Description

  

   <Desc/Clms Page number 1> 
 



  Blechsehalung aus einzelnen im Querschnitt   lireisbogenfürmigen   Teilen zur Herstellung stehend gegossener, kegeliger Betonleitungsmaste kreisrunden Querschnittes. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 in einem oder mehreren Ringen verankert worden ist, werden die Abschlüsse 1 c von den Einfüll- öffnungen abgenommen und der Mast absatzweise in genannter Art betoniert. Nach dem Abbinden des Betons werden die Anker entfernt und die Schalungsteile 1,   1',   1" durch einfache Lösung der Keilverschlüsse 2 abgenommen. Der fertige Mast zeigt eine glatte Oberfläche, ohne dass irgendeine Nachbearbeitung notwendig wäre.

   Gegenüber dem raschen Verschleiss der sonst üblichen Holzschalungen sind die Blechschalungen praktisch unbegrenzt oft wieder verwendbar und zeichnen sich durch geringes Gewicht, einfache Handhabung und leichte Lagerhaltung zufolge geringen Raumbedarfes aus. Die kegelige Ausbildung der Schalung bietet den Vorteil, ganze Schalungsserien vom kleinsten bis zum grössten vorkommenden Querschnitt durchlaufend entwickeln zu können und nach Bedarf diejenigen Teile herauszugreifen, welche nach Querschnitt und Länge den an den Mast gestellten Ansprüchen genügen. 



   Wie aus dem Vorbeschriebenen hervorgeht, sind Schalungen zur Herstellung stehend gegossener Betonleitungsmaste grossen Beanspruchungen ausgesetzt. Die bisher bekannten Blechschalungen tragen diesem Umstande zu wenig oder gar nicht Rechnung. Erfindungsgemäss wirken die Flanschen 1 a und 1 b als Versteifungsrippen in Längs-und Querrichtung. Die Ringflanschen 1 b in Verbindung mit den Keilbolzen 2 sind insbesondere befähigt, axiale Zugkräfte oder Biegungsmomente, wie sie sowohl beim Aufstellen der Schalung als auch durch Windangriffe auf die aufrecht stehende Schalung auftreten, zu übernehmen. 



   Für die Anbringung von Steigeisen zum Besteigen des Mastes zwecks Einbringung des Betons besitzen die Schalungsteile mindestens längs einer Kegelerzeugenden Ausnehmungen, durch welche die Steigeisen vor der Aufstellung der liegend hergestellten Mastschalung eingesetzt und sodann mitbetoniert werden. 



   PATENT-ANSPRÜCHE :
1. Blechschalung aus einzelnen im Querschnitt kreisbogenförmigen Teilen zur Herstellung stehend gegossener, kegeliger Betonleitungsmaste kreisrunden Querschnittes, gekennzeichnet durch an allen vier Seiten mit Flanschen   (1   a, 1 b) versehene, im Querschnitt viertelkreisbogenförmige 
 EMI2.1 
 zu   kegelstumpfförmigen Rohrschüssen   und durch gleiche Verbindungsmittel an den Ringflanschen   (1   b) zur vollen Schalung beliebiger Höhe verbunden werden, wobei zwecks absatzweiser Betonierung in jedem Rohrschuss ein allseits geflanschter Schalungsteil   (1   e) als Abschluss der seitlichen Einfüllöffnung für den Beton vorgesehen ist.

  Sheet metal cladding made of individual parts shaped like an arched ice in cross section for the production of upright cast, conical concrete masts with a circular cross section.
 EMI1.1
 

 <Desc / Clms Page number 2>

 has been anchored in one or more rings, the terminations 1c are removed from the filling openings and the mast is concreted in sections in the manner mentioned. After the concrete has set, the anchors are removed and the formwork parts 1, 1 ', 1 "are removed by simply loosening the wedge locks 2. The finished mast has a smooth surface without any post-processing being necessary.

   Compared to the rapid wear and tear of the otherwise customary wooden formwork, the sheet metal formwork can be reused practically unlimited times and is characterized by its low weight, simple handling and easy storage due to the small space requirement. The conical design of the formwork offers the advantage of being able to continuously develop entire series of formwork from the smallest to the largest occurring cross-section and, if necessary, to pick out those parts that meet the demands placed on the mast in terms of cross-section and length.



   As can be seen from the above, formwork for the production of upright cast concrete line masts is exposed to great stresses. The previously known sheet metal formwork takes this circumstance too little or not at all into account. According to the invention, the flanges 1 a and 1 b act as stiffening ribs in the longitudinal and transverse directions. The ring flanges 1 b in conjunction with the wedge bolts 2 are particularly capable of absorbing axial tensile forces or bending moments, such as those that occur both when setting up the formwork and when the formwork is exposed to wind on the upright formwork.



   For the attachment of crampons to climb the mast for the purpose of introducing the concrete, the formwork parts have at least one cone-generating recesses through which the crampons are inserted and then concreted before the erection of the mast formwork.



   PATENT CLAIMS:
1. Sheet metal formwork from individual parts with a circular cross-section for the production of upright cast, conical concrete masts with a circular cross-section, characterized by having flanges (1 a, 1 b) on all four sides and with a quarter-circle arc in cross-section
 EMI2.1
 to form frustoconical pipe sections and using the same connecting means on the ring flanges (1 b) to form full formwork of any height, with a formwork part (1 e) flanged on all sides to close off the lateral filling opening for the concrete in each pipe section for the purpose of intermittent concreting.
