To provide a drainage piping member capable of appropriately closing a through-hole of a floor slab in fire disaster.SOLUTION: A drainage collective pipe 10 includes: a synthetic resin pipe body 12 having a through-pipe part 12b, an upper pipe part 12a, and an upper pipe connection part having a rubber ring socket shape; a thermal expansion part 30 provided in the through-pipe part; a cylindrical vibration isolation part 32 provided on an outer peripheral face of the through-pipe part so as to cover the thermal expansion part; and a cylindrical upper sound insulation cover 70 provided on an outer peripheral face of the upper pipe part. The vibration isolation part is formed by cylindrically sewing predetermined-shape mat members which are formed by interlocking predetermined-length first inorganic fibers each having a heatproof temperature of 800°C or higher, with sewing threads which are formed by second inorganic fibers each having a heatproof temperature of 800°C or lower.SELECTED DRAWING: Figure 5
【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、貫通管部１２ｂ、上管部１２ａおよびゴム輪受口形状の上管接続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、上管部の外周面に設けられる筒状の上部遮音カバー７０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５
