gießenden Betonteilenpoured concrete parts
Die Erfindung betrifft eine ein- oder mehrteilige Vorrichtung zum Einschalen oder Abschalen von zu gießenden Betonteilen, die mit wenigstens einer plattenförmigen Abdeckung ausgestattet sind.The invention relates to a one- or multi-part device for formwork or formwork removal of concrete parts to be cast, which are equipped with at least one plate-shaped cover.
' Die in Frage kommende Vorrichtung ist in den verschiedensten Ausführungen bekannt. Die jeweilige Ausführung richtet sich nach der Form des zu gießenden Betonteiles. ' The device in question is known in a wide variety of designs. The particular design depends on the shape of the concrete part to be cast.
Besonders wird die Vorrichtung als Fundamentschalungsvorrichtung eingesetzt. Einteilige Vorrichtungen haben sich zwar bewährt, sind jedoch mit dem Nachteil behaftet, daß sie ein großes Transportvolumen aufweisen und daß am Einbauort die Bewehrung schlecht zugänglich ist. Es sind deshalb zweiteilige Vorrichtungen bekannt, wobei die einzelnen Schalungsteile platzsparend gestapelt werden können.The device is used in particular as a foundation formwork device. One-piece devices have proven themselves, but have the disadvantage that they require a large transport volume and that the reinforcement is difficult to access at the installation site. Two-piece devices are therefore known, whereby the individual formwork parts can be stacked to save space.
Bei diesen Ausführungen muß jedoch sichergestellt sein, daß sie beim Betonieren formstabil sind.However, with these designs it must be ensured that they are dimensionally stable when concreting.

Die Anzahl der plattenförmigen Abdeckungen richtet sich auch nach der Form des zu gießenden Betonteiles. Bei Fundamenten sind die Vorrichtungen nach unten offen, da sie üblicherweise auf eine sogenannte Sauberkeitsschicht gestellt werden. Die seitlichen Bereiche sind dann durch diese Abdeckungen verschlossen.The number of plate-shaped covers also depends on the shape of the concrete part to be poured. In the case of foundations, the devices are open at the bottom, as they are usually placed on a so-called blind layer. The side areas are then closed off by these covers.
Jede plattenförmige Abdeckung wird in bevorzugten Ausführungen an einer geformten Baustahlgewebematte festgelegt. Bei den bisher bekannten Ausführungen besteht jede plattenförmige Abdeckung aus einem Blech, einem Streckmetall oder ähnlichen Materialien. Diese Materialien sind relativ teuer und da sie aus Stahl gefertigt sind, ist das Gewicht entsprechend hoch.In preferred designs, each plate-shaped cover is attached to a shaped steel mesh mat. In the designs known to date, each plate-shaped cover consists of a sheet metal, expanded metal or similar materials. These materials are relatively expensive and, since they are made of steel, the weight is correspondingly high.
Der Erfindung liegt die Aufgabe zugrunde, eine ein- oder mehrteilige Vorrichtung der eingangs näher beschriebenen Art so zu gestalten, daß sie kostengünstig herstellbar ist, daß die plattenförmigen Abdeckungen einfach zu formen sind und daß das Gewicht so gering wie möglich ist.The invention is based on the object of designing a one- or multi-part device of the type described in more detail above in such a way that it can be produced inexpensively, that the plate-shaped covers are easy to form and that the weight is as low as possible.
Die gestellte Aufgabe wird gelöst, indem jede plattenförmige Abdeckung aus einem zellulosehaltigen Material besteht. Das zellulosehaltige Material läßt sich einfach verformen. Außerdem ist das Gewicht äußerst gering.The task is solved by making each plate-shaped cover out of a cellulose-containing material. The cellulose-containing material is easy to shape. In addition, the weight is extremely low.
Es hat sich verblüffend herausgestellt, daß derartige Materialien nicht nur dem Betondruck standhalten, sondern daß sie auch gegen Feuchtigkeit ausreichend beständig sind.
25It has been astonishingly found that such materials not only withstand the pressure of concrete, but are also sufficiently resistant to moisture.
25
Als zellulosehaltiges Material wird bevorzugt Karton verwendet. Besonders geeignet ist jedoch Wellkarton, der höher belastbar ist als ein einfacher Karton.Cardboard is the preferred material containing cellulose. However, corrugated cardboard is particularly suitable as it can bear more loads than a simple cardboard box.
Um die Resistenz gegen Feuchtigkeit zu erhöhen, ist in weiterer Ausgestaltung vorgesehen, daß jede plattenförmige Abdeckung zumindest an einer Seite mit einer feuchtigkeitsabweisenden Beschichtung versehen ist. Diese Beschichtung liegt dann an der Betonseite.In order to increase resistance to moisture, a further development provides that each plate-shaped cover is provided with a moisture-repellent coating on at least one side. This coating is then on the concrete side.

In bevorzugter Ausführung besteht diese feuchtigkeitsabweisende Beschiehtung aus Bitumen.In the preferred version, this moisture-repellent coating consists of bitumen.
Es ist allgemein bekannt, daß Karton und auch Wellkarton nicht extrem hoch belastbar sind. Es ist deshalb vorgesehen, daß jede aus Karton oder Wellkarton bestehende plattenformige Abdeckung an einem Stützkörper festgelegt ist. Dieser Stützkörper besteht zweckmäßigerweise aus einer Baustahlgewebematte. Die von den Stäben begrenzten Felder sind relativ klein, so daß der von dem flüssigen Beton ausgehende Druck über eine entsprechend hohe Anzahl von Stäben abgetragen wird, wodurch die Gefahr des Brechens des Kartons oder des Wellkartons ausge-It is generally known that cardboard and corrugated cardboard cannot bear extremely high loads. It is therefore intended that each panel-shaped cover made of cardboard or corrugated cardboard is attached to a support body. This support body is preferably made of a steel mesh mat. The areas delimited by the rods are relatively small, so that the pressure emanating from the liquid concrete is carried off by a correspondingly high number of rods, which eliminates the risk of the cardboard or corrugated cardboard breaking.
. schlossen werden kann.. can be closed.
Darüber hinaus ist eine Baustahlgewebeplatte relativ preiswert zu beziehen und die Formung verhältnismäßig einfach. Die Verwendung von Karton oder Wellkarton bietet außerdem noch den Vorteil, daß jede plattenformige Abdeckung mittels Klammern an den Stäben der Baustahlgewebematte festgelegt werden kann. Dieses Klammern erfolgt mit einfachen Werkzeugen.In addition, a steel mesh panel is relatively inexpensive to purchase and relatively easy to shape. The use of cardboard or corrugated cardboard also offers the advantage that each panel-shaped cover can be secured to the bars of the steel mesh mat using clamps. This clamping is done using simple tools.
Anhand der beiliegenden Zeichnungen wird die Erfindung noch näher erläutert. 20The invention is explained in more detail with reference to the accompanying drawings. 20

Die Baustahlgewebematte beinhaltet sich kreuzende Stäbe 11 und 12. Im Gegensatz zu der dargestellten Ausführung könnte die Vorrichtung auch U-förmig ausgebildet sein, wenn beispielsweise ein Streifenfundament betoniert werden soll.The structural steel mesh mat contains intersecting bars 11 and 12. In contrast to the embodiment shown, the device could also be U-shaped if, for example, a strip foundation is to be concreted.
An den aufrecht stehenden Stäben 11 ist eine plattenförmige Abdeckung 13 mittel Klammern befestigt, die aus Wellkarton besteht. Sofern die Vorrichtung U-förmig ist, würde noch eine zweite plattenförmige Abdeckung vorgesehen sein.A plate-shaped cover 13 made of corrugated cardboard is attached to the upright rods 11 by means of clamps. If the device is U-shaped, a second plate-shaped cover would be provided.
Die Figur 2 zeigt, daß die plattenförmige Abdeckung 13 mit einer wasserabweisenden Beschichtung aus Bitumen versehen ist. Diese Schicht liegt an der dem Beton zugewandten Seite und stützt die plattenförmige Abdeckung gegen das Eindringen von Feuchtigkeit.Figure 2 shows that the plate-shaped cover 13 is provided with a water-repellent coating of bitumen. This layer is on the side facing the concrete and supports the plate-shaped cover against the penetration of moisture.
Die Figur 3 zeigt die Vorrichtung 10 als Rand- oder Eckschalung für eine Sohlplatte. Die Vorrichtung ist nicht nur mit der plattenförmigen Abdeckung 13 ausgestattet, sondern mit einer im Winkel dazu stehenden weiteren Abdeckung 14, die ebenfalls aus Karton oder Wellkarton gefertigt ist.Figure 3 shows the device 10 as edge or corner formwork for a base plate. The device is not only equipped with the plate-shaped cover 13, but also with a further cover 14 at an angle to it, which is also made of cardboard or corrugated cardboard.
Auch diese zusätzliche Abdeckung 14 könnte mit einer feuchtigkeitsabweisenden Beschichtung aus Bitumen versehen sein.This additional cover 14 could also be provided with a moisture-repellent coating made of bitumen.
Gemäß den Darstellungen nach den Figuren 1 und 2 sind die sich kreuzenden Stäbe 11 und 12 in gleichen Abständen zueinander angeordnet. Es sei noch daraufhingewiesen, daß sich diese Abstände auch ändern können.
25According to the representations in Figures 1 and 2, the crossing bars 11 and 12 are arranged at equal distances from each other. It should also be noted that these distances can also change.
