FIRE RESISTING SYSTEM AND METHOD FOR PROVIDING SUCH SYSTEM

摘要

Transit system (TS) for incorporation in a construction element (P) that divides two compartments (CI, CII) comprising a conduit (CS) through which at least one pipe (P) extends from one of the two compartments to the other of the two compartments and into which heat can be conducted, wherein a substantially- endless inner wall of the conduit defines an inner cross-sectional volume which is composed of a pipe-free part that is unoccupied by the at least one pipe and a pipe-occupied part that is occupied by the at least one pipe, the transit system further comprising a plurality of similar fire resistant and heat expandable rubber members (RM) with which the pipe-free part of the inner cross-sectional volume is filled up and which are distributed over that part, so that at least one of the pipes extending through the conduit is free from being coaxially surrounded by a single one of the rubber members .
