Description
ein Förderband 2 laufen, das vorzugsweise aus nicht rostendem Stahl hergestellt ist. Die kanalförmiEe Schalung 3 ist mit der Grundplatte I dicht verbunden. Zur Herstellung des Hohlraums im Betonbalken ist in der Schalung 3 ein Verdrängungsrohr 4 vorgesehen. Der '■ Preßkolben 5 hat die Form eines dem Querschnitt der Schalung 3 angepaßten, vorschieb- und zurückziehbaren Schiebers, durch dessen Stirnfläche das Verdrängungsrohr 4 und eventuell vorgesehene Balkenbewehrungen hindurchtreten können. Mit dem Preßkolben 5 wird aus einem Aufgabetrichter 6 iir die Schalung 3 eingetretener Frischbeton durch die Schalung geschoben und verdichtetrun a conveyor belt 2, which is preferably made of stainless steel. The canal shape Formwork 3 is tightly connected to the base plate I. To create the cavity in the concrete beam, in the formwork 3 a displacement pipe 4 is provided. The '■ The plunger 5 has the shape of one that is adapted to the cross section of the formwork 3 and can be advanced and retracted Slider, through the face of which the displacement pipe 4 and possibly provided beam reinforcement can pass through. With the plunger 5, the formwork 3 is entered from a feed hopper 6 iir Fresh concrete pushed through the formwork and compacted
Um eine vollständige Füllung der Schalung zu erreichen, werden deren beide seitliche Wände im n Bereich des Aufgabetrichters 6 von je einem quer zur Arbeitsrichtung des Preßkolbens 5 verschiebbaren Füllschieber 7 gebildet, die bei zurückgezogenem Preßkolben auseinanderfahrbar und vor Beginn des Ärbcitshubes des Preßkoibens 5 in die mit den a> Seitenwänden der Schalung 3 fluchtende Stellung zusammenfahrbar sind.In order to achieve a complete filling of the formwork, both of its side walls are placed in the n Area of the feed hopper 6, each of which can be displaced transversely to the working direction of the plunger 5 Filling slide 7 formed, which can be moved apart when the plunger is withdrawn and before the start of the Ärbcitshubes des Preßkoibens 5 in the with the a> Side walls of the formwork 3 aligned position can be moved together.
Nach der Befüllung der Schalung mit Frischbeton und dem Zusammenfahren der Füllschieber 7 wird die noch offene Oberseite des Füllbereichs mit einem verschieb- 2^ baren Deckel 8 formbündig verschlossen, wodurch der Füllbereich der Vorrichtung abgeschlossen istAfter filling the mold with fresh concrete and the moving together of the feed slide 7 still open top of the fillable form is closed flush with a displaceable lid cash 2 ^ 8, whereby the filling region of the apparatus is finished
Nach dem Schließen des Deckels 8 wird der Preßkolben 5 vorgeschoben, wodurch der eingefüllte Frischbeton durch die Schalung 3 gedrängt und so der Beton-Hohlbalken gebildet wird. Nach Beendigung des Arbeitshubes werden der Preßkolben 5 und der Schiebedeckel 8 zurückgezogen und die Füllschieber 7 seitlich auseinandergezogen, so daß erneut Frischbeton aus dem Aufgabetrichter 6 zutreten kann.After closing the cover 8, the plunger 5 is advanced, whereby the filled Fresh concrete pushed through the formwork 3 and so the concrete hollow beam is formed. After the Working stroke, the plunger 5 and the sliding cover 8 are withdrawn and the filling slide 7 laterally pulled apart so that fresh concrete can again enter from the feed hopper 6.
Der Deckel 8 fährt beim Schließvorgang an einer Säuberungszunge 9 an, die sich hierbei geringfügig anhebt und eventuell vor dem Deckel 8 eingeklemmte Kieskörner abstreift und mit nach oben nimmt. Eventuell verbleibende kleinere Körner ragen dann zwar noch nach unten heraus, kommen aber nur mit dem Beton in Berührung, da der Preßkolben 5 bei Beendigung des Arbeitshubes noch kurz vor der Klemmstelle des Deckels 8 liegt.During the closing process, the cover 8 approaches a cleaning tongue 9, which is slightly different in this case lifts and removes any jammed gravel grains in front of the cover 8 and takes them upwards. Any remaining smaller grains then stick out downwards, but only come with them the concrete in contact, since the plunger 5 at the end of the working stroke just before the Terminal point of the cover 8 is.
Die im herzustellenden Hohlbalken einzubauende Stahlbewehrung wird — wie oben bereits erwähnt — durch den Preßkolben 5 in die Schal·.,r.£ 3 geführt und infolge der Umklammerung des verdichten Betons beim Arbeitshub des Preßkolbens 5 mitgenommen.The steel reinforcement to be installed in the hollow beam is - as already mentioned above - through the plunger 5 into the shell ·., r. £ 3 and as a result of the clasping of the compacted concrete taken during the working stroke of the plunger 5.
Sobald der aus der Schalung 3 austretende Balken die vorgegebene Länge hat, fährt sein Vorderende an einen in entsprechendem Abstand hinter der Schalung 3 angeordneten Fühler IO an, der das Ablängen des Balkens mittels einer im vorliegenden Zusammenhang nicht wesentlichen und daher nicht näher beschriebenen Ablängeinrichtung auslöstAs soon as the beam emerging from the formwork 3 the has a predetermined length, its front end moves to a distance behind the formwork 3 arranged sensor IO, which the cutting to length of the beam by means of a in the present context triggers not essential and therefore not described in detail cutting device
