FIRE-RESISTING STRUCTURE OF PENETRATION PART
PROBLEM TO BE SOLVED: To provide a fire-resisting structure of a penetration part, which can prevent a thermal expansion fire-resisting device from coming off a fireproof partition body even when wiring and a piping material are subjected to force for moving them in the axial direction and can prevent a through hole from becoming a path of smoke.SOLUTION: A fire-resisting structure of a penetration part provided in a fireproof partition wall W of a building is constructed such that a wire conduit P is inserted in a through hole Wa and a thermal expansion fire-resisting device 11 is provided between the inner peripheral surface of the through hole Wa and the outer peripheral surface of the wire conduit P. In this fire-resisting structure of the penetration part, the thermal expansion fire-resisting device 11 is arranged to surround the outer peripheral surface of the wire conduit P with a gap Ka left therefrom and is fixed to the fireproof partition wall W. In the gap Ka, a filling material 21 is provided for closing the gap Ka while permitting movement of the wire conduit P in the axial direction relative to the thermal expansion fire-resisting device 11.SELECTED DRAWING: Figure 6
【課題】配線・配管材に軸方向へ移動させる力が加わっても、熱膨張性耐火具が防火区画体から外れることを防止することができるとともに、貫通孔が煙の経路になることを防止することができる貫通部の耐火構造を提供すること。【解決手段】建築物の防火区画壁Wに設けられた貫通部の耐火構造は、貫通孔Waに電線管Pが挿通され、貫通孔Waの内周面と電線管Pの外周面との間に、熱膨張性耐火具11が設けられてなるものである。この貫通部の耐火構造において、熱膨張性耐火具11は、電線管Pの外周面に対し間隙Kaを空けて取り囲むように配置されて防火区画壁Wに固定されている。間隙Kaには、熱膨張性耐火具11に対する電線管Pの軸方向への移動を許容しつつ間隙Kaを閉塞する充填材21が設けられている。【選択図】図6
