Line feed-through for feeding a line through a building component

Abstract

A line feed-Through for feeding a line through a building component can include one or more sealing arrangements for feeding the line through, wherein the one or more sealing arrangements have at least two sealing structures lying opposite each other, wherein at least one first of the sealing structures has an arrangement of elongate fins adjacent to each other, the protruding ends of which lie against a second of the sealing structures and thus seal the passage region.

1 : A line penetration for routing a line through a building structure part, comprising: one or more sealing arrangements for routing of the line,
 wherein the one or more sealing arrangements have at least two sealing structures situated opposite one another,   wherein at least one first of the sealing structures is provided with an arrangement of elongated lamellas adjacent to one another, the protruding ends of which bear on a second of the sealing structures and in this way seal the passage region.   
     
     
         2 : The line penetration according to  claim 1 , wherein the first and the second sealing structures of the sealing arrangement are provided respectively with an arrangement of elongated lamellas adjacent to one another, the protruding ends of which bear on one another. 
     
     
         3 : The line penetration according to  claim 2 , wherein the lengths of the adjacent lamellas of the first and of the second sealing structure may respectively vary, wherein the lamellas of the first and of the second sealing structures mesh with one another in the manner of a comb. 
     
     
         4 : The line penetration according to  claim 1 , wherein the second sealing structure has a flexible sealing element of an elastic material with a contact face on which the protruding ends of the lamellas of the first sealing structure bear. 
     
     
         5 : The line penetration according to  claim 4 , wherein the elastically deformable material of the sealing element and the elastic material of the lamellas as well as their geometric dimensioning may be chosen such that, when the line is routed through, these are forced by approximately half of their cross section into the elastically deformable material of the sealing element. 
     
     
         6 : The line penetration according to  claim 1 , wherein the first and/or the second sealing structure contains an intumescent material. 
     
     
         7 : The line penetration according to  claim 1 , wherein at least the first sealing structure has flexible bristles as lamellas, wherein the bristles are disposed in several rows, in order to form a brush structure, wherein the bristles of adjacent rows touch one another. 
     
     
         8 : The line penetration according to  claim 1 , wherein the lamellas of at least the first sealing structure have stiffness that decreases in the direction of extension toward the protruding ends. 
     
     
         9 : A line arrangement, comprising: having a penetration according to  claim 1  and a penetrating line, wherein the line is received in the passage region between the first and second sealing structures, so that both the first and second sealing structures are deformed. 
     
     
         10 : The line arrangement according to  claim 9 , wherein at least the lamellas have a width in arrangement direction that is smaller than the width of the penetrating line, wherein the width of the penetrating line is 5 times larger than the width of the lamellas. 
     
     
         11 : A method for sealing against fire gas and/or smoke in a building structure part, said method comprising:
 positioning the line penetration for routing a line through a building structure part according to  claim 1  in the building structure part.
