Line Element Lead-Through with Support Structure

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. Embedded within the molded element is a support structure.

1 . A line element lead-through sealed against fire and flue gas for component openings, said line element lead-though including:
 a molded element configured 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, wherein embedded within the molded element is a support structure.   
     
     
         2 . The line element lead-through according to  claim 1 , wherein the support structure includes a grid structure that is formed of at least glass fibers. 
     
     
         3 . The line element lead-through according to  claim 1 , wherein the support structure includes a fabric or a mat. 
     
     
         4 . The line element lead-through according to  claim 1 , wherein the support structure is completely embedded in a foamed body of the molded element. 
     
     
         5 . The line element lead-through according to  claim 1 , wherein the support structure is flexible. 
     
     
         6 . The line element lead-through according to  claim 1 , wherein the support structure is rigid. 
     
     
         7 . The line element lead-through according to  claim 1 , wherein the support structure is completely embedded in the molded element. 
     
     
         8 . The line element lead-through according to  claim 1 , wherein, when a first portion of the molded element is burned into an ash crust, the support structure structurally connects the ash crust to a second portion of the molded element that is unburned. 
     
     
         9 . The line element lead-through according to  claim 1 , wherein the support structure restrains an expansion of the elastic deformable intumescent material. 
     
     
         10 . The line element lead-through according to  claim 1 , wherein the molded element is configured as one piece from the elastic deformable intumescent material. 
     
     
         11 . The line element lead-through according to  claim 1 , wherein the molded element is configured as a truncated cone, and wherein the support structure is configured as the truncated cone. 
     
     
         12 . The line element lead-through according to  claim 1 , wherein the molded element is configured as a cylinder, and wherein the support structure is configured as the cylinder. 
     
     
         13 . The line element lead-through according to  claim 1 , wherein the molded element is made of at least a polyurethane foam with intumescence capability. 
     
     
         14 . The 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. 
     
     
         15 . The line element lead-through according to  claim 14 , wherein the support structure does not extend into the flange-like edging. 
     
     
         16 . The line element lead-through according to  claim 1 , wherein the molded element is closed at its cover surface in order to form a seal. 
     
     
         17 . The line element lead-through according to  claim 16 , wherein the material of the seal is thinner, at least in some areas, than the rest of the molded element. 
     
     
         18 . The line element lead-through according to  claim 17 , wherein the thinner areas of the seal also have specified breaking points. 
     
     
         19 . The line element lead-through according to  claim 16 , wherein the seal is configured as a membrane.
