Fastening element

Abstract

A fastening element, which is used in particular in mines and/or tunnel construction, includes an anchoring tube ( 2 ), a squeezable-out, one-or multicomponent chemical mass contained in a foil bag ( 5;25 ) arranged in the anchoring tube ( 2;2 ) between spaced from each other, first stop ( 7,27 ) and second stop ( 9 ), and at least one pressure application element ( 14 ) arranged between the first stop ( 7,27 ) and/or the second stop ( 9 ) and a respective axial end region ( 11,12;31 ) of the foil bag ( 5;25 ) for applying pressure to the foil bag ( 5;25 ) in a shelf condition of the fastening element ( 1;21 )

1 . A fastening element, comprising an anchoring tube ( 2 ; 22 ) having a first end ( 3 ) and a second end ( 4 ); a squeezable-out, one-or multicomponent chemical mass contained in a foil bag ( 5 ; 25 ) arranged in the anchoring tube ( 2 ; 22 ) between spaced from each other, first stop ( 7 , 27 ) and second stop ( 9 ); and at least one pressure application element ( 14 ) arranged between one of the first stop ( 7 , 27 ) and the second stop ( 9 ) and a respective axial end region ( 11 , 12 ; 31 ) of the foil bag ( 5 ; 25 ) for applying pressure to the foil bag ( 5 ; 25 ) in a shelf condition of the fastening element ( 1 ; 21 ).  
   
   
       2 . A fastening element according to  claim 1 , wherein the at least one pressure application element ( 14 ) is formed as a spring element.  
   
   
       3 . A fastening element according  claim 2 , wherein the spring element is formed as a helical spring ( 15 ).  
   
   
       4 . A fastening element according to  claim 1 , further comprising a drilling head ( 6 ) provided at the first end ( 3 ) of the anchoring tube ( 2 ), wherein the first stop ( 7 ) is formed by a section of the drilling head ( 6 ).  
   
   
       5 . A fastening element according to  claim 1 , wherein the first stop ( 27 ) is formed by mixing means ( 36 ) provided at the first end ( 3 ) of the anchoring tube ( 2 ).  
   
   
       6 . A fastening element according to  claim 1 , wherein the second stop ( 9 ) is formed by a centering element ( 8 ) provided at the second end ( 4 ) of the anchoring tube ( 2 ).  
   
   
       7 . A fastening element according to  claim 1 , wherein the at least one pressure application element ( 14 ) is provided between the second stop ( 9 ) and the adjacent thereto, end region ( 12 ) of the foil bag ( 5 ; 25 ).
