Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Betonplatten mit einer ortsfesten Betonierstation, mit durch die Betonierstation fahrbaren Paletten, mit an der Betonierstation vorgesehenen Stirn- und Seitenabstellungen, die auf die jeweils in die Betonierstation eingefahrene Palette zur Bildung einer zusammengesetzten Schalung aufsetzbar bzw. von dieser wieder entfernbar sind, und mit Schubvorrichtungen, an denen die Seitenabstellungen befestigt sind.The invention relates to a device for producing concrete slabs with a stationary concreting station, with pallets that can be moved through the concreting station, with end and side supports provided at the concreting station, which can be placed on or from the pallet inserted into the concreting station to form a composite formwork are removable, and with pushers to which the side shelves are attached.

Eine derartige Vorrichtung ist bekannt (Zeitschrift "Betonwerk und Fertigteil-Technik", Oktober 1980, Seiten 633 bis 638). Bei der bekannten Vorrichtung werden die Seitenabstellungen hydraulisch auf die Palette aufgesetzt bzw. von dieser hochgezogen. Die Stirnabstellungen dienen zur Aufnahme der Kernrohre und sind mit entsprechenden Löchern zum Hindurchführen der Kernrohre versehen. Für verschieden dicke Betonplatten sollen die Seitenabschalungen ausgewechselt werden.Such a device is known (magazine "Betonwerk und Fertigteil-Technik", October 1980, pages 633 to 638). In the known device, the side racks are placed hydraulically on the pallet or pulled up by the latter. The end stops serve to receive the core tubes and are provided with corresponding holes for the core tubes to pass through. The side formwork should be replaced for different thickness concrete slabs.

Schon seit langem ist es bekannt, Betonfertigteile fließbandmäßig herzustellen. Bei großen, langen Betonfertigteilen wurden Seitenwände der Schalung verstellbar und der auf einem Formwagen aufliegende Formboden von diesem lösbar ausgebildet (AT-B-206 804).It has long been known to manufacture precast concrete parts on an assembly line. In the case of large, long precast concrete elements, the side walls of the formwork were adjustable and the mold floor resting on a molding carriage was designed to be detachable from it (AT-B-206 804).

Bei plattenförmigen Betonfertigteilen sind die Stirn- und Seitenabstellungen als gesamter Rahmen um eine horizontale Welle verschwenkbar zur Abnahme des Betonfertigteils von einer ortsfesten Basis und Ablage auf eine andere Basis oder eine Palette. Stirn- und Seitenabstellungen sind für geneigte Seitenränder verstellbar, damit aus den Betonfertigteilen Silokonstruktion oder dergleichen unterschiedlicher Durchmesser gebaut werden können (US-A-14 84 855).In the case of prefabricated concrete slabs, the front and side shelves can be pivoted as a whole frame around a horizontal shaft in order to remove the precast concrete element from a fixed base and place it on another base or pallet. Front and side supports are adjustable for inclined side edges, so that silo construction or the like of different diameters can be built from the precast concrete parts (US-A-14 84 855).

Bei den bekannten Vorrichtungen ist erheblicher Aufwand erforderlich, wenn Betonfertigteile anderer Größe, d.h. anderer Abmessungen, hergestellt werden sollen. Insbesondere ist Montageaufwand erforderlich und sind sogar Teile auszutauschen.In the known devices, considerable effort is required if precast concrete parts of a different size, i.e. other dimensions to be produced. In particular, assembly effort is required and even parts have to be replaced.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art so zu gestalten, daß mit ihr ohne Montageaufwand und ohne, daß Teile ausgewechselt werden müssen, eine sofortige Umstellung bei der fließbandmäßigen Herstellung von Betonplatten einer Größe auf Betonplatten einer anderen Größe möglich ist.The invention has for its object to design a device of the type described so that with it without assembly work and without the need to replace parts, an immediate change in the assembly line production of concrete slabs of one size on concrete slabs of another size is possible.

Die Aufgabe ist erfindungsgemäß durch die Kombination der folgenden Merkmale gelöst:

  • a) auch die Stirnabstellungen sind an Schubvorrichtungen befestigt,
  • b) die Abstellungen sind durch die Schubvorrichtungen in horizontaler Richtung senkrecht zu ihrer Schalungsfläche verstellbar,
  • c) jede Schubvorrichtung ist auf einem Schlitten oder Wagen Angeordnet und mit diesem parallel zur Schalungsfläche der mit ihre verstellbaren Abstellung verschiebbar,
  • d) die Abstellungen sind nacheinander auf die Palette derart auffahrbar, daß jede Abstellung mit einer Stirnseite gegen die Schalungsfläche einer anderen Abstellung stößt.
The object is achieved according to the invention by combining the following features:
  • a) the end stops are also attached to pushing devices,
  • b) the stops can be adjusted by the pushing devices in the horizontal direction perpendicular to their formwork surface,
  • c) each pushing device is arranged on a slide or carriage and can be moved with it parallel to the formwork surface with its adjustable shelf,
  • d) the shelves can be moved one after the other onto the pallet in such a way that each shelf abuts with one end face against the formwork surface of another shelf.

Einige der in den Unteransprüchen angegebenen Weiterbildungen der Erfindungen werden nachfolgen noch kommentiert.Some of the developments of the inventions specified in the subclaims will be commented on below.

In den meisten Fällen müssen Betonplatten mit Armierungen versehen sein, die über die eigentliche Betonplatte hinausstehen. Sollen diese Armierungen nicht an der Oberseite einer solchen Betonplatte, sondern beispielsweise aus der Mitte einer Schmalseite herausstehen, so werden Abstellungen verwendet, die zwei- oder mehrteilig sind. Die Abstellungen bestehen in diesem Fall aus einzelnen Balken, die übereinander angeordnet werden. Der unterste Balken wird zuerst auf die Palette aufgefahren, dann wird die Armierung eingelegt, so daß die überstehenden Enden der Armierung auf dem untersten Balken aufliegen. Dann wird ein oberer Balken auf die hinausstehenden Enden der Armierungen aufgelegt. Um bei dieser Herstellungsart zu gewährleisten, daß zwischen den einzelnen Balken einer solchen Abstellung kein Beton ausfließen kann, kann vorgesehen sein, daß die einzelnen Balken an den entsprechenden Stellen Aussparungen haben, in die sich die einzelnen Enden der Armierung einfügen. Die abstellungen umschließen dann dicht die Armierung und ein Ausfließen von Beton kann nicht auftreten.In most cases, concrete slabs must be provided with reinforcements that protrude beyond the actual concrete slab. If these reinforcements are not to protrude from the top of such a concrete slab, but rather, for example, from the middle of a narrow side, then supports are used that are in two or more parts. In this case, the shutdowns consist of individual bars that are arranged one above the other. The bottom beam is first moved onto the pallet, then the reinforcement is inserted so that the protruding ends of the reinforcement rest on the bottom beam. Then an upper bar is placed on the protruding ends of the reinforcements. In order to ensure in this type of production that no concrete can flow out between the individual beams of such a stand, it can be provided that the individual beams have recesses at the corresponding points, into which the individual ends of the reinforcement fit. The stops then tightly enclose the reinforcement and concrete cannot flow out.

Da es bei dieser Herstellungsort notwendig ist, daß der Längseisenabstand der Armierungen konstant gehalten werden muß, wird vorgeschlagen, die Balken einer solchen mehrteiligen Abstellung an denjenigen Flächen, and denen diese Balken mit den überstehenden Enden der Armierung in Kontakt kommen, mit einer elastisch verformbaren Schicht zu versehen. Die Balken einer solchen Armierung werden nach nach dem Einlegen der Armierung zusammengedrückt, so daß die auf den Balken befindlichen Schichten sich verformen und eng um die Enden der Armierung schließen. Anstelle die einzelnen Balken mit einer elastischen Schicht zu versehen, kann auch vorgesehen sein, daß die Balken selbst aus elastischem Material bestehen.Since it is necessary at this place of manufacture that the longitudinal iron spacing of the reinforcements must be kept constant, it is proposed that the beams of such a multi-part storage on the surfaces where these beams come into contact with the protruding ends of the reinforcement with an elastically deformable layer to provide. The beams of such a reinforcement are compressed after the reinforcement has been inserted, so that the layers on the beams deform and close tightly around the ends of the reinforcement. Instead of providing the individual bars with an elastic layer, it can also be provided that the bars themselves consist of elastic material.

Beim Rütteln und Verdichten der Betonmasse wird die Palette auf einen Rüttelbock gesetzt. Da die Palette beim Rütteln vertikale Bewegungen ausführt, muß gewährleistet sein, daß die Abstellungen sich nicht von der Palette abheben und Beton seitlich austreten kann. Hierzu ist vorgesehen, daß die Abstellungen einen messerartigen Ansatz aufweisen, der im stumpfen Winkel gegen die Palettenoberseite gerichtet ist und auf ihr aufliegt. Dieser messerartige Ansatz hat federnde Eigenschaften, so daß bei einer vertikalen Schwingbewegung der Palette sich das Ende dieses Ansatzes immer auf der Paletten-Oberseit befindet und dort dichtend schließt. Da im Laufe der Zeit dieser messerartige Ansatz einem Verschleiß unterliegt, ist vorgesehen, daß eine entsprechend geformte Leiste an der Abstellung abnehmbar angebracht ist.When the concrete mass is shaken and compacted, the pallet is placed on a vibrating stand. Since the pallet makes vertical movements when shaken, it must be ensured that the shelves do not stand out from the pallet and that concrete can emerge from the side. For this purpose, it is provided that the stops have a knife-like approach, which is directed at an obtuse angle against the top of the pallet and rests on it. This knife-like approach has resilient properties, so that when the pallet swings vertically, the end of this approach is always on the top of the pallet and closes there in a sealing manner. Since this knife-like approach is subject to wear over time, it is provided that a correspondingly shaped bar is removably attached to the parking space.

Bei mehrteiligen Abstellungen, die aus elastischem Material bestehen, weist der unterste Balken einen entsprechenden prismatischen Querschnitt auf, so daß die Dachkante des Prismas auf der Oberseite der Palette aufliegt.In the case of multi-part shutdowns consist of elastic material, the bottom bar has a corresponding prismatic cross-section, so that the roof edge of the prism rests on the top of the pallet.

Um zu verhindern, daß sich beim Rütteln der Palette die Schwingungen auf die Schubvorrichtungen übertragen, an denen die Abstellungen befestigt sind, ist zwischen jede Abstellung und der zugehörigen Schubvorrichtung ein Schwingungsdämpfendes Verbindungselement angebracht.In order to prevent the vibrations from being transmitted to the pushing devices to which the racks are attached when the pallet is shaken, a vibration-damping connecting element is fitted between each rack and the associated pushing device.

Soll die Palette nicht von unten her in ihre Beschickungsposition gefahren werden, sondern nur in einer Ebene bewegt werden, so ist vorgesehen, eine der Abstellungen anzuheben oder abzusenken, so daß die mit der Betonplatte versehene Palette über diese Abstellung hinweg oder unter ihr hindurch gefahren werden kann.If the pallet is not to be moved into its loading position from below, but only moved in one plane, it is provided to raise or lower one of the shelves so that the pallet provided with the concrete slab is moved over or below this shelf can.

Im folgenden wird nun die Vorrichtung anhand der in den Figuren dargestellten Ausführungsbeispiele beschrieben und näher erläutert.The device will now be described and explained in more detail with reference to the exemplary embodiments shown in the figures.

  • 2 shows a longitudinal section through a device according to the invention,
  • 3 shows a cross section through a device according to the invention,
  • 4 shows a first embodiment of a shutdown,
  • Fig. 5 shows a second embodiment of a shutdown.

Die Figure 1 zeigt eine Draufsicht auf eine Anordnung, mit der das erfindungsgemäße Verfahren durchgeführt werden kann. Es sind zwei Rollenbahnen 71, 72 erkennbar, auf denen eine Palette 2 unter Schienen 55 hindurch in eine Position gefahren werden kann, die unterhalb der Beschickungsposition liegt. Auf den Schienen 55 befinden sich Wagen oder Schlitten, die Schubvorrichtungen 6 tragen. An diesen Schubvorrichtungen 6 befinden sich die Abstellungen 3. Bei der im Beispielsfall dargestellten Herstellung von rechteckigen Betonplatten sind um die Beschickungsposition vier Paare von Schienen 55 und entsprechende Wagen oder Schlitten 5 angeordnet, deren Bewegungsrichtung jeweils parallel zu den Seitenflächen der herzustellenden Betonplatte läuft. Wie in Figur 1 erkennbar ist, werden die Abstellungen 3 so auf die Palette 2 aufgefahren, daß jeweils eine Längsseite 31 einer solchen Abstellung gegen eine Stirnseite 32 einer anderen Abstellung stößt. Wie sich an der Figur 1 erkennen läßt, können mit diesem Mittel bei entsprechendem Vorschieben der Abstellungen 3 mittels der Vorschubeinrichtung 6 beliebige Größen von Betonplatten hergestellt werden.Figure 1 shows a plan view of an arrangement with which the inventive method can be carried out. Two roller conveyors 71, 72 can be seen, on which a pallet 2 can be moved under rails 55 into a position which is below the loading position. On the rails 55 there are carriages or sleds which carry pushers 6. The stops 3 are located on these pushers 6. In the production of rectangular concrete slabs shown in the example, four pairs of rails 55 and corresponding carriages or slides 5 are arranged around the loading position, the direction of movement of which runs parallel to the side surfaces of the concrete slab to be produced. As can be seen in FIG. 1, the shelves 3 are moved onto the pallet 2 in such a way that a long side 31 of such a shelf abuts an end face 32 of another shelf. As can be seen in FIG. 1, any size of concrete slab can be produced with this means by appropriately advancing the stands 3 by means of the feed device 6.

Die Figur 2 zeigt einen Längsschnitt durch eine erfindungsgemäße Vorrichtung. Auf Schienenpaaren 55 laufen je ein Wagen 51, 52. Es befindet sich auf jedem Wagen 51, 52 eine Vorschubeinrichtung, die in Fig. 2 als Stange dargestellt ist. An ihnen ist eine Abstellung 3 angebracht. Zwischen diesen befindet sich die noch nicht ausgehärtete Betonplatte 1. Die Palette 2 sitzt auf Rüttelböcken 8. Mit hilfe einer Hubvorrichtung 9, die insbesondere eine Kolbenzylinderanordnung ist, kann die Palette samt den Rüttelböcken 8 aus der Beschickungsposition abgesenkt und auf die Rollenbahnen 71, 72 abgesenkt werden. Sie kann aus dieser Position unter den in der Figur 2 nicht dargestellten Schlitten oder Wagen 53, 54 hindurchgefahren werden.FIG. 2 shows a longitudinal section through a device according to the invention. One carriage 51, 52 each run on rail pairs 55. A feed device, which is shown in FIG. 2 as a rod, is located on each carriage 51, 52. A rack 3 is attached to them. Between them is the not yet hardened concrete slab 1. The pallet 2 is seated on vibrating jacks 8. With the aid of a lifting device 9, which is in particular a piston-cylinder arrangement, the pallet together with the vibrating jacks 8 can be lowered from the loading position and lowered onto the roller conveyors 71, 72 will. It can be moved from this position under the carriage or carriage 53, 54, not shown in FIG. 2.

Die Figur 3 zeigt einen Querschnitt durch eine Vorrichtung, mit der das erfindungsgemäße Verfahren ausgeführt werden kann. Die Palette 2 wird von links auf den Rollenbahnen 71, 72 auf einen im abgesenkten Zustand befindlichen Rüttelbock 8 aufgefahren. Der Rüttelbock 8 wird dann mit einer Hydraulikvorrichtung 9 angehoben, so daß die Palette 2 mit ihrer Oberseite die Unterkanten der Abstellungen 3 berührt. Dieser Zustand ist in Figur 3 dargestellt.FIG. 3 shows a cross section through a device with which the method according to the invention can be carried out. The pallet 2 is moved from the left onto the roller conveyors 71, 72 onto a vibrating block 8 which is in the lowered state. The vibrating block 8 is then raised with a hydraulic device 9, so that the upper side of the pallet 2 touches the lower edges of the positions 3. This state is shown in Figure 3.

Die Figur 4 zeigt einen Querschnitt durch eine einzelne Abstellung, die an einer Vorschubeinrichtung befestigt ist. Die Vorschubeinrichtung ist eine Kolbenzylindervorrichtung 64, wobei an dem Kolben ein schwingungsdämpfendes Verbindungselement 61 befestigt ist. An diesem Schwingmetall 61 wiederun ist die Abstellung 3 befestigt. Sie weist an ihrer Unterseite eine Leiste 62 auf, die mit einem messerartigen Ansatz 63 versehen ist. Die Schneide 65 dieses Ansatzes 63 liegt auf der Oberseite 21 der Palette 2 auf. Wie weiter anhand der Figur 4 erkennbar ist, ist die Frontfläche 38 der Abstellung 3 um einen kleinen Winkel, etwa um 2° gegen die Vertikale geneigt. Die Leiste 62 ist mit Schrauben 66 an der Abstellung befestigt, so daß. sie leicht ausgetauscht werden kann. Dies ist notwendig, da sich beim Rütteln des Betons der messerartige Ansatz 63 auf der Oberfläche der Palette 2 abschleift.FIG. 4 shows a cross section through a single rack that is attached to a feed device. The feed device is a piston-cylinder device 64, a vibration-damping connecting element 61 being fastened to the piston. At this vibrating metal 61 again the parking space 3 is attached. It has a bar 62 on its underside, which is provided with a knife-like extension 63. The cutting edge 65 of this extension 63 lies on the top 21 of the pallet 2. As can further be seen from FIG. 4, the front surface 38 of the rack 3 is inclined at a small angle, approximately 2 °, from the vertical. The strip 62 is fastened to the parking space with screws 66, so that. it can be easily replaced. This is necessary because when the concrete is shaken, the knife-like attachment 63 grinds on the surface of the pallet 2.

In der Figur 5 ist eine weitere Ausführungsart für eine bei der erfindungsgemäßen Vorrichtung verwendete Abstellung dargestellt, Diese Ausführungsart wird insbesondere in Fällen verwendet, wo die Betonplatte mit Armierungen 4 versehen ist, die aus den Seitenflächen der Betonplatte herausstehen. Die Abstellung ist im dargestellten Fall zweiteilig ausgebildet. Sie besteht aus einem unteren Balken 33, der in seiner Unterseite eine prismatische Form aufweist, wobei die "Dachkante" 69 auf der Oberseite 21 der Palette 2 aufliegt. Diese "Dachkante" 69 erfüllt die gleiche Aufgabe, wie der messerartige Ansatz 63 in der Figur 4. Auf dem unteren Balken 33 befindet sich eine Schicht 37 aus elastisch verformbaren Material. Diese Schicht kann aus Gummi sein, sie kann aber auch aus einem anderen verformbaren Material sein, wie z.B. aus Schaumgummi. Die Enden 41 der Armierung 4, die über die Seitenflächen der Betonplatte hinausstehen sollen, befinden sich zwischen den Balken 33 und 34 der Abstellung. Der Balken 34 ist ebenfalls mit einer elastischen Schicht 37 versehen. Die Balken 33 und 34 umfassen dichtend das Ende 41 der Armierung 4, so daß kein Beton ausfließen kann. Falls das Gewicht des oberen Balkens 34 nicht zum dichtenden Schließen ausreicht, kann eine in der Figur 5 gestrichelt dargestellte Feder 39 vorgesehen sein. Diese Feder 39 kann ferner dazu geeignet sein, beim Rütteln des Betons ein Öffnen oder Auseinanderklaffen der beiden Balken 33 und 34 zu verhindern.FIG. 5 shows a further embodiment for a parking device used in the device according to the invention. This embodiment is used in particular in cases where the concrete slab is provided with reinforcements 4 which protrude from the side surfaces of the concrete slab. The shutdown is formed in two parts in the case shown. It consists of a lower bar 33, which has a prismatic shape in its underside, the “roof edge” 69 resting on the top 21 of the pallet 2. This "roof edge" 69 fulfills the same task as the knife-like extension 63 in FIG. 4. On the lower bar 33 there is a layer 37 made of elastically deformable material. This layer can be made of rubber, but it can also be made of another deformable material, such as foam rubber. The ends 41 of the reinforcement 4, which should protrude beyond the side surfaces of the concrete slab, are located between the beams 33 and 34 of the rack. The beam 34 is also provided with an elastic layer 37. The beams 33 and 34 sealingly enclose the end 41 of the reinforcement 4, so that no concrete can flow out. If the weight of the upper bar 34 is not sufficient for sealing closure, a spring 39 shown in dashed lines in FIG. 5 can be used be provided. This spring 39 can also be suitable for preventing the two beams 33 and 34 from opening or divergence when the concrete is shaken.

Der Arm 34 ist um ein Gelenk 35 schwenkbar. Dies ermöglicht es, die Armierung 4 ungehindert senkrecht von oben auf die Palette aufzulegen. Das Gelenk 35 befindet sich an einer Platte 36, die über ein Schwingungsdämpfendes Verbindungselement 61 mit der Kolbenstange 64 einer Kolbenzylindervorrichtung verbunden ist, welche die Vorschubeinrichtung im Sinne der Erfindung ist.The arm 34 is pivotable about a joint 35. This makes it possible to place the reinforcement 4 unhindered vertically on the pallet from above. The joint 35 is located on a plate 36, which is connected via a vibration-damping connecting element 61 to the piston rod 64 of a piston-cylinder device, which is the feed device in the sense of the invention.

Weiterhin ist dargestellt, daß die Frontfläche 38 der Abstellung 3 gegen die Vertikale geneigt ist, der Neigungswinkel beträgt in dem dargestellten Beispiel etwa 4°.Furthermore, it is shown that the front surface 38 of the shelf 3 is inclined to the vertical, the angle of inclination in the example shown is approximately 4 °.

Die Balken 33, 34 können, statt mit einer elastischen Schicht 37 versehen zu sein, ganz aus elastischem Material bestehen. Da in diesem Fall das elastische Material genügend dämpfende Eigenschaften aufweisen kann, kann unter Umständen bei einer solchen Ausgestaltung auf das Schwingmetall 61, das zwischen der Abstellung 3 und der Kolbenzylindervorrichtung 64 angebracht ist, verzichtet werden.Instead of being provided with an elastic layer 37, the beams 33, 34 can consist entirely of elastic material. In this case, since the elastic material can have sufficient damping properties, the oscillating metal 61, which is attached between the stop 3 and the piston cylinder device 64, can be dispensed with in such a configuration.
