DRAINAGE PIPING MEMBER AND FIREPROOF ZONE STRUCTURE
To provide a drainage piping member which can properly block a penetration hole of floor slab at a fire.SOLUTION: A drainage collection pipe 10 comprises a synthetic resin-made pipe main body 12 having a penetration pipe part being a portion arranged in a penetration hole 104 of a floor slab 102, a thermal expansion part 30 arranged at the penetration pipe part, and a cylindrical vibration insulation part 32 arranged at an external peripheral face of the penetration pipe part so as to cover the thermal expansion part. The vibration insulation part is formed by sewing a mat member having a prescribed shape which is formed by tangling a first inorganic fiber having a prescribed length whose heat resistance temperature is equal to 800°C or higher with a second inorganic fiber whose heat resistance temperature is equal to 800°C or higher.SELECTED DRAWING: Figure 1
【課題】火災時に床スラブの貫通孔を適切に閉塞できる排水配管部材を提供する。【解決手段】排水集合管１０は、床スラブ１０２の貫通孔１０４内に配置される部分である貫通管部を有する合成樹脂製の管本体１２と、貫通管部に設けられる熱膨張部３０と、熱膨張部を覆うように貫通管部の外周面に設けられる筒状の振動絶縁部３２とを備える。振動絶縁部は、耐熱温度が８００℃以上である所定長さの第１無機繊維を絡み合わせて形成した所定形状のマット部材を、耐熱温度が８００℃以上の第２無機繊維によって形成された縫糸で筒状に縫製することで形成されている。【選択図】図１
