Abstract

In shutterings for series-produced prefabricated concrete parts, for example for switch sleepers, the metal base plate (3) of the shuttering simultaneously serves as template for the positions of the installation parts. It is usually newly produced for each series production of prefabricated parts. In the case of small series with different positions of the installation part, it is economical to use a metal base plate (3) a number of times. This takes place by coating the metal base plate (3) with a covering (6), as a result of which the bores (7) of previous usages are closed. In accordance with markings on the covering (6), the bores (9) for the next usage are produced through the covering (6). <IMAGE>

Description

Die Erfindung betrifft ein Verfahren, wie es im Oberbegriff des Anspruchs 1 beschrieben ist.The invention relates to a method as it is in the preamble of Claim 1 is described.

Schalungen für Serienfertigteile aus Beton werden in der Regel wegen der hohen Fertigungszahlen sehr stabil und aufwendig hergestellt. Dies trifft im besonderen Maße für im Spannbett hintereinander her­ gestellte Weichenschwellen zu. Bei diesen werden zusätzlich sehr hohe Anforderungen an einen maßgenauen Einbau von Einbauteilen gestellt. Die Einbauteile werden deshalb in Bohrungen in der Schalung fixiert.Formwork for series production parts made of concrete are usually due the high production numbers very stable and complex manufactured. This is particularly true for one after the other in the fitted bed provided turnout sleepers. In addition, these are very high requirements for a dimensionally accurate installation of built-in parts posed. The built-in parts are therefore in holes in the Fixed formwork.

Bei Schwellen liegen die Einbauteile, Dübel oder Rohrhülsen für die Schwellenverankerungsschrauben auf der Oberseite der Schwelle. Die Oberseite der Schwelle liegt in der Schalung auf dem Schalungs­ boden. Dieser dient somit als Schablone für den Einbau der Einbau­ teile.The built-in parts, dowels or pipe sleeves are for sleepers Threshold anchor bolts on the top of the threshold. The The top of the threshold lies in the formwork on the formwork ground. This serves as a template for the installation of the installation parts.

Bei großen Serien beeinflussen die für jeden Schwellentyp herzu­ stellenden Schablonen die Kosten für die Einzelschwelle nur wenig. Bei geringen Herstellungszahlen können die Kosten für diese als Schablonen für die Einbauteile dienenden Bodenplatten die Wirt­ schaftlichkeit der Fertigung in Frage stellen.In large series, this affects every type of threshold the cost of the individual threshold is low. With low manufacturing numbers, the cost of this can be as Templates for the mounting plates serving the host question the economics of production.

Eine Schalung für Weichenschwellen aus Beton ist aus der DE 34 40 247 bekannt. Diese Schalung weist ein stählernes Bodenblech auf, das paßgenau zwischen Seitenteilen eingelassen ist. Das Anfertigen mit Bohrungen an anderer Stelle versehener neuer Bodenbleche und deren Einbau sind aufwendig.
A formwork for switch sleepers made of concrete is known from DE 34 40 247. This formwork has a steel floor panel, which is embedded precisely between side parts. The production of new floor panels with holes drilled elsewhere and their installation are complex.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu ent­ wickeln, nach dem ein Bodenblech bei kleinen Serien für Fertigteile mit unterschiedlicher Anordnung der Einbauteile wiederholt verwend­ bar ist.The object of the invention is to develop a method wrap after a floor panel in small series for finished parts repeatedly used with different arrangement of the built-in parts is cash.

Die Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Maßnahmen gelöst. Eine Ausgestaltung des Verfahrens ist im Unteranspruch 2 angegeben.The task is defined in the characterizing part of the claim 1 specified measures solved. An embodiment of the method is specified in dependent claim 2.

Die Erfindung betrifft ferner gemäß den Ansprüchen 3 bis 6 Abdeckungen zur Durchführung des er­ findungsgemäßen Verfahrens.The invention further relates to the claims 3 to 6 covers to carry out the he inventive method.

Die erfindungsgemäße dünne Abdeckung aus einem Material, das auf­ grund der gewählten Dicke und Festigkeit die bereits im Bodenblech enthaltenen Bohrungen unter Betonierdruck schadlos überspannen kann, wird für jeden neuen Fertigteiltyp neu angefertigt. Sie kann ohne großen Aufwand hergestellt werden. Mit Computerhilfe können die Markierungen für die Positionen der Einbauteile auf ihr ein­ gezeichnet werden, so daß sie bereits für die Bohrungen als Scha­ blone dienen kann. Die Anfertigung einer solchen Abdeckung aus dünnem Blech, Kunststoff oder synthetischem Papier ist erheblich kostengünstiger als eine Neuanfertigung des stählernen Bodenblechs für die Schalung.The thin cover according to the invention made of a material based on due to the selected thickness and strength, that already in the floor panel Cover the holes contained under concrete pressure without damage can be made for each new type of precast. she can can be produced with little effort. With computer help you can the markings for the positions of the installation parts on it are drawn so that they are already for the holes as Scha blone can serve. The preparation of such a cover thin sheet metal, plastic or synthetic paper is significant less expensive than a new production of the steel floor plate for the formwork.

Die Erfindung wird durch die Fig. 1 bis 3 erläutert. Es zeigtThe invention is illustrated by FIGS. 1 to 3. It shows

Fig. 1 ein Spannbett mit hergestellten Serienfertigteilen im Schnitt, Fig. 1 a fitted with established series finished parts in section,

Fig. 2 eine auf das Bodenblech aufgeklebte Abdeckung in der Aufsicht, Fig. 2 is a glued onto the bottom cover plate in plan view,

Fig. 3 einen vertikalen Schnitt durch Abdeckung und Bodenplatte. Fig. 3 shows a vertical section through the cover and base plate.

In einer Fertigungsanlage 1 für Betonfertigteile im Spannbett werden Serienfertigteile 2 - im Beispiel Weichenschwellen - zwischen Seitenschalungen auf Bodenblechen 3 hergestellt. In den Boden­ blechen 3 fixieren Bohrungen 4 die Position von Einbauteilen 5 in den Fertigteilen 2. Für jede weitere Verwendung des Bodenblechs 3 wird eine Abdeckung 6 angefertigt, auf der die zugehörigen neuen Positionen der Einbauteile markiert sind. Diese beispielsweise aufgeklebte Abdeckung 6 überdeckt die Bohrungen 7 des Bodenblechs 3 aus vorausgegangenen Verwendungen. An den vorher auf der Ab­ deckung 6 aufgebrachten Markierungen 8 werden durch die Abdec­ kung 6 hindurch deckungsgleich im Bodenblech 3 die Bohrungen 9 für die Positionen der Einbauteile der neuen Verwendung hergestellt.In a production plant 1 for precast concrete parts in the fitted bed, series prefabricated parts 2 - in the example switch sleepers - are produced between side formwork on floor panels 3 . In the bottom plates 3, bores 4 fix the position of built-in parts 5 in the finished parts 2 . For each further use of the floor panel 3 , a cover 6 is made on which the associated new positions of the built-in parts are marked. This cover 6 , for example glued on, covers the bores 7 of the floor panel 3 from previous uses. At the markings 8 previously applied to the cover 6 , the holes 9 for the positions of the built-in parts of the new use are made congruently through the cover 6 through the cover plate 3 .
