Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Patentanspruchs 1 sowie Verfahren nach dem Oberbegriff des Patentanspruchs 9.The invention relates to a device according to the preamble of
Bei der Herstellung von Betondachsteinen nach dem Strangpressverfahren wird auf einem mit konstanter Geschwindigkeit geförderten Strang von aneinander stoßenden Unterformen gleicher Länge eine Frischbetonschicht als endloses Band aufgebracht, das auf der Oberseite durch Formwerkzeuge der für Betondachsteine üblichen Oberflächenkontur entsprechend geformt wird. Die kontinuierlich aufgebrachte Frischbetonschicht wird anschließend in einer Schneidstation jeweils am Ende einer jeden Unterform mittels eines als Messer ausgebildeten Schneidwerkzeugs zerschnitten, sodass jede Unterform einen einzelnen Formkörper trägt, hier einen Betondachsteinrohling. Der Betondachsteinrohling härtet anschließend in einer Trockenkammer auf seiner Unterform liegend aus und wird anschließend mit einer Oberflächenbeschichtung versehen. Ein Verfahren und eine Vorrichtung zur Herstellung von derartigen Betondachsteinen sind in der
Um bei mit Betondachsteinen der vorstehend genannten Art eingedeckten Dächern eine ausreichende Dichtigkeit gegen Schlagregen zu erzielen, ist es notwendig, dass sich die in einer First-Trauf-Linie benachbarten Betondachsteine überlappen. Die jeweilige Überlappungslänge ist dabei abhängig von der jeweiligen Dachneigung, d. h. bei einer sehr starken Dachneigung kann die Überlappung geringer gewählt werden als bei einer sehr geringen Dachneigung.In order to achieve sufficient tightness against driving rain in roofs covered with concrete roof tiles of the type mentioned above, it is necessary that the concrete roof tiles adjacent in a first-eaves line overlap. The respective overlap length is dependent on the respective roof pitch, d. H. With a very strong roof pitch, the overlap can be chosen to be lower than at a very low roof pitch.
Die Verwendung dieser Betondachsteine bei Dächern mit einer Neigung von weniger als 22° - hierzu zählen insbesondere nichtbewohnte Wirtschaftsgebäude - ist problematisch. Da hierbei eine sehr große Überlappungslänge der Dachsteine erforderlich ist, muss zwischen First und Traufe eine sehr hohe Anzahl an parallelen Dachsteinreihen verlegt werden. Der hohe Bedarf an Dachsteinen und die Erstellung einer an die Anzahl der Dachsteinreihen angepassten Dachlattenkonstruktion erhöhen die Material- und Arbeitskosten erheblich. Wirtschaftsgebäude werden daher häufig mit billigeren und leichteren Bedachungsmaterialien, wie z. B. Metallblech oder Faserzementplatten eingedeckt.The use of these concrete roof tiles for roofs with a slope of less than 22 ° - this includes in particular uninhabited farm buildings - is problematic. Since this requires a very large overlap length of the roof tiles, a very high number of parallel rows of roof tiles must be laid between ridge and eaves. The high demand for roof tiles and the creation of a roof slat construction adapted to the number of rows of roof tiles significantly increase material and labor costs. Farm buildings are therefore often with cheaper and lighter roofing materials, such. B. sheet metal or fiber cement panels covered.
Um trotzdem bei diesen Gebäuden Betondachsteine ohne Nachteil einsetzen zu können, ist man dazu übergegangen, die Betondachsteine auf ihrer Oberseite im Bereich ihres kopfseitigen Randes mit einer Wassersperre zu versehen, die den Eintrieb von Schlagregen verhindert. Auf diese Weise können die hohen Material- und Arbeitskosten vermieden werden.In order nevertheless to be able to use concrete roof tiles without detriment in these buildings, one has proceeded to provide the concrete roof tiles on their upper side in the region of their head-side edge with a water barrier, which prevents the input of driving rain. In this way, the high material and labor costs can be avoided.
Aus
Außerdem sind Vorrichtungen bekannt, mit denen Dachsteine hergestellt werden können, die an einem Ende einen quer verlaufenden Vorsprung aufweisen (
Diese Aufgabe wird gemäß den Merkmalen der Patentansprüche 1 oder 9 gelöst.This object is achieved according to the features of patent claims 1 or 9.
Die Erfindung betrifft somit eine Vorrichtung und ein Verfahren zum Herstellen von Wassersperren in Dachsteinrohlingen, die noch nicht verfestigt sind. Die Vorrichtung weist ein Formstück mit einer Ausnehmung sowie einen Stempel auf. Das Formstück wird oberhalb des Endes eines Dachsteinrohlings angeordnet. Sodann wird mit dem Stempel die hintere Kante des Dachsteinrohlings ganz oder teilweise nach oben gedrückt. Anschließend trocknet der Dachsteinrohling aus.The invention thus relates to an apparatus and a method for producing water barriers in roofing bricks, which are not yet solidified. The device has a shaped piece with a recess and a stamp. The fitting is placed above the end of a roof tile blank. Then the back edge of the roof tile blank is pressed wholly or partially upwards with the stamp. Then the Dachsteinrohling dries out.
Der mit der Erfindung erzielte Vorteil besteht insbesondere darin, dass im Vergleich zu den aus dem Stand der Technik bekannten Lösungen kein separater Frischbeton verwendet wird, sodass zwischen der Wassersperre und dem Betondachstein keine zur Rissbildung neigende Fügestelle entsteht.The advantage achieved by the invention is, in particular, that no separate fresh concrete is used in comparison to the solutions known from the prior art, so that no joint tends to crack between the water seal and the concrete roof tile.
Weiterhin kann in einer Produktionslinie die Wassersperre an mehreren Dachsteinen nacheinander und bei üblicher Produktionsgeschwindigkeit hergestellt werden.Furthermore, in a production line, the water barrier can be produced on several roof tiles one after the other and at the usual production speed.
Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im Folgenden näher beschrieben.Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

Bewegt sich nun der Stempel 4, der eine abgeschrägte Frontseite 6 besitzt, auf den Dachsteinrohling 1 zu, so kommt er mit seiner Spitze 7 mit einem Punkt der Frontseite 8 des Dachsteinrohlings 1 in Berührung. Wird der Stempel 4 weiter nach links bewegt, hebt er den oberen Teil des vorderen Bereichs des Dachsteinrohlings 1 nach oben und drückt ihn in eine Aussparung 9 des Formstücks 3.Moves now the

Um das rechte Ende des Kolbens 14 ist eine Spiralfeder 38 geschlungen, die sich auf der Buchse 15 abstützt und den Kolben 14 nach rechts drückt. Eine Linksbewegung dieses Kolbens 14 kann somit nur gegen die Kraft der Feder 38 erfolgen.To the right end of the
Rechts von dem Halteelement 5 befindet sich ein Hebel mit zwei Hebelarmen 16, 17, die in einem stumpfen Winkel zueinander angeordnet sind. An den Enden dieser Hebelarme 16, 17 ist jeweils eine Rolle 18, 19 vorgesehen, während die Verbindungsstelle der beiden Hebelarme 16, 17 in einem Drehlager 20 ruht. Die Rolle 18 liegt an dem Halteelement 5 an. Dagegen liegt die Rolle 19 an der Unterseite einer ortsfesten Nocke 21 an.To the right of the holding
Der Stempel 4, das Formstück 3 und die Hebelarme 16, 17 werden mittels eines Förderbands oder eines Zahnriemens von rechts nach links bewegt. Die Geschwindigkeit entspricht dabei während des Bearbeitungsvorgangs der Geschwindigkeit des Dachsteinrohlings 1, mit der dieser von rechts nach links bewegt wird. Gelangt die Rolle 19 in den mittleren Bereich 99 der ortsfesten Nocke 21, die nach unten ausgebuchtet ist, wird die Rolle 19 nach unten gedrückt.The
Hierauf drehen sich die beiden Hebelarme 16, 17 im Uhrzeigersinn um die Drehachse 20, vgl. Pfeil 25, wodurch die Rolle 18 das Halteelement 5 nach links schiebt. Dieses Halteelement 5 bewegt seinerseits den mit ihm fest verbundenen Stempel 4 nach links, der - wie bereits beschrieben - Material des Dachsteinrohlings 1 in die Aussparung 9 des Formstücks 3 drückt. Auch der Kolben 14 wird hierbei gegen die Kraft der Feder 38 nach links verschoben. Nach einer bestimmten Zeit gelangt die Rolle 19 wieder an eine nicht ausgebuchtete Stelle des Nockens 21, sodass sich der Stempel 4 zurückzieht. Das Zurückziehen des Stempels wird durch die Feder 38 beschleunigt, die um das rechte Ende des Kolbens 14 geführt ist.Thereafter, the two

Die Nocke 21 ist linksseitig um einen Bolzen 58 schwenkbar gelagert und rechtsseitig mit einem Pressluftzylinder 22 verbunden, der die Nocke 21 in einer waagerechten Position hält. Entstehen bei der Verformung des Dachsteinrohlings 1 zu hohe Widerstandskräfte, weil beispielsweise der Dachsteinrohling fertigungsbedingt in seiner Länge geringfügig variiert und entsprechend mehr Frischbeton verformt werden muss, dann überwindet die auf die Nocke 21 einwirkende Kraft die Kraft des Pressluftzylinder 22 so dass die Nocke 21 zur Entlastung nach oben hin entweichen kann. Es kann auch das ganze Ende 10, 11 des Dachsteinrohlings 1 umgeklappt werden und nicht nur ein Teilstück 11, wenn der Stempel 4 und die Aussparung 9 größer gemacht werden.The

Die Unterform 2 wird bei der Überführung von den Fördersträngen 57 auf die Hebebühne 34 durch Reibung mit der Hebebühne abgebremst, da die Hebebühne 34 beim Einlaufen der Unterform 2 angehoben wird. Mit Hilfe eines nicht dargestellten Pressluftzylinders wird hierauf die Unterform 2 bis an den Anschlag 35 bewegt. In dieser Position, welche die
Nachdem der Dachsteinrohling 1 mit der Wassersperre 11 versehen ist, wird er mittels der Hebebühne 34 wieder auf der Transportvorrichtung abgelegt und nach links transportiert. Jetzt kann mit der gleichen Vorrichtung der nächste Dachsteinrohling bearbeitet werden, der von rechts kommt.After the
Das in den
Da für alle Dachsteinrohlinge, die nacheinander angeliefert werden, die gleiche Bearbeitungsvorrichtung verwendet wird, kann die Bearbeitung eines neuen Dachsteinrohlings erst dann erfolgen, wenn die Bearbeitung des vorangegangenen Dachsteinrohlings beendet ist. Die Zufuhr von Unterformen 2 zur Formstation 40 bis 43, 45 wird deshalb in der Regel während der Bearbeitung eines Dachsteinrohlings 1 unterbrochen. Eine Unterbrechung ist jedoch dann nicht erforderlich, wenn der Abstand zwischen zwei Dachsteinrohlingen so groß ist, dass der gerade bearbeitete Dachsteinrohling fertig ist und abgelegt werden kann, bevor der nächste Dachsteinrohling ankommt.Since the same processing device is used for all Dachstein blanks that are delivered one after the other, the processing of a new Dachsteinrohlings can only be done when the processing of the previous Dachsteinrohlings is completed.

Hierbei ist ein Formstück 3-3"' fest und ein Stempel 4-4"' jeweils beweglich an jeweils einem dieser Wagen 40 bis 43 angebracht, die sich im Uhrzeigersinn auf einer geschlossenen Bahn 45 bewegen und von einem Zahnriemen angetrieben werden. Um die bei der Ausformung des Dachsteinrohlings 47 entstehenden Kräfte aufzunehmen, wird die auf einem Träger 44 befindliche Unterform 53 geführt und zusätzlich durch einen Anschlag 51 eines ersten Wagens 43 und einen Schieber 52 eines zweiten, nachfolgenden Wagens 42 fixiert. Anschlag 51 und Schieber 52 werden dabei durch hintere und vordere Kanten von Platten 49,49', 49", 49"' realisiert, von denen jeder Wagen 40 bis 43 eine besitzt.Here, a fitting 3-3 "'fixed and a punch 4-4"' are each movably attached to each one of these
Da für die Ausformung der Wassersperre am Dachsteinrohling 47 eine bestimmte Zeit erforderlich ist, müssen für die Bearbeitung weiterer Dachsteine 46, 48 auf der geschlossenen Bahn 45 mehrere Wagen 40 bis 43 vorhanden sein und während der Ausformung parallel zu dem Träger 44 geführt werden. Bezogen auf die
Um jede Relativbewegung zwischen dem am Wagen 40 bis 43 angebrachten Formstück 3-3'" und dem Dachsteinrohling 1 selbst zu verhindern, übernimmt der jeweils bearbeitende Wagen, z. B. 42, mittels des Schiebers 52 mit integrierter Zentrierung während der Ausformung auch den Weitertransport in der Fördereinrichtung. Wird z. B. der Dachsteinrohling 46 von der Zufördereinrichtung 50 auf den Träger 44 geschoben, wenn dort der Wagen 42 noch die Position des Wagens 41 einnimmt, so endet dieses Verschieben, wenn zwischen dem Dachstein 46 und der Zufördereinrichtung kein Kontakt mehr besteht. Jetzt fährt der Wagen 42 mit seinem Schieber 52 gegen das rechte Ende des Dachsteinrohlings 46 bzw. seiner Unterform 55 und schiebt die Unterform 55 nach links bis zum Anschlag 51 des Wagens 43.In order to prevent any relative movement between the fitting 3-3 '"attached to the

Die Wagen 40 bis 43 fahren mit höherer Umlaufgeschwindigkeit als für einen Arbeitstakt erforderlich. Unter Arbeitstakt wird dabei die Anzahl der pro Minute bearbeiteten Dachsteinrohlinge verstanden. Hierdurch wird erreicht, dass nicht mehr Dachsteinrohlinge angeliefert werden, als bearbeitet werden können.The
Durch Verringerung der Umlaufgeschwindigkeit der Wagen 40 bis 43 wird erreicht, dass der Betondachstein 46 mit Unterform 55 den Anschlag 51 des Wagens 42 einholt. Der Betrag der Geschwindigkeitsreduzierung richtet sich dabei nach der tatsächlichen Länge der Lücke f zwischen den Betondachsteinen 46,47 mit Unterformen 55, 53. Nachdem der Dachsteinrohling 46 mit Unterform 55 den Anschlag 51 des Wagens 42 eingeholt hat, wird die Umlaufgeschwindigkeit der Wagen 40 bis 43 wieder erhöht. Der nächste Wagen schiebt dann, wie bereits erwähnt, den Dachsteinrohling weiter. Durch einen entsprechenden Geschwindigkeitsablauf erfolgt auch die Anpassung des Arbeitstaktes der in der
Es werden somit zunächst die aus einer Dachsteinmaschine kommenden Unterformen 53, 54, 55 mit den darauf liegenden Dachsteinrohlingen 46, 47, 48 mittels eines Zuführförderers 50 einer Formstation 40 bis 43, 45 zugeführt. Hierauf wird eine zugeführte Unterform 53 von einem Schieber 52 eines ersten Wagens 42 an den Anschlag 51 eines zweiten Wagens 43 angedrückt. Sodann wird der Wagen 42 bei dieser Bewegung an der Nocke 21 entlang geführt, wobei der Stempel 4 mittels des Hebelmechanismus 16, 17 die Wassersperre an den Dachsteinrohling 47 anformt. Anschließend verlässt der Anschlag 51 die Unterform 53, und die Unterform 53 wird vom Schieber 52 auf den Abführförderer 56 geschoben.There are thus first coming from a Dachsteinmaschine
