Leadthrough system

Abstract

A leadthrough system for a constructional component, such as a deck or a wall, includes a frame ( 11 ) having at least two frame sections ( 12, 13 ) defining together a channel ( 31 ), sleeve sections ( 14, 15 ) surrounding the channel ( 31 ), with at least one sleeve section ( 14 ) tapering from one of its ends ( 18 ) to another of its ends ( 19 ), and at least one insertion member ( 20, 41 ) having a conical section ( 21 ) corresponding to a tapering contour of the at least one sleeve section ( 14 ).

1 . A leadthrough system for a constructional component ( 30 ), comprising: 
 a frame ( 11 ) having at least two frame sections ( 12 ,  13 ) defining together a channel ( 31 ) and respective sleeve sections ( 14 ,  15 ) surrounding the channel ( 31 ), with at least one sleeve section ( 14 ) tapering from one end ( 18 ) of a respective frame section ( 12 ) to another end ( 19 ) of the respective frame section ( 12 ); and    at least one insertion member ( 20 ,  41 ) having a conical section ( 21 ) corresponding to a tapering contour of the at least one sleeve section ( 14 ).    
   
   
       2 . A leadthrough system according to  claim 1 , wherein the conical section ( 21 ) of the at least one insertion member ( 20 ,  41 ) has an outer surface ( 25 ) provided with a layer ( 26 ) of an intumescent material.  
   
   
       3 . A leadthrough system according to  claim 1 , comprising a plurality of insertion members ( 20 ) for completely closing the channel ( 31 ).  
   
   
       4 . A leadthrough system according to  claim 1 , wherein the at least one insertion member ( 20 ,  41 ) has at least one flange section ( 22 ) at an end thereof.  
   
   
       5 . A leadthrough system according to  claim 1 , wherein the at least one insertion member ( 20 ,  41 ) has an inner space ( 23 ) filled with an intumescent material.  
   
   
       6 . A leadthrough system according to  claim 1 , wherein the at least one insertion member ( 20 ,  41 ) has an inner space ( 23 ) filled with mineral constructional material.  
   
   
       7 . A leadthrough system according to  claim 1 , wherein the at least one insertion member ( 20 ) is provided with a handle ( 24 ).  
   
   
       8 . A leadthrough system according to  claim 1 , wherein the at least one insertion member ( 41 ) is provided with at least one preliminary formed leadthrough ( 42 ).
