FIRE PREVENTION MEASURE STRUCTURE AND FIRE PREVENTION MEASURE UNIT
PROBLEM TO BE SOLVED: To provide a through-hole fire prevention measure structure capable of easily securing necessary fireproof performance without use of a high-performance thermal expansion material.SOLUTION: A fire prevention measure structure is provided on the side of an outer surface 3a of a division body 3 corresponding to a gap G between a through-hole 3H of the division body 3 and a long body 4 inserted therethrough. A thermal expansion material 6 is arranged around the long body 4. A thermosetting material 7 is arranged around the thermal expansion material 6. An annular holding frame 20 arranged in the state of covering at least the periphery of the thermosetting material 7 is fixed to the outer surface 3a of the division body 3.SELECTED DRAWING: Figure 2
【課題】高性能な熱膨張材を用いることなく必要な防火性能を容易に確保することができる貫通孔防火措置構造を実現する。【解決手段】区画体３の貫通孔３Ｈとそれに挿通される長尺体４との間の隙間Ｇに対応する区画体３の外面３ａ側に設けられる防火措置構造において、長尺体４の周囲に熱膨張材６が配置され、熱膨張材６の周囲に熱硬化材７が配置され、少なくとも熱硬化材７の周囲を覆う状態に配置される環状保持枠２０が区画体３の外面３ａに固定されている。【選択図】図２
