Document Type and Number:
Japanese Patent JP7176728
Kind Code:
B2
Abstract:
To provide a thermally expandable member and a fireproof structure facilitating formation of an expansion body at a predetermined position.SOLUTION: A thermally expandable member 11 is used for suppressing the spread of a fire through a through-hole of a partition part through which a pipe body is inserted. The thermally expandable member 11 has a thermal expansion material 12 thermally expanded by heat at the time of spreading fire, and a bag 13 storing the thermal expansion material 12.
