Abstract

On a production line (21), consisting essentially of skids (1), shuttering panels (2) and longitudinal and transverse shuttering sections (14; 15) are connected by means of pressing and advancing means (3) into non-positive and positive shutterings. These are advanced in steps over the entire length of the skids (1), the shutterings being fitted, in different working regions on the production line (21), with devices such as reinforcement, and the cast finished elements (17) being finished and unshuttered. The latter takes place mainly automatically and the shuttering elements are transported back automatically to the start of the production line (21) via removal, return transport and feed paths (6; 20; 4). By means of rockers (10) arranged in the return transport path (20), the order of the shuttering elements can be changed.

Description

Die vorliegende Erfindung betrifft einerseits ein Verfahren zum kontinuierlichen Herstellen von Decken- und Fassaden-Fertigelementen für den Hausbau, insbesondere von Deckenelementen gemäss der schweizerischen Patentanmeldung Nr. 2'103/79-9 und von Fassaden-Fertigelementen gemäss der schweizerischen Patentanmeldung Nr. 11180/81-1.The present invention relates on the one hand to a method for the continuous production of prefabricated ceiling and facade elements for house construction, in particular of ceiling elements according to Swiss patent application No. 2,103 / 79-9 and of prefabricated facade elements according to Swiss patent application No. 1 1 180 / 81-1.

Andererseits betrifft die vorliegende Erfindung Mittel zur Durchführung dieses Verfahrens.On the other hand, the present invention relates to means for performing this method.

Insbesondere bei der Herstellung von Standard-Bauelementen ist es interessant und wesentlich, die Herstellverfahren weitestgehend zu automatisieren und zu vereinfachen, um die wirtschaftlichen Vorteile, die das Bauen mit Fertigelementen bietet, auf die Fertigung dieser Teile, die in grossen Serien herstellbar sind, auszudehnen.In the production of standard components in particular, it is interesting and essential to automate and simplify the manufacturing processes as much as possible in order to extend the economic advantages that building with prefabricated elements offers to the production of these parts, which can be produced in large series.

Die herkömmlichen Verfahren zur Herstellung von Beton-Fertigelementen erfordern viel Handarbeit beim Bereitstellen der Schalungen und dem Ausschalen der Elemente. Zudem sind üblicherweise die diversen.Baustoffe wie Beton, Armierungseisen und Isolationen an mehrere Arbeitsplätze zu transportieren, wenn mehrere Elemente gleichzeitig oder kurzfristig nacheinander hergestellt werden. Dies führt zu einer unnötigen Verteuerung der Elementherstellung und zu fabrikationstechnischen Schwierigkeiten.The conventional methods for producing prefabricated concrete elements require a lot of manual work when providing the formwork and stripping the elements. In addition, the various building materials such as concrete, reinforcing iron and insulation are usually to be transported to several workplaces if several elements are used at the same time or be produced in quick succession. This leads to an unnecessary increase in the cost of element production and to manufacturing difficulties.

Der vorliegenden Erfindung liegt daher einerseits die Aufgabe zugrunde, ein Verfahren zum kontinuierlichen Herstellen von Decken- und Fassaden-Fertiglelementen zu schaffen, das rationell und wirtschaftlich ist und mit einem Minimum an Handarbeit auskommt, und das die Fertigung von einer Vielzahl von Standardelementen ermöglicht, ohne den Herstellungsfluss zu unterbrechen.The present invention is therefore based on the one hand the task of creating a method for the continuous production of ceiling and facade prefabricated elements, which is efficient and economical and requires a minimum of manual work, and which enables the production of a large number of standard elements without interrupt the manufacturing flow.

Andererseits soll die vorliegende Erfindung Mittel vorschlagen, die die Durchführung des Verfahrens ermöglichen.On the other hand, the present invention is to propose means which enable the method to be carried out.

Erfindungsgemäss wird diese Aufgabe durch ein Verfahren gelöst, wie es im Patentanspruch 1 definiert ist.According to the invention, this object is achieved by a method as defined in claim 1.

Die Mittel zur Durchführung des Verfahrens ihrerseits sind im Patentanspruch 5 definiert.The means for performing the method for their part are defined in claim 5.

Im folgenden wird die Erfindung im Detail beschrieben, wobei insbesondere für die Beschreibung der Mittel zum Durchführen des erfindungsgemässen Verfahrens auch auf die Zeichnung Bezug genommen wird. Dabei zeigt in letzterer

  • Fig. 1 einen teilweisen schematischen Grundriss der Fertigungsstrasse
  • Fig. 2 die beiden Enden der Fertigungsstrasse im Schnitt, und
  • Fig. 3 eine Wippe in der Rücktransportbahn im Schnitt.
The invention is described in detail below, reference being made in particular to the drawing for the description of the means for carrying out the method according to the invention. It shows in the latter
  • Fig. 1 is a partially schematic floor plan of the production line
  • Fig. 2 shows the two ends of the production line in section, and
  • Fig. 3 shows a rocker in the return path on average.

Das erfindungsgemässe Verfahren zeichnet sich dadurch aus, dass die Herstellung der Decken- oder Fassaden-Fertigelemente in mehrere, vorzugsweise sechs ungefähr gleich lange, Arbeitsschritte aufgeteilt und jedem Arbeitsschritt auf einer Fertigungsstrasse ein fester Bereich zugeordnet wird. Effektiv sind bei entsprechender Arbeitsvorbereitung und Arbeitsplanung die sechs folgenden Arbeitsschritte einzeln ausscheidbar:

  • l. Programmierung des herzustellenden Standard-Elementes, resp. der dazu benötigten Schalungsplatten und Längsabschalungen auf der Rücktransportbahn
  • 2. Einschieben der entsprechenden Schalungsplatten und Längsabschalungen auf die Fertigungsstrasse
  • 3. Vorbereiten der Schalung, indem die Armierung, die Querabschalungen und gegebenenfalls Schalungen für Ausschnitte eingelegt und zusammengekoppelt werden
  • 4. Beschickung der Schalungen mit den Elementmassen, z.B. Beton - Gasbeton - Beton und gegebenenfalls Isolationen
  • 5. Oberflächenbearbeitung der Fertigelemente und Ausziehen der Rohre für die Verbindungs- und Leitungslöcher
  • 6. Ausschalen der fertigen Elemente und Rücktransport der Schalungsteile, insbesondere der Schalungsplatten und Längsabschalungen auf der Rücktransportbahn
The method according to the invention is characterized in that the manufacture of the prefabricated ceiling or facade elements is divided into several, preferably six, work steps of approximately the same length and a fixed area is assigned to each work step on a production line. With appropriate work preparation and work planning, the following six work steps can effectively be eliminated:
  • l. Programming of the standard element to be manufactured, resp. the formwork panels and longitudinal formwork required for this on the return conveyor
  • 2. Push the appropriate formwork panels and longitudinal formwork onto the production line
  • 3. Prepare the formwork by inserting the reinforcement, the cross formwork and, if necessary, formwork for cutouts and coupling them together
  • 4. Loading the formwork with the element masses, eg concrete - gas concrete - concrete and possibly insulation
  • 5. Surface treatment of the prefabricated elements and pulling out the pipes for the connection and line holes
  • 6. Stripping the finished elements and returning the formwork parts, in particular the formwork panels and longitudinal formwork on the return path

Diese sechs Arbeitsschritte werden vorteilhafterweise auf einer Fabrikationsstrasse 21 ausgeführt, wie sie aus der Zeichnung ersichtlich ist. In Fig. 1 ist diese im Grundriss schematisch und geschnitten dargestellt, da die Länge beliebig gewählt werden kann. Im wesentlichen besteht sie aus parallelen, sich in einer horizontalen Ebene befindlichen Gleitkufen 1, auf welche die ganze Breite der Strasse überdeckende Schalungsplatten 2 zu liegen kommen. Diese Schalungsplatten 2 weisen vorteilhafterweise Rastermass-Breiten auf und werden derart aneinandergereiht, dass sie die gesamte Fabrikationsstrasse 21 mit ihren Gleitkufen überdecken. Sie werden durch Press- und Vorschubmittel 3, vorteilhafterweise in Form von Hydraulikpressen, gegeneinandergepresst, und schrittweise in Richtung des Pfeiles B über die gesamte Länge der Gleitkufen 1 vorwärtsgeschoben. Dabei wird jeweils vor jedem Schubschritt, bei eingezogenen Zylindern,der Hydraulikpressen, über eine Zuführbahn 4, im wesentlichen bestehend aus angetriebenen Transportrollen 5, eine weitere Schalungsplatte 2 in Richtung des Pfeiles A eingeschoben, die dann an die vorangehende angepresst wird. Durch den schrittweisen Vorschub der Schalungsplatten 2 wird automatisch am Ende der Gleitkufen 1 bei jedem Schubschritt eine Schalungsplatte 2 über das Ende der Gleitkufen 1 hinausgeschoben, sodass sie über eine geneigte Führung 7 (Fig. 2) auf eine Abführbahn 6 gleitet. Diese ist, wie die Zuführbahn 4, mit angetriebenen Transportrollen ausgestattet, auf welchen die Schalungsplatten 2 seitlich in Richtung des Pfeiles C ausgefahren werden können.These six work steps are advantageously carried out on a production line 21, as can be seen from the drawing. In Fig. 1 this is shown schematically and in section in the plan, since the length can be chosen arbitrarily. It essentially consists of parallel skids 1 located in a horizontal plane, on which formwork panels 2 covering the entire width of the road come to rest. These formwork panels 2 advantageously have grid widths and are strung together in such a way that they cover the entire production line 21 with their skids. They are pressed against each other by pressing and advancing means 3, advantageously in the form of hydraulic presses, and are gradually pushed in the direction of arrow B over the entire length of the skids 1. Before each pushing step, when the cylinders are retracted, the hydraulic presses, a further shuttering plate 2 is inserted in the direction of arrow A via a feed path 4, essentially consisting of driven transport rollers 5, which is then pressed onto the preceding one. Due to the gradual advance of the formwork panels 2, a formwork panel 2 is automatically pushed over the end of the skids 1 at the end of the skids 1 at each pushing step, so that it slides over an inclined guide 7 (FIG. 2) onto a discharge track 6. Like the feed path 4, this is equipped with driven transport rollers on which the formwork panels 2 can be extended laterally in the direction of the arrow C.

Die durch die Hydraulikpressen 3 in Längsrichtung der Gleitkufen 1 zusammengepressten Schalungsplatten 2 dienen als Schalungsboden für das Giessen der Fertigelemente 17. An Stelle einzelner Schalungsplatten 2 lassen sich Längsabschalungen 14 einfügen, die, wie erstere, sich über alle Gleitkufen 1 erstrecken. Da wo auf der Fertigungsstrasse 21 ein Fertigelement 17 hergestellt werden soll, sind an entsprechenden Stellen zwischen zwei Längsabschalungen vor dem Anpressen der zweiten derselben, zwei Querabschalungen 15 einzulegen, die mittels Zapfen, die in Löcher der Längsabschalungen 14 eingreifen können, fest mit diesen verbindbar sind. Vorteilhafterweise weisen die Längsabschalungen in Rasterabständen durchgehende Löcher auf, in die, wie beschrieben, entweder Querabschalungen 15 einrastbar sind, oder aber Rohre 16 eingelegt werden, die zur Herstellung von Leitungs- und Verbindungslöchern in den Fertigelementen 17 dienen.The formwork panels 2 compressed by the hydraulic presses 3 in the longitudinal direction of the skids 1 serve as formwork floor for the casting of the prefabricated elements 17. Instead of individual formwork panels 2, longitudinal formwork 14 can be inserted which, like the former, extends over all skids 1. Where a prefabricated element 17 is to be produced on the production line 21, two transverse formworks 15 are provided at corresponding locations between two longitudinal formworks before the second of them is pressed on increase, which can be firmly connected to these by means of pins which can engage in holes in the longitudinal formwork 14. Advantageously, the longitudinal formwork has through holes at grid intervals, into which, as described, either transverse formwork 15 can be snapped in or pipes 16 are inserted which are used to produce line and connection holes in the prefabricated elements 17.

Durch das Verschieben um einen Schritt der zweiten Längsabschalung 14 wird ein kraft- und formschlüssiger Schalungsrahmen erzeugt, in welchen neben den besagten Rohren Armierungen und gegebenenfalls weitere Schalungselemente oder andere Mittel einsetzbar sind.By shifting one step of the second longitudinal formwork 14, a non-positive and form-fitting formwork frame is generated, in which reinforcements and possibly other formwork elements or other means can be used in addition to the said pipes.

In einem zweiten Arbeitsschritt, wenn die derart bereitgestellte Schalung in einer Mehrzahl von Schubschritten um mindestens eine Schalungs- resp. Fertigelementbreite auf den Gleitkufen 1 vorgeschoben worden ist, kann in einem zweiten Bereich der Fertigungsstrasse 21 die Schalung mit dem Baustoff der Fertigelemente 17 beschickt werden, wie in der Zeichnung mit einem Punktraster angedeutet ist, wobei es sich dabei vorwiegend um Beton, Gasbeton und gegebenenfalls Isolationsmittel handeln dürfte. Während der Zeit, in der in diesem zweiten Bereich der Fertigungsstrasse 21 die Schalung beschickt wird, kann im vorangehenden Bereich, beim Beginn der Gleitkufen 1, eine weitere Schalung in der oben beschriebenen Art und Weise vorbereitet werden.In a second step, if the formwork provided in this way in a plurality of pushing steps by at least one formwork or. Prefabricated element width has been advanced on the skids 1, the formwork can be loaded with the building material of the prefabricated elements 17 in a second area of the production line 21, as indicated in the drawing with a grid of dots, which are mainly concrete, gas concrete and possibly insulation should act. During the time in which the formwork is being loaded in this second area of the production line 21, another formwork can be prepared in the above area, at the start of the skids 1, in the manner described above.

Nach Abschluss dieser Arbeiten und dem weiteren Vorschub der ganzen Schalungsplatten 2 und Schalungen auf den Gleitkufen 1, kann in einem dritten Bereich der Fertigungsstrasse 21 die Oberfläche des gegossenen Fertigelementes 17 bearbeitet werden, sofern dies notwendig und gewünscht ist, bevor der eingegossene Baustoff, in der Regel Beton und Gasbeton, sich verfestigt. Gleichzeitig können die in die Löcher der Längsabschalungen eingelegten Rohre 16, vorteilhafterweise mit einem quer verschiebbaren Kabelzug 8 aus dem sich in Verfestigung befindlichen Fertigelement 17 heraus- und in die anschliessende Schalung hineingezogen werden, bevor diese mit den Baustoffen beschickt wird.After completing this work and further advancing the entire formwork panels 2 and formwork on the skids 1, the surface of the cast prefabricated element 17 can be in a third area of the production line 21 work, if this is necessary and desired, before the poured building material, usually concrete and gas concrete, solidifies. At the same time, the tubes 16 inserted into the holes of the longitudinal formwork can be pulled out of the prefabricated element 17, which is being solidified, and pulled into the subsequent formwork, advantageously with a transversely displaceable cable pull 8, before it is loaded with the building materials.

In einem weiteren und letzten, vierten Bereich der Fertigungsstrasse 21, am Ende der Gleitkufen 1, werden die Fertigelemente 14, wenn sie nach wiederholten Vorschubschritten der Schalungsplatten 2 durch die Hydraulikpressen 3 da anlangen, automatisch ausgeschalt, da die einzelnen Schalungsplatten 2 und Längsabschalungen 14 schräg nach unten weggleiten. Dadurch werden auch die Querabschalungen 15 automatisch freigegeben, sodass sie entfernt werden können. Durch das weitere Vorschieben der Schalungsplatten 2 wird das nunmehr ausgeschalte Fertigelement 17 auf eine Rollenbahn 9 geschoben, von wo es in ein Lager befördert werden kann.In a further and last, fourth area of the production line 21, at the end of the skids 1, the prefabricated elements 14 are automatically switched off when they arrive after repeated feed steps of the formwork panels 2 by the hydraulic presses 3, since the individual formwork panels 2 and longitudinal formwork 14 are inclined slide down. This also automatically releases the cross-formwork 15 so that it can be removed. By pushing the formwork panels 2 further, the finished element 17, which is now switched off, is pushed onto a roller conveyor 9, from where it can be conveyed to a warehouse.

Die bei jedem Schubschritt auf die Abführbahn 6 gelangenden Schalungsplatten 2 und Längsabschalungen 14 werden vorzugsweise mittels angetriebener Rollen 18 in Richtung des Pfeiles C quer ausgefahrn, bis sie, vorteilhafterweise durch einen Kettenzug 19, (Fig. 2) auf einer Rücktransportbahn 20, die parallel zur Fertigungsstrasse 21 neben dieser verläuft und ebenfalls im wesentlichen aus Gleitkufen 13 besteht, in Richtung des Pfeiles D (Fig. l) auf die Höhe der Zuführbahn 4 zurückbefördert werden. Da werden sie, durch die angetriebenen Transportrollen 5, in Richtung des Pfeiles A vor die Hydraulikzylinder 3 positioniert, um den nächsten Durchlauf auf der Fertigungsstrasse 21 zu,beginnen.The formwork panels 2 and longitudinal formwork 14 arriving at the discharge path 6 with each pushing step are preferably extended transversely in the direction of arrow C by means of driven rollers 18 until they, advantageously by a chain hoist 19 (FIG. 2), on a return conveyor path 20 which is parallel to the Production line 21 runs alongside this and also essentially consists of skids 13, in the direction of arrow D (FIG. 1) to be conveyed back to the level of the feed path 4. There they are positioned by the driven transport rollers 5 in the direction of arrow A in front of the hydraulic cylinders 3 in order to carry out the next pass on the production line street 21 to begin.

Um unterschiedlich breite und/oder mit unterschiedlich gestalteten Längsrändern versehene Fertigungselemente 17 herstellen zu können, ohne von Hand Schalungsplatten 2 und/oder Längsabschalungen 14 einlegen, resp. entfernen zu müssen, werden in die Rücktransportbahn 20 vorteilhafterweise Wippen 10 eingebaut, wie dies aus Fig. 3 hervorgeht. Auf diese können nicht benötigte Schalungsplatten 2 und Längsabschalungen 14 aufgeschoben und gelagert werden, bis sie für ein weiteres Fertigelement 17 wieder verwendet werden. Durch pneumatische oder hydraulische, seitlich der Rücktransportbahn 20 angeordnete Zylinder 11 können die aus Gleitkufen 12 bestehenden Wippen 10 zwischen die Gleitkufen 13 der Rücktransportbahn 20 eingeschwenkt werden, sodass entweder Schalungsplatten 2 oder Längsabschalungen auf die Wippe 10 aufgeschoben, auf ihr neutralisiert oder von ihr heruntergeschoben werden.In order to be able to produce manufacturing elements 17 of different widths and / or with differently designed longitudinal edges, without inserting formwork panels 2 and / or longitudinal formwork 14, respectively. need to be removed, rockers 10 are advantageously installed in the return transport path 20, as can be seen in FIG. 3. In this unneeded shuttering panels 2 and L can ängsabschalungen slid 14 and be stored until they are used for another prefabricated element 17 again. Pneumatic or hydraulic cylinders 11 arranged on the side of the return conveyor 20 can be used to pivot the rockers 10 consisting of skids 12 between the skids 13 of the return conveyor 20, so that either formwork panels 2 or longitudinal formwork are pushed onto the rocker 10, neutralized on it or pushed off by it .

Damit wird erreicht, dass weder Schalungsplatten 2 noch Längsabschalungen von Hand oder mittels anderen Hebe- und Transportmitteln angefasst werden müssen und dennoch die diversesten Fertigelemente 17 auf der Fertigungsstrasse 21 herstellbar sind. Lediglich die wesentlich kleineren und leichteren Querabschalungen müssen mit Hilfsmitteln jeweils vom Ende der Gleitbahnen 1 an deren Anfang zurücktransportiert werden, wobei auch für diese Elemente eine Rücktransportbahn vorgesehen werden kann.It is thereby achieved that neither formwork panels 2 nor longitudinal formwork need to be handled by hand or by means of other lifting and transport means, and yet the most diverse prefabricated elements 17 can be produced on production line 21. Only the much smaller and lighter cross-formworks have to be transported back from the end of the slideways 1 at the beginning with auxiliary means, and a return path can also be provided for these elements.

Dank dem erfindungsgemässen Verfahren und den erfindungsgemässen Mitteln zu dessen Durchführung lassen sich eine Vielzahl von unterschiedlichsten Standard-Fertigelementen 17 mit einem minimalen Aufwand an Handarbeit und Hilfsmitteln in einer kontinuierlichen Art und Weise herstellen. Der Fachmann erkennt die Vorteile des erfindungsgemässen Verfahrens gegenüber den herkömmlichen Verfahren für die Herstellung von Fertigelementen leicht. Er erkennt auch, dass sich mit den erfindungsgemässen Mitteln sowohl Dekkenelemente als auch Fassadenelemente herstellen lassen, gegebenenfalls mehrere seitlich nebeneinander.Thanks to the method according to the invention and the means according to the invention for carrying it out, a large number of very different standard prefabricated elements 17 can be produced in a continuous manner with a minimum of manual work and auxiliary means. The person skilled in the art easily recognizes the advantages of the method according to the invention over the conventional methods for the production of prefabricated elements. He also recognizes that the means according to the invention can be used to produce both ceiling elements and facade elements, if appropriate several laterally next to one another.

Die konstruktiven Details der Fertigungsstrasse, der Zuführ- und Abführbahnen, der Rücktransportbahn, des Kabelzuges, der Längs- und Querabschalungen und der Rollenbahnen brauchen dem Fachmann nicht gegeben zu werden, handelt es sich doch um herkömmliche mechanische Konstruktionen in Abhängigkeit der herzustellenden Fertigelemente, zu deren Realisierung es keiner erfinderischen Tätigkeit bedarf, sodern lediglich fachmännischen Wissens.The constructive details of the production line, the feed and discharge lanes, the return conveyor, the cable pull, the longitudinal and transverse formwork and the roller conveyors do not need to be given to the expert, since they are conventional mechanical designs depending on the finished elements to be manufactured, and their implementation requires no inventive step, merely expert W sodern KNOWLEDGE.

Es ist selbstverständlich, dass die dargestellten Mittel zur Durchführung des Verfahrens technisch anders gelöst werden können, insbesondere in Bezug auf die Rollenbahnen, den Kettenzug und die Wippen, ohne dass dadurch der Schutzumfang des Patentes verlassen wird.It goes without saying that the means shown for carrying out the method can be technically solved differently, in particular with regard to the roller conveyors, the chain hoist and the rockers, without thereby leaving the scope of protection of the patent.
