Device for the positioning and retention of a tension member within a profile of a vertical casting formwork panel

Abstract

A device for the positioning and retention of a tension member within a profile of a formwork panel. The device comprises a first tubular body adapted to be inserted within a through hole provided on the profile of the formwork panel, the first body having a wider abutment portion arranged at one of its ends, the wider portion being adapted to be in contact with the surface of the formwork panel that is directed toward the outside of the formwork.

         21 . A device for the positioning and retention of a tension member within a profile of a formwork panel, comprising a first tubular body adapted to be inserted within a through hole provided on said profile of said formwork panel, said first body having a wider abutment portion arranged at one of ends thereof, said wider portion being configured to be in contact with a surface of said formwork panel that is directed toward an outside of said formwork. 
     
     
         22 . The device according to  claim 21 , wherein said wider portion has a D-shaped profile of a perimetric edge. 
     
     
         23 . The device according to  claim 21 , wherein said wider portion has a step-like shape, considering a direction of an axis of extension of said first tubular body. 
     
     
         24 . The device according to  claim 21 , wherein said first tubular body is preferably made of metallic material. 
     
     
         25 . The device according to  claim 21 , further comprising a second tubular body, adapted to be inserted at least partially in said first tubular body. 
     
     
         26 . The device according to  claim 25 , wherein said second tubular body is externally tapered and has a through hole. 
     
     
         27 . The device according to  claim 26 , wherein said through hole of said second body has a frustum-like shape with a cross-section having a smaller circumference arranged at an end of said wider portion that is directed toward the outside of said formwork. 
     
     
         28 . The device according to  claim 25 , wherein said second tubular body has two wider end portions and a plurality of annular protrusions between said two wider end portions. 
     
     
         29 . The device according to  claim 25 , wherein said second tubular body is preferably made of plastic material. 
     
     
         30 . The device according to  claim 25 , wherein said second tubular body is fully inserted in said first tubular body and said first tubular body and said second tubular body have the same length. 
     
     
         31 . A device for the positioning and retention of a tension member within a profile of a formwork panel, comprising:
 a first tubular body, adapted to be inserted within a through hole provided in said profile of said formwork panel,   a second body having a substantially toroidal profile inserted within said first tubular body.   
     
     
         32 . The device according to  claim 31 , wherein said first tubular body has a hole which is coaxial to a hole of said second body. 
     
     
         33 . The device according to  claim 31 , wherein said second body is made of plasticsl. 
     
     
         34 . The device according to  claim 31 , wherein said second body is arranged at/proximate to the end of said first tubular body that protrudes from said profile in the configuration for use of said device. 
     
     
         35 . The device according to  claim 25 , wherein said second body has, in the following order, considering an axis of extension of its hole:
 a first substantially disk-like portion, which is adapted to be leveled uniformly with said end of said first body,   a second annular portion with an outside diameter that is larger than an outside diameter of said first tubular portion,   a third annular portion, which in turn has:   an outside diameter that is smaller than an outside diameter of said second annular portion and is substantially equal to an outside diameter of said first tubular portion,   an inside diameter that is substantially equal to an inside diameter of said second annular portion and is such as to produce, with the perimetric wall of said hole of said first tubular body, a uniformly leveled surface.   
     
     
         36 . The device according to  claim 31 , wherein said first tubular body has an annular seat for accommodating said second annular portion of said second body proximate to said end. 
     
     
         37 . The device according to  claim 32 , wherein said hole of said first tubular body has a frustum-like shape with a cross-section having a smaller circumference located proximate to said end. 
     
     
         38 . The device according to  claim 32 , wherein said first tubular body has a wider portion arranged at said end. 
     
     
         39 . The device according to  claim 38 , wherein said wider portion has a D-shaped profile of the perimetric edge and a step-like shape, considering the direction of the axis of extension of said first body. 
     
     
         40 . The device according to  claim 31 , wherein said first tubular body has a portion with a reduced cross-section arranged at said end.
