To provide a perforation fire-prevention measure member and a perforation fire-prevention measure structure which can effectively reduce a degradation rate in fire-prevention performance before and after fire.
The perforation fire-prevention measure member T is loaded in the clearance between the inner peripheral surface of a perforation H formed in a partition body Y and the outer surface of an insertion body P inserted in the perforation H. Alternatively, the perforation fire-prevention measure member T is arranged on the outer surface side of the partition body Y which corresponds to the clearance. The perforation fire-prevention measure member T is constructed of a double-layer structure which is provided with an incombustible material layer 1 and a fireproof thermal expansion material layer 2. The incombustible material layer 1 has flexibility and incombustibility, and the fireproof thermal expansion material layer 2 has flexibility, fire resistance, and thermal expansion performance.
