Abstract

One wall at least (12) is inclined, including with the opposite one an angle open towards the top. A combined vertical and horizontal movement can be imparted to this wall during knocking-out, typically by a control slide. The wall can be movable horizontally inside the mould (3), after which the latter's walls (11, 12) are moved in the vertical direction by lifting the entire mould. An inclined control face (13) can be provided on a thrust plate (9), the wall sliding on it during lifting and simultaneously moving in the horizontal direction.

Description

Die Erfindung betrifft eine Form zur Herstellung von Formsteinen, insbesondere aus fließfähigem Beton mit einem oder mehreren Formnestern, die durch vertikale Formwände begrenzt sind, wobei jeweils mindestens eine Formwand schräg verläuft und mit der gegenüberliegenden Formwand einen nach oben geöffneten Winkel einschließt.The invention relates to a mold for the production of molded blocks, in particular from flowable concrete with one or more mold nests, which are delimited by vertical mold walls, wherein at least one mold wall runs obliquely and includes an upwardly open angle with the opposite mold wall.

Bei der Herstellung von Beton-Formsteinen in Formen mit geraden, vertikalen Seitenwänden wird in der Regel zum Entformen des fertigen Betonsteines die Form nach oben vom Betonstein abgezogen. Dabei bewegen sich die vertikalen Seitenwände der Form an den Außenseiten des Betonsteines entlang, so daß ein Glattstrich entsteht, der dem Betonstein ein gefälliges Aussehen verleiht und das Entstehen von Lunkern und Unebenheiten an den Außenseiten des Betonsteines beim Entformen verhindert. Mit diesem bekannten Herstellungsverfahren ist es jedoch nicht möglich, Formsteine mit einer zur Vertikalen geneigten Seitenwand, beispielsweise Treppenstufen, herzustellen.When producing concrete blocks in molds with straight, vertical side walls, the mold is usually subtracted from the concrete block to demould the finished concrete block. The vertical side walls of the mold move along the outside of the concrete block, so that a smooth line is created, which gives the concrete block a pleasing appearance and prevents the formation of voids and unevenness on the outside of the concrete block during demolding. With this known manufacturing method, however, it is not possible to produce shaped stones with a side wall inclined to the vertical, for example stair treads.

Ferner ist es bekannt, Betonformteile mit nach oben divergierenden Seitenwänden in Handkippformen oder maschinellen Kippformen herzustellen. Dabei wird die mit Beton gefüllte Form um 180° gedreht und das fertige Betonformteil auf einer Stahlunterlage abgesetzt. Eine gute Oberflächenbeschaffenheit wird dabei nur auf der Seite des Formteils erreicht, die auf der Stahlunterlage aufliegt. Außerdem ist dieses Verfahren aufwendig und für eine rationelle Fertigung nicht geeignet.Furthermore, it is known to produce molded concrete parts with upwardly diverging side walls in manual tilting molds or mechanical tilting molds. The mold filled with concrete is rotated by 180 ° and the finished concrete part is placed on a steel base. A good surface quality is only achieved on the side of the molded part that lies on the steel base. In addition, this process is complex and not suitable for efficient production.

Es ist auch bekannt, eine oder mehrere Seitenwände der Form beim Entformen des Betonteils in horizontaler Richtung zu verschieben. Dabei wird ebenfalls keine saubere Oberfläche erreicht, da sich der Beton auf der Seitenwand aufbaut und nicht glattgestrichen wird.It is also known to move one or more side walls of the mold in the horizontal direction when the concrete part is removed from the mold. A clean surface is also not achieved, since the concrete builds up on the side wall and is not smoothed out.

Der Erfindung liegt die Aufgabe zugrunde, eine Form der eingangs erwähnten Art zu schaffen, die bei Formsteinen mit mindestens einer schrägen Seitenwand eine exakte Formgebung und eine saubere, glatte Oberfläche des fertigen Formsteins bei rationeller Fertigung gewährleistet.The invention has for its object to provide a shape of the type mentioned, which ensures a precise shape and a clean, smooth surface of the finished stone with rational production in the case of shaped stones with at least one sloping side wall.

Gemäß der Erfindung wird die Aufgabe dadurch gelöst, daß die schrägen Formwände der Formnester einzeln oder gemeinsam zum Entformen des fertigen Formsteins in Richtung ihrer Schräge nach oben bewegbar sind.According to the invention, the object is achieved in that the oblique mold walls of the mold cavities can be moved upwards in the direction of their bevel individually or together for demolding the finished molded block.

Weitere wesentliche Merkmale der Erfindung sind den Patentansprüchen zu entnehmen.Further essential features of the invention can be found in the patent claims.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß infolge der beim Entformen in Richtung der gewünschten Schräge bewegbaren Formwand die Oberfläche des Formsteins glattgestrichen wird. Dadurch erhält die schräge Seitenwand des fertigen Formsteins in gleicher Weise wie die vertikalen Seitenwände, die beim Entformen durch vertikales Anheben der Form ebenfalls glattgestrichen werden, eine saubere und glatte Oberfläche. Außerdem wird dadurch eine Selbstreinigung der Formwände erreicht.The advantages achieved with the invention consist in particular in that, as a result of the mold wall which can be moved in the direction of the desired bevel during demolding, the surface of the molded block is smoothed out. This gives the sloping side wall of the finished molded block a clean and smooth surface in the same way as the vertical side walls, which are also smoothed out when the mold is removed by lifting the mold vertically. In addition, self-cleaning of the mold walls is achieved.

Auf einem Rütteltisch 1 einer Formmaschine 2 ist eine Form 3 mit mehreren Formnestern 4 unter Zwischenschaltung eines Unterlagebretts 5 angeordnet. Die Form 3 ist mit seitlichen Ansätzen 6 an vertikal beweglichen, durch nicht dargestellte Kolben-Zylinder-Einheiten antreibbaren Trägern 7 der Formmaschine 2 auswechselbar befestigt. Den Formnestern 4 sind in bekannter Weise vertikal bewegliche, durch eine Kolben-Zylinder-Einheit 8 angetriebene Druckplatten 9 zugeordnet, die auf den mit Betonmasse gefüllten Formnestern 4 aufliegen.A mold 3 with a plurality of mold nests 4 is arranged on a vibrating table 1 of a molding machine 2 with the interposition of a base board 5. The mold 3 is fastened in an exchangeable manner to the vertically movable supports 7 of the molding machine 2, which can be driven by piston-cylinder units (not shown). The mold nests 4 are assigned in a known manner vertically movable, driven by a piston-cylinder unit 8 pressure plates 9, which rest on the mold nests 4 filled with concrete mass.

Die Formnester 4 befinden sich in einem Formeinsatz 10, der mit der Form 3 durch eine lösbare Klemmverbindung fest verbunden ist (Fig. 3). Der Formeinsatz 10 weist im Ausführungsbeispiel drei Formnester 4 auf. Jedes Formnest 4 ist durch drei vertikale Formwände 11 und eine schräge, bewegliche Formwand 12 begrenzt, die mit der gegenüberliegenden Formwand 11 einen nach oben offenen Winkel einschließt. Wie aus Fig. 1 hervorgeht, ist die schräge Formwand 12 im Querschnitt trapezförmig mit einer schräg verlaufenden Innenfläche ausgeführt, die an einer schrägen Steuerfläche 13 der Druckplatte 9 anliegt. Dabei entspricht die Schräge der Steuerfläche 13 der Schräge der Formwand 12. Durch die schräge Formwand 12 erhält der fertige Formstein, beispielsweise eine Treppenstufe, die gewünschte Schräge an einer Seite.The mold cavities 4 are located in a mold insert 10 which is firmly connected to the mold 3 by a releasable clamping connection (FIG. 3). The mold insert 10 has three mold cavities 4 in the exemplary embodiment. Each mold cavity 4 is delimited by three vertical mold walls 11 and an inclined, movable mold wall 12, which encloses an upwardly open angle with the opposite mold wall 11. As is apparent from Fig. 1, is the oblique Molded wall 12 is trapezoidal in cross-section with an inclined inner surface which bears against an inclined control surface 13 of the pressure plate 9. The bevel of the control surface 13 corresponds to the bevel of the mold wall 12. The bevel mold wall 12 gives the finished molded block, for example a step, the desired bevel on one side.

Die drei schrägen Formwände 12 der drei Formnester 4 sind jeweils an einem Träger 14 befestigt, dessen Enden durch Öffnungen 15 in den Formwänden 11 nach außen geführt und mit je einer Kolbenstange 16 von seitlich an der Form 3 angeordneten, einfach wirkenden Hydraulikzylindern 17 verbunden sind (Fig. 3 und 5). Die Kolbenstange 16 ist von Distanzrohren 18 und Lagerbuchsen 19 umgeben, die mit einer Schraube 20 am Ende der Kolbenstange 16 gegeneinander festgespannt werden. Dabei wird jeweils die Lagerbuchse 19 zwischen Distanzrohr 18 und Träger 14, der von der Kolbenstange 16 durchsetzt ist, eingespannt (Fig. 5). Die Lagerbuchsen 19 sind in Lagern 21 verschiebbar gelagert, die an der Unterseite einer Grundplatte 22 befestigt sind (Fig. 4 und 6). Auf diese Weise wird eine innerhalb der Form 3 horizontal verfahrbare Einheit gebildet, die aus den drei schrägen Formwänden 12, den Trägern 14 und den Kolbenstangen 16 der in die Form 3 integrierten Hydraulikzylinder 17 besteht.The three inclined mold walls 12 of the three mold cavities 4 are each fastened to a carrier 14, the ends of which are guided outwards through openings 15 in the mold walls 11 and are each connected to a piston rod 16 of single-acting hydraulic cylinders 17 arranged laterally on the mold 3 ( 3 and 5). The piston rod 16 is surrounded by spacer tubes 18 and bearing bushes 19 which are clamped against one another with a screw 20 at the end of the piston rod 16. In this case, the bearing bush 19 is clamped between the spacer tube 18 and the carrier 14, which is penetrated by the piston rod 16 (FIG. 5). The bearing bushes 19 are slidably mounted in bearings 21 which are fastened to the underside of a base plate 22 (FIGS. 4 and 6). In this way, a horizontally movable unit is formed within the mold 3, which consists of the three inclined mold walls 12, the supports 14 and the piston rods 16 of the hydraulic cylinders 17 integrated in the mold 3.

Die Wirkungsweise der Erfindung ist wie folgt.The operation of the invention is as follows.

Die Formnester 4 werden zunächst mit Betonmasse gefüllt, gerüttelt und durch Absenken der Druckplatten 9 in die Stellung gemäß Fig. 1 verschlossen. Nach dem Füll- und Rüttelvorgang wird die Form 3 von den antreibbaren Trägern 7 zum Entformen der fertigen Formsteine in die Stellung gemäß Fig. 2 angehoben. Während der Vertikalbewegung der Form 3 nach oben gleitet die schräge Innenfläche der Formwand 12 an der Steuerfläche 13 der Druckplatte 9 entlang. Dabei entsteht eine Horizontalbewegung der Formwände 12, der Träger 14 und der Kolbenstangen 16, da die einfach wirkenden Hydraulikzylinder 17 drucklos sind und die Kolben gegen den Widerstand der abfließenden Hydraulikflüssigkeit zurückgedrängt werden. Somit ergibt sich eine kombinierte Vertikal-und Hozizontalbewegung, aufgrund deren die schrägen Formwände 12 in Richtung ihrer Schräge nach oben bewegt und dabei die entsprechend schräge Außenseite des Formsteins geformt und glattgestrichen wird. Nachdem die Stellung gemäß Fig. 2 erreicht ist, wird die Form 3 zusammen mit den Druckplatten 9 noch etwas weiter nach oben gefahren, so daß die fertigen Formsteine durch Ausfahren des Unterlagebretts 5 abtransportiert werden können.The mold cavities 4 are first filled with concrete, shaken and closed by lowering the pressure plates 9 into the position shown in FIG. 1. After the filling and shaking process, the mold 3 is raised by the drivable carriers 7 to demold the finished molded blocks into the position according to FIG. 2. During the vertical movement of the mold 3 upwards, the inclined inner surface of the mold wall 12 slides along the control surface 13 of the pressure plate 9. This creates a horizontal movement of the mold walls 12, the carrier 14 and the piston rods 16, since the single-acting hydraulic cylinders 17 are depressurized and the pistons are pushed back against the resistance of the hydraulic fluid flowing away. This results in a combined vertical and horizontal movement, on the basis of which the inclined mold walls 12 are moved upwards in the direction of their incline and the correspondingly inclined outside of the molded block is shaped and smoothed out. After the position according to FIG. 2 has been reached, the mold 3 is moved a little further upwards together with the pressure plates 9, so that the finished molded blocks can be removed by extending the support board 5.

Anstelle der Steuerfläche 13 der Druckplatte 9 kann auch eine außerhalb des Formnestes 4 befindliche Kulissensteuerung verwendet werden, die eine schräg nach oben gerichtete Bewegung der Seitenwand 12 durch eine simulierte Bewegung bewirkt.Instead of the control surface 13 of the pressure plate 9, a link control located outside the mold cavity 4 can also be used, which controls an obliquely upward direction Movement of the side wall 12 caused by a simulated movement.

Ferner ist es möglich, anstelle der einfach wirkenden Hydraulikzylinder 17 doppelt wirkende zu verwenden und diese beispielsweise durch eine Programmsteuerung mit den die Vertikalbewegung der Form 3 bewirkenden Kolben-Zylinder-Einheiten so zu kombinieren und abzustimmen, daß die gewünschte Schräglaufbewegung der Formwände 12 erreicht wird.It is also possible to use double-acting hydraulic cylinders 17 instead of the single-acting ones, and to combine and coordinate them, for example, by program control with the piston-cylinder units causing the vertical movement of the mold 3, so that the desired skew movement of the mold walls 12 is achieved.

Mit Hilfe einer derartigen Programmsteuerung oder auch mit der Kulissensteuerung lassen sich Formsteine mit geometrisch unterschiedlich geformten Seitenwänden, beispielsweise auch gekrümmte Seitenwände, mit den gleichen Vorteilen herstellen.With the aid of such a program control or also with the backdrop control, shaped blocks with geometrically differently shaped side walls, for example also curved side walls, can be produced with the same advantages.
