DRAIN PIPING JOINT
To provide sufficient fire resistance performance in a drain piping joint, suppress drainage noise, and suppress an increase in the outside diameter of the pipe.SOLUTION: A drain piping joint 100 comprises a pipe body 110 formed of a plurality of resin injection molded parts and placed in a through hole of a floor slab, an upper vertical pipe connection 120 that protrudes above the floor slab and connects an upper floor side drainage vertical pipe 220 that allows drainage from the upper floor to flow in, a lower vertical pipe connection 130 that protrudes below the floor slab and connects a lower floor side drainage vertical pipe 230 that allows drainage to flow down to the lower floor, and a horizontal branch pipe connection 140 that connects a drainage horizontal branch pipe above the floor slab. Between the horizontal branch pipe connection 140 and the lower vertical pipe connection 130 in the pipe body 110, formed is a swivel vane 114 that protrudes from the inner surface of the pipe body 110. A recess 112 corresponding to the swivel vane 114 is formed on the outer surface of the pipe body 110, and the recess 112 is filled with a thermally expandable refractory material 116.SELECTED DRAWING: Figure 1
【課題】排水配管継手において、耐火性能を十分に発揮させ、排水騒音を抑制し、管外径が大きくなることを抑制する。【解決手段】この排水配管継手１００は、複数の樹脂製の射出成形品で形成され、床スラブの貫通孔に配置される管本体１１０と、床スラブの上方に突出し上階からの排水を流入させる上階側排水立管２２０を接続する上立管接続部１２０と、床スラブの下方に突出し下階に排水を流下させる下階側排水立管２３０を接続する下立管接続部１３０と、床スラブの上方で排水横枝管を接続する横枝管接続部１４０とを備え、管本体１１０における横枝管接続部１４０と下立管接続部１３０との間には、管本体１１０の内面に突出する旋回羽根１１４が形成され、管本体１１０の外面にはこの旋回羽根１１４に対応するくぼみ１１２が形成され、このくぼみ１１２の部分に熱膨張性耐火材１１６が充填されている。【選択図】図１
