Description
Stahlverbundträger mit vorgespannter Stahlbetonplatte Das Patent 920 851 betrifft einen Stahlträger in Verbundbauweise mit vorgespannter Stahlbetonplatte, bei dem zur Aufnahme der Schubkräfte durch Löcher im oberen Stegblechrand quer zum Träger Stahlstäbe gezogen und angespannt sind. Die Betonplatte wird an Ort und Stelle betoniert und nach dem Erhärten zum Herstellen eines sicher wirkenden Verbundes mittels der Spannglieder gegen den Steg des Stahlträgers gepreßt.Composite steel girder with prestressed reinforced concrete slab The patent 920 851 relates to a composite steel girder with a prestressed reinforced concrete slab, in which to absorb the shear forces through holes in the upper web plate edge across the Beams of steel rods are drawn and tensioned. The concrete slab is in place concreted and after hardening to create a reliable bond pressed against the web of the steel beam by means of the tendons.
In manchen Fällen ist es erwünscht, die Betonplatte zur Vereinfachung der Arbeiten auf der Baustelle als Fertigteil einzubauen. Bei Verwendung von Stahlbetonfertigplatten werden diese gemäß dem Zusatzpatent 1040 061 unter Freilassen einer Fuge zwischen sich und dem Stahlträgersteg oder dem Obergurtsteg eines Fachwerkträgers verlegt, die zum Vorspannen benötigten Spannglieder in entsprechenden Aussparungen der Platte und des Stahlträgersteges eingezogen und anschließend die Fugen mit Beton ausgefüllt. Nach Erhärten dieses zuletzt eingebrachten Betons wird, wie im Hauptpatent beschrieben, vorgespannt und damit der erwünschte Verbund hergestellt.In some cases it is desirable to install the concrete slab as a prefabricated part to simplify the work on the construction site. When using prefabricated reinforced concrete slabs, these are laid in accordance with additional patent 1 040 061 leaving a gap between you and the steel girder web or the top chord web of a lattice girder, the tendons required for prestressing are drawn into corresponding recesses in the plate and the steel girder web and the joints are then filled with concrete. After this concrete, which was introduced last, has hardened, it is prestressed, as described in the main patent, and the desired bond is thus established.
Die Erfindung bezweckt eine weitere Ausbildung eines nach dem Verfahren nach einem der Ansprüche 1 bis 5 des Patentes 1040 061 mit vorgespannter, den Trägerobergurt bildender Stahlbetonplatte hergestellten Stahlverbundträgers. Sie besteht darin, daß der Trägeruntergurt in gleicher Weise wie der Trägerobergurt ausgebildet und zusätzlich in Längsrichtung des Stahlträgersteges vorgespannt ist.The invention aims at a further development of a steel composite girder produced according to the method according to one of claims 1 to 5 of patent 1 040 061 with a prestressed reinforced concrete slab forming the upper girder flange. It consists in the fact that the lower girder chord is designed in the same way as the upper girder chord and is additionally pretensioned in the longitudinal direction of the steel girder web.
Hierdurch können beispielsweise bei Bogenträgern die sonst erforderlichen Zugbänder zur Aufnahme des Bogenschubes entfallen. Ferner ist die Erfindung insbesondere bei Shedkonstruktionen von Bedeutung.In this way, for example in the case of arch supports, the otherwise required There is no need for drawstrings to take up the bow thrust. Furthermore, the invention is particular important for shed constructions.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Querschnitt dargestellt-Der Zuggurt des Stahlverbundträgers ist aus Stahlbetonfertigteilen 14 hergestellt, die unter Freilassen einer Fuge 6 a verlegt sind. Auf die Breite des Fugenraumes ist zur Vermeidung einer Haftung des Fugenfüllbetons an dem durch die Hohlräume 4a der Platte geführten Spannglied 3 a ein kurzes Rohrstück 5 a über das Spannglied geschoben. Zur Überbrückung der Betonzugspannungen ist der Untergurt in Längsrichtung des Stahlträgersteges 2a mittels der Spannglieder 15 vorgespannt.The drawing shows an exemplary embodiment of the subject matter of the invention Shown in cross section - The tension chord of the composite steel girder is made of precast reinforced concrete 14 made, which are relocated leaving a joint 6 a. On the breadth of the joint space is to avoid adhesion of the joint filler to the through the cavities 4a of the plate guided clamping member 3 a a short pipe section 5 a over the tendon pushed. The lower chord is used to bridge the tensile stresses in the concrete Prestressed in the longitudinal direction of the steel girder web 2a by means of the tendons 15.
