Abstract

Bei einer Schalung für Serienfertigteile aus Spannbeton, - vor­ nehmlich für im Spannbett hintereinander herzustellende Weichen­ schwellen-, aufgebaut aus zwei Seitenteilen mit dazwischen eingepaßter Bodenplatte und Abstellungen, die die Länge der Einzelelemente begrenzen, werden alle Teile der Abstellvorrichtung so ausgebildet, daß sie von oben in die Schalung einsetzbar und nach dem Betonieren aus der Schalung (2) entfernbar sind. Dies wird erreicht, indem die Abdichtungen (19), die zwischen den Schottplatten (8) eingepaßt sind, längslaufende Ausnehmungen (20) aufweisen, mit denen sie von der Seite her auf jeweils eine Gruppe in einer - vornehmlich vertikalen - Ebene laufender Spannglieder (3) aufschiebbar sind, mit ihren Ausnehmungen (20) die Spannglie­ der (3) einseitig umfassen, diese in ihrer Sollage halten und die Schlitze (9) der Schottplatten (8) zwischen den Spanngliedern (3) gegen das Durchfließen von Beton beim Betonieren der Fertigteile (4) schließen, und indem die Kopfplatten (8) mit der Spannplatte (13) zu einer U-förmigen Einheit fest verbunden sind, die vor dem Betonieren der Fertigteile über die Abdichtplatten (19) stülpbar und nach dem Betonieren wieder aus dem noch frischen Beton aus­ ziehbar ist. With formwork for series prefabricated parts made of prestressed concrete, - in front convenient for turnouts to be manufactured one after the other in the fitted bed sleepers, made up of two side parts with in between fitted bottom plate and shelves that match the length of the Limit individual elements, all parts of the parking device designed so that they can be inserted into the formwork from above and can be removed from the formwork (2) after concreting. This is achieved by the seals (19) which are between the Bulkhead plates (8) are fitted, longitudinal recesses (20) have, with which they from the side to a group tendons running in a - mainly vertical - plane (3) can be pushed on, with their recesses (20) the tensioning bell which (3) embrace on one side, hold it in its target position and the Slots (9) of the bulkhead plates (8) between the tendons (3) against the flow of concrete when concreting the precast elements (4) close and by the head plates (8) with the clamping plate (13) are firmly connected to a U-shaped unit, which before Concrete of the precast elements can be put over the sealing plates (19) and after concreting again from the still fresh concrete is draggable.
