RESIN-MADE JOINT
To provide a resin-made joint which can exert an optimum fire spread prevention effect (can obtain a desired first resistance structure) even if a slab is thin in a thickness.SOLUTION: A resin-made joint 100 includes: a resin-made upper member 140 having one or more branch pipes, and protruding upward of a thin-thickness slab; a resin-made lower member 110 connected to a lower side of the upper member 140, embedded into the thin-thickness slab at an upper part in a state in which the resin-made joint 100 is processed to the thin-thickness slab, and protruding downward of the thin-thickness slab at a lower part; and a thermal expansion material. In the thermal expansion material, an upper-part thermal expansion material 711 and a lower-part thermal expansion material 712 are separately provided at two points of an outer surface of the resin-made joint 100 in a vertical direction. The lower member 110 comprises a diameter-contacted part 118 at a lower side, the upper-part thermal expansion material 711 and the lower-part thermal expansion material 712 are provided at an upper side of the diameter-contracted part 118, and at least one of the upper-part thermal expansion material 711 and the lower-part thermal expansion material 712 is located in a position of the thin-thickness slab so as to be expandable.SELECTED DRAWING: Figure 3
【課題】薄肉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）できる樹脂製継手を提供する。【解決手段】樹脂製継手１００は、１以上の分岐管を備え、薄肉スラブ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が薄肉スラブに施工された状態において上部が薄肉スラブに埋設されるとともに下部が薄肉スラブ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。この熱膨張材は、樹脂製継手１００の外表面の上下２箇所に、上部熱膨張材７１１および下部熱膨張材７１２が上下方向に離隔して設けられ、下部材１１０は下側に縮径部１１８を備え、上部熱膨張材７１１および下部熱膨張材７１２は縮径部１１８よりも上側に設けられ、上部熱膨張材７１１および下部熱膨張材７１２の少なくとも一方が、薄肉スラブの位置で膨張可能に存在する。【選択図】図３
