FIRE PROTECTION CONSTRUCTION OF COMPARTMENT THROUGH-HOLE
PROBLEM TO BE SOLVED: To provide a fire protection construction of a compartment through-hole capable of easily performing fireproof treatment of a through-hole of a compartment body, and capable of securely preventing fire from propagating through the through-hole of the compartment body.SOLUTION: A fire protection construction 1 of a compartment through-hole includes a compartment body 2 and a foam sheet 3. The compartment body 2 has a through-hole 4 into which a wiring 5 is inserted. The foam sheet 3 has thermal expansion property, is wound around the periphery of the wiring 5 inserted into the through-hole 4, is arranged between the outer peripheral surface of the wiring 5 and the inner peripheral surface of the through-hole 4.SELECTED DRAWING: Figure 1
【課題】区画体の貫通孔の耐火処理を容易に実現可能であるとともに、区画体の貫通孔を通じて火災が伝搬することを確実に防止できる区画貫通孔の防火構造を提供する。【解決手段】本発明の区画貫通孔の防火構造１は、区画体２と、発泡シート３とを備える。区画体２は、貫通孔４を有し、貫通孔４には配線５が内挿される。発泡シート３は、熱膨張性を有しており、貫通孔４に内挿された配線５の周囲に巻き付けられて、配線５の外周面と貫通孔４の内周面との間に配置される。【選択図】図１
