Description
Die immer mehr zunehmende Anwendung von Gewölben, namentlich in Beton mit sehr verschiedenen Spannweiten und Busenhöhen, erfordern bei den bisherigen Holzlehrbögen und Gerüsten sehr viel und kostspieliges Material, welches nach einmaliger Anwendung fast unbrauchbar wird. Dies zu vermeiden, dienen meine verstellbaren Lehrbögen.The ever increasing use of vaults, especially in concrete with very different spans and bust heights, require the previous wooden teaching arcs and scaffolding very much and expensive material, which after a single use almost unusable will. My adjustable teaching sheets serve to avoid this.
Ein System von Stäben α, Fig. ι und 2, aus Eisen, oder Stahl, von geeignetem Querschnitt ist an den Enden, ähnlich der Nürnberger. Scheere, durch Bolzen b drehbar verbunden, so dafs sich dadurch Kreuze von verschiedener Form bilden lassen, wenn das System aus einander gezogen wird. Die äufsersten Enden des Systems haben im letzten Drehpunkt Haken g, welche beim Aufstellen der Bögen durch Anziehen der Ketten h nach aufsen greifen und sich auf die Widerlager T des Gewölbes oder Bogens auflegen.A system of bars α, Fig. Ι and 2, made of iron or steel, of suitable cross-section is at the ends, similar to that of Nuremberg. Scissors, rotatably connected by bolts b , so that crosses of different shapes can thereby be formed when the system is pulled apart. The outermost ends of the system have hooks g in the last fulcrum which, when the arches are set up, reach out by tightening the chains h and rest on the abutments T of the vault or arch.
Die oberen Bolzen b tragen Knaggen c von LJ - förmigem Querschnitt, in die sich ein Schmiegebrett d einlegt, welches dem aufgestellten Bogen die Form giebt, wenn die Enden desselben in die geschlossenen Endknaggen C1 C1 eingeschoben werden.The upper bolts b carry lugs c with an LJ -shaped cross-section, into which an attaching board d is inserted, which gives the bow its shape when its ends are pushed into the closed end lugs C 1 C 1 .
Die Spannung des Bogens wird bewirkt durch die Kette e, Fig. 1, oder die Schienen i, Fig. 2, je nachdem der Bogen flach oder überhöht ist.The tension of the bow is effected by the chain e, Fig. 1, or the rails i, Fig. 2, depending on whether the bow is flat or elevated.
Die Stabilität erhält der Bogen durch Ansetzen der Klemmschrauben f an allen Kreuzungsstellen der Stäbe. Zum Aufstellen des Bogens werden dieselben ohne das Schmiegebrett d nach der Schnürung aus einander gezogen, die Ketten e oder Schienen i an den unteren Enden der Stäbe α befestigt und die Klemmschrauben f an den Kreuzungsstellen festgeschraubt. Nun wird die Brettschmiege d in den einen geschlossenen Endknaggen C1 eingeschoben, über sämmtliche Knaggen c und durch den anderen Endknaggen C1 geführt.The arch is given its stability by attaching the clamping screws f at all crossing points of the bars. To set up the arch, the same are pulled apart after the lacing without the hanging board d , the chains e or rails i are attached to the lower ends of the bars α and the clamping screws f are screwed tight at the crossing points. Now the board bevel d is pushed into the one closed end claw C 1 , passed over all claws c and through the other end claw C 1 .
Die Lehrbögen werden dann derart auf die Widerlager gebracht, dafs ein Haken g, nach aufsen gelegt und mit der Kette h befestigt, auf das eine Widerlager gelegt wird; das andere Ende des Bogens wird über das Widerlager hinausgehoben, der zweite Hakenarm angezogen und mit der Kette befestigt, wodurch der Haken auf das zweite Widerlager übergreift; nun wird der Bogen gesenkt, bis er aufliegt.The teaching arcs are then placed on the abutment in such a way that a hook g is placed on the outside and fastened with the chain h , on which an abutment is placed; the other end of the arch is lifted over the abutment, the second hook arm is tightened and fastened with the chain, whereby the hook engages over the second abutment; now the bow is lowered until it rests.
Nach Aufstellen sämmtlicher Bögen wird auf die Schmiegebretter die Verschalung gelegt.After all the arches have been set up, the casing is placed on the boards.
Zum Entfernen der Lehrbögen werden die Ketten h gelöst und die Arme der Haken g nach aufsen gedrückt, wodurch sich die Haken von den Widerlagern abheben, so dafs die Bögen entfernt werden können.To remove the teaching arcs, the chains h are loosened and the arms of the hooks g are pressed outwards, whereby the hooks lift off the abutments so that the arcs can be removed.
