Description

  

      Verspannvorrichtung    für     Beton-Verschalungen.       Die Erfindung betrifft eine     Verspannvor-          rielitung    für     Beton-Verschalungen,    -welche  sieh dadurch kennzeichnet,     dass    eine zum  Durchstecken durch die     Selialwände    be  stimmte Spannschraube mit einer lose auf  geschobenen, aussen schwach     konisehen    Hülse  versehen ist, welche zur Distanzierung der  Schalwände dient und nach dem Ausschalen  durch Schlag auf ihr dünneres Ende aus dem  Beton     herausstossbar    ist, so     dass    sie immer  fort wieder verwendet werden kann.  



  Bei dem in der Zeichnung darge  stellten Ausführungsbeispiel des     Eriin-          dungsgegenstandes    ist a eine durch die  Schalwände<B>_A</B>     durellgesteckte        Spannseliraube     mit Muttern a' an ihren Enden,     wällrend   <B>b</B>  eine auf die Schraube lose aufgeschobene  Hülse ist, die aussen glatt ist und von einem  Ende nach dem andern zu aussen schwach  konisch verläuft.

   Die Hülse<B>b</B> dient zur Di  stanzierung der Schalwände<B>_A.</B> Nach dem       Ausse,halen    wird sie     diuch        Sohlag    auf ihr    dünneres Ende aus dem Beton herausgesto  ssen, was ihre     Konizität'    leicht     zulässt.    Da  durch kann die Hülse<B>b</B> immerfort wieder  verwendet werden, während sonst die<B>Di-</B>  stanzhülsen im Beton stechen     -elassen    wer  den.



      Bracing device for concrete formwork. The invention relates to a bracing device for concrete cladding, which is characterized in that a clamping screw intended to be pushed through the selial walls is provided with a loosely pushed, slightly conical sleeve on the outside, which serves to distance the shuttering walls and after Stripping can be pushed out of the concrete by hitting its thinner end, so that it can be used again and again.



  In the exemplary embodiment of the subject matter of the invention shown in the drawing, a is a tensioning hood with nuts a 'at its ends, which is inserted through the formwork walls, while one is loose on the screw is pushed-on sleeve, which is smooth on the outside and runs slightly conical from one end to the other to the outside.

   The sleeve <B> b </B> is used to separate the formwork walls <B> _A. </B> After the outside, the bottom layer is pushed out of the concrete on its thinner end, which allows its conicity to be slightly . This means that the <B> b </B> sleeve can be used again and again, while the <B> Di </B> punch sleeves are otherwise left to pierce the concrete.
