<P>PROBLEM TO BE SOLVED: To provide a fireproof compartment through-part structure which can reduce the transfer of the heat of a fire or the like from one compartment of the structure where the fire occurs to the other compartment of the structure where the fire does not occur, and which is excellent in fire resistance and maintainability. <P>SOLUTION: The fireproof compartment through-part structure comprises: at least, metal piping inserted through a through-hole of the compartment provided in a partition part of the structure; a sealing material blocking a gap between the through-hole and the metal piping; a thermally expansible fire-resistant sheet installed on the outer face of the metal piping existing outside the through-hole; and a non-combustible heat insulating material installed around the metal piping via the thermally expansible fire-resistant sheet. The metal piping has a metal piping body and a synthetic resin heat insulating material layer installed on the outer face of the metal piping body. The non-combustible heat insulating material is installed in contact with the thermally expansible fire-resistant sheet and the outside surface of the compartment. <P>COPYRIGHT: (C)2013,JPO&INPIT |
