A platform for research: civil engineering, architecture and urbanism
To provide a fire-resistant drain trap that can be provided in a penetrating part without requiring rust-prevention treatment.SOLUTION: A drain trap 1 for a waterproof pan comprises: a thermoplastic resin inner pipe body part 10 which is formed into a cylindrical shape provided with a socket part 140 into which a downstream side pipe material is inserted and connected, and has an axis C extending in a vertical direction and attached to the waterproof pan; a thermoplastic resin connecting pipe part 50 which extends downward from the socket part 140 by inserting a lower end part of the socket part 140 into an upper end part; a thermal expansion member 60 which covers at least a part of the connecting pipe part 50 and expands due to heat to block a drainage flow channel; and a fiber mortar fireproof part 80 which covers the inner pipe body part 10, the connecting pipe part 50, and the thermal expansion member 60.SELECTED DRAWING: Figure 2
【課題】防錆処理を不要として、貫通部に設けることができる耐火性を備えた排水トラップを提供する。【解決手段】防水パン用の排水トラップ1であって、下流側管材が差し込まれて接続する受口部140を設けて筒状に形成されており、軸Cが上下の方向に延びていて防水パンに取り付けられる熱可塑性樹脂製の内管本体部10と、受口部140の下端部を上端部に差し込んで受口部140よりも下方へ延びた熱可塑性樹脂製の接続管部50と、少なくとも接続管部50の一部を覆っていて、熱で膨張して排水の流路を塞ぐ熱膨張部材60と、内管本体部10と接続管部50と熱膨張部材60を覆う繊維モルタル製の耐火部80と、を備えている。【選択図】図2
