DRAINAGE PIPING JOINT AND DRAINAGE EQUIPMENT
To provide a drainage piping joint 100 which can prevent formation of a gap between a thermally expandable refractory material 116 and a sound absorbing material 151 and can prevent propagation of drainage sound into a living space.SOLUTION: The drainage piping joint comprises: a pipe body 110 with a pit 112 formed in an outer peripheral surface; the thermally expandable refractory material 116 embedded in the pit 112; and the sound absorbing material 151 wound around the pipe body 110. A seam of the sound absorbing material 151 in the circumferential direction of the pipe body 110 does not overlap the thermally expandable refractory material 116.SELECTED DRAWING: Figure 2
【課題】熱膨張性耐火材１１６と吸音材１５１との間に隙間が生じることを防ぎ、居室内まで排水音が伝播することを防ぐことができる排水配管継手１００を提供する。【解決手段】外周面にくぼみ１１２が形成された管本体１１０と、くぼみ１１２に埋め込まれた熱膨張性耐火材１１６と、管本体１１０の周囲に巻き付けられた吸音材１５１と、を備え、管本体１１０の周方向における吸音材１５１のつなぎ目は、熱膨張性耐火材１１６に対して重なっていない。【選択図】図２
