Description

Im Patent 895 825 sind Metallschalungsträger für Stahlstein- und Stahlbetonkonstruktionen sowie Verfahren zur Ein- und Ausrüstung mittels solcher Schalungsstücke beschrieben. Dabei handelt es sich um kurze Trägerstücke, die so eingerichtet sind, daß sie sich mit einfachen Mitteln zu raumüberspannenden Schalungsträgern zusammensetzen lassen. Die Deckenschalung bzw. die als Deckenschalung dienenden Steine oder Formstücke werden auf ihnen verlegt. Die Schalungsträger sind nach Fertigstellung und Erhärten der Decke leicht zu entfernen. Die Schalungsträger des Patents 895 825 sind als kurze Stücke ausgebildet, die im Obergurt mit ihren Stirnen aneinandergestoßen und im Untergurt durch verstellbare Befestigungsmittel zusammengeschlossen werden.In the patent 895 825 are metal formwork beams for steel stone and reinforced concrete structures as well as methods for fitting and equipping by means of such formwork pieces are described. These are short pieces of support that are set up so that they Can be assembled using simple means to form formwork beams that span the room. The ceiling formwork or the stones or shaped pieces used as ceiling formwork are laid on them. The formwork beams are after completion and hardening easy to remove from the ceiling. The formwork supports of the patent 895 825 are as short pieces formed, the foreheads butted together in the upper belt and be joined together in the lower chord by adjustable fasteners.

Um den Schalungsträger möglichst leicht zu machen, muß der Obergurt bei möglichst geringem Gewicht eine ausreichende Knick- und Beulsicherheit haben. Das läßt sich dadurch erreichen, daß der Obergurt mit einer oder mehreren parallel nebeneinanderliegenden Längssicken versehen wird. Sie können auch gegeneinander versetzt angeordnet sein und sind in der Längsrichtung in angemessenen Abständen unterbrochen, um die Quersteifigkeit des Trägers zu gewährleisten. Der gegenseitige Abstand der Sicken wird auf Grund statischer Berechnung zweckmäßigerweise so gewählt, daß das Material voll ausgenutzt wird und der Bereich zwischen den Sicken die erforderliche Beinsicherheit hat. In der Zeichnung zeigt Fig. i in Draufsicht einen mit den erfindungsgemäßen Sicken versehenen Obergurt, Fig. 2 einen (Querschnitt durch den Obergurt.In order to make the formwork beam as light as possible, the top chord must have sufficient buckling and buckling resistance with the lowest possible weight. This can be achieved in that the top chord with one or more parallel adjacent longitudinal beads is provided. You can also play against each other be staggered and spaced appropriately lengthways interrupted to ensure the transverse rigidity of the beam. The mutual The distance between the beads is expediently selected on the basis of static calculations so that that the material is fully used and the area between the beads the required Has leg security. In the drawing, FIG. I shows a plan view of one with the inventive Upper chord provided with beads, Fig. 2 a (cross section through the upper chord.
