  Zur   Armierung   von   Säulen   ans   umschnürtem   Beton dienendes Werkstück. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Bei der Ausführungsform gemäss der Fig. 1 und 2 kommen zwei   Umsehnürungen   zur Anwendung, von welchen die eine e sich aussen in die Rillen des Wellbleche einlegt und zur Befestigung der Well- 
 EMI2.1 
 bildenden Lamellen anschmiegt und zwischen diesen gradlinig verläuft. Die Anordnung der inneren Umschnürung erfolgt   zweckmässig   unter hoher maschineller Spannung des Drahtes. 



   Das Wellblech mit den in den Aussenrillen eingelegten Drahteinlagen dient gleichzeitig als 
 EMI2.2 
 beim Betonieren die Luft entweichen kann und die Wellenberge des Bleches mit Beton vollkommen ausgefüllt werden können. Durch diese Löcher wird auch das Austrocknen des Betons erleichtert. Die Löcher können im Wellblech durch Aufstossen gebildet werden, so dass die scharfen, aufgestellten Lochränder in ebenfalls bekannter Weise gemäss Fig. 5 als Putzträger dienen. Um die axiale Einstellung mehrerer Säulen übereinander zu gewährleisten, weisen die Flanschen   b Ansätze lt auf,-welche   in entsprechend gestaltete Ausnehmungen i der   daraufgestellten   Säule eingreifen. Die Endausbildung k der   Säule weist nach   oben offene Schlitze   I   auf.

   Dies hat gegenüber den bekannten Säulenköpfen mit seitlichen Öffnungen den Vorteil, dass die Armierungseisen für die Balken von oben eingelegt werden können. 



   Wie aus den Fig. 1 und 3 der Zeichnung ersichtlich ist, weist der Eisenkern an seinem oberen Ende 
 EMI2.3 
 dem Eisenkern und der Umschnürung, dadurch gekennzeichnet, dass das Werkstück auch den Säulenkopf und die Schalung mit dem Putzträger aufweist.

  Workpiece used to reinforce columns on the concrete.
 EMI1.1
 

 <Desc / Clms Page number 2>

 



   In the embodiment according to FIGS. 1 and 2, two Umsehnürungen are used, one of which is inserted outside into the grooves of the corrugated sheet and for fastening the corrugated sheet.

 forming lamellas and runs straight between them. The arrangement of the inner constriction is expediently carried out under high mechanical tension on the wire.



   The corrugated iron with the wire inlays inserted in the outer grooves also serves as a
 EMI2.2
 the air can escape during concreting and the corrugation peaks of the sheet can be completely filled with concrete. These holes also make it easier for the concrete to dry out. The holes can be formed in the corrugated sheet metal by pushing it open, so that the sharp, raised hole edges serve as a plaster base in a likewise known manner according to FIG. In order to ensure the axial adjustment of several columns on top of one another, the flanges b have approaches lt, -which engage in correspondingly designed recesses i of the column placed thereon. The end formation k of the column has slots I open at the top.

   This has the advantage over the known column heads with lateral openings that the reinforcing irons for the beams can be inserted from above.



   As can be seen from FIGS. 1 and 3 of the drawing, the iron core has at its upper end
 EMI2.3
 the iron core and the constriction, characterized in that the workpiece also has the column head and the formwork with the plaster base.

Claims

2. Workpiece for concrete columns according to claim 1, characterized in that to secure the EMI2.4 be pushed onto the lamellae (a) of the iron core (Fig. 3).

3. Embodiment of the workpiece according to claim 1, characterized in that a sheet metal strip (e) is wound up in screw windings as a Sehalungträger on the iron core (a), which also serves as a constriction (Fig. 6).

4. embodiment of the workpiece according to claim 3, characterized in that corrugated iron strips are wound up in a spiral as formwork and plaster base. o. Embodiment of the workpiece according to claim 4, characterized in that the corrugated sheet metal sheets (d) used as formwork are arranged in such a way that their grooves run along helical lines.

6. Workpiece according to claim 1, characterized in that for fastening the corrugated sheet to the iron core in the grooves of the corrugated sheet according to claim 4 or 5, a wire constriction (e) is inserted from the outside.

7. Embodiment of the workpiece according to claim 6, characterized in that a second Umsehnürung (f) is arranged in the interior of the wave crests, which clings to the lamellae forming the iron core with tension and runs in a straight line between them (Fig. 2).

8. Workpiece according to claim 1, characterized in that the iron core has no protruding parts in order to prevent the separately completed constrictions and the formwork being pushed on. EMI2.5 9. Workpiece according to claim 8, characterized in that the flanges provided at the ends of the iron core have lugs ü which engage in recesses (i) of the flanges of the column placed thereon.

10. Workpiece according to claim 8 or 9, characterized in that the end formation cast from one piece with the iron core (a) (k) has upwardly open slots (I) to allow the reinforcement iron for the bars to be pushed in from above enable.
