Die Erfindung bezieht sich auf solche Formen zur Herstellung von Betonträgern, welche
aus mehreren in geradliniger Flucht hintereinander angebrachten zangenförmigen Klemmbackenpaaren
bestehen, deren Schenkel sämtlich durch ein Formblech verbunden sind, so daß beim Schließen der Backenpaare, was für
alle gleichzeitig geschieht, zwischen den Formblechen ein Raum verbleibt, welcher dem Querschnitt
des herzustellenden Trägers entspricht und mit dem Beton gefüllt wird. Die Form gemäß der Erfindung unterscheidet sich von
den erwähnten bekannten Formvorrichtungen dadurch, daß eines der Zangenpaare als
Nürnberger Schere ausgebildet ist, um eine große, für die Bewegung der Formteile günstige
Übersetzung zu erzielen.
Auf der Zeichnung stellt
Fig. ι eine Stirnansicht der Form im geschlossenen undThe invention relates to such forms for the production of concrete girders, which consist of several pairs of pliers-shaped clamping jaws mounted in a straight line one behind the other, the legs of which are all connected by a shaped sheet, so that when closing the jaw pairs, which happens for all of them at the same time, between the shaped sheets Space remains which corresponds to the cross-section of the beam to be produced and which is filled with the concrete. The mold according to the invention differs from the known molding devices mentioned in that one of the pairs of tongs is designed as Nuremberg scissors in order to achieve a large translation which is favorable for the movement of the molded parts.
On the drawing represents
Fig. Ι a front view of the form in the closed and
Fig. 2 eine solche im offenen Zustande der Form dar.Fig. 2 shows such in the open state of the mold.
Zwei Böcke 1 sind oben durch die Welle 3 verbunden, und das so gebildete Gestell ist mit Rädern 2 auf den Schienen 4 fahrbar. Je nach der Länge des herzustellenden Balkens oder Trägers sind entweder nur auf den beiden Enden der Welle 3 je ein Paar doppelarmige Hebel 36, 37 angebracht, oder es sind bei großer Länge zwischen diesen Endzangen noch weitere Zangen vorhanden. An die Enden der Hebelarme 37 sind durch Zapfen 38 wiederum Arme 39 angelenkt, welche durch einen Zapfen 40 verbunden sind und über letzteren hinaus sich als Handhebel 41 fortsetzen. Von jedem unteren, sich kreuzenden Hebelpaar 36, 37 ist der eine Hebel fest auf der Welle 3 aufgekeilt, der andere lose aufgesetzt; an den Schenkeln 36 sind unten die Formblechbacken 6, 7 befestigt.Two trestles 1 are connected at the top by the shaft 3, and the frame thus formed is with wheels 2 on the rails 4 mobile. Depending on the length of the beam to be made or carriers are either only on the two ends of the shaft 3 a pair of double-armed Lever 36, 37 attached, or there are long lengths between these end pliers more pliers available. At the ends of the lever arms 37 arms 39 are in turn articulated by pins 38, which through a pin 40 are connected and continue as a hand lever 41 beyond the latter. Of each lower, crossing pair of levers 36, 37, one lever is firmly wedged onto the shaft 3, the other loosely attached; the shaped sheet metal jaws 6, 7 are attached to the legs 36 at the bottom.
Zur Herstellung der Zementbetonkörper wird damit begonnen, daß man senkrecht unter der Welle 3 den Fußteil des Betonkörpers, nötigenfalls unter Verwendung seitlicher Formlatten, aufstampft, alsdann die Form durch Zusammenziehen der Griffe 41 schließt und nun den Formraum völlig füllt. Nach begonnenem Abbinden des Betons kann die Form geöffnet, auf den Schienen weitergefahren und der Betonkörper dem völligen Erhärten überlassen werden. Wie ersichtlich ist, bietet die Nürnberger Schere auch noch den Vorteil, daß zur Bewegung der Formbacken nur eine einzige Welle 3 erforderlich wird, während bei den bisher benutzten derartigen Formen beide Backen besondere Antriebe haben mußten.To produce the cement-concrete body is begun that one vertically under of the shaft 3 the foot part of the concrete body, if necessary using lateral form slats, stamps, then the mold closes by pulling together the handles 41 and now completely fills the mold space. After the concrete has started to set, the mold can be opened and continued on the rails and the concrete body can be left to harden completely. As can be seen, offers the Nuremberg scissors also have the advantage that they only move the mold jaws a single shaft 3 is required, while in the forms of this type previously used both jaws had to have special drives.
