摘要：<p>PROBLEM TO BE SOLVED: To provide a through-hole fireproof measure material capable of effectively decreasing a reduction rate of fireproof performance before and after a fire, and a through-hole fireproof measure structure.SOLUTION: A through-hole fireproof measure material T is loaded into a gap between an inner peripheral surface of a through-hole H formed in a partition body Y and an outer surface of an insertion body P inserted therethrough, or arranged on the outer surface side of the partition body Y corresponding to the gap. The through-hole fireproof measure material T is configured to have a multilayered structure that comprises an incombustible material layer 1 having flexibility and incombustibility, and a fire-resistant and thermally-expandable material layer 2 having flexibility, fire resistance and thermal expandability.</p>
