Abstract

Apparatus for finishing prefabricated concrete staircases, has horizontal supports (1) carrying the moulded block (2) with its steps uppermost, for sideways movement, and for each step, there is installed a motor (5) carrying a grinding disc (6) for e.g. the horizontal face and another motor (10) at right angles to it, with another grinding disc (11) for the vertical face. All these motors are carried by vertical supports (7) in turn supported by horizontal rails (8) mounted at each end in vertical pedestals (4), so that the motors may be raised and lowered, also moved to and fro, into their working position.

Description

Durchlaufmaschine für das Schleifen vorgefertigter Treppenläufe oder dergleichen aus Beton, Zement oder dergleichen Für die Herstellung von Treppen ist es bekannt, eine ganze Treppe als Formkörper in Zement oder Beton einstückig zu fertigen. Eine solche Treppe bedarf aber noch der Bearbeitung der Stufen und Verbindungs- bzw. Stellabschnitte. Dies war bisher ein arbeitsaufwendiger und zeitraubender Vorgang. Die vorliegende Erfindung hat sich die Aufgabe gestellt, diese Arbeiten wesentlich zu verkürzen und zu vereinfachen. Die Lösung erfolgt dadurch, daß für vorgefertigte Treppenläufe od. dgl. aus Beton, Zement od. dgl. soviel Werkzeuge vorgesehen sind, daß alle gewünschten Flächen bei einer gegenseitigen Bewegung zwischen Werkzeug und Treppe parallel zu der Längsrichtung der Treppenstufen in einen einzigen, für alle Stufen gemeinsamen Arbeitsgang bearbeitet werden. Dadurch fallen alle schwierigen Umsteuerungen fort und die Arbeitszeit wird auf den kürzest möglichen Wert herabgesetzt. Meist wird die Treppe gegenüber den Werkzeugen bewegt, doch ist auch eine umgekehrte oder kombinierte Belegung möglich.Continuous machine for sanding prefabricated flights of stairs or the like made of concrete, cement or the like for the manufacture of stairs is it is known to have a whole staircase as a molded body in cement or concrete in one piece manufacture. However, such a staircase still requires the processing of the steps and connecting or control sections. This has previously been a laborious and time consuming process. The present invention has set itself the task of making this work essential to shorten and simplify. The solution is that for pre-made Staircases or the like made of concrete, cement or the like as many tools are provided, that all desired surfaces with a mutual movement between tool and stairs parallel to the longitudinal direction of the stairs in a single, for all stages can be processed together. This makes all difficult ones fall Reversals continue and the working hours will be as short as possible Decreased value. Usually the stairs are moved opposite the tools, but it is reverse or combined occupancy is also possible.

In einer bevorzugten Ausführungsform werden, um eine gegenseitige Bohinoerung der Werkzeuge zu vermeiden und dennoch alle Flachen restlos zu bearbeiten, die Werkzeuge neben- und insbesondere auch in Arbeitsrichtung hintereinander angeordnet.In a preferred embodiment are to be a mutual Avoid drilling the tools and still process all surfaces completely, the tools are arranged next to one another and, in particular, one behind the other in the working direction.

Bevorzugt wird jedes Werkzeug durch einen konzentrischen Motor unmittelbar angetrieben, wobei die Motoren bzw. die Werkzeuge einzeln und/oder gemeinsam in der Höhe und vorzugsweise auch seitwärts ver- und zustellbar sind. Es ist aber auch Kardan- oder Riemenantrieb möglich.Preferably, each tool is driven directly by a concentric motor driven, the motors or the tools individually and / or together in the height and preferably also to the side can be adjusted and adjusted. It is also Cardan or belt drive possible.

Die Erfindung wird anhand der Figur, welche ein Ausführungsbeispiel darstellt, noch näher erläutert.The invention is based on the figure, which shows an embodiment represents, explained in more detail.

Auf einer Fördervorrichtung, z. B. Förderbändern oder -Ketten 1, wird ein einstückiger Treppenrohling 2 in der StuEenlängsrichtung mit angemessener Geschwindigkeit bewegt. Für jede zu bearbeitende Einzeltr itt fläche 3 ist ein zugehöriger Motor 5 mit SchleiSçerkzeug 6 vorgesehen, das zweckmäßig von dem Motor unmittelbar und konzentrisch angetrieben wird.On a conveyor, e.g. B. conveyor belts or chains 1, is a one-piece staircase blank 2 in the longitudinal direction of the staircase at an appropriate speed emotional. For each single step surface 3 to be processed there is an associated motor 5 provided with SchleiSçerkzeug 6, which is expediently directly from the engine and is driven concentrically.

Jeder Motor 5 ist auf einer senkrechten Gleitbahn 7 mit nicht naher dargestellten Mitteln verschiebbar bzw. zustellbar.Each motor 5 is on a vertical slide 7 with no closer means shown displaceable or deliverable.

Die senkrechten Gleitführungen 7 sind ihrerseits auf einer von Böcken 4 getragenen Brücke 8 auch in der Querrichtung verschiebbar und einstellbar. Dies gilt für alle unter sich parallelen Werkzeuge 5, 6. Für die im Winkel von 9o oder annähern 90 Grad liegenden Stellflächen 9 sind ähnliche ebenfalls unter sich parallele entsprechend winkelversetzte Werkzeugmotoren lo mit Werkzeugen 11 vorgesehen, die aber in der Treppenbewegungsrichtung gegenüber den zuerst beschriebenen Trittstufen Motoren und Werkzeugen soweit versetzt sind, daß eine gegenseitige Behinderung vermieden ist. Die Treppe kann daher an allen gewünschten Flächen in einem einzigen Arbeitsgang fertig bearbeitet werden.The vertical sliding guides 7 are in turn on one of trestles 4 carried bridge 8 also displaceable and adjustable in the transverse direction. this applies to all tools 5, 6 parallel to each other. For those at an angle of 9o or approximately 90 degrees lying shelves 9 are similar also parallel to each other appropriately angularly offset tool motors lo provided with tools 11, the but in the direction of movement of the stairs compared to the steps described first Motors and tools are offset to such an extent that mutual hindrance is avoided is. The stairs can therefore be placed on all desired surfaces in a single operation can be finished.
