Auf der Arbeitsfläche 15a steht der Schalungshalter 14. Dieser weist einen im wesentlichen horizontal verlaufenden ersten Träger 16 und einen im wesentlichen vertikal verlaufenden zweiten Träger 17 auf, der mit dem ersten Träger 16 durch ein Gelenk 18 verbunden ist und um dieses Gelenk herum verschwenkt werden kann. Der erste Träger 16 und der zweite Träger 17 bilden einen Winkel. An den Innenseiten dieses Winkels sind die Träger mit in Längsrichtung der Schalung verlaufenden U-Eisen 20 bzw. 21 versehen, in die Kanthölzer 22 bzw. 23 eingesetzt werden können, an welchen die Schalungsplatten 24,25 befestigt werden. Die Schalungsplatten 24 verlaufen somit parallel zu dem ersten Träger 16 und die Schalungsplatten 25 verlaufen parallel zu dem zweiten Träger 17. The formwork holder 14 stands on the working surface 15a. This has an essentially horizontal first carrier 16 and one essentially vertically extending second support 17 on the the first carrier 16 is connected by a joint 18 and can be pivoted around this joint.

Such a change in length causes a change in the angle that the beams 16 and form 17.

Der Träger 16 ruht auf höhenverstellbaren Stützen 30,31, die hier als Spindeln ausgebildet sind. Durch unterschiedliche Höheneinstellungen der Stützen kann die Neigung des Trägers 16 in Bezug auf die Arbeitsfläche 15a verändert werden. Vorzugsweise sind die Stützen 30,31 mit (nicht dargestellten) Rollen versehen, so daß die gesamte Schalung in Längsrichtung der Außenkappe 13 nach Art einer Gleitschalung verschoben werden kann.The carrier 16 rests on height-adjustable supports 30,31, which are designed here as spindles. By different height settings of the supports the inclination of the beam 16 with respect to the work surface 15a can be changed. Preferably, the Provide supports 30, 31 with rollers (not shown), so that the entire formwork in the longitudinal direction of the Outer cap 13 moved in the manner of a sliding formwork can be.

Der Schalungshalter 14 ist an dem Bauwerk 10 mit Zugorganen 32 verankert, die einerseits mit einer am Bauwerk befestigten Halterung 32a und andererseits mit einem an dem Träger 16 vorgesehenen Widerlager 32b verbunden sind. Die Zugorgane 32 verhindern, daß beim Betonieren der Außenkappe 13 die Schalung durch den Druck des Betons zurückweicht. Das Zugorgan 32 kann aus einem spannbaren Drahtseil oder einer spannbaren Stange bestehen. Wie Fig. 2 zeigt, ist das Zugorgan 32, das hier aus einer Stange besteht, mit einem Gelenkrohr 50 in den Halter 32a eingesetzt und mit einer Spannvorrichtung 51 am Widerlager 32b abgestützt. Das Widerlager 32b weist einen nach unten offenen Längsschlitz 52 auf, durch den das Zugorgan 32 hindurchgesteckt ist. Zum Lösen des Zugorgans kann die Spannvorrichtung 51 gelöst und dann das Zugorgan aus dem Lenkschlitz 52 herausgeschwenkt werden.The formwork holder 14 is on the structure 10 with tension members 32 anchored on the one hand with one on the structure attached bracket 32a and the other with one the abutment 32b provided to the carrier 16 are. The tension members 32 prevent that when concreting the outer cap 13 the formwork by the pressure of the concrete recedes.
