Zusammenfassung: | To provide a fire compartment penetration structure facilitating construction and having excellent fire resistance even when piping cables are arranged in contact with a penetration hole arranged in a wall forming a fire compartment.SOLUTION: A fire compartment penetration structure has piping cables inserted through a penetration hole arranged in a wall forming a fire compartment. In the fire compartment penetration structure, a thermal expansion fireproof sheet is arranged along an inner face of the penetration hole, at least one of the piping cables contacts with the thermal expansion fireproof sheet arranged along the inner face of the penetration hole, and the sheet material is arranged on at least one side of the wall so as to cover a gas between the penetration hole and the piping cables.SELECTED DRAWING: Figure 8
【課題】防火区画を形成する壁に設けられた貫通孔に接して配管ケーブル類が設置されている場合でも、簡単に施工を行うことができ、耐火性に優れる防火区画貫通部構造を提供すること。【解決手段】防火区画を形成する壁に設けられた貫通孔を配管ケーブル類が挿通する防火区画貫通部構造であって、熱膨張性耐火シートが、前記貫通孔内面に沿って設置され、前記配管ケーブル類の少なくとも一つが、前記貫通孔内面に沿って設置された前記熱膨張性耐火シートに接し、シート材が、前記貫通孔と前記配管ケーブル類との隙間を覆うように前記壁の少なくとも一方に設置されていることを特徴とする、防火区画貫通部構造。【選択図】図8 |
