Description
Die Erfindung betrifft einen Lagerkörper aus Stahlbeton für Brücken oder Bauten aller Art aus Stahl oder Stahlbeton.The invention relates to a bearing body made of reinforced concrete for bridges or buildings of all kinds made of steel or reinforced concrete.
Die Erfindung bezweckt den Ersatz der aus hochwertigem Stahlguß bestehenden Lagerkörper durch solche aus Stahlbeton, die in der Herstellung und Wartung billiger sind.The invention aims to replace the existing high-quality cast steel Bearing bodies by those made of reinforced concrete, which are cheaper to manufacture and maintain are.
Solche Lagerkörper aus Stahlbeton sind an sich bekannt. Sie bestehen aus zwei Betonquadern, deren Wälzflächen mit je einem Blech verkleidet sind, das mit den Stahlteilen nicht verbunden und gegen welche der Beton gestampft wird. Der Zweck dieser Bauweise besteht darin, daß die Verkleidungsbleche den Druck unmittelbar auf den Beton übertragen, ohne daß der gedrückte Beton seitlich ausweichen kann. Da die Wälzflächen der Quader und damit auch die Verkleidungsbleche eine konvexe bzw. konkave Krümmung aufweisen, ist bei dem konvex gekrümmten Verkleidungsblech der auf Druck beanspruchte Beton in geringem Umfang gegen seitliches Ausweichen gesichert. Im Bereich des konkav gekrümmten Verkleidungsbleches dagegen besteht diese Sicherung nicht. Eine Sicherung in der Zugzone ist überhaupt nicht vorgesehen.Such bearing bodies made of reinforced concrete are known per se. You insist made of two concrete blocks, the rolling surfaces of which are each clad with a sheet of metal, the not connected to the steel parts and against which the concrete is tamped. Of the The purpose of this type of construction is that the cladding panels apply the pressure directly transferred to the concrete without the pressed concrete being able to give way to the side. Since the rolling surfaces of the cuboids and thus also the cladding sheets are convex or concave curvature, is in the convex curved cladding sheet the pressure stressed concrete to a small extent against sideways deflection secured. In the area of the concavely curved cladding sheet, on the other hand, there is this backup does not. There is no provision at all for securing in the pulling zone.
Die Lagerkörper nach der Erfindung dagegen sind so ausgebildet, daß sie Querkräfte aufzunehmen imstande sind, durch die sie auf Biegung beansprucht werden.The bearing body according to the invention, however, are designed so that they are able to absorb transverse forces through which they are subjected to bending will.
Dies wird erfindungsgemäß dadurch erreicht, daß an der der Wälzfläche entgegengesetzt liegenden Stirnfläche des Lagerkörpers ebenfalls eine Stahlplatte angeordnet ist und daß die Stahlplatten in der Druck-und Zugzone U-förmig oder tellerartig abgebogene Ränder haben, die den Lagerkörper umfassen.This is achieved according to the invention in that on the rolling surface opposite end face of the bearing body is also a steel plate is arranged and that the steel plates in the compression and tension zone are U-shaped or plate-like have bent edges that encompass the bearing body.
Durch diese Maßnahme wird ein Aufreißen und Abspringen des Betons in der Zugzone verhindert. Dasselbe gilt auch für die Druckzone, so daß der Lagerkörper größere Kräfte aufnehmen kann.This measure causes the concrete to tear and crack prevented in the tensile zone. The same also applies to the pressure zone, so that the bearing body can absorb greater forces.
Zur Erhöhung dieser Wirkung verbindet man zweckmäßigerweise die Ränder der beiden Stahlplatten durch an ihnen angeschweißte Rundstähle od. dgl.To increase this effect, it is expedient to connect the edges of the two steel plates by round bars welded to them or the like.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt, und zwar zeigt Abb. i ein beispielsweise für Balkenbrücken gebräuchliches, zweiteiliges Lager in lotrechtem Schnitt und Abb. 2 einen um go° versetzten lotrechten Schnitt durch das Lager nach der Linie A -B der Abb. i.An exemplary embodiment of the invention is shown schematically in the drawing shown, namely Fig. i shows a common example for girder bridges, two-part bearing in a vertical section and Fig. 2 a vertical offset by go ° Section through the bearing along the line A -B in Fig. I.
Gemäß den beiden Abbildungen besteht das Lager aus den beiden Teilen I und II, die je eine Trapezform haben. In der Zugzone sind die Lagerkörper I und II mit je einem Stahlblech 2 versehen, dessen die Lagerkörper allseitig umfassenden Ränder 2a U-förmig oder tellerartig abgebogen sind. In der Druckzone sind die Lagerkörper I, II auch mit je einem Stahlblech 5 versehen, dessen Ränder 5 a ebenfalls U-förmig oder tellerartig abgebogen sind. Die freien Enden der abgebogenen Stahlbleche ?,a, 5 a sind durch angeschweißte Rundstähle 3 in beliebiger Anzahl miteinander verbunden. Der Kern der Lagerkörper I, II kann durch eine oder mehrere schraubenförmig verlaufende Bewehrungen 6 verstärkt werden. Außerdem können die Stahlplatten 2, 5 durch angeschweißte Rundstähle 9 miteinander verbunden sein. Die Stähle 8 dienen zum Transport und Einbau der Lagerkörper.According to the two figures, the bearing consists of the two parts I and II, each of which has a trapezoidal shape. The bearing bodies I and are in the tensile zone II each provided with a steel sheet 2, which encompasses the bearing body on all sides Edges 2a are U-shaped or bent like a plate. The bearing bodies are in the pressure zone I, II each also provided with a steel sheet 5, the edges 5a of which are also U-shaped or are bent like a plate. The free ends of the bent steel sheets?, A, 5 a are connected to one another in any number by welded round bars 3. The core of the bearing body I, II can be one or more helically extending Reinforcements 6 are reinforced. In addition, the steel plates 2, 5 can be welded by Round bars 9 be connected to one another. The steels 8 are used for transport and installation the bearing body.
