THROUGH HOLE FIRE PROTECTIVE MEMBER, THROUGH HOLE FIRE PROTECTIVE STRUCTURE USING THE MEMBER, AND CONSTRUCTION METHOD OF FIRE-PROTECTING THROUGH HOLE

摘要

PROBLEM TO BE SOLVED: To provide a through hole fire protective member having excellent construction efficiency while effectively suppressing the formation of a large non-filled space in the gap between the inner peripheral surface of a through hole and the outer surface of a long body.;SOLUTION: This through hole fire protective member is placed in the gap between the inner peripheral surface of the through hole formed in a compartment body and the outer surface of the long body inserted thereinto, or disposed on the outer surface side of the compartment body corresponding to the gap. Fireproof thermal expansion projection pieces 2 formed of a fireproof material having flexibility and thermal expansion property are disposed on a base member 1 with flexibility in the form of groups.;COPYRIGHT: (C)2008,JPO&INPIT
