Anchoring element and method for mounting an anchor rail in a structural body of concrete

Abstract

An anchoring element for casting in concrete has an anchor rail having a plurality of anchor protrusions and a strip-shaped receptacle for mounting fastening elements. At least one retaining bracket is fixed to the anchor rail, which engages over the anchor rail perpendicularly to its longitudinal direction and by means of which the anchor rail can be fixed to a formwork component. At least one flange projecting laterally from the anchor rail is formed on the retaining bracket.

1 . An anchoring element for casting in concrete, comprising:
 an anchor rail ( 1 ) having a plurality of anchor protrusions ( 2 ),   a strip-shaped receptacle for mounting fastening elements,   at least one retaining bracket ( 20 ) fixed to the anchor rail ( 1 ), which retaining bracket ( 20 ) engages over the anchor rail ( 1 ) perpendicularly to a longitudinal direction of the anchor rail and by means of which the anchor rail ( 1 ) can be fixed to a formwork component ( 10 ), and   at least one flange ( 22 ) projecting laterally from the anchor rail ( 1 ) and formed on the retaining bracket ( 20 ),   wherein the at least one flange ( 22 ) is connected to a central section ( 21 ) of the retaining bracket ( 20 ) by means of a predetermined breaking point ( 24 ).   
     
     
         2 . The anchoring element according to  claim 1 , wherein the predetermined breaking point ( 24 ) is produced by a material weakening in the form of a reduction of a material cross-section. 
     
     
         3 . The anchoring element according to  claim 1 , wherein the at least one flange ( 22 ) projecting from the anchor rail ( 1 ) is formed by two flanges disposed on opposite sides of the retaining bracket ( 20 ). 
     
     
         4 . The anchoring element according to  claim 3 , wherein each flange ( 22 ) has a profiling on an upper surface for preventing slipping of the fixing element. 
     
     
         5 . The anchoring element according to  claim 1 , wherein the at least one retaining bracket ( 20 ) is fixed to the anchor rail ( 1 ) in a clamping or latching manner. 
     
     
         6 . The anchoring element according to  claim 1 , wherein a plurality of said at least one retaining brackets ( 20 ) are fixed to the anchor rail ( 1 ). 
     
     
         7 . The anchoring element according to  claim 1 , wherein the at least one retaining bracket ( 20 ) is made of plastic. 
     
     
         8 . The anchoring element according to  claim 3 , wherein each flange ( 22 ) has a thickness of less than 5 mm. 
     
     
         9 . A unit consisting of an anchoring element according to  claim 1  and a plate-shaped formwork component ( 10 ) to which the anchor rail ( 1 ) is fixed via the at least one retaining bracket ( 20 ). 
     
     
         10 . The unit according to  claim 9 , wherein the at least one retaining bracket ( 20 ) is fixed to the formwork component via at least one nail ( 11 ). 
     
     
         11 . The unit according to  claim 9 , wherein two anchor rails ( 1 ) are overlapped in an abutting area by said at least one retaining bracket ( 20 ) and fixed to the formwork component ( 10 ). 
     
     
         12 . A method for mounting an anchor rail ( 1 ) in a structural body of concrete, comprising the following steps:
 positioning the anchor rail ( 1 ) on a formwork component ( 10 );   arranging at least one retaining bracket ( 20 ) on the anchor rail ( 1 );   fixing the at least one retaining bracket ( 20 ) to the anchor rail ( 1 ) via at least one fixing element on the formwork component ( 10 );   casting the anchor rail ( 1 ) in concrete, and   removing the formwork component ( 1 ) with the at least one fixing element ( 11 ) from the anchor rail ( 1 ),   wherein at least one flange ( 22 ) of the retaining bracket ( 20 ) with the fixing element ( 11 ) is also removed during removal.   
     
     
         13 . The method according to  claim 12 , wherein the at least one fixing element ( 11 ) is designed as as a nail and is shot into the formwork component ( 10 ) via a nail gun. 
     
     
         14 . The method according to  claim 12 , wherein the flange ( 22 ) is removed at a predetermined breaking point ( 24 ) produced by a weakening of the materials in the form of a reduction of a material cross-section.
