Abstract

The method involves automatically demolishing a molding body (5) after a pre-determined setting time of concrete (3), where the molding body is formed of frozen fluid. The molding body is blocked by a pin that is arranged on an upper side of a core base (2). The molding body is provided with a flexible protection sleeve. The molding body is sectioned or milled out from a frozen block, and blocked on the core base using magnets, where a trapping funnel (6) for a dew medium is arranged under the core base. Air supply line (7) and a suction line (8) are attached to the trapping funnel. An independent claim is also included for a device for manufacturing profiled concrete or steel concrete parts.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von profilierten Beton- und Stahlbetonteilen unter Verwendung von Schalungskörpern.The invention relates to a method and an apparatus for producing profiled concrete and reinforced concrete parts using formwork bodies.

Im Beton- und Stahlbetonbau gibt es eine Vielzahl von Geometrien, deren Herstellung aufwendig und kompliziert ist. So ist beispielsweise das Einschalen und auch das Ausschalen von Hinterschneidungen, Gerinnen, Ausnehmungen oder Hohlräumen u. ä. Geometrien mit Zusatzleistungen verbunden. Nicht selten wird hierbei nach völliger Aushärtung des Betons der Schalungskörper herausgeschlagen.In concrete and reinforced concrete construction, there are a variety of geometries, the production of which is complicated and complicated. For example, the shelling and the stripping of undercuts, channels, recesses or cavities u. ä. Geometries associated with additional services. Not infrequently, the formwork body is knocked out after complete hardening of the concrete.

Der Erfindung liegt die Aufgabe zugrunde, die Herstellung von profilierten Betonteilen wirtschaftlicher zu gestalten, wobei insbesondere das Entfernen der Schalungskörper entfällt.The invention has for its object to make the production of profiled concrete parts more economical, in particular, the removal of the formwork body deleted.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass sich die Schalungskörper nach einer vorbestimmten Abbindezeit des Betons selbst zerstören. Bei einer bevorzugten Ausführung ist der Schalungskörper aus gefrorener Flüssigkeit gebildet. Vorteilhafterweise wird der Schalungskörper mit einer flexiblen Schutzhülle versehen. Nach einem Merkmal der Erfindung wird der Schalungskörper aus einem gefrorenen Block ausgeschnitten oder ausgefräst.This object is achieved in that destroy the formwork body after a predetermined setting time of the concrete itself. In a preferred embodiment, the formwork body is formed of frozen liquid. Advantageously, the formwork body is provided with a flexible protective cover. According to a feature of the invention, the formwork body is cut or milled out of a frozen block.

Eine Vorrichtung zur Herstellung von profilierten Beton- und Stahlbetonteilen unter Verwendung von Schalungskörpern, insbesondere zur Herstellung von Schachtunterteilen, ist dadurch gekennzeichnet, dass der Schalungskörper aus gefrorener Flüssigkeit auf einem Kernboden lagert, wobei der Kernboden Durchbrechungen und obere abstehende Stifte aufweisen kann. Die Stifte dienen zum Eindrücken in den Schalungskörper. Bei einer Variante ist der Schalungskörper auf dem Kernboden durch Magnete arretiert. Es besteht die Möglichkeit, unterhalb des Kernbodens einen Auffangtrichter für das Taumedium anzuordnen, wobei in Ausgestaltung der Erfindung dem Auffangtrichter mindestens je eine Luftzuführ- und Absaugleitung zugeordnet sind.A device for the production of profiled concrete and reinforced concrete parts using formwork bodies, in particular for the production of manhole bases, is characterized in that the formwork body of frozen liquid superimposed on a core bottom, the core bottom can have openings and upper protruding pins. The pins serve to push into the formwork body. In a variant of the formwork body is locked on the core bottom by magnets. It is possible to arrange a collecting funnel for the Taumedium below the core bottom, wherein in an embodiment of the invention the collecting funnel at least one air supply and suction are assigned.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben. Es zeigen:An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it:

1 einen Vertikalschnitt durch ein Schachtunterteil gemäß Linie A-B der 2 und 1 a vertical section through a manhole base according to line AB of 2 and

2 eine Draufsicht auf ein Schachtunterteil. 2 a plan view of a manhole base.

Der aus gefrorener Flüssigkeit bestehende Schalungskörper 5 lagert auf einem Kernboden 2, der zur Abführung von Flüssigkeit Durchbrechungen 9 aufweist. Der Schalungskörper 5 wird durch auf der Oberseite des Kernbodens 2 angeordnete abstehende Stifte arretiert. Mit 1 ist der Außenmantel der Schalung für den Beton 3 und mit 4 das Rohanschlusselement bezeichnet.The formwork body consisting of frozen liquid 5 stored on a core soil 2 , which is responsible for the discharge of fluid breakthroughs 9 having. The formwork body 5 gets through on top of the core floor 2 arranged protruding pins locked. With 1 is the outer shell of the formwork for the concrete 3 and with 4 denotes the Rohanschlusselement.

Unterhalb des Schalungskörpers 5 ist ein Fangtrichter 6 für das Taumedium angeordnet, dem mindestens je eine Luftzuführleitung 7 und eine Absaugleitung 8 zugeordnet sind. Über die Luftzuführleitung 7 kann ein Vakuum erzeugt werden, durch welches nach Abbinden des aufgebrachten Betons 3' die flexible Schutzhülle des dann bereits nicht mehr existenten Schalungskörpers 5 entfernt werden kann.Below the formwork body 5 is a drogue 6 arranged for the Taumedium, the at least one air supply line 7 and a suction line 8th assigned. About the air supply line 7 A vacuum can be generated by which, after setting the applied concrete 3 ' the flexible protective cover of the already no longer existing formwork body 5 can be removed.
