PROBLEM TO BE SOLVED: To provide a through-hole fire protection measure structure for developing a desired fireproof blocking function by maximally maintaining the state of winding a fireproof tape around the outer peripheral face on the end side of a fireproof sleeve and the outside face of a long body when moving force in the longitudinal direction works on the long body resulting from external force such as earthquake.SOLUTION: A fireproof tape 7 having an adhesive layer formed on the single side is wound around the outer peripheral face on the end side of a fireproof sleeve 4 passed through a through-hole of a fireproof structure and the outside face of a long body 3 inserted through the fireproof sleeve 4 to block an area between the inner peripheral face of the fireproof sleeve 4 and the outside face of the long body 3. Joint force between the fireproof tape 7 and the outside face of the long body 3 is smaller than joint force between the fireproof sleeve 7 and the outer peripheral face on the end side of the fireproof sleeve 4. |
