Die Knotenbleche 6 sind mit dem Untergurt 1 außerdem durch ein Querblech 8 verbunden, das in den oberhalb des Untergurts 1 befindlichen Raum eingesetzt ist, sowie durch zwei Aussteifungsbleche 9, die an die Außenseiten der Knotenbleche 6 sowie an die Oberseite der unteren Gurtflansche angesetzt sind. Die Bleche 8 und 9 sind mit dem Untergurt 1 und den Knotenblechen 6 an Flanschen 11 mit Hilfe von Nieten angeschlossen.The gusset plates 6 are also connected to the lower chord 1 by a transverse plate 8 connected, which is inserted into the space located above the lower chord 1, as well as by two stiffening plates 9, which are attached to the outer sides of the gusset plates 6 and are attached to the top of the lower belt flanges. The sheets 8 and 9 are with the lower chord 1 and the gusset plates 6 on flanges 11 with the help of Rivets attached.

Die Formstücke 2 gehen von ihren Oberseiten aus in die Schenkel 3 mit Hohlkehlen über, wodurch Rinnen 10 gebildet werden. Vorzugsweise haben die Rinnen 10 in Längsrichtung des Untergurts 1 Gefälle. Sie dienen somit zum Abführen von Regenwasser.The shaped pieces 2 extend into the legs 3 from their upper sides with fillets over, whereby grooves 10 are formed. Preferably the gutters 10 in the longitudinal direction of the lower chord 1 slope. They thus serve to discharge Rainwater.

Die Formstücke 2 können auch durch Schmieden oder Pressen hergestellt sein. Die Erfindung ist auch anwendbar, wenn der Gurt irgendein anderes einstegiges Profil, z. B. ein T-Profil hat oder wenn er aus einem einfachen lotrechten Blech besteht.The shaped pieces 2 can also be produced by forging or pressing be. The invention is also applicable when the belt is any other single-legged Profile, e.g. B. has a T-profile or if it is made of a simple vertical sheet metal consists.

Es liegt naturgemäß auch im Rahmen der Erfindung, wenn der betreffende Gurt des Dreigurtträgers nicht den Unter- oder den Obergurt bildet, sondern für den Fall, daß der Dreigurtträger in waagerechter Ebene wirkende Momente aufzunehmen hat, seitwärts mit waagerechtem Blech bzw. Steg angeordnet ist.It is of course also within the scope of the invention if the relevant The belt of the three-belt girder does not form the lower or upper belt, but rather for the case that the three-belt girder absorb moments acting in the horizontal plane has, is arranged sideways with a horizontal plate or web.

Die Erfindung bringt vor allem den Vorteil, daß mit geringstem konstruktivem Aufwand ein insbesondere für hochbelastete Dreigurtträger erforderlicher, günstiger Kraftfluß ohne Exzentrizitäten für eine genietete Verbindung zwischen Diagonalen und Gurt erzielt wird.The invention has the particular advantage that with very little structural Expenditure is more favorable, which is necessary in particular for heavily loaded three-belt girders Power flow without eccentricities for a riveted connection between diagonals and strap is achieved.
