Description

Trageisen für Betondecken. Die Erfindung betrifft eine Ankerschiene, welche gleichzeitig zur Aufnahme von Lasten und Bewehrungseisen für Beton und Eisenbetonkonstruktionen dient, innen hohl und einseitig mit einem durchgehenden Schlitz versehen ist.Carrying iron for concrete ceilings. The invention relates to an anchor rail, which at the same time for the absorption of loads and reinforcement iron for concrete and reinforced concrete structures serves, is hollow on the inside and provided with a continuous slot on one side.

Der Erfindung gemäß werden die den Schlitz begrenzenden Tragschenkel des Profileisens unter einem Winkel geneigt hergesteJat, und in die so gebildete Rinne greifen die mit entsprechenden Rippen versehenen Bolzenköpfe mit tunlichst geringem Spielraum ein. Hierdurch wird eine günstige Beanspruchung der Schiene und ein unbedingtes Anpassen der Bolzenköpfe an die Innenseiten der Schiene erzielt. Bei Schienen mit an der Unterseite wagerechten Tragschenkeln werden diese ungünstig auf A.bscherung und Biegung beansprucht; die Anpassung der Bolzenköpfe ist nicht immer genau. Die besondere Querschnittsform der neuen Schiene und . der Bolzenköpfe hindern die Schenkel an seitlichem Ausweichen. Durch die Zugkraft der Bolzen werden die Tragschenkel lediglich auf Abscherung beansprucht. Zur Durchführung der Verankerungseisen hat die Schiene im Steg Aufstanzungen.According to the invention, the support legs delimiting the slot of the profile iron inclined at an angle, and into the one thus formed The bolt heads, which are provided with corresponding ribs, grip the gutter as much as possible little margin. This is a favorable stress on the rail and an unconditional adaptation of the bolt heads to the inside of the rail is achieved. In the case of rails with horizontal support legs on the underside, these are unfavorable stressed on sloping and bending; the adjustment of the bolt heads is not always accurate. The special cross-sectional shape of the new rail and. the bolt heads prevent the thighs from giving way to the side. Due to the tensile force of the bolts the support legs are only subjected to shearing. For carrying out the anchoring irons the rail has punched holes in the bridge.

Die Abbildung zeigt die Schiene im Querschnitt und den Bolzen.The figure shows the rail in cross section and the bolt.
