DRAIN PIPING STRUCTURE
To provide drain piping structure equipped with a resin joint that can exhibit an optimal fire spread prevention effect (achieve desired fire-resistant structure) even in a deck slab.SOLUTION: In drain piping structure, thick slabs and thin slabs with different thicknesses are repeated at a predetermined pitch, and a resin joint 100 containing a thermal expansion material is installed on a deck slab DS having a flat upper surface. The resin joint 100 comprises: a resin upper member 140 that has one or more branch pipes and protrudes above the deck slab DS; a resin lower member 110 that is connected to a lower side of the upper member 140, and has an upper part buried in the deck slab DS and a lower part protruding below the deck slab DS when the resin joint 100 is installed on the deck slab DS; and a thermal expansion material. Then, the thermally expandable material is located in an expandable manner at a position of the thin slab.SELECTED DRAWING: Figure 3
【課題】デッキスラブであっても最適な延焼防止効果を発現（所望の耐火構造を実現）できる樹脂製継手が施工された排水配管構造を提供する。【解決手段】排水配管構造は、厚みが異なる厚肉スラブと薄肉スラブとが予め定められたピッチで繰り返され、上面が平面で形成されたデッキスラブＤＳに、熱膨張材を含む樹脂製継手１００が施工される。樹脂製継手１００は、１以上の分岐管を備え、デッキスラブＤＳの上方に突出する樹脂製の上部材１４０と、上部材１４０の下側に接続され、樹脂製継手１００がデッキスラブＤＳに施工された状態において上部がデッキスラブＤＳに埋設されるとともに下部がデッキスラブＤＳの下方に突出する樹脂製の下部材１１０と、熱膨張材と、を含む。そして、熱膨張材が薄肉スラブの位置において、膨張可能に存在する。【選択図】図３
