SOUND ABSORBING MATERIAL AND COLLECTIVE JOINT
To provide a sound absorbing material and a collective joint capable of easily holding a refractory material.SOLUTION: A collective joint 1 has a joint upper part 11 to which a first and second vertical pipes P1, P2 and a horizontal pipe P3 are connected, a joint lower part 12 with a cylindrical tube part 16 and a reduced diameter part 17, and a refractory material 19 provided on the joint lower part 12. A sound absorbing material 32 is attached to the joint lower part 12 of the collective joint 1. The sound absorbing material 32 has an inorganic fiber layer 41 and a flame-retardant material layer laminated in this order. The inorganic fiber layer 41 is arranged on the joint lower part 12 side.SELECTED DRAWING: Figure 1
【課題】耐火材を保持しやすくできる吸音材及び集合継手を提供する。【解決手段】集合継手１は、第１、第２の立管Ｐ１，Ｐ２及び横管Ｐ３が接続される継手上部１１と、円筒管部１６及び縮径部１７を備える継手下部１２と、継手下部１２に設けられた耐火材１９と、を備える。吸音材３２は、集合継手１の継手下部１２に取り付けられる。吸音材３２は、無機繊維層４１、難燃材層がこの順に積層され、無機繊維層４１が継手下部１２の側に配置されている。【選択図】図１
