Line Element Lead-Through

Abstract

In order to produce a line element lead-through that is resistant to fire and flue gas for simple installation into one or more paneled drywalls, whereby the line element lead-through can be used in a matching component opening and is also sealed against fire and flue gas when empty, a line element lead-through is suggested with a molded element closed on at least one side of an elastically deformable intumescent material as a sleeve, especially formed as a truncated cone or a cylinder, with the criterion that the opening cross section of the sleeve corresponds to maximum 60% of the cross section of the component pass-through.

1 . A line element lead-through sealed against fire and flue gas for component openings, said line element lead-though including:
 a molded element designed as a sleeve of an elastic deformable intumescent material that is closed on at least one side with the characteristic that the opening cross section of the sleeve corresponds to maximum 60% of the cross section of the component opening.   
     
     
         2 . A line element lead-through according to  claim 1 , wherein the molded element is designed in one piece from intumescent material. 
     
     
         3 . A line element lead-through according to  claim 1 , wherein the molded element is provided on its face surface with a flange-like edging that points radially outward. 
     
     
         4 . A line element lead-through according to  claim 1 , wherein the molded element is closed at its cover surface in order to form a seal. 
     
     
         5 . A line element lead-through according to  claim 4 , wherein the material of the seal is thinner, at least in some areas, than the rest of the molded element. 
     
     
         6 . A line element lead-through according to  claim 4 , wherein the seal is designed as a membrane. 
     
     
         7 . A line element lead-through according to  claim 1 , wherein the wall thickness of the molded element is 5 to 20 mm. 
     
     
         8 . A line element lead-through according to  claim 5 , wherein the wall thickness of the seal that is thinner at least in some areas is 2 to 8 mm. 
     
     
         9 . A line element lead-through according to  claim 5 , wherein the thinner areas of the seal also have specified breaking points. 
     
     
         10 . A line element lead-through according to  claim 9 , wherein the specified breaking points have a wall thickness from 1 to 4 mm. 
     
     
         11 . A line element lead-through according to  claim 1 , wherein the molded element is designed as a truncated cone. 
     
     
         12 . A line element lead-through according to  claim 1 , wherein the molded element is designed as a cylinder. 
     
     
         13 . A line element lead-through according to  claim 12 , wherein on its outside, the molded element has at least one bead running radially around the outside that is arranged at a distance from the flange-like edging that points radially outward. 
     
     
         14 . A line element lead-through according to  claim 13 , wherein the distance between the bead and the flange-like edging is one of 12.5 mm, 16 mm, and a multiple of 12.5 mm or 16 mm. 
     
     
         15 . A line element lead-through according to  claim 13 , wherein the bead has a thickness of 4 to 6 mm in axial direction. 
     
     
         16 . A line element lead-through according to  claim 13 , wherein the bead has a thickness in radial direction of 2 to 4 mm. 
     
     
         17 . A line element lead-through according to  claim 1 , wherein the molded element is made of polyurethane foam with intumescence capability.
