Description

Die Erfindung betrifft eine Schalung für Serienfertigteile aus Stahlbeton, wie sie gattungsmäßig im Oberbegriff des Anspruchs 1 beschrieben ist. Derartige Schalungen sind bekannt aus der DE-OS 29 48 303 und einer Veröffentlichung in der Zeitschrift "Die Bundesbahn", Heft 9/1982.The invention relates to a formwork for prefabricated parts made of reinforced concrete, as generically described in the preamble of claim 1. Such formwork is known from DE-OS 29 48 303 and a publication in the magazine "Die Bundesbahn", issue 9/1982.

Bei beiden bekannten Schalungskonstruktionen werden die Schwellen hintereinander ohne Abstellungen zwischen den einzelnen Schwellen in einem Stück betoniert. Das bedeutet, daß alle in einem Spannbett betonierten Schwellen in einem Stück ausgehoben und danach gedreht und getrennt werden müssen. Bei beiden Verfahren stehen die Einbauteile in der Schalung und die Vorrichtungen zum Ausheben der Fertigteile aus der bei der Fertigung obenliegenden Fläche und damit über den oberen Rand der Seitenteile der Schalung heraus. Da bei Schwellen die obenliegende Fläche des Fertigteils im Gebrauchszustand nach unten zu liegen kommt, müssen Schwellen für die endgültige Lagerung gedreht werden. Aus der Oberfläche herausstehende Teile müssen bei der Zwischenlagerung entfernt werden. Die Zwischenlagerung erfordert zusätzlichen Arbeitsaufwand und damit zusätzliche Kosten. Das Herausziehen der Einbauteile über den Rand der Seitenschalung macht außerdem das Abziehen der Schalung über die Ränder der Seitenelemente und die Anwendung von Rüttelbohlen zur Verdichtung des Betons unmöglich.In both known formwork constructions, the sleepers are concreted in one piece, one after the other, without stops between the individual sleepers. This means that all sleepers concreted in a fitted bed must be excavated in one piece and then turned and separated. In both methods, the built-in parts in the formwork and the devices for lifting the finished parts protrude from the surface at the top during production and thus above the upper edge of the side parts of the formwork. Since the top surface of the prefabricated part comes to lie down in sleepers in sleepers, sleepers must be turned for final storage. Parts protruding from the surface must be removed during intermediate storage. Interim storage requires additional work and thus additional costs. Pulling out the built-in parts over the edge of the side formwork also means pulling out the formwork over the edges of the side elements and the use of vibrating planks to compact the concrete is impossible.

Aufgabe der Erfindung war es, die vorgenannten Mängel zu beseitigen und eine Schalung zu entwickeln, bei der jedes Fertigteil einzeln aushebbar, drehbar und ohne Zwischenabsetzen endlagerbar ist.The object of the invention was to eliminate the above-mentioned shortcomings and to develop a formwork in which each finished part can be individually lifted, rotated and disposed of without intermediate repositioning.

Die Aufgabe wird durch ein Abstellelement gelöst, wie es im kennzeichnenden Teil des Anspruchs 1 beschrieben ist.The object is achieved by a storage element, as described in the characterizing part of claim 1.

Durch die zwischen die Seitenelemente der Schalung versenkte Konstruktion der Abstellvorrichtung können die Fertigteile über die Ränder der Seitenschalung abgezogen und gerüttelt werden. Durch Anordnung zweier entgegengesetzt angeordneter Kopfplatten zur Abstellung zwischen hintereinanderliegenden Fertigteilen und durch Anordnung von Zapfen auf den Kopfplatten, etwa in Schwerachse der Fertigteile, zumAusheben können die Fertigteile nach dem Erhärten getrennt einzeln aus der Schalung gehoben, gedreht und endgelagert werden, ohne daß eine Zwischenlagerung erforderlich wird.Due to the construction of the parking device, which is recessed between the side elements of the formwork, the finished parts can be pulled off and shaken over the edges of the side formwork. By arranging two oppositely arranged head plates to be placed between successive prefabricated parts and by arranging pegs on the head plates, for example in the axis of gravity of the finished parts, for lifting out, the finished parts can be separately lifted from the formwork after rotation, rotated and finally stored without intermediate storage being necessary becomes.

In Ausgestaltung der Erfindung ist in Anspruch 2 eine Variante zum Abstellelement nach Anspruch 1 beschrieben, bei dem der Abstand der Kopfplatten unabhängig von der Bodenplatte fixierbar ist. Dadurch wird erreicht, daß die Fertigteile beim Entspannen auf der Bodenplatte gleiten können. Ein Mitnehmen der Bodenplatten durch das Fertigteil infolge Verkürzung der frei liegenden Längen der Spanndrähte im Bereich der Abstellelemente beim Entspannen und ein erneutes Ausrichten der Bodenplatten für einen erneuten Betonvorgang wird dadurch vermieden.In an embodiment of the invention, a variant of the storage element according to claim 1 is described in claim 2, in which the distance between the head plates can be fixed independently of the base plate. This ensures that the finished parts can slide on the base plate when relaxing. Taking the floor panels with you the finished part due to the shortening of the exposed lengths of the tension wires in the area of the storage elements when relaxing and a new alignment of the base plates for a new concrete process is avoided.

An ihrem oberen Rand 19 werden sie von der auf Konsolen 20 aufliegenden Spannplatte 21 mit Hilfe der im Niederhalter 26 geführten Spannschraube 30 und der Klemmvorrichtung 27 an die Bodenplatten 5 angepreßt. Die Spannplatte 21 hält die Kopfplatten 17 oben auf Abstand. Beim Ausführungsbeispiel nach Fig. 4 drücken die am Niederhalter 26 angebrachten keilartig wirkenden Anschläge 23 auf Gegenanschläge 22 der Kopfplatten 17 und halten, indem sie mittels der am unteren Rand 18 der Kopfplatten 17 angeordneten Nasen 31 die Bodenplatten 5/n, 5/n + 1 auf Abstand.The storage element 6 includes with the head plates 17 the head formwork of two adjacent prefabricated parts 2 / n, 2 / n + 1 in the fitted bed 1. The head plates 17 sit on their lower edge 18 on the base plates 5 / n, 5 / n + 1. At their upper edge 19 they are supported by the clamping plate 21 resting on brackets 20 with the help of the clamping screw 30 guided in the hold-down device 26 and the clamping device 27 pressed against the base plates 5. The clamping plate 21 keeps the top plates 17 at a distance above. In the embodiment according to FIG. 4, the wedge-like stops 23 attached to the hold-down device 26 press against counter-stops 22 of the head plates 17 and hold them by means of the lugs 31 arranged on the lower edge 18 of the head plates 17, the base plates 5 / n, 5 / n + 1 at a distance.

Etwa mittig auf den Kopfplatten 17 sind Zapfen 25 angeordnet, an denen die Fertigteile 2 mit Hilfe geeigneter Voreispielsweise Kappen 332 richtungen einer Hubvorrichtung 32 aus dem Spannbett 1 aushebbar und drehbar sind.Pins 25 are arranged approximately in the middle on the head plates 17, on which the finished parts 2 can be lifted and rotated from the clamping bed 1 with the aid of suitable pre-example caps 332 directions of a lifting device 32.

Sämtliche in das Spannbett 1 einsetzbaren Einbauteile 9, 17, 21, 30 sind in ihrer Erstreckung nach oben so bemessen, daß sie nicht über den Rand der Seitenelemente 4 hinausstehen.All of the built-in parts 9, 17, 21, 30 which can be inserted into the fitted bed 1 are dimensioned in such a way that they do not protrude beyond the edge of the side elements 4.
